[0022] Reference Figure 1-Figure 3 A suction filter capable of cold and heat exchange comprises an upper shell 1 and a lower shell 2. A servo motor 11 providing power is fixed to an outer wall of one side of the upper shell 1 by bolts. A driving shaft of the servo motor 11 passes through the upper shell 1 and is keyed to a transmission shaft. A helical gear 13 is keyed to one side of the transmission shaft. A support frame is provided on an inner wall of one side of the upper shell 1. A helical gear 13 is also rotatably connected to one side of the support frame. The helical gears 13 are meshed with each other. An output shaft of the helical gear 13 is rotatably connected to a rotating connecting rod 12. A brush 20 is slidably connected to one side of the rotating connecting rod 12. A slide groove is provided on the upper surface of the brush 20. The output shaft of the rotating connecting rod 12 is rotated along the slide groove. The groove moves, a second heat exchanger 19 is provided on the inner wall of one side of the upper shell 1, and a coarse filter 14 is provided on the upper surface of the second heat exchanger 19 to intercept larger particles. The servo motor 11 drives the bevel gear 13 to rotate, and the bevel gear 13 then drives the rotating connecting rod 12 to rotate. Slide grooves are provided on the inner walls of both sides of the upper shell 1, so that the brush 20 reciprocates along the slide groove on the coarse filter 14 to scrape off the residue on the coarse filter 14. A microporous filter membrane 18 is provided on the inner wall of one side of the lower shell 2 to further filter the residue that the coarse filter 14 cannot filter. A guide port 17 is provided on the lower surface of the lower shell 2 to guide the filtered liquid out of the suction filter.

[0023] Among them, a heat exchanger 8 is provided on the inner wall of one side of the lower shell 2, and the heat exchanger 8 is provided with a plurality of straight holes connecting the upper and lower ends of the heat exchanger 8, and the outer walls on both sides of the heat exchanger 8 are provided with a cold medium inlet 4, a hot medium inlet 5 and a cold medium outlet 6, a hot medium outlet 7 for controlling the internal temperature of the filter.

[0024] Among them, the outer walls on both sides of the upper shell 1 and the lower shell 2 are provided with positioning holes 9 and mounting plates 10. The mounting plates 10 are fixed to the positioning holes 9 by bolts, so that the upper shell 1 and the lower shell 2 are fixed to each other. When the microporous filter membrane 18 needs to be replaced, the fixing screws can be unscrewed and the fixing plate 10 can be taken out. At this time, the upper shell 1 and the lower shell 2 are separated, and the microporous filter membrane 18 can be replaced.

[0027] Working principle: When the suction filter is working, the exchange of hot and cold media in the heat exchanger 8 is controlled to control the temperature of the solution in the suction filter, and then the temperature detector 15 is used to make the solution reach the temperature of minimum solubility. At this time, the servo motor 11 is started, and the servo motor 11 drives the bevel gear 13 to rotate.
