Product Description
Filter mechanism
A filter plate consists of a filter plate, a filter frame, a filter cloth and a pressing diaphragm. On both sides of the filter plate, a filter cloth is covered and a press diaphragm needs to be configured. A group of filter plates is composed of a diaphragm plate and a side plate. Two sides of the diaphragm board are covered with rubber diaphragms, and the outer side of the diaphragm is covered with filter cloth, and the side plate is an ordinary filter plate. The material from the thrust plate enters the filter chamber, and the solid particles are intercepted in the filter chamber because the size of the particle size is larger than the filter medium (filter cloth), and the filtrate is outflow from the outlet of the liquid outlet under the filter plate. When the filter cake needs to be squeezed, the compressed air or steam can be used in addition to the compressed air or steam. The water of the filter cake is washed through the washing mouth, and the moisture content of the filter cake is reduced.
(1) filtering method
The filtrate flow way is clear flow filtration and undercurrent filtration.
A, open flow filtration: there is a water nozzle on the bottom outlet of each filter plate, and the filtrate flows out of the water nozzle intuitively.
B, dark flow filtering: the outlet of each filter plate is provided with a liquid channel hole, and the outlet of several filter plates is Kong Liancheng a liquid outlet, which is discharged by a pipe connected by the outlet of a fluid hole below the thrust plate.
(2) the way of washing
When the filter cake is washed, there should be one way washing and two-way washing, underflow one-way washing and two way washing.
A, open flow one-way washing is, the lotion from the thrust plate of the lotion into the hole into the hole, through filter cloth through filter cake, through the filter cake, out of the hole filter plate, at this time the outlet of the hole plate is closed, the outlet of the nozzle is open.
B, open flow two-way washing is, washing liquid from the top of the washboard on both sides of the lotion into the hole two times successively washing, that is, washing liquid first from one side washing and then washing from the other side, the export of lotion is diagonal direction, so it is called two-way cross washing.
C, the undercurrent one-way flow is to wash the liquid into the perforated plate from the washing liquid inlet of the thrust plate, pass through the filter cloth and pass through the filter cake, and flow out of the non porous filter plate.
D, dark current two-way washing is washing liquid from the top of the side of the two washing liquid two times successively washing, that is, washing first from one side, then washing from the other side, the outlet of the lotion is diagonal direction, so it is also called the two-way cross washing of dark current.
(3) filter cloth: filter cloth is a main filter medium, the selection and use of filter cloth has a decisive effect on the filtering effect. When selecting the filter material and the diameter of the solid particle, the suitable filter material and pore size should be selected to ensure the low filtration cost and high filtration efficiency. Without discount, the aperture is unimpeded.
