Material granule screening device of plastic extrusion granulation system

Abstract

The invention relates to the technical field of plastic extrusion granulation, and discloses a material granule screening device of plastic extrusion granulation system. The material granule screeningdevice comprises a base plate, wherein a spring operation cylinder is vertically and upwards fixedly connected to the left and right middle positions of the top of the base plate, a spring is movablyinserted in the spring operation cylinder, a filter box is arranged on the base plate, and vibration motors are fixedly connected to the left and right portions of the top of the filter box, and theleft and right portions of the bottom of the filter box fixedly communicate with discharge hoppers. According to the material granule screening device, cold water in a water tank flows through a coldwater input pipe and a hose and flows into an upper water cooling plate and a lower water cooling plate through the operation of the refrigeration compression circulating pump, and thereby the material granules are cooled, the water source flows back into the water tank for recycling by communicating a connecting pipe with a return pipe; and the indirect water cooling mode is adopted to solve theproblems that air cooling mode of the material granules in the prior art leads to rising of material granules and dust and is not suitable for extensive popularization.

Description

Technical field [0001] The invention relates to the technical field of plastic extrusion granulation, in particular to a material screening device of a plastic extrusion granulation system. Background technique [0002] At present, the main production method of plastic materials is to produce granular raw materials on the extrusion granulation unit. The equipment of the extrusion granulation production line is mainly composed of an extruder, a cooling water tank, a drying fan, a traction mechanism, a pelletizer, and a pellet screening. After the plastic extruded strips are cooled, dried and shredded, the subsequent process is to screen the materials output by the pelletizer, and remove the powder produced during the pelletizing process and the size is too large or too small For the unqualified particles, keep the qualified particles for the next process. [0003] In the prior art, the material particles are cooled by air cooling, which causes the material particles and dust to fly...
