Abstract
The utility model relates to a quartz feeding device of a single crystal furnace. A bracket of the device is horizontally erected on a feeding cylinder, a movable loop bar is positioned in the feeding cylinder and arranged on the bracket, the lower end of the movable loop bar is connected with a cone, the diameter of the bottom surface of the cone is greater than or equal to that of the feeding cylinder. The quartz feeding device can be temporarily suspended in the single crystal furnace through the movable loop bar and the bracket, feeding is conducted directly under the high-temperature state of the single crystal furnace without the need of fully cooling the single crystal furnace, thereby being fast and convenient, capable of improving the working efficiency, and incapable of causing the metal pollution of single crystals.
Description
Technical field
The utility model relates to the quartzy feeding device of a kind of single crystal growing furnace.
Background technology
At present, single crystal growing furnace is reinforced adopts metal vessel usually, although adopt metal vessel reinforced fast and simple, maximum shortcoming is to cause the metallic pollution of monocrystalline, has a strong impact on the monocrystalline inner quality.
Summary of the invention
The purpose of this utility model is to provide can accelerate feed rate, increases work efficiency, improves the quartzy feeding device of a kind of single crystal growing furnace of monocrystalline quality.
The technical scheme that the utility model is taked is: the quartzy feeding device of a kind of single crystal growing furnace, it is characterized in that it comprises movable loop bar, support, casing drum and cone, the support crossbearer is on casing drum, movable loop bar is arranged in casing drum and is arranged on support, the lower end of movable loop bar is connected with cone, and the bottom surface diameter of cone is more than or equal to the diameter of casing drum.
Adopt the utility model, can this device be lifted in single crystal growing furnace by movable loop bar and support temporarily, directly feed in raw material under the single crystal growing furnace condition of high temperature, need not to make single crystal growing furnace fully cooling, not only fast but also convenient, can increase work efficiency, and can not cause again the metallic pollution of monocrystalline.
Description of drawings
Fig. 1 is schematic diagram of the present utility model.
Sequence number in figure represents: movable loop bar 1, support 2, casing drum 3 and cone 4.
Embodiment
The utility model is described in further detail below in conjunction with specific embodiment.
With reference to Fig. 1, it comprises movable loop bar 1, support 2, casing drum 3 and cone 4 the quartzy feeding device of this single crystal growing furnace, support 2 crossbearers are on casing drum 4, movable loop bar 1 is arranged in casing drum 3 and is arranged on support 2, the lower end of movable loop bar 1 is connected with cone 4, and the bottom surface diameter of cone 4 is more than or equal to the diameter of casing drum 3.During use, adopt high temperature resistant high purity quartz material to make casing drum 3, when if single crystal growing furnace need to feed in raw material, can first add from top to bottom the silicon material at casing drum 3, then be lifted on this device in single crystal growing furnace by movable loop bar 1 and support 2 temporarily, again cone 4 is opened downwards, the silicon material can fall into single crystal growing furnace from the space between cone 4 and casing drum 3, like this, need not to begin to feed in raw material in the situation that single crystal growing furnace is fully cooling, not only fast but also convenient, can increase work efficiency, can not cause again the metallic pollution of monocrystalline.
