Description

Technical Field

[0001] The utility model belongs to the technical field of polymer slice processing, and in particular relates to an integrated polymer slice processing tank structure. Background Art

[0002] "Slicing" means that a polymer or a mixture of polymers and additives is fed into an extruder for melting, passed through a multi-hole die to form multiple strips, and then cut into pellets with a pelletizer. Cutting can be divided into hot-cut pellets and cold-cut pellets. Hot-cut pellets are cut with a rotating knife immediately after the strips leave the die while being cooled with air or water. At this time, there are no obvious cutter marks around the pellets, and most of them are round pellets; while cold-cut pellets are cut after the strips are completely cooled and then fed into a pelletizer for pelletizing. At this time, cutter marks can be seen on both sides of the pellets, and most of them are flat or oblate.

[0003] The existing slicing processing equipment has a single use and can only meet one of the use requirements, either heating or cooling or extrusion slicing processing. A pipeline connection is required in the middle. Since temperature has a great influence on slicing, it is easy for the slicing raw materials to cause local solidification in the pipeline, the internal part of the equipment, near the pipe mouth, etc. due to temperature fluctuations, resulting in material accumulation and affecting use, or it is necessary to regularly clean the scaling impurities or replace the pipelines that cannot be cleaned; it involves multiple devices and external connecting pipelines, and the cost of use is high, especially for raw materials with higher purity or higher requirements for the storage environment. It may even result in material damage due to local agglomeration of the material. For this reason, we propose a polymer slicing integrated processing tank structure. Utility Model Content
