Description

Technical Field

[0001] The utility model relates to the technical field of industrial tools, in particular to a high-strength wear-resistant filter element. Background Art

[0002] Filter element is a professional term for filtering and purifying functions. In order to purify the resources of raw fluids and the simple device for separating resources, filter elements are now mainly used in filtration industries such as oil filtration, air filtration, and water filtration. Melt filter elements are generally used in petrochemical, metallurgical, textile, electronic and pharmaceutical, thermal power and nuclear power industries. Among them, melt filter elements are important equipment for high-speed spinning and spinning fine denier yarns. They are used for continuous filtration of polymer melts to remove impurities and unmelted particles in the melt, so as to improve the spinning performance of the melt and ensure the spinning quality.

[0003] A patent with a publication number of CN212102221U has been searched and disclosed a strong dirt holding capacity melt filter element, including an inlet pipe and a scale prevention device, wherein the upper end port of the inlet pipe is connected to the scale prevention device through a thread, a fixing plate is connected in the middle of the inlet pipe, a filter rod is connected in the middle of the fixing plate, and a water outlet pipe is connected below the filter rod at the lower end surface of the fixing plate. The utility model has a scale prevention device composed of a connecting pipe, a coarse filter screen, an upper limit ring and a lower limit ring, and the upper limit ring and the lower limit ring can well fix the coarse filter screen. The filter screen and the fine filter screen are used to block some impurities by the small holes on the surface of the coarse filter screen and the fine filter screen, so that some impurities remain on the surface of the coarse filter screen and the inside of the connecting pipe. The scale inhibition device can reduce the impurities inside the sewage filtered by the filter rod, thereby reducing the impurities stored inside the filter rod, avoiding the replacement of the filter rod due to excessive impurities, and well ensuring the overall service life of the filter element. This patent only improves the filtering effect by opening small holes in the upper limit ring and the lower limit ring, the filtration is not thorough, and the filter element is not convenient to replace.
