Description
Technical field
The utility model relates to coal mine machinery field, is specifically related to a kind of pit shaft hot-air system.
Background technology
At present in northern cold cold weather, due to the specific weather conditions in the north, must have equipment heater when the colliery in the north is run in the winter time, Here it is is arranged on hot-air system on vertical shaft or inclined shaft.The hot blast that hot-air system on traditional colliery provides due to unit heater can not vertically be blown in pit shaft, have impact on the effect of equipment, have air intake perpendicular cuts hot blast air outlet in pit shaft simultaneously, also the antifreezing effect of pit shaft is affected, thus the temperature in hot wind room is not high, the hot blast temperature that pit shaft delivered to by unit heater is low, and pit shaft is very easily icing when temperature is lower in the winter time, adds potential safety hazard when pit shaft runs in the winter time.
Therefore, produce a kind of structure simply, easy to operate, stability is high, long service life, and maintenance and maintenance pit shaft hot-air system easily, have market prospects widely.
Summary of the invention
For the deficiencies in the prior art, the utility model provides a kind of structure simple, and easy to operate, stability is high, long service life, maintenance and maintenance pit shaft hot-air system easily.
The technical solution of the utility model is achieved in that a kind of pit shaft hot-air system, comprise the unit heater being arranged on pit shaft outer upper, described unit heater and level send hot channel to be connected, level send hot channel to be connected with the vertical hot channel that send, hot channel is vertically sent to be arranged on the side of pit shaft, evenly offer heating outlet vertically sending on hot channel, described heating outlet is at least 7, and seven heating outlets are evenly distributed on and vertically send on hot channel, the outlet of heating outlet is towards wellbore centre position, the described hot channel that vertically send is vertically set on the side of shaft in wall.
The outside of described heating outlet is installed with air-out diffusing opening, and air-out diffusing opening is fixedly mounted on the outside of heating outlet by welding manner.
The inwall of the pit shaft outside described air-out diffusing opening is installed with air-out diffusing opening protect-ing frame structure, air-out diffusing opening protect-ing frame structure is longitudinally arranged on the inwall of pit shaft, and the horizontal direction of air-out diffusing opening protect-ing frame structure is provided with reinforcing rib.
The utility model has following good effect: first, this product structure is simple, easy to operate, comprise the unit heater being arranged on pit shaft outer upper, described unit heater and level send hot channel to be connected, level send hot channel to be connected with the vertical hot channel that send, hot channel is vertically sent to be arranged on the side of pit shaft, evenly offer heating outlet vertically sending on hot channel, described heating outlet is at least 7, and seven heating outlets are evenly distributed on and vertically send on hot channel, the outlet of heating outlet is towards wellbore centre position, the described hot channel that vertically send is vertically set on the side of shaft in wall, in use, unit heater can be utilized to continue fabricate-heat, hot blast send hot channel to flow to through level and vertically send hot channel, then the inner heat supply of pit shaft is directly being deep into through heating outlet, hot blast can be avoided not blow into pit shaft and the pit shaft icing phenomenon caused, secondly, the outside of heating outlet is installed with air-out diffusing opening, air-out diffusing opening is fixedly mounted on the outside of heating outlet by welding manner, hot blast can be dispelled, strengthen the diameter of air outlet, hot blast is dispelled, thus realizes hot blast on a large scale, large area air feed, ensures that pit shaft inner homogeneous obtains the covering of hot blast on a large scale, in addition, the inwall of the pit shaft outside air-out diffusing opening is installed with air-out diffusing opening protect-ing frame structure, air-out diffusing opening protect-ing frame structure is longitudinally arranged on the inwall of pit shaft, the horizontal direction of air-out diffusing opening protect-ing frame structure is provided with reinforcing rib, in use, air-out diffusing opening is effectively played a protective role, simultaneously, air-out diffusing opening protect-ing frame structure also can use as helper, enhances the Practical Performance of product.

Detailed description of the invention
As Fig. 1, shown in 2, a kind of pit shaft hot-air system, comprise the unit heater 1 being arranged on pit shaft 4 outer upper, described unit heater 1 and level send hot channel 2 to be connected, level send hot channel 2 to be connected with the vertical hot channel 3 that send, hot channel 3 is vertically sent to be arranged on the side of pit shaft 4, evenly offer heating outlet 7 vertically sending on hot channel 3, described heating outlet 7 is at least 7, and seven heating outlets 7 are evenly distributed on and vertically send on hot channel 3, the outlet of heating outlet 7 is towards pit shaft 4 center, the described hot channel 3 that vertically send is vertically set on the side of pit shaft 4 inwall.
The outside of described heating outlet 7 is installed with air-out diffusing opening 5, and air-out diffusing opening 5 is fixedly mounted on the outside of heating outlet 7 by welding manner.The inwall of the pit shaft 4 outside described air-out diffusing opening 5 is installed with air-out diffusing opening protect-ing frame structure 6, air-out diffusing opening protect-ing frame structure 6 is longitudinally arranged on the inwall of pit shaft 4, and the horizontal direction of air-out diffusing opening protect-ing frame structure 6 is provided with reinforcing rib 8.
This product in use, in order to ensure that pit shaft 4 inside does not freeze, uninterrupted operation heat supply is continued by unit heater 1, hot blast send hot channel 2 to flow to through level and vertically send hot channel 3, the hot blast of horizontal direction is transformed to vertical direction hot wind supply from the top down, hot blast is discharged through heating outlet 7 vertically sending in hot channel 3, and it is inner to be diffused into pit shaft 4 through air-out diffusing opening 5, serves good heat effect to pit shaft 4 inside.Heating outlet 7 is at least 7, and seven heating outlets 7 are evenly distributed on from top to bottom and vertically send on hot channel 3.Because hot blast wind-force in descending process can reduce, arranging too much heating outlet can disperse monsoon intensity.Further, owing to pit shaft being not easy freeze, bottom is not easy to freeze, so, on the monsoon intensity that goes out not go out monsoon intensity higher than bottom heating outlet, just in time agree with upper wellbore and easily freeze, bottom is not easy the characteristic of freezing, and be easy to use quick, efficiency is high.Air-out diffusing opening protect-ing frame structure 6 can effectively protect air-out diffusing opening 5, and when maintenance and maintenance air-out diffusing opening 5, air-out diffusing opening protect-ing frame structure 6 can use as helper, convenient and swift.
