A kind of heat blower
Technical field
This utility model relates to firing equipment field, is specifically related to a kind of heat blower.
Background technology
Generality needs the occasion of Hot-blast Heating (more than 100 DEG C high heat), and common mode is that the mode using hot-air blower heats.After hot-air blower energising, aerator is in blow air to heater, and directly by heating wire, the heat produced after heating wire energising carries out heat exchange with the cold air passed through, so that raising by the pathogenic wind-warm of air outlet.
It is noted that air inlet can not block when but hot-air blower uses, air outlet pipe arrangement should long meticulous and bending the most should be not too much, the distinguished and admirable obstruction otherwise can be caused to damage hot-air blower or cause fire.Additionally air intake also needs to cleaning, must not have steam or oil gas, and otherwise the heating wire with energising contacts electric leakage or the danger ignited.
Summary of the invention
The purpose of this utility model is to provide a kind of safety type hot air generator, reduction problem to environmental requirement when solving hot blast safety and heat supply.
To achieve these goals, the technical solution of the utility model is: a kind of safety type hot air generator, including heating copper billet, in it is characterized in that described heating copper billet, electrothermal tube and temp.-sensing wire are set, described heating copper billet also sets up heating air duct, one end of heating air duct arranges air channel import, and the other end of heating air duct arranges ducting outlet.
According to preferred embodiment of the present utility model, described heating copper billet surface configuration has air channel groove, air channel groove arranges air duct cover board, the formation heating air duct between air channel groove and air duct cover board.
According to preferred embodiment of the present utility model, some hollow air channel grooves of described heating copper billet surface configuration, every air channel groove is respectively provided with air channel import and ducting outlet.
According to preferred embodiment of the present utility model, the import of described air channel connects actively wind regime, and ducting outlet picks out air port pipeline.
According to preferred embodiment of the present utility model, described active wind regime is compressed air or blower fan.
According to preferred embodiment of the present utility model, described air outlet pipeline is blow gun or air outlet.
According to preferred embodiment of the present utility model, described electrothermal tube and temp.-sensing wire are all connected with external temperature controller.
This utility model, for increasing safety, uses wind to carry out heat exchange with the mode of thermal source isolation, and heating uses electrothermal tube to heat copper billet, and wind regime passes in copper billet, does not contacts with electrothermal tube.It addition, for improving energy conversion efficiency, improving final conversion temperature, advantage of the present utility model is: use wind and thermal source to isolate, Electrical Safety, source of the gas have the impurity also will not be charged;Use multinomial measure to reach high hot purpose;Compact volume is small and exquisite, compares its thermal conversion process speed faster, improves efficiency;Air-out is concentrated, and little area and exact position can carry out local and heat..

Detailed description of the invention
The utility model will be further described with embodiment below in conjunction with the accompanying drawings.
As it can be seen, a kind of safety type hot air generator, including heating copper billet, electrothermal tube 2 and temp.-sensing wire 1 are set in it is characterized in that described heating copper billet 3, described heating copper billet 3 also sets up heating air duct 4, and one end of heating air duct 4 arranges air channel import 6, and the other end of heating air duct 4 arranges ducting outlet 7.
According to preferred embodiment of the present utility model, described heating copper billet 3 surface configuration has air channel groove, air channel groove arranges air duct cover board 5, the formation heating air duct between air channel groove and air duct cover board.
According to preferred embodiment of the present utility model, some hollow air channel grooves of described heating copper billet 3 surface configuration, every air channel groove is respectively provided with air channel import 6 and ducting outlet 7.
According to preferred embodiment of the present utility model, described electrothermal tube 2 and temp.-sensing wire 1 are all connected with external temperature controller.
As it is shown in figure 1, two electrothermal tubes 2 that heating copper billet 3 employing is arranged in the middle part of heating copper billet heat, heating-up temperature is fed back by temp.-sensing wire 1, and is controlled ensureing temperature stability by external temperature controller.If being provided with air channel, arterial highway 4 on described heating copper billet 3, described air channel 4 is arranged along the vertical direction coiling of electrothermal tube 2, and air channel 4 uses the form directly carving air channel groove at heating copper billet 3, and integral type pipeline increases contact area that is distinguished and admirable and that heat between copper billet 3.And use air duct cover board 5 as shown in Figure 3 to cover, facilitate the processing in air channel 4, and ensure the sealing in air channel 4.
Cold wind enters heat blower from air channel import 6, becomes hot blast due to heat exchange principle, and discharge from ducting outlet 7 behind air channel 4.Air channel import 6 can connect the actively wind regime such as compressed air or blower fan;Ducting outlet 7 picks out air port pipeline such as blow gun, air port or special-shaped blowning installation.
As in figure 2 it is shown, air channel 4 uses hollow runner loop to make full use of all heat-absorbent surfaces;Air channel 4 circuit design pattern is close-packed configuration, in the useful space, pipeline is lengthened.Therefore designing compact conformation, compact, firing rate is faster.
As it is shown on figure 3, air channel 4 uses direct engraving mode in heating copper billet 3, and covered by air duct cover board 5, directly do not contact with charged part electrothermal tube 2.Therefore the source of the gas in air channel 4 has steam or the oil also will not be charged.
If it addition, ducting outlet 7 is blocked, source of the gas can be trapped in air channel 4, and owing to temp.-sensing wire 1 is controlled by external temperature controller with electrothermal tube 2, therefore heating copper billet 3 will not over temperature and heat and cause electrothermal tube 2 to damage.This effect protected to whole device.
Above content is to combine concrete preferred implementation further detailed description of the utility model, it is impossible to assert that this utility model is embodied as being confined to these explanations above-mentioned.For this utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, it is also possible to make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
