Abstract

The invention provides an improved mine combined gas filter, the filter has great filtrating capacity and is washed and maintained conveniently, and filter layers can be selectively used according to situation. The gas filter comprises a gas inlet, a housing, the filter layers and a gas outlet, wherein, the housing is in a cylindrical shape; the gas outlet is arranged on one end of the cylindrical housing; the filter layers comprise a coarse filter layer, a middle filter layer and a fine filter layer which are respectively sheathed on internal cylinders, the internal cylinders and the filter layers thereon are respectively arranged in the housing so as to respectively form a coarse filter, a middle filter and a fine filter; outside open ends of the internal cylinders are communicated with the gas outlet of the housing; a gas outlet of the housing of the coarse filter serves as a gas inlet of the middle filter; a gas outlet of the middle filter serves as a gas inlet of the fine filter; the inside end parts of the internal cylinders are blind ends; the internal cylinder bodies are equipped with through holes; the through hole on the housing of the coarse filter serves as the gas inlet; and the middle filter is positioned between the coarse filter and the fine filter.

Description

Modified is mining combined gas filter

Technical field

The present invention relates to a kind of pneumatic filter, be specially the mining combined gas filter of modified.

Technical background

Its structure of pneumatic filter of design is seen Fig. 1 in the industry at present; It comprises air inlet 4, shell 2, filtering layer, gas outlet 1, and said shell 2 is cylindrical, and air inlet 4 and gas outlet 1 are arranged at the two ends of cylindrical case 2 respectively; Totally 3 layers of filtering layers; Be respectively coarse filtration layer 3, middle filtering layer 6, filter bed of essence 5, coarse filtration layer 3, middle filtering layer 6, filter bed of essence 5 are disposed in order between air inlet 4, gas outlet 1, and the circumferential part of

filtering layer

3,6,5 and shell 2 inwalls are fitted.Be used for mine like this, air passes through air inlet 4 after

filter course

3,6,5 filters 1 discharge from the gas outlet.The shortcoming of this filter is exactly the restriction that filtration yield receives air inlet port size, and causes the cleaning maintenance of filter very inconvenient because shell 2 is an integral body, also can not according to circumstances select different filter course combinations flexibly.

Summary of the invention

Little to existing filter filtration yield, efficient is low, maintenance is cleaned in inconvenience, filter course can not be selected the shortcoming used flexibly; The present invention provides modified mining combined gas filter, and its filtration yield is big, be convenient to clean maintenance, filter course can according to circumstances be selected to use.

Technical scheme of the present invention is such, and it comprises air inlet, shell, filtering layer, gas outlet, and said shell is cylindrical, and the gas outlet is arranged at an end of cylindrical case; Said filtering layer comprises coarse filtration layer, middle filtering layer, filter bed of essence, it is characterized in that: said shell is separated into three independently tube sections vertically, and the demarcation strip between the adjacent cartridges section is provided with intercommunicating pore; Said coarse filtration layer, middle filtering layer, filter bed of essence are set with in three independently on the inner core of tube section; Constitute coarse filter, middle filter, fine filter respectively, the barrel of said inner core is provided with through hole, and the outside open end of said fine filter is communicated with the gas outlet of shell; The gas outlet of said coarse filter shell is the air inlet of middle filter; The gas outlet of filter is the air inlet of fine filter in said, and the medial end of said inner core is a cecum, and the cylindrical shell of said inner core is provided with through hole; Through hole on the shell of described coarse filter is said air inlet, and said middle filter is between coarse filter and fine filter.

It is further characterized in that: said coarse filtration layer is woven wire or synthetic fibers silk screen; Filtering layer is a kind of in sponge, nonwoven, synthetic fibers filter cotton, the paper in said; Said 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 coarse filtration layer shell; The area of air inlet can be adjusted like this, overcomes the end that its air inlet in the prior art is arranged at casing cylinder, and 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; Filter course secondly of the present invention adopts the segmentation assembling, is easy to clean and maintenance.

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 further described.

See Fig. 2, the present invention includes air inlet 3, shell, filtering layer, gas outlet 8, shell is cylindrical, and gas outlet 8 is arranged at an end of cylindrical case; Said filtering layer comprises coarse filtration layer 2, middle filtering layer 5, filter bed of essence 6; Coarse filtration layer 2, middle filtering layer 5, filter bed of essence 6 are set with on

inner core

13,11,9;

Inner core

13,11,9 is placed in respectively in the

shell

1,4,7 together with the filtering layer on it 2,5,6, constitutes coarse filter, middle filter, fine filter respectively, and the outside open end of inner core is communicated with the gas outlet 8 of shell; The gas outlet of coarse filter shell is the air inlet of middle filter; The gas outlet of middle filter is the air inlet of fine filter, and the medial end of

inner core

13,11,9 is a

cecum

14,12,10, and the cylindrical shell of

inner core

13,11,9 is provided with through hole; Through hole on the shell 1 of coarse filter is said air inlet 3, and middle filter is between coarse filter and fine filter.Coarse filtration layer 2 is woven wire or synthetic fibers silk screen; In filtering layer 5 are a kind of in sponge, nonwoven, synthetic fibers filter cotton, the paper; Filter bed of essence 6 is glass fibre filter cotton, glass fibre filter paper, activated carbon filtration cotton or activated carbon filtration cotton paper.

Specifically describe below and utilize the course of work of the present invention: the air that carries harmful substances such as containing dust, oil, iron rust and moisture content; Get into filter coarse filtration layer 2 by air admission hole 3; Because air inlet 3 is for being arranged at the through hole of coarse filter shell; The area of air inlet 3 can be adjusted like this, both can guarantee the amount of air inlet, can guarantee that again filtering layer is not filled bad by gas; Filter out the impurity bigger by coarse filtration layer 2 than mesh; Air after coarse filtration layer 2 filters has got into middle filtering layer 5; Middle filtering layer 5 is made by special cotton, is incited somebody to action part by filtering by the water droplet of filtering, dust, greasy dirt at coarse filtration layer 2, and gas gets into filter bed of essence 6 subsequently; Filter bed of essence 6 is processed by the cotton or the paper of precision, behind three layer filtration, can reach the purpose that effectively purifies air.
