I. Outline
The edge is the essential piece of the channel press. The two closures 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. To meet cleanliness prerequisites, the casing should be clad in treated steel. Hardened steel cladding innovation is accessible for reference and is of a quality that addresses the issues of European clients.
A. Push plate: It is associated with the stalemates to sit one finish of the channel push on the establishment.
The openings in the upper two corners are for the gulf of washing fluid or press gas and the lower two corners are for the power source (dim stream design or filtrate outlet)
b. Squeezing plate: used to press the channel plate and channel outline, the rollers on the two sides are utilized to help the squeezing plate moving on the track of the shaft.
C, shaft: is a heap bearing part, as per the prerequisites of the utilization of ecological consumption, can pick unbending PVC, polypropylene, hardened steel cladding or new enemy of erosion covering and other covering.
II. Squeezing instrument
Manual squeezing, mechanical squeezing, water powered squeezing.
A、Manual squeezing: the screw type mechanical jack is utilized to push the squeezing plate to press the channel plate.
B. Mechanical squeezing: the squeezing system comprises of engine (furnished 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 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, and when it arrives at the current worth set by the defender, the engine cuts off the power supply and quits turning, on the grounds that the fiber pole and the decent fiber mother have a solid self-locking winding point, it can dependably guarantee the squeezing state during the functioning system.
C. Pressure driven squeezing: The water powered squeezing system comprises of a water driven station, chamber, cylinder, cylinder bar and a cylinder bar associated with the squeezing plate.
The design of the water driven station associated with the Hafland card comprises of: engine, oil siphon, alleviation valve (to change the strain) 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, and the part depression shaped by the chamber and cylinder is loaded up with oil, when the strain is more prominent than the contact 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 alleviation valve (shown by the pointer of the tension measure), the channel plate, channel outline (plate and casing type) or channel plate (chamber type) is squeezed, and the help valve begins to dump, right now, the power supply of the engine is cut off, and the squeezing activity is finished. At the point when the squeezing activity is finished, the turning around valve is switched and the tension oil enters the pole depression of the chamber, when the oil strain can beat the grating opposition 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 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,largest filter press manufacturer the power supply will be turned on and the oil siphon will begin providing oil, the tension will arrive at When the strain arrives at as far as possible, the power supply is cut off and the oil siphon quits providing oil, so the cycle can accomplish the impact of guaranteeing the squeezing power during the time spent separating materials.
Three, the separating system
The separating system is made out of channel plate, channel outline, channel fabric and squeezing stomach, the two sides of the channel plate are covered by channel material. 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 in light of the fact 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 strategy
The manner in which the filtrate streams out is separated 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 naturally from the water spout.
B. Disguised stream filtration: Each channel plate is outfitted with a fluid outlet channel opening under, and the fluid outlet openings of a few channel plates are associated with structure a fluid outlet channel.
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 material 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 inclining bearing, so likewise called two-way cross washing.
C. Covered single direction stream washing is that the washing fluid enters the punctured plate thusly from the washing fluid bay 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 askew bearing, 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 material plays an unequivocal part in the filtration impact, the decision ought to be founded on the PH worth of the channel material, strong molecule size and different elements to pick the suitable channel fabric material and gap to guarantee low filtration expenses and high filtration productivity, when utilizing, to guarantee that the channel material is level and not collapsed, the gap is unhindered
