Pneumatic Self-cleaning Filter

Description

The pneumatic scraper type self-cleaning filter automatically removes the particulate impurities on the surface of the filter element through an efficient mechanical scraping method. It can perform continuous online filtration on a single machine, without producing filtration consumables, and without frequent manual cleaning. It is suitable for general and high-viscosity liquid filtration.

Traditional manual filters are frequently blocked when filtering viscous materials and soft impurities, and customers are forced to choose large filters or perform frequent backwashing, which requires large investment, heavy work, and serious material waste. Pneumatic scraper type self-cleaning filter can easily solve such problems, always keep the filter element clean, discharge slag liquid with high impurity concentration and small material waste.

Working Principle

The slurry flows top-down from the filter inlet, and flow to outlet through the surface of the filter element. Particles larger than the slot of the filter element are intercepted inside the filter element, and some impurities are stuck on the inner surface of the filter element to form a filter cake.
At a certain thickness, the cleaning device is activated, and the cylinder makes the circular scraper to push the filter cake into the filter cake collection cavity at the bottom of the filter. When a certain amount of filter cake accumulates in the collection cavity, the drain valve is regularly opened to remove the liquid containing high concentration impurities. The residual liquid can be recycled or directly discharged.
No frequent manual cleaning is required, suitable for continuous production conditions with high impurity content. Traditional manual filtrations are frequently blocked when filtering viscous materials and soft impurities. Customers are forced to choose large filters or frequently backwash device, which requires large investment, heavy work, and materials waste.
The filter is gradually replacing traditional manual filters such as vibrating screens, bag filters, basket filters, and some backwashing self-cleaning filters in many fields due to its significant technical advantages and low life cycle cost.

Model Selection

Advantages

Surface slot width is accurate, deviation is as small as 5 microns.
Main body 304,316L, 2205 material, excellent corrosion resistance.
V type slot, not easy to block impurities, and maintain stable flow for a long time.
The outer and inner surfaces are smooth and easy to scrape, with minimal wear on the scraper.
Filtrating tricky impurities, such as sludge impurities, soft agglomerated impurities, etc.
The surface is specially hardened and wear-resistant, which significantly prolongs the lifetime.
High-strength structure, the slot does not deform when the pressure difference rises.
Tolerate high-intensity forward and reverse pressure.
After actual verification, the filtering effect is outstanding, the filter screen is clean not easy to wear out.
