Abstract

The invention provides a permanent magnet filter stick, comprising an outer sleeve and segmented permanent magnet sticks in the outer sleeve, wherein all segments of permanent magnet stick are separated and connected by common steel tube segments; gaps exist between the outer sleeve and the segmented permanent magnet sticks as well as between the outer sleeve and the common steel tube segments in a radial direction; two ends of the outer sleeve are closed by iron sheets respectively and sealed by seal rings; the segmented permanent magnet sticks are made from NdFeB (neodymium iron boron); the outer sleeve is a stainless steel pipe; the segment number of the permanent magnet sticks is within the range of 4-29; the length and the diameter of the permanent magnet is 20-100mm and 6-30mm respectively; two magnetic poles of each segment of permanent magnet stick are arranged in a radial direction of the permanent magnet stick respectively; the length and the diameter of a common steel tube is 8-10mm and 6-30mm respectively; and the thickness of the iron sheets is 2-3mm. The permanent magnet filter stick is simple in structure, easy to manufacture, simple and easy in application method, wide in use and suitable for large-scale promotion and application.

Description

technical field [0001] The invention relates to a permanent magnet product and a water treatment device, in particular to a permanent magnet product and its material used in the water treatment device. Background technique [0002] Both iron and steel manufacturing and metal material processing industries must derust metal surfaces. Commonly used derusting methods include high-pressure water jet derusting method, sandblasting derusting method, laser derusting method, acid washing degreasing derusting method, alkali degreasing method Rust removal method, heat treatment method, ultrasonic degreasing and rust removal method, etc., regardless of the surface rust removal method, a large amount of impurities such as rust, dust, grease, etc. will be produced. If the waste liquid containing these impurities is not treated, over time, Liquid will stink and turn black. The traditional methods of separating and removing rust impurities include filtration, precipitation, and cyclone se...
