Biomass fuel forming and granulating device

Abstract

The invention relates to a biomass fuel forming granulation device which comprises a smashing mechanism used for smashing and stirring biomass raw materials, a drying mechanism used for stirring and drying the biomass raw materials is arranged on the lower side of the smashing mechanism, an extrusion granulation mechanism is installed at the lower end of the drying mechanism, and a base is installed at the lower end of the extrusion granulation mechanism. A material receiving box used for receiving materials is arranged at the upper end of the base and located on the lower side of a discharge port of the extrusion granulation mechanism; the biomass fuel particle production device can solve the following problems in the biomass fuel particle production process in the prior art: the biomass raw material crushing process is relatively simple, so that the biomass raw material crushing effect is relatively poor; no mechanism for stirring biomass raw materials is arranged in the whole process of manufacturing the biomass fuel; and only fixed-point air blowing can be performed, so that the biomass raw materials on the lower side easily block an air flue, the biomass raw materials on the upper side cannot be subjected to air blowing drying, and the drying effect on the biomass raw materials is reduced.

Description

technical field [0001] The invention relates to the field of biomass fuel production, in particular to a biomass fuel molding and granulation device. Background technique [0002] Biomass fuel refers to the burning of biomass materials as fuel, which is generally made of straw, straw, rice husk, peanut husk, corncob, camellia husk, cottonseed husk, etc. through crushing, mixing, extrusion, drying and other processes. Large rod, block or granular, it is a new type of clean fuel that can be used for direct combustion; its performance is better than wood, equivalent to medium bituminous coal, can be directly burned, and the combustion characteristics are significantly improved; at the same time, it has less black smoke and firepower. It has the advantages of prosperous, sufficient combustion, no fly ash, clean and hygienic, and it is easy to transport and store. It can replace coal directly in boilers for power generation or heat supply, and can also be used to solve basic livi...

Problems solved by technology

[0004] However, when the above-mentioned prior art is used to produce biomass fuel, it cannot be stirred during the pulverization process of the biomass raw material, and the process of pulverizing the biomass raw material is relatively simple, resulting in relatively low crushing effect on the biomass raw material. Difference;

[0005] Moreover, the whole process of manufacturing biomass fuel does not have a mechanism for stirring biomass raw materials. If multiple biomass raw materials are used for production, the biomass raw materials that cannot be stirred evenly will affect their subsequent granulation effect. Thereby reducing the quality of biomass fuel;

[0006] Further, when it blows and dries the biomass raw materials, it can only blow at fixed points, and the biomass raw materials fall freely in the feeding pipe, so that the biomass raw materials on the lower side block the air duct, and the biomass raw materials on the upper side cannot be blown. The raw material is blown and dried, which reduces its drying effect on the biomass raw material
