Description

Technical Field

[0001] The utility model relates to the technical field of filtration, in particular to a filtration component and a filtration device. Background Art

[0002] In the production and manufacturing process of lithium batteries, the coating operation is a crucial link, and its quality directly affects the performance and quality of the final product. In order to improve the quality of the slurry and the finished product, it is necessary to filter the slurry. The existing slurry filtration method is to let the flowing slurry pass through the screen of a capsule filter for filtration. This filtration method has the following defects:

[0003] 1. Low usage efficiency. The filter screen design of this type of filter usually can only adapt to one specification of slurry. When the production demand changes and different specifications of slurry need to be filtered, the operator must manually remove and replace the filter screen. This process not only takes time and effort, but also greatly reduces the continuous operation ability of the production line and increases the production cost.

[0025] Embodiment 1:

[0026] See the appendix Figures 1 to 3 . This embodiment provides a filter assembly, such as Figure 1As shown in the figure, it includes a first filter cartridge 1 and a second filter cartridge 2. The first filter cartridge 1 and the second filter cartridge 2 are attached to each other, and the second filter cartridge 2 is sleeved on the first filter cartridge 1. The first filter cartridge 1 and the second filter cartridge 2 extend in the longitudinal direction. For example, the first filter cartridge 1 and the second filter cartridge 2 can be cylindrical structures with open upper ends. A number of first filter holes 11 are provided on the side wall of the first filter cartridge 1, and a number of second filter holes 21 are provided on the side wall of the second filter cartridge 2.

Preferably, the first filter holes 11 and the second filter holes 21 are evenly arranged on the first filter cartridge 1 and the second filter cartridge 2 respectively. The first filter holes 11 and the corresponding second filter holes 21 together form a filtering channel for filtering the slurry. When filtering the slurry, the slurry to be filtered can flow out through the filtering channel from the inside of the first filter cartridge 1. The relative positions of the first filter cartridge 1 and the second filter cartridge 2 can be adjusted. Specifically, the first filter cartridge 1 and the second filter cartridge 2 rotate around the central axis in the longitudinal direction to change the relative positions, and the first filter cartridge 1 changes the size of the filtering channel formed by the first filter holes 11 and the corresponding second filter holes 21 by adjusting its position relative to the second filter cartridge 2.

[0027] The filtering assembly provided by the present utility model further includes a positioning device. The positioning device is adapted to selectively engage and fix the first filter cartridge 1 and the second filter cartridge 2 at a plurality of optional positions to position the relative positions of the first filter cartridge 1 and the second filter cartridge 2. For example, the positioning device can be a convex block and a number of grooves. A convex block can be provided on one of the first filter cartridge 1 and the second filter cartridge 2, and a number of grooves can be provided on the other. The convex block can be selectively engaged in different grooves, so that the relative positions of the first filter cartridge 1 and the second filter cartridge 2 are changed, thereby changing the size of the filtering channel formed by the first filter holes 11 and the corresponding second filter holes 21, and realizing the adjustment of the size of the filtering channel. Among them, the number and the setting positions of the convex block and the number of grooves can be determined according to specific situations, and the pore diameter sizes and the arrangement of the first filter holes 11 and the second filter holes 21 can also be determined according to specific situations.

For example, the first positioning portion is provided on the first filter cartridge 1 and the second positioning portion is provided on the second filter cartridge 2, or the first positioning portion is provided on the second filter cartridge 2 and the second positioning portion is provided on the first filter cartridge 1. By cooperating with different second positioning portions, the first positioning portion realizes the positioning of the first filter cartridge 1 and the second filter cartridge 2 at different relative positions.

[0031] Specifically, the upper edge of the first filter cartridge 1 is provided with a first end face 12, and the upper edge of the second filter cartridge 2 is provided with a second end face 22. The first end face 12 overlaps on the second end face 22, so that the second filter cartridge 2 can be sleeved outside the first filter cartridge 1.

The bolt 5 can be fixedly connected to the first end face 12, or by providing a positioning hole 13 on the first end face 12, the bolt 5 is detachably connected to the first end face 12 through the positioning hole 13. The second positioning portion is a plurality of threaded holes 23 provided on the second end face 22, and the bolt 5 is selectively connected to one of the threaded holes 23. Before filtration, determine the connection position of the bolt 5 and one of the threaded holes 23 as needed, and fixedly connect through the bolt 5; when the filtration channel needs to be adjusted, loosen the bolt 5, rotate the first filter cartridge 1 or the second filter cartridge 2, and connect the bolt 5 to the threaded holes 23 at other positions, so that the size of the filtration channel jointly formed by the first filter cartridge 1 and the second filter cartridge 2 meets the requirements.

[0032] Embodiment Three:

[0033] See attachment Figures 1 to 3 . On the basis of the second embodiment, this embodiment also provides a filtering device, as Figure 2 shown, including a housing and the filtering assembly in the second embodiment above. Among them, the housing has a chamber, the filtering assembly is arranged inside the housing, and a filtrate channel is formed between the outside of the filtering assembly and the inner wall of the housing. When filtering the slurry, the slurry to be filtered can pass through the filtering channel jointly formed by the first filter holes 11 and the second filter holes 21 from the inside of the first filter cartridge 1, flow out into the filtrate channel, and the filtered slurry can be temporarily stored in the housing or reused.

[0034] Specifically, the housing may include a cylinder body 3 and a cover body 4 covering the upper end of the cylinder body 3.

Specifically, a connecting step 31 is provided at the upper end of the inner side wall of the cylinder body 3, and the second end face 22 overlaps on the connecting step 31. Preferably, the upper end face of the connecting step 31 is slightly lower than the upper end face of the cylinder body 3. Among them, a liquid inlet is further provided on the cover body 4, and a liquid outlet is provided at the bottom of the cylinder body 3. The liquid inlet is communicated with the inside of the first filter cartridge 1, and the liquid outlet is communicated with the filtrate channel.

Then, the filtration assembly composed of the first filter cartridge 1 and the second filter cartridge 2 is installed in the cylinder body 3, and the cover body 4 is installed. The slurry to be filtered flows into the filtration assembly from the liquid inlet on the cover body 4, is filtered by the filtration assembly, and finally flows out from the liquid outlet at the bottom of the cylinder body 3 for secondary utilization.

[0036] Example 4:

[0037] See Appendix Figures 1 to 3 On the basis of Example 3, in this example, the filtration device further includes a stirring mechanism. The stirring mechanism is fixedly or detachably connected to the cover body 4, and the stirring mechanism can be used to stir the slurry in the first filter cartridge 1 to accelerate the filtration rate. It can be understood that in this example, the specific structure of the stirring mechanism is not limited, and the stirring mechanism can be realized by using existing technologies.

[0038] Furthermore, in this example, the filtration device further includes a fixing mechanism. The fixing mechanism can be used to fix the relative positions of the cylinder body 3 and the filtration assembly, preventing the filtration assembly from moving under the influence of external forces during the stirring process of the stirring mechanism and affecting the stability of the device.

[0039] Specifically, as Figure 3 shown, the fixing mechanism may include a fixing member 6. There is a connection hole 32 at the upper end of the outer side wall of the cylinder body 3, and the connection hole 32 is located above the connection step 31.

The connection hole 32 and the connection groove 24 correspond to each other, and the fixing member 6 connects the connection hole 32 and the connection groove 24. For example, the connection hole 32 can be a stepped hole with threads inside. The fixing member 6 can be a long bolt. After the fixing member 6 passes through the connection hole 32, it is inserted into the connection groove 24 and is fixedly connected to the connection hole 32 by threads to prevent the fixing member 6 from loosening. It can be understood that in this example, the specific structures of the fixing member 6, the connection hole 32, and the connection groove 24 are not limited.

[0040] Example 5:

[0041] See Appendix Figures 1 to 3 On the basis of Example 4, in this example, the filtration device further includes a cleaning mechanism. The cleaning mechanism can be used to clean the filtration assembly.

[0042] Specifically, the cleaning mechanism includes a cleaning member and a driving component. The cleaning member is detachably connected to the cover body 4. When cleaning is required, the cleaning member is installed on the cover body 4 to clean the filter component; during normal filtration, the cleaning member can be detached to prevent affecting normal filtration. One end of the cleaning member extends between the cylinder body 3 and the filter component. A cleaning member accommodation cavity 8 is provided in the cylinder body 3. The cleaning member can rotate under the action of an external force, and the outer wall of the filter component is in contact with the cleaning member. The driving component is used to drive the filter component to rotate. Specifically, the driving component may include a driving motor and a first gear 7 fixedly connected to the output shaft of the driving motor. The driving motor is detachably arranged on the cover body 4 through a driving motor mounting hole 9. A rack meshing with the first gear 7 is provided on the side wall of the second end face 22. The driving motor is used to drive the first gear 7 to rotate so as to drive the filter component to rotate. The cleaning member can be connected to the output shaft of the driving motor, so that the driving motor can also drive the cleaning member to rotate simultaneously.

[0043] When the filter component needs to be cleaned: At this time, loosen the fixing member 6 so that the relative positions of the cylinder body 3 and the filter component are not fixed, and the filter component can rotate relative to the cylinder body 3; and install the cleaning member in the cylinder body 3, and drive the first gear 7 to rotate through the driving motor, so that the first gear 7 drives the second filter cylinder 2 to rotate, enabling the cleaning member to clean the outer wall of the second filter cylinder 2.
