Abstract
The utility model discloses a heating device. The heating device comprises an inner furnace tube; resistance wires are circled outside the inner furnace tube; a heat insulation layer is arranged outside the inner furnace tube; a furnace shell is arranged outside the heat insulation layer; and the distances between the resistance wires circled outside the inner furnace tube are unequal. The heating device can accurately control the temperatures of different parts in a furnace chamber.
Description
Technical field
The utility model relates to a kind of heater.
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 realizes equilibrium substantially now, 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.
The content of utility model
The technical problems to be solved in the utility model provides a kind of resistance furnace, and it can accurately control the temperature of different piece in the furnace chamber.
For solving the problems of the technologies described above, the utility model comprises: interior boiler tube, and the resistance wire of interior boiler tube outer most surrounding, interior boiler tube are outward heat-insulation layers, and heat-insulation layer is outward a furnace shell, and the distance between the resistance wire of interior boiler tube outer most surrounding is unequal.
The unequal resistance wire that is meant of distance between resistance wire is looped around boiler tube external spiral shape ring in the outer formation of interior boiler tube, is the spacing of helical ring between two interior boiler tube external spiral shape rings, and the spacing of at least one helical ring and the spacing of other helical ring are unequal.
The helical ring spacing from small to large, then from big to small, or the helical ring spacing is from big to small, then from small to large; Or the helical ring spacing from small to large; Or the helical ring spacing from big to small.
The unequal resistance wire that is meant of distance between resistance wire is a spiral resistance wire, and at least one pitch and other pitch are unequal in the spiral resistance wire.
The pitch of spiral resistance wire is for from small to large, and then from big to small, or pitch is for from big to small, then from small to large; Or pitch is for from small to large; Or pitch is for from big to small.
Because the utility model has adopted the resistance wire of unequal-interval to distribute, and realizes in the internal boiler tube being furnace chamber diverse location point accuracy control over temperature, accurately heats being heated article, the thermal gradient in boiler tube inner control zone levels off to zero in also can making.Temperature difference between the arbitrfary point in the furnace chamber control area is controlled at ± 1 ℃ scope in, realize the accurate samming of furnace chamber.
Description of drawings
Be described in further detail below in conjunction with accompanying drawing and embodiment of the present utility model:
Fig. 1 is the structural representation of the utility model resistance furnace.
The specific embodiment
As shown in Figure 1, the utility model comprises: furnace shell 2, and feeding mouth 7 is offered on furnace shell top, establish heat-insulation layer 3 in the furnace shell, establish heat insulation furnace lining 4 in the heat-insulation layer, insulation lining is refractory brick or other refractory materials, the center is provided with the interior boiler tube 6 contour with furnace shell in the furnace shell, has groove on the outer wall of interior boiler tube.Interior boiler tube bottom connects termination 1.Interior boiler tube outer most surrounding resistance wire 5, resistance wire embeds in the groove, and the distance between resistance wire is unequal.The lead that connects resistance wire passes furnace shell, is connected with external power source.The unequal resistance wire that is meant of distance between resistance wire is looped around boiler tube external spiral shape ring in the outer formation of interior boiler tube, is the spacing of helical ring between two interior boiler tube external spiral shape rings, and the spacing of at least one helical ring and the spacing of other helical ring are unequal; Or resistance wire is spiral resistance wire, and at least one pitch and other pitch are unequal in the spiral resistance wire.
First kind of embodiment of the present utility model: helical ring five circle is one group, and the distance of every group of group inside spin interannular is 1CM, and the distance between group is 2CM, can establish spiral ring resistance wire more than 2 groups according to the length difference of interior boiler tube.
Second kind of embodiment of the present utility model: helical ring six circle is one group, and the distance of every group of group inside spin ring is 1CM, and the distance between group is 2CM, can establish spiral ring resistance wire more than 2 groups according to the length difference of interior boiler tube.
The third embodiment of the present utility model: 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 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 utility model: the distance between helical ring begins progressively to increase from 1CM, is 0.3CM apart from increase between every circle.
The 5th kind of embodiment of the present utility model: the distance between helical ring begins progressively to reduce from 1CM, and between every circle is 0.05CM apart from decrease, and distance is reduced to till 0.
The 6th kind of embodiment of the present utility model: the pitch of spiral resistance wire begins progressively to increase from 0CM, and the recruitment of each pitch is 0.01CM, is that 2CM stops up to pitch.Progressively reduce pitch again, the decrease of each pitch is 0.01CM, is that 0CM stops up to pitch.
The utility model is connected power supply in when work with resistance wire, because the distribution of resistance wire makes heating object in interior boiler tube, but both each point temperature differences, but also temperature is even, has realized accurate temperature controlling.
