Description

Technical Field

[0001] The utility model relates to the technical field of laboratory equipment, in particular to an acid solution soaking, cleaning and drying device for laboratory container instruments. Background Art

[0002] Glass and plastic containers, such as beakers, conical flasks, volumetric flasks, graduated cylinders, and reagent bottles, are commonly used in chemical experiments. In power plant water vapor analysis, the impurity content in the water vapor is very low, typically a few micrograms per liter. To ensure the accuracy of the analysis, the instruments must be pre-soaked or boiled in 1:1 hydrochloric acid or 1:1 nitric acid, then rinsed three to five times with tap water, then two to three times with demineralized water, and finally dried for use.

[0003] Existing laboratory acid immersion tanks consist of two parts: an inner tank and an outer tank, and are only designed for acid immersion. During the acid immersion cleaning process, laboratory instruments must be cleaned manually, wearing acid and alkali protective gear, and removed from the tank (this process can cause acidic gases to escape, polluting the environment and endangering the health of the laboratory technician). The instruments are then rinsed with tap water and demineralized water, and finally dried for later use. This process is labor-intensive and environmentally polluting. Utility Model Content

[0048] Figure 5 This is a schematic diagram of a placement basket provided according to an embodiment of the present invention, in which the instrument bottle mouth is positioned downward. Figure 6 This is a schematic diagram of a placement basket located at the level of the instrument bottle mouth according to an embodiment of the present invention. Figure 7 This is a schematic diagram of a placement basket provided according to an embodiment of the present invention, in which the instrument bottle mouth faces upward. Figure 5-7 As shown, the embodiment of the present invention provides an acid solution soaking, cleaning and drying device for laboratory container instruments, and the working process is as follows:

[0049] ① Place the instrument: Check that all valves on the delivery pipeline 8 are in the closed position. Squeeze the handle 19 and push the sliding door 7 upwards to open the immersion box (such as Figure 2 Put the rotating shaft 15 of the control rod 6 through the rotating shaft hole 14 of the placing basket 3 and fix the placing basket 3 with the fixing nut. Put the container 17 to be cleaned (such as beaker, Erlenmeyer flask, volumetric flask, graduated cylinder, etc.) with the opening facing downward and turn it upside down on the supporting rod 22 of the placing basket 3. Place one (such as Figure 4 Then, put the basket cover 16 on the placement basket 3, fasten the four buckles 20 one by one, and carefully check that the buckles and the buckle edges are tightly fastened.

[0050] When the instrument is placed, the basket 3 is located Figure 5 Position shown with all instrument openings facing downward.

[0051] ② Adding Acid: For initial use, add acid directly into the immersion tank 2 through the opening of the sliding door 7. Then close the sliding door 7. If acid is already in the storage tank 4, close the sliding door 7, turn on the power switch, start the delivery pump 23, open the first valve 26, the third valve 28, and the fourth valve 29, and inject the acid into the immersion tank 2. When the acid level reaches the desired level, stop the delivery pump 23 and close the first valve 26, the third valve 28, and the fourth valve 29.

[0052] ③Immerse the instrument:

[0053] a. The shaft 15 is rotated 90° by the control lever 6, and the basket 3 is placed in Figure 6 The position shown in the figure is that the opening direction of each instrument is consistent with the horizontal direction. At this time, the control rod 6 controls the placement basket 3 to descend. When the control rod 6 descends to the middle position of the immersion box 2 (such as Figure 6 As shown), the rotating shaft 15 drives the placement basket 3 to rotate 90 degrees, and the placement basket 3 is now located Figure 7 In the position shown, all instrument openings are facing upward, and all instruments are below the acid level. During this process, the acid enters the container through the acid flow holes and the container opening, fully immersing the container. The immersion time can be set according to experimental requirements (such as 8 hours, 24 hours, 48 ​​hours, etc.).

[0054] b. After soaking for the set time, the rotating shaft 15 drives the basket 3 to rotate 90 degrees, so that the basket 3 is perpendicular to the horizontal direction, and the control rod 6 controls the basket 3 to rise to Figure 6 As shown in the figure, at this time, most of the acid in the basket 3 has flowed out, and then the basket 3 is driven by the rotating shaft 15 to rotate 90 degrees, and the basket 3 is located at Figure 5 In the position shown, all container openings are facing downwards, and the acid in the basket 3 and the container is completely drained.

[0055] c. After the acid liquid is completely drained, the fifth valve 30 is opened to drain all the acid liquid into the storage tank 4 for storage, and the fifth valve 30 is closed.

[0056] ④Washing equipment:

[0057] Open the fourth valve 29 and the sixth valve 31 to supply tap water into the immersion tank 2. When the tap water reaches the desired level, close the fourth valve 29 and the sixth valve 31. Repeat steps ab for the instrument immersion process twice (note: the instrument only needs to be washed, so the soaking time requirement is not required). After completing these steps, open the seventh valve 32 to drain the tap water from the immersion tank 2, then close the seventh valve 32. Repeat these steps twice to thoroughly rinse the instrument with tap water.

[0058] Open the fourth valve 29 and the eighth valve 33 to deliver deionized water into the immersion tank 2. When the deionized water reaches the desired level, close the fourth valve 29 and the eighth valve 33. Repeat steps a to b for the instrument soaking process twice (note: the instrument only needs to be washed, so the soaking time requirement is not required). After completing these steps, open the seventh valve 32 to drain the deionized water from the immersion tank 2, then close the seventh valve 32. Repeat these steps twice to thoroughly rinse the instrument with deionized water.

[0059] ⑤ Drying: After the desalted water is discharged, open the ninth valve 34 and the tenth valve 35, start the drying fan 13, and deliver hot air to the immersion box 2 to dry the instrument (the running time of the drying fan 13 can be timed).

[0060] ⑥ Take out the instrument: After the drying fan 13 stops running, open the sliding door 7, remove the basket cover 16 of the placement basket 3, and take out the dried instruments one by one. The placement basket 3 can still be placed in the soaking box 2, or it can be taken out and placed separately.

[0061] ⑦ Reuse: Since the acid solution can be reused, when the instrument needs to be soaked again, the first valve 26 and the third valve 28 can be opened (the other valves are closed at this time), and the delivery pump 23 can be started to transfer the acid solution in the storage tank 4 into the soaking box 2 for soaking and treating the instrument again. If the acid solution is used frequently and is seriously contaminated, the third valve 28 and the fourth valve 29 can be opened to drain the acid solution and replace the acid solution.

[0062] From the above description, it can be seen that the embodiment of the utility model provides an acid immersion cleaning and drying device for laboratory container instruments, which has the functions of acid immersion, desalted water cleaning and hot air drying. Laboratory container instruments do not need to be cleaned manually, and can be completed automatically, saving labor costs, reducing environmental pollution, and alleviating the technical problems of labor consumption and environmental pollution in the process of manual acid immersion cleaning of laboratory instruments.
