When the internal temperature reaches more than 1000 ℃, the thickness of the heat-insulating cotton with the heat conductivity coefficient of about 0.04 needs more than 150 millimeters to ensure that the outer surface of the heating furnace keeps normal temperature, so that the traditional heating furnace has huge appearance volume and is inconvenient to use on some instruments.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a small-size high temperature heating furnace, surface temperature is the safe temperature when making the heating furnace volume small and exquisite.

Realize the utility model discloses the technical solution of purpose does: a small-sized high-temperature heating furnace comprises an outer insulation box, a middle supporting plate, an inner insulation box, a heating pipe temperature measuring instrument, a heating pipe, an air inlet pipe, a T-shaped interface, an airflow temperature measuring meter and an air outlet;

the heating pipe and the heating pipe temperature measuring instrument are arranged in the inner heat insulation box; the air inlet pipe, the T-shaped interface, the airflow thermometer and the air outlet are combined into an airflow pipeline which is arranged in the inner heat insulation box and covered by heat insulation cotton; one end of the airflow thermometer is arranged in the T-shaped interface; the inner heat insulation box is fixed on the middle supporting plate, the middle supporting plate is fixed in the outer heat insulation box, and a heat radiation fan is installed on the outer heat insulation box close to one end of the air inlet pipe.

Compared with the prior art, the utility model, it is showing the advantage and is: (1) the corner part of the space can be flexibly utilized to arrange the heating furnace, so that the limited space is reduced; (2) the material usage amount is reduced, so that the weight of the heating furnace is reduced, and the disassembly and the assembly are easier; (3) because adopt the temperature that the outer insulation can was cooled off to mobile medium between interior insulation can and the outer insulation can, so the temperature of outer insulation can all keep in setting for the temperature range always, and the heating furnace of insulating layer is done to the pure cotton that uses heat preservation, can lead to surface temperature to rise and take place danger because reasons such as heating time is long, apparent air is not circulated, so the utility model discloses it is safer relatively.

The present invention will be described in further detail with reference to the accompanying drawings.
