The structure of the filter press consists of three parts

      1, the frame: the frame is the base parts of the filter press, both ends are thrust plate and pressing head, the two sides of the girder will be connected and persistent, the girder is used to support the filter plate, filter frame and pressing plate.

The frame needs to be covered with stainless steel for high hygiene requirements.

Hangzhou geentor stainless steel technology can be used as a reference, its quality can meet the needs of European customers.

A, thrust plate: it will connect to support pressure filter is located on the ground, at the end of the box pressure filter of the thrust plate feeding hole is among, four corners and four holes, two horns hole is washing liquid or squeeze on gas imports, with two horns for export (undercurrent structure or the filtrate outlet) b, pressure plate, used to pressure filter plate filter frame, on both sides of the roller is used to support keep plate rolling on the orbit of girder.

C, girder: is a load-bearing component, according to the requirements of the use of environmental corrosion, can choose hard PVC, polypropylene, stainless steel coating or new anticorrosive coating.

2, pressing mechanism: manual pressing, mechanical pressing, hydraulic pressing.

1. Manual pressing: screw mechanical jack is used to push the pressing plate to press the filter plate.
2. Mechanical pressing: the pressing mechanism is composed of motor (equipped with advanced overload protector) reducer, gear, screw and fixing nut.

When pressing, the motor is rotating, driving the reducer, gear pay, so that the screw rotates in the fixed wire, pushing the pressing plate to press the filter plate and the filter frame.

When the pressure force is more and more big, the motor load current increases, when the big to protector set current value, achieve bigger clamping force, motor power cut, stop running, because of the wire rod and the fixed wire mother have reliable self-locking spiral Angle, can reliably guarantee the state of compression in the process of work, to return, motor reversal, when the weight for the hold-down plate, contact to switch back to stop.

C, hydraulic pressure: hydraulic pressure mechanism is composed of hydraulic station, cylinder, piston, piston rod and piston rod and pressure plate connected with the Havlan card hydraulic station structure consists of: motor, oil pump, relief valve (regulating pressure) reversing valve, pressure gauge, oil circuit, fuel tank.

Hydraulic pressure mechanical compaction, the hydraulic station for the high pressure oil, oil cylinder and a piston component cavity filled with oil, when the pressure is greater than the pressure plate running friction resistance, pressure plate slow pressure filter plate, when the pressure force to achieve the relief valve set pressure value (by pressure gauge pointer display), filter plate, filter box (plate and frame type) or filter plate (van) is compact and started unloading overflow valve, at this time, to cut off the motor power, compaction action is complete, return, reversing reversing valve, pressure oil into the cylinder rod cavity, when the hydraulic pressure plate can be overcome frictional resistance, pressure plate began to return.

Automatic pressure for hydraulic pressure, clamp force is controlled by the electric contact pressure gauge, the gauge of the pointer and UCLA’s pointer to set the value of process requirement, when the pressure force reaches a pressure gauge highs, power cut, the oil pump to stop the power supply, oil system due to the possible leakage and leakage cause the loss of compression force, when the lower limit to the pressure gauge pointer, electricity, oil pump start fuel supply, the pressure to reach highs, power cut, oil pump fuel cut-off, such circulation filter materials in the process of guarantee in order to achieve the effect of clamping force.

The filter mechanism is composed of a filter plate, a filter frame, a filter cloth and a pressing diaphragm. Both sides of the filter plate are covered by a filter cloth. When the pressing diaphragm is needed, a group of filter plates are composed of a diaphragm plate and a side plate.

The two sides of the substrate of the diaphragm plate are covered with a rubber diaphragm, and the outside of the diaphragm is covered with a filter cloth. The side plate is a common filter plate.

The material enters the filter chamber from the hole on the thrust plate. The solid particles are trapped in the filter chamber because their particle size is larger than the aperture of the filter medium (press cloth), and the filtrate flows out from the outlet hole under the filter plate.

When the filter cake needs to be pressed dry, compressed air or steam can be used to pass through the washing port, and the water in the filter cake can be flushed by air to reduce the moisture content of the filter cake, in addition to the diaphragm pressing.
