The collection tank 4 is used to collect these wastes, which is convenient for workers to collect these wastes for the next step of processing. The angle between the filter screen 3 and the horizontal plane is about 5-15 degrees. The lower part of the filter screen 3 contacts the rear inner wall of the box body 1, and the upper part of the filter screen 3 contacts the edge of the guide plate 2. The role of setting a slope for the filter screen 3 is to prevent the sewage that has not passed through the filter screen 3 from flowing out of the sewage outlet 1-1 when there is a lot of sewage on the filter screen 3. The top of the box body 1 is provided with a water inlet pipe 11, and the outlet of the water inlet pipe 11 is located just above the center of the filter screen 3. Sewage can enter the box body 1 from the water inlet pipe 11;

[0022] A slide groove 1-3 is provided on each of the left and right inner walls of the box body 1. The slide groove 1-3 is located above the filter screen 3 and parallel to the top of the box body 1. The two slide grooves 1-3 are symmetrical about the central axis of the box body 1. A cleaning structure 5 is slidably installed between the slide grooves 1-3 on the left and right sides. The cleaning structure 5 can slide back and forth in the box body 1 along the slide groove 1-3;

[0023] Two screw rods 6 are rotatably installed between the front and rear inner walls of the box body 1, and the two screw rods 6 are respectively close to the left and right inner walls of the box body 1 and are parallel to the slide groove 1-3. Nuts 7 are provided on the two screw rods 6, and the two nuts are fixed to the cleaning structure 5. Sprockets are installed on the two screw rods 6, and the two sprockets are connected by a chain 9. A motor 8 is installed on the box body 1, and the output shaft of the motor 8 is connected to one of the screw rods 6. The motor 8 can drive the screw rod 6 connected to it to rotate, and then drive the other screw rod 6 to rotate through the chain 9. By controlling the rotation direction of the screw rod 6 and cooperating with the nut 7, the cleaning structure 5 can be controlled to move back and forth in the box body 1.

[0024] See also Figure 4 The cleaning structure 5 includes a bottom plate 51, and a slider 52 is installed on each side of the bottom plate 51. The two sliders are respectively matched with the slide grooves 1-3 on the left and right inner walls of the box body 1. Two nuts 7 are respectively fixed on the two sliders 52. Four slide rods 53 are slidably installed on the bottom plate 51. A brush plate 54 is installed at the bottom of the slide rod 53. Springs 55 are sleeved on the four slide rods 53. The springs 55 are pressed between the bottom plate 51 and the brush plate 54. Brushes 56 are installed at the bottom of the brush plate 54. The brushes 56 must always be pressed on the filter screen 3 under the action of the springs 55. When the cleaning structure 5 moves, the brushes 54 can push the waste filtered out of the filter screen 3 to the sewage outlet 1-1.

[0025] See also Figure 2 A slope 10 is provided at the bottom of the inner cavity of the box body 1, the lower part of the slope 10 contacts the rear inner wall of the box body 1, and the upper part of the slope 10 contacts the front inner wall of the box body 1. A drain port 1-2 is provided on the side wall of the box body 1, and the drain port 1-2 is located at the bottom of the slope 10. After passing through the filter screen 3, the sewage will fall to the slope 10, then slide down the slope 10, and finally be discharged from the drain port 1-2.

[0026] The working principle and use process of the utility model are as follows: when the sewage purification device is in use, the sewage to be treated is added into the box body 1 from the water inlet pipe 11. When the sewage passes through the filter screen 3, the solid waste will be left on the filter screen 3. The sewage filtered by the filter screen 3 will fall to the slope 10, and then slide down along the slope 10 and be discharged from the drain outlet 1-2. When no sewage enters the box body 1, the motor 8 is started, and the motor 8 drives the screw 6 connected to it to rotate, and then drives another screw 6 to rotate through the chain 9, thereby driving the cleaning structure 5 to move toward the sewage outlet 1-1 until the slider 52 of the cleaning structure 5 moves to the front end of the slide groove 1-3, and then the motor 8 reverses to control the cleaning structure 5 to return to its original position. During the movement of the cleaning structure 5 toward the sewage outlet 1-1, the brush 56 will push the waste filtered out of the filter screen 3 to the sewage outlet 1-1 until the waste is pushed to the guide plate 2 and discharged from the sewage outlet 1-1 along the guide plate 2. The waste discharged from the sewage outlet 1-1 will eventually fall into the collecting tank 4.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
