Details Introduction

Rubber belt vacuum filter is an efficient separation equipment that uses filter cloth as the filtering medium, fully utilizes material gravity settling and vacuum suction to achieve solid-liquid separation.

Working Principle

The device adopts a fixed vacuum box, and the circular rubber belt is continuously driven by a motor on the vacuum box. The filter cloth is laid on the tape and runs synchronously with it. The tape contacts the friction belt on the vacuum box slide table and forms a water sealed structure. The slurry is evenly distributed on the filter cloth by a fabric spreader. When the vacuum chamber is connected to the vacuum system, a vacuum filtration zone is formed on the tape. The filtrate passes through the filter cloth, collects through the transverse grooves on the tape, and enters the vacuum chamber through small holes. Solid particles are trapped 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 belt moves, the formed filter cake enters the filter cake washing area and the stage drying area in sequence. Finally, the filter cloth and tape separate, and the filter cake is discharged by a scraper at the discharge roller. The filter cloth from which the filter cake is unloaded is regenerated after cleaning, and then enters the filtration zone again after passing through a set of support rollers and correction devices, starting a new stage of filtration.

Characteristic

1. Large processing capacity, capable of continuous operation for 365 days.

2. Low failure rate and low maintenance cost (small vacuum loss).

3. The filter cake has low moisture content and the filtrate has low solid content, which can be directly discharged or reused.

4. Modular structure, easy operation and maintenance.

5. Adopting PLC+touch screen+automatic valve control, with high degree of automation, it can achieve unmanned operation.
