A plurality of top heaters are installed at the top end inside the heating chamber. Side heaters are installed on the side of the inner portion of the heating chamber. The top heaters are connected with each other in a triangle mode, and the side heaters are connected with each other in a triangle mode. The top heaters are connected with a first transformer through electric cables, and the side heaters are connected with a second transformer through electric cables. The first transformer and the second transformer are connected with a second control cabinet through electric cables. The second control cabinet is connected with a first control cabinet through an electric wire and a communication bus. According to the automatic control type dual power polycrystalline silicon ingot furnace, during a research and development process variable parameters in an equipment test can be greatly expanded, test parameter points can be expanded, and research and development time can be saved. In a production process, capacity factor matching ratio of a heater can be conveniently changed, finished product rate of silicon ingots can be improved, and energy consumption can be reduced.
Description
Technical field
The utility model relates to a kind of automatic control type dual power supply polycrystalline silicon ingot or purifying furnace.
Background technology
Ingot furnace is the key equipment of photovoltaic industry middle and upper reaches, be mainly used in the large production of solar-grade polysilicon ingot, it adopts advanced polysilicon directional freezing technology, the directed condensation-crystallization of special process will be passed through after the silicon material high-temperature fusion, thereby reach the requirement that manufacture of solar cells is used the polysilicon quality, a kind of long time continuous working that is applicable to, the intelligent large production unit that high precision, high reliability, level of automation are high.Yet there is following several shortcoming in existing ingot furnace:
1, well heater adopts the top side parallel form.Add man-hour at well heater, carry out the power ratio of well heater according to the resistance relation of parallel connection.In case machine, the power ratio of this cover well heater is just fixing, can not change again.
2, well heater in the course of the work because voltage is constant, power ratio is also fixed.So, all generate heat with this fixing proportioning in the whole service process.A lot of heats are unwanted in the long brilliant process of equipment, all can distribute by the water coolant of burner hearth.
Because above shortcoming, so that existing ingot furnace has not only been wasted the energy in process of production, and crystallization effect is undesirable.Therefore, should further improve prior art.
The utility model content
The purpose of this utility model provides a kind of automatic control type dual power supply polycrystalline silicon ingot or purifying furnace, to overcome the deficiency of the above-mentioned aspect of currently available products.
The purpose of this utility model is to be achieved through the following technical solutions:
The described a kind of automatic control type dual power supply polycrystalline silicon ingot or purifying furnace of the utility model embodiment, comprise body of heater and be arranged on the interior heating chamber of body of heater, the heating chamber inner tip is provided with some top heater, mode of connection between the top heater is the trilateral mode of connection, top heater is connected with transformer one by cable, described heating chamber inner side is provided with the side well heater, mode of connection between the side well heater is the trilateral mode of connection, the side well heater is connected with transformer two by cable, described transformer two is connected with transformer and is connected with housing two by cable, housing two is connected with housing one with communication bus by electric wire, is provided with the PLC control piece in the housing one; Be provided with voltmeter and voltage controller in the housing two.
The beneficial effects of the utility model are: the varying parameter in the time of in R﹠D process, can enlarging equipment test greatly, and the expanding test parameter point is saved the research and development time; Can change easily in process of production the power ratio of well heater, improve the silicon ingot yield rate, reduce energy consumption.
Description of drawings
The below is described in further detail the utility model with reference to the accompanying drawings.

Fig. 2 is the connection line figure of the top heater of the described a kind of automatic control type dual power supply polycrystalline silicon ingot or purifying furnace of the utility model embodiment;
Fig. 3 is the connection line figure of the side well heater of the described a kind of automatic control type dual power supply polycrystalline silicon ingot or purifying furnace of the utility model embodiment.
Among the figure:
1, housing one; 2, body of heater; 3, heating chamber; 4, housing two; 5, transformer one; 6, transformer two; 7, top heater; 8, side well heater.
Embodiment
As Figure 1-3, the described a kind of automatic control type dual power supply polycrystalline silicon ingot or purifying furnace of the utility model embodiment, comprise body of heater 2 and be arranged on heating chamber 3 in the body of heater 2, heating chamber 3 inner tip are provided with some top heater 7, mode of connection between the top heater 7 is the trilateral mode of connection, top heater 7 is connected with transformer 1 by cable, described heating chamber 3 inner side are provided with side well heater 8, mode of connection between the side well heater 8 is the trilateral mode of connection, side well heater 8 is connected with transformer 26 by cable, described transformer 26 is connected with transformer and 5 is connected with housing 24 by cable, housing 24 is connected with housing 1 with communication bus by electric wire, is provided with the PLC control piece in the housing 1; Be provided with voltmeter and voltage controller in the housing 24.
During concrete the use, when the melted silicon product, by housing 4 ratio of side well heater 8 and top heater 7 is transferred to the required proportioning of suitable fusing, reaches the purpose of rapid melting.And when long brilliant because need by the vertical long crystalline substance of thermograde, 8 needs of side well heater guarantee the corner in advance long crystalline substance just can.So we can reduce side well heater 8 power by controller 24.Like this, whole ingot casting process has accomplished to save most the purpose of energy consumption.When carrying out the equipment research and development, can simply arrange to change the power ratio of top heater 7 and side well heater 8 by system, be used for detecting the clean effect of polysilicon under the condition of well heater different capacity proportioning, and originally produced the situation that a cover well heater can only be tested a kind of power ratio.And this project can be saved the research and development time expanding test parameter point greatly.Can change easily during the course the power ratio of well heater, improve the silicon ingot yield rate, reduce energy consumption.This can not realize at original well heater following formula.And, can only test by again processing well heater in the past.R﹠D costs like this, have significantly been reduced.
The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but do any variation in its shape or structure; every have identical with a application or akin technical scheme, all drops within the protection domain of the present utility model.
