Description

Technical Field

[0001] This invention relates to the field of waste heat recovery and utilization technology for vacuum enrichment of antimony trioxide from crude antimony, specifically to a waste heat recovery and utilization device for vacuum enrichment of antimony trioxide from crude antimony. Background Technology

[0002] Vacuum enrichment of antimony trioxide from crude antimony is an advanced metallurgical process for purifying and producing high-purity antimony trioxide from crude antimony (metallic antimony containing impurities). It utilizes the sublimation-condensation principle under vacuum to directly separate and purify antimony trioxide from crude antimony. Vacuum enrichment of antimony trioxide from crude antimony is a green metallurgical technology that takes advantage of the easy sublimation of antimony trioxide under vacuum conditions to directly convert the antimony in crude antimony into high-value-added pure antimony trioxide products, while realizing the comprehensive utilization of resources and environmental protection.

[0003] Currently, heat exchangers are typically used to cool the gas produced after the vacuum enrichment of antimony trioxide from crude antimony. The heat from the gas is then recovered and utilized. However, the gas produced after the reaction contains gaseous Sb₂O₃, which easily condenses as it flows inside the heat exchanger. When gaseous Sb₂O₃ condenses inside the heat exchanger, it can cause blockage, preventing the heat exchanger from operating properly and affecting the heat exchange efficiency of the gas.

A conical block is threadedly connected to the surface of the lower screw, and a through-hole scraper is fixedly connected to the end of the conical block.

[0012] Furthermore, the lower screw extends into the interior of the transmission frame at the end away from the protective frame, and the upper screw extends into the interior of the end tube at the end away from the protective frame. The lower screw and the upper screw are located inside the two extrusion cylinders respectively, and the conical block is in contact with the inner wall of the lower tube.

[0014] Furthermore, the centralized component includes a cleaning frame, a round shaft fixedly connected to the inner wall of the cleaning frame, a round hole rod fixedly connected to the bottom of the round shaft rod, a spring fixedly connected to the top of the inner wall of the round hole rod, an auxiliary frame fixedly connected to the top of the cleaning frame, a disc fixedly connected to the inner wall of the auxiliary frame, an elastic rod fixedly connected to the surface of the disc, a limit plate fixedly connected to the end of the elastic rod away from the disc, an expansion plate fixedly connected to the top of the limit plate, an elliptical block fixedly connected to the surface of the lower screw, a triangular plate fixedly connected to the top of the inner wall of the cooling frame, a right-angled groove formed on the inner wall of the triangular plate, a right-angled plate fixedly connected to the top of the disc, and a lifting ring fixedly connected to the end of the right-angled plate away from the disc.

[0015] Furthermore, the bottom of the circular hole rod extends to the bottom of the inner wall of the cooling rack and is slidably connected to the bottom of the inner wall of the cooling rack; the bottom of the spring is fixedly connected to the bottom of the inner wall of the cooling rack; the surface of the cleaning rack is slidably connected to the inner wall of the cooling rack; the surface of the auxiliary rack is in contact with the inner wall of the cooling rack; and the auxiliary rack located below the lower screw is provided with a break.

[0016] Furthermore, there are two discs and four elastic rods. The four elastic rods are arranged in two groups, with two rods in each group. The two elastic rods are symmetrically arranged around the discs. The surface of the expansion plate is in contact with the surface of the triangular plate. The surface of the right-angle plate is adapted to the inner wall of the right-angle groove. The surface of the lifting ring is in contact with the inner wall of the vertical tube.

[0017] The present invention has the following beneficial effects:

[0018] The airflow generated by the fan of this invention enters the interior of the energy storage rack through a bend pipe. After entering the interior of the energy storage rack, the airflow blows the high temperature in the energy storage rack into the first transfer pipe. After connecting the ends of the first and second transfer pipes to the corresponding storage or transfer devices, the high temperature in the gas is discharged into the corresponding device through the first transfer pipe, thereby completing the recovery and utilization of the high temperature in the gas. When the cooled gas flows in the upper pipe, the residual heat inside is conducted to the interior of the cylindrical rack by the second heat dissipation fin. When the airflow in the bend pipe flows inside the cylindrical rack, the airflow will transfer the residual heat to the second transfer pipe. The second transfer pipe is used to transfer the gas to the corresponding location for recovery and utilization, thereby improving the utilization effect of waste heat.

[0019] When gas needs to enter the lower tube, the power unit is activated to rotate the lower screw. As the lower screw rotates, it pushes the conical block towards the interior of the transfer frame. The conical block and the sealing block slide on the surfaces of two positioning plates, which limit their movement. This ensures that the conical block and the sealing block move stably with the rotation of the upper and lower screws. As the conical block moves, it pushes the extrusion cylinder to compress the elastic frame. At this point, the conical block and the lower tube are connected, allowing the gas in the vacuum high-temperature furnace to quickly enter the lower tube for cooling, preventing poor sealing from affecting the vacuum high-temperature furnace. The gas intake is adjusted by regulating the distance between the conical block and the lower tube to prevent excessive intake from affecting the cooling effect. As the sealing block moves with the upper screw, it enters the interior of the end tube, which then connects with the upper tube to facilitate the collection and discharge of cooled gas. When the conical block and the sealing block contact the inner walls of the lower and upper tubes respectively, the extrusion cylinder uses the elasticity of the spring frame to squeeze the ends of the conical block and the sealing block, improving the sealing effect between the conical block and the lower screw. This prevents poor sealing from affecting the vacuum operation of the vacuum high-temperature furnace and improves the processing effect of vacuum enrichment of antimony trioxide for crude antimony.

[0020] In this invention, after the gas in the vacuum high-temperature furnace has completely entered the interior of the lower tube, the power device is activated to drive the lower and upper screws to rotate. When the lower screw rotates in reverse, it pushes the conical block to slide inside the lower tube. As the conical block moves, it pushes the through-hole scraper to clean the inner wall of the lower tube, preventing gaseous Sb2O3 in the gas from condensing inside the lower tube and causing blockage, which would affect the utilization effect of the waste heat from vacuum enrichment of antimony trioxide in crude antimony. The through-hole scraper pushes the condensed gaseous Sb2O3 into the interior of the cooling rack, facilitating centralized treatment of the condensed gaseous Sb2O3 through the sealing door. When the sealing block rotates with the upper screw, it moves inside the upper tube, cleaning the inner wall of the upper tube and preventing gaseous Sb2O3 from condensing inside the upper tube and causing blockage, thereby improving the utilization effect of waste heat.

[0021] In this invention, when the screw rotates, it drives the elliptical block to rotate. The elliptical block, during rotation, contacts and presses the round shaft downwards. The downward movement of the round shaft pushes the cleaning frame downwards, which in turn drives the auxiliary frame downwards. As the elliptical block rotates, the spring elastically pushes the round shaft upwards, causing the cleaning frame and auxiliary frame to move up and down inside the cooling rack. The cleaning frame and auxiliary frame clean the inner wall of the cooling rack, preventing gaseous Sb2O3 from condensing on its surface and affecting the cooling effect. When the auxiliary frame moves, it pushes the expansion plate through the connection between the elastic rod and the limiting plate. The expansion plate cleans the surface of the triangular plate, causing any condensed gaseous Sb2O3 to fall to the bottom of the cooling rack, facilitating centralized treatment of the solidified gaseous Sb2O3 and improving the cooling effect of the cooling rack. As the expansion plate moves across the surface of the triangular plate, it pulls the elastic rod to extend, ensuring the expansion plate tightly adheres to the surface of the triangular plate for cleaning.

[0022] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Please see Figures 1-12 As shown, the present invention is a waste heat recovery and utilization device for vacuum enrichment of antimony trioxide in crude antimony, including a base plate 2, a vacuum high-temperature furnace 1 installed on the top of the base plate 2, and a cooling component 3 connected to the surface of the vacuum high-temperature furnace 1.

[0040] Cooling component 3 includes a transfer frame 10, which is connected to the lower surface of the vacuum high-temperature furnace 1. A lower pipe 11 is connected to the end of the transfer frame 10 away from the vacuum high-temperature furnace 1. A cooling frame 12 is connected to the end of the lower pipe 11 away from the transfer frame 10. A sealing door is hinged to the surface of the cooling frame 12. A cooling device 17 is installed at the end of the cooling frame 12 away from the sealing door. A vertical pipe 13 is connected to the top of the cooling frame 12. An upper pipe 14 is connected to the upper surface of the vertical pipe 13. An end pipe 15 is connected to the end pipe 14 away from the vertical pipe 13. A discharge valve 16 is connected to the surface of the end pipe 15. The airflow generated by the fan 21 enters the interior of the energy storage rack 20 through the bend pipe 22. After entering the interior of the energy storage rack 20, the airflow blows the high temperature inside the energy storage rack 20 into the transfer pipe 25. After the ends of the first and second transfer pipes 25 and 24 are connected to the corresponding storage or transfer devices, the high temperature in the gas is discharged into the corresponding device through the first transfer pipe 25, thereby completing the recovery and utilization of the high temperature in the gas. When the cooled gas flows in the upper pipe 14, the residual heat inside is conducted to the inside of the cylindrical frame 23 by the second heat dissipation fin 27. When the airflow in the bend 22 flows inside the cylindrical frame 23, the airflow will transfer the residual heat to the second transfer pipe 24. The second transfer pipe 24 is used to transfer the gas to the corresponding place for recovery and utilization, improving the utilization effect of residual heat. The top of the base plate 2 is provided with a recovery component 4, the inside of the lower pipe 11 and the upper pipe 14 is provided with an anti-blocking component 5, and the inside of the cooling rack 12 is provided with a concentration component 6.

[0041] The bottom of the cooling rack 12 is fixedly connected to the top of the base plate 2, the upper tube 14 is located above the lower tube 11, and the upper tube 14 and the lower tube 11 are set horizontally.

[0042] The recycling component 4 includes an energy storage rack 20. The bottom of the energy storage rack 20 is fixedly connected to the top of the base plate 2. A cylindrical frame 23 is fixedly connected to the top of the energy storage rack 20. The energy storage rack 20 and the cylindrical frame 23 are interconnected through a bend 22. A fan 21 is connected to the surface of the bend 22. The end of the fan 21 away from the bend 22 is fixedly connected to the surface of the energy storage rack 20. A first adapter pipe 25 is connected to the end of the energy storage rack 20 away from the bend 22. A second adapter pipe 24 is connected to the end of the cylindrical frame 23 away from the bend 22. A first heat dissipation fin 26 is fixedly connected to the surface of the lower pipe 11. A second heat dissipation fin 27 is fixedly connected to the surface of the upper pipe 14.

[0043] The lower tube 11 is located inside the energy storage rack 20, the upper tube 14 is located inside the cylindrical rack 23, and the inner wall of the energy storage rack 20 is fixedly connected to the surface of the lower tube 11, the inner wall of the cylindrical rack 23 is fixedly connected to the surface of the upper tube 14, the first heat dissipation fin 26 is located inside the energy storage rack 20, and the second heat dissipation fin 27 is located inside the cylindrical rack 23.

[0044] The anti-blocking component 5 includes a protective frame 30, the surface of which is fixedly connected to the surface of the cooling rack 12. A lower screw 35 and an upper screw 34 are rotatably connected to the inner wall of the protective frame 30. A power device 31 is fixedly connected to the surface of the protective frame 30, and the output end of the power device 31 is fixedly connected to the end of the lower screw 35. Pulleys 33 are fixedly connected to the surfaces of the lower screw 35 and the upper screw 34, respectively, and the two pulleys 33 are connected by a belt 32. A sliding hole frame 36 is fixedly connected to the top of the inner wall of the transmission rack 10 and the top of the inner wall of the end tube 15, respectively. A spring frame is fixedly connected to the surface of the sliding hole frame 36. 40. An extrusion cylinder 39 is slidably connected to the inner wall of the sliding frame 36. The end of the extrusion cylinder 39 is fixedly connected to the elastic frame 40. Positioning plates 37 are fixedly connected to the top of the inner wall of the lower tube 11 and the top of the inner wall of the upper tube 14, respectively. A conical block 41 is threadedly connected to the surface of the lower screw 35. A through-hole scraper 42 is fixedly connected to the end of the conical block 41. A sealing block 38 is threadedly connected to the surface of the upper screw 34. When gas needs to enter the interior of the lower tube 11, the power device 31 is started to drive the lower screw 35 to rotate. When the lower screw 35 rotates, it will push the conical block 41 to move into the interior of the transmission frame 10. The conical block 41 and sealing block 38 slide on the surfaces of the two positioning plates 37, respectively. The positioning plates 37 limit their movement, allowing the conical block 41 and sealing block 38 to move stably with the rotation of the upper screw 34 and the lower screw 35. When the conical block 41 moves, it pushes the extrusion cylinder 39 to extrude the elastic frame 40. At this time, the conical block 41 and the lower tube 11 are in a connected state, and the gas in the vacuum high-temperature furnace 1 will quickly enter the lower tube 11 for cooling treatment, avoiding poor sealing from affecting the operation of the vacuum high-temperature furnace 1. The gas intake is adjusted by adjusting the distance between the conical block 41 and the lower tube 11. To avoid excessive air intake affecting the cooling effect, the sealing block 38 enters the interior of the end tube 15 as the upper screw 34 moves. At this time, the end tube 15 will be connected to the upper tube 14 to facilitate the collection and discharge of cooled gas. When the conical block 41 and the sealing block 38 contact the inner walls of the lower tube 11 and the upper tube 14 respectively, the extrusion cylinder 39 will use the elasticity of the elastic frame 40 to extrude the ends of the conical block 41 and the sealing block 38, thereby improving the sealing effect between the conical block 41 and the lower screw 35. This prevents poor sealing from affecting the vacuum operation of the vacuum high-temperature furnace 1 and improves the processing effect of vacuum enrichment of antimony trioxide for crude antimony.

[0045] The lower screw 35 extends into the interior of the transfer frame 10 at the end away from the protective frame 30, and the upper screw 34 extends into the interior of the end tube 15 at the end away from the protective frame 30. The lower screw 35 and the upper screw 34 are located inside the two extrusion cylinders 39, respectively. The conical block 41 contacts the inner wall of the lower tube 11. After the gas in the vacuum high-temperature furnace 1 has completely entered the interior of the lower tube 11, the power device 31 is started to drive the lower screw 35 and the upper screw 34 to rotate. When the lower screw 35 rotates in reverse, it pushes the conical block 41 to slide inside the lower tube 11. When the conical block 41 moves, it pushes the through-hole scraper 42 against the interior of the lower tube 11. The wall is cleaned to prevent gaseous Sb2O3 in the gas from condensing inside the lower tube 11 and causing blockage, which would affect the utilization of waste heat from vacuum enrichment of antimony trioxide in crude antimony. The through-hole scraper 42 pushes the condensed gaseous Sb2O3 into the interior of the cooling rack 12, making it convenient to centrally process the condensed gaseous Sb2O3 through the sealing door. The sealing block 38 moves inside the upper tube 14 as the upper screw 34 rotates, cleaning the inner wall of the upper tube 14 to prevent gaseous Sb2O3 from condensing in the upper tube 14 and causing blockage, thereby improving the utilization of waste heat.

[0046] The surface of the through-hole scraper 42 contacts the inner wall of the lower tube 11, the end of the extrusion cylinder 39 away from the elastic frame 40 contacts the end of the conical block 41, the inner wall of the conical block 41 is slidably connected to the surface of the positioning plate 37, the surface of the sealing block 38 contacts the inner wall of the upper tube 14, and the inner wall of the sealing block 38 is slidably connected to the surface of the positioning plate 37.

[0047] The central component 6 includes a cleaning frame 50. A round shaft 57 is fixedly connected to the inner wall of the cleaning frame 50. A round hole rod 58 is fixedly connected to the bottom of the round shaft 57. A spring 56 is fixedly connected to the top of the inner wall of the round hole rod 58. An auxiliary frame 51 is fixedly connected to the top of the cleaning frame 50. A disc 59 is fixedly connected to the inner wall of the auxiliary frame 51. An elastic rod 60 is fixedly connected to the surface of the disc 59. A limiting plate 63 is fixedly connected to the end of the elastic rod 60 away from the disc 59. An expansion joint is fixedly connected to the top of the limiting plate 63. An elliptical block 55 is fixedly connected to the surface of the plate 62 and the lower screw 35. A triangular plate 61 is fixedly connected to the top of the inner wall of the cooling rack 12. A right-angled groove 52 is opened on the inner wall of the triangular plate 61. A right-angled plate 54 is fixedly connected to the top of the disc 59. A lifting ring 53 is fixedly connected to the end of the right-angled plate 54 away from the disc 59. When the lower screw 35 rotates, it will drive the elliptical block 55 to rotate. When the elliptical block 55 rotates, it will contact the round shaft 57 and squeeze it to move downward. When the round shaft 57 moves downward, it will push... The cleaning frame 50 moves downward, which in turn moves the auxiliary frame 51 downward. When the elliptical block 55 rotates, the spring 56 pushes the round shaft 57 upward through elasticity, causing the cleaning frame 50 and the auxiliary frame 51 to move up and down inside the cooling rack 12. The cleaning frame 50 and the auxiliary frame 51 clean the inner wall of the cooling rack 12, preventing gaseous Sb2O3 from condensing on the surface of the cooling rack 12 and affecting the cooling effect. When the auxiliary frame 51 moves, it is limited by the elastic rod 60. The connection of plate 63 pushes the expansion plate 62 to move. When the expansion plate 62 moves, it cleans the surface of the triangle plate 61, causing the gaseous Sb2O3 condensed on the surface of the triangle plate 61 to fall to the bottom of the cooling rack 12. This facilitates the centralized treatment of the solidified gaseous Sb2O3 and improves the cooling effect of the cooling rack 12 on the gas. When the expansion plate 62 moves on the surface of the triangle plate 61, it pulls the elastic rod 60 to extend, so that the expansion plate 62 will fit tightly against the surface of the triangle plate 61 to clean it.

[0048] The bottom of the round hole rod 58 extends to the bottom of the inner wall of the cooling rack 12 and is slidably connected to the bottom of the inner wall of the cooling rack 12. The bottom of the spring 56 is fixedly connected to the bottom of the inner wall of the cooling rack 12. The surface of the cleaning rack 50 is slidably connected to the inner wall of the cooling rack 12. The surface of the auxiliary rack 51 is in contact with the inner wall of the cooling rack 12, and the auxiliary rack 51 located below the lower screw 35 is set with a break.

[0049] There are two discs 59 and four elastic rods 60. The four elastic rods 60 are set in two groups, and there are two in each group. The two elastic rods 60 are symmetrically arranged with the discs 59 as the center. The surface of the expansion plate 62 is in contact with the surface of the triangular plate 61. The surface of the right angle plate 54 is adapted to the inner wall of the right angle groove 52. The surface of the lifting ring 53 is in contact with the inner wall of the vertical tube 13.

[0050] When the vacuum high-temperature furnace 1 is used to vacuum enrich antimony trioxide of crude antimony, the gas after the reaction of crude antimony vacuum enrichment antimony trioxide will enter the lower tube 11 through the transfer frame 10. The gas will be transferred to the interior of the cooling frame 12 for cooling treatment through the lower tube 11. When the cooling device 17 is started, the cooling device 17 will cool the cooling frame 12. At this time, the gas entering the interior of the cooling device 17 will be fully cooled. The cooled gas will enter the upper tube 14 through the vertical tube 13. The upper tube 14 will transfer the gas to the end tube 15 and discharge it through the exhaust valve 16, which will improve the cooling effect of the gas. When the gas flows in the lower tube 11 and the upper tube 14, the heat in the gas will be absorbed by the recovery component 4. The heat will be recovered and utilized by the recovery component 4.

[0051] When gas enters the lower tube 11 from inside the vacuum high-temperature furnace 1, it carries high temperature into the lower tube 11. At this time, the high temperature in the lower tube 11 is absorbed by the heat dissipation fins 26 and accumulates inside the energy storage rack 20. Then, the fan 21 is started, and the airflow generated by the fan 21 enters the energy storage rack 20 through the bend 22. After entering the energy storage rack 20, the airflow blows the high temperature from the energy storage rack 20 into the transfer pipe 25. The corresponding storage devices are connected to the ends of the transfer pipe 25 and the transfer pipe 24. After the placement or transfer device, the high temperature in the gas is discharged into the corresponding device through the transfer pipe 25, thereby completing the recovery and utilization of the high temperature in the gas. When the cooled gas flows in the upper pipe 14, the residual heat inside is conducted to the inside of the cylindrical frame 23 by the heat dissipation fins 27. When the airflow in the bend pipe 22 flows inside the cylindrical frame 23, the airflow will transfer the residual heat to the transfer pipe 24. The transfer pipe 24 is used to transfer the gas to the corresponding place for recovery and utilization, thereby improving the utilization effect of the residual heat.

[0052] When gas needs to enter the lower tube 11, the power unit 31 is activated to drive the lower screw 35 to rotate. As the lower screw 35 rotates, it pushes the conical block 41 towards the interior of the transfer frame 10. The conical block 41 and the sealing block 38 slide on the surfaces of the two positioning plates 37, which limit their movement, ensuring that the conical block 41 and the sealing block 38 move stably with the rotation of the upper screw 34 and the lower screw 35. As the conical block 41 moves, it pushes the extrusion cylinder 39 to compress the elastic frame 40. At this point, the conical block 41 and the lower tube 11 are connected, and the gas in the vacuum high-temperature furnace 1 quickly enters the lower tube 11 for cooling, preventing poor sealing from affecting the vacuum high-temperature process. In the operation of furnace 1, the gas intake is adjusted by adjusting the distance between the conical block 41 and the lower tube 11 to avoid excessive intake affecting the cooling effect. When the sealing block 38 moves with the upper screw 34, it enters the interior of the end tube 15. At this time, the end tube 15 will be connected to the upper tube 14 to facilitate the discharge and collection of cooled gas. When the conical block 41 and the sealing block 38 contact the inner walls of the lower tube 11 and the upper tube 14 respectively, the extrusion cylinder 39 will use the elasticity of the elastic frame 40 to extrude the ends of the conical block 41 and the sealing block 38, thereby improving the sealing effect between the conical block 41 and the lower screw 35 and avoiding poor sealing effect from affecting the vacuum operation of the vacuum high-temperature furnace 1, thus improving the processing effect of vacuum enrichment of antimony trioxide for crude antimony.

[0053] After the gas in the vacuum high-temperature furnace 1 has completely entered the interior of the lower tube 11, the power device 31 is started to drive the lower screw 35 and the upper screw 34 to rotate. When the lower screw 35 rotates, it pushes the conical block 41 to slide inside the lower tube 11. When the conical block 41 moves, it pushes the through-hole scraper 42 to clean the inner wall of the lower tube 11, so as to prevent the gaseous Sb2O3 in the gas from condensing inside the lower tube 11 and causing blockage, which would affect the utilization effect of the waste heat of vacuum enrichment of antimony trioxide for crude antimony. The through-hole scraper 42 will push the condensed gaseous Sb2O3 into the interior of the cooling rack 12, so as to facilitate the centralized treatment of the condensed gaseous Sb2O3 through the sealing door. When the sealing block 38 rotates with the upper screw 34, it will move inside the upper tube 14. The sealing block 38 is used to clean the inner wall of the upper tube 14, so as to prevent the gaseous Sb2O3 from condensing in the upper tube 14 and causing blockage, thereby improving the utilization effect of waste heat.

[0054] When the lower screw 35 rotates, it drives the elliptical block 55 to rotate. As the elliptical block 55 rotates, it contacts and presses the round shaft 57 downwards. The downward movement of the round shaft 57 pushes the cleaning frame 50 downwards, which in turn drives the auxiliary frame 51 downwards. While the elliptical block 55 rotates, the spring 56 elastically pushes the round shaft 57 upwards, causing the cleaning frame 50 and the auxiliary frame 51 to move up and down inside the cooling rack 12. The cleaning frame 50 and the auxiliary frame 51 clean the inner wall of the cooling rack 12, preventing gaseous Sb2O3 from condensing on the cooling rack 12. The surface of the triangular plate 61 affects the cooling effect. When the auxiliary frame 51 moves, it pushes the expansion plate 62 to move through the connection between the elastic rod 60 and the limiting plate 63. When the expansion plate 62 moves, it cleans the surface of the triangular plate 61, so that the gaseous Sb2O3 condensed on the surface of the triangular plate 61 will fall to the bottom of the cooling frame 12, which facilitates the centralized treatment of the solidified gaseous Sb2O3 and improves the cooling effect of the cooling frame 12 on the gas. When the expansion plate 62 moves on the surface of the triangular plate 61, it will pull the elastic rod 60 to extend, so that the expansion plate 62 will fit tightly against the surface of the triangular plate 61 to clean it.
