1. Overview:

Vacuum rubber belt filter is a kind of extraction equipment developed on the basis of mobile belt filter, which is a kind of high-efficiency separation equipment used to separate various suspended solids of solid-liquid two-phase combination of rapid filtration and dehydration. It is widely used in mining, metallurgy, pharmaceutical, petroleum, coal, papermaking, electric power, environmental protection and other industrial sectors, and can separate iron concentrate uranium invasion liquid, pulping, gypsum, production resin, sewage treatment, etc., its main characteristics are:

1. High extraction efficiency: using horizontal filter surface and upper feeding, due to the action of gravity, the solid phase of large particles will first sink at the bottom to form a layer of filter aid layer, which reduces the blockage of the filter cloth, has low filtration resistance and high extraction efficiency.

2. The structure is reasonable: each component is made of anti-corrosion materials and anti-corrosion treatment, the main drive is driven by belt, and the vacuum box is made of corrosion-resistant materials, which has a long service life.

3. The thickness of the filter cake can be adjusted, the moisture content is small, and the removal is convenient: the thickness of the filter cake can be adjusted at will according to the needs of the material.

4. The filter cloth can be cleaned on both sides at the same time: the front and back sides of the filter cloth are equipped with water spray cleaning devices, which eliminates the blockage of the filter cloth and prolongs the service life of the filter cloth.

5. Flexible operation and low maintenance cost: in the production process, the thickness of the filter cake, the amount of washing water, the vacuum degree and the cycle time are adjusted at will to achieve the filtration effect. Because the filter cloth can work under harsh conditions and has a long service life, the maintenance cost and production cost are greatly reduced.

2. Structural features:

This machine is divided into left and right mobile phones (standing on the filter cake discharging end facing the body, the transmission is the left mobile phone on the left side, and the right mobile phone is reversed), the main frame, the discharging device, the main transmission roller, the driven roller, the washing device, the tensioning device, the deviation adjustment device, the automatic liquid discharge tank, the rubber belt, the filter cloth, etc., the frame is equipped with the mesh belt limiting roller and the correction device, in order to ensure that the mesh belt moves within the allowable range and deviates from the adjustment. The filter cloth is equipped with a deviation adjustment and correction device and a tensioning device at the same time. The use of high-strength rubber belt and filter cloth belt, both as a ring filter belt and a conveyor belt on the machine, when working, the material has a feeding device to distribute to the moving filter belt, under the action of vacuum to form a filter cake, in turn through filtration, washing, dehydration, cake unloading and filter belt washing to complete the cycle. Its structure is characterized by the vacuum box and the filter belt between the formation of a motion seal, the filter belt moves on the vacuum box, compared with the mobile type, it overcomes the mobile belt type every action, to remove the vacuum, the lack of energy consumption, to achieve continuous filtration, the production process of filtration, washing, dehydration, cake unloading, filter cloth cleaning, etc. can be completed in turn with the movement of the filter cloth, so that the filtration efficiency is improved.
