China Disc Type Vacuum Filter for Solid-Liquid Mineral Slurry Separation - Leading Suppliers & Factory Solutions
Feature
The dehydration holes of the fan-shaped filter plate are evenly distributed, with a reasonable porosity, large rib size, and made of high-strength engineering plastic, which increases the service life by 1 to 1.5 times.
The filtration area of the filtrate pipe is large, and the area of the distribution head and abdominal cavity is also large, which improves the air extraction rate and the effect of filtrate discharge.
Wear-resistant nylon monofilament or double-layer multifilament filter cloth increases the dehydration rate and is less prone to clogging, thus prolonging the service life.
Centralized automatic lubrication by multi-point dry oil pumps.
The automatic filter cloth cleaning device maintains its excellent dehydration effect.
Horizontal forced variable-speed stirring, the shaft end adopts rubber and graphite packing and triple sealing with water pressure difference to ensure no slurry leakage.
The main drive features stepless speed regulation, which is adjusted according to the concentration and flow rate of the material (AC speed-regulating motor or frequency converter) to achieve the desired working effect.
Each plate is composed of 20 filter fan plates, which enhances the control of the filtration process and ensures uniform cake thickness.
The friction plates are made of specially designed wear-resistant boron cast iron, which combines rigidity and flexibility, has a good sealing effect and a long service life.
The filtrate pipe is made of high-strength wear-resistant ceramic composite steel pipe, which increases the service life by more than 10 times.
The upper and lower flanges at the interface between the filtrate tube and the filter fan are removed, and direct welding with mold positioning is adopted, reducing the possible air leakage points by 90%.

Frequently Asked Questions
What are the main advantages of the fan-shaped filter plate?
The dehydration holes are evenly distributed with reasonable porosity and large rib size. Made of high-strength engineering plastic, it increases the service life by 1 to 1.5 times.
How does the equipment achieve a high air extraction rate?
It utilizes a large filtration area in the filtrate pipe, as well as a large area in the distribution head and abdominal cavity, which significantly improves both air extraction and filtrate discharge.
What type of filter cloth is used and why?
It uses wear-resistant nylon monofilament or double-layer multifilament filter cloth. This material increases the dehydration rate, is less prone to clogging, and prolongs the overall service life.
How is the operating speed of the main drive controlled?
The main drive features stepless speed regulation. It can be adjusted based on the concentration and flow rate of the material using an AC speed-regulating motor or frequency converter.
What material is used for the filtrate pipe?
The filtrate pipe is constructed from high-strength wear-resistant ceramic composite steel pipe, which increases its service life by more than 10 times.
How does the design prevent air and slurry leakage?
The shaft end adopts rubber and graphite packing with triple sealing to prevent slurry leakage. Additionally, flanges at the filtrate tube interface are removed in favor of direct welding with mold positioning, reducing air leakage points by 90%.
