Abstract
The utility model discloses an oven structure for hot spraying of a large-sized crucible. The crucible is loaded and unloaded through a folding lower heating plate. By means of the oven structure for the hot spraying of the large-sized crucible, the crucible loading and unloading safety coefficients are greatly improved, the crucible is effectively prevented from latent crack, the workload is lowered, the production efficiency is improved, and the production cost is lowered.
Description
Technical field
The utility model relates to a kind of bake oven device, is specifically related to a kind of for the rotatable oven structure of large size crucible heating.
Background technology
Crystalline silicon is as a kind of material that can utilize solar electrical energy generation, and the epoch in short supply in the renewable energy resources are more and more widely used, and photovoltaic all adopts silicon single crystal in early days, but silicon single crystal cost is higher, production efficiency is low, therefore substitute with polysilicon, its cost of polysilicon is low, production capacity is high, the advantage such as decay low, has higher cost performance and competitive edge, current, photovoltaic field, polycrystalline silicon ingot casting technology has developed into a kind of mainstream technology.
Polycrystalline silicon ingot or purifying furnace is by resistive heating, and the good polysilicon of proportioning is packed in the quartz crucible that is coated with silicon nitride coating, the fusing that heats up, then begin to cool down from bottom, form vertical temperature gradient, utilize the mode of directional freeze to obtain polycrystal silicon ingot.Quartz crucible, as the container of silicon material fusing, can not have magazine disastrously to enter, and crucible directly contacts chemical reaction can occur with silicon liquid, ingot is split in generation, therefore must brush highly purified silicon nitride coating on crucible inwall, hot spraying and roller coating are two kinds of processing methodes of brushing crucible coating layer, and wherein roller coating technical matters is simple, coating is inhomogeneous, time is long, and silicon nitride usage quantity is large, and cost is high, the hot-spraying techniqueies that adopt, carry out hot spraying silicon nitride coating more on crucible rotation baking oven at present.
Increase along with crucible size, the quality of crucible also increases thereupon, and G7 crucible quality is 160kg-200kg at present, when the upper and lower crucible of heating rotary oven because of structure and limited space, needing two people to move up and down crucible operates, while manually moving crucible up and down, easily there is landing phenomenon, cause crucible collision impaired, easily produce hidden splitting, cause occurring in ingot casting process silicon hydrorrhea flow phenomenon, affect the production safety of ingot casting operation, reduce labor productivity, improve production cost.
Therefore, need a kind of new technical scheme to address the above problem.
Utility model content
Utility model object: the problem and shortage existing for above-mentioned prior art, the purpose of this utility model is to provide a kind of oven structure for the spraying of large size crucible heating, effectively improves the safety coefficient that crucible is moved up and down.
Technical scheme: for realizing above-mentioned utility model object, the technical solution adopted in the utility model is a kind of bake oven device for the spraying of large size crucible heating, comprise base for supporting, heating unit and be installed on the transmission mechanism on base for supporting 1, described transmission mechanism is connected with heating unit; Described heating unit comprises downside hot-plate, left side hot-plate, right side hot-plate and upside hot-plate, all lock by locking latches and sides adjacent hot-plate at four side hot-plate two ends, described downside hot-plate comprises the folding hot-plate of middle fixedly hot-plate and two ends, described folding hot-plate is connected with fixing hot-plate by hinge, and is rotated folding around fixing hot-plate.
As the utility model, further optimize, described heating unit also comprises forward and backward fixedly bottom surface hot-plate.
As further optimization of the present utility model, described left side hot-plate and right side hot-plate adopt manual unlocking closing structure.
As further optimization of the present utility model, described upside hot-plate is connected with pneumatic opening unit, and the other end of described pneumatic opening unit is fixed on the hot-plate of front fixedly bottom surface.
As further optimization of the present utility model, in the heated chamber that described downside hot-plate, left side hot-plate, right side hot-plate, upside hot-plate and forward and backward fixedly bottom surface hot-plate form, be provided with 7 independent temperature probes.
As further optimization of the present utility model, the rotary folding angle of described folding hot-plate is 0-180 °
Beneficial effect: the utility model compared with prior art, its advantage is: the utility model is carried crucible up and down by collapsible downside hot-plate, greatly improve the safety coefficient while carrying crucible up and down, effectively prevent that crucible collision from hidden splitting occurring, and reduces workman's workload simultaneously, enhance productivity, reduce production costs, the utility model adopts seven independent temp measuring systems, in whole spraying process, the crucible coating layer that the utility model sprays is even, without sticky pot phenomenon.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of heating unit of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, further illustrate the utility model, should understand these embodiment and only for the utility model is described, be not used in restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present utility model.
As shown in Figure 1, the utility model is used for large size crucible to heat, and comprises base for supporting 1, heating unit 2 and is installed on the transmission mechanism 3 on base for supporting 1, and transmission mechanism 3 is connected with heating unit 2.
As shown in Figure 2; described heating unit 2 comprises forward and backward fixedly bottom surface hot-plate 6, downside hot-plate, left side hot-plate 11, right side hot-plate 7 and upside hot-plate 10; downside hot-plate is divided into three sections and comprises the folding hot-plate 9 of middle fixedly hot-plate 8 and two ends; with hinge 12, connect respectively between the two; left side hot-plate 11 and right side hot-plate 7 adopt manual unlocking closing structure; upside hot-plate 10 is connected with pneumatic opening unit 4; the two ends of described four side heat plates are equipped with locking latches 5, protect crucible safety during for rotary oven.
