Description

Technical Field

[0001] This invention belongs to the field of solid waste treatment technology, specifically a dehydration treatment device for sheep manure. Background Technology

[0002] With the rapid development of the sheep farming industry towards large-scale and intensive operations, the large amount of manure generated during the breeding process has become a key issue restricting the industry's green and sustainable development. The indiscriminate dumping of untreated sheep manure not only breeds a large number of pathogenic microorganisms and parasite eggs, polluting the surrounding soil, water, and atmosphere, but also triggers environmental complaints from nearby residents and faces strict regulatory penalties. At the same time, sheep manure is rich in organic matter and nutrients such as nitrogen, phosphorus, and potassium, making it an ideal raw material for producing high-quality organic fertilizer. Through harmless treatment and resource utilization, not only can environmental pollution problems be solved, but also a cycle of planting and breeding can be achieved, improving the overall economic benefits of the livestock industry.

[0003] Among numerous manure treatment technologies, solid-liquid separation and dehydration is the primary step in achieving manure reduction and resource utilization. The screw extrusion solid-liquid separator, due to its simple structure, convenient operation, and high processing efficiency, has become the most widely used dehydration equipment in sheep farms. This equipment primarily uses the continuous rotation of internal screw blades to push the manure into the cylinder forward. During this pushing process, the screw blades exert a continuously increasing compressive force on the manure, forcing the water out through the pores of the mesh cylinder. The dehydrated solid manure residue moves towards the discharge port under the thrust of the screw, and is gradually released through a pressure regulating device consisting of a spring and a plug at the discharge port, ultimately exiting the equipment, thus achieving the separation of the solid and liquid phases.

[0004] However, sheep manure contains a large number of fine particles, undigested long fibers, and sticky colloidal substances. During the extrusion process, these substances easily become embedded in the pores of the mesh cylinder or form a dense colloidal blockage layer on the surface of the cylinder, preventing water from passing through normally. Once the mesh cylinder is blocked, the internal extrusion pressure of the equipment increases abnormally, not only significantly increasing the output moisture content and noticeably reducing the dehydration effect; more seriously, the machine must be stopped for cleaning after the mesh cylinder is blocked, requiring high-pressure water guns or other tools to unclog it. This process is labor-intensive, time-consuming, and severely disrupts production continuity, causing great inconvenience to the daily operations of the farm. Summary of the Invention

[0037] 2. The sheep manure dewatering treatment equipment described in this invention features seamless online replacement of either the first or second mesh cylinder. When the first mesh cylinder becomes clogged, it can be replaced online. The entire replacement process is fully automated, requiring no manual intervention or downtime, thus completely eliminating the long production interruptions caused by cleaning clogged mesh cylinders in traditional equipment. This not only significantly improves the effective working time and overall processing capacity of the equipment but also avoids problems such as manure accumulation and odor spread caused by untimely manure treatment, ensuring continuous and stable operation of manure treatment and reducing the operational management pressure and environmental risks of the farm.

[0038] 3. The sheep manure dewatering equipment described in this invention, through the cooperative design of the vertical plate and the limiting chamber, can reliably constrain the spliced ​​second mesh cylinder, preventing the second mesh cylinder from easily expanding due to material under high pressure extrusion conditions. This ensures the structural integrity and sealing of the mesh cylinder during the dewatering process, avoiding material leakage and reduced dewatering effect caused by mesh cylinder expansion. At the same time, the guiding and fitting design of the curved plate can automatically correct the reset error of the arc-shaped mesh plate, ensuring that adjacent arc-shaped mesh plates and vertical plates can be accurately aligned and tightly fitted, eliminating splicing gaps, preventing small particles and fibers from leaking from the gaps, and also ensuring that the vertical plate can be smoothly inserted into the limiting chamber, improving the reliability of the mesh cylinder replacement process.

[0057] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0059] A dewatering chamber 2 is fixed to the left side of the hopper 1; a first screen cylinder 21 is provided inside the dewatering chamber 2, and multiple rings are fixed to the outer ring of the first screen cylinder 21; a first guide tube 22 is installed below the first screen cylinder 21 at the bottom of the dewatering chamber 2; a ring plate 3 is fixed to the left side of the dewatering chamber 2, and the inner diameter of the ring plate 3 is the same as the inner diameter of the first screen cylinder 21; a processing chamber 4 is fixed to the right side of the hopper 1; a replacement mechanism is provided inside the processing chamber 4; a first motor is installed on the right side of the processing chamber 4 via a mounting bracket; a rotating shaft 41 is installed on the first motor, and the rotating shaft 41 extends into the dewatering chamber 2; a discharge mechanism is installed on the left side of the ring plate 3; the rotating shaft 41. Spiral blades 42 are fixed on the inner and outer rings of the dewatering chamber 2 and the material hopper 1. Part of the spiral blades 42 are located inside the first mesh cylinder 21 and are in contact with the top arc surface of the slider 13. Four first lead screws 23 are spirally driven on the outer ring of the first mesh cylinder 21, located at four positions on the top, bottom, left and right of the first mesh cylinder 21. The left side of the first lead screw 23 rotates on the ring plate 3, and the right side extends to the right side of the processing chamber 4 and is driven by the second motor. The bottom of the bottom first lead screw 23 is provided with a first groove 14 on the arc surface at the top of the slider 13, and the bottom first lead screw 23 is located in the first groove 14.

[0060] In this embodiment, the discharge mechanism includes a guide cylinder 5; the guide cylinder 5 is fixed to the outside of the ring plate 3, and the rotating shaft 41 passes through the guide cylinder 5; a side plate 51 is rotatably attached to the end of the rotating shaft 41, and the side plate 51 is fixed to the ring plate 3 by an L-shaped plate 52; a pressure plate 53 is attached to the left end of the guide cylinder 5, and a spring is connected between the pressure plate 53 and the side plate 51; the replacement mechanism includes a second mesh cylinder 6, and multiple rings are also fixed to the outer ring of the second mesh cylinder 6; the second mesh cylinder 6 is located in the processing chamber 4 to the right of the slider 13; the diameter of the second mesh cylinder 6 is the same as the diameter of the first mesh cylinder 21; the second mesh cylinder 6 is formed by splicing and attaching four arc-shaped mesh plates 61 together;

[0061] Each of the four curved mesh plates 61 has a semi-U-shaped groove 62 on its mating surface, and adjacent curved mesh plates 61 form a complete U-shaped groove after mating. The first lead screw 23 passes through the complete U-shaped groove inside the second mesh cylinder 6. Each curved mesh plate 61 has a curved guide plate 63 fixed on both sides. The ring plate 3 has a storage groove 31 on the side facing the curved guide plate 63. Each curved mesh plate 61 has a sliding plate 64 fixed on its outer ring. The sliding plate 64 slides in the slide chamber 65. Multiple springs connect the sliding plate 64 and the slide chamber 65. In the initial state, the springs compress the sliding plate 64, causing... Adjacent arc-shaped mesh plates 61 are fitted together; each of the slide chambers 65 has a drive block 66 fixed on its side, and a second lead screw 67 is screwed inside the drive block 66, with one side of the second lead screw 67 extending to the ring plate 3 and rotatably connected to the ring plate 3, and the other side extending to the right side of the processing chamber 4 and driven by a third motor; the first groove 14 has a second groove 15 on both sides located inside the slider 13, and the two second lead screws 67 located below are located in the second groove 15; the outer ring of the processing chamber 4 is equipped with uniformly arranged nozzles 43; a second guide tube 44 is installed below the second mesh cylinder 6.

[0062] In this embodiment, a baffle 45 is fixed on the right side of the spiral blade 42 of the rotating shaft 41, and the baffle 45 is located above the slider 13 and fits against the arc surface of the top of the slider 13; the diameter of the baffle 45 is slightly smaller than the inner diameter of the first mesh cylinder 21.

[0063] When dehydrating sheep manure, the first motor is started, which drives the rotating shaft 41 and the spiral blades 42 fixed on the rotating shaft 41 to rotate synchronously. Then, the collected manure is fed into the hopper 11 and falls naturally onto the arc surface at the top of the slider 13. Since a baffle 45 is fixed to the right side of the spiral blades 42 on the rotating shaft 41, and the diameter of the baffle 45 is slightly smaller than the inner diameter of the first mesh cylinder 21, the baffle 45 can effectively block the manure, preventing it from moving towards the processing chamber 4 on the right side of the slider 13, ensuring that all the manure can enter the dehydration chamber. The continuously rotating spiral blade 42 fits against the arc surface at the top of the slider 13, forming a closed conveying channel that smoothly pushes the feces falling on the arc surface to the left. Under the push of the spiral blade 42, the feces gradually enter the first mesh cylinder 21 on the left. As the spiral blade 42 continues to rotate, the feces are continuously pushed towards the discharge end of the first mesh cylinder 21. During this process, the squeezing pressure on the feces continuously increases, and the free water and capillary water in it are forcibly squeezed out and flow into the bottom of the dewatering chamber 2 through the mesh of the first mesh cylinder 21. Finally, it is discharged to the subsequent sewage treatment system through the first conduit 22.

[0064] Specifically, the end of the rotating shaft 41 is rotatably connected to the side plate 51, and the side plate 51 is fixed to the ring plate 3 by the L-shaped plate 52 to ensure the stability of the rotating shaft 41 during operation. The left end of the guide cylinder 5 is fitted with a pressure plate 53, and a spring is connected between the pressure plate 53 and the side plate 51. In the initial state, the elastic force of the spring causes the pressure plate 53 to block the left outlet of the guide cylinder 5. After the feces are dehydrated in the first mesh cylinder 21, they will enter the interior of the guide cylinder 5 through the ring plate 3. As the feces accumulate, the pushing force of the feces on the pressure plate 53 gradually increases. When the pushing force exceeds the preload of the spring, the pressure plate 53 will gradually separate from the guide cylinder 5, and the dehydrated solid fecal residue will be evenly discharged from the gap between the pressure plate 53 and the guide cylinder 5, realizing efficient separation of solid and liquid phases.

[0065] More specifically, when the first screen cylinder 21 becomes clogged due to long-term use, resulting in a significant increase in the output moisture content and a decrease in the dewatering effect, the feeding into the hopper 11 is stopped first, while the first motor continues to run. The spiral blades 42 gradually push the remaining feces in the first screen cylinder 21 and the hopper 1 towards the outlet of the dewatering chamber 2. After all the remaining feces have been pushed into the guide cylinder 5, the pressure plate 53 can be manually pushed to separate from the guide cylinder 5, and the feces in the guide cylinder 5 can be removed. Then, the first motor is stopped, and the first screen cylinder 21 can be replaced. When replacing the first screen cylinder 21, the electric push rod 16 is retracted first, and the electric push rod 16 drives the slider 13 along the rectangular hopper 1. 2. The inner wall gradually slides down to the bottom of the rectangular compartment 12. During this process, the first lead screw 23 at the bottom will completely move out of the first groove 14 at the top of the slider 13, and the two second lead screws 67 at the bottom will also completely disengage from the second groove 15 inside the slider 13. When the slider 13 moves to the bottom position, the electric push rod 16 stops running. Then, multiple second motors are started, driving the four first lead screws 23 to rotate synchronously in the same direction. Since the outer ring of the first mesh cylinder 21 is screwed with the first lead screw 23, the rotation of the first lead screw 23 will drive the first mesh cylinder 21 to move to the right along the axial direction. The first mesh cylinder 21 moves to the right along the outer surface of the spiral plate 42 and passes the baffle 45.

[0066] Since the second mesh cylinder 6 is composed of four arc-shaped mesh plates 61 spliced ​​together, the adjacent arc-shaped mesh plates 61 form a complete U-shaped groove after being attached. The first lead screw 23 passes through the complete U-shaped groove inside the second mesh cylinder 6, so the rotation of the first lead screw 23 is not affected by the second mesh cylinder 6. When the first mesh cylinder 21, which moves to the right, contacts the arc-shaped guide plate 63 on the left side of the multiple arc-shaped mesh plates 61, the end of the first mesh cylinder 21 will generate radial extrusion force on the arc-shaped guide plate 63. The multiple arc-shaped guide plates 63, which are extruded, will drive the corresponding arc-shaped mesh plates 61 away from each other. At this time, the semi-U-shaped grooves 62 on the adjacent arc-shaped mesh plates 61 also move synchronously with the arc-shaped mesh plates 61, gradually moving away from the first lead screw 23 and no longer contacting the first lead screw 23. The arc-shaped mesh plates 61 that move away from each other will drive the slide plate 64 to move into the slide chamber 65, while compressing the spring between the slide plate 64 and the slide chamber 65.

[0067] After the first net cylinder 21 is fully inserted into the open second net cylinder 6, the second motor is stopped from rotating the first lead screw 23. Then the third motor is started, which drives the second lead screw 67 to rotate. Since the second lead screw 67 is screwed to the drive block 66, the rotation of the second lead screw 67 will drive the drive block 66, the slide 65 and the slide plate 64 to move to the left. The multiple slide plates 64 drive the corresponding arc-shaped net plates 61 to move to the left, so that the arc-shaped net plates 61 gradually detach from the outer surface of the first net cylinder 21. When the multiple arc-shaped net plates 61 are completely detached from the first net cylinder 21, the compressed spring in the slide 65 will release its elasticity, pushing the slide plate 64 to gradually move out of the slide 65. The four arc-shaped net plates 61 gradually return to their initial positions and fit tightly together under the push of the slide plate 64, forming a complete second net cylinder 6 again.

[0068] Then, the third motor continues to drive the second lead screw 67 to rotate, causing the reassembled second mesh cylinder 6 to move to the left through the baffle 45 and spiral blade 42 into the dewatering chamber 2. When the left end of the second mesh cylinder 6 is in contact with the ring plate 3, the arc-shaped guide plate 63 on the left side of the arc-shaped mesh plate 61 will enter the receiving groove 31 opened in the ring plate 3, thus not affecting the contact between the left end of the second mesh cylinder 6 and the ring plate 3. Then, the third motor is stopped. Then, the electric push rod 16 is extended again, driving the slider 13 to move upward and return to the initial position, so that the first lead screw 23 at the bottom re-enters the first groove 14, and the two second lead screws 67 at the bottom re-enters the second groove 15. At this time, the replacement process of the first mesh cylinder 21 is completed, and the feces can be put back into the hopper 11 to continue the dewatering process. The first lead screw 23 and the second lead screw 67 are both made of stainless steel, which can effectively prevent corrosive substances in the feces from corroding or damaging them, and extend the service life of the equipment.

[0069] Furthermore, after the first mesh cylinder 21 is moved into the processing chamber 4, the nozzles 43 installed on the outer ring of the processing chamber 4 are connected to an external high-pressure water source. High-pressure water is sprayed evenly from the nozzles 43 onto the inner and outer surfaces of the first mesh cylinder 21 to thoroughly wash away the fine particles, long fibers, and colloidal substances that are clogging the mesh. The clogging material and residual feces that are washed off will be discharged with the water flow through the second conduit 44 at the bottom of the processing chamber 4, thereby achieving automatic cleaning and unclogging of the mesh of the first mesh cylinder 21.

[0070] When the second screen cylinder 6 becomes clogged after prolonged use, the first screen cylinder 21 has already been cleaned by the nozzle 43. At this time, the screen cylinder can be replaced again following the same procedure. Control the slider 13 to move down, and then control the second screw 67 to move the second screen cylinder 6 to the right. When the arc-shaped guide plate 63 on the right side of the arc-shaped screen plate 61 comes into contact with the cleaned first screen cylinder 21, it will be gradually opened by the first screen cylinder 21, and the first screen cylinder 21 will gradually insert into the moving second screen cylinder 6. After the second screen cylinder 6 completely covers the first screen cylinder 21, control the second screen cylinder 6 to stop moving, and then control the first screw 23 to move the first screen cylinder 21 to the left into the dewatering chamber 2. Finally, control the slider 13 to move up and reset, and the fecal dewatering process can continue. Through the alternating use and automatic cleaning of the two screen cylinders, the equipment can operate continuously without interruption.

[0071] Furthermore, by alternating between the first mesh cylinder 21 and the second mesh cylinder 6, the clogging problem caused by long-term use of the mesh cylinders can be effectively avoided, ensuring that water can be discharged normally through the mesh cylinder pores during the squeezing process. This keeps the moisture content of the dehydrated feces within a stable design range, ensuring that the quality of the feces dehydration treatment always meets the standards. This not only ensures that each batch of fecal residue reaches a relatively consistent dehydration standard, but also avoids adverse effects on subsequent composting, fermentation, transportation, and storage due to fluctuations in moisture content, laying a good foundation for the resource utilization of fecal waste.

[0072] Meanwhile, through the seamless online replacement of the first net cylinder 21 or the second net cylinder 6, when the first net cylinder 21 becomes clogged, it can be replaced online. The entire replacement process is fully automated, requiring no manual intervention or downtime, thus completely eliminating the long-term production interruptions caused by cleaning clogged net cylinders in traditional equipment. This not only significantly improves the effective working time and overall processing capacity of the equipment, but also avoids problems such as accumulation and odor spread on the farm due to untimely manure treatment, ensuring the continuous and stable operation of manure treatment and reducing the operational management pressure and environmental risks of the farm.

[0073] As an embodiment of the present invention; the outer ring surface of the two-to-one-attached arc-shaped mesh plates 61 is fixed with a vertical plate 7. If adjacent arc-shaped mesh plates 61 are attached, adjacent vertical plates 7 are also attached; the outer ring of the first mesh cylinder 21 is provided with a limiting chamber 71, and the limiting chamber 71 is U-shaped and fixed on the ring plate 3; the limiting chamber 71 corresponds to the vertical plates 7 that are attached to each other.

[0074] In this embodiment, each of the limiting chambers 71 has two curved plates 72 that bend to opposite sides fixed on one end face of the vertical plate 7.

[0075] In this embodiment, each of the two adjacent surfaces of the upright plates 7 has an elongated groove; a steel wire rope 73 is provided in the elongated groove, and the two ends of the steel wire rope 73 are respectively fixed in the elongated grooves of the two upright plates 7; the outer ring of the first mesh cylinder 21 has ball bearings rotating around it.

[0076] During the replacement and operation of the mesh cylinder, the vertical plates 7 fixed to the outer ring surface of the adjacent arc-shaped mesh plates 61 will move synchronously with the arc-shaped mesh plates 61; when the first mesh cylinder 21 is gradually inserted into the second mesh cylinder 6, and the multiple arc-shaped mesh plates 61 are squeezed and spread apart radially, the vertical plates 7 fixed to each other will also separate synchronously; when the second mesh cylinder 6 is separated from the outer surface of the first mesh cylinder 21, the spring in the slide 65 pushes the slide plate 64 to reset, causing the multiple arc-shaped mesh plates 61 to re-adhere to each other, at which time the vertical plates 7 on the adjacent arc-shaped mesh plates 61 will also adhere to each other.

[0077] Specifically, as the reassembled second mesh cylinder 6 gradually moves into the dewatering chamber 2, the U-shaped limiting chamber 71 fixed on the ring plate 3 corresponds one-to-one with the adjacent vertical plates 7. As the second mesh cylinder 6 continues to move to the left, the adjacent and tightly fitted vertical plates 7 gradually insert into the corresponding limiting chamber 71. When the left end face of the second mesh cylinder 6 is completely fitted with the ring plate 3, the adjacent fitted vertical plates 7 are also completely inserted into the limiting chamber 71. The limiting chamber 71, through radial constraint on the vertical plates 7, can effectively prevent the radial force generated when the spiral blades 42 push the material to the left from expanding the second mesh cylinder 6.

[0078] More specifically, since two curved plates 72, bent in opposite directions, are fixed to one end face of the limiting chamber 71 facing the upright plate 7, during the movement of the upright plate 7 towards the limiting chamber 71, the upright plate 7 will first contact the inclined curved surface of the curved plate 72; if the adjacent upright plates 7 are not completely fitted, the guide curved surface of the curved plate 72 will generate a lateral thrust on the misaligned upright plates 7, pushing the upright plates 7 to gradually align and fit tightly, while simultaneously driving the corresponding arc-shaped mesh plate 61 to further fit into place. Subsequently, the upright plate 7 will move along the guide curve of the curved plate 72. The curved mesh plate 61 enters the limiting chamber 71. Since a steel wire rope 73 is connected to the long groove on the opposite side of the adjacent vertical plates 7, and the two ends of the steel wire rope 73 are fixed to the inner wall of the long groove of the two vertical plates 7 respectively, when the curved mesh plate 61 drives the vertical plates 7 to separate from each other, the steel wire rope 73 will be gradually straightened. When the steel wire rope 73 reaches its limit length, it will prevent the vertical plates 7 from continuing to separate, thereby limiting the maximum separation distance of the curved mesh plate 61 and preventing the curved mesh plate 61 from separating from other curved mesh plates 61 without restriction.

[0079] Furthermore, since the outer ring of the first mesh cylinder 21 is equipped with ball bearings, as the first mesh cylinder 21 is gradually inserted into the second mesh cylinder 6, the sliding friction between the first mesh cylinder 21 and the second mesh cylinder 6 will be converted into the rolling friction of the ball bearings, which greatly reduces the friction between the two and reduces the wear on the surface of the mesh cylinder.

[0080] Furthermore, the design of the vertical plate 7 and the limiting chamber 71 provides reliable radial constraint for the spliced ​​second mesh cylinder 6, preventing it from easily expanding due to material under high-pressure extrusion conditions. This ensures the structural integrity and sealing of the mesh cylinder during dewatering, avoiding material leakage and reduced dewatering effect caused by mesh cylinder expansion. At the same time, the guiding and fitting design of the curved plate 72 automatically corrects the reset error of the arc-shaped mesh plate 61, ensuring that adjacent arc-shaped mesh plates 61 and vertical plate 7 can be precisely aligned and tightly fitted, eliminating splicing gaps and preventing small particles and fibers from leaking out of the gaps. It also ensures that the vertical plate 7 can be smoothly inserted into the limiting chamber 71, improving the reliability of the mesh cylinder replacement process.

[0081] As an embodiment of the present invention; the outer ring surface of the rotating shaft 41 located in the processing chamber 4 is provided with a driven cylinder 8; the left side of the driven cylinder 8 is closed and fixed on the rotating shaft 41; the right side of the driven cylinder 8 is provided with a cylinder 83, and the driven cylinder 8 rotates inside the cylinder 83; a spiral brush layer 81 is fixed on the outer ring of the driven cylinder 8, and the spiral direction of the spiral brush layer 81 is opposite to the spiral direction of the spiral blade 42.

[0082] In this embodiment, the right end of the processing chamber 4 is fixed with uniformly arranged pipes 82, and the pipes 82 are connected to the inner cavity of the cylinder 83; the outer ring of the driven cylinder 8 is provided with uniformly arranged spray holes.

[0083] When the clogged first mesh cylinder 21 is moved to the designated position inside the processing chamber 4, the driven cylinder 8 fixed on the rotating shaft 41 is located inside the first mesh cylinder 21, and the spiral brush layer 81 on the outer ring of the driven cylinder 8 contacts the inner ring surface of the first mesh cylinder 21; at this time, the second mesh cylinder 6 is normally performing fecal dehydration in the dehydration chamber 2, and the first motor continuously drives the rotating shaft 41 to rotate. While the rotating shaft 41 drives the spiral blades 42 inside the dehydration chamber 2 to rotate, it also synchronously drives the driven cylinder 8 inside the processing chamber 4 to rotate; the right end of the driven cylinder 8 is rotatably supported inside the cylinder 83 to ensure that the driven cylinder 8 can rotate stably with the rotating shaft 41; because the spiral direction of the spiral brush layer 81 is... The spiral blades 42 have completely opposite spiral directions. The rotating spiral brush layer 81 will uniformly brush the inner surface of the first mesh cylinder 21 from all directions, effectively scraping off the sticky colloids, tangled long fibers, and fine particles embedded in the mesh holes that are attached to the inner ring of the mesh cylinder. For the feces remaining in the first mesh cylinder 21, as well as the dirt that falls into the first mesh cylinder 21 from the mesh holes during the brushing process, the reverse-rotating spiral brush layer 81 will generate an axial thrust to the right, continuously pushing these dirt to the right end of the first mesh cylinder 21, and finally falling from the right opening of the first mesh cylinder 21 to the bottom of the treatment chamber 4, and being discharged from the equipment through the second conduit 44 along with the cleaning wastewater.

[0084] Specifically, while mechanically scrubbing the first mesh cylinder 21, an external high-pressure water source is connected to the pipe 82 at the right end of the treatment chamber 4. The high-pressure water flows into the inner cavity of the cylinder 83 through the pipe 82 and then into the driven cylinder 8, which rotates in conjunction with the cylinder 83. When the driven cylinder 8 is filled with high-pressure water, the water flow is sprayed out at high speed through the nozzles evenly arranged on the outer ring of the driven cylinder 8, directly acting on the inner ring surface of the first mesh cylinder 21. Since the driven cylinder 8 is in a continuous rotating state, the water flow sprayed from the nozzles forms a rotating water curtain, which performs a thorough water jet scrub of the inner ring of the first mesh cylinder 21. At the same time, the water flow sprayed from the nozzles passes through the spiral brush layer 81, washing away the residual feces and dirt trapped between the bristles of the spiral brush layer 81, keeping the spiral brush layer 81 clean.
