Sifting component
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.
