Forged and synthesized main shaft for biomass particle granulating machine

Abstract

The invention relates to a forged and synthesized main shaft for a biomass particle granulating machine, comprising a shaft rod (1), a first shaft head (8) and a second shaft head (8'), wherein the first shaft head (8) and the second shaft head (8') are arranged on a roller atticbase (2) and extrude. The invention is characterized in that the shaft rod (1), the roller atticbase (2), the first shaft head (8) and the second shaft head (8') form an integrated forging piece; the roller atticbase (2) is circular; and the sections of the first shaft head (8) and the second shaft head (8') are fan-shaped. The two shaft heads of the forged and synthesized main shaft for the biomass particle granulating machine of the invention have large connection surfaces with the roller atticbase; the root part of each shaft head is in a circular arc shape and is subjected to an even force, and a large stress is not generated in local parts, thereby ensuring that the two shaft heads can simultaneously transmit moments all the time, so that the two rollers are subject to uniform forces; and since the rollers are subjected to more uniform forces, the damage of machine elements can be greatly reduced.

Description

technical field [0001] The invention relates to the field of biomass particle granulation, in particular to a forging and pressing synthetic spindle for a biomass particle granulator. Background technique [0002] Biomass pellets are one of the emerging renewable energy sources in the world. my country's biomass pellet production and application technology is gradually developing. In the ring die or feeding sleeve of the granulator, there is usually a rotatable pressure roller fixing seat connected to the main shaft, on which there are two pressure rollers that are close to the inner wall of the ring die, and through the pressure roller fixing seat on the The scraper drives the raw material to the designated position, and then squeezed by the pressure roller, the raw material is extruded through the through hole of the ring die. [0003] When the biomass granulator presses materials with high fiber content, such as wood chips and other biomass raw materials, the molding lo...

AI Technical Summary

Problems solved by technology

After the shaft head on one side of the pressure roller seat disk 2 cracks or breaks, its stress system changes fundamentally and cannot bear the due pressure. Therefore, the pressure is transferred to another shaft head, and the shaft bearing force on one side The head overloads the shaft head, causing it to break quickly

[0008] Furthermore, the quality of the material used for the main shaft of this casting structure is not high, which further reduces its performance, and it is difficult to meet the needs of the biological granulator for high strength and high load-bearing capacity of the main shaft. At the same time, the main shaft of the casting molding still has a processing cycle Long, poor precision, time-consuming and material-consuming defects, coupled with frequent damage and replacement, make the production cost high
