By arranging a motor, a screw and a scraper frame, when the motor rotates, the screw can be driven to rotate through the transmission of the worm and the worm gear. When the screw rotates, it can drive the cleaning plate to move to the right, thereby driving each group of scraper rings and the scraper frame to move to the right accordingly, so that each group of scraper rings can scrape off and remove the scale on the outer wall of each group of heat exchange tubes, and at the same time, the scraper frame can scrape off and remove the scale on the inner wall of the heat exchange tube, thereby improving the scale cleaning effect.

[0027] The filter unit includes a first threaded rod 501, a cylinder 502, a connecting plate 503 and a filter screen 504. The first threaded rod 501 is fixedly connected to the upper end of the cold fluid inlet and outlet pipe 2. The cylinder 502 is connected to the outer end of the first threaded rod 501. The connecting plate 503 is connected to the upper end of the cold fluid inlet and outlet pipe 2. A groove is provided at the inner upper end of the cold fluid inlet and outlet pipe 2. A limiting hole is provided at the middle position of the front and rear ends of the connecting plate 503. There are two first threaded rods 501, and the two first threaded rods 501 are respectively fixed to the front and rear ends of the bottom side of the groove. The outer side of the connecting plate 503 is slidably connected to the inner side of the groove, and the outer side of the first threaded rod 501 is slidably connected to the inner side of the limiting hole. Therefore, when the connecting plate 503 is slid to the inner side of the groove, the limiting hole will slide on the outer side of the first threaded rod 501, thereby limiting the movement of the connecting plate 503.
[0028] The inner side of the cylinder 502 is provided with an internal thread, and the lower end of the cylinder 502 abuts against the upper side of the connecting plate 503.
