Abstract
The utility model relates to an important part in a single crystal furnace thermal system structure, and in particular relates to an insulation material of a single crystal furnace thermal field. A solidified carbon felt is used for replacing the original soft carbon felt, and comprises an upper insulation solidified carbon felt, an intermediate insulation solidified carbon felt, a lower insulation solidified carbon felt and a furnace bottom insulation solidified carbon felt. The insulation material is thinner on the basis of achieving the insulation effect of the original soft carbon felt, is convenient in operation, saves space, increases the size of the single crystal furnace configuration thermal field, increases the inventory and utilization rate of a single crystal furnace, and realizes the effect of saving energy.
Description
Technical field
The utility model relates to the thermal field of single crystal furnace in the photovoltaic industry, is that a kind of output is high specifically, the lagging material of energy-saving thermal field of single crystal furnace.
Background technology
The thermal field of single crystal furnace overall structure is divided two portions, the centre is support section, bottom and be insulating sections on every side, support section is done lifting for the quartz crucible that supports charging and is rotatablely moved, insulating sections is used for keeping the heat of well heater and forms suitable temperature field, be beneficial to the generation of monocrystalline, the upper, middle and lower heat-preservation cylinder of thermal field insulating sections and furnace bottom use soft carbon felt material to be incubated.
What generally use in the industry at present is 90 type single crystal growing furnaces, what dispose is 20 inch thermal fields, and when reaching the thermal field heat insulation effect, middle stay-warm case is outer will to wrap up the thick soft carbon felt material of 8-10 layer 10mm, the occupied space of soft carbon felt is just enough or surplus is slightly arranged, as shown in Figure 1.
According to the industry development demand, single crystal growing furnace is progressively to large charging capacity future development, and the charging capacity of the 90 type single crystal growing furnaces in enormous quantities that using at present is 80kg, certainly will cause the huge increase of cost and the waste of the present equipment that is using if change the equipment of large model; If configuration 22 inch thermal fields increase charging capacity in 90 type single crystal growing furnaces, because the increase of thermal field size and charging capacity need to just can reach good heat insulation effect at the thick soft carbon felt material of middle stay-warm case external parcel 10-12 layer 10mm, but 90 type single crystal growing furnace internal diameters are limited, the number of plies of the soft carbon felt of stay-warm case external parcel in when increasing the thermal field size, increasing again, the monocrystalline furnace inner space is inevitable not enough, so how this part makes the transformation of novelty at lagging material, make 90 present type single crystal growing furnaces can dispose 22 inch thermal fields, the charging capacity that namely improves single crystal growing furnace can prolong again the work-ing life of 90 type single crystal growing furnaces.
The utility model content
Technical problem to be solved in the utility model is: by transforming the thermal field of single crystal furnace lagging material, make 90 type single crystal growing furnaces can dispose 22 inch thermal fields, improve charging capacity and the utilization ratio of 90 type single crystal growing furnaces.
The technical scheme that its technical problem that solves the utility model adopts is: substitute original soft carbon felt with solidifying the carbon felt, comprise soft carbon felt that thermal field upper, middle and lower stay-warm case is outer and the soft carbon felt of furnace bottom, the curing carbon felt of same thickness and soft carbon felt, the heat insulation effect that solidifies the carbon felt is well more a lot of than soft carbon felt, can greatly save the space that the stay-warm case heat insulating material for external occupies like this, realize that 90 type single crystal growing furnaces dispose 22 inch thermal fields.
The beneficial effects of the utility model are: in 90 type thermal field of single crystal furnace, by substituting original soft carbon felt with solidifying the carbon felt, make the outer lagging material thickness reduction of thermal field stay-warm case, can dispose 22 inches thermal field when reaching heat insulation effect; The thermal field size has increased in addition, charging capacity is many, the power that expends also must increase, but solidify the increase that the good heat insulation effect of carbon felt can remedy power, although namely 90 type single crystal growing furnaces dispose 22 inch thermal fields, also the same when disposing 20 inch thermal field in watt consumption, namely improved the charging capacity of single crystal growing furnace, prolonged the work-ing life of 90 type single crystal growing furnaces, can well accomplish again energy-conservation.

Embodiment
The curing carbon felt of same thickness and soft carbon felt, the heat insulation effect that solidifies the carbon felt is well more a lot of than soft carbon felt, can greatly save the space that the stay-warm case heat insulating material for external occupies like this.As shown in Figure 2,10 layers of thick soft carbon felt of 10mm are compressed into the middle heat preservation solidification carbon felt (5) that thickness only has 70mm, be installed in outside the stay-warm case (4), middle heat preservation solidification carbon felt (5) internal diameter than in the large 2mm of stay-warm case (4) external diameter, middle like this heat preservation solidification carbon felt (5) is in that reduce can to play when lagging material radially takes up space also will good heat insulation effect than the thick soft carbon felt of 10 layers of 10mm; The outer thick upper heat preservation solidification carbon felt (3) of 56mm of installing of upper stay-warm case (2), the internal diameter of upper heat preservation solidification carbon felt (3) is than the large 2mm of upper stay-warm case (2) external diameter; The thickest lower heat preservation solidification carbon felt (7) is installed in the enough situation of lower stay-warm case (6) external space, the internal diameter of lower heat preservation solidification carbon felt (7) is than the large 2mm of lower stay-warm case (6) external diameter, and the external diameter of lower heat preservation solidification carbon felt (7) is than the little 2mm of single crystal growing furnace internal diameter; Furnace bottom heat preservation solidification carbon felt (8) with condition of equivalent thickness substitutes the original soft carbon felt of furnace bottom, make the furnace bottom better heat preservation, furnace bottom solidifies the external diameter of carbon felt (8) than the little 2mm of single crystal growing furnace internal diameter, upper heat preservation solidification carbon felt (3), middle heat preservation solidification carbon felt (5), lower heat preservation solidification carbon felt (7) all are round tube types, and furnace bottom heat preservation solidification carbon felt (8) is the cake type.By with the soft carbon felt that solidifies carbon felt replacing thermal field of single crystal furnace insulating sections, realize that 90 type single crystal growing furnaces dispose 22 inch thermal fields like this.
