Problems solved by technology

[0002] At present, the underground high-pressure emulsion in coal mines needs to be filtered and recycled. Generally, it is filtered by a filter. Due to the harsh environment in the mine, a lot of impurities will accumulate on the filter after a period of use, and these impurities will affect the filtration speed of the filter element. and filtration efficiency, therefore, it is necessary to clean the filter element in time
At present, the filter element needs to be removed and cleaned, which requires the machine to be shut down to replace the filter screen, which affects normal production, and at the same time, the cost is high and the replacement time is long

Abstract

The invention belongs to the technical field of filters, relates to a filter for backflushing, and particularly relates to a linear filter. The filter is suitable for being used under mine, and a filter screen has a good filtering performance, and is convenient to clean. The technical scheme for solving the technical problem is that the linear filter comprises an outer cylinder, wherein one end of the outer cylinder is sealed by a first end cover, and the other end of the outer cylinder is sealed by a second end cover; the outer cylinder is internally provided with a screen cylinder; one end of the screen cylinder is connected with the first end cover by a first screen cylinder end cover, and the other end of the screen cylinder is connected with a second end cover by a second screen cylinder end cover; the screen cylinder is internally provided with a filtering device; the filter screen of the filtering device is formed by winding steel wires so as to form linear filtration; the filter is high in pressure bearing, has a good filtering effect, and is difficult to block.

Description

technical field [0001] The invention belongs to the technical field of filters, and relates to a filter for backwashing, in particular to a linear filter. Background technique [0002] At present, the underground high-pressure emulsion in coal mines needs to be filtered and recycled. Generally, it is filtered by a filter. Due to the harsh environment in the mine, a lot of impurities will accumulate on the filter after a period of use, and these impurities will affect the filtration speed of the filter element. and filtration efficiency, therefore, the filter element needs to be cleaned in time. At present, the filter element needs to be removed and then cleaned, which requires shutdown to replace the filter screen, which affects normal production, and at the same time, the cost is high and the replacement time is long. Contents of the invention [0003] The invention overcomes the deficiencies of the prior art, and the technical problem to be solved is: to provide a filte...
