A double-cylinder special gas cabinet

Abstract

The present invention relates to the technical field of special gas cabinets, and specifically to a double-cylinder special gas cabinet, which includes a cabinet body, a protective shell, and two cylinder bodies arranged inside the cabinet body. An inclined disk is arranged inside the cabinet. When the push rod is pushed for the first-stage movement, the inclined disk can be driven to drive the cylinder body to turn over. When the push rod is pushed for the second-stage movement, the bottle head valve and the connection valve can be opened or closed synchronously. The push rod is used for the third-stage movement to first open and then close the exhaust valve connected to the pipeline system. For this double-cylinder special gas cabinet, the device adopts a mechanical structure in which a lever-type control mechanism and a control turning component cooperate. By operating the push rod to drive the control turning component, the cylinder on the inclined positioning disk can be transferred to the inside of the cabinet body, thus realizing the full-process lifting-free operation of the installation and disassembly of the cylinder. Even when the automatic control system fails, the exhaust operation can still be carried out safely and effectively manually.

Description

Technical Field

[0001] The present invention relates to the technical field of special gas cabinets, and more particularly to a double-cylinder special gas cabinet. Background Art

[0002] A double-cylinder special gas cabinet is an industrial device for safely storing and supplying special gases, mainly serving fields with extremely high requirements for gas purity, stability, and safety. Its core design adopts a "main + standby" double-cylinder configuration, combined with an automatic switching system to ensure the continuity of gas supply.

[0003] When replacing cylinders in traditional double-cylinder special gas cabinets, the operation process is relatively complex. Specifically, the operator needs to first close the valves and bleed valves on the cylinders, then remove the hoses connected to the cylinders. To ensure that no gas remains in the pipeline system, the operator also needs to completely empty the gas in the pipeline through the exhaust valve. After completing this series of steps, the operator can manually remove the cylinder. As for installing a new cylinder, the operator needs to first reconnect the hoses and then sequentially open the valves and bleed valves on the cylinder in a set order.

[0004] However, in practical applications, it has been found that this cylinder replacement method is not only time-consuming and laborious, especially in the disassembly and assembly of cylinders, but also due to the large number of valves involved, it further exacerbates the complexity of the operation process. Therefore, we propose a double-cylinder special gas cabinet. Summary of the Invention

By the movement of the rack three 102, the inclined rod 103 is driven to move. Since the top end of the spline sleeve two 108 is an inclined surface, a plurality of limiting rods 104 will be driven to enter the bottle head valve 8, thereby driving the bottle head valve 8 to rotate.

[0051] The linkage unit two 7 includes an air cylinder two 72 disposed on the side of the cabinet 1. An inflatable telescopic rod two 73 is disposed on the inner wall of the cabinet 1. A connecting pipe 71 is disposed between the inflatable telescopic rod two 73 and the air cylinder two 72. The connecting pipe 71 is connected to the middle part of the air cylinder two 72. A gear two 75 is sleeved on the exhaust valve 15. A rack two 74 is disposed on the inflatable telescopic rod two 73. The rack two 74 meshes with the gear two 75. Since the connecting pipe 71 is at the middle part of the air cylinder two 72, pulling the air cylinder two 72 can drive the inflatable telescopic rod two 73 to perform a reciprocating motion.

[0052] The control flipping assembly 11 includes a plurality of straight plates 111 disposed at the top end of the inclined disk 5. An arc-shaped groove plate 112 is disposed between the plurality of straight plates 111. An arc-shaped plate 113 is movably disposed on the inner wall of each of the plurality of arc-shaped groove plates 112. Each of the plurality of arc-shaped plates 113 is movably disposed on the outer surface of the steel cylinder body 4. Two support plates 114 are disposed at the bottom of the inner wall of the cabinet 1. A flipping shaft 115 is rotatably disposed between the two support plates 114. The inclined disk 5 is sleeved on the outer surface of the flipping shaft 115. The end of the flipping shaft 115 penetrates through the support plate 114 and the cabinet 1, and a gear four 116 is sleeved thereon. A rack four 117 is disposed on the side of the cabinet 1. The rack four 117 meshes with the gear four 116. Pulling the arc-shaped plate 113 out of the arc-shaped groove plate 112 can limit the steel cylinder body 4 in this way.

[0053] Three chutes 119 are formed at the top of the inner wall of the protective shell 2. Two U-shaped grooves 120 are disposed between the three chutes 119. A slide bar 123 is movably disposed in the three chutes 119 and the two U-shaped grooves 120. The three chutes 119 and the two U-shaped grooves 120 communicate with each other.

[0054] A slotted plate 122 is provided at the bottom end of the sliding rod 123. A sleeve plate 121 is sleeved on the outer surface of the slotted plate 122. The bottom end of the shift lever 3 penetrates through the protective shell 2 and is arranged at the top of the sleeve plate 121. A pointed plate 118 is arranged on the side of the fourth rack 117. L-shaped pointed rods 124 are provided at the output ends of the first air cylinder 61 and the second air cylinder 72. And the slotted plate 122 is movably arranged on the pointed plate 118 and the two L-shaped pointed rods 124. When the sliding rod 123 enters the sliding groove 119, the slotted plate 122 will enter the pointed plate 118 or the L-shaped pointed rod 124.

[0055] When using this device, first, the cylinder body 4 needs to be installed in the cabinet body 1. At this time, it will push the shift lever 3 to move on the protective shell 2. The shift lever 3 will cause the slotted plate 122 to enter the pointed plate 118, thereby driving the fourth rack 117 to move. The fourth rack 117 drives the fourth gear 116 to rotate. The fourth gear 116 drives the turning shaft 115 to rotate, and will drive the inclined disk 5 to rotate. At this time, it can drive the cylinder body 4 to enter the inclined disk 5. Pull the arc plate 113 to fit on the outer surface of the cylinder body 4 to complete. At this time, push the shift lever 3 again, so that the shift lever 3 drives the sleeve plate 121 at the end face to move. The sleeve plate 121 drives the slotted plate 122 to move. At this time, the sliding rod 123 will enter the U-shaped groove 120 from the sliding groove 119, resulting in the slotted plate 122 moving away from the pointed plate 118 and entering the L-shaped pointed rod 124 at the connecting pipe 71. However, since the inlet valve 67 and the cylinder head valve 8 are not opened, there is no impact;

[0056] At this time, the slotted plate 122 will enter the L-shaped pointed rod 124 of the first air cylinder 61, and can drive the L-shaped pointed rod 124 to move. The first air cylinder 61 will squeeze the gas into the main hose 62. The gas in the main hose 62 enters the three-way plate 63 and enters the second branch pipe 65 and the first branch pipe 64 respectively through the three-way plate 63. When entering the first branch pipe 64, it will enter the first inflatable telescopic rod 66, and then drive the first rack 615 to move. The first rack 615 drives the first gear 68 to rotate. The first gear 68 drives the internal block 613 to move. The block 613 is stuck on the first spline shaft 611. Therefore, it will drive the inlet valve 67 to open. At this time, when manual use is required, only need to press the first spline sleeve 69 and the first spring 610. The inclined surface at the end face of the first spline sleeve 69 squeezes the inclined surface of the straight groove 612. For this reason, the block 613 will enter the straight groove 612 and simultaneously squeeze the second spring 614. For this reason, the first spline sleeve 69 can drive the first spline shaft 611 to rotate. Loosing the first spline sleeve 69 will reset under the action of the second spring 614 and the first spring 610;

[0057] At this time, the gas in the second branch pipe 65 will enter the inflatable telescopic rod three 101. The inflatable telescopic rod three 101 will drive the rack three 102 and the inclined rod 103 to move simultaneously. The movement of the rack three 102 will drive the gear three 107 to rotate, thereby driving the spline shaft two 106 in the gear three 107 to rotate. At this time, the inclined rod 103 will squeeze the inclined surface of the spline sleeve two 108, causing the spline sleeve two 108 to drive the limit rod 104 into the bottle head valve 8, and at the same time pulling the tension spring 105 to deform.

[0058] When it is necessary to disassemble the cylinder body 4 for replacement, it is necessary to pull the lever 3 in the reverse direction. Then the intake valve 67 will reset, and the bottle head valve 8 will also reset. The spline sleeve two 108 will reset under the action of the tension spring 105. At this time, the slotted plate 122 will drive the output end of the air cylinder two 72 to move, so that the air cylinder two 72 will transport the gas into the connecting pipe 71, causing the inflatable telescopic rod two 73 to drive the rack two 74 to reciprocate, so as to open and close the exhaust valve 15, complete the exhaust of the pipeline system, and finally the cylinder body 4 can be turned out again through the inclined plate 5.

[0059] Embodiment 2: Please refer to Figures 11-12 , the present invention provides a technical solution: A plurality of arc-shaped rubber sheets 12 are arranged on the inner side of the arc-shaped plate 113, and ball bearings 13 are movably embedded on the outer surfaces of the upper and lower ends of the arc-shaped plate 113. The ball bearings 13 are movably arranged on the inner wall of the arc-shaped groove plate 112. The provided rubber sheets 12 have a certain anti-slip effect, which can make the arc-shaped plate 113 better fit on the cylinder body 4, and the setting of the ball bearings 13 can make it smoother when pulling the arc-shaped plate 113.
