Description

Technical Field

[0001] The present invention relates to the technical field of uranium ore processing, and in particular to a pre-selection and waste disposal system and method for uranium ore processing. Background Art

[0002] At present, the mining of Mianhuakeng uranium mine will inevitably mix with surrounding rocks and interbedded stones, resulting in a decrease in the grade of the ore. With the large-scale development and utilization of uranium resources, high-grade and easy-to-select uranium ores are becoming less and less. In order to solve the problem of economic and efficient development and utilization of Mianhuakeng uranium ore, an intelligent photoelectric concentrator is usually used to establish an image recognition model and a pre-selection and discarding process for the differences in ore properties in different mining areas. The established discarding model is used to conduct exploratory discarding tests on the ore samples prepared in the early stage. On the basis of the exploratory tests, the ore samples are subjected to large-scale industrial tests with the optimal model parameters. According to the pre-selection and discarding of uranium ore, the image recognition model and the pre-selection and discarding process are established. Based on the results of industrial tests, suitable process parameters for on-site waste disposal in Mianhuakeng were proposed, and reasonable ore leaching and transportation processes and equipment types, as well as ore waste disposal methods and equipment types were determined. The results obtained from the tests will be directly applied to the pre-selection and waste disposal production of uranium mines in Mianhuakeng, and will also provide guidance for the uranium ore pre-selection and waste disposal processes of other similar mining enterprises. Waste disposal technology has huge application demands in the field of uranium beneficiation due to its significant and unique advantages, especially for low-grade and complex and difficult-to-select uranium ores. It is of great significance in improving the utilization rate of uranium resources, alleviating crushing and grinding pressure, reducing production costs and reducing ecological and environmental pollution.

[0003] Existing intelligent photoelectric ore dressing machines use sensors to detect and obtain corresponding data based on the physical differences corresponding to different components in the ore. Through machine vision and artificial intelligence technology, they can achieve high-speed, real-time identification and analysis of each ore data, drive high-density spray valves to spray high-pressure gas, and quickly and efficiently separate the ore and waste rock. However, the photoelectric sensor is installed inside the ore dressing machine, making it inconvenient to install and remove the photoelectric sensor. It cannot be installed and removed quickly, causing great inconvenience to the inspection and maintenance of the sensor. Summary of the Invention

[0045] A method for pre-selection and discarding waste for uranium ore processing comprises the following steps:

[0046] Step 1: Ore crushing: crush the ore;

[0047] Step 2: Ore washing: Wash the crushed ore with water;

[0048] Step 3: Ore transportation: transfer the washed ore to the beneficiation rack 1 for transportation;

[0049] Step 4: Pre-selection and discarding: The ore is pre-selected and discarded through the photoelectric sensor 7 on the ore dressing frame 1.

[0050] When installing the photoelectric sensor 7, the photoelectric sensor 7 is plugged into the plug-in hole 64, so that the mounting base 71 is in the mounting groove 63 to realize the positioning of the photoelectric sensor 7. When the ore-selecting frame 1 is working, the electric telescopic rod 14 is started to drive the installation movable plate 2 to move downward and plug it into the installation movable hole 12, that is, the photoelectric sensor 7 is driven to move downward to the working point. When the installation movable plate 2 moves downward, the driving slat 3 will be moved away from the supporting plate frame 13 under the action of the connecting movable rod 29. As the driving slat 3 moves, the matching bearing slat 4 will also be driven to move. At the same time, the matching bearing slat 4 will also move with the installation.

In addition, when the movable matching connecting plate 5 moves, the connecting matching pin 582 and the matching connecting frame 83 will drive the movable locking plate 8 to move downward relative to the installation movable plate 2. As the movable locking plate 8 moves downward, when the photoelectric sensor 7 moves to the bottom of the clamping and fixing frame 82, as the movable locking plate 8 moves downward, the clamping and fixing frame 82 will be pressed on the installation base 71. The photoelectric sensor 7 can be firmly fixed under the action of the clamping fixing frame 82, ensuring the firmness of the installation of the photoelectric sensor 7, and thus ensuring the stability of the photoelectric sensor 7 during operation. When the ore-selecting machine frame 1 is not working, the electric telescopic rod 14 is started to drive the installation movable plate 2 to move upward. At the same time, the movable matching connecting plate 5 is reset under the action of the connecting spring 52, which can drive the photoelectric sensor 7 to reset, so that the photoelectric sensor 7 is moved to the outside of the supporting frame 11, and then the photoelectric sensor 7 is in an unlocked state, which can be quickly disassembled, making it convenient for the inspection and maintenance of the photoelectric sensor 7, which is very convenient.
