Abstract
The utility model discloses a high -effect type graphite crucible of polycrystalline silicon ingot furnace, including bottom plate and four curb plates, the bottom plate is positioned bottom in the furnace chamber casing of ingot furnace, the curb plate is positioned top in the furnace chamber casing of ingot furnace, four curb plate end to end formation square tubular, square tubular's bottom opening is arranged in the bottom plate upside, every the outside of curb plate is equipped with the one deck heat preservation. The utility model discloses saved the stopper of stationary side plate with the bottom plate, it is bloated to make graphite crucible contract naturally, avoids damaging, and can prevent effectively when the heating keeps warm that the heat runs off.
Description
Technical field
The utility model relates to a kind of component of polycrystalline silicon ingot or purifying furnace, specifically relates to a kind of polycrystalline silicon ingot or purifying furnace high-performance plumbago crucible.
Background technology
Polycrystalline silicon ingot or purifying furnace mainly comprises quartz crucible, for supporting the plumbago crucible of quartz crucible, well heater, heat-insulation cage and furnace chamber housing, arrange plumbago crucible in furnace chamber housing, quartz crucible is placed in plumbago crucible.In prior art; plumbago crucible, primarily of four side plates of end to end formation square tube shape and base plate composition, conveniently locates four side plates and base plate, usually adopts limited block to be positioned on base plate by four sidewalls; but; plumbago crucible is adding in thermal expansion process, and often meeting is the limited block spalling of fixed side, in addition; in polycrystalline silicon ingot casting process; need to make temperature keep constant within a certain period of time, but plumbago crucible has heat losses in the process, causes the usefulness of ingot furnace lower.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model proposes a kind of polycrystalline silicon ingot or purifying furnace high-performance plumbago crucible, eliminate the limited block of fixed side and base plate, plumbago crucible can be made naturally to collapse, avoid damaging, and effectively can prevent heat losses when heating and thermal insulation.
The technical solution of the utility model is achieved in that
A kind of polycrystalline silicon ingot or purifying furnace high-performance plumbago crucible, comprise base plate and four side plates, described base plate is positioned the furnace chamber housing inner bottom part of described ingot furnace, described side plate is positioned the furnace chamber housing inner top of described ingot furnace, four side plate end to end formation one square tubes, the bottom opening of described square tube is placed on the upside of described base plate, and the outside of each described side plate is provided with one layer of heat preservation layer.
As further improvement of the utility model, the side of each side plate is provided with the some waist type grooves be intervally arranged up and down, opposite side is provided with some connecting holes, when four side plates are end to end, the connecting hole of a side plate is just to the waist type groove of adjacent side plates, and described connecting hole is connected by carbon carbon screw with corresponding waist type groove.
The beneficial effects of the utility model are: the utility model provides a kind of polycrystalline silicon ingot or purifying furnace high-performance plumbago crucible, by the separation design of side plate and base plate, eliminate the limited block of fixed side and base plate, plumbago crucible can be made naturally to collapse, avoid in heat-processed, plumbago crucible expands the limited block spalling of fixed side, and passes through at four side plate arranged outside one layer of heat preservation layers, effectively can prevent heat losses when heating and thermal insulation, improve the usefulness of ingot furnace.Preferably, four side sheet rooms pass through the design of the connection of carbon carbon screw and waist type groove, can alleviate the pressure that the expansion of built-in quartz crucible produces.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
By reference to the accompanying drawings, make the following instructions:
1---base plate 2---side plate
21---waist type groove 22---connecting hole
3---thermal insulation layer 4---carbon carbon screw
Embodiment
For enabling the utility model more become apparent, below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.
As shown in Figure 1, a kind of polycrystalline silicon ingot or purifying furnace high-performance plumbago crucible, comprise base plate 1 and four side plates 2, described base plate is positioned the furnace chamber housing inner bottom part of described ingot furnace, described side plate is positioned the furnace chamber housing inner top of described ingot furnace, four side plate end to end formation one square tubes, the bottom opening of described square tube is placed on the upside of described base plate, and the outside of each described side plate is provided with one layer of heat preservation layer 3.Like this, by the separation design of side plate and base plate, eliminate the limited block of fixed side and base plate, plumbago crucible can be made naturally to collapse, avoid in heat-processed, plumbago crucible expands the limited block spalling of fixed side, and passes through at four side plate arranged outside one layer of heat preservation layers, effectively can prevent heat losses when heating and thermal insulation, improve the usefulness of ingot furnace.
Preferably, the side of each side plate is provided with the some waist type grooves 21 be intervally arranged up and down, opposite side be provided with some connecting holes 22, four side plates end to end time, the connecting hole of a side plate is just to the waist type groove of adjacent side plates, and described connecting hole is connected by carbon carbon screw 4 with corresponding waist type groove.Like this, four side sheet rooms pass through the design of the connection of carbon carbon screw and waist type groove, can alleviate the pressure that the expansion of built-in quartz crucible produces.
To sum up, the utility model provides a kind of polycrystalline silicon ingot or purifying furnace high-performance plumbago crucible, by the separation design of side plate and base plate, eliminate the limited block of fixed side and base plate, plumbago crucible can be made naturally to collapse, avoid in heat-processed, plumbago crucible expands the limited block spalling of fixed side, and by four side plate arranged outside one layer of heat preservation layers, effectively heat losses can be prevented when heating and thermal insulation, improve the usefulness of ingot furnace.Preferably, four side sheet rooms pass through the design of the connection of carbon carbon screw and waist type groove, can alleviate the pressure that the expansion of built-in quartz crucible produces.
Above embodiment is with reference to accompanying drawing, is described in detail to preferred embodiment of the present utility model.Those skilled in the art by carrying out amendment on various forms or change to above-described embodiment, but when not deviating from essence of the present utility model, drops within protection domain of the present utility model.
