It can filter out impurities such as mud, rust, algae, and bacteria from the water, achieving a higher level of water purity. A pressure plate 14 is fixedly connected to the top of the filter screen 7, and the bottom of the cover 2...
[0036] The end is equipped with a cleaning mechanism, and the bottom end of the connecting rod 15 is equipped with a reciprocating component. The cleaning mechanism includes a gear 5, and a scraper 6 meshes with the outer wall of the gear 5. A rectangular strip is provided at the upper end of the scraper 6, and the rectangular strip is provided with teeth that match the gear 5. The gear 5 is rotatably connected to the bottom end of the box cover 2. The box cover 2 has a slot corresponding to the gear 5, so that the gear 5 can rotate without obstruction.
[0037] Referring to Figures 1, 5, and 6, the reciprocating assembly includes a rotating rod 10. A slider 13 is mounted on the outer wall of the rotating rod 10. The lower end of the rotating rod 10 is threaded. The slider 13 has a texture matching the rotating rod 10, allowing it to reciprocate on the rotating rod 10. A moving ring 12 is fixedly connected to the top of the slider 13. A stirring rod 11 is rotatably connected through the inner wall of the moving ring 12. The stirring rod 11 has an annular groove to prevent obstruction during rotation. The rotating rod 10 is fixedly connected to the bottom end of the connecting rod 15. The stirring rod 11 is slidably connected to the outer wall of the rotating rod 10. A protrusion is provided on the rotating rod 10, allowing the stirring rod 11 to move vertically while rotating with the rotating rod 10. The slider 13 is slidably connected to the inner wall of the processing tank 1. A guide rod is mounted on the slider 13. A slot corresponding to the guide rod is provided on the processing tank 1. The guide rod guides the slider 13. The rotating rod 10 serves as a guide and is rotatably connected to the inner wall of the processing box 1. The processing box 1 has a slot corresponding to the rotating rod 10 so that the rotating rod 10 can rotate without being obstructed.
[0038] Reference Figures 2-4 The inner wall of the front end of the processing box 1 is fixedly connected to one end of the movable spring 9, and the other end of the movable spring 9 is fixedly connected to the outer wall of the filter screen 7. When the filter screen 7 moves forward, the movable spring 9 is stretched. When resetting, the elastic force of the movable spring 9 carries the filter screen 7 back to its original position. The scraper 6 is slidably connected to the bottom end of the box cover 2. The box cover 2 has a slot corresponding to the rectangular strip on the scraper 6, which allows the scraper 6 to move back and forth. The bottom end of the scraper 6 contacts the inner wall of the processing box 1. The outer wall of the gear 5 meshes with the left side wall of the filter screen 7. The filter screen 7 has teeth that match the gear 5. Power can be transmitted to the gear 5 through the filter screen 7. The filter screen 7 is slidably connected to the right side wall of the fixed plate 8. The filter screen 7 has rectangular blocks. The fixed plate 8 has a slot corresponding to the rectangular blocks, which allows the filter screen 7 to move back and forth. The filter screen 7 is slidably connected to the inner wall of the processing box 1.
[0039] On the inner wall, the processing box 1 has a slot corresponding to the filter screen 7, allowing the filter screen 7 to move back and forth. The extrusion plate 14 passes through and is slidably connected to the inner wall of the box cover 2. The box cover 2 has a slot corresponding to the extrusion plate 14, allowing the extrusion plate 14 to move back and forth. The outer wall of the cam 4 contacts the outer wall of the extrusion plate 14, and the cam 4 will extrude the extrusion plate 14, causing the extrusion plate 14 to move forward. The connecting rod 15 passes through and is rotatably connected to the inner wall of the box cover 2. The box cover 2 has a slot corresponding to the connecting rod 15.
[0040] Working principle: When sewage needs to be treated, the operator can turn on motor 3. Motor 3 will rotate connecting rod 15 and cam 4. Cam 4 will squeeze and press extrusion plate 14, causing extrusion plate 14 to move filter screen 7 forward and stretch movable spring 9. During the forward movement of filter screen 7, front fixed plate 8 will clean the impurities on the front half of the left side wall of filter screen 7. At the same time, filter screen 7 will drive gear 5 to rotate. Gear 5 will transmit power to scraper 6, causing scraper 6 to move backward. Scraper 6 will clean the impurities on the rear half of the left side wall of filter screen 7 to prevent impurities from clogging filter screen 7. When cam 4 is no longer in contact with extrusion plate 14, the elasticity of movable spring 9 will move filter screen 7 to the initial position. At this time, filter screen 7 will transmit power to gear 5, and gear 5 will move scraper 6 forward to the initial position. When cam 4 contacts extrusion plate 14 again, filter screen 7 will repeat the above trajectory movement.
[0041] After the initial filtration of wastewater is completed, the staff can add disinfectant to the treatment tank 1. At this time, the connecting rod 15 will rotate the rotating rod 10, which in turn will rotate the stirring rod 11. Simultaneously, the slider 13 on the rotating rod 10 will move upward along with the moving ring 12 and the stirring rod 11. The stirring rod 11 continues to rotate, ensuring thorough mixing of the wastewater and disinfectant. When the slider 13 reaches the uppermost end of the thread on the rotating rod 10, it will change its trajectory and move downward, carrying the moving ring 12 and the stirring rod 11 downward. The stirring rod 11 will then mix the lower layer of wastewater and disinfectant. When the slider 13 reaches the lowermost end of the thread, it will change its trajectory and continue to repeat the above movement. If further treatment of the wastewater is required, simply repeat the above steps.
[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
