Description

Technical Field

[0001] This invention relates to the field of sludge dewatering technology, and more specifically, to a sludge dewatering treatment device for a water purification plant. Background Technology

[0002] Water treatment plants continuously generate a large amount of excess sludge during the wastewater treatment process. This type of sludge has an extremely high water content, is bulky, and is prone to the growth of harmful microorganisms. Direct disposal not only incurs high transportation costs but also poses environmental pollution risks. Therefore, sludge dewatering has become a core part of the sludge disposal process in water treatment plants. Its core objective is to significantly reduce the water content of sludge through mechanical compression and other methods, thereby reducing the volume of sludge and laying the foundation for subsequent landfilling, incineration, or resource utilization.

[0003] In actual operation, the wastewater extruded from the sludge is directly introduced into the collection tank for temporary storage through a guide structure. Direct discharge of this wastewater would violate environmental emission standards, while recycling and reuse would affect water quality. Therefore, deep purification treatment of the wastewater is necessary. The industry commonly uses the addition of flocculants for purification. The collection tank is usually equipped with a dosing box for storing flocculants. After the wastewater is stored in the collection tank, the dosing box is opened to allow the flocculants to fall into the collection tank, and the wastewater is purified using the flocculants. However, the dosing box is usually fixed in a specific position in the collection tank (such as the top center or one side), so that the flocculants are always added to the collection tank from the same position. The flocculants added to the collection tank can only diffuse locally near the dosing point, making it difficult to quickly and evenly disperse throughout the wastewater in the entire collection tank. As a result, the flocculant concentration in some wastewater is too high, while the flocculant concentration in other wastewater is too low, which in turn affects the effectiveness of the flocculants. Summary of the Invention

[0004] The purpose of this invention is to provide a sludge dewatering treatment device for water purification plants to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A sludge dewatering treatment device for a water purification plant includes a base plate, a collection box installed on the upper surface of the base plate, a collection chamber opened in the collection box, a squeezing box rotatably installed on both sides of the collection box, a squeezing chamber opened in the squeezing box, a filter plate installed in the squeezing chamber, a filter cloth covered on the upper end of the filter plate, and opposing squeezing components installed on the upper surface of the base plate, the squeezing components being used to squeeze the sludge above the filter cloth.

[0007] The upper surface of the base plate is also equipped with a flipping component, which is used to drive the two extrusion boxes to flip synchronously.

[0008] A sliding plate is slidably installed inside the collection chamber. A sliding frame is installed on the upper end of the sliding plate.

[0015] The driving component includes a sliding plate that is slidably mounted on the upper surface of the base plate. The upper surface of each sliding plate is equipped with a first rack that meshes with the corresponding first gear. A second cylinder is mounted on the upper surface of the base plate. A horizontal plate is mounted on the output shaft of the second cylinder. Slide rods that connect to the corresponding sliding plates are mounted on both ends of the horizontal plate.

[0016] Preferably, a limiting rod is installed inside the collecting cavity, which is opposite to and passes through both ends of the sliding plate;

[0017] The moving component includes a threaded rod that is rotatably mounted inside the collection chamber and threaded through the sliding plate.

[0018] Preferably, one end of the threaded rod extends out of the collection box, and a third synchronous pulley is fitted onto the extended end of the threaded rod. A support is installed on the side wall of the collection box 110 facing the horizontal plate, and a motor is installed on the support. A fourth synchronous pulley is fitted onto the output shaft of the motor, and a second synchronous belt is fitted between the third synchronous pulley and the fourth synchronous pulley.

[0019] Preferably, a second rack is installed inside the collecting cavity;

[0020] The stirring assembly includes a rotating rod rotatably mounted at both ends of a sliding plate, with multiple stirring rods mounted on the outer side wall of the rotating rod, and a second gear meshing with a corresponding second rack mounted on the upper end face of the rotating rod.

[0021] Preferably, the outer wall of the extrusion box is equipped with a through rod that is opposite to and passes through the corresponding striking plate. The through end of the through rod is equipped with a through block. The through rod between the through block and the striking plate is fitted with a first spring. The side wall of the striking plate facing the lower end face of the extrusion box is equipped with a corresponding fixing rod. A fixing plate is installed between the two fixing rods. The side walls opposite to the two fixing plates are equipped with a mating block. The side walls opposite to the mating block are provided with a first inclined surface.

[0022] The striking assembly includes a mounting shaft that is rotatably mounted on the lower end face of the extrusion box. A circular plate 900 is fitted on the outer side wall of the mounting shaft. Multiple extrusion blocks are mounted on the outer side wall of the circular plate 900. The opposite side wall of the extrusion blocks is provided with a second inclined surface that cooperates with the first inclined surface.

[0023] Preferably, a third gear is fitted on the outer side wall of the mounting shaft, a sliding drive plate is installed on the lower end face of the extrusion box, a third rack that meshes with the corresponding third gear is installed at both ends of the drive plate, and multiple push rods are installed on the side wall of the sliding frame facing the drive plate.

[0024] Preferably, a positioning plate is installed on the lower end face of the extrusion box, and multiple positioning rods that penetrate the positioning plate are installed on the side wall of the drive plate facing the positioning plate. A positioning block is installed on the penetrating end of each positioning rod, and a second spring is sleeved on each positioning rod located between the drive plate and the positioning plate.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] 1. This invention drives the sliding frame and dosing box to move back and forth in the collection chamber via a moving component, so that the flocculant can be evenly added to different positions in the wastewater. This effectively avoids the problem of excessively high or low local concentrations caused by traditional fixed dosing methods, significantly improves the dispersion uniformity of the flocculant in the wastewater, thereby enhancing the flocculation and purification effect and improving the overall efficiency of wastewater treatment.

[0027] 2. In this invention, the sliding plate drives the stirring components at both ends to operate during the movement of the sliding plate. The meshing transmission between the second gear and the second rack causes the rotating rod and the stirring rod on it to rotate continuously, thereby realizing dynamic stirring of the wastewater in the collection chamber, promoting the rapid mixing of flocculant and wastewater, further optimizing the flocculation reaction conditions, and improving the uniformity and thoroughness of the purification treatment.

[0028] 3. In this invention, the reciprocating motion of the sliding frame drives the drive plate, which in turn drives the striking component to operate. This causes the striking plate to continuously strike the outer wall of the extrusion chamber, causing the chamber to vibrate. This effectively promotes the shedding of sludge adhering to the inner wall of the extrusion chamber, reduces sludge residue, improves sludge discharge efficiency, and reduces cleaning difficulty and maintenance frequency.

[0029] 4. In this invention, the filter plate can be detachably installed in the extrusion chamber via overlapping plates and bolts, making filter cloth replacement and cleaning operations simple. At the same time, the dosing box and the cover plate are connected by threads, which facilitates the replenishment and maintenance of flocculant. This design significantly improves the maintainability and service life of key components, reduces downtime, and helps maintain the long-term stable operation of the treatment device.

[0030] 5. This invention uses a protective box to seal and protect transmission components such as synchronous pulleys and synchronous belts, effectively preventing sewage and sludge from entering the transmission mechanism and avoiding malfunctions caused by corrosion or blockage. Combined with guide structures such as limit rods, slots, and blocks, it ensures the stability and accuracy of moving parts such as sliding plates and slides, thereby improving the reliability and durability of the entire equipment in humid environments.

[0043] To further understand the content of this invention, a detailed description of the invention will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative and not limiting of the invention.

[0044] The following is in conjunction with the appendix Figures 1-10 This embodiment will be described in further detail.

[0045] like Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 7As shown, a sludge dewatering treatment device for a water purification plant in this embodiment includes a base plate 100, a collection box 110 installed on the upper surface of the base plate 100, a collection chamber opened in the collection box 110, and a squeezing box 120 rotatably installed on both sides of the collection box 110, a squeezing chamber opened in the squeezing box 120, a filter plate 710 provided in the squeezing chamber, a filter cloth 720 covered on the upper end of the filter plate 710, and opposing squeezing components provided on the upper surface of the base plate 100, the squeezing components being used to squeeze the sludge above the filter cloth 720;

[0046] The upper surface of the base plate 100 is also provided with a flipping component, which is used to drive the two extrusion boxes 120 to flip synchronously.

[0047] A sliding plate 210 is slidably installed inside the collection chamber. A sliding frame 220 is installed on the upper end face of the sliding plate 210. A dosing box 140 for storing flocculant is installed on the upper end face of the sliding frame 220. A moving component is provided inside the collection chamber, which is used to drive the sliding frame 220 to reciprocate.

[0048] Both ends of the sliding plate 210 are equipped with stirring components. The reciprocating movement of the sliding plate 210 is used to drive the stirring components to stir the wastewater.

[0049] The extrusion box 120 has a striking plate 800 on its opposite side wall and a striking component on its lower end face. After the extrusion box 120 is flipped, the sliding plate 210 moves back and forth to drive the striking component to drive the striking plate 800 to strike the outer side wall of the extrusion box 120.

[0050] In this embodiment, drain pipes 550 are installed on the side walls of the squeezing chambers 120. The drain pipes 550 are installed on the outer side walls of the collection chamber 110 via bearings, and the drain pipes 550 are connected to the collection chamber to enable the two squeezing chambers 120 to be rotatably installed on both sides of the collection chamber 110. When sludge is added to the two squeezing chambers, the two squeezing components squeeze the sludge in the squeezing chambers, so that the wastewater in the sludge can be filtered out through the filter cloth 720. The filtered wastewater can flow into the collection chamber through the drain pipes 550, so that the collection chamber can collect the filtered wastewater. After the squeezing components have finished squeezing the sludge, the squeezing of the sludge by the two squeezing components needs to be released. Then, the flipping component drives the two squeezing chambers 120 to rotate synchronously, and the squeezing components release the sludge. The opening of the pressure chamber faces the bottom plate 100. At this time, the sludge that has been squeezed in the pressure chamber can be poured out from the pressure chamber to clean the sludge in the pressure chamber. Then, the dosing box 140 is opened and the flocculant in the dosing box 140 is added to the wastewater in the pressure chamber. At the same time, the moving component can drive the sliding frame 220 to move back and forth in the collection chamber through the sliding plate 210, so that the flocculant in the dosing box 140 can be added to the wastewater at different positions in the collection chamber. Compared with the existing ones, this sludge dewatering treatment device for water purification plants can avoid the flocculant in the dosing box 140 being added to the same position in the wastewater during actual use, which would result in the flocculant concentration in some wastewater being too high and the flocculant concentration in other wastewater being too low.

[0051] When the sliding plate 210 moves back and forth, the moving sliding plate 210 can drive two stirring components, so that the two stirring components can stir the wastewater in the collection chamber at different positions, thereby making the mixing effect of flocculant and wastewater better.

[0052] When the extrusion box 120 is in the overturned position, some sludge may adhere to the extrusion chamber, preventing the extrusion box 120 from emptying the sludge. When the sliding frame 220 is reciprocating, the extrusion box 120 is in the overturned position. At this time, the reciprocating movement of the sliding frame 220 can drive the striking component on the lower end face of the extrusion box 120. The striking component drives the striking plates 800 on both sides of the extrusion box 120 to continuously strike the outer wall of the extrusion box 120, thereby causing the extrusion box 120 to vibrate. When the extrusion box 120 vibrates, the sludge adhering to the side wall of the extrusion chamber can fall off the side wall of the extrusion chamber, thereby reducing the sludge residue in the extrusion chamber.

[0053] The outer wall of the collection box 110 is equipped with a drain pipe 111 that connects to the collection chamber. A first solenoid valve is installed inside the drain pipe 111. After the wastewater in the collection chamber is mixed with the flocculant, the first solenoid valve is opened so that the wastewater in the collection chamber can be discharged into the sedimentation tank through the drain pipe 111 for subsequent treatment. At this time, the two squeezing boxes 120 are driven to flip by the flipping component so that the openings of the two squeezing chambers face upward.

[0054] The dosing box 140 has a corresponding dosing tube 470 installed on its outer wall. Each dosing tube 470 is equipped with a second solenoid valve. When the two second solenoid valves are open, the liquid flocculant in the dosing box 140 is added to the collection chamber through the dosing tube 470.

[0055] The upper end of the dosing box 140 is threaded with a cover plate 200. When the cover plate 200 is removed from the dosing box 140, flocculant can be added into the dosing box 140.

[0056] In actual use, overlapping plates 700 are installed on the opposite side walls of the extrusion chamber. After the filter cloth 720 covers the filter plate 710, the two ends of the filter plate 710 are overlapped on the corresponding overlapping plates 700. Then, multiple bolts 730 are inserted through the filter plate 710 and threaded into the overlapping plates 700 to install the filter plate 710 and the filter cloth 720 in the extrusion chamber. When the bolts 730 are turned out from the overlapping plates 700, the filter plate 710 and the filter cloth 720 can be removed from the extrusion chamber. At this time, the filter plate 710 and the filter cloth 720 can be cleaned or replaced.

[0057] like Figure 1 As shown, in this embodiment, the extrusion assembly includes a mounting bracket 130 mounted on the upper surface of the base plate 100. Opposite first cylinders 131 are mounted on the upper surface of the mounting bracket 130. A mounting plate 132 is mounted between the output shafts of the two first cylinders 131. A mounting rod 133 is mounted on the lower surface of the mounting plate 132. An extrusion plate 134 is mounted on the lower end of the mounting rod 133.

[0058] In this embodiment, the mounting plate 132 is driven to move up and down by the first cylinder 131 on the mounting frame 130. When the mounting plate 132 moves down, it can drive the extrusion plate 134 to move down through the mounting rod 133. The extrusion plate 134 moves down and extends into the extrusion chamber, thereby extruding the sludge in the extrusion chamber. When the first cylinder 131 drives the mounting plate 132 to move up, it can drive the extrusion plate 134 to move up through the mounting rod 133, so that the extrusion plate 134 slides out of the extrusion chamber and is located above the extrusion box 120, releasing the extrusion of the sludge. At the same time, it does not affect the flipping of the extrusion box 120.

[0059] like Figure 1 and Figure 5 As shown, in this embodiment, a supporting plate 150 is installed on the upper end face of the base plate 100. A cavity is opened in the supporting plate 150. A first round shaft 500 with one end inserted into the cavity is installed on the side wall of the extrusion box 120 facing the supporting plate 150. The first round shaft 500 located in the cavity is fitted with a first synchronous wheel 501.

[0060] The flipping assembly includes a second round shaft 510 rotatably mounted at the lower end of the cavity. A second synchronous wheel 511 is sleeved on the outer wall of the second round shaft 510. A first synchronous belt 520 is sleeved between the first synchronous wheel 501 and the second synchronous wheel 511. The upper end face of the base plate 100 is provided with a driving member for driving the two second round shafts 510 to rotate synchronously.

[0061] In this embodiment, the first round shaft 500 is connected to the support plate 150 by a bearing. The first synchronous wheel 501 is fixedly sleeved on the first round shaft 500. The second round shaft 510 is installed in the side wall of the cavity by a bearing. The second synchronous wheel 511 is fixedly sleeved on the second round shaft 510. When the driving component drives the two second round shafts 510 to rotate synchronously, the second round shaft 510 can drive the second synchronous wheel 511 to rotate. The second synchronous wheel 511 then drives the first synchronous wheel 501 to rotate through the first synchronous belt 520. The first synchronous wheel 501 drives the first round shaft 500 to rotate. The rotation of the first round shaft 500 can drive the extrusion box 120 to rotate, thereby realizing the flipping of the extrusion box 120 and dumping the sludge in the extrusion cavity.

[0062] like Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, in this embodiment, one end of the second round shaft 510 extends out of the support plate 150, and the extended end of the second round shaft 510 is equipped with a first gear 530.

[0063] The driving component includes a slide plate 540 that is slidably mounted on the upper surface of the base plate 100. The upper surface of the slide plate 540 is equipped with a first rack 541 that meshes with the corresponding first gear 530. A second cylinder 450 is mounted on the upper surface of the base plate 100. A horizontal plate 240 is mounted on the output shaft of the second cylinder 450. Slide rods 600 that connect to the corresponding slide plate 540 are mounted at both ends of the horizontal plate 240.

[0064] In this embodiment, the first gear 530 is fixedly mounted on the second round shaft 510. When the output shaft of the second cylinder 450 drives the horizontal plate 240 to move, the movement of the horizontal plate 240 can drive the two slide plates 540 to move through the two slide rods 600. The movement of the two slide plates 540 can drive the two first racks 541 to move. The movement of the two first racks 541 can drive the two first gears 530 to rotate. The two first gears 530 then drive the two second round shafts 510 to rotate synchronously.

[0065] Among them, the upper end surface of the base plate 100 is provided with a T-shaped slot 251 along the moving direction of the slide plate 540, and the lower end surface of the slide plate 540 is provided with a locking block 542 that is locked into the slot 251. The slot 251 limits the locking block 542, making the movement of the slide plate 540 more stable.

[0066] In actual use, two bases 440 are installed on the upper surface of the base plate 100, and the second cylinder 450 is installed on the upper surface of the base plate 100 through the two bases 440.

[0067] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in this embodiment, a limiting rod 310 is installed inside the collection cavity, which is opposite to and passes through both ends of the sliding plate 210;

[0068] The moving component includes a threaded rod 300 that is rotatably mounted in the collection chamber and threaded through the sliding plate 210.

[0069] In this embodiment, the two ends of the threaded rod 300 are rotatably mounted in the corresponding side wall of the collection cavity through bearings. The two limiting rods 310 limit the sliding plate 210. When the threaded rod 300 rotates, the threaded rod 300 can drive the sliding plate 210 to reciprocate. The movement of the sliding plate 210 can drive the sliding frame 220 and the dosing box 140 to reciprocate in the collection cavity.

[0070] One end of the threaded rod 300 extends out of the collection box 110. A third synchronous pulley 420 is fixedly sleeved on the extended end of the threaded rod 300. A support 400 is installed on the side wall of the collection box 110 facing the horizontal plate 240. A motor 230 is installed on the support 400. A fourth synchronous pulley 410 is fixedly sleeved on the output shaft of the motor 230. A second synchronous belt 421 is sleeved between the third synchronous pulley 420 and the fourth synchronous pulley 410. The rotation of the output shaft of the motor 230 can drive the fourth synchronous pulley 410 to rotate. The fourth synchronous pulley 410 can then drive the third synchronous pulley 420 to rotate through the second synchronous belt 421, that is, the threaded rod 300 rotates.

[0071] The outer wall of the collection box 110 is equipped with a protective box 430. The third synchronous pulley 420, the fourth synchronous pulley 410 and the second synchronous belt 421 are all located inside the protective box 430. The protective box 430 can protect the third synchronous pulley 420, the fourth synchronous pulley 410 and the second synchronous belt 421.

[0072] In actual use, there is a certain gap between the squeezing box 120 and the collecting box 110, so that the protective box 430 will not affect the flipping of the squeezing box 120.

[0073] like Figure 2 and Figure 3 As shown, in this embodiment, opposing second racks 330 are installed inside the collection cavity;

[0074] The stirring assembly includes a rotating rod 320 rotatably mounted at both ends of the sliding plate 210. Multiple stirring rods 322 are mounted on the outer side wall of the rotating rod 320, and a second gear 321 that meshes with the corresponding second rack 330 is mounted on the upper end face of the rotating rod 320.

[0075] In this embodiment, the rotating rod 320 and the sliding plate 210 are connected by a bearing. The second gear 321 is fixedly installed on the upper end face of the rotating rod 320. When the sliding plate 210 moves back and forth in the collection chamber, the sliding plate 210 can drive the rotating rod 320 to move back and forth. At this time, the moving rotating rod 320 can rotate through the cooperation of the gear and rack. The rotation of the rotating rod 320 can drive multiple stirring rods 322 to rotate, so that the stirring rods 322 can mix and stir the wastewater at different positions in the collection chamber.

[0076] like Figure 1 , Figure 2 , Figure 8 , Figure 9 and Figure 10 As shown, in this embodiment, the outer wall of the extrusion box 120 is equipped with a through rod 910 that is opposite to and passes through the corresponding striking plate 800. The through end of the through rod 910 is equipped with a through block 920. The through rod 910 between the through block 920 and the striking plate 800 is fitted with a first spring 930. The side wall of the striking plate 800 facing the lower end face of the extrusion box 120 is equipped with a corresponding fixing rod 801. A fixing plate 802 is installed between the two fixing rods 801. The side walls opposite to the two fixing plates 802 are equipped with a mating block 803. The side walls opposite to the mating block 803 are provided with a first inclined surface.

[0077] The striking assembly includes a mounting shaft 810 that is rotatably mounted on the lower end face of the extrusion box 120. The outer side wall of the mounting shaft 810 is fitted with a circular plate 900. The outer side wall of the circular plate 900 is fitted with a plurality of extrusion blocks 901. The opposite side wall of the extrusion blocks 901 is provided with a second inclined surface that cooperates with the first inclined surface.

[0078] In this embodiment, the striking plate 800 can be installed on the outer wall of the extrusion box 120 via the through rod 910. The through block 920 intercepts the first spring 930, enabling the first spring 930 to be installed on the through rod 910. The mounting shaft 810 is installed on the lower end face of the extrusion box 120 via a bearing. The circular plate 900 is fixedly mounted on the mounting shaft 810. When the mounting shaft 810 rotates, it drives the circular plate 900 to rotate. The rotation of the circular plate 900 drives the extrusion block 901 to move towards the mating block 803. When the extrusion block 901 abuts against the mating block 803, the extrusion block 901 can impact the first inclined surface via the second inclined surface. The pressing action causes the mating block 803 to move away from the circular plate 900. The movement of the mating block 803, through the fixed plate 802 and the fixed rod 801, can drive the striking plate 800 away from the pressing box 120 and press the first spring 930, putting the first spring 930 in a compressed state. When the pressing block 901 on the circular plate 900 passes the mating block 803, the first spring 930 is released from compression. The first spring 930 pushes the striking plate 800 to strike the outer wall of the pressing box 120, causing the pressing box 120 to vibrate. When the mounting shaft 810 rotates continuously, the striking plate 800 can continuously strike the pressing box 120.

[0079] The outer side wall of the mounting shaft 810 is fixedly fitted with a third gear 811, and the lower end face of the extrusion box 120 is fitted with a sliding drive plate 820. The two ends of the drive plate 820 are fitted with third racks 821 that mesh with the corresponding third gears 811. The sliding frame 220 is fitted with a plurality of push rods 460 on the side wall facing the drive plate 820. When the sliding frame 220 drives the push rods 460 to move toward the corresponding drive plate 820, the push rods 460 can push the drive plate 820 to move. The movement of the drive plate 820 can drive the two third racks 821 to move. The movement of the third racks 821 can drive the third gears 811 to rotate, that is, the mounting shaft 810 rotates.

[0080] Among them, the lower end face of the extrusion box 120 is equipped with opposite protrusions 830 with a cross section of T, and the side wall of the drive plate 820 is provided with opposite grooves with a cross section of T. By inserting the protrusions 830 into the corresponding grooves, the drive plate 820 can be slidably installed on the lower end face of the extrusion box 120.

[0081] The lower end face of the extrusion box 120 is equipped with a positioning plate 840. The drive plate 820 is equipped with a plurality of positioning rods 841 that penetrate the positioning plate 840 on its side wall facing the positioning plate 840. The through end of the positioning rod 841 is equipped with a positioning block 842. The positioning rod 841 located between the drive plate 820 and the positioning plate 840 is fitted with a second spring 850. When the push rod 460 pushes the drive plate 820 to move, the sliding frame 220 will drive the push rod 460 away from the drive plate 820. At this time, the second spring 850 will reset the drive plate 820, so that the push rod 460 can continue to push the drive plate 820 to move.

[0082] In actual use, when the sliding plate 210 stops moving, the sliding plate 210 is located in the middle of the collection chamber.

[0083] In practical use, the sludge is first poured into the two squeezing chambers. Then, the mounting plate 132 is driven downward by the first cylinder 131. The downward movement of the mounting plate 132 drives the squeezing plate 134 downward via the mounting rod 133, thereby squeezing the sludge in the squeezing chamber by the squeezing plate 134. This allows the wastewater in the sludge to flow into the collection chamber through the filter cloth 720 and the drain pipe 550. After the sludge squeezing is completed, the first cylinder 131 drives the squeezing plate 134 to move above the squeezing box 120. The second cylinder 450 drives the horizontal plate 240 to move. The movement of the horizontal plate 240 drives the first rack 541 to move via the slide rod 600. The first rack 541 drives the second round shaft 510 to rotate via the first gear 530. The second round shaft 510, through the cooperation of the first synchronous pulley 501, the second synchronous pulley 511, and the first synchronous belt 520, allows the extrusion box 120 to flip, emptying the sludge from the extrusion chamber. At this time, the second solenoid valve is opened, allowing the flocculant in the dosing box 140 to be added... The medicine tube 470 can be added to the wastewater. Simultaneously, the motor 230, through the cooperation of the third synchronous pulley 420, the fourth synchronous pulley 410, and the second synchronous belt 421, drives the threaded rod 300 to rotate. The rotation of the threaded rod 300 drives the sliding plate 210 and the sliding frame 220 to reciprocate. The reciprocating movement of the sliding plate 210, through the cooperation of the second rack 330 and the second gear 321, allows the stirring rod 322 on the rotating rod 320 to stir the wastewater. When the sliding frame 220 reciprocates... During retraction, the push rod 460 on the sliding frame 220 can push the drive plate 820 to move. The drive plate 820, through the cooperation of the third rack 821 and the third gear 811, causes the mounting shaft 810 to rotate. The rotation of the mounting shaft 810, through the extrusion block 901 on the circular plate 900, can drive the striking plate 800 to continuously strike the outer wall of the extrusion box 120. Finally, the first solenoid valve is opened, so that the wastewater in the collection chamber can be discharged into the sedimentation tank through the drain pipe 111 for subsequent treatment.

[0084] In summary, the above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made within the scope of the claims of the present invention should be covered by the present invention.
