Plastic particle screening device and method

Abstract

The invention discloses a plastic granule screening device. The cylinder cover is provided with a feed port, and the upper end of the feed port is connected with a feed hopper, and the lower end of the feed port is connected with a material whose lower end points to a rotating tube. plate, and the lower end of the cylinder is provided with a lower outlet, the cylinder is uniformly provided with air outlets, and the inner wall of the cylinder is provided with a filter, and the lower end of the cylinder is provided with supporting legs. The screening method is as follows: S1 receiving material, S2 feeding and S3 refueling. When the power is turned on, the plastic particles enter from the feeding hopper, and then slide along the material plate to the vicinity of the rotating tube, and fall onto the coarse sieve plate. The motor drives The rotating tube rotates, so that the blowing tube and the bristles can clean and evenly brush the plastic particles, which is convenient for the separation of plastic particles of different sizes. At the same time, with the help of the bristles, there is an external force, and the plastic particles are not easy to stick to the coarse sieve plate. Screening The effect is better, and the plastic particles are blown to the plastic particles through the rotating tube and the blowing tube for continuous drying, which reduces the viscosity, facilitates sieving, and improves the sieving effect.

Description

technical field [0001] The invention relates to the technical field of plastic particle screening, in particular to a plastic particle screening device and a screening method. Background technique [0002] The screening machine screens plastic particles of different sizes through holes of different thicknesses above. There are many similar screening devices on the market. For example, the announcement number is CN204800891U "a screening machine for plastic particles, including hoppers, screening boxes, etc. , is characterized in that: it also includes a small fan, a refrigeration pipe, a dehumidification fan, a coarse filter, a silent box, and a large particle outlet, and a hopper is provided above the screening box, and a small fan is installed below the hopper. A refrigeration pipe is installed outside the screening box, a coarse filter is installed above the inside of the screening box, and a fine filter is installed below the coarse filter, one side of the fine filter is...
