Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of twin-screw extruders, in particular to a cooling water treatment device for a twin-screw extruder. Background Art
[0002] The screw in the twin-screw extruder is generally divided into a feed section, a mixing section, a pressure section and a discharge section. It is a conventional processing equipment for highly elastic materials such as plastics and TPE. In the production process, in order to ensure the normal operation of the extruder, a heating system and a cooling system will be set at the same time, so that the temperature of the barrel is constant within a process temperature range required for extrusion plasticization. In order to balance the temperature stability, a cooling water tank is often used to control its temperature according to the temperature through an electronic valve. Since the cooling water needs to enter the extrusion temperature system, the water quality requirements are high, and generally secondary distilled water is required. The traditional cooling device is an internal water tank plus twice distilled water, and a layer of tap water is added outside the internal water tank to cool the circulating cooling water. The internal cooling water is stored in the water tank, which is easy to cause rust, dust and other impurities in the cooling water. The subsequent impact is the blockage of the cooling water pipe or the electromagnetic controller, resulting in excessively high or low local temperatures, affecting normal production, and troublesome cleaning and maintenance. In addition, since secondary distilled water needs to be added every day, it causes a large amount of water and high costs. Utility Model Content
