Abstract
The invention relates to a cooling water collector of a sapphire crystal growth furnace. The cooling water collector is characterized by comprising a collector shell (1), wherein the top of the collector shell (1) is connected with a plurality of cooling water branch pipes (2) which are in staggered arrangement and extend into the collector shell (1); a temperature thermocouple (3) is arranged on each cooling water branch pipe (2); a viewing window (4) is arranged on the front surface of the collector shell (1) by virtue of a hinge; the bottom of the collector shell (1) is connected with a collector water outlet pipe (6). The cooling water collector of the sapphire crystal growth furnace, disclosed by the invention, has the advantages of accurately controlling the temperature of each cooling water branch, exhausting the air in a cooling water pipeline in time, and ensuring the cooling effect of cooling water as well as the safety.
Description
Technical field
The present invention relates to the long brilliant stove of a kind of sapphire, relate in particular to the long brilliant stove water coolant manifold of a kind of sapphire, belong to sapphire technical field.
Background technology
Sapphire is AL
2o
3single crystal, have that fusing point is high, hardness is high, thermal conductivity is good, see through the features such as optical band is wide, electrical insulating property good, strong alkali-acid resistance corrosion, therefore as important technology crystalline material, be widely used in a series of high-tech technical fields such as national defence, military affairs, scientific research, in civilian industry, also there is a large amount of application, as photodiode, microelectronic circuit, optical sensing, fiber waveguide device and LED energy-saving field simultaneously.2016, to thoroughly eliminate and use general lighting incandescent light, between in the past 130 years, nowadays will withdraw from the market for the mankind bring bright incandescent light, take over it relay baton be the better also LED electricity-saving lamp of power saving more of illuminating effect, so sapphire market outlook are wide.
The production method of sapphire crystal has multiple: crystal pulling method (Chai Shi crystal pulling method), kyropoulos (the long brilliant method of Kai Shi) and temperature gradient method etc., this several method, no matter any long crystal method, all need heating raw materials to 2100 DEG C left and right, by raw material fusing, after impurities removal after a while, again melt is slowly cooled to 2050 DEG C of left and right, after reaching the optimum temps of seeding, start seeding, then through expanding shoulder, isodiametric growth, a series of step such as cooling, until long brilliant end.In this process; because thermal field center is very high; thermal field surrounding is furnished with housing, bell, cover, copper supporting disk etc., and the use temperature of the making material of these parts all cannot reach the high temperature of 2050 DEG C, and this just need to protect by water-cooled mode the safety of each several part.Good thermograde of crystal growth needs, the form of traditional cooling water pipeline is varied, and water resistance and the temperature of each branch road cooling water pipeline are not quite similar, be difficult to accurately control each water coolant branch road temperature, and in cooling water pipeline, can there is the most at the beginning a large amount of air, if can not get rid of in time cooling performance and the safety that can affect water coolant.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, provide one can accurately control each water coolant branch road temperature, and air in cooling water pipeline can get rid of in time, ensure the cooling performance of water coolant and the long brilliant stove water coolant manifold of the sapphire of safety.
The object of the present invention is achieved like this:
The long brilliant stove water coolant manifold of a kind of sapphire, it comprises manifold housing, the top of described manifold housing is connected with the many water coolant arms that dislocation is arranged, many water coolant arms stretch into manifold enclosure interior, on described water coolant arm, temperature thermocouple is installed, the front of described manifold housing is provided with form by hinge, and the bottom of described manifold housing is connected with manifold rising pipe.
The manifold housing of described form top is provided with water-cooled tube branch road label.
Compared with prior art, the invention has the beneficial effects as follows:
The long brilliant stove water coolant manifold of sapphire of the present invention has can accurately control each water coolant branch road temperature, and air in cooling water pipeline can get rid of in time, ensures the cooling performance of water coolant and the advantage of safety.

Embodiment
Referring to Fig. 1 and Fig. 2, the long brilliant stove water coolant manifold of a kind of sapphire the present invention relates to, it comprises manifold housing 1, the top of described manifold housing 1 is connected with the many water coolant arms 2 that dislocation is arranged, many water coolant arms 2 stretch into manifold housing 1 inside, described water coolant arm 2 has 1 ~ 15, on described water coolant arm 2, temperature thermocouple 3 is installed, the front of described manifold housing 1 is provided with form 4 by hinge, the manifold housing 1 of described form 4 tops is provided with water-cooled tube branch road label 5, described form 4 can rotate along hinge, facilitate the inspection of water coolant arm 2, the bottom of described manifold housing 1 is connected with manifold rising pipe 6.
Principle of work: when work first by clean AL
2o
3raw material pack in crucible, again the inside thermal field of long brilliant stove is in place, close after fire door, open the total valve of water coolant, water coolant enters each water coolant arm after the long brilliant stove water dispenser uniformly distributing of sapphire of system, unnecessary air in each water coolant arm is entered to the long brilliant stove water coolant manifold of sapphire, open form by outside long unnecessary Bas Discharged brilliant stove.Temperature thermocouple on the long brilliant stove water coolant manifold of sapphire is for measuring the temperature signal of each water coolant arm, and inputed to the long brilliant furnace control system of sapphire, regulated the flow of each water coolant branch road on the long brilliant stove water dispenser of sapphire according to the temperature of cooling water of each water coolant arm by Controlling System, thereby obtain being applicable to the thermograde of crystal growth, the loop condition of water coolant can observe each water coolant arm by form at any time in long brilliant stove operational process in, can also prevent spray of water, can carry out artificial temperature survey simultaneously, thermometric effect to temperature thermocouple is verified, water coolant in all water coolant arms enters after manifold housing, in manifold housing, fully mix, manifold rising pipe by manifold housing bottom enters water return pipeline, final inflow place lower condensate sump carries out cooling process.
