[0039] In this embodiment, when it is necessary to store some specific substances in vacuum, the fixed tube 119 is first put on the quartz tube, and then the elastic sealing ring 118 is put on. Then, the top of the quartz tube is connected to the rotating end of the control box 109 by using the cooperation of the sealing ring 118 and the fixed tube 119. Then, the protective mechanism 2 is installed. When they are ready together, the nozzle position of the flamethrower 107 is adjusted directly by using the cooperation of the adjustable bracket 105 until the nozzle of the flamethrower 107 passes through the opening of the high-temperature resistant opening ring 208 facing it and reaches a suitable heating position. Then, the control button on the control box 109 is used to close an electric vacuum valve inside it (control whether the one-way valve 111 can supply air to the inside of the control box 109). , and then use the controller 217 to start the vacuum pump 102. At this time, the started vacuum pump 102 will, with the cooperation of the air pipe 117, the two shells 115, the three-way joint 113, the air release valve 114 and the control box 109 connected thereto, allow the bottom of the rotating end of the control box 109 to obtain suction.

The motor 214 is started by the controller 217, and the control box 109 is used to rotate its rotating end. At this time, the rotating end of the rotating control box 109 will directly drive the quartz tube filled with substances and in a vacuum state to rotate under the cooperation of the sealing ring 118 and the fixed tube 119. At the same time, the fire sprayed from the flame spray end of the ignited flamethrower 107 can evenly heat the rotating quartz tube. When the quartz tube is continuously heated, the heated position of the quartz tube will soften, and the softened quartz material will fuse together, that is, the sealing operation is realized. When it is necessary to release the gas, the venting valve 114 can be directly opened. When the quartz tube needs to be injected with inert gas after the vacuum operation is completed, the gas inlet joint 112 is directly connected to the gas outlet end of the tube for supplying inert gas.Then, by using the cooperation of the air inlet connector 112, the control box 109, the sealing ring 118, the fixed tube 119 and the rotating end of the control box 109, the inert gas can be injected into the interior of the quartz tube.

[0040] The effect and working principle of the whole mechanism are as follows: when it is necessary to store some specific substances in vacuum, a clean quartz tube of suitable length, thickness and thickness is selected, and the substances to be stored in vacuum are loaded, and then the controller 217 is connected to the external power supply, and then the fixed tube 119 is first put on the quartz tube, and then the elastic sealing ring 118 is put on, and then the top of the quartz tube is connected to the rotating end of the control box 109 by using the cooperation of the sealing ring 118 and the fixed tube 119, that is, the inside of the quartz tube and the inside of the rotating end of the control box 109 are connected, and then the high temperature resistant tube 204 with the high temperature resistant plug 206 and multiple high temperature resistant open rings 208 is put on the outside of the quartz tube, and then the ring 201 and the connecting rod are used. 202, adjust the position of the arc block 203, and then fix the arc block 203 and the high temperature resistant tube 204 together to fix the high temperature resistant tube 204. Finally, use the cooperation of the hand-tightening ring 210 to install the high temperature resistant collecting tube 209 on the bottom of the high temperature resistant tube 204. After the installation of the high temperature resistant collecting tube 209 is completed, the air inlet end of the high temperature resistant connecting tube 216 is connected to the air outlet end of the high temperature resistant collecting tube 209. After completing this operation, according to the position of the quartz tube required to be sealed, align the opening of the high temperature resistant open ring 208 of the corresponding height with the flamethrower of the flamethrower 107, turn the openings of all the remaining high temperature resistant open rings 208 away from the rectangular hole 207, and complete the high temperature resistant open ring 208. After adjusting the opening position, connect the air inlet end of the flamethrower 107 to the output end of the pipe for conveying combustible gas. When they are ready, adjust the nozzle position of the flamethrower 107 directly by means of the adjustable bracket 105 until the nozzle of the flamethrower 107 passes through the opening of the opposite high-temperature resistant opening ring 208 and reaches a suitable heating position. Then, use the control button on the control box 109 to close an electric vacuum valve inside it (control whether the one-way valve 111 can supply air to the inside of the control box 109). Then use the controller 217 to start the vacuum pump 102. At this time, the started vacuum pump 102 will be connected to the air pipe 117, the two housings 115, the three-way joint 113, the vent valve 114 and the control box 109. The bottom of the rotating end of the control box 109 that has obtained suction will directly extract the air in the quartz tube with the cooperation of the sealing ring 118 and the fixed tube 119. The extracted air will then be directly transported to the inside of the three-way joint 113 through the cooperation of the control box 109, and then transported to the inside of one of the shells 115. When the air enters the inside of the other shell 115 from the inside of one of the shells 115, the impurities (carried by substances) that may be mixed in the air can be filtered and retained in the inside of one of the shells 115 under the action of the filter 116, and the filtered air is directly transported to the inside of the air pipe 117 through the other shell 115.Then it is ejected from the outlet of the vacuum pump 102. At the same time, the pressure gauge 110 will also constantly detect the vacuum condition of the quartz tube. When the quartz tube reaches the vacuum condition, the control button on the control box 109 is directly used to close another electric vacuum valve inside it (control whether the air inlet end of the three-way joint 113 can suck air), and then the vacuum pump 102 is turned off by the controller 217, and then the gas is supplied to the inside of the flamethrower 107. After that, the igniter is used to ignite the combustible gas ejected from the outlet of the flamethrower 107, and the controller 217 is used to start the motor 214, and the control box 109 is used to rotate its rotating end. At this time, the rotating end of the rotating control box 109 will directly drive the installation under the cooperation of the sealing ring 118 and the fixed tube 119. The quartz tube with material and in a vacuum state rotates, and the fire sprayed from the flame spraying end of the ignited flamethrower 107 can evenly heat the rotating quartz tube. When the quartz tube is continuously heated, the heated position of the quartz tube will soften, and the softened quartz material will fuse together, that is, the sealing operation is realized. At the same time, the started motor 214 will rotate the high temperature resistant blades 215 under the cooperation of the high temperature resistant block 213, the three-way pipe 211 and the rotating rod 218, and the rotating high temperature resistant blades 215 will quickly draw away the heat dispersed in the inside of the high temperature resistant tube 204 generated when the quartz tube is heated under the cooperation of the high temperature resistant block 213, the high temperature resistant connecting pipe 216, the high temperature resistant cover 212 and the high temperature collecting pipe 209, and then the normal temperature air in the environment The gas will be drawn into the interior of the high temperature resistant tube 204, and then the drawn heat will first pass through the interior of the high temperature resistant collecting tube 209, then pass through the interior of the high temperature resistant connecting tube 216, and then pass through the interior of the high temperature resistant cover 212, and then reach the interior of the three-way pipe 211, and finally be discharged from the gas outlet end of the three-way pipe 211, that is, to avoid heat accumulation in the interior of the high temperature resistant tube 204 and affect the sealing effect of the quartz tube. When the quartz tube completes the sealing operation, the gas supply to the flamethrower 107 is directly stopped at this time, so that the flamethrower 107 stops heating the quartz tube. Subsequently, the previously used method of discharging the internal heat of the high temperature resistant tube 204 can be used to perform air cooling on the sealed quartz tube, that is, to improve the processing efficiency of the quartz tube. When the quartz tube is heated and sealed due to When the quartz tube is broken and splashed due to product defects or operational errors, the cooperation of multiple high-temperature resistant open rings 208, high-temperature resistant plugs 206 and high-temperature resistant tubes 204 can prevent the broken and splashed quartz tube fragments from directly injuring the staff. At the same time, with the cooperation of the high-temperature resistant collecting tube 209, the broken and splashed quartz tube fragments inside the high-temperature resistant tube 204 can be collected. When it is necessary to release the gas, the venting valve 114 can be directly opened. When the quartz tube needs to be injected with inert gas after the vacuum operation is completed, the air inlet joint 112 is directly connected to the air outlet end of the pipe for supplying inert gas. Then, the air inlet joint 112, the control box 109, the sealing ring 118, the fixed tube 119 and the rotating end of the control box 109 are used in cooperation.Inert gas can be injected into the interior of the quartz tube.
