Full automatic suction type self-cleaning filter

Abstract

The invention discloses a full-automatic suction self-cleaning filter comprising a casing, a filter screen, a mandrel, a soil pick-up pipe, a sucker, a driving device and a control system. Wherein, the casing is divided into a cleaning room and a soil exhaust room while the filter screen is mounted in the cleaning room, the mandrel is mounted in the casing to through the filter screen; the soil pick-up pipe is fixed on the mandrel; the sucker is mounted on the outer surface of soil pick-up pipe of cleaning room to be connected with the soil pick-up pipe; the casing has a water inlet and a water outlet; the filter screen has a water inlet connected to the one of casing; the floss hole of soil pick-up pipe is arranged in the soil exhaust room which has a soil exhaust hole through with outside; a soil exhaust valve is mounted on the floss hole or the soil exhaust hole; the driving device can rotate the mandrel when moves along the axis of mandrel; and the control system and the driving device are connected to the soil exhaust valve. The invention operates automatically without interrupted water supply to realize the intelligent control. And the invention has short reverse washing time, and lower water consumption for exhausting soil to save water and power resource.

Description

technical field [0001] The invention relates to equipment in the field of environmental protection, in particular to a fully automatic suction type self-cleaning filter for water recycling. Background technique [0002] my country's water resources are very scarce, rational and effective use of water resources can not only reduce the production cost of enterprises, but also benefit the country and the people. At present, large industrial water users such as steel mills, papermaking, power generation and other industries implement water recycling for industrial water use to make full use of water resources. In the process of water treatment, filtration is a very important link. The filter is used to intercept large suspended solids in the water to ensure the normal operation of other equipment in the system. However, the traditional filter has defects such as small dirt holding capacity, easy to be blocked by dirt, the filter part needs to be disassembled and cleaned, and th...

Problems solved by technology

However, the traditional filter has defects such as small dirt holding capacity, easy to be blocked by dirt, the filter part needs to be disassembled and cleaned, and the filtration status cannot be monitored. The maintenance of the equipment is not only cumbersome and needs to be shut down for cleaning, but also the automation of the whole system is low.
