Description

Technical Field

[0001] The utility model relates to the technical field of powder production and processing equipment, in particular to a powder surface coating treatment device. Background Art

[0002] At present, ultrafine powders usually refer to particles with a particle size of micrometers or nanometers. Compared with large pieces of conventional materials, they have larger specific surface area, surface activity and higher surface energy, and thus exhibit excellent optical, thermal, electrical, magnetic, catalytic and other properties. Ultrafine powders as a functional material have been widely studied in recent years and have been increasingly widely used in various fields of national economic development.

[0003] There are various existing methods for coating powders, including microemulsion coating, which uses tiny water cores provided by microemulsion to prepare ultrafine powders to be coated, and then coats and modifies the powders through microemulsion polymerization. However, some manufacturers mix the emulsion with the powder and then stir it, but the effect is not ideal, because a large amount of emulsion and powder are contacted and stirred at one time, some powders will be coated more by the emulsion and some will be coated less, and normal stirring will cause some powders to be pushed to the edge of the stirring rod and difficult to fully mix with the emulsion. Therefore, it is necessary to design an organic emulsion coating powder processing device that can allow the powder to be fully coated with the emulsion. Utility Model Content

[0004] In order to solve the technical problem that simple mixing and stirring cannot make all powders uniformly coated with emulsion, the utility model provides a powder surface coating treatment device.

[0005] The utility model is implemented by the following technical scheme: a powder surface coating treatment device, comprising a preparation barrel, a cover plate is provided on one side of the preparation barrel, a spraying assembly for spraying organic emulsion on the powder inside the preparation barrel is provided on one side of the preparation barrel, a stirring assembly for stirring and mixing the powder and the organic emulsion is provided inside the preparation barrel, a plurality of spray holes are opened on one side of the preparation barrel, the spray assembly comprises a spray pipe arranged on one side of the preparation barrel and a plurality of spray heads fixedly installed on the spray pipe, and one end of each of the spray heads extends to the inside of an adjacent spray hole.

[0006] Through the above technical solution, when coating the powder, the organic emulsion is sprayed onto the powder in the form of a spray, and combined with a full range of stirring components, the powder can be effectively and evenly coated.

[0007] As a further improvement of the above scheme, a lotion box is provided on one side of the preparation barrel, a water pump is provided on one side of the lotion box, the water inlet end of the water pump is fixedly connected to a liquid inlet pipe fixedly connected to the lotion box, and the water outlet end of the water pump is fixedly connected to an infusion pipe fixedly connected to the spraying pipe.

[0008] Through the above technical solution, the emulsion for coating the powder will be evenly sprayed onto the powder in the form of a spray.

[0009] As a further improvement of the above solution, the stirring assembly includes a rotating rod disposed inside the preparation cylinder and a plurality of stirring rods fixedly mounted on the rotating rod. Each of the stirring rods is arranged in a "C" shape, and one end of the rotating rod is sleeved with a rotating sleeve fixedly mounted on the inner wall of the preparation cylinder.

[0010] Through the above technical solution, when the rotating rod rotates, the stirring rods will stir the powder and the emulsion.

[0011] As a further improvement of the above solution, a fixing sleeve is fixedly sleeved on each of the stirring rods, and a plurality of cutting rods are fixedly mounted on one side of each of the fixing sleeves. Each of the cutting rods is arranged in a rhombus shape.

[0012] Through the above technical solution, the agglomerated powder being stirred will be separated by the cutting rods, preventing the powder from piling up and being inconvenient to stir.

[0013] As a further improvement of the above solution, a scraper is fixedly mounted on one side of each of the fixing sleeves. One side of each of the scrapers is in contact with the inner wall of the preparation cylinder, and a plurality of through holes are formed in each of the scrapers.

[0014] Through the above technical solution, the scraper will completely push all the powder for stirring, and the powder will also disperse through the through holes.

[0015] As a further improvement of the above solution, a servo motor is provided on one side of the preparation cylinder. One end of the rotating rod penetrates through the cover plate and is fixedly mounted on the output end of the servo motor. A support plate fixedly mounted on the cover plate is fixedly mounted on one side of the servo motor.

[0016] Through the above technical solution, when the servo motor is started, the rotating rod will rotate, thereby fully stirring the emulsion and the powder.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0018] By providing a spraying assembly and a stirring assembly, when coating the powder with the emulsion, the spraying assembly will evenly spray the emulsion onto the powder, and then the stirring assembly will fully stir the mixture of the powder and the emulsion, enabling the emulsion to evenly coat the powder. Such a setting can not only allow the emulsion to evenly cover the surface of the powder, but also enable the powder and the emulsion to be evenly mixed, avoiding the situation in normal and simple stirring where some powder is pushed to the edge of the stirring position, resulting in uneven stirring of the powder.

[0024] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0025] Please combine Figure 1-Figure 3 A powder surface coating treatment device of the present embodiment comprises a preparation barrel 1, a cover plate is provided on one side of the preparation barrel 1, a spraying assembly for spraying an organic emulsion on the powder inside the preparation barrel 1 is provided on one side of the preparation barrel 1, a stirring assembly for stirring and mixing the powder and the organic emulsion is provided inside the preparation barrel 1, a plurality of spray holes are opened on one side of the preparation barrel 1, the spraying assembly comprises a spraying pipe 201 arranged on one side of the preparation barrel 1 and a plurality of spraying heads 202 fixedly mounted on the spraying pipe 201, one end of each spraying head 202 extends to the inside of an adjacent spraying hole, an emulsion tank 4 is provided on one side of the preparation barrel 1, a water pump 5 is provided on one side of the emulsion tank 4, a water inlet end of the water pump 5 is fixedly connected to a liquid inlet pipe 6 fixedly connected to the emulsion tank 4, and a water outlet end of the water pump 5 is fixedly connected to a liquid infusion pipe 7 fixedly connected to the spraying pipe 201. When coating the powder, the organic emulsion is sprayed onto the powder in the form of a spray, and in conjunction with the all-round stirring assembly, the powder can be effectively and evenly coated.

[0026] Combination Figure 1-Figure 3, the stirring assembly includes a rotating rod 301 disposed inside the preparation cylinder 1 and a plurality of stirring rods 302 fixedly mounted on the rotating rod 301. Each stirring rod 302 is arranged in a "C" shape. One end of the rotating rod 301 is sleeved with a rotating sleeve fixedly mounted on the inner wall of the preparation cylinder 1. A fixing sleeve 8 is fixedly sleeved on each stirring rod 302. A plurality of cutting rods 9 are fixedly mounted on one side of each fixing sleeve 8. Each cutting rod 9 is arranged in a rhombus shape. A scraper 10 is fixedly mounted on one side of each fixing sleeve 8. One side of each scraper 10 is in contact with the inner wall of the preparation cylinder 1. A plurality of scattering holes penetrating through itself are formed on each scraper 10. A servo motor 11 is provided on one side of the preparation cylinder 1. One end of the rotating rod 301 penetrates through the cover plate and is fixedly mounted on the output end of the servo motor 11. A support plate fixedly mounted on the cover plate is fixedly mounted on one side of the servo motor 11. When the servo motor 11 is started, the rotating rod 301 will rotate. The scraper 10 will push all the powder completely for stirring, and the powder will also pass through the scattering holes and disperse, so as to fully stir the emulsion and the powder.

[0027] The implementation principle of a powder surface coating treatment device in the embodiment of the present application is as follows: Open the cover plate and put the powder into the preparation cylinder 1. Start the servo motor 11 to drive the rotating rod 301 to drive the stirring rod 302 to rotate, so that the powder inside the preparation cylinder 1 will disperse. Then start the water pump 5 to spray the emulsion in the emulsion tank 4 into the preparation cylinder 1 in the form of mist through the spraying pipe 201 and the spraying head 202. In this way, the powder being stirred will uniformly contact the misty emulsion, and the scraper 10 will shovel up all the powder for stirring to avoid the situation that there is residual powder at the bottom of the preparation cylinder 1 that cannot be stirred. When the powder is piled up, it will be separated by the cutting rod 9 during the stirring process to avoid being piled up together and not being fully stirred. When the uniform stirring is completed, the emulsion will also uniformly coat the powder. Open the cover plate to take it out. Such a setting can not only make the emulsion evenly cover the surface of the powder, but also make the powder and the emulsion be uniformly mixed, avoiding the situation that in normal and simple stirring, part of the powder will be pushed to the edge of the stirring position, resulting in uneven stirring of the powder.

[0028] The above implementation manners are only the preferred implementation manners of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention belong to the protection scope required by the present invention.
