Good Quality Positive pressure filter - Positive pressure filter – Weitai Detail:

The positive pressure filter is a filter placed in a closed pressurized warehouse. A scraper conveyor is arranged under the falling slot of the disc filter, and a discharge device is installed at the head. The filtered suspension is fed into the tank of the filter by the feed pump, and the pressurized chamber is filled with a certain pressure of compressed air. On the filter disc, a pressure difference is formed between the filter valve and the air-water separator through the atmosphere. Under the action of the internal pressure in the pressure chamber, the liquid in the tank is discharged through the filter medium immersed in the suspension, and the solid particles are collected on the filter medium to form a filter cake. With the rotation of the filter disk, the filter cake is dried. After the moisture is reduced, it is discharged to the conveyor in the discharge area of the distribution valve and collected by the conveyor into the discharge device. In this continuous operation, when a certain amount is reached, the discharge device is intermittently discharged out of the machine and the entire work The process is automatic.

It is widely used for solid-liquid separation of non-ferrous metallurgy, ferrous metallurgy, primary coal slime, chemical industry (alkali plant), flotation dewatering of coal, and light industry, building materials, and urban sewage (mud).

This kind of horizontal pressure filter is applicable in solid-liquid separation in nonferrous metallurgy, black metallurgy, coal, chemical, alkali, construction material, clean coal dehydration, and urban sewage treatment industries.

The filter part of positive pressure filter is designed to be placed in a sealed pressure vessel. Under the chute of the disc filter, we have set a scraper conveyor. The discharging device is mounted at the head of the pressure filter. The suspension enters the filter vessel under the support of the feeding pump. Some compressed air with certain pressure is filled into the pressure chamber. Therefore, a pressure difference is generated with the distribution valve and the gas-water separator, and the liquid will be exhausted through the filter media under the pressure of the chamber. The solid particles will be collected on the medium to form a filter cake. As the rotation of the filter disc, the filter cake is dried and sent to the scraper conveyor, and then collected to a discharging device, which works intermittently to discharge the filter cake when a certain amount of cakes have been accumulated.
