Description

Technical Field

[0001] The invention relates to the technical field of transfer and discharge hoppers, in particular to a gold mine tailings transfer and discharge hopper. Background Art

[0002] Gold mine tailings are the solid waste remaining after gold is extracted from gold ore. They still contain a certain amount of valuable metals (such as gold and silver) and other recyclable mineral components. With the increasing depletion of mineral resources and the continuous improvement of environmental protection requirements, how to efficiently and environmentally friendly treat gold mine tailings to maximize resource recovery and reduce and harmlessly treat waste has become a major issue facing the gold mining industry. During the gold mine tailings treatment process, the gold mine tailings need to be discharged and transported through a transfer hopper for transportation and treatment.

[0003] During the discharge operation of the transfer hopper, the opening and closing size of the baffle below the hopper needs to be adjusted according to the discharge rate. When the actual production situation requires a relatively small discharge rate, the opening and closing degree of the baffle will also be adjusted accordingly. However, due to the small opening and closing of the baffle, the flow space of the gold tailings becomes relatively narrow during the falling process. The particle characteristics and physical state of the gold tailings themselves cause the mutual force and friction to increase when passing through a narrow channel, which makes it very easy to accumulate. The originally small discharge channel is further compressed, which further reduces the flow rate of the gold tailings. If the accumulation phenomenon is not alleviated and handled in time, it may eventually cause the entire discharge channel to be completely blocked, causing the discharge process to stop. In this way, it is difficult to effectively adjust the discharge rate according to the expected goal, and the discharge rate cannot be stably controlled within the set range, thereby affecting the accuracy and stability of the discharge.
