Description

Technical Field

[0001] This utility model relates to the field of shell-and-tube condenser technology, specifically a shell-and-tube condenser for 3,5-dimethylbenzoic acid. Background Technology

[0002] 3,5-Dimethylbenzoic acid is an important organic chemical widely used in pharmaceuticals, cosmetics, and synthetic materials. Its production process often requires purification or solvent recovery through methods such as distillation and condensation. In this process, shell-and-tube condensers, as highly efficient heat exchangers, are typically used to cool and condense vapors, ensuring product purity and recovery efficiency. A shell-and-tube condenser consists of multiple tubes that condense vapors into liquids using cooling water or other cooling media, exhibiting high heat exchange efficiency and low energy consumption. Especially when processing high-boiling-point organic chemicals such as 3,5-dimethylbenzoic acid, shell-and-tube condensers can operate stably at high temperatures and effectively prevent cross-contamination between the condensed material and the cooling medium.

[0003] In the synthesis and purification of 3,5-dimethylbenzoic acid, tubular condensers are commonly used to cool the vapors generated during the reaction or distillation process, converting them into liquids for recovery. This process not only improves resource utilization efficiency but also reduces solvent waste and lowers production costs. Tubular condensers play a crucial role in the production of 3,5-dimethylbenzoic acid, ensuring smooth production through efficient heat exchange and condensation processes, and providing strong technical support for improving product purity and yield.

[0004] Traditional shell-and-tube condensers have a complex structure, typically requiring precise alignment and fixation during installation. Due to their fixed design and large size, installation and disassembly are cumbersome and require specialized tools and technicians. This inconvenience not only increases installation and maintenance time costs but also raises the workload of factory operators, impacting overall equipment efficiency. Secondly, existing shell-and-tube condensers are generally not height-adjustable in their design. Their fixed installation method limits their height flexibility. This limitation prevents adjustments to the condenser's position in certain production environments, hindering the optimization of the entire process flow. No solutions have yet been proposed to address these technical issues. Utility Model Content

[0005] To address the problems in related technologies, this utility model proposes a shell-and-tube condenser for 3,5-dimethylbenzoic acid, overcoming the aforementioned technical issues in existing technologies. The purpose of this utility model is to shorten maintenance and cleaning time through convenient installation and disassembly, reduce reliance on specialized tools and highly skilled operators, thereby lowering labor costs for maintenance and installation. Simultaneously, the adjustable height design allows the condenser to adapt to different process requirements and production environments, improving heat exchange efficiency and ensuring the equipment maintains good working condition under various operating conditions, thus enhancing equipment flexibility.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a shell-and-tube condenser for 3,5-dimethylbenzoic acid, comprising a shell-and-tube condenser body, a support plate provided at the bottom of the shell-and-tube condenser body, a clamping mechanism provided on the support plate, a base provided at the bottom of the support plate, and the base being connected to the support plate via a lifting mechanism;

[0007] The clamping mechanism includes a bidirectional screw, a slider, a locking block, a locking seat, and a movable plate. The support plate has an internal cavity with openings on both sides of its top. Two movable plates are symmetrically arranged on the top sides of the support plate, and a locking block is provided on each opposite side of the two movable plates. The bidirectional screw is located inside the cavity, with one end movably connected to the inner wall of the cavity and the other end penetrating the support plate and extending to the outside of the support plate, with a rotating handle fixedly connected to its end. Two sliders are provided, each sleeved on both ends of the bidirectional screw and threadedly connected to it. The top of each slider is fixedly connected to the movable plate, and the locking seat is fixedly installed at the top center of the support plate.

[0008] The lifting mechanism includes a cylinder, a support column, and a spring. The cylinder is fixedly mounted on the base, and the output end of the cylinder is connected to a support plate. The support column is fixedly mounted on the base, and the support plate is sleeved on the support column and movably connected to it. The spring is located below the support plate and is sleeved on the outer surface of the support column.

[0009] Preferably, a rubber pad is provided on each of the two card blocks on opposite sides, and a rubber pad is provided on the top of the card holder.

[0010] Preferably, the card block, rubber pad one, and rubber pad two are all arranged in an arc shape.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] (1) This utility model is a shell-and-tube condenser for 3,5-dimethylbenzoic acid. By setting a clamping mechanism, the rotating handle is rotated clockwise or counterclockwise to rotate the bidirectional screw fixedly connected to it. When the bidirectional screw rotates, it drives the two sliders threaded to it to move closer or further apart. When the sliders move, they drive the moving plate fixedly connected to them to move, thereby moving the locking block fixedly connected to the moving plate. This makes it convenient for the locking block to clamp or loosen the shell-and-tube condenser body of different sizes. The locking seat plays the role of supporting the shell-and-tube condenser body. Rubber pad one and rubber pad two can effectively increase the friction between the shell-and-tube condenser body and improve the firmness of the installation of the shell-and-tube condenser body. The convenient installation and disassembly method shortens the maintenance and cleaning time, reduces the dependence on professional tools and highly skilled operators, and thus reduces the labor cost of maintenance and installation.

[0013] (2) This utility model is a tubular condenser for 3,5-dimethylbenzoic acid. By setting up a lifting mechanism, the starting cylinder can drive the support plate connected to it to move on the support column, which effectively improves the stability of the support plate movement. The spring can play a buffering role and improve safety. The adjustable height design allows the condenser to adapt to different process requirements and production environment, improve heat exchange efficiency, ensure that the equipment can always maintain a good working state under different working conditions, and enhance the flexibility of the equipment.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] Example

[0020] Please see Figure 1-2This utility model proposes a technical solution for a shell-and-tube condenser for 3,5-dimethylbenzoic acid: A shell-and-tube condenser for 3,5-dimethylbenzoic acid includes a shell-and-tube condenser body 1, a support plate 2 at the bottom of the shell-and-tube condenser body 1, a clamping mechanism on the support plate 2, and a base 3 at the bottom of the support plate 2. The base 3 is connected to the support plate 2 through a lifting mechanism. Specifically, the shell-and-tube condenser body 1 adopts existing technology, the clamping mechanism can install shell-and-tube condenser bodies 1 of different sizes, and the height of the shell-and-tube condenser body 1 can be adjusted through the lifting mechanism to meet different usage requirements.

[0021] The clamping mechanism includes a bidirectional screw 4, a slider 5, a locking block 6, a locking seat 7, and a movable plate 8. The support plate 2 has an internal cavity with openings 9 on both sides of its top. Two movable plates 8 are symmetrically arranged on the top sides of the support plate 2, with a locking block 6 on each opposite side. The bidirectional screw 4 is located inside the cavity, with one end movably connected to the inner wall of the cavity and the other end penetrating the support plate 2 and extending to its exterior, with a rotating handle 10 fixedly connected to its end. Two sliders 5 are provided, each sleeved on both ends of the bidirectional screw 4 and connected to the screw. The screw 4 is threadedly connected to the top of the slider 5 and fixedly connected to the moving plate 8. The clamp 7 is fixedly installed at the top center of the support plate 2. Specifically, by rotating the handle 10 clockwise or counterclockwise, the bidirectional screw 4 fixedly connected to it is rotated. When the bidirectional screw 4 rotates, it drives the two sliders 5 threadedly connected to it to move closer or further apart. When the sliders 5 move, they drive the moving plate 8 fixedly connected to them to move, thereby moving the clamp 6 fixedly connected to the moving plate 8. This allows the clamp 6 to clamp or loosen the shell and tube condenser body 1 of different sizes. The clamp 7 serves to support the shell and tube condenser body 1.

[0022] The lifting mechanism includes a cylinder 11, a support column 12, and a spring 13. The cylinder 11 is fixedly mounted on the base 3, and the output end of the cylinder 11 is connected to the support plate 2. The support column 12 is fixedly mounted on the base 3, and the support plate 2 is sleeved on the support column 12 and movably connected to the support column 12. The spring 13 is located below the support plate 2 and is sleeved on the outer surface of the support column 12. Specifically, starting the cylinder 11 can drive the support plate 2 connected to it to move on the support column 12, effectively improving the stability of the movement of the support plate 2. The spring 13 can play a buffering role and improve safety.

[0023] Please see Figure 2 As shown, furthermore, rubber pad 14 is provided on the opposite side of each of the two card blocks 6, and rubber pad 25 is provided on the top of the card seat 7.

[0024] In this embodiment, rubber pad 14 and rubber pad 2 15 can effectively increase the friction between the rubber pad and the shell-and-tube condenser body 1, thereby improving the stability of the installation of the shell-and-tube condenser body 1.

[0025] Please see Figure 2 As shown, furthermore, the card block 6, rubber pad 14 and rubber pad 2 15 are all arranged in an arc shape.

[0026] In this embodiment, it can fit more closely to the shell-and-tube condenser body 1.

[0027] The working principle of this utility model:

[0028] The shell-and-tube condenser body 1 can be installed or removed via the clamping mechanism. By rotating the handle 10 clockwise or counterclockwise, the bidirectional screw 4 fixedly connected to it rotates. When the bidirectional screw 4 rotates, it drives the two sliders 5 threadedly connected to it to move closer or further apart. When the sliders 5 move, they drive the moving plate 8 fixedly connected to them to move, thereby moving the locking block 6 fixedly connected to the moving plate 8. This allows the locking block 6 to clamp or release shell-and-tube condenser bodies 1 of different sizes. The locking seat 7 supports the shell-and-tube condenser body 1. Rubber pad 14 and rubber pad 2 15 can effectively increase the friction between the shell-and-tube condenser body 1 and the shell-and-tube condenser body 1, improving the firmness of the installation of the shell-and-tube condenser body 1. The convenient installation and removal method shortens the maintenance and cleaning time, reduces the reliance on professional tools and highly skilled operators, and thus reduces the labor costs of maintenance and installation.

[0029] The height of the shell-and-tube condenser body 1 can be adjusted by the lifting mechanism. The starting cylinder 11 can drive the support plate 2 connected to it to move on the support column 12, which effectively improves the stability of the movement of the support plate 2. The spring 13 can play a buffering role to improve safety. The adjustable height design allows the condenser to adapt to different process requirements and production environments, improve heat exchange efficiency, ensure that the equipment can always maintain a good working condition under different working conditions, and enhance the flexibility of the equipment.
