Roller dryer with discharging conveying device

Abstract

The invention relates to a dryer, in particular to a roller dryer with a discharging conveying device, and the roller dryer comprises a roller (4), a tail part cover (2), a head part cover (5) and a power mechanism (13), wherein the head part cover (5) and the tail part cover (2) are arranged on two ends of the roller (4), the power mechanism (13) is connected with the roller (4) through a thrust wheel (8), a retainer ring (3) is arranged outside the roller (4), one side of the head part cover (5) is provided with a material inlet (19), and the tail end of the roller (4) on one side of the tail part cover (2) is provided with a material outlet (20). The roller dryer also comprises a helical conveyor (6) with discharging power (7), a power output end of the discharging power (7) is connected with the power input end of the helical conveyor (6), and the material outlet (20) on the tail end of the roller (4) corresponds to an inlet (6-1) of the helical conveyor. The roller dryer is simple in structure, controllable in discharging quality and speed, good in discharging quality and good in drying effect.

Description

technical field [0001] The invention relates to a drying machine, in particular to a drum type drying machine with a discharge conveying device. The invention belongs to the technical field of drying for eliminating liquids from solid materials or articles. Background technique [0002] The tumble dryer is a widely used drying equipment. The main part of the tumble dryer is composed of a rotating cylinder that is slightly inclined to the horizontal line. Materials enter from the cylinder at the higher end, and come out from the cylinder at the lower end under the joint action of the rotating cylinder and gravity. At the same time, the hot air passes into the cylinder and contacts with the material to dry the material. [0003] Chinese patent announcement number CN201772706U discloses a drum dryer, including a drum, the two ends of the drum have different heights, the feeding end of the drum is higher than the discharging end, and the horizontal line of the drum is slight...

AI Technical Summary

Problems solved by technology

Its main disadvantage: the material is in natural contact with the hot air provided by the heat exchange tube, and the drying effect is average

[0004] In addition to the above-mentioned shortcomings, the prior art tumble dryer also has the following defects: the material from the material outlet at the end of the drum flows out directly, and the tumble dryer with this structure flows out by self-flow, and the speed at which the material flows out And the drying humidity is uncontrollable, which makes it difficult to maintain a stable and consistent drying quality and meet the requirements on the one hand, and there are often unqualified products that fail to meet the requirements and need to be reworked

On the other hand, it is not suitable for the material flow rate required by the next process equipment matched with the tumble dryer.
