Galvanized Line Strong Magnetic Induction
Jun 16, 2017

Galvanized line The material of the roller 5 is made of stainless steel. Galvanized line The surface of the roller is a smooth round surface. The end faces of both ends of the roller are rounded in the form of a cylinder (which is cylindrical). This structure is advantageous for scraping the scraped iron powder , The diameter of the roll is 1 100 mm, considering the permeability of the roller and its own strength, the roll thickness is 8 mm. In the inner cavity of the drum, a permanent magnet 6 which does not rotate with the drum is provided. The magnetic force angle of the permanent magnet is designed to be 230 °, which can maximize the adsorption of iron powder in the fluid while allowing the adsorbed iron powder To scraper 4. The magnetic force of the permanent magnet is close to the outlet as a starting point and is clockwise in the inner cylindrical surface of the roller. The increase in magnetic induction does not affect the rest of the magnetic separator, so the magnetic induction can increase according to the increase of the iron removal rate. The stronger the magnetic induction of the permanent magnet, the better the iron removal effect. The position of the permanent magnet (the starting point of the magnetic force angle) is determined by adjusting the shaft of the roller shaft 11 so that the water of the water withdrawal valve of the water intake valve is at least, and then the positioning shaft is fastened.

The roller is driven by the gear motor through the reducer, Galvanized line the drive is driven by the drive, and the roller is rotated clockwise at low speed, i.e., the countercurrent rotation (the permanent magnet is mounted on the shaft inside the roller and does not rotate with the roller). After repeated experiments, if the speed is too fast, the roller surface adsorption of iron powder contained too much water, waste collection box will soon be filled, is not conducive to the subsequent separation of the iron powder processing; if the roller Cylinder speed is too slow, the magnetic separator of the iron removal rate; when the drum speed of 1 r / min when the best effect. To achieve 1 r / min roller speed, select the rated voltage 220 V, rated power 3.5 kW, the output speed of 20 r / min gear motor and gear ratio of 1/20 of the reducer.

The concave arc-shaped buffer tank 12 is made of stainless steel on the same side of the box body as the inlet 10. As shown in Fig. Concave arc-shaped buffer tank is streamlined, the fluid into the concave arc-shaped buffer tank will not directly impact to the tank, it will not directly impact the iron powder to attract the roller, but the impact of the liquid tank. This design can reduce the speed of the fluid, Galvanized line to prevent the flow due to the large flow and washed away the adsorption of iron powder on the surface of the roller, and will not directly impact the fluid to the tank, reducing the box and the vibration of the connected parts The

The material of the box 9 is made of stainless steel, the bottom of which is circular arc, and the center of the arc is concentric with the roller. The distance between the bottom of the box and the roller should not be too large and the distance is too large. The magnetic force of the permanent magnet in the bottom of the drum can not maximize the adsorption of iron powder flowing through the bottom of the box. Galvanized line To keep the liquid open, The distance between the bottom of the box and the lower surface of the roll is designed to be 40 mm. The box is about 45 mm from the bottom of the roll at the bottom of the arc in the vicinity of the arcuate buffer tank 13 and the outlet 1. The two ends of the roller are 3 mm from the box. The case is provided with a water retaining plate on both sides of the drum in the arc-shaped buffer tank 13 so that the liquid containing the iron powder flowing out of the concave curved buffer tank flows all through the suction zone of the roller, So that the adsorption more thoroughly.

The dewatering device is a plain weave 8 and an ordinary white cloth 7 having one end fixed to the cross bar of the fixing frame 8. As shown in Fig. The mounting bracket 8 is mounted on the box and is located at ten o'clock on the surface of the roller. The cloth 7 is wider than the roll 5 and is free to cover the outer surface of the roller in a clockwise direction, and the cloth 7 covers the length of the roll on the roll of 200 mm. When the magnetic separator is operated, under the combined action of gravity and the slight pressure, Galvanized line friction and adsorption force between the cloth and the roller with the iron, the cloth 7 squeezes the large Part of the water. The iron powder adsorbed on the roll is brought to the scraper as the roller rotates due to the magnetic force.
