Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand and understand, the present invention is further explained by combining with the specific drawings.

Referring to the barrel body of the spin dryer barrel for recovering plastic particles in fig. 1, in the embodiment, the barrel body 4 of the spin dryer barrel is formed by a barrel wall 1 of the spin dryer barrel and a barrel bottom of the spin dryer barrel, a side wall of the volume cavity corresponding to the barrel wall 1 of the spin dryer barrel is a smooth arc surface, an upper part of the barrel body 4 of the spin dryer barrel is opened, and a sealing cover can be selectively arranged at the opening position; and a rotating shaft support is arranged on the bottom surface of the barrel body 4 of the spin dryer barrel and used for installing a rotating shaft and is connected with an external driving device through the rotating shaft.

The barrel body 4 of the spin dryer barrel is a drum-shaped barrel body, the inner side surface of the barrel wall 1 of the spin dryer barrel is a convex continuous cambered surface, namely the sections of the upper part and the lower part of the barrel body 4 of the spin dryer barrel are smaller than the section of the middle part, the size variation of the sections of the upper part and the lower part of the barrel body 4 of the spin dryer barrel continuously changes from the upper part to the middle part, and the ratio of the height of the barrel body 4 of the spin dryer barrel to the widest part. And be provided with arc fin 3 and concave rib 2 on spin dryer tube barrel wall 1's medial surface, wherein, arc fin 3 is the spiral heliciform shaping of rising on spin dryer tube barrel wall 1, whole arc fin 3 is to volume chamber side protrusion, its section is whole to be the arc, the protruding height is 2.4cm, the width is 4cm, and be provided with indent cambered surface 7 on arc fin 3's lower surface, indent cambered surface 7 is provided with water hole 6 on the extending direction of arc fin 3 interval, it is less than the particle diameter of retrieving plastic granules to cross 6 apertures in the water hole. The section of the concave rib 2 is also arc-shaped, but the concave rib is concave on the side of the spin dryer tube wall 1 back to the volume cavity, and the concave ribs 2 are vertically arranged on the spin dryer tube wall 1 at equal intervals.

The spin dryer barrel body for recycling plastic particles is matched with the shell to be used, when the spin dryer barrel body is used, the spin dryer barrel body 4 is concentrically sleeved in the shell and is assembled with the shell in a clearance mode, and a drain hole is formed in the bottom of the assembly clearance of the shell and the spin dryer barrel body. When the centrifugal drying machine is used, recovered plastic particles with moisture in the previous cleaning process are directly thrown into a volume cavity of a barrel body 4 of the drying barrel after being dried through filtration, the barrel body 4 of the drying barrel is connected with an external driving device and is driven, the barrel body 4 of the drying barrel rotates under the driving of the driving device (generally a motor), the recovered plastic particles in the barrel body 4 of the drying barrel are centrifugally dried, in the drying process, thrown water drops are thrown onto a barrel wall 1 of the drying barrel and are collected through the concave ribs 2, and as the side wall of the volume cavity corresponding to the barrel wall 1 of the drying barrel is a smooth cambered surface, the plastic particles continuously move outwards along the cambered surfaces of the concave ribs 2 under the action of centrifugal force, water in the plastic particles is centrifugally thrown out through the water through holes 6, is discharged to a gap space between the barrel body 4 of the drying barrel and the shell, and is discharged through the water discharge. And the recycled plastic particles are blocked outside the water passing holes 6 due to the structural combination of the concave cambered surfaces 7 and the arc-shaped convex ribs 3, and the water passing holes 6 cannot be blocked under the action of centrifugal force.

In the embodiment, the arc-shaped convex ribs 3 and the concave ribs 2 have the effect of strengthening the barrel wall 1 of the spin dryer barrel, so that the barrel wall 1 of the spin dryer barrel is not easy to be continuously impacted and deformed by recycled plastic particles, and the integral structure can be kept stable; in addition, due to the spiral line structure of the arc-shaped convex ribs 3, the dried recycled plastic particles are integrally pressed downwards in the volume cavity of the barrel body 4 of the spin dryer barrel, so that the gravity center of the barrel body 4 of the spin dryer barrel filled with the recycled plastic particles is lower than that of the spin dryer barrel without the arc-shaped convex ribs 3 and the drum-shaped cavity, and the centrifugal rotation process is more stable.

In addition, as the bottom of the spin dryer tube wall 1 is more worn than the traditional straight wall type spin dryer tube, the bottom side wall of the spin dryer tube wall 1 can be thickened to prolong the service life. And reinforcing ribs can be arranged on the outer side of the side wall of the volume cavity for outer reinforcement.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention.
