Abstract
The invention relates to a resistance furnace. The resistance furnace comprises an inner furnace tube. The upper part of a furnace shell is provided with a material inlet. A heat insulating layer is arranged in the furnace shell. A heat insulating furnace layer is arranged in the heat insulating layer. A heat insulating lining is made from a fireproofing tile or other fireproofing materials. The inner furnace tube that is as high as the furnace shell is arranged in the center inside the furnace body. The outer wall of the inner furnace tube is provided with a groove. The bottom of the inner furnace tube is connected with an end head. Resistance wires surround the external part of the inner furnace tube. The resistance wires are embedded in the groove. The resistance furnace has the beneficial effects that: by adoption of resistance wires that are distributed at different spacing, the temperatures in different positions of the inner furnace tube, namely the furnace cavity, are controlled accurately; the to-be-heated objects are heated accurately; the gradient in a control zone in the inner furnace tube is close to zero; and the temperature difference of any points in the control zone of the furnace cavity is controlled in a range of plus or minus 1 DEG C, so that the accurately average temperature of the furnace cavity is achieved.
Description
Technical field
The present invention relates to a kind of resistance furnace.
Background technology
At present, the laboratory of each universities and colleges, the laboratory of industrial and mining enterprises are measured at chemical analysis, physics, and in the sintering and fusion of metal, pottery, adopt in a large number that resistance furnace heats, roasting, oven dry, heat treated part.But the temperature that can only make furnace chamber of the resistance furnace that adopts now realizes equilibrium basically, can not accurately control the temperature of furnace chamber each point, can not satisfy the needs that furnace chamber different piece temperature is accurately controlled.
Summary of the invention
The purpose of this invention is to provide a kind of resistance furnace, it can accurately control the temperature of different piece in the furnace chamber.
The objective of the invention is to realize through following technical scheme:
A kind of resistance furnace comprises interior boiler tube, and feeding mouth is offered on furnace shell top; Establish heat-insulation layer in the furnace shell, establish the heat insulation stove layer in the heat-insulation layer, insulation lining is refractory brick or other refractory materials; The interior center of furnace shell is provided with the interior boiler tube with height such as furnace shell grade, has groove on the outer wall of interior boiler tube, and interior boiler tube bottom connects the termination; Interior boiler tube outer most surrounding resistance wire, resistance wire embeds in the groove.
Beneficial effect of the present invention is: adopted the resistance wire of unequal-interval to distribute; Realize in the internal boiler tube being furnace chamber diverse location point accuracy control over temperature; Accurately heat being heated article; The thermal gradient in boiler tube inner control zone levels off to zero in also can making, the temperature difference between the arbitrfary point the furnace chamber control area in is controlled at ± 1 ℃ scope in, the accurate samming of realization furnace chamber.
Description of drawings
According to accompanying drawing the present invention is done further explain below.
Fig. 1 is the structural representation of the described resistance furnace of the embodiment of the invention.
Among the figure:
1, termination; 2, furnace shell; 3, heat-insulation layer; 4, heat insulation stove layer; 5, resistance wire; 6, interior boiler tube; 7, feeding mouth.
The specific embodiment
As shown in Figure 1, a kind of resistance furnace, boiler tube 6 in comprising; Feeding mouth 7 is offered on furnace shell 2 tops, establishes heat-insulation layer 3 in the furnace shell 2, establishes heat insulation stove layer 4 in the heat-insulation layer 3; Insulation lining 4 is refractory brick or other refractory materials, and furnace shell 2 interior centers are provided with the interior boiler tube 6 with furnace shell 2 height such as grade, have groove on the outer wall of interior boiler tube 6; Interior boiler tube 6 bottoms connect termination 1, interior boiler tube outer most surrounding resistance wire 5, and resistance wire 5 embeds in the groove.
First kind of embodiment of the present invention: helical ring five circles are one group, and the distance of every group of group inside spin interannular is 1CM, and the distance between group is 2CM, can establish the spiral ring resistance wire more than 2 groups according to the length difference of interior boiler tube.
Second kind of embodiment of the present invention: helical ring six circles are one group, and the distance of every group of group inside spin ring is 1CM, and the distance between group is 2CM, can establish the spiral ring resistance wire more than 2 groups according to the length difference of interior boiler tube.
The third embodiment of the present invention: helical ring have four the circle be one group, five the circle be one group and six the circle be one group of three kinds of distribution mode.Four circles are one group helical ring, and the distance of group inside spin interannular is 2CM.Five circles are one group helical ring, and the distance of group inside spin interannular is 1CM.Six circles are one group helical ring, and the distance of group inside spin interannular is 1CM.And the distance of respectively organizing between helical ring is 2CM, can establish the spiral ring resistance wire more than 2 groups according to the length difference of interior boiler tube.
The 4th kind of embodiment of the present invention: the distance between helical ring begins progressively to increase from 1CM, is 0.3CM apart from increase between every circle.
