Description

TECHNICAL FIELD

[0001] The present disclosure relates to the field of germanium materials, and more particularly to a germanium ingot placing rack. BACKGROUND

[0002] Before high-purity germanium polycrystalline zone melting and single crystal pulling, the raw material germanium ingot needs to be subjected to etching treatment. For example, Chinese patent document CN113718257A published on November 30, 2021, wherein the etched germanium ingot is placed in a pure water tank for repeated rinsing and nitrogen blowing.

[0003] The nitrogen blowing process is as follows: the operator wears a hundred-level clean glove on both hands, holds the germanium ingot rinsed with pure water with one hand, and holds a nitrogen gun with the other hand, and blows dry the germanium ingot in a hundred-level clean table.

[0004] This hand-held nitrogen blowing causes the hand-held part of the germanium ingot to be unable to be directly blown dry, and requires the previously hand-held part to be blown dry after the germanium ingot is blown dry except for the hand-held part, which causes inconvenience and reduces efficiency.

[0005] In addition, since the hand-held nitrogen blowing is adopted, the operator needs to change the posture of the hand holding the germanium ingot to blow dry the germanium ingot without dead angles, which reduces the operation efficiency, and the residual pure water on the surface of the germanium ingot may flow back under the impact of nitrogen due to the change of the posture, increasing the probability of residual pure water on the germanium ingot.

[0006] In addition, even if the operator wears a hundred-level clean glove on both hands, impurities from the hundred-level clean glove may be left on the surface of the germanium ingot during contact with the germanium ingot, which is not conducive to improving the product quality of high-purity germanium polycrystalline zone melting and single crystal pulling. CONTENT OF THE UTILITY MODEL

[0007] In view of the problems in the background art, an object of the present disclosure is to provide a germanium ingot placing rack which can improve the operation efficiency of nitrogen blowing of the germanium ingot.

[0008] Another object of the present disclosure is to provide a germanium ingot placing rack which can avoid the phenomenon of residual water flowing back under the impact of nitrogen.

[0009] Still another object of the present disclosure is to provide a germanium ingot placing rack which can realize blowing dry of the entire germanium ingot without dead angles.

[0010] Thus, a germanium ingot placing rack is provided, which includes a support rack, the support rack including a bottom plate, a high bar assembly, and a low bar assembly; the high bar assembly including a high support bar, the high bar assembly being fixed to the bottom plate so that the high support bar is suspended above the bottom plate; the low bar assembly including a first low support bar and a second low support bar, the low bar assembly being fixed to the bottom plate so that the first low support bar and the second low support bar are suspended above the bottom plate, the first low support bar, the second low support bar, and the high support bar being spaced apart from each other and parallel to each other in a left-right direction, the first low support bar being higher than the second low support bar in an up-down direction, and the high support bar being higher than the second low support bar in the up-down direction; the first low support bar, the second low support bar, and the high support bar being used together to: the second low support bar and the high support bar supporting a bottom surface of the germanium ingot, and the first low support bar abutting against an end surface of the germanium ingot, so that the germanium ingot is supported and positioned on the first low support bar, the second low support bar, and the high support bar in an inclined manner relative to the bottom plate, for nitrogen blowing dry operation of the germanium ingot.

[0011] The beneficial effects of the present disclosure are as follows.

[0012] In the germanium ingot placing rack according to the present disclosure, by the provision of the first low support bar, the second low support bar, and the high support bar, the second low support bar and the high support bar support a bottom surface of the germanium ingot, and the first low support bar abuts against an end surface of the germanium ingot, so that the germanium ingot is supported and positioned on the first low support bar, the second low support bar, and the high support bar in an inclined manner relative to the bottom plate, for nitrogen blowing dry operation of the germanium ingot, which avoids the posture change operation of the hand-held operation in the background art, and improves the operation efficiency of the nitrogen blowing dry operation of the germanium ingot.

[0013] In addition, since the germanium ingot is supported and positioned on the first low support bar, the second low support bar, and the high support bar in an inclined manner, there is no posture change of the hand holding the germanium ingot as in the background art, which avoids the phenomenon of backflow of residual water under the impact of nitrogen, and only one-way nitrogen blowing dry from the high support bar side to the second low support bar side is needed, eliminating the residual pure water on the germanium ingot.

[0014] In addition, during nitrogen blowing dry, since only one-way nitrogen blowing dry from the high support bar side to the second low support bar side is needed, the entire germanium ingot can be blown dry without dead angle from the high support bar side to the second low support bar side.

[0037] Referring to Figure 1 and Figure 2, The germanium ingot placing rack 100 according to the present disclosure comprises a support frame 1. The support frame 1 comprises a bottom plate 11, a high bar assembly 12, and a low bar assembly 13. The high bar assembly 12 comprises a high support bar 121, and the high bar assembly 12 is fixed on the bottom plate 11 so that the high support bar 121 is suspended above the bottom plate 11. The low bar assembly 13 comprises a first low support bar 131 and a second low support bar 132, and the low bar assembly 13 is fixed on the bottom plate 11 so that the first low support bar 131 and the second low support bar 132 are suspended above the bottom plate 11, the first low support bar 131, the second low support bar 132, and the high support bar 121 are spaced apart from each other and parallel to each other in the left-right direction D2, the first low support bar 131 is higher than the second low support bar 132 in the up-down direction D3, and the high support bar 121 is higher than the second low support bar 132 in the up-down direction D3. The first low support bar 131, the second low support bar 132, and the high support bar 121 together serve to: the second low support bar 132 and the high support bar 121 support the bottom surface 200a of the germanium ingot 200, and the first low support bar 131 abuts against the end surface 200b of the germanium ingot 200, so that the germanium ingot 200 is supported and positioned on the first low support bar 131, the second low support bar 132, and the high support bar 121 in an inclined manner relative to the bottom plate 11, for nitrogen blowing dry operation of the germanium ingot 200.

[0038] In the germanium ingot placing rack 100 according to the present disclosure, by the arrangement of the first low support bar 131, the second low support bar 132, and the high support bar 121, the second low support bar 132 and the high support bar 121 support the bottom surface 200a of the germanium ingot 200, and the first low support bar 131 abuts against the end surface 200b of the germanium ingot 200, so that the germanium ingot 200 is supported and positioned on the first low support bar 131, the second low support bar 132, and the high support bar 121 in an inclined manner relative to the bottom plate 11, for nitrogen blowing dry operation of the germanium ingot 200, which avoids the posture change operation of the hand-held operation in the background art, and improves the operation efficiency of the nitrogen blowing dry of the germanium ingot 200.

[0039] In addition, since the germanium ingot 200 is supported and positioned on the first low support bar 131, the second low support bar 132, and the high support bar 121 in an inclined manner, there is no posture change of the hand holding the germanium ingot in the background art, which avoids the phenomenon of backflow of residual water under the impact of nitrogen, and only one-way nitrogen blowing dry from the high support bar 121 side to the second low support bar 132 side is needed, which eliminates the residual water on the germanium ingot.

[0040] In addition, during nitrogen blowing dry, since only one-way nitrogen blowing dry from the high support bar 121 side to the second low support bar 132 side is needed, the entire germanium ingot can be blown dry without dead angle from the high support bar 121 side to the second low support bar 132 side.

[0041] In order to increase the inclination angle of the germanium ingot 200 positioned on the first low support rod 131, the second low support rod 132 and the high support rod 121, in an example, the first low support rod 131 is lower than the high support rod 121 in the up-down direction D3.

[0042] In an example, the first low support rod 131, the second low support rod 132 and the high support rod 121 are all round rods. In this way, the contact between the first low support rod 131 and the end surface 200b of the germanium ingot 200 is a line contact, and the contact between the second low support rod 132 and the high support rod 121 and the bottom surface 200a of the germanium ingot 200 is also a line contact, so that the drying is simple, effective and fast for the line contact part when the nitrogen gas is blown dry.

[0043] As shown in Figure 1 and Figure 2 , in an example, the first low support rod 131, the second low support rod 132 and the high support rod 121 all extend along the front-rear direction D1.

[0044] In order to improve the work efficiency, as shown in Figure 1 and Figure 2 , in an example, the first low support rod 131, the second low support rod 132 and the high support rod 121 are all provided with a plurality of interval flanges F which are spaced apart along the length and protrude radially outward, and the part between any two adjacent interval flanges F of the first low support rod 131, the second low support rod 132 and the high support rod 121 is used to suspend and support a corresponding germanium ingot 200 on the first low support rod 131, the second low support rod 132 and the high support rod 121 in an inclined manner relative to the bottom plate 11. In this way, a plurality of germanium ingots 200 can be placed on the first low support rod 131, the second low support rod 132 and the high support rod 121 at the same time, and the nitrogen gas drying operation is performed in sequence.

[0045] As shown in Figure 1 and Figure 2 , in an example, the high rod assembly 12 further includes a high front support column 122 and a high rear support column 123.
