[0009] Furthermore, a sewage discharge pipe is arranged below an outer wall of one side of the sewage collection tank body, and a valve body is arranged on the sewage discharge pipe.

[0010] Furthermore, a threaded hole is provided at the center of the outer wall of the movable plate, and an external thread is provided on the outer wall of the rotating shaft. The external thread on the outer wall of the rotating shaft and the threaded hole on the movable plate are threadedly engaged with each other.

[0015] By means of the above technical solution, the utility model provides a sewage purification device, which has at least the following beneficial effects:

[0016] 1. The utility model is provided with a series of coordinated structures. When the utility model filters solid impurities from sewage, the staff makes the sewage fall onto the filter plate from above the filter plate. The filter holes on the filter plate filter the sewage and solid impurities. The sewage flows into the sewage collection tank from the filter holes. Because the filter plate is inclined at a certain angle, the filtered solid impurities slide into the impurity collection tank due to their own gravity.

[0017] 2. The utility model sets a cleaning mechanism. When impurities that are difficult to slide off remain on the filter plate, the staff starts the electric push rod, which extends and retracts to make the scraper contact the filter plate. The staff starts the reduction motor. The start of the reduction motor will drive the shaft to rotate forward or reverse. Because the external thread on the outer wall of the shaft is threadedly engaged with the threaded hole on the movable plate, the movable plate will make a linear motion on the outer wall of the shaft when the shaft rotates forward or reversely. The linear motion of the movable plate on the outer wall of the shaft can indirectly drive the scraper to make a linear motion along the direction of the filter plate. When the scraper makes a linear motion along the direction of the filter plate, the impurities on the filter plate can be scraped off into the impurity collection tank.

[0018] Therefore, from the above, it can be seen that the utility model mainly filters impurities in sewage, can effectively separate impurities from sewage, and the separated impurities will automatically fall into the impurity collection tank due to their own gravity. There is no need for manual frequent cleaning of impurities on the filter plate, which reduces the labor intensity of the staff, also reduces labor costs, and has strong practicality.

The bottom end of the support plate 6 is installed on the top of a sewage collecting tank body 7, the sewage collecting tank body 7 is installed on one side of the upper surface of the base 8, and an impurity collecting tank body 9 is installed on the other side of the upper surface of the base 8. The cleaning mechanism 4 includes a sealing door 401, a safety lock 402, a mounting plate 403, a scraper 404, a first rainproof shutter 405, a protective cover body 406, a second rainproof shutter 407, a strip slot 408, and a connecting plate 40 9. Shell 410, shaft 411, reduction motor 412, partition 413, slide rail 414, moving plate 415, slider 416, connecting rod 417, threaded hole 418 and electric push rod 419. A partition 413 is installed on one side of the shell 410. A reduction motor 412 is installed between an outer wall of one side of the partition 413 and an inner wall of one side of the shell 410. The reduction motor 412 is installed at the bottom end of the shell 410. The output shaft of the reduction motor 412 is connected to the shaft 411 through a coupling. The other end of the shaft 411 passes through the bearing on the outer wall of the partition 413 and is installed in the bearing on the outer wall of one side of the shell 410. A moving plate 415 is installed on the outer wall of the rotating shaft 411. A connecting rod 417 is installed on the front end wall of the moving plate 415. 17, the other end of the connecting rod 417 passes through the strip slot 408 and extends to the outside to connect with the connecting plate 409, the top of the connecting plate 409 is installed with a mounting plate 403, the upper surface of the mounting plate 403 is installed with a protective cover body 406 and an electric push rod 419, and the electric push rod 419 is located on the inner side of the protective cover body 406, the bottom end of the electric push rod 419 passes through the surface of the mounting plate 403 and is connected with the scraper 404, when the utility model filters solid impurities from sewage, the staff makes the sewage fall from the top of the filter plate 2 onto the filter plate 2, the filter hole 3 on the filter plate 2 filters the sewage and solid impurities, the sewage will flow into the sewage collection tank 7 from the filter hole 3, because the filter plate 2 is at a certain inclination angle, so that the filtered solid impurities The impurities will slide into the impurity collecting tank 9 due to their own gravity. When impurities that are difficult to slide off remain on the filter plate 2, the staff starts the electric push rod 419, which retracts and makes the scraper 404 contact the filter plate 2. The staff starts the reduction motor 412. The reduction motor 412 starts and drives the shaft 411 to rotate forward or reverse. Because the external thread on the outer wall of the shaft 411 and the threaded hole 418 on the moving plate 415 are threadedly engaged, when the shaft 411 rotates forward or reversely, the moving plate 415 will make a linear motion on the outer wall of the shaft 411. The linear motion of the moving plate 415 on the outer wall of the shaft 411 can indirectly drive the scraper 404 to make a linear motion along the direction of the filter plate 2.When the scraper 404 moves linearly along the direction of the filter plate 2, the impurities on the filter plate 2 can be scraped off into the impurity collection tank 9. Therefore, from the above, it can be seen that the utility model mainly filters the impurities in the sewage, and can effectively separate the impurities from the sewage. The separated impurities will automatically fall into the impurity collection tank 9 due to their own gravity. There is no need to manually clean the impurities on the filter plate 2 frequently, which reduces the labor intensity of the staff and also reduces the labor cost.

Due to the matching arrangement of the slider 416 and the slide rail 414, the movement of the movable plate 415 can be limited and guided, thereby avoiding the situation that the movable plate 415 rotates with the rotation of the rotating shaft 411. The slide rail 414 is installed on the rear end wall inside the shell 410, and the strip slot 408 is opened at the front of the shell 410. On the end wall, the outer wall of the connecting rod 417 and the hole wall of the strip slot 408 are connected with a gap. Since the outer wall of the connecting rod 417 and the hole wall of the strip slot 408 are connected with a gap, it can further play a role of limiting and guiding the movement of the movable plate 415.
