Deep waste plastic particle deep purifying and screening device

Abstract

The invention discloses a deep waste plastic particle deep purifying and screening device which comprises a screening machine body, wherein an air blowing hole is formed in the right side wall of a barrel body of a feeding barrel; an air-blowing fan communicates with an inlet in the right side of the air blowing hole; a left-side end opening of a plastic bag inlet is equipped with a light impurity collecting bag in a sealing mode; a supporting mounting frame is fixedly connected below the machine body of the screening machine body; the two sides of a bottom framework of the supporting mounting frame are separately hinged with a rotary cam; a vibrating screening slot is formed in the top end of a post body of a lifting supporting post; a rolling slide wheel can be arranged on the cam periphery of the rotary cam in a sliding mode; and a dust conveying folding tube further communicates with the position above the right side wall of the screening machine body. The deep waste plastic particle deep purifying and screening device avoids the problem that follow-up screening progress is affected as a bag drops; and plastic particles in the vibrating screening slot can be continuously screened, so that a deep screening process for materials which meet specification requirements is realized, and the surrounding environment is protected.

Description

technical field [0001] The invention relates to the related technical field of mechanical equipment, in particular to a deep purification and screening device for waste plastic particles. Background technique [0002] Plastic refers to a material that uses resin (or direct polymerization of monomers during processing) as the main component, plasticizers, fillers, lubricants, colorants and other additives as auxiliary components, and can be flow-formed during processing. Plastic is a synthetic polymer compound that can freely change its shape and style. Plastic is a material that is polymerized by synthesis or condensation reaction using monomer raw materials. It is composed of synthetic resin and fillers, plasticizers, stabilizers, lubricants, colorants and other additives. Its main component is synthetic resin. Among them, Waste plastic granules include recycled plastic granules. Recycled plastic granules are mainly classified according to the different raw materials used ...

Problems solved by technology

Plastic is a material that is polymerized by synthesis or condensation reaction using monomer raw materials. It is composed of synthetic resin and fillers, plasticizers, stabilizers, lubricants, colorants and other additives. Its main component is synthetic resin. Among them, Waste plastic granules include recycled plastic granules. Recycled plastic granules are mainly classified according to the different raw materials used and the characteristics of the processed plastic granules. They are generally divided into first, second, and third grade materials, which require in-depth screening treatment, but The structure and function of the previous screening equipment were simple and single. If a small amount of light impurities contained in the waste, such as plastic film bags or metal impurities, were directly screened without being removed, they would directly damage the mechanical components at the bottom and affect the subsequent screening progress. Subsequent screening It is difficult for the process to achieve the depth in compliance with the specification requirements, resulting in a great reduction in the quality of the screened particles. At the same time, during the long-term high-speed processing process, a large amount of dust generated in the inner cavity diffuses into the surrounding environment, causing serious air pollution, which needs to be solved.
