Description

Technical Field

[0001] This utility model relates to the field of emulsification technology, and in particular to an emulsification device for flotation reagents. Background Technology

[0002] The core function of an emulsifier is to transform immiscible multiphase materials into a uniformly dispersed system through mechanical shearing. This process relies on high-speed shearing force to break up particles, promote phase interface fusion, and remove air bubbles. The stirring components should use high-intensity shearing to subject the material to a continuous process from macroscopic mixing to microscopic dispersion, forming a stable and fine emulsion system.

[0003] However, flotation reagents are complex in composition, often containing high-viscosity organic matter, surfactants, and solid particles. Particle breakage, phase fusion, and bubble removal must be achieved simultaneously during emulsification. Currently, most emulsifiers use a simple agitator. For example, the authorized publication number CN220546889U, entitled "Emulsification Equipment for Coal Mine Flotation Reagents," includes a base and an emulsification tank. An agitator assembly is fixed inside the emulsification tank, and a discharge pipe and a feed pipe are fixed on the tank. The receiving assembly includes a receiving plate. The base is a hollow rectangular plate with an opening on one long side, and a guide groove is provided on the inner side of the base. The receiving plate is located inside the base and can be pulled out of the base, positioned below the discharge pipe and feed pipe after being pulled out.

[0004] In existing technologies, single-structure agitators can only generate unidirectional liquid flow during emulsification, leading to an unbalanced flow field distribution within the equipment: a high-speed shear zone forms in the central region, while the edges and bottom regions are in a low-speed laminar flow state. A large amount of material cannot be effectively sheared, especially high-viscosity components, which are difficult to break down and tend to form an adhesion layer on the wall or localized agglomeration. Simultaneously, the single flow field makes it difficult to remove microbubbles through the alternating action of eddies and laminar flow, resulting in excessive gas content in the reagents. This easily generates interfering foam during flotation, affecting the mineral separation accuracy. Utility Model Content

The central drive component 4 is a motor or other power device, installed on the top of the emulsification tank 2, and provides power to the central stirring member 42. A stirring frame 43 is connected to the bottom of the central stirring member 42. The stirring frame 43 is a U-shaped frame used to stir the side wall of the emulsification tank 2 and prevent the material from sticking to the inner wall of the emulsification tank 2.

[0026] The left stirring assembly 5 and the right stirring assembly 6 are respectively located on both sides of the central stirring assembly 4.

[0031] The flotation reagent emulsification device provided by this utility model includes a support frame 1, an emulsification tank 2 mounted on the support frame 1, and a stirring mechanism 3. The stirring mechanism 3 includes a central stirring component 4, a left stirring component 5, and a right stirring component 6. The central stirring component 4 includes a central drive component 4 and a central stirring member 42, with a stirring frame 43 connected to the bottom of the central stirring member 42. The left stirring component 5 includes a left drive component 54 and a left stirring member, and the right stirring component 6 includes a right drive component 61 and a right stirring member. Through the coordinated operation of the central stirring component 4, the left stirring component 5, and the right stirring component 6, the reagent can be stirred from different positions and directions, expanding the stirring range, reducing dead zones, making the reagent mixing more uniform, and improving the emulsification quality. Furthermore, the different structures of the central stirring member 42, the left stirring member, and the right stirring member allow for different shearing and mixing actions on the reagent, adapting to different types and properties of flotation reagents.

[0032] In this embodiment, preferably, the bottom of the emulsifying tank 2 is provided with a discharge port 22, the top of the emulsifying tank 2 is provided with a feed port 21, and a feed mesh 211 is horizontally arranged on the feed port 21. The feed port 21 is used to transport materials into the interior of the emulsifying tank 2. The feed mesh 211 can filter the materials to prevent impurities from entering the emulsifying tank 2. The discharge port 22 is used to output the emulsified materials. The number of feed ports 21 and discharge ports 22 is set as needed.

[0033] In this embodiment, preferably, there are multiple circular stirring bodies 52, which are arranged at intervals along the axis of the left stirring rod 51. Each circular stirring body 52 includes multiple crushing structures 53 arranged circumferentially. Each crushing structure 53 includes an upper crushing plate 531 arranged inclined upwards and a lower crushing plate 532 arranged inclined downwards. There are multiple upper crushing plates 531, which are arranged at intervals along the circumference of the circular stirring body 52. ​​There are also multiple lower crushing plates 532, which are also arranged at intervals along the circumference of the circular stirring body 52. ​​Thus, the multiple upper crushing plates 531 form an upper crushing layer, and the multiple lower crushing plates 532 form a lower crushing layer. Both the upper crushing plates 531 and the lower crushing plates 532 have pointed tips, which can crush materials. The pointed tips of the upper crushing plates 531 are inclined upwards, and the pointed tips of the lower crushing plates 532 are inclined downwards, thereby achieving crushing of materials from different directions.

[0034] In this embodiment, preferably, the stirring rack 43 includes a first side rod 431, a second side rod 432, and a bottom arc-shaped rod 433 connected to the bottom of the first side rod 431 and the second side rod 432. Thus, the first side rod 431, the bottom arc-shaped rod 433, and the second side rod 432 form a U-shaped frame. There is a certain gap between the first side rod 431, the second side rod 432 and the inner wall of the emulsifying tank 2, and there is also a certain gap between the bottom arc-shaped rod 433 and the bottom of the emulsifying tank 2. The central stirring component 42 includes a central rotating rod, the bottom of which is fixedly connected to the middle position of the bottom arc-shaped rod 433. Thus, when the central rotating rod is driven to rotate, it will cause the first side rod 431, the bottom arc-shaped rod 433, and the second side rod 432 to rotate inside the emulsifying tank 2.

[0035] A side scraper 434 is provided on the side of the first side rod 431 near the inner wall of the emulsifying tank 2. Multiple side scrapers 434 are provided on the first side rod 431, spaced apart sequentially along the length of the first side rod 431. A pre-set gap exists between the side edge of the side scraper 434 and the inner wall of the emulsifying tank 2. When the first side rod 431 rotates, the multiple side scrapers 434 can clean the material adhering to the inner wall of the emulsifying tank 2. The bottom arc-shaped rod 433 includes components connected to the first... The first arc-shaped connecting section is connected to the side rod 431, and the second arc-shaped connecting section is connected to the second side rod 432. The bottom of the first arc-shaped connecting section is provided with a bottom scraper 435. Multiple bottom scrapers 435 are arranged at intervals along the length of the first arc-shaped connecting section. A pre-set gap exists between the bottom scrapers 435 and the bottom of the emulsifying tank 2. The bottom scrapers 435 can stir the material at the bottom of the emulsifying tank 2, thus preventing material accumulation at the bottom of the emulsifying tank 2. Furthermore, the second side rod 432 is not provided with a side scraper 434, and the second arc-shaped connecting section is not provided with a bottom scraper 435. Thus, when the central rotating rod is driven to rotate, the first side rod 431, the bottom arc-shaped rod 433, and the second side rod 432 rotate inside the emulsifying tank 2 to achieve stirring and mixing of the material. The side scrapers 434 prevent material from sticking to the inner wall of the emulsifying tank 2, and the bottom scrapers 435 prevent material from accumulating at the bottom of the emulsifying tank 2.

[0036] In this embodiment, preferably, there are multiple stirring blades 63, which are arranged at intervals along the length of the right stirring rod 62. Each stirring blade 63 includes a connecting post 631 and a first arc-shaped blade 632 and a second arc-shaped blade 633 disposed on the connecting post 631. The connecting post 631 is fixedly installed on the right stirring rod 62. The first arc-shaped blade 632 and the second arc-shaped blade 633 are both inclinedly connected to the connecting post 631, and the inclination directions of the first arc-shaped blade 632 and the second arc-shaped blade 633 are different. By setting the first arc-shaped blade 632 and the second arc-shaped blade 633 in different directions, the material in the emulsification tank 2 can be thoroughly mixed and stirred.

[0037] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
