Description

A kind of resistance furnace
Technical field
The utility model relates to electrical and electronic technology field, particularly relates to a kind of resistance furnace.
Background technology
Resistance furnace take electricity as thermal source, is heat energy, heats in stove to metal by heating by electric energy conversion.Resistance furnace and flame ratio, the thermal efficiency is high, and can reach 50-80 ℅, thermal regulation easily controls, and working condition is good, and converter life is long, be applicable to the heating requiring tighter workpiece, but power consumption costly.By heat transfer type, resistance furnace is divided into radiant type resistance furnace and convection type resistance furnace.Radiant type resistance furnace is based on radiant heat transfer, and convection heat transfer' heat-transfer by convection effect is less; Convection type resistance furnace, based on convection heat transfer' heat-transfer by convection, is commonly referred to air circulation resistance furnace, heats by hot-air, and furnace temperature is many lower than 650 DEG C.By electric heating producing method, resistance furnace is divided into directly heating and indirect two kinds.
Common resistance furnace only has three heating tubes in bottom, and firing rate is comparatively slow, and causes the temperature up and down of furnace inner space to differ, affect the heating effect of workpiece, thermal loss is large simultaneously, adds power consumption, the impurity not easy to clean that resistance furnace is inner after using a period of time simultaneously.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of resistance furnace.
The utility model is achieved through the following technical solutions:
A kind of resistance furnace, comprise resistance furnace support, described resistance furnace pedestal upper end is provided with resistance furnace shell, described resistance furnace shell longitudinal cross-section shape is kidney-shaped, resistance furnace inner casing is provided with inside described resistance furnace shell, thermal insulation layer is provided with between described resistance furnace shell, resistance furnace inner casing, described resistance furnace inner housing inner side is provided with some heating tubes, be provided with heating in the middle part of described resistance furnace inner casing and place plate, under described resistance furnace inner casing, middle side part is provided with cleaning door, is provided with adjusting rod between described cleaning door and resistance furnace support.
As optimal technical scheme of the present utility model, described thermal insulation layer is embedded between resistance furnace shell, resistance furnace inner casing, and thickness is 5mm ~ 15mm.
As optimal technical scheme of the present utility model, be articulated and connected between described cleaning door one end and resistance furnace inner casing.
As optimal technical scheme of the present utility model, described adjusting rod is gas bar or hydraulic stem.
Compared with prior art, the beneficial effects of the utility model are: the utility model structure is simple, reasonable in design, resistance furnace structure of the present utility model makes heating tube can carry out homogeneous heating in all directions direction, and the efficiency of heating surface improves greatly, effectively can reduce the loss of heat at thermal insulation layer simultaneously, reduce power consumption, and resistance furnace in use for some time adjusting rod contraction in length cleaning door is opened, be convenient to the cleaning of impurity, easy to operate.
