Embodiment Construction

[0022] The present invention will be further described below in conjunction with the embodiments in the drawings:

[0023] Such as figure 1 As shown, the inclined plate re-flotation separator for fine-grained materials of the present invention is mainly composed of a PID automatic control system, a sorting column, and an overflow tank 5. The sorting column includes a vertical tank body 2, a thin vertical tank body 3 and the inclined trough body 14, the thin vertical trough body 3 and the inclined trough body 14 are connected to the vertical trough body 2 in an irregular letter "Y" structure, and the sorting column is square or round; the vertical trough body 2 The upper end is connected with the inclined trough body 14 and the thin vertical trough body 3. The inclined trough body 14 is provided with a plurality of inclined plates 4, and the angle between the inclined trough body 14 and the horizontal plane is 65°-75°. A number of inclined plates 4 penetrate in parallel in the slo...

Abstract

The invention discloses an oblique-plate gravity-flotation separator for fine materials. The oblique-plate gravity-flotation separator for fine materials comprises a PID control instrument, overflow slots and a separating column; the separating column comprises a perpendicular slot body, a fine perpendicular slot body and an oblique slot body; a plurality of parallel oblique plates with variable quantity are arranged in the oblique slot body; overflow slots are separately formed in the top of the oblique slot body and the top of the fine perpendicular slot body; a feeding hole is formed in the middle upper part of the perpendicular slot body; a flow distribution plate which communicates with an external water inlet tube and a gas tube is arranged on the bottom of the perpendicular slot body; a bottom-flow discharge hole is formed in the bottom center of the slot body of the perpendicular slot body; the fine perpendicular slot body and the oblique slot body are arranged, and the parallel oblique plates are arranged in the oblique slot body, so that shearing effect can be generated on the fine materials, and material grading effect is improved, and therefore, processing capacity of the separator is improved; micro bubbles introduced from the bottom of the perpendicular slot body adsorb extremely fine materials, and the extremely fine materials are collected through the fine perpendicular slot body, so that the problem that the extremely fine materials enter bottom flow and are discharged is solved, separating efficiency is prevented from being affected by the fine materials, and the recovery rate of the fine materials is increased.

Description

Technical field [0001] The invention relates to the technical field of mineral processing equipment, in particular to a fine-grained material inclined plate re-floatation separator with large processing capacity, high separation efficiency and effective separation and recovery of extremely fine-grained materials. Background technique [0002] The operation of separating mineral materials by density difference is called sorting, and the operation of sorting mineral materials by difference in particle size is called classification. In the field of mineral processing, the classification and sorting of fine-grained minerals has always been a research hotspot. At present, the equipment for the classification and separation of fine-grained materials includes small-diameter hydraulic classification cyclones, spiral separators, flotation columns and TBS equipment. [0003] Traditional mineral sorting equipment can classify or sort materials. However, due to the characteristics of mineral m...
