Description

Technical Field

[0001] This utility model relates to the field of slurry filtration, and in particular to a multi-stage filtration structure for stirred slurry particles. Background Technology

[0002] In the production process of battery slurry, the quality of the slurry plays a crucial role in the performance of the battery. Battery slurry typically contains various particulate materials. To ensure the uniformity and stability of the slurry, and to avoid the adverse effects of large particulate impurities on battery performance, the slurry must undergo efficient and precise filtration.

[0003] Traditional slurry filtration devices often employ single-pore size filters or simple filtration structures, which are insufficient for the graded filtration of particles of different sizes in the slurry. In actual production, the particle size distribution in the slurry is quite extensive. If impurities of different particle sizes cannot be effectively removed, it may lead to uneven electrode coating, increased internal resistance, and capacity decay, severely impacting battery quality and lifespan. Furthermore, during filtration, particles in the slurry tend to accumulate on the filter screen, causing blockage, reducing filtration efficiency, and increasing filtration costs and time. Traditional cleaning methods often require manual cleaning during machine shutdown or the use of complex automatic cleaning devices, which are not only inconvenient to operate but also disrupt production continuity.

[0004] Therefore, there is an urgent need for a multi-stage filtration structure for agitated slurry particles to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a multi-stage filtration structure for stirred slurry particles, which can achieve multi-stage filtration of battery slurry particles and has an automatic cleaning function, thereby improving the filtration quality and production efficiency of battery slurry.

[0006] To solve the above-mentioned technical problems, this utility model provides a multi-stage filtration structure for stirred slurry particles, including a cavity, a filter cylinder, a fluid-driven rotating component, a cleaning roller, and a linkage component;

[0007] The filter cylinder is disposed inside the cavity and has multiple annular filter screens with filter pore diameters decreasing from the outside to the inside.

[0008] The fluid-driven rotating component is rotatably installed inside the cavity and is concentrically arranged with the filter cartridge, and is sleeved on the outside of the filter cartridge;

[0009] The fluid-driven rotating component is located on the same horizontal plane as the feed inlet of the cavity, so as to rotate by means of the impact of the slurry;

[0010] The cleaning roller is disposed on the inner wall of the fluid-driven rotating component and is capable of rotating relative to the fluid-driven rotating component, and is in contact with the outermost surface of the annular filter screen of the filter cylinder;

[0011] The linkage is disposed between the cleaning roller and the outer wall of the filter cylinder, so that the cleaning roller rotates synchronously with the fluid-driven rotating component.

[0012] Furthermore, the fluid-driven rotating component includes a rotating ring and multiple arc-shaped blocks;

[0013] The arc-shaped blocks are arranged in a ring at equal intervals on the lower surface of the rotating ring, and are used to contact the slurry input into the cavity, and drive the rotating ring to rotate under the impact of the slurry.

[0014] Furthermore, a bracket is fixedly installed on the inner wall of the rotating ring;

[0015] The cleaning roller is rotatably connected to the bracket via a connecting shaft, so as to rotate relative to the fluid-driven rotating component.

[0016] Furthermore, multiple cleaning rollers are arranged in a ring at equal intervals with the axis of the filter cylinder as the center.

[0017] Furthermore, the linkage includes a gear ring and a gear;

[0018] The toothed ring is fixedly installed on the outer wall of the top end of the filter cylinder;

[0019] The gear is fixedly mounted on the outer wall of the connecting shaft and meshes with the gear ring.

[0020] Furthermore, both the gear ring and the gear are located above the feed inlet of the cavity.

[0021] Furthermore, the cavity includes a sleeve and an end cap detachably connected to the sleeve;

[0022] The inner wall of the sleeve is provided with an annular support portion for mounting the fluid-driven rotating component;

[0023] The filter cartridge is inserted into the bottom wall of the inner cavity of the cavity, and the inner diameter of the annular support is larger than the outer diameter of the filter cartridge on which the toothed ring is installed, so that when the end cap is opened, the filter cartridge can be pulled out along the opening direction of the sleeve.

[0024] Furthermore, two annular filters are provided.

[0025] Furthermore, multiple chambers are formed between the two annular filter screens and the inner wall of the cavity, and each of the multiple chambers is provided with a first filter discharge port, a second filter discharge port, and a discharge port.

[0026] Compared with the prior art, the present invention has at least the following beneficial effects:

[0027] By setting up a filter cylinder with multiple annular filter screens with decreasing pore size from the outside to the inside, a multi-stage filtration function is achieved. Furthermore, by incorporating a fluid-driven rotating component, a cleaning roller, and a linkage between the cleaning roller and the filter cylinder, the fluid-driven rotating component is driven to rotate under the impact of the slurry input. With the cooperation of the linkage, the cleaning roller rotates around the filter cylinder while also rotating on its own axis, achieving a self-cleaning function for the outermost annular filter screen. This effectively reduces the frequency of filter cylinder cleaning, thereby improving the filtration quality and production efficiency of battery slurry.

[0028] Furthermore, since the rotation and self-rotation of the cleaning roller are accomplished by the impact force of the slurry, no additional power input equipment is required, thus achieving the goal of energy saving and efficiency improvement. Attached Figure Description

[0032] The multi-stage filtration structure for stirred slurry particles of this utility model will be described in more detail below with reference to the schematic diagrams, which illustrate preferred embodiments of this utility model. It should be understood that those skilled in the art can modify the utility model described herein while still achieving the advantageous effects of this utility model. Therefore, the following description should be understood as being of general knowledge to those skilled in the art and is not intended to limit this utility model.

[0033] The present invention will be described in more detail below by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0034] like Figure 1 and Figure 2As shown in the figure, this utility model embodiment proposes a multi-stage filtration structure for stirred slurry particles, including a cavity 1, a filter cylinder 2, a fluid-driven rotating component 3, a cleaning roller 4, and a linkage component 5.

[0035] The filter cylinder 2 is disposed inside the cavity 1 and has multiple annular filter screens 21 with filter pore diameters decreasing from the outside to the inside. By setting multiple annular filter screens 21 with different filter pore diameters arranged sequentially from the outside to the inside, multi-stage filtration of the slurry can be achieved, thereby improving the filtration quality of the slurry and ensuring the quality and service life of the subsequent battery.

[0036] The fluid-driven rotating component 3 is rotatably installed inside the cavity 1 and is concentrically arranged with the filter cylinder 2, and is sleeved on the outside of the filter cylinder 2. That is, the fluid-driven rotating component 3 can rotate around the filter cylinder 2, thereby providing power for subsequent cleaning of the annular filter screen 21 on the outside of the filter cylinder 2.

[0037] It should be noted that the fluid-driven rotating component 3 and the feed inlet of the cavity 1 are located on the same horizontal plane so as to rotate by means of the impact of the slurry. That is, when the slurry is input, it can drive the fluid-driven rotating component 3 to rotate, so as to provide rotational power for cleaning the cleaning roller 4.

[0038] Specifically, the cleaning roller 4 is disposed on the inner wall of the fluid-driven rotating component 3 and is able to rotate relative to the fluid-driven rotating component 3, and is in contact with the outermost surface of the annular filter screen 21 of the filter cylinder 2.

[0039] In addition, the linkage 5 is disposed between the cleaning roller 4 and the outer wall of the filter cylinder 2, so that the cleaning roller 4 rotates synchronously with the fluid-driven rotating component 3 and rotates on its own. That is, the cleaning roller 4 not only rotates to clean the outermost annular filter screen 21 of the filter cylinder 2, but also rotates on its own to clean, so as to further improve the cleaning effect.

[0040] This device achieves multi-stage filtration by setting up a filter cylinder 2 with multiple annular filter screens 21 having decreasing pore sizes from the outside to the inside. By setting up a fluid-driven rotating component 3, a cleaning roller 4, and a linkage component 5 between the cleaning roller 4 and the filter cylinder 2, when slurry is input, the fluid-driven rotating component 3 can be rotated under the impact of the slurry. With the cooperation of the linkage component 5, the cleaning roller 4 can rotate around the filter cylinder 2 and also rotate on its own axis, realizing the self-cleaning function of the outermost annular filter screen 21. This effectively reduces the number of times the filter cylinder 2 needs to be cleaned, thereby improving the filtration quality and production efficiency of battery slurry.

[0041] Furthermore, since the rotation and self-rotation of the cleaning roller 4 are accomplished by the impact force of the slurry, no additional power input equipment is required, thus achieving the purpose of energy saving and efficiency improvement.

[0042] In one embodiment, a specific fluid-driven rotating component 3 is also proposed to better convert the impact force of the slurry into the power for the cleaning roller 4 to rotate and clean. Specifically, the fluid-driven rotating component 3 includes a rotating ring 31 and a plurality of arc-shaped blocks 32.

[0043] The arc-shaped blocks 32 are arranged in a ring at equal intervals on the lower surface of the rotating ring 31, and are used to contact the slurry input into the cavity 1, and drive the rotating ring 31 to rotate under the impact of the slurry.

[0044] It should be noted that the center of the arc-shaped block 32 is offset from the center of the filter cylinder 2, so that when the arc-shaped block 32 is subjected to the impact force of the slurry, it can provide a component force to the rotating ring 31 to rotate around its axis, thereby driving the rotating ring 31 to rotate and completing the power supply to the cleaning roller 4.

[0045] In other embodiments, the arc-shaped block 32 can also be configured as an axial flow blade structure, i.e., in the shape of a propeller. This is existing technology and will not be described in detail here.

[0046] In a further embodiment, the rotating ring 31 is further defined to facilitate the installation between the cleaning roller 4 and the rotating ring 31.

[0047] Specifically, a bracket is fixedly installed on the inner wall of the rotating ring 31, and the cleaning roller 4 is rotatably connected to the bracket through a connecting shaft so as to rotate relative to the fluid-driven rotating component 3.

[0048] Furthermore, by setting up a bracket, a gap is formed between the cleaning roller 4 and the arc-shaped block 32 to prevent interference between the cleaning roller 4 and the arc-shaped block 32 when the cleaning roller 4 rotates.

[0049] In addition, multiple cleaning rollers 4 are arranged in a ring at equal intervals with the axis of the filter cylinder 2 as the center, in order to improve the cleaning effect.

[0050] In other embodiments, a specific linkage 5 is proposed so that when the rotating ring 31 drives the cleaning roller 4 to rotate, the cleaning roller 4 can rotate more effectively for cleaning, thereby improving the cleaning effect.

[0051] Specifically, the linkage 5 includes a gear ring 51 and a gear 52.

[0052] The toothed ring 51 is fixedly installed on the outer wall of the top of the filter cylinder 2, and the gear 52 is fixedly installed on the outer wall of the connecting shaft and meshes with the toothed ring 51, so that when the rotating ring 31 drives the cleaning roller 4 to make a circular motion around the toothed ring 51, the self-rotation function of the cleaning roller 4 is realized under the meshing action.

[0053] It should be noted that, in order to prevent the input of slurry from interfering with the gear 52 and the gear ring 51, the positions of the two are further defined, such as the gear ring 51 and the gear 52 being located above the feed inlet of the cavity 1, so as to avoid the influence of slurry on the gear ring 51 and the gear 52.

[0054] In other embodiments, the cavity 1 is further defined to facilitate the disassembly and removal of the filter cartridge 2 for periodic cleaning.

[0055] Specifically, the cavity 1 includes a sleeve 11 and an end cap 12 detachably connected to the sleeve 11.

[0056] The inner wall of the sleeve 11 is provided with an annular support portion 6 for mounting the fluid-driven rotating component 3.

[0057] Furthermore, the filter cylinder 2 is inserted into the bottom wall of the inner cavity of the cavity 1, and the inner diameter of the annular support 6 is larger than the outer diameter of the filter cylinder 2 on which the toothed ring 51 is installed, so that when the end cover 12 is opened, the filter cylinder 2 can be pulled out along the opening direction of the sleeve 11 to complete the disassembly and cleaning function, ensuring that the setting of the linkage 5 and the cleaning roller 4 does not affect the normal cleaning of the filter cylinder 2.

[0058] In this embodiment, two annular filter screens 21 are provided. The two annular filter screens 21 are separated from the inner wall of the cavity 1 to form multiple chambers. The multiple chambers are respectively provided with a first filter discharge port 7, a second filter discharge port 8 and a discharge port 9, so as to be used for impurity discharge and qualified slurry discharge, respectively.

[0059] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
