Description

Technical Field

[0001] This utility model relates to the technical field of slurry treatment equipment, and in particular to a high-nickel matte slurry cyclone classification device. Background Technology

[0002] High-nickel matte slurry classification typically requires a submersible pump to provide pressurized feed, allowing the slurry to enter a hydrocyclone at a certain flow rate. Centrifugal force then separates the solid particles in the slurry into overflow and sediment based on particle size. Simultaneously, the high shear stress from the hydrocyclone breaks down particle aggregation, further refining the slurry and greatly benefiting high-nickel matte slurry classification. Although operating multiple hydrocyclones simultaneously consumes significant energy, it offers high classification efficiency and large flow rates. Maintaining stable feed pressure and flow rate is crucial for ensuring consistent high-nickel matte classification performance using this type of device.

[0003] However, the existing high-nickel matte slurry classification devices have the following problems: the large number of hydrocyclones required necessitates the installation of numerous pipelines, which takes up a lot of space. Furthermore, the single submersible pump supplies slurry to multiple hydrocyclones, requiring simultaneous connection to multiple slurry feed pipes. This results in significant fluctuations in the slurry flow rate within the pipes, affecting the slurry velocity entering the hydrocyclones. Consequently, production and management costs increase, and classification efficiency remains low. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a high-nickel matte slurry cyclone classification device.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: A high-nickel matte slurry cyclone classifier includes: The feed tank has a feeding assembly at the bottom; The hydrocyclone and the second hydrocyclone are located on one side of the feed tank and are connected to the feed tank through connecting pipes. The bottom outlets of both the hydrocyclone and the second hydrocyclone are connected to the sedimentation tank, and the top outlets are connected to the overflow tank.

[0006] The feeding assembly includes: The slurry feed pipe is connected at its outlet to the bottom of the feed tank. The submersible pump is installed at the inlet end of the slurry feed pipe.

[0007] The bottom of the sedimentation receiving tank is equipped with a sedimentation feeding pipe; the bottom of the overflow receiving tank is equipped with an overflow feeding pipe.

[0008] The hydrocyclone and the second hydrocyclone are respectively installed on the sedimentation receiving tank via support frames.

[0009] Both the sedimentation tank and the overflow tank are mounted on a fixed plate.

[0010] The top outlets of the hydrocyclone and the second hydrocyclone are connected to the overflow receiving pool via overflow pipes and overflow receiving pools, respectively.

[0011] The beneficial effects of this utility model are: 1. This utility model relates to a high-nickel matte classifying device with a compact structure, small footprint, large processing capacity, and high classification efficiency. The device is simple to set up, and the number of hydrocyclones used can be flexibly adjusted according to production conditions. If a hydrocyclone malfunctions, it can be easily replaced, serving as a backup for each other, facilitating maintenance. This device requires only a single slurry feed pipe to supply slurry to the feed tank, reducing the number of pipes needed and ensuring stable flow in the pipes. It solves the problems of increased production and management costs caused by multiple hydrocyclones operating simultaneously, as well as the low classification efficiency of high-nickel matte classifying devices. 2. This utility model connects the feed tank to multiple hydrocyclones via a connecting pipe, requiring only a single slurry feed pipe to supply slurry to the feed tank, thus reducing the number of pipes required for the operation of multiple hydrocyclones. By increasing the power of the submersible pump, the instantaneous flow rate of the slurry in the slurry feed pipe is increased, and the supply from a single slurry feed pipe ensures a stable flow rate in the pipe. The slurry is simultaneously supplied to multiple hydrocyclones for stable operation, thereby improving the classification efficiency of high-nickel matte slurry. This solves the problems of increased production and management costs due to the large number of hydrocyclones and low classification efficiency of high-nickel matte classification devices.

Detailed Implementation

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0015] like Figure 1 and Figure 2As shown in the figure, a high-nickel matte pulp hydrocyclone classification device includes: a feed tank 1 with a feeding component arranged at the bottom; a hydrocyclone 2 and a second hydrocyclone 13, which are arranged on one side of the feed tank 1 and are respectively connected to the feed tank 1 through a connecting pipe 12. The bottom outlets of the hydrocyclone 2 and the second hydrocyclone 13 are both connected to a sand receiving tank 7, and the top outlets are respectively connected to an overflow receiving tank 5. The feeding component includes: a pulp feeding pipe 3, the outlet end of which is connected to the bottom of the feed tank 1; a submerged pump 11, which is arranged at the inlet end of the pulp feeding pipe 3. A sand feeding pipe 8 is arranged at the bottom of the sand receiving tank 7; an overflow feeding pipe 6 is arranged at the bottom of the overflow receiving tank 5. The hydrocyclone 2 and the second hydrocyclone 13 are respectively installed on the sand receiving tank 7 through a support frame 9. Both the sand receiving tank 7 and the overflow receiving tank 5 are arranged on a fixed plate 10. The top outlets of the hydrocyclone 2 and the second hydrocyclone 13 are respectively connected to the overflow receiving tank 5 through an overflow pipe 4 and a second overflow pipe 14.

[0016] When the utility model is in use, the bottom of the feed tank 1 is connected to the pulp feeding pipe 3. The high-nickel matte pulp spirally enters the hydrocyclone tank along the tangential direction of the hydrocyclone 2 at a certain pressure and flow rate. The pulp of different particle sizes rotates rapidly along the inner wall of the tank body. Under the action of centrifugal force and gravity, the overflow and sand in the high-nickel matte pulp are separated. The designed processing capacity of the pulp of a single hydrocyclone 2 is 2.0 - 4.5 t / h. An overflow pipe 4 is arranged at the top of each hydrocyclone 2. The inlet of the overflow pipe 4 is connected to the top outlet of the hydrocyclone 2, and the outlets of the overflow pipes 4 are all connected to the overflow receiving tank 5. The overflow after the pulp classification in the hydrocyclone 2 flows into the overflow receiving tank 5 from the outlet of the overflow pipe 4. The bottom outlet of the hydrocyclone 2 is connected to the sand receiving tank 7. The sand after the pulp classification in the hydrocyclone 2 flows into the sand receiving tank 7 from the bottom outlet of the hydrocyclone 2.

[0017] In a specific use example, to further improve the pulp classification efficiency, a submerged pump 11 is arranged on the pulp feeding pipe 3. By increasing the power of the submerged pump 11, the instantaneous pulp flow rate is increased to ensure that the feed tank 1 can supply the pulp flow rate required for the designed processing capacity of two hydrocyclones 2. The pulp flow rate is adjusted according to the production situation, and the pulp flow rate supplied by the submerged pump is controlled at 5.5 - 8.5 t / h.

[0018] In a specific use example, the overflow receiving tank 5 and the sand receiving tank 7 are cubic tank structures. The bottoms of the overflow receiving tank 5 and the sand receiving tank 7 and the feed tank 1 are welded and fixed to the ground by a "J-shaped" fixed plate 10 in the front view schematic diagram, reducing the impact on the feed tank caused by the pulp being supplied from the bottom by the submerged pump 11 through the pulp feeding pipe 3.

[0019] In specific applications, the number of hydrocyclones 2 can be greater than or equal to two. The top view shows the feed tank 1 connected to two hydrocyclones 2. Additional hydrocyclones can be installed on the feed tank 1 according to the actual slurry supply.

[0020] In a specific application example, the overflow receiving pool 5 collects the overflow and discharges it into the overflow feeding pipe 6, with the overflow concentration controlled at 25%-35%.

[0021] In a specific application example, the sedimentation receiving tank 7 collects sediment and discharges it into the sedimentation feeding pipe 8, with the sedimentation concentration controlled at 75%-85%.

[0022] In a specific application example, the sedimentation receiving tank 7 is welded and fixed to the support frame 9 to provide support for the hydrocyclone 2 and better reduce the vibration generated by the hydrocyclone 2 during the slurry classification process.

[0023] The working principle of this invention is consistent with existing high-nickel matte slurry classification devices. Its main feature is that by connecting multiple hydrocyclones to the feed tank, only a single slurry feed pipe is needed to supply slurry to the tank, reducing the number of pipes required for simultaneous operation of multiple hydrocyclones. By increasing the power of the submersible pump, the instantaneous flow rate of the slurry in the feed pipe is increased, and the single feed pipe ensures a stable flow rate. This allows multiple hydrocyclones to operate stably simultaneously, thereby improving the classification efficiency of high-nickel matte slurry. This solves the problems of increased production and management costs due to a large number of hydrocyclones and low efficiency in high-nickel matte classification devices. The device has a small footprint, is simple to set up, and allows for flexible adjustment of the number of hydrocyclones used according to production conditions. If a hydrocyclone malfunctions, it can be easily replaced, serving as a backup for others and facilitating maintenance.
