Description

An inclined tube sedimentation tank cleaning device

technical field

The utility model relates to the technical field of sewage treatment equipment, in particular to a cleaning device for an inclined tube sedimentation tank.

Background technique

The inclined tube sedimentation tank is a type of sedimentation tank that is widely used in the conventional water treatment process in my country. The tubular components form a certain angle (generally about 60 degrees) with the horizontal plane and are placed in the sedimentation tank. The water flow can flow from top to bottom. The particles settle to the bottom of the inclined tube assembly and then slide down automatically. The inclined tube sedimentation tank has a high sedimentation efficiency. However, some flocs and sludge will adhere to the surface and top of the inclined tube assembly of the sedimentation tank during long-term use, resulting in poor sedimentation effect of the inclined tube assembly and affecting the water quality of the effluent. , so the regular cleaning of the inclined tube assembly in the inclined tube sedimentation tank is an extremely important task in the operation of the inclined tube sedimentation tank.

At present, the inclined pipe of the sedimentation tank is usually cleaned by a hydraulic cleaning machine, the water level in the sedimentation tank is lowered, and then the inclined pipe assembly is flushed with a high-pressure water gun. However, this method has the following defects: (1) a large amount of water is required, resulting in a waste of water resources; (2) since the flushing is performed manually by the operator, the labor cost is high; (3) when flushing, the inclined tube sedimentation tank cannot operate , the shutdown time is longer; (4) The flushing effect is limited. Due to the influence of the inclination and depth of the inclined pipe assembly, the cleaning effect of the water gun is only at the upper part of the inclined pipe assembly about 20-30cm, and the lower flushing effect is almost zero; (5) There is a big risk, and the operator needs to stand on the inclined pipe assembly for flushing. Due to the load bearing and instability of the inclined pipe assembly, although the operator wears a safety belt for operation, there is still a relatively high risk.
