Description

Technical Field

[0001] The utility model relates to the technical field of heat exchangers, and in particular to a shell and tube heat exchanger with an auxiliary supporting structure. Background Art

[0002] Shell and tube heat exchanger is a common heat exchange equipment, widely used in many industrial fields for heat exchange process. Shell and tube heat exchanger realizes heat transfer by introducing two fluids between the tube bundle and the shell. Usually, one fluid flows inside the tube, which is called the tube side fluid, and the other fluid flows outside the tube, which is called the shell side fluid. Heat is transferred through the tube wall, thus realizing heat exchange between the two fluids.

[0003] However, there are still some problems with the existing shell and tube heat exchangers during actual use. For example, the existing shell and tube heat exchangers are generally installed using rigid brackets. If the height of the installed shell and tube heat exchanger needs to be adjusted, the shell and tube heat exchanger needs to be removed and then replaced with a bracket of the corresponding height for reinstallation, which is a cumbersome process.

[0025] In order to make the purpose, technical solution and advantages of the implementation of the utility model clearer, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. Obviously, the described implementation is a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Reference Figure 1-Figure 4 The utility model provides a technical solution: a shell and tube heat exchanger with an auxiliary support structure, comprising a shell and tube heat exchanger 1, two fixing plates 2 are arranged on the bottom surface of the shell and tube heat exchanger 1, and a clamping plate 3 is movably clamped between the two fixing plates 2;

[0027] The adjusting component includes a bidirectional threaded rod 7, which is movably clamped on the inner walls of the two fixed plates 2. Two movable blocks 8 are arranged on the outer surface of the bidirectional threaded rod 7. The inside of the movable blocks 8 is provided with a threaded hole 1. The movable blocks 8 are threadedly sleeved on the outer surface of the bidirectional threaded rod 7 through the threaded hole 1. The two side surfaces of the movable blocks 8 are fixedly installed with plug-in shafts 9. A plurality of supports 10 are fixedly installed on the bottom surface of the clamping plate 3. A connecting rod 11 is arranged between the support 10 and the plug-in shaft 9. One end of the connecting rod 11 is movably connected to the outer surface of the plug-in shaft 9, and the other end of the connecting rod 11 is movably connected to the outer surface of the plug-in shaft 9. Inside the support 10, a motor 12 is provided on one side surface of the fixed plate 2, and the output end of the motor 12 is fixedly connected to one end of the plug-in shaft 9. When the motor 12 rotates clockwise, the two movable blocks 8 can be driven to move toward each other on the outer surface of the bidirectional threaded rod 7 under the action of the thread, thereby driving the angle of the connecting rod 11 to change. As the distance between the two movable blocks 8 gradually decreases, the clamping plate 3 can be driven to move upward inside the two shell and tube heat exchangers 1, so that the height of the shell and tube heat exchanger 1 becomes higher, thereby achieving the purpose of being able to flexibly adjust the height of the shell and tube heat exchanger 1;

[0028] A mounting ring 13 is fixedly installed on the outer surface of the motor 12, and a mounting plate 14 is fixedly installed on the outer surface of the mounting ring 13. One end of the mounting plate 14 is fixedly connected to a side surface of the fixing plate 2. The motor 12 can be stably installed by setting the mounting ring 13 and the mounting plate 14.

[0029] Two reinforcing plates 17 are disposed on one side surface of the fixing plate 2 , and both ends of the two reinforcing plates 17 are fixedly connected to the inner walls of the two fixing plates 2 , respectively. The reinforcing plates 17 can make the two fixing plates 2 more stable.

[0030] The installation component is used for the rapid installation of the shell and tube heat exchanger 1 and the clamping plate 3. The installation component includes a fixing sleeve 4, which is fixedly sleeved on the outer surface of the shell and tube heat exchanger 1. A bracket 5 is fixedly installed on the bottom surface of the fixing sleeve 4, and a bottom plate 6 is fixedly installed on the bottom surface of the bracket 5. Four threaded holes 2 are provided at the four corners of the bottom plate 6. A plurality of mounting holes 16 are correspondingly provided on the top surface of the clamping plate 3. Mounting bolts 15 are provided inside the threaded holes 2 and the mounting holes 16. The bottom plate 6 at the bottom of the shell and tube heat exchanger 1 is placed on the top surface of the clamping plate 3, and then the threaded holes provided inside the bottom plate 6 correspond to the mounting holes 16. Finally, the mounting bolts 15 are screwed into the threaded holes and the mounting holes 16 to fix the shell and tube heat exchanger 1 and the clamping plate 3, thereby achieving the purpose of rapid installation between the shell and tube heat exchanger 1 and the clamping plate 3.

[0031] Specifically, the working process or working principle of the shell and tube heat exchanger with an auxiliary support structure is as follows: when in use, the shell and tube heat exchanger 1 is first installed. When installing the shell and tube heat exchanger 1, it is only necessary to place the bottom plate 6 at the bottom of the shell and tube heat exchanger 1 on the top surface of the clamping plate 3, and then make the threaded holes opened inside the bottom plate 6 correspond to the mounting holes 16, and finally use the mounting bolts 15 to be screwed into the threaded holes and the mounting holes 16 to fix the shell and tube heat exchanger 1 and the clamping plate 3, thereby achieving the purpose of being able to quickly install the shell and tube heat exchanger 1 and the clamping plate 3;

[0032] After installation, it is only necessary to place the entire device at the required position for normal use. When it is necessary to adjust the height of the shell and tube heat exchanger 1, it is only necessary to start the motor 12. When the motor 12 is started, it drives the bidirectional threaded rod 7 to rotate inside the two shell and tube heat exchangers 1. When the motor 12 rotates clockwise, it can drive the two movable blocks 8 to move toward each other on the outer surface of the bidirectional threaded rod 7 under the action of the thread, thereby driving the angle of the connecting rod 11 to change. As the distance between the two movable blocks 8 gradually becomes smaller, the clamping plate 3 can be driven to move upward inside the two shell and tube heat exchangers 1, so that the height of the shell and tube heat exchanger 1 becomes higher. Conversely, when the motor 12 rotates counterclockwise, it can drive the clamping plate 3 to move downward inside the two shell and tube heat exchangers 1, so that the height of the shell and tube heat exchanger 1 becomes lower, thereby achieving the purpose of being able to flexibly adjust the height of the shell and tube heat exchanger 1.

[0033] It should be noted that the motor 12 is a device or equipment existing in the prior art, or a device or equipment that can be realized in the prior art. Its power supply, specific composition and principle are clear to those skilled in the art, so they are not described in detail.
