Abstract
The utility model relates to a ventilator used for a mine excavating working surface and a branch roadway, particularly to a mine intelligent emergency ventilator used for the mine excavating working surface and the branch roadway, wherein a pneumatic motor (6) is mounted in a housing (4); an air inlet pipe (5) and an air exhaust pipe (8) are mounted on the pneumatic motor (6); the air inlet pipe (5) is communicated with an underground air source; an impeller (3) is mounted on a rotating shaft of the pneumatic motor (6); an air collector (1) is mounted at the front end of the impeller (3); and air outlet rectifying blades (12) are arranged on one side of the housing (4). By adopting the mine intelligent emergency ventilator, the mine excavating working surface and the branch roadway can still be normally ventilated even when gas content exceeds the standard or the underground power failure occurs, the noise of the blower is reduced, and the range of the blower is enlarged.
Description
Technical field
The utility model relates to the ventilator that uses in an a kind of mine excavation working surface and the tunnel, is specially a kind of mining intelligent emergency ventilator that is applicable in a mine excavation working surface and the tunnel.
Background technique
" safety regulations in coal mine 2010 " the 138 regulation: when content of gas exceeded standard, electrical equipment must quit work.The ventilator of a mine excavation working surface and a tunnel use is to adopt the rotation of anti-explosion motor impeller mostly at present.When content of gas exceeded standard, has a power failure or have an accident power failure, anti-explosion motor quit work, and a getting working face and a tunnel can't ventilate, and the underground work personnel can't escape, and had therefore caused many irreparable damages.And the most air quantity of existing blower fan is little, range short (range has only about 200 meters), and noise is big.
Summary of the invention
The purpose of this utility model is to provide a kind of mining intelligent emergency ventilator, and it has solved when content of gas and has exceeded standard, and has a power failure or during forced outage, anti-explosion motor quits work, the problem that a working surface and a tunnel can't ventilate.
Goal of the invention of the present utility model is achieved through the following channels: a kind of intelligent emergent blower fan that is used for a mine excavation working surface and a tunnel, pneumatic motor is installed in the shell, suction tude and outlet pipe are housed on the pneumatic motor, wind regime under the suction tude connected well, on the pneumatic motor running shaft impeller is installed, impeller is provided with blade, and the impeller front end is equipped with wind collecting unit, and straightener(stator) blade is housed on the shell.
Further, on the suction tude oil sprayer is installed.
Further, on the outlet pipe baffler is installed.
Further, on the shell silencing apparatus is installed.
Further, it is 65 ° that described blade and wheel hub are installed angle, and the blade radius of arc is 1296 millimeters.
The beneficial effects of the utility model: when content of gas exceeds standard, the down-hole has a power failure, a getting working face and a tunnel still can normally ventilate, and have reduced the noise of blower fan simultaneously, have improved the range of blower fan.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1 is the utility model structural representation;
Among the figure: 1-wind collecting unit, 2-silencing apparatus, 3-impeller, 4-shell, 5-suction tude, 6-pneumatic motor, 7-base, 8-outlet pipe, 9-switch, 10-oil sprayer, 11-baffler, 12-straightener(stator) blade.
Embodiment:
As shown in Figure 1, the utility model mining intelligent emergency ventilator, pneumatic motor 6 is installed in its shell 4, pneumatic motor 6 need not electricity also can proper functioning, solved that content of gas exceeds standard, the down-hole had a power failure when power failure or accident of mine disaster took place, anti-explosion motor quits work, the problem that a getting working face and a tunnel can't ventilate.
In order to reduce noise, oil sprayer 10 has been installed on suction tude 5, baffler 11 is installed on the outlet pipe 8, on shell 4, fix a silencer 2.
During work, the down-hole wind regime drives 6 rotations of pneumatic motor after suction tude 5, and discharge with the baffler on the outlet pipe 8 of pneumatic motor 6 11 back.Pneumatic motor 6 impeller 3 rotations of rotation, the wind that the blade disturbance of high speed rotating is come in by wind collecting unit 1 is along straightener(stator) blade 12 ejaculations of 4 li on shell.
In suction tude 5, oil sprayer 10 has been installed, be used for lubricated pneumatic motor 6, control switch 9 also is installed simultaneously.
It is 65 ° that blade and wheel hub are installed angle, and the blade radius of arc is 1296 millimeters, has effectively improved the blast and the wind speed of blower fan outlet, thereby has improved the range of blower fan.
