Description

A filter that automatically removes impurities

technical field

The utility model relates to the technical field of filters, in particular to a filter for automatically cleaning impurities.

Background technique

Automatic internal brush filter is a kind of filter. Automatic internal brush filter is a kind of filter that directly intercepts impurities in water, removes suspended solids and particulate matter in water, reduces turbidity, purifies water quality, and reduces system dirt and bacteria. Algae, rust, etc., to purify the water quality and protect the precision equipment of other equipment in the system. The water enters the fully automatic filter body from the water inlet pipe. The system can automatically identify the degree of impurity deposition and give the signal to the sewage valve to automatically discharge the sewage; when the water passes through the filter When the filter is used, the mechanical impurities in the water are intercepted by the filter screen. When the accumulated impurities on the surface of the filter screen increase and the pressure difference reaches the set pressure difference, the differential pressure switch will send out a signal, and the control box will send out an instruction at the same time. The transmission motor will start and the sewage will be discharged. When the valve is opened, the impurity deposited in the filter screen is brushed down by the rotating brush and discharged from the sewage outlet. The whole scrubbing and sewage discharge process does not require personnel operation or shutdown. The water outlet is safe and reliable under any circumstances.

The existing automatic internal brush filter is usually provided with a filter screen in the filter housing, and a stainless steel brush is arranged inside the filter screen. The stainless steel brush is driven by an electric motor, and the water inlet pipe and the water outlet pipe are respectively located on both sides of the filter screen. The water flowing in from the water inlet pipe will flow out from the outlet pipe through the filter to achieve the water purification effect. At the same time, the electric motor can drive the stainless steel brush to rotate, so that the impurities on the filter are brushed off and discharged from the sewage outlet to realize automatic cleaning. Cleaning function, but in order not to affect the cleaning of the filter screen, most of the existing automatic internal brush filters only have one layer of filter screen, which makes the filtering effect of the device not good, and the impurities intercepted above the filter screen are easily stuck by the stainless steel brush , it is difficult to fall to the bottom of the filter housing, making it difficult for impurities to be completely discharged from the sewage outlet. Therefore, we propose a filter that automatically cleans impurities.
