Abstract
The utility model provides a single crystal furnace thermal field batching feeding device, mainly comprising a furnace body; a heat preservation cover board is arranged on the furnace body; a guide shell is connected on the heat preservation cover board, and the guide shell is movably connected with the heat preservation cover board in a matching manner; a lifting gear which moves the guide shell up and down is connected on the guide shell; and the lifting gear can be a guide shell hook which is connected and arranged on the guide shell. The single crystal furnace thermal field batching feeding device has simple structure, and has good using effect; when in batch feeding, the lifting gear lifts the guide shell, and increases the distance between the guide shell and silicon material in the furnace, therefore, about 10 percent of silicon material can be additionally added compared with the existing single crystal furnace; as the silicon material is solid state when being added into the furnace, a plurality of air clearances exist in the furnace due to the stack of the silicon material; and the silicon material is melted after being heated, and when the silicon material is melted into liquid state, the volume is only about half of that of the silicon material when in batch feeding, at this time, the guide shell is descended, and the guide shell is led to be matched with the heat preservation cover board, and then next working procedure can be conducted. The single crystal furnace thermal field batching feeding device increases the batch feeding quantity of each heat, and has the characteristics of increasing the output of production and reducing the production cost.
Description
Technical field
The utility model relates to a kind of charging device, particularly a kind of thermal field of single crystal furnace charging device.
Background technology
Employed graphite thermal field structure substantially is all basic identical in the silicon single crystal vertical pulling stove, there is the defective under yielding poorly in this structure, the reason that causes this phenomenon to produce is that the distance between the interior top that adds the silicon material of lower rim and the stove of guide shell is too little, cause institute to add the silicon material and too much will touch guide shell, influence normal pulling monocrystal.
The utility model content
The purpose of this utility model is to provide a kind of simple in structure for the deficiency that solves above-mentioned technology, can effectively increase the distance between the silicon material in guide shell and the stove, does not influence the thermal field of single crystal furnace charging device of thermal field of single crystal furnace ordinary production again.
In order to achieve the above object, the thermal field of single crystal furnace charging device of the utility model design mainly comprises body of heater, body of heater is provided with the insulation cover plate, be connected with guide shell on the insulation cover plate, guide shell is connected with insulation cover plate clearance fit, is connected with the lifting device that moves up and down guide shell on the guide shell.Described lifting device can be to connect the guide shell suspension hook that is provided with on the guide shell.For convenience being connected of guide shell suspension hook and guide shell, the guide shell suspension hook is connected by the guide shell hook with guide shell, and guide shell is linked up with and is fixed on the guide shell.In order to increase the work-ing life of this equipment, make it adapt to its Working environment, guide shell hook and guide shell suspension hook are made up of high temperature steel.
The resulting thermal field of single crystal furnace charging device of the utility model, simple in structure, but good result of use is arranged, when reinforced, promote guide shell by lifting device, increase the distance between the silicon material in guide shell and the stove, thereby comparable existing single crystal growing furnace is added the silicon material about 10%, because the silicon material is a solid state when adding in the stove, be stacked on and have a lot of spaces in the stove, and when the thawing of heating back silicon material, about half of volume, this is to fall guide shell when only feeding intake when becoming liquid state, guide shell and insulation cover plate are cooperated, can carry out next step operation.This thermal field of single crystal furnace charging device has improved the charging capacity of every heat, has the advantages that also reduced production cost when increasing output.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
The utility model will be further described in conjunction with the accompanying drawings below by embodiment.
Embodiment 1
As shown in Figure 1, the thermal field of single crystal furnace charging device that present embodiment is described mainly comprises body of heater 7, body of heater 7 is provided with insulation cover plate 4, be connected with guide shell 3 on the insulation cover plate 4, guide shell 3 is connected with insulation cover plate 4 clearance fit, is connected with the lifting device that moves up and down guide shell 3 on the guide shell 3.Described lifting device is to connect the guide shell suspension hook 1 that is provided with on the guide shell 3.Guide shell suspension hook 1 and guide shell 3 are connected by guide shell hook 2, and guide shell is linked up with 2 and is fixed on guide shell 3 edges suitable for reading by bolt 6.And guide shell hook 2 and guide shell suspension hook 1 are made up of high temperature steel.
During use, earlier mention guide shell 3 by guide shell suspension hook 1, add the state that silicon material 5 arrives as shown in Figure 1 then, then begin heating, melt when silicon material 5 parts, after the height that silicon material 5 is piled up was reduced to a certain degree, guide shell 3 can slowly descend, it is cooperated with insulation cover plate 4, arrive its rotine positioning.
