Description

Technical Field

[0001] The present application belongs to the field of raw material screening devices, and more specifically, relates to a device that has both the functions of loosening plastic granular raw materials and removing metals. Background Art

[0002] Plastic films, plastic garbage bags, etc. mostly use plastic particles as raw materials. In order to improve environmental performance and the utilization efficiency of waste plastics, recycled waste plastics can be used to make plastic particles. A plastic particle iron slag separation device disclosed in the patent document with Chinese Patent Publication No. CN210190248U mentions that in the process of preparing plastic particles, more iron slag or iron powder is often brought in, and these iron slags will seriously affect the quality of injection molding in the later stage. Moreover, according to the patent document with Chinese Patent Publication No. CN112847905A, it mentions that the plastic particle melting equipment for plastic bag processing needs to crush, transport, and melt the plastic particles. Stirring and feeding during the melting process can better melt the plastic particles and achieve better results.

[0003] It can be seen from the above-mentioned patent documents that a certain amount of iron slag, iron filings or iron powder is easily mixed into the plastic particles during the preparation process. These iron slag, iron filings or iron powder mixed into the plastic particle raw materials will affect the quality of injection molding in the later stage. At the same time, when the plastic particles are used, the plastic particles need to be crushed, and the plastic particles are mostly transported in the form of bagged or tubed particles. The extrusion and moisture between the particles may cause adhesion between the plastic particles, affecting the subsequent crushing and re-stirring and melting of the plastic particles. Moreover, it can be seen from the above-mentioned patent documents that the above-mentioned structures are separated and cannot be effectively unified, which increases the purchase quantity of enterprise equipment to a certain extent.

[0035] When the material enters the feeding pipe 2 through the feeding pipe 3, it will be fed to the feeding position of the primary dispersing screen 8 by the action of the spiral feeder 21 driven by the feeding motor 1 in the feeding pipe 2.

The rotating screen 15 is connected to the primary dispersing screen 8 as a whole through a connecting rod, and the primary vibration motor 10 on the primary dispersing screen 8 acts together to move synchronously with the primary dispersing screen 8.

[0037] The secondary vibration motor 14 on the secondary dispersion screen 17 works, causing the secondary dispersion screen 17 to start vibrating, and the material entering the feeding position of the secondary dispersion screen 17 will start to move along the bottom surface of the secondary dispersion screen 17 from the screen body baffle 22 of the secondary dispersion screen 17 until it moves to the screen body outlet 23 of the secondary dispersion screen 17 and falls to the secondary discharge port 13. During the movement of the material in the secondary dispersion screen 17, it will enter the recovery box 18 at the bottom through the dispersion holes 9 on the secondary dispersion screen 17. The plastic powder collected by the recovery box 18 is small and meets the needs of direct use.

This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
