Description
Technical field:
The utility model relates to the field of coal mining production, in particular to a ventilation system for coal mining.
The background technology is as follows:
Coal mines are areas where mankind is mining coal resources in coal-rich mining areas, and are generally classified into underground coal mines and open pit coal mines. When the coal seam is far from the earth surface, coal is generally selected to be extracted from underground mining roadways, which is an underground coal mine. When the distance between the coal seam and the ground surface is very short, the earth surface soil layer is generally stripped directly to excavate coal, and the coal is an open pit coal mine.
In the underground coal mining process, stable circulation of internal air is a basis for ensuring life safety of workers, and in underground pits, most ventilation systems are provided with air suction due to the fact that harmful gases are abundant, namely, a mode of pumping the internal gas outwards to enable fresh gas to enter the pits is adopted.
The existing ventilation system is provided with early warning equipment for monitoring data of all aspects of the pits and guaranteeing life safety of workers, but because dust is mined in the pits, a filter screen in a pipeline is often blocked, insufficient suction occurs, the ventilation system is inconvenient to clean, and meanwhile, the suction is reduced, so that air circulation in the pits is seriously influenced, and potential safety hazards are caused.
The utility model comprises the following steps:
The utility model aims to provide a ventilation system for coal mining.
The utility model is implemented by the following technical scheme:
The utility model provides a colliery exploitation ventilation system, including the suction fan, ventilation house steward and fan, the input of suction fan communicates with each other with ventilation house steward's one end fixed connection, fixedly connected with a plurality of ventilation branch pipes on the ventilation house steward, every ventilation branch pipe port is installed the fan respectively, all install V type connecting pipe on every fan, the one end of every V type connecting pipe all with corresponding ventilation branch pipe port fixed connection, every fan all fixed embedding is in V type connecting pipe's one end department, the bottom lateral wall department of every V type connecting pipe all is provided with sealed clearance door, all fixed mounting keeps off the net in the vertical pipeline of every V type connecting pipe.
Preferably, the top of V type connecting pipe has inserted sliding connection's T type pole, and the equal fixedly connected with rubber slab of bottom of every T type pole has all cup jointed reset spring on every T type pole, and the equal fixed mounting in top of every V type connecting pipe has the motor, and the equal fixed mounting of the output of every motor has the cam.
Preferably, a monitor is arranged in the vertical pipeline of the V-shaped connecting pipe, the monitor is arranged above the blocking net, a support is arranged at the top end of the V-shaped connecting pipe, and a motor is arranged on the support.
The utility model has the advantages that: install V type connecting pipe between ventilation branch pipe and fan for the bottom at V type connecting pipe is piled up to the inhaled dust, conveniently clears up through sealed clearance door like this, avoids appearing that the pipeline jam influences the condition of wind-force to appear, is provided with the cam of regularly beating simultaneously, makes the dust that keeps off net department can be regularly cleared up, and the circumstances that the big delay keeps off net is stopped up takes place, is located the last room that keeps off the net with the monitor simultaneously, avoids the dust to cause the influence to the monitor like this.
Description of the drawings:
FIG. 1 is a schematic flow diagram of a system of the present utility model;
fig. 2 is a structural view showing connection of a fan and a ventilation manifold according to the present utility model.
In the figure: the air suction machine 1, the ventilation main pipe 2, the fan 3, the V-shaped connecting pipe 4, the baffle net 5, the rubber plate 6, the T-shaped rod 7, the return spring 8, the motor 9, the cam 10 and the monitor 11.
The specific embodiment is as follows:
As shown in fig. 1 and 2, a ventilation system for coal mining comprises a suction fan 1, a ventilation main pipe 2 and a fan 3, wherein the input end of the suction fan 1 is fixedly connected and communicated with one end of the ventilation main pipe 2, a plurality of ventilation branch pipes are fixedly connected to the ventilation main pipe 2, the fan 3 is respectively installed at each ventilation branch pipe port, each fan 3 is provided with a V-shaped connecting pipe 4, one end of each V-shaped connecting pipe 4 is fixedly connected with a corresponding ventilation branch pipe port, each fan 3 is fixedly embedded at one end of each V-shaped connecting pipe 4, a sealing cleaning door is arranged at the bottom side wall of each V-shaped connecting pipe 4, a baffle net 5 is fixedly installed in a vertical pipeline of each V-shaped connecting pipe 4, after the V-shaped connecting pipes 4 are connected, the fan 3 is installed, so that the suction force is generated by the suction fan 1, and the air in the fan 3 is pulled into the V-shaped connecting pipes 4, thereby forming a complete ventilation system, in order to avoid the pipeline blocking, the setting of the V-shaped connecting pipes 4 can well enable dust to be blocked at the bottom of the vertical pipeline, thus the operation is convenient and the cleaning operation is convenient.
The top of V type connecting pipe 4 has inserted sliding connection's T type pole 7, the equal fixedly connected with rubber slab 6 in bottom of every T type pole 7, reset spring 8 has all been cup jointed on every T type pole 7, the equal fixed mounting in top of every V type connecting pipe 4 has motor 9, the equal fixed mounting of output of every motor 9 has cam 10, utilize the motor 9 of timing start simultaneously (the interval is every half hour start), make cam 10 rotate like this, thereby make T type pole 7 can descend, reset spring 8 plays the reset effect, beat screen 5 like this with rubber slab 6, make the dust that is located on screen 5 can receive vibrations and produce the loss, avoid screen 5 to appear blocking up, cause the problem that the suction descends to appear.
A monitor 11 is arranged in the vertical pipeline of the V-shaped connecting pipe 4, the monitor 11 is arranged above the baffle net 5, a bracket is arranged at the top end of the V-shaped connecting pipe 4, and a motor 9 is arranged on the bracket.
The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the utility model.
