[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments.

The heating assembly installed on the housing 12, the knocking rod 24 knocks on the screen plate 29, causing the screen plate 29 to vibrate. The first motor 213 drives the lever 23 to rotate, and the lever 23 drives the knocking rod 24 to contact the screen plate 29. The hydraulic cylinder 14 transports wastewater from the third conveying pipe 17 into the filter housing 2. When the wastewater passes through the connecting rod 28, the impurities in the wastewater are blocked by the screen plate 29. The lever 23 and the knocking rod 24 are provided with protrusions, which are used to drive the knocking rod 24 to rotate when the lever 23 rotates. The knocking rod 24 knocks on the screen plate 29, causing the impurities on the screen plate 29 to fall onto the screen mesh 210 to filter out the impurities in the wastewater. The screen mesh 210 starts to collect the impurities in the wastewater. Impurities fall onto the screen mesh 210, but the wastewater can still flow out from its surroundings.

[0017] Please see Figures 1-4In this embodiment, a tension spring 26 is fixedly connected between the filter shell 2 and the knocking rod 24. A limiting rod 27 is fixedly connected to the filter shell 2. Sealing caps 211 are respectively connected to the shell 12 and the filter shell 2. A slide rail 212 is fixedly connected between the shell 12 and the filter shell 2. A pull rod is provided on one side of the screen 210. The screen 210 is pulled by the pull rod to slide on the slide rail 212. The tension spring 26 plays a role in resetting the knocking rod 24. The limiting rod 27 plays a role in limiting the screen plate 29 and the knocking rod 24. By pulling the pull rod on the screen 210, the screen 210 can be easily removed from the filter shell 2, and the screen 210 can be cleaned. An insulation shell 13 is fixedly connected to the base 1. A first water supply pipe 15 is fixedly connected to the insulation shell 13. A second water supply pipe 16 is provided between the insulation shell 13 and the hydraulic cylinder 14. A third delivery pipe 17 is provided between the hydraulic cylinder 14 and the shell 12. Valves 18 are respectively provided on the second water supply pipe 16 and the third delivery pipe 17. The inner wall of the insulation shell 13 is filled with a material with poor thermal conductivity, such as foam plastic and organic materials, to prevent the temperature of the wastewater from dropping too quickly. The valve 18 is a one-way valve. The wastewater in the insulation shell 13 is open when flowing to the hydraulic cylinder 14 and closed when flowing in the opposite direction. The wastewater in the hydraulic cylinder 14 is open when flowing to the filter shell 2 and closed when flowing in the opposite direction, in order to prevent wastewater backflow. A cover plate is provided on the top of both the insulation shell 13 and the hydraulic cylinder 14.

[0018] Please see Figure 2 , Figure 5 In this embodiment, the power assembly includes a second motor 4 fixedly connected to the hydraulic cylinder 14, a drive wheel 42 fixedly connected to the output end of the second motor 4, a threaded rod 47 rotatably connected to the hydraulic cylinder 14, a driven wheel 44 fixedly connected to the threaded rod 47, a belt 43 drivingly connected between the drive wheel 42 and the driven wheel 44, a movable plate 45 threadedly connected to the threaded rod 47, and a filter screen 46 disposed on the movable plate 45. The movable plate 45 moves upward to transport wastewater in the hydraulic cylinder 14 to the housing 12 through the third conveying pipe 17, and the movable plate 45 moves downward to draw wastewater in the heat preservation shell 13 into the hydraulic cylinder 14 through the second water supply pipe 16. The second motor 4 rotates the threaded rod 47 to move the movable plate 45 up and down. The up and down movement of the movable plate 45 enables the device to suck in and transport wastewater, allowing the wastewater to circulate within the device. A gap is provided between the filter screen 46 and the threaded rod 47. The filter screen 46 has many holes. Larger debris in the wastewater falls into the gap through the holes under the influence of gravity and the upward movement of the movable plate 45. The filter screen 46 can be removed by removing the cover plate on the hydraulic cylinder 14, and the gap can be cleaned. The hydraulic cylinder 14 is equipped with a guide rail, and the movable plate 45 has a sliding groove at the corresponding position on the guide rail. The movable plate 45 slides on the guide rail through the sliding groove. When the threaded rod 47 rotates, the guide rail prevents the movable plate 45 from rotating with the threaded rod 47.

[0019] Please see Figure 3, Figure 6 In this embodiment, the heating assembly includes a heating chamber 32 fixedly connected to the housing 12, a guide pipe 3 fixedly connected between the filter housing 2 and the heating chamber 32, a heat-conducting pipe 33 disposed in the heating chamber 32, a plug 34 disposed on the heating chamber 32, and a water outlet pipe 35 fixedly connected to the heating chamber 32. Wastewater flows into the heat-conducting pipe 33 through the guide pipe 3. The heat-conducting pipe 33 heats the cold water injected into the heating chamber 32. The guide pipe 3 transports the filtered wastewater into the heat-conducting pipe 33. The heat-conducting pipe 33 is made of a heat-conducting material, such as copper and silver. The wastewater with temperature heats the heat-conducting pipe 33. The plug 34 is removed to pour cold water into the heating chamber 32. The inner wall of the heating chamber 32 is filled with a material with poor thermal conductivity, such as foam plastic and organic material, to prevent heat loss. Due to the characteristic of high temperature flowing to low temperature, the heated heat-conducting pipe 33 heats the cold water in the heating chamber 32. The heating chamber 32 is provided with a water inlet, and a plug 34 is provided on the water inlet. The plug 34 is used to seal the heating chamber 32 to prevent heat loss.

[0020] During operation, the cap 34 is removed, cold water to be heated is poured into the heating chamber 32, and then wastewater with temperature is injected into the insulation shell 13. The second motor 4 is started, which drives the drive wheel 42 to rotate. The drive wheel 42 transmits power to the driven wheel 44 through the belt 43. The driven wheel 44 drives the threaded rod 47 to rotate, and the threaded rod 47 causes the movable plate 45 to move up and down. The movement of the movable plate 45 causes the filter screen 46 to move. When the movable plate 45 moves downward, the wastewater in the insulation shell 13 is sucked into the hydraulic cylinder 14 through the second water supply pipe 16. When the movable plate 45 moves upward, the wastewater is passed through... The third conveying pipe 17 delivers wastewater into the filter shell 2. Valve 18 prevents wastewater from flowing back into the insulation shell 13. When the wastewater passes through the sieve plate 29, the impurities in the wastewater are blocked by the sieve plate 29. The first motor 213 is started, and the first motor 213 drives the lever 23 to rotate. The lever 23 drives the knocking rod 24 to rotate. The knocking rod 24 knocks the sieve plate 29. The impurities on the sieve plate 29 fall onto the screen 210 due to vibration. The filtered wastewater is delivered to the heat-conducting pipe 33 through the guide pipe 3. The heat-conducting pipe 33 is heated by the wastewater, which raises the temperature of the heat-conducting pipe 33. The heat-conducting pipe 33 then heats the cold water in the heating chamber 32.

[0021] Through the above steps, the first motor 213 drives the lever 23 to rotate, the lever 23 drives the knocking rod 24 to rotate, and the knocking rod 24 knocks the screen plate 29. The debris on the screen plate 29 is knocked off the screen 210 by the knocking rod 24. This solves the problem that the filter screen is prone to clogging and contamination over time, and that there is no automatic cleaning function, which requires the staff to clean the filter screen frequently, resulting in poor operability, wasting a lot of time, and reducing work efficiency.
