Ultra-dry filtering machine and filtrating method thereof

Abstract

The invention relates to an ultra-dry filtering machine and a filtrating method thereof. The ultra-dry filtering machine comprises a bed body and walls respectively arranged at the left side and the right side of the bed body. According to the invention, a slide track is laterally arranged on the bed body; a cylinder is arranged above the slide track; the bottom of the cylinder is installed on the slide track via a sliding block in a sliding way; pistons are respectively arranged on the left side and the right side in the cylinder; the left piston is connected with the left wall; a first hydraulic cylinder is connected to the right wall of the cylinder; the right piston is connected with a hydraulic rod of the first hydraulic cylinder; multiple filtering plates are axially distributed inside the cylinder; mud-cutting mechanisms are arranged between the filtering plates on two sides and the pistons on corresponding sides and between adjacent filtering plates. According to the invention, a mud-cutting net is arranged between the filtering plates, so as to enlarge gaps between the filtering plates while triggering the mud-cutting net to cut off solids between the filtering plates, thus solving the difficulty of mud removing of the prior art.

Description

technical field [0001] The invention relates to an ultra-high dryness filter and a filtering method. Background technique [0002] The main function of the filter press is to separate the solid-liquid mixture. The more thorough the separation, the lower the moisture content of the solid produced, the better the effect. The application number is: 201110078673.5 discloses a high-dryness filter and method, although the solid moisture content of the filter can reach within 60%, there are still defects that can be improved: 1. The water inlet on the cylinder body is directly arranged on the On the cylinder body, the strength of the cylinder body is affected, and the service life is shortened; 2. The method used leads to uneven dryness of the filter residue, the filter cloth is easy to plug, and it is difficult to clean. The filter residue is closely adhered to the filter cloth and other structures after high pressure. Difficult to remove mud. Unable to achieve automatic des...
