Aeration tank with desilting function

Abstract

The invention discloses an aeration tank with a desilting function. The aeration tank comprises a tank body, a fixed frame, an aeration motor, an aeration plate and an air blower, wherein the fixed frame is fixedly connected to the top of the tank body, the aeration motor is fixedly connected to the lower surface of the fixed frame, the shaft extending end of the aeration motor is fixedly connected with a driving shaft, driven shafts are respectively arranged on the left side and the right side of the driving shaft, a screw rod is arranged at the bottom of the tank body, the left end and the right end of the screw rod are respectively in rotary connection with a lateral wall of the tank body, and a desilting motor is fixedly connected to an outer wall of the left side of the tank body; theair blower is utilized for conveying air into the aeration plate to be exhausted into sewage to aerate bottom-layer sewage; a movable plate moves left and right to drive the aeration plate to move left and right at the same time, the movable plate is utilized for scraping sludge at the bottom into a desilting tank, and a sewage pump is utilized for exhausting the sludge in the desilting tank out;thus, the sludge is prevented from being deposited at the bottom of the tank body, the trouble in manually cleaning the sludge is avoided, the aeration plate moves left and right to expand an aeration range, and an aeration efficiency is further improved.

Description

technical field [0001] The invention relates to the field of environmental protection equipment, in particular to an aeration tank with a dredging function. Background technique [0002] The random discharge of sewage will have a great negative impact on the environment. At present, people often use aeration tanks to treat sewage. The aeration tank is a structure that uses activated sludge method for sewage treatment. The system and the water inlet and outlet are composed of three parts. The pool body is generally built with reinforced concrete, and its planar shape is rectangular, square and circular; aeration is a means to make air and water come into strong contact, and its purpose is to dissolve oxygen in the air in water. The aeration structure of the aeration device is single, and the mixing of sewage and air is not sufficient, resulting in low aeration efficiency, and the bottom of the aeration tank is prone to deposits of sludge, requiring regular manual cleaning of...

The pool body is generally built with reinforced concrete, and its planar shape is rectangular, square and circular. Aeration is a means of making air and water come into strong contact. Its purpose is to dissolve oxygen in the air into water. The existing aeration The aeration structure of the aeration device is single, and the mixing of sewage and air is not sufficient, resulting in low aeration efficiency, and the bottom of the aeration tank is prone to deposits of silt, which requires regular manual cleaning of the aeration tank, which greatly increases the workload of the workers and is very inconvenient
