Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: a crushing shaft structure for a crushing type rotary drum dryer comprises a rotary drum 5 and crushing shafts 1, wherein the number of the crushing shafts 1 is two, the two crushing shafts 1 are connected with an external driving device, the rotating directions of the two crushing shafts 1 are opposite when the two crushing shafts 1 rotate, the crushing shafts 1 are arranged inside the rotary drum 5, the inner side surface of the rotary drum 5 is uniformly and fixedly provided with lifting plates 51, each crushing shaft 1 comprises a coarse crushing section 2, a fine crushing section 3 and a rolling section, the coarse crushing section 2, the fine crushing section 3 and the rolling section are sequentially arranged from the feeding end to the discharging end of the rotary drum 5, the crushing shaft structure for the crushing type rotary drum dryer adopts the double-shaft crushing shaft 1 to crush materials in the rotary drum 5 of the dryer, the materials are prevented from being turned to dead corners by the crushing shafts and being difficult to crush, the crushing effect is improved, and meanwhile, the coarse crushing section 2, the fine crushing section 3 and the rolling section are arranged on the crushing shafts 1, can be to the material of bonding from thick to thin, from big to little carry out the breakage, further improved crushing effect, promoted crushing efficiency, make the material easily disperse to powdered, and then improve stoving effect and drying efficiency, the heat utilization efficiency has also obtained the improvement, is favorable to the energy can be saved, the environmental protection.
