Constant volume diaphragm type filter press

Abstract

The invention discloses a constant volume diaphragm type filter press which comprises brackets, clamping screw rods, positioning blocks, filter press units, pressing screw nuts, and the like, whereinthe filter press units comprise squeezing components and filtering components; the squeezing components comprise first frames, first partition plates, support bases, piston holes, piston rods, diaphragm covers, diaphragm cushion plates, diaphragm fasteners, diaphragms and exhaust holes; and the filtering components comprise second frames, second partition plates, filtering plates, filtering cloth,feeding holes, dreg discharge holes and liquid outlet holes. By adopting the technical scheme of the invention, repeated opening and closure of the filter press units are not needed in the filter press process, so that the production efficiency can be improved; and the whole filter press units are at a normally closed state, so that a material liquid can be prevented from being splashed out whenthe filter press units are opened and closed, and body damage to production operators can be avoided.

Description

technical field

[0001] The invention relates to the technical field of filter presses, in particular to a constant-volume diaphragm filter press. Background technique

[0002] In industrial production, filter presses are usually used as the main filtration equipment in the solid-liquid separation process. The filter press used in the prior art scheme usually needs to unload the filter cake after completing a filtration cycle, and the filter plates are pulled apart one by one by the plate puller, so that the filter cake falls and unloads from the filter chamber formed by the filter plates, thereby achieving purpose of filtering. As the filter area of ​​the filter press increases, the number of filter plates increases, and it will take more time to pull the filter plates one by one, which seriously reduces the production efficiency. And every time a filtration cycle is completed, the filter plate needs to be re-pressed. Frequent opening will cause damage to the seal, which i...
