Abstract
The utility model discloses a high-pressure manual pilot backwash filtration station comprising a filter main body, a filter and a manual pilot valve. A main valve core arranged in the filter main body is provided with a control opening. A liquid inlet sequentially passes through the filter main body and the filter and is connected with a work opening. The work opening sequentially passes through the filter and the filter main body and is connected with a sewage outlet. The work opening is connected with the control opening through the manual pilot valve. Under normal working state, the manual pilot valve cuts off a passage between the work opening and the control opening. The liquid inlet sequentially passes through the filter main body and the filter and is communicated with the work opening, and the sewage outlet is closed. Under the backwash state, the manual pilot valve breaks over the passage between the work opening and the control opening, and the liquid inlet is closed. The work opening sequentially passes through the filter and the filter main body and is communicated with the sewage outlet. Service life of combined mining equipment is prolonged and production efficiency is improved due to the fact that filtration of work impurities in a hydraulic system is carried out, and backwash of the filter is carried out on the condition that normal work of a work face is not influenced.
