Abstract
A water jacket of a quartz crucible comprises a water jacket casing, wherein a cooling water cavity is arranged in the water jacket casing, a supporting ring is arranged on the inner wall of the water jacket casing, and an air extraction port and cooling water cavity ports are arranged at the bottom of the water jacket casing. The water jacket of the quartz crucible is characterized in that the cooling water cavity ports are evenly distributed at the edge of the bottom surface of the water jacket casing. The cooling water cavity ports are located at the edge of the bottom surface of the water jacket casing and far away from the air extraction port, so that cooling water is prevented from being heated by high-temperature air extracted by the air extraction port, cooling efficiency is high, and cooling effect is good. In addition, when leakage happens to the cooling water cavity ports, the cooling water cannot be vaporized by the high-temperature air, the vacuum degree of the environment where the quartz crucible is located is ensured, and the rejection rate of the quartz crucible is reduced.
Description
Technical field
The utility model relates to a kind of quartz crucible water jacket that uses in the quartz crucible process of producing.
Background technology
The quartz crucible water jacket is to produce to be used to support the quartz crucible mould in the quartz crucible process, cooling to be provided, to guarantee that quartz crucible is in the equipment of vacuum environment for quartz crucible.Existing quartz crucible water jacket comprises the water jacket housing, is provided with support ring in inner walls, and the water jacket enclosure interior is a cooling water cavity, is provided with bleeding point and water coolant accent in lower housing portion, and described water coolant accent is distributed on around the bleeding point.When quartz crucible is arranged in the quartz crucible mould, vacuum extractor by bleeding point with being evacuated the quality that influences quartz crucible to avoid containing bubble in the quartz crucible between quartz crucible water jacket and quartz crucible; By the cooling water cavity interface water coolant is provided in cooling water cavity, so that red-hot quartz crucible is finalized the design faster.Because the extreme temperatures of the air between quartz crucible and water jacket causes water coolant to be heated at water coolant accent place, cooling performance is poor, and evaporation efficiency is low.In case and water coolant accent place leaks, water coolant be vaporized after high temperature air mixes, get between quartz crucible water jacket and the quartz crucible, can destroy vacuum environment, even can cause the quartz crucible bottom protrusion, scrap rate is high.
Summary of the invention
The technical problem that the utility model will solve provides a kind of good cooling results, evaporation efficiency height, can guarantee quartz crucible environment vacuum tightness of living in, the quartz crucible water jacket that the quartz crucible scrap rate is low.
The utility model is achieved in that
A kind of quartz crucible water jacket; Comprise the water jacket housing, the water jacket enclosure interior is a cooling water cavity, is provided with support ring in the water jacket inner walls; Be provided with bleeding point and water coolant accent at the water jacket housing bottom, its special character is: described water coolant accent is distributed on the edge of water jacket housing bottom surface.
Described water coolant accent has four.
The beneficial effect of the utility model is: because the water coolant accent is positioned at the edge of water jacket housing bottom surface; Away from bleeding point, avoided water coolant in the high temperature air heating of being extracted out via bleeding point, evaporation efficiency is high, good cooling results; In case and leak at water coolant accent place; Water coolant can not vaporized by high temperature air, has guaranteed quartz crucible environment vacuum tightness of living in, has reduced the scrap rate of quartz crucible.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: water jacket housing 1, support ring 2, water coolant accent 3, bleeding point 4.
Embodiment
As shown in the figure; This quartz crucible water jacket; Comprise water jacket housing 1, water jacket housing 1 inside is cooling water cavity, is provided with support ring 2 at water jacket housing 1 inwall; Be provided with water coolant accent 3 and bleeding point 4 in water jacket housing 1 bottom, described water coolant accent 3 has four and be distributed on the edge of water jacket housing 1 bottom surface.
During work, vacuum extractor is extracted the air between quartz crucible water jacket and the quartz crucible mould out through bleeding point 4, forms vacuum environment, the quality that influences quartz crucible to avoid containing bubble in the quartz crucible.In cooling water cavity, inject water coolant through water coolant accent 3, make it rapid shaping with the cooling quartz crucible.
Claims (2)
1. quartz crucible water jacket; Comprise the water jacket housing, the water jacket enclosure interior is a cooling water cavity, is provided with support ring in the water jacket inner walls; Be provided with bleeding point and water coolant accent at the water jacket housing bottom, it is characterized in that: described water coolant accent is distributed on the edge of water jacket housing bottom surface.
2. quartz crucible water jacket according to claim 1 is characterized in that: described water coolant accent has four.
