Abstract

The utility model provides a silicon liquid overflow receiving device for polysilicon casting furnace, belonging to the polysilicon casting furnace silicon liquid overflow protection device design and manufacture technical field; the utility model mainly comprises a furnace body(5) with rock wool(6), a silicon liquid overflow receiving container(1) arranged on the rock wool(6) on the bottom of the furnace body(5), a filling layer(2) arranged in the silicon liquid overflow receiving container(1) and a metal blown fuse(3) provided with a controller(4), etc.; the utility model can effectively avoid the phenomenon that when the silicon liquid overflows because of the cracked crucible receiving the silicon liquid or other causes, the silicon liquid flowing to the bottom part of the furnace body is accumulated on the bottom part of the furnace body, the high temperature silicon liquid can burn through the steel plate of furnace body, and the cooling water is exposed in the furnace with high temperature and low pressure, causing disastrous accidents.

Description

The silicon liquid overflow receiving device of polycrystalline silicon ingot or purifying furnace

Technical field

The utility model relates to a kind of silicon liquid overflow receiving device of polycrystalline silicon ingot or purifying furnace, belongs to the design and fabrication technology field of polycrystalline silicon ingot or purifying furnace with silicon hydrorrhea stream protective device.

Background technology

Existing polycrystalline silicon ingot or purifying furnace, when silicon hydrorrhea stream takes place when, the high temperature silicon liquid that overflows can arbitrarily trickle on the high temperature resistant rock wool that is laid on bottom of furnace body, when overflowing the silicon liquid measure very for a long time, silicon liquid accumulates in bottom of furnace body on the one hand easily, can infiltrate along rock wool on the one hand, these uncertain factors are easy to cause high temperature silicon liquid to contact with the direct of body of heater stainless steel, and unpredictable damage takes place.For example: local burn through body of heater, local softening body of heater stainless steel, destroy due intensity of skiving body of heater or the like.

Summary of the invention

The utility model purpose provides a kind of reasonable in design, and is easy to use, can effectively avoid the silicon liquid overflow receiving device of the polycrystalline silicon ingot or purifying furnace of body of heater damage.

The utility model is the silicon liquid overflow receiving device of polycrystalline silicon ingot or purifying furnace, comprises body of heater, it is characterized in that the bottom of body of heater is provided with silicon liquid overflow receiving container, is provided with the Metal Melting fracture of wire of tape controller in the silicon liquid overflow receiving container.

The bottom of described body of heater also can be provided with rock wool, and silicon liquid overflow receiving container places on the rock wool, with the protection effect of further raising to body of heater.

Also can be equipped with lining in the described silicon liquid overflow receiving container, the Metal Melting fracture of wire places the surface of lining.

The utility model is reasonable in design, the crucible that can effectively prevent to take up silicon liquid is breaking or other reason when causing the silicon hydrorrhea to go out, the silicon liquid that flows to bottom of furnace body is piled up at bottom of furnace body, and high temperature silicon liquid heat energy burns the body of heater steel plate, thereby the phenomenon that causes catastrophic failure takes place.Avoided of the damage of silicon liquid to body of heater.

Description of drawings

Fig. 1 is an overall structure cutaway view of the present utility model;

Structure cutaway view when Fig. 2 is the utility model user mode.

The specific embodiment

The utility model mainly by the body of heater 5 of band rock wool 6, places the silicon liquid overflow receiving container 1 on the body of heater 5 bottom rock wools 6, places the lining 2 in the silicon liquid overflow receiving container 1 and the formations such as Metal Melting fracture of wire 3 of tape controller 4; Controller 4 places outside the body of heater 5.

When silicon hydrorrhea stream took place, the silicon liquid 7 that leaks down by direction of arrow stream shown in the accompanying drawing 2 accumulated in the lining 2 above the silicon liquid overflow receiving container 1, equivalent proportion more after a little while, silicon liquid is slowly in the lining surface solidification; When equivalent proportion is big, part silicon liquid slowly infilters toward the lining the inside, because container has good thermal diffusivity, the part silicon liquid that infilters also can slowly solidify, and the silicon liquid above stoping continues to infiltrate in lining, in a single day flow in the silicon liquid overflow receiving container 1 owing to silicon liquid simultaneously, the fusible link 3 that can fuse in time produces silicon hydrorrhea stream and reports to the police, at this moment, apparatus control system enters cooling stage rapidly, and the silicon liquid that impels overflow is cooled and solidified as early as possible.
