Abstract
The utility model relates to a graphite crucible for a polysilicon ingot furnace, belonging to the polysilicon ingot furnace graphite crucible manufacturing technical field. The utility model mainly comprises a bottom plate (3), a side plate and a side plate (2) which are arranged on the bottom plate (3) and the peripheries of which are provided with fastening screws (4), grooves (5) which are arranged between the periphery of the bottom plate (3) and the bottom parts of the side plate (1) and the side plate (2), etc., wherein, the grooves (5) are arranged at any position on the periphery of the bottom plate (3), and the number of the grooves (5) is arbitrary. The utility model makes the overall design of the graphite crucible more reasonable through arrangement of the grooves between the periphery of the bottom plate and the bottom parts of the side plates; when the graphite crucible generates cracks, overflow silicon liquid can be overflowed in time according to the determined flow direction under the guidance of the grooves, and then an alarm is generated to remind operators to pay attention.
Description
Technical field
The utility model relates to a kind of polycrystalline silicon ingot or purifying furnace black-fead crucible, belongs to the manufacturing technology field of polycrystalline silicon ingot or purifying furnace with graphite crucible.
Background technology
The existing polycrystalline silicon ingot or purifying furnace that uses, its black-fead crucible that is used to support silica crucible all is to be combined by four blocks of side plates and a base plate, when the silicon hydrorrhea taking place, silicon liquid can be mobile arbitrarily everywhere in the past on smooth graphite crucible base plate.Because it is a kind of technology accident that the silicon hydrorrhea goes out, must in time find and take corresponding measure to handle, and the uncertain flow direction of silicon liquid have prolonged the time of fire alarming of accident, very easily causes even more serious consequence.
Summary of the invention
The utility model purpose provides a kind of reasonable in design, and is easy to use, can effectively guide the polycrystalline silicon ingot or purifying furnace black-fead crucible that silicon liquid flows to.
The utility model is the polycrystalline silicon ingot or purifying furnace black-fead crucible, comprises base plate, places base plate all around with the side plate of holding screw, and what it is characterized in that base plate also offers groove all around and between the bottom of side plate.
Groove on the described base plate can be optional position, any amount setting around base plate.
The utility model more becomes rationally the global design of black-fead crucible, when crackle appears in silica crucible by offer groove around base plate and between the bottom of side plate, can be under the guiding of groove, overflow silicon liquid is in time flowed to overflow by appointment, produce and report to the police, remind the operator to note.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present utility model;
Fig. 2 removes structural representation behind part side plate and the holding screw for the utility model;
Fig. 3 is the partial sectional view of the utility model user mode;
Fig. 4 is the structure for amplifying schematic diagram of A part shown in Figure 3.
The specific embodiment
The utility model places base plate 3 all around with the side plate 1,2 of holding screw 4 mainly by base plate 3, is opened in around the base plate 3 and the formations such as groove 5 between the bottom of side plate 1,2, and groove 5 is optional position, any amount setting around base plate 3.
During ordinary production, press shown in the accompanying drawing 3, silica crucible 6 is placed in the utility model and can use.Raw material silicon 7 is heated fusing in silica crucible 6.When crackle appears in silica crucible 6, silicon liquid is inevitable past dirty along the slit between graphite crucible and the silica crucible 6, owing to structural reason, graphite crucible and silica crucible can form a slit in the bottom, thus, and can be along the silicon liquid under the slit flow along the groove on the base plate 35 toward dirty, under the guiding of groove 5, overflow silicon liquid in time flows to overflow by appointment, produces to report to the police, and reminds the operator to note.Arrow points shown in the accompanying drawing 4 represents that silicon hydrorrhea stream flows to.
Claims (1)
1. a polycrystalline silicon ingot or purifying furnace black-fead crucible comprises base plate (3), places base plate (3) all around with side plate (1), (2) of holding screw (4), it is characterized in that base plate (3) around and also offer groove (5) between the bottom of side plate (1), (2).
