The utility model has the following beneficial effects:

according to the utility model, water entering the cylinder sleeve is magnetized through the flowing water gap between the permanent magnet and the magnetizer, then flows out of the space between the outer side of the cylinder sleeve and the inner side of the shell, and finally flows out of the shell through the first water outlet. When water vertically cuts magnetic lines of force at a certain speed, calcium and magnesium ions dissolved in the water obtain induced electric energy, so that the charge state of the ions is changed, the electric attraction among the ions is damaged, the crystallization condition is changed, the generated crystal structure is loose, the tensile and compressive capacities are poor, hard scale with strong bonding force cannot be formed, and loose sludge is discharged along with water flow, so that the purpose of scale prevention is achieved. The magnetized water has certain induction electric energy, and simultaneously, because the expansion coefficients of the steel plate of the conveying pipeline and the water scale are different, old water scales are gradually cracked, the magnetized water continuously invades into the cracks, the adhesive force of the original water scales is damaged, and the old water scales fall off to achieve the effect of removing the water scales. The utility model can magnetize industrial cooling circulating water, further scale prevention and removal are carried out on the conveying pipeline of the industrial cooling circulating water, the structure is simple, and the manufacturing cost is low.

Each permanent magnet of the utility model consists of a plurality of permanent magnet strips, the polarities of the permanent magnet strips are attracted in the transverse direction, and the polarities of the permanent magnet strips are repelled in the longitudinal direction, thereby reducing the magnetic leakage and the magnetic short circuit to the maximum extent and effectively ensuring the magnetic field intensity in the flowing water gap.

The front baffle is arranged at the front end of the corresponding cylinder sleeve, the front baffle divides the shell into two spaces, the front baffle is provided with a second water inlet, and the second water inlet is communicated with the first water inlet of the shell; a rear baffle is arranged at the rear end of the corresponding cylinder sleeve; the front baffle and the rear baffle are connected through a double-end pull rod. The utility model has simple and reasonable structure design and effectively reduces the manufacturing cost on the premise of meeting the industrial circulating water magnetization.
