Description

Technical Field

[0001] This utility model relates to the field of biomass pellet processing technology, and in particular to a crushing roller for processing biomass pellet raw materials. Background Technology

[0002] Biomass pellets are generally made from agricultural and forestry waste, such as rice husks, straw, and sawdust, as raw materials. The process involves crushing, drying, and mixing to produce fuel. Biofuel is a renewable resource. Under normal temperature conditions, crushed biomass straw and forestry waste are cold-pressed and densified using pressure rollers and ring dies. During processing, biomass pellets require crushing. Pairs of crushing rollers are installed inside the crusher, keeping the biomass away from the crushing process. Under heavy-duty crushing conditions, the roller teeth and roller shaft surfaces are prone to fatigue damage, leading to problems such as tooth wear, tooth breakage, and pitting on the roller shaft surface. Most existing crushing rollers are integrally cast parts, which are heavy and large. When the crushing rollers are damaged, disassembly and transportation are very inconvenient, resulting in high maintenance costs and hindering biomass pellet processing. Therefore, we propose a crushing roller for biomass pellet raw material processing. Utility Model Content

[0003] To address the aforementioned problems, this invention provides a crushing roller for processing biomass pellet raw materials. This invention solves the problems of fatigue damage to the roller teeth and roller shaft surfaces, leading to issues such as tooth wear, tooth breakage, and pitting on the roller shaft surface. Existing crushing rollers are mostly integrally cast parts, with relatively large weight and size. When the crushing roller is damaged, it is very inconvenient to disassemble and transport, resulting in high maintenance costs and hindering biomass pellet processing.

[0004] This utility model discloses a crushing roller for processing biomass pellet raw materials, including a shaft, a roller body on the outside of the shaft, a plurality of equidistant connecting rings on the outside of the roller body, a plurality of matrix-arranged mounting grooves on the outside of the connecting rings, wear-resistant teeth fixedly installed in the mounting grooves, a first threaded hole on the middle of the side of the wear-resistant teeth away from the connecting rings, a second threaded hole matching the first threaded hole on the connecting rings, and bolts inserted into the first threaded hole and the second threaded hole.

[0005] In the above scheme, the bolt is provided with an internal hexagon countersunk head.

[0006] In the above scheme, the wear-resistant teeth are provided with limiting blocks at both ends on the side near the connecting ring, and the connecting ring is provided with a connecting groove that matches the limiting blocks.

[0007] In the above scheme, bearings are provided at both ends of the shaft.

[0008] In the above scheme, a wear-resistant layer is provided on the outer side of the wear-resistant tooth.

[0009] In the above scheme, one side wall of the mounting groove is inclined upward.

[0010] The advantages and beneficial effects of this utility model are as follows: This utility model provides a crushing roller for processing biomass pellet raw materials. Wear-resistant teeth can be fixedly installed inside the mounting groove. Bolts are threadedly connected to the first and second threaded holes. The bolts facilitate the installation and disassembly of the wear-resistant teeth and the connecting ring. A limiting block can be inserted into the connecting groove. Through the mutual cooperation between the limiting block and the connecting groove, the wear-resistant teeth can be stably installed inside the connecting groove. The upwardly inclined sidewall of the mounting groove allows the connecting ring to limit the wear-resistant teeth, preventing vertical movement of the wear-resistant teeth. This crushing roller has a simple structure, is easy to operate, has good wear resistance, and allows for easy installation and disassembly of damaged wear-resistant teeth, effectively improving the ease of use of the crushing roller.
