All the technical means mentioned in this application document adopt the same technical means in this prior art, and this technical means will not be repeated here one by one.

[0038] like Figures 1 to 9 As shown, the cleaning assembly includes a first cleaning plate 11 arranged at the top of the filter 5, and the interior of the first cleaning plate 11 is evenly installed with slag suction pipes 12, the top of the first cleaning plate 11 is rotatably connected with a first connecting pipe 13, and the end of the first connecting pipe 13 away from the first cleaning plate 11 is embedded in the interior of the fixed cabin 1, and the bottom end of the first connecting pipe 13 is fixedly connected with a slag discharge pipe 14, and the interior of the first connecting pipe 13 is slidably installed with a first piston 15, and the internal thread of the first piston 15 is connected with a first reciprocating screw rod 16, and the first reciprocating screw rod 16 is rotatably installed in the interior of the fixed cabin 1 through a power component.

[0039] The outer walls of the first connecting pipe 13 and the slag discharge pipe 14 are both installed with a one-way valve;

[0042] When wastewater enters the feed pipe 3, the water wheel blades 6 are driven to rotate. The rotation of the water wheel blades 6 drives the first rotating shaft 7 to rotate. The rotation of the first rotating shaft 7 drives the first gear 8 to rotate. When the first gear 8 rotates, the second gear 17 is driven to rotate through the chain 10, thereby providing power for the cleaning component. The power is provided by the flow of wastewater, saving operating costs and reducing manual intervention.

[0043] like Figures 1 to 6As shown, a slag collecting box 18 is provided below the slag discharge pipe 14 , a guide pipe 19 is provided at the bottom end of the slag collecting box 18 , and one end of the guide pipe 19 away from the slag collecting box 18 is connected to the feed pipe 3 .

[0044] The bottom end of the slag collecting box 18 is evenly provided with through holes;

[0045] The impurities sucked away from the top of the filter screen 5 are collected by the slag collecting box 18, and part of the waste water contained in the impurities is filtered and guided to the feed pipe 3 through the guide pipe 19 to reduce waste.

[0046] like Figure 1 and Figure 2 As shown, the slag collecting box 18 is slidably installed inside the fixed cabin 1.

[0047] The slag collecting box 18 can be slid and removed from below the slag discharging pipe 14, and then taken out for easy maintenance.

[0048] like Figures 1 to 11 As shown, the auxiliary cleaning component includes a second cleaning plate 21 arranged at the bottom end of the filter 5, and a water spray pipe 22 is evenly installed inside the second cleaning plate 21. The bottom end of the second cleaning plate 21 is rotatably connected to a third connecting pipe 23, and one end of the third connecting pipe 23 away from the second cleaning plate 21 is embedded in the fixed cabin 1, and the bottom end of the third connecting pipe 23 is fixedly connected to a water suction pipe 24, and one end of the water suction pipe 24 is embedded in the feed pipe 3. A second piston 25 is slidably installed inside the third connecting pipe 23, and the internal thread of the second piston 25 is connected to a second reciprocating screw 26, and the bottom end of the second reciprocating screw 26 is fixedly installed with a third gear 27, and the third gear 27 is meshingly installed inside the chain 10.

[0049] A groove is formed at the top of the mounting plate 9, in which a portion of water can be accumulated, and one end of the guide pipe 19 and the water suction pipe 24 are both located in the groove;

[0050] The outer walls of the third connecting pipe 23 and the water suction pipe 24 are both installed with a one-way valve;

[0051] When the chain 10 rotates, it drives the third gear 27 to rotate, and the rotation of the third gear 27 drives the rotation of the second reciprocating screw 26. The rotation of the second reciprocating screw 26 drives the second piston 25 to move up and down reciprocatingly. The water inside the mounting plate 9 is sucked through the suction pipe 24 and then transported to the inside of the second cleaning plate 21 through the third connecting pipe 23, and finally sprayed from the water spray pipe 22 to the bottom of the filter 5. Backwashing the bottom of the filter 5 can more effectively remove suspended matter or particulate impurities inside the filter 5, thereby ensuring the use effect of the filter 5.

[0052] like Figure 4 , Figure 5 , Figure 6 and Figure 8As shown, the second cleaning plate 21 and the first cleaning plate 11 are symmetrically arranged, and both the second cleaning plate 21 and the first cleaning plate 11 are rotatably installed inside the feed pipe 3 through a rotating assembly, and a control assembly is arranged inside the second cleaning plate 21.

[0053] By cooperating with the cleaning component and the auxiliary cleaning component, the first cleaning plate 11 absorbs residues when the second cleaning plate 21 sprays water. The two cooperate to efficiently remove impurities in the filter screen 5, thereby improving the cleaning effect of the filter screen 5.

[0054] like Figures 5 to 8 As shown, the rotating assembly includes an annular gear 37 fixedly mounted on the outer walls of the second cleaning plate 21 and the first cleaning plate 11, one side of the annular gear 37 is meshingly connected with a fourth gear 38, a second rotating shaft 39 is fixedly mounted inside the fourth gear 38, a fifth gear 40 is fixedly connected to the bottom end of the second rotating shaft 39, and the fifth gear 40 is meshingly mounted inside the chain 10.

[0055] When the chain 10 rotates, the fifth gear 40 is driven to rotate, the rotation of the fifth gear 40 drives the second rotating shaft 39 to rotate, the rotation of the second rotating shaft 39 drives the fourth gear 38 to rotate, and the rotation of the fourth gear 38 drives the ring gear 37 to rotate, so that the first cleaning plate 11 and the second cleaning plate 21 rotate at the top and bottom of the filter 5 at the same time to ensure comprehensive cleaning.

[0056] like Fig.10 and Fig.11 As shown, the control component includes a fifth connecting tube 30 arranged inside the second cleaning plate 21, the top end of the fifth connecting tube 30 is fixedly connected to the fourth connecting tube 29, the side walls of the fourth connecting tube 29 are evenly installed with air bags 28, the air bags 28 are arranged inside the water spray pipe 22, and one end of the fifth connecting tube 30 is provided with an air storage chamber 31, a push plate 32 is slidably installed inside the air storage chamber 31, a slider 34 is fixedly installed on the side wall of the push plate 32, the slider 34 is slidably installed on the inner wall of the slide groove 35, the slide groove 35 is opened on the inner wall of the feed pipe 3, and a guide block 36 is fixedly installed on the inner wall of the slide groove 35.

[0057] When the second cleaning plate 21 rotates, the slider 34 slides in the inner wall of the slide groove 35. When the slider 34 contacts the guide block 36, it is forced to slide into the interior of the second cleaning plate 21. The movement of the slider 34 drives the push plate 32 to slide into the air storage chamber 31, squeezing the internal gas of the air storage chamber 31 into the air bag 28 through the fifth connecting pipe 30 and the fourth connecting pipe 29, so that the air bag 28 expands, the outlet of the water spray pipe 22 becomes smaller, and the pressure of the water spray becomes larger, thereby increasing the pressure of the impact on the filter 5 to improve the cleaning effect.

[0058] like Fig.11 As shown, a tension spring 33 is installed on one side of the push plate 32 , and the tension spring 33 is arranged on the outer wall of the sliding block 34 .

[0059] When the slider 34 contacts the guide block 36 and slides into the second cleaning plate 21, the tension spring 33 is deformed and stores elastic potential energy.

[0060] When the slider 34 slides and separates from the guide block 36, the elastic potential energy is released by the tension spring 33 to move the slider 34 back to its original position, thereby reducing the air pressure in the airbag 28 and restoring the outlet of the water spray pipe 22 to a normal size, so that the water pressure sprayed from the water spray pipe 22 changes intermittently, thereby preventing the filter screen 5 from being completely blocked by impurities during the backwashing process, and ensuring that the flushing water flow can continue to pass through the filter screen 5 to achieve a better cleaning effect.

[0061] Working principle and usage process:

[0062] When the low-temperature evaporator is in use, the staff manually pours the waste water into the feed bin 2 and manually starts the power switch. At this time, the waste water is filtered through the filter screen 5 when it enters the feed pipe 3 under the action of the conveying device such as the water pump. The filtered waste water is then sent to the interior of the distillation kettle 4 through the feed pipe 3 for treatment;

[0063] When the filtered wastewater flows downward, the water wheel blade 6 is driven to rotate, and the rotation of the water wheel blade 6 drives the rotation of the first rotating shaft 7, and the rotation of the first rotating shaft 7 drives the rotation of the first gear 8. When the first gear 8 rotates, the second gear 17, the third gear 27 and the fifth gear 40 are driven to rotate through the chain 10;

[0064] The rotation of the second gear 17 drives the rotation of the first reciprocating screw 16, and the rotation of the first reciprocating screw 16 drives the first piston 15 to move up and down reciprocatingly, and the impurities on the top of the filter screen 5 are sucked through the slag suction pipe 12 via the first connecting pipe 13, and then transmitted to the inside of the slag collecting box 18 through the slag discharge pipe 14. After the slag collecting box 18 filters the impurities, the water inside is redirected back to the feed pipe 3 through the guide pipe 19;

[0065] The rotation of the third gear 27 drives the rotation of the second reciprocating screw 26, and the rotation of the second reciprocating screw 26 drives the second piston 25 to move up and down reciprocatingly, and the water inside the mounting plate 9 is sucked through the water suction pipe 24 and then transported to the inside of the second cleaning plate 21 through the third connecting pipe 23, and finally sprayed from the water spray pipe 22 to the bottom of the filter screen 5, so as to backwash the bottom of the filter screen 5;

[0066] The rotation of the fifth gear 40 drives the second rotating shaft 39 to rotate, the rotation of the second rotating shaft 39 drives the fourth gear 38 to rotate, the rotation of the fourth gear 38 drives the ring gear 37 to rotate, so that the first cleaning plate 11 and the second cleaning plate 21 rotate simultaneously;

[0067] When the second cleaning plate 21 rotates, it drives the slider 34 to slide inside the slide groove 35. When the slider 34 contacts the guide block 36, it is forced to slide into the second cleaning plate 21. The movement of the slider 34 drives the push plate 32 to slide into the air storage chamber 31, squeezing the internal gas of the air storage chamber 31 into the air bag 28 through the fifth connecting pipe 30 and the fourth connecting pipe 29, so that the air bag 28 expands, the outlet of the water spray pipe 22 becomes smaller, and the pressure of the water spray becomes larger. After the slider 34 slides and separates from the guide block 36, the elastic potential energy is released by the tension spring 33 to move the slider 34 to reset, thereby reducing the air pressure in the air bag 28, and the outlet of the water spray pipe 22 returns to its normal size, so that the water pressure sprayed from the water spray pipe 22 changes intermittently, so that the device works continuously.
