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

Embodiment 1

[0027] Such as Figure 1-5 As shown, the mining backwash filter includes an outer cylinder 1, one end of the outer cylinder 1 is sealed by the first end cover 2, and the other end is sealed by the second end cover 3, and the outer cylinder 1 is provided with a mesh cylinder 4, and the mesh cylinder One end of 4 is connected with the first end cover 2 through the first net tube end cover 5, and the other end is connected with the second end cover 3 through the second net tube end cover 6, and a filtering device 7 is arranged in the net tube 4 ;

[0028] The filter device 7 is provided with a support frame 71, the support frame 71 includes two rings 72, the two rings 72 are connected by a plurality of cross bars 73 to form a cylindrical frame, the outer surface of the support frame 71 is wound with steel wire 77 forms filter screen 76, forms the gap that can pass through between the adjacent steel wire 77, and the inside of support frame 71 is provided with liner cylinder 74, h...

Embodiment 2

[0032] Such as Figure 1-6 As shown, the difference between this embodiment and Embodiment 1 is that a plurality of grooves 75 are arranged on the cross bar 73, and steel wires 77 are wound in the grooves 75 to form a filter screen 76, and the steel wires 77 are clamped in the grooves 75, without It will slide freely to ensure the filtering accuracy.

Embodiment 3

[0034] Such as Figure 1-6As shown, the difference between the present embodiment and the second embodiment is that the cross section of the groove 75 is an inverted triangle, the cross section of the steel wire 77 is a triangle matching the groove 75, and the edges of the steel wire 77 are clamped in the groove 75. Inside, adjacent steel wires 77 form a gap with a small top and a large bottom. When filtering, the filtrate flows from the small mouth of the gap to the big mouth. The filtering effect is good and it is not easy to block the filter screen 76. The large mouth of the gap flows to the small mouth, the backwashing pressure increases, the backwashing effect is good, and the time is short.

Abstract

The invention belongs to the technical field of filters, relates to a backwash filter and particularly relates to a filter for linearly filtering. The filter provided by the invention has the advantages that the filter is applicable to mines, and a filter screen is good in filtering performance and is convenient to clean. According to technical scheme, the mining backwash filter comprises an outer cylinder, wherein one end of the outer cylinder is sealed through a first end cover, and the other end of the outer cylinder is sealed through a second end cover; a screen cylinder is arranged in the outer cylinder, one end of the screen cylinder is connected with the first end cover through a first screen cylinder end cover, and the other end of the screen cylinder is connected with the second end cover through a second screen cylinder end cover; a filtering device is arranged in the screen cylinder. According to the mining backwash filter, the filter screen of the filtering device is formed by a steel wire through winding, so that the linear filtering is realized, the bearing pressure is high, the filtering effect is good, and the filter is unlikely 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...
