Biomass fuel dryer

Abstract

The invention discloses a biomass fuel dryer. The biomass fuel dryer comprises a drying cavity, a resistance heating wire, an insulation layer, a metal shell, a discharge port, a feed port, a supportcolumn, a support plate, a stand column, a rotating motor, a spiral rod, a limiting plate and a discharge hopper; the resistance heating wire is fixed in middle of the outer wall of the drying cavity;the insulation layer is arranged on the outer side of the drying cavity; the metal shell is fixed on the surface of the side, far from the drying cavity, of the insulation layer; in the biomass fueldryer, the drying cavity is heated through the resistance heating wire, and transfers the heat to the surface of a biomass fuel, so that water in the biomass fuel is evaporated, the biomass fuel is dried, and the use is convenient; the resistance heating wire is used for heating, so that the energy is saved, and the environment is protected; and the insulation layer not only can prevent the dryingcavity from exchanging heat with the external, but also can prevent the drying cavity from transferring the heat to the metal shell, so that workers are prevented from scalding, and the safety of thedryer is improved.

Description

technical field [0001] The invention relates to the technical field of dryers, in particular to a biomass fuel dryer. Background technique [0002] Biomass fuel: refers to the burning of biomass materials as fuel, generally mainly agricultural and forestry waste (such as straw, sawdust, bagasse, rice bran, etc.), which is mainly 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 fuel is actually mainly biomass briquette fuel, which uses agricultural and forestry waste as raw materials, and is made into various shapes (such as lumps, granules, etc.) through crushing, mixing, extrusion, drying and other processes. A new type of clean fuel that can be directly burned [0003] However, after the biomass fuel is finished, it will contain a lot of water and c...

Problems solved by technology

[0003] However, after the biomass fuel is finished, it will contain a lot of water and cannot be burned directly. It needs to be dried before it can be used. However, the existing dryers mostly use coal to provide energy, which is not only environmentally friendly, but also a waste of energy. , and most of the existing dryers use the wind to drive the biomass fuel to move in the drying chamber, which is extremely inconvenient to use
