When completed, the operator can pour the liquid into the filter chamber 15 from the liquid inlet 25. At this time, the liquid can be filtered through the filter screen 14, and the installation bar 13 can be limited by setting the spring 18, the telescopic rod 17 and the limiting plate 19. At the same time, when the liquid flow rate slows down, the spring 18 can rebound, so that the filter screen 14 can be shaken to prevent excessive impurities on the filter screen 14 from clogging it, and then when the shell and tube heat exchanger body 11 is in operation, the impurities can be filtered.

[0028] Reference Figure 1-Figure 4In a preferred embodiment, the telescopic rod 17 is provided in two groups, and the two groups of telescopic rods 17 are both arranged inside the shell and tube heat exchanger body 11. A spring 18 is sleeved on the surface of the telescopic rod 17, and a limiting plate 19 is provided at one end of the spring 18. The other end of the spring 18 is fixed to one end of the telescopic rod 17. The limiting plate 19 is arranged on one side of the mounting bar 13. A filter chamber 15 is provided inside the shell and tube heat exchanger body 11, and the mounting bar 13 is arranged inside the filter chamber 15. A limiting groove 16 is provided inside the filter chamber 15, and the telescopic rod 17 is arranged inside the limiting groove 16. A mounting plate 2 is provided on the top of the shell and tube heat exchanger body 11. By providing the mounting plate 2, the mounting bar 13 can be limited. A threaded rod 21 is provided inside the mounting plate 2. Through the mutual cooperation of the mounting bar 13, the filter screen 14, the threaded rod 21 and the shell and tube heat exchanger body 11, when the operator needs to clean the impurities on the filter screen 14 on the mounting bar 13 inside the shell and tube heat exchanger body 11, the operator can take out the threaded rod 21 from the inside of the shell and tube heat exchanger body 11, and then open the mounting plate 2.

[0029] Reference Figure 1-Figure 4 In a preferred embodiment, the size of the mounting bar 13 is adapted to the size of the filter chamber 15.

[0030] Specifically, the working process or working principle of the shell and tube heat exchanger with filtering effect is as follows: in the specific filtering of the shell and tube heat exchanger, when the shell and tube heat exchanger is working, when heat exchange is carried out between fluids, there will be some impurities in the internal liquid, and these impurities are easy to stick to one end of the heat exchanger, and the shell and tube heat exchanger usually does not have a filtering function, and cannot filter out these impurities, and it is not convenient to clean the impurities after filtering, and it is not convenient for the operator to use. Therefore, the technical solution can solve the above problems. When the operator needs to filter the impurities inside the shell and tube heat exchanger body 11, the operator can first fix the two sets of fixing plates 12 on the top of both sides of the shell and tube heat exchanger body 11 respectively, and then the operator can rotate the installation bar 13 to set the filter screen 14 inside the filter chamber 15, and then fix the installation plate 2 on the top of the shell and tube heat exchanger body 11. When completed, the operator can pour the liquid into the filter chamber 15 from the liquid inlet 25. At this time, the filter screen passes through the filter chamber 15. 14, so that the liquid can be filtered, and by setting the spring 18, the telescopic rod 17 and the limiting plate 19, the installation bar 13 can be limited, and at the same time, when the liquid flow rate slows down, the spring 18 can rebound, so that the filter screen 14 can be shaken to prevent the filter screen 14 from being blocked by too many impurities, and then when the shell and tube heat exchanger body 11 is in operation, the impurities can be filtered. When the operator needs to clean the impurities on the filter screen 14 on the installation bar 13 inside the shell and tube heat exchanger body 11, the operator can take out the threaded rod 21 from the inside of the shell and tube heat exchanger body 11, and then open the installation plate 2. After the opening is completed, the operator can rotate the installation bar 13, and the installation bar 13 drives the filter screen 14 and the impurities to rotate out of the filter cavity 15 of the shell and tube heat exchanger body 11 at the same time, so that the impurities on the filter screen 14 can be cleaned or the filter screen 14 can be replaced, which is convenient for the operator to use, and all processes are completed.
