[0027] Polypropylene improved underwater granulation is a device for completing granulation in water, the melt of polypropylene enters the water chamber after being extruded by the die head, and the particles are cooled and shaped in the water chamber.

The polypropylene powder is extruded by the extruder, granulated in the cutting, and then conveyed to the dewatering machine through the pipeline system for drying. Circulating water is used in the pipeline to convey the particles.
[0028] During the particle conveying process, the particles will gradually move downward due to their own gravity and finally contact the conveying pipeline. At this time, particles may accumulate at the lower part of the conveying pipeline, causing pipeline blockage.
[0029] Referring to Figure 1 and Figure 2 , the particle cooling and conveying channel not easy to block includes a main conveying pipe body 100 and a blowing pipe body 200.
[0030] The main conveying pipe body 100 is a flat tubular member, and the main conveying pipe body 100 is provided with a particle conveying direction, and the main conveying pipe body 100 extends along the particle conveying direction.
[0031] Specifically, in the embodiment, the inner wall of the main conveying pipe body 100 is provided with a plurality of anti-blocking protrusions 110, the plurality of anti-blocking protrusions 110 are equidistantly arranged around the circumferential axis of the main conveying pipe body 100, and the spacing between two adjacent anti-blocking protrusions 110 is less than the particle size of the particles. By arranging a plurality of anti-blocking protrusions 110, the contact area between the main conveying pipe body 100 and the particles is reduced, and more space is provided for the liquid to flow around the particles, so that the particles can be better driven to move in the particle conveying direction.

[0038] Specifically, in the embodiment, the first end portion is provided with the isolation net 400, and the isolation net 400 is detachably connected with the first end portion.
