A screw conveying degreasing process

Abstract

The invention provides a spiral conveying and degreasing process. In the spiral conveying step, a circulation conveying assembly is arranged and comprises a bucket and a circulation roller, wherein the bucket is fixedly arranged on the inner wall of a spiral conveying roller and provided with a bucket opening; the bucket opening is opposite to a first spiral outlet of a first spiral channel, and a cleaning fluid filtering port is formed in the bucket; one end of the circulation roller penetrates through a spiral conveying outlet of the spiral conveying roller and is located in the spiral conveying roller, and the other end of the circulation roller is connected with a material receiving mechanism in the next process; the end, located in the spiral conveying roller, of the circulation roller is closed, and a receiving port corresponding to the bucket opening is formed in the sidewall, close to the closed end, of the circulation roller and used for receiving materials dumped by the bucket. By the adoption of the spiral conveying and degreasing process, the process that a degreasing portion conveys the materials to a drying section for drying is not affected, and degreasing agents of the degreasing portion can also be prevented from entering the drying section.

Description

technical field [0001] The invention relates to a screw conveying degreasing process, in particular to a process for cleaning and degreasing materials by using a spiral material conveying device. Background technique [0002] With the development of society and the progress of the times, people have higher and higher requirements for the quality of ring mirrors, 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 de...

Problems solved by technology

[0006] In this prior art, the drying section is arranged behind the cleaning pipe part, and is arranged inside the screw conveying drum together, and the cleaning pipe part and the drying section part are not provided with an isolation device. On the one hand, this arrangement causes the cleaning part The cleaning liquid will enter the drying section with the material, which not only affects the drying effect of the drying section, so as to affect the subsequent drying process, but also leads to the waste of cleaning liquid. On the other hand, when drying at high temperature, the liquid When it is gasified, because it cannot be discharged in time, it is easy to contact the inner wall of the spiral conveyor drum and be 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 flows into the drying section to affect the drying effect. In order to prevent the screw conveyor drum from The cleaning liquid inside enters the drying section. The traditional solution is to set a valve between the screw conveying drum and the drying section. The valve is closed when cleaning and degreasing, and the valve is opened when the cleaning and degreasing is completed. However, when the valve is opened, the cleaning The 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 simultaneously solve the problem of material conveying and preventing the cleaning liquid in the screw conveyor drum from flowing to the drying section. two technical questions
