[0025] In this embodiment: after the liquid enters the auxiliary pipe 51 from the connecting pipe 52, the liquid will pass through the filter element 58, which can absorb and intercept impurities in the liquid in the auxiliary pipe 51. The filtered liquid enters the feed port 3 through the auxiliary pipe 51, and the sealing end cover 54 and the filter element 58 can be removed from the auxiliary pipe 51 through the connecting mechanism 59 for cleaning, thereby reducing the problem of a large amount of impurities in the liquid entering the equipment, causing inconvenience in cleaning.

[0026] Specifically, the filter element 58 includes a shaft 581 , which is fixedly connected to the surface of the sealing end cover 54 , a plurality of adsorption elements 582 are fixedly connected to the surface of the shaft 581 , and a scraper 583 is fixedly connected to one end of the shaft 581 away from the sealing end cover 54 .

[0027] In this embodiment: the multiple adsorption elements 582 in the filter element 58 can filter and adsorb impurities in the liquid. At the same time, after the filter element 58 is removed with the sealing end cover 54, the scraper 583 in the filter element 58 can scrape off the impurities in the auxiliary tube 51, and the cleaning operation can be carried out.

[0028] Specifically, one end of the sealing end cover 54 is fixedly connected to a handle 55 , and the handle 55 facilitates the movement of the sealing end cover 54 and the hollow block 56 in the slide rod 57 , thereby taking out the filter element 58 for cleaning.

[0029] Specifically, the connecting mechanism 59 includes two threaded caps 591 , and the two threaded caps 591 are arranged at one end of the slide rod 57 . A threaded groove 592 is provided at one end of the slide rod 57 , and the threaded caps 591 are threadedly connected to the threaded groove 592 .

[0030] In this embodiment: after the sealing end cover 54 drives the filter element 58 to be inserted into the auxiliary tube 51, the threaded cap 591 is rotated, and the threaded cap 591 is threadedly connected to the threaded groove 592 at one end of the slide rod 57, so that the sealing end cover 54 can be connected.

[0036] In this embodiment, the movable base 533 cooperates with the roller 534 to move on the bottom plate 531, thereby improving the usability.

[0037] Working principle: By setting up the filtering device 5, when the liquid enters the heat exchanger body 1, the liquid first enters the auxiliary pipe 51 through the connecting pipe 52. The multiple adsorption elements 582 in the filter element 58 can adsorb and filter the impurities in the liquid in the auxiliary pipe 51. The filtered liquid enters the feed port 3 from the auxiliary pipe 51 and enters the heat exchanger body 1. When cleaning later, open the connecting mechanism 59, rotate the threaded cap 591, and remove the threaded cap 591 from the threaded groove 592 at one end of the slide rod 57, thereby untying the restraint on the sealing end cover 54, and then use the handle 55 to pull out the sealing end cover 54 and the filter element 58, and then empty it. The core block 56 can slide on the slide rod 57. When the sealing end cover 54 moves, the support rod 532, the movable seat 533 and the roller 534 in the support assembly 53 slide on the bottom plate 531 to support the sealing end cover 54. After the filter element 58 is pulled out, the scraper 583 in the filter element 58 can scrape out the impurities in the auxiliary tube 51, and the adsorption element 582 can be cleaned. By setting the filtering device 5, it is convenient to filter the liquid entering the graphite heat exchanger and absorb and filter out the impurities in advance. There is no need to disassemble the heat exchanger as a whole for cleaning, thereby improving the overall practicality of the equipment.
