[0042] Embodiment 1

[0043] During the production process of electrolytic copper foil, the sealing water of the copper dissolving tank 10 is used to seal the system. On the one hand, it is to prevent the harmful gas or liquid in the copper dissolving tank 10 from evaporating and leaking, causing pollution; on the other hand, it is to prevent the heat in the tank from dissipating and ensure stable operation in the copper dissolving tank 10.

[0044] Therefore, see Figure 1 As shown, the first embodiment of the present application provides a monitoring and control device 100, which can monitor the water level of the sealed water tank 200 in the copper dissolving tank 10 in real time, and adjust the water level in the sealed water tank 200 according to the water level of the sealed water tank 200.

[0045] Among them, see Figure 2 As shown, the monitoring and control device 100 includes a water level tube 110, a first monitoring unit 120 and a control unit. The water level tube 110, the first monitoring unit 120 and the control unit can effectively maintain the water level of the sealed water tank 200 at a sealed water level, thereby ensuring the sealing effect of the copper dissolving tank 10 and avoiding the situation where the copper dissolving effect is poor due to insufficient sealing water.

[0046] In the embodiment of the present application, the water level tube 110 includes a tube body 111, and the cross section of the tube body 111 is circular, but not limited thereto, and the tube body 111 may also be square, oval, etc. The water level of the tube body 111 is consistent with the water level in the sealed water tank 200, so that the water level change in the sealed water tank 200 can be obtained in real time by monitoring the water level in the tube body 111.

[0047] In the examples of this application, see Figure 2 As shown, the water level tube 110 also includes a monitored component 112 disposed inside the tube body 111. The monitored component 112 can move inside the tube body 111 following the water level changes inside the tube body 111, that is, the position of the monitored component 112 can reflect the water level in the sealed water tank 200 in real time.

[0048] The first monitoring unit 120 can monitor the position of the monitored component 112 in the pipe body 111 to obtain monitoring information and transmit the monitoring information to the control unit. The control unit compares the monitoring information with the preset water level information to determine whether the water level in the sealed water tank 200 can reach the sealing water level. If the monitoring information is less than the preset water level information, the control unit outputs a first control signal to adjust the opening of the regulating valve 420 of the water inlet pipe 400 discharged into the copper dissolving tank 10, and increase the water level discharged from the water inlet pipe 400 into the sealed water tank 200 to ensure the sealing effect; while the water inlet pipe 400 continues to inject water into the sealed water tank 200, the first monitoring unit 120 continuously monitors the position of the monitored component 112. When the position of the monitored component 112 reaches the preset position, that is, the water level in the sealed water tank 200 is the same as the preset water level, the first monitoring unit 120 transmits the monitored signal to the control unit, and the control unit compares the signal with the preset water level information. The control unit outputs a second control signal based on the comparison information, and the second control signal closes the regulating valve 420 on the water inlet pipe 400 to stop injecting water into the sealed water tank 200.

[0049] The present application scheme can monitor the water level in the sealed water tank 200 in real time through the water level tube 110 and the first monitoring unit 120. The first monitoring unit 120 can transmit the positional relationship of the monitored component 112 to the control unit. The control unit compares this positional relationship with the preset water level signal to determine whether to inject water into the sealed water tank 200, thereby controlling the water level in the sealed water tank 200 in real time, automatically replenishing the sealing water according to the actual situation, and effectively avoiding the situation of poor copper dissolving effect caused by insufficient sealing water. In addition, the present application is completely self-controlled throughout the entire process, reducing labor costs and improving production efficiency.

[0050] It is worth mentioning that the water level tube 110 can be arranged outside the sealed water tank 200 or inside the sealed water tank 200 , as long as the water level in the water level tube 110 can be kept consistent with the water level in the sealed water tank 200 .

[0051] It can be understood that when the water level pipe 110 is arranged outside the sealed water tank 200, it is necessary to connect the water level pipe 110 and the sealed water tank 200 through a connecting pipe, and the water level pipe 110 and the sealed water tank 200 are located at the same height to ensure that the water level pipe 110 and the sealed water tank 200 are at the same atmospheric pressure, thereby ensuring that the water level in the water level pipe 110 is consistent with the water level in the sealed water tank 200.

[0052] In the examples of this application, see Figure 1 or Figure 3As shown, the pipe body 111 is disposed in the sealed water tank 200 and extends in the depth direction of the sealed water tank 200 .

[0053] The tube body 111 may be perpendicular to the bottom wall of the sealed water tank 200 , or may have an angle with the bottom wall of the sealed water tank 200 , as long as the water level in the tube body 111 is kept consistent with the water level in the sealed water tank 200 .

[0054] In the examples of this application, see Figure 2 As shown, the pipe body 111 is perpendicular to the bottom wall of the sealed water tank 200 , ensuring that the water level in the pipe body 111 is consistent with the water level in the sealed water tank 200 .

[0055] In order to make the water level in the tube body 111 consistent with the water level in the sealed water tank 200, the tube body 111 is provided with a water inlet, which is arranged at the bottom wall of the tube body 111 close to the sealed water tank 200, so that the water level in the sealed water tank 200 can flow into the tube body 111.

[0056] It is understandable that by placing the tube body 111 in the sealed water tank 200 , more accurate water level information can be obtained without information difference, so that the monitoring and control device 100 can more accurately determine the water level information in the sealed water tank 200 .

[0057] In the examples of this application, see Figure 2 or Figure 4 As shown, the pipe body 111 further includes a detection port 1110, which is arranged in sequence with the water inlet in the axial direction of the pipe body 111, and the detection port 1110 is located on the side of the water inlet away from the bottom wall of the sealed water tank 200, that is, the detection port 1110 is located above the water inlet. The detection ports 1110 are opened on both sides of the axial direction of the pipe body 111, and the two detection ports 1110 are arranged opposite to each other to improve the accuracy of the first monitoring unit 120.

[0058] See also Figure 2 As shown, the detection port 1110 is arranged opposite to the first monitoring unit 120, that is, the first monitoring unit 120 is arranged opposite to the detection port 1110. The detection port 1110 can expose the monitored component 112 when the water level in the pipe body 111 reaches the preset sealing water level. The first monitoring unit 120 monitors whether the detection port 1110 exposes the monitored component 112 in real time, and transmits the monitoring information to the control unit, so as to determine whether it is necessary to inject water into the sealed water tank 200.

[0059] For example, if the first monitoring unit 120 detects that the monitored component 112 is located at the detection port 1110, it means that the water level in the sealed water tank 200 meets the preset water level, and the control unit closes the regulating valve 420 and stops injecting water into the sealed water tank 200. If the first monitoring unit 120 detects that the monitored component 112 is not located at the detection port 1110, it means that the water level in the sealed water tank 200 does not meet the preset water level, and the control unit opens the regulating valve 420 and continues to inject water into the sealed water tank 200 until the monitored component 112 is located at the detection port 1110, and then stops injecting water into the sealed water tank 200.

[0060] It is worth mentioning that the first monitoring unit 120 can use a photoelectric sensor or other types of sensors, such as an ultrasonic sensor. The monitored component 112 can use a floating ball structure, or other structures that can float on the water. The diameter of the monitored component 112 is smaller than the diameter of the pipe body 111, so that the monitored component 112 can move inside the pipe body 111. The monitored component 112 is 2-3 cm, for example, 2 cm, 2.5 cm or 3 cm.

[0061] In addition, the detection port 1110 is a long strip structure, and the height monitored by the first monitoring unit 120 is greater than the length of the detection port 1110. The position information of the monitored component 112 can be obtained at the moment when the monitored component 112 is exposed at the detection port 1110, and the monitoring is more accurate.

[0062] The height monitored by the first monitoring unit 120 is 7 to 9 cm, for example, 7 cm, 8 cm, 9 cm, etc.

[0063] In the embodiment of the present application, the outer wall height of the sealed water tank 200 is 10 cm, the inner wall height of the sealed water tank 200 is 7 cm, the water level height of the sealed water tank 200 is 6-7 cm, the height that the first monitoring unit 120 can monitor is 8 cm, and the sealing effect is best when the liquid level of the sealed water tank 200 reaches the highest point of the inner wall of the sealed water tank 200.

[0064] In the examples of this application, see Figure 4 As shown, the monitoring and control device 100 further includes a second monitoring unit 130 for monitoring whether the tank cover 300 of the copper dissolving tank 10 is opened. The second monitoring unit 130 is disposed on the inner wall of the sealed water tank 200 .

[0065] The control unit is electrically connected to the second monitoring unit 130. When the second monitoring unit 130 detects that the tank cover 300 is opened, a monitoring signal is input to the control unit, and the control unit controls the first monitoring unit 120 to be closed. At this time, the first monitoring unit 120 cannot operate. After the tank cover 300 is closed, the second monitoring unit 130 inputs a monitoring signal to the control unit, and the control unit controls the first monitoring unit 120 to operate, thereby being able to obtain the water level in the sealed water tank 200 in real time to ensure that the water level in the sealed water tank 200 can seal the copper dissolving tank 10 and ensure the copper dissolving effect.

[0066] In the examples of this application, see Figure 2 or Figure 4 As shown, the water level pipe 110 further includes a blocking cover 113 , which is disposed on the top of the pipe body 111 to prevent the monitored component 112 from rushing out from above the pipe body 111 .

[0067] The copper dissolving tank 10 includes at least two sealed water tanks 200. Adjacent sealed water tanks 200 may be interconnected or separated from each other, and the specific details are not limited. Each sealed water tank 200 is provided with a water level pipe 110, a first monitoring unit 120 and a second monitoring unit 130, so as to ensure that when the tank cover 300 is closed, the first monitoring unit 120 can monitor the water level in the sealed water tank 200 in real time, and effectively avoid the situation where the copper dissolving effect is poor due to insufficient sealing water.

[0068] It is worth mentioning that the first monitoring unit 120 and the second monitoring unit 130 in each sealed water tank 200 can be connected to the same control unit to reduce the number of control units and optimize costs.

[0069] For examples, see Figure 1 or Figure 3As shown, the copper dissolving tank 10 includes two sealed water tanks 200 and two tank covers 300 that are symmetrically arranged. The two sealed water tanks 200 are interconnected to ensure that the water levels in the two sealed water tanks 200 are the same, so as to avoid the situation where the sealing effects are different. A baffle is provided between two adjacent sealed water tanks 200, and an opening is provided on the baffle to ensure that the water levels in the two sealed water tanks 200 are consistent. Among them, a water level pipe 110, a first monitoring unit 120 and a second monitoring unit 130 are provided in both sealed water tanks 200. The first monitoring units 120 in the two sealed water tanks 200 are arranged on opposite sides of the baffle. The water level pipes 110, the first monitoring unit 120 and the second monitoring unit 130 in the two sealed water tanks 200 are symmetrically arranged relative to the baffle. The second monitoring unit 130 monitors the opening of each tank cover 300 respectively to determine the operating state of the first monitoring unit 120. Thus, by providing the corresponding water level pipe 110 , the first monitoring unit 120 and the second monitoring unit 130 in each sealed water tank 200 , the fault tolerance rate of the monitoring and control device 100 can be improved.

[0070] Understandably, see Figure 1 or Figure 3 As shown, the copper dissolving tank 10 also includes a water inlet pipeline 400 for injecting water into the sealed water tank 200. The water inlet pipeline 400 includes a main pipeline 410, a regulating valve 420 and at least two branch pipelines 430. Each branch pipeline 430 is interconnected with the main pipeline 410, and the regulating valve 420 is provided at the connection between the main pipeline 410 and the branch pipeline 430. The regulating valve 420 is electrically connected to the control unit, and can receive the control signal transmitted by the control unit to adjust its own opening to adjust the water flow on each branch pipeline 430. That is, the control unit can adjust the opening of the regulating valve 420 according to the position information of the monitored component 112 monitored by the first monitoring unit 120, so as to ensure that the water level in the sealed water tank 200 meets the sealing water level. The number of branch pipelines 430 corresponds to the number of sealed water tanks 200.

[0071] For example, the copper dissolving tank 10 includes a main pipeline 410, a regulating valve 420 and two branch pipelines 430, one end of the two branch pipelines 430 is connected to the main pipeline 410 through the regulating valve 420, and the other end is connected to the sealed water tank 200. The branch pipeline 430 adopts a semicircular structure, which is arranged around the outside of the copper dissolving tank 10.

[0072] In addition, the copper dissolving tank 10 also includes an alarm device, which is electrically connected to the first monitoring unit 120, the second monitoring unit 130 and the control unit. The alarm device can alarm when at least one of the first monitoring unit 120, the second monitoring unit 130 and the control unit fails. The alarm can be a sound alarm or other alarm methods. The alarm device can effectively avoid mistakes caused by device failures and ensure production stability.

[0073] See also Figure 1 As shown, the copper dissolving tank 10 also includes an operation panel 500, which is electrically connected to the first monitoring unit 120 and the alarm device. The operation panel 500 can present different display information according to the operating status of the first monitoring unit 120 and the alarm device, so as to timely determine the status of the monitoring and control device 100 and make timely operations.

[0074] For example, when the first monitoring unit 120 operates normally, the operation panel 500 displays a green light; when the first monitoring unit 120 stops operating, the operation panel 500 displays a yellow light; when the device fails, the operation panel 500 displays a red light.

[0075] The working principle of the monitoring and control device 100 is as follows:

[0076] When the copper dissolving tank 10 is working normally, the tank cover 300 is in a closed state, the second monitoring unit 130 sends a signal, and the first monitoring unit 120 monitors the position relationship of the monitored component 112 inside the pipe body 111 in real time. If the first monitoring unit 120 does not monitor the monitored component 112 at the detection port 1110, the control unit controls the regulating valve 420 on the water inlet pipeline 400 to open, and water is injected into the sealed water tank 200. The water level continues to rise, and the first monitoring unit 120 continues to monitor the monitored component 112. When the monitored component 112 is exposed at the detection port 1110, the first monitoring unit 120 sends a control signal to the control unit, and the control unit controls the regulating valve 420 to close and stop injecting water into the sealed water tank 200.

[0077] Embodiment 2

[0078] See also Figure 1 or Figure 3 As shown, embodiment 2 of the present application provides a copper dissolving tank 10, which includes a water inlet pipeline 400, at least two sealed water tanks 200 and a monitoring and control device 100 described arbitrarily in embodiment 1. The monitoring and control device 100 can obtain the water level in the sealed water tank 200 in real time to regulate the water level in the sealed water tank 200.

[0079] The water inlet pipeline 400 includes a main pipeline 410, a regulating valve 420 and at least two branch pipelines 430. Each branch pipeline 430 is interconnected with the main pipeline 410, and the regulating valve 420 is provided at the connection between the main pipeline 410 and the branch pipeline 430. The regulating valve 420 is electrically connected to the control unit in the monitoring and control device 100, and can receive the control signal sent by the control unit to adjust its own opening to adjust the water flow on each branch pipeline 430. That is, the control unit can adjust the opening of the regulating valve 420 according to the position information of the monitored component 112 monitored by the first monitoring unit 120, so as to ensure that the water level in the sealed water tank 200 meets the sealing water level. The number of branch pipelines 430 corresponds to the number of sealed water tanks 200.

[0080] For example, the copper dissolving tank 10 includes a main pipeline 410, a regulating valve 420 and two branch pipelines 430, one end of the two branch pipelines 430 is connected to the main pipeline 410 through the regulating valve 420, and the other end is connected to the sealing water tank 200. The branch pipeline 430 adopts a semicircular structure, which is arranged around the outside of the copper dissolving tank 10. The control unit can adjust the opening of the regulating valve 420 according to the position information of the monitored component 112 obtained by the first monitoring unit 120, so as to avoid the situation where the copper dissolving effect is poor due to insufficient sealing water.

[0081] In addition, the copper dissolving tank 10 also includes an alarm device, which is electrically connected to the first monitoring unit 120, the second monitoring unit 130 and the control unit. The alarm device can alarm when at least one of the first monitoring unit 120, the second monitoring unit 130 and the control unit fails. The alarm can be a sound alarm or other alarm methods. The alarm device can effectively avoid mistakes caused by device failures and ensure production stability.

[0082] See also Figure 1 As shown, the copper dissolving tank 10 also includes an operation panel 500, which is electrically connected to the first monitoring unit 120 and the alarm device. The operation panel 500 can present different display information according to the operating status of the first monitoring unit 120 and the alarm device, so as to timely determine the status of the monitoring and control device 100 and make timely operations.

[0083] For example, when the first monitoring unit 120 operates normally, the operation panel 500 displays a green light; when the first monitoring unit 120 stops operating, the operation panel 500 displays a yellow light; when the device fails, the operation panel 500 displays a red light.
