Description

Technical Field

[0001] The utility model belongs to the technical field of plastic particle transportation, and particularly relates to a pneumatic-based plastic particle transportation system. Background Art

[0002] Plastic particles, commonly known as plastic pellets, are raw materials for storing, transporting, and processing plastics in semi-finished form. After the plastic particles are processed, they often need to be transported by a transportation device; according to the patent document with the authorization announcement number: CN208135475U, named "A Transportation Device for Plastic Particle Finished Products", by connecting a second filter screen and a first filter screen inside the loading hopper and the storage box respectively, when the plastic particles fall downward from the inside of the loading hopper during work, the second filter screen can initially filter out a part of the impurities inside the plastic particles, improving the cleanliness of the plastic particles. When the plastic particles move inside the conveying pipe, most of the internal impurities pass through the first filter screen and fall into the storage box, thoroughly removing the impurities inside the plastic particles, making the quality of the plastic particles better, without the need for other cleaning processes, and the processing is simpler; however, there are still the following defects:

[0003] The top of its first filter screen is flush with the inside of the conveying pipe. When the plastic particles pass through the first filter screen, the impurities fall through the first filter screen under the action of gravity. When the wind speed is relatively high or there are more plastic particles, it is difficult to completely drop the impurities in the plastic particles from the first filter screen, thus making it inconvenient to completely remove the impurities in the plastic particles.
