Technical Field
[0001] The utility model relates to the technical field of rotary dryers, in particular to a rotary dryer capable of preventing local hardening. Background Art
[0002] A dryer is a mechanical device that uses heat energy to reduce the moisture content of materials. It is used to dry objects. The dryer heats the material to vaporize the moisture, generally water or other volatile liquid components, in order to obtain a solid material with a specified moisture content. The purpose of drying is to meet the needs of material use or further processing.
[0003] In the existing rotary dryer, powdered or granular materials gradually become agglomerated due to the loss of water during the drying process and adhere to the inner wall of the dryer, resulting in poor drying effect. As a result, the materials need to be crushed again during subsequent use, which increases the complexity.
[0004] Therefore, the problem that the above-mentioned rotary dryer lacks an anti-caking component and the powdered material will clumping into blocks, resulting in reduced drying effect, needs to be solved urgently to improve the use scenario of the rotary dryer. Utility Model Content

[0012] Preferably, the outer surface of the scraper rod is fitted with the inner surface of the drying cylinder, and the fitting surface between the scraper rod and the drying cylinder is designed to be a sharp angle. By designing the fitting surface between the scraper rod and the drying cylinder to be a sharp angle, the contact area between the scraper end and the material and the inner wall of the drying cylinder can be reduced, thereby improving the scraping effect of the scraper rod.

In addition, by setting a crusher rod, when the material turning in the drying cylinder contacts the crusher rod, due to the gravity of the material itself and the small contact area between the material and the crusher rod, the crusher rod will cut the large pieces of material into small pieces, thereby further preventing the material from being compacted and improving the drying effect. This solves the problem that the material of the existing rotary dryer is easily adhered to the inner wall of the dryer to form compaction during operation, resulting in a decrease in the drying effect.
[0016] 2. The drying cylinder is driven to rotate clockwise by the first driving motor, and the crushing assembly is driven to rotate counterclockwise by the second driving motor. The opposite rotation directions can improve the effect of the scraper rod in removing the material adhering to the inner wall of the drying cylinder. By designing the contact surface of the scraper rod and the drying cylinder to be a sharp angle, the contact area between the scraper end and the adhesion point between the material and the inner wall of the drying cylinder can be reduced, thereby improving the scraping effect of the scraper rod.
