Abstract
The utility model discloses a silicon liquid overflow alarm structure of a polycrystalline silicon ingot furnace. The silicon liquid overflow alarm structure comprises a base, a crucible, a graphite guard plate and a bottom heat insulation plate, wherein the crucible is arranged above the base; the graphite guard plate is arranged on the periphery of the crucible above the base; the bottom heat insulation plate is arranged below the base, and multiple guide holes are formed in the periphery of the bottom heat insulation plate; multiple overflow holes are formed in the bottom of the graphite guard plate; the overflow holes correspond to the guide holes in number and position. According to the silicon liquid overflow alarm structure of the polycrystalline silicon ingot furnace, when the silicon liquid (even a little) overflows, the silicon liquid can flow out along the overflow holes and is quickly guided into the guide holes; the silicon liquid contacts with an overflow line at the bottom of the polycrystalline furnace along the guide holes within the first time, fuses the overflow line and triggers an overflow alarm in time so that the workers deal with the situation in time to guarantee the equipment and personnel safety.
Description
Technical field
The utility model relates to a kind of polycrystalline silicon ingot or purifying furnace, relates in particular to a kind of polycrystalline silicon ingot or purifying furnace silicon hydrorrhea stream alarm structure.
Background technology
In recent years, due to low-cost and high efficiency advantage, casting polycrystalline silicon becomes one of topmost photovoltaic material, but the security of polycrystalline silicon ingot casting still will be paid much attention to, kyoto, Japan pottery company, ingot furnace has an accident, cause factory all to stop production, financial loss is serious.
Easily there is serious accident in silicon hydrorrhea stream, easily cause structure deteriorate, the problems such as the consume of silicon material, personnel safety in ingot casting production process, in the process of ingot casting, when temperature reaches 1412 ℃, silicon material starts fusing, if colander will occur in now crucible inefficacy, during colander, silicon liquid flows out, contact with stainless steel furnace bottom, grill thoroughly stainless steel plate, make cold water Quick-gasifying, furnace pressure increases fast, thereby produces explosion hazard.
Therefore, it is an important ring that ingot casting takes safety measures, in existing polycrystalline silicon ingot or purifying furnace silicon liquid when there is colander overflow, need to overflow along graphite backplate crack, when silicon liquid touches overflow line, just touch alarm, this mode needs silicon hydrorrhea to flow out when a lot, just can touch the overflow line of polycrystalline furnace bottom, and then touch overflow and report to the police, have poor with the safe reliability not in time shortcoming of reporting to the police.
Utility model content
The purpose of this utility model is to provide a kind of polycrystalline silicon ingot or purifying furnace silicon hydrorrhea stream alarm structure, it has reports to the police in time and the high feature of security reliability, to solve warning that in prior art, polycrystalline silicon ingot or purifying furnace the exists problem poor with safe reliability not in time.
For reaching this object, the utility model by the following technical solutions:
A kind of polycrystalline silicon ingot or purifying furnace silicon hydrorrhea stream alarm structure, it comprises base, crucible, graphite backplate and heat insulating slab at bottom, described crucible is arranged on base, described graphite backplate is arranged at the periphery of the above crucible of base, described heat insulating slab at bottom is arranged at the below of described base, and the periphery of described heat insulating slab at bottom offers several bullports, wherein, the bottom of described graphite backplate offers several overflow weirs, and the number of described overflow weir is corresponding with described bullport with position.
Especially, described heat insulating slab at bottom is square structure, and its side edge all offers four bullports, and described graphite backplate is provided with four, and the bottom of every graphite backplate all offers four overflow weirs.
Especially, described overflow weir is semicircle, circle, Long Circle, square any.
Especially, described bullport is Long Circle hole.
The beneficial effects of the utility model are, compared with prior art described polycrystalline silicon ingot or purifying furnace silicon hydrorrhea stream alarm structure increases the overflow weir corresponding with the bullport of heat insulating slab at bottom at the bottom position of graphite backplate, when silicon hydrorrhea flows, even during a small amount of overflow of silicon liquid, also can flow out along overflow weir, and guide fast silicon liquid to flow in bullport, along bullport, silicon liquid is contacted within the very first time with the overflow line of polycrystalline furnace bottom, fusing overflow line, triggering in time overflow reports to the police, be convenient to staff and tackle in time, assurance equipment and personal security.
Accompanying drawing explanation
Fig. 1 is the structural representation of the polycrystalline silicon ingot or purifying furnace silicon hydrorrhea stream alarm structure that provides of the utility model embodiment 1.
In figure:
1, base; 2, crucible; 3, graphite backplate; 4, heat insulating slab at bottom; 5, bullport; 6, overflow weir.
Embodiment
Below in conjunction with accompanying drawing and by embodiment, further illustrate the technical solution of the utility model.
Refer to shown in Fig. 1, Fig. 1 is the structural representation of the polycrystalline silicon ingot or purifying furnace silicon hydrorrhea stream alarm structure that provides of the utility model embodiment 1.
In the present embodiment, a kind of polycrystalline silicon ingot or purifying furnace silicon hydrorrhea stream alarm structure comprises base 1, crucible 2, four graphite backplates 3 and heat insulating slab at bottoms 4, described crucible 2 is arranged on base 1, the periphery that described four graphite backplates are arranged at base 1 the above crucible 2 is trapped among crucible 2 middle, described heat insulating slab at bottom 4 is arranged at the below of described base 1, and described heat insulating slab at bottom 4 is square structure, its side edge all offers four oblong bullports 5, coordinates bullport 5 in the bottom of every graphite backplate 3, to offer four semicircular overflow weirs 6.
When silicon hydrorrhea flows, silicon liquid is from the bottom of the interior inflow graphite of crucible 2 backplate 3, even like this during a small amount of overflow of silicon liquid, also can flow out along overflow weir 6, and guide fast silicon liquid to flow in bullport 5, along bullport 5, silicon liquid be contacted within the very first time with the overflow line of polycrystalline furnace bottom, fusing overflow line, trigger in time overflow and report to the police, be convenient to staff and tackle in time, assurance equipment and personal security.
Above embodiment has just set forth ultimate principle of the present utility model and characteristic; the utility model is not limited by above-mentioned example; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various variations and change, and these variations and change all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
