A vertical biomass pellet fuel molding machine

Abstract

The utility model relates to a vertical biomass pellet fuel molding machine, which can compress pulverized biomass materials into pellet pellet fuel. The two ends of the ring die are respectively connected with the outer tooth turntable bearing and the toothless turntable bearing, and the outer tooth turntable bearing is driven to drive the ring die to rotate, bringing the biomass material fed by the distributor into the wedge-shaped compression area; two sets of turntables The bearings can bear radial load and axial load. The inner ring of the turntable bearing is connected with the frame to form a support form at both ends; sliding bearings are installed at both ends of the pressure roller shaft. Adjust the deflection angle of the pressure roller assembly, position and lock the pressure roller assembly on both sides outside the forming cavity, and the pellet fuel after compression molding is cut off and brought to the discharge port by the receiving plate. The beneficial effect of the invention is that the structure of the whole machine is compact, and the operation is stable during operation, and the sliding bearings matched with the two shaft ends of the pressure roller work outside the forming cavity, prolonging the service life.

Description

technical field [0001] The invention relates to a biomass pellet molding machine, in particular to a vertical biomass pellet fuel molding machine. Background technique [0002] Biomass pellet fuel is made of wood chips, crop straw, etc. through mechanical pressing, and is a high-quality clean energy. Biomass molding equipment mainly includes die-roll type, screw extrusion type, plunger type, etc. Among them, the mold roll type has the advantages of high molding rate and continuous production, and is widely used. Die roll type can be divided into two categories: flat mode and ring mode. Flat mode and vertical feeding, the material can easily enter the compression area under the action of gravity, but the mold and pressure roller are prone to uneven wear, and after a period of operation, the gap between the mold and roller is poor. In the ring mode, to facilitate the adjustment of the gap between the mold rolls, most of the press rolls are eccentric shaft type. The bearing ...

AI Technical Summary

Problems solved by technology

Flat mode and vertical feeding, the material can easily enter the compression area under the action of gravity, but the mold and pressure roller are prone to uneven wear, and after working for a period of time, the gap between the mold and roller is poor.

In the ring mode, to facilitate the adjustment of the gap between the mold rolls, most of the press rolls are eccentric shaft type. The bearing between the press roll shell and the press roll shaft is easily polluted by dust particles, and because the press roll bearing is in the material forming cavity, its structural size is limited. , when the extrusion force is too large, the strength of the pressure roller shaft is insufficient, the life of the bearing is very short, and the repair and maintenance time of the equipment is too long
