Description

Technical Field

[0001] This invention belongs to the field of gallium antimonide production technology, specifically a high-purity gallium antimonide polycrystalline synthesis production equipment. Background Technology

[0002] Gallium antimonide is a group III-V compound semiconductor material. Its research is far less in-depth than that of other semiconductor materials (such as GaAs, InP, etc.). However, in recent years, this material has attracted more and more attention. This is mainly due to the development of optical fiber communication technology and the potential demand for new devices. In order to reduce transmission loss in optical communication, longer wavelengths of light are always used as much as possible. The earliest use was 0.8μm wavelength light, and then 1.55μm wavelength light.

[0003] In the production technology based on high-purity gallium antimonide polycrystalline synthesis, antimony and gallium raw materials need to be uniformly stirred in a graphite crucible and given appropriate reaction conditions. The reaction is carried out by heating elemental antimony and elemental gallium in an open graphite crucible.

[0004] Currently, most graphite crucibles have their bottoms mounted on rotating parts at the bottom, and the method of tightening them with fasteners is very complicated during assembly and disassembly. At the same time, it is easy to cause safety hazards due to the high temperature environment. In addition, during the reaction process, the graphite crucible is usually driven to rotate by a rotating mechanism to improve the synthesis production efficiency. The continuous rotation in one direction causes some raw materials to stick to the graphite crucible. The raw materials always move in one direction, resulting in poor flowability of the raw materials in the graphite crucible. This leads to uneven heating of the raw materials in the middle of the graphite crucible and poor mixing reaction effect, which is not conducive to the efficient and high-quality production of high-purity gallium antimonide polycrystalline materials. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] To overcome the aforementioned shortcomings of existing technologies, this invention provides a high-purity gallium antimonide polycrystalline synthesis production equipment. This solves the problem that the bottom of most graphite crucibles is placed on a rotating component at the bottom, requiring fasteners for tightening, which is cumbersome during assembly and disassembly and poses safety hazards due to high temperatures. Furthermore, current methods typically use a rotating mechanism to drive the graphite crucible to improve synthesis efficiency. However, continuous unidirectional rotation causes some raw materials to adhere tightly to the graphite crucible, resulting in poor material flow within the crucible. This leads to uneven heating of the material in the center of the crucible and poor mixing reaction, hindering the efficient and high-quality production of high-purity gallium antimonide polycrystalline materials.

[0019] (III) Beneficial Effects

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] 1. In this invention, by setting up a heating furnace, a graphite crucible, a support assembly, an annular groove, a connecting shaft, a bevel gear, and a bevel gear, during the production of high-purity gallium antimonide polycrystalline materials, the graphite crucible is placed on a pallet, and a limiting block is inserted into the limiting groove. Elemental antimony and elemental gallium are heated and reacted within the open graphite crucible. A motor is controlled to operate, and the motor's output shaft drives the bevel gear to rotate. Since one-third of the bevel gear is covered by its teeth, during the meshing process between the bevel gear and the lower bevel gear, the bevel gear drives the graphite crucible to rotate via the connecting shaft and the support assembly. The bevel gear continues to rotate, disengaging from the lower bevel gear and meshing with the upper bevel gear. The upper bevel gear then drives the graphite crucible to rotate in the opposite direction via the connecting shaft and the support assembly. This process repeats continuously, causing the graphite crucible to oscillate continuously, allowing the internal raw materials to be fully mixed under the reverse thrust. This improves the fluidity of the raw materials within the graphite crucible, resulting in uniform heating of the raw materials and enhanced mixing reaction efficiency. This is beneficial for the efficient and high-quality production of high-purity gallium antimonide polycrystalline materials.

[0022] 2. In this invention, by setting up a column, a slot, a rod, a spring, a sleeve, a limiting block, a limiting cylinder, and a retaining ring, when limiting the graphite crucible, the retaining ring at the bottom of the graphite crucible is fitted into the limiting cylinder. Since the right end of the rod is an inclined end face, the rod automatically retracts after being pressed until the limiting block is completely inserted into the limiting groove. The spring supports the rod to be inserted into the slot in the retaining ring, effectively limiting the graphite crucible. Similarly, when removing the graphite crucible, since the right end of the rod is an inclined end face, after lifting the graphite crucible, the slot squeezes the rod to retract it, and the limiting block disengages from the limiting groove, allowing the graphite crucible to be removed. Therefore, the disassembly and assembly of the graphite crucible is very convenient, without the need for operation inside the heating furnace, avoiding safety hazards caused by the high-temperature environment.

[0023] 3. In this invention, by setting up a ring, annular groove, pulley, reinforcing rod, cavity, and heating coil, the graphite crucible is supported by multiple reinforcing rods and a ring when supported by a support plate. The load-bearing capacity of the connecting shaft is reduced by increasing the force-bearing area. Furthermore, the pulley rotates in the annular groove and supports the annular groove, making the rotation of the graphite crucible more stable, improving the working stability of the production equipment, and reducing malfunctions. Through the cooperation between the cavity and the heating coil, the heating furnace effectively plays a role in noise reduction and heat preservation, which is beneficial to the production of high-purity gallium antimonide polycrystalline synthesis.

[0031] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0032] like Figure 1-6 As shown, the present invention provides a technical solution: a high-purity gallium antimonide polycrystalline synthesis production equipment, including a base plate 1, the upper surface of the base plate 1 being fixedly connected to the lower surface of a support plate 2, supports 3 being provided on both sides of the base plate 1 and the support plate 2, a rope coil 4 being provided on the top of the supports 3, a heating furnace 5 being provided between the two supports 3, the lower surface of the heating furnace 5 being fixedly connected to the upper surface of the support plate 2, a graphite crucible 6 being provided inside the heating furnace 5, a retaining ring 13 being connected to the lower surface of the graphite crucible 6, a limiting block 14 being provided in the middle of the retaining ring 13, and the upper surface of the limiting block 14 being fixedly connected to the lower surface of the graphite crucible 6.

[0033] The retaining ring 13 is fitted onto the outer wall of the limiting cylinder 8. The lower surface of the limiting cylinder 8 is fixedly connected to the upper surface of the support component 7. The bottom of the support component 7 is fixedly connected to the top of the connecting shaft 17. The connecting shaft 17 passes through the support plate 2 and is fixedly connected to the top of the adjusting component 18. The bottom end of the adjusting component 18 is set on the upper surface of the base plate 1 through a bushing. The adjusting component 18 meshes with the bevel gear disk 19. The left side of the bevel gear disk 19 is fixedly connected to the right end of the drive component 20. The lower surface of the drive component 20 is fixedly connected to the upper surface of the base plate 1.

[0034] Specifically, such as Figure 2 , Figure 3 and Figure 6As shown, a column 10 is provided in the middle of the limiting cylinder 8, and a limiting groove 11 is opened at the top of the column 10. The limiting block 14 is engaged in the limiting groove 11. Both the limiting block 14 and the limiting groove 11 are rectangular designs. The inner wall of the heating furnace 5 is provided with several heating coils 22. Through the mutual cooperation between the cavity 23 and the heating coils 22, the heating furnace 5 can effectively play the role of noise reduction and heat preservation, which is beneficial to the production of high-purity gallium antimonide polycrystalline synthesis. The interior of the heating furnace 5 is provided with a cavity 23. The support component 7 includes a ring 71, and the inner wall of the ring 71 is... The support plate 73 is fixedly connected to the outer wall of the support plate 73 by several reinforcing rods 72 and a ring 71. The load-bearing capacity of the connecting shaft 17 is reduced by increasing the force-bearing area. Furthermore, the pulley 74 rotates in the annular groove 21 and supports the annular groove 21, making the graphite crucible 6 more stable when rotating and improving the working stability of the production equipment. The upper surface of the support plate 73 is fixedly connected to the lower surface of the limiting cylinder 8 and the column 10, and the lower surface of the support plate 73 is fixedly connected to the top end of the connecting shaft 17.

[0035] Specifically, such as Figure 4 and Figure 6 As shown, the outer wall of the limiting cylinder 8 has six grooves 9. Two clamping components 12 are engaged with the inner wall of each groove 9. The other end of each clamping component 12 is fixedly connected to the outer wall of the column 10. The outer wall of the clamping component 12 is engaged with the inner wall of the limiting cylinder 8 via a sliding sleeve 125. The clamping component 12 includes a sleeve 121, one end of which is fixedly connected to the outer wall of the column 10. A clamping rod 122 is fitted inside the sleeve 121. By setting the clamping rod 122, and because the right end of the clamping rod 122 is an inclined end face 124, after the graphite crucible 6 is lifted, the clamping groove 15 squeezes the clamping rod 122 to retract it. The limiting block 14 disengages from the limiting groove 11, allowing the graphite crucible 6 to be removed. Therefore, the disassembly and assembly of the graphite crucible 6 is very convenient and does not require operation inside the heating furnace 5. The outer wall of the clamping rod 122 is fitted with... A spring 123 is provided, with its two ends fixedly connected to the opposite surfaces of the sleeve 121 and the sliding sleeve 125, respectively. Through the cooperation between the locking rod 122 and the spring 123, the retaining ring 13 at the bottom of the graphite crucible 6 is fitted into the limiting cylinder 8. Since the right end of the locking rod 122 is an inclined end face 124, the locking rod 122 automatically retracts after being pressed until the limiting block 14 is completely inserted into the limiting groove 11. With the support of the spring 123, the locking rod 122 is inserted into the retaining groove 15 in the retaining ring 13, effectively realizing the limiting work of the graphite crucible 6. The upper and lower sides of the right end of the locking rod 122 are set as inclined end faces 124, and one end of the locking rod 122 is inserted into the retaining groove 15. The retaining groove 15 is opened on the inner wall of the retaining ring 13. The lower surface of the graphite crucible 6 is provided with four support feet 16.

[0036] Specifically, such as Figure 1 and Figure 3As shown, the adjusting assembly 18 includes a rotating shaft 181. The top end of the rotating shaft 181 is fixedly connected to the bottom end of the connecting shaft 17. The bottom end of the rotating shaft 181 is engaged with the upper surface of the base plate 1 via a bushing. Two bevel gears 182 are engaged with the outer wall of the rotating shaft 181. Both bevel gears 182 mesh with a bevel gear disk 19. The bevel gear disk 19 is configured such that one-third of the disk is covered by several teeth. Through the mutual cooperation between the bevel gear disk 19 and the bevel gears 182, the bevel gear 182, through the connecting shaft 17 and the support assembly 7, drives the graphite crucible 6 to rotate. The bevel gear disk 19 continues to rotate, causing it to disengage from the lower bevel gear 182. The upper bevel gear 182 meshes with the upper bevel gear 182, causing the upper bevel gear 182 to drive the graphite crucible 6 to rotate in the opposite direction through the connecting shaft 17 and the support assembly 7. This process repeats, and the graphite crucible 6 continues to swing, causing the raw materials inside to be fully mixed under the action of the reverse thrust, improving the fluidity of the raw materials in the graphite crucible 6, thereby making the raw materials heat evenly. The drive assembly 20 includes a motor 201. The lower surface of the motor 201 body is fixedly connected to the upper surface of the fixing block 202. The lower surface of the fixing block 202 is fixedly connected to the upper surface of the base plate 1. The output shaft of the motor 201 is fixedly connected to the left side of the bevel gear disk 19. An inspection door 24 is provided in front of the motor 201. The inspection door 24 is snapped between the base plate 1 and the support plate 2.

[0037] The working principle of this invention is as follows:

[0038] When limiting the graphite crucible 6, the retaining ring 13 at the bottom of the graphite crucible 6 is fitted into the limiting cylinder 8. Since the right end of the retaining rod 122 is an inclined end face 124, the retaining rod 122 automatically retracts after being pressed until the limiting block 14 is completely inserted into the limiting groove 11. Supported by the spring 123, the retaining rod 122 is inserted into the retaining groove 15 in the retaining ring 13, effectively realizing the limiting work of the graphite crucible 6. Elemental antimony and elemental gallium are heated and reacted in the open graphite crucible 6, causing the heating coil 22 on the heating furnace 5 to work. The raw material synthesis temperature is set at 710-720℃, and the motor 201 is controlled to work. The output shaft of motor 201 drives the bevel gear disk 19 to rotate. Since one-third of the bevel gear disk 19 is covered by the teeth, during the process of bevel gear disk 19 meshing with the lower bevel gear 182, the bevel gear 182 drives the graphite crucible 6 to rotate through the connecting shaft 17 and the support assembly 7. The bevel gear disk 19 continues to rotate, causing it to disengage from the meshing state with the lower bevel gear 182 and mesh with the upper bevel gear 182. This causes the upper bevel gear 182 to drive the graphite crucible 6 to rotate in the opposite direction through the connecting shaft 17 and the support assembly 7. This process is repeated, and the graphite crucible 6 continues to swing, allowing the raw materials inside to be fully mixed under the action of the reverse thrust.

[0039] In summary:

[0040] By setting up a heating furnace 5, a graphite crucible 6, a support assembly 7, an annular groove 21, a connecting shaft 17, a bevel gear 19, and a bevel gear 182, during the production of high-purity gallium antimonide polycrystalline synthesis, the graphite crucible 6 is placed on a support plate 73, and the limiting block 14 is engaged with the limiting groove 11. Elemental antimony and elemental gallium are heated and reacted within the open graphite crucible 6, while the motor 201 is controlled to operate. The output shaft of the motor 201 drives the bevel gear 19 to rotate. Since one-third of the bevel gear 19 is covered by teeth, during the meshing process between the bevel gear 19 and the bevel gear 182 below, the bevel gear 182... 2. The graphite crucible 6 is rotated by the connecting shaft 17 and the support assembly 7. The bevel gear disk 19 continues to rotate, causing it to disengage from the lower bevel gear 182 and mesh with the upper bevel gear 182. The upper bevel gear 182 drives the graphite crucible 6 to rotate in the opposite direction through the connecting shaft 17 and the support assembly 7. This process is repeated, and the graphite crucible 6 continues to swing, causing the raw materials inside to be fully mixed under the action of the reverse thrust. This improves the fluidity of the raw materials in the graphite crucible 6, thereby making the raw materials heat evenly and improving the mixing reaction effect. This is beneficial to the efficient and high-quality production of high-purity gallium antimonide polycrystalline materials.

[0041] By configuring a column 10, a slot 15, a locking rod 122, a spring 123, a sleeve 121, a limiting block 14, a limiting cylinder 8, and a retaining ring 13, when limiting the graphite crucible 6, the retaining ring 13 at the bottom of the graphite crucible 6 is fitted into the limiting cylinder 8. Since the right end of the locking rod 122 is an inclined end face 124, the locking rod 122 automatically retracts after being pressed until the limiting block 14 is completely inserted into the limiting slot 11. The locking rod 122 is supported by the spring 123. The graphite crucible 6 is effectively limited by the slot 15 inside the retaining ring 13. Similarly, when removing the graphite crucible 6, because the right end of the retaining rod 122 is an inclined end face 124, after the graphite crucible 6 is lifted, the slot 15 squeezes the retaining rod 122 to retract it, and the limiting block 14 disengages from the limiting groove 11, so the graphite crucible 6 can be removed. Therefore, the disassembly and assembly of the graphite crucible 6 is very convenient and does not need to be carried out in the heating furnace 5, avoiding safety hazards caused by the high temperature environment.

[0042] By setting up annular ring 71, annular groove 21, pulley 74, reinforcing rod 72, cavity 23, and heating coil 22, the graphite crucible 6 is supported by the support plate 73. Multiple reinforcing rods 72 and annular ring 71 support it, thereby increasing the force-bearing area and reducing the load-bearing capacity of the connecting shaft 17. Furthermore, the pulley 74 rotates within the annular groove 21 and supports the annular groove 21, making the rotation of the graphite crucible 6 more stable, improving the working stability of the production equipment, and reducing malfunctions. Through the cooperation between cavity 23 and heating coil 22, the heating furnace 5 effectively plays a role in noise reduction and heat preservation, which is beneficial to the production of high-purity gallium antimonide polycrystalline synthesis.
