Description
Technical field
The utility model relates to LED fluorescent powder production technical field, is specially a kind of heating furnace produced for LED fluorescent powder.
Background technology
At present, the production technology main production equipments of the yellowish green powder of existing LED fluorescent powder is heating furnace, a small amount of raw material is put into crucible, crucible is heated, make crucible thermally equivalent, but time raw material is many, there will be material district, middle part and the larger situation of surrounding material district temperature difference, a same batch products, quality has larger difference, cause waste, the heating furnace that existing LED fluorescent powder is produced is all heated doing with Si-Mo rod mostly.
The resistive heating of Si-Mo rod is a kind of high temperature resistant, oxidation resistant resistance heating element made based on molybdenum disilicide.When using under high temperature oxidation stability atmosphere, the quartz glass film that Surface Creation one deck light is fine and close, Si-Mo rod internal layer can be protected not reoxidize, and therefore Si-Mo rod element has unique high-temperature oxidation resistance.Under oxidizing atmosphere, maximum operation (service) temperature is 1800 DEG C, and the resistance of Si-Mo rod heating raises along with temperature and increases sharply, and when temperature-resistant, resistance value is stablized.Component resistance does not change with the length of service time under normal circumstances, and therefore, new and old Si-Mo rod heating can be used in combination.
In the heating furnace casing that existing LED fluorescent powder is produced, Si-Mo rod arranges in the left and right sides, the side of facing, when the large content of starting materials of sintering, because raw material itself has certain thermal resistance, the raw material sintering temperature near Si-Mo rod can be caused higher, and the temperature of centre is lower, does not reach or exceed suitable reaction temperature, product may be directly defective, reduce the production capacity of product, so we propose a kind of heating furnace produced for LED fluorescent powder.
Utility model content
The purpose of this utility model is to provide a kind of heating furnace produced for LED fluorescent powder, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme: a kind of heating furnace produced for LED fluorescent powder, comprise heating furnace casing, described heating furnace box house both sides are all installed with the first Si-Mo rod, described heating compartment center of inside is also installed with the second Si-Mo rod, heating furnace casing is divided into the first heating clamber and the second heating clamber by described second Si-Mo rod, nine crucibles are provided with in described first heating clamber and the second heating clamber, and nine crucibles become array arrangement respectively in the first heating clamber and the second heating clamber, the outer surface of institute's heating furnace casing is enclosed with heat-insulation layer, the outer surface of described heat-insulation layer is also provided with macromolecule heat insulating coat.
Preferably, the quantity of described first Si-Mo rod is provided with two, and two the first Si-Mo rods are symmetrical arranged about the second Si-Mo rod of heating furnace casing central authorities.
Preferably, described crucible array arrangement is between the first Si-Mo rod and the second Si-Mo rod.
Preferably, one end of described first Si-Mo rod and the second Si-Mo rod is all fixedly connected on the same side inwall of heating furnace casing.
Compared with prior art, the beneficial effects of the utility model are: this heating furnace structure being used for LED fluorescent powder production is simple, reasonable in design, compare and the heating furnace being conventionally used to LED fluorescent powder and producing, row's silicon molybdenum side has been added at the middle part of heating furnace casing, heating compartment middle portion temperature is promoted to some extent, the each space of whole burner hearth is heated comparatively even, not only bring up to reaction efficiency, product production capacity also significantly improves, and by being arranged on the heat-insulation layer of heating furnace box outer surface, effectively can guarantee can not to run off in the outside in antipyretic stove casing, be conducive to increasing work efficiency, by being arranged on the macromolecule heat insulating coat of heat-insulation layer outer surface, effectively can completely cut off casing high temperature, avoid staff to touch casing because of carelessness and occur scalding.
