Continuous three-cylinder drying machine

Abstract

The invention provides a continuous three-cylinder drying machine. The continuous three-cylinder drying machine comprises a rotary type three-cylinder drying storehouse, a carrier roller supporting frame, a flow guiding pipe, a supporting frame, a heating device, a driving device, a material feeding and air exhausting device and a moving device. The rotary type three-cylinder drying storehouse comprises a shell, a combined type drying storehouse, transmission wheels, a heat conducting working medium and a sealing device. The combined type drying storehouse comprises an inner cylinder, an outer cylinder, a middle cylinder, the supporting frame, a blocking plate, a radiating pipe and a flow guiding plate. A heat energy inlet, a heat energy outlet and an air exhausting port are arranged in the shell. A material discharging port and a material feeding port of the combined type drying storehouse are supported by the carrier roller supporting frame. The transmission wheels are driven to rotate by the driving device. A flange connector on the material feeding port of the heat pipe type three-cylinder drying storehouse is integrated with the flange connector of the material feeding and air exhausting device in a connecting and fixing manner. According to the drying machine, the heat energy of the heating device conducts heating, heat conducting and radiating on materials through the heat conducting working medium, so that the thermal conversion efficiency is high and the lost is low; the materials can be dried continuously, so that the drying efficiency of the materials can be improved and the drying effect of the materials can be optimized.

Description

technical field [0001] The invention relates to a three-cylinder dryer, in particular to a continuous three-cylinder dryer. Background technique [0002] Now on the market, there are drying equipment for materials such as grain, chemical products, coal, gravel, sand, mineral products, pasture, crops, and local specialties. The heat exchange outside the equipment of the three-cylinder dryer on the market is hot air, and the heat exchange The heat efficiency is low, the use of heat energy is one-time, and the heat energy required for drying will increase a lot, which will affect the uneven drying moisture of materials. [0003] The patented continuous three-cylinder vacuum dryer applied by me (patent application number 2016208139322), which includes a rotary three-cylinder drying chamber, an air duct, a roller bracket, a draft tube, a bracket, a vacuum unit, a heating device, a driving device, a vacuum Feeding and discharging device, mobile device. The roller support support...
