DU Rubber Belt Vacuum Filter

Equipment Introduction

The DU rubber belt vacuum filter is a device that achieves solid-liquid separation through the suction force of vacuum negative pressure. Structurally, the filtration section is arranged along the horizontal length direction, allowing for continuous completion of processes such as filtration, filter cake washing, drying, cake discharge, and cloth regeneration. The equipment boasts high filtration efficiency, large production capacity, effective washing, low filter cake moisture content, flexible operation, and low maintenance costs.

Especially suitable for suspensions of slurry with coarse solid particle filtration, high density, and filter cakes requiring multiple washes.Is used in a wide range of vacuum filter equipmentPlease provide the Chinese content you would like translated into American English.Wide equipmentWidely applicable in metallurgy, mining, chemical industry, papermaking, food, and more.FGD Flue Gas Desulfurization、Solid-liquid separation in the fields of environmental protection.

Operating Principle:

The equipment features a fixed vacuum box design. The annular rubber belt is continuously driven by a reducer on the vacuum box. The filter cloth is laid on the belt and runs synchronously. The belt contacts and forms a water-tight seal with the friction belt on the sliding platform of the vacuum box. The slurry is evenly distributed on the filter cloth by a distributor. When the vacuum chamber is connected to the vacuum system, a vacuum filtration zone forms on the belt. The filtrate passes through the filter cloth, collects in the transverse grooves on the belt, and enters the vacuum chamber through small holes, while solid particles are retained on the filter cloth to form a filter cake. The liquid entering the vacuum chamber is discharged through a steam-water separator. As the...Rubber BeltThe feed moves, and the formed filter cakes sequentially enter the cake washing area.DehydratedZoneThe final filter cloth is separated from the tape, and the filter cake is discharged by a scraper at the discharge roller. The filter cloth used to discharge the filter cake is cleaned and recycled, then re-enters the filtration zone after passing through a set of supporting rollers and a skew correction device, ready to begin a new filtration cycle.
