[0037] After the polypropylene raw material is processed and formed, it needs to be cooled. The operator pours the formed polypropylene into the hollow ball 13 through the funnel 16. The filter disc 17 inside the hollow ball 13 will filter the formed polypropylene. At the same time, the rotating rod 30 is adjusted, and the rotating rod 30 drives the disc 28 to rotate. The disc 28 rotates 90 degrees and is in an open state. The filtered formed polypropylene will fall into the U-shaped tube 4. The operator turns on the fan 10, and the fan 10 blows air into the U-shaped tube 4. The wind cools the formed polypropylene inside the U-shaped tube 4. When the formed polypropylene inside the U-shaped tube 4 needs to be discharged, the vertical pipe 5 is taken out from one end of the U-shaped tube 4, and then the U-shaped tube 4 is rotated to rotate the opening of the U-shaped tube 4 to the bottom, so as to facilitate its discharge for subsequent processing.
