Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and in particular to a microfiltration wastewater treatment device based on the removal of turbidity from industrial wastewater. Background Technology

[0002] In the field of industrial wastewater treatment, turbidity removal is a key pretreatment step for achieving water purification and reuse. Microfiltration technology, with its uniform pore size and high interception efficiency, is widely used in such scenarios. However, in actual operation, traditional microfiltration equipment, such as fixed filter cartridges, filter screens, or simple vibrating screening devices, generally face the problem of easy clogging during the filtration process.

[0003] In existing static or simple dynamic filtration methods, suspended solid particles tend to accumulate rapidly on the filter media surface, forming a dense filter cake layer, and may even embed themselves inside the filter pores. This leads to a sharp increase in filtration resistance and a rapid decrease in flux. To solve the clogging problem, periodic backwashing or offline chemical cleaning is usually used. However, this not only increases the complexity and energy consumption of the equipment, but also forces the filtration process to be interrupted, affecting the overall processing efficiency and continuity. In addition, for deep filtration or fine filtration units, the adhesive impurities accumulated inside are even more difficult to remove effectively by conventional backwashing. After long-term operation, they are prone to caking, resulting in irreversible decline in filtration performance and shortening the life of the filter media. Although some equipment has tried to introduce mechanical cleaning methods such as scrapers and brushes, their movement trajectory is often simple, there are dead corners in the cleaning coverage, and the dynamic coordination between the cleaning action and the filtration process is insufficient. It is impossible to achieve real-time, active dispersion and peeling of the impurity layer on the filter surface while continuously filtering, resulting in a significant reduction in microfiltration efficiency. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention provides a microfiltration wastewater treatment device based on industrial wastewater turbidity removal.

[0005] To solve the above technical problems, the present invention provides the following technical solution: a microfiltration sewage treatment device based on industrial wastewater turbidity removal, comprising a treatment cylinder and an L-shaped sewage pipe installed on the top of the treatment cylinder, wherein a swing filter assembly is provided at the inner top of the treatment cylinder, and the swing filter assembly shakes and filters the sewage.

[0006] The swaying filter cartridge in the swaying filter assembly sways and drives the impurities after the wastewater is filtered. During the swaying process, the swaying filter assembly throws out the wastewater and at the same time, the filtered impurities sway and flow.

[0007] The inside of the swaying filter cartridge is also equipped with a rotating scraping component. The L-shaped scraper in the rotating scraping component scrapes and cleans the impurities in the filter holes of the swaying filter cartridge.

[0008] A fixed filter cartridge is provided at the bottom of the processing cylinder, and a torsional brush assembly is provided inside the processing cylinder. The torsional brush assembly is used to brush and clean the clogging impurities in the fixed filter cartridge. The torsional ring in the torsional brush assembly moves inside the fixed filter cartridge.

[0009] The fixed filter cartridge is equipped with a barrier filtration component inside. The barrier filtration component filters the wastewater by blocking it, and the triangular baffle plate in the barrier filtration component blocks and disperses the wastewater.

[0010] As a preferred embodiment of the present invention, the swing filter assembly includes a swing base and a spiral swing plate.

The spiral swing plate is movably connected between the tops of the L-shaped fixing plates through a rotating shaft. The swing cylinder is movably connected between the spiral swing plates through a connecting rotating rod. The L-shaped fixing plate and the connecting rotating rod are staggered.

[0011] The first motor is fixedly installed inside the swing base. The output end of the first motor is connected to a connecting rod that moves to the outside of the swing base via a rotating shaft. The connecting rod is fixedly installed with a first connecting rod. The first connecting rod is fixedly installed at the bottom of the swing cylinder. A swing filter cylinder is fixedly installed at the end of the swing cylinder away from the swing base.

[0012] As a preferred embodiment of the present invention, the rotary scraping assembly includes a second motor, the second motor is fixedly installed inside the swaying cylinder, a rotating shaft is fixedly installed at the output end of the second motor, and the top of the rotating shaft extends through into the swaying filter cylinder. An L-shaped scraper is fixedly installed at the top of the rotating shaft. Several scraping brushes are evenly arranged on the side of the L-shaped scraper near the swaying filter cylinder, and the scraping brushes clean the impurity particles that are blocked in the swaying filter cylinder.

[0013] As a preferred embodiment of the present invention, the bottom of the processing cylinder is connected to a fixed filter cylinder via a support rod. The torsional brushing assembly includes a support frame, a support ring, and a drive rod. The support frame is fixedly installed inside the processing cylinder. First fixed seats are fixedly installed at both ends of the support frame. Each first fixed seat is movably connected to a first rotating plate via a rotating shaft. An L-shaped base frame is fixedly installed at the top center of the support frame. A second fixed seat is fixedly installed on the L-shaped base frame. Second rotating plates are movably connected to both sides of the second fixed seat via rotating shafts. A second rotating rod is fixedly installed on the second rotating plate.

[0014] The top of the fixed filter cartridge is fixedly equipped with an inlet hopper, and the top of the inlet hopper is movably snapped with a filter cover. Support rings are movably sleeved on the outer periphery of the inlet hopper, and support plates are fixedly installed on the support rings. A first rotating plate is fixedly equipped with a first rotating rod. Both the first rotating rod and the second rotating rod are movably sleeved with connecting blocks at the ends near the inlet hopper. The connecting blocks are movably connected to the support plate through connecting shafts. A moving plate is fixedly installed on the side of the support ring away from the first fixed seat. A moving rod is fixedly installed on the moving plate, and a torsion ring is fixedly installed at the bottom end of the moving rod. Several cleaning brushes are evenly installed on the outer periphery of the torsion ring. An arc-shaped groove is opened on the top of the fixed filter cartridge, and the moving rod moves through the arc-shaped groove.

[0015] The support frame is fixedly mounted with a motor base, and a third motor is fixedly mounted inside the motor base. A pulley is fixedly mounted on the rotating shaft of the first fixed base, and a transmission belt is tensioned between the two pulleys. The output end of the third motor is fixedly mounted on one of the pulleys. A drain pipe with a solenoid valve is fixedly mounted at the bottom center of the fixed filter cartridge. A T-shaped discharge pipe is connected between the bottoms of the drain pipes. A drain port is connected to the bottom of the fixed filter cartridge.

[0016] As a preferred embodiment of the present invention, the blocking filter assembly includes an inclined scraper, which is uniformly and fixedly installed on the inner side of the torsion ring. A plurality of base rods are uniformly installed on the inner bottom of the fixed filter cylinder, and a triangular blocking plate is fixedly installed at the top of the base rods. A plurality of blocking brushes are uniformly installed on the outer periphery of the triangular blocking plate, and a plurality of blocking holes are uniformly opened on the triangular blocking plate. The inclined scraper moves and cleans the impurities on the blocking brushes.

[0017] Compared with the prior art, the beneficial effects that this invention can achieve are:

[0018] 1. In this invention, the first motor in the swaying filter assembly drives the swaying filter cylinder to sway rhythmically back and forth. The wastewater inside the swaying filter cylinder is subjected to significant centrifugal force and is accelerated and thrown towards the peripheral wall of the filter cylinder. This dynamic effect strongly propels the water flow to penetrate the micropores on the filter cylinder wall, achieving efficient preliminary solid-liquid separation. Larger particles of impurities are quickly trapped on the inner wall of the filter cylinder or at the inlet of the filter holes. The continuous swaying motion gives the trapped impurities a tangential driving force along the cylinder wall, preventing them from settling statically. Instead, they migrate and tumble continuously with the direction of cylinder wall movement. This dynamic effect not only significantly accelerates the filtration rate but also actively agitates and disperses the impurity layer mechanically, fundamentally preventing the accumulation and caking of impurities in local areas. This effectively avoids the risk of rapid blockage of the filter holes due to surface covering, ensuring the continuous and stable flux during the filtration stage and effectively preventing rapid blockage caused by the accumulation of impurities in local areas, thereby significantly improving the efficiency and continuity of filtration.

[0019] 2. In this invention, the rotating scraping component and the torsional brushing component work together to achieve synchronous online cleaning during the filtration process. The rotating scraping brush inside the swaying filter cartridge can immediately remove particles that are clogging the filter holes. The reciprocating torsional brushing on the inner wall of the fixed filter cartridge can peel off the attached substances in all directions. The rotating scraping brush can continuously loosen and peel off the filter hole blockages. On the other hand, the swaying of the swaying filter cartridge prevents the scraped-off impurities from re-attaching stably and moves rapidly to a lower position or slag discharge area under the action of centrifugal force and water flow. The cleaning mechanism that combines rotating scraping with dynamic shaking significantly enhances the anti-clogging and self-cleaning capabilities and ensures the stability of the filtration flux.

[0020] 3. In this invention, the ingenious linkage mechanism of the torsional brush assembly transforms the rotational drive into the reciprocating torsional motion of the cleaning brush along the inner wall of the fixed filter cartridge, forming a composite cleaning trajectory that combines circumferential and axial directions. This allows the cleaning brush to contact and scrape the edges of the filter holes from multiple angles, providing excellent loosening and peeling effects for fine particles with strong embedding and adhered sludge, achieving almost comprehensive cleaning without dead angles and greatly improving cleanliness.

[0021] 4. In this invention, the reciprocating oscillation of the first rotating plate is precisely converted into a reciprocating torsional motion at a defined angle that supports the fixed filter cartridge axis. The support ring, via a motion rod connected below, drives the torsion ring mounted on its inner side, causing the torsion ring to move along a pre-set arc-shaped groove trajectory on the inner wall of the fixed filter cartridge. The flexible cleaning brush mounted on the outer periphery of the torsion ring, along with this unique reciprocating torsional motion, continuously and comprehensively scrubs the entire inner wall of the fixed filter cartridge. This composite motion trajectory, combining circumferential scraping and axial oscillation, can efficiently peel off the residue adhering to the filter cartridge. The filter effectively loosens and removes impurities from the filter walls and filter pore edges, especially for highly embedded particles, thus fundamentally preventing progressive clogging of the filter pores and ensuring long-term stability of the filtration flux. Impurities removed by the cleaning brush are deposited at the bottom of the fixed filter cartridge under the influence of gravity and water flow. By opening the solenoid valve at the bottom of the cartridge on a timed or as-needed basis, the sludge collected here is discharged into the T-shaped discharge pipe below through the drain pipe, achieving regular and convenient cleaning of impurities. The entire process does not require interruption of the filtration operation, ensuring the continuity and high efficiency of the equipment operation.

[0022] 5. In this invention, the surface of the triangular baffle is densely covered with specially designed blocking holes, and a dense layer of blocking brushes is fitted around it. When the pre-filtered sewage falls to this point, it first impacts the inclined surface of the triangular baffle, and the water flow is diverted and diffused. Subsequently, as the water flow passes through the dense holes and brush layer, its path is forced to change repeatedly and generate tiny vortices. This process greatly increases the chance of residual fine particles in the water colliding and contacting with the blocking structure. Thus, through the dual action of mechanical interception and surface adsorption, it efficiently captures those tiny suspended solids and colloidal particles that easily penetrate ordinary filter screens, significantly improving the clarity of the effluent.

[0023] 6. In this invention, an inclined scraper corresponding to the position of each triangular baffle is installed inside the frame that reciprocates with the torsion ring. When the torsion ring moves, the inclined scraper repeatedly scrapes and combs the baffle brushes on the triangular baffles. This periodic mechanical agitation can promptly peel off and remove impurities accumulated between the bristles, keeping the baffle brushes fluffy and clean at all times. This ensures the long-term stability and high efficiency of its filtration performance, achieving an organic combination of fine filtration and automatic maintenance. It eliminates the tediousness of manual cleaning and ensures the reliability of the filtration effect.

[0024] 7. In this invention, dynamic separation is achieved through swing filtration, combined with real-time self-cleaning by rotating scraping. Wastewater then enters the fixed filter cartridge for deep filtration, and the filter cartridge is automatically cleaned by the torsion brush assembly. The blocking filtration assembly inside the fixed filter cartridge effectively blocks filtration and also has a self-cleaning function. Through mechanical linkage, the filtration and cleaning processes are carried out synchronously and continuously, which significantly improves the wastewater turbidity removal efficiency and the stability and durability of equipment operation.

[0036] To make the technical means, creative features, and achieved objectives and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0037] Example: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, a microfiltration wastewater treatment device for industrial wastewater turbidity removal includes a treatment cylinder 10 and an L-shaped wastewater pipe 11 installed on the top of the treatment cylinder 10. A swing filter assembly is installed at the top inner part of the treatment cylinder 10. The swing filter assembly filters the wastewater by shaking it. The swing filter cylinder 28 installed in the swing filter assembly swings the filtered impurities, causing the wastewater to be thrown out during the swinging process, while simultaneously causing the filtered impurities to flow through the swing. The swing filter assembly includes a swing base 20 and a U-shaped swing plate 25. The swing base 20 is fixedly installed at the center of the inside of the processing cylinder 10. An L-shaped fixing plate 24 is fixedly installed on the top of the swing base 20. A spiral swing plate 25 is movably connected between the tops of the L-shaped fixing plates 24 through a rotating shaft. A swing cylinder 27 is movably connected between the spiral swing plates 25 through a connecting rotating rod 26. The L-shaped fixing plates 24 and the connecting rotating rod 26 are staggered. The stable connection between the spiral swing plates 25 and the connecting rotating rod 26 allows the swing cylinder 27 to swing between the L-shaped fixing plates 24 with the swing base 20 as the center.

[0038] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A first motor 21 is fixedly installed inside the rocker seat 20. The output end of the first motor 21 is connected to a connecting rod 22 that moves to the outside of the rocker seat 20 via a rotating shaft. A first connecting rod 23 is fixedly installed on the connecting rod 22. The first connecting rod 23 is fixedly installed at the bottom of the rocker cylinder 27. A rocker filter cylinder 28 is fixedly installed at the end of the rocker cylinder 27 away from the rocker seat 20. An arc-shaped cover 29 is fixedly installed at the bottom center of the rocker filter cylinder 28. The arc-shaped cover 29 moves to the outside of the spiral rocker plate 25. The arc-shaped cover 29 is like an inverted umbrella, moving closely around the periphery of the spiral rocker plate 25, providing physical isolation and sealing protection for the bottom motion mechanism. It effectively prevents air from entering from above. During filtration, wastewater and impurities that may splash or seep down into the square swing filter cartridge 28 directly invade the precision moving parts such as the swing base 20, connecting rod 22, and hinge of the spiral swing plate 25 below. This avoids impurities getting stuck in the bearings or shafts, prevents wastewater from corroding the internal motor and transmission structure, and significantly improves the reliability and service life of the core drive components. During the swinging process, any wastewater that may flow down the filter cartridge wall or tiny particles that fall off from the filter holes will be guided and have their path changed by the curved surface of the arc-shaped cover 29 after encountering it. They will be mainly confined to the outside of the cover or guided to the preset collection area, rather than directly impacting or accumulating in the bottom movable gap, thus playing an auxiliary role in fluid guidance and diversion.

[0039] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5Wastewater first enters the treatment cylinder 10 through the L-shaped wastewater pipe 11 and flows to the swaying filter assembly. The wastewater is filtered by the swaying filter cylinder 28. During the filtration process, the first motor 21 in the swaying seat 20 drives the connecting rod 22 to rotate stably. The connecting rod 22 drives the swaying cylinder 27 and the swaying filter cylinder 28 connected to it to reciprocate around the pivot plate 25 through the first connecting rod 23. During the swaying process of the swaying filter cylinder 28, the wastewater is thrown against the filter cylinder wall by centrifugal force. The water flows through the filter holes to achieve preliminary solid-liquid separation, while larger particles of impurities are trapped on the inner wall of the filter cylinder or at the filter holes. The swaying motion also promotes the flow of impurities along the inner wall of the filter cylinder, avoiding local accumulation and blockage. During the swaying process of the swaying filter cylinder 28, the filtration of wastewater can be accelerated, and the swaying motion can also drive the wastewater to sway and move the filtered impurities, effectively preventing the filtered impurities from blocking the swaying filter cylinder 28.

[0040] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The swaying filter cartridge 28 is also equipped with a rotating scraping assembly. The L-shaped scraper 32 in the rotating scraping assembly scrapes and cleans impurities from the filter holes of the swaying filter cartridge 28. The rotating scraping assembly includes a second motor 30, which is fixedly installed inside the swaying cartridge 27. A rotating shaft 31 is fixedly installed at the output end of the second motor 30, and the top of the rotating shaft 31 extends through into the swaying filter cartridge 28. The L-shaped scraper 32 is fixedly installed at the top of the rotating shaft 31. Several scraping brushes 33 are evenly arranged on one side of the L-shaped scraper 32 near the swaying filter cartridge 28, and the scraping brushes 33 clean the impurities in the swaying filter cartridge 28. The filter cartridge uses a brushing motion to clean the impurities and particles. The scraping brush 33 rotates at high speed close to the inner wall of the filter cartridge, directly scraping and washing the impurities attached to or embedded in the filter holes. The rotational cleaning of the scraping brush 33 and the reciprocating shaking motion of the swaying filter cartridge 28 itself form an efficient synergy: on the one hand, the rotating scraping brush 33 can continuously loosen and peel off the filter hole blockages; on the other hand, the shaking of the filter cartridge prevents the scraped impurities from re-attaching stably and moves quickly to lower places or the slag discharge area under the action of centrifugal force and water flow. This cleaning mechanism that combines rotational scraping with dynamic shaking significantly enhances the anti-clogging and self-cleaning capabilities, ensuring the stability of the filtration flux.

[0041] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5After the wastewater is filtered by swaying for a period of time, in order to prevent the filter holes from clogging, the rotating scraping component operates synchronously. The second motor 30 installed in the swaying cylinder 27 drives the rotating shaft 31 to rotate, which in turn drives the L-shaped scraper 32 at the top of the rotating shaft 31 to rotate. The scraping brush 33 set on the L-shaped scraper 32 is closely attached to the inner wall of the swaying filter cylinder 28 and the filter hole area to rotate and scrape, peeling off the impurity particles that are stuck in the filter holes, so that they move with the water flow or settle down, keeping the filter holes unobstructed. The peeled-off particle impurities are swayed and collected in the swaying filter cylinder 28.

[0042] See Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 The bottom of the processing cylinder 10 is provided with a fixed filter cylinder 13. The inside of the processing cylinder 10 is provided with a torsional brush assembly, which is used to brush and clean the clogging impurities of the fixed filter cylinder 13. The torsional ring 58 in the torsional brush assembly is movable inside the fixed filter cylinder 13. The bottom of the processing cylinder 10 is connected to the fixed filter cylinder 13 through a support rod 12. The torsional brush assembly includes a support frame 40, a support ring 52 and a drive rod. The support frame 40 is fixedly installed inside the processing cylinder 10. The two ends of the support frame 40 are fixedly installed with first fixed seats 41. The first fixed seats 41 are movably connected to first rotating plates 42 through rotating shafts. An L-shaped base frame 43 is fixedly installed at the top center of the support frame 40. A second fixed seat 44 is fixedly installed on the L-shaped base frame 43. The two sides of the second fixed seat 44 are movably connected to second rotating plates 45 through rotating shafts. A second rotating rod 46 is fixedly installed on the second rotating plates 45.

[0043] See Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 A liquid inlet 50 is fixedly installed on the top of the fixed filter cartridge 13, and a filter cover 51 is movably snapped onto the top of the liquid inlet 50. A support ring 52 is movably sleeved on the outer periphery of the liquid inlet 50, and a support plate 53 is fixedly installed on the support ring 52. A first rotating plate 42 is fixedly installed with a first rotating rod 47. A connecting block 54 is movably sleeved at the end of the first rotating rod 47 and the second rotating rod 46 near the liquid inlet 50. The connecting block 54 is movably connected to the support plate 53 through a connecting shaft 55. A moving plate 56 is fixedly installed on the side of the support ring 52 away from the first fixed seat 41. A moving rod 57 is fixedly installed on the moving plate 56, and a torsion ring 58 is fixedly installed at the bottom end of the moving rod 57. Several cleaning brushes 59 are evenly installed on the outer periphery of the torsion ring 58. An arc-shaped groove 14 is opened on the top of the fixed filter cartridge 13, and the moving rod 57 moves through the arc-shaped groove 14.

[0044] See Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 A motor base 60 is fixedly installed on the support frame 40. A third motor 61 is fixedly installed inside the motor base 60. A pulley 62 is fixedly installed on the shaft of the first fixed base 41, and a transmission belt 63 is tensioned between the two pulleys 62. The output end of the third motor 61 is fixedly installed on one of the pulleys 62. A sewage pipe 16 with a solenoid valve 15 is fixedly installed at the bottom center of the fixed filter cartridge 13. A T-shaped discharge pipe 17 is connected between the bottoms of the sewage pipes 16. A drain port 18 is connected to the bottom of the fixed filter cartridge 13, and the filtered sewage is discharged through the drain port 18.

[0045] See Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 After being filtered by the swing filter cartridge 28, the wastewater flows downward into the fixed filter cartridge 13 located at the bottom of the treatment cartridge 10. The inlet hopper 50 at the top of the fixed filter cartridge 13 receives the water from above and is equipped with a movable filter cover 51 for auxiliary interception to maintain the filtration efficiency of the fixed filter cartridge 13. The twisting brush assembly starts working, and the third motor 61 on the support frame 40 drives the rotating shafts on the two first fixed seats 41 to rotate synchronously through the pulley 62 and the transmission belt 63, thereby driving the first rotating plate 42 to swing. The first rotating plate 42 is linked with the support plate 53 on the support ring 52 through the first rotating rod 47, the connecting block 54 and the connecting rotating shaft 55; at the same time, the top of the support frame 40 The second fixed seat 44 on the L-shaped base frame 43 is connected to the support plate 53 on the other side through the second rotating plate 45 and the second rotating rod 46, which converts the swing of the first rotating plate 42 into the reciprocating torsional motion of the support ring 52 around the axis of the fixed filter cylinder 13. The support ring 52 drives the torsion ring 58 to move along the arc groove 14 trajectory inside the fixed filter cylinder 13 through the moving plate 56 and the moving rod 57. The cleaning brush 59 on the outer periphery of the torsion ring 58 then brushes the inner wall of the fixed filter cylinder 13 to remove attached impurities and prevent the filter holes from clogging. The accumulated impurities can be collected through the drain pipe 16 with solenoid valve 15 at the bottom of the fixed filter cylinder 13 and discharged periodically through the T-shaped discharge pipe 17.

[0046] See Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10The fixed filter cartridge 13 is equipped with a barrier filtration assembly inside. The barrier filtration assembly filters sewage by blocking it. The triangular barrier plate 71 in the barrier filtration assembly blocks and disperses the sewage. The barrier filtration assembly includes an inclined scraper 74, which is uniformly fixedly installed inside the torsion ring 58. Several base rods 70 are uniformly installed at the bottom of the fixed filter cartridge 13, and the triangular barrier plate 71 is fixedly installed at the top of the base rod 70. Several blocking brushes 72 are uniformly installed on the outer periphery of the triangular barrier plate 71. Several blocking holes 73 are uniformly opened on the triangular barrier plate 71. The inclined scraper 74 moves relative to the blocking brushes 72 around the triangular barrier plate 71, continuously sweeping and scraping the blocking brushes 72 on its surface, thereby effectively removing the trapped impurities attached to the blocking brushes 72 and maintaining the filtration performance of the barrier structure.

[0047] See Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 Inside the fixed filter cartridge 13, the barrier filtration assembly further optimizes the filtration effect. The barrier brush 72 and the barrier holes 73 on the surface of the triangular barrier plate 71 form multi-level blocking and dispersion of the falling sewage, enhancing the collision and interception efficiency of fine particles. At the same time, the inclined scraper 74, which moves with the torsion ring 58, continuously scrapes the barrier brush 72 on the triangular barrier plate 71 during the torsion process, removing the impurities accumulated on its surface and maintaining the filtration performance of the barrier structure.

[0048] Working principle: Wastewater first enters the treatment cylinder 10 through the L-shaped wastewater pipe 11 and flows to the swaying filter assembly. The wastewater is filtered by the swaying filter cylinder 28. During the filtration process, the first motor 21 in the swaying seat 20 drives the connecting rod 22 to rotate stably. The connecting rod 22 drives the swaying cylinder 27 and the connected swaying filter cylinder 28 to reciprocate around the U-shaped swaying plate 25 as the pivot. During the swaying process of the swaying filter cylinder 28, the wastewater is thrown against the filter cylinder wall by centrifugal force. The water flows through the filter holes to achieve preliminary solid-liquid separation, while larger particles of impurities are trapped on the inner wall of the filter cylinder or at the filter holes. The swaying motion also promotes the flow of impurities along the inner wall of the filter cylinder, avoiding local accumulation and blockage. During the swaying process of the swaying filter cylinder 28, the filtration of wastewater is accelerated, and the swaying motion also drives the wastewater to sway and move the filtered impurities, effectively preventing the filtered impurities from blocking the swaying filter cylinder 28.

[0049] After the wastewater is filtered by swaying for a period of time, in order to prevent the filter holes from clogging, the rotating scraping assembly operates synchronously. The second motor 30 installed in the swaying cylinder 27 drives the rotating shaft 31 to rotate, which in turn drives the L-shaped scraper 32 at the top of the rotating shaft 31 to rotate. The scraping brush 33 set on the L-shaped scraper 32 is closely attached to the inner wall of the swaying filter cylinder 28 and the filter hole area to rotate and scrape, peeling off the impurity particles that are stuck in the filter holes, so that they move with the water flow or settle down, keeping the filter holes unobstructed. The peeled-off particle impurities are swayed and collected in the swaying filter cylinder 28.

[0050] After being filtered by the swing filter cartridge 28, the wastewater flows downward into the fixed filter cartridge 13 located at the bottom of the treatment cartridge 10. The inlet hopper 50 at the top of the fixed filter cartridge 13 receives the water from above and is equipped with a movable filter cover 51 for auxiliary interception to maintain the filtration efficiency of the fixed filter cartridge 13. The twisting brush assembly starts working, and the third motor 61 on the support frame 40 drives the rotating shafts on the two first fixed seats 41 to rotate synchronously through the pulley 62 and the transmission belt 63, thereby driving the first rotating plate 42 to swing. The first rotating plate 42 is linked with the support plate 53 on the support ring 52 through the first rotating rod 47, the connecting block 54 and the connecting rotating shaft 55; at the same time, the top of the support frame 40 The second fixed seat 44 on the L-shaped base frame 43 is connected to the support plate 53 on the other side through the second rotating plate 45 and the second rotating rod 46, which converts the swing of the first rotating plate 42 into the reciprocating torsional motion of the support ring 52 around the axis of the fixed filter cylinder 13. The support ring 52 drives the torsion ring 58 to move along the arc groove 14 trajectory inside the fixed filter cylinder 13 through the moving plate 56 and the moving rod 57. The cleaning brush 59 on the outer periphery of the torsion ring 58 then brushes the inner wall of the fixed filter cylinder 13 to remove attached impurities and prevent the filter holes from clogging. The accumulated impurities can be collected through the drain pipe 16 with solenoid valve 15 at the bottom of the fixed filter cylinder 13 and discharged periodically through the T-shaped discharge pipe 17.

[0051] The reciprocating torsional motion causes the cleaning brush 59 to form a composite motion trajectory with both circumferential and axial slight oscillations on the inner wall of the fixed filter cartridge 13. This trajectory can effectively prevent impurities from forming escape zones or accumulation ridges in the brushing direction, ensuring that the bristles can scrape the inner wall of the filter cartridge and the edge of the filter holes at different angles. For fine particles embedded in the filter holes and sludge with strong adhesion, the continuous reciprocating force can produce a loosening and peeling effect more effectively than unidirectional rotation, thereby achieving a near-complete cleaning without dead angles and greatly reducing the clogging rate of the filter holes.

[0052] Inside the fixed filter cartridge 13, the barrier filtration assembly further optimizes the filtration effect. The barrier brush 72 and the barrier holes 73 on the surface of the triangular barrier plate 71 form multi-level blocking and dispersion of the falling sewage, enhancing the collision and interception efficiency of fine particles. At the same time, the inclined scraper 74, which moves with the torsion ring 58, continuously scrapes the barrier brush 72 on the triangular barrier plate 71 during the torsion process, removing the impurities accumulated on its surface and maintaining the filtration performance of the barrier structure.

[0053] Dynamic separation is achieved through swing filtration, combined with real-time self-cleaning by rotating scraping; the wastewater then enters the fixed filter cartridge 13 for deep filtration, and the filter cartridge is automatically cleaned by the torsional brush assembly; the fixed filter cartridge 13 has a blocking filtration assembly for effective blocking filtration and also has a self-cleaning function. The filtration and cleaning processes are carried out synchronously and continuously through mechanical linkage, which significantly improves the wastewater removal efficiency and the stability and durability of equipment operation.

[0054] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
