Shoulder profile, beneficial to the small furnace cover structure of growing large-size, the large-size sapphire single-crystal stove of high-quality sapphire single-crystal.
What the purpose of this utility model was realized in：It includes observation window, observation window baffle plate, the circle passed through for seed rod
Water route dividing plate and cooling water outlet and inlet elbow water nozzle in shape through hole, bell, observation window are distributed in and 9 positions of small furnace cover at 6 points,
Vertical direction is provided with angle, sapphire eyeglass is covered on window；Observation window baffle plate uses molybdenum sheet, the position contacted with small furnace cover
Put and sealed with sealing ring；The manhole at small furnace cover center is available for seed rod by the way that upper internal threaded hole is connected with bellows；It is small
Bell inner chamber median septum is distributed in the shape of a spiral, and middle Cooling Water passes through；There is latticed mistake inside cooling water outlet and inlet water nozzle
Device is filtered, prevents debris from entering inside small furnace cover, blocks water route, influences cooling effect.
The utility model also has so some features：
1st, described observation window is a diameter of 20 ~ 40mm pipe, and vertical positioned at 6 points of small furnace cover and 9 directions
There is 10 ° ~ 20 ° of angle in direction, and top is installed the thick sapphire eyeglasses of 5 ~ 15mm, sealed with nut.
2nd, described observation window baffle plate is connected by molybdenum nut with connecting rod, had on the outside of bell using molybdenum plate thick 3 ~ 8mm
Realization switch is moved in serial verb construction, left and right.
3rd, the manhole internal diameter at described bell center is 50 ~ 100mm, top edge have 4 ~ 8 round diameters for M6 ~
M12 internal thread hole, is fixed with expansion corrugated pipe.
4th, the water route dividing plate in described bell inner chamber is arranged in the shape of a spiral, and thickness is 2 ~ 5mm, Cooling Water between dividing plate
Pass through.
5th, described cooling water outlet and inlet tap diameter is 4 points or 6 points, internally places one layer of netted filtering device.
The utility model beneficial effect has：
1. in a kind of small furnace cover structure of large-size sapphire single-crystal stove of the utility model, the spiral shell of port cover cavity median septum
Shape distribution design is revolved, film-cooled heat can be increased, cooling effect is more preferable.
2. in a kind of small furnace cover structure of large-size sapphire single-crystal stove of the utility model, cooling water is by bell center
Into marginal position is flowed out, and stove internal upper part radial symmetry gradient can be made more reasonable, optimizes crystal shoulder profile.
In a kind of small furnace cover structure of large-size sapphire single-crystal stove of the utility model, pacify inside cooling water outlet and inlet water nozzle
Netted filtering device is filled, impurity can be effectively reduced and enter inside small furnace cover, avoid the situation of blocking pipeline from occurring.
