Solve the method for problem
Multiple field heating furnace for the utility model of solving the scheme 1 that above-mentioned problem proposes; Form a plurality of thermal chambers in the stove through on above-below direction, separating with adiabatic wall; It is characterized in that; This adiabatic wall comprises the supporting member that rides over the furnace wall and is configured in a plurality of heat insulation layers on this supporting member; Each heat insulation layer through all around side by side a plurality of heat-insulating blocks of configuration constitute, the seam between the seam between the heat-insulating block of the adjoining course of each heat insulation layer and the heat-insulating block of adjoining course and the furnace wall disposes with the mode on same vertical line not respectively.
The utility model of the scheme 2 that is the basis with the multiple field heating furnace of scheme 1; It is characterized in that; Make the heat-insulating block between the heat insulation layer of adjacency interconnected on vertical section, and make heat-insulating block and the concavo-convex configuration on vertical section of the seam between the furnace wall between the heat insulation layer of adjacency.
Multiple field heating furnace with scheme 2 is the utility model of base case 3; It is characterized in that; The stove internal protecting wall is made up of insulation brick or refractory brick; And through in the furnace wall inner side plane insulation brick is carried out mortar construct and form the protuberance of this furnace wall, being shaped as of said insulation brick is used to fill up the shape in the space that forms between recess and the furnace wall of adiabatic wall.
The utility model effect
Through on above-below direction, separating in the multiple field heating furnace that firing furnace inside forms a plurality of thermal chambers with adiabatic wall; The adiabatic material that constitutes adiabatic wall has the character of shrinking under the high temperature; But, in the utility model, because this adiabatic wall comprises the supporting member that rides over the furnace wall and is configured in a plurality of heat insulation layers on this supporting member; And in each heat insulation layer; Dispose a plurality of heat-insulating blocks all around side by side, and the seam of heat-insulating block and the tweer of seam and adjoining course between the heat-insulating block of each adjoining course is disposed with the mode on same vertical line not respectively, therefore; Even each heat-insulating block shrinks to make between each heat-insulating block and produces the gap in heat treated, also can avoid being created in the gap that connects adiabatic wall on the above-below direction.Therefore, according to the utility model,, also can effectively suppress the gas flow between upper strata stove and the lower floor's stove even shrink under the high temperature of heat-insulating material in heat treated of formation adiabatic wall.
Description of drawings
Fig. 1 is the stove cross direction amplification profile (half part is arranged) of the multiple field heating furnace of this embodiment.
Fig. 2 is the amplification key diagram of seam portion between heat-insulating block and the furnace wall.
Specific embodiments
Below the preferred embodiment of the utility model is described.
Fig. 1 shows the amplification profile (half part is arranged) of the stove cross direction of the multiple field heating furnace of representing this embodiment.The multiple field heating furnace of this embodiment be a kind of by adiabatic wall 7 on above-below direction with the two-layer roller hearth furnace that separates in the stove and form, body of heater 1 is known tunnel structure, portion disposes the roller 2 that a plurality of conveyances are used with a determining deviation within it.Each roller 2 is the outstanding Si-SiC systems of elevated temperature strength, and drives with certain speed through being arranged on the outer drive unit of stove.Si-SiC is the SiC of the densification of impregnation Si in addition, under 1300 ℃, has 250MN/m
2High strength.In addition, its material has outstanding anti-creep property, non-oxidizability, infrared emission property.
The powder that is burnt till thing is contained in the saggar 3 of ceramic,, to roller 2, and heat-treats at 500-1200 ℃ with the state conveyance of arranging a plurality of saggars 3.
6 upper and lower in stove disposes bar-shaped SiC heater 5 with the mode that on the stove cross direction, connects furnace wall 4 respectively.
Adiabatic wall 7 comprises the supporting member 8 that rides over furnace wall 4 and carries a plurality of heat-insulating blocks 9 on this supporting member 8 continuously with staggered shape.
Heat-insulating block 9 is formed on the left and right directions heat insulation layer (12,13,14,15) of configuration side by side, and in this embodiment, the heat insulation layer 12 of the superiors and undermost heat insulation layer 15 are made up of hard plate material, and intermediate layer 13,14 is made up of the felt material of softness.
The sheet material and the felt material that constitute heat-insulating block 9 all have the character of shrinking under the high temperature; But in the utility model; Heat-insulating block between the heat insulation layer of adjacency 9 is configured to make the shape of its interleaved configuration on vertical section; Therefore, can not be created in above-below direction yet and connect the gap of adiabatic wall, promptly cause the gap of gas flow between upper strata stove and the lower floor's stove even each heat-insulating block 9 shrinks and makes and produce the gap between the heat-insulating block 9 between the heat insulation layer of adjacency in heat treated.The size of heat-insulating block 9 does not have special restriction, but in each layer 12,13,14,15, establishes respectively to constitute piece and have same thickness, establishes that the seaming position of heat-insulating block 9 and furnace wall 4 is positioned at position inequality in the layer of adjacency up and down.
And; As shown in Figure 2; In the utility model; Because the seam between the heat-insulating block between the heat insulation layer of adjacency 9 and the furnace wall 4 is disposed with concavo-convex mode on vertical section, though therefore in heat treated each heat-insulating block shrink the seaming position that makes between heat-insulating block and the furnace wall and produce the gap, can not be created in the gap between the perforation adiabatic wall end and furnace wall on the above-below direction yet.In the utility model,, shrink, also can effectively suppress the gas flow between upper strata stove and the lower floor's stove even constitute the heat-insulating material of adiabatic wall under the high temperature in heat treated through making up above-mentioned effect.
In this embodiment; Furnace wall 4 is made up of insulation brick; And through in the furnace wall inner side plane insulation brick is carried out the protuberance 11 that mortar is constructed and formed furnace wall 4; But the formation method of protuberance 11 does not have special qualification, wherein the shape that is shaped as the space that produces between the recess 10 that is used to fill up adiabatic wall 7 and the furnace wall 4 of insulation brick.
