Description

Technical Field

[0001] The utility model relates to the technical field of heat exchangers, in particular to a heat exchanger. Background Technique

[0002] A heat exchanger is a device that transfers part of the heat of a hot fluid to a cold fluid, also known as a heat exchanger. Heat exchangers play an important role in many industrial productions such as chemical engineering, petroleum, power, food, etc. In chemical production, heat exchangers can be used as heaters, coolers, condensers, evaporators, reboilers, etc., and are widely used. However, the vibration generated by the internal fluid flow velocity of the heat exchanger will cause the tube body to vibrate. When the vibration amplitude of the tube body is large for a long time, it will cause damage to the tube body. Therefore, there is a particular need for a heat exchanger.

[0003] However, the existing heat exchangers will have hot and cold changes during operation, which will cause the heat exchangers to vibrate. And currently, the bases of heat exchangers on the market lack shock absorption and buffering effects. After long-term use, the vibration generated by the internal fluid flow velocity will cause the tube body to vibrate. When the tube body is in a large vibration amplitude for a long time, it will cause damage to the tube body. At the same time, the hot medium and the cold medium are in contact with the pipeline at the same time, and finally it will cause the aging of the heat exchanger pipeline to accelerate. Content of the Utility Model

[0004] The purpose of the utility model is to provide a heat exchanger, specifically related to the technical field of heat exchangers, to solve the problem that the existing heat exchanger base lacks shock absorption and buffering effects mentioned in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A heat exchanger includes a heat exchanger housing and a buffer mechanism. A support mechanism is installed on one side of the surface of the heat exchanger housing, and a buffer mechanism is arranged inside the support mechanism;

[0006] The buffer mechanism includes a second screw, a sound insulation friction pad, a first gasket, a second nut, a rubber pad, an upper mounting plate, a second gasket, an upper gasket, a third nut, a spring, a lower gasket and a lower mounting plate.

Specific implementation manners

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1-4 , the present utility model provides a technical solution: a heat exchanger, including a heat exchanger housing 1 and a buffer mechanism 3. On one side of the surface of the heat exchanger housing 1, a support mechanism 2 is installed, and a buffer mechanism 3 is arranged inside the support mechanism 2;

[0021] The buffer mechanism 3 includes a second screw 301, a sound insulation friction pad 302, a first gasket 303, a second nut 304, a rubber pad 305, an upper mounting plate 306, a second gasket 307, an upper gasket 308, a third nut 309, a spring 310, a lower gasket 311 and a lower mounting plate 312. The second screw 301 is connected inside the support mechanism 2. One end of the second screw 301 is sleeved with the sound insulation friction pad 302. One end of the second screw 301 is sleeved with the first gasket 303. One end of the second screw 301 is connected with the second nut 304. One side of the sound insulation friction pad 302 is connected with the rubber pad 305. One side of the rubber pad 305 is connected with the upper mounting plate 306. One side of the upper mounting plate 306 is connected with the second gasket 307. One side of the upper mounting plate 306 is connected with the upper gasket 308. One side of the second gasket 307 is connected with the third nut 309. One side of the upper gasket 308 is fixedly connected with the spring 310. One end of the spring 310 is fixedly connected with the lower gasket 311. One side of the lower gasket 311 is fixedly connected with the lower mounting plate 312. Through the arrangement of the second screw 301, the sound insulation friction pad 302, the first gasket 303, the second nut 304, the rubber pad 305, the upper mounting plate 306, the second gasket 307, the upper gasket 308, the third nut 309, the spring 310, the lower gasket 311 and the lower mounting plate 312, when shock absorption is required during the operation of the heat exchanger housing 1, the vibration is first transmitted to the upper mounting plate 306. The rubber pad 305 on one side of the upper mounting plate 306 has a certain elasticity and can initially absorb and buffer part of the impact force. The sound insulation friction pad 302 behind the rubber pad 305 can further reduce vibration and noise. Then, through the connection and support of each component by the second screw 301, the first gasket 303 and the second nut 304 are used to fix and adjust the position of the components on the second screw 301. Subsequently, the vibration is transmitted from the upper mounting plate 306 to the upper gasket 308, and then compresses the spring 310 connected thereto. Then, the spring 310 stores energy during the compression process and slows down the transmission of the impact force through its own telescopic movement, thereby achieving the buffer effect. The lower gasket 311 and the lower mounting plate 312 provide support and fixation for the other end of the spring 310. Finally, the second gasket 307 and the third nut 309 further play an auxiliary role in fixing and adjusting.

[0022] Furthermore, two groups of springs 310 are provided. The upper gasket 308 and the lower gasket 311 have the same size and are correspondingly distributed. Through the arrangement of the springs 310, the two groups of springs 310 can share and absorb more impact forces. Compared with a single spring 310, the buffer effect is more significant, and it can more effectively reduce the strong impact and vibration received by the heat exchanger housing 1.

[0023] Furthermore, two groups of lower gaskets 311 are provided and two groups of upper gaskets 308 are provided. Through the provision of the upper gaskets 308 and the lower gaskets 311, the upper gaskets 308 and the lower gaskets 311 are of the same size and correspondingly distributed, so that the impact force can be transmitted to the spring 310 more evenly, avoiding the concentration of force in a certain place, thereby ensuring the balance and stability of the force.

[0024] Furthermore, the second screw 301 passes through the upper mounting plate 306 and is connected to the lower mounting plate 312. The second screw 301 passes through the interior of the sound insulation friction pad 302. The provision of the second screw 301 helps to fix the position of the sound insulation friction pad 302 so that it can stably perform the functions of sound insulation and friction reduction; at the same time, it also provides a coherent support and connection structure for the assembly of the entire mechanism, which helps to improve the integrity and stability of the entire buffer system.

[0025] Furthermore, the support mechanism 2 includes a pad 201, a wear-resistant pad 202, a seat plate 203, a bottom plate 204, a reinforcing plate 205, a mounting hole 206, a rib plate 207, a first screw 208, a connecting plate 209 and a first nut 210. The pad 201 is welded to one side of the heat exchanger housing 1, the wear-resistant pad 202 is bonded to one side of the pad 201 surface, the seat plate 203 is welded to one side of the pad 201, the bottom plate 204 is welded to one side of the seat plate 203, and one side of the seat plate 203 is fixedly connected to the bottom plate 204. The bottom plate 204 has a reinforcing plate 205, a mounting hole 206 is opened on one side of the bottom plate 204, a rib plate 207 is connected to one side of the bottom plate 204, a first screw 208 is connected to one side of the mounting hole 206, a connecting plate 209 is welded to one side of the rib plate 207, and one end of the first screw 208 is connected to a first nut 210, through the pad 201, the wear pad 202, the seat plate 203, the bottom plate 204, the reinforcing plate 205, the mounting hole 206, the rib plate 207, the first screw 208, the connecting plate 209 and The first nut 210 is set. When the heat exchanger shell 1 is working, the force and vibration generated by the heat exchanger shell 1 are transmitted to the pad 201 welded thereto. The pad 201 disperses part of the force and transmits the force to the seat plate 203 through welding connection. The seat plate 203 bears the main supporting force and transmits it to the bottom plate 204 welded thereto. The bottom plate 204 further stabilizes the support by expanding the contact area. The rib plate 207 on one side of the bottom plate 204 strengthens the structure of the bottom plate 204. The connecting plate 209 welded on one side of the rib plate 207 helps to disperse and transmit the force, making it more stable. Secondly, the wear-resistant pad 202 bonded to the surface of the pad 201 reduces the friction and wear between the heat exchanger shell 1 and the pad 201, protects the components and prolongs the service life. The reinforcing plate 205 on one side of the seat plate 203 enhances the strength of the seat plate 203 to prevent it from deforming when subjected to force. Finally, through the mounting hole 206, the heat exchanger shell 1 is fixed to the mounting position using a combination of the first screw 208 and the first nut 210.

[0026] Furthermore, one side of the rib plate 207 is connected to the connecting plate 209, and the pad 201 is a semi-arc structure. Through the setting of the pad 201, the pad 201 with a semi-arc structure can better fit the shape of the heat exchanger shell 1 and increase the contact area, thereby more effectively dispersing and bearing the force from the heat exchanger shell 1.

[0027] Furthermore, two groups of reinforcing plates 205 are provided, and the reinforcing plates 205 are of a triangular structure. The first screw 208 and the first nut 210 are threadedly connected. Through the arrangement of the reinforcing plates 205, the reinforcing plates 205 of the triangular structure have the characteristics of good stability, and can significantly enhance the structural strength of the seat plate 203, so that it is not easy to be deformed or damaged when it is subjected to a large load.

[0028] Working principle: First, the heat exchanger shell 1 is fixed at the installation position through the installation hole 206 using the combination of the first screw 208 and the first nut 210. Then, when the heat exchanger shell 1 is working, the force and vibration generated by it will be transmitted to the pad 201 welded thereto. After the pad 201 disperses part of the force, the force is transmitted to the seat plate 203 through the welding connection. The seat plate 203 bears the main supporting force and transmits it to the bottom plate 204 welded thereto. The bottom plate 204 further stabilizes the support by virtue of the enlarged contact area. The rib plate 207 on one side of the bottom plate 204 strengthens the structure of the bottom plate 204. The connecting plate 209 welded on one side of the rib plate 207 helps to disperse and transmit the force, making the whole more stable. Then, the wear-resistant pad 202 bonded to the surface of the pad 201 can reduce the friction and wear between the heat exchanger shell 1 and the pad 201, thereby protecting the components and extending their service life. The reinforcing plate 205 on one side of the seat plate 203 enhances the strength of the seat plate 203. , to prevent it from deforming when subjected to force. Secondly, when the heat exchanger housing 1 needs to be damped during operation, the vibration is first transmitted to the upper mounting plate 306. The rubber pad 305 on one side of the upper mounting plate 306 has a certain elasticity and can initially absorb and buffer part of the impact force. The sound insulation friction pad 302 behind the rubber pad 305 can further reduce vibration and noise. Then the second screw 301 is used to connect and support the various components. The first gasket 303 and the second nut 304 are used to fix and adjust the position of the component on the second screw 301. Then the vibration is transmitted to the upper gasket 308 through the upper mounting plate 306, thereby compressing the spring 310 connected thereto. The spring 310 stores energy during the compression process and slows down the transmission of the impact force through its own telescopic movement, thereby achieving a buffering effect. The lower gasket 311 and the lower mounting plate 312 provide support and fixation for the other end of the spring 310. Finally, the second gasket 307 and the third nut 309 further play a role in auxiliary fixation and adjustment.

[0029] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
