Description
Technical field
It the utility model is related to mining equipment technical field, and in particular to a kind of main fan for mines air door defroster.
Background technology
Coal mine main ventilator is responsible for the important task to delivered downhole fresh air, discharge dust and foul atmosphere, and air door
Open and close control underground air volume and direction.Draft type uses the mine of pull-out type, due to taking out during winter
The underground damp-heat air gone out cold and hot exchange at air door, cause air door interface freeze, cause air door can not normal switch, seriously
When make air door deformation, damage.According to《Safety regulations in coal mine》It is required that：The main ventilation unit of 2 sets of equal abilities must be installed, its
In 1 set do spare, back-up ventilation machine must be able to start in 10min.Air door cannot be normally-open during winter in order to prevent, influences
Wind turbine normally starts, it is necessary to takes air door necessary antifreezing measures.Antifreeze referring now to air door relies primarily on hand inspection dimension
Shield, there are heavy workload, operation is dangerous, the antifreeze factor such as unreliable.
The content of the invention
There are heavy workload, antifreeze dangerous, insecure skill to solve the freezing proof technique of existing air door for the utility model
A kind of art problem, there is provided main fan for mines air door defroster.
In order to solve the above technical problems, technical solution is used by the utility model：A kind of main fan for mines air door
Defroster, including ventilation blower and pipeline heater, the air outlet of the ventilation blower are heated by the first pipeline and duct type
The air inlet connection of device, the air outlet of the pipeline heater connect the second pipeline, and second pipeline heats duct type
The hot wind of device air outlet is sent to the air door in air passage.
The wind of air outlet of ventilator reaches 10 DEG C after pipeline heater heating, when the lowest temperature, still
More than 0 DEG C is positively retained at, the wind by heating is sent to air door by the second pipeline, so as to solve air door ice formation issues.
The utility model has the advantages that compared with prior art：
The utility model effectively improves damper surface temperature using mechanically hot wind is constantly blasted；It is easy to operate, effectively
Labor strength is reduced, improves work efficiency；Effectively reduce time and money loss of the equipment in maintenance and repair；
To air door pools zone efficient drying, the service life of equipment is improved；Enhance the reliability of main fan winter operation；Avoid
Staff's winter deicing forms casualty accident because of accident；By setting a gate valve in conduit entrance, after outaged equipment
Close valve, cut off pipeline in it is distinguished and admirable, effectively reduce the air leak rate of air curtain in air passage.
Brief description of the drawings
Fig. 1 is the utility model air door defroster structure diagram.
Fig. 2 is the front view of pipeline heater.
Fig. 3 is the side view of pipeline heater.
Marked in figure as follows：
1- ventilation blowers, the first pipelines of 2-, 3- pipeline heaters, the second pipelines of 4-, 5- air doors, 6- gate valves, 7- insulating layers
