[0033] The following is combined with Figure 1-4 This application is described in further detail.

[0034] The present application embodiment discloses a laboratory low-multiple pickling process system, such as Figure 1As shown, it includes a pickling box 1, a connecting pipe 2 and an induced draft fan 3. An absorption hood 4 is installed on the pickling box 1. A connecting hose 21 is connected to the connecting pipe 2, and the connecting hose 21 is connected to the absorption hood 4. One end of the connecting pipe 2 is connected to a primary acid mist absorption tower 33, and the input end of the induced draft fan 3 is connected to an air inlet pipe 31, and the end of the air inlet pipe 31 away from the induced draft fan 3 is connected to the primary acid mist absorption tower 33; the output end of the induced draft fan 3 is connected to an air outlet pipe 32, and the end of the air outlet pipe 32 away from the induced draft fan 3 is connected to a secondary acid mist absorption tower 34, and the secondary acid mist absorption tower 34 is connected to an exhaust pipe 341. The acid mist generated when the acid liquid is heated enters the primary acid mist absorption tower 33 through the connecting hose 21 under the action of the induced draft fan 3. The primary acid mist absorption tower 33 absorbs the acid mist. The treated acid mist enters the secondary acid mist absorption tower 34 through the air inlet pipe 31 and the air outlet pipe 32. The secondary acid mist absorption tower 34 absorbs the acid mist again and then discharges it into the air from the exhaust pipe 341, thereby reducing the possibility of the acid mist directly flowing into the air.

[0035] like Figure 2 As shown, a pickling tank 11 is provided in the pickling tank 1, and acid is placed in the pickling tank 11. A liquid inlet pipe 14 and a liquid outlet pipe 15 are connected to the pickling tank 11, and both the liquid inlet pipe 14 and the liquid outlet pipe 15 are connected to the pickling tank 11, and electromagnetic valves are installed on the liquid inlet pipe 14 and the liquid outlet pipe 15. When acid needs to be added to the pickling tank 11, the operator can open the electromagnetic valve on the liquid inlet pipe 14 to add the acid to the pickling tank 11 through the liquid inlet pipe 14; when the acid in the pickling tank 11 needs to be discharged, the operator can open the electromagnetic valve on the liquid outlet pipe 15 to discharge the acid in the pickling tank 11 from the liquid outlet pipe 15, which is convenient for adding or discharging the acid in the pickling tank 11.

The support block can support the support frame 13. A through hole is opened on the support frame 13, and the sample is placed on the support frame 13. When the sample needs to be pickled, the operator can place the sample on the support frame 13, and the support frame 13 can support the sample to facilitate the pickling work of the sample.

[0037] like Figure 3 As shown, a heating rod 16 is installed in the pickling tank 1, and a positioning plate 17 is fixedly connected to the bottom of the pickling tank 11. The positioning plate 17 is made of glass fiber reinforced plastics, and a positioning groove 171 is provided on the positioning plate 17. The positioning groove 171 is used for the heating rod 16 to be embedded. When the heating rod 16 needs to be installed, the heating rod 16 is moved so that the heating rod 16 is embedded in the positioning groove 171. The positioning groove 171 can limit the heating rod 16 so that the heating rod 16 is fixed in the pickling tank 11, which is convenient for the installation of the heating rod 16, so that the heating rod 16 heats the acid solution.

[0038] like Figure 2 As shown, a thermometer 18 and a liquid level gauge 19 are installed on the pickling box 1; the thermometer 18 can display the temperature of the acid solution in the pickling tank 11, so that the operator can heat the acid solution to a suitable temperature through the heating rod 16 to reduce the possibility of temperature deviation of the acid solution; the liquid level gauge 19 can display the liquid level of the acid solution in the pickling tank 11, so that the operator can add the required amount of acid solution into the pickling tank 11, thereby facilitating the pickling work of the sample.

[0039] like Figure 4 As shown, the absorption cover 4 and the pickling box 1 slide relative to each other, and the sliding direction of the absorption cover 4 is the vertical direction; a rubber plate 41 is installed on the side of the absorption cover 4 facing the pickling box 1, and the absorption cover 4 can drive the rubber plate 41 to move to fit with the pickling box 1. The rubber plate 41 can improve the sealing degree between the absorption cover 4 and the pickling box 1, and reduce the possibility of the acid mist generated by the heating of the acid solution flowing into the air. A control component 5 is provided on the pickling box 1, and the control component 5 includes a mounting plate 51, a sliding plate 52 and a control member.

The movement of the sliding plate 52 can drive the movement of the absorption cover 4, so that the absorption cover 4 moves downward and moves to fit with the pickling box 1. The absorption cover 4 can block the pickling tank 11, reduce the possibility of acid mist directly flowing into the air, and facilitate the acid mist to enter the connecting hose 21 for absorption treatment.

[0040] The implementation principle of a laboratory low-multiple pickling process system in the present application embodiment is as follows:

[0041] The operator places the sample on the support frame 13, and drives the absorption cover 4 to move by controlling the cylinder 53, so that the absorption cover 4 moves to fit the pickling box 1; injects acid into the pickling tank 11 through the liquid inlet pipe 14, and injects an appropriate amount of acid according to the liquid level meter 19; heats the acid through the heating rod 16, controls the temperature of the acid according to the thermometer 18, and then performs pickling work on the sample; when the pickling work is completed, the acid in the pickling tank 11 is discharged through the liquid outlet pipe 15 to facilitate the subsequent use of the acid.
