Abstract

The utility model provides a filter with a fully automatic washing and blowdown device, which need not people watch. The positions of connection tubes of a liquid inlet and a liquid outlet of the filter are respectively provided with a liquid pressure detecting head, and a control circuit system of the filter is provided with a pressure difference signal transmitter. When a filter screen of the is clogged, the liquid inlet and the liquid outlet occur pressure difference, and signals are transmitted to a control circuit through the pressure detecting head so as to further cause an intermittent drive mechanism for controlling the washing and blowdown device to work. As a result, the washing and blowdown device of the filter can be driven to back flush and wash a filter element, and drain impurities in the liquid to a drainage tube. Until the pressure difference at the positions of the liquid inlet and the liquid outlet of the filter achieve an ideal value, the filter can continuously and normally work through the circuit control system and the intermittent mechanism.
