Biomass vertical ring-die pelletizing mechanism

Abstract

The invention discloses a biomass vertical ring-die pelletizing mechanism, comprising a structural body that is composed of a pressing chamber, a press roller assembly and a drive mechanism; the press roller assembly is composed of a roller shaft, three eccentric sleeves and a press roller; the drive mechanism is composed at least of a motor and a transmission mechanism; one side of the structural body is provided with a ring die; an individual space between the ring die and the press roller forms the pressing chamber, the three symmetrical eccentric sleeves are utilized to ensure that equipment is stressed uniformly and rarely damages, the ring die is fixed by a transition flange with fixing and positioning achieved, the transmission mechanism increases torsion while changing the direction, and large equipment can be driven by the small motor; the press roller has no bearing, there is no need to add a lubricant, the problems that traditional bearings are frequently damaged and lubricant usage is high are solved, press roller gap is adjusted and automatically locked without equipment halt, and the fact that manual adjustment is performed with an iron hammer and a wrench after a traditional machine is stopped is avoided.

Description

technical field [0001] The invention relates to the technical field of granulator design, in particular to a biomass vertical ring die granulation mechanism. Background technique [0002] The existing traditional biomass pellet molding machines are all developed from feed machines, and generally adopt the following structure: including a frame and a ring die. The rear power system is connected. There is at least one pressure roller assembly in the ring die. The pressure roller is rotatably installed on the pressure roller fixing mechanism. Driven, continuously passing between the pressure roller and the ring die, under the extrusion of the pressure roller, the material is extruded from the discharge hole, cut off by the divisor cutter device to form a granular material. [0003] Its weak point of above-mentioned technical scheme is: [0004] 1. The press roller assembly (with bearings inside) continues to work in the high-temperature and high-pressure environment of the pr...

AI Technical Summary

Problems solved by technology

[0004] 1. The press roller assembly (with bearings inside) continues to work in the high-temperature and high-pressure environment of the press room, and cannot dissipate heat. It needs to be continuously filled with grease to work normally and the bearings are frequently damaged, so that the equipment cannot work continuously and the cost of use remains high;

[0005] 2. The adjustment of the gap between the pressure roller and the ring die must be carried out in the state of shutdown, and it needs to be turned on and off several times to adjust to the exact position, which is time-consuming and laborious
