Multi-shaft variable-speed thermal washing module and thermal washing method thereof

Abstract

The invention relates to a multi-shaft variable-speed thermal washing module and a thermal washing method thereof.The multi-shaft variable-speed thermal washing module comprises a storage assembly and a dehydration assembly and further comprises one or more multi-shaft variable-speed thermal washing machines, and the multi-shaft variable-speed thermal washing machines are connected with the storage assembly and the dehydration assembly. Batch materials are stored in the storage assembly, the materials are put into one or more multi-shaft variable-speed thermal washing machines from the storage assembly during washing, medicament water is added, the multi-shaft variable-speed thermal washing machines replace the functions of thermal washing machines, screws and friction machines, mechanical friction to the materials is large during washing, and the washing effect is greatly improved. The materials which are subjected to thermal washing through the multi-shaft variable-speed thermal washing machine are conveyed into the dewatering assembly to be dewatered, so that separation of washing water and the materials is achieved. According to the multi-shaft variable-speed hot washing module, the equipment investment and the occupied area investment are reduced, meanwhile, the hot washing efficiency is improved, the whole technological process is reasonable, compact and simplified, and the multi-shaft variable-speed hot washing module has great economic popularization value.

Description

technical field [0001] The invention relates to the technical field of plastic recycling and cleaning, in particular to a multi-axis variable-speed hot-washing module and a hot-washing method thereof. Background technique [0002] In the existing technology, during the cleaning process of plastic bottle flakes, the plastic bottle flakes processed by the crushing unit will enter into three hot washing machines respectively through the hot washing feeding screw and the hot washing distributing screw for stirring and hot washing. Each hot washer is a cylinder with a smooth inner wall and a single cleaning blade shaft is arranged in the inner cavity. During the hot washing process, add an appropriate amount of medicinal water into the hot washing machine, and after a certain period of stirring and cleaning with high-temperature medicinal water, the dirt and impurities on the bottle pieces are removed and the paper labels or glue on the bottle pieces are softened. [0003] After...

AI Technical Summary

Problems solved by technology

[0004] The above existing technical solutions have the following defects: the mechanical friction of this design is small during hot washing, and the impurities are difficult to be fully cleaned during the hot washing process; there is a dead angle at the bottom of the screw conveyor, which is easy to accumulate materials, which will affect the next batch of materials. Larger; the number of equipment is large, the volume and space occupied are large, and the equipment cost is large
