Vacuum disc filter machine

【Vacuum disc filter machineWorking principle: It is a solid-liquid separation device. The filter disk is driven by a speed regulating motor through a reducer and an open gear transmission, so that it rotates at a certain speed in a tank filled with slurry. When one of the filter fans of the filter disk is in the filtration adsorption zone, a pressure difference is formed on both sides of the filter medium by the action of a vacuum pump, causing the solid material to adsorb on the filter medium (filter cloth) and form a filter cake. The filtrate is discharged through the filtrate pipe and distribution head. When this filter fan separates from the slurry level and enters the dewatering zone, the filter cake is continuously separated from water by the vacuum suction force, and further discharged from the filtrate pipe and distribution head, causing the filter cake to dry. After entering the unloading area, the filter cake is unloaded from the filter disc using a reverse air blower and scraper, and falls into the discharge chute. It is transported away by the ore collection belt conveyor, and the entire operation process is carried out continuously.

【Vacuum disc filter machineProduct Features and Advantages

1. The fan-shaped filter plate has evenly distributed dehydration holes, reasonable porosity, and large rib size. It is made of high-strength engineering plastic, which increases its service life by 1-1.5 times.

2. The filtration area of the filtrate tube is large, and the abdominal area of the distribution head is large, which improves the pumping rate and filtrate discharge effect.

3. Wear resistant nylon monofilament or double-layer multifilament filter cloth is not easily clogged, significantly improves dehydration rate, and extends service life.

4. Multi point dry oil pump centralized automatic lubrication.

5. The automatic cleaning device for filter cloth maintains a good dewatering effect.

6. Horizontal forced variable speed mixing, with rubber and graphite packing and triple sealing of water pressure difference at the shaft end to ensure no slurry leakage.

7. The main transmission adopts continuously variable speed, which is adjusted according to the concentration and flow rate of the material (AC speed regulating motor or frequency converter), in order to achieve the ideal working effect.

8. Each plate is composed of 20 filter fan plates, which enhances the control of the filtration process and ensures uniform cake thickness.

9. The friction plate is made of special wear-resistant material boron cast iron, which combines rigidity and flexibility, has good sealing effect, and has a long service life.

10. The filtrate tube is made of high-strength wear-resistant ceramic composite steel pipe, which can increase the service life by more than 10 times.

11. Remove the upper and lower flanges from the interface between the filtrate pipe and the filter fan, and use mold positioning for direct welding to reduce 90% of possible air leakage points.

12. The arc-shaped groove is made of engineering plastic through one-time injection molding, which is corrosion-resistant and has good sealing performance.
