Buffer type solid-liquid separator

Abstract

The invention provides a buffer type solid-liquid separator. The buffer type solid-liquid separator comprises an inlet pipe (10) and an output pipe (20), wherein a middle connecting pipe (30) is connected to the rear end of the inlet pipe (10), the output pipe (20) is connected to the rear end of the middle connecting pipe (30), a filter net (1) is arranged in the middle connecting pipe (30), a solid separation pipe portion (2) extending downwards is arranged on the lower portion of the middle connecting pipe (30), and a check valve (3) is fixed to the top of the solid separation pipe portion (2). The buffer type solid-liquid separator is simple and compact in structure, reasonable in design, reliable in operation and capable of preventing impurities from blocking the filter net and making impurities gathered automatically; meanwhile, the middle connecting pipe is detachable, so that cleaning is convenient.

Description

Technical field: [0001] The technology of the present invention relates to the technical field of drainage pipeline system, and more specifically relates to a buffer type solid-liquid separator. Background technique: [0002] At present, most buildings use water-saving sanitary appliances, which increases the concentration of domestic sewage in the basement. During the lifting and discharge process, it is easy to cause the sewage pump to be blocked, so a filter-type integrated sewage lifting equipment is used. This type of equipment adopts a backwash filter device to separate sewage and dirt, prevent direct contact between dirt and water pumps and cause pump blockage, and greatly improve the capacity of sewage discharge. However, during operation, the water pressure will release pressure and flow in the backwash filter device, and the filter mesh in the filter will easily retain soft dirt, which will accumulate and cause blockage. In addition, when the building drains downw...

Problems solved by technology

However, during operation, the water pressure will release pressure and flow in the backwash filter device, and the filter mesh in the filter will easily retain soft dirt, which will accumulate and cause blockage

In addition, when the building drains downward, it enters the water storage tank from the outlet of the pump after being filtered, which may easily cause the pump to reverse, the motor to generate electricity, the impeller to loosen, and the equipment to fail to work normally.
