Description

Ore separating assembly, automatic ore separating system and automatic ore separating method Technical Field The invention belongs to the field of mineral separation, and particularly relates to a mineral separation device and a mineral separation method. Background In the field of mineral separation, a shaking table is a gravity mineral separation device widely applied, and the principle of shaking table separation is to utilize the density difference of ore particles on a bed surface, and under the combined action of water flow flushing and differential reciprocating motion of the bed surface, the ore particles are separated according to the density, so that different minerals are separated. Currently, most shaking bed ore-separating operations still rely on manual operation. The operator needs to visually observe the color change of the ore strip on the bed surface (namely the boundary between the ore concentrate strip and the tailing strip) for a long time, and the labor intensity is extremely high. Is influenced by subjective factors such as physiological fatigue, distraction or light change, and the like, and is easy to cause errors in manual judgment, so that the adjustment action is delayed or deviated. In actual production, fluctuations in the feed amount, feed concentration or raw ore grade are normal, which can lead to frequent movements of the parting line position of concentrate and tailings on the bed surface. The manual adjustment of the ore separation plate often has hysteresis, so that part of the concentrate flows into the tailing tank to cause resource waste, or the tailings are mixed into the concentrate tank to reduce the grade of the concentrate. Along with the development of machine vision, after the automatic positioning of boundary line is realized through machine vision, the position of the ore separating plate is changed through a mechanical executing mechanism, and tailings and concentrate flowing out of the edge of the shaking table are separated, so that the problems existing in manual operation can be effectively solved. A similar approach is disclosed in patent application CN111889222 a. The patent has the following problems that 1, a mechanical actuating mechanism needs to automatically move to a boundary line between concentrate and tailings, the length of the tailings from a collecting position is always changed along with the change of the boundary line, the tailings cannot be continuously and accurately guided to a designated position, 2, a plurality of lead screws and actuating mechanisms are adopted to realize unidirectional flow of the tailings, the structure is complex, the mechanical structure is a rigid mechanical structure, because the ore pulp contains a large amount of solid particles, rigid connecting pieces are easy to be blocked due to ore deposit, and 3, when a traditional diversion structure is arranged at an adjusting position, the ore pulp is easy to leak or splash due to the existence of a butt joint gap. Disclosure of Invention The invention aims to solve the technical problems of overcoming the defects and shortcomings in the prior art and providing a mineral separating assembly, an automatic mineral separating system and an automatic mineral separating method, the mineral separation assembly and the automatic mineral separation system can solve the problems of lag and error of manual mineral separation, realize automation of the separation process and accurate mineral separation, and solve the problems of easy blockage and leakage of the traditional rigid mineral separation mechanism. In order to solve the technical problems, the technical scheme provided by the invention is as follows: The utility model provides a divide ore deposit subassembly, includes the ore deposit board, still includes the removal axle and is used for accepting divide the flexible guiding gutter of ore deposit board minute mineral, the both ends export position of flexible guiding gutter is fixed, and is located respectively and is used for collecting concentrate collecting vat top and the tailing collecting vat top that is used for collecting the tailing, the removal axle support is located flexible guiding gutter below and messenger the highest point of flexible guiding gutter is located divide the ore deposit board below, the removal axle with divide ore deposit board synchronous motion, just the removal axle with divide during ore deposit board synchronous motion, the highest point synchronous change of flexible guiding gutter, and the highest point is located all the time divide the ore deposit board below.
