Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic screen changers, in particular to a pre-fixed hydraulic screen changer. Background Art

[0002] The screen changer is used to filter out foreign particles and impurities when the plasticized material flows through the filter. When it is replaced, the filter plate is pushed up and down by the hydraulic cylinder to clean or replace the filter. Although some hydraulic screen changers currently used can meet the use requirements, they still have defects in actual use;

[0003] For example, the patent publication number CN218701089U provides a hydraulic screen changer cleaning device. The patent scrapes the two sides of the filter plate by rotating the auger blade to scrape off the impurities, and then rinses through the multi-nozzle flushing pipe to rinse thoroughly and improve the cleaning effect. The first rotating rod and the second rotating rod are respectively connected to the inner surface of the screen changer through bearings. The surface of the auger blade is closely attached to the outer surface of the two sides of the filter plate, which is convenient for rotating and scraping the surface of the filter plate to scrape off the impurities adhered to the surface;

[0004] However, it is inconvenient to replace the filter screen of this patent. Since the filtering effect of the filter screen decreases after being used for a period of time, it needs to be replaced to improve the filtering effect. When replacing the filter screen of this patent, the filter screen plate needs to be replaced together, which is not only cumbersome to disassemble, but also prone to waste. Improvement is needed. Therefore, a pre-fixed hydraulic screen changing device is now proposed. Utility Model Content
