Description

Technical Field

[0001] This utility model relates to the technical field of flotation mineralizer release heads, specifically a flotation mineralizer release head for ultra-low grade bauxite beneficiation. Background Technology

[0002] A flotation mineralizer is a device used in mineral processing. Its main function is to promote the separation of minerals during flotation. The flotation mineralizer introduces air into the slurry to form bubbles. These bubbles rise in the slurry and combine with hydrophobic mineral particles to form mineralized foam. The release head is mainly used to mix air and slurry to form fine bubbles.

[0003] When performing internal gas injection, vents are usually provided on the surface of the release head to release gas and form bubbles. In this case, if a sealing structure is not provided on the vents, the slurry will be injected when the gas injection stops, which may even cause the vents to become blocked. Furthermore, continuous gas injection will result in uneven bubble sizes. If the bubbles are not split, the flotation rate will be reduced. Utility Model Content

Detailed Implementation

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4 This utility model provides a technical solution: it includes a release head body 4 and a fixing sleeve 1. A hollow drive shaft 2 is rotatably connected inside the fixing sleeve 1. The bottom of the hollow drive shaft 2 extends out of the fixing sleeve 1 and is fixed to the release head body 4. The upper end of the hollow drive shaft 2 extends out of the fixing sleeve 1 and is equipped with an air pipe 7. An air chamber 41 is opened inside the release head body 4. Air holes 42 are evenly arranged on the surface of the air chamber 41. A sealing component 5 is arranged on the surface of the release head body 4 at a position corresponding to the air holes 42. An installation sleeve 3 is fixed on the fixing sleeve 1. A mesh cover 31 is fixed around the installation sleeve 3. The mesh cover 31 is located around the release head body 4. A stirring rod 6 is rotatably connected around the fixing sleeve 1 and above the release head body 4. The air pipe 7 is rotatably connected to the upper end of the hollow drive shaft 2 through a rotating connecting sleeve 71. A drive sprocket 21 is fixed on the hollow drive shaft 2.

[0019] The sealing assembly 5 includes a lifting plate 51 and a sealing plug 52. The lifting plate 51 is installed above the release head body 4 and is aligned with the air hole 42. The sealing plug 52 is fixed to the bottom of the lifting plate 51. A guide rod 53 is fixed at an equidistant position on the release head body 4 and aligned with the periphery of the lifting plate 51. The upper end of the guide rod 53 passes through the lifting plate 51 and is slidably connected to the lifting plate 51. A reset spring 54 is fixed between the bottom of the lifting plate 51 and the upper surface of the release head body 4. A limit plate is fixed to the upper end of the guide rod 53 and the limit plate is located above the lifting plate 51.

[0020] A drive bevel gear 61 is fixed at the bottom of the hollow drive shaft 2 and above the release head body 4. A transmission bevel gear 62 is fixed on the stirring rod 6. The drive bevel gear 61 and the transmission bevel gear 62 mesh. The mesh cover 31 is an upwardly convex arc structure. The stirring rod 6 is located inside the mesh cover 31.

[0021] Working principle: The hollow drive shaft 2 is driven to rotate by the drive structure of the flotation equipment, which in turn drives the release head body 4 to rotate. At this time, gas is injected into the gas chamber 41 through the gas pipe 7, and the gas is discharged from the gas hole 42 to form bubbles. At the same time, when the hollow drive shaft 2 rotates, it drives the drive bevel gear 61 to rotate. Then, through the transmission of the transmission bevel gear 62, it drives the stirring rod 6 to rotate. When the bubbles enter the area of ​​the stirring rod 6, they can be stirred, which can break large bubbles into multiple small bubbles, making the bubbles more uniform. When the bubbles pass through the screen 31, large bubbles will be intercepted and broken, further improving the uniformity of the bubbles and achieving the purpose of improving the flotation rate. Secondly, when the gas is injected, the gas pressure in the gas chamber 41 increases, which will push out the sealing plug 52, thereby causing the lifting plate 51 to move upward and stretch the return spring 54. Conversely, when the gas injection stops, the return spring 54 can be used to pull the lifting plate 51 and the sealing plug 52 back to their original positions, sealing the gas hole 42 and reducing the risk of slurry entering.
