Description

Technical Field

[0001] This utility model relates to the field of mineral flotation technology, specifically to a mineral microbubble flotation filtration device. Background Technology

[0002] Flotation is a mineral processing method that separates minerals by utilizing the differences in the physicochemical properties of their surfaces. The most widely used method in industry is froth flotation, which is characterized by the selective attachment of useful minerals to air bubbles in the slurry, which then float to the surface of the slurry, thus achieving the separation of useful minerals from gangue.

[0003] Existing flotation filtration equipment typically consists of a rectangular tank. The slurry is fed into the tank, and the equipment agitates and injects gas, causing the slurry to react and generate numerous bubbles that float to the top. These bubbles are then scraped away by a scraper. While this method effectively achieves flotation and filtration of the slurry, it has significant drawbacks in practical application, such as:

[0004] When the scraper removes foam, it is electrically driven to rotate at the top of the pool. The foam can only be scraped away when the scraper rotates to the bottom. However, this means that the scraper can only scrape the foam in the same position each time. When the foam at the back stops moving forward, the scraper will stop running and cannot continue to scrape the foam, resulting in reduced scraping efficiency.

[0005] Therefore, a mineral microbubble flotation filtration device that can improve the efficiency of foam removal is now being designed to address these shortcomings. Utility Model Content

[0006] To address the shortcomings of existing technologies, this invention provides a mineral microbubble flotation filtration device, which solves the problem of low skimming efficiency in existing mineral flotation devices.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a mineral microbubble flotation filtration device, comprising a flotation cylinder and a grouting bend, wherein the grouting bend is disposed at the top of the flotation cylinder, and an annular steam frame is fixedly connected to the bottom of the inner cavity of the flotation cylinder by a bracket, an aerator is fixedly connected to the left side of the surface of the flotation cylinder by a bracket, and both the air inlet and outlet of the aerator are connected to air supply pipes, one end of the air supply pipe on the right side penetrates the flotation cylinder and communicates with the annular steam frame, and a defoaming cylinder is fixedly connected to the bottom of the inner cavity of the flotation cylinder by opening an opening.

[0008] Preferably, a conical baffle is fixedly connected to the bottom of the flotation cylinder by a bracket, a motor is fixedly connected to the inner side of the conical baffle by a bracket, and the output shaft of the motor is fixedly connected to a first rotating rod by a coupling, and the top end of the first rotating rod passes through the defoaming cylinder and extends to the top of the flotation cylinder.

[0009] Preferably, one end of the first rotating rod extending to the upper part of the flotation cylinder is fixedly connected to a shaped top plate via a fixing block. The bottom of the shaped top plate is rotatably connected to a second rotating rod via a bearing component, and several second rotating rods are provided. The second rotating rods are located between the flotation cylinder and the defoaming cylinder.

[0010] Preferably, a stirring blade is fixedly connected to the bottom end of the first rotating rod, a gear is fixedly connected to the upper part of the surface of the second rotating rod, and a toothed ring that cooperates with the gear is fixedly connected to the upper part of the flotation cylinder through a bracket.

[0011] Preferably, the surface of the second rotating rod is rotatably connected to an inclined scraper via a bearing, and the inclined scraper is located at the top of the foam discharge cylinder. A guide ring is fixedly connected between the bottoms of several inclined scrapers via a fixing block, and the guide ring is rotatably mounted on the surface of the foam discharge cylinder.

[0012] This invention provides a microbubble flotation filtration device for minerals. Compared with existing technologies, it has the following advantages:

[0013] (1) The mineral microbubble flotation filter device has a grouting bend installed at the bottom of the flotation cylinder cavity and several second rotating rods installed on the top of the flotation cylinder using a special-shaped top plate. At the same time, the surface of the second rotating rods is provided with inclined scrapers, which are used in conjunction with guide rings. When the motor drives the second rotating rods to rotate using the special-shaped top plate, the several inclined scrapers rotate around the top of the grouting bend, thereby continuously pushing the foam at the top towards the middle until the foam is discharged from the top of the grouting bend. There is no need to wait for the foam to move forward, which effectively improves the foam removal efficiency.

[0014] (2) The mineral microbubble flotation filter device is used by installing gears on the surface of the second rotating rod, in combination with toothed rings and stirring blades. The configuration of these structures allows the second rotating rod to drive the inclined scraper to revolve, while the stirring blades also rotate, stirring and mixing the bottom of the slurry and the reagent solution, thereby improving the reaction rate and meeting the current requirements.

An aerator 4 is fixedly connected to the left side of the surface of the flotation cylinder 1 through a bracket. The air inlet and outlet of the aerator 4 are both connected to air supply pipes 5. One end of the right air supply pipe 5 passes through the flotation cylinder 1 and is connected to the annular steam frame 3. A defoaming cylinder 6 is fixedly connected to the bottom of the inner cavity of the flotation cylinder 1 through an opening.

[0023] Furthermore, a conical baffle 7 is fixedly connected to the bottom of the flotation cylinder 1 via a bracket, and a motor 8 is fixedly connected to the inner side of the conical baffle 7 via a bracket.

[0024] The first rotating rod 9 extends to one end of the flotation cylinder 1 and is fixedly connected to a special-shaped top plate 10 by a fixing block. The bottom of the special-shaped top plate 10 is rotatably connected to a second rotating rod 11 by a bearing component. Several second rotating rods 11 are provided. The second rotating rods 11 are located between the flotation cylinder 1 and the defoaming cylinder 6.

[0025] The bottom end of the first rotating rod 9 is fixedly connected to a stirring blade 12, the upper part of the surface of the second rotating rod 11 is fixedly connected to a gear 15, the upper part of the flotation cylinder 1 is fixedly connected to a toothed ring 16 that cooperates with the gear 15 through a bracket, the surface of the second rotating rod 11 is rotatably connected to an inclined scraper 13 through a bearing, and the inclined scraper 13 is located at the top of the foam discharge cylinder 6.

[0026] In use, the slurry and reagents are injected into the flotation cylinder 1 through the injection bend 2.
