Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, in particular to a solar sewage treatment device utilizing water resources. Background Art

[0002] Wastewater treatment mainly refers to the process of purifying wastewater to meet the water quality requirements for discharge into a water body or reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical treatment, catering, etc., and is increasingly entering the daily lives of ordinary people.

[0003] Sewage treatment is classified by the source of sewage, generally divided into industrial sewage treatment and domestic sewage treatment. Industrial sewage includes industrial sewage, agricultural sewage and medical sewage, while domestic sewage is sewage generated in daily life, which refers to a complex mixture of various forms of inorganic and organic matter, including: floating and suspended large and small solid particles; colloidal and gelatinous diffusions; pure solutions.

[0004] Sewage treatment is divided into two categories according to the nature of water pollution: one is natural pollution; the other is man-made pollution. Currently, man-made pollution is the most harmful to water bodies. Water pollution can be divided into three categories according to the different pollutants: chemical pollution, physical pollution and biological pollution. The main pollutants are: untreated industrial wastewater; untreated domestic sewage; agricultural sewage with large amounts of fertilizers, pesticides and herbicides; industrial waste and domestic garbage piled up by the river; soil erosion; and mine sewage.

[0005] There are many ways to treat sewage, which can generally be summarized as physical, chemical and biological methods. Common products for sewage treatment include: quartz sand filter material, anthracite filter material, polyaluminium chloride, activated carbon, honeycomb inclined tube filler, fiber ball filter material, garnet sand, etc.

[0006] The patent document with announcement number CN215352219U discloses a sewage treatment environmental protection device, which can adjust the inclination angle of the water spray plate through the first hydraulic cylinder braking, thereby adjusting the irrigation angle. The second hydraulic cylinder braking can drive the top cover to rise and fall, which is convenient for cleaning, repairing and replacing the stirring rod, so that the distance sensor on the base is energized and braked. When an obstacle is sensed, the distance sensor can control the first drive motor to brake through the controller, thereby driving the roller to change direction to avoid collision. When the water level sensor in the sewage treatment tank senses that the bottom water level drops to the set position, the water level sensor can control the electromagnetic heating plate to brake through the controller to heat the inside of the sewage treatment tank, thereby drying the sludge in the filter drawer. After drying, it is pulled out through the outer handle to facilitate the cleaning and later use of the sludge.

[0007] In an anti-clogging urban sewage treatment device with announcement number CN115784401B, when treating sewage, sewage enters the sewage chamber from the water inlet; then the driving structure drives the filter screen to begin to separate from the baffle; at this time, water enters the clean water chamber from the through hole of the baffle, and the sewage is filtered through the filter screen; in addition, as the filter screen moves, it will resist the extrusion block, so that the water in the water storage box is squeezed by the extrusion block and sprayed from the water outlet, and reversely impacts the filter screen, so that impurities on the filter screen are flushed into the sewage chamber; therefore, the filter screen can be cleaned while filtering sewage, thereby preventing blockage and improving the effect of sewage treatment.

[0008] However, in the process of implementing the above technical solution, it is found that the above technical solution has the following technical problems:

[0009] The water used to backwash the filter is affected by the sewage passing through the filter and the resistance caused by the continuous accumulation of debris, which can easily affect the flushing effect: the sewage treatment environmental protection device (Announcement No.: CN215352219U) automatically lifts and lowers the top cover of the sewage treatment tank, which is convenient for cleaning, repairing and replacing the stirring rod. In actual use, the efficiency of active disassembly and cleaning is low (routine problems will not be elaborated on);

[0010] The urban sewage treatment device (Announcement No.: CN115784401B) uses water to reversely impact the filter so that the impurities on the filter are flushed into the sewage cavity to prevent the filter from being blocked. This method can, to a certain extent, prevent debris from filling the filter mesh. As the debris continues to accumulate, the flushing effect will become worse and worse. In normal use, it is easy to block the reverse flushing water due to the resistance generated when the sewage passes through the filter, which ultimately affects the flushing effect. Summary of the invention

[0011] In order to overcome the problem that the existing urban sewage treatment device adopts a method of spraying water from the clean water chamber into the sewage chamber to flush the filter screen, which can prevent debris from filling the filter mesh to a certain extent. As the debris continues to accumulate, the flushing effect will become worse and worse. In conventional use, it is easy to form a barrier to the backwashing water due to the resistance generated when the sewage passes through the filter screen, which ultimately affects the flushing effect. The embodiment of the present application provides a solar sewage treatment device for water resource utilization, which drives the control disk to rotate by using a rotating cylinder to control the transmission column, thereby driving the filter cartridge to rotate inside the main body of the sewage treatment device. When the sewage carrying debris enters the interior of the sewage treatment device, the sewage passes through the interior of the filter screen, and the debris is blocked by the filter screen and collected inside the storage slot, so that the filter cartridge drives the debris to one side of the water outlet cover A, so that the submersible pump draws water from the inner side of the bottom of the main body of the sewage treatment device and discharges it from the multiple water spray holes inside the water outlet plate through the water supply pipe and the inside of the vertical cylinder, and flushes the filter screen from the inside to the outside, so that the sprayed water will not conflict with the water discharged into the main body of the sewage treatment device, thereby ensuring the cleaning effect of the filter screen.

[0012] The technical solution adopted by the embodiment of the present application to solve the technical problem is:

[0013] A solar sewage treatment device for water resource utilization comprises a sewage treatment device body and a collecting cylinder, wherein the collecting cylinder is arranged at the bottom of one side of the sewage treatment device body;

[0017] The sewage is input from the outside to the inside of the filter structure, and the debris is blocked outside the filter structure. The sewage enters the inside of the filter structure and is collected at the bottom of the main body of the sewage treatment device. The submersible pump draws water from the inside of the bottom of the main body of the sewage treatment device and flushes the filter structure from the inside to the outside, so that the debris is discharged into the inside of the collection cylinder.

[0018] The submersible pump collects sewage at the bottom of the sewage treatment device body through the switching structure to pump water. When the sewage is discharged to the outside through the sewage pipe and the sewage level is lower than the top of the switching structure, the switching structure is used to switch the channel and water is pumped from the inside of the collection tube with the help of the pumping pipe.

[0019] In some examples, a plurality of limit strips are processed on the inner wall of the filter cartridge, four water passage slots are processed inside the filter cartridge, filter frames are provided at the four water passage slots, and the filter net is embedded in the filter frame.

[0020] In some examples, a water inlet cover B is processed on the top outer wall of the sewage treatment device body, a water outlet cover A is processed on the middle outer wall of the sewage treatment device body, one side of the water inlet cover B is assembled with the water inlet cover A, a delivery pipe is processed on the top of one side of the water inlet cover A, a water outlet cover B is processed on the top outer wall of the collecting cylinder, the water outlet cover B and the water outlet cover A are assembled and fixed, and the bottom inner wall after the water inlet cover B and the water inlet cover A are connected is inclined toward the middle of the sewage treatment device body, and the bottom inner wall after the water outlet cover A and the water outlet cover B are connected is inclined toward the bottom of the sewage treatment device body.

[0021] In some examples, a separation ring is processed on the inner wall of the main body of the sewage treatment device, the filter cartridge is movably connected to the top of the separation ring, and one end of the vertical cartridge is assembled and fixed to the top of the separation ring.

[0022] In some examples, the plurality of limit bars are respectively located on both sides of the four receiving slots, one end of the plurality of limit bars are fixed to the inner wall of the filter cartridge, and the two sides of the filter frame are respectively inserted between the plurality of delivery pipes on both sides of the receiving slots and the inner wall of the filter cartridge.

[0023] In some examples, a column is processed at the center of the outer side of the filter frame, and the rotary cylinder drives the control disk to rotate through the transmission column. When driving the filter cartridge, a plurality of limit bars used in conjunction drive the columns on the filter frame to apply pressure to the cartridge, so that the middle part of the filter frame is deformed and the two ends are pressed between the limit bars and the inner wall of the filter cartridge.

[0024] In some examples, a receiving mesh plate is provided inside the collecting cylinder, a pumping joint A is processed on the bottom outer wall of the collecting cylinder, and a pumping joint B is processed on the middle outer wall of the sewage treatment device body.

[0026] In some examples, the connection points of the two second water channels are V-shaped, and the outsides of both ends of the switching column are sleeved with fixed sleeves, and the outer walls of the fixed sleeves are processed with threaded rods. One end of the two threaded rods is fixed to the same float by bolts, and one end of the pumping pipe passes through the main body of the sewage treatment device to the inside of the collection cylinder.

[0027] In some examples, two baffle rods are processed on the outer wall of the switch seat tube, and the two baffle rods are symmetrically arranged on both sides of the switch seat tube. The float moves toward the top due to the buoyancy of the water, pulling the fixed sleeve at one end of the threaded rod to drive the switch column to rotate inside the switch seat tube, and the two baffle rods limit the movement range of the threaded rod.

[0028] The beneficial effects of this application are:

[0029] First, in this solution, the control plate is driven to rotate by using a rotating cylinder to control the transmission column, thereby driving the filter cartridge to rotate inside the main body of the sewage treatment device. When the sewage carrying debris enters the main body of the sewage treatment device, the sewage passes through the inside of the filter screen, and the debris is blocked by the filter screen and collected inside the receiving slot, so that the filter cartridge drives the debris to one side of the water outlet cover A, and the submersible pump draws water from the inside of the bottom of the main body of the sewage treatment device and discharges it from the inside of the multiple water spray holes inside the water outlet plate through the water supply pipe and the inside of the vertical cylinder, and washes the filter screen from the inside to the outside, so that the sprayed water will not conflict with the water discharged into the main body of the sewage treatment device, thereby ensuring the cleaning effect of the filter screen;

[0030] Secondly, in the present scheme, a switching structure is arranged on the water suction pipe connected to one end of the water suction port of the submersible pump, and the float on the switching structure moves toward the top due to the buoyancy of the sewage inside the main body of the sewage treatment device, pulling the threaded rod and the fixed sleeve to drive the switching column to rotate inside the switching seat tube, so that the distal ends of the two second water troughs are connected to the interior of the main body of the sewage treatment device, and the proximal ends of the two second water troughs are connected to the water suction port of the submersible pump. When the sewage is discharged from the interior of the main body of the sewage treatment device through the sewage discharge pipe and the water level drops, the float moves toward the bottom due to the influence of gravity, so that the first water trough connects the two ends of the water suction pipe, so that the submersible pump can extract water from the interior of the main body of the sewage treatment device through one end of the water suction pipe and the switching column, or extract the accumulated water between the receiving net plate and the bottom inner wall of the collecting cylinder through the water suction pipe. The water intake direction can be determined according to the actual situation without affecting the discharge of sewage inside the main body of the sewage treatment device through the sewage discharge pipe to the outside. The submersible pump pumps water into the vertical cylinder and uses the multiple water spray holes on the two water outlet plates to wash the filter screen. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] The technical solution in the embodiment of the present application is to solve the problems of the above-mentioned background technology, and the overall idea is as follows:

[0046] Embodiment 1:

[0047] This embodiment introduces a specific structure of a solar sewage treatment device for water resource utilization. Figure 1-Figure 6 As shown, it includes a sewage treatment device body 8 and a collecting cylinder 11 arranged at the bottom of one side of the sewage treatment device body 8, a filtering structure 20 is arranged on the inner side of the top of the sewage treatment device body 8, a submersible pump 16 is arranged on the inner side of the bottom of the sewage treatment device body 8, a water inlet cover B4 is processed on the top outer wall of the sewage treatment device body 8, a water outlet cover A9 is processed on the middle outer wall of the sewage treatment device body 8, a separating ring 24 is processed on the inner wall of the sewage treatment device body 8, a sewage discharge pipe 7 is processed on the bottom outer wall of the sewage treatment device body 8, and a water outlet cover B12 is processed on the top outer wall of the collecting cylinder 11;

[0048] like Figure 2 As shown, the filter structure 20 includes a filter cartridge 201, and four receiving slots 19 are formed on the outer wall of the filter cartridge 201. Four water-passing slots 21 are processed inside the filter cartridge 201. A filter frame 207 is disposed at each of the four water-passing slots 21. A filter screen 202 is embedded and connected inside the filter frame 207.

[0049] The drainage end of the submersible pump 16 is equipped with a water supply pipe 17, one end of which is assembled and connected with a vertical cylinder 23 (the filter cylinder 201 is movably connected to the top of the separation ring 24, and one end of the vertical cylinder 23 is assembled and fixed to the top of the separation ring 24). Two water outlet plates 22 are processed on the outer wall of the vertical cylinder 23, and multiple water spray holes are processed inside one side of the two water outlet plates 22;

[0050] Among them, sewage is input to the inner side of the filter structure 20 through the water inlet cover B4, and the debris is blocked and collected at the receiving slot 19 outside the filter structure 20. When the filter structure 20 rotates at a fixed angle of 90 degrees, 180 degrees, 270 degrees and 360 degrees, the angle gear is controlled by the rotating cylinder 3, driving the receiving slot 19 on the outer wall of the filter structure 20 to face the water outlet cover A9, so that the blocked debris is released from the receiving slot 19 to the inside of the water outlet cover A9, and finally collected in the inside of the collection tube 11 through the water outlet cover A9 and the water outlet cover B12;

[0051] At the same time, the submersible pump 16 pumps water into the interior of the vertical cylinder 23 through the water supply pipe 17, and then enters the interior of the two water outlet plates 22 through the vertical cylinder 23. Since the water outlet plates 22 are located on the inner side of the filter cylinder 201, water can be sprayed out from the multiple water spray holes on the water outlet plates 22, so that the submersible pump 16 can pump water from the inner side of the bottom of the sewage treatment device body 8 and flush the filter structure 20 from the inside to the outside, so that the debris attached to the inner surface of the filter screen 202 is discharged into the interior of the collection cylinder 11 through the water outlet cover A9 and the water outlet cover B12;

[0052] Secondly, in order to conveniently control the filter structure 20 to rotate inside the top of the sewage treatment device body 8, so as to switch the connection state between the four filter screens 202 and the water outlet cover A9 and the water inlet cover B4, as shown in FIG. Figure 2 As shown, the top of the sewage treatment device body 8 is assembled and connected with a device cover plate 2, and the center of the top of the device cover plate 2 is assembled and connected with a rotating cylinder 3, and a solar panel 1 is mounted on the top of the device cover plate 2 (the solar panel 1 supplies power to the rotating cylinder 3 and the submersible pump 16, and the principle of the solar panel 1 converting solar energy into electrical energy refers to the prior art, and the solar power generation technology has been a mature application in this technical field), and a control disk 204 is assembled and fixed on the outer wall of the top of the filter cartridge 201, and a transmission column 203 is processed at the center of the top of the control disk 204. By making one end of the rotating shaft of the rotating cylinder 3 (assembled to the center of the top of the device cover plate 2) pass through the inside of the device cover plate 2 and pin-connected to the inside of one end of the transmission column 203, when the rotating cylinder 3 is working, the control disk 204 can be driven to rotate, thereby driving the filter cartridge 201 to rotate inside the sewage treatment device body 8;

[0053] Furthermore, in order to facilitate the sewage to carry debris into the inner side of the sewage treatment device body 8, the debris in the sewage is blocked in the receiving slot 19 on the outer wall of the filter cartridge 201, so that after the filter cartridge 201 rotates, the debris falls into the interior of the collection cartridge 11 through the water outlet cover A9 and the water outlet cover B12, as shown in FIG. Figures 1 to 3 As shown, one side of the water inlet cover B4 is assembled and connected with the water inlet cover A6, and the top of one side of the water inlet cover A6 is processed with a conveying pipe 5. By assembling and fixing the water outlet cover B12 and the water outlet cover A9, the bottom inner wall of the water inlet cover B4 and the water inlet cover A6 are inclined toward the middle of the sewage treatment device body 8, and the bottom inner wall of the water outlet cover A9 and the water outlet cover B12 are inclined toward the bottom of the sewage treatment device body 8, so that debris can slide to the bottom along the inclined inner wall, which is convenient for sewage to carry debris into the interior of the sewage treatment device body 8 and be discharged into the interior of the collecting cylinder 11 inside the sewage treatment device body 8;

[0054] In some examples, a plurality of limit strips 205 are processed on the inner wall of the filter cartridge 201, and a column 206 is processed at the center of the outer side of the filter frame 207;

[0055] Among them, by making multiple limiting strips 205 (multiple limiting strips 205 are divided into multiple groups for use, each group includes two rows of limiting strips 205) located on both sides of the four receiving slots 19, after one end of the multiple limiting strips 205 is processed and fixed to the inner wall of the filter cartridge 201, the two sides of the filter frame 207 can be respectively inserted between the multiple conveying pipes 5 (two rows used in combination) on both sides of the receiving slot 19 and the inner wall of the filter cartridge 201, so as to facilitate positioning of the multiple filter frames 207, so that the filter screen 202 inside the filter frame 207 faces the water passing slot 21;

[0056] Secondly, when the rotating cylinder 3 drives the control disk 204 to rotate through the transmission column 203, the filter cartridge 201 rotates accordingly. The filter cartridge 201 drives the four filter frames 207 inside it to rotate. When the filter screen 202 inside the filter frame 207 is switched to a state facing the water inlet cover B4 and the water outlet cover A9, the multiple limit bars 205 used in conjunction can drive the columns 206 on the filter frame 207 to apply pressure to the column 23, so that the middle part of the filter frame 207 is deformed and the two ends are pressed between the limit bars 205 and the inner wall of the filter cartridge 201. After the pressure on the filter frame 207 is released, the filter frame 207 is elastically reset, which is convenient for shaking the filter frame 207 to assist in removing debris on the surface of the filter screen 202 in the form of shaking.

[0057] Embodiment 2:

[0058] Based on Example 1, Figure 1 , Figure 2 , Figure 7 and Figure 8As shown, this embodiment introduces the specific structure of the submersible pump 16. The water pumping end of the submersible pump 16 is assembled and connected with the water pumping pipe 15. One end of the water pumping pipe 15 is provided with a switching structure 25. The switching structure 25 includes a switching seat tube 256. The switching seat tube 256 is rotatably connected with a switching column 254 inside. Two second water troughs 26 and one first water trough 18 are processed inside the switching column 254. The outsides of both ends of the switching column 254 are sleeved with fixed sleeves 253. The outer wall of the fixed sleeve 253 is processed with threaded rods 252. One end of the two threaded rods 252 is assembled and fixed to the same float 251 by bolts.

[0059] The collecting tube 11 is provided with a receiving net plate 14. By providing the receiving net plate 14 inside the collecting tube 11, the receiving net plate 14 is used to receive the debris falling into the collecting tube 11 from the water outlet cover A9 and the water outlet cover B12. The sewage carried by the debris flows to the bottom through the receiving net plate 14 over time and falls between the receiving net plate 14 and the bottom inner wall of the collecting tube 11.

[0060] At the same time, a pumping joint A10 is processed at the outer wall of the bottom of the collecting cylinder 11, and a pumping joint B13 is processed at the outer wall of the middle part of the sewage treatment device body 8. By making one end of the pumping joint B13 droop and assemble and fix it with the pumping joint A10 with one end erected upward, and then movably connecting one end of the pumping pipe 15 to the inside of the pumping joint A10 and the pumping joint B13, so as to pass through the sewage treatment device body 8 to the inside of the collecting cylinder 11, the accumulated water can be pumped out at the bottom of the pumping joint A10, so that the submersible pump 16 can pump water when collecting sewage at the bottom of the sewage treatment device body 8 through the switching structure 25. When the sewage is discharged to the outside through the sewage discharge pipe 7 and the sewage liquid level is lower than the top of the switching structure 25, the switching structure 25 is used to switch the channel, and the pumping pipe 15 is used to pump water from the inside of the collecting cylinder 11;

[0061] Secondly, by forming the switch seat tube 256 integrally on the outside of the delivery pipe 5, the two second water channels 26 are arranged horizontally, and the connection points of the two second water channels 26 at the two ends of the switch column 254 are V-shaped and communicated with the outside of the switch column 254, while the first water channel 18 is arranged vertically and is located on one side of the connection point of the two second water channels 26, so that the first water channel 18 and the two second water channels 26 are arranged alternately, so that it is convenient to rotate the switch column 254 inside the switch seat tube 256, so that the second water channel 26 is connected to the water suction port on the submersible pump 16, and the submersible pump 16 extracts the filtered sewage from the bottom of the sewage treatment device body 8 through the switch column 254;

[0062] At the same time, the switching column 254 is rotated inside the switching seat tube 256, so that the first water trough 18 connects the two ends of the water pumping pipe 15, so that the submersible pump 16 pumps water from the inside of the collecting tube 11 through the water pumping pipe 15 (one end of which extends between the receiving net plate 14 and the bottom inner wall of the collecting tube 11), so as to compensate for the situation that the filtered sewage inside the sewage treatment device body 8 is discharged from the sewage discharge pipe 7, and the submersible pump 16 can no longer pump water to wash the debris on the filter screen 202;

[0063] Furthermore, the rotation of the switching column 254 inside the switching seat tube 256 is affected by the height of the liquid level of the filtered sewage in the sewage treatment device body 8 along with the float 251. When the float 251 is immersed in the sewage, it floats to the top, and drives the switching columns 254 inside the two fixing sleeves 253 to rotate inside the switching seat tube 256 through the two threaded rods 252, so that the distal ends of the two second water channels 26 are connected to the interior of the sewage treatment device body 8, and the proximal ends of the two second water channels 26 are connected to the water inlet of the submersible pump 16.

[0064] At the same time, when the sewage in the sewage treatment device body 8 is discharged from the sewage pipe 7, causing the water level to drop, the float 251 is affected by gravity, driving the switching column 254 inside the two fixed sleeves 253 to rotate inside the switching seat tube 256, so that the first water trough 18 connects the two ends of the water pumping pipe 15, so that the submersible pump 16 can pump water from the inside of the collection tube 11 through the water pumping pipe 15;

[0065] Furthermore, in order to ensure that the float 251 can only move to one side under the influence of gravity, Figure 7 and Figure 8 As shown, two baffle rods 255 are processed on the outer wall of the switching seat tube 256. By symmetrically arranging the two baffle rods 255 on both sides of the switching seat tube 256, when the float 251 moves toward the top due to the buoyancy of the water, the fixing sleeve 253 at one end of the threaded rod 252 is pulled to drive the switching column 254 to rotate inside the switching seat tube 256, and the two baffle rods 255 limit the movement range of the threaded rod 252, thereby controlling the movement range of the threaded rod 252, and finally controlling the activity range of the float 251.

[0066] Specifically, when using the solar sewage treatment device utilizing water resources to treat sewage:

[0067] First, the sewage carrying debris is passed into the interior of the sewage treatment device body 8 through the conveying pipe 5, the water inlet cover A6 and the water inlet cover B4, so that the sewage passes through the interior of a filter screen 202 on the filter cartridge 201 and falls to the bottom, and the collection work is completed at the bottom inner wall of the sewage treatment device body 8, and the filtered debris is collected between the inside of the receiving slot 19 outside the filter cartridge 201 and the inner wall of the sewage treatment device body 8 (the debris in the sewage is guided to the inside of the receiving slot 19 by the bottom inclined inner wall of the water inlet cover A6 and the water inlet cover B4);

[0068] Then, the rotating cylinder 3 drives the control disk 204 to rotate through the transmission column 203, thereby driving the filter cartridge 201 to rotate inside the main body 8 of the sewage treatment device, so that the filter cartridge 201 drives the debris in the receiving slot 19 at its outer wall to the side of the water outlet cover A9, and then discharged into the interior of the collecting cylinder 11 through the water outlet cover A9 and the water outlet cover B12 (the filtered debris is guided to the interior of the collecting cylinder 11 along the inclined inner wall at the bottom of the water outlet cover A9 and the water outlet cover B12), and is received by the receiving net plate 14 inside the collecting cylinder 11 (the accumulation of debris causes part of the sewage to penetrate into the interior of the receiving net plate 14, and is collected at the receiving net plate 14 and the bottom inner wall of the collecting cylinder 11, so that water is stored between the receiving net plate 14 and the bottom inner wall of the collecting cylinder 11);

[0069] Next, the float 251 moves toward the top due to the buoyancy of the water, pulling the fixed sleeve 253 at one end of the threaded rod 252 to drive the switching column 254 to rotate inside the switching seat tube 256, so that the distal ends of the two second water channels 26 are connected to the interior of the sewage treatment device body 8, and the proximal ends of the two second water channels 26 are connected to the water suction port of the submersible pump 16, so that the submersible pump 16 can extract water from the interior of the sewage treatment device body 8 through one end of the water suction pipe 15 and the switching column 254, and transport it to the interior of the vertical cylinder 23 through the water supply pipe 17, and then enter the interior of the two water outlet plates 22 through the vertical cylinder 23, and finally make the water spray out from the multiple water spray holes on the water outlet plate 22, and finally wash the filter screen 202 from the inside of the filter cylinder 201 to the outside, so that the debris attached to the inner surface of the filter screen 202 is discharged into the interior of the collecting cylinder 11 through the water outlet cover A9 and the water outlet cover B12, so as to prevent the debris from adhering to the surface of the filter screen 202 and affecting the filtering effect of the sewage;

[0070] Subsequently, the sewage collected inside the sewage treatment device body 8 is discharged to the outside through the sewage discharge pipe 7, and the sewage liquid level inside the sewage treatment device body 8 is continuously reduced. When the float 251 moves toward the bottom under the influence of gravity, the switching column 254 is driven to rotate inside the switching seat tube 256 through the two threaded rods 252 and the two fixed sleeves 253, so that the first water trough 18 connects the two ends of the suction pipe 15 (and the connecting ends of the two second water troughs 26 are blocked by the inner wall of the switching seat tube 256), so that the water accumulated between the receiving net plate 14 and the bottom inner wall of the collecting tube 11 is pumped out from the inside of the collecting tube 11 by the submersible pump 16 through the suction pipe 15, without affecting the sewage inside the sewage treatment device body 8 to be discharged to the outside through the sewage discharge pipe 7. The submersible pump 16 pumps water into the vertical tube 23, and uses the multiple water spray holes on the two water outlet plates 22 to wash the filter screen 202.

[0071] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
