Description

Technical Field

[0001] This invention belongs to the technical field of handheld floor scrubbers, and more specifically, relates to a handheld floor scrubber with an integrated wastewater tank solid-liquid separation device. Background Technology

[0002] Handheld floor scrubbers are portable cleaning devices that integrate water spraying, roller scrubbing, and real-time wastewater suction. The machine is designed for handheld operation, without any vertical support pole. It relies on hand grip to operate the machine and complete the floor cleaning operation. It can achieve simultaneous washing, scrubbing, and vacuuming of hard floors, leaving no water stains after cleaning. It is a miniaturized floor cleaning appliance that can replace traditional mops and rags.

[0003] A handheld floor scrubber with an integrated wastewater tank and solid-liquid separation device has been found to have at least the following technical problems: Firstly, the solid-liquid separation effect is not good. The sewage tanks of existing floor scrubbers are mostly single storage structures, lacking targeted solid-liquid separation design. The scum and suspended solids in the sewage are directly mixed with the sewage, which not only makes it easy for impurities to clog the drain outlet when the sewage is poured out, but also makes it difficult to completely separate the fine suspended solids, affecting the environmental protection of sewage recycling or discharge. Some equipment with added filtration structures can only intercept large particles of impurities due to the single filtration method, and cannot effectively capture scum and flocculated fine particles, resulting in insufficient separation purity. Secondly, the separation components are prone to clogging and are inconvenient to maintain. Impurities in the sewage can easily adhere to the surface of the filter or leakage components, which can cause pore blockage after long-term use, resulting in poor sewage flow. Frequent shutdowns for disassembly and cleaning are required, which seriously reduces the continuity of cleaning operations. At the same time, the sewage tank's sealing structure is poorly designed, and sewage leakage is likely to occur during disassembly and cleaning. Furthermore, the disassembly and assembly process of the internal filter components and water storage components is cumbersome, which increases the maintenance difficulty for users. Third, the structural design is redundant and lacks functionality. In order to achieve functions such as stirring and filtering, some equipment has added multiple independent drive mechanisms, which not only occupy the limited internal space of the floor scrubber and violate the portable design concept of handheld equipment, but also increase energy consumption. In addition, after the equipment stops working, the filtering, transmission and other components cannot be automatically reset and need to be manually adjusted before the next use, which is not convenient to operate. At the same time, the sewage diversion lacks a precise guiding structure, and the sewage is unevenly distributed when entering the separation area, which further affects the separation efficiency. Fourth, there is a lack of collaborative operation mechanisms. The existing equipment's filtration, stirring, and anti-clogging functions are independent of each other and fail to form a linkage and synergy. For example, the stirring mechanism can only agitate the sewage and cannot work with the filtration components to improve the impurity interception effect. The anti-clogging structure also does not operate synchronously with the separation process, resulting in low overall separation efficiency and making it difficult to meet users' needs for efficient and convenient cleaning equipment. Summary of the Invention

A first transmission rod is fixedly mounted inside each of the two second bevel gears. The ends of the two first transmission rods that are far apart from each other pass through the T-shaped plate and extend to the outside.

[0007] Preferably, the drive assembly further includes two third bevel gears, which are respectively fixedly installed at the ends of the two first transmission rods that are far apart from each other. A fourth bevel gear is fixedly installed at the top of each of the two second transmission rods, and the two fourth bevel gears mesh with the two third bevel gears respectively.

[0008] Preferably, the top surface of the T-shaped plate has two sliding grooves arranged diagonally, and the same cover plate is slidably installed between the two sliding grooves. The cover plate is located above the flow channel, and the inner side wall of the cover plate is movably connected to the outer side wall of the mounting rod.

[0009] Preferably, a spiral filter screen is fixedly installed on the outer wall of the mounting rod. The spiral filter screen is wound around the mounting rod. Multiple stirring teeth are fixedly installed on the outer wall of the spiral filter screen. The multiple stirring teeth are arranged in a linear pattern and are all hollow. An air jet head is fixedly installed at one end of each of the multiple stirring teeth. A small air pump is fixedly installed inside each of the multiple stirring teeth. One end of the output port of each of the multiple small air pumps is fixedly connected to one side of the corresponding air jet head.

[0010] Preferably, a threaded sleeve is threaded onto the outer wall of the lead screw, and scrapers are fixedly installed on both sides of the threaded sleeve, with the outer walls of the two scrapers contacting one side of the corresponding leakage plate.

[0011] Preferably, an opening groove is provided on one side of the storage box, the opening groove is connected to the water outlet of the handheld floor scrubber body and the storage box, and a ramp guide plate is fixedly installed in the opening groove, the ramp angle of the ramp guide plate is adapted to the spiral angle of the spiral filter screen.

[0012] Preferably, the outer wall of the rotating rod is provided with a torsion spring, the bottom end of the torsion spring is fixedly connected to the inner bottom surface of the flow groove, and the top end of the torsion spring is fixedly connected to the outer wall of the rotating rod.

[0013] Preferably, an arc-shaped baffle is rotatably installed on the other side of the storage box. The arc-shaped baffle matches the storage slot. A retaining sleeve is fixedly installed on one side of the arc-shaped baffle. A limiting hole is opened on the outer wall of the storage box at a position corresponding to the retaining sleeve. The same insert rod is movably connected between the retaining sleeve and the limiting hole. A return spring is provided on the outer wall of the insert rod.

[0014] Preferably, a sealing strip is provided at the position where the arc-shaped baffle contacts the storage tank.

[0015] Compared with the prior art, the present invention has the following beneficial effects: Wastewater is precisely guided to the spiral filter area by the inclined guide plate. The spiral blades push the wastewater to achieve initial interception and collection of impurities. Combined with the aeration function of the hollow stirring teeth, the wastewater is disturbed to make it easier to capture scum and accelerate the flocculation of fine suspended solids. The subsequent drive component drives the arc stirring blades to stir the wastewater after initial filtration, which helps the wastewater flow to the seepage plate and avoids the deposition of suspended solids. The seepage plate then completes the secondary solid-liquid separation, forming a multi-stage separation system of filtration, aeration, stirring and seepage, which greatly improves the purity and comprehensiveness of solid-liquid separation. The rotation of the mounting rod synchronously drives the lead screw to rotate, which in turn drives the scraper to move up and down along the seepage plate through the thread transmission. This scrapes away the impurities attached to the plate in real time, preventing the seepage holes from becoming clogged at the source. This ensures that the seepage separation process is smooth and continuous, eliminating the need for frequent shutdowns for cleaning and effectively improving overall work efficiency. After the device stops working, the torsion spring can drive the rotating rod, the mounting rod and the spiral filter screen to automatically reverse and reset, so that it can be prepared for the next operation without manual adjustment. The cover can be opened and closed flexibly by sliding along the slide groove. When closed, it prevents sewage from splashing out, and when opened, it facilitates the maintenance of internal components. The arc-shaped baffle achieves sealing and quick disassembly through the insertion rod, the sleeve and the reset spring. With the movable water storage box, it can be easily removed to clean the sediment and intercept the scum, reducing the difficulty and frequency of maintenance. It adopts a single mounting rod linkage multi-component design, and realizes the synchronous movement of the mounting rod, arc-shaped mixing blade, scraper and spiral filter screen through the drive component. The structure has a high degree of integration, eliminating the need for additional multiple sets of drive mechanisms, saving internal space of the equipment, and meeting the portable design requirements of handheld floor scrubbers. At the same time, the sealing strip and return spring work together to ensure the sealing of the storage tank, prevent sewage leakage, and improve the user experience. The various components work together efficiently, with seamless integration of functions such as aeration disturbance, stirring boost, filtration interception, leakage separation, anti-clogging scraping, and automatic reset. This reduces energy consumption during wastewater treatment, prevents single component failures from affecting overall operation, and extends the equipment's service life. Meanwhile, the separated clean water is temporarily stored in a water storage box for easy subsequent treatment or recycling, making it more energy-efficient and environmentally friendly.

Detailed Implementation

[0018] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0019] Please see Figures 1-9 This invention provides a handheld floor scrubber with an integrated wastewater tank solid-liquid separation device, comprising: The handheld floor scrubber body 1 has a slot on one side of its top, into which a storage box 2 is installed. The storage box 2 is inserted into the slot, and a storage groove 4 is formed inside the storage box 2. A T-shaped plate 12 is fixedly installed inside the storage groove 4, and the bottom surface of the T-shaped plate 12 is fixedly connected to the inner bottom surface of the storage groove 4. Water storage boxes 16 are set on both sides of the T-shaped plate 12, and both water storage boxes 16 are movably fitted into the storage groove 4. Two second transmission rods 22 are rotatably installed on the inner bottom surface of the storage groove 4, and the two second transmission rods 22 are located on both sides of the T-shaped plate 12. Multiple arc-shaped stirring blades 23 are fixedly installed on the outer walls of the two second transmission rods 22. A flow channel 13 is provided. Inside the T-shaped plate 12, a flow channel 13 passes through the T-shaped plate 12 and is connected to the outside. Leakage plates are fixedly installed on both sides of the inside of the flow channel 13, and both leakage plates are connected to the inside of the storage tank 4. An installation rod 7 is installed inside the flow channel 13. The top end of the installation rod 7 is rotatably connected to the top surface of the storage tank 4. A lead screw 26 is fixedly installed at the bottom end of the installation rod 7, and a rotating rod 27 is fixedly installed at the bottom end of the lead screw 26. The bottom end of the rotating rod 27 is rotatably connected to the bottom surface of the inside of the flow channel 13. A drive assembly is installed on the installation rod 7 and is used to drive the two second transmission rods 22 to rotate. Wastewater generated during the floor scrubber operation is discharged from the outlet of the handheld floor scrubber body 1 and then passes through the storage tank. 2. The opening trough 5 on one side leads into the device. The inclined guide plate 6 inside the opening trough 5, due to its angle matching the spiral filter screen 8, can accurately guide the sewage to the spiral filter screen 8 area in the storage tank 4. At this time, the mounting rod 7 drives the spiral filter screen 8 to rotate synchronously. Utilizing the pushing action of the spiral blades, it intercepts and directionally collects the scum and suspended solids in the sewage. Simultaneously, the hollow stirring teeth 9 arranged linearly on the outer wall of the mounting rod 7 rotate synchronously with the filter screen, and the small air pump 10 inside it starts, aerating the sewage through the jet nozzle 11. This not only disturbs the sewage, making it easier for the scum to be intercepted by the spiral filter screen, but also accelerates the flocculation of fine suspended solids in the sewage, improving the subsequent separation effect. The rotation of 7 synchronously drives the first bevel gear 17 fixed on it to rotate. The first bevel gear 17 meshes with the second bevel gears 18 on both sides of the flow channel 13, driving the two first transmission rods 19 to rotate. The third bevel gear 20 at the end of the first transmission rod 19 meshes with the fourth bevel gear 21 at the top of the second transmission rod 22, thereby driving the two second transmission rods 22 and the arc-shaped stirring blades 23 on the rods to rotate. The arc-shaped stirring blades 23 rotate in the water storage box 16 area on both sides of the T-shaped plate 12, stirring the sewage after preliminary filtration by the spiral filter screen, accelerating the flow of sewage to the seepage plates on both sides of the flow channel 13, and at the same time preventing the sewage in the water storage box 16 from settling and causing suspended solids to settle, providing power assistance for subsequent seepage separation.After stirring, the wastewater undergoes secondary solid-liquid separation through the permeation of the permeation plate. The filtered clear water is temporarily stored in the storage box 16, while a small amount of unpermeated solid impurities remain on the surface of the permeation plate. During this process, the rotation of the mounting rod 7 synchronously drives the bottom screw 26 to rotate. The screw 26 and the threaded sleeve 24 on the outer wall form a threaded transmission, causing the threaded sleeve 24 to move up and down along the screw 26. This, in turn, drives the scrapers 25 on both sides to move synchronously. The scrapers 25 are in close contact with the surface of the permeation plate, which can scrape and remove the impurities attached to the permeation plate in real time, effectively preventing the permeation holes from becoming blocked and ensuring the continuity of permeation separation. This achieves full linkage of filtration, permeation, and anti-blocking. After the device stops working, the rotating rod 27 rotates outward. The torsion spring 28 on the side wall releases elastic potential energy, causing the rotating rod 27, mounting rod 7, and spiral filter screen 8 to rotate in the opposite direction and return to their initial working position, preparing for the next operation. The cover plate 15 on the top of the storage tank 4 can slide open and close along the slide groove 14 of the T-shaped plate 12. When closed, it prevents sewage from splashing out, and when open, it facilitates maintenance of the internal components of the flow channel 13. The arc-shaped baffle 3 on the other side of the storage tank 2 is sealed and fixed by the sleeve 29, the insert rod 30, and the return spring 31. The sealing strip ensures the airtightness of the storage tank 4. When it is necessary to clean the scum and maintain the water storage box 16, the arc-shaped baffle 3 can be opened by pulling out the insert rod 30, making it easy to remove the water storage box 16 to clean the sediment and intercepted scum.

[0020] This invention provides a handheld floor scrubber with an integrated wastewater tank solid-liquid separation device, which, in addition to the above-mentioned technical solution, also has the following technical features.

[0021] The drive assembly includes a first bevel gear 17, which is fixedly mounted on the outer side wall of the mounting rod 7. Two second bevel gears 18 are rotatably mounted on both sides of the inside of the flow groove 13. The two second bevel gears 18 are located on both sides of the first bevel gear 17. A first transmission rod 19 is fixedly mounted inside each of the two second bevel gears 18. The ends of the two first transmission rods 19 that are far apart from each other pass through the T-shaped plate 12 and extend to the outside.

[0022] The rotation of the mounting rod 7 synchronously drives the first bevel gear 17 fixed on it to rotate. The first bevel gear 17 meshes with the second bevel gears 18 on both sides of the flow channel 13, driving the two first transmission rods 19 to rotate. The third bevel gear 20 at the end of the first transmission rod 19 meshes with the fourth bevel gear 21 at the top of the second transmission rod 22, thereby driving the two second transmission rods 22 and the arc-shaped stirring blades 23 on the rods to rotate. The arc-shaped stirring blades 23 rotate in the water storage box 16 area on both sides of the T-shaped plate 12, stirring the sewage after preliminary filtration by the spiral filter screen, accelerating the flow of sewage to the seepage plates on both sides of the flow channel 13, and at the same time preventing the sewage in the water storage box 16 from settling and causing suspended solids to settle, thus providing power assistance for subsequent seepage separation.

[0023] This invention provides a handheld floor scrubber with an integrated wastewater tank solid-liquid separation device, which, in addition to the above-mentioned technical solution, also has the following technical features.

[0024] The drive assembly also includes two third bevel gears 20, which are fixedly installed at opposite ends of the two first transmission rods 19. A fourth bevel gear 21 is fixedly installed at the top of each of the two second transmission rods 22, and the two fourth bevel gears 21 mesh with the two third bevel gears 20 respectively.

[0025] When the first transmission rod 19 rotates, the third bevel gear 20 at its end rotates synchronously. Since the third bevel gear 20 meshes with the fourth bevel gear 21, this meshing transmission causes the fourth bevel gear 21 to rotate, which in turn drives the second transmission rod 22, which is fixedly connected to it, to rotate. The rotation of the second transmission rod 22 is stable and continuous; its speed and direction of rotation are precisely controlled by the first transmission rod 19 through the meshing of the bevel gears.

[0026] This invention provides a handheld floor scrubber with an integrated wastewater tank solid-liquid separation device, which, in addition to the above-mentioned technical solution, also has the following technical features.

[0027] The top surface of the T-shaped plate 12 has two sliding grooves 14, which are arranged diagonally. The same cover plate 15 is slidably installed between the two sliding grooves 14. The cover plate 15 is located above the flow channel 13, and the inner side wall of the cover plate 15 is movably connected to the outer side wall of the mounting rod 7.

[0028] Since the cover plate 15 is movably mounted on the mounting rod 7, when the mounting rod 7 rotates, although the cover plate 15 also rotates synchronously, it only moves between the two sliding grooves 14. When the rotation angle of the mounting rod 7 exceeds the limited position of the sliding groove 14, the cover plate 15 stops moving, exposing the flow channel 13. When the mounting rod 7 rotates in the opposite direction, the cover plate 15 moves in the opposite direction along the sliding groove 14 until it covers the flow channel 13 again. This design allows the opening and closing of the flow channel 13 to be flexibly controlled according to the rotation of the mounting rod 7. When it is necessary to allow sewage or other substances to pass through the flow channel 13, simply rotate the mounting rod 7 to the appropriate angle to move the cover plate 15 and expose the flow channel 13. When it is not necessary to allow flow, rotating the mounting rod 7 in the opposite direction will allow the cover plate 15 to close the flow channel 13 again, effectively preventing sewage leakage or unnecessary flow.

[0029] This invention provides a handheld floor scrubber with an integrated wastewater tank solid-liquid separation device, which, in addition to the above-mentioned technical solution, also has the following technical features.

[0030] A spiral filter screen 8 is fixedly installed on the outer wall of the mounting rod 7. The spiral filter screen 8 is wound around the mounting rod 7. Multiple stirring teeth 9 are fixedly installed on the outer wall of the spiral filter screen 8. The multiple stirring teeth 9 are arranged in a linear shape and are all hollow. A jet head 11 is fixedly installed at one end of each of the multiple stirring teeth 9. A small air pump 10 is fixedly installed inside each of the multiple stirring teeth 9. One end of the output port of each of the multiple small air pumps 10 is fixedly connected to one side of the corresponding jet head 11.

[0031] Among them, the hollow stirring teeth 9 arranged in a linear pattern on the outer wall of the mounting rod 7 rotate synchronously with the filter screen. The small air pump 10 inside it starts and aerates the sewage through the jet nozzle 11. On the one hand, it can disturb the sewage, making it easier for the scum to be intercepted by the spiral filter screen. On the other hand, it can accelerate the flocculation of fine suspended solids in the sewage and improve the subsequent separation effect.

[0032] This invention provides a handheld floor scrubber with an integrated wastewater tank solid-liquid separation device, which, in addition to the above-mentioned technical solution, also has the following technical features.

[0033] A threaded sleeve 24 is threaded onto the outer wall of the lead screw 26. Scrapers 25 are fixedly installed on both sides of the threaded sleeve 24, and the outer walls of the two scrapers 25 are in contact with one side of the corresponding leakage plate.

[0034] The installation rod 7 rotates synchronously, driving the lead screw 26 at the bottom to rotate. The lead screw 26 and the threaded sleeve 24 on the outer wall form a threaded transmission, causing the threaded sleeve 24 to move up and down along the lead screw 26, which in turn drives the scrapers 25 on both sides to move synchronously. The scrapers 25 are in close contact with the surface of the seepage plate, which can scrape and remove the impurities attached to the seepage plate in real time, effectively preventing the seepage holes from being blocked, ensuring the continuity of seepage separation, and realizing the full linkage of filtration, seepage and anti-blockage.

[0035] This invention provides a handheld floor scrubber with an integrated wastewater tank solid-liquid separation device, which, in addition to the above-mentioned technical solution, also has the following technical features.

[0036] An opening slot 5 is provided on one side of the storage tank 2. The opening slot 5 is connected to the water outlet of the handheld floor scrubber body 1 and the storage tank 4. A ramp guide plate 6 is fixedly installed in the opening slot 5. The ramp angle of the ramp guide plate 6 is matched with the spiral angle of the spiral filter screen 8.

[0037] The wastewater flows out from the outlet of the handheld floor scrubber 1 and enters the device through the opening slot 5 on one side of the storage tank 2. The inclined guide plate 6 in the opening slot 5 is adapted to the spiral filter screen 8 at an angle, which can accurately guide the wastewater to the spiral filter screen 8 area in the storage tank 4. At this time, the mounting rod 7 drives the spiral filter screen 8 to rotate synchronously. The spiral blades push to intercept and collect the scum and suspended solids in the wastewater.

[0038] This invention provides a handheld floor scrubber with an integrated wastewater tank solid-liquid separation device, which, in addition to the above-mentioned technical solution, also has the following technical features.

[0039] A torsion spring 28 is provided on the outer wall of the rotating rod 27. The bottom end of the torsion spring 28 is fixedly connected to the inner bottom surface of the flow groove 13, and the top end of the torsion spring 28 is fixedly connected to the outer wall of the rotating rod 27.

[0040] When the device stops working, the torsion spring 28 on the outer wall of the rotating rod 27 releases its elastic potential energy, causing the rotating rod 27, the mounting rod 7 and the spiral filter screen 8 to rotate in the opposite direction and return to their initial working positions, preparing for the next operation.

[0041] This invention provides a handheld floor scrubber with an integrated wastewater tank solid-liquid separation device, which, in addition to the above-mentioned technical solution, also has the following technical features.

[0042] An arc-shaped baffle 3 is rotatably installed on the other side of the storage box 2. The arc-shaped baffle 3 matches the storage slot 4. A sleeve 29 is fixedly installed on one side of the arc-shaped baffle 3. A limit hole is opened on the outer wall of the storage box 2 at the position corresponding to the sleeve 29. The same insertion rod 30 is movably connected between the sleeve 29 and the limit hole. A return spring 31 is provided on the outer wall of the insertion rod 30.

[0043] When it is necessary to clean the scum and suspended matter trapped in the storage tank 4, the insertion rod 30 can be pulled outward to make the insertion rod 30 overcome the elastic force of the return spring 31 and be pulled out from the limiting hole and the sleeve 29. At this time, the arc-shaped baffle 3 is no longer fixed. Since the arc-shaped baffle 3 is rotatably installed on the other side of the storage box 2, the arc-shaped baffle 3 can be rotated outward to open, thereby facilitating the cleaning operation of the storage tank 4.

[0044] This invention provides a handheld floor scrubber with an integrated wastewater tank solid-liquid separation device, which, in addition to the above-mentioned technical solution, also has the following technical features.

[0045] A sealing strip is provided at the position where the arc-shaped baffle 3 contacts the storage tank 4.

[0046] This sealing strip has good elasticity and sealing performance, which can effectively prevent sewage and impurities from leaking out of the storage tank 4. When the arc-shaped baffle 3 is closed, the sealing strip will be squeezed to a certain extent, thus tightly adhering to the contact surface between the arc-shaped baffle 3 and the storage tank 4, forming a reliable sealing structure.

[0047] Working principle: Wastewater generated during floor scrubbing is discharged from the outlet of the handheld floor scrubbing machine body 1 and enters the device through the opening trough 5 on one side of the storage tank 2. The inclined guide plate 6 in the opening trough 5 is adapted to the spiral filter screen 8 at an angle, which can accurately guide the wastewater to the spiral filter screen 8 area in the storage tank 4. At this time, the mounting rod 7 drives the spiral filter screen 8 to rotate synchronously. The spiral blades push to intercept and collect the scum and suspended solids in the wastewater. At the same time, the hollow stirring teeth 9 arranged linearly on the outer wall of the mounting rod 7 rotate synchronously with the filter screen. The small air pump 10 inside is started and aeration is introduced into the wastewater through the jet nozzle 11. On the one hand, the wastewater is disturbed, making it easier for the scum to be intercepted by the spiral filter screen. On the other hand, it accelerates the flocculation of fine suspended solids in the wastewater and improves the subsequent separation effect. The rotation of the mounting rod 7 synchronously drives the first bevel gear 17 fixed on it to rotate. The first bevel gear 17 meshes with the second bevel gears 18 on both sides of the flow channel 13, driving the two first transmission rods 19 to rotate. The third bevel gear 20 at the end of the first transmission rod 19 meshes with the fourth bevel gear 21 at the top of the second transmission rod 22, thereby driving the two second transmission rods 22 and the arc-shaped stirring blades 23 on the rods to rotate. The arc-shaped stirring blades 23 rotate in the water storage box 16 area on both sides of the T-shaped plate 12, stirring the sewage after preliminary filtration by the spiral filter screen, accelerating the flow of sewage to the seepage plates on both sides of the flow channel 13, and at the same time preventing the sewage in the water storage box 16 from settling and causing suspended solids to settle, providing power assistance for subsequent seepage separation. After being stirred, the wastewater undergoes a secondary solid-liquid separation through the permeation of the permeation plate. The filtered clean water is temporarily stored in the water storage box 16, while a small amount of solid impurities that have not permeated remain on the surface of the permeation plate. During this process, the installation rod 7 rotates synchronously, driving the lead screw 26 at the bottom to rotate as well. The lead screw 26 and the threaded sleeve 24 on the outer wall form a threaded transmission, causing the threaded sleeve 24 to move up and down along the lead screw 26. This, in turn, drives the scrapers 25 on both sides to move synchronously. The scrapers 25 are in close contact with the surface of the permeation plate, which can scrape and remove the impurities attached to the permeation plate in real time, effectively preventing the permeation holes from becoming blocked, ensuring the continuity of permeation separation, and realizing the full linkage of filtration, permeation, and anti-blockage. After the device stops working, the torsion spring 28 on the outer wall of the rotating rod 27 releases its elastic potential energy, causing the rotating rod 27, the mounting rod 7, and the spiral filter screen 8 to rotate in the opposite direction and return to their initial working positions, preparing for the next operation. The cover plate 15 on the top of the storage tank 4 can slide open and close along the slide groove 14 of the T-shaped plate 12. When closed, it can prevent sewage from splashing out, and when open, it is convenient to maintain the internal components of the flow channel 13. The arc-shaped baffle 3 on the other side of the storage tank 2 is sealed and fixed by the sleeve 29, the insertion rod 30, and the return spring 31. The sealing strip ensures the airtightness of the storage tank 4. When it is necessary to clean the scum and maintain the water storage box 16, the insertion rod 30 can be pulled out to open the arc-shaped baffle 3, and the water storage box 16 can be easily removed to clean the sediment and intercepted scum.
