What is a rotary filter?

A vacuum rotary filter is a solid-liquid separation device that utilizes vacuum suction to continuously perform filtering, washing, unloading, and other operations during the rotation of a cylinder. Here is a specific introduction:

Working principle: The outer wall of the drum has small holes and is wrapped with filter cloth. The interior is divided into several fan-shaped grids that are not connected to each other, and connected to the distribution head through the holes on the hollow shaft. The lower half of the drum is immersed in the filter slurry, while the upper half is exposed outside the tank. When the drum rotates, the fan-shaped grid passes through different areas in sequence. In the filtration zone, connected to vacuum, the filtrate passes through the filter cloth into the fan-shaped grid and is discharged; Next, in the drying area, continue to vacuum dry the remaining filtrate and filter cake; Then in the washing area, the washing water is sprayed onto the filter cake, and the washing water is sucked in and discharged; Finally, in the unloading area, it is connected to compressed air, and the filter cake is blown loose and peeled off by a scraper. After that, the filter cloth can be cleaned and enter the next cycle.

Product advantages

Rotating filters have outstanding advantages in the field of continuous solid-liquid separation. With the collaborative operation of vacuum negative pressure and rotating structure, this equipment not only achieves efficient and stable operation, but also forms differentiated competitiveness in space utilization, cost control and safety assurance, providing reliable technical solutions for industrial production.

FAQ

How to solve the problem of filter cloth clogging?

Due to the high number of solid particles in the filtrate, insufficient pre-treatment, or untimely cleaning of the filter cloth, or compatibility between the material pore size and the material department, screening and other pre-treatment steps can be added. The filter cloth should be regularly cleaned using high-pressure water chemical method, and the filter cloth should be selected according to the material characteristics.

How to deal with high moisture content in filter cake?

During work, there are often situations where the drum is immersed in the filtrate for a long time, the vacuum degree is insufficient, or the filter cake is not washed sufficiently. It can reduce the feeding speed, lower the immersion degree, improve the vacuum degree, or optimize the washing process.

How to solve the problem of poor slag discharge in equipment?

The reason is due to the small design of the slag discharge outlet, wear of the scraper, or excessive viscosity of the filter cake. The design of the slag discharge outlet can be improved, the scraper can be replaced, or the viscous material can be pre treated to reduce viscosity, which can ensure smooth slag discharge of the material.

Can high viscosity liquids be filtered?

This depends on the design and performance of the equipment. The rotating filter is specially designed to handle liquids of certain viscosity, but high viscosity liquids may affect filtration efficiency and may require pre-treatment measures such as preheating and dilution.
