Description

Technical Field

[0001] The utility model relates to the technical field of core rod processing, in particular to a core rod polishing and mist elimination device. Background Art

[0002] The core rod is made of high-purity SiCl4 and GeCl4. The loose SiO2 particles are obtained through VAD deposition technology. When melted at high temperature, the loose body becomes a transparent glass preform rod. During the manufacturing process, the surface of the vitrified core rod is prone to scratches, particles and other appearance defects. Therefore, before the OVD deposition, the core rod must first be flame polished to eliminate the core rod stress and surface scratches, particles and other impurities. However, during flame polishing, the dispersed flame band will cause the core rod surface to heat up for a long time, volatile white mist SiO2, and in order to remove the residual SiO2 on the core rod surface, it is necessary to polish again to make the core rod surface colorless and transparent, which increases the polishing time and gas consumption. In addition, in the existing core rod polishing method, the flame torch needs to perform a round trip motion that takes about 1 hour to complete a core rod polishing operation. This polishing method is not only time-consuming, but also has a large gas flow rate in the process of eliminating SiO2 dust.

[0003] At present, the domestic core rod polishing adopts the horizontal rolling lathe to generate high temperature through the hydrogen-oxygen flame. In order to ensure the quality of core rod polishing, the lathe's blowtorch angle, movement speed, and hydrogen-oxygen flow rate will be debugged, and then the flame blowtorch will be used to polish from the starting point to the end point. The purpose of this process is to remove most of the impurities and defects on the surface of the core rod. The hydrogen-oxygen flame sprayed by the blowtorch will cause the flame to diverge when it hits the core rod. Through this divergence phenomenon, the area that the blowtorch has not passed can be preheated, so that the impurities and defects on the surface of the core rod can be more effectively treated; however, the divergent flame belt causes the core rod surface to be heated for a long time, resulting in a large amount of SiO2 volatilization. After this polishing, white mist-like SiO2 dust appears on the surface of the core rod. If the SiO2 dust on the surface is not eliminated, the quality of the core rod will be affected. Therefore, the flame blowtorch will also return from the end point to the starting point, such as Figure 3 As shown, a small flow of hydrogen-oxygen flame is used to eliminate the white mist-like SiO2 dust on the core rod surface. Since the polishing time and gas flow rate determine the consumption of production costs, the production cost of the existing core rod polishing method is relatively high. Utility Model Content

DETAILED DESCRIPTION

[0025] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0026] Reference Figure 1 and 2As shown, the utility model discloses a mandrel polishing and demisting device, comprising: a lathe 1, on which a mobile platform 11 is provided; a mandrel fixture 2, which is arranged on the lathe 1 and is used to clamp and fix the starting point and the end point of the mandrel; a mandrel polishing and demisting device 3, which is arranged on the mobile platform 11; the mandrel polishing and demisting device 3 comprises a torch support 31, a polishing torch 32, a demisting torch 33 and a plurality of gas pipelines 34, the polishing torch 32 and the demisting torch 33 are arranged on the torch support 31, and the torch air inlets of the polishing torch 32 and the demisting torch 33 are respectively connected to the gas pipeline 34. The torch support 31 comprises a support plate 311 and a nozzle fixing seat 312, the support plate 311 is vertically arranged on the mobile platform 11, the nozzle fixing seat 312 is arranged between two support plates 311, and there is a gap between the nozzle fixing seat 312 and the mobile platform 11 for the gas pipeline 34 to pass through.

[0027] The core rod polishing and demisting device based on the above structure utilizes the original moving mode of the lathe 1. By only modifying the polishing and demisting blowtorch device, a low-cost modification method is used to reduce the overall time and gas consumption of the polishing process, thereby effectively reducing the production cost of the polishing process.

[0028] In this embodiment, the polishing torches 32 include three, all of which are arranged at an angle with the horizontal plane of the nozzle fixing seat 312. The mist elimination torches 33 include two, all of which are arranged at an angle with the horizontal plane of the nozzle fixing seat 312.

[0029] Furthermore, an exhaust hood 4 is also provided on the mobile platform 11 , and the exhaust hood 4 is fixed above the mandrel polishing and demisting device 3 through a support 8 .

[0030] Preferably, the exhaust hood 4 comprises a hood body, an air suction cavity is provided in the hood body, the lower end of the hood body is open, and the air suction cavity is connected to the exhaust pipe.

[0031] In addition, a crawler belt 7 is provided on one side of the lathe 1 , and the crawler belt 7 is used to fix the driving gas pipeline 34 .

[0032] In this embodiment, the mobile platform 11 is controlled by a driving mechanism disposed on the lathe 1 to move horizontally along the length direction of the lathe 1. The driving mechanism includes a screw rod 5, a sliding seat 6 and a servo motor, both ends of the screw rod 5 are disposed on the lathe 1 through a fixed seat 9, one end of the screw rod 5 is connected to the output shaft of the servo motor, the sliding seat 6 is threadedly connected to the screw rod 5, and the sliding seat 6 is connected to the mobile platform 11.

[0033] Preferably, the mandrel clamp 2 includes a fixed clamp 21 and an adjustable clamp 22, wherein the fixed clamp 21 is arranged on one side of the lathe 1, and the adjustable clamp 22 is arranged on the other side of the lathe 1, and the adjustable clamp 22 can slide along the lathe 1 to adjust the distance between the adjustable clamp 22 and the fixed clamp 21. The design of the adjustable clamp 22 can meet the clamping requirements of mandrels of different specifications.

[0034] During installation, install the blowtorch bracket 31 on the mobile platform 11 of the lathe 1, fix three polishing blowtorches 32 and two demisting blowtorches 33 on the blowtorch bracket 31 at appropriate angles, and connect the blowtorch air inlet to the gas pipeline 34. In this way, the polishing and demisting device 3 is assembled. When the lathe 1 uses the polishing blowtorch 32 for polishing, it can drive the entire demisting blowtorch 33 to run together.

[0035] When the lathe 1 is polishing, the polishing torch 32 first polishes at a uniform speed from the starting point of the mandrel to the end point. After moving a distance, the torch support 31 is controlled to move to the starting point of the mandrel, and the mist-eliminating torch 33 starts to ignite. Since the polishing torch 32 has just polished this section of the mandrel, the temperature of this section of the mandrel will be very high, and only a smaller flow of hydrogen-oxygen flame is needed to eliminate the SiO2 dust on the surface of the mandrel. When the polishing torch 32 reaches the end of the mandrel, the flame goes out, and then the mist-eliminating torch 33 also reaches the end of the mandrel and extinguishes the flame. The lathe 1 only needs to move from the starting point of the mandrel to the end point to complete the polishing operation.

[0036] like Figure 3 As shown, the data before and after the use of the polishing and mist elimination device 3 are compared. From the data in the figure, it can be seen that the total time of core rod polishing is reduced by more than 30%, and the amount of hydrogen and oxygen used is reduced by about 20%.

[0037] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
