Abstract
The utility model provides a pit resistance furnace, which can be used for heat treatment. The utility model is characterized in that a furnace body is composed of a furnace casing and a furnace lining, and a furnace lid is arranged on the furnace body; the inside of the furnace has a material basket, an electrothermal element, and a motor-driven fan, wherein, the electrothermal element is arranged at the axle wire of the furnace body, and the periphery of the electrothermal element has a jacket coaxial with the furnace body; the jacket has a plurality of uniformly distributed air holes penetrating through the jacket wall, the upper or the lower end of the jacket is provided with an air cylinder, and the fan is arranged in the cylinder.
Description
The utility model relates to the heat treatment resistance furnace, especially a kind of well formula resistance furnace.
In existing well formula resistance furnace, heating in its body of heater all is to distribute to be installed on the sidewall of the furnace body, and heated workpiece is contained in the inboard that charging basket is built in heating, this structure, the heat of heating institute radiation, a part is given the processed workpiece of burner hearth inboard, another part then radiation is given the furnace wall, the workpiece heating is to begin the ecto-entad heating by charging basket, for the processed workpiece in the charging basket is heated evenly, so adopt fan to force gas stream in the stove to flow, but because heating is positioned at the furnace wall, flowing of gas stream in the stove also can't be fully used to the heat of furnace wall the heating radiation, therefore exist the heat of heating not make full use of, the low and problem that wastes energy of the thermal efficiency.
The purpose of this utility model is exactly at the existing in prior technology problem, and provides a kind of heat energy of heating that makes to make full use of, so can improve the thermal efficiency, saves the well formula resistance furnace technical scheme of the energy.
For clearly demonstrating the technical characterstic of this programme, now by a specific embodiment, and in conjunction with its accompanying drawing, the technical characterictic of this programme is described in detail.
Description of drawings:
Fig. 1 is the structural representation of the utility model embodiment.
By accompanying drawing as can be seen, the well formula resistance furnace of this programme, a body of heater that is made of furnace shell 8 and furnace lining 9 is arranged, the bell 7 that is mated is arranged in the upper end of body of heater, and be useful on charging basket 10, the heating 3 of splendid attire processed workpiece and the fan 6 that drives by motor 11 in the burner hearth.Described heating 3 is conventional electrothermal devices that resistance furnace uses, its installation site then is the place, axis at body of heater, and adopt vertical installation, and the electrode 1 that connects with power supply is stretched out outside the body of heater by the body of heater diapire, periphery at heating 3 has the sheath 4 coaxial with body of heater, to be processed with equally distributed a plurality of wind hole 2 that penetrates jacket wall on this sheath 4, in the upper end or the lower end of sheath 4 air duct 5 be arranged in addition.The described air duct 5 of present embodiment is mounted in the upper end of sheath 4, and described fan 6 is housed in air duct 5, and the drive motors 11 that drives this fan 6 then is to be fixed on the bell 7.Certainly, as if the lower end that air duct 5 is placed sheath 4, dress fans 6 in the air duct 5, the motor 11 of drive fan 6 is fixed on the exterior bottom wall of body of heater, and its effect also is the same.Described air duct 5 will be selected resistant to elevated temperatures metal material for use, and sheath 4 can be used resistant to elevated temperatures metal material, also can select the refractory material processing and fabricating for use.
In this programme, because heating is positioned at the place, axis of body of heater, the sheath that is had the wind hole again surrounds, in being equipped with, the upper end of sheath adorns the air duct of fan in addition, in this structure, the heat that heating produced, take out of by the wind hole on the sheath and the bottom of sheath by force by the air-flow that fan is discharged, and the processed workpiece that is contained in the charging basket is distributed in around the sheath, this has just guaranteed that the heat that heating sends mainly is to be used to heat processed workpiece, improved the utilization rate of heating institute caloric value, so its thermal efficiency is improved and has saved the energy.This shows, the utility model compared with prior art, its effect is conspicuous.
