Comprehensive force field multithread gravity concentrator

Abstract

The invention discloses a comprehensive force field multithread gravity concentrator. The gravity concentrator comprises a gravity concentrator main body, a comprehensive force field precipitation separation area, a driving device, a rotation device and a pulsation device, wherein the rotation device and the dithering device are arranged at the lower part of the gravity concentrator main body, and enable the lower part of the gravity concentrator main body to form the comprehensive force field precipitation separation area under the combined action of a turbulence fluid field and a pulsation force field; the rotation of the rotation device is driven by the driving device; a feeding opening is formed in the central area at the top of the gravity concentrator; the feeding opening is communicated with the comprehensive force field precipitation separation area at the lower part through a central feeding pipe; an underflow opening is formed in the bottom of the comprehensive force field precipitation separation area; the upper part of the comprehensive force field precipitation separation area is communicated to the overflow dam part at the top of the gravity concentrator main body through an upstream passage encircling the central feeding pipe; baffle board components are uniformly arranged in the upstream passage to form an inclined board settling area. The gravity concentrator has the advantages that the gravity concentrator is high in sorting accuracy, stable and reliable in work, low in energy consumption, and environment-friendly.

Description

technical field [0001] The invention relates to a sorting and grading equipment for minerals, in particular to a high-efficiency gravity sorting, grading and pre-enrichment equipment. Background technique [0002] At present, hydrocyclones, hydraulic grading boxes, spiral chutes and shakers are the main gravity separation equipment for material classification and separation. Due to the single separation force field and the limitation of design principles, this type of gravity separation equipment is used in industrial production. There are the following problems: [0003] 1. The cyclone mainly relies on centrifugal force to achieve classification, and it needs high-pressure delivery of ore pulp. When the thickness of the ore pulp is uneven, it is easy to cause blockage of the bottom flow port and affect the classification efficiency; [0004] 2. The hydraulic classification box realizes the classification of minerals during the static settlement process. Due to the inclusio...

Problems solved by technology

[0003] 1. The cyclone mainly relies on centrifugal force to achieve classification, and it needs high-pressure delivery of ore pulp. When the thickness of the ore pulp is uneven, it is easy to cause blockage of the bottom flow port and affect the classification efficiency;

[0004] 2. The hydraulic classification box realizes the classification of minerals during the static settlement process. Due to the inclusion of minerals in the settlement process and the limitation of the settlement area, the classification efficiency is often not ideal;

[0005] 3. The spiral chute has the advantages of large processing capacity and no energy consumption when sorting coarse-grained minerals, but the separation effect on fine-grained materials is poor;

[0006] 4. The shaker is based on the principle of flowing film mineral processing, through the combined use of reciprocating vibration on the bed surface and vertical and horizontal water flow, the efficient separation of fine-grained minerals is realized, but it has the disadvantages of small processing capacity and unstable operation.

[0007] In short, due to the single fluid force field of the above-mentioned equipment and the limitation of the structure, problems such as gravity separation, poor classification accuracy, unstable operation, and high energy consumption are caused, and it is often difficult to meet the requirements of mineral separation.
