The hydraulic pressure-pressing mechanism of the press filter consists of a hydraulic station, an oil cylinder, a piston, a piston rod, and a Haffland card hydraulic station connected with a pressure plate, comprising a motor, oil pump, overflow valve (regulating pressure) reversing valve, pressure gauge, oil circuit, and fuel tank.
Filtration mode: filtrate outflow of clear flow through filtration and undercurrent filtration. Clear flow filtration, each filter plate below the liquid hole fitted with water Tsui, the filtrate is directly discharged from the nozzle, and the undercurrent is filtered, and the bottom of each filter plate is provided with a liquid channel hole, and a plurality of filter plates are connected into a liquid outlet, which is expelled by a pipe connected by the outlet hole under the thrust plate.
Washing way: When the filter cake needs washing, sometimes the flow of one-way washing and bidirectional washing, the undercurrent of unidirectional washing and bidirectional washing.
