Hydraulic system of diaphragm filter, when related to hydraulic system of plate frame filter, unsealed part is hydraulic device.Since the hydraulic unit adopts a double-cylinder and screw extension structure, the hydraulic system seal effect is reduced if the two-cylinder piston seal is slightly problematic, or the screw arm and bottom nozzle gap is 1 mm,, which not only causes a large amount of hydraulic fluid to overflow, which also causes enough pressure to affect the operation of the entire equipment.
Diaphragm press filter room, I believe that as long as anyone has seen a horizontal press, you will know the important part of the plate frame press-filter room, which is a separate independent filter plate.Filfilters are placed in the middle and the device then provides strong pressure to get them into the filter chamber.It is primarily responsible for filtering the separation.When it works, it is filled with filtrates, and their internal energy is still high.If there is a slight position in the filter chamber, it can not be sealed, which is sufficient to cause insufficient internal pressure in the filter chamber.High, resulting in the filter fluid can not flow in the normal filtration path, thus affecting the work efficiency and quality of the equipment.In addition, the continuous penetration of the filtered liquid from the airtight places, which not only reduces the working quality of the equipment, but also increases the futility of the equipment, leading to the waste of the equipment.Therefore, it can be seen that the filter chamber should be sealed for the press to operate normally.
The diaphragm filter has the advantages of high pressure pressure, good corrosion resistance, convenient maintenance and high reliability.It is the choice of customers in metallurgy, gas, paper, coking, pharmaceutical, pharmaceutical, food, brewing, fine chemicals and other industries.The main difference between the diaphragm filter and the ordinary box filter is that two elastic films are added (the composite rubber diaphragm is an integral diaphragm) on both sides of the filter plate).During operation, when the feed is completed, the high pressure fluid medium is injected into the membrane and expands the entire membrane to filter the filter cake to further dehydrate the filter cake, which is pressure filtration.
The diaphragm filter plate adopts an intermediate feed separation tube, with the obvious advantage that the diaphragm filter can be formed during the filtration process, and the formed filter cake can be uniformly formed in the middle of the filter plate and formed.The finishing is accomplished by the secondary extrusion of the diaphragm press.If the half-angular inlet separation tube is used, it not only increases the irregularities of the filter cake formation, but also reduces the feed amount, thus affecting the efficiency of the membrane filter.The membrane filter realizes the filtration process of dehydration, which can ensure the good filter filtration effect and greatly reduce the water content of the filter cake.After the end of the adding process, filter the filter cake, improve the dehydration efficiency of the whole machine, increase the drying degree of the filter cake, reduce pollution, reduce labor, and even in some processes, can eliminate the drying process.If the blowing operation is added before and after suppression, the moisture content of the filter cake can be further reduced.
