Description

Technical Field

[0001] This utility model relates to the technical field of pipeline interface support mechanism and distillation column, and in particular to a pipeline interface support mechanism and distillation column. Background Technology

[0002] Distillation is an extremely important separation process in many industrial fields such as chemical, petrochemical, and pharmaceutical industries. As the core equipment of distillation, the stable operation of the distillation column is of vital importance to product quality, production efficiency, and production safety. The feed pipe is the key channel for transporting raw materials into the distillation column. In order to improve the stability of the feed pipe, a pipe interface support mechanism is usually set up to support, fix, and protect the distillation column and the interface connected to it.

[0003] Existing feed pipe interface support mechanisms typically use fixed-structure brackets. However, due to the presence of impurities or solid particles in the raw materials, or the polymerization or crystallization reactions that occur in the raw materials themselves under certain circumstances, the feed pipe is prone to blockage. Regular disassembly and cleaning are required. However, due to the fixed structure of the bracket, disassembling the feed pipe requires completely removing the bracket or operating with difficulty under the constraints of the bracket, which greatly increases the difficulty and time cost of disassembling the feed pipe. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a pipeline interface support mechanism and a distillation tower.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a pipe interface support mechanism and a distillation column, comprising a distillation column body, a feed pipe fixedly connected to the distillation column body, a base fixedly connected to the distillation column body, a support structure provided on the feed pipe, the support structure mainly consisting of a lower sleeve clamp, an upper sleeve clamp provided on the lower sleeve clamp, a first bracket fixedly connected to the lower sleeve clamp, a second bracket rotatably connected to the first bracket via a hinge, gaskets fixedly connected to both the lower and upper sleeve clamps, a rectangular groove provided on the second bracket, a connecting block slidably connected in the rectangular groove, and a connecting groove provided on the first bracket.

[0006] The aforementioned components achieve the following effects: the lower and upper clamps are respectively positioned above and below the connection between the distillation column body and the feed pipe, and then secured with bolts and connecting lugs. The gasket is made of polytetrafluoroethylene (PTFE), which reduces damage to the pipe's anti-corrosion layer during clamping. The base is welded to the reinforcing ring of the distillation column body, and the second support is installed on the base. The first and second supports provide support for the feed pipe. When disassembling and cleaning the feed pipe is required, the upper clamp is removed, and the first support is rotated to fold the first and second supports together, preventing interference with operations. After the operation is completed, the first support is rotated back to its original position, and then the sliding connecting block is slid into the connecting groove to limit the first support. This avoids the situation where, due to the fixed structure of the support, disassembling the feed pipe requires complete removal of the support or difficult operation under the restriction of the support, which greatly increases the difficulty and time cost of disassembling the feed pipe.

[0007] Preferably, the first bracket has a slot, a first spring is fixedly connected in the slot, a damping rod is fixedly connected in the slot, and the first spring is sleeved on the damping rod.

[0008] The effect achieved by the above components is as follows: when the medium impacts the feed pipe, the impact force acts on the first spring, causing it to deform and absorb some of the energy. Then it rebounds and resets, releasing the absorbed energy. At this time, the damping rod converts the energy into heat energy through friction on the inner wall, thereby reducing the impact and amplitude.

[0009] Preferably, a slide rod is slidably inserted into the second bracket, and the slide rod is fixedly connected to the connecting block.

[0010] The effect achieved by the above components is that the operator can move the connecting block by sliding the slide bar.

[0011] Preferably, a second spring is fixedly connected to the connecting block, and one end of the second spring is fixedly connected to the inner wall of the rectangular groove.

[0012] The effect achieved by the above components is that when the connecting block is inserted into the connecting groove, the second spring is in a contracted state, so the rebound force of the second spring acts on the connecting block, making the limit more stable.

[0013] Preferably, the second bracket is provided with an installation structure, which is mainly composed of an installation block. The installation block is fixedly connected to the second bracket, and the base is provided with an installation groove.

[0014] The aforementioned components achieve the following effects: by inserting the mounting block into the mounting slot, the second bracket can be quickly installed; conversely, it can be easily disassembled.

[0015] Preferably, sliding grooves are provided on the inner walls of both sides of the mounting groove, and a locking block is slidably connected in the sliding groove. The mounting block has locking slots on both sides.

[0016] The effect achieved by the above components is that the sliding block can be locked into the corresponding slot, thereby limiting the position of the mounting block.

[0017] Preferably, the sliding block is engaged in the corresponding slot to limit the position of the mounting block.

[0018] The effect achieved by the above components is that the locking block can be moved by sliding the sliding rod.

[0019] Preferably, a third spring is sleeved on the sliding rod, one end of the third spring is fixedly connected to the locking block, and the other end of the third spring is fixedly connected to the inner wall of the sliding groove.

[0020] The effect achieved by the above components is as follows: when the mounting block is slidably inserted into the mounting slot, the two sides of the mounting block will press against the inclined surface of the locking block, causing the sliding rod to slide outward. At this time, the third spring will be compressed and contracted. Therefore, when the locking block comes into contact with the slot, the locking block will be locked into the slot under the action of the rebound force of the third spring, making the installation operation more convenient.

[0021] A distillation column for the pipeline interface support mechanism includes a distillation column body, a feed pipe fixedly connected to the distillation column body, and a base fixedly connected to the distillation column body.

[0022] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this utility model, by setting a support structure, the lower and upper sleeve clamps are respectively clamped at the upper and lower parts of the connection between the distillation column body and the feed pipe, and then fixed and clamped by bolts and connecting ears. The gasket is made of polytetrafluoroethylene, which can reduce damage to the anti-corrosion layer of the pipe during clamping. The base is welded to the reinforcing ring of the distillation column body, and the second bracket is installed on the base. The first and second brackets support the feed pipe. When it is necessary to disassemble and clean the feed pipe, the upper sleeve clamp is removed and the first bracket is rotated so that the first and second brackets are folded to prevent affecting the operation. After the operation is completed, the first bracket is rotated back to its original position, and then the sliding connecting block is slid into the connecting groove to limit the first bracket. This avoids the situation where the fixed structure of the bracket requires the complete removal of the bracket or difficult operation under the restriction of the bracket when disassembling the feed pipe, which greatly increases the difficulty and time cost of disassembling the feed pipe.

[0028] Example 1, such as Figure 1 As shown, a pipe interface support mechanism and a distillation column include a distillation column body 1, a feed pipe 2 fixedly connected to the distillation column body 1, and a base 3 fixedly connected to the distillation column body 1.

[0029] Reference Figure 2 and Figure 3A support structure 4 is provided on the feed pipe 2. The support structure 4 mainly consists of a lower sleeve clamp 41, on which an upper sleeve clamp 42 is provided. A first bracket 44 is fixedly connected to the lower sleeve clamp 41. The first bracket 44 is rotatably connected to a second bracket 45 via a hinge. Gaskets 43 are fixedly connected to both the lower sleeve clamp 41 and the upper sleeve clamp 42. A rectangular groove 49 is provided on the second bracket 45, and a connecting block 410 is slidably connected in the rectangular groove 49. A connecting groove 411 is provided on the first bracket 44. The lower sleeve clamp 41 and the upper sleeve clamp 42 are respectively clamped above the pipe connection between the distillation column body 1 and the feed pipe 2, and then... Bolts and connecting lugs secure it in place. Gasket 43 is made of polytetrafluoroethylene (PTFE) to reduce damage to the pipe's anti-corrosion layer during clamping. Base 3 is welded to the reinforcing ring of the distillation column body 1. The second bracket 45 is installed on base 3. The first bracket 44 and second bracket 45 support the feed pipe 2. When disassembly or cleaning of the feed pipe 2 is required, the upper clamp 42 is removed, and the first bracket 44 is rotated to fold it with the second bracket 45, preventing interference with operation. After operation, the first bracket 44 is rotated back to its original position, and then the connecting block 410 is slid into the connecting groove 411. The first support 44 provides a limiting mechanism, thus avoiding the situation where, due to the fixed structure of the support, disassembling the feed pipe 2 would require complete removal of the support or difficult operation under its constraint, significantly increasing the difficulty and time cost of disassembling the feed pipe 2. The first support 44 has a slot 46, in which a first spring 47 is fixedly connected. A damping rod 48 is also fixedly connected to the slot 46. The first spring 47 is sleeved on the damping rod 48. When the medium impacts the feed pipe 2, the impact force acts on the first spring 47, causing it to deform and absorb some energy. It then springs back to its original position, releasing the absorbed energy. Released, the damping rod 48 converts the damping energy into heat energy through friction on the inner wall, thereby reducing the impact and amplitude. A sliding rod 412 is slidably inserted on the second bracket 45. The sliding rod 412 is fixedly connected to the connecting block 410. The operator can move the connecting block 410 by sliding the sliding rod 412. A second spring 413 is fixedly connected to the connecting block 410. One end of the second spring 413 is fixedly connected to the inner wall of the rectangular groove 49. When the connecting block 410 is inserted into the connecting groove 411, the second spring 413 is in a contracted state. Therefore, the rebound force of the second spring 413 acts on the connecting block 410, making the limit more stable.

[0030] Reference Figure 2 and Figure 4The second bracket 45 is provided with an installation structure 5, which mainly consists of an installation block 51. The installation block 51 is fixedly connected to the second bracket 45. The base 3 has an installation groove 52. The installation block 51 can be quickly installed into the installation groove 52, and vice versa, it can be easily disassembled. The inner walls on both sides of the installation groove 52 are respectively provided with sliding grooves 53. The locking blocks 54 are slidably connected in the sliding grooves 53. The sides of the installation block 51 are respectively provided with locking slots 55. Sliding the locking blocks 54 so that they are locked into the corresponding locking slots 55 can limit the installation block 51. In the middle, the mounting block 51 can be limited, and the sliding block 54 can be moved by sliding the sliding rod 56. A third spring 57 is sleeved on the sliding rod 56. One end of the third spring 57 is fixedly connected to the locking block 54, and the other end of the third spring 57 is fixedly connected to the inner wall of the slide groove 53. When the mounting block 51 is slidably inserted into the mounting groove 52, the two sides of the mounting block 51 will press the inclined surface of the locking block 54, causing the sliding rod 56 to slide outward. At this time, the third spring 57 will be compressed and contracted. Therefore, when the locking block 54 comes into contact with the locking groove 55, the locking block 54 will be locked into the locking groove 55 under the action of the rebound force of the third spring 57, making the installation operation more convenient.

[0031] Working principle: The lower clamp 41 and upper clamp 42 are respectively clamped above and below the connection between the distillation column body 1 and the feed pipe 2, and then fixed and clamped with bolts and connecting lugs. The gasket 43 is made of polytetrafluoroethylene, which can reduce damage to the anti-corrosion layer of the pipe during clamping. The base 3 is welded to the reinforcing ring of the distillation column body 1. The second bracket 45 is installed on the base 3. The first bracket 44 and the second bracket 45 support the feed pipe 2. When it is necessary to disassemble and clean the feed pipe 2, the upper clamp 42 is removed and the first bracket 45 is rotated. The bracket 44 allows the first bracket 44 and the second bracket 45 to fold together, preventing interference with operation. After operation, the first bracket 44 is rotated to return to its original position, and then the sliding connecting block 410 is slid into the connecting groove 411 to limit the first bracket 44. This avoids the situation where, due to the fixed structure of the bracket, disassembling the feed pipe 2 requires complete removal of the bracket or difficult operation under the restriction of the bracket, which greatly increases the difficulty and time cost of disassembling the feed pipe 2. When the medium impacts the feed pipe 2, the impact force acts on the first spring. 47 causes the deformation to absorb some energy, then rebounds and releases the absorbed energy. At this time, the damping rod 48 converts the energy into heat energy through inner wall friction, thereby reducing the impact and amplitude. The operator can move the connecting block 410 by sliding the slide rod 412. When the connecting block 410 is inserted into the connecting groove 411, the second spring 413 is in a contracted state. Therefore, the rebound force of the second spring 413 acts on the connecting block 410, making the limit more stable. The mounting block 51 is inserted into the mounting groove 52, and the second bracket 45 can be quickly installed. Conversely, it can be easily disassembled. The sliding block 54 can be inserted into the corresponding slot 55 to limit the installation block 51. The sliding rod 56 can be used to move the block 54. When the installation block 51 is slidably inserted into the installation slot 52, the two sides of the installation block 51 will press the inclined surface of the block 54, causing the sliding rod 56 to slide outward. At this time, the third spring 57 will be compressed and contracted. Therefore, when the block 54 comes into contact with the slot 55, the block 54 will be inserted into the slot 55 under the action of the rebound force of the third spring 57, making the installation operation more convenient.
