Description

A multi-layer hydraulic shaking table for mineral processing Technical Field

[0001] The utility model relates to the technical field of mineral processing, in particular to a multi-layer hydraulic shaking table for mineral processing. Background Art

[0002] Ore dressing is the process of crushing and grinding the ore according to the physical and chemical properties of the different minerals in the ore. Then, using methods such as gravity separation, flotation, magnetic separation, and electrostatic separation, the ore is crushed and ground to separate useful minerals from gangue minerals. Furthermore, the various symbiotic and associated useful minerals are separated from each other as much as possible, and harmful impurities are removed or reduced to obtain the raw materials needed for smelting or other industries. Ore dressing can enrich the useful components in the minerals, reduce fuel and transportation consumption during smelting or other processing, and make low-grade ores economically usable.

[0003] Hydraulic shaking tables are commonly used for sorting fine-grained ores. When processing metal ores, they effectively select particles with a particle size range of 3 to 0.019 mm. The outstanding advantage of hydraulic shaking tables is their high sorting precision, enabling the production of high-grade concentrates or waste tailings in a single separation, while also allowing for the simultaneous discharge of multiple products. Arranging multiple layers of shaking tables vertically enables even more refined sorting.

[0004] When the ore separated by the upper shaking table is transported to the next shaking table through the material conveying pipeline, the material splashes easily due to the high flow rate in the pipeline directly hitting the shaking table, which not only causes waste of ore but also pollutes the working area.

The specific implementation methods of the present invention are given in detail in the following embodiments and the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The drawings described herein are used to provide a further understanding of the present invention and constitute a part of this application. The exemplary embodiments of the present invention and their descriptions are used to explain the present invention and do not constitute an improper limitation of the present invention. In the drawings:

[0020] FIG1 is a schematic structural diagram of an embodiment of a multi-layer hydraulic shaking table for mineral processing provided by the present invention;

[0021] FIG2 is a cross-sectional view of the material conveyor in FIG1 . DETAILED DESCRIPTION

[0022] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, and are not used to limit the scope of the present invention.

[0023] The utility model provides a multi-layer hydraulic shaking table for mineral processing. The multi-layer hydraulic shaking table for mineral processing can be used in mineral processing operations to separate desired ores. At the same time, the ore is prevented from splashing outside the shaking table when being transferred between the shaking tables in water.

[0024] It should be noted that the multi-layer hydraulic shaking table for mineral processing of the present invention is used for, but not limited to, mineral processing operations. It can also be applied to other operations requiring a shaking table to separate materials. In this utility model, only mineral processing is used as an example for description. The principles of application in other fields are essentially the same as those used in mineral processing operations, and therefore will not be elaborated here.

[0025] Referring to Figure 1 , the multi-layer hydraulic shaking table used for mineral processing comprises a plurality of shaking table units 1 and a material conveyor 2. The plurality of shaking table units 1 are arranged in a sequentially spaced relationship along the height direction, and adjacent shaking table units 1 are connected via the material conveyor 2. The shaking table units 1 have a screening surface 101 for screening ore and a discharge end 102 for discharging the screened ore. The material conveyor 2 comprises a feed portion 21 and a discharge pipe 22. The feed portion 21 has a material channel with an open upper end. The discharge end 102 of the upper adjacent shaking table unit 1 faces the opening and is used to input the screened ore into the feed portion 21. One end of the discharge pipe 22 is connected to the lower end of the material channel, and the other end of the discharge pipe 22 is parallel to the screening surface 101 of the lower adjacent shaking table unit 1.

[0026] Because the discharge pipe 22 is parallel to the screening surface 101 of the shaker unit 1, the ore contacts the screening surface 101 at a very small angle, significantly reducing ore splash and preventing ore from scattering out of the shaker unit 1, thus avoiding ore waste. Furthermore, the discharge pipe 22 is preferably slightly higher than the screening surface 101. As long as it does not affect the beneficiation operation of the shaker unit 1, the lower the height of the discharge pipe 22 from the screening surface 101, the better. The lower the height, the less ore splashes, preventing it from splashing out of the shaker unit 1.

[0027] In some embodiments, the shaking table unit 1 includes a driving unit 11 and a screening bed 12, and the driving unit 11 is connected to the screening bed 12 in a transmission manner to drive the screening bed 12 to shake. The driving unit 11 can adopt a motor plus a cam connecting rod structure, with the motor as the power source, and the screening bed 12 is driven to shake by the cam connecting rod. The upper surface of the screening bed 12 is the screening surface, and the end of the screening bed 12 away from the driving unit 11 is the discharge end. The screening bed 12 is tilted horizontally by 1° to 5°, and the bed bars are arranged longitudinally on the screening surface 101, and their height decreases from the driving end to the opposite side. The driving unit 11 can make the screening bed 12 have a quick return motion characteristic when it moves forward and approaches the end, that is, a differential motion is formed to screen the ore.

[0028] In some embodiments, the rocking bed unit 1 further includes a bottom plate 13, the driving unit 11 is fixedly mounted on the bottom plate 13, and the screening bed 12 is slidably mounted on the bottom plate 13. The bottom plate 13 is used to support the driving unit 11 and the screening bed 12, and the driving unit 11 drives the screening bed 12 to rock on the bottom plate 13.

[0029] In some embodiments, the shaking table unit 1 further includes a side plate 14, which is fixed to the screening surface 101 and has a notch formed on the side plate 14 facing the discharge end 102. The side plate 14 is used to prevent the ore from accidentally sliding out of the screening bed 12.

[0030] Referring to Figures 1 and 2 , the material conveyor 2 includes a feed section 21 and a discharge pipe 22. The feed section 21 has an elongated rectangular opening adapted to fit the discharge end 102 and is located below the discharge end 102. A protrusion 211 is formed upward at the bottom of the feed section 21. The protrusion 211 is narrow at the top and wide at the bottom, dividing one end of the material passageway into two sections. The material conveyor 2 has two discharge pipes 22, each connecting to the material passageway on either side of the protrusion 211. The discharge pipes 22 are preferably curved to further reduce the flow rate of the ore. They are also arranged toward the side plate 14, where they are used to intercept and stop the ore.

[0031] In some embodiments, the multi-layer hydraulic shaking table further includes a feeder 3 and a discharger 4. The feeder 3 is arranged toward the screening surface 101 of the uppermost shaking table unit 1 and is used to input ore to be processed. The discharge end 102 of the lowermost shaking table unit 1 is arranged toward the discharger 4 and is used to discharge the screened ore.

[0032] Also in order to avoid ore splashing, in a preferred embodiment, the feeder 3 can adopt a structure that is the same as or similar to that of the material conveyor 2 .

[0033] Compared with the prior art, the multi-layer hydraulic shaking table for mineral processing provided by the present invention is provided with a material conveyor between two adjacent shaking table units. The screened ore enters the next shaking table unit through a discharge pipe. The discharge pipe is parallel to the screening surface of the shaking table unit, so that the ore can contact the screening surface at a very small angle, greatly reducing the amplitude of ore splashing, so that the ore will not splash out of the shaking table unit, and avoiding ore waste.

[0034] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed in the present invention should be covered by the protection scope of the present invention.
