Biomass pellet fuel drying and forming device

Abstract

The invention discloses a biomass pellet fuel drying and forming device which comprises a device body, a base is installed at the bottom end of the device body, a driving base is arranged at the top end of the base, a driving motor is arranged on the surface of one side of the driving base, a transmission column is installed at the top end of the driving base, and a grinding disc is installed at the top end of the transmission column. Wherein a discharging port is formed in one side of the bottom end surface of the rolling disc, a storage tank is installed in the middle of the top end of the rolling disc, and a feeding port is formed in the surface of one side of the storage tank. By arranging the corresponding internal roll shaft structures, the opposite rotation structures are formed based on the pressure plate structures and the bottom scraper structures, extruded materials can form structures of the same size under the condition of relative rotation, meanwhile, the internal vibration effect can be reduced through the relative rotation mode, and internal stability is formed.

Description

technical field [0001] The invention relates to the field of biomass particle production, in particular to a drying and molding device for biomass particle fuel. Background technique [0002] Biomass granules are processed by cold compacting of crushed biomass straws, forestry wastes and other raw materials under normal temperature conditions by means of pressing rollers and ring die. The density of raw materials is generally 0.1-0.13t / m 3 , the particle density after molding is 1.1-1.3t / m 3 , which is convenient for storage and transportation, and greatly improves the combustion performance of biomass. The conventional production process mainly includes crushing, drying, rolling forming and other methods. The rotating roller extrudes and scrapes the corresponding shaped particles based on the holes. [0003] However, due to the internal structure of the equipment, the material entering the rolling disc has a large pressure at the bottom of the rolling roller, and the pre...

AI Technical Summary

Problems solved by technology

[0003] However, due to the internal structure of the equipment, the pressure of the material entering the rolling plate is relatively high at the bottom of the rotating roller, and the pressure of the rest is relatively small, which will always cause uneven pressure of rolling, especially in rolling and rolling. When the rotation direction of the scrapers is the same, the extruded shape cannot become a regular three-dimensional structure. At the same time, in the case of adjusting the internal rotation rate, if the internal rotating roller is large, the center of gravity of the overall equipment will easily be affected by torsion. It causes itself to vibrate, and the small rotating roller will cause the base pressure of the platen to be uneven, which will affect the discharge efficiency, so the practicability is not strong
