[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0030] In the description of the embodiments of the present invention, it should be understood that terms such as "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside" and "outside" indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the referred device or element must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0031] like Figure 1 and Figure 4 As shown, the present invention proposes a quartz melting processing fireproof cover, which is configured as a fireproof cover arranged at the front of a columnar quartz heat treatment furnace, including a fireproof back plate 1, an axis fixer 2, a rotating shaft 3, a starting cover plate 6 and a rotating cover plate 7, and two groups of axis fixers 2 are provided at the front of the fireproof back plate 1, and the two groups of axis fixers 2 are symmetrically arranged on the upper part of the fireproof back plate 1, and the two groups of axis fixers 2 are provided with a rotating shaft 3 inside.

[0032] In this embodiment, quartz is a mineral resource with very stable physical and chemical properties. High-purity quartz can be obtained after purification. The purification process of high-purity quartz is to first grind the mineral quartz to the required particle size and remove some impurities, and then separate or dissolve the impurities by physical and chemical methods. The entire purification process can be simply summarized as three processes: pretreatment, physical treatment and chemical treatment, specifically using a variety of mineral processing methods such as crushing, grinding, screening, magnetic separation, pickling, chlorination roasting, etc.

[0033] After quartz is processed into high-purity quartz, it will be made into quartz rods for the convenience of subsequent processing. Quartz rods are a multifunctional material that is widely used in various fields, such as:

[0034] Optoelectronics: Quartz rods are used to make optical fiber modulators, optical fiber filters, spectrometers, etc. They can also be used in optical imaging equipment.

[0035] Semiconductor field: Quartz rod is one of the materials used as electrode plug-in, chemical vapor transporter and high-temperature component in the semiconductor manufacturing process;

[0036] Chemical experiment field: Quartz rods can be used in experimental instruments, such as quartz calorimeters, quartz tube high-pressure vessels, quartz reactors, etc., as well as in filtration, separation and sensing;

[0037] Metallurgical industry: Quartz rods are used to make refractory silicon bricks, as well as raw materials for flux and crystalline silicon production;

[0038] Glass industry: Quartz rods are important raw materials for glass manufacturing and are used in the production of various glass products such as flat glass and wired glass;

[0039] Construction industry: Quartz rods can be used as building foundation stones, road filling, railway ballast, and correction materials for silicate cement, etc.

[0040] Grinding industry: Quartzite and quartz sandstone can be used to make grinding materials such as grindstones, oilstones, and sandpaper, while quartz sand is also used in the processing of sawn stone and polished glass.

[0041] Other industries: Quartz can also be used as enamel and ceramic raw materials, as well as in the radio industry, ultrasonic technology and modern defense applications;

[0042] Electric light source field: Quartz tubes and rods include high-purity quartz tubes, UV tubes, transparent tubes, etc., which are used in a variety of lamps in the traditional lighting industry and special light source industry.

[0043] However, depending on the application field, the quartz rod 32 needs to be processed into various shapes. During the processing, melt processing is one of the most important processing methods. During the melt processing, the quartz rod 32 needs to be heated at a high temperature. During high-temperature heating, the flame temperature is high due to the combustion method of a mixture of combustible gas and oxygen. In addition, in order to be heated evenly, the quartz rod 32 needs to be continuously rotated during the heating process. Therefore, during actual processing, burns may be caused by the burning of the high-temperature flame or the splashing of liquid quartz caused by the continuous rotation of the quartz rod 32, which may cause burns to personnel.

[0044] Therefore, in order to prevent people from getting burned, it is necessary to set up a fireproof backboard 1, and make the fireproof backboard 1 as a whole located in front of the spray gun 31. When the operator is behind the fireproof backboard 1, the high-temperature flame cannot directly contact the human body, so people can be prevented from being burned by the high-temperature flame, and the melting process of the columnar quartz can be observed through the fireproof backboard 1. Since the high-temperature flame has a certain gas pressure in the pipeline, it will have a longer outer flame when burning, and when the outer flame encounters the fireproof backboard 1, it will spread to both sides due to the gas pressure. In order to prevent the spreading flame from burning the human body, a starting cover plate 6 and a rotating cover plate 7 are set.

[0045] A group of starting cover plates 6 and a plurality of groups of rotating cover plates 7 are provided at the front of the rotating shaft 3 . The starting cover plates 6 and the rotating shaft 3 are fixedly connected, and the plurality of groups of rotating cover plates 7 and the rotating shaft 3 are movably connected.

[0046] In this embodiment, in order to prevent the high-temperature flame from spreading to both sides when contacting the fireproof back plate 1, a starting cover plate 6 and a rotating cover plate 7 are provided. By fixing the starting cover plate 6 to the rotating shaft 3, when the rotating shaft 3 is rotated by applying an external force, the starting cover plate 6 can be driven to rotate, and the starting cover plate 6 can drive the rotating cover plate 7 to rotate.

[0047] Because multiple sets of rotating cover plates 7 are provided on the rotating shaft 3, when the starting cover plate 6 rotates and drives the multiple sets of rotating cover plates 7 to rotate to the specified position, a cavity will be formed to block the high-temperature flame from spreading to both sides of the starting cover plate 6, thereby protecting the human body; and when the quartz rod 32 melts and rotates, since the starting cover plate 6 and the multiple sets of rotating cover plates 7 form a cavity, it can effectively prevent the high-temperature melted quartz from splashing to other places, thereby ensuring that the production plant will not be in danger of fire due to the high-temperature melted quartz.

[0048] like Figure 4 and Figure 5 As shown, the fireproof backboard 1 includes a flameproof cover plate 5, a pull-out plate gap 11, a support plate 14 and a hinge 15. Two groups of flameproof cover plates 5 are provided at the front of the fireproof backboard 1. The two groups of flameproof cover plates 5 are fixedly connected to the front of the fireproof backboard 1 and are located above the two groups of rotating shafts 3. Two groups of pull-out plate gaps 11 are symmetrically provided on the fireproof backboard 1. Two groups of support plates 14 are symmetrically provided at the front of the fireproof backboard 1. The lower part of each group of support plates 14 is fixedly connected to a hinge 15, and the lower part of the hinge 15 is fixedly connected to the fireproof backboard 1.

[0049] In this embodiment, in order to protect the rotating shaft 3 and its components from being damaged by high-temperature flames, a flame-proof cover plate 5 is provided. By symmetrically arranging the withdrawal plate gap 11, subsequent components can be inserted into the withdrawal plate gap 11, and the starting cover plate 6 and the rotating cover plate 7 on both sides are controlled.

[0050] At this time, two groups of support plates 14 are set at the front part of the fireproof backboard 1, and through a symmetrical arrangement, the two groups of support plates 14 can be respectively located on both sides of the fireproof backboard 1, and the lower part of each group of support plates 14 is connected to the hinge 15. If the support plate 14 is supported, the support plate 14 will be perpendicular to the fireproof backboard 1. If the support plate 14 is not supported, the support plate 14 will move downward through the hinge 15, and finally the support plate 14 will be close to the fireproof backboard 1.

[0051] like Figure 7 and Figure 8As shown, the rotating shaft 3 includes an anti-falling device 4, a traction rope 18 and a counterweight 19, the anti-falling device 4 is fixedly connected to the front part of the rotating shaft 3, the tail part of the traction rope 18 is fixedly connected to the tail part of the rotating shaft 3, part of the traction rope 18 is fixedly connected to the rotating shaft 3 by winding, and the front part of the traction rope 18 is fixedly connected to the counterweight 19, and the counterweight 19 is placed on the upper part of the support plate 14.

[0052] In this embodiment, in order to prevent the starting cover plate 6 and the multiple sets of rotating cover plates 7 from falling off when following the rotation of the rotating shaft 3, an anti-falling device 4 is provided, and the anti-falling device 4 is fixed to the front part of the rotating shaft 3, thereby fixing the starting cover plate 6 and the multiple sets of rotating cover plates 7.

[0053] One end of the traction rope 18 is fixed to the tail of the rotating shaft 3, and the other end of the traction rope 18 is connected to the counterweight 19. If the counterweight 19 is supported by a support at this time, the counterweight 19 will not move. If the support for the counterweight 19 is removed by external force, the counterweight 19 will fall downward due to its own weight. When the counterweight 19 falls, it will drive the traction rope 18 to follow the movement. The rear part of the rotating shaft 3 is wrapped with the traction rope 18. When the traction rope 18 falls with the counterweight 19, the wrapped part falls off the rotating shaft 3 and drives the rotating shaft 3 to start rotating.

[0054] like Figure 6 As shown, the starting cover plate 6 includes ejector pins 9 , and the ejector pins 9 are fixed to the edge of the starting cover plate 6 .

[0055] like Figure 6 As shown, the rotating cover plate 7 includes an annular groove 8, a ejector pin 9 and a clamping strip 10. The rotating cover plate 7 is provided with an annular groove 8, a clamping strip 10 is provided at the front of the annular groove 8, and the clamping strip 10 is fixedly connected to the edge of the rotating cover plate 7. The tail of the annular groove 8 is provided with an ejector pin 9, and the ejector pin 9 is fixedly connected to the edge of the rotating cover plate 7.

[0056] In this embodiment, the annular groove 8 is formed on the rotating cover plate 7 by using a cutting process, and the ejector pin 9 and the clamping strip 10 are respectively connected to the edges of the rotating cover plate 7, and the edges where the ejector pin 9 and the clamping strip 10 are located are not the same edge, but are axially symmetrical. Therefore, when multiple groups of rotating cover plates 7 start to rotate, when the rotating cover plates 7 of the previous group rotate following the external force, the ejector pin 9 on this rotating cover plate 7 will move along the annular groove 8 of the next group of rotating cover plates 7.

[0057] As the previous group of rotating cover plates 7 moves, the ejector pins 9 on the previous group of rotating cover plates 7 will eventually move to the clamping strips 10 on the next group of rotating cover plates 7. At this time, the clamping strips 10 fix the ejector pins 9 on the previous group of rotating cover plates 7. As the previous group of rotating cover plates 7 continues to rotate, the ejector pins 9 on the previous group of rotating cover plates 7 will continue to rotate. The continuous rotation of the ejector pins 9 on the previous group of rotating cover plates 7 will drive the clamping strips 10 on the next group of rotating cover plates 7 to rotate, and then the clamping strips 10 on the next group of rotating cover plates 7 will drive the rotating cover plates 7 to rotate. This process continues, so that multiple groups of rotating cover plates 7 can eventually reach the specified position.

[0058] In summary, the starting cover plate 6 drives the first set of rotating cover plates 7 to rotate also using the same principle.

[0059] like Figure 5 , Figure 7 and Figure 8 As shown, the quartz melting processing fireproof cover includes a drawer plate 12, the cross-sectional size of the drawer plate 12 is the same as the drawer plate gap 11, the drawer plate 12 includes a drawer plate handle 13, a lock buckle 20 and a hanging rope 21, the drawer plate handle 13 is fixedly connected to the tail of the drawer plate 12, the lock buckle 20 is fixedly connected to the front of the drawer plate 12, and the hanging rope 21 is detachably connected to the lower part of the lock buckle 20.

[0060] In this embodiment, when the cross-sectional size of the drawer 12 is the same as that of the drawer slit 11, the drawer 12 can be inserted into the drawer slit 11. When the drawer 12 is inserted into the drawer slit 11, its front half is located in front of the fireproof back plate 1, and the half of the drawer 12 is fixedly connected with the lock buckle 20, and the rear half of the drawer 12 is provided with a drawer handle 13. At this time, the hanging rope 21 can be installed at the lower part of the lock buckle 20.

[0061] At this time, the hanging rope 21 should be made of a material that is easily broken, or a slipknot should be used to tie the hanging rope 21 to the lower part of the lock buckle 20 when installing the hanging rope 21, and the other end of the hanging rope 21 is connected to other devices. When the operator holds the drawer handle 13 and pulls the drawer 12 backward, one end of the hanging rope 21 moves backward due to the external force, while the other end does not move because it is fixedly connected to other devices. This ensures that when the drawer 12 is completely pulled out of the fireproof backboard 1, the hanging rope 21 in front of the drawer 12 can be completely broken, or the slipknot is opened to separate the hanging rope 21 from the lock buckle 20.

[0062] like Figure 7 and Figure 8 As shown, the support plate 14 includes a spring connector 16 and a spring 17 . The upper portion of the support plate 14 is provided with the spring connector 16 . One end of the spring 17 is connected to the spring connector 16 , and the other end is connected to the hanging rope 21 .

[0063] In this embodiment, a spring connector 16 is fixed to the upper portion of the support plate 14, and one end of the spring 17 is fixed to the spring connector 16, and the other end is connected to the hanging rope 21, so that the spring 17 fixes the support plate 14 through its own elastic force, so that it remains in a fixed position.

[0064] When the operator holds the drawer handle 13 and pulls the drawer 12 backward, the hanging rope 21 in front of the drawer 12 is broken or falls off, and one end of the spring 17 loses the tension, so that the spring 17 falls off. As the spring 17 falls off, the support plate 14 loses its supporting force, so that the support plate 14 cannot maintain balance, rotates downward, and finally becomes flush with the fireproof back plate 1.

[0065] like Figure 1 As shown, it includes a gripper 23, a fixer 24, a side panel 25, a motor shaft 26, a base panel 27, a slide rail 28, a sliding base 29, and a spray gun 31. The front part of the fireproof back panel 1 is symmetrically provided with two groups of grippers 23. The fixer 24 is fixedly connected to the rear of each group of grippers 23. The rear part of the fixer 24 is fixedly connected to the motor shaft 26. The side panel 25 is rotatably connected to the motor shaft 26 through a bearing. The base panel 27 is arranged at the lower part of the side panel 25. The upper part of the base panel 27 is provided with a slide rail 28. The slide rail 28 is fixed to the side panel 25. The sliding base 29 is movably connected to the slide rail 28 through a slide groove. The spray gun 31 is located at the upper part of the sliding base 29.

[0066] In this embodiment, the motor shaft 26 is fixed to the rear portion of the holder 24, and the gripper 23 is fixed to the front portion of the holder 24, and the side plate 25 is rotatably connected to the motor shaft 26 via a bearing. Therefore, when the external motor is connected to the motor shaft 26 and started, the motor can drive the motor shaft 26 to rotate inside the side plate 25, and then drive the holder 24 to rotate together with the motor shaft 26, and the holder 24 drives the gripper 23 to rotate.

[0067] The gripper 23 tightly grasps the quartz rod 32. When the gripper 23 rotates, the quartz rod 32 can rotate accordingly, so that the quartz rod 32 can maintain uniform heating when heated by a high-temperature flame, thereby ensuring processing accuracy; and because the slide rail 28 is fixed to the side plate 25, and the sliding base 29 is movably connected to the slide rail 28 through the slide groove, the sliding base 29 can slide back and forth between the side plates 25 on both sides.

[0068] like Figure 1 As shown, the sliding base 29 includes a connecting column 22 and a spray gun support column 30, one end of the connecting column 22 is fixedly connected to the sliding base 29, and the other end is fixedly connected to the fireproof backboard 1, one end of the spray gun support column 30 is fixedly connected to the sliding base 29, and the other end is detachably connected to the spray gun 31.

[0069] In this embodiment, in order to ensure that the starting cover plate 6 and the rotating cover plate 7 can always protect the operator and prevent the melted quartz from splashing and causing a fire, it is necessary to keep the fireproof back plate 1, the starting cover plate 6 and the rotating cover plate 7 directly in front of the spray gun 31. For this purpose, a connecting column 22 and a spray gun support column 30 are provided.

[0070] By fixing the connecting column 22 and the spray gun support column 30 on the sliding base 29 at the same time, and the other ends of the connecting column 22 and the spray gun support column 30 are respectively connected to the fireproof backboard 1 and the spray gun 31, when the operator holds the drawer handle 13 and pushes the fireproof backboard 1 left and right, the fireproof backboard 1 and the spray gun 31 can move simultaneously with the movement of the sliding base 29, ensuring the directional consistency of the fireproof backboard 1 and the spray gun 31, so that the fireproof backboard 1, the starting cover plate 6 and the rotating cover plate 7 are always in front of the spray gun 31, thereby ensuring the safety of this embodiment during use.

[0071] The fireproof back plate 1, the flameproof cover plate 5, the starting cover plate 6 and the rotating cover plate 7 are all made of fireproof materials.

[0072] In this embodiment, since the quartz melting processing is a long process, in order to prevent the fireproof back plate 1, the flameproof cover plate 5, the starting cover plate 6 and the rotating cover plate 7 and other components from burning during this long process and causing casualties, it is necessary to use fireproof materials to make the fireproof back plate 1, the flameproof cover plate 5, the starting cover plate 6 and the rotating cover plate 7.
