Description

Technical Field

[0001] This invention relates to the field of micro-nano technology, and more specifically to a circulating emulsifying pump for preparing conductive slurries. Background Technology

[0002] Conductive slurries are typically prepared using micro-nano dispersion systems, where the emulsifying pump is a precision combination of rotor and stator that generates strong shear force during high-speed rotation to achieve mixing, homogenization, dispersion, and pulverization.

[0003] To achieve emulsification of different particle sizes, existing emulsification pumps require the replacement of rotor discs with different numbers of teeth. However, this operation is time-consuming and labor-intensive, and the long downtime also greatly affects work efficiency.

[0004] Therefore, it is necessary to provide a new type of circulating emulsifying pump for preparing conductive slurries. Summary of the Invention

[0005] Based on the aforementioned problems in the existing technology, the purpose of this invention is to provide a circulating emulsifying pump for preparing conductive slurry, which can be easily adjusted to meet different emulsification particle size requirements and effectively improve work efficiency.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A circulating emulsifying pump for preparing conductive slurry is provided, comprising a casing, a stator toothed disk, and a rotor toothed disk. The stator toothed disk is housed within the inner cavity of the casing and is fixedly connected to the casing. The rotor toothed disk is housed within the inner cavity of the casing and is rotatable relative to the casing. The stator toothed disk and the rotor toothed disk are arranged opposite each other in the axial direction of the casing. The stator toothed disk includes a stator disk connected to the casing and a plurality of stator teeth. The plurality of stator teeth are circumferentially spaced on the end face of the stator disk near the rotor toothed disk, with a stator tooth gap between adjacent stator teeth. The rotor toothed disk includes a rotor disk and a plurality of rotor teeth. The plurality of rotor teeth are circumferentially spaced on the end face of the rotor disk near the stator toothed disk. The rotor teeth include a first tooth and a second tooth. The first and second rotor teeth slide and engage with the rotor disk circumferentially. A rotor tooth gap is formed between adjacent first and second rotor teeth in the circumferential direction of the rotor disk. A drive roller is installed between each first and second rotor tooth, and the drive roller rotates and engages with the rotor disk. The drive roller is linked with the first and second rotor teeth. A central wheel is coaxially mounted on the rotor disk and rotates with the rotor disk. The central wheel is connected to the drive roller so that the central wheel can drive the drive roller to rotate. The rotation of the drive roller drives the first and second rotor teeth to slide. When the first and second rotor teeth slide and move away from each other, the rotor tooth gap between adjacent first and second rotor teeth in the circumferential direction of the rotor disk decreases. When the first and second rotor teeth slide and move closer together, the rotor tooth gap between adjacent first and second rotor teeth in the circumferential direction of the rotor disk increases.

[0007] Furthermore, the extension path of the rotor tooth gap is inclined radially relative to the rotor disk.

[0008] Furthermore, the first and second gear teeth are L-shaped. The end faces of the rotor disk and stator disk opposite each other are provided with sliding grooves. The sliding grooves extend circumferentially along the rotor disk. The first gear tooth includes a sliding block and an action block 1 inclinedly disposed at the end of the sliding block 1 opposite to the second gear tooth. At least the sliding block 1 of the first gear tooth is slidably installed in the sliding groove. The side of the action block 1 opposite to the second gear tooth is provided with a baffle wall 1. The extension path of the baffle wall 1 is inclined relative to the radial direction of the rotor disk. The second gear tooth includes a sliding block 2 and an action block 2 inclinedly disposed at the end of the sliding block 2 opposite to the first gear tooth. At least the sliding block 2 of the second gear tooth is slidably installed in the sliding groove. The side of the action block 2 opposite to the first gear tooth is provided with a baffle wall 2. The extension path of the baffle wall 2 is inclined relative to the radial direction of the rotor disk. The first and second gear teeth are arranged in a 180-degree circular array around the axis of the drive roller. The adjacent baffle walls 1 and 2, as well as the two end faces of the rotor disk and stator disk opposite to each other, form the rotor tooth gap.

[0009] Furthermore, the transmission roller is sandwiched between sliding block one and sliding block two. Sliding block one has a toothed part one on the side near the transmission roller, and sliding block two has a toothed part two on the side near the transmission roller. The toothed part one meshes with the transmission roller, and the toothed part two meshes with the transmission roller.

[0010] Furthermore, the transmission roller is connected to the central wheel via a transmission structure, the transmission structure including a first gear mounted on the transmission roller, the first gear meshing with the central wheel.

[0011] Furthermore, the circulating emulsifying pump for preparing conductive slurry also includes a conversion mechanism and a piston cylinder. The piston cylinder is slidably fitted onto the tube shell along the axial direction of the tube shell, and the conversion mechanism is connected between the piston cylinder and the central wheel.

[0012] Furthermore, a hydraulic chamber is provided between the piston cylinder and the shell, and a hydraulic flow channel communicating with the hydraulic chamber is provided on the outer wall of the shell. An elastic element is also installed between the piston cylinder and the shell, and the elastic element applies an elastic thrust to the piston cylinder to drive the piston cylinder to slide close to the rotor toothed disc.

[0013] Furthermore, the conversion mechanism includes a sliding sleeve, a rotating sleeve, a connecting frame, and an elastic element two. The sliding sleeve is coaxially arranged with the rotor disk and slides along the axial direction of the rotor disk. The rotating sleeve is coaxially arranged with the central wheel and connected to the central wheel. The rotating sleeve is located at the end of the central wheel near the piston cylinder and is sleeved on the sliding sleeve. The connecting frame is fixedly connected to the piston cylinder and rotatably connected to the sliding sleeve. The elastic element two is installed between the rotor disk and the sliding sleeve. The elastic element two applies an elastic thrust to the sliding sleeve to drive the sliding sleeve to slide away from the rotor disk. A conversion groove is provided on the peripheral side wall of the sliding sleeve. The conversion groove has a spiral structure around the axis of the sliding sleeve. A guide pin block is installed on the side wall of the rotating sleeve. The guide pin block extends to the inside of the rotating sleeve and is received and installed in the conversion groove.

[0014] Furthermore, the sliding sleeve is provided with a plug at one end near the rotor disk, and the rotor disk is provided with a plug hole extending axially, and the plug is inserted and slidably installed in the plug hole.

[0015] Furthermore, the circulating emulsifying pump for preparing conductive slurry also includes a drive shaft, which at least partially extends into the inner cavity of the casing, and the rotor disk is fixedly connected to the drive shaft.

[0016] Compared with the prior art, one or more technical solutions in the embodiments of the present invention have at least one of the following beneficial effects: The circulating emulsifying pump for preparing conductive slurry in this embodiment of the invention includes a casing, a stator toothed disk, and a rotor toothed disk. The inner cavity of the casing is provided for material passage. The stator toothed disk is housed within the inner cavity of the casing and is fixedly connected to the casing. The rotor toothed disk is also housed within the inner cavity of the casing and is rotatable relative to the casing. The stator toothed disk and the rotor toothed disk are arranged opposite each other in the axial direction of the casing. The stator toothed disk includes a stator disk connected to the casing and a plurality of stator teeth, which are circumferentially spaced on the end face of the stator disk near the rotor toothed disk. The rotor tooth disk includes a rotor disk and multiple rotor teeth. These rotor teeth are spaced apart along the circumference of the rotor disk on the end face of the rotor disk near the stator tooth disk. Each rotor tooth includes a first tooth and a second tooth. The first and second teeth slide on the rotor disk along its circumference. A rotor tooth gap is formed between adjacent first and second teeth along the circumference of the rotor disk. A drive roller is installed between the first and second teeth of each rotor tooth. The drive roller rotates in conjunction with the rotor disc, and is linked to tooth segments one and two. A central wheel, coaxially mounted on the rotor disc, rotates in conjunction with the rotor disc. The central wheel is connected to the drive roller, so that its rotation drives the drive roller to rotate. The rotation of the drive roller drives tooth segments one and two of the rotor teeth to slide. When tooth segments one and two slide and move away from each other, the rotor tooth gap between adjacent tooth segments one and two in the circumferential direction of the rotor disc decreases. Conversely, when tooth segments one and two slide and move closer together, the gap between adjacent tooth segments one and two in the circumferential direction of the rotor disc decreases. The increased rotor tooth gap between tooth one and tooth two, compared to the existing design that requires replacing the rotor tooth disc, allows the circulating emulsifying pump for preparing conductive slurry provided in this embodiment of the invention to freely adjust the size of the rotor tooth gap. When the rotor tooth gap is reduced, the shearing, friction, and turbulence effects on the material are increased; when the rotor tooth gap is increased, the shearing, friction, and turbulence effects on the material are reduced. Compared to the existing technology, there is no need to replace the rotor tooth disc, making it easier to adjust the equipment to meet different emulsification particle size requirements and effectively improving the working efficiency of the equipment.

[0037] Please refer to Figures 1 to 13As shown, a circulating emulsifying pump for preparing conductive slurry provided by the present invention will now be described. This circulating emulsifying pump for preparing conductive slurry includes a casing 1, a stator toothed disc 3, and a rotor toothed disc 4. The inner cavity of the casing 1 is provided for material passage. The stator toothed disc 3 is housed within the inner cavity of the casing 1 and is fixedly connected to the casing 1. The rotor toothed disc 4 is housed within the inner cavity of the casing 1 and is rotatable relative to the casing 1. The stator toothed disc 3 and the rotor toothed disc 4 are located within the casing 1. The stator gear disk 3 is arranged axially opposite to the rotor gear disk 4. The stator gear disk 3 includes a stator disk 31 connected to the housing 1, and multiple stator teeth 32. The multiple stator teeth 32 are spaced circumferentially along the end face of the stator disk 31 near the rotor gear disk 4. A stator tooth gap 33 separates adjacent stator teeth 32. The rotor gear disk 4 includes a rotor disk 41 and multiple rotor teeth 5. The multiple rotor teeth 5 are spaced circumferentially along the end face of the rotor disk 41 near the stator gear disk 3. Figure 7 As shown, the rotor tooth 5 includes a first tooth 51 and a second tooth 52. The first tooth 51 and the second tooth 52 are slidably fitted onto the rotor disk 41 along its circumference. A rotor tooth gap 53 is formed between adjacent first teeth 51 and second teeth 52 in the circumferential direction of the rotor disk 41. That is, a rotor tooth gap 53 is formed between adjacent rotor teeth 5 in the circumferential direction of the rotor disk 41. A transmission roller 42 is installed between the first tooth 51 and the second tooth 52 of each rotor tooth 5. The transmission roller 42 is rotatably fitted with the rotor disk 41 and is linked with the first tooth 51 and the second tooth 52. A central wheel 44 is coaxially arranged on the rotor disk 41 and is rotatably fitted with the rotor disk 41. The central wheel 44 is connected to the transmission roller 42 so that the central wheel 44 can drive the transmission roller 42 to rotate when it rotates. The rotation of the transmission roller 42 will drive the first tooth 51 and the second tooth 52 of the rotor tooth 5 to slide and intersect the first tooth 51 and the second tooth 52 of the rotor tooth 5. When the first tooth 51 and the second tooth 52 slide and move away from each other, the rotor tooth gap 53 between adjacent first tooth 51 and second tooth 52 in the circumferential direction of rotor disk 41 decreases. When the first tooth 51 and the second tooth 52 of rotor tooth 5 slide and move closer together, the rotor tooth gap 53 between adjacent first tooth 51 and second tooth 52 in the circumferential direction of rotor disk 41 increases. Therefore, compared with the prior art design of replacing rotor tooth disk 4, the circulating emulsifying pump for preparing conductive slurry provided by the present invention can freely adjust the size of rotor tooth gap 53. When the rotor tooth gap 53 is reduced, the shearing, friction and turbulence of the material is improved, and when the rotor tooth gap 53 is increased, the shearing, friction and turbulence of the material is reduced. Compared with the prior art, there is no need to replace rotor tooth disk 4, and it is more convenient to adjust the equipment to meet different emulsification particle size requirements, effectively improving the working efficiency of the equipment.

[0038] like Figure 1As shown, in some embodiments, the front end of the tube shell 1 is provided with an inlet end for material to enter, and the rear end of the tube shell 1 is provided with an outlet end for material to exit. The rotation of the rotor toothed disk 4 can drive the material in the inner cavity of the tube shell 1 to move from the inlet end to the outlet end.

[0039] like Figure 12 and Figure 13 As shown, in some embodiments, the extension path of the rotor tooth gap 53 is inclined relative to the radial direction of the rotor disk 41. Thus, when the rotor disk 4 rotates at high speed, the object located in the rotor tooth gap 53 will be thrown towards the outer edge of the rotor disk 4, i.e. the peripheral wall of the tube shell 1, under the action of centrifugal force. At the same time, the center of the rotor disk 4 generates negative pressure due to the reduction of the object, attracting the object to move closer to the rotor disk 4. Thus, the high-speed rotation of the rotor disk 4 forms a pump suction, causing the material in the inner cavity of the tube shell 1 to move from the inlet end to the outlet end. At the same time, the material flows through the stator tooth gap 33 and the rotor tooth gap 53, completing the comprehensive action of shearing, squeezing, and friction on the material to achieve emulsification.

[0040] like Figure 7 , Figure 12 and Figure 13 As shown, in some embodiments, the first tooth 51 and the second tooth 52 have an L-shaped structure. The end faces of the rotor disk 41 opposite to the stator tooth disk 3 are provided with sliding grooves 411, which extend circumferentially along the rotor disk 41. The first tooth 51 includes a sliding block 511 and an action block 512 inclined at one end of the sliding block 511 away from the second tooth 52. At least the sliding block 511 in the first tooth 51 is slidably installed in the sliding groove 411. A baffle 514 is provided on the side of the action block 512 away from the second tooth 52, and the extension path of the baffle 514 is inclined relative to the radial direction of the rotor disk 41. The second tooth 52 includes a sliding block 521 and an action block 521 inclined at one end of the sliding block 521 away from the first tooth 51. 522, at least the sliding block 521 in the second tooth 52 is slidably installed in the sliding groove 411. The side of the second tooth 522 facing away from the first tooth 51 is provided with a second baffle 524. The extension path of the second baffle 524 is inclined relative to the radial direction of the rotor disk 41. The first tooth 51 and the second tooth 52 are arranged in a 180-degree circular array around the axis of the transmission roller 42. The adjacent first baffle 514, the second baffle 524, and the two opposite end faces of the rotor disk 41 and the stator disk 31 surround and form the rotor tooth gap 53. When the first tooth 51 and the second tooth 52 slide along the circumference of the rotor disk 41 at the same time, the adjacent first baffle 514 and the second baffle 524 move closer and further away, thereby causing the rotor tooth gap 53 to decrease and increase accordingly.

[0041] like Figure 12 and Figure 13As shown, in some embodiments, the drive roller 42 is sandwiched between sliding block 1 511 and sliding block 2 521. Sliding block 1 511 has a tooth 1 513 on the side near the drive roller 42, and sliding block 2 521 has a tooth 2 523 on the side near the drive roller 42. The tooth 1 513 meshes with the drive roller 42, and the tooth 2 523 meshes with the drive roller 42, so that the drive tooth 1 51 and the tooth 2 52 will slide circumferentially along the rotor disk 41 by the circumferential rotation of the drive roller 42.

[0042] like Figure 12 and Figure 13 As shown, in some embodiments, the transmission roller 42 is connected to the central wheel 44 via a transmission structure 43. In this embodiment, the transmission structure 43 is a gear structure. The transmission structure 43 transmits torsional force between the transmission roller 42 and the central wheel 44 through inter-tooth meshing. More specifically, the transmission structure 43 includes a first gear mounted on the transmission roller 42, which meshes with the central wheel 44. In this embodiment, the rotor disk 41 is provided with multiple rings of rotor teeth 5. The transmission structure 43 also includes a second gear rotatably engaged on the rotor disk 41. The second gear is positioned between two adjacent first gears in the radial direction of the rotor disk 41 to achieve the same rotational direction of the two adjacent first gears in the radial direction of the rotor disk 41. Thus, when the central wheel 44 rotates, the multiple first gears will maintain rotation in the same direction, achieving uniform adjustment of the rotor tooth gap 53.

[0043] like Figure 2 As shown, in some embodiments, the circulating emulsifying pump for preparing conductive slurry further includes a switching mechanism 6 and a piston cylinder 7. The piston cylinder 7 is slidably fitted onto the casing 1 along the axial direction of the casing 1. The switching mechanism 6 is connected between the piston cylinder 7 and the central wheel 44. When the piston cylinder 7 slides along a first direction, the switching mechanism 6 drives the central wheel 44 to rotate along a first rotational direction. And when the piston cylinder 7 slides along a second direction opposite to the first direction, the switching mechanism 6 drives the central wheel 44 to rotate along a second rotational direction opposite to the first rotational direction. Figure 12 and Figure 13 As shown, by controlling the rotation of the central wheel 44 along the first or second rotation direction, the first tooth 51 and the second tooth 52 of the rotor tooth 5 slide in opposite directions or in opposite directions.

[0044] like Figure 2As shown, in some embodiments, a hydraulic chamber 8 is provided between the piston cylinder 7 and the shell 1. A hydraulic flow channel 11 communicating with the hydraulic chamber 8 is provided on the outer wall of the shell 1. An elastic element 71 is also installed between the piston cylinder 7 and the shell 1. The elastic element 71 applies an elastic thrust to the piston cylinder 7 to drive the piston cylinder 7 to slide closer to the rotor toothed disk 4. By introducing or discharging high-pressure medium into the hydraulic flow channel 11, the pressure of the hydraulic chamber 8 is changed. When the pressure of the hydraulic chamber 8 increases, it generates a pushing motion on the piston cylinder 7, pushing the piston cylinder 7 to slide in a direction away from the rotor toothed disk 4. Or when the pressure of the hydraulic chamber 8 decreases, the piston cylinder 7 is pushed by the elastic force of the elastic element 71 to slide in a direction closer to the rotor toothed disk 4.

[0045] like Figure 2 , Figure 9 and Figure 10 As shown, in some embodiments, the conversion mechanism 6 includes a sliding sleeve 61, a rotating sleeve 62, a connecting frame 63, and an elastic element 64. The sliding sleeve 61 is coaxially arranged with the rotor disk 41 and slides along the axial direction of the rotor disk 41. The rotating sleeve 62 is coaxially arranged with the central wheel 44 and connected to the central wheel 44. The rotating sleeve 62 is located at the end of the central wheel 44 near the piston cylinder 7 and is sleeved on the sliding sleeve 61. The connecting frame 63 is fixedly connected to the piston cylinder 7 and rotatably connected to the sliding sleeve 61. The elastic element 64 is installed between the rotor disk 41 and the sliding sleeve 61. The elastic element 64 applies an elastic thrust to the sliding sleeve 61, causing the sliding sleeve 61 to slide away from the rotor disk 41. Figure 11 As shown, the sliding sleeve 61 has a conversion groove 611 on its peripheral sidewall. The conversion groove 611 has a spiral structure around the axis of the sliding sleeve 61. A guide pin block 46 is installed on the sidewall of the rotating sleeve 62. The guide pin block 46 extends to the inside of the rotating sleeve 62 and is housed in the conversion groove 611. When the sliding sleeve 61 moves linearly on the rotor disk 41, the guide pin block 46 is forced to rotate along the conversion groove 611 due to the cooperation between the conversion groove 611 and the guide pin block 46. This causes the rotating sleeve 62 to rotate relative to the rotor disk 41. In other words, the linear motion of the piston cylinder 7 is converted into the rotational motion of the central wheel 44 through the conversion mechanism 6.

[0046] like Figure 8 and Figure 11 As shown, in some embodiments, a plug 612 is provided at one end of the sliding sleeve 61 near the rotor disk 41, and a plug hole 412 is provided on the rotor disk 41 extending axially. The plug 612 is inserted into and slidably installed in the plug hole 412, so that the sliding sleeve 61 slides and engages with the rotor disk 41 along the axial direction of the rotor disk 41.

[0047] like Figure 2As shown, in some embodiments, the outer peripheral wall of the sliding sleeve 61 is provided with an annular groove 613, and the connecting frame 63 is provided with a portion that is sleeved and slidably fitted in the annular groove 613, thereby realizing the rotatable connection between the connecting frame 63 and the sliding sleeve 61.

[0048] like Figure 1 As shown, in some embodiments, a drive shaft 2 is also included, which extends at least partially into the inner cavity of the shell 1, and the rotor disk 41 is fixedly connected to the drive shaft 2, thereby driving the rotor disk 4 to achieve rotational motion through the drive shaft 2.

[0049] like Figure 4 As shown, in some embodiments, the stator teeth 32 on the stator disk 31 have two rings, but are not limited to this. The two rings of stator teeth 32 are arranged in two rings, but are not limited to this, at a radial interval along the stator disk 31. At the same time, the rotor teeth 5 on the rotor disk 41 have two rings, but are not limited to this. When the stator tooth disk 3 and the rotor tooth disk 4 are installed in place, the rotor teeth 5 and the stator teeth 32 are alternately distributed in the radial direction to achieve a shearing effect on the object.

[0050] In some embodiments, the circulating emulsifying pump for preparing conductive slurry in this invention may also be provided with the emulsifying pump structure of the lithium-ion battery conductive slurry micro-nano dispersion system and preparation method disclosed in patent number 2024111662574, so that the size of the stator tooth gap 33 can also be adjusted to increase the adjustment range.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
