Special nano-filter plate for filter press

Abstract

The invention relates to a special nano-filter plate for a filter press, which has the advantages of ultra-strong dirt resistance, ultra-strong wear resistance, ultra-strong electrostatic resistance and ultra-strong durable efficacy. The special nano-filter plate comprises a filter plate, wherein the surface layer of the filter plate is a nano-layer. The invention has the concrete advantages that: the special nano-filter plate has ultra-strong dirt resistance, has a smooth and exquisite surface, can not adsorb dust and grease dirt easily, is easy to clean and enables the squeezed filter cake to automatically fall off from the surface of the nano-filter plate, and the nano-surface of the special nano-filter plate has good anti-dirt characteristic; the special nano-filter plate has ultra-strong wear resistance, the wear resistance of the surface of the filter plate can be obviously improved, and extruding scratches can not be generated easily; the special nano-filter plate has ultra-strong electrostatic resistance, can effectively eliminate the electrostatic phenomenon, and can not adsorb dust particles easily; the special nano-filter plate has superior acid resistance and alkali resistance and high weather resistance; and the surface of the special nano-filter plate is water-proof, can resist grease dirt, is simple and convenient to clean and is nearly not cleaned with water, thereby greatly saving the water resources.

Description

technical field [0001] The invention relates to a special nano-filter plate for a filter press which not only has super anti-pollution, super wear-resistance and super anti-static, but also has super strong and long-lasting efficacy, and belongs to the field of filter plate manufacturing for filter presses. Background technique [0002] CN1399576A, name "filter plate of filter press", a filter press (1) for filtering suspension has a plurality of filter plates (1M, 1K) arranged in parallel with each other and relatively movable, they are in the filter position It can be compressed into a filter plate group, and the filter plate group has a filter cavity (23) with at least one filter cloth (7M, 7K) between every two filter plates (1M, 1K). When two adjacent filter plates (1M, 1K) are in the slag discharge position, there may be a slag discharge interval between them, so that the filter residue adhered to the filter cloth (7K) can be removed. Each filter cavity (23) is provid...

AI Technical Summary

Problems solved by technology

[0008] The deficiencies in the background technology of the first five articles above are as follows: First, the formed filter cake firmly adheres to the rubber membrane or filter plate after the material is squeezed by the rubber membrane or the filter plate and cannot fall off by itself, so a special powerful rapping mechanism is required Vibrate strongly on both sides of the core plate connected with the rubber membrane to force the filter cake to separate from the rubber membrane or filter plate. The powerful rapping mechanism can force most of the filter cake to fall off from the rubber membrane or filter plate, but at the same time it also causes internal damage to the diaphragm filter plate, and its service life is greatly shortened; The rubber membrane is cleaned by a special cleaning mechanism, which not only wastes water resources, but also takes a lot of work and time, which directly affects the pressing efficiency of the filter press; the third is that the anti-fouling property is poor, and a large amount of clean water is needed for washing, and the waste of water resources is very large; The wear resistance is poor, because the extrusion friction is formed between the filter material and the diaphragm, so the amount of wear is large, resulting in rapid wear of the filter plate; fifth, not only does it not have antistatic performance, but it is easy to generate static electricity, which directly affects material quality

[0009] The sixth part of the background technology mentioned above solves the problem that the ceramic filter plate is not blocked, which is only applicable to ceramic filters, not to filter presses.
