Description

Technical Field

[0001] This application relates to the field of detection technology, specifically a palladium content detection device. Background Technology

[0002] Palladium is a precious metal, but its persistent supply shortage and high cost make its recycling extremely important. Meanwhile, untreated palladium wastewater discharged directly can harm the environment and ecosystems. By detecting the palladium content in palladium wastewater, we can understand its concentration and distribution, allowing us to develop appropriate treatment plans to ensure the wastewater meets environmental standards before discharge and minimize pollution.

[0003] Chemical titration is a simple, rapid, and accurate method for detecting palladium content in palladium waste liquid.

[0004] For example, patent CN221782198U discloses an automatic titration detection device. This patent, by setting up a titration material tank and a stirring titration mechanism, makes it convenient to add titration liquid through the titration material tank during detection. The stirring titration mechanism is controlled by the control panel to mix and discharge the raw materials to be mixed, and then the titration detector is used for detection, thereby improving the accuracy of titration and the convenience of use.

[0005] In actual titration, a constant titration rate is usually used. However, different palladium waste solutions have different reaction rates due to differences in their composition and concentration. For some palladium waste solutions that react rapidly, a slow titration rate will waste a lot of time, while for some palladium waste solutions that react slowly, a fast titration rate may lead to incomplete reaction. If the titration rate cannot be adjusted, it is impossible to optimize it according to the characteristics of different palladium waste solutions, thus affecting the titration efficiency.

[0006] Therefore, it is necessary to provide a palladium content detection device to solve the above problems.

[0007] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0033] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0034] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0035] like Figures 1-2As shown, this application provides a palladium content detection device, including a frame 1 and a tank 2 fixedly installed inside the frame 1. The tank 2 is used to contain the palladium waste liquid sample to be detected and to provide a stable environment for palladium content detection. The tank 2 is transparent to facilitate observation.

[0036] Meanwhile, the upper end of the tank 2 is fixedly provided with a feed inlet 3, which is used to add sample palladium waste liquid into the tank 2. A stirring mechanism 4 is rotatably provided inside the tank 2. The stirring mechanism 4 is used to improve the mixing uniformity and reaction rate of the solution by stirring, thereby improving the detection efficiency.

[0037] The stirring mechanism 4 includes a bracket 40 fixedly installed on the upper end of the tank body 2. A first motor 41 is fixedly installed on the bracket 40. The output end of the first motor 41 passes through the tank body 2 and a stirring shaft 43 is fixedly installed thereon. At the same time, a shaft seal 42 is fixedly installed at the connection between the output end of the first motor 41 and the tank body 2. The shaft seal 42 is suitable for preventing leakage and contamination by bacteria.

[0038] Meanwhile, multiple sets of stirring rods 44 are fixedly installed on the stirring shaft 43. The stirring rods 44 generate shear force and turbulence by rotating, so as to fully mix the palladium waste liquid with other reactants.

[0039] In order to prevent reactants from adhering to the inner wall of tank 2 and thus affecting the full mixing of palladium waste liquid with other reactants, multiple sets of stirring rods 44 are hinged with scrapers 45. The scrapers 45 are set to fit against the inner side wall and bottom of tank 2 to scrape off the reactants adhering to the inner wall of tank 2 and ensure that the reactants fully participate in the reaction.

[0040] Meanwhile, a temporary storage cylinder 5 is fixedly installed at the upper end of the tank body 2. The temporary storage cylinder 5 is used to store the titration reagent added to the tank body 2 for palladium content detection. The upper end of the temporary storage cylinder 5 is fixedly installed with an inlet 8, which is used to introduce the titration reagent into the temporary storage cylinder 5 for use. The lower end of the temporary storage cylinder 5 is fixedly installed with a dropper 7, so that the titration reagent inside the temporary storage cylinder 5 can be accurately dripped into the tank body 2 through the dropper 7.

[0041] Before the palladium waste liquid reacts, the prepared palladium waste liquid sample is slowly added into the tank 2 through the feed port 3. After all the palladium waste liquid samples have been added, the feed port 3 can be closed.

[0042] At this time, the titration reagent is introduced into the storage cylinder 5 through the inlet 8, and then the titration reagent is added into the tank 2 through the dropper 7 at the lower end of the storage cylinder 5 to detect the palladium content. During the titration process, the first motor 41 of the stirring mechanism 4 is started, so that the stirring shaft 43 and the stirring rod 44 start to rotate. The rotation of the stirring rod 44 will generate strong shear force and turbulence, which will fully mix the palladium waste liquid and the titration reagent together, so that they can be fully mixed and reacted.

[0043] Finally, staff can observe the titration endpoint through the transparent container 2 to determine the palladium content through subsequent calculations;

[0044] like Figure 1 and Figures 3-4 As shown, in order to adjust the titration speed during the titration process, a speed regulating mechanism 6 is fixedly installed at the connection between the temporary storage cylinder 5 and the nozzle 7. The speed regulating mechanism 6 includes multiple sets of support columns 60 fixedly installed on the temporary storage cylinder 5. The support columns 60 extend through the tank body 2 into the interior and are fixedly installed with a cover 61. The cover 61 is fixedly installed between the temporary storage cylinder 5 and the nozzle 7 through the support columns 60. A through hole is provided in the middle of the cover 61, which connects the temporary storage cylinder 5 and the nozzle 7 so that the titrant can be smoothly introduced into the tank body 2.

[0045] Meanwhile, multiple sets of arc-shaped rings 62 are rotatably arranged inside the cover 61, and arc-shaped teeth 63 are fixedly arranged between the multiple sets of arc-shaped rings 62, and reverse teeth are arranged on the outer side of one set of arc-shaped rings 62.

[0046] A fixing ring 67 is fixedly installed on the temporary storage cylinder 5 outside the tank body 2. A second motor 66 is fixedly installed on the fixing ring 67. A gear 65 is fixedly installed at the output end of the second motor 66. The gear 65 passes through the cover 61 and meshes with the reverse teeth on the outside of the arc ring 62, thereby driving the second motor 66. The arc ring 62 can be rotated through the gear 65.

[0047] Furthermore, multiple sets of baffles 64 are rotatably arranged inside the housing 61, located on the inner side of the arc-shaped ring 62. These baffles 64 are used to block the titrant inside the temporary storage cylinder 5. A serration is fixedly provided at one end of the baffle 64 near the arc-shaped tooth 63. The serration meshes with the arc-shaped tooth 63. Thus, when the second motor 66 drives the arc-shaped ring 62 to rotate through the gear 65, it can drive the multiple sets of baffles 64 to converge towards the center. When the multiple sets of baffles 64 converge, the through hole in the middle of the housing 61 is reduced, thereby reducing the speed at which the titrant is introduced into the dropper 7, and thus achieving the purpose of reducing the titration speed.

[0048] When performing titration, the titrant is first introduced into the storage cylinder 5. At the same time, the second motor 66 is started, which drives the arc ring 62 to rotate through the gear 65. This causes multiple sets of baffles 64 to converge at the center until the channel from the storage cylinder 5 to the nozzle 7 is narrowed, thereby reducing the speed at which the titrant enters the tank 2 and thus reducing the titration speed. When it is necessary to speed up the titration, the baffles 64 are driven in the opposite direction to move away from the surrounding areas, which will widen the channel from the storage cylinder 5 to the nozzle 7 and thus speed up the titration.

[0049] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
