I. Outline
The casing is the essential piece of the channel press. The two closures are the plug plate and the squeezing head, and the shafts on the two sides are utilized to help the channel plate, the channel outline and the squeezing plate. To meet cleanliness necessities, the edge should be clad in hardened steel. Tempered 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 deadlocks to sit one finish of the channel push on the establishment.
The openings in the upper two corners are for the bay of washing fluid or press gas and the lower two corners are for the power source (dull stream construction 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 bar.
C, bar: is a heap bearing part, as per the prerequisites of the utilization of natural erosion, can pick inflexible PVC, polypropylene, hardened steel cladding or new enemy of consumption covering and other covering.
II. Squeezing system
Manual squeezing, mechanical squeezing, pressure driven 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 component 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 pole 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, and when it arrives at the current worth set by the defender, the engine cuts off the power and quits pivoting, on the grounds that the fiber bar and the proper fiber mother have a dependable self-locking twisting point, it can dependably guarantee the squeezing state during the functioning system.
C. Water driven squeezing: The pressure driven squeezing instrument comprises of a water driven station, chamber, cylinder, cylinder pole and a cylinder bar associated with the squeezing plate.
The construction of the water powered station associated with the Hafland card comprises of: engine, oil siphon, alleviation valve (to change the tension) switching valve, pressure measure, oil circuit, oil tank. At the point when the water driven squeezing apparatus is squeezed, the high strain oil is provided by the pressure driven station, and the part cavity shaped by the chamber and cylinder is loaded up with oil, when the tension 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 tension worth set by the help valve (shown by the pointer of the strain check), the channel plate, channel outline (plate and casing type) or channel plate (chamber type) is squeezed, and the alleviation 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 switching valve is turned around and the strain oil enters the pole hole of the chamber, when the oil tension can beat the grating filter press factory opposition of the squeezing plate, the squeezing plate begins to return. At the point when the strain arrives at the maximum furthest reaches of the tension measure, the power supply will be cut off and the oil siphon will quit providing power, as the interior and outer spillage of the oil circuit framework might make the tension drop, when it arrives at the lower furthest reaches of the tension check, 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, with the goal that the cycle can accomplish the impact of guaranteeing the squeezing power during the time spent sifting materials.
Three, the sifting component
The sifting component 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 stream 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 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 naturally from the water spout.
B. Hidden 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 beneath 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 slanting bearing, so additionally called two-way cross washing.
C. Covered single direction stream washing is that the washing fluid enters the punctured plate thus from the washing fluid delta opening of the plug plate, wears the channel material and afterward goes through the channel cake and streams out from the non-punctured channel plate.
D. Dim stream two-way washing is that the washing fluid is washed two times in progression from the two washing fluid gulf 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 slanting course, so it is additionally called dull 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 variables to pick the fitting channel fabric 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 gap is unhindered
