Description
Technical Field
The invention relates to the field of coal mine equipment, in particular to a bidirectional ventilator used for a coal mine tunnel.
Background
Coal mines are areas where people mine coal resources in coal-rich mining areas, coal mining needs to be driven into the underground, air in coal mine tunnels is particularly important to be mixed, and the existing ventilator is one-way ventilation, low in ventilation efficiency and incapable of timely and fully circulating air in the coal mine tunnels. For this purpose. A bidirectional ventilator used for a coal mine tunnel is provided.
Disclosure of Invention
In order to solve the existing problems, the invention provides a bidirectional ventilator for a coal mine tunnel, which can solve the problems mentioned in the background technology.
The invention is realized by the following technical scheme:
the utility model provides a two-way ventilation machine that colliery tunnel used, includes the hole of induced drafting and the hole of airing exhaust, the hole of induced drafting is placed side by side with the hole of airing exhaust, and the centre is equipped with the baffle, and the hole of induced drafting inwards inhales the air, and the hole of airing exhaust outwards exhaust the air, install the induced draft fan in the hole of induced drafting, install the fan of airing exhaust in the hole of airing exhaust, induced draft fan and the fan of airing exhaust are connected with a synchromesh gear through belt drive mechanism separately, and are a pair of synchromesh gear meshes, one the output shaft of motor is connected to.
Furthermore, the outside of the synchronizing gear is provided with a synchronizing gear cover, and the synchronizing gear cover and the motor are placed above the air suction hole and the air exhaust hole.
Furthermore, a support is welded below the air suction hole and the air exhaust hole.
Compared with the prior art, the invention has the beneficial effects that: the invention can realize the simultaneous operation of air suction and air exhaust through the air suction holes and the air exhaust holes, so that the air in the coal mine tunnel can be fully circulated, the air exchange efficiency in the coal mine tunnel is improved, the safety of the coal mine work is improved, the air suction fan and the air exhaust fan are driven to work by one motor, the installation space is saved, and the waste of resources is reduced.
Drawings
FIG. 1 is a schematic front view of the present invention;
fig. 2 is a schematic top view of the present invention.
In the figure: 1. a support; 2. an air suction hole; 3. an air suction fan; 4. a belt drive mechanism; 5. a synchronizing gear cover; 6. a synchronizing gear; 7. an air exhaust hole; 8. an exhaust fan; 9. an electric motor.
Detailed Description
The invention is described in further detail below with reference to the following detailed description and accompanying drawings:
as shown in fig. 1-2, a bidirectional ventilator for a coal mine tunnel comprises an air suction hole 2 and an air exhaust hole 7, wherein the air suction hole 2 and the air exhaust hole 7 are arranged side by side, a partition plate is arranged in the middle, an air suction fan 3 is arranged in the air suction hole 2, the air suction hole 2 sucks air inwards, an air exhaust fan 8 is arranged in the air exhaust hole 7, and the air exhaust hole 7 exhausts air outwards; the air suction fan 3 and the air exhaust fan 8 are respectively connected with a synchronous gear 6 through a belt transmission mechanism 4, and the pair of synchronous gears 6 are meshed, so that the air quantity of the air suction hole 2 and the air exhaust hole 7 can be the same; one end of a synchronous gear 6 is connected with an output shaft of a motor 9, the motor 9 drives the synchronous gear 6 to move, a synchronous gear cover 5 is arranged on the outer side of the synchronous gear 6, and the synchronous gear cover 5 and the motor 9 are arranged above the air suction hole 2 and the air exhaust hole 7. The support 1 is welded below the air suction hole 2 and the air exhaust hole 7, and the equipment is placed on the ground through the support 1.
The working principle is as follows: the motor 9 is started to enable the pair of synchronizing gears 6 to rotate, the pair of synchronizing gears 6 are respectively connected with the air suction fan 3 and the air exhaust fan 8 through the belt transmission mechanism 4, so that the air suction fan 3 and the air exhaust fan 8 can rotate reversely and synchronously, the air suction hole 2 sucks outside air into the coal mine tunnel, and the air exhaust hole 7 discharges the air in the coal mine tunnel outwards.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
