[0018] The drain outlet 10 is connected to the heat exchange box 9 via a drain pipe. A water pump 11 is installed on the drain pipe. The top of the heat exchange box 9 is connected to a water inlet pipe 19, which is equipped with a water pump 2. A serpentine heat exchange pipe 20 is installed within the heat exchange box 9. The upper end of the serpentine heat exchange pipe 20 passes through the top of the heat exchange box 9 and is connected to a medium outlet pipe 22 via a rotary joint 1. The lower end of the serpentine heat exchange pipe 20 is fixedly connected to a vertical rotating pipe 16. The vertical rotating pipe 16 passes through the bottom of the heat exchange box 9 and is connected to a medium inlet pipe 23 via a rotary joint 2. A bevel gear 1 26 is fixed to the vertical rotating pipe 16 located outside the heat exchange box 9. The bevel gear 1 26 meshes with a bevel gear 28, which is connected to a stepper motor 27. The water in the cold water tank 1 is filtered and then enters the heat exchange box 9 for cooling. The cooled water is then passed back into the water distribution pipe 7, achieving water recycling within the cold water tank 1. The rotation of the serpentine heat exchange tube 20 can improve the fluidity of the water in the heat exchange box 9 and improve the heat exchange efficiency.

[0019] The heat exchange box 9 is connected to a refrigerator 21 , the medium outlet pipe 22 is connected to the inlet of the refrigerator 21 , the medium inlet pipe 23 is connected to the outlet of the refrigerator 21 , and a water pump 18 is provided on the medium inlet pipe 23 .

[0020] The heat exchange box 9 has a conical bottom, equipped with a slag discharge pipe. A vertical rotating pipe 16 extends from the slag discharge pipe. A slag discharge port 17 with an on / off valve is located on the sidewall of the slag discharge pipe. A second filter screen 12 is fixed to the top of the conical bottom. The filter screen 12 divides the heat exchange box 9 into a heat exchange chamber 13 and a filter chamber 14. The serpentine heat exchange tube 20 is located in the heat exchange chamber 13, and the vertical rotating pipe 16 is located in the filter chamber 14. A scraper 15 is provided in the filter chamber 14, contacting the inner wall of the conical bottom and fixedly connected to the vertical rotating pipe 16 via a connecting rod. This arrangement allows the water in the heat exchange box 9 to be filtered again to prevent impurities from contaminating the serpentine heat exchange tube 20 and affecting the heat exchange effect. The filtered impurities can be discharged through the slag discharge port 17.

[0021] A cleaning brush 24 is provided in the heat exchange chamber 13, the bristles of which are in contact with the serpentine heat exchange tubes 20, and the cleaning brush 24 is connected to the side wall of the heat exchange chamber 13 via a horizontal rod 25.

[0024] Working Principle: The rubber belt 5 to be cooled passes through the feed transition roller 3 and enters the cold water tank 1. The rubber belt 5 passes under each nip roller 6 and then passes through the discharge transition roller 4 at the discharge end of the cold water tank 1. Cold water from the water distribution pipe 7 is sprayed through the water nozzle 8 onto the rubber belt 5 lifted from the cold water tank 1, washing it and further cooling it. The cold water then falls into the cold water tank 1, and the cooled rubber belt 5 is transported away. The water in the cold water tank 1 is filtered by the filter 2 and then enters the heat exchange box 9 for cooling. The cooled water is then passed back into the water distribution pipe 7, realizing the recycling of the water in the cold water tank 1. During heat exchange within the heat exchanger, the rotation of the serpentine heat exchange tube 20 increases the fluidity of the water within the heat exchanger 9, improving heat exchange efficiency. The cooling medium within the serpentine heat exchange tube forms a circulation loop with the refrigerator via the medium inlet and outlet pipes. After cooling within the refrigerator, the cooling medium enters the serpentine heat exchange tube to exchange heat with the water within the heat exchanger, cooling the water within the heat exchanger. This prevents contamination of the cooling medium and has no adverse effects on the refrigerator. This ensures a long service life, excellent cooling performance, and high efficiency.
