Description

Technical Field

[0001] The present application relates to the technical field of sewage treatment, and in particular to a self-cleaning sewage treatment reaction tank. Background Art

[0002] In the process of sewage treatment, special reaction tanks are used. Through the reaction process inside the tanks (such as physical mixing, chemical reaction, biodegradation, etc.), harmful substances in the sewage, such as suspended solids, organic matter, heavy metal ions, etc., are removed so that the treated water quality meets the discharge standard or reuse requirements. By adding coagulants to the sewage, the suspended solids and colloidal particles in the sewage are aggregated and form larger flocs, which are then separated from the sewage by sedimentation or filtration. The anaerobic reactor uses the metabolism of anaerobic microorganisms to decompose organic matter in the sewage into gases such as methane and stable inorganic substances, thereby purifying the sewage. However, in the process of sewage treatment, dirt will adhere to the inside of the tank. Due to the small opening, manual cleaning is more troublesome, and during the cleaning process, the cleaning mechanism becomes dirty, resulting in residual dirt, which affects the cleaning efficiency.

At the same time, the cleaning brush strip can be replaced through motor No. 2, rotating roller, fixed slot and fixed bolt. The cleaning brush strip will become dirty after cleaning for a period of time. At this time, motor No. 2 is started to drive the rotating roller to rotate, so that the fixed slot rotates with the cleaning brush strip, so that the next cleaning brush strip can contact the inner wall of the tank body, and the dirty cleaning brush strip can be loosened by loosening the fixing bolt when it rotates to the other side of the rotating roller and then pulled out of the fixed slot for cleaning and replacement, thereby ensuring the cleaning efficiency of the device.

[0006] As an optional solution of the technical solution of the present application, a fixing bolt is threadedly connected to the upper side of the outer wall of the fixing groove, and the fixing bolt passes through the outer wall of the fixing groove and contacts the cleaning brush strip.

[0007] As an optional solution of the technical solution of the present application, a filter screen is detachably connected to the inner wall of the tank body below the vertical rod.

[0008] As an optional solution of the technical solution of the present application, the inner width of the plug-in slot is consistent with the width of the plug-in rod.

[0009] As an optional solution of the technical solution of the present application, the surface of the scraper facing the inner wall of the tank body is in contact with the inner wall of the tank body, and the cleaning brush strip on one side of the inner wall of the tank body is in contact with the inner wall of the tank body.
