Description
Technical Field
The utility model relates to an efficient automatic sewage water filter.
Background
Due to the increasing shortage of water resources, the sewage needs to be filtered and reused in many occasions, such as petrochemical industry, daily use, tool cleaning and the like.
Most of the existing water treatment schemes adopt a filter screen mode for treatment, and after the filter screen is used for a period of time, a large amount of attachments are attached to the surface of the filter screen, so that the recycling capability of the filter screen is influenced, and particularly in eutrophicated water, a large amount of growth of microorganisms is also caused, so that the limited fresh water resources are further deteriorated.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the defects of the prior art and provides an efficient automatic sewage water filter.
An efficient automatic sewage water filter comprises an inner barrel body and an outer barrel body which are double-layer, wherein the inner barrel body and the outer barrel body are connected through an annular filter screen;
the inner part of the inner barrel body is provided with a rotating mechanism, the bottom of the rotating mechanism is connected with the mounting plate through a bearing, the top of the rotating mechanism is connected with a speed reducer, the outer part of the rotating mechanism is connected with at least two steel brushes, the inner walls of the steel brushes are connected with the rotating mechanism through connecting columns, and the outer walls of the steel brushes are abutted against the inner wall of the filter screen; the connecting column is a telescopic connecting column, and an elastic component is arranged in the middle of the connecting column.
Preferably, the diameter of the water outlet is equal to that of the water inlet.
Preferably, the water inlet and the water outlet are both provided with a connecting flange.
Preferably, the filter screen is made of stainless steel.
Preferably, a pressure difference switch is connected between the water inlet and the outer barrel body.
Preferably, the diameter of the filtering holes on the filter screen is 10 μm or more.
Preferably, the shape of the filtering holes is diamond, circle or triangle.
Preferably, the bottom and the top of the filter screen are embedded in a polyurethane cushion layer, and the thickness of the polyurethane cushion layer is 5-10 mm.
Has the advantages that:
the annular filter screen is adopted in the device, the filtering area of the annular filter screen is far larger than that of a common filtering device, and the pressure loss of the annular filter screen is far smaller than that of the common filtering device in practical application.
When microorganisms are attached to and grow on the filter screen, the microorganisms on the inner surface of the filter screen can be effectively cleaned through the steel brush by starting the rotating mechanism, so that the cleaning and filtering effects of the filter screen are ensured. Meanwhile, in order to prevent the filter screen from deforming to cause the reduction of the cleaning effect, a telescopic connecting column (elastic part) is adopted in the device to be connected with the steel brush so as to ensure that the steel brush is always abutted against the inner wall of the filter screen.
