Reclaimed material drying apparatus

Abstract

The invention discloses a drying apparatus difficultly adhering to a device and specially used for producing reclaimed waste asphalt. The apparatus comprises a hot-blast stove and a drying furnace connected with the hot-blast stove, a slide way is arranged in the drying furnace, the inner wall of the drying furnace is provided with heating radiators, the cross section of the drying furnace is rectangular, the slide way is two groups of relatively-interlacing downward-tilting slide plates fixed on the inner wall, and the heating radiators are positioned on the inner wall below the slide plates. The slide way adopts two groups of the relatively-interlacing downward-tilting slide plates, so the contact time of waste asphalt with the slide plates is shortened, thereby the adhesion of the waste asphalt to the slide way is difficult.

Description

technical field [0001] The invention relates to a drying device for recycled materials containing bitumen. Background technique [0002] In repairing the road surface, especially when paving the road surface again, the old road surface will be scooped up mostly, and the old pavement scooped up will be discarded as rubbish. In fact, there is no essential difference between the raw material composition of the old pavement and the new material. It is just that the pavement has been worn out, and there are dents and breakages, but it is a pity to dispose of it as garbage. And this kind of garbage has a large amount and cannot be used for other purposes, which not only increases environmental pollution, but also takes up a lot of garbage sites. The applicant recycles the waste pavement garbage and utilizes it again. In the process of recycling, the waste asphalt pavement must be crushed and heated before it can be used. Since the waste asphalt pavement contains a large amount o...

Problems solved by technology

For this reason, the applicant has previously applied for a "regenerated material drying furnace", the publication number is CN203229855U. There are some problems in the technology, but because the waste asphalt has been sliding on the spiral slideway, when the temperature of the slideway rises to a certain level, the waste asphalt is easy to stick to the spiral slideway, forming agglomerates, and the agglomeration becomes more and more The bigger it is, it will eventually lead to abnormal production

It is difficult to remove the sticky asphalt on the spiral slideway after shutdown, and the spiral slideway can only be scrapped
