These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0057] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0058] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , Figure 1 This is a front view of a lithium battery mixer cleaning device provided in an embodiment of this application. Figure 2 yes Figure 1 The image shows a side view of the lithium battery mixer cleaning equipment. Figure 3 This is a schematic diagram illustrating the connection between the lower bucket and the first connecting valve according to an embodiment of this application. Figure 4 This is a system block diagram of a control component, a slurry mixing component, a spraying component, a first connecting valve, and a waste liquid recovery component provided in an embodiment of this application. The lithium battery mixer cleaning equipment may include: a support 100, an upper tank 200, a lower tank 300, a slurry mixing component 400, a spraying component 500, a first connecting valve 600, a waste liquid recovery component 700, and a control component 800.

[0059] In the lithium battery mixer cleaning equipment, both the upper tank 200 and the lower tank 300 can be connected to the support 100. The opening a1 of the upper tank 200 and the opening a2 of the lower tank 300 can be arranged opposite each other along the height direction of the support 100. The bottom of the lower tank 200 can have a discharge port b1. Here, when the upper tank 200 and the lower tank 300 are switched to the closed state, the lower tank 300 can move along the support 100 towards the upper tank 200 to connect the upper tank 200 and the lower tank 300; when the upper tank and the lower tank are switched to the open state, the lower tank 300 can move along the support 100 away from the upper tank 200 to separate the upper tank 200 and the lower tank 300. It should be noted that... Figure 1 and Figure 2 The upper bucket 200 and the lower bucket 300 are in a separate state.

[0060] The slurry mixing component 400 in the lithium battery mixer cleaning equipment can be connected to the upper tank 200, and the slurry mixing component 400 can be used to mix the slurry in the lower tank 300.

[0061] The spray assembly 500 in the lithium battery mixer cleaning equipment can be connected to the lower tank 300. The spray assembly 500 can spray a first cleaning agent with a preset pressure onto at least one of the inner wall of the upper tank 200, the inner wall of the lower tank 300, and the slurry mixing assembly 400.

[0062] The first connecting valve 600 in the lithium battery mixer cleaning equipment can be installed at the discharge port b1 at the bottom of the lower tank 300, and the first connecting valve 600 can have a slurry discharge port c1 and a liquid discharge port c2. For example, the first connecting valve 600 can be a three-way valve, and after the slurry mixing assembly 400 has finished mixing the slurry, the slurry can be discharged through the slurry discharge port c1.

[0063] The waste liquid recovery component 700 in the lithium battery mixer cleaning equipment can be connected to the first connecting valve 600 via the drain port c2. The waste liquid recovery component 700 can spray a second cleaning agent with a preset pressure onto at least one of the inner walls of the upper tank 200, the lower tank 300, and the slurry mixing component 400. For example, this second cleaning agent is the cleaning agent formed after cleaning the lithium battery mixer with the first cleaning agent; that is, the second cleaning agent is a secondary use of the first cleaning agent. For example, the first cleaning agent can be a liquid cleaning solvent mixed with NMP. Here, a flexible hose can be used to connect the waste liquid recovery component 700 and the drain port c2 of the first connecting valve 600.

[0064] The control component 800 in the lithium battery mixer cleaning equipment can be electrically connected to the slurry mixing component 400, the spraying component 500, the first connecting valve 600, and the waste liquid recovery component 700. Here, after receiving a control command from the operator, the control component 800 controls the slurry mixing component 400, the spraying component 500, the first connecting valve 600, and the waste liquid recovery component 700 to be in an operating state, or controls the slurry mixing component 400, the spraying component 500, the first connecting valve 600, and the waste liquid recovery component 700 to be in a stopped state.

[0065] In this embodiment, by integrating a spray assembly 500, a first connecting valve 600, and a waste liquid recovery assembly 700 into the lithium battery mixer, after the upper tank 200 and the lower tank 300 are in the closed state, the control assembly 800 can control the spray assembly 500 to open upon receiving an opening command. The spray assembly 500 can spray a first cleaning agent with a preset pressure onto at least one of the inner wall of the upper tank 200, the inner wall of the lower tank 300, and the slurry mixing assembly 400. After the spray assembly 500 sprays the first cleaning liquid for a preset cleaning time, the control assembly 800 controls the spray assembly 500 to stop working and simultaneously controls the opening of the drain port c2 of the first connecting valve 600 and the opening of the waste liquid recovery assembly 700. The waste liquid recovery assembly 700 uses a second cleaning agent to spray a second cleaning agent with a preset pressure onto at least one of the inner wall of the upper tank 200, the inner wall of the lower tank 300, and the slurry mixing assembly 400. In this way, the lithium battery mixer cleaning equipment can automatically clean the lithium battery mixer in a closed space when the upper tank 200 and the lower tank 300 are closed, avoiding operator contact with cleaning solvents (e.g., NMP solvent). The cleaning efficiency and effect are both good and safe and reliable, thus ensuring lithium battery production efficiency. Furthermore, there is no need to separate the upper tank 200 and the lower tank 300 for manual scraping and cleaning of parts, effectively avoiding waste liquid splashing and secondary pollution. The waste liquid after cleaning can also be recycled, reducing cleaning solvent consumption and lowering cleaning costs.

[0066] In summary, this application provides a lithium battery mixer cleaning device, which may include: a support, an upper tank, a lower tank, a slurry mixing assembly, a spray assembly, a first connecting valve, a waste liquid recovery assembly, and a control assembly. By integrating the spray assembly, the first connecting valve, and the waste liquid recovery assembly into the lithium battery mixer, after the upper and lower tanks are in the closed state, the control assembly can control the spray assembly to open upon receiving an opening command. The spray assembly can spray a first cleaning agent with a preset pressure onto at least one of the inner walls of the upper tank, the inner walls of the lower tank, and the slurry mixing assembly. After the spray assembly sprays the first cleaning liquid for a preset cleaning time, the control assembly controls the spray assembly to stop working and simultaneously controls the opening of the drain port of the first connecting valve and the waste liquid recovery assembly. The waste liquid recovery assembly uses a second cleaning agent discharged from the drain port to spray a second cleaning agent with a preset pressure onto at least one of the inner walls of the upper tank, the inner walls of the lower tank, and the slurry mixing assembly. In this way, the lithium battery mixer cleaning equipment can automatically clean the lithium battery mixer in a closed space when the upper and lower tanks are closed, avoiding operator contact with cleaning solvents (such as NMP solvent). The cleaning efficiency and effect are both good and safe and reliable, thus ensuring lithium battery production efficiency. Furthermore, there is no need to separate the upper and lower tanks and manually scrape the cleaning parts, effectively avoiding waste liquid splashing and secondary pollution. The waste liquid after cleaning can also be recycled, reducing cleaning solvent consumption and lowering cleaning costs.

[0067] Optional, please refer to Figure 2 , Figure 5 and Figure 6 , Figure 5 This is a partial structural schematic diagram of the lithium battery mixer cleaning equipment provided in the embodiments of this application. Figure 6 This is a top view of a lithium battery mixer cleaning device provided in an embodiment of this application. The spray assembly 500 in the lithium battery mixer cleaning device may include: an interconnected liquid delivery structure 501 and a plurality of first nozzles 502, the plurality of first nozzles 502 being fixedly connected to the side wall of the lower tank 300. A control assembly 800 may be electrically connected to the liquid delivery structure 501 to control the liquid delivery structure 501 to input a first cleaning agent into the inlet of each first nozzle 502, so that the first cleaning agent can be sprayed out from the outlet of the first nozzle 502. In this case, by providing the liquid delivery structure 501 and the plurality of first nozzles 502 in the spray assembly 500, the liquid delivery structure 501 can input the first cleaning agent to the inlet of the first nozzle 502 with a certain pressure, thereby causing the first cleaning agent to be sprayed out from the outlet of the first nozzle 502, effectively cleaning at least one of the inner wall of the lower tank 300, the inner wall of the upper tank 200, and the slurry mixing assembly 400.

[0068] In the embodiments of this application, such as Figure 5 and Figure 6As shown, the waste liquid recovery component 700 in the lithium battery mixer cleaning equipment may include: an interconnected waste liquid transfer structure 701 and a plurality of second nozzles 702. The plurality of second nozzles 702 may be fixedly connected to the side wall of the lower tank 300, and the plurality of second nozzles 702 and the plurality of first nozzles 502 may be symmetrically distributed along the central axis of the lower tank 300. The control component 800 may be electrically connected to the waste liquid transfer structure 701 to control the waste liquid transfer structure 701 to input a second cleaning agent into the inlet of the second nozzles 702, so that the second cleaning agent is sprayed out from the outlet of the second nozzles 702. In this configuration, by incorporating a waste liquid transfer structure 701 and multiple second nozzles 702 into the waste liquid recovery assembly 700, the waste liquid transfer structure 701 can introduce a second cleaning agent into the inlet of the second nozzle 702 at a certain pressure, thereby causing the second cleaning agent to be ejected from the outlet of the second nozzle 702. This effectively cleans at least one of the inner walls of the lower tank 300, the upper tank 200, and the slurry mixing assembly 400. Furthermore, the multiple second nozzles 702 and the multiple first nozzles 502 are symmetrically distributed along the central axis of the lower tank 300, allowing for repeated cleaning of the components within the lithium battery mixer. For example, the lower tank 300 can be cylindrical, and the corresponding upper tank 200 can also be cylindrical.

[0069] In this application, the number of the plurality of first nozzles 502 can be the same as the number of the plurality of second nozzles 702.

[0070] Optional, please refer to Figure 7 and Figure 8 , Figure 7 This is a partial structural schematic diagram of another lithium battery mixer cleaning device provided in an embodiment of this application. Figure 8This is a partial structural schematic diagram of another lithium battery mixer cleaning device provided in this application embodiment. The slurry mixing component 400 in the lithium battery mixer cleaning device may include: a planetary box 401, two sets of dispersion discs 402, and a stirring paddle 403. The planetary box 401 can be installed inside the upper tank 200 and electrically connected to the control component 800. The two sets of dispersion discs 402 can be located at two edges of the planetary box 401, respectively. The stirring paddle 403 can be located between the two sets of dispersion discs 402, and both the two sets of dispersion discs 402 and the stirring paddle 403 can be drivenly connected to the planetary box 401. The outlets of some of the multiple target nozzles can face the bottom central region of the planetary box 401, the outlets of another portion of the multiple target nozzles can face the side of the dispersion disc 402 closest to the planetary box 401, and the outlets of yet another portion of the multiple target nozzles can face the side of the dispersion disc 402 away from the planetary box 401. The multiple target nozzles can be any one of multiple first nozzles 502 and multiple second nozzles 702. In this way, some of the target nozzles positioned towards the bottom of the planetary housing 401 can effectively spray and wash the planetary housing 401 and the agitator 403, while the remaining target nozzles can effectively spray and wash the outer surfaces of the two sets of dispersion discs 402. It should be noted that the structure and working principle of the multiple first nozzles 502 are the same as those of the multiple second nozzles 702, and the outlet orientation angles of the multiple first nozzles 502 and the multiple second nozzles 702 located on the side wall of the lower tank 300 can be adjusted to adapt to different cleaning requirements.

[0071] For example, such as Figure 7 As shown, the planetary box 401 may have two dispersion shafts 401a corresponding to the two sets of dispersion disks 402, respectively. The length direction of each dispersion shaft 401a is parallel to the arrangement direction of the upper barrel 200 and the lower barrel 300. Each set of dispersion disks 402 can be fitted and fixed onto its corresponding dispersion shaft 401a. Here, the planetary box 401 can drive the two sets of dispersion disks 402 to revolve around the central axis of the lower barrel 300, and can also drive the two sets of dispersion disks 402 to rotate independently via the two dispersion shafts 401a.

[0072] In the embodiments of this application, such as Figure 7As shown, one set of dispersion disks 402 may include a first dispersion disk A1 and a second dispersion disk A2 arranged sequentially in a direction away from the planetary box 401, and another set of dispersion disks 402 may include a third dispersion disk A3 and a fourth dispersion disk A4 arranged sequentially in a direction away from the planetary box 401. The distance d1 between the third dispersion disk A3 and the planetary box 401 may be greater than the distance d2 between the first dispersion disk A1 and the planetary box 401, the distance d3 between the second dispersion disk A2 and the planetary box 401 may be greater than the distance d1 between the third dispersion disk A3 and the planetary box 401, and the distance d4 between the fourth dispersion disk A4 and the planetary box 401 may be greater than the distance d3 between the second dispersion disk A2 and the planetary box 401.

[0073] Please refer to Figure 2 , Figure 7 , Figure 9 and Figure 10 , Figure 9 This is a front view of a lithium battery mixer cleaning device provided in an embodiment of this application. Figure 10 This is a side view of the structural structure of a lithium battery mixer cleaning device provided in an embodiment of this application. Multiple target nozzles may include a first target nozzle P1, a second target nozzle P2, a third target nozzle P3, a fourth target nozzle P4, and a fifth target nozzle P5 arranged sequentially in a direction away from the planetary housing 401. The outlet of the first target nozzle P1 may face the central area of ​​the bottom of the planetary housing 401. The orthographic projection of the second target nozzle P2 on the target plane may be located between the orthographic projection of the first target nozzle P1 on the target plane and the orthographic projection of the first dispersing disk A1 on the target plane. The orthographic projection of the third target nozzle P3 on the target plane may be located between the orthographic projection of the third dispersing disk A3 on the target plane and the orthographic projection of the second dispersing disk A2 on the target plane. The orthographic projection of the fourth target nozzle P4 on the target plane may be located between the orthographic projection of the third target nozzle P3 on the target plane and the orthographic projection of the second dispersing disk A2 on the target plane. The orthographic projection of the fifth target nozzle P5 on the target plane may be located between the orthographic projection of the fourth dispersing disk A4 on the target plane and the bottom of the lower tank 300. The target plane M can be the plane containing the central axis L of the lower tank 300. In this way, through the reasonable distribution of multiple target nozzles, the cleaning agent sprayed from the multiple target nozzles with preset pressure can effectively clean the planetary box 401, the stirring paddle 403, and the dispersion disc 402, thereby improving the cleaning range and efficiency of the lithium battery mixer and ensuring a good cleaning effect.

[0074] Optional, such as Figure 9 and Figure 10As shown, the multiple target nozzles may further include an auxiliary nozzle P6, which is flush with the first target nozzle P1, and the outlet of the auxiliary nozzle P6 may face the central area of ​​the bottom of the planetary housing 401. Thus, by providing an auxiliary nozzle P6 flush with the first target nozzle P1 among the multiple target nozzles, the cleaning effect on the lithium battery agitator can be further improved. For example, when the lower tank 300 is cylindrical, the first target nozzle P1 and the auxiliary nozzle P6 are distributed circumferentially along the lower tank, and the arc formed by the connection of the first target nozzle P1 and the auxiliary nozzle P6 can correspond to a 90-degree radius.

[0075] In this application, the first target nozzle P1 and the auxiliary nozzle P6 can both be linear nozzles, and the second target nozzle P2, the third target nozzle P3, the fourth target nozzle P4 and the fifth target nozzle P5 can all be fan-shaped nozzles.

The liquid delivery structure 501 in the spray assembly 500 may include: a storage tank 501c, a first cleaning agent interface 501a, and a first pipeline 501b. The first cleaning agent interface 501a may be installed on the side wall of the lower tank 300. The first pipeline 501b may be connected to one end of the first cleaning agent interface 501a and the inlet of the plurality of first nozzles 502. The other end of the first cleaning agent interface 501a may be connected to the storage tank 501c. The liquid delivery structure may also include a first high-pressure pump 501d disposed between the storage tank 501c and the first cleaning agent interface 501a. The storage tank 501c may be used to store the first cleaning agent, and the first high-pressure pump 501d is electrically connected to the control assembly 800 and may be used to drive the first cleaning agent in the storage tank 501c to flow into the first pipeline 501b. In this way, a clean first cleaning agent can be stored in a storage tank 501c, and the first cleaning agent in the storage tank 501c can be sprayed out from the first nozzle 502 through the infusion structure 501, thereby using these first cleaning agents to clean the lithium battery mixer.

[0077] It should be noted that the other end of the first cleaning agent interface 501a can be connected to the storage tank 501c via a first connecting pipe 501e, and the first high-pressure pump 501d can be installed on the first connecting pipe 501e. For example, the infusion structure may further include: a first flow limiter 501f installed on the first connecting pipe 501e and located between the first high-pressure pump 501d and the first cleaning agent interface 501a. The first flow limiter 501f is electrically connected to a control component for adjusting the pressure of the first cleaning agent in the first pipe 501b by regulating the flow rate of the first cleaning agent passing through the first connecting pipe 501e.

[0078] In this application, as Figure 12 As shown, the infusion structure may further include a first switching valve 501g installed on the first cleaning agent port 501a, which can be used to control the opening and closing of the first cleaning agent port 501a. For example, the first switching valve can be a manual valve.

[0079] Optional, please refer to Figure 10 , Figure 13 and Figure 14 , Figure 13 This is a connection diagram of a waste liquid recovery component provided in an embodiment of this application. Figure 14 yes Figure 6A partially enlarged schematic diagram at point B. The waste liquid transfer structure 701 in the waste liquid recovery assembly 700 may include: a sedimentation tank 701a, a second cleaning agent interface 701b, and a second pipeline 701c. The second cleaning agent interface 701b may be installed on the side wall of the lower tank 300. The second pipeline 701c may be connected to one end of the second cleaning agent interface 701b and the inlet of a plurality of second nozzles 702. The other end of the second cleaning agent interface 701b may be connected to the sedimentation tank 701a. The waste liquid transfer structure 701 may also include a second high-pressure pump 701d disposed between the sedimentation tank 701a and the second cleaning agent interface 701b. The sedimentation tank 701a may be connected to the drain port c2 of the first connecting valve 600 and used to store the second cleaning agent. The second high-pressure pump 701d may be electrically connected to the control assembly 800 to drive the second cleaning agent in the sedimentation tank 701a to flow into the second pipeline 701c. In this way, the settling tank 701a can collect the first cleaning agent deposited in the lower tank 300 after cleaning the lithium battery mixer. After a certain period of sedimentation in the settling tank 701a, this first cleaning agent forms a second cleaning agent. Then, the second cleaning agent in the settling tank 701a is sprayed out through the second nozzle 702 via the waste liquid transfer structure 701, and this second cleaning agent is used to continue cleaning the lithium battery mixer. This allows for the reuse of the cleaning agent, effectively reducing the cleaning cost of the lithium battery mixer. Here, the second pipe 701c and the first pipe 501b can be connected, or, as shown in the figure, the second pipe 701c and the first pipe 501b can be disconnected.

[0080] It should be noted that the other end of the second cleaning agent interface 701b can be connected to the sedimentation tank 701a via the second connecting pipe 701e. The first cleaning agent in the lower tank 300 can flow to the sedimentation tank 701a through the second connecting pipe 701e under gravity to settle and form the second cleaning agent. The second high-pressure pump 701d can be installed on the second connecting pipe 701e. For example, the waste liquid transfer structure 701 may also include: a second flow limiter 701f installed on the second connecting pipe 701e and located between the second high-pressure pump 701d and the second cleaning agent interface 701b. The second flow limiter 701f is electrically connected to the control component and can be used to adjust the pressure of the second cleaning agent in the second pipe 701c by adjusting the flow rate of the second cleaning agent passing through the second connecting pipe 701e.

[0081] In this application, as Figure 14 As shown, the waste liquid transfer structure 701 may further include a second switching valve 701g installed on the second cleaning agent port 701b, which can be used to control the opening and closing of the second cleaning agent port 701b. For example, the second switching valve 701g can be a manual valve.

[0082] Optional, please refer to Figure 15 , Figure 15 This is a partial structural schematic diagram of another lithium battery mixer cleaning device provided in this application embodiment. The lithium battery mixer cleaning device may further include: a second connecting valve 900 and a waste liquid tank 1000. The second connecting valve 900 is located at the drain port c2 of the first connecting valve 600, and the second connecting valve 900 may have a waste liquid interface k1 and an outlet interface k2. The waste liquid tank 1000 is connected to the waste liquid interface k1 of the second connecting valve 900, and the sedimentation tank 701a is connected to the outlet interface k2. After the cleaning agent is recycled, it can be stored in the waste liquid tank 1000. For example, the waste liquid tank 1000 and the waste liquid interface k1 of the second connecting valve 900 may be connected by a hose, and the sedimentation tank 701a and the outlet interface k2 of the second connecting valve 900 may be connected by a hose. It should be noted that the second connecting valve 900 may be a three-way valve electrically connected to the control component. For example, during the initial cleaning stage, the slurry mixing assembly 400 rotates at a low speed in the lower tank. The cleaning agent sprayed by the spray assembly 500 can fully wet the slurry residue on the parts to be cleaned within a certain time. At the same time, the waste liquid interface k1 of the second connecting valve 900 is opened for a certain period of time, so that the cleaning agent mixed with a lot of slurry can be discharged directly from the waste liquid interface k1 of the second connecting valve 900 to the lower tank 300, thereby ensuring good cleanliness when the cleaning agent rinses the parts to be cleaned later. Afterwards, the waste liquid interface k1 of the second connecting valve 900 can be closed, and the slurry mixing assembly 400 continues to rotate at a low speed in the lower tank 300. The spray assembly 500 continues to spray cleaning agent into the lower tank 300. After the cleaning agent accumulated in the lower tank 300 reaches a certain amount, the control assembly 800 controls the slurry mixing assembly 400 to rotate at high speed, and after rotating at high speed for a certain period of time, the cleaning agent is discharged into the waste liquid tank 1000.

[0083] It should be noted that, in other possible implementations, a waste liquid discharge port and a control switch connected to the waste liquid discharge port (not shown in the figure) can also be provided on the sedimentation tank k2. In this way, after the cleaning agent in the sedimentation tank 701a is recycled, the waste liquid is discharged from the sedimentation tank into the waste liquid storage container by opening the waste liquid discharge port through the control switch.

[0084] In the embodiments of this application, such as Figure 10As shown, the side wall of the lower tank 300 may have a cavity k3. At least a portion of the first pipe 501b can be installed within the cavity k3 of the side wall of the lower tank 300, and at least a portion of the second pipe 701c can be installed within the cavity k3 of the side wall of the lower tank 300. In this case, by installing both the first pipe 501b and the second pipe 701c within the cavity k3 of the side wall of the lower tank 300, the integration level of the lithium battery mixer cleaning equipment can be improved, and the safety performance of the lithium battery mixer cleaning equipment can be increased.

[0085] Optional, please refer to Figure 14 and Figure 16 , Figure 16 This is one embodiment provided in this application. With the upper tank 200 and lower tank 300 in the open state, the lithium battery mixer cleaning equipment may further include: a transparent protective bag 1100, a high-pressure cleaning gun 1200, a third cleaning agent inlet 1300, and a third pipeline (not shown in the figure). The transparent protective bag 1100 may have two openings k4 arranged opposite each other. The transparent protective bag 1100 can be detachably connected to the opening a1 of the upper tank 200 through one opening k4, and the other opening k4 can be located inside the lower tank 300. The third cleaning agent inlet 1300 can be installed on the side wall of the lower tank 300. The third pipeline and the high-pressure cleaning gun 1200 can both be located inside the transparent protective bag 1100. One end of the third pipeline can be connected to the inlet of the high-pressure cleaning gun 1200, and the other end of the third pipeline can be connected to one end of the third cleaning agent inlet 1300. The other end of the third cleaning agent inlet 1300 is connected to the storage tank 501c through a fourth pipeline (not shown in the figure). In this scenario, after the control component completes the automatic cleaning process of the lithium battery mixer cleaning equipment, the upper tank 200 and lower tank 300 are separated, allowing the operator to observe the cleanliness of the lithium battery mixer. If any parts of the lithium battery mixer are not thoroughly cleaned, the operator can manually install the transparent protective bag 1100 and use the high-pressure cleaning gun 1200 to clean the uncleaned areas with the first cleaning agent in the storage tank 501c, ultimately ensuring the cleanliness of the lithium battery mixer. Furthermore, the transparent protective bag 1100 facilitates real-time observation by the operator, prevents cleaning agent splashing, provides good safety, and is easy to use. In this application, the transparent protective bag 1100 may have an elastic ring 1101 installed at the opening k4. The transparent protective bag 1100 is secured to the opening a1 of the upper tank 200 by this elastic ring 1101. When not in use, the transparent protective bag 1100 can be removed by separating the elastic ring 1101 from the opening a1 of the upper tank 200.

[0086] For example, such as Figure 14As shown, the lithium battery mixer cleaning equipment may further include a third switching valve 1400 disposed at the third cleaning agent inlet 1300, which can be used to control the opening and closing of the third cleaning agent inlet 1300. For example, the third switching valve 1400 may be a manual valve.

[0087] In this embodiment, the transparent protective bag 1100 may have a bionic hand kit 1102 on its side. This allows the operator to reach into the cavity of the bionic hand kit 1102 to grasp the high-pressure cleaning gun, completely isolating the operator from the transparent protective bag 1100. This further prevents cleaning agent from splashing onto the operator's hands and facilitates the operation of the high-pressure cleaning gun.

[0088] Optional, such as Figure 12 As shown, the lower tub 300 may have a drying hot air inlet 301 on its side wall, which can be used to connect a drying device. For example, the lithium battery mixer cleaning equipment may further include a fourth switching valve 1500 disposed at the drying hot air inlet 301, which can be used to control the opening and closing of the drying hot air inlet 301. For example, the fourth switching valve 1500 can be a manual valve. Thus, after connecting the drying hot air inlet 301 to the drying device, opening the fourth switching valve 1500 allows the drying device to deliver hot air into the lower tub 300 and upper tub 200 through the drying hot air inlet 301, thereby drying the cleaned lithium battery mixer. It should be noted that the drying device may include a blower and a heater.

[0089] In the embodiments of this application, such as Figure 8 As shown, the side wall of the upper tank 200 may have an exhaust port 201, which can be used to connect to an exhaust gas recovery device. For example, the lithium battery mixer cleaning equipment may also include a fifth switching valve 1600 located at the exhaust port 201, which can be used to control the opening and closing of the exhaust port 201. For example, the fifth switching valve 1600 can be a manual valve. Thus, when the drying hot air interface 301 is opened, the exhaust port 201 is also opened, allowing the exhaust gas recovery device to draw out the exhaust gas generated during the drying process. It should be noted that the exhaust gas recovery device may include an exhaust fan and a collector.

[0090] In this application, as Figure 8 and Figure 14 As shown, the upper barrel 200 may also have a feeding port 202 on its side wall, which can be used to add production materials into the lower barrel 300.

[0091] This application embodiment also provides a method for using a lithium battery mixer cleaning device. This lithium battery mixer cleaning device can be the one described above. The method for using this lithium battery mixer cleaning device includes:

[0092] Step 1: With the upper and lower tanks in the closed state, the control component controls the spray component to open and spray a first cleaning agent with a preset pressure onto at least one of the inner wall of the upper tank, the inner wall of the lower tank, and the slurry mixing component.

[0093] Step 2: After the spray assembly is in the stopped working state, the control component controls the opening of the drain port of the first connecting valve and controls the opening of the waste liquid recovery assembly to spray a second cleaning agent with a preset pressure onto at least one of the inner wall of the upper tank, the inner wall of the lower tank, and the slurry mixing assembly.

[0094] It should be noted that the drain port of the first connecting valve can also be opened at the same time as the spray assembly is opened in step 1.

[0095] In summary, this application provides a method for using a lithium battery mixer cleaning device. By integrating a spray assembly, a first connecting valve, and a waste liquid recovery assembly into the lithium battery mixer, after the upper and lower tanks are in the closed state, the control assembly can control the spray assembly to open upon receiving an opening command. The spray assembly can spray a first cleaning agent with a preset pressure onto at least one of the inner walls of the upper tank, the inner walls of the lower tank, and the slurry mixing assembly. After the spray assembly sprays the first cleaning liquid for a preset cleaning time, the control assembly controls the spray assembly to stop working and simultaneously controls the opening of the drain port of the first connecting valve and the waste liquid recovery assembly. The waste liquid recovery assembly uses a second cleaning agent discharged from the drain port to spray a second cleaning agent with a preset pressure onto at least one of the inner walls of the upper tank, the inner walls of the lower tank, and the slurry mixing assembly. In this way, the lithium battery mixer cleaning equipment can automatically clean the lithium battery mixer in a closed space when the upper and lower tanks are closed, avoiding operator contact with cleaning solvents (such as NMP solvent). The cleaning efficiency and effect are both good and safe and reliable, thus ensuring lithium battery production efficiency. Furthermore, there is no need to separate the upper and lower tanks and manually scrape the cleaning parts, effectively avoiding waste liquid splashing and secondary pollution. The waste liquid after cleaning can also be recycled, reducing cleaning solvent consumption and lowering cleaning costs.
