[0040] like Figure 1 , Figure 2 and Figure 3 As shown, an acid pickling solution concentration proportioning component for an aluminum single-panel pickling equipment includes: a workbench 1 and multiple raw solution tanks 3 disposed on the workbench 1; a supply pipe 4 connected at one end to the raw solution tank 3; a rotating body 7 rotatably disposed in the workbench 1; a delivery pipe 8 connected at one end to the rotating body 7, wherein the supply pipe 4 forms a mating interface at its end away from the raw solution tank 3, and all mating interfaces of the supply pipes 4 are located on the rotation trajectory of the delivery pipes 8; by rotating the rotating body 7, the delivery pipes 8 can be driven to connect with the mating interface of any one of the supply pipes 4 to form a delivery channel for conveying the raw solution; a metering pump 9 connected to the delivery channel; and a first drive structure for driving the rotating body 7 to rotate.

[0041] The above technical solution can improve the efficiency of pickling solution preparation. In use, first, fill each stock solution tank 3 with the required stock solution for pickling solution preparation, ensuring the supply pipe 4 and delivery pipe 8 are unobstructed. Place the container at the outlet of the metering pump 9, start the first drive structure to rotate the rotating body 7, which in turn drives the delivery pipe 8 on the surface of the rotating body 7 to connect with the interface of one of the supply pipes 4. Then, start the metering pump 9, and the stock solution is drawn from the stock solution tank 3 through the supply pipe 4, delivery pipe 8, and metering pump 9 into the container until the required amount of stock solution is reached. The metering pump 9 then stops pumping, and the first drive structure is started to continue rotating the rotating body 7 until the delivery pipe 8 connects with the interface of the next supply pipe 4, continuing to draw the next stock solution. Through these steps, all stock solutions are drawn into the container according to the required amount, completing the preparation process with high efficiency.

[0042] like Figure 1 and Figure 2 As shown, in this embodiment, a first placement plate 2 for placing the original liquid tank 3 is provided on one side of the workbench 1;

[0043] The above technical solution allows for convenient and uniform placement of the raw material tank 3.

[0044] like Figure 2 and Figure 3 As shown, in this embodiment, a support 5 is provided in the workbench 1, and a frame 6 is connected to the support 5. The frame 6 is rotatably connected to the rotating body 7. The interfaces of all the liquid supply pipes 4 are located on the surface of the same virtual cylinder. The axis of the virtual cylinder coincides with the axis of rotation of the rotating body 7. The rotating body 7 has a sealing surface for blocking the interfaces of the liquid supply pipes 4.

[0045] like Figure 4 As shown, in this embodiment, the first drive structure includes: a driven gear 17 fixedly connected to the rotating body 7; a motor frame 18 connected to the bracket 5 at one end; a motor 19 connected to the motor frame 18; and a drive gear 20 connected to the output shaft of the motor 19, wherein the drive gear 20 meshes with the driven gear 17.

[0046] The above technical solution ensures that the rotating body 7 can rotate. When in use, the motor 19 is started so that its output shaft drives the drive gear 20 to rotate. The drive gear 20 drives the driven gear 17 to rotate. The driven gear 17 drives the rotating body 7 connected to it to rotate relative to the frame 6. This causes the liquid delivery pipe 8 connected to the rotating body 7 to align with or completely offset the interface of the liquid supply pipe 4, thereby realizing the switching of the extraction of raw liquid.

[0047] like Figure 5As shown, in this embodiment, the proportioning component further includes: an outer sleeve 14 connected to the rotating body 7 at one end, the outer sleeve 14 being connected to the liquid delivery pipe 8; an inner sleeve 15 slidably connected to the outer sleeve 14, the inner sleeve 15 being plugged into and unplugged from the interface of the liquid supply pipe 4; and a second driving structure for driving the inner sleeve 15 to extend or retract relative to the outer sleeve 14, thereby allowing the inner sleeve 15 to be plugged into or detached from the interface; specifically, the second driving structure is an electric telescopic rod 16 connected to the base and the rotating body 7, the telescopic end of the electric telescopic rod 16 being fixedly connected to the inner sleeve 15.

[0048] The above technical solution can prevent leakage of the raw liquid during transportation. In use, after the interface of the liquid delivery pipe 8 and the liquid supply pipe 4 are aligned, the electric telescopic rod 16 is activated to drive the inner sleeve 15 to extend outward, so that the inner sleeve 15 is fitted onto the interface surface of the liquid supply pipe 4 to prevent leakage of the raw liquid during transportation. In order to improve the sealing performance, a sealing ring can be set in the inner sleeve 15, so that the interface of the liquid supply pipe 4 can squeeze the sealing ring, causing the sealing ring to deform and fill the gap between the interface of the liquid supply pipe 4 and the inner wall of the inner sleeve 15, thereby further improving the sealing performance.

[0049] like Figure 2 and Figure 4 As shown, in this embodiment, the proportioning component further includes: a liquid outlet pipe 10, which is located at the end of the metering pump 9 away from the liquid delivery pipe 8; a funnel 11 with a through groove 12 at one end, one end of the liquid outlet pipe 10 is inserted into the through groove 12, and one end of the funnel 11 is connected to a drain pipe 13. The liquid supply pipe 4, inner sleeve 15, outer sleeve 14, liquid delivery pipe 8, liquid outlet pipe 10, funnel 11 and drain pipe 13 form a conveying channel.

[0050] The above technical solution can conveniently discharge the raw liquid. When in use, after the raw liquid is drawn into the outlet pipe 10 by the metering pump 9, the raw liquid will enter the funnel 11 through the channel 12. Under the action of gravity, the raw liquid enters the drain pipe 13 from the funnel 11 and is discharged into the container through the drain pipe 13.

[0051] like Figure 1 and Figure 2 As shown, in this embodiment, the workbench 1 is provided with a second placement plate 22, the upper end of the second placement plate 22 is provided with an acid pickling solution tank 21, and the lower end of the second placement plate 22 in the workbench 1 is provided with a storage cavity 23.

[0052] The above technical solution allows the pickling solution tank 21 to be used as a container to receive the raw solution. When in use, the pickling solution tank 21 is placed directly below the drain pipe 13, ensuring that the inlet of the pickling solution tank 21 is aligned with the drain pipe 13. When the raw solution is discharged from the drain pipe 13, it will directly enter the pickling solution tank 21.

[0053] Furthermore, in this embodiment, a oscillation device is provided on the second placement plate 22, which is used to drive the pickling solution tank 21 to oscillate in order to mix the original solution.

[0054] The above technical solution can be used to easily and evenly mix the various raw solutions in the pickling solution tank 21 using a shaking device.

[0055] Optionally, in this embodiment, a one-way valve is provided in both the interface of the liquid supply pipe 4 and the inner sleeve 15.

[0056] The above technical solution can prevent the raw liquid from flowing back after transportation, ensuring that the raw liquid is only transported in a single direction.

[0057] Working principle: When using, first fill each stock solution tank 3 with the stock solution required for preparing pickling solution, ensure that the pipeline is unobstructed, and ensure that the inlet of the pickling solution tank 21 is aligned with the drain pipe 13;

[0058] The motor 19 is started so that its output shaft drives the drive gear 20 to rotate. The drive gear 20 drives the driven gear 17 to rotate. The driven gear 17 drives the rotating body 7 connected to it to rotate relative to the frame 6. This causes the liquid delivery pipe 8 connected to the rotating body 7 to align with the interface of the liquid supply pipe 4. The electric telescopic rod 16 is started so that it drives the inner sleeve 15 to extend outward, so that the inner sleeve 15 is fitted onto the interface surface of the liquid supply pipe 4 to prevent the original liquid from leaking during the transportation process.

[0059] Then, the metering pump 9 is started. The raw liquid is drawn from the raw liquid tank 3 through the supply pipe 4, the delivery pipe 8 and the metering pump 9 into the outlet pipe 10. The raw liquid enters the funnel 11 through the channel 12. Under the action of gravity, the raw liquid enters the drain pipe 13 from the funnel 11 and is discharged into the pickling solution tank 21 through the drain pipe 13. The pumping continues until the required amount of raw liquid is reached. Then, the metering pump 9 stops pumping and the motor 19 is started to drive the rotating body 7 to continue rotating until the delivery pipe 8 is connected to the interface of the next supply pipe 4. The next type of raw liquid is then pumped. Through the above steps, all raw liquids are pumped into the pickling solution tank 21 according to the required amount, and the proportioning is completed. The efficiency is high.
