Abstract

The utility model provides an improved mining combined gas filter, which has large filtering capacity, is convenient to clean and maintain and can select filtration layers for use according to the situation. The improved mining combined gas filter comprises a gas inlet, a housing, the filtration layers and a gas outlet, wherein the housing is takes a shape of a cylinder, and the gas outlet is arranged at one end of the cylindrical housing; the filtration layers comprise a rough filtration layer, an intermediate filtration layer and a fine filtration layer, the rough filtration layer, the intermediate filtration layer and the fine filtration layer are sheathed on an inner cylinder respectively, the inner cylinder and the filtration layers on the inner cylinder are placed in the housing respectively for constituting a rough filter, an intermediate filter and a fine filter respectively, the open end on the outer side of the inner cylinder is communicated with the gas outlet of the housing, the gas outlet of the housing of the rough filter is the gas inlet of the intermediate filter, the gas outlet of the intermediate filter is the gas inlet of the fine filter, the end part on the inner side of the inner cylinder is the blind end, a through hole is formed on a cylinder body of the inner cylinder, the through hole on the housing of the rough filter is the gas inlet, and the intermediate filter is positioned between the rough filter and the fine filter.

Description

A kind of modified is mining combined gas filter

Technical field

The utility model relates to a kind of pneumatic filter, is specially the mining combined gas filter of a kind 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, described shell 2 is cylindrical, 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 is subjected to 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 at existing filter filtration yield, efficient is low, maintenance is cleaned in inconvenience, filter course can not be selected the shortcoming used flexibly, the utility model provides a kind of 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.

The technical solution of the utility model is such, and it comprises air inlet, shell, filtering layer, gas outlet, and described shell is cylindrical, and 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 shell is separated into three independently tube sections vertically, demarcation strip between the adjacent cartridges section is provided with intercommunicating pore, described coarse filtration layer, middle filtering layer, filter bed of essence is set with in three independently on the inner core of tube section, constitute coarse filter respectively, middle filter, fine filter, the barrel of described inner core is provided with through hole, the outside open end of described fine filter is communicated with the gas outlet of shell, the gas outlet of described coarse filter shell is the air inlet of middle filter, the gas outlet of filter is the air inlet of fine filter in described, the medial end of described inner core is a cecum, the cylindrical shell of described inner core is provided with through hole, through hole on the shell of described coarse filter is described air inlet, and described middle filter is between coarse filter and fine filter.

It is further characterized in that: described 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 described; 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 utility model 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, 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; Secondly the utility model filter course 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 utility model.

The specific embodiment

Below in conjunction with accompanying drawing utility model is further described.

See Fig. 2, the utility model comprises air inlet 3, shell, filtering layer, gas outlet 8, and shell is cylindrical, and gas outlet 8 is arranged at an end of cylindrical case; Described 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 is set with in

inner core

13,11, on 9,

inner core

13,11,9 together with the filtering layer on it 2,5,6 are placed in shell 1 respectively, 4, in 7, constitute coarse filter respectively, middle filter, fine filter, 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,

inner core

13,11,9 medial end is a

cecum

14,12,10,

inner core

13,11,9 cylindrical shell is provided with through hole, through hole on the shell 1 of coarse filter is described 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 utility model: the air that carries harmful substances such as containing dust, oil, iron rust and moisture content, enter 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 again that filtering layer was 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 entered middle filtering layer 5, middle filtering layer 5 is made by special cotton, do not incited somebody to action part by filtering at coarse filtration layer 2 by the water droplet of filtering, dust, greasy dirt, gas enters filter bed of essence 6 subsequently, filter bed of essence 6 is made by the cotton or the paper of precision, can reach the purpose that effectively purifies air behind three layer filtration.
