Wood bit drying device

Abstract

The invention provides a wood bit drying device which comprises a support, a roller and a stirring mechanism. The roller is fixed to the support, and an air outlet and a feeding port are formed in theupper portion of the roller. A discharging port is formed in the lower end of the roller, and the air outlet is connected with a tail gas treatment mechanism. The tail gas treatment mechanism comprises a cyclone dust collector and an air inducing mechanism, a primary heating mechanism comprises a hot air conveying part, a front disc, a rear disc and a primary barrel. The front disc and the rear disc are fixed into the primary barrel, and the stirring mechanism comprises a motor, a rotary shaft and dividing plates. A plurality of ventilating holes are formed in the rotary shaft along the circumference, and three rows of dividing plates are arranged on the rotary shaft along the circumference. The wood bit drying device has the beneficial effects that by means of the arrangement of the tailgas treatment mechanism, hot air generated in the roller is treated through the dust collector, and environmental pollution is avoided; and wood bits are sequentially subjected to primary preheatingand secondary heating and drying, and the situation that the wood bits are attached to the wall of the roller, and the wood bits are inconvenient to dry is avoided.

Description

technical field [0001] The invention belongs to the technical field of sawdust processing, in particular to a sawdust drying device. Background technique [0002] The sawdust dryer is also called sawdust dryer, sawdust drying furnace, etc. according to the processing of different materials. It is specially designed and manufactured for drying sawdust, small wood chips and veneer. The sawdust dryer adopts a high-temperature rapid drying process and is equipped with a biomass fuel hot blast stove. When the dryer is working, because it will directly discharge the exhaust gas with dust into the air, it will pollute the air and pose a threat to the operator's body; at the same time, the heat exchange efficiency between wood chips and hot air is low during drying, and drying The amount of sawdust coming out is not large. Once too much sawdust is added, it will cause uneven drying and longer drying time. Contents of the invention [0003] The object of the present invention is ...
