[0002] In today's era of rapid technological change, high-tech industries such as semiconductors, integrated circuits, optoelectronics, and new materials are developing at an unprecedented rate. Each technological breakthrough in these industries relies on the support of countless precision processes. High-purity and ultra-high-purity gases, as indispensable "blood" in these processes, are self-evident in their importance.

[0003] With the explosive growth of market demand for high-purity gases, how to safely and efficiently store and transport these gases has become a major challenge for the industry. In this context, high-purity grinding steel bottles have emerged as an indispensable part of the high-tech industry. The purpose of vacuumizing the steel bottle is to remove residual water, oxygen content, and dust particles on the inner surface of the steel bottle after cleaning and drying, thereby ensuring that the inner wall of the steel bottle is dry, oil-free, and free of other gas pollution. The quality of high-purity steel bottles depends on the quality of steel bottle cleaning and drying, valve leakage rate, cylinder wall roughness, and gas release, bore gas temperature, and vacuum process. Strict cleaning and drying process, reasonable air outlet position and flow guide, pure hot CO2 or N2 displacement, and heating of the steel bottle to increase the material temperature are the most effective methods to accelerate material surface outgassing and shorten the exhaust time. Therefore, the cleaned steel bottle is usually placed in an oven, heated while vacuumizing the steel bottle.

[0004] Currently, the existing technology usually places the cleaned and dried steel bottle in an oven. The steel bottle has a valve and a connecting pipe at the top, and the oven has an air exhaust pipe connected to a vacuum pump. The air exhaust pipe needs to be fixedly connected to the connecting pipe of the steel bottle, and then the valve of the steel bottle is opened to vacuumize the steel bottle by the vacuum pump. However, the air exhaust pipe in the oven is a messy hose that needs to be manually tightened and connected to the connecting pipe, and then the valve of the steel bottle needs to be manually opened. The operation is complicated, which can easily reduce the efficiency of the steel bottle vacuumizing. Therefore, it does not meet the existing needs, and thus we propose a high-purity steel bottle vacuumizing equipment. SUMMARY

[0042] Through the above technical scheme, the high-cleanliness steel cylinder vacuumizing equipment provided by the present application can be used as follows: Figure 4 As shown, the connecting pipe 113 is located at the left side of the pushing block 140, the steel cylinder body 110 is placed in the groove 121, as shown in Figure 8 Due to the weight of the steel cylinder body 110, the bottom plate 122 is pressed downward, so that the bottom plate 122 drives the first sliding rod 124 and the first wedge block 125 to move downward, through the cooperation of the two pairs of first wedge blocks 125 and second wedge blocks 126, the two second wedge blocks 126 drive the two second sliding rods 127 to move close to each other, so that the two second sliding rods 127 drive the two clamping pieces 128 to move close to each other to clamp and fix the steel cylinder body 110 on the base 120, the first motor 129 is started, and the base 120 is driven to rotate clockwise by the first motor 129, so that the base 120 drives the steel cylinder body 110 on it to rotate clockwise slowly; Subsequently, as shown in Figure 4 , Figure 11 and Figure 12 , the connecting pipe 113 rotates clockwise with the steel cylinder body 110, so that the connecting pipe 113 contacts the inclined surface of the pushing block 140, and the pushing block 140 is pushed backward, so that the second spring 141 is compressed, so that the pushing block 140 also drives the air suction pipe 130 and the sleeve 132 to move backward, and in the latter half of the backward movement of the air suction pipe 130, the protruding block 133 is also pressed on the damping pipe 134, so that the damping pipe 134 is deformed by being pressed, and the resistance of the movement of the air suction pipe 130 is increased, when the connecting pipe 113 completely passes the pushing block 140, as shown in Figure 4 , the connecting pipe 113 starts to press the end of the positioning rod 150, so that the positioning rod 150 drives the first electric contact piece 152 to move rightward and separate from the second electric contact piece 154, the circuit of the first motor 129 is disconnected, so that the first motor 129 stops rotating, so that the steel cylinder body 110 remains stationary, at this time, the center of the connecting pipe 113 and the center of the air suction pipe 130 are on the same horizontal line; Meanwhile, the air exhaust pipe 130 starts to move forward and reset under the action of the elastic force of the second spring 141. In the first half of the reset process, the protrusion 133 is pressed on the damping pipe 134, which increases the resistance of the air exhaust pipe 130 to reset, so that the air exhaust pipe 130 slowly resets, and the trumpet-shaped end of the air exhaust pipe 130 slowly sets on the connecting pipe 113. If there is a slight error in the angle of the connecting pipe 113 and the air exhaust pipe 130, the connecting pipe 113 will be in contact with the inner wall of the end of the air exhaust pipe 130, and a pushing force will be generated on the air exhaust pipe 130, so that the air exhaust pipe 130 will press the elastic ring 131, so that the angle of the air exhaust pipe 130 will be self-adapted and offset, so that the air exhaust pipe 130 can be accurately set on the connecting pipe 113. Then, in the second half of the reset process, the protrusion 133 is away from the damping pipe 134, which reduces the resistance of the air exhaust pipe 130 to continue to reset, so that the air exhaust pipe 130 quickly sets on the connecting pipe 113, thereby accurately and quickly connecting the connecting pipe 113 and the air exhaust pipe 130; Finally, the electric push rod 175 drives the rotating drum 160 and the pressing plate 180 to descend, so that the pressing plate 180 presses the air bag 181, and the air in the air bag 181 is pressed into the inflation cylinder 182, so that the inner surface of the inflation cylinder 182 is inflated inward and wrapped outside the connecting pipe 113, increasing the sealing between the air exhaust pipe 130 and the connecting pipe 113. Not only that, the clamping ring 170 is set outside the valve 112 and clamped with the valve 112. The second motor 174 drives the rotating drum 160 and the clamping ring 170 to rotate, so that the valve 112 rotates synchronously with the clamping ring 170, and the valve 112 is opened. Restarting the vacuum pump connected with the air exhaust pipe 130 can perform vacuumization on the steel cylinder body 110. In summary, the air exhaust pipe 130 and the connecting pipe 113 are quickly and efficiently fixed and connected, and the valve 112 of the steel cylinder body 110 is automatically opened, thereby improving the efficiency of vacuumizing the steel cylinder body 110.

[0043] It should be noted that the oven 100 heats the steel cylinder body 110, which is well known in the art and will not be described here. When the clamping ring 170 moves downward, if the groove on the clamping ring 170 is misaligned with the protrusion on the valve 112, the clamping ring 170 will be pressed on the valve 112, and the third spring 173 will be compressed. When the rotating drum 160 drives the clamping ring 170 to start rotating, the groove on the clamping ring 170 will first rotate to align with the protrusion on the valve 112, and the clamping ring 170 will be pressed downward under the action of the elastic force of the third spring 173, so that the clamping ring 170 can be clamped with the valve 112. After the vacuum is completed, first, the output shaft of the second motor 174 is reversed, so that the electric push rod 175 drives the rotating drum 160 and the clasp ring 170 to reverse, so that the clasp ring 170 drives the valve 112 to rotate reversely to close the valve 112, then the rotating drum 160 drives the clasp ring 170 and the pressing plate 180 to move up and reset, releasing the pressing plate 180 from pressing the air bag 181, the air bag 181 rebounds to suck the air in the inflation cylinder 182 back into the air bag 181, so that the inflation cylinder 182 recovers to release the sealing effect on the connecting pipe 113, finally holding the pull rod 137 to pull the suction pipe 130 backward, so that the suction pipe 130 and the connecting pipe 113 are separated; When the steel cylinder body 110 is placed on the bottom plate 122, the bottom plate 122 is pressed down, so that the first spring 123 is compressed, the bottom plate 122 presses down the first sliding rod 124 and the first wedge block 125, and the first wedge block 125 is used in cooperation with the second wedge block 126, so that the two second wedge blocks 126 are close to each other, when the steel cylinder body 110 is removed, the bottom plate 122 is reset by the elastic force of the first spring 123, and then the first wedge block 125 and the second wedge block 126 are used in cooperation, so that the two first wedge blocks 125 drive the two second wedge blocks 126 to reset away, so that the two second wedge blocks 126 drive the two second sliding rods 127 and the two clamping pieces 128 to reset away from each other.
