One side of the coagulation tank 10 is a sludge service tank (not shown) in which sludge separated from sewage or sewage generated from an industrial facility or a general household, waste water, or the like is introduced and accommodated.

In the internal space of the service tank, the first agglomeration proceeds while stirring the introduced sludge and the inorganic coagulant, and the sludge firstly agglomerated in the service tank is transferred to the coagulation tank 10 by a transfer pump.

The agglomeration tank 10 is formed to have a predetermined internal space, the internal space is divided into at least three spaces. In these three spaces, a flow adjusting tank (not shown) for adjusting the flow rate of the sludge conveyed from the service tank, and a rapid stirring tank (not shown) for agglomeration of the sludge with an organic flocculant and the like through the flow adjusting tank. And a slow stirring tank (not shown) for separating the sludge mixed with the polymer in the rapid stirring tank with water, respectively.

Of course, the flow rate adjusting tank and the rapid and slow stirring tank formed in the inner space of the coagulation tank 10 may be configured to be formed in the form of a tank instead of the inner space of the coagulation tank 10.

The agitation tank 10 is agitated by the stirring unit and the stirring unit for stirring the sludge and the polymer compound by a power provided from a stirring power unit for providing a stirring power for stirring the sludge with the flocculating agent A sludge dispensing nozzle for transferring the sludge to the main body 30 may be further mounted.

The agglomeration tank 10 may be further equipped with a sensing and adjusting means for detecting the amount of the sludge introduced into the inner space, and a coagulant having an appropriate ratio is added to the agglomeration tank 10 according to the amount of the detected sludge. Aggregation of the sludge may be further progressed in the internal space of).

The sludge agglomerated in the inner space of the coagulation tank 10 is transferred to the main body 30 and is discharged in the form of a cake while being separated from water through a concentration and dehydration process in the main body 30.

The water separated from the sludge in the main body 30 is drained to the treatment plant or transferred to the service tank to proceed to the dehydration, it is possible to further remove the solids contained in the water.

The main body 30 may be configured as one, or may be configured as a plurality for the repeated concentration and dehydration process of the sludge.

The main body 30 is configured with a screen 31 forming an outer shape, and the fixing plate (35 in FIG. 2) and the fluid plate (36 in FIG. 2), which will be described later, alternate in the inner space of the screen 31. It is installed repeatedly.

The screen 31 has a cylindrical shape lying in a substantially horizontal direction while having an internal space as a whole, and at one end of the screen 31 is a screw mounted in the internal space of the screen 31 (33 in FIG. 2). The driving unit 32 that provides the rotational power of) is mounted.

The screen 31 is concentrated in the sludge inlet 311 and the inner space of the main body 30 to provide a passage for the sludge conveyed from the agglomeration tank 10 to the internal space of the main body 30 and Sludge discharge port 312 is provided to provide a passage for discharging the sludge in the form of dehydrated cake to the outer space of the main body 30.

The screen 31 may further include a cleaning nozzle for cleaning the sludge existing between the water discharge gaps. That is, when the sludge is deposited between the water discharge gaps, it is possible to prevent the sludge from sticking by spraying the washing water with the washing nozzles to secure a gap for water discharge.

By washing the sludge, it is possible to prevent or prevent the phenomenon of clogging the water discharge gap, it has the advantage that the discharge of water is smooth. Of course, the cleaning nozzle may not be formed, but it is preferable that a configuration is formed for smooth cleaning of the water discharge gap.

Referring to FIG. 2, a back pressure plate housing 60 is disposed between the screen 31 and the driver 32. The back pressure plate housing 60 is formed in the form of a hexahedron having a predetermined internal space.

Of course, the back pressure plate housing 60 may be configured to have a polyhedron or a cylindrical shape instead of a hexahedron, but should be configured to have a certain internal space.

In addition, the lower surface of the back pressure plate housing 60 is formed with the sludge discharge port 312 in which the sludge conveyed by the rotational movement of the screw 33 is discharged in the form of a cake.

The back pressure plate 61 is positioned in the inner space of the back pressure plate housing 60. The back pressure plate 61 has a predetermined thickness and the center of the left side, ie, the portion adjacent to the screw 33, is cut off by an area corresponding to the cross-sectional area of the rotating shaft of the screw 33, as shown in the drawing. The rotating shaft of 33 is formed to penetrate.

In addition, the left side central portion of the back pressure plate 61, that is, inclined surface of the back pressure plate 61 is formed slanted so that the thickness is thinner toward the outside from the portion through which the rotating shaft of the screw 33 passes. It is formed to be discharged along.

The sludge is guided by the left side of the back pressure plate 61 while the sludge is moved to the inner space of the back pressure plate housing 60, and the sludge is formed on the bottom surface of the back pressure plate housing 60 by its own weight. It is discharged to the outer space of the main body 30 through the discharge port 312.

As the sludge is guided by the back pressure plate 61, the sludge is prevented from flowing into the inner space of the driving part 32. By preventing the inflow of the sludge into the inner space of the drive unit 32 has the advantage of preventing the extension of life and breakage of the drive unit (32).

The back pressure plate housing 60 may be configured to be integrally formed with the screen 31, and may be mounted to the screen 31 by a fastening member or the like.

In addition, the screen 31 is equipped with a crimping unit 40 that provides interlocking power for the transfer of the sludge introduced into the interior space of the screen 31. The pressing unit 40 will be described later.

A collecting tank for collecting the sludge discharged in the form of a cake from the sludge discharge port 312 at the lower side of the screen 31, and a collecting water for collecting water separated from the sludge by concentration and dehydration of the sludge. More tanks may be installed.

Of course, by additionally adding the functions of the collection tank and the collection tank to the sludge service tank, it will be possible to omit a separate collection tank and the collection tank.

Looking at the internal configuration of the main body 30, a screw 33 is installed in the inner space of the screen 31 is axially coupled with the drive unit 32 to rotate by the rotational power provided from the drive unit 32 do.

The screw 33 is formed to have a screw blade 331 of the thread form on the outer surface of the cylindrical shape lying in the horizontal direction while having a certain diameter. The screw blade 331 is formed so that the gap becomes narrower toward the direction in which the sludge discharge port 312 is located.

As such, when the screw blade 331 is formed to narrow the gap toward the sludge discharge port 312, the sludge is dehydrated while concentrating. That is, the space in which the sludge is accommodated is gradually reduced by the interval between the screw blades 331 and the rotational axis of the screw 33, thereby compressing the sludge and discharging the water contained in the sludge to reduce the water content of the sludge. Let's go.

 The screen 31 is equipped with a split plate 34 for dividing the internal space into a plurality of spaces. The divided plate 34 is formed in a plate shape having a predetermined thickness, and divides the inner space of the screen 31 into a plurality of spaces in the longitudinal direction.

The connection part 41 which is a piston part which moves under the power provided by the said power part 42 is formed in the lower side.

As the fluid plate 36 is connected to the connection part 41, the fluid plate 36 is flowed by the power provided by the power unit 42. By the flow of the flow plate 36, a gap for discharging moisture is secured, and the sludge conveyed by the rotational movement of the screw 33 can be smoothly transferred.

When the flow plate 36 flows by the pressing unit 40, the flow plate 36 translates in a direction crossing with the conveying direction of the sludge. Referring to the drawings, the sludge is moved from the sludge inlet 311 toward the sludge discharge port 312, ie from right to left by the rotational movement of the screw 33.

When the screw 33 rotates, the sludge moves from the right side to the left side of the screw 33 in the longitudinal direction, and the flow plate 36 flows in the cross direction with the moving direction of the sludge. . That is, the flow plate 36 flows in the vertical direction and the moving direction of the sludge while flowing in the vertical direction.

In addition, the screw 33 is to perform the function of concentrating and dehydrating while transporting the sludge by the rotary motion, the pressing unit 40 to perform the function of pressing the sludge by the translational movement in the vertical direction do.

On the other hand, a part of the screen 31 in which the sludge discharge port 312 is formed is provided with a second pressing unit 50 for pressing the sludge to be conveyed. The second pressing unit 50 performs a function of additionally compressing the sludge conveyed by the rotational movement of the screw 33 at high pressure.

The second crimping unit 50 may be mounted along a virtual circle formed outside the rotation range of the screw blade 331 or mounted in plurality.

The second compression unit 50 is configured to include a second power unit 51 in the form of a cylinder as a whole, and a moving part 52 in the form of a piston as a whole.

The second power unit 51 may be configured to use the same fluid as the fluid used in the power unit 42 formed in the crimping unit 40, and may also be configured to use other types of fluids. .

The screw unit 33 rotates by the power provided by the driving unit 32 of the screw 33 while the movement unit 52 translates by the power provided by the second power unit 51. By pressing the sludge conveyed by the lower the moisture content it is to perform the function of smoothing the transport of the sludge.

Hereinafter, the configuration of the fixing plate 35, the flow plate 36, and the pressing unit 40 will be described with reference to FIGS. 3 and 4.

The fixing plate 35 is formed in a ring shape in which a central portion is cut off while having a predetermined thickness as a whole, and fixing portions 351 formed at both upper and lower half sides are installed in the interior space of the screen 31. It is fixed to the fixing bar 313 is mounted in the interior space of the screen 31.

The fixing part 351 is formed to be integrally formed with the fixing plate 35 so as to extend in the outward direction, and the fixing part 351 has a hole having a predetermined diameter and is formed in the fixing part 351. The fixing part 351 is fixedly mounted in the inner space of the screen 31 while the fixing bar 313 penetrates the hole to be formed.

A plurality of fixing plates 35 are fitted to the fixing bars 313, and a spacer 37 is interposed between the fixing plates 35 and the fixing plates 35 to maintain a predetermined gap. The spacer 37 is mounted to maintain the gap between the fixing plate 35 and the fixing plate 35 by the thickness thereof.

In addition, the flow plate 36 is interposed between the fixing plate 35 and the fixing plate 35. The flow plate 36 is formed in the shape of a circular ring having a thickness of a predetermined portion and a central portion thereof.

The flow plate 36 is mounted in the interior space of the screen 31 while the flow portion 361 formed on both sides of the upper half is fixed to the flow bar 314 installed in the interior space of the screen 31.

The flow portion 361 is formed integrally with the flow plate 36 and extends in the outward direction, and a hole having a predetermined diameter is formed in the center thereof. As the flow bar 314 penetrates the hole, the flow plate 36 is mounted in the interior space of the screen 31.

The flow bar 314 is made of a round bar shape lying in the horizontal direction while having a certain diameter, both ends are fixedly coupled to both sides of the inner surface of the screen 31, respectively.

At this time, the flow bar 314 is mounted so as to be able to move in a direction crossing the sludge conveying direction so that the flow plate 36 crosses the sludge conveying direction by the power of the pressing unit 40. It is configured to allow movement in the direction.

That is, the flow bar 314 is formed in a quantity corresponding to the number of the flow portion 361 and the corresponding cross section, while being located in the longitudinal direction of the screen 31 in the interior space of the screen 31 Both ends are fixedly fixed to the screen 31.

An ablation area formed at the center of the fixed plate 35 and the flow plate 36 is somewhat larger than the outer diameter of the screw 33, so that the screw blade 331 rotates when the screw 33 rotates. The outer surface and the fixed plate 35 or the fluid plate 36 is configured not to contact each other.

In addition, while the screw 33 is configured to penetrate the central portions of the fixed plate 35 and the flow plate 36, the sludge is fixed to the fixed plate (when the sludge is transferred by the rotational movement of the screw 33). 35) and the fluidized plate 36 is compressed to some extent to have an effect of dehydration.

In detail, the sludge is conveyed to a space between the inner surface of the central portion of the fixed plate 35 and the flow plate 36 and the outer surface of the screw 33. At this time, the sludge is moved through a narrow space between the inner surface of the central portion of the fixed plate 35 and the flow plate 36 and the outer surface of the screw 33, and a certain amount of compression is applied so that dehydration of the sludge proceeds to a certain degree. It is composed.

Both sides of the upper half of the flow plate 36 are combined with the pressing unit 40 to form a flow portion 361 to which power is transmitted. While the connection portion of the pressing unit 40 is connected to the flow portion 361, the flow plate 36 is translated by the power transmitted from the pressing unit 40, and crosses the moving direction of the sludge.

As such, the pressing unit 40 applies a certain amount of compression to the sludge by moving in a direction intersecting with the direction of movement of the sludge by a translational motion which is a different motion from the rotation of the screw 33.

Since the pressing unit 40 moves in the direction of movement of the sludge and crosses, the pressing unit 40 presses the sludge to a certain degree, thereby facilitating the transport of the sludge, and has the advantage of efficient concentration and dehydration of the sludge.

In addition, the pressing unit 40 is controlled separately from the screw 33 to be able to control the movement speed irrespective of the rotational movement of the screw 33, the amount and state of the sludge or the screw 33 Depending on the size of the) will have the advantage that can be controlled at the most suitable movement speed.
