[0043] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0044] It should be noted that if a directional indication is involved in the embodiments of the present invention, the directional indication is only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0045] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0046] At present, K value is an extremely important indicator of lithium batteries. K value refers to the voltage drop of the battery per unit time, usually expressed in mV / d, and is an indicator used to measure the self-discharge rate of lithium batteries. The battery slurry may contain magnetic impurities such as iron, which will affect the battery performance and ultimately make the battery K value unsatisfactory. Therefore, the process of removing magnetic impurities is required in the production process of the battery slurry to remove the magnetic impurities and ultimately achieve the purpose of improving the K value of the battery cell.

[0047] Existing battery slurry iron removal equipment generally uses a magnetic bar, which is inserted into the battery slurry to absorb the magnetic impurities in the battery slurry. The magnetic bar is then taken out and the scraper mechanism sleeved on the outer side of the magnetic bar moves up and down to clean the magnetic bar. However, in order to prevent the scraper from separating from the magnetic bar, the scraper usually cannot move to the bottom of the magnetic bar, which limits the range of movement of the scraper and easily forms a cleaning dead zone at the bottom of the magnetic bar.

[0048] Based on this, the utility model provides a magnetic rod cleaning device for slurry iron removal equipment, aiming to solve the problem that the existing magnetic rod cleaning device cannot clean the bottom of the magnetic rod. Figures 1 to 4 A schematic diagram of the structure of the magnetic rod cleaning device provided by the utility model; Figure 5 This is a schematic structural diagram of the slurry iron removal arrangement provided by the utility model.

[0049] See also Figures 1 to 4 The magnetic rod cleaning device 100 includes a mounting base 1 and a scraper head 2. The mounting base 1 is formed with a mounting hole 13 extending in the up-down direction. The side wall of the mounting base 1 is provided with an air supply channel 14. The air supply channel 14 is connected to the mounting hole 13. The scraper head 2 is arranged in the mounting hole 13. The scraper head 2 is provided with an iron scraping hole 21 for the magnetic rod 420 to pass through. The scraper head 2 is extended in the up-down direction to form a purge channel 15 for gas flow with the mounting base 1, so as to guide the gas in the air supply channel 14 to purge and remove iron from the magnetic rod 420.

[0050] In the technical solution of the utility model, the magnetic bar 420 is inserted into the scraping hole 21, so that when the mounting seat 1 moves in the up-down direction, the scraping head 2 can remove iron from the magnetic bar 420, and the air supply channel 14 is connected to the mounting hole 13, so that after the mounting seat 1 moves downward to the lower limit position, air is supplied to the mounting hole 13, and the scraping head 2 is extended in the up-down direction to form a purge channel 15 for gas flow with the mounting seat 1, so as to guide the high-pressure gas flowing in the horizontal direction to flow downward, so as to purge the bottom of the magnetic bar 420. Impurities such as iron filings are blown away to prevent impurities from adhering to the bottom of the magnetic rod 420. In this way, the scraper head 2 is set to remove iron from the magnetic rod 420 in the scraper hole 21. At the same time, the air supply channel 14 is set to supply air to the mounting hole 13. Under the guidance of the scraper head 2, the gas can blow away impurities such as iron filings at the bottom of the magnetic rod 420 to prevent impurities from adhering to the cleaning dead zone at the bottom of the magnetic rod 420, thereby solving the problem that the existing magnetic rod cleaning device 100 cannot clean the bottom of the magnetic rod 420.

[0051] Furthermore, in order to improve the purging effect of the airflow, in this embodiment, the outer side wall of the scraper head 2 is tapered downward, which, on the one hand, allows the airflow to smoothly transition from horizontal flow to vertical flow, so as not to reduce the flow loss of the gas, which is conducive to improving the flow rate of the gas, and on the other hand, allows the airflow to converge toward the center of the scraper head 2, thereby helping to improve the purging effect of the airflow. In another embodiment, the inner diameter of the mounting hole 13 is tapered downward, so that the airflow can converge toward the center of the scraper head 2, thereby helping to improve the purging effect of the airflow.

[0052] It should be noted that the above two related technical features: "the outer wall of the scraper head 2 is tapered downward" and "the inner diameter of the mounting hole 13 is tapered downward" can be set either alone or at the same time. Obviously, setting them at the same time will have a better effect.

[0053] In some embodiments of the utility model, the outer wall of the scraping head 2 is formed with a mounting boss 31, and correspondingly, the inner wall of the mounting hole 13 is formed with a mounting groove 32, and the mounting boss 31 cooperates with the mounting groove 32 to install the scraping head 2 on the mounting seat 1, wherein the air supply channel 14 is connected to the mounting groove 32, so that the scraping head 2 is installed on the mounting seat 1 by setting the mounting boss 31 and the mounting groove 32 that cooperate with each other.

[0054] Furthermore, there are multiple ways of connecting the mounting boss 31 and the mounting groove 32. The mounting boss 31 can be fixedly mounted on the mounting groove 32 or movably mounted on the mounting groove 32, and the present invention does not limit this. However, if the mounting boss 31 is fixedly mounted on the mounting groove 32, when the tank cover 410 of the slurry iron removal equipment 1000 drives the magnetic rod 420 to be completely immersed in the tank body 300, the slurry in the tank body 300 is easy to enter the airway, which will affect the purging effect of the airflow. For this reason, in the present embodiment, the mounting boss 31 is movably mounted on the mounting seat 1 in the up and down directions. Within its movable stroke, the mounting boss 31 has an open position and a sealed position. When the mounting boss 31 is in the open position, the mounting boss 31 can open the purging channel 15. When the scraper head 2 is in the sealed position, the mounting boss 31 can close the purging channel 15. When the magnetic rod 4 When 20 is completely immersed in the tank body 300, the mounting boss 31 moves to the sealing position to close the purge channel 15. When the mounting seat 1 moves downward to the lower limit position, the mounting boss 31 moves to the opening position to open the purge channel 15. In this way, through the movement of the mounting boss 31, when the magnetic rod 420 is immersed in the tank body 300, the purge channel 15 is closed to prevent the slurry in the tank body 300 from entering the airway of the mounting seat 1. When the mounting seat 1 moves downward to the lower limit position, the purge channel 15 is opened, so that the high-pressure airflow can purge the bottom of the magnetic rod 420 to prevent impurities such as iron filings from adhering to the bottom of the magnetic rod 420.

[0055] In some embodiments of the utility model, the upper end of the scraper head 2 extends upward to the outside of the mounting hole 13 to form a driving part 22. The driving part 22 is used to drive the scraper head 2 to move downward to the sealing position when the tank cover 410 of the slurry iron removal equipment 1000 abuts against the mounting seat 1. When the tank cover 410 moves downward to immerse the magnetic rod 420 into the tank body 300, the driving part 22 can abut against the tank cover 410 to drive the scraper head 2 to move downward to the sealing position under the drive of the tank cover 410. In this way, by setting the driving part 22, the scraper head 2 can move under the drive of the tank cover 410, so as to utilize the power of the tank cover 410 to drive the scraper head 2 to close the purge channel 15 to prevent slurry from entering the air passage of the mounting seat 1.

[0056] It should be noted that when the mounting seat 1 moves downward to allow the scraper head 2 to clean the magnetic rod 420, the scraper head 2 will move upward to the open position under the action of friction, so that the mounting boss 31 can open the purge channel 15, so there is no need to add a driving structure to drive the scraper head 2 to move upward.

[0057] In some embodiments of the utility model, the upper end of the mounting boss 31 is flushly arranged to abut against the upper side wall of the mounting groove 32. On the one hand, it can limit the upward movable stroke of the mounting boss 31, and on the other hand, it can increase the contact area between the mounting boss 31 and the upper side wall of the mounting groove 32, so as to close the gap between the mounting boss 31 and the upper side wall of the mounting groove 32 to prevent high-pressure airflow from flowing upward, which not only helps to improve the sealing between the mounting boss 31 and the mounting groove 32, but also facilitates the subsequent setting of the seal 4.

[0058] In some embodiments of the utility model, the lower end of the mounting boss 31 is flushly arranged to abut against the lower side wall of the mounting groove 32. On the one hand, it can limit the downward movement of the mounting boss 31, and on the other hand, it can increase the contact area between the mounting boss 31 and the lower side wall of the mounting groove 32, so as to close the gap between the mounting boss 31 and the lower side wall of the mounting groove 32 to prevent slurry from entering the purge channel 15, which helps to improve the sealing between the mounting boss 31 and the mounting groove 32 and facilitates the subsequent setting of the seal 4.

[0059] It should be noted that the above two related technical features: "the upper end of the mounting boss 31 is flush with the mounting boss 31" and "the lower end of the mounting boss 31 is flush with the mounting boss 31" can be set either alone or at the same time. Obviously, setting them at the same time will have a better effect.

[0060] In some embodiments of the utility model, a seal 4 is provided between the mounting groove 32 and the mounting boss 31, and the seal 4 is provided on the upper side wall of the mounting groove 32 and the upper end surface of the mounting boss 31. In this way, by providing the seal 4, the gap between the mounting boss 31 and the upper side wall of the mounting groove 32 is closed to prevent high-pressure airflow from flowing upward, thereby helping to improve the sealing between the mounting boss 31 and the mounting groove 32.

[0061] In some embodiments of the present invention, a seal 4 is provided between the mounting groove 32 and the mounting boss 31, and the seal 4 is provided on the lower side wall of the mounting groove 32 and the lower end surface of the mounting boss 31. Thus, by providing the seal 4, the gap between the mounting boss 31 and the lower side wall of the mounting groove 32 is closed to prevent slurry from entering the purge channel 15, which helps to improve the sealing between the mounting boss 31 and the mounting groove 32. It is understandable that there are many types of seals 4, and the seals 4 can be sealing rings 5, sealing pads, etc., and the present invention does not limit this.

[0062] It should be noted that the above two related technical features: "the seal 4 is arranged on the upper side wall of the mounting groove 32 and the upper end surface of the mounting boss 31", "the seal 4 is arranged on the lower side wall of the mounting groove 32 and the lower end surface of the mounting boss 31" can be set either one or at the same time. Obviously, setting them at the same time will have a better effect.

[0063] In some embodiments of the utility model, the mounting seat 1 includes an upper mounting plate 11 and a lower mounting plate 12, the upper mounting plate 11 is provided with a first mounting sub-hole, the lower mounting plate 12 is detachably mounted on the upper mounting plate 11, and the lower mounting plate 12 is provided with a second mounting sub-hole that is connected to the first mounting sub-hole, wherein the mounting hole 13 includes the first mounting sub-hole and the second mounting sub-hole, and the mounting groove 32 is provided between the upper mounting plate 11 and the lower mounting plate 12. In this way, a detachable connection method is adopted to facilitate the loading and unloading of the lower mounting plate 12, so that the upper mounting plate 11 can jointly form the mounting groove 32 with the lower mounting plate 12, thereby facilitating the installation of the scraper head 2 on the mounting seat 1.

[0064] In some embodiments of the present invention, a sealing ring 5 is provided between the upper mounting plate 11 and the lower mounting plate 12 to seal the gap between the upper mounting plate 11 and the lower mounting plate 12 , thereby helping to improve the sealing performance of the mounting seat 1 .

[0065] In some embodiments of the utility model, the scraper head 2 and the mounting hole 13 are arranged in a one-to-one correspondence as a scraper group, and a plurality of scraper groups are arranged, and the plurality of scraper groups are arranged at circumferential intervals along the mounting seat 1. In this way, by setting a plurality of scraper groups, a plurality of magnetic rods 420 can be cleaned at the same time, so that the magnetic rod cleaning device 100 can be adapted to the magnetic rod 420, thereby helping to improve the versatility of the magnetic rod cleaning device 100.

[0066] Furthermore, there are multiple ways to supply air to the multiple mounting holes 13. It can be that multiple mounting holes 13 are supplied with air respectively through multiple air supply channels 14, or that multiple mounting holes 13 are supplied with air simultaneously through one air supply channel 14. The utility model does not limit this. Specifically, in the present embodiment, an air supply cavity 16 and multiple ventilation channels 17 connected to the air supply cavity 16 are provided in the mounting seat 1. The multiple ventilation channels 17 correspond to and connect multiple mounting holes 13 respectively, wherein the air supply channel 14 is connected to the air supply cavity 16. In this way, by providing multiple ventilation channels 17, air can be supplied to the multiple mounting holes 13 respectively, and by providing the air supply cavity 16, the pressure fluctuation in the air supply channel 14 can be balanced, so that the pressure in the multiple ventilation channels 17 remains consistent, so as to prevent the air pressure in some mounting holes 13 from being too low, affecting the purge effect of the airflow. Furthermore, the air supply cavity 16 is disposed in the middle of the mounting base 1 so that the lengths of the plurality of ventilation channels 17 are the same, so that the flow of the plurality of ventilation channels 17 is kept consistent, thereby making the air pressure in the plurality of ventilation channels 17 consistent.

[0067] In some embodiments of the present invention, the material of the scraper head 2 includes PTFE rubber. Since PTFE rubber has certain strength and toughness, and also has good corrosion resistance and aging resistance, the use of PTFE rubber can not only ensure that the scraper head 2 can clean the magnetic rod 420, but also improve the service life of the scraper head 2. Of course, in other embodiments, the material of the scraper head 2 can also be EPDM rubber, etc., and the present invention does not limit this.

[0068] In some embodiments of the utility model, the scraper hole 21 is tapered from top to bottom. Thus, the tapered setting not only facilitates the insertion of the magnetic rod 420 into the scraper hole 21 , but also enables the scraper head 2 to be close to the magnetic rod 420 , thereby helping to improve the cleaning effect of the scraper head 2 on the magnetic rod 420 .
