Among the figure, the 1. intake in panel, 2. panel air intake Chuan Mai tunnel, 3. wind blower fan machine station is divided in the panel, 4. panel mining face, 5. not mining blocks, 6. return aircourse, panel of panel, 7. panel mining boundary line, 8. wind direction, 9. blower fan, 10. special-shaped injector, 11. chamber, 12. blower fan mounting bases.
The specific embodiment
As shown in Figures 1 to 4, the utility model mechanization panel ventilation system comprises between intake 1, air intake Chuan Mai tunnel, panel 2,6, two adjacent air intake Chuan Mai tunnels, panel 2, return aircourse, panel it being not mining blocks 5 of panel mining face 4 and panel; Intake 1, air intake Chuan Mai tunnel, panel 2, return aircourse, panel 6 are interconnected, to constitute the panel of ventilation network.
Both sides correspondence in air intake Chuan Mai tunnel, panel 2 is provided with left chamber 13, right chamber 14, and left chamber 13 and right chamber 14 are together to form an independently chamber 11.The ground level of chamber 11, it is provided with blower fan mounting base 12, and blower fan 9 is fixedly mounted on the blower fan mounting base 12.Be provided with blower fan 9 in left side chamber 13, the right chamber 14, equal bolt is connected with special-shaped injector 10 in the outlet of blower fan 9, the air quantity guiding air intake Chuan Mai tunnel, panel 2 that this abnormity injector 10 produces blower fan.Wind blower fan machine station 3 is divided in the blower fan 9 of left side chamber 13, right chamber 14 and interior setting thereof and special-shaped injector 10 common formation panels.Be provided with several air intake Chuan Mai tunnels, panel 2 in the ventilation system of the utility model mechanization panel, be provided with the panel in each air intake Chuan Mai tunnel, panel 2 and divide wind blower fan machine station 3.
Abnormity injector 10 comprises back guide 16 and preceding guide 15, and special-shaped injector 10 integral body are arranged in the scope of chamber 11, and promptly back guide 16 and preceding guide 15 all are arranged in the scope of chamber 11.The air intake of back guide 16 is connected with the outlet of blower fan 9, be provided with acute angle between preceding guide 15 and the back guide 16, so that behind curved 15 foldings of preceding guide, its front port reaches air intake Chuan Mai tunnel, panel 2, with the wind guiding air intake Chuan Mai tunnel, panel 2 of blower fan 9 generations.And the front port of preceding guide 15 is a rectangular opening, the center line of the end face of this rectangular opening and preceding guide 15 is provided with acute angle, like this, the wind of deriving by special-shaped injector 10 will blow out along the length direction in air intake Chuan Mai tunnel, panel 2, to improve gas flow in the air intake Chuan Mai tunnel, panel 2.
When the blower fan 9 in wind blower fan machine station 3 is divided in the panel normally moves, the special-shaped injector 10 of blower fan outlet is crossed in the wind circulation that blower fan 9 produces, and go out the interruption-forming high velocity air at it, high velocity air becomes the distinguished and admirable power of injection in air intake Chuan Mai tunnel, panel, it is distinguished and admirable just to form injection like this in air intake Chuan Mai tunnel, panel, promptly divide under the effect of wind blower fan machine station 3 injection power in the panel, to enter the fresh distinguished and admirable injection of panel intake in air intake Chuan Mai tunnel, panel 2, the size of injection air quantity is by minute blower fan model at wind blower fan machine station and the structures shape of special-shaped injector, and the structure of dividing the blower fan model at wind blower fan machine station and special-shaped injector is then according to the design required airflow in panel; The air quantity of injection enters the waste gas that is produced in the mining face washing and cleaning operation process of panel again, and the dirty wind behind the washing and cleaning operation face then enters return aircourse, panel 6, finally enters the main return of mine, discharges the face of land.
Because the utility model has connected special-shaped injector in the outlet of blower fan 9, and the blower fan that will connect special-shaped injector is installed in the chamber of tunnel sidewall, what the panel of Gou Chenging divided that wind blower fan machine station 3 not only can be according to the design required airflow like this requires the injection air quantity, and avoided conventional fan machine station to be installed in defective in the tunnel, can be effectively with the scope of operation of fresh distinguished and admirable injection to the panel, reach the action effect at blower fan machine station, do not take drift section, do not influence the transportation of pedestrian and trackless diesel-engine equipment, installation and removal simultaneously are convenient, have bigger flexibility.
The present invention adopts K45-6-№ 11 and K45-6-№ 12 blower fans to constitute a plurality of minutes wind blower fan machine stations, carries out The field in the mechanization panel of certain large-scale copper mine, by the open and close blower fan ventilation effect of this method of ventilation is carried out contrast test repeatedly, result such as table 1.
Table 1 mechanization panel method of ventilation test result
As can be seen from Table 1, before the operation of wind blower fan machine station is divided in the panel, the air quantity in air intake Chuan Mai tunnel, panel distributes uneven, wherein the air quantity in the air intake Chuan Mai tunnel, panel of close return side is big, major part is distinguished and admirable to be to belong to waste, and the air quantity in the air intake Chuan Mai tunnel, panel of close inlet side is little, and the air quantity that enters stope is also little, can not satisfy the smoke evacuation dust discharge needs of production; After wind blower fan machine station operation is divided in the panel, the air quantity basis equalization in each air intake Chuan Mai tunnel, panel, and the air quantity that enters stope can meet the needs of production; Simultaneously, after the panel increased branch wind blower fan machine station, total intake in panel obviously increased, the distinguished and admirable obvious minimizing of the short circuit in panel, and the effective of wind amount rate in panel obviously increases, and very helps the timely discharge of operating area dust, diesel engine vent gas, blasting fume etc.As seen, after the panel was provided with branch wind blower fan machine station, the operating environment in panel had obtained obvious improvement, helped protecting the safety in production of workman's healthy and down-hole.
