[0023] In the utility model, in order to make it more convenient for personnel to install the filter screen plate 6, the angle formed by the inner side surface of the clamping block 12 and the horizontal plane is set to forty-five degrees, and the width of the clamping block 12 is twenty-five millimeters, so that the clamping block 12 can move outward when squeezed by the force-bearing plate 7, thereby making it more convenient for personnel to install the filter screen plate 6.

[0024] In the present invention, in order to make people feel more comfortable when touching the handle 8, the outer surface of the handle 8 is wrapped with a rubber layer with a thickness of three millimeters, and the cross-sectional shape of the handle 8 is circular, which can increase the contact area of ​​the hand on the handle 8, thereby making people feel more comfortable when touching the handle 8.

[0026] In the present utility model, in order to prevent the convex slider 11 from malfunctioning when sliding in the convex slide groove 10, the length of the convex slider 11 is set to 55 mm, and the size of the convex slider 11 is adapted to the size of the inner wall of the convex slide groove 10, so that the convex slider 11 is not easily stuck when sliding in the convex slide groove 10, thereby preventing the convex slider 11 from malfunctioning when sliding in the convex slide groove 10.

[0027] Working principle: when in use, the sewage to be treated is poured into the treatment box 1 through the water inlet pipe 2. At this time, the sewage will fall downward and pass through the filter screen plate 6, so that the filter screen plate 6 filters the sewage, so that the device purifies the sewage, and the treated sewage continues to fall downward and is discharged from the treatment box 1 from the drain pipe 3, so that the device completes the treatment of the sewage. When the filter screen plate 6 needs to be replaced or cleaned, it is only necessary to press the toggle plates 13 on both sides outward to allow the convex sliding block 11 to overcome the elastic force of the clamping spring 15 and move outward along the convex sliding groove 10, and allow the clamping block 12 to move outward and disengage from the clamping groove 9 at the same time, so that the plug-in frame 5 is no longer fixed. At this time, under the elastic force of the unloading spring 19, the push-out piece 18 will move forward along the unloading telescopic column 17, allowing the push-out piece 18 to push the force-bearing plate 7 to move forward, so that the plug-in frame 5 moves forward along the plug-in groove 4, and the plug-in frame 5 pops out from the plug-in groove 4. The impurities on the plate 6 will also be taken out together with the plug-in frame 5, so that the filter plate 6 is removed from the device. When the filter plate 6 needs to be installed, it is only necessary to align the plug-in frame 5 with the plug-in slot 4 and insert it, and then push the force-bearing plate 7 to the rear side, so that the plug-in frame 5 moves to the rear side along the plug-in slot 4. During this process, the force-bearing plate 7 will squeeze the push-out piece 18, so that the push-out piece 18 overcomes the unloading spring 19 and moves to the rear side along the unloading telescopic column 17, and at the same time, the unloading spring 19 accumulates a certain amount of force. When the force-bearing plate 7 continues to move toward the rear side and squeezes the clamping block 12, the clamping block 12 will overcome the elastic force of the clamping spring 15 and move outward along the convex slide groove 10, so that the clamping block 12 no longer blocks the force-bearing plate 7. When the force-bearing plate 7 continues to move toward the rear side and aligns the clamping groove 9 with the clamping block 12, the clamping block 12 will move inward under the elastic force of the clamping spring 15, so that the clamping block 12 is inserted into the clamping groove 9, thereby fixing the filter screen plate 6 in the device.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
