TECHNICAL FIELD
[0001] The present application relates to the technical field of resource recycling, and particularly relates to a waste plastic treatment and utilization equipment. BACKGROUND
[0002] In the field of waste plastic regeneration, in order to improve the recycling quality of waste plastics, a hot washing process is usually used to clean the impurities and printing ink on the surface of the plastic.
[0003] The detailed steps of the plastic hot washing process can be divided into five core links of alkali water pre-washing, agent hot washing, rapid rinsing, clean water rinsing and dehydration drying, which are as follows: alkali water pre-washing: large pieces of plastic are crushed into plastic pieces, and then the plastic pieces are soaked in an alkaline solution (such as a sodium hydroxide aqueous solution) for about 10-15 seconds to preliminarily remove surface oil stains, glue and other impurities. Agent hot washing: after dehydration of the pre-washed plastic pieces, the plastic pieces are sent into a hot washing machine, and after adding cleaning agents, stirring is carried out at 70-90 DEG C to further remove stubborn stains. Rapid rinsing: the plastic pieces are quickly stirred and washed with hot washing liquid at 50-70 DEG C to remove residual cleaning agents and ensure that the surface pH value of the plastic pieces is neutral and the transparency is improved. Clean water rinsing: after dehydration again, the plastic pieces are thoroughly washed with clean water to ensure that there is no chemical residue and the surface is clean. Dehydration and drying: finally, the water content is controlled to be less than or equal to 0.5% by hot air drying (130-150 DEG C), and the regenerated plastic particles are obtained after granulation.
[0004] The agent hot washing is the core step of the plastic hot washing process, and through the cleaning agents and stirring and friction, the impurities and printing ink on the surface of the plastic pieces are chemically and physically cleaned to ensure the quality of the recycled plastic. In the prior art, the main body of the hot washing machine is a cylinder, and a stirring structure is arranged in the cylinder. In use, clean water is first injected into the cylinder, then powder cleaning agents are added into the cylinder, and then the stirring equipment is started to mix the cleaning agents with the solution. In the stirring process, the solution in the cylinder is heated by electromagnetic induction. After the temperature reaches the standard, the plastic pieces are sent into the cylinder for stirring and cleaning. However, in actual application, due to the different densities of the plastic caused by the influence of the molecular chain length, crystallinity, additives and production process, the plastic pieces obtained by recycling are layered in the cylinder due to the different densities. The plastic pieces with larger density sink to the bottom of the solution, and the plastic pieces with smaller density float on the surface of the solution, so that the stirring equipment cannot stir and rub all the plastic pieces during the working process of the hot washing machine, affecting the cleaning quality.
