Problems solved by technology

There are three major disadvantages: first: complex structure, high cost, and large power consumption (using water pump to flush); second: the dirt after flushing remains in the pipeline, and the second time may absorb and block the filter; third: due to There is a backflow phenomenon in the water in the pipeline, which will lose part of the energy

Abstract

The invention discloses a sewage filter plant, which comprises a support, a water inlet channel, a rotating disc, a rotating shaft, a water scouring sprayer, a driving motor and a speed reducer. Two filters capable of switching are arranged on a suction opening pipeline of a water pump, a pressure sensor automatically detects a water pressure setting value, when blocked, a filter screen is automatically replaced and cleaned, the total process is finished instantly, and the water pump does not stop. The sewage filter plant has the advantages of simple structure, low cost and power consumption, capabilities of effectively avoiding blockage due to dirt and guaranteeing stable operation of a system, and the like.

Description

technical field [0001] The invention belongs to the field of sewage treatment equipment and relates to a sewage solid matter filtering device. Background technique [0002] Urban sewage is an excellent and eye-catching "cold / heat source". The heat (cold) energy stored in urban sewage discharge can be utilized through heat pump technology to meet the needs of building air conditioning and domestic hot water to achieve energy conservation and emission reduction. For purposes, the system is called a sewage source heat pump system. [0003] During the use of the sewage source heat pump system, the sewage must be strictly filtered to reach the state required by the heat pump heat exchange device. The composition of urban sewage is complex, and the size span of the dirt is large. It is easy to accumulate scale in the heat exchanger and block the filter screen. The dirt is usually corrosive and will damage the equipment if it is not removed in time. Once the heat exchange equipme...
