The specific embodiment
Of the present invention minute wind apparatus, its preferable specific embodiment are branch wind apparatus working state schematic representations shown in Fig. 1 a, Fig. 1 b, Fig. 1 c:
Comprise columniform housing 31 and metallic cylinder 32, metallic cylinder 32 is made up of the steel disc that multi-disc has radian, and metallic cylinder 32 places housing 31, and an end of steel disc and housing 31 1 end margins are hinged, and the other end is a movable end;
Housing 31 is with movable hoop 33, and movable hoop 33 is connected with the movable end of steel disc through metal connecting rod 34, is provided with pneumatic operated valve 35 between housing 31 and the movable hoop 33.
Shown in Fig. 2 a, Fig. 2 b, Fig. 2 c, be branch wind apparatus closed condition sketch map.
Colliery of the present invention fully mechanized workface divides the wind dust falling system, and its preferable specific embodiment is shown in Fig. 3 a, Fig. 3 b:
Comprise the air duct of being located in the digging laneway 4, the rear portion of air duct 4 is provided with blower fan 1, and the front portion of air duct 4 is provided with dedusting fan 2 and above-mentioned branch wind apparatus 3.
The movable end of the steel disc of the metallic cylinder of branch wind apparatus 3 is towards the direction of blower fan 1.
The present invention is based on the thought of " reduce discharging and improve working environment "; Developed a kind of adjustable minute wind apparatus,, utilized adjustable minute wind apparatus that the blower fan wind supply quantity is shunted in conjunction with the fully mechanized workface dedusting fan; Through shunting the expansion of the distinguished and admirable prevention heading end dust that comes out; Thereby the dust in whole driving space is compressed to the very little spatial dimension in termination, and this scope sucks the flow field scope smaller or equal to dedusting fan, and then forms a kind of brand-new face-airing dust pelletizing system.
Carry out detailed description in the face of operating principle of the present invention down:
Dust pelletizing system of the present invention comprises blower fan 1, dedusting fan 2, divides wind apparatus 3 and air duct 4 etc.This system is divided into duty and off working state, dedusting fan 2 and 3 work of branch wind apparatus during duty; 3 work quit work dedusting fan 2 with the branch wind apparatus during off working state.During duty, dedusting fan is opened and is started the pneumatic operated valve that divides on the wind apparatus simultaneously, divides wind apparatus to change metallic cylinder movable end openings of sizes, carries out branch wind air quantity and regulates; During off working state, dedusting fan is closed the pneumatic operated valve that makes on the score wind apparatus and closed, and is distinguished and admirable directly through air duct arrival heading end.
Divide wind apparatus to comprise housing 31, metallic cylinder 32, movable hoop 33, metal connecting rod 34 and pneumatic operated valve 35 etc.Pneumatic operated valve 35 is opened, and moves movable hoop 33, drives the metallic cylinder movable end through metal connecting rod 34 and shrinks, thereby divide the branch air port of wind apparatus to open, and realizes distinguished and admirable shunting; Pneumatic operated valve 35 cuts out, and movable hoop 33 initial position that rebounds, metal connecting rod promote the metallic cylinder movable end and open, and sealing divides a wind apparatus to divide the air port, realizes distinguished and admirable direct ventilation.
During practical implementation, can may further comprise the steps:
For a minute wind dedusting state:
(1) move movable hoop, the metal connecting rod promotes the metallic cylinder movable end and shrinks, and carries out distinguished and admirable shunting;
(2) the anti-heading end that flow back into of dust of shunting distinguished and admirable Driven Diffusion to heading end certain distance cooperates ventilating air together dust to be driven to dedusting fan dedusting scope;
(3) according to heading end dust size, regulate metallic cylinder movable end size, and then change the branch distinguished and admirable size of wind and the flow direction, reach best depositing dust state;
For ventilation state:
When (4) stopping to tunnel, close dedusting fan, interlocking close divides wind apparatus simultaneously, and then does not shunt, and only realizes ventilation function.
(5) along with the propelling of work plane and the reach of dedusting fan, when air duct extends, pull down the branch wind apparatus, reinstall reach one joint air duct position, guarantees to divide wind apparatus and work plane and dedusting fan relative position suitable.
Among this present invention, divide wind apparatus can realize wind adjusting in electrodeless minute; Divide wind apparatus and dedusting fan to form locking; Divide the wind apparatus metallic cylinder to constitute by several arc stalloys; According to the dust size, divide wind distinguished and admirable angle through moving the moving metal connecting rod control of loose collar band; The whole system operation mode both can be that forced blower fan works alone and ventilates, and also can be forced blower fan, dedusting fan and the branch wind apparatus cooperating depositing dust that ventilates, and can obtain dedusting ventilation effect preferably.
The above; Be merely the preferable specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, any technician who is familiar with the present technique field is in the technical scope that the present invention discloses; The variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.
