A biomass fuel drying device

Abstract

The invention discloses a biomass fuel drying device which comprises a drying tank; a heating plate is fixedly mounted at the top end of an inner chamber of the drying tank; a rotating shaft is arranged in the inner chamber of the drying tank; a screw conveying blade wraps the outer wall of the rotating shaft; a separation tank is fixedly mounted on the right side at the bottom end of the drying tank; and a fan and a waste storage tank are fixedly mounted on the left and right sides of the separation tank respectively. According to the biomass fuel drying device, biomass fuel is continuously stirred up and down when moving forwards along the drying tank, so that the biomass fuel can be uniformly stirred and dried; after drying is finished, the biomass fuel falls into the separation tank; and when the biomass fuel falls down, air is blown into a conveying pipeline via the fan, and is then output through air distributing pipes to blow relatively light impurities and dust into the waste storage tank, so that the biomass fuel can be dried continuously. Therefore, the drying efficiency of the biomass fuel is improved.

Description

technical field [0001] The invention relates to the technical field of biomass fuel, in particular to a biomass fuel drying device. Background technique [0002] Due to the increasing demand for energy in society, the fossil fuels as the main energy source are rapidly decreasing. Therefore, looking for a renewable alternative energy has become the focus of public attention. Biomass is the only renewable and directly renewable energy source. Storage and transportation, and energy that can achieve zero CO2 emissions. The currently available biomass fuels mainly include agricultural and forestry waste such as cotton stalks, biomass fuel stalks, yellow straw, and branch wood. The common feature of these fuels is moisture High, high moisture will affect the utilization of biomass fuels. The current biomass fuels need to waste a long time to dry, cannot be dried continuously, and the drying efficiency is low. At the same time, there will be many Impurities and dust can not be cle...

[0002] Due to the increasing demand for energy in society, the fossil fuels as the main energy source are rapidly decreasing. Therefore, looking for a renewable alternative energy has become the focus of public attention. Biomass is the only renewable and directly renewable energy source. Storage and transportation, and energy that can achieve zero CO2 emissions. The currently available biomass fuels mainly include agricultural and forestry waste such as cotton stalks, biomass fuel stalks, yellow straw, and branch wood. The common feature of these fuels is moisture High, high moisture will affect the utilization of biomass fuels. The current biomass fuels need to waste a long time to dry, cannot be dried continuously, and the drying efficiency is low. At the same time, there will be many Impurities and dust can not be cleaned out, such as the patent No. 201520760847.X patent, including material conveying mechanism, feeding hopper, distribution baffle, feeding channel, dial wheel, body, heater, central shaft, dispersion disc , concave guide plate, bottom plate, discharge port, hot air inlet and hot air outlet, although it is easy to use and takes up little space, the impurities mixed in the biomass cannot be cleaned out
