Description

Technical Field

[0001] The present invention relates to the technical field of distillation towers, and in particular to a distillation tower with high safety. Background Art

[0002] A distillation tower is a chemical engineering equipment used to separate substances with different boiling points. It is commonly used in industries such as chemistry, petroleum, pharmaceuticals, and food processing. It uses the difference in boiling points of substances through the distillation process to separate the components in a mixture into multiple parts with higher purity. At present, the top height of some horizontally installed distillation towers is not too high, and it is usually necessary to climb up to it when maintaining it. The climbing methods include using ladders or climbing mechanisms that come with some distillation towers. Traditional ladders usually need to rely on the ground or the tower body for support, but sometimes the ground is uneven or the ladder is improperly placed, which will cause the ladder to be unstable and fall, increasing the risk of accidents. At the same time, some distillation towers are equipped with U-shaped ladders that are easy to climb and are arranged linearly. This ladder allows any unauthorized person to climb at will, and when untrained personnel fail to use the climbing ladder correctly, or due to the lack of appropriate safety protection measures, it is easy to fall. Summary of the invention

[0003] The purpose of the present invention is to solve the problem that some distillation towers installed horizontally currently have climbing methods such as using ladders or climbing mechanisms built into some distillation towers. When traditional ladders are unstable and fall down, the risk of accidents will increase. At the same time, some distillation towers are provided with U-shaped ladders that are easy to climb and are arranged linearly. Such ladders allow any unauthorized person to climb at will, which is prone to falling accidents. A distillation tower with high safety is proposed.

[0004] The technical solution of the present invention is as follows: a distillation tower with high safety comprises a distillation tower body, and also comprises: a ladder mechanism arranged on the distillation tower body and fitted to the outer wall of the distillation tower body after being closed; a locking mechanism installed on the outer wall of the distillation tower body so that the ladder mechanism can be opened after authorization; a plurality of pairs of first rotating seats, connecting rotating rods and second rotating seats supporting the ladder mechanism to rotate and open; a locking mechanism arranged on one pair of the connecting rotating rods so that the ladder mechanism cannot rotate reversely after being opened.

[0005] Optionally, the ladder mechanism includes an arc-shaped ladder, both side ends of the arc-shaped ladder are fixedly connected to a pair of support columns, the middle part of the support column is fixedly connected to an arc-shaped handrail, the arc-shaped ladder is provided with a plurality of foot slots distributed in a circular array, the outer wall of the distillation tower body is fixedly connected to a plurality of full blocks that are inserted into corresponding foot slots, and the top of the distillation tower body is fixedly connected to a pair of handrail top frames that clamp the corresponding support columns.

[0006] Optionally, the armrest top frame is provided with an arc-shaped slot for the rotating support column to be clamped.

[0007] Optionally, the locking mechanism includes a U-shaped block fixedly connected to the outer wall of the distillation tower body for the arc-shaped support rod to be inserted into, a pair of padlock holes are opened at the end of the U-shaped block, and a padlock is hung inside the padlock hole to clamp the arc-shaped support rod out of the U-shaped block.

[0008] Optionally, the locking mechanism includes a center sleeve fixedly mounted on the middle part of the connecting rotating rod, and both ends of the connecting rotating rod are fixedly connected to a pair of limit strips, and both ends of the connecting rotating rod are slidably connected to locking sleeves that clamp the corresponding first rotating seat or the second rotating seat to prevent it from rotating, and the locking sleeves are provided with a pair of protruding sleeves that clamp the limit strips.

[0009] Optionally, the locking mechanism further includes a return spring sleeved on both ends of the connecting rotating rod, one end of the return spring is fixedly connected to the center sleeve, and the other end of the return spring is 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 close to the center sleeve.

[0030] Example

[0031] like Figures 1 to 7As shown, a distillation tower with high safety proposed by the present invention includes a distillation tower body 1, and a first connection port 11 and a second connection port 12 are provided on the top of the distillation tower body 1. The first connection port 11 and the second connection port 12 on the distillation tower body 1 refer to interface components for connecting different pipelines or other equipment. They are usually installed at different parts of the distillation tower to play the role of transmitting materials, gases, liquids or heat. A pair of support bases 13 for support are fixedly connected to the bottom of the distillation tower body 1. The support base 13 is a structural part that supports the entire tower body, which is usually located at the bottom of the tower, bears the weight of the distillation tower and ensures the stability of the tower body. The base is not only the basis for physically supporting the tower body, but also cooperates with other equipment (such as the liquid discharge system at the bottom of the tower, pipeline connection, etc.) to ensure the safety and efficient operation of the entire system. It also includes: a ladder mechanism arranged on the distillation tower body 1 and fitted to the outer wall of the distillation tower body 1 after being closed; a locking mechanism, installed on the outer wall of the distillation tower body 1 so that the ladder mechanism can be opened after authorization; a plurality of pairs of first rotating seats 23, connecting rotating rods 24 and second rotating seats 25 that support the ladder mechanism to rotate and open; a locking mechanism, arranged on one pair of connecting rotating rods 24 so that the ladder mechanism cannot rotate reversely after being opened, and the locking mechanism prevents the opened ladder mechanism from being suddenly closed, which ensures that the ladder always remains in an open state during use, and the user can go up and down with peace of mind without having to worry about the ladder suddenly closing, thereby avoiding possible injuries or accidents caused by this.

[0032] Furthermore, the ladder mechanism includes an arc-shaped ladder 2, and a pair of support columns 26 are fixedly connected to both ends of the arc-shaped ladder 2, and an arc-shaped handrail 27 is fixedly connected to the middle of the support column 26. The arc-shaped handrail 27 provides additional support and gripping points for users, and can effectively prevent people from losing balance or slipping when going up and down the arc-shaped ladder 2. Especially in high altitude or uneven environments, the arc-shaped handrail 27 can provide users with better stability and reduce the risk of falling. The arc-shaped ladder 2 is provided with a plurality of foot slots 21 distributed in a circular array, and the inside of the foot slots 21 are fixedly connected with anti-skid pads 22. The anti-skid pads 22 are usually made of materials with friction, such as rubber, silicone or polyurethane, etc. These materials can increase the friction between the sole of the foot and the foot slot 21 when stepping, thereby reducing the risk of sliding and slipping. The outer wall of the distillation tower body 1 is fixedly connected with a plurality of full blocks 5 that are inserted into the corresponding foot slots 21. The full blocks 5 are used to prevent the arc ladder 2 from having foot slots 21 for people to step on after it is closed, so that the arc ladder 2 cannot be used by others when it is closed. The top of the distillation tower body 1 is fixedly connected with a pair of handrail top frames 3 that clamp the corresponding support columns 26. The handrail top frames 3 have the same function as the arc handrail 27. The handrail top frames 3 are provided with arc-shaped slots 31 for the rotating support columns 26 to clamp. The arc-shaped slots 31 clamp the top of the opened arc ladder 2, thereby ensuring that the top of the arc ladder 2 is stable for use after it is opened.

[0033] Among them, the locking mechanism includes a U-shaped block 4 fixedly connected to the outer wall of the distillation tower body 1 for the arc-shaped support rod 27 to be inserted into, a pair of padlock holes 41 are opened at the end of the U-shaped block 4, and a padlock lock 42 is hung inside the padlock hole 41 to clamp the arc-shaped support rod 27 out of the U-shaped block 4. The padlock lock 42 is a common lock, usually composed of a detachable lock body and a hook, and is used to protect the safety of objects or areas.

[0034] Secondly, the locking mechanism includes a central clamping sleeve 241 fixedly sleeved in the middle of the connecting rotating rod 24, a pair of limit clamping strips 242 fixedly connected at both ends of the connecting rotating rod 24, a locking clamping sleeve 243 slidably connected at both ends of the connecting rotating rod 24 to clamp the corresponding first rotating seat 23 or the second rotating seat 25 so that it cannot rotate, and a pair of pinching blocks 245 are fixedly connected to the outer wall of the end of the locking clamping sleeve 243 close to the central clamping sleeve 241, and the pinching blocks 245 provide a force point when the hand slides the locking clamping sleeve 243, so as to facilitate the manipulation of the locking clamping sleeve 243. A pair of protruding clamping sleeves 244 that clamp the limit clamping strip 242 are provided on the locking clamping sleeve 243. The limit clamping strip 242 clamps the protruding clamping sleeve 244 to ensure that the locking clamping sleeve 243 does not rotate when sliding on the connecting rotating rod 24. At the same time, the protruding sleeve 244 can still clamp 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 and the connecting rotating rod 24 are located on the same axis.

[0035] Furthermore, the locking mechanism also includes a return spring 246 mounted on both ends of the connecting rod 24. The return spring 246 enables the ladder mechanism to drive the first rotating seat 23, the connecting rod 24 and the second rotating seat 25 to present Figure 7 The locking sleeve 243 at this time will clamp the corresponding first rotating seat 23 and the second rotating seat 25, so that the ladder mechanism cannot be closed. One end of the return spring 246 is fixedly connected to the center 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 a distillation tower that is easy to maintain is used, such as Figure 1As shown, when the staff needs to climb onto the distillation tower body 1 for inspection or maintenance, they only need to open the padlock 42 on the U-shaped block 4 so that the padlock 42 is taken out from the pair of padlock holes 41. After that, the arc ladder 2 is pulled again, and the arc ladder 2 is rotated by supporting the first rotating seat 23, the connecting rotating rod 24 and the second rotating seat 25. Until the top of the arc ladder 2 drives the pair of supporting columns 26 to move into the arc slot 31 on the corresponding handrail top frame 3, the locking sleeve 243 at this time is locked by the elastic thrust of the corresponding return spring 246, so that the locking sleeve 243 is locked to the corresponding first rotating seat 23 and the second rotating seat 25, so that the connecting rotating rod 24 and the first rotating seat 23 and the second rotating seat 25 cannot rotate, thereby limiting the movement of the arc ladder 2 to the distillation tower body 1, and finally the staff can insert their feet into the foot slot 21 and climb step by step to reach the top of the distillation tower body 1. After the arc ladder 2 is used, one only needs to stand in front of the arc ladder 2 with both hands in a hugging state, so that the left and right hands are placed on a pair of connecting rods 24 with a central clamping sleeve 241, and then both hands simultaneously pinch a pair of pinching blocks 245 in the direction of the central clamping sleeve 241, and the pinching blocks 245 drive one end of the corresponding locking clamping sleeve 243, and at the same time, the locking clamping sleeve 243 is disengaged from the corresponding first rotating seat 23 and the second rotating seat 25. In this way, the connecting rod 24 and the connecting ends of the first rotating seat 23 and the second rotating seat 25 can be rotated, and the arc ladder 2 can be moved in the direction close to the distillation tower body 1, and then the arc ladder 2 is rotated to the direction such as Figure 1 Until the foot slot 21 on the curved ladder 2 is clamped by the corresponding full clamping block 5, the curved ladder 2 drives the curved handrail 27 on its side to be clamped into the U-shaped block 4 again, and finally the padlock 42 is hung on the padlock hole 41 and locked.
