Spiral conveying and drying process

Abstract

The invention provides a spiral conveying and drying process. The spiral conveying and drying process comprises the first step that a feeding assembly is adopted to convey materials cleaned in a cleaning section to a drying section, and the second step that a drying assembly is adopted to dry and then output the materials from the feeding assembly, wherein the feeding assembly comprises a circulation roller, and one end of the circulation roller is suitable for being connected to a material outlet of the cleaning section and receiving the cleaned materials; the inner wall of the circulation roller is provided with a spiral conveying channel and a bucket, a drainage port and a bucket opening are formed in the bucket, and the bucket opening corresponds to a discharge port of the spiral conveying channel; in the rotating process of the circulation roller, the bucket opening receives the materials from the discharge port and dumps the materials into the drying assembly. By the adoption of the spiral conveying and drying process, the materials are dumped into the drying assembly through the bucket opening after moisture in the materials is fully filtered out, and consequently the conveying function and a good drying effect are simultaneously achieved.

Description

technical field [0001] The invention relates to a drying device, in particular to a device for screw conveying and drying materials. Background technique [0002] With the development of society and the progress of the times, people's requirements for the quality of ring mirrors are getting higher and higher, so environmental protection has become a common concern in today's society. The recycling of industrial waste can not only reduce environmental pollution, but also save energy and play a positive role in driving social benefits. [0003] The recycling and reuse of industrial waste first requires decontamination and cleaning of industrial waste. Taking the recycling and reuse of scrap copper as an example, the oil stain attached to scrap copper should be removed first. The traditional method of degreasing copper scrap is manual removal. Oil pollution, like this, not only wastes time, increases labor intensity, and decontamination effect is not good, has influenced the r...

Problems solved by technology

[0006] In this prior art, the drying section is arranged behind the cleaning pipe and inside the screw conveying drum together. This arrangement, on the one hand, will cause the cleaning liquid in the cleaning section to enter the drying section along with the materials, which will affect the The drying effect of the drying section will affect the subsequent drying process and lead to the waste of cleaning liquid. On the other hand, when drying at high temperature, the liquid cannot be discharged in time when it is vaporized, so it is easy to be transported with the screw. The inner wall of the drum contacts and is cooled and liquefied, which leads to poor drying effect; therefore, this method of setting the drying section inside the spiral drum is not advisable

However, if the drying section is simply set outside the screw conveyor drum, the cleaned materials will enter the drying section from the feeding mechanism, and there is also the problem that the cleaning liquid will enter the drying section together with the materials, which will affect the drying effect. Therefore, in order to prevent the cleaning liquid in the screw conveyor drum from entering the drying section, the traditional solution is to set a valve between the screw conveyor drum and the drying section. The valve is closed when cleaning and degreasing, and the valve is opened when cleaning and degreasing is completed. However, when the valve is opened, the cleaning liquid will still enter the drying section with the material, which cannot completely solve the problem of poor drying effect. Therefore, simple control through the valve cannot overcome the cleaning in the screw conveyor drum when the material passes through. The liquid will flow to the drying section, affecting the drying effect of the drying section, and switching the valve back and forth leads to low transmission efficiency
