Plastic particle dryer

Abstract

The invention discloses a plastic particle dryer which comprises a material bucket and a material turning device. A bottom partition plate for dividing the material bucket into a hot air chamber and amaterial bin is installed at the bottom of the material bucket, the bottom partition plate is provided with a vent hole for communicating the material bin and the hot air chamber, a hot air pipe externally connected to a hot air dryer is installed on the side wall of the hot air chamber, a feed pipe and an air exhaust pipe are arranged above the material bucket, the feed pipe is connected to a negative pressure loader, and the air exhaust pipe is externally connected to an exhaust fan; and the material turning device includes a drive motor, a transmission shaft, a spiral twisted sheet and aninner tube, the drive motor is fixed on a top cover of the material bucket, the transmission shaft equipped with the spiral twisted sheet goes deep into the material bucket, the inner tube is arrangedoutside the spiral twisted sheet in a sleeving manner, and the inner tube is fixed on the material bucket through an inner tube bracket. By means of the manner, the plastic particle dryer is thoroughin turning in the drying process, has no dead corners, and is uniform in heating, fast in gas heat exchange and high in drying efficiency.

Description

technical field [0001] The invention relates to the field of plastic production, in particular to a plastic particle drying machine. Background technique [0002] Some plastic particles, such as nylon, are easy to absorb moisture in the air during the placement process, resulting in material defects when using the particles for production. Therefore, pre-baking is generally required for such particles. External source baking materials are agitated by a stirrer during the drying process to prevent heat accumulation, but the existing equipment can only realize the transfer of particles on the same plane during the stirring process, and cannot realize the up and down turning of the particles, or the turning speed is relatively slow. Slow, the final drying effect is not uniform enough. Contents of the invention [0003] The technical problem mainly solved by the invention is to provide a drying machine for plastic particles, which can dry uniformly and quickly. [0004] In o...
