Description

Technical Field

[0001] This utility model relates to the field of quartz blowtorch technology, and in particular to a blowtorch housing protection device. Background Technology

[0002] Chemical vapor deposition (CVD) is a widely used technology in materials synthesis and processing. The process involves using a gas as a precursor, where the gaseous phase reacts and interacts with a solid substrate, depositing a thin layer on the substrate surface to achieve material preparation or surface finishing. CVD is also a crucial method for manufacturing quartz glass. 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-containing compounds in the burner's (quartz torch) feed tube to produce silica particles. These silica particles are directly deposited onto a base rod to form a quartz glass dome. During the deposition of the quartz glass dome, the high-temperature molten quartz glass dome is forced by centrifugal force and gravity to gradually diffuse from the center towards the edges, growing and forming a larger diameter quartz glass dome.

[0003] In the production of quartz glass ingots, the burner (quartz torch) is installed at the pre-drilled hole at the top of the reactor. The torch nozzle is inside the reactor, and the torch tail is inside the upper furnace, connected to the gas supply pipe. The production cycle of quartz ingots is relatively long, generally around 20-30 days. The burners used in production are generally made of quartz. The torch head enters the furnace about 10cm deep, where SiCl4 and hydrogen and oxygen undergo a combustion reaction at the torch nozzle. However, residual dust accumulates on the torch shell during production. As production time increases, this dust accumulates to 2-3cm. At high temperatures, the surface of the torch shell crystallizes and becomes brittle. During production, the torch shell is prone to brittle breakage and falling off. Furthermore, the large dust particles that fall off can easily impact and damage the torch shell, forcing production to be terminated prematurely, affecting production capacity. If production is completed normally, a new torch must be replaced for the next production run, impacting production costs and efficiency.

[0004] Therefore, a protective device for the blowtorch housing is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a protective device for a blowtorch housing to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a blowtorch housing protection device, comprising a quartz blowtorch and a pipe fixedly connected to the bottom of the quartz blowtorch, wherein the quartz blowtorch is provided with a reaction section for installation into a reaction vessel; the quartz blowtorch is provided with a protective component for protecting the reaction section, the protective component including a quartz cover provided on the reaction section, the quartz cover being used for dust prevention and protection of the quartz blowtorch, the quartz cover having a fixing groove, a ball fixedly connected to the quartz blowtorch, the quartz blowtorch having a movable ring, and the movable ring having a rotating plate for preventing burns during the removal of the quartz cover.

[0007] Preferably, the quartz cover is fitted onto the reaction section, and the quartz cover is adapted to the reaction section, and the quartz cover and the reaction section are at the same height.

[0008] Preferably, the fixing groove includes a vertical groove and a horizontal groove, and the vertical groove and the horizontal groove are connected to each other. The fixing groove cooperates with the ball to fix the quartz cover.

[0009] Preferably, two rubber blocks are fixedly connected in the transverse groove, and the distance between the two rubber blocks is less than the diameter of the ball. The rubber blocks are provided with arc grooves that are adapted to the ball, and the ends of the rubber blocks are provided with bevels.

[0010] Preferably, the quartz torch is fixedly connected to a bottom ring, and the movable ring is rotatably connected to the bottom ring, and the rotating plate is rotatably connected to the movable ring.

[0011] Preferably, a bonding plate adapted to the quartz cover is fixedly connected to the rotating plate, and a protrusion that can be inserted into the vertical groove is fixedly connected to the bonding plate.

[0012] Preferably, the bonding plate, the rotating plate, and the quartz torch are all provided with anti-scalding cotton, and the movable ring is provided with a blocking part.

[0013] The beneficial effects of this utility model are:

[0014] This invention incorporates a protective component that allows the quartz cover to prevent dust accumulation on the quartz torch's casing during the reaction process. This eliminates the need for additional cleaning by personnel during subsequent processes. It also prevents larger dust particles from impacting and damaging the casing and provides additional mechanical support, especially in brittle areas, reducing the risk of breakage. After production, the quartz cover can be removed, allowing the torch to be reused and avoiding the need for replacement due to torch damage, which would impact production efficiency.

[0015] The design of the ball and the fixing groove facilitates the installation of the quartz cover onto the quartz torch. During the installation process, after the ball enters the vertical groove, rotating the quartz cover allows the ball to enter the horizontal groove, thus fixing the quartz cover onto the torch and maintaining its stability during the reaction. The rotating plate, through the bonding plate and the protrusion, rotates the quartz cover, causing the cylinder to disengage from the fixing groove. This not only allows the quartz cover to be removed and replaced but also prevents burns. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0025] like Figures 1 to 5 As shown, a specific embodiment of this utility model provides a torch housing protection device, including a quartz torch 1 and a pipe 2 fixedly connected to the bottom of the quartz torch 1. The quartz torch 1 is provided with a reaction section 3 that enters the reaction vessel. The quartz torch 1 is provided with a protective component for protecting the reaction section 3. By setting the protective component, the reaction section 3 entering the reaction vessel can be protected, preventing dust particles generated during the reaction from accumulating on the reaction section 3. Therefore, it is not necessary to manually clean the dust on the reaction section 3 after the reaction is completed, reducing the workload. At the same time, it can protect the reaction section 3 from the impact of large dust particles during such a long production cycle, preventing damage to the brittle torch housing. The protective component includes a quartz cover 4 set on the reaction section 3. The quartz cover 4 is used for dust prevention and protection of the quartz torch 1. The quartz cover 4 has a fixing groove. A ball 5 is fixedly connected to the quartz torch 1. The quartz torch 1 is provided with a movable ring 6. The movable ring 6 is provided with a rotating plate 7 for preventing burns during the removal of the quartz cover 4.

[0026] like Figures 1 to 2 As shown, specifically, the quartz cover 4 is fitted onto the reaction section 3, and the quartz cover 4 is compatible with the reaction section 3. The quartz cover 4 and the reaction section 3 are at the same height. The quartz cover 4 is fitted onto the reaction section 3, and its height is the same as that of the reaction section 3, so it follows the reaction section 3 into the reactor. In the reactor, it provides dust protection for the reaction section 3, thereby avoiding the accumulation and damage of dust particles, that is, it provides dust protection for the quartz torch 1. At the same time, the quartz cover 4 can provide additional mechanical support for the shell of the quartz torch 1, especially in the areas where the shell becomes brittle, thereby reducing the risk of breakage. After production is completed, the quartz cover 4 can be disassembled, and the torch can be reused, avoiding the situation where the quartz torch 1 is damaged and needs to be replaced, which would affect production efficiency.

[0027] like Figures 1 to 3As shown, specifically, the fixing groove includes a vertical groove 8 and a horizontal groove 9, and the vertical groove 8 and the horizontal groove 9 are connected. The fixing groove cooperates with the ball 5 to fix the quartz cover 4. Before using the quartz torch 1 for reaction, the quartz cover 4 needs to be installed on the quartz torch 1, as shown. Figure 2 As shown, the quartz cover 4 is gradually moved downwards, gradually fitting onto the quartz torch 1. During the downward installation process, the bead 5 on the quartz torch 1 gradually enters the vertical groove 8 on the quartz cover 4. When the quartz cover 4 can no longer move downwards after the bead 5 enters the vertical groove 8, the quartz cover 4 is rotated so that the bead 5 gradually enters the horizontal groove 9. Two rubber blocks 10 are fixedly connected in the horizontal groove 9, and the distance between the two rubber blocks 10 is less than the diameter of the bead 5. The rubber blocks 10 are provided with arc grooves 11 that are adapted to the bead 5, and the ends of the rubber blocks 10 are provided with inclined surfaces 12. During the process of the bead 5 gradually entering the horizontal groove 9, guided by the inclined surfaces 12, the bead 5... Gradually, the ball 5 moves between the two rubber blocks 10. Since the distance between the two rubber blocks 10 is less than the diameter of the ball 5, the ball 5 causes the rubber blocks 10 to deform under pressure. When the ball 5 moves into the arc groove 11, the deformation of the rubber blocks 10 is restored. This makes it difficult for the ball 5 to pass through the rubber blocks 10 and enter the vertical groove 8 without being subjected to a large force of rotation. At this time, the ball 5 is engaged in the arc groove 11 to maintain the stability of the quartz cover 4 on the quartz torch 1. That is, the quartz cover 4 is limited and fixed on the quartz torch 1, which makes it easy for the quartz cover 4 to maintain stability in the reactor, not to shake, and not to fall off the quartz torch 1.

[0028] like Figures 3 to 5 As shown, specifically, a base ring 13 is fixedly connected to the quartz torch 1, and a movable ring 6 is rotatably connected to the base ring 13. A rotating plate 7 is rotatably connected to the movable ring 6. A fitting plate 14 adapted to the quartz cover 4 is fixedly connected to the rotating plate 7, and a protrusion 15 that can be inserted into the vertical slot 8 is fixedly connected to the fitting plate 14. When production is completed or the quartz cover 4 needs to be removed and replaced, such as Figure 5As shown, since the movable ring 6 is rotatably connected to the bottom ring 13, the movable ring 6 can be rotated to drive the rotating plate 7 to rotate, thereby adjusting the position of the rotating plate 7 so that the position of the rotating plate 7 is in the same vertical direction as the vertical groove 8. Rotating the rotating plate 7 causes it to flip upward, thereby making the bonding plate 14 tightly adhere to the outer wall of the quartz cover 4, and the protrusion 15 enters the vertical groove 8. Subsequently, rotating the rotating plate 7 drives the quartz cover 4 to rotate on the reaction section 3 through the protrusion 15, thereby making the circular arc groove 11 in the circular arc groove 11 rotate. The bead 5 detaches from the two rubber blocks 10 and enters the vertical groove 8. Then, the rotating plate 7 flips downward, causing the bonding plate 14 and the protrusion 15 to detach from the quartz cover 4. The operator uses a frame or other tools to lift the quartz cover 4 and move it upward to separate it from the quartz torch 1. The movable ring 6 is provided with a blocking part 17. The blocking part 17 is set so that when the rotating plate 7 flips downward, it blocks the rotating plate 7, preventing the protrusion 15 and the bonding plate 14 on the rotating plate 7 from colliding with the quartz torch 1 and causing it to be damaged.

[0029] The reason for using the above process to separate the quartz cover 4 from the quartz torch 1 is that during the use of the quartz torch 1, it is burned in the reaction vessel, which generates a high temperature. As a result, both the quartz torch 1 and the quartz cover 4 become hot. When separating the two, without the support of anti-scalding equipment such as high-temperature protective gloves, touching them with bare hands will cause burns. Furthermore, disassembling and separating them while wearing high-temperature protective gloves will reduce hand dexterity, make operation inconvenient, and lead to errors. Waiting for them to cool down naturally will waste time and affect the subsequent work process. Therefore, using the above-mentioned device for disassembly and separation is simple and convenient, and prevents burns. Anti-scalding cotton 16 is provided on the bonding plate 14, the rotating plate 7, and the quartz torch 1. The anti-scalding cotton 16 ensures that the workers' hands will not be burned due to heat conduction when they come into contact with it.

[0031] This utility model is intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
