Biomass crushing rotary drum type drier

Abstract

The invention discloses a biomass crushing rotary drum type drier, which comprises a rack, a motor II and a transmission mechanism, wherein a rotary drum is arranged on the rack and connected with a feeding cover, the motor II and the transmission mechanism; a shoveling plate mechanism is arranged on the inner wall of the rotary drum; a hot medium inlet and a feeding hole are formed in the feeding cover; the hot medium inlet is positioned below the feeding hole; a crushing device is arranged at the inner feeding end of the rotary drum and comprises a crushing shaft; bearings are arranged at two ends of the crushing shaft; one end of the crushing shaft is connected with a motor I through a crushing device transmission mechanism, and the other end of the crushing shaft is connected with the rotary drum and the feeding cover; crushing blades and crushing teeth are arranged on the crushing shaft; and the crushing device is vertical to the axis of the rotary drum. The biomass crushing rotary drum type drier has the advantages of compact and simple structure, reasonable layout, good material drying effect, low base investment and small occupied area, and is particularly applicable to drying of biomass fuels, and the heat exchange rate of a material and heat energy is improved.

Description

technical field [0001] The invention relates to the technical field of drying equipment, in particular to a biomass crushing drum dryer for biomass fuel. Background technique [0002] The rotary dryer is a kind of drying equipment with a wide range of uses. It has the characteristics of large production capacity, continuous operation and wide application range. The particle size of the biomass fuel increases the heat transfer area, which can significantly improve the drying effect of the drum dryer, increase the drying efficiency and reduce the drying cost. At present, most domestic rotary drum dryers are composed of a rotary drum and its rotating device. The inner wall of the drum is equipped with a lifting or distribution type lifting board device. When the drum rotates, the lifting board device also follows the drum. Rotate together and lift the material to be dried in the dryer. With the further rotation of the drum, the material to be dried will be thrown off the lift...
