Abstract
The utility model discloses a kind of coal mine hot air heater, comprise cartridge heater and blower fan, all fixed head is fixedly connected with on the top lateral surface of described cartridge heater He on Basolateral face, the electrical heating net that several are genesis analysis is provided with in described cartridge heater, described blower fan and cartridge heater are fixed by several screw assemblies equally distributed, be provided with wind scooper below described blower fan, described wind scooper is fixedly connected on blower fan lower surface by some connecting rods; By blower fan being arranged on the below of cartridge heater, and blower fan employing is axial flow blower, thus can intake of the present utility model and air output be improved, by the setting of wind scooper, and the upper surface of wind scooper is set to dome shape, thus hot blast can be blown out from the space between wind scooper and blower fan to all directions better, and then improve uniformity and the heating effect of heat radiation.
Description
Technical field
The utility model is specifically related to a kind of coal mine hot air heater, belongs to colliery heating system technical field.
Background technology
At present; winter is when underground work such as coal minings; often air-heater can be adopted to warm oneself; but common air-heater is relatively simple for structure; and often only blow warm braw to a direction, so often cause that the temperature in a direction is higher and temperature on other direction is relatively low, not only the higher meeting of local temperature brings the hidden danger causing fire; and it is uneven to dispel the heat, heating effect is poor.
Summary of the invention
For the problems referred to above, the technical problems to be solved in the utility model is to provide that a kind of structure is simple, practical, heat radiation evenly, heating effect is good, effectively can reduce the coal mine hot air heater that the potential safety hazards such as fire occur.
Coal mine hot air heater of the present utility model, comprise cartridge heater and blower fan, all fixed head is fixedly connected with on the top lateral surface of described cartridge heater He on Basolateral face, the electrical heating net that several are genesis analysis is provided with in described cartridge heater, described blower fan and cartridge heater are fixed by several screw assemblies equally distributed, be provided with wind scooper below described blower fan, described wind scooper is fixedly connected on blower fan lower surface by some connecting rods.
Further, described blower fan is axial flow blower.
Further, described wind scooper is dome shape, and upper surface is provided with the depression of dome shape.
The utility model beneficial effect: a kind of structure of the present utility model is simple, practical, heat radiation evenly, heating effect is good, effectively can reduce the coal mine hot air heater that the potential safety hazards such as fire occur, by blower fan being arranged on the below of cartridge heater, and blower fan employing is axial flow blower, thus can intake of the present utility model and air output be improved, by the setting of wind scooper, and the upper surface of wind scooper is set to dome shape, thus hot blast can be blown out from the space between wind scooper and blower fan to all directions better, and then improve uniformity and the heating effect of heat radiation, heat dissipation uniformity of the present utility model is improve by said structure, thus avoid the accumulation of heat, effectively reduce the appearance of the potential safety hazards such as fire.
Accompanying drawing explanation
For ease of illustrating, the utility model is described in detail by following concrete enforcement and accompanying drawing.
Fig. 1 is main TV structure schematic diagram of the present utility model;
Fig. 2 is sectional structure schematic diagram of the present utility model.
Detailed description of the invention
Coal mine hot air heater as depicted in figs. 1 and 2, comprise cartridge heater 1 and blower fan 2, fixed head 3 is all fixedly connected with on the top lateral surface of described cartridge heater 1 He on Basolateral face, the electrical heating net 8 that several are genesis analysis is provided with in described cartridge heater 1, described blower fan 2 and cartridge heater 1 are fixed by several screw assemblies 4 equally distributed, wind scooper 5 is provided with below described blower fan 2, described wind scooper 5 is fixedly connected on blower fan 2 lower surface by some connecting rods 6, described blower fan 2 is axial flow blower, described wind scooper 5 is dome shape, and upper surface is provided with the depression 7 of dome shape.
Embodiment recited above is only be described preferred embodiment of the present utility model, not limits design of the present utility model and scope.Under the prerequisite not departing from the utility model design concept; the various modification that this area ordinary person makes the technical solution of the utility model and improvement; protection domain of the present utility model all should be dropped into; the technology contents of the utility model request protection, all records in detail in the claims.
