Flat-plate bleacher

Abstract

The invention relates to a flat-plate bleacher which comprises a feed hopper and a transmission mechanism. The transmission mechanism is arranged along a horizontal direction, and the head end and the tail end of the transmission mechanism are provided with nonmagnetic transmission drums; annular nonporous transmission belts are sleeved at the peripheries of the nonmagnetic transmission drums; a flat-plate magnetic field system is arranged between the annular nonporous transmission belts and is provided with permanent magnet cylinders which have opposite magnetic polarities and are arranged at intervals; a shower pipe is arranged above the feed hopper, and a feed guide plate is arranged below the feed hopper; waste water pools are arranged on the lower sides of the annular nonporous transmission belts; group control hydraulic shower pipes positioned on the lower sides of the annular nonporous transmission belts are arranged above the waste water pools; and the output ends of the annular nonporous transmission belts are provided with blanking shower pipes, discharge guide plates and loading hoppers. The flat-plate magnetic field system is established, and then magnetic particle substances are rinsed and magnetically separated on a water surface in space dragging and hydraulic flushing and drifting modes below the flat-plate magnetic field system, so the grade of iron ore is enhanced, the cost is low, the production capacity is high and environment protection requirement is easy to meet.

Description

technical field [0001] The invention relates to a flat-plate type rinsing machine, in particular to a technology for increasing the content of chemical components of a material by physical means. The technology improves the grade of magnetic iron ore through rinsing and magnetic separation. Background technique [0002] Iron ore is almost a lean mine in our country, which is a common perception in our country. The domestic steel production is very high, but the ore is controlled by foreign countries, and the import price keeps rising. There is no standard for the price, and the price is set by foreign countries, which is not conducive to the development of our country's economy. my country's iron ore is lean ore, which has two meanings. One is that the content of iron ore is small, but in fact it is not much. The other is that the grade of our ore after passing through the drum water separator is still very low, which is difficult to use for ore smelting. If a better physic...

Problems solved by technology

At present, domestic iron ore particle magnetic separation is basically produced by drum water separator, which not only has low output and low production efficiency, but also produces low-grade iron ore, especially for impurities such as silica and other harmful substances in smelting. Difficult to remove
