[0044] Working principle: When deoxygenating the feed water, the feed water enters the filter frame 502 through the water inlet pipe 506. At this time, the U-shaped partition 509 blocks the feed water. At this time, the feed water is initially filtered through the filter cartridge 534. At the same time, the drive motor 508 is started, and the drive motor 508 drives the rotating push rod 517 to make the roller 518 drive the tooth block end of the T-shaped tooth plate 516 to move back and forth in an arc shape, thereby making the linkage gear 514 rotate in both directions, and then the adjusting gear 512 drives the rotating circular tube 511 to drive the filter cartridge 534 to rotate in both directions, on the one hand, to prevent the filter end of the filter cartridge 534 from always facing the feed water. At the water inlet end, the cleaning brush plate 520 on the multiple extrusion springs 519 on the U-shaped partition 509 cleans the outside of the filter cartridge 534 to prevent the filter cartridge 534 from being blocked, and then the water enters the filter frame 2 504 through the connecting pipe 510, and the water is filtered twice by the filter plate 523 to improve the filtering effect of the security filter 5. While the filter plate 523 is filtering, the universal motor 522 is started, and the notched gear 526 on the rotating round rod 525 is driven to rotate by the universal motor 522. When the tooth block end of the notched gear 526 is meshed with the linkage gear rod 531, the linkage gear rod 531 drives the sealing slide plate 530 to rotate. The movement simultaneously drives the lifting slider 527 to move. At this time, the return springs 529 on the upper and lower sides of the lifting slider 527 are squeezed and stretched respectively. When the notched gear 526 is separated from the linkage gear rod 531, the return spring 529 rebounds quickly, so that the filter plate 523 is in a vibrating state to prevent the accumulation of impurities above the filter plate 523. The filtered water enters the downstream equipment. When the cold water inlet end of the heat exchanger 10 is inlet, the water flows into the heat exchanger 10 through the cold water inlet pipe 1103. The cold water inlet pipe 1103 is located in the cooling frame 1101 in a snake shape, thereby increasing the flow of water and the cooling frame 110 1, start the blower body 1112, and blow the cold air to the outer wall of the cold water inlet pipe 1103 through the blower body 1112. At the same time, start the servo motor 1107, and drive the limiting rotating block 1114 through the servo motor 1107 to make the rotating cylinder 1115 rotate in a circle, so that the slide seat 1111 slides back and forth on the guide track 1110, and the slide frame 1109 slides back and forth outside the limiting cylinder 1108, so that the blower body 1112 moves in a square shape, thereby evenly blowing the cold air to the outer wall of the cold water inlet pipe 1103, thereby improving the cooling effect on the water flow and ensuring the normal use of the heat exchanger 10.
