Abstract

The utility model discloses a graphite crucible for a polycrystalline silicon ingot furnace, relating to the technical field of the graphite crucible for the polycrystalline silicon ingot furnace. The graphite crucible for the polycrystalline silicon ingot furnace comprises a bottom plate, four side plates and screws, wherein the bottom ends of the four side plates are also provided with not less than four semicircular holes respectively; the four side plates are fixedly arranged on the bottom plate through the screws; grooves are formed around the bottom plate, and the four edges of the bottom plate are also provided with leaking grooves; the positions of the leaking grooves correspond to those of the semicircular holes; the graphite crucible is characterized in that the grooves are wavelike; wavelike troughs correspond to the semicircular holes in the four side plates respectively; the number of the wavelike troughs of the grooves is equal to the number of the semicircular holes; flow-out grooves are formed in the troughs of the grooves and are connected with the leaking grooves. The graphite crucible has the beneficial effect that silicon liquid can quickly flow out from the graphite crucible after the silicon liquid leaks so as to trigger an alarm device and avoid leakage accidents.

Description

Graphite crucible for polycrystalline silicon ingot production furnaces

Technical field

The utility model relates to graphite crucible for polycrystalline silicon ingot production furnaces technical field.

Background technology

The polycrystalline silicon ingot or purifying furnace of existing use, it is all to be combined by four blocks of side plates and a base plate for supporting the plumbago crucible of quartz crucible, when generation silicon hydrorrhea goes out, silicon liquid can flow arbitrarily on smooth plumbago crucible base plate in the past everywhere.Because silicon hydrorrhea goes out, be a kind of technology accident, must find in time and take corresponding measure to process, and the uncertain flow direction of silicon liquid extended the time of fire alarming of accident, very easily causes even more serious consequence.

Utility model content

The technical problems to be solved in the utility model is to provide a kind of graphite crucible for polycrystalline silicon ingot production furnaces, and when there is the leakage of silicon liquid, silicon liquid can flow out fast from plumbago crucible, thereby sets out warning device, avoids causing leakage accident.

The technical solution adopted in the utility model is to provide a kind of graphite crucible for polycrystalline silicon ingot production furnaces, and it comprises that base plate, four side plates, screw ,Si Gece bottoms also have quantity and are no less than 4 semicircle orifices; Each side plate is fixed by screws on base plate; The Si Ge edge that base plate surrounding has groove, base plate is also provided with water clock groove, and the position of water clock groove position and semicircle orifice is corresponding; It is characterized in that groove is waviness, each corrugated trough is corresponding the semicircle orifice of four side plates respectively; The waviness trough number of groove and semicircle orifice quantity equate; The trough of groove has spout, and spout and water clock groove join.

Further, the groove having on the related base plate of the technical program is waviness, object is after silicon liquid leaks out from polycrystalline silicon ingot or purifying furnace, on graphite base plate, flows, and enters groove, the wavy shaped configuration of groove can converge the silicon liquid of leakage fast, then silicon liquid flows out from the spout of groove waviness trough, the water clock groove of the semicircle orifice of approach side plate, base plate, and silicon liquid is from water clock groove water clock, warning leaky line, causes and reports to the police.The groove the utility model proposes is different from the straight groove of existing base plate, and silicon liquid can flow out faster in groove, has reduced accident and has occurred to the time that causes alarm.

Further, the waviness trough of the groove described in the present embodiment, has spout, and the object of spout is that the waviness lowest part at groove joins, and with after ensuring enough silicon liquid and collecting in groove, then flows out.The difference of the present embodiment and traditional base plate groove is that the waviness trough that first converges to groove at silicon liquid is flowing out by spout, when silicon liquid just can not flow out from spout so off and on.

The beneficial effect that the utility model produces is that graphite crucible for polycrystalline silicon ingot production furnaces is being used, and after there is the leakage of silicon liquid, silicon liquid can flow out fast from plumbago crucible, thereby sets out warning device, avoids causing leakage accident.

Fig. 2 is the frontview of brilliant ingot furnace plumbago crucible side plate of the present utility model;

Fig. 3 is the sectional view of the utility model base plate groove.

In figure, 1 base plate, 11 grooves, 12 spouts, 13 water clock grooves, 2 side plates, 21 semicircle orifices, 3 screws.

Embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

Graphite crucible for polycrystalline silicon ingot production furnaces shown in Fig. 1 embodiment, it comprises that base plate 1, four side plates 2, screw 3, four side 2 bottoms also have quantity and are no less than 4 semicircle orifices 21; Each side plate 2 is fixed on base plate 1 by screw 3; The Si Ge edge that base plate 1 surrounding has groove 11, base plate 1 is also provided with water clock groove 12, and water clock Cao12 position and semicircle orifice 21 position are corresponding; It is characterized in that groove 11 is for waviness, each corrugated trough is corresponding the semicircle orifice 21 of four side plates 2 respectively; The waviness trough number of groove 11 and semicircle orifice quantity equate; The trough of groove has spout 13, and spout 13 joins with water clock groove 12.

Further, the groove 11 having on base plate 1 described in the utility model is waviness, object is after silicon liquid leaks out from polycrystalline silicon ingot or purifying furnace, on graphite base plate, flows, and enters groove 11, the wavy shaped configuration of groove 11 can converge the silicon liquid of leakage fast, then silicon liquid flows out from the spout 13 of groove 11 waviness troughs, the semicircle orifice 21 of approach side plate 2, the water clock groove 12 of base plate 1, and silicon liquid is from water clock groove water clock, warning leaky line, causes and reports to the police.The groove 11 the utility model proposes is different from the straight groove of existing base plate, and silicon liquid can flow out faster in groove, has reduced accident and has occurred to the time that causes alarm.

Further, the waviness trough of the groove 11 described in the present embodiment, has spout 13, and the object of spout 13 is that the waviness lowest part at groove 11 joins, and with after ensuring enough silicon liquid and collecting in groove 11, then flows out.The difference of the present embodiment and traditional base plate groove is that the waviness trough that first converges to groove 11 at silicon liquid is flowing out by spout, when silicon liquid just can not flow out from spout 13 so off and on.

The beneficial effect that the utility model produces be graphite crucible for polycrystalline silicon ingot production furnaces in use, after silicon liquid occurs leaking, silicon liquid can flow out fast from plumbago crucible, thereby sets out warning device, avoids causing leakage accident.
