Description

Technical Field

[0001] This utility model generally relates to the field of lithium battery technology. More specifically, this utility model relates to a stirring disperser. Background Technology

[0002] In industries such as lithium batteries, chemicals, food, and coatings, toothed dispersion discs are generally used in the batching process of high-viscosity slurries. Chinese utility model patent application number "202120589839.9" discloses a rotationally stable stirring structure, which employs a single-layer dispersion disc on a rotating shaft. This dispersion disc has at least two layers of agitating tooth units distributed circumferentially and extending into the shaft. This type of agitator / disperser has the following drawbacks during stirring: First, because the dispersion disc has at least two layers of agitating tooth units distributed circumferentially and extending into the shaft, the linear velocity of the teeth near the center is lower than that of the teeth further away from the center during rotation, resulting in weaker dispersion force in the central area. Second, the dispersion teeth extend radially to the center, and the distance between the two layers of teeth is relatively close, making it difficult to clean the slurry residue between the two layers after stirring. These defects in existing dispersers significantly affect the stirring and dispersion effect, failing to fully achieve the purpose of effective and rapid stirring, mixing, emulsifying, and shearing of high-viscosity slurries.

[0003] In view of this, there is an urgent need to provide a stirring disperser to solve the problem. Utility Model Content

[0004] To at least solve one or more of the technical problems mentioned in the background section, this invention proposes a stirring and dispersing device.

[0005] Therefore, the present invention provides the following technical solution.

[0006] This utility model discloses a stirring and dispersing device, including: a wheel rim and two annular toothed discs. The two annular toothed discs are detachably arranged along the axial direction of the wheel rim and are respectively located on the first end face and the second end face of the wheel rim in the axial direction. The center line of the wheel rim in the axial direction passes through the geometric center of the two annular toothed discs, and the orthographic projections of the two annular toothed discs in the axial direction of the wheel rim coincide.

[0007] Preferably, the wheel rim includes an inner ring body and an outer ring body fixedly connected by multiple spokes, the geometric centers of the inner ring body and the outer ring body coincide, and two annular toothed discs are respectively fixed to the first end face and the second end face in the axial direction of the outer ring body.

[0008] Preferably, the included angle between any two adjacent spokes is equal.

[0009] Preferably, the cross-section of each spoke is an irregular polygon.

[0010] Preferably, the outer circumferential surface of the outer ring body in the radial direction is provided with a plurality of flow guide holes.

[0011] Preferably, at least two positioning grooves are provided on both the first end face and the second end face, and the annular toothed disk has a number of protrusions equal to the number of positioning grooves on either end face, so that when either annular toothed disk is fixed on the first end face or the second end face, each protrusion on the annular toothed disk is located in the corresponding positioning groove.

[0012] Preferably, the annular gear disc is bolted to the wheel rim.

[0013] Preferably, the annular toothed disk includes a ring and a plurality of toothed plates arranged alternately in a vertical fashion on the outer edge of the ring.

[0014] Preferably, the outer radius of the ring is greater than the outer radius of the outer ring body, and when the annular toothed disc is fixed to the first end face or the second end face of the outer ring body, the toothed disc does not interfere with the outer ring body.

[0015] The technical solution provided in this application may include the following beneficial effects:

[0016] By utilizing the device described above and in several embodiments of this invention, namely, by detachably arranging two annular toothed discs on two end faces in the axial direction of the wheel rim, and ensuring that the orthographic projections of the two annular toothed discs in the axial direction of the wheel rim coincide, the linear velocities of the teeth at all points on the two annular toothed discs are equal during stirring, thereby ensuring that the dispersion force at all points on the annular toothed discs used for stirring is the same, which helps to improve the stirring effect; in addition, since the annular toothed discs located on the two end faces of the wheel rim are detachably arranged, the residue between the two annular toothed discs is easy to clean.

[0021] Embodiments will now be described with reference to the accompanying drawings. It should be understood that, for the sake of simplicity and clarity, reference numerals may be repeated in the drawings to indicate corresponding or similar elements where deemed appropriate. Furthermore, numerous specific details are set forth in this invention to provide a thorough understanding of the embodiments described herein. However, those skilled in the art will understand that the embodiments described herein can be practiced without these specific details. In other instances, well-known methods, processes, and components have not been described in detail so as not to obscure the embodiments described herein. Moreover, this description should not be construed as limiting the scope of the embodiments described herein.

[0022] According to one embodiment of the present invention, a stirring disperser is provided, such as... Figure 1 and Figure 2 As shown, it includes: a wheel rim 11 and two annular toothed discs 12. The two annular toothed discs 12 are detachably disposed along the axial direction of the wheel rim 11 and are respectively located on the first end face and the second end face of the wheel rim 11 in the axial direction. The center line of the wheel rim 11 in the axial direction passes through the geometric center of the two annular toothed discs 12, and the orthographic projections of the two annular toothed discs 12 in the axial direction of the wheel rim 11 coincide.

[0023] In one embodiment, the rim 11 includes an inner ring body 22 and an outer ring body 23 fixedly connected by a plurality of spokes 21, the geometric centers of the inner ring body 22 and the outer ring body 23 coincide, and two annular toothed discs 12 are respectively fixed to the first end face and the second end face in the axial direction of the outer ring body 23.

[0024] In the above embodiments, the included angle between any two adjacent spokes 21 is equal. Specifically, the number of spokes 21 can be three, in which case the included angle between adjacent spokes 21 is 120 degrees; or the number of spokes 21 can be four, in which case the included angle between adjacent spokes 21 is 90 degrees.

[0025] In one embodiment, the cross-section of each spoke 21 is an irregular polygon. During mixing, the flowability of the stirred material and the shear force on the material are improved by the guiding effect of the irregular outer surface of the spoke 21, thereby enhancing the mixing effect.

[0026] In the above embodiment, the outer circumferential surface of the outer ring body 23 in the radial direction is provided with a plurality of guide holes 41. The guide holes 41 can be set to avoid the position of the spokes 21, and can be set off at an offset, which does not affect the firm connection between the inner ring body 22 and the outer ring body 23, and can provide fluidity to the stirred slurry through the multiple guide holes 41.

[0027] The annular gear disk 12 and the rim 11 are fixed in the following way. Specifically, since the rim 11 includes an inner ring body 22 and an outer ring body 23, and the outer ring body 23 has a first end face and a second end face in the axial direction, at least two positioning grooves 51 can be provided on each of the first and second end faces. Each annular gear disk 12 has a number of protrusions 52 equal to the number of positioning grooves 51 on any end face, so that when any annular gear disk 12 is fixed to the first or second end face, each protrusion 52 on the annular gear disk 12 is located in the corresponding positioning groove 51. The relative rotation between the rim 11 and the annular gear disk 12 is limited by the above method. Simultaneously, the annular gear disk 12 and the rim 11 are connected by bolts. For example, through holes are provided on the annular gear disk 12, and bolt holes are provided on both end faces of the rim 11, thereby connecting the two with bolts to limit the axial displacement of the rim 11 and the annular gear disk 12, and thus fixing them. The advantage of bolt connection is that it also facilitates disassembly and cleaning.

[0028] In one embodiment, the annular toothed disk 12 includes a ring 71 and a plurality of toothed plates 72 arranged alternately in vertical positions along the outer edge of the ring 71. The annular toothed disk 12 can be formed by sequentially cutting multiple equidistant notches along the edge of a ring 71 and sequentially bending adjacent toothed plates 72 vertically.

[0029] In the above embodiment, the outer radius of the ring 71 is larger than the outer radius of the outer ring body 23. When the annular toothed disc 12 is fixed to the first or second end face of the outer ring body 23, the toothed disc 72 does not interfere with the outer ring body 23. Specifically, the edges of the two end faces of the outer ring body 23 can be extended radially away from the guide hole 41. At the same time, when bending the toothed disc 72 up and down, the edges of each toothed disc 72 are oriented away from the axial center line of the wheel rim 11 to avoid interference between the toothed disc 72 and the outer ring body 23.
