Abstract
The invention discloses an impurity removal device for removing a volatile matter on the surface of a solution. The impurity removal device comprises a support; the support is provided with two metal bellows; the two bellows are connected by a tray; the upper end of the higher bellow is fixedly connected with the upper end of the support; the lower end of the lower bellow is fixedly connected wit the lower end of the support; the tray is provided with a handle; the handle is arranged on the outer sides of the bellows; the tray is also provided with a metal bar; the metal bar is arranged in the lower bellow; when moving downwards, the metal bar can extend out of the lower bellow; and the two bellows, the tray and the support form a cavity with the lower end of the lower bellow being communicated with the outside. Because the volatile matter can be cooled down, the volatile matter can be condensed on the metal bar and finally taken out along with the metal bar without affecting the growth of the crystal.
Description
Technical field
The present invention relates to a kind of knot screen.
Background technology
At present; In monocrystalline, especially the sapphire crystal growth process, the liquation top layer is prone to produce volatile matter during the raw material fusing; The composition of volatile matter mainly contains tungsten, molybdenum, aluminum oxide etc.; These volatile matters can influence seeding, even also influence the crystalline growth quality, and these volatile matters are lifting the lifting that also can hinder other device after condensing in mouthful place on the crucible pot cover.Original way is that these volatile matters of leaving rest in the crucible, so the crystal mass of producing is not high yet.
Summary of the invention
Technical problem to be solved by this invention is: a kind of knot screen of removing solution top layer volatile matter is provided.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of knot screen comprises support; Vertically be provided with two metallic bellowss on the said support; Link to each other through pallet between two corrugated tubes, the upper end that is positioned at the corrugated tube of top is fixedly connected with the support upper end, and the lower end that is positioned at the corrugated tube of below is fixedly connected with the support lower end; Pallet is provided with handle; And handle is positioned at the corrugated tube outside, also is provided with Metallic rod on the pallet, and Metallic rod is positioned at the corrugated tube of below; And stretch out in the corrugated tube below Metallic rod moves down Shi Kecong, form one between two corrugated tubes, pallet and the support and have only corrugated tube lower end, below and the extraneous cavity that communicates.
The invention has the beneficial effects as follows: utilize the cooling down property of volatile matter, it is condensed on the Metallic rod, take out with Metallic rod at last, avoided the influence of volatile matter crystal growth.
Description of drawings
Fig. 1 is the structure iron of knot screen of the present invention.
Among the figure: 1, support, 2, go up corrugated tube, 3, corrugated tube down, 4, pallet, 5, handle, 6, Metallic rod.
Embodiment
Below in conjunction with accompanying drawing, describe specific embodiments of the present invention in detail.
As shown in Figure 1, knot screen of the present invention comprises support 1; Vertically be provided with two metallic bellowss on the said support 1---go up corrugated tube 2 and following corrugated tube 3; Link to each other through pallet 4 between last corrugated tube 2 and the following corrugated tube 3, the upper end of last corrugated tube 2 is fixedly connected with support 1 upper end, and the lower end of following corrugated tube 3 is fixedly connected with support 1 lower end; Pallet 4 is provided with handle 5; And handle 5 is positioned at the corrugated tube outside, also is provided with Metallic rod 6 on the pallet 4, and Metallic rod 6 is positioned at corrugated tube 3 down; And when Metallic rod 6 moves down under the Shi Kecong and stretches out in the corrugated tube 3, last corrugated tube 2, form a cavity that has only following corrugated tube 3 lower ends and the external world to communicate between corrugated tube 3, pallet 4 and the support 1 down.
Principle of work of the present invention is: will be installed on the pot cover of crucible by the invention knot screen, and make corrugated tube 2, communicate in the cavity of formation and the crucible between corrugated tube 3, pallet 4 and the support 1 down, the volatile matter in operator observe crucible more for a long time; Downward driving handle 5, handle 5 drives Metallic rod 6 through pallet 4 and moves down, and is arranged in volatile matter until the lower end of Metallic rod 6; Because the temperature of Metallic rod 6 is lower than the temperature in the crucible, volatile matter will condense on Metallic rod 6, after volatile matter has condensed; Release handle 5; Pallet 4 resets under the elastic force of last corrugated tube 2 and following corrugated tube 3, and promptly Metallic rod 6 is taken the agglomerative volatile matter out of in crucible, and rests on down in the corrugated tube 3; Growth exerts an influence to crystalline to have avoided volatile matter, and has improved the crystalline quality.Because pallet 4 is between last corrugated tube 2 and following corrugated tube 3, so resetting of pallet 4 can be very inviolent.
Claims (1)
1. knot screen comprises support, it is characterized in that: vertically be provided with two metallic bellowss on the said support; Link to each other through pallet between two corrugated tubes, the upper end that is positioned at the corrugated tube of top is fixedly connected with the support upper end, and the lower end that is positioned at the corrugated tube of below is fixedly connected with the support lower end; Pallet is provided with handle; And handle is positioned at the corrugated tube outside, also is provided with Metallic rod on the pallet, and Metallic rod is positioned at the corrugated tube of below; And stretch out in the corrugated tube below Metallic rod moves down Shi Kecong, form one between two corrugated tubes, pallet and the support and have only corrugated tube lower end, below and the extraneous cavity that communicates.
