Description

Technical Field

[0001] This utility model relates to the technical field of polystyrene production equipment, specifically a multi-layer vibrating screen for polystyrene production. Background Technology

[0002] Polystyrene (PS), a commonly used thermoplastic, has a production process that includes key steps such as raw material polymerization, melt extrusion, and granulation. Among these steps, the control of raw material purity and the uniformity of particle size have a significant impact on the performance of the final product (such as impact strength, transparency, and processing fluidity).

[0003] According to the authorized announcement number CN214812468U, a multi-layer vibrating screen for polystyrene production is disclosed, including a device shell, a vibrating structure, screen plates, a motor, baffles, discs, gears, protrusions, hollow rods, connecting rods, a lubrication structure, and a collection structure. Polystyrene particles are screened by setting three screen plates inside the device shell. The motor, located inside the device shell, is started. Gears are fixedly connected to the motor, and the gears mesh with each other, driving the meshing gears on both sides to rotate. A disc is fixedly connected to the other side of each gear, and the disc fixed to the other side of the gear begins to rotate. Protrusions are fixedly connected to the discs, and hollow rods are slidably connected to the outside of the protrusions. The hollow rods slide inside the device shell, sliding within the device shell under the rotation of the protrusions. A connecting rod fixedly connected to the top of the hollow rod slides, and a screen plate is fixed to the other end of the connecting rod. The connecting rod drives the screen plate to slide, achieving repeated movement of the screen plate, allowing the screen plate to vibrate and screen polystyrene particles.

[0004] However, the above-mentioned device still has shortcomings. Although it is equipped with hollow rods and screen plates to realize the movement of the screen plates and screen polystyrene, the polystyrene particles are of different sizes. During the screening process, the inlet and outlet are prone to blockage, resulting in slow material discharge and thus affecting the screening efficiency. Utility Model Content
