Description

Technical Field

[0001] The present invention relates to the technical field of wastewater treatment, in particular to a low-cost micro-polluted water supply treatment device. Background Art

[0002] In the fields of environmental protection and water resource management, raw water treatment and purification processes are crucial for ensuring water resource safety and sustainable utilization. Raw water typically refers to untreated natural water bodies, including river, lake, and well water. It contains a variety of impurities, such as suspended solids, microorganisms, organic matter, inorganic salts, heavy metal ions, and possible pathogens. These impurities not only degrade water quality but also pose a threat to human health. Therefore, the development of efficient raw water treatment and purification technologies is crucial.

[0003] Currently, conventional treatment methods for water bodies with varying degrees of pollution include testing raw water quality to assess the degree of contamination and select appropriate purification processes accordingly. For moderately and heavily polluted water, advanced treatment is typically performed using complex water purification systems within sewage treatment plants. However, for raw water with lower levels of contamination (i.e., low-pollution water), even though its contamination does not meet the standards for direct use, returning it to sewage treatment plants for treatment results in a waste of resources. This is because traditional sewage treatment systems are complex and designed for highly polluted water, and are clearly not effectively adapted to the treatment needs of low-pollution water.

[0004] Furthermore, existing technologies lack specialized purification solutions for low-pollution water, preventing its direct use and preventing optimal resource utilization within existing sewage treatment systems. This hinders the efficient management of low-pollution water resources. Therefore, developing an efficient, cost-effective, and applicable purification technology for low-pollution water has become a key challenge that needs to be addressed. Summary of the Invention

[0016] The technical solution adopted by the present invention can achieve the following beneficial effects: The present invention is connected to an external slightly polluted water source through a water pipe, and the external slightly polluted water source is discharged into the upper area of ​​the first group of filter boxes through the water pipe. Under the action of the filter element, impurities in the slightly polluted water can be blocked by the filtering effect of the filter element, thereby purifying the water after passing through the filter element, and the purified water flows directly to the water storage tank through the lower area for storage.

[0017] After long-term use, the upper surface of the filter element in the first filter box may be attached with a large amount of residual pollutants due to the long-term blocking of slightly polluted water, thereby blocking the upper surface of the filter element, making it impossible for the slightly polluted water to pass through the upper area and enter the lower area normally. At this time, it is necessary to treat the pollutants attached to the upper surface of the filter element. During treatment, in order not to affect the normal purification of slightly polluted water, the second filter mechanism can be used to perform filtering instead, while treating the pollutants on the surface of the filter element in the first filter mechanism. The specific operation is as follows: The isolation and cleaning mechanism is activated so that a portion of the isolation and cleaning mechanism enters the upper area of ​​the first group, forming a first cleaning gap with the upper surface of the first group of filters. During this process, the isolation and cleaning mechanism drives the opening and closing mechanism to be in an open state, allowing the slightly contaminated water in the upper area of ​​the first group located above the first cleaning gap to enter the upper area of ​​the second group through the transverse connecting pipe, and be filtered normally by the filter elements in the second group. At this time, the separated first cleaning gap becomes a separate isolation space, and the pollutants attached to the upper surface of the filter element can be cleaned by the isolation and cleaning mechanism. After cleaning, the first group of filter mechanisms can be put into normal use, but the second group of filter mechanisms is already in use. Therefore, you can wait until the second group of filter mechanisms can no longer filter the slightly contaminated water normally, then switch back to the first group of filter mechanisms and clean the second group of filter mechanisms at the same time.

[0018] With this setup, slightly contaminated water can be filtered using the aforementioned method, eliminating the need for sewage treatment plants to expend significant resources purifying the water. This device can be used to treat the water individually, significantly reducing treatment costs. Furthermore, the device can be reused repeatedly. In the event of a filtration failure, uninterrupted filtration can be achieved by switching between the two filter mechanisms, avoiding the significant energy consumption associated with pausing and restarting the device, significantly reducing treatment costs.

DETAILED DESCRIPTION

[0022] To make the objectives, technical solutions, and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other implementations obtained by those of ordinary skill in the art without inventive effort are within the scope of protection of the present invention.

[0023] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0024] The following is combined with Figures 1 to 12 , a low-cost slightly polluted water supply treatment device provided by this application is described in detail through specific embodiments and application scenarios.

[0025] Please refer to Figures 1 to 3 A low-cost slightly polluted water supply treatment device includes a water pipe 100, a filtering mechanism 200 and a water storage tank 300. One end of the water pipe 100 is connected to an external slightly polluted water source, and the other end is connected to the filtering mechanism 200. The filtering mechanism 200 is used to filter pollutants in the slightly polluted water. The water storage tank 300 is connected to the filtering mechanism 200 and is used to store filtered water.

[0026] Exemplarily, the filter mechanism 200 includes a filter box 210 and a filter element 220. The filter element 220 divides the filter box 210 into an upper area 211 and a lower area 212. The upper area 211 is higher than the lower area 212. Two sets of filter mechanisms 200 are arranged side by side. The upper areas 211 of the two sets of filter mechanisms 200 are connected via a transverse connecting pipe 600. The upper area 211 in the first set of filter mechanisms 200 is connected to the water supply pipe 100, and the lower areas 212 in the two sets of filter mechanisms 200 are connected to the water storage tank 300 via a drainage pipe. Furthermore, the filter material of the filter element 220 can be selected from at least one of sand filter material, porous medium material, fiber filter material, membrane material, granular filter material, and other specialized materials. Among these filter materials, sand filter material can be selected from manganese sand, which can be used to remove metal ions such as iron and manganese from water. The porous medium material can be selected from activated carbon, which has extremely high adsorption capacity and is suitable for removing organic pollutants, odors, color, etc. Fiber filter media options include polypropylene and glass fibers. Polypropylene fiber is used for deep filtration and effectively removes fine suspended matter and grease. Glass fiber is suitable for filtration in high-temperature environments and is commonly used in industrial wastewater treatment. Membrane materials include microfiltration, ultrafiltration, and reverse osmosis membranes. Microfiltration membranes remove bacteria, large organic molecules, and suspended solids. Ultrafiltration membranes remove bacteria, viruses, and most organic matter. Reverse osmosis membranes are suitable for removing dissolved salts, heavy metals, and small organic molecules and are widely used for deep water purification. Garnet sand is an option for granular filter media. Its high density and excellent filtration properties make it suitable for removing heavy metals and suspended solids.

[0027] Exemplarily, the device also includes an isolation and cleaning mechanism 400 and an opening and closing mechanism 500. The isolation and cleaning mechanism 400 is arranged between the two groups of filtering mechanisms 200. The isolation and cleaning mechanism 400 has a switchable first state and a second state. When the isolation and cleaning mechanism 400 is switched to the first state, a portion of the isolation and cleaning mechanism 400 and the upper surface of the first group of filter elements 220 form a first cleaning gap in the first group upper area 211. At this time, the isolation and cleaning mechanism 400 in the first state can clean the pollutants attached to the upper surface of the first group of filter elements 220, so that most of the pollutants on the upper surface of the first group of filter elements 220 located in the first cleaning gap are detached; when the isolation and cleaning mechanism 400 is switched to the second state, a portion of the isolation and cleaning mechanism 400 and the upper surface of the second group of filter elements 220 form a second cleaning gap in the second group upper area 211. At this time, the isolation and cleaning mechanism 400 in the second state can clean the pollutants attached to the upper surface of the second group of filter elements 220, so that most of the pollutants on the upper surface of the second group of filter elements 220 located in the second cleaning gap are detached.

[0028] Exemplarily, the opening and closing mechanism 500 is provided in the transverse connecting pipe 600, which is located in the first group of upper areas 211 and above the first cleaning gap. The opening and closing mechanism 500 is used to control the connection and closing of the transverse connecting pipe 600, wherein, when the isolation cleaning mechanism 400 switches from the second state to the first state, the opening and closing mechanism 500 gradually switches to the open state under the action of the isolation cleaning mechanism 400, so that the two groups of upper areas 211 are connected; when the isolation cleaning mechanism 400 switches from the first state to the second state, the opening and closing mechanism 500 gradually switches to the closed state under the action of the isolation cleaning mechanism 400, so that the two groups of upper areas 211 are separated.

[0029] On this basis, the external slightly polluted water source is connected through the water pipe 100, and the external slightly polluted water source is discharged into the upper area 211 of the first group of filter box 210 through the water pipe 100. Under the action of the filter element 220, the impurities in the slightly polluted water can be blocked by the filtering effect of the filter element 220, thereby allowing the water after passing through the filter element 220 to be purified, and the purified water flows directly to the water storage tank 300 through the lower area 212 for storage.

[0030] After prolonged use, the upper surface of the filter element 220 in the first filter box 210 may be clogged with a large amount of residual contaminants due to its long-term blocking of slightly polluted water. This may block the upper surface of the filter element 220, preventing the slightly polluted water from passing through the upper area 211 and entering the lower area 212. At this point, it is necessary to treat the contaminants attached to the upper surface of the filter element 220. During treatment, in order not to affect the normal purification of the slightly polluted water, the second filter mechanism 200 can be used to perform the filtration while treating the contaminants on the surface of the filter element 220 in the first filter mechanism 200. The specific operation is as follows: The isolation and cleaning mechanism 400 is activated, allowing a portion of it to enter the upper region 211 of the first filter group, forming a first cleaning gap with the upper surface of the first filter element 220. During this process, the isolation and cleaning mechanism 400 drives the opening and closing mechanism 500 to the open state, allowing the slightly contaminated water in the first upper region 211 above the first cleaning gap to enter the second upper region 211 through the transverse connecting pipe 600, and then be filtered normally by the filter element 220 in the second filter group. At this point, the separated first cleaning gap becomes a separate isolation space, and the isolation and cleaning mechanism 400 can now clean the contaminants attached to the upper surface of the filter element 220. After cleaning is completed, the first filter mechanism 200 can be put into normal use. However, the second filter mechanism 200 is already in use. Therefore, it is possible to wait until the second filter mechanism 200 is no longer able to filter the slightly contaminated water normally before switching back to the first filter mechanism 200 and cleaning the second filter mechanism 200 at the same time.

[0031] With this arrangement, slightly contaminated water can be filtered using the aforementioned method, eliminating the need for sewage treatment plants to expend significant resources purifying the slightly contaminated water. The aforementioned device can be used to treat the slightly contaminated water individually, significantly reducing treatment costs. Furthermore, the aforementioned device can be reused repeatedly. In the event of a filtration failure, uninterrupted filtration can be achieved by switching between the two sets of filtration mechanisms 200, avoiding the significant energy consumption associated with pausing and restarting the device, thereby significantly reducing treatment costs.

[0032] In some embodiments, Figure 2 、 Figure 3 as well as Figure 4As shown, the isolation and cleaning mechanism 400 includes a drive component 410 and a partition component 420. The drive component 410 is installed between the two groups of filtering mechanisms 200. Two groups of partition components 420 are movably provided on the drive component 410. Under the driving action of the drive component 410, one of the two groups of partition components 420 moves to the first group upper area 211 to form a first cleaning gap while the other can be separated from the second group upper area 211; or, one of them separates from the first group upper area 211 while the other moves to the second group upper area 211 to form a second cleaning gap.

[0033] Exemplarily, the drive assembly 410 includes a fixed base 411, a motor 412, a guide rod 413, a threaded sleeve 414, and a threaded rod 415. The fixed base 411 is hollow and, exemplarily, is mounted on the upper wall of the water tank 300. Furthermore, the motor 412 is mounted within the fixed base 411, and the threaded rod 415 is coaxially connected to the output shaft of the motor 412. The guide rod 413 and the threaded rod 415 are both vertically and parallelly mounted on the fixed base 411. The threaded rod 415 includes a first threaded segment 4151 and a second threaded segment 4152 coaxially connected, the first threaded segment 4151 and the second threaded segment 4152 being separated by a limiting portion. A threaded sleeve 414 is provided on each of the first threaded segment 4151 and the second threaded segment 4152, and each threaded sleeve 414 is connected to a corresponding set of partition assemblies 420. For example, the motor 412 is a servo motor, which can achieve reverse rotation after forward rotation, and has a high degree of adaptability to the present device.

[0034] At the same time, combined Figure 5 as well as Figure 6 A guide hole 414 a is formed through the threaded sleeve 414 , and the threaded sleeve 414 slides in cooperation with the guide rod 413 through the guide hole 414 a .

[0035] Furthermore, when the threaded rod 415 rotates, the two threaded sleeves 414 move vertically upward or downward synchronously, wherein, when the two threaded sleeves 414 move vertically upward synchronously, the threaded sleeve 414 located in the first threaded segment 4151 drives the corresponding partition assembly 420 to disengage from the first group of upper areas 211, and the threaded sleeve 414 located in the second threaded segment 4152 drives the corresponding partition assembly 420 to move into the second group of upper areas 211 to form a second cleaning gap; when the two threaded sleeves 414 move vertically downward synchronously, the threaded sleeve 414 located in the first threaded segment 4151 drives the corresponding partition assembly 420 to move into the first group of upper areas 211 to form a first cleaning gap, and the threaded sleeve 414 located in the second threaded segment 4152 drives the corresponding partition assembly 420 to disengage from the second group of upper areas 211.

[0036] On this basis, after starting the motor 412, the motor 412 drives the threaded rod 415 to rotate. Due to the sliding limit cooperation between the guide rod 413 and the guide hole 414a on the threaded sleeve 414, the threaded sleeve 414 does not rotate on its own, thereby driving the threaded sleeve 414 to move in the length direction of the threaded rod 415. When the two sets of threaded sleeves 414 move vertically downward at the same time, the partition assembly 420 connected to the threaded sleeve 414 in the first threaded section 4151 can gradually enter the upper area 211 of the first group of filter boxes 210, so that the partition assembly 420 can form a first cleaning space in the upper area 211 of the first group of filter boxes 210, and also conveniently isolate the upper surface of the first group of filters 220 from the flow path of the slightly contaminated water currently circulating. At the same time, the barrier assembly 420, connected to the threaded sleeve 414 within the second threaded section 4152, gradually withdraws from the upper region 211 within the second filter box 210, allowing slightly contaminated water to flow normally from the upper region 211 of the first filter box through the transverse connecting pipe 600 into the upper region 211 of the second filter box. The water then flows from the lower region 212 of the second filter mechanism 200 to the water reservoir 300 for storage under the filtering action of the second filter element 220. When both threaded sleeves 414 move vertically upward simultaneously, the aforementioned process is reversed, and will not be further described here.

[0037] That is to say, by vertically moving the two threaded sleeves 414 upward or downward, the two groups of filtering mechanisms 200 can be switched, so that when a filtering failure occurs in one group of filtering mechanisms 200, the other group of filtering mechanisms 200 can filter synchronously without the need to pause the device, thereby improving the operational continuity of the equipment and reducing the large amount of electrical energy consumed by the equipment during the opening and closing process.

[0038] In some embodiments, Figure 4 、 Figure 5 、 Figure 7 as well as Figure 8As shown, the partition assembly 420 includes a silicone sealing membrane sleeve 421 and a partition rod 422, wherein the partition rods 422 are arranged in parallel in multiple groups, and adjacent partition rods 422 are relatively hingedly arranged, and the silicone sealing membrane sleeve 421 is sealed and covered on the periphery of the multiple partition rods 422; the outer wall of the filter box 210 is provided with a curved guide tube 700, and the curved guide tube 700 can be used for multiple partition rods 422 to slide inside, and the curved guide tube 700 includes a vertical pipe section 710, an arc-shaped pipe section 720 and a horizontal pipe section 730 that are connected in sequence, and a connecting bar hole 213 is opened on the side wall of the filter box 210, and the horizontal pipe section 730 is connected to the upper area 211 through the connecting bar hole 213. Furthermore, the sum of the diameter of the partition rods 422 and the thickness of the silicone sealing film sleeve 421 is equal to the width of the connecting rod hole 213, and the surface of the silicone sealing film sleeve 421 slides and seals against the inner wall of the connecting rod hole 213, thereby preventing leakage of slightly contaminated water within the upper region 211 to a certain extent. Exemplarily, the straight length of the plurality of partition rods 422 is greater than the length of the side groove 214, so that when the plurality of partition rods 422 partially enter the side groove 214 to fill the side groove 214 and form the first cleaning gap, the remaining portion of the plurality of partition rods 422 remains within the curved guide tube 700. This improves the sealing of the connecting rod hole 213 and prevents leakage of slightly contaminated water.

[0039] For example, a side groove 214 is horizontally opened on the inner side wall of the upper area 211 of the filter box 210. The side groove 214 and the connecting bar hole 213 are on the same horizontal plane. The side groove 214 is used to allow the end of the partition assembly 420 entering the upper area 211 to slide horizontally. For example, a vertical gap 711 is vertically opened on the side wall of the vertical pipe section 710, and a connecting rod 4141 is provided on the threaded sleeve 414. The connecting rod 4141 passes through the vertical gap 711 and is connected to the top or bottom end of the partition assembly 420. Under the pushing action of the threaded sleeve 414, the partition assembly 420 can gradually enter the upper area 211 along the curved guide tube 700 and the side groove 214 to form a first cleaning gap and a second cleaning gap; at the same time, under the pulling action of the threaded sleeve 414, the partition assembly 420 can gradually separate from the upper area 211 along the side groove 214 and the curved guide tube 700.

[0040] After being set up in this way, when the threaded sleeve 414 in the first threaded segment 4151 moves vertically downward, the corresponding connecting rod 4141 will also move vertically downward in the vertical gap 711, thereby pushing the partition assembly 420 corresponding to the first group of filter mechanisms 200 downward from top to bottom. Due to the guiding effect of the curved guide tube 700, the partition assembly 420 can gradually deflect from a vertical state to a horizontal state, and then the partition assembly 420 corresponding to the first group of filter mechanisms 200 partially extends horizontally into the side groove 214 in the first group upper area 211, so that under the continued push of the threaded sleeve 414 in the first threaded segment 4151, the part of the partition assembly 420 corresponding to the first group of filter mechanisms 200 is completely filled in the side groove 214, and finally the first cleaning gap is formed under the partition effect of the partition assembly 420. During this process, the barrier assemblies 420 corresponding to the second filter mechanism 200 are sequentially withdrawn from the side grooves 214 and the curved guide tube 700, causing the second cleaning gap to disappear as the corresponding barrier assemblies 420 gradually withdraw. This allows slightly contaminated water entering the upper area 211 of the second filter mechanism 200 through the transverse connecting tube 600 to pass normally through the second filter element 220 for filtration. When the threaded sleeve 414 in the first threaded section 4151 moves vertically upward, the operating principle is the opposite of the above process and will not be further described here.

[0041] In some embodiments, Figure 7 as well as Figure 8 As shown, adjacent ends of adjacent partition rods 422 are each provided with a lug 4221, and two adjacent lugs 4221 are each provided with a through-hole, into which a rotating rod 4222 is inserted, so that the two adjacent lugs 4221 can rotate relative to each other around the rotating rod 4222. For example, both ends of the rotating rod 4222 are provided with a stop block, which can prevent the rotating rod 4222 from being separated from the through-hole.

[0042] Exemplarily, both sides of the lugs 4221 are inclined surfaces, forming a rotational gap between two adjacent inclined surfaces. The width of the rotational gap gradually decreases from the side away from the rotational rod 4222 to the side closer to the rotational rod 4222 along the extension direction perpendicular to the rotational rod 4222. With this arrangement, the two lugs 4221 enable relative bending between two adjacent partition rods 422, allowing the multiple partition rods 422, which are hinged in sequence, to achieve corresponding changes in curvature when moving within the curved guide tube 700, while also enabling normal switching between vertical and horizontal positions. Furthermore, the rotational gap increases the relative bending angle between two adjacent partition rods 422, thereby improving the smoothness of movement of the multiple partition rods 422 within the curved guide tube 700 to a certain extent.

[0043] In some embodiments, combined Figure 2 、 Figure 4 、 Figure 9 as well as Figure 10 The isolation and cleaning mechanism 400 further includes a flushing assembly 430, which includes a backwash pump 431, a first tube 432, a second tube 433, a hose 434, a branch pipe 435, and a high-pressure nozzle 436. The pump inlet of the backwash pump 431 is connected to the water reservoir 300 via the first tube 432, and the second tube 433 is connected to the pump outlet of the backwash pump 431. The interior of the partition rod 422 is hollow, and the hose 434 sequentially passes through the plurality of partition rods 422, with one end of the hose 434 connected to the second tube 433. Exemplarily, the second tube 433 is an organ pipe, so that when the threaded sleeve 414 drives the partition assembly 420 to move vertically, it does not affect the normal transmission of water in the second tube 433.

[0044] Exemplarily, the branch pipe 435 is arranged inside the partition rod 422 along the length direction of the partition rod 422, and a plurality of high-pressure nozzles 436 are spaced apart on the branch pipe 435 along the length direction of the branch pipe 435, and a membrane hole corresponding to the nozzle end of the high-pressure nozzle 436 is reserved on the silicone sealing membrane sleeve 421; further, when the partition assembly 420 partially slides into the side groove 214, the high-pressure water column ejected from the nozzle of the high-pressure nozzle 436 can be sprayed onto the upper surface of the filter element 220 through the membrane hole. For example, the entire high-pressure nozzle 436 does not extend out of the partition rod 422, but a hole body connected to the hollow part inside the partition rod 422 is opened on the surface of the partition rod 422, and the high-pressure nozzle 436 is embedded in the hole body. At the same time, the outer periphery of the membrane hole is sealed and bonded to the outer periphery of the hole body. In this way, the entire partition assembly 420 can be prevented from being disturbed by the high-pressure nozzle 436 during movement and reducing the smoothness of movement. At the same time, the high-pressure nozzle 436 can also normally spray high-pressure water toward the upper surface of the filter element 220.

[0045] For example, among the multiple partition rods 422, only the partition rods 422 that can slide into the side groove 214 have the high-pressure nozzle 436, while the partition rods 422 that cannot slide into the side groove 214 do not have the high-pressure nozzle 436. Furthermore, when the threaded sleeve 414 in the first threaded section 4151 moves to the highest point, the partition rod 422 farthest from the threaded sleeve 414 is located in the connecting rod hole 213, thereby blocking the connecting rod hole 213.

[0046] On this basis, when a portion of the multiple partition rods 422 has been filled in the side groove 214 and a first cleaning gap has been formed, the high-pressure nozzles 436 on the partition rods 422 are all facing the upper surface of the filter element 220. At this time, the backwash pump 431 is started, and the water in the water tank 300 passes through the first tube body 432, the second tube body 433, the hose 434 and the branch pipe 435 in turn, and finally is sprayed out from the high-pressure nozzle 436 in the form of high-pressure water and acts on the upper surface of the filter element 220, so that the upper surface of the filter element 220 is washed down under the action of the high-pressure water column, thereby improving the cleaning effect of the upper surface of the filter element 220.

[0047] In some embodiments, combined Figure 3 、 Figure 4 、 Figure 11 as well as Figure 12 The opening and closing mechanism 500 includes a moving component 510 and a shielding component 520. The moving component 510 moves horizontally along the inner wall of the filter box 210 under the push of the partition component 420. The shielding component 520 is hinged on the moving component 510 and is used to shield the pipe opening of the transverse connecting pipe 600 located in the first group upper area 211.

[0048] At the same time, in the process of part of the partition component 420 entering the upper area 211 and moving horizontally along the side groove 214, part of the partition component 420 first pushes the movable component 510 horizontally away from the transverse connecting pipe 600, and then pushes the shielding component 520 to rotate to avoid the partition component 420; in the process of part of the partition component 420 moving horizontally along the side groove 214 and gradually leaving the upper area 211, the shielding component 520 and the movable component 510 gradually and automatically reset to the position of shielding the pipe opening of the transverse connecting pipe 600 located in the first group of upper areas 211.

[0049] Exemplarily, the moving assembly 510 includes a moving block 511 and a tension spring 512. A horizontal groove 215 for sliding of the moving block 511 is provided on the inner wall of the first group of filter boxes 210 and is located above the side groove 214. One end of the tension spring 512 is provided at the end of the horizontal groove 215, and the other end is connected to the moving block 511.

[0050] Exemplarily, the shielding assembly 520 includes a hinged rod 521 and a sealing shielding plate 522. The hinged rod 521 is hinged to the moving block 511 through a torsion spring 800. The sealing shielding plate 522 is provided at the lower end of the hinged rod 521 and is partially located on the moving path of the partition assembly 420 when it moves in the side groove 214. A limit bar 216 is provided on the inner side wall of the first group of filter boxes 210 and above the horizontal groove 215. The length of the limit bar 216 is less than the length of the horizontal groove 215. The upper end surface of the hinged rod 521 is flat and can be slidably fitted on the lower wall surface of the limit bar 216. In the embodiment, when the torsion spring 800 is in a natural state, the hinged rod 521 is in a vertical state and the upper end face of the hinged rod 521 is limited and fits against the lower wall face of the limiting strip 216, so as to prevent the hinged rod 521 from rotating when the partition assembly 420 moves in the side groove 214 and pushes the sealing baffle 522 to move horizontally; when the partition assembly 420 moves in the side groove 214, it pushes the sealing baffle 522 to move until the upper end face of the hinged rod 521 is separated from the limiting strip 216, and then the sealing baffle 522 rotates around the torsion spring 800 under the continued push of the partition assembly 420 and avoids the partition assembly 420.

[0051] On this basis, when the partition assembly 420 partially enters the side groove 214 through the curved guide tube 700 and moves horizontally within the side groove 214, the end of the partition assembly 420 will first abut against the sealing shield plate 522. At this time, because the top end of the hinge rod 521 is flat and slides in contact with the lower wall of the limit bar 216, the hinge rod 521 cannot rotate about the hinge point due to the restraining effect of the two. Therefore, the sealing shield plate 522 moves in a direction parallel to the length of the limit bar 216 under the pushing action of the partition assembly 420. During this process, the sealing shield plate 522 moves horizontally, thereby opening the pipe opening of the transverse connecting pipe 600 located in the upper area 211 of the first group of filter mechanisms 200. Then, as the partition assembly 420 continues to move in the side groove 214, since the length of the limit bar 216 is less than the length of the horizontal groove 215, after the moving block 511 moves to the position where the hinge rod 521 disengages from the limit bar 216 and the moving block 511 moves to the end of the horizontal groove 215, the top end of the hinge rod 521 is no longer restricted by the limit bar 216, and the moving block 511 cannot continue to move after moving to the end of the horizontal groove 215. At this time, the partition assembly 420 will push the sealing baffle 522 to rotate around the hinge point, so that the partition assembly 420 rotates to a position where it no longer blocks the movement of the partition assembly 420, that is, the sealing baffle 522 is forcibly pushed to rotate and leave the initial position through the partition assembly 420. At this time, the torsion spring 800 and the tension spring 512 are both in a state of storing elastic force.

[0052] When the partition component 420 needs to retreat from the side groove 214 to the curved guide tube 700, under the action of the reset torque of the torsion spring 800, the hinged rod 521 drives the sealing baffle 522 to be back to the vertical state, and the moving block 511 will gradually return to the initial position under the tension of the tension spring 512, that is, when the partition component 420 completely retreats to the connecting bar hole 213 and the curved guide tube 700, the opening and closing mechanism 500 that is not affected by the partition component 420 will return to the position of blocking the horizontal connecting tube 600, thereby facilitating the opening and closing of the opening and closing mechanism 500.

[0053] It is worth noting that, to improve the smoothness of the hinged rod 521 in driving the sealing shield 522 to return to its original position, the edges of the sealing shield 522 can be chamfered (not shown), and the edges of the sealing shield 522 can be coated with polytetrafluoroethylene to reduce frictional resistance. Furthermore, when the sealing shield 522 is avoiding the partition assembly 420, the upper end of the hinged rod 521 is also tilted, and the highest point of the hinged rod 521 is vertically higher than the lower wall of the limit bar 216. Therefore, even under the rebound tension of the tension spring 512, the hinged rod 521 and the sealing shield 522 remain stuck in the tilted position due to the dual restraint of the limit bar 216 and the partition assembly 420. Only after the partition assembly 420 retracts from the side groove 214 will the hinged rod 521 and the sealing shield 522 be reset under the elastic force of the tension spring 512 and the torsion spring 800.

[0054] In some embodiments, Figure 3 As shown, a first drain pipe 910 is provided on the side wall of the first filter box 210, communicating with the first cleaning gap. A first drain valve 920 is provided on the first drain pipe 910, and the drain end of the first drain pipe 910 is connected to a first waste liquid storage tank 930. Furthermore, a second drain pipe 940 is provided on the side wall of the second filter box 210, communicating with the second cleaning gap. A second drain valve 950 is provided on the second drain pipe 940, and the drain end of the second drain pipe 940 is connected to a second waste liquid storage tank 960. On this basis, since the pollutants on the upper surface of the filter element 220 will remain in the first cleaning gap or the second cleaning gap after being cleaned, the pollutants can be mixed with water and flow into the first waste liquid storage tank 930 or the second waste liquid storage tank 960 through the first drain valve 920 or the second drain valve 950, so that the pollutants in the first cleaning gap or the second cleaning gap are mostly emptied. This part of the waste liquid is more seriously polluted and can be transported to a sewage treatment plant for treatment to meet the treatment standards of the sewage treatment plant. At the same time, water with different degrees of pollution corresponds to different treatment methods, which can greatly reduce the cost of sewage treatment.
