A drain pipe 65 communicating with the interior of the volute 64 is fixedly arranged at the top of the volute 64. A first impeller 66 is rotatably arranged inside the volute 64 via a rotating shaft. Both ends of the rotating shaft rotatably pass through the volute 64 and extend to the outside. Hot air delivery assemblies 67 are provided on both sides of the outer wall of the volute 64. Each hot air delivery assembly 67 includes a bellows 671 fixedly mounted on the outer wall of the volute 64. A second impeller 672 is rotatably mounted inside the bellows 671 and is fixedly connected to the rotating shaft. A duct 673 and a suction pipe 674 are fixedly mounted on the outer wall of the bellows 671, respectively. The suction pipe 674 is connected to the heat exchange cylinder 61. A drain pipe 65 is connected to the hot water input pipe 4.

[0034] This invention also provides a method for using a cooling machine based on rubber hose processing, the method comprising the following steps: Step 1: When the recycled plastic waste is used to process hoses, the water that has been cooled and heated after molding is fed into the rubber hose cooling housing 1 through the heat exchange component 6 and the hot water inlet pipe 4. Step 2: External air enters the No. 1 dust removal and dehumidification mechanism 7 and the No. 2 dust removal and dehumidification mechanism 8 through the air inlet on the outer wall of the side plate 3. After being dusted and dried by the No. 1 dust removal and dehumidification mechanism 7 and the No. 2 dust removal and dehumidification mechanism 8, it enters the interior of the rubber tube cooling machine shell 1 to cool down the heated cooling water. Step 3: The cooling fan 2 discharges the heat inside the rubber hose cooling housing 1 through the heat dissipation port, and the cooled water is transported to the extruder through the cold water output pipe 5 for the extrusion, cooling and shaping of the rubber hose. The specific process is as follows: During the rubber hose extrusion molding operation, external air is continuously drawn in through the air inlet on the outer wall of the side plate 3 under the action of the cooling fan 2. The air enters the interior of the dust collector 741 through the filter area 744 on the outer wall of the dust collector 741, and the dust in the air is filtered by the filter area 744. When the air passes through the elbow 742, it drives the third impeller 7412 to rotate. The power drives the incomplete helical gear disk 7410 to rotate through the connecting shaft 7411. Since the surface of the incomplete helical gear disk 7410 is only partially provided with teeth, the incomplete helical gear disk 7410 only intermittently drives the bevel gear 749 to rotate. When the first transmission shaft 746 rotates, it synchronously drives the first dust removal component 747 and the second dust removal component 748. As the first dust removal assembly 747 rotates, the push rod 7473 inside the first dust removal assembly 747 rotates until it meets the wedge-shaped drive block 7472. The wedge-shaped drive block 7472 pushes the push rod 7473 to move, which indirectly pushes the push plate 7475 closer to the airbag 7478. The airbag 7478 is continuously squeezed by the pressure plate 7479. The air inside the airbag 7478 is discharged through the narrow and long air nozzle, thereby increasing the blowing force of the air. The air continues to blow on the surface of the filter hole area 744 during the rotation of the bearing box 7477. The dust attached to the surface of the filter hole area 744 is blown off. When the push rod 7473 moves away from the wedge-shaped drive block 7472, the airbag 7478 returns to its original position, ready for the subsequent air blowing operation.

[0035] Clean air enters the clean air pipe 74395 inside the dehumidification assembly 743 through the elbow 742, and is blown into the mounting groove 7434 directly opposite it through the clean air outlet 74396 and the second exhaust port 7437. After being adsorbed by the dehumidification filter element 7435 located in the mounting groove 7434, the moisture in the air is removed, and the clean and dry air enters the rubber tube cooling housing 1 through the first exhaust port 7436 and the corresponding air outlet 78.

[0036] After a period of time, the servo motor 79 is controlled by the controller to rotate at a preset angle, and the second transmission shaft 710 drives the worm gear 711 at multiple positions to rotate. Since the worm gear 711 meshes with the inner cylinder 7432 at multiple positions, the inner cylinder 7432 rotates at a fixed angle relative to the third horizontal plate 75 and the L-shaped plate 76. After each fixed angle rotation, one of the mounting slots 7434 is directly opposite the air outlet 78, and a sealed sliding structure is formed between the outer wall of the inner cylinder 7432 and the inner wall of the air outlet 78. After the servo motor 79 stops running, its output shaft is automatically locked, and it is automatically unlocked when it runs again.

[0037] The cooling water used for processing plastic waste recycling materials into hoses is heated and flows in through heat exchange tube 62. The hot water heats the air inside the heat exchange cylinder 61 through multiple heat dissipation fins 63. As the hot water flows upward through the volute 64, it drives the first impeller 66 to rotate continuously. The power output from the first impeller 66 drives the second impellers 672 on both sides of the volute 64 to rotate at high speed. The suction force generated by the rotation of the second impellers 672 draws the hot air inside the heat exchange cylinder 61 into the air box 671 through the suction pipe 674. The hot air then flows through the air duct 67. 3. The hot air is discharged and sequentially transported through pipes to the hot air pipes 74392 in multiple air supply components 7439. The hot air is transported through multiple hot air exhaust ports 74393 to the spaces of other mounting slots 7434 opposite to the fan-shaped pipe 74394. The hot air enters the dehumidifying filter element 7435 at the corresponding position through the mounting slot 7434. The water vapor adsorbed in the dehumidifying filter element 7435 evaporates under the action of high temperature and is transported to the dehumidification chamber 712 with the airflow. The water vapor is then discharged from the bottom of the rubber tube cooling housing 1 through the moisture exhaust port 9.

[0038] Water cooled by the internal cooling equipment of the rubber hose cooler housing 1 is transported through the cold water output pipe 5 to the cooling section inside the rubber hose extruder to cool and shape the freshly extruded high-temperature rubber hose.
