Abstract
Description
Technical Field
[0001] This utility model relates to the field of flotation cell technology, specifically a multi-stage separation flotation cell structure. Background Technology
[0002] A flotation cell is a container used in flotation equipment to perform the flotation process. The main function of a flotation cell is to separate valuable minerals from waste rock in ores using the froth flotation method. Flotation cells are widely used in mineral processing and beneficiation industries, such as copper, lead-zinc, molybdenum, and gold mines.
[0003] Currently, copper mines are characterized by complexity and diversity. When copper mines contain associated metals such as lead, zinc, and molybdenum, they need to be separated one by one through multi-stage flotation to avoid mixing with useful minerals. This necessitates the use of multi-stage separation flotation cell structures to improve concentrate grade and overall recovery rate. However, in multi-stage separation flotation cell structures, aerated screen plates are prone to clogging of bubble pores due to copper ore that has not been completely liberated during the crushing process, high-hardness gangue, or sludge covering the screen plate surface. This clogged bubble pores of the aerated screen plates result in uneven bubble distribution, forming bubble-free zones, which in turn affects copper recovery rate and leads to a decrease in concentrate grade. Therefore, we propose a multi-stage separation flotation cell structure. Utility Model Content
[0004] The purpose of this invention is to provide a multi-stage separation flotation cell structure that has the advantage of preventing the aerated screen plate from clogging the bubble pores. This solves the problem that in multi-stage separation flotation cell structures, the aerated screen plate is easily clogged by copper ore that has not been completely separated in the crushing process, high-hardness gangue, or sludge covering the surface of the screen plate. The clogged aerated screen plate will cause uneven bubble distribution, forming bubble-free zones, which will affect the copper recovery rate and reduce the concentrate grade.

[0008] A negative pressure blower is fixedly installed at the lower end of one side of the roughing separation flotation cell, the cleaning separation flotation cell, and the scavenging separation flotation cell. The output end of the negative pressure blower is connected to the upper end of one side of the bubble screen plate by a duct, and the lower end of the rear side of the bubble screen plate is connected to a vent pipe extending to the bottom of the negative pressure blower.

[0024] Example 1
[0025] Please see Figures 1-4 As shown, this utility model provides a technical solution: a multi-stage separation flotation cell structure, comprising:
[0026] The flotation tank consists of a roughing separation flotation cell 1, a cleaning separation flotation cell 2, a scavenging separation flotation cell 3, and a flotation channel 4. The flotation channel 4 is located at the upper end of the roughing separation flotation cell 1, the cleaning separation flotation cell 2, and the scavenging separation flotation cell 3.
[0027] The bubble screen plate 501 has multiple equally spaced bubble holes 504 on its top. Multiple equally spaced return springs 505 are fixedly connected to the bottom of the inner cavity of the bubble screen plate 501. A movable plug plate 502 that slides inside the bubble screen plate 501 is fixedly connected to the top of the return springs 505. Multiple equally spaced sealing rods 503 are fixedly connected to the top of the movable plug plate 502.
[0028] The negative pressure fan 5 is fixedly installed at the lower end of one side of the roughing separation flotation tank 1, the cleaning separation flotation tank 2, and the scavenging separation flotation tank 3. The output end of the negative pressure fan 5 is connected to the upper end of one side of the bubble screen plate 501 by a guide pipe 506.
[0029] The bubble screen plate 501 is located at the bottom of the inner cavity of the roughing separation flotation tank 1, the cleaning separation flotation tank 2, and the scavenging separation flotation tank 3. The plugging rod 503 is adapted to the bubble hole 504 and is located inside the bubble hole 504. The movable plug plate 502 is located at the middle of the inner cavity of the bubble screen plate 501 and the top of the movable plug plate 502 is located below the air guide pipe 506.
[0030] This technical solution, through the arrangement of a roughing separation flotation tank 1, a cleaning separation flotation tank 2, a scavenging separation flotation tank 3, and a flotation channel 4, allows the ore discharged from the roughing separation flotation tank 1 to be fed into the cleaning separation flotation tank 2 via the flotation channel 4. Then, after flotation again in the cleaning separation flotation tank 2, the ore is fed into the scavenging separation flotation tank 3 via the corresponding flotation channel 4. The ore after further scavenging flows to the next stage of the process via the corresponding flotation channel 4, thus enabling multi-stage separation flotation of copper ore. Through the arrangement of the bubble screen plate 501, during flotation operations in the roughing separation flotation tank 1, the cleaning separation flotation tank 2, and the scavenging separation flotation tank 3, the negative pressure fan 5 can introduce gas into the upper end of the inner cavity of the bubble screen plate 501 via the air guide pipe 506. As the negative pressure at the upper end of the inner cavity of the bubble screen plate 501 increases, it forces the movable plug plate 502 to the bubble screen plate 501. The inner cavity moves downwards, and the movement of the movable plug plate 502 compresses the return spring 505. At the same time, the gas at the lower end of the inner cavity of the bubble screen plate 501 can be discharged outwards through the vent pipe 507. When the movable plug plate 502 moves downwards, it will drive the sealing rod 503 to exit the bubble hole 504. Then, as the negative pressure fan 5 continues to input gas, the gas can be discharged outwards through the bubble hole 504, ensuring the normal operation of flotation. After the flotation is completed, the negative pressure fan 5 stops working, and as the negative pressure at the upper end of the inner cavity of the bubble screen plate 501 decreases, the compressed return spring 505 can drive the movable plug plate 502 to reset. The reset movable plug plate 502 will drive the sealing rod 503 to re-insert into the bubble hole 504. At this time, the reset sealing rod 503 will protrude from the top of the bubble screen plate 501, thus preventing the bubble screen plate 501 from becoming blocked and ensuring the normal operation of the bubble screen plate 501.
[0031] It should be noted that the flotation channel 4 on the roughing separation flotation cell 1 is connected to one side of the cleaning separation flotation cell 2, while the flotation channel 4 of the cleaning separation flotation cell 2 is connected to one side of the scavenging separation flotation cell 3, thereby realizing the flow during multi-stage mineral flotation. In addition, the roughing separation flotation cell 1, the cleaning separation flotation cell 2, and the scavenging separation flotation cell 3 are all equipped with real-time water replenishment pipes to ensure the liquid level in the roughing separation flotation cell 1, the cleaning separation flotation cell 2, and the scavenging separation flotation cell 3. The liquid level is monitored in real time by a level gauge, and it is not just the flow between flotation minerals. Since this is a mature and conventional method in the existing technology, it will not be described in detail here.
[0032] Example 2
[0033] Based on Embodiment 1, this utility model is as follows: Figures 1-4 As shown, a guide pipe 401 is connected to the right side of the flotation channel 4.
[0034] This technical solution: By setting up the guide pipe 401, the minerals after multi-stage separation flotation can be diverted and brought into the process.
[0035] It should be noted that the negative pressure fan 5, the roughing separation flotation cell 1, the cleaning separation flotation cell 2, and the scavenging separation flotation cell 3 used in this structure can all be purchased directly from the market. At the same time, the connection methods and electrical connections of each component adopt mature conventional methods in the existing technology, so they will not be described in detail here.
[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
