Embodiment Construction
[0009] The present invention will be further described below in conjunction with the accompanying drawings.
[0010] Such as figure 1 As shown, the system for graded storage of ore slurry by concentration according to the present invention comprises: a primary concentrate storage tank 1, a secondary concentrate storage tank 2, a main electric valve 3, a backup electric valve 4, a secondary concentrate self-flowing ramp Pipe 5, secondary concentrate self-flow pipe 6, concentrate main pipeline 7, concentration meter 8, and primary concentrate outlet pipeline 9. The storage tanks are used to store concentrates of different grades and grades, the first-grade concentrate storage tank 1 is used to store the first-grade concentrate, and the second-grade concentrate storage tank 2 is used to store the second-grade concentrate. The concentration meter 8 is installed on the end pipeline of the concentrate main pipeline 7, within about 50m from the terminal valve 3 or 4, and the detecte...

The invention relates to a system and method for classifying and storing ore pulp slurry by utilizing concentration, used for classification and storage of first-level ore concentrate and low-grade second-level ore concentrate at terminal dehydration stations of mining enterprises. The system comprises a first-level ore concentrate storage groove, a second-level ore concentrate storage groove, a main electrically operated valve, a standby electrically operated valve, a second-level ore concentration automatic flow inclined pipe, a second-level ore concentration automatic flow pipe, a core concentration main pipeline, a concentration meter and a first-level ore concentration outlet pipeline. The method comprises the following steps: transmitting a concentration value which is measured by the concentration meter to a PLC (programmable logic controller); closing the main electrically operated valve if the second-level ore concentration is confirmed so that the ore pulp flows upwards intothe second-level ore concentrate storage groove through the second-level ore concentration automatic flow inclined pipe; and opening the main electrically operated valve if the arrival of second-level ore concentration pulp tail is confirmed or the first-level ore concentration is about to be stored, so that the ore pulp flows downward into the first-level ore concentrate storage groove. According to the invention, the ore pulp at different grades can be subjected to classification storage and hydration operation simply and effectively.
Description
technical field [0001] The present invention relates to the technology of graded storage and dehydration of the multi-stage pulp slurry transported by the pipeline after reaching the terminal station during the transportation of the solid material slurry, in particular to a system and method for graded storage of the pulp slurry by using concentration . Background technique [0002] At present, mining and transportation of high-grade ore has always been the top priority of mining enterprises, which will bring greater economic benefits than mining and transportation of low-grade ore. However, in the face of rising ore prices, low-grade ore stored around mines has also begun to be transported together with high-grade ore by production companies. Therefore, the first grade concentrate and the second grade concentrate are transported to the dehydration station as the final station of the ore through pipelines. However, the dewatering of the primary concentrate and the dewateri...
