Abstract
A kind of mixed local ventilation system machine being applied to light section big gun pick dash.Be made up of fairing, housing, anti-explosion motor, impeller, diffuser, valve, three-way air duct and inverted ventilation cylinder etc.; Unit press-in can be realized, extract compound ventilation out, forced ventilation is adopted when driving face normally works, becoming plenum ventilation before blowing out is exhaust ventilation, after blowing out, blowing out a large amount of harmful gases discharges produced, the harmful gas produced is blown out in a checker emptying again, then becomes forced ventilation; Reduce and blow out a large amount of harmful gases of rear generation to the pollution in tunnel.
Description
Technical field
The utility model relates to mixed local ventilation system machine, can realize colliery light section big gun pick tunnel unit compound ventilation.
Background technique
At present, because extraction type local ventilator suction journey is short, cannot extract the harmful gas near driving face out, therefore colliery all adopts press-in wind mode to ventilate for light-gauge big gun pick tunnel.The disadvantage of this draft type is: a large amount of harmful gases produced when blowing out are seriously polluted to tunnel.
Summary of the invention
The purpose of this utility model adopts unit mixed ventilation way in light section big gun pick tunnel, the harmful gas produced when effective eliminating is blown out, improve tunnel environment, overcome existing forced ventilation mode and cannot solve a large amount of harmful gases of generation when blowing out to the pollution in tunnel.
The utility model solves the technological scheme that its technical problem adopts: in cutter big gun hole, haul process, adopt forced ventilation mode, discharge working surface dust, when roasting and boiling as two means of processing crude drugs installs, utilize reversing airway valve, change forced ventilation is exhaust ventilation, after blowing out, extract a large amount of harmful gases of blowing out and producing out, then the harmful gas produced is blown out in a checker emptying, then becomes forced ventilation.
The beneficial effects of the utility model are, being discharged, improving the working environment in big gun pick tunnel by blowing out a large amount of harmful gases of rear generation by air duct.
Accompanying drawing explanation
Fig. 1 is the utility model structural front view;
Fig. 2 is the utility model structure plan view.
Embodiment
The utility model relates to mixed local ventilation system machine, and as shown in Fig. 1 ~ 2, valve (1,10,11,14), three-way air duct (2,9,16), diffuser (8) and cylindrical shell (18) pass through Flange joint.Valve (1,11) is opened, when valve (10,14) is closed, distinguished and admirablely enter air duct (not having picture in figure) through valve (1), three-way air duct (2), fairing (3), impeller (5,6), diffuser (8), three-way air duct (9,16) and flange (12), realize forced ventilation.Valve (1,11) is closed, when valve (10,14) is opened, distinguished and admirablely enter air duct (not having picture in figure) through air duct (not having picture in figure), flange (12), three-way air duct (16), inverted ventilation cylinder (15,13), three-way air duct (2), fairing (3), impeller (5,6), diffuser (8), three-way air duct (9) and flange (11), realize exhaust ventilation.
Claims (1)
1. mixed local ventilation system machine, is made up of valve (1,10,11,14), three-way air duct (2,9,16), fairing (3), motor (4,7), impeller (5,6), diffuser (8), connection air duct flange (12,17), cylindrical shell (18) and inverted ventilation cylinder (13,15) etc.; It is characterized in that: three-way air duct (2,9,16), valve (1,10,11,14) and inverted ventilation cylinder (13,15) and cylindrical shell (18) Flange joint, realize compound ventilation by the switch changing valve.
