Description

Technical Field

[0002] Molybdenum flotation tailings slurry concentration technology is a key link to improve the efficiency and economic benefits of molybdenum flotation. Through concentration treatment, the volume and water content of tailings slurry can be significantly reduced, thereby reducing transportation and storage costs and increasing the recovery rate of valuable components. In addition, this technology also helps to reduce environmental pollution and promote green and sustainable mining development.

[0003] In practical applications, the composition, particle size distribution and density of molybdenum flotation tailings slurry vary greatly, so different types of centrifugal equipment are required for centrifugal filtration. For example, tailings slurry with coarser particles may require a centrifuge with strong centrifugal force and sedimentation space, while tailings slurry with finer particles may require equipment with high speed and smaller centrifugal radius.

[0004] Although this approach can meet production needs, it also brings a series of problems. First, the use of multiple centrifugal equipment increases the company's equipment investment and maintenance costs, while increasing the complexity of management. Each device needs to be purchased, installed, debugged and maintained separately, which not only increases the economic burden, but also increases the complexity of management. Secondly, the existence of multiple equipment also increases the difficulty of operating the production process, posing a challenge to the training costs and work pressure of operators.

[0005] Therefore, when selecting and using centrifugal equipment, mining companies need to comprehensively consider factors such as the characteristics of tailings slurry, production requirements, and cost-effectiveness in order to optimize equipment configuration and improve production efficiency and economic benefits.

A connecting sleeve 5 is provided at the center of the upper end of the base 4, and the inner cavity of the base 4 is divided into a first sorting slot 7 and a second sorting slot 9 by a bottom ring 6. A first discharge port 8 is provided at the lowest point of the first sorting slot 7, and a second discharge port 10 is provided at the lowest point of the second sorting slot 9; the feed port 2 is located at the center of the upper end of the centrifugal concentrator housing 1, and is arranged directly opposite to the connecting sleeve 5; the retaining ring 3 is installed in the inner cavity of the centrifugal concentrator housing 1 and is arranged concentrically therewith. The upper end of the bottom ring 6 extends to the lower end of the retaining ring 3; the filter cartridge 11 is connected to the connecting sleeve 5 through a docking sleeve 12, and is placed at the retaining ring 3. A partition frame 13 is provided inside the docking sleeve 12, and a servo motor 14 is installed thereon; the output end of the servo motor 14 is connected to the filter cartridge 11 through a reducer to drive the filter cartridge 11 to rotate and throw out the slurry.

[0026] In addition, the base 4 is sealed and fixed to the centrifugal concentrator housing 1, and the base 4 is integrally designed with the bottom ring 6 and the connecting sleeve 5. The bottoms of the first sorting tank 7 and the second sorting tank 9 are inclined and arranged in a ring shape. Valves are arranged at the first discharge port 8 and the second discharge port 10. The connecting sleeve 5 is connected to the docking sleeve 12 by threads, and a sealing device is provided at the connection. The partition frame 13 is integrally designed with the docking sleeve 12, and the lower end thereof is a rotating handle. The servo motor 14 is fixed to the partition frame 13 by bolts, and its output end is mechanically sealed with the partition frame 13. The upper end of the docking sleeve 12 is a sealing cover, and the output end of the reducer is mechanically sealed with the sealing cover.

[0027] When in use, molybdenum ore flotation tailings slurry is injected into the filter cylinder 11 through the feed port 2, and the filter cylinder 11 rotates to throw out the slurry under the drive of the servo motor 14. The thrown out slurry is further divided by the bottom ring 6 and discharged through the first discharge port 8 and the second discharge port 10.

[0028] Working process: After the device is ready, first start the servo motor 14 to ensure that the filter cartridge 11 is in a rotating state; the molybdenum ore flotation tailings slurry is injected into the filter cartridge 11 through the feed port 2; as the filter cartridge 11 rotates, the slurry is thrown out under the action of centrifugal force, and at the same time, the water is separated through the filtering effect of the filter cartridge 11; the thrown slurry falls on the bottom ring 6 and is further divided into two parts, entering the first sorting tank 7 and the second sorting tank 9 respectively. Subsequently, it is discharged through the first discharge port 8 and the second discharge port 10, and valves are provided at these two discharge ports to control the discharge as needed.

[0029] When replacing the filter cartridge 11, first, stop the operation of the servo motor 14 to ensure that the filter cartridge 11 is no longer rotating; rotate the rotating handle on the docking sleeve 12 to loosen the threaded connection with the connecting sleeve 5. At this time, it is necessary to pay attention to the operation sequence and ensure that the sealing device at the connection is not damaged; after the connection is released, the old filter cartridge 11 can be taken out of the docking sleeve 12; put the new filter cartridge 11 into the docking sleeve 12 and ensure that it is firmly installed. Subsequently, re-tighten the threaded connection between the docking sleeve 12 and the connecting sleeve 5; after replacing the filter cartridge 11, check whether all connections are well sealed, and then restart the servo motor 14 to ensure that the new filter cartridge 11 works normally; the entire replacement process needs to ensure the safety of the operator and avoid any operation that may cause injury. At the same time, when replacing the filter cartridge 11, ensure that the specifications and performance of the new filter cartridge 11 are consistent with the old filter cartridge 11 to ensure the normal operation of the concentration device.
