Description

A continuous rapid prototyping machine for biomass carbon powder and its prototyping method

technical field

The invention relates to the technical field of biomass charcoal powder molding, in particular to a continuous rapid molding machine for biomass charcoal powder and a molding method thereof.

Background technique

Existing molding equipment is mainly used for cold-pressing and hot-pressing molding of biomass raw materials, and small-particle biomass fuel mainly adopts molding method, and molding-type molding machines are divided into flat-mode molding machines and ring-mode molding machines. The advantage of the flat mode molding machine is that the space of the pressing chamber is larger, the large-diameter pressing roller can be used to reduce the particle size requirement of the raw material, and the adaptability to the moisture of the raw material (moisture content 15-25%) is also strong. The disadvantage of the flat mode molding machine is that the output of a single machine is limited, the auxiliary equipment equipped with it is more pelletizing than the ring die, the relative power consumption is more than that of the ring die, and the output is limited by the mold. The advantages of ring mode molding machine are high degree of automation, large single machine output, and suitable for large-scale and industrial development. The disadvantages are large investment scale, serious wear of ring die and pressure roller wearing parts, and lower adaptability of raw materials than flat die. . There are relatively few equipment specially used for bonding and forming of biochar, and they are mainly rotary pressing and molding. The pressure of rotating pressing is relatively fixed and small. In order to increase the density of the formed sample, the forming If the pressure is too high, the mold will be easily worn and the molding efficiency will be reduced. In compression molding, it is difficult to guarantee the uniformity of sample acceptance, and the integrity rate of molded samples is generally low.
