Frequency modulating linear motion transverse water current gravity ore dressing bed

Abstract

The invention discloses a frequency modulating linear motion transverse water current gravity ore dressing bed, which comprises a sorting bed, a feeding groove, a flushing water groove and a rifle bar, wherein the sorting bed is supported by springs; the springs are arranged on machine bases; a vibration exciter is arranged on the abdomen of the sorting bed; the included angle between the vibrating direction of the vibration exciter and the be surface of the sorting bed is 0-80 degrees; the amplitude and frequency of the vibration exciter are adjusted by using a stepless speed change motor; four springs are arranged on four machine bases; the vibration exciter can be arranged on a frame of the multilayer sorting bed; the frame is supported on the springs or hung by the springs; and one vibration exciter is used for driving a plurality of sorting beds to vibrate simultaneously. Compared with the conventional swinging bed, the frequency modulating linear motion transverse water current gravity ore dressing bed has the advantage: the motion characteristics are improved. Apart from horizontal swinging force, buoyancy of transverse flushing water and flushing force, vertical vibration force is applied to mineral particles, mineral particle groups move on the bed surface like the jump of a frog, and the loosening and layering of the mineral particles are accelerated remarkably, so that zoning of light and heavy minerals is accelerated, and the treating capability and enrichment ratio of equipment are increased.

Description

technical field [0001] The invention relates to a new type of gravity beneficiation equipment, which uses a frequency-modulated linear motion and a horizontal water flow gravity beneficiation bed. Background technique [0002] The existing shaker is driven by the head of the shaker to make a reciprocating linear motion on the same plane. There is no vertical force acting on the bed body, and the loose layering of minerals on the bed surface is mainly realized by horizontal flushing water flow. Because the effect of lateral water flow is relatively simple, and the size of water flow is often affected by factors such as water pressure, bed surface hydrophobicity, bed surface slope, pulp concentration, and mineral properties, the force is not consistent, and the effect of mineral processing is not very ideal. In addition, the head of the shaking table consumes a lot of electric energy, especially for a single-layer shaking table, which is very uneconomical. Another problem with...

Problems solved by technology

Because the effect of lateral water flow is relatively single, and the size of water flow is often affected by factors such as water pressure, bed surface hydrophobicity, bed surface slope, pulp concentration, and mineral properties, the force is not consistent, and the effect of mineral processing is not very ideal.

In addition, the head of the shaking table consumes a lot of electric energy, especially for a single-layer shaking table, which is very uneconomical. Another problem with the head of the shaking table is that it is more troublesome to maintain. It is necessary to replace the engine oil regularly, and replace the parts that are easy to wear, which will increase the production cost
