Abstract
The invention provides a mining combined gas filter, which can adapt to an underground environment and has low filtration resistance and high filter capacity. The gas filter comprises a gas inlet, a shell, filter layers and a gas outlet, wherein the shell is cylindrical; the gas outlet is formed at one end of the cylindrical shell; and the filter layers comprise a rough filter layer, a medium filter layer and a fine filter layer. The gas filter is characterized in that: the rough filter layer, the medium filter layer and the fine filter layer are sleeved in turn; the fine filter layer is positioned on the innermost layer and is sleeved in an inner cylinder; the outer open end of the inner cylinder is communicated with the gas outlet of the shell; the inner end part of the inner cylinder is a blind end; the shell and the cylinder body of the inner cylinder are provided with through holes; and the through hole on the shell is used as the gas inlet.
Description
Technical field
The present invention relates to a kind of pneumatic filter, more particularly, it relates to the mining combined gas filter of the stackable combination of a kind of filtering layer.
Technical background
Its structure of pneumatic filter of design is seen Fig. 1 in the industry at present, it comprises air inlet 1, shell 2, filtering layer, gas outlet 4, described shell 2 is cylindrical, air inlet 1 and gas outlet 4 are arranged at the two ends of cylindrical case 2 respectively, totally 3 layers of filtering layers, be respectively coarse filtration layer 5, middle filtering layer 6, filter bed of essence 7 and be disposed in order between air inlet 1, gas outlet 4, the circumferential part of filtering layer 5,6,3 and shell 2 inwalls are fitted.Be used for mine like this, air passes through air inlet 1 after filter course 5,6,3 filters 4 discharges from the gas outlet.The shortcoming of this filter is exactly the restriction that filtration yield is subjected to air inlet port size.Summary of the invention
Little at existing filter filtration yield, efficient is low, can not adapt to the shortcoming of subsurface environment, the invention provides mining combined gas filter, it can adapt to subsurface environment, filtration resistance is little, filtration yield is big.
The present invention is achieved by the following technical solutions: it comprises air inlet, shell, filtering layer, the gas outlet, described shell is cylindrical, the gas outlet is arranged at an end of cylindrical case, described filtering layer comprises the coarse filtration layer, middle filtering layer, filter bed of essence, it is characterized in that: described coarse filtration layer, middle filtering layer, filter bed of essence is suit successively, described filter bed of essence is positioned at innermost layer, it is set in inner core, the outside open end of described inner core is communicated with the gas outlet of shell, the medial end of described inner core is a cecum, described shell, the cylindrical shell of inner core is provided with through hole, and the through hole on the described shell is described air inlet.
It is further characterized in that: described coarse filtration layer is woven wire or synthetic fibers silk screen, described in filtering layer be a kind of in sponge, nonwoven, synthetic fibers filter cotton, the paper; Described filter bed of essence is glass fibre filter cotton, glass fibre filter paper, activated carbon filtration cotton or activated carbon filtration cotton paper.
The present invention adopts such scheme, because air inlet is the through hole that is arranged at shell, the area of air inlet can be adjusted like this, overcome the end that its air inlet in the prior art is arranged at casing cylinder, its area is limited by the cylindrical shell external diameter, so air inflow is limited, thereby can have influence on the shortcoming of the filtration yield of whole filter.
Description of drawings
Fig. 1 is the structural representation of existing pneumatic filter;
Fig. 2 is a structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing invention is described further.
See Fig. 2, the present invention includes air inlet 1, shell 2, filtering layer, gas outlet 4, shell 2 is cylindrical, gas outlet 4 is arranged at an end of cylindrical case 2, filtering layer comprises coarse filtration layer 3, middle filtering layer 5, filter bed of essence 6, coarse filtration layer 3, middle filtering layer 5, filter bed of essence 6 be suit successively, filter bed of essence 6 is positioned at innermost layer, be set in inner core 7, the outside open end of inner core 7 is communicated with the gas outlet 4 of shell 2, the medial end 8 of inner core 7 is a cecum, is respectively arranged with through hole 9 on the cylindrical shell of shell 2, inner core 7, and the through hole on the shell 2 is an air inlet 10.Coarse filtration layer 3 is for being woven wire, synthetic fibers silk screen; Middle filtering layer 5 is sponge, nonwoven, synthetic fibers filter cotton, paper; Filter bed of essence 6 is glass fibre filter cotton, glass fibre filter paper, activated carbon filtration cotton, activated carbon filtration cotton paper.
