Abstract
The utility model relates to an insulating layer structure of a furnace body of a polysilicon crucible sintering furnace, which comprises a furnace wall and an insulating layer structure arranged on the furnace wall and is characterized in that the insulating layer structure comprises a nano insulation board. The insulating layer structure of the furnace body of the polysilicon crucible sintering furnace has the beneficial effects that the nano insulation board is additionally arranged; due to the additionally arranged nano insulation board, the heat preservation effect is good; and on the premise of ensuring the temperature rise of the outer wall of the furnace body constant, the thicknesses of other insulating layers in the insulating structure can be decreased greatly, so that the heat storage of the furnace wall is reduced, the temperature rising and forced air cooling temperature reducing efficiency of the furnace is greatly improved, the production period is shortened, the production efficiency is improved and the energy saving effect is achieved.
Description
Affiliated technical field
The utility model relates to a kind of polysilicon crucible sintering furnace body heat insulation layer structure, relates in particular to a kind of polysilicon crucible sintering furnace body heat insulation layer structure of setting up the nano thermal insulation plate.
Background technology
Under normal conditions, the working temperature of polysilicon crucible sintering oven is 1250 degree.The furnace wall heat insulation layer structure of existing polysilicon crucible sintering oven adopts refractory brick (114 millimeters) and ceramic fiber blanket (260 millimeters of thickness) to constitute mostly, and perhaps diatomite insulating block and alumina-silicate refractory fibre blanket constitute.Furnace wall heat insulation layer structure thickness is bigger, and heat absorption in the heat temperature raising process, quantity of heat storage is big, and it is slow relatively to cause heating up; And in air blast cooling cooling process,, cause cooling slow relatively again because quantity of heat storage is big.
Summary of the invention
The purpose of this utility model is to provide a kind of polysilicon crucible sintering furnace body heat insulation layer structure, set up the nano thermal insulation plate, owing to set up nano thermal insulation plate high insulating effect, guaranteeing under the constant prerequisite of furnace body outer wall temperature rise, other insulation layer thicknesses in the heat insulation layer structure can greatly reduce, thereby solve the problems referred to above that prior art exists.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: polysilicon crucible sintering furnace body heat insulation layer structure, comprise the furnace wall, and be arranged on the heat insulation layer structure on the furnace wall, it is characterized in that described heat insulation layer structure comprises the nano thermal insulation plate.The furnace wall heat insulation layer structure of the polysilicon crucible sintering oven in the present patent application adopts the structure that contains the nano thermal insulation plate, its thickness only is 200mm, reduced 1/3rd of furnace wall heat insulation layer structure general thickness, and heat insulation effect is at all not inferior, can reach the prior art level equally or be higher than the prior art level.Adopted the nano thermal insulation plate just, the reducing of furnace wall general thickness, thus significantly reduced the accumulation of heat of furnace wall self, the intensification of stove and the efficient of air blast cooling cooling are greatly improved.The present existing sintering oven SINTERING PRODUCTION cycle needs about 40 hours usually, and the sintering oven SINTERING PRODUCTION cycle of present patent application only needed about 23 hours, and the production cycle shortens greatly, and therefore, production efficiency and energy-saving effect are significant.
Wherein, the nano thermal insulation plate is the nano hole vacuum heat-insulating shield again, and body skin is pmma material or metallic substance, enclosure interior filling mano-porous material.Mano-porous material is: SiO
2Aerogel microball material admixture quality 15～28%Fe (NO

3Or Ti
2O
3Or CuSO
4Or the Al powder, warming plate vacuum tightness is 20PA.In the synthetic glass housing, insert the exsiccant nano-pore heat insulating materials, sealed after being vacuumized forms.Characteristics such as it is low to have thermal conductivity, in light weight
As the further of technique scheme improved and replenish, the utility model adopts following technical measures: described heat insulation layer structure also comprises refractory brick, ceramic beaverboard, calcium silicate board with microporous, and described nano thermal insulation plate is arranged on outermost layer and contacts with the furnace wall.Wherein, the mode that is provided with outward by body of heater inside can be refractory brick, ceramic beaverboard, calcium silicate board with microporous successively, perhaps can refractory brick, calcium silicate board with microporous, ceramic beaverboard, perhaps any permutation and combination of above-mentioned three.
Described heat insulation layer structure is arranged on the inboard, furnace wall.
The beneficial effect that the utlity model has: set up the nano thermal insulation plate, owing to set up nano thermal insulation plate high insulating effect, guaranteeing under the constant prerequisite of furnace body outer wall temperature rise, other insulation layer thicknesses in the insulation construction can greatly reduce, thereby reduced the accumulation of heat of furnace wall self, the intensification of stove and the efficient of air blast cooling cooling are greatly improved, shortened the production cycle, simultaneously, improved production efficiency, reach energy-saving effect.
Description of drawings
Fig. 1 is a sectional structure synoptic diagram of the present utility model.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: polysilicon crucible sintering furnace body heat insulation layer structure, as shown in Figure 1, it comprises furnace wall 1, heat insulation layer structure on being arranged in the furnace wall 1, heat insulation layer structure also comprises refractory brick 2, ceramic beaverboard 3, the calcium silicate board with microporous 4 that is set gradually outward by body of heater inside, nano thermal insulation plate 5, nano thermal insulation plate 5 are arranged on innermost layer and contact with furnace wall 1.Refractory brick 2, ceramic beaverboard 3, calcium silicate board with microporous 4, nano thermal insulation plate 5 and furnace wall 1 all are bonding mutually by sizing agent.
Under nano thermal insulation plate 5 is arranged on innermost layer and prerequisite that furnace wall 1 contacts, for the arrangement mode of each material layer in the heat insulation layer structure, following distortion can also be arranged: the refractory brick 2, calcium silicate board with microporous 4, ceramic beaverboard 3, the nano thermal insulation plate 5 that set gradually outward by body of heater inside; The perhaps any permutation and combination of other of these four kinds of thermal insulation layers.Owing to only change the thermal insulation layer Rankine-Hugoniot relations, overall structure does not change, and therefore omits the structure iron that above-mentioned distressed structure relates to.
Wherein, refractory brick thickness is that 114 millimeters, ceramic fiber plate thickness are that 40 millimeters, calcium silicate board with microporous thickness are that 40 millimeters, nano thermal insulation plate thickness are 10 millimeters.These data are the data of preferable effect, are the better fit relation as heat-insulating property, economic performance.But, be not limited to above-mentioned data in actual applications.
