Description

Technical Field

[0001] This invention relates to the field of aquaculture equipment, and in particular to a microfiltration machine for water purification. Background Technology

[0002] Wastewater typically contains particulate impurities. Wastewater treatment often requires the use of microfiltration machines for water purification to separate these impurities from the water. For example, in aquaculture, it's necessary to separate aquatic waste and sludge from the water in the ponds. Some existing microfiltration machines for water purification use a filter drum installed inside a filter box, driven by a motor. During operation, wastewater flows through a pipe into the filter drum, then passes through the filter screen and falls into the filter box, while impurities remain inside the filter drum, thus achieving water-to-impurity separation.

[0003] However, the existing microfiltration machines used for water purification have a complex installation structure between the filter roller and the filter box. When the filter roller needs to be replaced, it is very inconvenient, time-consuming and labor-intensive. Especially in aquaculture systems that use the box as the aquaculture pond, if the maintenance of the microfiltration machine used for water purification takes too long, impurities and harmful substances in the aquaculture pond cannot be discharged in time, which will affect the health of aquatic products and seriously affect economic benefits.

[0004] It is evident that existing technologies still need improvement and enhancement. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the purpose of this invention is to provide a microfiltration machine for water purification, which aims to solve the problem of inconvenient replacement of filter rollers in existing microfiltration machines for water purification.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A microfiltration machine for water purification includes a filter chamber with a filter roller rotatably connected inside. A first through hole is provided on one side wall of the filter chamber, communicating with the interior of the filter roller. A second through hole is provided at the lower end of the filter chamber and on the outside of the filter roller, with the second through hole positioned below the height of the filter roller. The end face of the filter roller away from the first through hole is sealed. A drive assembly is detachably connected to the filter chamber, and the drive assembly is drively connected to the filter roller. A U-shaped groove is provided on the inner side wall of the filter chamber, with the opening of the U-shaped groove facing upward. Both ends of the filter roller are rotatably connected within the U-shaped groove.

[0008] In the microfiltration machine for water purification, a water receiving tank is provided inside the filter drum. The water receiving tank is fixed to the inner wall of the filter chamber, with its opening facing upwards. A slag discharge port is provided at the bottom of the water receiving tank, and a slag discharge pipe is connected to the slag discharge port. One end of the slag discharge pipe extends to the outside of the filter chamber. A flushing water pipe is fixed at the upper end or above the filter chamber. The flushing water pipe is positioned directly above the filter drum, and its central axis is parallel to the central axis of the filter drum. A nozzle is fixed on the flushing water pipe, and the nozzle is positioned facing the water receiving tank.

[0009] In the microfiltration machine for water purification, a U-shaped pipe clamp is fixed in the filter chamber, and the flushing water pipe is installed in the filter chamber through the U-shaped pipe clamp.

[0010] Alternatively, a U-shaped pipe clamp and a pipe sleeve are fixed at both ends of the corresponding flushing water pipe in the filter chamber, and the flushing water pipe is installed in the filter chamber through the U-shaped pipe clamp and the pipe sleeve.

[0011] In the microfiltration machine for water purification, the filter chamber has an inlet chamber on the side near the first through hole. The first through hole is located on the partition between the filter chamber and the inlet chamber, and an inlet pipe is connected to the inlet chamber. A U-shaped groove on the side of the filter chamber near the inlet chamber is located on the partition between the inlet chamber and the filter chamber, and the U-shaped groove is connected to the top surface of the partition. The rotating shaft is connected to a slag discharge pipe through a pipe joint located inside the inlet chamber.

[0012] In the microfilter for water purification, the lower edge of the first through hole is an arc concentric with the filter drum, and a sealing strip that fits against the inner wall of the filter drum is fixed on the first through hole.

[0013] In the microfiltration machine for water purification, a disinfection chamber is also provided on the side of the filtration chamber. A water tank is fixed inside the disinfection chamber. The water tank is connected to the filtration chamber through a second through hole. Several water pipes are provided on the top surface of the water tank. Disinfection components are installed inside the water pipes. An outlet pipe is provided on the disinfection chamber and outside the water tank.

[0014] In the microfilter for water purification, the height of the outlet end of the water pipe and the height of the outlet pipe are both lower than the height of the rotating shaft, and the height of the lowest position of the first through hole is lower than the height of the rotating shaft.

[0015] In the microfiltration machine for water purification, the filter drum is connected to hub-shaped rings at both ends. The outer surface of the rings is fixedly connected to the filter drum. A rotating shaft is installed at the center of the rings. Both ends of the rotating shaft are fixedly connected to the inner wall of the filter chamber. The rotating shaft is tubular. One end of the rotating shaft is sealed, and the other end is connected to the slag discharge pipe. The middle part of the rotating shaft is fixedly connected to the water receiving tank. The slag discharge port of the water receiving tank is connected to the inside of the rotating shaft.

[0016] In the microfiltration machine for water purification, the filter roller includes a cylindrical frame, a filter screen covering the outer surface of the cylindrical frame, and a protective net covering the outer surface of the filter screen. The ring is fixed on the cylindrical frame, and the drive assembly is connected to the cylindrical frame in a transmission manner.

[0017] In the microfiltration machine for water purification, the drive assembly includes a motor fixed on the filter chamber, a drive wheel mounted on the motor output shaft, and a driven wheel fixed to one end of the filter drum and connected to the drive wheel.

[0018] Compared with the prior art, this application has at least the following beneficial effects:

[0019] 1. By using a rotatable filter drum in the filter chamber and driving it with a drive assembly, when sewage passes through the filter drum, particulate impurities in the sewage are retained inside the filter drum due to the filtering effect of the filter drum. The filter drum is installed in the filter chamber through a U-shaped groove, and the flushing water pipe is connected to the filter chamber through a U-shaped pipe clamp. The drive assembly that drives the filter drum to rotate is detachably connected to the filter chamber. Therefore, it is more convenient to disassemble and assemble the filter drum when needed.

[0020] 2. Due to the drive of the filter drum by the drive assembly and the presence of a water collection trough inside the filter drum, particulate impurities adhering to the inner wall of the filter drum rotate with the filter drum and fall into the water collection trough. They are then discharged from the sludge discharge port into the filter chamber, thus achieving the filtration treatment of wastewater. The particulate impurities can be automatically discharged, making cleaning more convenient and extending the time required for manual cleaning of the filter drum.

[0021] 3. The design of the inlet chamber avoids the impact of sewage on the filter screen, thus extending its service life. The design of the disinfection chamber, with a water tank installed on one side of the bottom, and multiple water pipes on the top of the water tank, allows the filtered water to pass through the water tank and water pipes sequentially. The water pipes have a small diameter, resulting in a smaller flow rate, which allows the disinfection components installed inside the water pipes to disinfect the filtered water more thoroughly.

Detailed Implementation

[0029] This invention provides a microfiltration machine for water purification. To make the objectives, technical solutions, and effects of this invention clearer and more explicit, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the invention and are not intended to limit the scope of protection of the invention.

[0030] See Figures 1-4 A microfiltration machine for water purification includes a filter chamber 1.1, a filter roller 1.5 rotatably connected inside the filter chamber 1.1, a first through hole 1.8 on one side wall of the filter chamber 1.1 communicating with the interior of the filter roller 1.5, a second through hole 1.22 at the lower end of the filter chamber 1.1 and outside the filter roller 1.5, the second through hole 1.22 being lower than the height of the filter roller 1.5, and the end face of the filter roller 1.5 away from the first through hole 1.8 being sealed, and a drive assembly 1.4 on the filter chamber 1.1 being drively connected to the filter roller 1.5.

[0031] In the above description, a cylindrical filter roller 1.5 is installed inside the filter chamber 1.1. Both ends of the filter roller 1.5 are rotatably connected to the filter chamber 1.1, and the filter roller 1.5 can rotate under the drive of the drive assembly 1.4. A certain distance is maintained between the filter roller 1.5 and the filter chamber 1.1. The first through hole 1.8 communicates with the interior of the filter roller 1.5, and the second through hole 1.22 is located below the height of the filter roller 1.5. During use, wastewater enters the filter roller 1.5 through the first through hole 1.8. Under the influence of gravity and the centrifugal force generated by the rotation of the filter roller 1.5, the water passes through the filter roller 1.5, falls below it, and is discharged through the second through hole 1.22.

[0032] In a preferred embodiment, a U-shaped groove 1.21 is provided on the inner wall of the filter chamber 1.1, with the opening of the U-shaped groove 1.21 facing upwards. The two ends of the filter roller 1.5 are rotatably connected within the U-shaped groove 1.21. Specifically, the distance between the connection points of the two ends of the filter roller 1.5 is equal to the distance between the U-shaped grooves 1.21 on both sides of the inner wall of the filter chamber 1.1. The filter roller 1.5 is mounted at the bottom of the U-shaped groove 1.21 by its own gravity, requiring no additional fixing. Therefore, when manual cleaning or replacement of the filter roller 1.5 is required, it needs to be disassembled from the filter chamber 1.1. By providing a U-shaped groove 1.21 on the inner wall of the filter chamber 1.1, and mounting the filter roller 1.5 within the U-shaped groove 1.21 via a rotating shaft 1.55, disassembly and assembly of the filter roller 1.5 can be achieved simply by pulling it out of the U-shaped groove 1.21, making disassembly and assembly more convenient.

[0033] Specifically, the filter drum 1.5 has a water receiving trough 1.24 inside, which is fixed to the inner wall of the filter chamber 1.1. The opening of the water receiving trough 1.24 faces upward, and a slag discharge port (not marked in the figure) is provided at the bottom of the water receiving trough 1.24. A slag discharge pipe 1.9 is connected to the slag discharge port, and one end of the slag discharge pipe 1.9 extends to the outside of the filter chamber 1.1. Particulate impurities in the wastewater remain inside the filter drum 1.5 under the filtration action of the filter drum 1.5. As the filter drum 1.5 is driven to rotate by the drive assembly 1.4, the particulate impurities attached to the inner wall of the filter drum 1.5 rotate with the filter drum 1.5. When the particulate impurities reach a higher position, they overcome the centrifugal force generated by the rotation of the filter drum 1.5 under their own weight, and thus fall into the water receiving trough 1.24 and are discharged from the slag discharge port into the filter chamber 1.1, achieving wastewater filtration treatment. The particulate impurities can be automatically discharged, making cleaning more convenient and extending the manual cleaning time of the filter drum 1.5.

[0034] In the above, there is a gap between the two sides of the water receiving tank 1.24 and the inner wall of the filter roller 1.5, so that particulate impurities can pass through the gap.

[0035] In a preferred embodiment, a flushing water pipe 1.2 is fixed at the upper end or above the filter chamber 1.1. The flushing water pipe 1.2 is positioned directly above the filter drum 1.5, and the central axis of the flushing water pipe 1.2 is parallel to the central axis of the filter drum 1.5. A nozzle 1.3 is fixed on the flushing water pipe 1.2, and the nozzle 1.3 is positioned facing the water receiving tank 1.24. One end of the flushing water pipe 1.2 is sealed, and the other end is connected to a clean water source through a pipe, and a booster pump (not shown in the figure) is connected in series on the pipe. During use, the booster pump starts, allowing clean water from the water source to enter the flushing water pipe 1.2 and be sprayed from the nozzle 1.3 onto the outer surface of the filter drum 1.5. The clean water, under pressure from the booster pump, impacts the particulate impurities on the surface of the filter drum 1.5, causing them to fall into the water collection tank 1.24 and be discharged from the slag discharge port within the tank. This restores the filtration capacity of the filter drum 1.5 and prevents clogging. Furthermore, the clean water flushes the filter drum 1.5 in a reverse direction, improving its cleaning effect. This reverse direction means that the direction in which the wastewater to be filtered passes through the filter drum 1.5 is opposite to the direction in which the water used to clean it passes through the filter drum 1.5.

[0036] The water used to clean the filter roller 1.5 enters the water receiving tank 1.24, which dilutes the particulate impurities in the tank, facilitating their discharge from the sludge outlet. The flushing water pipe 1.2 can operate continuously, or periodically or intermittently.

[0037] In the above, when the water source is higher than the flushing water pipe 1.2, the flushing water pipe 1.2 may not be connected to the water source pipe, and the water flows under its own weight potential energy and sprays onto the filter roller 1.5 through the nozzle 1.3.

[0038] In the above, the nozzle 1.3 is preferably a clamp-type nozzle 1.3 structure. The flushing water pipe 1.2 is provided with several through holes along the axial direction for connecting with the nozzle 1.3. The clamp-type nozzle 1.3 structure can be connected by fastening it onto the corresponding through holes, making the disassembly and assembly of the nozzle 1.3 more convenient.

[0039] In a preferred embodiment, the filter roller 1.5 is connected to both ends by hub-shaped rings 1.54. The outer surface of the rings 1.54 is fixedly connected to the filter roller 1.5. A rotating shaft 1.55 is installed at the center of the rings 1.54. Both ends of the rotating shaft 1.55 are fixedly connected to the inner wall of the filter chamber 1.1. The rotating shaft 1.55 is tubular, with one end sealed and the other end connected to the slag discharge pipe 1.9. The middle part of the rotating shaft 1.55 is fixedly connected to the water receiving tank 1.24, and the slag discharge port of the water receiving tank 1.24 communicates with the interior of the rotating shaft 1.55. Thus, the filter roller 1.5 is connected to the rotating shaft 1.55 at both ends via the hub-shaped rings 1.54, and the rotating shaft 1.55 is fixed to the inner wall of the filter chamber 1.1 at both ends, achieving a rotatable connection between the filter roller 1.5 and the filter chamber 1.1. In practical applications, to reduce the friction between the ring 1.54 and the rotating shaft 1.55, a rolling bearing can be installed between the ring 1.54 and the rotating shaft 1.55. The ring 1.54 is designed in a hub shape, that is, the inner and outer circles of the ring 1.54 are hollowed out to allow sewage to pass through without affecting the sewage entering the filter drum 1.5.

[0040] In a preferred embodiment, the lower edge of the first through hole 1.8 is an arc shape concentric with the filter roller 1.5. A sealing strip 1.23 is fixed to the first through hole 1.8 and fits against the inner wall of the filter roller 1.5. One end of the sealing strip 1.23 is fixed to the edge of the first through hole 1.8, and the other end fits against the inner wall of the filter roller 1.5 on the outside of the ring 1.54, so that sewage will not leak from the filter roller 1.5 to the outside of the filter roller 1.5. In other words, by setting the sealing strip 1.23, it is ensured that all sewage enters the interior of the filter roller 1.5, that is, all sewage must be filtered by the filter roller 1.5 before reaching the second through hole 1.22.

[0041] See Figure 5 and Figure 6 In a preferred embodiment, the filter roller 1.5 includes a cylindrical frame 1.51, a filter screen 1.52 covering the outer surface of the cylindrical frame 1.51, and a protective net 1.53 covering the outer surface of the filter screen 1.52. The ring 1.54 is fixed to the cylindrical frame 1.51, and the drive assembly 1.4 is connected to the cylindrical frame 1.51 in a transmission manner. The outer surface of the cylindrical frame 1.51 is provided with perforated through holes. Figure 5The filter screen (shown as hexagonal holes) is used for wastewater to pass through. The filter screen 1.52 wraps around the entire outer surface of the cylindrical frame 1.51. A protective net 1.53 covers the outside of the filter screen 1.52 and is fixed to the outside of the cylindrical frame 1.51 by clamps or similar means. The strength of the cylindrical frame 1.51 and the protective net 1.53 is greater than the strength of the filter screen 1.52, clamping the filter screen 1.52 between them. During use, the cylindrical frame 1.51 and the protective net 1.53 maintain the shape of the filter screen 1.52 to prevent damage. To improve the filtration effect, a filter screen 1.52 with a larger mesh size can be used.

[0042] See Figure 1-4 In a preferred embodiment, the filter chamber 1.1 has a water inlet chamber 1.10 on the side near the first through hole 1.8. The first through hole 1.8 is located on the partition between the filter chamber 1.1 and the water inlet chamber 1.10, and a water inlet pipe 1.7 is connected to the water inlet chamber 1.10. The water inlet chamber 1.10 allows wastewater to enter first and then overflow into the filter drum 1.5 through the first through hole 1.8, preventing the wastewater from impacting the filter screen 1.52 and extending its service life. Furthermore, after the wastewater enters the water inlet chamber 1.10, some particulate impurities settle at the bottom of the water inlet chamber 1.10, thus reducing the amount of particulate impurities entering the filter drum 1.5.

[0043] To make the structure of the microfilter used for water purification more compact and to facilitate the disassembly of the sludge discharge pipe 1.9 and the rotating shaft 1.55, a U-shaped groove 1.21 on the side of the filter chamber 1.1 near the water inlet chamber 1.10 is provided on the partition between the water inlet chamber 1.10 and the filter chamber 1.1, and the U-shaped groove 1.21 is connected to the top surface of the partition. Another U-shaped groove 1.21 is provided on the inner wall of the filter chamber 1.1. The rotating shaft 1.55 is connected to the sludge discharge pipe 1.9 through a pipe joint, which is located inside the water inlet chamber 1.10. One end of the rotating shaft 1.55 is connected to the slag discharge pipe 1.9 via a pipe joint. When disassembling the filter drum 1.5, the slag discharge pipe 1.9 needs to be disassembled first. Since the pipe joint is located inside the water inlet chamber 1.10, there is a large space for disassembling the rotating shaft 1.55 and the slag discharge pipe 1.9. The U-shaped groove 1.21 is located on the partition between the water inlet chamber 1.10 and the filter chamber 1.1, which makes the distance between the end face of the filter drum 1.5 and the partition smaller, resulting in a compact structure. The U-shaped groove 1.21 is connected to the top surface of the partition, so it does not affect the removal of the rotating shaft 1.55 from the U-shaped groove 1.21. This achieves the purpose of a compact structure and convenient disassembly and assembly for the entire microfilter used for water purification.

[0044] The slag discharge pipe 1.9 can be connected to a press (not shown in the figure) at the end away from the slag discharge port, so that the press can dry the impurities into solids. These solid impurities can be used as farm fertilizer and are easy to transport and process. The excess water discharged by the press can be connected back to the water inlet chamber 1.10.

[0045] As mentioned above, when disassembling and assembling the filter roller 1.5, the flushing water pipe 1.2 needs to be removed first. To make the removal of the flushing water pipe 1.2 more convenient, the flushing water pipe 1.2 can be installed in the filter chamber 1.1 through a U-shaped pipe clamp. When disassembling the flushing water pipe 1.2, simply pull the flushing water pipe 1.2 out of the U-shaped pipe clamp for easy disassembly.

[0046] In a preferred embodiment, the drive assembly 1.4 includes a motor 1.41 fixed on the filter chamber 1.1, a drive wheel 1.42 mounted on the output shaft of the motor 1.41, and a driven wheel 1.43 fixed to one end of the filter drum 1.5 and driven by the drive wheel 1.42. The drive wheel 1.42 on the motor 1.41 and the driven wheel 1.43 on the filter drum 1.5 can be driven by a belt or chain, allowing the motor 1.41 to rotate the filter drum 1.5.

[0047] In a preferred embodiment, both the driving wheel 1.42 and the driven wheel 1.43 are gears. The motor 1.41 is detachably fixed to the filter chamber 1.1. The driving wheel 1.42 is positioned above the central axis of the driven wheel 1.43. Since the rotating shaft 1.55 for mounting the filter roller 1.5 is fixed to the filter chamber 1.1 via the U-shaped groove 1.21, and the driving wheel 1.42 is positioned above the central axis of the driven wheel 1.43, during use, the driving wheel 1.42 can press the rotating shaft 1.55 into the U-shaped groove 1.21, preventing it from jumping. This ensures that the filter roller 1.5 cannot be directly pulled out of the U-shaped groove 1.21 after installation. When it is necessary to disassemble the filter roller 1.5, the motor 1.41 must be disassembled first.

[0048] In a further preferred embodiment, an mounting plate 1.14 with an "n" or "h" shaped cross-section is also provided. The mounting plate 1.14 is detachably fixed to the inner wall of the filter chamber 1.1 by screws. The motor 1.41 and the drive wheel 1.42 are mounted on the mounting plate 1.14. Therefore, when it is necessary to disassemble or assemble the motor 1.41 and the drive wheel 1.42, the mounting plate 1.14 can be directly disassembled, making disassembly and assembly convenient.

[0049] Preferably, the screw holes on the mounting plate 1.14 for mounting screws are elongated through holes. During installation, the tightness of the meshing between the driving wheel 1.42 and the driven wheel 1.43 can be adjusted by adjusting the position of the screws in the screw holes.

[0050] In practical applications, the motor 1.41 can also be fixed to the outside of the filter chamber 1.1, with the output shaft of the motor 1.41 passing through the side wall of the filter chamber 1.1 and located inside the filter chamber 1.1. The drive wheel 1.42 is rotatably connected to the mounting plate 1.14, and the drive wheel 1.42 is detachably connected to the output shaft of the motor 1.41. In this embodiment, the output shaft of the motor 1.41 can be set as a splined shaft, and the inner hole of the drive wheel 1.42 is matched with the output shaft of the motor 1.41, making it easy to disassemble the motor 1.41 and the drive wheel 1.42. Furthermore, placing the motor 1.41 outside the filter chamber 1.1 avoids the influence of sewage. Before disassembling and assembling the filter roller 1.5, only the mounting plate 1.14 needs to be disassembled, without disassembling the motor 1.41, making the mounting plate 1.14 and the structure mounted on it lighter and easier to disassemble and assemble.

[0051] In practical applications, a transmission wheel can also mesh between the driving wheel 1.42 and the driven wheel 1.43.

[0052] In a preferred embodiment, a disinfection chamber 1.13 is further provided on the side of the filter chamber 1.1. A water tank 1.11 is fixed inside the disinfection chamber 1.13. The water tank 1.11 communicates with the filter chamber 1.1 through a second through-hole 1.22. A plurality of water pipes 1.20 are provided on the top surface of the water tank 1.11. A disinfection component 1.12 is installed inside each water pipe 1.20. A water outlet pipe 1.6 is provided on the disinfection chamber 1.13 and outside the water tank 1.11. Specifically, by setting up the disinfection chamber 1.13 and providing the water tank 1.11 on one side of its bottom, with multiple water pipes 1.20 on the top surface of the water tank 1.11, the filtered water sequentially passes through the water tank 1.11 and the water pipes 1.20. The smaller diameter of the water pipe 1.20 results in a smaller flow rate, allowing the disinfection component 1.12 installed inside to more thoroughly disinfect the filtered water. Specifically, the distance between the water and the UV disinfection component 1.12 remains relatively short as the water passes through the pipe, ensuring sufficient intensity for the UV disinfection component to kill microorganisms and achieve better disinfection. The disinfection component 1.12 is preferably an ultraviolet lamp, which emits ultraviolet light to irradiate and kill bacteria in the water, thus achieving disinfection.

[0053] In a preferred embodiment, the height of the outlet end of the water pipe 1.20 and the height of the outlet pipe 1.6 are both lower than the height of the rotating shaft 1.55, and the height of the lowest position of the first through hole 1.8 is lower than the height of the rotating shaft 1.55. This allows the water entering the filter drum 1.5 to be filtered quickly, and the filter drum 1.5 will not be immersed in water for a long time. The filtered particulate impurities are not affected by the water and can be better carried into the water receiving tank 1.24.

[0054] In practical applications, the filter roller 1.5 can be set to one or more, thereby improving its filtration capacity. In a preferred embodiment of this application, two filter rollers 1.5 are set, and the two filter rollers 1.5 are driven by the same drive wheel 1.42, so that when more than two filter rollers 1.5 are set, the number of motors 1.41 used can be reduced. The number of disinfection chambers 1.13 can also be set according to actual needs; for example, disinfection chambers 1.13 can be set on both sides of the filter chamber 1.1.

[0055] In practical applications, the filter chamber 1.1, the inlet chamber 1.10, and the disinfection chamber 1.13 are integrated into a single structure, formed by partitions within a single water tank. Alternatively, a top cover can be installed above the filter chamber 1.1, the inlet chamber 1.10, and the disinfection chamber 1.13 (not shown in the diagram).

[0056] In a preferred embodiment, the second through hole 1.22 is provided on the bottom surface of the filter chamber 1.1 and is connected to the disinfection chamber 1.13 through a U-shaped pipe joint. The water inlet pipe 1.7 is connected to the bottom surface of the water inlet chamber 1.10, so that when the filter chamber 1.1, the water inlet chamber 1.10 and the disinfection chamber 1.13 need to be cleaned, the U-shaped pipe joint and the water inlet pipe 1.7 can be removed to drain all the cleaning water.

[0057] In this invention, a rotatable filter roller 1.5 is used inside the filter chamber 1.1 and is driven by a drive assembly 1.4. The filter roller 1.5 has a water receiving groove 1.24 inside. When sewage passes through the filter roller 1.5, particulate impurities in the sewage are retained inside the filter roller 1.5 under the filtration effect of the filter roller 1.5, thus achieving sewage filtration and allowing the filter roller 1.5 to be used evenly, extending its service life. The filter roller 1.5 is installed in the filter chamber 1.1 through a U-shaped groove 1.21, and the flushing water pipe 1.2 is connected to the filter chamber 1.1 through a U-shaped pipe clamp. The drive assembly 1.4 that drives the filter roller 1.5 to rotate is detachably connected to the filter chamber 1.1, making it more convenient to disassemble and assemble the filter roller 1.5 when necessary.

[0058] Driven by the drive assembly 14, the filter roller 1.5 rotates, causing particulate impurities adhering to its inner wall to rotate and fall into the water receiving tank 1.24. These impurities are then discharged from the sludge discharge port into the filter chamber 1.1, thus achieving wastewater filtration. The automatic discharge of particulate impurities makes cleaning easier and extends the time required for manual cleaning of the filter roller 1.5. The inlet chamber 1.10 prevents wastewater from impacting the filter screen 1.52, extending its lifespan. The disinfection chamber 1.13, with a water tank 1.11 at one side of its bottom, and multiple water pipes 1.20 on its top surface, allows filtered water to pass sequentially through the water tank 1.11 and the water pipes 1.20. The smaller diameter of the water pipes 1.20 results in a smaller flow rate, allowing the disinfection assembly 1.12 inside the water pipes 1.20 to more thoroughly disinfect the filtered water.
