Wrapping type raw material preheating assembly for biomass fuel production

Abstract

The invention discloses a wrapping type raw material preheating assembly for biomass fuel production. The assembly comprises a main body bin, wherein a feeding guide bin is installed at one end of the top of the main body bin, a first conveying belt device and a second conveying belt device are arranged at the top end and the bottom of the interior of the main body bin correspondingly, an electric heating baking lamp is installed in the middle of the top in the main body bin, and a dehumidification preheating assembly matched with the first conveying belt device is arranged at the top in the main body bin. Through cooperative use of the main body bin, the screen drum and the driving device, after biomass fuel raw materials enter the screen drum, the screen drum is driven by the driving device to rotate slowly, the biomass fuel raw materials are screened, and the crushed biomass fuel raw materials fall onto the second conveying belt device through screen holes in the screen drum; and guided by the screen drum, larger wood blocks, stones or iron blocks fall into the second collecting bin, so that the preheating efficiency of the whole preheating assembly is not influenced, and the functionality of the preheating assembly is also improved.

Description

technical field [0001] The invention relates to the technical field of biomass fuel production equipment, in particular to a packaged raw material preheating assembly for biomass fuel production. Background technique [0002] Biomass fuel: refers to the burning of biomass materials as fuel, generally mainly agricultural and forestry waste. The main difference is that it is different from fossil fuels. In the current national policy and environmental protection standards, direct combustion of biomass is a highly polluting fuel, which is only used in large stoves in rural areas and is not allowed to be used in cities. The application of biomass fuels is actually mainly biological Material molding fuel is a new type of clean fuel that can be directly burned by using agricultural and forestry waste as raw materials and making various moldings through crushing, mixing, extrusion, drying and other processes.

Problems solved by technology

[0003] The applicant found through research that currently in the process of biomass fuel production, the biomass fuel raw material is usually directly baked and preheated, which cannot improve the preheating effect. At the same time, the biomass fuel raw material is dehumidified, making the preheat The heated biomass fuel raw materials also need to be dehumidified by a special dehumidification device in the follow-up, which is very inconvenient; and most of the current packaged raw material preheating components for biomass fuel production only have the function of preheating, and cannot be used during the preheating process. Removing larger pieces of wood, stones or iron from biomass fuel raw materials also requires a follow-up process to remove them, which not only increases the footprint of biomass fuel processing equipment, but also reduces the preheating components. functionality; at the same time, when preheating the biomass fuel raw material, the current wrapped raw material preheating component often has a single preheating structure and the preheating effect is not ideal, so it is necessary to slow down the speed of the biomass fuel raw material moving in the equipment. Thereby reducing the preheating efficiency of the whole preheating assembly
