Parts of the channel press
The design of the channel press is comprised of three sections.
Channel press outline
The edge is the essential piece of the channel press. The two finishes are the plug plate and the squeezing head, and the pillars 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 bay opening, and there are four openings at the four corners, the openings at the upper two corners are the washing fluid or squeezing gas delta, and the lower two corners are the power source (dull stream design 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 bar: It is a heap bearing part, which can be covered with hard PVC, polypropylene, treated steel cladding or new enemy of erosion covering as per the necessities of hostile to consumption in the utilization climate.
Squeezing component of the channel press
Manual squeezing, mechanical squeezing, water powered 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 system comprises of engine (outfitted with cutting edge over-burden defender) minimizer, gear installment, screw and fixed nut. When squeezing, the engine is turning, driving the minimizer and stuff installment, causing the fiber bar to pivot in the decent 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 pivoting, on the grounds that the fiber bar and the decent fiber mother have a solid 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 driven squeezing: water powered squeezing system comprises of a water powered station, oil chamber, cylinder, cylinder bar and cylinder bar and squeezing plate filter press company associated with the Havlan card water powered station structure comprises of: engine, oil siphon, help valve (to change the strain) switching valve, pressure check, 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 hole 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 strain esteem set by the help valve (shown by the pointer of the strain measure), the channel plate, channel outline (plate and casing type) or channel plate (chamber type) is squeezed, the alleviation valve begins to dump, as of 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 tension oil enters the pole pit of the chamber, when the oil strain can defeat the grating obstruction of the squeezing plate, the squeezing plate begins to return. At the point when the strain arrives at the furthest reaches of the tension check, the power supply will be cut off and the oil siphon will quit providing power, as the inner and outer spillage of the oil circuit framework might make the tension drop, when it arrives at the lower furthest reaches of the tension measure, the power supply will be turned on and the oil siphon will begin providing oil, the strain will arrive at When the strain arrives at as far as possible, the power supply will be cut off and the oil siphon will quit providing oil, in order to accomplish the impact of guaranteeing the strain during the method involved with separating materials.
Sifting component of the channel press
The sifting component comprises of a channel plate, a channel outline, a channel fabric 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 fabric), 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 stream washes away the water in the channel cake to diminish the water content of the channel cake.
(1) Filtration technique
The manner in which the filtrate streams out is isolated into open-stream filtration and dim stream filtration.
A. Open-stream filtration: Each channel plate is furnished with a 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 strategy
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 gulf 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 slanting course, so likewise called two-way cross washing.
C. Hidden single direction stream washing is that the washing fluid enters the punctured plate thus from the washing fluid channel opening of the plug plate, goes through the channel material and afterward 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 askew course, so it is additionally called dim stream two-way cross washing.
(3) Filter fabric: channel material is a significant channel media, the decision and utilization of channel fabric plays a definitive part in the filtration impact, the decision ought to be founded on the PH worth of the channel material, strong molecule size and different variables to pick the proper channel material and gap to guarantee low filtration expenses and high filtration proficiency, when utilizing, to guarantee that the channel material is level and not collapsed, the opening is unhindered.
