Automatic blowdown system

Abstract

The invention relates to an automatic sewage discharge system which is used for discharging sewage in a sewage pool into a sedimentation pool, an overground obstacle higher than the sewage pool is arranged between the sewage pool and the sedimentation pool, the automatic sewage discharge system comprises an electric valve, a flow promoting pump, a filter box, a drainage suction pipe, a drainage drainage pipe, a water level sensor and a controller, and the water level sensor is electrically connected with the input end of the controller; the output end of the controller is in driving connection with the electric valve and the flow promoting pump, the filter box is arranged in the sewage pool, a water suction opening of the drainage suction pipe is formed in the filter box, a water drainage opening of the drainage suction pipe is communicated with a water suction opening pipeline of the flow promoting pump through the electric valve, and a water drainage opening of the flow promoting pump is connected with an inlet pipeline of the drainage water drainage pipe. The drainage drain pipe crosses over obstacles on the ground, and an outlet of the drainage drain pipe is arranged at a position lower than the water level of the sewage tank, so that sewage siphoned from a pipe orifice is discharged into the sedimentation tank. The energy consumption in the pollution discharge process can be reduced.

Description

technical field [0001] The invention relates to the technical field of sewage systems, in particular to an automatic sewage system. Background technique [0002] In the factory, there is a workshop barrier between the sewage tank and the sedimentation tank. When the sewage in the sewage tank reaches a certain height, how to automatically discharge the sewage in the sewage tank into the sedimentation tank is a problem that needs to be solved. [0003] Patent document CN204919793U discloses a sewage lifter, comprising: a channel steel base; a box body installed on the channel steel base through a flexible pad, which has a plurality of water inlets, and the inner wall of the box body is arranged in sequence from top to bottom. For the first liquid level sensor for prompting an alarm, the second liquid level sensor for starting the double water pump, and the third liquid level sensor for stopping the water pump, the top of the box is provided with a box controlled by an interna...
