Closed Plate Filter

Main Structure


The filter body is composed of a shell, filter plates, cover-opening mechanism, slag discharge system, and other components. The filter plates are made of multiple layers of stainless steel mesh and are mounted on the central collection pipe. The disassembly and cleaning are very convenient.

During filtration, the liquid to be filtered, containing filter aids, is introduced into the filter, causing a filter cake to form on the filter mesh. This filter cake provides a vast number of fine channels, allowing the liquid to pass through the micropores in the cake for filtration.

Filtration Principle

• Metal wire mesh + filter aid + pressure.
• The filter plate is composed of stainless steel multi-layer wire mesh and a framework.
• The filter is compatible with various filter aids (such as diatomaceous earth, white clay, bentonite).
• Under differential pressure, the filter aid forms a filter cake on the mesh plate, which enables normal filtration.

Product Features

• The uniquely designed filter mesh plate eliminates the need for filter paper and cloth, significantly reducing filtration costs.
• Fully enclosed filtration operation ensures no contamination and no material loss.
• The automatic vibration slag discharge device enables automated continuous operation.
• Automatic discharge valves greatly reduce the labor intensity of workers.
