Description

Technical Field

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

[0002] In the field of environmental protection and water resources management, raw water treatment and purification technology is an important link to ensure the safety and sustainable use of water resources. Raw water usually refers to untreated natural water bodies, including river water, lake water, well water, etc., which contain a variety of impurities, such as suspended matter, microorganisms, organic matter, inorganic salts, heavy metal ions and possible pathogens. These impurities not only lead to deterioration of water quality, but also may pose a threat to human health. Therefore, it is of great significance to develop efficient raw water treatment and purification technology.

[0003] At present, for water bodies with different pollution levels, conventional treatment methods include testing the raw water quality to assess the pollution level and select appropriate purification processes accordingly. For moderately and severely polluted water, complex water purification systems in sewage treatment plants are usually used for deep treatment. However, for raw water with a lower pollution level (i.e., low-pollution water), although its pollution does not reach the standard for direct use, returning it to the sewage treatment plant for treatment will lead to a waste of resources, because the traditional sewage treatment system has a complex process and is designed for highly polluted water, and the treatment needs of low-pollution water are obviously not effectively matched.

[0004] In addition, the existing technology lacks a special purification solution for low-pollution water, which makes it impossible to use low-pollution water directly and fails to optimize resource utilization in the existing sewage treatment system, restricting the efficient management of low-pollution water resources. Therefore, how to develop an efficient, economical and suitable purification technology for low-pollution water has become a key problem that the existing technology needs to solve urgently.

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 directly flows into the water storage tank through the lower area for storage.

[0020] After long-term use, the upper surface of the filter element in the first group of filter boxes may be attached with a large amount of residual pollutants due to long-term blocking of slightly polluted water, thereby blocking the upper surface of the filter element, making it impossible for slightly polluted water to pass through the upper area to 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 group of filter mechanisms can be allowed to perform filtering instead, while treating the pollutants on the surface of the filter element in the first group of filter mechanisms. The specific operations are as follows:

[0021] The isolation cleaning mechanism is started, so that a part of the isolation cleaning mechanism enters the upper area of ​​the first group, and forms a first cleaning gap with the upper surface of the first group of filters. In this process, the isolation cleaning mechanism drives the opening and closing mechanism to be in an open state, so that the slightly polluted water in the upper area of ​​the first group located above the first cleaning gap enters the upper area of ​​the second group through the transverse connecting pipe, and is filtered normally through the filter 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 can be cleaned by the isolation cleaning mechanism. After cleaning, the first group of filter mechanisms can be put into normal use, but the second group of filter mechanisms are already in use at this time, so when the second group of filter mechanisms cannot filter the slightly polluted water normally, switch back to the first group of filter mechanisms and clean the second group of filter mechanisms at the same time.

[0022] After such a setting, slightly polluted water can be filtered in the above manner, and there is no need for the sewage treatment plant to consume a large amount of resources to purify slightly polluted water. The above device can be used to treat the micro-polluted water alone, which greatly saves the cost of treating the micro-polluted water. In addition, the above device can be reused continuously. When a filtering failure occurs, uninterrupted filtering can be achieved by switching between the two sets of filtering mechanisms, avoiding the huge power consumption caused by restarting the device after pausing it, and greatly reducing its treatment cost.

DETAILED DESCRIPTION

[0038] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0039] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0040] The following is combined with Figures 1 to 12 , a low-cost micro-polluted water supply treatment device provided by the present application is described in detail through specific embodiments and application scenarios.

[0041] Please refer to Figure 1~Figure 3 A low-cost micro-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 micro-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 micro-polluted water. The water storage tank 300 is connected to the filtering mechanism 200, and the water storage tank 300 is used to store filtered water.

[0042] 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 height of the upper area 211 is greater than the height of the lower area 212, and the filter mechanism 200 is provided with two groups side by side, the upper areas 211 in the two groups of filter mechanisms 200 are connected through a transverse connecting pipe 600, the upper area 211 in the first group of filter mechanisms 200 is connected to the water pipe 100, and the lower areas 212 in the two groups of filter mechanisms 200 are connected to the water storage tank 300 through a drainage pipe. Further, 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 special materials. Among these filter materials, the sand filter material can be selected from manganese sand, etc., which can be used to remove metal ions such as iron and manganese in water. The porous medium material can be selected from activated carbon, etc., which has a very high adsorption capacity and is suitable for removing organic pollutants, odors, chromaticity, etc. The fiber filter material can be polypropylene fiber and glass fiber. Polypropylene fiber is used for deep filtration and can effectively remove tiny suspended matter and grease. Glass fiber is suitable for filtration in high temperature environments and is often used in industrial wastewater treatment. The membrane material can be selected from microfiltration membrane, ultrafiltration membrane and reverse osmosis membrane. Microfiltration membrane can remove bacteria, macromolecular organic matter and suspended solids. Ultrafiltration membrane is used to remove bacteria, viruses and most organic matter. Reverse osmosis membrane is suitable for removing dissolved salts, heavy metals and small molecular organic matter, and can be widely used in deep water purification. The particle filter material can be garnet sand. Garnet sand has high density and good filtration performance, and is suitable for the removal of heavy metals and suspended solids.

[0043] Exemplarily, the device also includes an isolation and cleaning mechanism 400 and an opening and closing mechanism 500, wherein the isolation and cleaning mechanism 400 is arranged between the two groups of filtering mechanisms 200, and the isolation and cleaning mechanism 400 has a switchable first state and a second state, wherein, 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, and 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, and 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.

[0044] Exemplarily, the opening and closing mechanism 500 is arranged 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 and 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 and cleaning mechanism 400, so that the two groups of upper areas 211 are connected; when the isolation and 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 and cleaning mechanism 400, so that the two groups of upper areas 211 are separated.

[0045] 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 boxes 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 purifying the water after passing through the filter element 220, and the purified water flows directly to the water storage tank 300 through the lower area 212 for storage.

[0046] After long-term use, the upper surface of the filter element 220 in the first filter box 210 may be attached with a large amount of residual pollutants due to long-term blocking of slightly polluted water, thereby blocking the upper surface of the filter element 220, so that the slightly polluted water cannot pass through the upper area 211 normally into the lower area 212. At this time, it is necessary to treat the pollutants attached to the upper surface of the filter element 220. During treatment, in order not to affect the normal purification of slightly polluted water, the second filter mechanism 200 can be used to filter instead, while treating the pollutants on the surface of the filter element 220 in the first filter mechanism 200. The specific operation is as follows:

[0047] The isolation cleaning mechanism 400 is started, so that a part of the isolation cleaning mechanism 400 enters the upper area 211 of the first group, and forms a first cleaning gap with the upper surface of the first group of filter elements 220. In this process, the isolation cleaning mechanism 400 drives the opening and closing mechanism 500 to be in an open state, so that the slightly polluted water located above the first cleaning gap in the first group of upper area 211 enters the second group of upper area 211 through the transverse connecting pipe 600, and is filtered normally through the filter element 220 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 220 can be cleaned by the isolation cleaning mechanism 400. After cleaning, the first group of filter mechanisms 200 can be put into normal use, but the second group of filter mechanisms 200 is already in use at this time, so when the second group of filter mechanisms 200 cannot filter the slightly polluted water normally, it can be switched back to the first group of filter mechanisms 200 and the second group of filter mechanisms 200 can be cleaned at the same time.

[0048] After such arrangement, the slightly polluted water can be filtered in the above manner, and the sewage treatment plant does not need to consume a large amount of resources to purify the slightly polluted water. The above device can be used to treat the slightly polluted water alone, which greatly saves the cost of treating the slightly polluted water. In addition, the above device can be reused continuously. When a filtering failure occurs, the two sets of filtering mechanisms 200 can be switched to achieve uninterrupted filtering, avoiding the huge power consumption caused by restarting the device after pausing the device, thereby greatly reducing its treatment cost.

[0049] In some embodiments, Figure 2 , Figure 3 as well as Figure 4As shown, the isolation and cleaning mechanism 400 includes a driving component 410 and a partition component 420. The driving component 410 is installed between the two groups of filtering mechanisms 200. Two groups of partition components 420 are movably provided on the driving component 410. Under the driving action of the driving 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 is separated from the first group upper area 211 while the other moves to the second group upper area 211 to form a second cleaning gap.

[0050] Exemplarily, the driving assembly 410 includes a fixed base 411, a motor 412, a guide rod 413, a threaded sleeve 414 and a threaded rod 415, wherein the fixed base 411 is hollow, and exemplary, the fixed base 411 is mounted on the upper top wall of the water storage tank 300. Further, the motor 412 is mounted in the fixed base 411, 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 are separated by a limiting portion, and the threaded sleeve 414 is respectively provided on the first threaded segment 4151 and the second threaded segment 4152, and one threaded sleeve 414 is correspondingly connected to a group of partition assemblies 420. Exemplarily, the motor 412 is a servo motor, which can achieve reverse rotation after forward rotation, and has a high degree of compatibility with the present device.

[0051] 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 slidably cooperates with the guide rod 413 through the guide hole 414 a.

[0052] 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.

[0053] On this basis, after the motor 412 is started, 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 will not rotate, so the threaded sleeve 414 will be driven to move in the length direction of the threaded rod 415. When the two groups 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 it is also convenient to separate the upper surface of the first group of filters 220 from the flow path of the circulating micro-polluted water. At the same time, the partition assembly 420 connected to the threaded sleeve 414 in the second threaded section 4152 gradually withdraws from the upper area 211 in the second group of filter boxes 210, so that the slightly polluted water can normally enter the upper area 211 of the second group from the upper area 211 of the first group through the transverse connecting pipe 600, and enter the water storage tank 300 from the lower area 212 of the second group of filter mechanisms 200 under the filtering action of the second group of filter elements 220 for storage. When the two groups of threaded sleeves 414 move vertically upward at the same time, the above working process is reversed, which will not be described in detail here.

[0054] 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 be filtered synchronously without pausing 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.

[0055] 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 pipe section 720 and a horizontal pipe section 730 connected in sequence, and a connecting strip 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 strip hole 213. Furthermore, the sum of the diameter of the partition rod 422 and the thickness of the silicone sealing film sleeve 421 is the same as the width of the connecting strip hole 213, and the surface of the silicone sealing film sleeve 421 is slidably sealed with the inner wall of the connecting strip hole 213 to prevent leakage of slightly polluted water in the upper area 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 to form the first cleaning gap, the other part of the plurality of partition rods 422 is still in the curved guide tube 700, so that the sealing performance at the connecting strip hole 213 can be improved to prevent leakage of slightly polluted water.

[0056] Exemplarily, a side groove 214 is horizontally opened on the inner wall of the upper area 211 of the filter box 210, and the side groove 214 and the connecting bar hole 213 are on the same horizontal plane. The side groove 214 is used for the end of the partition assembly 420 entering the upper area 211 to slide horizontally;

[0057] Exemplarily, 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.

[0058] After being configured 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 partition assembly 420 corresponding to the first group of filter mechanisms 200 is partially filled in the side groove 214, and finally the first cleaning gap is formed under the partition effect of the partition assembly 420. In this process, the partition assembly 420 corresponding to the second filter mechanism 200 will withdraw from the side groove 214 and the curved guide tube 700 in sequence, so that the second cleaning gap disappears with the gradual withdrawal of the corresponding partition assembly 420, so that the slightly polluted water entering the upper area 211 of the second filter mechanism 200 through the transverse connecting tube 600 can be filtered normally through the second filter element 220. When the threaded sleeve 414 in the first threaded section 4151 moves vertically upward, its working principle is opposite to the above process, which will not be repeated here.

[0059] In some embodiments, Figure 7 as well as Figure 8 As shown, adjacent ends of adjacent partition rods 422 are provided with lugs 4221, and two adjacent lugs 4221 are provided with through holes, and rotating rods 4222 are inserted into the two through holes, and the two adjacent lugs 4221 can rotate relative to each other around the rotating rods 4222. Exemplarily, both ends of the rotating rods 4222 are provided with limit blocks, and the limit blocks can prevent the rotating rods 4222 from being separated from the through holes.

[0060] Exemplarily, both sides of the lug 4221 are inclined surfaces, and a rotation gap is formed between two adjacent inclined surfaces, and along the extension direction perpendicular to the rotation rod 4222, the width of the rotation gap gradually decreases from the side away from the rotation rod 4222 to the side close to the rotation rod 4222. After such a configuration, the two lugs 4221 can realize the relative bending between the two adjacent partition rods 422, so that the multiple partition rods 422 hinged in sequence can realize the corresponding curvature change when moving in the curved guide tube 700, and can also realize normal switching between the vertical state and the horizontal state. In addition, under the action of the rotation gap, the relative bending angle between the two adjacent partition rods 422 can be increased, so as to improve the smoothness of the movement of the multiple partition rods 422 in the curved guide tube 700 to a certain extent.

[0061] In some embodiments, in combination Figure 2 , Figure 4 , Fig. 9 as well as Fig.10 The isolation cleaning mechanism 400 further includes a flushing assembly 430, which includes a backwashing pump 431, a first pipe body 432, a second pipe body 433, a hose 434, a branch pipe 435, and a high-pressure nozzle 436, wherein the pump inlet of the backwashing pump 431 is connected to the water storage tank 300 through the first pipe body 432, the second pipe body 433 is connected to the pump outlet of the backwashing pump 431, the interior of the partition rod 422 is hollow, the hose 434 passes through a plurality of partition rods 422 in sequence, and one end of the hose 434 is connected to the second pipe body 433. Exemplarily, the second pipe body 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 pipe body 433.

[0062] 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 sprayed 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. Exemplarily, the entire high-pressure nozzle 436 does not extend out of the partition rod 422, but a hole body connected to the hollow portion 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.

[0063] For example, among the plurality of partition rods 422, only the partition rod 422 that can slide into the side groove 214 has the high-pressure nozzle 436, while the partition rod 422 that cannot slide into the side groove 214 does 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 in the connecting bar hole 213, blocking the connecting bar hole 213.

[0064] On this basis, when a portion of the multiple partition rods 422 have 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 storage 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 is finally 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.

[0065] In some embodiments, in combination Figure 3 , Figure 4 , Fig.11 as well as Fig.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.

[0066] 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 to horizontally move 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.

[0067] Exemplarily, the moving assembly 510 includes a moving block 511 and a tension spring 512. A horizontal groove 215 is provided on the inner wall of the first group of filter boxes 210 and above the side groove 214 in parallel for the moving block 511 to slide. 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.

[0068] Exemplarily, the shielding assembly 520 includes a hinged rod 521 and a sealing shielding plate 522. The hinged rod 521 is hinged on the moving block 511 through a torsion spring 800. The sealing shielding plate 522 is arranged 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 strip 216 is arranged on the inner wall of the first group of filter boxes 210 and above the horizontal groove 215 in parallel. The length of the limit strip 216 is less than the length of the horizontal groove 215. The upper end surface of the hinged rod 521 is a plane and can be slidably fitted on the lower wall surface of the limit strip 216. In the embodiment, when the torsion spring 800 is in a natural state, the hinge rod 521 is in a vertical state and the upper end surface of the hinge rod 521 is limited and fits on the lower wall surface of the limiting strip 216, so as to prevent the hinge rod 521 from rotating when the partition assembly 420 moves in the side groove 214 and pushes the sealing baffle plate 522 to move horizontally; when the partition assembly 420 moves in the side groove 214 and pushes the sealing baffle plate 522 to move until the upper end surface of the hinge rod 521 is separated from the limiting strip 216, the sealing baffle plate 522 rotates around the torsion spring 800 under the continued push of the partition assembly 420 and avoids the partition assembly 420.

[0069] On this basis, when part of the partition assembly 420 enters the side groove 214 through the curved guide tube 700 and moves horizontally in the side groove 214, the end of the partition assembly 420 will first abut against the sealing shielding plate 522. At this time, since the top of the hinge rod 521 is a plane and slides in contact with the lower wall of the limit strip 216, the hinge rod 521 cannot rotate around the hinge point under the restriction of the fit between the two, so that the sealing shielding plate 522 moves in a length direction parallel to the limit strip 216 under the push of the partition assembly 420. In this process, the sealing shielding plate 522 will move horizontally so that the pipe opening of the transverse connecting pipe 600 located in the upper area 211 of the first group of filtering mechanisms 200 is opened. 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 is disengaged 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 plate 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 plate 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.

[0070] 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 hinge rod 521 drives the sealing baffle plate 522 to be in a vertical state again, 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 strip 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 transverse connecting tube 600, thereby facilitating the opening and closing of the opening and closing mechanism 500.

[0071] It is worth noting that in order to improve the smoothness of the hinge rod 521 driving the sealing shielding plate 522 to reset, the edge of the sealing shielding plate 522 can be chamfered (not shown in the figure), and the edge of the sealing shielding plate 522 is coated with polytetrafluoroethylene to reduce friction resistance. At the same time, when the sealing shielding plate 522 is in the state of avoiding the partition assembly 420, the upper rod end of the hinge rod 521 is also in an inclined state, and the highest point of the hinge rod 521 is higher than the height of the lower wall surface of the limit bar 216 in vertical height. In this way, even under the rebound tension of the tension spring 512, the hinge rod 521 and the sealing shielding plate 522 will still be stuck in an inclined state under the double limit of the limit bar 216 and the partition assembly 420, until the partition assembly 420 retreats from the side groove 214, the hinge rod 521 and the sealing shielding plate 522 will be reset under the elastic force of the tension spring 512 and the torsion spring 800.

[0072] In some embodiments, Figure 3 As shown, a first drain pipe 910 connected to the first cleaning gap is provided on the side wall of the first filter box 210, a first drain valve 920 is provided on the first drain pipe 910, and a drain end of the first drain pipe 910 is connected to a first waste liquid storage tank 930. Further, a second drain pipe 940 connected to the second cleaning gap is provided on the side wall of the second filter box 210, a second drain valve 950 is provided on the second drain pipe 940, and a 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 through the first drain valve 920 or the second drain valve 950 to flow into the first waste liquid storage tank 930 or the second waste liquid storage tank 960, 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.
