Abstract
An overhead polysilicon furnace is provided with a furnace body, wherein the furnace body is internally provided with a heat-preservation cage, a material loading crucible is arranged on a bearing table at the bottom of the heat-preservation cage, the heat-preservation cage is internally provided with an upper heater and a lower heater, the top of the furnace body is provided with an upper furnace door, one side of the upper furnace door is fixed with a rotating shaft, the rotating shaft is connected with a lifting device arranged on the side wall of the furnace body, the other side of the upper furnace door is provided with a guide rod, and correspondingly, the side wall of the furnace body is provided with a guide hole matched with the guide rod. An overhead furnace one-arm door structure is adopted, and after being opened, the upper furnace door can be moved away from the furnace mouth by rotating through manual operation or mechanical driving; therefore, the overhead polysilicon furnace has the characteristics of simple structure, easy operation and good safety, is applicable to large-scale production, and fills in the gap in China.
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, particularly a kind of up-set type polycrystalline silicon furnace.
Background technology
The development of modernization industry strengthens the demand to the energy on the one hand, causes energy dilemma; In the use of conventional energy resources, discharge a large amount of carbon dioxides on the other hand, cause global " Greenhouse effect ".The dependence to conventional energy resources, accelerated development renewable energy source are tried hard to break away from by various countries for this reason.As optimal renewable energy source, sun power has inexhaustible characteristics, and utilizes solar electrical energy generation to have advantages such as environmental protection, and needn't consider its safety issue.In energy shortage, China that environmental protection problem is serious day by day, low-cost high-efficiency utilize sun power particularly important.Solar cell is exactly to utilize photovoltaic effect sun power to be converted into a kind of device of electric energy.Since the mid-1970s solar cell commercialization in last century, basic transformation in occupation of dominant position, can not take place at 20 years from now on as basic battery material in crystalline silicon.The casting polycrystalline silicon solar cell has stable efficiency of conversion, and the ratio of performance to price is the highest, the polycrystalline silicon used for solar battery ingot furnace, and domestic all is the import U.S., Germany, the home-made polycrystalline silicon furnace does not still have up-set type all with bottom-open type.
Summary of the invention
The technical problems to be solved in the utility model is at the deficiencies in the prior art, has proposed a kind of reasonable in designly, safe, simple, is suitable for the up-set type polycrystalline silicon furnace of producing big specification solar cell.
The technical problems to be solved in the utility model is achieved through the following technical solutions, a kind of up-set type polycrystalline silicon furnace, 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, be characterized in: the top at body of heater is provided with upper furnace door, one side of upper furnace door and a turning axle are fixed, turning axle is connected with lifting device on being located at sidewall of the furnace body, opposite side at upper furnace door is provided with tail rod, is provided with the pilot hole that cooperates with tail rod accordingly on sidewall of the furnace body.
The technical problems to be solved in the utility model can also come by the following technical programs to realize that further the loam cake of Thermal insulation cage body is fixedlyed connected with upper furnace door that upper heater is contained in the bottom of the loam cake of Thermal insulation cage body.
The utility model compared with prior art, adopt up-set type stove single armed door, a side of upper furnace door and a turning axle are fixed, and turning axle is connected with lifting device on being located at sidewall of the furnace body, realize the keying of upper furnace door by lifting device, after upper furnace door is opened, can upper furnace door be removed from the fire door rotation, have simple in structure by manual or Mechanical Driven, easy to operate, the characteristics that security is good are applicable to scale operation, have filled up domestic blank.
Description of drawings
Fig. 1 is a structure diagram of the present utility model.
Embodiment
A kind of up-set type polycrystalline silicon furnace, be provided with body of heater 2, be provided with Thermal insulation cage 1 in the body of heater 2, charging crucible 9 is placed on accepting on the platform 10 of Thermal insulation cage bottom, is provided with upper heater 3 and following well heater 8 in Thermal insulation cage 1, is provided with upper furnace door 6 at the top of body of heater 2, one side of upper furnace door 6 and a turning axle 11 are fixing, turning axle 11 is connected with lifting device 7 on being located at sidewall of the furnace body, is provided with tail rod 4 at the opposite side of upper furnace door 6, is provided with the pilot hole 5 that cooperates with tail rod 4 accordingly on sidewall of the furnace body.The loam cake of Thermal insulation cage body 1 is fixedlyed connected with upper furnace door 6, and upper heater 3 is contained in the bottom of the loam cake of Thermal insulation cage body.Lifting device 7 can adopt cylinder or feed screw nut's structure.
Embodiment 1, the sidewall of the cylinder body of cylinder and body of heater 2 is fixed, and turning axle 11 is set to one with the piston rod of cylinder, and in upper furnace door 6 uphill process, because the effect of tail rod 4 is arranged, upper furnace door can not rotate; Be raised to the position at upper furnace door 6, after tail rod broke away from pilot hole, fire door was removed fire door by manually just realizing freely rotating at this moment.
Embodiment 2, the cylinder body of turning axle and cylinder is set to one, and piston rod and side wall of furnace are fixed, and establish the inlet and outlet mouth in the end of piston rod, establish the inlet and outlet passage in the piston rod.Outer wall at cylinder body is provided with driving cog or drive splines, is set with power wheel on driving cog or drive splines, realizes the upper furnace door rotation by driven by motor.
