Description

Technical Field

[0001] The utility model relates to a powder granulation device, specifically to a wet powder rolling and ball forming device. Background Art

[0002] A patent with the application number 201811102363.0 discloses an air purification ball, a preparation method thereof and an air purifier. Among them, the air purification ball is prepared by mixing powders such as hydrated lime powder, heavy calcium powder, zeolite powder, tourmaline powder, talc powder, white cement, barite, diatomite, etc., and then made into small balls. The functional materials added to the product can continuously release negative oxygen ions into the air, playing a role in purifying the air. Therefore, the applicant also calls it a negative oxygen ion ball.

[0003] When preparing the above-mentioned negative oxygen ion ball, it is necessary to first mix the powder with water, and then make the wet powder into small balls. The existing technology uses a drum granulator to make balls. The main structure of the drum granulator is a horizontal cylinder. During use, the wet powder is placed in the horizontal cylinder, and the high-speed rotation of the horizontal cylinder is used to make the wet powder tumble in the cylinder, and the balls are formed through extrusion and adhesion. However, the inner wall of the existing horizontal cylinder is cylindrical. During the rotation process, the powders close to the inner wall and far from the inner wall are not evenly stressed, and the tumbling effect is not good, resulting in uneven particle sizes and very irregular shapes when finally rolling into balls.

[0004] In order to solve the above problems, people have been seeking an ideal technical solution. Summary of the Invention

[0005] The purpose of the utility model is to overcome the deficiencies of the prior art, and thus provide a wet powder rolling and ball forming device with scientific design, better tumbling effect, more uniform stress and more regular particles.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is: a wet powder rolling and ball forming device, including a horizontal cylinder and a driving mechanism for driving the horizontal cylinder to roll. The horizontal cylinder is provided with a wavy inner wall, and the wavy inner wall includes wave crest units and wave trough units that are alternately arranged and enclose a circle. The cross-sections of each part of the wave crest units and the cross-sections of each part of the wave trough units are both circular arcs with equal radii.

[0007] Based on the above, the horizontal cylinder includes a cylinder body that runs through along the axial direction, a feed cylinder cover and an air extraction cylinder cover. The feed cylinder cover is installed at one end of the cylinder body, and a feed pipe is provided on the feed cylinder cover. The air extraction cylinder cover is installed at the other end of the cylinder body, and an air extraction pipe is provided on the air extraction cylinder cover.

[0008] Based on the above, a first bearing seat is provided at the center of the feed cylinder cover, and the feed pipe is installed in the first bearing seat through a first bearing.

[0009] Based on the above, a second bearing seat is provided at the center of the air extraction cylinder cover, and the air extraction pipe is installed in the second bearing seat through a second bearing.

[0010] Based on the above, the air inlet of the air extraction pipe extends into the inner side of the air extraction cylinder cover and is arranged upward.

[0011] The utility model has substantial features and progress compared with the prior art. Specifically, by arranging the corrugated inner wall inside the horizontal cylinder body, during the rolling process, it can extrude from different angles, and at the same time, the undulating inner wall can strengthen the tumbling effect of the wet powder, making the force more uniform and the extrusion force greater, which is conducive to forming balls more uniformly and regularly. It has the advantages of scientific design, better tumbling effect, more uniform force, and more regular particles.

[0012] Furthermore, by extracting air through the air extraction pipe, a negative pressure can be generated inside the horizontal cylinder body, and the wet powder in the feed pipe is sucked into the cylinder body, facilitating feeding; the feed pipe is installed through the first bearing, and the air extraction pipe is installed through the second bearing, which can remain stationary when the cylinder body rotates, facilitating connection with external equipment; the air inlet of the air extraction pipe is arranged upward, which can avoid the situation that the powder is sucked into the air extraction pipe.

[0017] The following further describes the technical solutions of the utility model in detail through specific embodiments.

[0018] Such as Figures 1 - 3As shown in the figure, a wet powder rolling and ball forming device includes a horizontal cylinder body and a driving mechanism for driving the horizontal cylinder body to roll. Among them, the driving mechanism can adopt the commonly used drum driving structure in the prior art. For example, it can be a track 2 provided on the outer wall of the cylinder body 1 and a roller 3 cooperating with the track 2.

[0019] In order to make the wet powder form balls more regularly, the horizontal cylinder body is provided with a wavy inner wall 4. The wavy inner wall 4 includes wave crest units 41 and wave trough units 42 that are arranged alternately and enclose a circle. The cross-sections of each part of the wave crest unit 41 and the cross-sections of each part of the wave trough unit 42 are both circular arcs with equal radii.

[0020] During specific use, the uniformly moistened powder material is placed inside the horizontal cylinder body. The driving mechanism drives the horizontal cylinder body to roll. The wavy inner wall can periodically extrude the wet powder from different angles. At the same time, the undulating inner wall can strengthen the tumbling effect of the wet powder, making the force more uniform and the extrusion force greater, which is conducive to forming balls more uniformly and regularly.

[0021] In order to facilitate feeding, the horizontal cylinder body includes a cylinder body 1 that is axially penetrated, a feeding cylinder cover 6, and an air extraction cylinder cover 7. The feeding cylinder cover 6 is installed at one end of the cylinder body 1. A feeding pipe 8 is provided on the feeding cylinder cover 6. The air extraction cylinder cover 7 is installed at the other end of the cylinder body 1. An air extraction pipe 9 is provided on the air extraction cylinder cover 7. When feeding is required, air is extracted through the air extraction pipe 9 to generate negative pressure inside the horizontal cylinder body, and the wet powder in the feeding pipe 8 is sucked into the cylinder body 1.

[0022] To facilitate connecting external feeding equipment and air extraction equipment, a first bearing seat is provided at the center of the feeding cylinder cover 6. The feeding pipe 8 is installed in the first bearing seat through a first bearing 10. A second bearing seat is provided at the center of the air extraction cylinder cover 7. The air extraction pipe 9 is installed in the second bearing seat through a second bearing 11. In this way, it can remain stationary when the cylinder body 1 rotates.

[0023] To prevent the wet powder from being sucked into the air extraction pipe 9, the air inlet 5 of the air extraction pipe 9 extends into the inner side of the air extraction cylinder cover 7 and is arranged upward.

[0024] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them; although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that: it is still possible to modify the specific implementation manners of the present invention or perform equivalent replacements for some technical features; without departing from the spirit of the technical solutions of the present invention, they should all be covered within the scope of the technical solutions claimed by the present invention.
