[0028] A frame structure is formed between the fixing ring 2 and the connecting column 3, and an outer sleeve 4 is fixedly connected to the inside of the frame structure, and a cooling structure for cooling the material is arranged inside the outer sleeve 4, and the cooling structure includes an inner sleeve 7 fixedly connected to the inside of the outer sleeve 4, and a cooling pipe 8 is fixedly connected to the inside of the inner sleeve 7, and a feed port 9 is fixedly connected to the top of the cooling pipe 8, and a discharge port 10 extending to the outside of the bottom of the inner sleeve 7 is fixedly connected to the bottom of the cooling pipe 8; an anti-blocking structure for secondary heating of the material is arranged between the inner sleeve 7 and the cooling pipe 8, and the anti-blocking structure includes a fixing rod 11 fixedly connected to the inner side of the inner sleeve 7, and the fixing rod 11 is provided with a plurality of fixing rods 11 which are symmetrically distributed on the inner side of the inner sleeve 7, and the inner ends of the plurality of fixing rods 11 which are symmetrically distributed on the inner side of the inner sleeve 7, and a sealing ring 13 is provided on the fixed frame at the bottom of the inner sleeve 7, and the mounting ring 12 and the sealing ring 13 are fixedly connected to the fixing ... A coil 14 is fixedly connected between the rings 13, the cooling tube 8 and the lower ends of the inner sleeve 7 are both conical structures, and the coil 14 is spirally fitted to the outer side of the lower end of the cooling tube 8, and the inner side of the sealing ring 13 is fixedly connected to the outer side of the lower end of the cooling tube 8, a water inlet 15 is provided at the top of the inner sleeve 7, and the water inlet 15 is tangentially distributed on the outer side of the inner sleeve 7, a plurality of circulation ports 16 are centrally symmetrically distributed at the bottom of the inner sleeve 7, and a plurality of circulation ports 16 centrally symmetrically distributed are located at the top of the sealing ring 13, a main drain port 5 is fixedly connected to one side of the bottom of the outer sleeve 4, and a secondary drain port 6 is fixedly connected to one side of the top of the outer sleeve 4, and a certain space is formed between the outer sleeve 4 and the inner sleeve 7, and the space formed between the outer sleeve 4 and the inner sleeve 7 is communicated with the space formed between the inner sleeve 7 and the cooling tube 8 through the circulation port 16, and the feed port 9 is relatively independent inside;

[0029] First, the mounting strip 1 is mounted on the production device, and the equipment and the production device are fixed by the mounting strip 1. The material will enter the cooling tube 8 from the feed port 9. When the material enters the cooling tube 8, water is introduced into the water inlet 15. The water inlet 15 and the inner sleeve 7 are tangential to each other, so that when the water enters the inner sleeve 7 through the water inlet 15, it will move into the inner sleeve 7 at an angle tangent to the inner sleeve 7, so that when the water enters the inner sleeve 7, it will rotate inside the inner sleeve 7, so that the water improves the efficiency when cooling the cooling tube 8 and the material therein;

Since the water inside the outer sleeve 4 and the inner sleeve 7 is in contact with the inner side of the outer sleeve 4, the water dissipates heat through the outer sleeve 4. At this time, the water inside the outer sleeve 4 and the inner sleeve 7 is lower in temperature than the water inside the inner sleeve 7 and the cooling pipe 8, thereby further cooling the inner sleeve 7 and the water and equipment inside it, and improving the heat dissipation efficiency of the water to the equipment. When the device is in a stopped state, the water inside the device is completely discharged from the device by opening the main drain port 5;

[0031] When the material flows inside the cooling tube 8, as the material moves downward in the cooling tube 8, the material height decreases and the temperature also decreases, making it easy for the material to crystallize when entering the lower end of the cooling tube 8, causing equipment blockage. When the material crystallizes inside the lower end of the cooling tube 8, the coil 14 is energized to form an eddy current inside the coil 14, thereby re-melting the crystallized material inside the cooling tube 8.
