[0001] The invention relates to the field of ore dressing shaking tables, in particular to an intelligent shaking table device with a function of returning middlings. Background Art

[0002] The ore dressing shaking table is a commonly used equipment for sorting fine-grained ores. It can make the ore particles move in different directions according to their density and particle size, and spread out in a fan shape along the diagonal starting from the feed trough, and then be discharged along the edge of the bed in sequence. The discharge line is very long and can accurately produce a variety of products of different qualities, such as concentrate, sub-concentrate, middling concentrate and tailings.

[0003] At present, the shaking table beneficiation process is very mature, but the degree of automation is still at a low level. During the shaking table beneficiation process, due to the constant changes in the feed amount, feed concentration, feed particle size and feed grade, the position, width and color of each ore belt on the bed surface will also change accordingly. The operator must observe the characteristic information of these ore belts with the naked eye, and then manually adjust the position of the receiving plate based on experience to achieve the purpose of separation of concentrate, middlings and tailings, and obtain a concentrate grade that meets the requirements. This traditional operation method requires a high frequency of adjustment of the docking plate position, high labor intensity for operators, and unsatisfactory beneficiation indicators.

[0004] Based on the characteristics of high sorting accuracy of shaking table but unstable sorting state, the utility model designs an intelligent shaking table equipment with middling ore return function, which can automatically adjust the position of the receiving plate according to the changes of ore quantity, feed concentration, feed particle size and feed grade in the shaking table beneficiation process, and return the middling ore synchronously for further screening, so as to improve the concentrate output and ore utilization.

[0034] The working principle of the utility model is: when in use, pour the ore crushed slag to be sorted from the feeding trough 7, continuously inject water from the water trough 6, open the transmission device 4, and make the bed surface start to reciprocate and move laterally along the concentrate end 10. At this time, the slag flows from the water outlet 15 to the bed surface 1 along with the water flow, and the concentrate and tailings in the slag are separated under the action of gravity. The concentrate, tailings and incompletely separated intermediate ore form ore bands of different colors on the bed surface 1, wherein the concentrate flows out from the concentrate section 10, and the tailings flows out from the tailings end 11. The industrial camera 12 vibrates synchronously with the bed surface 1, takes pictures of the ore belt in real time, and transmits the picture signal to the central control identification device 13 through the data line 14. The hollow identification device accurately identifies the concentrate belt, tailing belt and medium ore belt through color recognition and other picture recognition functions. After analyzing the picture information, the central control identification device 13 controls the movement of the slide rail 9 through the data line 14, so that the medium ore receiving bucket 8 on the slide rail 9 moves to the corresponding position of the medium ore belt to accurately collect the medium ore. The collected medium ore can be added from the feed trough 7 as slag to be selected and sorted again.
