Technical Field
[0001] The utility model belongs to the technical field of chemical equipment, and specifically relates to a heat exchanger for chemical equipment. Background Art
[0002] Chemical equipment is a general term for machines and equipment used in chemical industry production. In order to process raw materials into finished products of certain specifications in chemical production, it is often necessary to go through a series of chemical processes such as raw material pretreatment, chemical reaction, and separation and refining of reaction products. The machinery used to achieve these processes is often classified as chemical equipment. When chemical equipment is in use, many reactions are accompanied by high temperatures, such as distillation separators. The generated chemical materials need to be treated with heat exchangers before they can proceed to subsequent processes.
[0003] During the installation of existing heat exchangers, the connections with external devices are usually rigidly fixed by bolts with the cooperation of external tools. The bolts are very likely to loosen or strip during long-term use. Secondly, since multiple sets of bolts need to be used, the installation process is extremely time-consuming and labor-intensive. Secondly, water flow will cause a water hammer effect in the heat exchanger, causing the heat exchanger to vibrate. The vibration will cause the internal pipes of the heat exchanger to loosen or even leak. Therefore, we provide a heat exchanger for chemical equipment. Utility Model Content
[0004] The purpose of the utility model is to provide a heat exchanger for chemical equipment, which is used in conjunction with a protective plate, a damper and a shock absorber through the arrangement of a turntable, a rotating rod, a main gear, a sub-gear, a threaded rod, a threaded sleeve, a cross plate and a positioning rod to solve the problems raised in the above-mentioned background technology.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a heat exchanger for chemical equipment, comprising a base plate and a heat exchanger body, wherein shock absorbers are fixedly connected to the four sides of the top of the base plate, the top of the shock absorber is fixedly connected to a shell, a turntable is provided on the front surface of the shell, and a rotating rod is movably connected to the back of the turntable and located in the inner cavity of the shell, one end of the rotating rod is fixedly connected to a main gear, a sub-gear is meshed on the surface of the main gear, a threaded rod is fixedly connected to the inner wall of the sub-gear, a threaded sleeve is threadedly connected to the surface of the threaded rod, a cross plate is fixedly connected to the front and rear ends of one side of the cross plate, positioning rods are fixedly connected to the front and rear ends of one side of the cross plate, brackets are fixedly connected to the two sides of the bottom of the heat exchanger body, the bottom of the bracket is fixedly connected to the base, and the positioning rods pass through the limiting holes at the front and rear ends of the bottom of the base, dampers are fixedly connected to the two sides of the shell, and a protective plate is fixedly connected to one side of the damper.
[0006] By adopting the above scheme, the base is inserted into the inner cavity of the shell, and the base is initially limited by the limit blocks on both sides of the bottom of the shell. Then, the turntable is held and rotated, and the turntable drives the turn rod to rotate, and the turn rod drives the main gear to rotate, and the main gear drives the sub-gear to rotate, and the sub-gear drives the threaded rod to rotate. Because the threads on the two threaded rods are opposite, the threaded sleeve can be driven by the threaded rod to move toward or in the opposite direction, and the threaded sleeve can be driven to move outward by the threaded rod, and the cross plate can be driven to move outward by the threaded sleeve, and the positioning rod can be driven to move outward by the cross plate. Move until the positioning rod passes through the upper limit hole of the base to position the base to achieve the purpose of quick installation. Then, when the protective plate encounters a collision, the force generated by the impact is transmitted to the damper through the protective plate, and the impact force is offset by the damper to achieve the purpose of protection. When the heat exchanger body experiences a water hammer effect during operation, the vibration force is transmitted to the shell through the bracket and the base through the heat exchanger body, and the vibration force is transmitted to the shock absorber through the shell. The amplitude of the vibration is reduced through the shock absorber to prevent the pipes inside the heat exchanger body from loosening due to excessive vibration.
[0007] As a preferred embodiment of a heat exchanger for chemical equipment, slide grooves are provided on both sides of the top of the base plate, a slide rod is fixedly connected to the bottom of the inner side of the protective plate, and the surface of one end of the slide rod is slidably connected to the inner wall of the slide groove.
[0008] By adopting the above solution, the slide bar is limited by setting the slide groove, which reduces the shaking of the slide bar during operation and greatly improves the stability of the slide bar.
[0009] As a preferred embodiment of a heat exchanger for chemical equipment, one end of the threaded rod is movably connected to a bearing, and one side of the bearing is fixedly connected to one side of the inner cavity of the shell.
[0010] By adopting the above solution and setting the bearing, the wear of the threaded rod during operation is reduced, thereby greatly improving the service life of the threaded rod.
[0011] As a preferred embodiment of a heat exchanger for chemical equipment, one side of the protective plate is arc-shaped, and the protective plate is a hard rubber plate.
[0012] By adopting the above scheme, since the protective plate is in an arc shape, the impact force can be dispersed to prevent the impact force from being too concentrated and causing damage to the protective plate.
[0013] As a preferred embodiment of the heat exchanger for chemical equipment, anti-skid pads are bonded to four sides of the bottom of the base plate.
[0014] By adopting the above solution and providing the anti-skid pad, the device has an anti-skid function, thereby improving the stability of the base plate.
[0015] As a preferred embodiment of the heat exchanger for chemical equipment, a guide groove is provided on the inner wall of the shell, a guide block is fixedly connected to the back of the threaded sleeve, and one end of the guide block is slidably connected to the inner cavity of the guide groove.
[0016] By adopting the above scheme, the guide groove is set to limit the guide block and assist the threaded sleeve to move, thereby improving the smoothness of the device during operation.
[0017] Compared with the prior art, the beneficial effects of the utility model are:
[0018] 1. The utility model drives the rotating rod to rotate through the rotating disk, drives the main gear to rotate through the rotating rod, drives the sub-gear to rotate through the main gear, and drives the threaded rod to rotate through the sub-gear. Because the threads on the two threaded rods are opposite, the threaded sleeves can be driven by the threaded rods to move toward or oppositely, the threaded sleeves can be driven to move outward through the threaded rods, the cross plate can be driven to move outward through the threaded sleeves, and the positioning rods can be driven to move outward through the cross plate until the positioning rods pass through the upper limit hole of the base, so as to position the base and achieve the purpose of rapid installation.
[0019] 2. The utility model transmits the force generated by the impact to the damper through the protective plate, and the impact force is offset by the damper to achieve the purpose of protection. When the water hammer effect occurs in the heat exchanger body during operation, the vibration force is transmitted to the shell through the bracket and the base through the heat exchanger body, and the vibration force is transmitted to the shock absorber through the shell. The amplitude of the vibration is reduced by the shock absorber to prevent the pipe inside the heat exchanger body from loosening due to excessive vibration. BRIEF DESCRIPTION OF THE DRAWINGS

A shell 3 is fixedly connected to the top of the shock absorber 2. Figure 3 As shown, a guide groove is provided on the inner wall of the shell 3, a guide block is fixedly connected to the back of the threaded sleeve 9, and one end of the guide block is slidably connected to the inner cavity of the guide groove. By setting the guide groove, the guide block is limited, and the auxiliary threaded sleeve 9 is moved, which improves the smoothness of the device during operation. A turntable 4 is provided on the front surface of the shell 3, and a rotating rod 5 is movably connected to the back of the turntable 4 and located in the inner cavity of the shell 3. One end of the rotating rod 5 is fixedly connected to a main gear 6, and a sub-gear 7 is meshed on the surface of the main gear 6. A threaded rod 8 is fixedly connected to the inner wall of the sub-gear 7. Figure 3 As shown, one end of the threaded rod 8 is movably connected with a bearing, and one side of the bearing is fixedly connected to one side of the inner cavity of the shell 3. By setting the bearing, the wear of the threaded rod 8 during operation is reduced, and the service life of the threaded rod 8 is greatly improved. The surface of the threaded rod 8 is threadedly connected with a threaded sleeve 9, and the front surface of the threaded sleeve 9 is fixedly connected with a cross plate 10. The front and rear ends of one side of the cross plate 10 are fixedly connected with positioning rods 11. Both sides of the bottom of the heat exchanger body 12 are fixedly connected with brackets 13, and the bottom of the bracket 13 is fixedly connected with a base 14, and the positioning rod 11 passes through the limiting holes at the front and rear ends of the bottom of the base 14. Both sides of the shell 3 are fixedly connected with dampers 16, and one side of the damper 16 is fixedly connected with a protective plate 15. The base 14 is inserted into the inner cavity of the shell 3, and the base 14 is initially limited by the limiting blocks on both sides of the bottom of the shell 3. Next, hold the turntable 4 to rotate, and the turntable 4 drives the turntable 5 to rotate, and the turntable 4 drives the main gear 6 to rotate, and the main gear 6 drives the sub-gear 7 is rotated, and the threaded rod 8 is driven to rotate through the secondary gear 7. Because the threads on the two threaded rods 8 are opposite, the threaded sleeve 9 can be driven to move in the opposite or opposite directions through the threaded rod 8, and the threaded sleeve 9 is driven to move outward through the threaded rod 8, and the cross plate 10 is driven to move outward through the threaded sleeve 9, and the positioning rod 11 is driven to move outward through the cross plate 10 until the positioning rod 11 passes through the upper limit hole of the base 14, and the base 14 is positioned to achieve the purpose of rapid installation. Then, when the protective plate 15 encounters a collision, the force generated by the impact is transmitted to the damper 16 through the protective plate 15, and the impact force is offset by the damper 16 to achieve the purpose of protection. When the heat exchanger body 12 has a water hammer effect during operation, the vibration force is transmitted to the shell 3 through the bracket 13 and the base 14 through the heat exchanger body 12, and the vibration force is transmitted to the shock absorber 2 through the shell 3. The amplitude of the vibration is reduced by the shock absorber 2 to prevent the pipeline inside the heat exchanger body 12 from loosening due to excessive vibration.

Anti-skid pads are bonded around the bottom of the substrate 1, and the number of anti-skid pads is four. Through the provision of the anti-skid pads, the device has an anti-skid function, which improves the stability of the substrate 1.
