Abstract
The utility model relates to an ingot casting furnace group, which comprises ingot casing furnaces and a vacuum, wherein a valve is arranged at an outlet of a reserved port of the vacuum pump; the outlet of the reserved port of the vacuum pump is connected with a manually-operated valve; a outlet of the manually-operated valve is connected with a tee joint through a valve; and two ends of the two joint are connected with the vacuum pump of the ingot casting furnace group through connecting pipes. The ingot casting furnace group disclosed by the utility model solves the problem that a plurality of ingot casting furnace group cannot share one vacuum pump, has the characteristics of high efficiency and energy saving, and is simple in structure and easy to operate.
Description
Technical field
The utility model relates to a kind of ingot furnace group, particularly a kind of ingot furnace group of many shared vacuum pumps of ingot furnace.
Background technology
The silicon chip of polysilicon solar cell is that polycrystalline silicon material forms through ingot casting, slice processing, so ingot furnace is the visual plant in photovoltaic field.In the polycrystalline silicon material ingot casting process, to vacuumize usually in the body of heater and in that to vacuumize the silicon material that injects in the argon shield stove back not oxidized, so vacuum pump is the critical facility of DSS stove.Vacuum pump of present DSS stove configuration.Through long-term practice and analysis, vacuum pump of a DSS stove configuration, there is certain effect surplus in vacuum pump, when many vacuum pump effect surplus summations are too big, the waste that can bring the energy.
The effect of DSS stove when operation vacuum pump: along with vacuumizing, the gas that ingot furnace contains certain heat and impurity is discharged from outside the stove, and vacuum pump plays the impurity got rid of in the silicon material and the effect of heat radiation.
The utility model content
Its purpose of the utility model just is to provide a kind of ingot furnace group, thereby has solved the problem of many shared vacuum pumps of ingot furnace group.Characteristics with efficient height, save energy, and simple in structure, easy to operate.
The technical scheme that realizes above-mentioned purpose and take; Comprise ingot furnace and vacuum pump, the outlet of vacuum pump reserved opening is provided with valve, described vacuum pump reserved opening outlet connection hand movable valve; The manually-operated gate outlet connects threeway through valve, and said threeway two ends connect ingot furnace group vacuum pump through connecting leg.
Compared with prior art the utlity model has following advantage.
Owing to adopted the shared structure design of vacuum pump, thereby solved the problem of many shared vacuum pumps of ingot furnace group.Characteristics with efficient height, save energy, and simple in structure, easy to operate.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done further to detail.
Accompanying drawing is this apparatus structure principle schematic.
Embodiment
This device comprises ingot furnace 8 and vacuum pump 1; The outlet of vacuum pump 1 reserved opening is provided with valve, shown in accompanying drawing, and described vacuum pump reserved opening outlet connection hand movable valve; The manually-operated gate outlet connects threeway 4 through valve 3, and said threeway 4 two ends connect ingot furnace group vacuum pump through connecting leg 2.
Described connecting leg 2 is a flexible pipe.
Described connecting leg 2 one ends are provided with plug 5.
The ingot casting process of ingot furnace is divided into heating, fusing, long crystalline substance, annealing, five stages of cooling.Approximately need 57 hours for 450Kg polycrystalline silicon material ingot casting, and the long brilliant stage needs 25 hours, accounts for 43% of total time; And the long brilliant stage is constant voltage (600mber) state; Temperature variation very little (having only 10-20 ℃), the air inlet switch of vacuum pump are in opens 40% constant position, and the control of giving vent to anger is that it should the stage main task; This moment, air output was very little, and a vacuum pump can satisfy many ingot furnaces during long brilliant stage.When a vacuum pump just can satisfy many ingot casting furnace superintendents crystalline substance stage needs, opening many vacuum pumps will inevitably waste energy.
During ingot furnace work, the corresponding whole unlatchings of vacuum pump.The vacuum pump exhaust capacity is in heating, and the task of fusing, annealing, cooling four-stage is suitable basically, but superfluous in long brilliant its ability of stage.Energy dissipation for fear of this moment; Just install a Y-tube 4 (seeing accompanying drawing) additional on the manual valve reserved opening with every vacuum pump; And the ingot furnace 1 vacuum pump 8 usefulness flexible pipes 2 in each district all are connected together, after the vacuum pump of a certain regional 10 ingot furnaces all is communicated with flexible pipe, manual valve cut out and (prevent when oily when impure in the vacuum pump; Cause that sealing property is bad to be had in the air admission extraction pipe, influence the production quality product).Grow crystalline substance during the stage when it is in, a unlatching wherein vacuum pump just can be satisfied the control requirement of giving vent to anger, and vacuum pump can have days off by turns like this, has not only practiced thrift electric energy but also help the vacuum pump prolongs life.
When many vacuum pumps all are connected together with flexible pipe, need every vacuum pump reserved opening is closed.For this reason, install valve 3 additional, the vacuum pump reserved opening is closed.Install valve 3 additional, can prevent effectively that vacuum pump oil and air from flowing into, realize the blocking-up of vacuum pump reserved opening place oil and air.
After many vacuum pumps all are communicated with flexible pipe; In case during wherein a certain damage; Other unspoiled vacuum pumps can provide service temporarily; Gain time for rushing to repair under not blowing out of the ingot casting state, the silicon ingot in the castingprocesses is not scrapped, obtain many vacuum pumps and all be communicated with the benefit of bringing with flexible pipe.
During work, vacuum pump 1 outlet valve 7 is opened with reserved opening outlet valve 6.
Claims (2)
1. ingot furnace group; Comprise ingot furnace (8) and vacuum pump (1); The outlet of vacuum pump (1) reserved opening is provided with valve, it is characterized in that described vacuum pump (1) reserved opening outlet connection hand movable valve; The manually-operated gate outlet connects threeway (4) through valve (3), and said threeway (4) two ends connect ingot furnace group vacuum pump through connecting leg (2).
2. the described a kind of ingot furnace group of root a tree name claim 1 is characterized in that described connecting leg (2) is a flexible pipe.
