[0020] Some embodiments of this application are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of this application and are not intended to limit the scope of protection of this application.

[0021] Currently, when cleaning electrolyte tanks, the corresponding pipelines are manually connected to the liquid phase port, spray port, gas phase port, and recovery port of the electrolyte tank. Due to the sealed and invisible nature of the electrolyte tank, the staff cannot know the cleaning status of the electrolyte tank and the specific situation of other cleaning steps in a timely manner. As a result, the cleaning of the electrolyte tank usually fails to meet the cleaning requirements, and the cleaning time and cleaning efficiency cannot be guaranteed.

[0022] Therefore, this application creatively proposes an electrolyte tank cleaning device, which includes a frame, a weighing platform, a solvent tank, a liquid phase pipeline, a spray pipeline, a gas phase pipeline, and a recovery pipeline. A liquid flow switch is installed on the liquid phase pipeline, and pressure sensors are respectively installed on the recovery pipeline and the solvent tank. Quick-connect couplings allow for rapid connection between the electrolyte tank and corresponding components. During the cleaning process, if the connection between the liquid phase pipeline and the liquid phase port is unstable or if the solvent tank is contaminated, [further issues may occur]. The quick-connect coupling allows for rapid connection between the electrolyte tank and corresponding components. When solvent flows through the liquid phase pipeline, if the connection between the liquid phase pipeline and the liquid phase inlet is not tight, or if there is insufficient solvent in the solvent tank, the liquid flow switch will not meet the opening conditions and will send a feedback signal to the alert component. This allows personnel to resolve the issue promptly, ensuring effective cleaning of the liquid phase pipeline within the electrolyte tank and preventing waste of cleaning solvent. Simultaneously, the pressure sensor at the solvent tank can promptly obtain the solvent pressure flowing into the spray pipeline. When the solvent pressure falls below the second pressure value, it will send a feedback signal to the alert component, allowing personnel or the cleaning device to adjust the solvent flow into the spray pipeline in a timely manner. Pressure is applied to ensure the solvent pressure entering the spray nozzle meets operational requirements, guaranteeing effective spray cleaning of the electrolyte tank's inner wall. After cleaning the electrolyte tank with solvent, inert gas is introduced into the gas phase port through the gas phase pipeline to expel the solvent from the electrolyte tank. When the weighing platform detects that the mass of the electrolyte tank fluctuates relatively little for a period of time, it is determined that the solvent in the electrolyte tank has been emptied. Then, a blower is used to quickly remove the gas from the electrolyte tank, achieving rapid depressurization. When the pressure sensor on the recovery pipeline detects that the pressure inside the electrolyte tank has reached the first pressure value, the blower is shut off, thereby shortening the depressurization time and improving the overall cleaning efficiency of the electrolyte tank.

[0023] The present application will be described in detail below through specific embodiments.

[0024] Reference Figures 1 to 5As shown in the figure, this application embodiment provides an electrolyte tank 3 cleaning device. The cleaning device includes a frame 1, a weighing platform 2, a solvent storage tank assembly 4, a liquid phase pipeline 5, a spray pipeline 6, a gas phase pipeline 7, a recovery pipeline 8, and a reminder component. The solvent storage tank assembly 4 has at least one solvent tank 41. The weighing platform 2 is installed on the frame 1 and is used to place the electrolyte tank 3. The liquid phase pipeline 5, the spray pipeline 6, and the gas phase pipeline 7 are all installed on the frame 1, and both ends of the three have quick-connect couplings. One end of the liquid phase pipeline 5 and the spray pipeline 6 are used to connect to the solvent tank 41, and the other end of the liquid phase pipeline 5 is used to connect to the liquid phase port 31 of the electrolyte tank 3. The other end of the spray pipeline 6 is used to connect to the spray port 32 of the electrolyte tank 3. One end of the gas phase pipeline 7 is used to connect to a fan 71 or an air source, and the other end is used to connect to the gas phase port 33 of the electrolyte tank 3. A liquid flow switch 51 is installed on the liquid phase pipeline 5. The liquid flow switch 51 is used to send a feedback signal when the solvent flow rate in the liquid phase pipeline 5 is lower than the set flow rate value. Pressure sensors are installed on both the recovery pipeline 8 and the solvent tank 41. The pressure sensor on the recovery pipeline 8 is used to send feedback on the fluid pressure value flowing out of the electrolyte tank 3, and sends a corresponding feedback signal when the fluid pressure value released from the electrolyte tank 3 reaches the first pressure value. The pressure sensor on the solvent tank 41 is used to send a feedback signal when the solvent flowing out of the solvent tank 41 is lower than the second pressure value. The reminder component is communicatively connected to the liquid flow switch 51 and all pressure sensors.

[0025] It is understood that the liquid phase pipeline 5, spray pipeline 6, gas phase pipeline 7, and recovery pipeline 8 can be made of flexible tubing, or a combination of rigid tubing and flexible tubing. Of course, in some extreme cases, they can be made of only rigid tubing. In this embodiment, to facilitate quick connection of the above pipelines with other components, at least a portion of the above pipelines is made of flexible tubing, such as setting the ends of the liquid phase pipeline 5 and spray pipeline 6 as flexible tubing to allow for flexible connection with other pipelines.

[0026] In addition, the electrolyte tank 3 is generally equipped with components such as a spray ball. The spray ball is connected to the spray nozzle 32 so that the solvent can enter the spray ball through the spray nozzle 32, thereby thoroughly cleaning the inner wall of the electrolyte tank 3 and the outer wall of the liquid phase tube. The specific structure is existing technology and will not be described in detail here. In this embodiment, the pressure sensor at the recovery pipeline 8 is a pressure transmitter 81.

[0027] Specifically, when preparing to clean the electrolyte tank 3, the electrolyte tank 3 to be cleaned is first placed on the weighing platform 2. Then, using the quick-connect fittings of the corresponding pipelines, the liquid phase port 31 and spray port 32 of the electrolyte tank 3 are connected to the solvent tank 41, the recovery port 34 is connected to the recovery pipeline 8, and the gas phase port 33 is connected to the gas source. Then, cleaning solvent is introduced into the liquid phase port 31 through the liquid phase pipeline 5 to clean the liquid phase tube inside the electrolyte tank 3. When the flow rate in the liquid phase pipeline 5 does not reach the set flow rate value, the liquid flow switch 51 cannot open and feeds back the signal to the reminder component, so that the staff can adjust the connection status between the liquid phase pipeline 5 and the liquid phase port 31 in time to ensure the cleaning of the inner wall of the liquid phase tube and avoid wasting solvent. At the same time, cleaning solvent is introduced into the spray port 32 through the spray pipeline 6 to clean the inner wall of the electrolyte tank 3 and the outer wall of the liquid phase tube. The pressure sensor on the solvent tank 41 can detect the flow into the spray port in time. When the solvent pressure in the spray pipe 6 is lower than the second pressure value, a feedback signal is sent to the reminder component. The reminder component issues a reminder, enabling the cleaning device and / or workers to adjust the solvent pressure in a timely manner to ensure the pressure of the solvent entering the spray nozzle 32, thereby ensuring the cleaning effect on the inner wall of the electrolyte tank 3 and the outer wall of the liquid phase pipe. According to the cleaning requirements, solvent is continuously introduced into the electrolyte tank 3 for a period of time. Then, the passage between the solvent tank 41 and the electrolyte tank 3 is cut off. If the test data of the weighing platform 2 remains stable for a period of time, it is determined that the preliminary cleaning of the electrolyte tank 3 is completed. Then, the gas source and gas phase pipeline 7 are connected, as are the recovery port 34 and recovery pipeline 8. Inert gas is introduced into the electrolyte tank 3 through the gas phase port 33 to compress the solvent in the electrolyte tank 3. At the same time, the solvent tank 41 can be depressurized to better discharge the solvent back to the solvent tank 41 through the recovery pipeline 8. The pressure sensor installed on the recovery pipeline 8 can obtain the fluid pressure at the recovery port 34 of the electrolyte tank 3 in a timely manner so as to adjust the pressure of the inert gas in time, thereby better adjusting the time for discharging the solvent back to the solvent tank 41 and improving the solvent discharge efficiency. When the test data of the weighing platform 2 maintains small fluctuations within a certain period of time, and / or when the discharge time reaches a set value, it is determined that the solvent in the electrolyte tank 3 has been emptied. After the solvent in the electrolyte tank 3 is emptied, the gas port 33 is connected to the blower 71, and the blower 71 is started to draw away the gas in the electrolyte tank 3, so that the gas pressure in the electrolyte tank 3 can drop rapidly. At the same time, the pressure sensor on the recovery pipeline 8 is used to detect the gas pressure at the recovery pipeline 8. When the gas pressure in the recovery pipeline 8 reaches the second pressure value, the pressure sensor sends a feedback signal and transmits the signal to the reminder component. The reminder component issues a reminder, and the cleaning process or the staff can shut off the blower 71 in time, thereby quickly depressurizing the electrolyte tank 3. Finally, all pipelines are disconnected from the electrolyte tank 3, completing the cleaning of the electrolyte tank 3.

[0028] In some examples, a pressure relief valve is installed on the gas phase line 7. By coordinating the pressure relief valve with the blower 71, the pressure in the electrolyte tank 3 can be accurately maintained at the first pressure value while rapidly releasing pressure.

[0029] It should be noted that when the cleaning device only uses the fan 71 to depressurize the electrolyte tank 3, the condition for the fan 71 to stop working is that the air pressure in the electrolyte tank 3 reaches the first pressure value; when the cleaning device uses the fan 71 and the pressure relief valve to depressurize, the condition for the fan 71 to stop working is that the air pressure in the electrolyte tank 3 reaches the preset pressure value, and the preset pressure value is slightly higher than the first pressure value.

[0030] Specifically, after the solvent in the electrolyte tank 3 is drained, the gas in the electrolyte tank 3 is first quickly extracted by the blower 71 to achieve rapid depressurization of the electrolyte tank 3. When the pressure sensor on the recovery pipeline 8 detects that the pressure has reached the preset pressure value, the blower 71 is turned off. Then, the pressure relief valve is used to precisely depressurize the electrolyte tank 3 to achieve rapid and accurate depressurization.

[0031] The pressure relief valve can operate simultaneously with the fan 71 and continue to depressurize the electrolyte tank 3 after the fan 71 stops operating; alternatively, the pressure relief valve can start depressurizing the electrolyte tank 3 after the fan 71 stops operating. In this embodiment, the pressure relief valve operates simultaneously with the fan 71 and continues until the depressurization is complete.

[0032] In some examples, refer to Figure 1 As shown, the cleaning device for electrolyte tank 3 also includes a squeezing pipeline 72, one end of which is connected to solvent tank 41, and the other end is used to connect to a gas source to squeeze and transport the solvent in solvent tank 41 to liquid phase pipeline 5 and / or spray pipeline 6.

[0033] In this embodiment, the gas supplied by the gas source is generally an inert gas with a certain pressure to avoid contaminating the solvent.

[0034] It should be noted that many manufacturers typically use pumps or similar components to transport solvents. Impurities carried in the solvent can wear down the pump's internal structure, and the solvent may also corrode it, leading to a significant decrease in the pump's transport performance and even solvent blockage. However, in this application, inert gas is supplied to the solvent tank 41 via the extrusion pipeline 72 to transport the solvent to the appropriate pipeline. This not only avoids the problem of component wear but also significantly reduces the economic cost of solvent transport.

[0035] In some examples, refer to Figure 1 and Figure 2As shown, the solvent storage tank assembly 4 includes at least two solvent tanks 41; the liquid phase pipeline 5 includes a main pipe 52 equipped with a first valve 521, one end of the main pipe 52 is used to connect to the liquid phase port 31, and the other end branches into at least two branch pipes 53, each branch pipe 53 is equipped with a second valve 531, and each branch pipe 53 is independently connected to at least one solvent tank 41.

[0036] It should be noted that when actually cleaning the electrolyte tank 3, the number of solvent tanks 41 can be set according to the cleaning requirements. For example, if three cleanings are required, the number of solvent tanks 41 can be set to three, with one solvent tank 41 used for each cleaning. Alternatively, in some cases, different specifications (such as concentration differences) of solvent need to be used for each cleaning, in which case only one solvent tank 41 is used for each cleaning. Of course, in some examples, multiple solvent tanks 41 can be used in one cleaning, that is, multiple solvent tanks 41 simultaneously supply solvent to the liquid phase pipeline 5. In this embodiment, only one solvent tank 41 is used each time the electrolyte tank 3 is cleaned.

[0037] Specifically, when cleaning the electrolyte tank 3, first open the first valve 521, and then open the second valve 531 on the corresponding branch pipe 53 as needed, so that the solvent in the corresponding solvent tank 41 flows into the corresponding branch pipe 53, thereby cleaning the inner wall of the electrolyte tank 3.

[0038] Furthermore, in some examples, refer to Figure 1 As shown, each solvent tank 41 is equipped with a sampling port 411, and each branch pipe 53 branches off with a waste liquid pipe 54. All waste liquid pipes 54 are connected to the waste liquid tank 541.

[0039] It is understandable that the solvent in solvent tank 41 is usually used multiple times, so the solvent in solvent tank 41 needs to be tested after a certain period of time to ensure the cleaning effect of electrolyte tank 3.

[0040] Each sampling port 411 is equipped with a valve. By adjusting the valve opening, the outflow of solvent is controlled, facilitating solvent sample acquisition while preventing solvent leakage and environmental pollution. Furthermore, each waste liquid pipe 54 is equipped with a valve to facilitate the quick and easy transfer of waste solvent from solvent tank 41 to waste liquid tank 541 when solvent sample results fail to meet standards.

[0041] In addition, the electrolyte pipe cleaning device also includes a supply line 73, which is individually connected to each solvent tank 41 to deliver fresh solvent to the corresponding solvent tank 41. The pipe section between the supply line 73 and the solvent tank 41 is equipped with a valve.

[0042] In some examples, the solvent storage tank assembly 4 includes a movable mounting bracket 9 on which all solvent tanks 41 are mounted, and the mounting bracket 9 is located on one side of the frame 1. The bottom of the mounting bracket 9 is equipped with self-locking casters, allowing for quick adjustment of the distance between the solvent tanks 41 and the frame 1 by pushing the mounting bracket 9 in some cases, such as when no solvent is stored in the solvent tanks 41.

[0043] Furthermore, in some examples, refer to Figures 2 to 4 As shown, a moving platform 11 is provided below the frame 1, and a weighing platform 2 is installed on the moving part of the moving platform 11, allowing the weighing platform 2 to move closer to or further away from the mounting bracket 9. The distance between the electrolyte tank 3 and the mounting bracket 9 can be flexibly adjusted by the operation of the moving platform 11, facilitating the pipeline connection between the solvent tank 41 and the electrolyte tank 3; it also facilitates docking with the preceding process. The moving platform 11 can be a conveyor belt capable of forward and reverse transport, or other moving structures capable of smoothly transporting the electrolyte tank 3.

[0044] In some examples, refer to Figure 2 , Figure 4 and Figure 5 As shown, the liquid phase pipeline 5, spray pipeline 6, and gas phase pipeline 7 are all installed on the top of the frame 1. A photoelectric sensor 12 is installed below each of their respective connection ports, and the photoelectric sensor 12 is used to detect the position and orientation of the corresponding connection port. By placing the liquid phase pipeline 5, spray pipeline 6, and gas phase pipeline 7 on the top of the frame 1, the horizontal area occupied by the pipelines can be reduced, while avoiding external interference with the pipelines. Furthermore, to facilitate the connection between each pipeline and its corresponding components, the ends of each pipeline are generally made into flexible hoses. When the pipelines are not connected to the outside, the flexible hoses are usually rolled up, and at this time, there is no obstruction above the corresponding photoelectric sensor 12. When the flexible hose at the end of each pipeline is unrolled, the corresponding photoelectric sensor 12 will detect an obstruction above, initially determining that the end of that pipeline is connected to the outside.

[0045] It should be noted that, for ease of connection, the ends of the liquid phase pipeline 5, spray pipeline 6, and gas phase pipeline 7 are generally composed of flexible hoses, and the ends of the flexible hoses are quick-connect fittings. In this embodiment, the connection end of each pipeline generally refers to part or all of the quick-connect fittings. When both ends of each pipeline are not connected to the outside, they are generally installed in a coiled state on the top of the frame 1. At this time, the photoelectric sensor 12 is located below the corresponding pipeline. When each pipeline is connected to the outside, the position between the photoelectric sensor 12 and the corresponding pipeline will change, that is, the photoelectric sensor 12 is used to detect the positional changes of the connection ports of each pipeline.

[0046] In some examples, refer to Figure 1As shown, the liquid phase pipeline 5 and the spray pipeline 6 converge at one end and are connected to an inlet pipe 61, which is connected to the solvent tank 41. The inlet pipe 61 facilitates the centralized supply of solvent to the liquid phase port 31 and the spray port 32.

[0047] In some examples, refer to Figure 1 As shown, a residual pressure pipeline 82 branches off from the recovery pipeline 8. The residual pressure pipeline 82 is equipped with a valve and connects to the residual liquid recovery container. Before cleaning the electrolyte tank 3, the valve on the residual pressure pipeline 82 is opened, and the gas phase port 33 is connected to the gas source. Inert gas is then introduced into the electrolyte tank 3 to discharge the residual electrolyte liquid. This improves the cleaning efficiency of the electrolyte tank 3 and reduces solvent contamination, thereby increasing the number of times the solvent can be used.

[0048] In some examples, refer to Figure 2 As shown, an operating platform 13 is provided on one side of the frame 1, and a controller 14 is provided on the operating platform 13. The operation platform 13 and the controller 14 facilitate the staff to adjust the working status of the cleaning device in a timely manner.

[0049] In some examples, the alerting component includes at least three alarm elements: one communication connection to the liquid flow switch 51, and the rest connected to the respective pressure sensors. By setting individual alarm elements, it is possible to effectively distinguish which components in the cleaning device are experiencing problems.

[0050] The reminder component can also consist of only one alarm element, such as setting the alarm element as an alarm light, and then transmitting specific fault information through coding rules, such as light flashing patterns or color changes. For example, two slow flashes of the alarm light indicate that the connection between the liquid phase pipeline 5 and the liquid phase port 31 is not tight, and three fast flashes of the alarm light indicate that the pressure inside the electrolyte tank 3 has reached the first pressure value.
