Description

Technical Field

[0001] This invention relates to the field of distillation column technology, and more particularly to a distillation column with high safety. Background Technology

[0002] A distillation column is a chemical engineering device used to separate substances with different boiling points, commonly used in industries such as chemical, petroleum, pharmaceutical, and food processing. It utilizes the difference in boiling points of substances during the distillation process to separate components in a mixture into multiple fractions of higher purity. Currently, some horizontally installed distillation columns are not very high at the top, requiring climbing for maintenance. Climbing methods include using ladders or the climbing mechanisms built into some distillation columns. Traditional ladders usually rely on the ground or the column itself for support, but uneven ground or improper placement of the ladder can cause instability and tipping, increasing the risk of accidents. Furthermore, some distillation columns are equipped with U-shaped, linearly arranged ladders for easy climbing. These ladders allow unauthorized personnel to climb freely, and untrained personnel who do not use the ladders correctly, or those lacking appropriate safety precautions, are prone to falls. Summary of the Invention

[0003] The purpose of this invention is to address the current methods of climbing on horizontally installed distillation columns, which include using ladders or climbing mechanisms built into the columns. However, traditional ladders are unstable and can tip over, increasing the risk of accidents. Furthermore, some distillation columns use U-shaped, linearly arranged ladders for easy climbing, which allows unauthorized individuals to easily climb, increasing the risk of falls. This invention proposes a highly safe distillation column.

[0004] The technical solution of the present invention: A highly secure distillation column, comprising a distillation column body, and further comprising: a ladder mechanism disposed on the distillation column body and conforming to the outer wall of the distillation column body when closed; a locking mechanism, installed on the outer wall of the distillation column body to allow the ladder mechanism to open upon authorization; multiple pairs of first rotating seats, connecting rotating rods and second rotating seats supporting the opening of the ladder mechanism; and a locking mechanism disposed on one pair of the connecting rotating rods to prevent the opened ladder mechanism from rotating in the reverse direction.

[0005] Optionally, the climbing mechanism includes an arc-shaped climbing ladder, with a pair of support columns fixedly connected to both ends of the arc-shaped climbing ladder, an arc-shaped handrail fixedly connected to the middle of the support columns, multiple foot slots arranged in a circular array on the arc-shaped climbing ladder, multiple filling blocks that fit into the corresponding foot slots fixedly connected to the outer wall of the distillation column body, and a pair of handrail top frames that lock into the corresponding support columns fixedly connected to the top of the distillation column body.

[0006] Optionally, the top frame of the handrail is provided with an arc-shaped groove for the support column to be locked in place after rotation.

[0007] Optionally, the locking mechanism includes a U-shaped block fixedly connected to the outer wall of the distillation column body for the arc-shaped handrail to be inserted into. The end of the U-shaped block is provided with a pair of padlock holes, and a padlock lock is hung inside the padlock holes to lock the arc-shaped handrail out of the U-shaped block.

[0008] Optionally, the locking mechanism includes a central sleeve fixedly fitted in the middle of the connecting rod, a pair of limiting strips fixedly connected to both ends of the connecting rod, and a locking sleeve slidably connected to both ends of the connecting rod to lock the corresponding first rotating seat or second rotating seat so that it cannot rotate. Each locking sleeve is provided with a pair of protruding sleeves that lock the limiting strips.

[0009] Optionally, the locking mechanism further includes return springs sleeved at both ends of the connecting rod, one end of each return spring being fixedly connected to the central sleeve, and the other end of each return spring being fixedly connected to the corresponding locking sleeve.

[0010] Optionally, a pair of pinch blocks are fixedly connected to the outer wall of the end of the locking sleeve near the center sleeve.

[0011] Optionally, anti-slip pads are fixedly connected to the inside of each foot slot.

[0012] Optionally, the top of the distillation column body is provided with a first connection port and a second connection port, and the bottom of the distillation column body is fixedly connected with a pair of support bases for support.

[0013] In summary, this application includes at least one of the following beneficial technical effects:

[0014] This invention, through the design of a climbing mechanism, locking mechanism, first rotating seat, connecting rod, and second rotating seat, ensures that only those holding the key to the padlock can use the climbing mechanism. This effectively prevents unauthorized personnel from entering dangerous areas such as the distillation tower. Furthermore, the key management and authorization mechanism ensures that only trained personnel with professional knowledge can enter the climbing area. This helps clarify safety management responsibilities and prevent safety accidents caused by unqualified personnel entering the equipment area.

[0015] Furthermore, the present invention utilizes the cooperation of structures such as a central retaining sleeve, a limiting retaining strip, a locking retaining sleeve, a protruding retaining sleeve, a return spring, and a locking mechanism, so that when the user opens the ladder mechanism, the first rotating seat, the connecting rod, and the second rotating seat will be locked by the locking mechanism, preventing the first rotating seat, the connecting rod, and the second rotating seat from rotating during use, and avoiding the ladder mechanism from suddenly closing during use and causing damage to the user.

[0030] Example

[0031] like Figures 1 to 7As shown, this invention proposes a highly safe distillation column, comprising a distillation column body 1. The top of the distillation column body 1 is provided with a first connection port 11 and a second connection port 12. The first connection port 11 and the second connection port 12 on the distillation column body 1 are interface components used to connect different pipes or other equipment. They are typically installed in different parts of the distillation column, serving to transfer materials, gases, liquids, or heat. A pair of support bases 13 are fixedly connected to the bottom of the distillation column body 1. The support bases 13 are structural parts that support the entire column body, usually located at the bottom of the column, bearing the weight of the distillation column and ensuring its stability. The bases not only physically support the column body but also cooperate with other equipment (such as a bottom liquid discharge system, pipe connections, etc.) to ensure the safe and efficient operation of the entire system. It also includes: a ladder mechanism installed on the distillation column body 1 and attached to the outer wall of the distillation column body 1 after closing; a locking mechanism installed on the outer wall of the distillation column body 1 so that the ladder mechanism can be opened after authorization; multiple pairs of first rotating seats 23, connecting rotating rods 24 and second rotating seats 25 supporting the opening of the ladder mechanism; and a locking mechanism installed on one of the pairs of connecting rotating rods 24 so that the opened ladder mechanism cannot rotate in reverse. The locking mechanism prevents the opened ladder mechanism from closing suddenly, which ensures that the ladder always remains open during use, so that users can go up and down with peace of mind without worrying that the ladder will suddenly close, thus avoiding possible injury or accidents.

[0032] Furthermore, the climbing mechanism includes an arc-shaped climbing ladder 2, with a pair of support columns 26 fixedly connected to both ends of the arc-shaped climbing ladder 2. An arc-shaped handrail 27 is fixedly connected to the middle of the support columns 26. The arc-shaped handrail 27 provides users with additional support and grip points, effectively preventing people from losing their balance or slipping when climbing up or down the arc-shaped climbing ladder 2. Especially in high or uneven environments, the arc-shaped handrail 27 provides users with better stability and reduces the risk of falling. The arc-shaped climbing ladder 2 has multiple foot slots 21 arranged in a circumferential array. Anti-slip pads 22 are fixedly connected inside each foot slot 21. The anti-slip pads 22 are usually made of frictional materials, such as rubber, silicone, or polyurethane. These materials can increase the friction between the sole of the foot and the foot slot 21 when stepping on them, thereby reducing the risk of slipping and falling. The outer wall of the distillation column body 1 is fixedly connected with multiple filling blocks 5 that engage with corresponding foot slots 21. These filling blocks 5 ensure that when the curved ladder 2 is closed, there are no foot slots 21 for anyone to step on, preventing its use by others. The top of the distillation column body 1 is fixedly connected with a pair of handrail brackets 3 that engage with corresponding support columns 26. These handrail brackets 3 serve the same function as the curved handrail 27. The handrail brackets 3 have curved slots 31 that engage with the rotated support columns 26, securing the top of the open curved ladder 2 and ensuring stable use when the top of the ladder 2 is open.

[0033] The locking mechanism includes a U-shaped block 4 fixedly connected to the outer wall of the distillation column body 1 for the arc-shaped support bar 27 to be inserted into. A pair of padlock holes 41 are provided at the end of the U-shaped block 4. A padlock 42 is hung inside the padlock hole 41 to lock the arc-shaped support bar 27 out of the U-shaped block 4. The padlock 42 is a common type of lock, usually consisting of a detachable lock body and a hook, used to protect the safety of items or areas.

[0034] Secondly, the locking mechanism includes a central sleeve 241 fixedly fitted in the middle of the connecting rod 24. A pair of limiting strips 242 are fixedly connected to both ends of the connecting rod 24. Locking sleeves 243 are slidably connected to both ends of the connecting rod 24, locking the corresponding first rotating seat 23 or second rotating seat 25 and preventing it from rotating. A pair of pinch blocks 245 are fixedly connected to the outer wall of the locking sleeves 243 near the central sleeve 241. The pinch blocks 245 provide a point of force when the hand slides the locking sleeves 243, thus facilitating operation. Each locking sleeve 243 is provided with a pair of protruding sleeves 244 that lock the limiting strips 242. The limiting strips 242 lock the protruding sleeves 244, ensuring that the locking sleeves 243 do not rotate when sliding on the connecting rod 24. Meanwhile, the protruding sleeve 244 can also hold the shaft ends on the first rotating seat 23 and the second rotating seat 25, and the shaft ends on the first rotating seat 23 and the second rotating seat 25 are on the same axis as the connecting rod 24.

[0035] Furthermore, the locking mechanism also includes return springs 246 sleeved at both ends of the connecting rotating rod 24. The return springs 246 cause the opened ladder mechanism to drive the first rotating seat 23, the connecting rotating rod 24, and the second rotating seat 25 to... Figure 7 In this state, the locking sleeve 243 will lock the corresponding first rotating seat 23 and second rotating seat 25, thus preventing the climbing mechanism from closing. One end of the return spring 246 is fixedly connected to the central sleeve 241, and the other end of the return spring 246 is fixedly connected to the corresponding locking sleeve 243.

[0036] In this embodiment, when using a distillation column that is easy to maintain, such as Figure 1As shown, when staff need to climb onto the distillation column body 1 for inspection or maintenance, they simply need to unlock the padlock 42 on the U-shaped block 4, allowing the padlock 42 to be removed from the pair of padlock holes 41. Then, the curved ladder 2 is pulled, causing it to rotate via the support of the first rotating seat 23, the connecting rod 24, and the second rotating seat 25. This continues until the top of the curved ladder 2 moves a pair of support columns 26 into the curved slots 31 on the corresponding handrail top frame 3. At this point, the locking sleeve 243, through the elastic thrust of the corresponding return spring 246, locks the corresponding first rotating seat 23 and second rotating seat 25, preventing the connecting rod 24 from rotating with the first rotating seat 23 and second rotating seat 25. This restricts the movement of the curved ladder 2 towards the distillation column body 1, allowing the staff to insert their feet into the foot slots 21 and climb step by step to reach the top of the distillation column body 1. After using the curved ladder 2, simply stand in front of it with your hands clasped, placing your hands on a pair of connecting rods 24 with central retaining sleeves 241. Then, simultaneously squeeze a pair of gripping blocks 245 towards the central retaining sleeves 241. The gripping blocks 245 will move one end of the corresponding locking sleeve 243, causing it to disengage from the corresponding first rotating seat 23 and second rotating seat 25. This allows the connecting rods 24 to rotate between the connecting ends of the first rotating seat 23 and the second rotating seat 25, enabling the curved ladder 2 to move closer to the distillation column body 1, and ultimately rotate the curved ladder 2 to... Figure 1 As shown. Until the foot slots 21 on the curved ladder 2 are engaged by the corresponding full-filling blocks 5, the curved ladder 2 will cause its side curved handrails 27 to re-engage into the U-shaped blocks 4. Finally, the padlock 42 is hung on the padlock hole 41 and locked.

[0037] The preferred embodiments of the present invention described above are merely illustrative of the invention. These preferred embodiments do not exhaustively describe all details, nor do they limit the invention to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the invention, thereby enabling those skilled in the art to better understand and utilize the invention. The invention is limited only by the claims and their full scope and equivalents.
