Description

Technical Field

[0001] The utility model relates to the technical field of jet emulsification, in particular to a flotation agent jet emulsification device. Background Art

[0002] Flotation agents are chemicals used in the mineral flotation process to adjust the surface properties of minerals, increase or decrease their floatability, and make the pulp properties and foam stability more conducive to mineral separation. Jet emulsification of flotation agents refers to the process of passing flotation agents (such as collectors and frothers) through a jet emulsifier, causing the agent molecules to form a stable, uniform emulsion in water.

[0003] When using existing jet emulsification devices, an appropriate amount of water is added to the emulsification tank. The collector and foaming agent are then ejected into the emulsification tank at high speed through the jet portion. The jet of collector and foaming agent generates shear and impact forces, thereby better dispersing the collector and foaming agent into the water and achieving emulsification. However, in existing jet emulsification devices, the collector and foaming agent are injected directly into the emulsification tank without prior premixing, which affects the jet emulsification effect. A higher jet velocity is required to achieve the desired emulsification level, resulting in limited effectiveness. Utility Model Content

[0004] The main purpose of the utility model is to provide a flotation agent jet emulsification device, which can effectively solve the problems in the background technology.

An electric valve and a premixing bucket are provided on the feed pipe, and a top cover is provided at the upper end of the premixing bucket.

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0018] like Figure 1-Figure 4 As shown, a flotation agent jet emulsification device includes a jet drive tube 1, to which a drive motor 2 is connected, and an ejector 3 is connected. The ejector 3 is provided with a feed pipe 4, and the end of the ejector 3 is connected to an emulsification tank 11. The feed pipe 4 is provided with an electric valve 5 and a premixing bucket 6, and the upper end of the premixing bucket 6 is provided with a top cover 7, which is provided with a micro reduction motor 8. The interior of the premixing bucket 6 is provided with a stirring structure 9. The lower ends of the jet drive tube 1, the drive motor 2, and the ejector 3 are provided with a base 14. The upper end of the stirring structure 9 is connected to the micro reduction motor 8. A feeding pipe 10 is fixed to the top cover 7. One end of the emulsification tank 11 is provided with an inlet pipe 12, and the other end of the emulsification tank 11 is fixed with a discharge pipe 13. By providing the premixing bucket 6, top cover 7, micro reduction motor 8 and stirring structure 9, the collector and foaming agent can be premixed to ensure the subsequent jet emulsification effect. The required emulsification degree can be achieved at a lower jet speed, reducing the difficulty of emulsification.

[0019] When using a jet emulsification device to perform jet emulsification of flotation reagents, the device is stably placed on the base 14. Collectors and frothers are added to the pre-mixing hopper 6 through the feeding pipe 10. An appropriate amount of water is added to the emulsification tank 11 through the feeding pipe 12. The micro-reduction motor 8 on the top cover 7 is started. Driven by the micro-reduction motor 8, the stirring mechanism 9 operates to pre-mix the collector and frother. After mixing is completed, the electric valve 5 is opened, the micro-reduction motor 8 is reversed, and the stirring mechanism 9 reverses to convey the mixed material into the ejector 3. At the same time, the drive motor 2 is started, and the airflow generated inside the jet drive pipe 1 carries the mixed material to the emulsification tank 11 at high speed, thereby achieving the purpose of emulsification. After emulsification is completed, the material can be discharged through the discharge pipe 13.

[0020] Through the above implementation scheme, the stirring structure 9 includes a rotating shaft 901, a spiral stirring blade 902, a transverse stirring blade 903, a connecting rod 904 and a scraper assembly 905. The upper end of the rotating shaft 901 is connected to the micro-reduction motor 8, the spiral stirring blade 902 is fixed to the lower end of the rotating shaft 901, the transverse stirring blade 903 is installed at the middle position of the rotating shaft 901, the connecting rod 904 is connected to the scraper assembly 905, and the connecting rod 904 is installed on the transverse stirring blade 903. The transverse stirring blade 903, the connecting rod 904, and the scraper assembly 905 are distributed in a circular array on the rotating shaft 901.

[0021] The scraper assembly 905 includes a vertical scraper plate 9051, a movable rod 9052, a baffle 9053, a spring 9054 and an inclined scraper plate 9055. The vertical scraper plate 9051 is fixedly connected to the movable rod 9052, and the movable rod 9052 passes through the connecting rod 904. The baffle 9053 is fixed to the end of the movable rod 9052. The spring 9054 is sleeved on the movable rod 9052, and the spring 9054 is located between the connecting rod 904 and the baffle 9053. The inclined scraper plate 9055 is connected to the lower end of the vertical scraper plate 9051.

[0022] When pre-mixing the collector and the foaming agent, after starting the micro-reduction motor 8, the rotating shaft 901 rotates with the spiral stirring blades 902 and the horizontal stirring blades 903 to mix the collector and the foaming agent. During this process, due to the action of centrifugal force, the vertical scraper plate 9051 and the inclined scraper plate 9055 move outward through the movable rod 9052 to contact the inner wall of the pre-mixing bucket 6, and the baffle 9053 compresses the spring 9054. During the mixing process, the scraper plate scrapes the inner wall of the pre-mixing bucket 6 to ensure the uniformity of material mixing. When the materials are mixed, the micro-reduction motor 8 rotates in the opposite direction, the stirring structure 9 rotates in the opposite direction, and the spiral stirring blades 902 convey the mixture to ensure rapid discharge. At the same time, under the action of the scraper assembly 905, the inner wall of the pre-mixing bucket 6 will not adhere to the material, ensuring the completeness of the discharge. When the stirring structure 9 stops rotating, under the action of the spring 9054, the baffle 9053 moves and resets with the movable rod 9052, the vertical scraper plate 9051, and the inclined scraper plate 9055, which is convenient for subsequent cleaning work. It has a simple structure and excellent use effect.

[0023] It should be noted that the spiral stirring blades 902 and the horizontal stirring blades 903 are provided in the stirring structure 9, which can increase the premixing effect and improve the mixing uniformity. A scraper assembly 905 is provided on the connecting rod 904. Under the action of centrifugal force, the vertical scraper plate 9051 and the inclined scraper plate 9055 are close to the inner wall of the premixing bucket 6, which can effectively play a scraping role and prevent material from remaining on the inner wall of the premixing bucket 6. At the same time, a spring 9054 is provided on the movable rod 9052. The spring 9054 is used in conjunction with the centrifugal force to ensure that the vertical scraper plate 9051 and the inclined scraper plate 9055 can fit the inner wall of the premixing bucket 6 to ensure the scraping effect. When the stirring structure 9 is not rotating, it can be recycled and made way for easy cleaning.
