Problems solved by technology

[0005] 2. Due to the regular cleaning method, the slag adsorbed on the filter cloth for a long time makes it difficult to clean the filter cloth, and the filter holes of the filter cloth are more and more blocked during the two cleaning periods, resulting in a gradual decrease in filtration efficiency. reduce
[0006] 3. For materials with fine particle size and high viscosity, it is necessary to stop frequently to clean the filter cloth, resulting in low filtration efficiency and poor effect

Embodiment Construction

[0017] The present invention is described in further detail by the following examples.

[0018] see figure 1 , figure 2 , image 3 As shown, a filter cloth cleaning device suitable for vacuum filters and pressurized filters consists of a filter cloth 1, a discharge scraper 2, a spray pipe 3, a nozzle 4, a knife seat 5, a water pipe 6, a fixed plate 7 and a base It consists of 8 seats. There are filter cloth cleaning devices with symmetrical structure on both sides of the filter cloth 1. The structure of the cleaning device on each side is as follows: a vertical metal knife seat 5 is welded on the fixed plate 7 along the length direction of the plate. There is a row of equidistant round through holes on the lower side of the shower pipe 3, and a nozzle 4 with an opening downward and oblique to the filter cloth 1 is threaded on each round through hole, and the top of the metal knife holder 5 is welded on a horizontally arranged On the outer lower side of the spray pipe 3, t...

Abstract

The invention discloses a filter cloth cleaning device of vacuum filter machine and pressurized filter machine without cleaning filter cloth, which comprises the following parts: discharge scraper, spray pipe, sprayer and tool apron, wherein the vertical tool apron bottom is fixed on the fixing board, which connects external side of spray pipe, the discharge scraper connects spray pipe to form an integral, a row of outlet is loaded on the spray pipe between tool apron and filter cloth, which is inclined downwards towards sprayer of filter cloth.

Description

technical field [0001] The invention relates to the technical field of filters, in particular to a filter cloth cleaning device for vacuum filters and pressure filters. Background technique [0002] Vacuum filter and pressure filter are all filtering equipment used for solid-liquid separation of various metal or non-metallic pulp and other fine particle materials. During the filtration process, some fine-grained materials will adhere to the surface of the filter cloth or in the filter holes, and cannot completely fall off when the filter cake is blown back to unload the cake, thereby blocking the filter holes and reducing the filtration efficiency in the next cycle. Therefore, the filter cloth must be cleaned regularly with water to ensure good air permeability of the filter cloth and improve filtration efficiency. [0003] There is a filter cloth cleaning device for a vacuum filter or a pressurized filter that is driven by a hydraulic cylinder. During the flushing process,...
