Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment pools, in particular to a sewage treatment pool. Background Art

[0002] In sewage treatment systems, scum generated by the sewage treatment process usually floats on the surface of the liquid in sedimentation tanks or grit chambers. Scum is a waste product continuously generated during the sewage treatment process and needs to be cleaned promptly. Existing scum cleaning operations usually use scum scrapers on scrapers or sand suction machines to push the scum floating on the liquid surface into the scum tank along with a large amount of liquid. The scum is then manually salvaged and packaged. This not only complicates the cleaning process but also increases unnecessary working time for staff.

[0003] In this regard, the sewage treatment tank provided in the authorization announcement No. CN 219469775 U scrapes away the scum on the surface of the sewage tank by moving a scraper, but the device cannot scrape away the suspended scum. Utility Model Content

[0006] Preferably, rotatable running wheels are installed at the bottom end of the dirt-blocking screen near the front and rear ends.

[0007] Preferably, a power supply is fixedly mounted on the mounting plate, and the power supply is electrically connected to the pump body and the hydraulic rod through a wire.

[0008] Preferably, the cross section of the scraper is a trapezoidal structure that is larger at the top and smaller at the bottom.

[0009] Preferably, a sewage outlet communicating with the interior of the collecting box is provided on one side of the bottom end thereof, and a valve is fixedly mounted on the sewage outlet.

[0010] Preferably, the motor is a forward and reverse rotating motor.

[0011] In summary, the technical effects and advantages of the utility model are:

[0012] In the utility model, the screw is driven by a motor to rotate and the horizontal plate is driven to move horizontally. During the movement, the dirt-blocking screen is driven to intercept the suspended and floating slag inside the sewage pool on its surface. When the dirt-blocking screen moves to the end of the sewage pool, the hydraulic rod drives the scraper to scrape the slag upward from the bottom of the dirt-blocking screen. The slag enters the groove of the scraper, and the pump body is opened to send the slag into the collection box through the suction nozzle and the suction pipe for collection, thereby realizing efficient slag cleaning operations.
