Abstract
The utility model relates to an equipment field which produces single crystal silicon, in particular to a single crystal silicon feeding device. The device includes a melting furnace, a support and a feeding funnel, the support is arranged at an inlet on the upper end of the melting furnace, the feeding funnel is arranged on the support, the feeding funnel is a telescopic funnel. The utility model has the beneficial effects that the telescopic feeding funnel can adjust the feeding quantity according to requirement, the operation is simple and convenient, the production time is shortened, and the work efficiency is increased.
Description
Technical field
The utility model relates to the apparatus field of making silicon single crystal, especially a kind of feeder for monocrystalline silicon.
Background technology
Silicon single crystal is to prepare with vertical pulling method mostly.In this method, the production stage of silicon single crystal ingot is as follows: at a melt in furnace polysilicon; A seed crystal is immersed silicon melt; Lift seed crystal in a kind of mode that enough reaches the desired diameter of crystal ingot; And under that diameter growing single-crystal.Usually the crucible of the usefulness 80Kg that generally once can only feed in raw material, the silicon melt of preparation 80Kg is by the silicon single crystal ingot that silicon melt produced of 80Kg.As required if want to prepare the silicon single crystal ingot that the silicon melt greater than 80Kg produces, such as the silicon melt of 100Kg and 120Kg, in reinforced process, reach 80Kg after because the restriction of smelting furnace and feed hopper just can't continue to feed in raw material again.Brought many troubles to production, the production time is long, and production efficiency is low.
The utility model content
The technical problems to be solved in the utility model is: has now in the silicon single crystal preparation in order to overcome, owing to limited by smelting furnace and feed hopper, and the disposable production problem of feeding in raw material and how much can't regulate and bringing, the utility model provides a kind of feeder for monocrystalline silicon.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of feeder for monocrystalline silicon, have smelting furnace, support and feed hopper, border, ingress, smelting furnace upper end is provided with support, places feed hopper on the support, and described feed hopper is the shrinkability funnel.
Described feed hopper has at least two collapsible branch funnels that nest together, and can regulate reinforced what as required.
Described feed hopper be provided with pulling relatively under the branch funnel move up and imbed lifting mechanism at last minute funnel.
The beneficial effects of the utility model are: reinforced what inotropic feed hopper can regulate as required, and are simple to operation, shortened the production time, improved working efficiency.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of existing feeding device.
Fig. 2 is the structural representation of the utility model feeding device.
Fig. 3 is the reinforced view more for a long time of relative Fig. 2.
Among the figure: 1. smelting furnace, 2. support, 3. feed hopper, 4. minute funnel.
Embodiment
As shown in Figure 1, the support 2 of smelting furnace 1 ' upper end in the feeding device of existing silicon single crystal ' on be placed with feed hopper 3 ', reinforced what described feed hopper 3 ' do not have contractility be not easy to regulate.
As shown in Figure 2, a kind of embodiment of feeder for monocrystalline silicon, have smelting furnace 1, support 2 and feed hopper 3, border, ingress, smelting furnace 1 upper end is provided with support 2, place feed hopper 3 on the support 2, described feed hopper 3 is the shrinkability funnel, and feed hopper 3 has at least two collapsible branch funnels 4 that nest together, feed hopper 3 be provided with pulling relatively under branch funnel 4 move up and imbed lifting mechanism in last minute funnel 4, lifting mechanism does not draw in the drawings.
If it is reinforced among Fig. 2 is 80Kg, then reinforced among Fig. 3 just greater than 80Kg.Reinforced when surpassing 80Kg, under branch funnel 4 move up to imbed and divide in the funnel 4 last, facilitate like this and continue to feed in raw material, easy and simple to handle.
Claims (3)
