Description
Technical field
The utility model relates generally to the quartz crucible production equipment for drawn monocrystalline silicon, is specifically related to a kind of quartz crucible forming mould.
Background technology
Silicon single crystal is the main raw of conversion solar energy, electric energy.Crystalline silicon material (comprising polysilicon and silicon single crystal) is topmost photovoltaic material, and its share of market more than 90%, and is also still the mainstay material of solar cell in one quite long from now on period.High-purity silicon single crystal rod is the raw material of single crystal silicon solar cell, silicon purity requirement 99.999%.
Quartz crucible is the expendable vessel of drawn monocrystalline silicon, often produces a stove silicon single crystal and just to use up a quartz crucible.Quartz crucible is the crucial requisite of monocrystalline silicon production.Therefore the demand of silicon single crystal and the demand of quartz crucible are directly proportional.The whole nation needs crucible quantity 280-360 about ten thousand in silicon single crystal industry year.Current domestic yearly capacity is only 2,000,000, far can not meet the demand of domestic silicon single crystal industry.
At present, the production unit used during domestic quartz crucible manufacturing enterprise produces comes from the production unit introduced from Japan the beginning of the seventies in last century, and this technical equipment level of automation is not high, and in whole production process, more dependence manually realizes.
The core technology of producing quartz crucible is to found mould.Current mould of founding mainly adopts graphite jig and punching block mould, its ubiquitous problem mainly contain following some: 1. glass melting temperature is lower, is difficult to reject the metallic impurity in raw material; 2. need to install water jacket additional, mould resistance to elevated temperatures is poor; 3. die life is shorter, about each graphite jig can found 200 crucibles, and also can only reach about 600 with the punching block mould of pig iron casting; 4. starting material require higher, can not the lower domestic quartz sand of using character, can only the import quartz sand of Price-dependent costliness; 5. melting time is longer, and production efficiency is low; 6. energy consumption is too high, and electricity charge burden is heavier.
Along with the recovery of photovoltaic industry, based on material prepare container, quartz crucible must towards high-quality, less energy-consumption, major diameter, high crystal pulling success ratio future development, the fast development of photovoltaic industry to English crucible in major diameter, high purity, bubble is few, Impurity Distribution high uniformity, specification precision are high, the professional domains such as heat resistance is good are had higher requirement.Core technology again owing to preparing quartz crucible is to found mould, and therefore, the appearance of founding mould in the urgent need to a kind of new quartz crucible is filled a hole in the market.
Summary of the invention
The purpose of this utility model is the drawback solving prior art existence, provides the quartz crucible forming mould that a kind of intensity is high, long service life, power consumption are low, save energy, number of bubbles are few, with short production cycle, cost is low again.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of quartz crucible forming mould, comprise metal alloy mould mould, outer mold, porous alloy base, universal stage, turning axle, the skin cover of described metal alloy mould has outer mold, porous alloy base is equipped with in the bottom of described metal alloy mould, described porous alloy base is placed on universal stage, is provided with turning axle below described universal stage.Wherein, a cavity is formed between described metal alloy mould and described outer mold, described universal stage is equipped with vacuum pipe, described vacuum pipe communicates with described cavity and passes the centre hole of outer mold and metal alloy mould, and described vacuum pipe accumulates a vacuum pipe in interior of rotating shaft and is connected with outside off-gas pump.
Described metal alloy mould is provided with multiple micro-pore.
Described outer mold eliminates the circulating chilled water device of original water jacket.
What described outer mold inside was filled is silica wool.
The beneficial effect that the utility model produces is: on the one hand, the utility model passes through the improvement of founding mold material, adopt tungsten Zinc alloy die, improve mould strength, mould can not be burst in high temperature melting process, reduce consumption and the thermal treatment energy consumption of mould, decrease energy dissipation, extend die life.On the other hand, the utility model is by the improvement of mold sandwich, solve the water jacket that traditional moulds outside need be provided as mould cooling, circulation cycle water in water jacket, circulating water pool and water circulating pump must be had, and to the cooling demoulding be carried out when product has founded the demoulding, this Mould operation is complicated, production cost is high, the consumption of moulding stock and the high problem of thermal treatment energy consumption.The utility model adopts insulation silica wool, and solving mold exterior need provide water jacket to lower the temperature, and causes the waste of thermal treatment energy consumption, the drawback that production cost is high, after improving, efficiently solve calorific loss, improves heat utilization rate.The utility model improves the vacuum tightness of mold system, reduces the striking voltage of electrode bar simultaneously.The lifting of pressure can make the combination between quartz sand particle more tight, greatly reduces the space reduced between particle and particle like this, thus reduces the probability that bubble occurs to a great extent, improve the drawing crystal forming rate of drawn monocrystalline silicon.In addition, the utility model also improves glass melting temperature, can to remove on the one hand in domestic quartz sand raw material the metallic impurity such as lithium, aluminium, potassium, sodium fast, and solving raw material can only the drawback of dependence on import quartz sand, significantly reduces production cost.On the other hand, after in mould, temperature improves, the liquefied that product quartz crucible inner surface presents is more thorough, reduce the viscosity of liquid quartz, the bubble of liquid quartz inside, crucible internal skin is discharged fast, reach and remove bubble fast, the outer quartz sand particle of quartz crucible is combined closely, improve the intensity of product quartz crucible, improve quality product simultaneously, shorten the production cycle, save melting time, single finished product melting time is made to reduce to 9 minutes, improve production efficiency, utilization rate of raw materials brings up to more than 85%, reduce production cost, really reach energy-saving and cost-reducing object.
