Abstract
Description
TECHNICAL FIELD
[0001] The utility model belongs to the technical field of plastic particle screening, specifically a plastic particle screening device. BACKGROUND
[0002] Different plastic plates are made by stirring different plastic raw materials, melting after uniform stirring, and then forming. The plastic raw materials need to be crushed and mixed. Some particles of the mixed raw materials are large, which is not conducive to the next melting. Therefore, in production, plastic particles with large particles need to be screened out.
[0003] The specific design and structure of the plastic particle screening device may vary depending on different manufacturers and application requirements, but generally they include the following key parts: feed hopper, screen and discharge port. The feed hopper is the entrance of the plastic particles into the screening device, generally in the shape of a funnel, which can collect and guide the flow of plastic particles into the subsequent screening components. The size and shape of the feed hopper will be designed according to the processing capacity and feeding method of the screening device to ensure that plastic particles can enter the device uniformly and stably. The screen is the core component of the screening device. According to different screening requirements, the screen has different aperture, material and weaving methods. The aperture size determines the maximum size of the plastic particles that can pass through the screen, thereby separating particles of different sizes. Common screen materials include stainless steel, carbon steel, etc. The weaving methods include plain weave, twill weave, etc. After screening, plastic particles of different sizes are discharged from the device through their respective discharge ports. The design of the discharge port should ensure smooth discharge and avoid clogging. At the same time, it can be connected to subsequent conveying equipment or storage containers as needed.
[0004] Currently, when plastic particles are made from recycled plastic, a large amount of dust adheres to the recycled plastic. After the particles are made, the plastic particles will be very dirty. Direct screening will cause dust to float in the air, not only polluting the workplace, but also being inhaled by the operator, causing harm to the body, and long-term inhalation may cause pneumoconiosis and other occupational diseases.
