Description

Technical Field

[0001] The utility model relates to the technical field of heat exchangers, and more specifically, to a shell and tube type high-efficiency heat exchanger. Background Art

[0002] Shell and tube heat exchanger, also known as shell and tube heat exchanger, is a wall heat exchanger that uses the wall of the tube bundle enclosed in the shell as the heat transfer surface. This type of heat exchanger has a simple structure, low cost, wide flow cross-section, and is easy to clean scale; but the heat transfer coefficient is low and the floor space is large. It can be made of various structural materials (mainly metal materials), can be used under high temperature and high pressure, and is the most widely used type.

[0003] However, since the heat exchange fluid usually contains a large amount of impurities, these impurities tend to settle under the influence of gravity after the fluid enters the heat exchanger. With long-term use, the inner and outer walls of the heat exchanger tube body will be covered with dirt, seriously affecting the heat exchange efficiency. To solve this problem, some shell and tube heat exchangers are equipped with filter plates inside when the fluid enters the pipeline to filter impurities. However, some fixed filter plates are difficult to remove, making it difficult to clean the filtered impurities. This causes the accumulation of impurities to clog the filter plate, thereby affecting the injection rate of the fluid. Utility Model Content

[0027] A liquid outlet pipe 7, the top of which is fixedly mounted to the bottom of the pipe box 2.

[0028] Among them, it also includes a baffle 5, a liquid inlet pipe 8, and a liquid outlet pipe 9. The baffle 5 is arranged inside the heat exchanger body 1, and the inner surface is fixedly installed with the heat exchange tube 4. The bottom of the liquid inlet pipe 8 is fixedly installed with the top of the heat exchanger body 1 and has the same structure as the liquid inlet pipe 6. The top of the liquid outlet pipe 9 is fixedly installed with the bottom of the heat exchanger body 1.

[0029] The clamping mechanism 65 includes a receiving block 650, a clamping column 651, a U-shaped rod 652, a pull rod 653, and a spring 654. The surface of the receiving block 650 is fixedly mounted on the outer surface of the connecting pipe 60, and the interior is slidably mounted on the bottom end of the connecting block 64. The clamping column 651 is arranged inside the receiving block 650 and is clamped and mounted inside the connecting block 64. The end of the U-shaped rod 652 is fixedly mounted on the side of the clamping column 651, and the outer surface is slidably mounted on the interior of the receiving block 650. The end of the pull rod 653 is fixedly mounted on the middle part of the U-shaped rod 652. One end of the spring 654 is fixedly connected to the side of the clamping column 651, and the other end is fixedly connected to the inner wall of the receiving block 650.

[0030] By setting the spring 654, after cleaning the impurities on the surface of the filter plate 63, the structure including the connecting pipe 61 is restored to its original state and installed on the top of the connecting pipe 60. At this time, the clamping column 651 needs to be moved again, and after the connecting block 64 is inserted into the interior of the receiving block 650, the pulling rod 653 is released. Under the restoring action of the squeezed spring 654, the clamping column 651 will move toward the interior of the connecting block 64 and be clamped and fixed thereto, thereby completing the fixation of the connecting pipe 61 and the connecting pipe 60.

[0031] Among them, the liquid inlet pipe 6 also includes an auxiliary liquid inlet mechanism 66, which is arranged inside the connecting pipe 60. The auxiliary liquid inlet mechanism 66 includes a motor 660, a worm 661, a turbine disc 662, and a worm wheel 663. The motor 660 is arranged on the outer surface of the connecting pipe 60, the end of the worm 661 is fixedly installed with the output end of the motor 660, the turbine disc 662 is arranged at the bottom of the filter plate 63, and the middle part of the worm wheel 663 is fixedly installed with the top of the turbine disc 662, and is meshed with the worm 661.

[0032] The auxiliary liquid inlet mechanism 66 further includes a connecting column 664 and a movable rod 665. The bottom of the connecting column 664 is fixedly mounted on the top of the worm gear 663, and the outer surface is rotatably mounted on the inner surface of the filter plate 63. The end of the movable rod 665 is fixedly mounted on the surface of the connecting column 664, and the bottom is rotatably mounted on the surface of the filter plate 63.

[0033] By setting up the movable rod 665, in the process of driving the worm gear 663 to rotate by the motor 660, the connecting column 664 connected to the top of the worm gear 663 rotates inside the filter plate 63, and drives the connecting column 664 to rotate along the top surface of the filter plate 63. On the one hand, the medium fluid flowing inside the connecting pipe 60 is "cut" by the rotation of the movable rod 665, and its liquid surface tension is destroyed, so that the medium fluid can more easily pass through the filter plate 63, thereby improving the circulation efficiency. On the other hand, the rotating movable rod 665 can stir the blocked impurities to avoid clogging of the mesh of the filter plate 63 where impurities are accumulated, thereby improving the practicality of the device.

[0034] The working process of the utility model is as follows:

[0035] When in use, the hot medium is added into the pipe box 2 through the liquid inlet pipe 1 6, enters the heat exchange tube 4 from the upper cavity of the pipe box 2, flows horizontally into the box tube on the right, enters the heat exchange tube 4 along 44, and flows horizontally into the lower cavity of the pipe box 2, and is discharged through the liquid outlet pipe 1 7. At the same time, the cold medium is added into the heat exchanger body 1 through the liquid inlet pipe 2 8, so that the cold medium flows inside the heat exchanger body 1 and the outer surface of the heat exchange tube 4, and exchanges heat with the heat of the circulating hot medium, and is then discharged through the liquid outlet pipe 2 9. In this process, the medium is filtered by the filter plate 63 installed inside the connecting pipe 60, so as to prevent the heat exchanger from being blocked.

[0036] After using for a period of time, when the filtered impurities need to be cleaned, the pull rod 653 can be pulled horizontally first to drive the connected U-shaped rod 652 to move sideways along the inside of the receiving block 650, and the clamping column 651 connected to the U-shaped rod 652 moves horizontally to separate from the inside of the connecting block 64, and squeezes the spring 654, so that the clamping mechanism 65 cancels the fixation of the connecting block 64, and then the connecting pipe 61 is moved upward to separate the connecting pipe 61 from the connecting pipe 60, and drive the connecting block 64 to separate from the inside of the receiving block 650, and at the same time, the pressing block 62 moves upward with the connecting pipe 61 to cancel the clamping of the filter plate 63. At this time, the impurities on the surface of the filter plate 63 can be cleaned to prevent the accumulation of impurities from clogging the filter plate, thereby affecting the injection rate of the fluid;

[0037] During the medium injection process, the motor 660 can be started, and the worm 661 connected to the output end of the motor 660 can rotate, driving the meshing worm wheel 663 to rotate, and the turbine disk 662 fixedly installed at the bottom of the worm wheel 663 rotates accordingly, so that the turbine disk 662 can convert the kinetic energy of the medium fluid inside the connecting pipe 60 into mechanical energy through rotation, thereby increasing the pressure or speed of the medium fluid, allowing the medium fluid to pass through the connecting pipe 60 more effectively, thereby improving the perfusion efficiency of the medium.
