Description

Technical Field

[0001] This utility model relates to the field of electroforming foil technology, and in particular to an automatic acid replenishment and blending system. Background Technology

[0002] In existing electrolytic foil production, acid needs to be replenished to the production line continuously. This is typically done using a mixing tank and a replenishment tank. The acid is mixed in the mixing tank and then transferred to the replenishment tank for use. This process presents the following problems:

[0003] The above-mentioned blending and transfer are usually carried out manually, with each step started and stopped manually. This is inefficient, and when the number of production lines increases, it is easy for errors to occur when multiple blending systems are operated manually at the same time, which will affect the production quality of the electrolytic foil.

[0020] The embodiments will be further described below with reference to the accompanying drawings.

[0021] like Figure 1 As shown in the preferred embodiment 1, the automatic acid replenishment blending system includes several blending subsystems 4. Each blending subsystem 4 is electrically connected in parallel to the PLC control cabinet 1. Each blending subsystem 4 includes a blending module 5 and a replenishment module 6 connected in sequence. The PLC control cabinet 1 is equipped with a touch screen 2 and a control switch 3 on its outside. The touch screen 2 and the control switch 3 are linked and coordinated with each blending subsystem 4 through the PLC control cabinet 1.

[0022] Each of the blending modules 5 includes a blending tank 51. The water inlet of each blending tank 51 is connected to an external water source through a water inlet valve 53. The acid inlet of each blending tank 51 is connected to an external acid source through an acid inlet valve 54. Each blending tank 51 is equipped with a stirring device 52, a pH online monitoring instrument 55, and a first liquid level sensor 56. The liquid outlet of each blending tank 51 is equipped with a first liquid outlet valve 57.

[0023] The first liquid level sensor 56 is linked with the corresponding stirring device 52 and water inlet valve 53 through the PLC control cabinet 1. The pH online monitoring instrument 55 is linked with the corresponding stirring device 52 and acid inlet valve 54 through the PLC control cabinet 1. During the production process, automatic mixing is carried out in the mixing tank 51 of the mixing module 5. When the first liquid level sensor 56 detects that the acid level is lower than the minimum setting, the first liquid outlet valve 57 is closed through the PLC control cabinet 1, the water inlet valve 53 is started for automatic water replenishment, and the stirring device 52 is started for stirring. When the first liquid level sensor 56 detects that the acid level exceeds the maximum setting value, the water inlet valve 53 is closed through the PLC control cabinet 1 to stop water intake. At this time, the acid inlet valve 54 is opened for mixing. The pH is monitored in real time through the pH online monitoring instrument 55 until the pH reaches the set value. Then, the acid inlet valve 54 is closed through the PLC control cabinet 1 to stop acid intake and the stirring device 52 is stopped, ready for use.

[0024] All the replenishment modules 6 include a replenishment tank 61. The inlet of the replenishment tank 61 is connected to the outlet of the corresponding first delivery pump 62. The inlet of the first delivery pump 62 is connected to the corresponding first outlet valve 57. The replenishment tank 61 is equipped with a second liquid level sensor 63.

[0025] The second liquid level sensor 63 is linked with the corresponding first delivery pump 62 and first outlet valve 57 through the PLC control cabinet 1.

[0026] The outlet of the replenishment tank 61 is connected to the acid inlet of the electrolytic foil production line via the second outlet valve 64 and the second delivery pump 65. During production, the replenishment tank 61 of the replenishment module 6 continuously supplies acid to the production line via the second outlet valve 64 and the second delivery pump 65. When the second liquid level sensor 63 detects that the acid level is lower than the minimum setting, the first delivery pump 62 and the first outlet valve 57 are started through the PLC control cabinet 1 for automatic replenishment until the second liquid level sensor 63 detects that the acid level exceeds the maximum setting value. Then, the first delivery pump 62 and the first outlet valve 57 are shut down through the PLC control cabinet 1 to stop automatic replenishment.

[0027] The water inlet valve 53, acid inlet valve 54, first liquid outlet valve 57, and second liquid outlet valve 64 are all electric valves, ensuring the realization of rotation control.

[0028] As a preferred embodiment 2, the pH online monitor 55 can be an MDC-P1 / P2 pH online monitor, the first liquid level sensor 56 and the second liquid level sensor 63 can be PCM266 liquid level sensors; the PLC control cabinet 1 can be an existing touch screen control cabinet.

[0029] As a preferred embodiment 3, after the replenishment tank 61 completes replenishment, the liquid level in the mixing tank 51 is just below the minimum set value, ensuring that the mixing tank 51 can automatically remix after each replenishment, thus ensuring the smooth progress of the next replenishment.

[0030] The working principle of this utility model:

[0031] The PLC control cabinet 1 enables each blending subsystem 4 to achieve independent self-control, ensuring the acid supply for each electrolytic foil production line. Each blending subsystem 4 can automatically replenish and blend, improving work efficiency and ensuring production needs.

[0032] During the production process, the replenishment tank 61 of the replenishment module 6 continuously supplies acid to the production line through the second outlet valve 64 and the second delivery pump 65;

[0033] When the second liquid level sensor 63 detects that the acid level is lower than the minimum setting, the first delivery pump 62 and the first outlet valve 57 are started through the PLC control cabinet 1 to automatically replenish the acid. When the second liquid level sensor 63 detects that the acid level exceeds the maximum setting value, the first delivery pump 62 and the first outlet valve 57 are turned off through the PLC control cabinet 1 to stop the automatic replenishment.

[0034] During the production process, automatic blending is carried out in the blending tank 51 of the blending module 5;

[0035] When the first liquid level sensor 56 detects that the acid level is lower than the minimum setting, the first outlet valve 57 is closed via PLC control cabinet 1, the inlet valve 53 is started for automatic water replenishment, and the stirring device 52 is started for stirring. When the first liquid level sensor 56 detects that the acid level exceeds the maximum setting value, the inlet valve 53 is closed via PLC control cabinet 1 to stop water intake. At this time, the acid inlet valve 54 is opened for mixing. The pH is monitored in real time via pH online monitor 55 until the pH online monitor 55 detects that the pH has reached the set value. Then, the acid inlet valve 54 is closed via PLC control cabinet 1 to stop acid intake, and the stirring device 52 is stopped, waiting for use to ensure that there is always liquid available for replenishment.
