The design of the channel press comprises of three sections.
The edge is the essential piece of the channel press. The two finishes are the halting plate and the squeezing head, and the bars on the two sides are utilized to help the channel plate, the channel outline and the squeezing plate.
1, push plate: it is associated with the help to arrange one finish of the channel push on the establishment, the center of the push plate of the chamber channel press is the delta opening, and there are four openings at the four corners, the openings at the upper two corners are the washing fluid or squeezing gas bay, and the lower two corners are the power source (dull stream construction or filtrate outlet).
2、Pressing plate: used to press the channel plate and channel outline, the rollers on the two sides are utilized to help the moving of the squeezing plate on the track of the bar.
3、Big pillar: It is a heap bearing part, which can be covered with hard PVC, polypropylene, tempered steel cladding or new enemy of consumption coatings as per the prerequisites of the utilization climate for erosion assurance. 
Manual squeezing, mechanical squeezing, pressure driven squeezing.
1、Manual squeezing: the screw type mechanical jack is utilized to push the squeezing plate to press the channel plate.
2、Mechanical squeezing: the squeezing component comprises of engine (furnished with cutting edge over-burden defender) reducer, gear installment, screw and fixed nut. When squeezing, the engine is turning, driving the reducer and stuff installment, causing the fiber bar to pivot in the proper nut, pushing the squeezing plate to press the channel plate and channel outline. At the point when the squeezing power expands and greater, the engine load current increments, when it arrives at the current worth set by the defender, the most extreme squeezing power is reached, the engine cuts off the power supply and quits turning, on the grounds that the fiber pole and the decent fiber mother have a dependable self-locking twisting point, it can dependably guarantee the squeezing state during the functioning system, when it is returned, the engine inverts, when the tension square on the squeezing plate contacts the movement switch, it is gotten back to stop.
3, water powered squeezing: water powered squeezing instrument comprises of a water powered station, oil chamber, cylinder, cylinder pole and cylinder bar and squeezing plate associated with the Havlan card pressure driven station structure comprises of: engine, oil siphon, help valve (to change the tension) turning around valve, pressure measure, oil circuit, oil tank. At the point when the water driven squeezing hardware is squeezed, the high tension oil is provided by the pressure driven station, the part cavity shaped by the oil chamber and cylinder is loaded up with oil, when the strain is more prominent than the frictional opposition of the squeezing plate running, the squeezing plate gradually presses the channel plate, when the squeezing power arrives at the tension worth set by the help valve (shown by the pointer of the tension measure), the channel plate, channel outline (plate and edge type) or channel plate (chamber type) is squeezed, the alleviation valve begins to dump, right now, the power supply to the engine is cut off and When the squeezing activity is finished, the turning around valve is switched and the strain oil enters the pole pit of the chamber, when the oil tension can defeat the rubbing obstruction of the squeezing plate, the squeezing plate begins to return. At the point when the tension arrives at the maximum furthest reaches of the strain measure, the power supply will be cut off and the oil siphon will quit providing power, as the inward and outside spillage of the oil circuit framework might make the strain drop, when it arrives at the lower furthest reaches of the strain check, the power supply will be turned on and the oil siphon will begin providing oil, the tension will arrive at When the tension arrives at as far as possible, the power supply is cut off and the oil siphon quits providing oil, with the goal that the cycle can accomplish the impact of guaranteeing the squeezing power during the time spent separating materials. 
The sifting component comprises of a channel plate, a channel outline, a channel material and a squeezing stomach. The stomach plate is covered with elastic stomach on the two sides of the substrate, the stomach is covered with channel material outwardly, and the side plate is the normal channel plate. The strong particles are held in the chamber on the grounds that their molecule size is bigger than the pore size of the channel media (channel material), while the filtrate streams out from the power source opening underneath the channel plate. At the point when the channel cake should be squeezed dry, notwithstanding the stomach press, packed air or steam can be utilized to go through the washing port, and the wind current washes away the water in the channel cake to lessen the water content of the channel cake.
(1) Filtration technique
The manner in which the filtrate streams out is partitioned into open-stream filtration and dull stream filtration.
A. Open-stream filtration: Each channel plate is furnished with a industrial filter press manufacturers water spout on the lower outlet opening, and the filtrate streams out instinctively from the water spout.
B. Hidden stream filtration: the lower part of each channel plate is furnished with a fluid outlet channel opening, and the fluid outlet openings of a few channel plates are associated with structure a fluid outlet channel, which is released by a line associated with the fluid outlet opening underneath the plug plate.
(2) Washing technique
At the point when the channel cake should be washed, there are open stream single direction washing and two-way washing, dim stream single direction washing and two-way washing.
A. Single direction washing in open stream is that the washing fluid enters from the washing fluid delta opening of the plug plate, goes through the channel fabric and afterward through the channel cake, and streams out from the non-permeable channel plate, when the power source spout of the permeable plate is shut and the power source spout of the non-permeable plate is open.
B. Two-way washing is the washing fluid from the highest point of the plug plate on the two sides of the washing fluid into the opening has been washed two times, that is, the washing fluid first from one side of the washing fluid and afterward from the opposite side of the washing fluid, the power source of the washing fluid with the import is askew heading, so additionally called two-way cross washing.
C. Hidden single direction stream washing is that the washing fluid enters the punctured plate thusly from the washing fluid channel opening of the plug plate, wears the channel fabric and afterward goes through the channel cake and streams out from the non-punctured channel plate.
D. Dull stream two-way washing is that the washing fluid is washed two times in progression from the two washing fluid bay openings on the two sides over the stop plate, for example washing is washed from one side first and afterward from the opposite side, and the power source of the washing fluid is in the inclining bearing, so it is additionally called dim stream two-way cross washing.
(3) Filter fabric: channel fabric is a significant separating medium, the decision and utilization of channel fabric plays an unequivocal part in the sifting impact, the decision ought to be founded on the PH worth of the sifting material, strong molecule size and different variables to pick the fitting channel fabric material and gap to guarantee low filtration expenses and high filtration productivity, when utilizing, to guarantee that the channel fabric is level and not collapsed, the gap is unhindered.
