Analysis: Causes and Solutions of iron remover not absorbing iron
In general, it is formed because the magnetic force can not reach because many customers in order to save costs to buy products, product quality is not ideal, so the iron removal effect is not good. In addition to the problem of price and convenience, what are the other reasons for not absorbing iron? How to solve these problems.
1. The effect of the iron sheet near the magnetic field on the iron removal effect is a complex physical process, and the iron sheet around the equipment will affect the iron removal effect after being magnetized.
2, the effect of iron removal temperature rise on the effect of iron removal magnetic field strength is proportional to the current, and the current is inversely proportional to the resistance of the energized coil, the resistance of the energized coil increases with the increase in temperature. Therefore, with the extension of the energized time, the temperature of the energized coil continues to rise, its resistance increases, and the corresponding current will decrease, resulting in the weakening of the magnetic field strength until the dynamic balance is reached. Therefore, the good cooling and heat dissipation effect of the electromagnet is an important factor to keep its field strength from falling sharply. First, choose iron remover with good heat dissipation effect; The second is to arrange the use of double dust collectors in turn, timely cooling, to avoid intermittent iron removal due to the heat of the iron remover when unloading coal.
3, the effect of the thickness of the coal seam on the iron removal effect of the iron removal machine must overcome its own weight, in order to remove the iron filings from the coal on the conveyor belt, the gravity of the coal seam covered on the workpiece, the friction between the layer and the iron parts, the additional attraction of the magnetized iron objects in the magnetic field to the iron parts. The closer the iron sheet is to the magnetic ji of the disk, the greater the suction force, and the smaller the other negative effects. Therefore, the field strength required to prevent the iron sheet from falling is much smaller than the field strength required to suck the iron sheet from the coal seam, so in order to control the temperature rise of the equipment and save energy, metal detectors can be installed before the iron removal. When there is iron filings in the conveyor belt, the metal detector sends a signal to the iron remover, so that the strong magnetism is generated in the iron remover, and the iron filings are sucked up. Under normal circumstances, iron removal equipment only needs to generate a magnetic field to ensure that the iron sheet will not fall off. In order to ensure the reliability of the metal detector, two detectors can be used in parallel as long as one detector detects the iron, the electromagnetic iron remover will immediately produce strong magnetism.
If you want to make the iron removal tool play a better role, you should pay attention to avoid the above reasons. Secondly, you must pay attention to regular cleaning in the usual use process to ensure that the equipment is washed well in the case of iron removal.
