Description

Technical Field

[0001] The utility model relates to the technical field of regenerated particle screening, in particular to a device for screening regenerated particles of greenhouse waste film. Background Art

[0002] Greenhouse film waste recycled pellets are reusable plastic pellets obtained by recycling, treating, and processing discarded greenhouse film. Greenhouse film is typically made of materials such as polyethylene (PE). As the film reaches the end of its useful life, it becomes agricultural waste. Recycled pellets are made by cleaning, crushing, melting, and granulating the waste film, converting it into new raw materials for the production of various plastic products.

[0003] For example, a waste plastic film recycled particle screening device with publication number CN221112496U comprises: a screening box, a No. 1 material receiving bin is provided at one end of the bottom of the screening box, a No. 2 material receiving bin is provided at the bottom of the screening box on the side of the No. 1 material receiving bin, a material guide mechanism for uniformly discharging plastic particles is provided at the upper end of the screening box, a screen is provided above the No. 1 material receiving bin, and a discharge mechanism for collecting and cleaning plastic particles on the surface of the screen is provided on the screen. By providing the material guide mechanism, it is convenient to uniformly discharge the plastic particles, avoid the accumulation of plastic particles affecting the screening efficiency, and avoid the clogging of plastic particles; by providing the discharge mechanism, it is convenient to collect the plastic particles screened out on the screen, and at the same time, it is convenient to clean the plastic particles stuck in the sieve holes, thereby improving work convenience and avoiding clogging of the screen.

[0004] The above patent proposes that smaller plastic particles fall into the No. 1 receiving bin, and larger plastic particles are located on the surface of the screen. The brush plate moves horizontally to brush the surface of the screen to facilitate brushing out the plastic particles in the sieve holes. However, in actual use, when brushing, the plastic particles will move downward due to the force generated by the brushing, pushing the large-particle regenerated particles into the small-particle regenerated particle receiving bin, which will affect the screening effect of regenerated particles of different diameters and is more inconvenient to use.

[0005] Therefore, we proposed a greenhouse waste film regeneration particle screening device to solve the above-mentioned problems. Utility Model Content
