Vertical forming machine for biomass granule fuels

Abstract

The invention relates to a vertical forming machine for biomass granule fuels. Smashed biomass materials can be compressed into the granulated fuels. Two end faces of a circular mold are connected with an external tooth turntable bearing and a tooth-free turntable bearing, respectively; the external tooth turntable bearing is driven to drive the circular mold to rotate, so as to take the biomass materials fed by a distributor into a wedge-shape compressing zone; the two sets of turntable bearings can bear radial load and axial load; the inner circles of the turntable bearings are connected with a frame, so as to form a two-end supporting mode; sliding bearings are arranged at two ends of a press roll shaft; when the clearance of a press roll of the circular mold is adjusted, the deflecting angle of a press roll component is adjusted from the exterior at one side of a forming chamber, the press roll component is positioned and locked on the external two sides of the forming chamber, and the pressed granulated fuels are cut off and then are brought to a discharging hole by a receiving plate. The vertical forming machine for biomass granule fuels has the beneficial effects that the whole machine is compact in structure, the running is stable in working process, the sliding bearings matched with two shaft ends of the press roll work outside the forming chamber and the service life is prolonged.

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
