Has anyone ever built a suction filtration tank?
Thread Content
Has anyone ever worked with a suction filtration tank? There is a filter plate in the middle of the equipment, and the space below the filter plate is evacuated using a vacuum pump. Should the space below the filter plate be designed for negative pressure? If so, wouldn’t the filter plate become too thick?
I roughly understand the design: below the filter plates, negative pressure is applied, but the filter plates are supported by steel pipes between them, which allows the thickness of the filter plates to be relatively smaller
It doesn’t need to be very thick, as the purpose of using a vacuum filtration tank is to separate solids from liquids. When the liquid content in the material reaches a certain level (which depends on the particle size and other physical properties of the material), the vacuum level will no longer increase. Generally, its vacuum level is relatively low; one can look up some materials to learn more about it in detail. My previous workplace used fiberglass filter plates, which had a decent service life; their thickness was around 10 millimeters.
