[0035] like Figures 1-5 As shown, it illustrates an acid-base liquid-assisted weighing device according to an embodiment of the present disclosure, comprising:

[0036] A fixed frame 1 and a measuring cylinder 2, with the measuring cylinder 2 positioned at the bottom of the fixed frame 1;

[0037] The docking extraction component 3 is mounted on the fixed frame 1 and the measuring cylinder 2.

[0038] Reinforcing component 4 is installed at the bottom of the fixing frame 1;

[0039] The extraction assembly 3 includes a circular plate 3-1, which is fixed to the bottom surface of the mounting frame 1. An air tube 3-2 is fixedly connected between the mounting frame 1 and the circular plate 3-1. A connecting cover 3-3 is rotatably connected to the outside of the circular plate 3-1. An internal threaded groove 3-4 is provided around the inner surface of the connecting cover 3-3. An extraction tube 3-5 is installed inside the mounting frame 1. A pair of limiting layers 3-6 are provided on the extraction tube 3-5. A telescopic sleeve 3-7 is movably fitted onto the extraction tube 3-5. A spring 3-8 is fitted onto the outer surface of the extraction tube 3-5. A diaphragm 3-9 is provided at the lower end of the sleeve 3-7. A connecting nozzle 3-10 is provided on the bottom surface of the fixing frame 1. The connecting nozzle 3-10 is connected to the extraction tube 3-5. A docking cover 3-11 is connected to the lower end of the connecting nozzle 3-10 by screw thread. Several sleeve blocks 3-12 are provided on the outer surface of the docking cover 3-11. The measuring cylinder 2 is inserted into the bottom of the docking cover 3-11. Several insert blocks 3-13 are provided around the outer surface of the measuring cylinder 2. The insert blocks 3-13 are fitted into the sleeve blocks 3-12. A control valve 3-14 is installed at the lower end of the measuring cylinder 2.

[0040] In some examples, to achieve the effect of extracting acid and alkali solutions using air pressure, a docking extraction component 3 is designed, including a circular plate 3-1 fixed to the bottom surface of a fixing frame 1. An air pipe 3-2 is fixedly connected between the fixing frame 1 and the circular plate 3-1, which can be connected to an air pressure device. A connecting cover 3-3 with an internally threaded groove 3-4 is rotatably connected to the outside of the circular plate 3-1. It can be installed on the acid and alkali solution tank through the circular plate 3-1 and the connecting cover 3-3. The fixing frame 1 has an extraction tube 3-5. The surface of the extraction tube 3-5 has a pair of limiting layers 3-6. A telescopic sleeve 3-7 is movably fitted on the extraction tube 3-5, and its outer surface is fitted with a spring 3-8 for telescopic movement. The lower end of the sleeve 3-7 is provided with a diaphragm 3-9, which can be supported at the bottom of the acid and alkali solution tank. The sleeve 3-7 can be expanded and contracted according to the depth of the tank. The bottom surface of the fixing frame 1 has a connecting nozzle 3-10. The lower end of the connecting nozzle 3-10 is connected to a docking cover 3-11 by screwing. Several sleeve blocks 3-12 are provided on the outer surface of the docking cover 3-11. The measuring cylinder 2 is inserted into the bottom of the docking cover 3-11. Several insert blocks 3-13 are arranged around its outer surface and are locked in the sleeve blocks 3-12 by rotation. A control valve 3-14 is installed at the lower end of the measuring cylinder 2. The control valve 3-14 can be opened to discharge directly to the outside, or the measuring cylinder 2 can be removed.

[0041] like Figures 1-5 As shown, this embodiment proposes a reinforcement component 4, which includes a base rod 4-1. The base rod 4-1 is fixed to the bottom surface of the fixing frame 1. A support bolt 4-2 is connected to the base rod 4-1 by threaded connection. A clamping plate 4-3 is provided at one end of the support bolt 4-2.

[0042] In some examples, in order to strengthen the fixed connection with the acid and alkali liquid tank, the bottom surface of the fixing frame 1 is provided with a bottom rod 4-1, and a support bolt 4-2 is connected to the bottom plate by a threaded connection. One end of the support bolt 4-2 is provided with a pressure plate 4-3, and the support bolt 4-2 can be turned to push the pressure plate 4-3 against the surface of the material tank.

[0043] For example, such as Figure 1 As shown, the graduated layer 5 is provided on the surface of the graduated cylinder 2.

[0044] In some examples, a graduated layer 5 is provided to facilitate direct viewing of the amount of acid or alkali solution collected.

[0045] For example, such as Figure 1 As shown, the outer surface of the connecting cover 3-3 has a toothed structure around its perimeter.

[0046] In some examples, the toothed surface provides better anti-slip properties and makes it easier to manually twist the connecting cap 3-3.

[0047] For example, such as Figure 2 As shown, the bottom surface of the cover 3-9 has an inclined structural surface around it.

[0048] In some examples, the inclined structural surface does not adhere to the bottom surface of the acid / alkali solution tank, making it easier for the acid / alkali solution to enter the extraction tube 3-5.

[0049] For example, such as Figure 5 As shown, a sealing ring 6 is provided around the side surface of the limiting layer 3-6 located at the lower end of the extraction tube 3-5.

[0050] In some examples, a sealing ring 6 is provided to maintain a sealed fit between the extraction tube 3-5 and the telescopic sleeve 3-7.

[0051] For example, such as Figure 2 As shown, both the extraction tube 3-5 and the trachea 3-2 are made of rigid materials.

[0052] In some examples, rigid material structures are used to prevent deformation caused by air pressure.

[0053] In actual use, first fix the fixing frame 1 to the acid and alkali solution tank, insert the telescopic sleeve 3-7 and the air pipe 3-2 into the pickling solution tank, then tighten the connecting cover 3-3 to connect with the pickling solution tank, and then tighten the support bolt 4-2 inside the bottom rod 4-1 to make the clamping plate 4-3 press tightly against the surface of the material tank to ensure the stability of the device. Next, connect the air pipe 3-2 to the air pressure equipment, and use air pressure to extract the acid and alkali solution through the extraction pipe 3-5. The inclined structure of the bottom surface of the diaphragm 3-9 facilitates the entry of the acid and alkali solution. The shrink tube 3-7 and spring 3-8 can be adjusted according to the depth of the barrel. The sealing ring 6 of the limiting layer 3-6 at the lower end of the extraction tube 3-5 ensures the sealing effect. The extracted acid and alkali solutions enter the measuring cylinder 2 through the connecting nozzle 3-10 and the docking cover 3-11. The insert block 3-13 on the outer surface of the measuring cylinder 2 cooperates with the sleeve block 3-12 of the docking cover 3-11 to fix it. The liquid volume is controlled by observing the scale layer 5 on the measuring cylinder 2. Finally, the control valve 3-14 at the lower end of the measuring cylinder 2 can be opened to take out the liquid. Alternatively, the measuring cylinder 2 can be removed.

[0054] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
