For high pressure oil filter press hydraulic compression mechanical compaction, hydraulic station, components of cylinders and the piston cavity is filled with fluid when the pressure is greater than the frictional resistance of the compression plate run, pressed board pressed slowly filter plate, when the pressing force of the relief valve set pressure value (shown by the gauge pointer), the filter plate, filter box (frame type) or filter plate (van) has been pressed, the relief valve starts unloading, then cut off electrical power, the compression action is completed, returned, reversing valve, the pressure oil into the cylinder rod chamber, when the oil pressure can overcome the compression plate the frictional resistance, the pressing plate returned.

        Hydraulic compression of the filter press for automatic packing, pressing force is controlled by the electric contact pressure gauge, set the pointer to the upper limit and lower limit pointer of the pressure gauge the value of process requirements, when the pressing force of the pressure gauge the upper limit of power is cut off, pump to stop power supply limit is reached, the pressure may be generated by the hydraulic system leakage and leakage caused by the pressing force is decreased, down to the pressure gauge the lower limit pointer, power supply connected, the pump began to oil supply, when the power is cut off, the oil pump to stop fuel supply so that the cycle in order to reach the filter materials to ensure that the effect of compaction force.

        Filtration: filtrate outflow distinct flow filtration and undercurrent filter. Out-flow filtration, each filter plate below the liquid hole is equipped with water nozzles, the filtrate intuitive outflow from the water nozzles. Undercurrent filtering, the bottom of each filter plate has a fluid channel pore, the number of blocks of the filter plate liquid Kong Liancheng a fluid channel, by the thrust plate below the liquid hole is connected to the pipeline discharge.

        Washing method: cake need washing, sometimes flow-way washing and two-way washing undercurrent check washing and two-way washing. Free flow check washing, turn into the lotion from the lotion into the hole of the thrust plate, through the cloth and then through the filter cake, never Kong filter plate outflow, when the orifice of a liquid water nozzle is turned off. orifice liquid water nozzles are turned on. Free flow two-way wash, lotion thrust panel on both sides of the side of the lotion into the hole twice washing lotion to start with the side of the wash and then another example of washing, lotion export and import is diagonal direction, so called bi-directional cross-washing. Undercurrent one-way flow of polyester lotion of the lotion from the thrust plate into the hole in order to enter the orifice, through the cloth and then through the filter cake, never Kong filter plate outflow. Undercurrent of two-way washing lotion lotion into the hole from both sides of the two only board side has two washing, washing start side of the washing, and then another example of washing the export of the lotion is a diagonal direction, it is also called the undercurrent of a two-way cross-washing.

      The Zhucheng innovative Chinese Environmental Protection Technology Co., Ltd. produces a variety of filter press products are widely used in various industries.
