Rubber belt vacuum filter is a new generation of separation equipment!

Rubber belt vacuum filter, also known as fixed belt vacuum filter, is a new degree of automation of the new solid-liquid separation equipment. The equipment is usually composed of rubber filter, vacuum box, drive roller, tape support platform, feed hopper, filter cloth deviation device, filter cloth washing device and rack and other components, is to make full use of material gravity and vacuum suction to achieve solid Liquid separation of high efficiency separation equipment.
Rubber belt vacuum filter to filter cloth as a filter medium, the use of the overall ring rubber belt as a vacuum chamber. Ring tape by the motor drag continuous operation, the filter cloth spread on the tape with the synchronous operation, tape and vacuum sliding contact (vacuum chamber and tape with a ring between the friction band and water into the water seal), the slurry from the distributor evenly To cloth on the filter cloth. When the vacuum chamber is connected to the vacuum system, a vacuum suction zone is formed on the tape. The filtrate is passed through the filter cloth through the transverse grooves on the tape and enters the vacuum chamber from the small holes. The solid particles are trapped on the filter cloth to form the filter cake. The liquid entering the vacuum chamber is discharged through the gas-water separator. As the rubber belt moves, the formed filter cake enters the filter cake washing zone and the suction area in turn, and finally the filter cloth is separated from the tape, The cake is unloaded. The filter cloth for removing the filter cake is regenerated after cleaning, and then passed through a set of backup rollers and correction devices to re-enter the filter area to start a new filtration cycle. Compared with the mobile chamber vacuum filter, the rubber belt vacuum filter overcomes the shortcomings of the mobile chamber filter with every vacuum and the high energy consumption, and realizes the continuous operation in the true sense , Continuous filtration, the material from the expected, vacuum dehydration, filter cake washing, slag to filter cloth cleaning, can be carried out without interruption.
Rubber belt vacuum filter structure of the most prominent features:
First, the use of a fixed vacuum box, tape moving on the vacuum box, vacuum box and tape designed between an annular friction belt and water sealed, vacuum box and tape constitute a motion seal between the structure, sealed water can be used as a sealing device Lubricant can also be used as a coolant, while forming a very effective vacuum seal.
Second, in the way of supporting the tape, the use of air-cushion support or water film support, tape floating on the air or liquid film, can effectively reduce the friction of the tape running resistance.
Third, in the overall structure, the use of a removable frame structure, to ensure that the installation and maintenance of ring tape and equipment maintenance.
The rubber belt vacuum filter has the advantages of high filtration efficiency, large production capacity, good washing effect, wide application range and simple operation. It is widely used in the fields of fine chemical industry, mineral processing, metallurgy, paper making, food and medicine, environmental protection and so on. And everyone agreed that the effect is good.
