A frequency conversion control device for iron remover

Abstract

The invention discloses a frequency conversion control device for a de-ironing separator. The device comprises a main circuit and a control circuit; the main circuit comprises a de-ironing separator, a switch QF and a frequency converter of the de-ironing separator; and the control circuit comprises a fuse FU, a stop button SB, a change-over switch SA, a ready indicator light HL, a running indicator light AC, an alternating current contactor KM, an intermediate relay JS, a ready relay KA and a drive relay KA. According to the frequency conversion control device for the de-ironing separator provided by the invention, a rotation speed of the de-ironing separator is adjusted according to a feed back amount for steady operation, so as to effectively enhance the effect and efficiency of iron removal, prolong maintenance cycle, and reduce production and maintenance cost of the equipment.

Description

technical field [0001] The invention relates to a slag fine powder iron removal equipment, in particular to a frequency conversion control device for an iron remover. Background technique [0002] China's iron and steel slag dumps are about 300 million tons, covering an area of ​​30,000 mu. In 2004, my country produced 117 million tons of steel slag, of which 38.19 million tons were steel slag. The stacking of blast furnace slag not only pollutes the environment, but also takes up a lot of space, seriously wasting and polluting land resources. In recent years, in order to improve the efficiency of iron and steel enterprises, reduce the environmental pollution of iron and steel enterprises, and turn waste into treasure, iron and steel enterprises not only consider recycling iron particles in iron and steel slag, but also consider recycling or applying waste blast furnace slag to other industry, and fully realize the economic and social benefits brought about by the comprehen...

Problems solved by technology

In 2004, my country produced 117 million tons of steel slag, of which 38.19 million tons were produced. Blast furnace slag stacking not only pollutes the environment, but also takes up a lot of space, seriously wasting and polluting land resources.

[0004] In the slag differential production process control, the external circulation iron remover has the following disadvantages: if the speed is fast, the iron particles adsorbed on the drum are easily thrown off, and there are few iron particles, so the iron removal effect cannot be achieved

Due to the unclean treatment of iron particles, the grinding roller and grinding disc are seriously damaged, which shortens the surfacing welding time and reduces the effective operation rate of the equipment
