Biomass particle fuel forming screening and split charging production line

Abstract

The invention provides a biomass particle fuel forming screening and split charging production line. An elevating mixing device, a forming device, a drying screening device, a split charging device and an elevating conveying device are included. The elevating mixing device comprises a first feeder, two elevators, a raw material bin and a mixing flow dividing machine. Each elevator is internally provided with a first conveying mechanism driven by a first drive motor. A first mixing mechanism is arranged in the raw material bin. A second mixing mechanism is arranged in the mixing flow dividing machine. An extrusion material stirring mechanism and a speed reduction mechanism are arranged in the forming device. The drying screening device comprises a drying machine and a vibration screen. The split charging device comprises a weighing machine, a packaging machine, a conveyor and a control system. A partition mechanism, an iron removal mechanism, a weight sensor and a fixing mechanism are arranged in the weighing machine. The biomass particle fuel forming screening and split charging production line has the characteristics that raw material mixing is uniform and sufficient, running stability is good, the production efficiency is high, the drying effect is good, and the finished product quality and the qualification rate are high.

Description

technical field [0001] The invention relates to the field, in particular to a production line for forming, screening and packaging biomass pellet fuel. Background technique [0002] With the international and domestic society's emphasis on environmentally friendly fuels, biomass pellet fuels produced by using straw, straw, rice husk, peanut shell, corncob, camellia husk, cottonseed husk, branches, sawdust, wood bran and other wastes have become Clean and environmentally friendly fuel pursued by major manufacturers. The production of biomass pellet fuel is mainly divided into two parts: the slicing and crushing of raw materials and the forming, screening and packing of biomass pellet fuel. [0003] The existing biomass pellet fuel forming, screening, and packaging production line mainly has the following problems: first, the existing mixing machine can only mix the biomass raw material powder once, and the raw material powder is easy to mix unevenly, which affects the biomas...

AI Technical Summary

Problems solved by technology

[0003] The existing biomass pellet fuel forming, screening, and packaging production line mainly has the following problems: first, the existing mixing machine can only mix the biomass raw material powder once, and the raw material powder is easy to mix unevenly, which affects the biomass pellet fuel. The second is that most of the existing extrusion molding machines need to use helical gears, the output power of the main shaft is small, the operation is not stable, and the production efficiency is low, and the qualified rate of finished products is low; the third is that the existing drying The machine adopts a spiral structure feeding method, the discharging speed is slow, and it can only be dried on one side, the efficiency is low and the drying effect is not good; the fourth is that the formed biomass pellet fuel still contains a very small amount of iron filings , and the existing sub-packaging device cannot separate the waste products containing a very small amount of iron filings, which affects the quality of the finished biomass pellet fuel
