Description

Technical Field

[0001] This invention relates to the field of stirring and mixing, and more specifically, to a raw material mixing apparatus for the production and processing of fluorides. Background Technology

[0002] Fluorides are widely used in modern industry, and the mixing of raw materials is one of the key steps in their production process. In traditional raw material mixing devices, a large amount of foam is often generated on the liquid surface during the mixing process due to factors such as the properties of the raw materials, stirring speed, and reaction conditions.

[0003] In existing technologies, physical methods are typically used to address foam generated during mixing. However, some existing mixing devices fail to adequately consider actual operating conditions such as liquid surface fluctuations and material viscosity when dealing with surface foam, resulting in unstable foam elimination effects and difficulty in achieving continuous and efficient foam treatment. Therefore, we propose a raw material mixing device for fluoride production and processing. Summary of the Invention

[0032] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0033] like Figures 1-9 As shown, a raw material mixing device for fluoride production and processing includes: a raw material reaction vessel 11, and a mixing and stirring mechanism 2 disposed inside the raw material reaction vessel 11;

[0034] The mixing and stirring mechanism 2 includes a stirring main shaft 22, a floating cylinder 24 that is slidably fitted outside the stirring main shaft 22, two liquid-spraying arms 25 that are symmetrically fixed on both sides of the floating cylinder 24, and a foam elimination component. The tops of the two liquid-spraying arms 25 are in contact with the inner wall of the raw material reaction vessel 11.

[0035] The liquid-scraping arm 25 has an open structure on the side facing the rotation direction of the stirring shaft 22, and a shovel arm 28 that can move with the liquid surface is movably installed inside it. The cross-section of the shovel arm 28 is streamlined.

[0036] The foam elimination assembly includes a foam-pulling rope 46 that rotates behind the shovel arm 28 and a miniature air pump 51 located inside the float 24;

[0037] As the surface-sweeping arm 25 rotates with the stirring shaft 22, the shovel arm 28, with its streamlined structure, scoops up the surface material, allowing foam to enter the interior of the surface-sweeping arm 25 and gather around the foam-pulling rope 46. The foam is then continuously transported to the flotation cylinder 24 via the foam-pulling rope 46. The micro air pump 51 draws in gas above the liquid surface of the raw material reaction vessel 11 and forms a high-pressure airflow that blows onto the foam, thus eliminating the bubbles.

[0038] The top of the stirring shaft 22 extends through the center of the tank cover of the raw material reactor 11, and the top is fixedly connected to the tank cover of the raw material reactor 11. Multiple sets of stirring blades 23 are fixedly installed on the outer wall of the stirring shaft 22 below the floating cylinder 24.

[0039] An extension cylinder 27 is fixedly installed on the upper wall of the floating cylinder 24, and the extension cylinder 27 is also sleeved on the outside of the stirring main shaft 22. Both the extension cylinder 27 and the floating cylinder 24 are slidably connected to the stirring main shaft 22. Several drag-reducing beads 48 are arrayed on the inner wall of the extension cylinder 27, and the drag-reducing beads 48 are rotatably connected to the extension cylinder 27. The several drag-reducing beads 48 are in contact with the outer wall of the stirring main shaft 22.

[0040] A buoyancy air box 52 is fixedly installed on the inner bottom wall of the buoyancy cylinder 24, and the buoyancy air box 52 has a completely sealed structure. The micro air pump 51 is fixed above the buoyancy air box 52. Several air inlets 26 are fixedly embedded on the top of the extension cylinder 27. The several air inlets 26 are all connected to the air inlet end of the micro air pump 51 through the air intake pipe 49.

[0041] The air outlet of the micro air pump 51 is connected to the air pipe 36 and the foam spray pipe 53 respectively. The air outlet of the foam spray pipe 53 is directly facing one end of the air inlet float cylinder 24 of the foam rope 46. The end of the air pipe 36 away from the micro air pump 51 is connected to the shovel arm 28.

[0042] The thickness of the shovel arm 28 at the open position near the liquid-spreading arm 25 is smaller than the thickness of the shovel arm 28 away from the open position. Floating plates 34 are fixedly installed on the upper walls of both ends of the shovel arm 28, and elastic films 37 are fixedly installed inside the floating plates 34.

[0043] A guide post 39 is inserted through the center of the elastic film 37. The outer wall of the guide post 39 and the elastic film 37 form a fixed sealing structure. The top of the guide post 39 is fixedly connected to the inner upper wall of the liquid-spreading arm 25. Pull-up elastic ropes 38 are arranged on the outer wall of the guide post 39 below the elastic film 37, and several pull-up elastic ropes 38 are fixed to the inner wall of the floating plate 34.

[0044] The inside of the shovel arm 28 is fixedly provided with a main diversion pipe 43, and one end of the main diversion pipe 43 is connected to the vent pipe 36. Several jet branch pipes 41 are fixedly provided on one side of the main diversion pipe 43. A foaming groove 35 is opened on the upper rear wall of the shovel arm 28. Several jet heads 42 are fixedly arrayed on the inner wall of the foaming groove 35, and the several jet heads 42 correspond one-to-one with the several jet branch pipes 41.

[0045] A foam-removing film 47 is fixedly arrayed on the foam-removing rope 46. A second transmission reel 45 is provided at one end of the foam-removing rope 46 inside the buoy 24, and the second transmission reel 45 is rotatably connected to the buoy 24.

[0046] The end of the foaming rope 46 away from the second transmission reel 45 is provided with a first transmission reel 44, and the first transmission reel 44 is rotatably connected to the liquid-spraying arm 25. A turntable 29 is fixedly provided below the first transmission reel 44, and the side wall of the turntable 29 penetrates the top of the liquid-spraying arm 25 and contacts the inner wall of the raw material reaction vessel 11.

[0047] In use, the raw materials required for fluoride production are added to the raw material reaction vessel 11. The stirring motor body 21 drives the stirring main shaft 22 to rotate, and the stirring main shaft 22 drives multiple sets of stirring blades 23 to stir the liquid raw materials.

[0048] The buoyancy air box 52 inside the float cylinder 24 and the material itself are buoyant, which allows the float cylinder 24 to float on the surface of the liquid. As the stirring shaft 22 rotates, the drag-reducing beads 48 contact the stirring shaft 22 and the rotation of the liquid surface can slowly make the float cylinder 24 rotate, so that the two liquid-sweeping arms 25 rotate slowly on the liquid surface along with the float cylinder 24.

[0049] When the two liquid-spreading arms 25 rotate, the liquid-shoveling arm 28 will scoop up the upper surface of the liquid and pass over the upper surface of the shoveling arm 28, entering through the opening of the liquid-spreading arm 25. A mesh 31 is fixedly installed on the rear wall of the liquid-spreading arm 25, and a counterweight column 32 is fixedly installed below the mesh 31. The side wall of the mesh 31 is fixedly connected to the liquid-spreading arm 25 through the limiting pull wire 33. At this time, the liquid entering the liquid-spreading arm 25 will pass through the mesh 31, while the foam will be blocked by the mesh 31 at the position of the foam pulling rope 46. The mesh 31 can swing freely with the change of the liquid level.

[0050] The float 24 floats on the liquid surface, and the extension tube 27 is much higher than the liquid surface. At this time, the micro air pump 51 works, and the air above the liquid surface is drawn into the micro air pump 51 through the air inlet 26. Part of it is sprayed onto the foam rope 46 through the foam spray pipe 53, and the other part enters the main diversion pipe 43 through the air pipe 36.

[0051] The gas entering the main diversion pipe 43 is then ejected through multiple jet branch pipes 41 and jet head 42. The gas flows in a semi-circular manner along the foaming groove 35 and then flows vertically upward. The small amount of liquid remaining in the foaming groove 35 is blown by the high-pressure gas to form small water droplets, which impact the foam, break the bubbles in the foam, and forcibly block the liquid and foam flowing along the surface of the shovel arm 28 to prevent them from flowing back into the liquid.

[0052] The turntable 29 contacts the inner wall of the raw material reactor 11. As it rotates, the turntable 29 rotates, which in turn drives the first transmission plate 44 to rotate, thereby causing the foam-pulling rope 46 to rotate between the first transmission plate 44 and the second transmission plate 45. The foam-pulling film 47 can carry a large amount of foam into the flotation cylinder 24, and the high-pressure gas sprayed through the foam spraying pipe 53 can eliminate the foam in the flotation cylinder 24.

[0053] The shovel arm 28 is hollow. As the liquid is stirred, the liquid surface fluctuates, and the shovel arm 28 drives the floating plate 34 to float up and down. Meanwhile, the guide column 39 is tightened from multiple directions by multiple tension ropes 38, which ensures both the floating and stability of the shovel arm 28.

[0054] Mixing and stirring mechanism 2: The stirring main shaft 22 drives the stirring blade group 23 to carry out the main mixing. At the same time, the floating cylinder 24 and the liquid surface brush arm 25 work together to effectively deal with the liquid surface foam, improve the mixing uniformity and efficiency, and reduce the interference of foam on the reaction process.

[0055] The floating cylinder 24 is slidably mounted on the stirring shaft 22: using the buoyancy air box 52 and buoyancy material, the floating cylinder 24 can float with the liquid surface, adapt to changes in liquid level, and ensure that the liquid surface brushing arm 25 is always in contact with the liquid surface, thereby improving the stability of foam collection.

[0056] The shovel arm 28 has a streamlined cross-section: reducing liquid flow resistance, smoothly shoveling up the surface material and foam, guiding it into the interior of the surface-sweeping arm 25, and improving foam collection efficiency.

[0057] Foam elimination component: Foam rope 46 carries foam through foam film 47, and micro air pump 51 generates high-pressure airflow to blow away the foam, achieving continuous foam elimination and preventing foam accumulation from affecting the reaction.

[0058] Air inlet 26 and suction pipe 49: Miniature air pump 51 draws in gas above the liquid surface to form a high-pressure airflow, which is used to eliminate foam, prevent the introduction of external gas, and maintain a stable reaction environment.

[0059] Vent pipe 36 and spray pipe 53: High-pressure airflow is split, spray pipe 53 directly acts on the foam on the foam rope 46, vent pipe 36 delivers gas to the shovel arm 28, and breaks the foam through the jet head 42 to achieve multi-point elimination.

[0060] The shovel arm features a 28mm thickness design, with a thinner front end and a thicker rear end: the thinner front end facilitates shoveling, while the thicker rear end provides structural strength, ensuring durability during long-term use.

[0061] Floating plate 34 and elastic film 37: allow the shovel arm 28 to float up and down with the fluctuation of the liquid surface, maintain contact with the liquid surface, and improve adaptability and foam collection effect.

[0062] Guide column 39 and tension rope 38: tighten the shovel arm 28 from multiple directions to ensure stability during floating and prevent excessive swinging or deviation.

[0063] The main diversion pipe 43, the jet branch pipe 41, and the jet head 42: uniformly distribute high-pressure gas, form an airflow through the foaming groove 35, break the foam and block the liquid backflow, and enhance the foam elimination efficiency.

[0064] Foaming rope 46 and conveyor reel: enable continuous rotation of foaming rope 46 and automatically convey foam to the flotation cylinder 24 for centralized processing.

[0065] Turntable 29 contacts the inner wall of raw material reactor 11: the rotational friction drives the first transmission disc 44, so that the foam rope 46 runs automatically, reducing the additional power requirement.

[0066] The embodiments of the present invention have been described above. However, the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms based on the guidance of the present embodiments, all of which are within the protection scope of the present embodiments.
