Product Description
The structure of the environmentally friendly Filter Press consists of three parts:

Folding rack
The frame is the basic component of the filter press, with thrust plates and compression heads at both ends. The two are connected by girders on both sides. The girders are used to support the filter plate, filter frame and compression plate. To meet advanced hygiene requirements, the rack needs to be clad in stainless steel. The stainless steel cladding technology can be used as a reference, and its quality can meet the needs of European customers.

A. Thrust plate: It is connected with the support and places one end of the filter press on the foundation. The middle of the thrust plate of the chamber filter press is the feed

There are four holes in the four corners. The holes in the upper two corners are the inlet of the washing liquid or pressed gas, and the two lower corners are the outlet (underflow structure or filtrate outlet).

b. Compression plate: used to compress the filter plate and filter frame. The rollers on both sides are used to support the compression plate rolling on the track of the girder.

C. Beam: It is a load-bearing component. According to the anti-corrosion requirements of the use environment, it can be coated with rigid polyvinyl chloride, polypropylene, stainless steel coating or new anti-corrosion coating.

Folding and pressing mechanism
Manual pressing, mechanical pressing, hydraulic pressing.

A. Manual compression: a screw mechanical jack is used to push the compression plate to compress the filter plate.

B. Mechanical compression: The compression mechanism consists of a motor (equipped with an advanced overload protector), a reducer, a gear pair, a screw and a fixed

Composed of nuts. When compressing, the motor rotates forward, driving the reducer and gear set, causing the screw rod to rotate in the fixed nut, pushing the compression plate to compress the filter plate and filter frame. When the pressing force becomes larger and larger, the load current of the motor increases. When it reaches the current value set by the protector, the maximum pressing force is reached, the motor cuts off the power supply and stops rotating. Since the screw rod and the fixed nut have reliable The self-locking helix angle can reliably ensure the pressing state during the working process. When retracting, the motor reverses. When the pressing block on the pressing plate touches the travel switch, the retracting stops.

C. Hydraulic compression: The hydraulic compression mechanism consists of a hydraulic station, a cylinder, a piston, a piston rod, and a connection between the piston rod and the compression plate.

The structure of the connected Hafland card hydraulic station consists of: motor, oil pump, relief valve (pressure adjustment) reversing valve, pressure gauge, oil circuit, and oil tank. When the hydraulic compression machine is compressing, the hydraulic station supplies high-pressure oil, and the component cavity composed of the oil cylinder and the piston is filled with oil. When the pressure is greater than the friction resistance of the compression plate operation, the compression plate slowly compresses the filter plate. When the tightening force reaches the pressure value set by the relief valve (displayed by the pressure gauge pointer), the filter plate, filter frame (plate and frame type) or filter plate (box type) are pressed tightly, and the relief valve begins to unload. , cut off the motor power, the pressing action is completed, when retracting, the reversing valve reverses direction, and the pressure oil enters the rod cavity of the oil cylinder. When the oil pressure can overcome the frictional resistance of the pressing plate, the pressing plate begins to retreat. When the hydraulic pressing is automatic pressure maintaining, the pressing force is controlled by the electric contact pressure gauge. Set the upper limit pointer and the lower limit pointer of the pressure gauge to the values required by the process. When the pressing force reaches the upper limit of the pressure gauge, the power supply cut off, the oil pump stops supplying power. Due to the internal and external leakage that may occur in the oil system, the pressing force decreases. When it drops to the lower limit pointer of the pressure gauge, the power is turned on and the oil pump starts supplying oil. When the pressure reaches the upper limit, the power supply is cut off. The oil pump stops supplying oil and circulates in this way to ensure the effect of compressing force during the process of filtering materials.

pleated filter mechanism
The filter mechanism consists of a filter plate, a filter frame, a filter cloth, and a press diaphragm. Both sides of the filter plate are covered by filter cloth. When a press diaphragm is required, a set of filter plates consists of a diaphragm plate and side plates. The base plate of the diaphragm plate is covered with rubber diaphragms on both sides, and the outside of the diaphragm is covered with filter cloth. The side plates are ordinary filter plates. The material enters each filter chamber from the material hole on the thrust plate. The solid particles are trapped in the filter chamber because their particle size is larger than the pore size of the filter medium (filter cloth). The filtrate flows out from the outlet hole below the filter plate. When the filter cake needs to be squeezed dry, in addition to squeezing with a diaphragm, compressed air or steam can also be passed through the washing port, and the air flow can wash away the water in the filter cake to reduce the moisture content of the filter cake.

(1)Filtering method

The way the filtrate flows out is divided into clear flow filtration and undercurrent filtration.

A. Open flow filtration: The outlet hole at the bottom of each filter plate is equipped with a water nozzle, and the filtrate flows out of the water nozzle intuitively.

B. Undercurrent filtration: There is a liquid outlet hole under each filter plate, and the liquid outlet holes of several filter plates are connected to form a liquid outlet channel.

channel, discharged from the pipe connected to the liquid outlet hole under the thrust plate.

(2)Washing method

When the filter cake needs to be washed, there are open flow one-way washing and two-way washing, and undercurrent one-way washing and two-way washing.

A. Open flow one-way washing means that the lotion enters sequentially from the lotion inlet hole of the thrust plate, passes through the filter cloth and then through the filter cake, and flows out from the non-porous filter plate. At this time, the liquid outlet nozzle of the perforated plate is closed. status, the liquid outlet nozzle of the non-orifice plate is open.

B. Open flow two-way washing means that the washing liquid is washed twice from the washing liquid inlet holes on both sides above the thrust plate, that is, the washing liquid is washed from one side first and then from the other side. The outlet of the washing liquid is opposite to the inlet. Angular direction, so it is also called two-way cross washing.

C. Undercurrent unidirectional flow washing means that the washing liquid enters the perforated plate from the washing liquid inlet hole of the thrust plate, passes through the filter cloth and then through the filter cake, and flows out from the non-porous filter plate.

D. Undercurrent two-way washing is that the washing liquid is washed twice successively from the two washing liquid inlet holes on both sides above the stop plate, that is, the washing is washed from one side first, and then from the other side. The outlet of the washing liquid is diagonal. direction, so it is also called undercurrent two-way cross-washing.

(3) Filter cloth: Filter cloth is a main filter medium. The selection and use of filter cloth play a decisive role in the filtration effect. When selecting, appropriate filter cloth should be selected based on the PH value of the filter material, solid particle size and other factors. The material and pore size are selected to ensure low filtration cost and high filtration efficiency. When using, make sure the filter cloth is flat and undistorted and the pore size is unobstructed.

Generally speaking, the greater the filtration rate, the lower the moisture content of the swimming cake obtained in the same overflow time. On the other hand, the greater the filtration rate, the greater the amount of sludge processed per unit time.
