5 Improvements of Our Vertical Disc Dryer
1. Improvements to The Rake Arm
We use 38×5mm thick-walled steel pipe, and insert round steel into the pipe, so that the load-bearing capacity of the rake arm reaches 800kg, thus avoiding the phenomenon of bending deformation.
2. Improvement of The Uneven Surface Of The Disc
The outer retaining ring on the large disc and the inner blanking ring on the small disc is formed by the one-time drum pressing of steel plates. The outer edge of the large disc is pressed into an arc, and the lower surface of the small disc is pressed into an arc, which greatly strengthens the rigidity of the disc and also makes it flatter.
3. The Improvement of The Residual Material on The Disc Surface & Unclean Scraping
It is made of a thick steel plate by hand welding, and the vertical disc surface is punched and looped on the rake arm, and the rotation is more flexible. The middle of the two steel plates is supported by round steel, and the arc transition of the blade surface is highly consistent with the disc surface, thus solving the problem of the material on the disc.
4. Heat Source In/Out
Our company designs the heat source of the disc dryer to be double-in and double-out so that the heat source is distributed more uniformly in and out, and the material on the disc is more fully absorbed, which greatly improves thermal efficiency.
5. Bearing Protection
A hoop-shaped conical pagoda seat is added in the middle of each layer of the material disc, so that when the material on the upper disc surface falls, it slides smoothly along the cone into the lower disc , avoiding the phenomenon that the material falls out of the lower disc and falls into the bottom layer. The design also facilitates maintenance. Bearing protection adopts double-layer sealing of labyrinth and packing, which prevents the occurrence of micro powder damage to the bearing.
