Description

Technical Field

[0001] The present invention relates to the technical field of compacting equipment, and in particular to a mobile compacting device for biomass solid fuel. Background Art

[0002] The biomass solid fuel briquetting device is mainly composed of a feeding mechanism, a crushing system, a stirring device, a briquetting mold and a power system. When working, the raw materials are fed in through the feeding mechanism, crushed by the crushing system and mixed with the additives in the stirring device, and then enter the briquetting mold under the drive of the power system. It is extruded into a high-density block fuel through high pressure. The purpose of its dense processing is to convert loose biomass such as straw and sawdust into solid fuel with small volume, high density and convenient storage and transportation, so as to improve combustion efficiency and reduce environmental pollution. The process flow is: raw material collection → crushing and screening → blending → extrusion molding → cooling and solidification → packaging and storage. The whole process uses mechanical force and appropriate temperature to tightly combine the biomass particles to form a solid fuel product with certain strength and calorific value. When densely processing straw, etc., a mobile briquetting machine is generally used for operation, and the briquetting machine is pulled forward by a traction machine to achieve "harvesting, burning and briquetting".

[0003] The existing application number is CN201020529816.0. This utility model relates to a biomass solid fuel densification processing device. The mobile biomass solid fuel densification processing device includes a crusher, a densifier, and a granulator. The crusher, densifier, and granulator are all mounted on a tractor. The crusher, densifier, and granulator can travel with the tractor (movable as a whole), reaching deep into fields to recover and granulate straw.

[0004] However, in the actual application of mobile biomass solid fuel briquetting machines, since the equipment needs to rely on traction machinery to achieve spatial movement, its working stability is easily affected by the external environment. There are significant technical bottlenecks in the current storage of finished materials. On the one hand, if the briquetting completed materials are directly stored on the storage table of the briquetting machine, they are easily affected by the high-frequency mechanical vibration and continuous impact load during the operation of the equipment, resulting in cracks, breakage and other quality deterioration problems in the molded blocks, which not only reduces the yield, but also affects the uniformity of fuel quality. On the other hand, the method of manual instant transfer of finished products is subject to the operation intensity and reaction speed, resulting in low efficiency of raw material briquetting. Summary of the Invention

[0005] In view of this, the present invention provides a mobile biomass solid fuel compacting processing device, which ensures that the raw materials entering the briquetting mold are uniform and improves the quality of the finished product.
