Two mounting grooves 33 are symmetrically arranged on the collection box 31, and two screws 34 are respectively fixedly installed on the two mounting grooves. In the groove 33, two threaded rings 35 are respectively threadedly installed on the two screws 34, the first filter screen 36 is arranged inside the collection box 31, the slot 37 is opened inside the first filter screen 36, the two side pieces 38 are symmetrically installed on the side wall of the first filter screen 36, the two side pieces 38 are respectively sleeved on the two screws 34, the second filter screen 32 is evenly and equidistantly fixedly installed inside the collection box 31, the side wall of the filter cartridge 11 is fixedly provided with a water outlet pipe 12, the inner wall of the filter cartridge 11 is symmetrically fixedly installed with a first arc plate 13, and the upper ends of the two first arc plates 13 are A spring 14 is fixedly installed, and a second arc plate 15 is fixedly installed on the upper ends of the two springs 14. The two second arc plates 15 are both fitted with the collection box 31. A cylinder cover 21 is clamped on the top of the filter cylinder 11. A water injection port 22 is opened inside the cylinder cover 21. An arc groove 23 is opened in the inner wall of the water injection port 22. A cover plate 24 is slidably installed inside the water injection port 22. A slide bar 25 is fixedly installed on the side wall of the cover plate 24. The slide bar 25 is slidably installed in the arc groove 23. A drive motor 26 is fixedly installed at the center of the cylinder cover 21. The output of the drive motor 26 A rotating shaft 27 is installed at the end, and a connecting block 28 is symmetrically fixedly installed on the side wall of the rotating shaft 27. The two connecting blocks 28 are inserted into the slots 37. When the first filter screen 36 needs to be disassembled, the cylinder cover 21 together with the driving motor 26, the rotating shaft 27 and the connecting block 28 can be removed from the filter cylinder 11, and then the collection box 31 and the first filter screen 36 can be taken out, and then the two threaded rings 35 can be removed from the two screw rods 34, and then the slot 37 together with the two side pieces 38 can be removed from the screw rods 34, so that the device is more convenient to install and disassemble when in use;When in use, the slide bar 25 can be pulled inside the arc groove 23 first, and the movement of the slide bar 25 will drive the cover plate 24 to move inside the water injection port 22. When the cover plate 24 slides into the water injection port 22, the water injection port 22 will be opened, and waste water can be injected into the filter cartridge 11 through the water injection port 22. When injecting water, the drive motor 26 can be started, and the drive motor 26 will drive the shaft 27 to rotate, and the shaft 27 will drive the connecting block 28 to rotate. At this time, the rotation of the connecting block 28 will drive the first filter screen 36 to rotate, and the first filter screen 36 will rotate. The collection box 31 will be driven to rotate accordingly. At this time, part of the sewage falling on the first filter screen 36 will be filtered and fall, and the other part will fall into the collection box 31. Then, the sewage will be filtered by the second filter screen 32 and fall into the filter cylinder 11. The impurities will be left in the collection box 31. Since the first filter screen 36 is in a rotating state, the impurities adhered to it will be thrown into the collection box 31 for collection during its rotation, so that the first filter screen 36 does not need to be cleaned frequently when the device is used, and the first filter screen 36 is not easy to be blocked, which enhances the use effect of the device. ;

[0025] In view of the problems existing in the prior art, the utility model provides a domestic wastewater filtering device. When the device is in use, the first filter screen 36 does not need to be frequently cleaned, and the first filter screen 36 is not easily clogged, thereby enhancing the use effect of the device.

[0026] Working principle:

[0027] In the first step, when in use, the slide bar 25 can be pulled inside the arc groove 23, and the movement of the slide bar 25 will drive the cover plate 24 to move inside the water injection port 22. When the cover plate 24 slides into the water injection port 22, the water injection port 22 will be opened, and waste water can be injected into the filter cartridge 11 through the water injection port 22, so that the water injection port of the device can be closed when not in use, effectively preventing dust from entering the filter cartridge 11. When water is injected, the drive motor 26 can be started, and the drive motor 26 will drive the rotating shaft 27 to rotate, and the rotating shaft 27 will drive the connecting block 28 to rotate. At this time, the rotation of the connecting block 28 will bring The first filter screen 36 rotates accordingly, and the first filter screen 36 drives the collection box 31 to rotate accordingly. At this time, part of the sewage falling on the first filter screen 36 will be filtered and fall, and the other part will fall into the collection box 31. Then the sewage is filtered by the second filter screen 32 and falls into the filter cylinder 11. Impurities will be left in the collection box 31. Since the first filter screen 36 is in a rotating state, the impurities adhered to it will be thrown into the collection box 31 for collection during its rotation, so that the first filter screen 36 does not need to be cleaned frequently when the device is in use, and the first filter screen 36 is not easy to be blocked, thereby enhancing the use effect of the device.

[0028] In the second step, when the first filter screen 36 needs to be disassembled, the barrel cover 21 together with the drive motor 26, the rotating shaft 27 and the connecting block 28 can be removed from the filter barrel 11. At this time, the second arc plate 15 will lose the pressure effect, and the spring 14 will restore the deformation. Then the collection box 31 and the first filter screen 36 can be taken out, and then the two threaded rings 35 can be removed from the two screws 34, and then the slot 37 together with the two side pieces 38 can be removed from the screw 34, so that the device is more convenient to install and disassemble when in use.

[0029] 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.
