Well-known filter manufacturers at home and abroad
Thread Content
I would like to ask everyone: which are the well-known filter manufacturers, both domestically and internationally? Which manufacturers produce high-quality filtration equipment? It has a good reputation in the industry; it is mainly used for filtering hydroxides. Its properties are similar to those of iron hydroxide. After filtration, the filter cake needs to be slurried and filtered repeatedly until other impurities in the hydroxides are below 10 ppm. Do any of you have any suitable filters to recommend?
Vacuum Belt Filter – Yantai Tongxing in the Nuclear Industry； Plate and frame filter press — Jingjin Environmental Protection ； Piston push centrifuge — Chongqing Jiangbei Machinery, Xiangtan Centrifuge, Shanghai Chemical Machinery ； Horizontal spiral centrifuge – American brand Knight, and the domestic company that produces it is Chengdu Tiansheng Centrifuges. Regardless of the type of solid-liquid separation equipment chosen, the decision is mainly based on the properties of the material. Some devices have filtering and washing functions; is it not necessary to pulp the material first before washing?

What you need are vacuum filters and similar devices equipped with functions such as stirring and backflushing; these may require customization or being designed and manufactured by yourself. The Xiangtan Dye Chemical Factory used to have equipment of this kind. If the requirements are high and the company has sufficient funds, it might consider a siphon scraper discharge centrifuge, with an investment of around 500,000.

In my opinion, a candle filter can be used for this purpose. After the first filtration, when the pressure difference reaches the set value, backwashing is carried out: first, the liquid inside the tank is filtered under pressure, and then air is blown in to dislodge the filter cake, which is then discharged through the slag outlet at the bottom. The slurry is then re-introduced into the filter, and this process is repeated. It should be possible to determine the particle size distribution of various components in the medium by selecting an appropriate level of precision.
