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

Embodiment Construction

[0018] Such as Figure 1-2 Shown, sorting bed 5 is identical with existing shaking table, is provided with ore-feeding tank 7, flushing tank 4 and rifling bar 8 on the bed surface. According to different ore feeding properties, the rifling strips can be turned into grooves, or the rifling strips can be made into corresponding forms. Support 3 is also roughly the same with existing shaking table, all is to make four stakes with concrete, and spring 2 is four, and the lower end is installed on the support, and the upper end is fixed with the sorting bed. The spring is a general helical spring covered with a rubber sleeve.

[0019] The vibrator 6 is a commercially available product, and it is installed on the abdomen of the sorting bed near the end of the mine trough. When installing, first weld a seat plate or frame on the abdomen of the sorting bed, and then install the vibrator to the seat plate or frame go up. The vibration direction of the exciter coincides with or is par...

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...
