Direct-heating-type rotary drying machine with automatic opening and closing mechanism

Abstract

The invention relates to a direct-heating-type rotary drying machine with an automatic opening and closing mechanism. The direct-heating-type rotary drying machine is sequentially provided with a feeding device, a dryer body, a material collecting device and a smashing and discharging mechanism from the feeding end to the discharging end. The two ends of the dryer body are coaxially connected with the feeding device and the material collecting device in a rotating mode. The material collecting device and the smashing and discharging mechanism are coaxially arranged. An electric heater body and a transmission gear piece are further fixedly arranged at the outer side of the dryer body coaxially. The drying machine further comprises a driving mechanism. A gear at the power output end of the driving mechanism is engaged with the transmission gear piece. A supporting structure is further arranged at the position, close to the material collecting device, of the dryer body. The smashing and discharging mechanism is composed of a shell and a discharging screw rod located inside the shell. The discharging screw rod stretches into the top of the material collecting device and is connected with a driving motor. A grinding part is arranged at the end of the discharging screw rod and located inside the shell. A proper gap is reserved between the grinding part and the end of the shell. The direct-heating-type rotary drying machine is good in thermal insulation property and capable of reducing production cost.

Description

technical field [0001] The invention relates to a drying device, in particular to a direct heating rotary dryer with an automatic opening and closing mechanism. Background technique [0002] Rotary dryer is a commonly used material drying mechanism. It is used for drying viscous materials. It has high drying efficiency and less material loss. However, the rotary dryers currently on the market have the following defects: poor thermal insulation performance, uneven heating affects product quality, Materials are easy to agglomerate and need to be crushed separately, which wastes labor, greatly reduces production efficiency and increases production costs. Contents of the invention [0003] The purpose of the present invention is to solve the deficiencies of the prior art and provide a direct heating rotary dryer with an automatic opening and closing mechanism. The dryer has good thermal insulation performance, uniform heating, and good product quality. Synchronous crushing sa...
