Description

Technical Field

[0001] This utility model relates to the field of quartz glass ingot preparation technology, and in particular to a deposition furnace for preparing quartz glass ingots. Background Technology

[0002] The main methods for melting synthetic quartz glass ingots are horizontal deposition furnace chemical vapor deposition (CVD) and vertical deposition furnace CVD. Horizontal deposition furnace CVD is gradually being replaced by vertical deposition furnace CVD because it cannot produce large-size, heavy quartz glass ingots, and suffers from low furnace temperature, high energy consumption, and low efficiency. In existing vertical deposition furnace CVD technology, hydrogen and oxygen are burned in a burner to produce water vapor, which then reacts with gaseous silicon tetrachloride in the burner feed pipe to produce silica particles. These silica particles are directly deposited onto a base rod to form a quartz glass ingot. During the deposition process, the centrifugal force and gravity of the high-temperature molten quartz glass ingot force the central quartz glass to gradually diffuse towards the edges, growing and forming a larger diameter quartz glass ingot.

[0003] Existing deposition furnaces require capping, which involves tightening multiple bolts one by one, increasing operational complexity and time costs. Since each bolt needs to be operated individually, the time required for the entire capping process increases significantly. Therefore, there is a need to provide a deposition furnace that can be capped quickly to improve the production efficiency of quartz glass pellets. Utility Model Content

[0004] The purpose of this invention is to provide a deposition furnace for preparing quartz glass ingots, in order to solve the problem mentioned in the background art, that existing deposition furnaces require sealing, and during the sealing process, multiple bolts need to be tightened one by one, which increases the complexity and time cost of operation. Since each bolt needs to be operated individually, the time required for the entire sealing process will increase significantly.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a deposition furnace for preparing quartz glass ingots, comprising:

[0007] Deposition furnace;

[0008] The sealing assembly includes a sealing cap, fixing posts, fixing grooves, fixing blocks, square grooves, and fixing holes. The sealing cap is installed on the top surface of the deposition furnace. Five fixing posts are fixed on the lower surface of the sealing cap. The fixing grooves are opened at the lower ends of the fixing posts. The fixing blocks are fixed on the upper part of the outer surface of the deposition furnace. Square grooves are opened on both sides of the fixing blocks. Fixing holes are opened on the top surface of the fixing blocks, and the fixing posts extend into the fixing holes.

[0009] Furthermore, a fixing frame is fixed in the middle of the outer surface of the deposition furnace, a first connecting shaft is fixed on one side of the fixing frame, a second connecting shaft is fixed on the other side of the fixing frame, and a motor is fixed at one end of the first connecting shaft.

[0010] Furthermore, a first bracket is fixed to the lower surface of the motor, and a second bracket is fixed to the outer surface of the second connecting shaft.

[0011] Furthermore, connecting frames are fixed on both sides of the fixing block, springs are fixed inside the connecting frames, and a locking post is fixed at one end of the spring. The end of the locking post extends into the fixing groove, and an unlocking groove is opened on the top surface of the connecting frame.

[0012] Furthermore, it also includes a lubrication assembly, which includes an oil reservoir, a rotating cap, and a connecting pipe. The oil reservoir is fixed to the top surface of the second bracket, the rotating cap is threaded onto the top surface of the oil reservoir, and the connecting pipe is fixed to the lower end of one side of the oil reservoir.

[0013] Furthermore, a lower connecting frame is fixed to the lower end of the connecting pipe, and the lower end of the lower connecting frame is arc-shaped, and the lower connecting frame is in contact with the outer surface of the second connecting shaft.

[0014] Furthermore, a rotating groove is provided on the lower surface of the lower frame, and a rotating bead is rotatably installed inside the rotating groove.

[0015] Compared with existing technologies, the advantages of this utility model are:

[0016] I. This utility model, through the setting of a deposition furnace and a sealing cap assembly, firstly, the fixing post is inserted into the fixing hole when the sealing cap is installed on the deposition furnace. Then, the spring is compressed through the unlocking groove. The compression of the spring synchronously drives the fixing post to move outward. When the fixing groove and the fixing post are aligned, the spring will quickly restore its deformation under the action of the spring blocking force. The spring drives the fixing post to move inward, so that the fixing post will be inserted into the fixing groove, thus fixing the sealing cap on the deposition furnace. It can quickly fix the sealing cap. Through the cooperation of the fixing post and the fixing groove, it is only necessary to insert the fixing post into the fixing hole, and then use the interaction between the spring and the unlocking groove to quickly complete the fixing of the sealing cap, which greatly simplifies the tedious process of tightening bolts one by one in the traditional way.

[0017] II. Based on the first beneficial effect, the deposition furnace and lubrication components, when in use, drive the first connecting shaft to rotate via a motor. The first connecting shaft synchronously drives the fixed frame to rotate, which in turn drives the deposition furnace to rotate. The rotation of the fixed frame synchronously drives the second connecting shaft to rotate, which in turn drives the rotating ball to rotate. The rotating ball draws the lubricating oil from inside the lower connecting frame down, and the connecting pipe draws the lubricating oil from the oil storage tank. The lubricating oil flows onto the second connecting shaft, ensuring that the lubricating oil is evenly and continuously distributed on the parts that need lubrication. This can significantly reduce the wear between the moving parts in the deposition furnace and extend the service life of the equipment. Attached Figure Description

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0031] Please see Figures 1 to 4 As shown, this embodiment is a deposition furnace for preparing quartz glass ingots, comprising:

[0032] A deposition furnace 11 has a fixed frame 12 fixed in the middle of its outer surface. A first connecting shaft 13 is fixed on one side of the fixed frame 12, and a second connecting shaft 131 is fixed on the other side of the fixed frame 12. A motor 14 is fixed at one end of the first connecting shaft 13.

[0033] The deposition furnace 11 serves as the main container of the entire equipment, used to house and carry out the deposition process. The fixed frame 12 is the main support and fixing structure, ensuring the stability and reliability of the deposition furnace 11 during operation. One end of the first connecting shaft 13 is connected to the motor 14, which serves as a power source and transmits power to the deposition furnace 11 through the first connecting shaft 13.

[0034] The sealing assembly includes a sealing cap 21, fixing posts 22, fixing grooves 23, fixing blocks 24, square grooves 241, and fixing holes 25. The sealing cap 21 is installed on the top surface of the deposition furnace 11. Five fixing posts 22 are fixed on the lower surface of the sealing cap 21. The fixing grooves 23 are opened at the lower ends of the fixing posts 22. The fixing blocks 24 are fixed on the upper part of the outer surface of the deposition furnace 11. The square grooves 241 are opened on both sides of the fixing blocks 24. The fixing holes 25 are opened on the top surface of the fixing blocks 24, and the fixing posts 22 extend into the fixing holes 25.

[0035] The sealing cover 21 is installed on the top surface of the deposition furnace 11 to seal the top opening of the deposition furnace 11 and prevent material leakage and the entry of external impurities during the deposition process. During the sealing process, the fixing post 22 is inserted into the fixing hole 25 on the fixing block 24 and is quickly fixed by the action of the spring 27 and the locking post 28. The square grooves 241 on both sides of the fixing block 24 are used to install the connecting frame 26, while the fixing hole 25 on the top surface is used to cooperate with the fixing post 22 to fix the sealing cover 21.

[0036] A first bracket 15 is fixed to the lower surface of the motor 14, and a second bracket 16 is fixed to the outer surface of the second connecting shaft 131.

[0037] A connecting frame 26 is fixed on both sides of the fixing block 24. A spring 27 is fixed inside the connecting frame 26, and a locking post 28 is fixed at one end of the spring 27. The end of the locking post 28 extends into the fixing groove 23. An unlocking groove 29 is opened on the top surface of the connecting frame 26.

[0038] During the sealing process, the locking post 28 moves rapidly inward under the elastic force of the spring 27 and locks into the fixing groove 23, thereby quickly fixing the sealing cap 21.

[0039] Working principle:

[0040] When installing the sealing cap 21 on the deposition furnace 11, firstly, the fixing post 22 is inserted into the fixing hole 25. Then, the spring 27 is compressed through the unlocking groove 29. The compression of the spring 27 synchronously drives the locking post 28 to move outward. When the fixing groove 23 is aligned with the locking post 28, the spring 27 will quickly recover its deformation under the blocking force of the spring 27. The spring 27 drives the locking post 28 to move inward, so that the locking post 28 will be inserted into the fixing groove 23, thus fixing the sealing cap 21 on the deposition furnace 11. This can quickly fix the sealing cap 21.

[0041] In this step, by cooperating with the locking post 28 and the fixing groove 23, the fixing post 22 is simply inserted into the fixing hole 25, and then the fixing of the sealing cover 21 can be quickly completed by the interaction of the spring 27 and the unlocking groove 29, which greatly simplifies the tedious process of tightening the traditional bolts one by one.

[0042] Please see Figures 1 to 4 As shown; this embodiment, based on the above embodiment, further includes:

[0043] The lubrication assembly includes an oil reservoir 31, a rotating cover 32, and a connecting pipe 33. The oil reservoir 31 is fixed to the top surface of the second bracket 16, the rotating cover 32 is threaded onto the top surface of the oil reservoir 31, and the connecting pipe 33 is fixed to the lower end of one side of the oil reservoir 31.

[0044] The lower end of the connecting pipe 33 is fixed with a lower connecting frame 34, and the lower end of the lower connecting frame 34 is arc-shaped, and the lower connecting frame 34 is in contact with the outer surface of the second connecting shaft 131.

[0045] A rotating groove 35 is provided on the lower surface of the lower frame 34, and a rotating bead 36 is rotatably installed inside the rotating groove 35.

[0046] The oil storage tank 31, as the main part of the lubrication assembly, is used to store lubricating oil and provide a stable oil source for the entire lubrication system. The rotating cover 32 is used to seal the oil storage tank 31 to prevent lubricating oil leakage and the entry of external impurities. The connecting pipe 33 is used to transport the lubricating oil in the oil storage tank 31 to the lower connecting frame 34. The lower connecting frame 34 is used to receive the lubricating oil transported from the connecting pipe 33. The rotating bead 36 can rotate together with the second connecting shaft 131 when it rotates. The presence of the rotating bead 36 helps to distribute the lubricating oil more evenly on the outer surface of the second connecting shaft 131.

[0047] Working principle:

[0048] When the deposition furnace 11 is in use, the motor 14 drives the first connecting shaft 13 to rotate, the first connecting shaft 13 synchronously drives the fixed frame 12 to rotate, the fixed frame 12 synchronously drives the deposition furnace 11 to rotate, the fixed frame 12 synchronously drives the second connecting shaft 131 to rotate, the second connecting shaft 131 rotates and drives the rotating ball 36 to rotate, the rotating ball 36 rotates and draws down the lubricating oil inside the lower connecting frame 34, the connecting pipe 33 draws the lubricating oil down from the oil storage tank 31, and the lubricating oil flows on the second connecting shaft 131;

[0049] This step ensures that the lubricating oil is evenly and continuously distributed in the parts that need lubrication, which can significantly reduce wear between moving parts in the deposition furnace and extend the service life of the equipment.
