When treating raw wastewater, the water inlet 2 is used to transport the wastewater to the interior of the treatment box 1, and then the wastewater contacts the diverter plate 4. Since the uppermost and lowermost through grooves 5 are closed, the wastewater will pass through the gap between the diverter plate 4 and the treatment box 1 and the through groove 5 in the middle. When the wastewater passes through, it is filtered by the two filter plates 6 and then discharged through the water outlet 3. After the filter plates 6 have worked for a long time, the two filter plates 6 are controlled by the cleaning structure to rise and fall respectively, and they are cleaned. Through the above structure, when treating wastewater generated in the city, the problem of clogging of the filter plates 6 due to long-term use and thus reducing the purification speed can be avoided to a certain extent, and the tedious work of stopping work for cleaning can be avoided to a certain extent.

[0031] Furthermore, the cleaning structure includes a motor 7, which is fixedly connected to the upper surface of the treatment box 1, and the output end of the motor 7 is fixedly connected to a worm 8, and the lower end of the worm 8 rotates and penetrates into the interior of the treatment box 1. The inner wall of the treatment box 1 is rotatably connected to a rotating rod 9, and the outer surface of the rotating rod 9 is sleeved with a worm gear 10, and the outer surface of the worm gear 10 is meshed with the worm 8. The outer surface of the rotating rod 9 is meshed with a gear 11, and the side surfaces of the two filter plates 6 are fixedly connected with a tooth plate 12, and the two tooth plates 12 are meshed with the gear 11. The bottom wall of the uppermost through groove 5 is provided with a sewage outlet 13, and the sewage outlet 13 extends out of the lower surface of the treatment box 1 The bottom through groove 5 is also communicated with the sewage outlet 13. The two filter plates 6 are located on one side of the diverter plate 4. The inner wall of the filter groove 14 is fixedly connected with a filter screen. The lower surface of the right filter plate 6 is flush with the lower surface of the diverter plate 4. The upper surface of the treatment box 1 is fixedly connected with a water tank 15. A water pump 16 is arranged inside the water tank 15. The output end of the water pump 16 is fixedly connected with a water pipe 17. The lower end of the water pipe 17 passes through the interior of the bottom through groove 5. The top through groove 5 is also communicated with the water pipe 17. The inner wall of the treatment box 1 is fixedly connected with a baffle plate 18. The left side surface of the baffle plate 18 is connected to the left inner wall of the treatment box 1. The walls are fixedly connected with a slow flow plate 19. After the wastewater enters the treatment box 1, it contacts the slow flow plate 19. The slow flow plate 19 reduces the flow rate of the wastewater, and then the wastewater enters the diverter plate 4 for filtration. During cleaning, the motor 7 synchronously drives the worm 8 to rotate, the worm 8 synchronously drives the worm wheel 10 to rotate, the worm wheel 10 synchronously drives the rotating rod 9 to rotate, and the rotating rod 9 synchronously drives the gear 11 to rotate. The rotation of the gear 11 causes the two tooth plates 12 to rise and fall respectively, and the tooth plate 12 drives the filter plate 6 to move. The filter plate 6 rises so that part of the filter screen located in the middle through groove 5 enters the interior of the upper through groove 5, as well as the filter screen located between the diverter plate 4 and the treatment box 1 Part of the filter screen between the bottom walls enters the interior of the lower groove 5, and the filter plate 6 descends so that the part of the filter screen located in the upper groove 5 and the lower groove 5 enters the middle groove 5 and the lower gap respectively, and then the water pump 16 is used to transport water to the water pipe 17, and the water pipe 17 transports the water flow to the interior of the upper and lower grooves 5. The reverse impact of the water flow washes down the residue and dirt on the filter screen and discharges it through the sewage outlet 13. Through the above structure, when cleaning the filter screen, automatic cleaning can be easily completed without shutting down the treatment device, which effectively improves the efficiency of cleaning the filter screen and at the same time improves the continuity of wastewater treatment.

[0032] A fixed limiting rod 20 is fixedly installed inside the slow flow plate 19, and a lifting plate 23 is slidably connected on the surface of the fixed limiting rod 20. The lifting plate 23 is slidably connected inside the slow flow plate 19. A return spring 28 is movably sleeved on the surface of the fixed limiting rod 20, and the upper end of the return spring 28 is fixedly connected to the bottom of the lifting plate 23, and the lower end of the return spring 28 is fixedly connected to the inside of the slow flow plate 19. A connecting rod 24 is fixedly installed on the top of the lifting plate 23, and a knocking ball 21 is fixedly installed on the upper end of the connecting rod 24, and a rubber sleeve 22 is fixedly sleeved on the surface of the knocking ball 21. A driving motor 27 is fixedly installed inside the slow flow plate 19, and a half gear 26 is fixedly installed on the output end of the driving motor 27. A rack 25 is fixedly installed on the bottom of the lifting plate 23, and the rack 25 is meshingly connected with the half gear 26.

[0033] When the driving motor 27 is started, the driving motor 27 drives the half gear 26 to rotate, and since the half gear 26 is meshed with the rack 25, the rack 25 and the lifting plate 23 are driven to move downward, so that the knocking ball 21 and the rubber sleeve 22 are no longer in contact with the inner wall of the slow flow plate 19, and the lifting plate 23 is made to slide on the two fixed limiting rods 20 and squeeze the two return springs 28. Since there are only half teeth on the half gear 26, as the driving motor 27 drives the half gear 26 to continue to rotate, the half gear 26 is no longer meshed with the rack 25, and the lifting plate 23, the knocking ball 21 and the rubber sleeve 22 are reset by the elastic force of the return spring 28, so that the knocking ball 21 and the rubber sleeve 22 knock on the inner wall of the slow flow plate 19, so that the slow flow plate 19 vibrates, so as to facilitate the shaking off of impurities on the slow flow plate 19, so as to prevent impurities from docking on the slow flow plate 19 to the greatest extent, and improve the convenience of impurity cleaning.

[0034] By providing the rubber sleeve 22, the sound generated when the knocking ball 21 knocks against the slow flow plate 19 is reduced, thereby reducing the noise of the device and improving the effect of the use of the device.

[0035] Working principle: When treating the wastewater generated in the city, the water inlet 2 is used to transport the wastewater to the inside of the treatment box 1, and then the wastewater contacts the diverter plate 4. Since the uppermost and lowermost through grooves 5 are closed, the wastewater will pass through the gap between the diverter plate 4 and the treatment box 1 and the through groove 5 in the middle. When the wastewater passes through, it is filtered by two filter plates 6 and then discharged through the water outlet 3. After the filter plates 6 have worked for a long time, the two filter plates 6 are controlled by the cleaning structure to rise and fall respectively, and clean them. After the wastewater enters the treatment box 1, it contacts the slow flow plate 19, and the slow flow plate 19 reduces the flow rate of the wastewater. Then the wastewater enters the diverter plate 4 for filtration. During cleaning, the motor 7 synchronously drives the worm 8 to rotate, and the worm 8 synchronously drives the worm wheel 10 to rotate. The worm gear 10 synchronously drives the rotating rod 9 to rotate, and the rotating rod 9 synchronously drives the gear 11 to rotate. The rotation of the gear 11 causes the two tooth plates 12 to rise and fall respectively, and the tooth plate 12 drives the filter plate 6 to move. The filter plate 6 rises so that part of the filter screen located in the middle through groove 5 enters the interior of the upper through groove 5, and part of the filter screen located between the diverter plate 4 and the bottom wall of the treatment box 1 enters the interior of the lower through groove 5. The filter plate 6 descends so that part of the filter screen located in the upper through groove 5 and the lower through groove 5 enters the middle through groove 5 and the lower gap respectively. Then, the water pump 16 is used to transport water to the water pipe 17. The water pipe 17 transports the water flow to the interior of the upper and lower through grooves 5. The reverse impact of the water flow washes down the residue and dirt on the filter screen and discharges it through the sewage outlet 13.

[0036] When the driving motor 27 is started, the driving motor 27 drives the half gear 26 to rotate, and since the half gear 26 is meshed with the rack 25, the rack 25 and the lifting plate 23 are driven to move downward, so that the knocking ball 21 and the rubber sleeve 22 are no longer in contact with the inner wall of the slow flow plate 19, and the lifting plate 23 is made to slide on the two fixed limiting rods 20 and squeeze the two reset springs 28. Since there are only half teeth on the half gear 26, as the driving motor 27 drives the half gear 26 to continue to rotate, the half gear 26 is no longer meshed with the rack 25, and the lifting plate 23, the knocking ball 21 and the rubber sleeve 22 are reset by the elastic force of the reset spring 28, so that the knocking ball 21 and the rubber sleeve 22 knock on the inner wall of the slow flow plate 19, so that the slow flow plate 19 vibrates, which makes it easier to shake off the impurities on the slow flow plate 19.

[0037] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
