Abstract
The utility model discloses a polysilicon furnace with a silicon solution overflow safety protective device, which is provided with a furnace body. A heat-insulated cage is arranged in the furnace body; a charging crucible is placed on a bearing platform at the bottom of the heat-insulated cage; an upper heater and a lower heater are arranged in the heat-insulated cage which is provided with a peripheral cage body, an upper cover plate and a base plate; an upper heat body is fixed with the upper cover of the heat-insulated cage; a lower heating body is arranged between the bearing platform and the base plate of the heat-insulated cage; a heat door is arranged at the middle part of the base plate of the heat-insulated cage; a cooling plate is arranged below the heat door; and a copper silicon solution overflow receiving device is arranged at the bottom of a furnace body below the cooling plate. Under the condition that silicon solution of the crucible overflows, the silicon solution flows to the silicon solution overflow receiving device along the joint part of the a cage body of the heat-insulated cage and the base plate and the clearance of the heat door; and the solution is rapidly crystallized by the receiving device so as to reduce the loss to be minimum. In addition, the utility model plays a role of two-stage safety protection by a monitoring and controlling device, has reasonable design and simple structure and can effectively avoid the damage of the silicon solution to the furnace body and personal injury.
Description
Technical field
The utility model relates to a kind of production unit that is used to produce the base mateiral of solar level battery, and particularly a kind of tool silicon hydrorrhea goes out the polycrystalline silicon furnace of safety guard.
Background technology
Silicon is the common a kind of chemical element of nature, reaches 25.7% inferior to chlorine.Melting temperature is up to 1414 ℃, and the solar-grade polysilicon purity requirement is not less than 99.99%, and polycrystalline silicon ingot or purifying furnace is a kind of professional remelting device, is the polycrystal silicon ingot of producing big specification used for solar batteries.In process of production owing to relate to the melting environment of high temperature, low pressure, so safeguard protection is particularly important.Can occur in the production technique link that the silicon hydrorrhea goes out when the dissolving of polysilicon, crystallisation process unavoidably or take place because of the phenomenon that silicon liquid spills appears in the crucible reason.How support equipment and personnel safety are vital sport technique segments.Because of existing polycrystalline silicon furnace has many unreliable factors in protection, be difficult to satisfy the safety in production requirement.
The technical problems to be solved in the utility model is at the deficiencies in the prior art, and the tool silicon hydrorrhea that has proposed a kind of support equipment and personnel safety goes out the polycrystalline silicon furnace of safety guard.
The technical problems to be solved in the utility model is achieved through the following technical solutions; a kind of tool silicon hydrorrhea goes out the polycrystalline silicon furnace of safety guard; be provided with body of heater; be provided with Thermal insulation cage in the body of heater; the charging crucible is placed on accepting on the platform of Thermal insulation cage bottom; in Thermal insulation cage, be provided with upper heater and following well heater; cage body around Thermal insulation cage is provided with; loam cake and base plate; the loam cake of last heating member and Thermal insulation cage is fixed; following heating member is arranged between the base plate of accepting platform and Thermal insulation cage; middle part at the base plate of Thermal insulation cage is provided with hot topic, is provided with cooling plate below hot topic, and be characterized in: the bottom of body of heater is provided with silicon liquid overflow receiving device below cooling plate.
The technical problems to be solved in the utility model can also come to realize that further described silicon liquid overflow receiving device is a copper coin by the following technical programs.
The utility model compared with prior art, be provided with silicon liquid overflow receiving device, under the situation that crucible silicon hydrorrhea goes out, silicon liquid flows on the silicon liquid overflow receiving device along the seam crossing of the cage body of Thermal insulation cage and base plate and from popular slit, adaptor adopts copper material, and bearing plate has good heat absorption and conduction of heat because of thermal conductivity is good, make the very fast crystallization of silicon liquid, loss is reduced to lower-most point.Play the two-stage safeguard protection by measuring and control device more in addition; the utility model is reasonable in design; simple in structure; can prevent effectively that silicon liquid from breaking or high temperature flows to the bottom when causing the silicon hydrorrhea to go out at crucible; thereby the accidents caused phenomenon of high temperature silicon liquid scaling loss body of heater and water-cooled tube takes place, and avoids damage and the personal injury of silicon liquid to body of heater.
