Drum-type material drying device and using method thereof

Abstract

The invention discloses a drum-type material drying device and a using method thereof and belongs to the technical field of material drying. The drum-type material drying device comprises a rotary drum (1); a feeding hole (11) is formed in one end of the rotary drum (1), and a discharging hole (12) is formed in the other end of the rotary drum (1); a drum supporting and driving device (2) is arranged below the rotary drum (1); the rotary drum (1) is a screen drum or a screen section (13) is at least arranged in the length direction of the rotary drum (1); and a hot water pipeline (3) passes through the length direction inside the rotary drum (1). Not only can the negative-pressure drying be realized, but also the convective drying can be realized, plastic granular materials can be baked or dried by directly utilizing heat of hot water in a granulator cooling water tank, and the drum-type material drying device is reasonable in process, reduced in production cost, wide in application range and particularly suitable for baking or drying materials such as grain crops such as cereals and beans internally containing more water.

Description

technical field [0001] The invention relates to a drying device for granular materials, in particular to a drying device for granulated plastic particles, and also to a drying device for recycling heat energy of a material maker. Background technique [0002] Plastic granulation is an important part in the processing of plastic products. Most plastic raw materials need to be made into granules before they can be used. This technology directly affects the quality of plastic products. At present, the wire and cable industry, pipe industry, profile industry, engineering plastic processing industry, waste plastic processing industry, etc., and the field of polymer material blending all need plastic granulation. The equipment used is: single-screw extrusion granulator, double-screw extruder Screw extrusion granulator, conical twin-screw extrusion granulator, reciprocating extrusion granulator, two-stage extrusion granulator, etc. At present, these processing equipment are used t...

AI Technical Summary

Problems solved by technology

[0003] The first purpose of the present invention is to overcome the defects and insufficiencies of the existing plastic particle drying equipment, such as high energy consumption and the inability to utilize the heat energy of the hot water in the cooling water tank of the granulator, and provide a drum-type material drying device, which can utilize the heat energy of the hot water Heat energy drying, drying materials, lower production costs, good drying effect, wide application range
