Non-blocking biomass pellet fuel molding machine

Abstract

The utility model relates to a blockage-free biomass particle fuel molding machine, which belongs to the technical field of biomass particle pressing machinery. It consists of the frame, the support shaft installed on the frame, the ring die installed on the support shaft, the center pressure wheel set in the ring die, the feed trough set at the inlet of the ring die, and the connection set in the feed trough. It is composed of the feeding screw of the feeding motor, the pulley mechanism that drives the ring die to rotate, and the main motor. It is characterized in that the support shaft is a hollow shaft, and the end of the hollow shaft that extends into the ring die is provided with an orifice. , the other end of the hollow shaft is connected with an induced draft fan. The advantage is that the working temperature in the ring die is effectively reduced, the phenomenon of feed blockage and high temperature damage to the pressure wheel assembly is avoided, and the continuous working time and production efficiency of the machine are improved.

Description

technical field [0001] The invention relates to a molding machine for preparing biomass particle fuel, which belongs to the technical field of biomass particle pressing machinery. Background technique [0002] Chinese Patent Publication No. 1836890A discloses a "biomass pellet fuel molding machine", which consists of a frame, a support shaft mounted on the frame, a ring die mounted on the support shaft and a center pressure wheel located in the ring die, It consists of a feeding trough at the feed inlet of the ring die, a feeding shaft connected to the feeding motor shaft in the feeding trough, a feeding screw fixed on the feeding shaft, a driving pulley for driving the ring die and a main motor. The powder is fed into the ring die by the feeding screw, and the biomass pellet fuel is produced under the interaction of the center pressure wheel and the ring die. The disadvantage of this kind of biomass pellet fuel molding machine is that the temperature in the ring die is hig...

AI Technical Summary

Problems solved by technology

The disadvantage of this kind of biomass pellet fuel molding machine is that the temperature in the ring die is high, and the steam formed by the moisture in the powder in the ring die leads to poor feeding or even complete blockage; the high temperature in the ring die also causes the bearing of the center pressure wheel to The components are damaged, the failure rate is high, and the machine must be shut down frequently for maintenance, which seriously affects the working efficiency of the machine
