Abstract

The invention relates to a refluxing type filter connector. The refluxing type filter connector comprises a cyclone separating part and a confluxing separating part, wherein the cyclone separating part mainly comprises a connecting mechanism for injecting fluid into the cyclone separating part, the flow-in fluid is subjected to refluxing by one refluxing mechanism after being filtered primarily, the fluid is subjected to rotating by a main body with a spiral cyclone groove, impurities with different masses are separated, then the fluid is subjected to secondary separation and filtration by a gradually-flared separation component in the confluxing separating part, then the fluid is subjected to third separation by a simple structure, the installation is convenient and the manufacture cost is low.

Description

technical field [0001] The invention relates to a backflow filter joint, in particular to a filter joint which can filter trace impurities and irrelevant mixtures. [0002] Liquid connection for line filtration. Background technique [0003] In many fluid equipments that require high water quality, such as steam drums in boilers, distillers, and some chemical equipment, it is not only often necessary to filter water, but also these equipments often produce Scale, especially at the pipe joints, is particularly prone to blockage due to scaling or dirt accumulation. Whether it is impurities or blockage, it will bring certain safety hazards to these pressure reaction equipment; [0004] Therefore, at the joints of these equipment with high water quality requirements, it is necessary to install some filter components that can not only have a filtering effect, but also ensure a certain fluid permeability; [0005] Among them, ZL201320354014.4 proposes a pipeline filter joint, wh...
