Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail:
As shown in Figure 1, be provided with three graphite column open holess bottom the body of heater 5 of polycrystalline furnace, three graphite columns 15 are arranged on graphite column open holes, and the top of graphite column 15 is provided with warming plate 6, are covered with asbestos layer 7 bottom the body of heater 5 of polycrystalline furnace.Silicon leakage of polycrystalline silicon ingot furnace monitoring and safety guard comprise overflow silk 10, seal assembly 9, mullite shade assembly 13, keel assembly 14, mullite 11 and PLC module 8.Keel assembly 14 is located at the lower outside of graphite column 15, mullite 11 is housed between graphite column 15 and keel assembly 14, the body of heater 5 bottom pumping mouth 12 of polycrystalline furnace is provided with mullite shade assembly 13, mullite 11 is housed between bleeding point 12 and mullite shade assembly 13, keel assembly 14 and mullite shade assembly 13 surrounding are covered with mullite 11, mullite 11 is a kind of high temperature materials, still very stable 1800 DEG C time.The top of asbestos layer 7 is covered with overflow silk 10, as shown in Figure 2, overflow silk 10 in three-back-shaped, the Stainless Steel Wire of to be diameter be 1.2 ~ 1.5mm.Overflow silk 10 is connected with the PLC module 8 being arranged on polycrystalline furnace body of heater 5 outside by two seal assemblies 9, when described seal assembly 9 principal security overflow silk 10 passes in and out body of heater 5 and body of heater 5 not conducting, and does not affect the stopping property of body of heater 5 entirety.Described PLC module 8 is communicated with overflow silk 10 by wire, a signal is produced when overflow silk 10 loop fuses, feed back to PLC module 8, according to the program trigger alarm that PLC inside sets in advance, and automatically enter the urgent cooling mode of polycrystalline furnace in tape program, here PLC module 8 is prior art, specifically selects that brand is Omron, model is the PLC of CJ1W-ID211, can realize required function.As shown in Figure 4 keel assembly 14 by 1 keel a22,3 keel b23 and 1 keel c24 is stacking forms, it is inside and outside lays mullite 11, and protection graphite erection column is not easily fused when leaking silicon.Mullite shade assembly 13 is made up of 1 mullite cover a16,1 mullite cover b17,5 mullite cover c18,3 mullite cover d19,1 mullite cover e20 and 1 mullite cover f21 as shown in Figure 3; also lay mullite 11 inside and outside it, protection bleeding point 12 is not easily fused when leaking silicon.
The position of the easiest burn through of general body of heater 5 is three the graphite column position of mounting hole being welded on furnace bottom, if the fusing of this position, DS block 4 will be caused to offset, and the high temperature silicon liquid in whole crucible 3 will be dumped and have an accident.Be exactly thin-walled place in addition; mainly bleeding point 12 position; this position is directly communicated with air; because being high-temperature vacuum state in body of heater 5; to ambient atmosphere be caused to enter body of heater 5 fast if be fused; the carbon containing objects such as body of heater 5 internal heater will be caused to meet oxygen blast, so these positions will be laid special stress on protecting when leaking silicon.When leaking silicon and occurring, gap by crucible guard boards assembly 2 is oozed out by silicon liquid, being flowed out by the overflow weir of warming plate 6 to enter bottom body of heater 5 on asbestos layer 7, because body of heater 5 is end enclosure structures, silicon liquid will middlely bottom body of heater 5 be gathered, because bleeding point 12, three graphite column open holes surroundings are covered with mullite 11, between bleeding point 12 and mullite shade assembly 13 and between graphite column 15 and keel assembly 14, also mullite 11 is all housed.Under normal circumstances; mullite 11 is suitable with the temperature of 200 DEG C ~ about 500 DEG C, furnace wall; when leaking silicon; the gap that the high temperature silicon liquid of about 1420 DEG C will flow through between mullite 11; mullite 11 is high temperature material; can absorb rapidly heat and make high temperature silicon liquid rapid crystallization, these four hazardous locations of protection are difficult to burn through in time.Simultaneously; because overflow silk 10 is arranged on asbestos layer 7, silicon liquid will flow through overflow silk 10, because silicon liquid temp is very high; overflow silk 10 is caused to fuse; trigger the PLC module 8 be connected with overflow silk 10 to report to the police, make production sequence enter urgent cooling mode, system will cut off heating installation power supply; and then cool stove fast; excess silicon liquid is condensed, to avoid security incident, proterctive equipment and personal security.
Finally, it should be noted that above what enumerate is only specific embodiment of the utility model.Obviously, the utility model is not limited to above embodiment, can also have a lot of distortion.All distortion that those of ordinary skill in the art can directly derive or associate from content disclosed in the utility model, all should think protection domain of the present utility model.
