[0009] In a further technical solution, a scraper is provided on the outer side of the filter screen.
[0010] The beneficial effects of the utility model are:
[0011] 1. The pipe connecting the first tank body and the second tank body is arranged obliquely upward, which facilitates the passage of sewage after the first step of sedimentation, while making it difficult for the precipitated sludge to pass through the pipe. Part of the sludge accumulated in the pipe can be blocked by the cleaning and filtering structure and pushed back from the pipe to the first tank body for further sedimentation, which facilitates the cleaning of the pipe, is conducive to the passage of sewage after the first sedimentation treatment, and improves the efficiency of the secondary sedimentation;
[0012] 2. The electric push rod is set on the top of the second tank body, and is extended downward to connect the movable rod through a connecting rod to avoid being affected by the sewage in the second tank body;
[0013] 3. Set a slider and a slide rail to connect the movable rod and the electric push rod to limit the movement of the movable rod and improve the driving stability;
[0014] 4. The scraper on the outside of the filter can cooperate with the movement of the filter to scrape off the sludge on the pipe wall, which is further conducive to the passage of sewage. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The embodiments of the present utility model will be further described below in conjunction with the accompanying drawings.
[0020] Example:
[0021] like Figure 1-Figure 2 As shown, a secondary fast seepage water sedimentation tank comprises a first tank body and a second tank body, a pipe connecting the first tank body and the second tank body is provided between the two, a mud discharge port is provided at the bottom of the first tank body, one end of the pipe connected to the second tank body is higher than one end of the pipe connected to the first tank body, a cleaning filter structure is provided in the pipe, comprising a filter screen and a movable rod arranged in the middle of the filter screen, the end of the movable rod extends to the outside of one end of the pipe connected to the second tank body, a driving structure connected to the end of the movable rod is provided on the second tank body, and an electric push rod can be used for the driving structure. In order to avoid being affected by the sewage in the second tank body, the electric push rod is arranged at the top of one side of the second tank body where the movable rod is located, and a connecting rod is vertically provided between the electric push rod and the movable rod.
[0022] The working principle of the above technical solution is as follows:
[0023] The first tank body and the second tank body are connected by an upward slanting pipe. The sewage in the fast seepage tank enters the first tank body, and most of the sand and sludge are settled to the bottom of the tank. The floating objects are isolated, and some sludge impurities will enter the pipe with the sewage after the first step of sedimentation. Since the pipe is set upward slantingly, the sludge impurities are not easy to pass through, and with the blocking of the filter, most of the sludge impurities entering the pipe can be blocked at the lower end of the pipe. When the pipe needs to be cleaned, the electric push rod is started, and the movable rod is driven to move through the connecting rod, so that the sludge impurities accumulated in the pipe can be pushed back to the first tank body for further sedimentation.
[0024] In another embodiment, if Figure 1 As shown, a slider is provided at the end of the movable rod, and the connecting rod is connected to the movable rod through the slider. The movable rod is parallel to the adjacent two sides of the second pool body where it is located. A slide rail matching the slider is provided on one of the inner walls of the second pool body parallel to the movable rod, and the slide rail is parallel to the movable rod.
[0025] A slide block and a slide rail are arranged to connect the movable rod and the electric push rod, so as to limit the movement of the movable rod and improve the driving stability.
[0026] In another embodiment, if Figure 2 As shown, a rubber scraper is provided on the outside of the filter. The scraper on the outside of the filter can scrape off the sludge on the pipe wall in coordination with the movement of the filter, further facilitating the passage of sewage.
[0027] The above-mentioned embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
