Description

Technical Field

[0001] The utility model relates to the technical field of feeder design, in particular to a disc feeder, which is mainly used in the field of lithium battery positive electrode material preparation. Background Art

[0002] The positive electrode material of lithium batteries is in powder form. In order to avoid agglomeration, the disc feeder has high requirements for the stirring effect. The existing disc feeder only pushes the material through a scraper, and there is only a conical top cover above the scraper. Although the conical top cover can make the material slide to the periphery, since the feed port is above the rotating shaft, when there is a lot of material, it will still accumulate on the top of the rotating shaft, resulting in a small amount of agglomeration in the discharged material, and the material is prone to sticking to the inner wall of the disc, resulting in material loss.

[0003] Therefore, it is necessary to design a disc feeder with better mixing effect and avoid material loss. Utility Model Content

[0006] Furthermore, the stirring paddle includes a stirring rod connected to the rotating shaft and a scraper located at the end of the stirring rod, the surface of the scraper facing the inner wall of the disk is an arc surface, and the scraper is arranged to fit the inner wall of the disk.

[0007] Furthermore, the side surface of the scraper has an edge facing the rotation direction, and two side surfaces connecting the edge are located at the upper and lower sides of the horizontal plane where the edge is located.

[0008] Furthermore, the side surface of the scraper consists of three planes.

DETAILED DESCRIPTION

[0022] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0023] Embodiment 1

[0024] like Figure 1-Figure 4As shown, a disc feeder comprises a disc 1 and a stirring assembly 2, wherein the stirring assembly 2 comprises a driving motor 201, a rotating shaft 202, a stirring paddle 203 and a scraper 204; the disc 1 comprises a bottom plate 101 and a cylindrical side wall 102, the bottom plate 101 is provided with a discharge port 3, the driving motor 201 is located outside the disc 1 and is installed at the bottom of the bottom plate 101, the rotating shaft 202, the stirring paddle 203 and the scraper 204 are located inside the disc 1, the rotating shaft 202 is located at the center of the disc 1 and is arranged vertically, the lower end of the rotating shaft 202 passes through the bottom plate 101 and is connected to the driving motor 201, and is driven to rotate by the driving motor 201, the upper end of the rotating shaft 202 has a broken arch structure 2021, and the broken arch structure 2021 is a conical structure with a diameter gradually increasing from top to bottom; the stirring paddle 203 and the scraper 204 are connected to the rotating shaft 202. The stirring paddle 203 is arranged close to the arch-breaking structure 2021 , and the scraper 204 is arranged close to the inner bottom surface of the disk 1 .

[0025] The material enters the disc 1 from the top of the rotating shaft 202. First, the arch-breaking structure 2021 diffuses the incoming material to the surroundings. When the material reaches the stirring range of the stirring paddle 203, the material is stirred and rotated. Under the action of centrifugal force, the material will continue to diffuse outward, so that the incoming material gradually diffuses to the periphery, avoiding the subsequent incoming material from accumulating on the top of the rotating shaft 202 and reducing the possibility of material agglomeration. The scraper 204 can further push the material to the discharge port 3. Since the height of the disc feeder is relatively small, the material stirred by the stirring paddle 203 will quickly sink to the scraper 204, so the material stirring effect is good and the work efficiency is high.

[0026] A plurality of stirring paddles 203 and scrapers 204 are provided, and are preferably arranged in a circular array around the rotating shaft 202 .

[0027] The stirring paddle 203 may be a simple straight rod.

[0028] The distance between the scraper 204 and the inner bottom surface of the disc 1 cannot be too far, otherwise it will cause the bottom plate 101 to pile up. As a preferred embodiment, the distance between the lower surface of the scraper 204 and the inner bottom surface of the disc 1 is 1 cm to 2 cm. In a preferred embodiment, the lower surface of the scraper 204 is a plane, and the top of the scraper 204 is an inclined surface 6 extending obliquely downward, which can prevent the top of the scraper 204 from piling up.

[0029] The distance a between the center of the stirring rod 2031 and the lower surface of the conical structure is 5 cm to 8 cm.

[0030] Embodiment 2

[0031] The difference between this embodiment and the first embodiment is that the structure of the stirring paddle 203 is different. Figure 2 and Figure 3As shown, the stirring paddle 203 in this embodiment includes a stirring rod 2031 connected to the rotating shaft 202 and a scraper 2032 located at the end of the stirring rod 2031. The surface of the scraper 2032 facing the inner wall of the disk 1 is an arc surface. The scraper 2032 is arranged to fit the inner wall of the disk 1. The fitting here means that the distance between the scraper 2032 and the cylindrical side wall 102 is very close, but it does not affect the rotation of the rotating shaft 202. The scraper 2032 is mainly used to remove materials adhering to the inner wall of the disk 1.

[0032] In a preferred embodiment, Figure 1 As shown, the side 5 of the scraper 2032 has an edge 4 facing the direction of rotation, and the two side surfaces 5 connecting the edge 4 are located at the upper and lower sides of the horizontal plane where the edge 4 is located. When the rotating shaft 202 rotates, the edge 4 collides with the material head-on, reducing the head-on contact area, and the material is driven to rotate through the upper and lower side surfaces 5, thereby reducing the impact force on the material and preventing the material from being damaged.

[0033] like Figure 1 As shown, the side surface 5 of the scraper 2032 is composed of three planes. In other optional embodiments, the scraper 2032 may also have a curved surface.

[0034] Since the stirring rod 2031 is subjected to relatively large pressure, preferably, an oblique support rod 2033 is connected between the stirring rod 2031 and the rotating shaft 202 , and the oblique support rod 2033 can share the force of the stirring rod 2031 .

[0035] In the description of the present invention, it should be understood that the terms "center", "up", "down", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0036] In addition, in the description of the present invention, unless otherwise specified, “plurality” means two or more.

[0037] In this specification, the schematic representation of the terms does not necessarily refer to the same embodiment. Moreover, the specific features, structures, materials or characteristics described can be combined in any suitable manner in one or more embodiments.

[0038] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without deviating from the technical concept of the utility model through the above description. The technical scope of the utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
