Description

Technical Field

[0001] The utility model relates to the technical field of mixing equipment, in particular to a raw material mixer for preparing a rare earth collector. Background Art

[0002] Rare earth collector is a chemical agent specially used for the flotation of rare earth minerals. It can change the hydrophobicity of the mineral surface and make the floating mineral particles adhere to the bubbles, thereby achieving the separation and purification of the minerals. This collector is usually a special flotation agent formulated based on specific organic compounds. Its main components include a variety of highly efficient polar groups and hydrophobic groups. These groups can effectively adsorb and encapsulate specific rare earth minerals, thereby achieving effective collection of rare earth minerals.

[0003] When mixing various raw materials of the collector, a mixing device is used to fully mix the collector raw materials with a good ratio. Since the raw material components contained in different types of collectors are also different, some components in some collector formulas may have strong adhesion or electrostatic properties and are easily attached to the inner wall of the equipment. In addition, uneven stirring or improper stirring speed during the mixing process may also cause the material to be deposited on the inner wall, and the collector remaining on the inner wall of the mixing equipment cannot be effectively recycled. At the same time, it also brings inconvenience to the subsequent cleaning process. Therefore, the Chinese patent application disclosed by the existing publication number CN219072686U is not suitable for the recycling of collectors. Utility model patent: A fertilizer mixing device that is easy to clean. This application prevents fertilizer from adhering to the inner wall by setting a rotating cleaning scraper on the inner wall of the fertilizer mixing box. This type of cleaning scraper can be used to scrape and clean the residue on the inner wall of the mixing device. However, since the output shaft drives the cleaning scraper to rotate continuously through the driving turntable and the annular disk, and one side of the cleaning scraper will continue to rotate along the inner wall of the mixing device, after a certain period of use, one side of the cleaning scraper will cause material wear due to continuous friction, so that one side of the cleaning scraper cannot be in contact with the inner wall of the mixing device, which will affect the scraping of residual materials.

[0026] like Figure 2-Figure 5As shown, a sealing tube 19 is provided in the base 5, and two rotating grooves 29 are provided inside the sealing tube 19. A plurality of connecting rods 20 are fixedly connected between the outer side of the sealing tube 19 and the base 5, one end of one of the connecting rods 20 passes through the base 5 and extends to the outside of the base 5 and is provided with a second air hole 21, and one end of the connecting rod 20 provided with the second air hole 21 is connected to an external air compression device through a pipeline, a plurality of first air holes 17 are provided inside the rotating shaft 7, and sealing rings 18 are fixedly installed on the outer side of the rotating shaft 7 located above and below the first air holes 17, and the rotating shaft 7 is inserted in the sealing tube 19, and the outer side of the sealing ring 18 is rotatably installed on In the corresponding rotating groove 29, a first compression spring 24 is installed at the bottom of the rotating shaft 7, and a plurality of first air holes 17 are opened in the rotating shaft 7. In conjunction with the setting of the sealing tube 19 and the connecting rod 20, pressurized gas can be injected into the rotating shaft 7 in conjunction with external air compression equipment. A plurality of sealing rings 22 are installed at the outside of the pressure rod 14, and a plurality of embedding grooves 23 are opened at the outside of the pressure rod 14. The lower end of the pressure rod 14 abuts against the upper end of the first compression spring 24. By injecting high-pressure gas into the inner cavity of the rotating shaft 7 located above the pressure rod 14, the pressure rod 14 can be moved downward in the rotating shaft 7, thereby being able to synchronously squeeze and displace a plurality of telescopic rods 16.

[0027] like Figure 2 , Figure 5-Figure 6 As shown, the third stirring rod 11 and the fourth stirring rod 12 are both hollow structures, and the inner cavity of the third stirring rod 11 is connected to the inner cavity of the rotating shaft 7. A contact rod 26 is fixedly installed at one end of the telescopic rod 16 relative to the pressure rod 14, and one end of the contact rod 26 passes through the limit ring 25 and extends into the rotating shaft 7.

The pressure rod 14 cooperates with the embedding groove 23 to realize the synchronous movement of multiple groups of telescopic rods 16 and contact rods 26, so that when cleaning the inner wall of the stirring tank 1, the scraper 15 can be used to abut against the inner wall of the stirring tank 1 to scrape and clean the residue on the inner wall of the stirring tank 1.

[0028] It should be noted that the utility model is a raw material mixer for preparing a rare earth collector. After the materials are mixed by the rotating shaft 7 and the second stirring rod 9, the first stirring blade 10, the third stirring rod 11, and the third stirring rod 11, the fourth stirring rod 12, and the second stirring blade 13, after unloading, part of the materials will remain on the inner wall of the stirring tank 1. At this time, the air compression and pipeline can be controlled by an external main controller to inject high-pressure gas into one of the connecting rods 20, so that the high-pressure gas enters the rotating shaft 7 through the multiple first air holes 17 opened on the inner side of the rotating shaft 7, thereby pressing the pressure rod 14 on the rotating shaft 7. The contact rod 26 is pressed downwardly in the inner part, thereby causing the multiple embedded grooves 23 on the outer side of the pressure rod 14 to move downward at one end of the corresponding contact rod 26, and causing the embedded grooves 23 to disengage from one end of the contact rod 26, so that the pressure rod 14 squeezes the contact rod 26 to move to one side, so that the contact rod 26 drives the telescopic rod 16 to move in the corresponding third stirring rod 11. At the same time, the contact rod 26 also compresses the second compression spring 28 toward the side of the limit ring 25 in the third stirring rod 11 through the fixing ring 27. As a result, the multiple telescopic rods 16 synchronously drive the scraper 15 to move horizontally in the stirring tank 1, so that one side of the scraper 15 contacts the stirring tank 1 The inner wall of the mixing tank 1 is made of a rubber material, and one side of the scraper 15 can be closely attached to the inner wall of the mixing tank 1 by using the scraper 15. Thus, the motor 6 can continue to drive the rotating shaft 7 to rotate, and the rotating shaft 7 can drive the telescopic rod 16 to rotate through the third stirring rod 11 and the fourth stirring rod 12, and then the telescopic rod 16 drives the scraper 15 to rotate, so that one side of the scraper 15 rotates along the inner wall of the mixing tank 1, and the material remaining on the inner wall of the mixing tank 1 can be scraped off. When the material remaining on the inner wall of the mixing tank 1 is scraped off, the air compression device is turned off and the pressure is released through the external controller, so that the pressure above the pressure rod 14 is The inner cavity of the rotating shaft 7 no longer has pressurized gas, and the pressure rod 14 is pushed up by the force of the first compression spring 24 stretching and rebounding, so that the pressure rod 14 moves up in the rotating shaft 7 and makes the embedding groove 23 outside the pressure rod 14 move to the corresponding side of the contact rod 26. At this time, the second compression spring 28 outside the contact rod 26 stretches and rebounds and supports the fixing ring 27 to move to one side, so that one end of the contact rod 26 is in contact with a certain embedding groove 23, and the contact rod 26 simultaneously drives the telescopic rod 16 to reset and move in the third stirring rod 11, so that the telescopic rod 16 drives the scraper 15 to separate from the inner wall of the stirring tank 1.
