Description

Technical Field

[0001] The utility model relates to the technical field of chemical reagent mixing, in particular to a reagent mixing device for analytical chemistry. Background Art

[0002] Analytical chemistry is a science about the analytical methods and theories for studying the chemical information such as the composition, content, structure and morphology of substances, and is an important branch of chemistry. It is to identify the components contained in a substance, what components the substance is composed of, measure the relative content of various components, and study the molecular structure or crystal of the substance. The main tasks of analytical chemistry are to identify the chemical composition (elements, ions, functional groups, or compounds) of substances, determine the content of relevant components of substances, determine the structure (chemical structure, crystal structure, spatial distribution) and existence form (valence state, coordination state, crystalline state) of substances and their relationship with the properties of substances, etc.

[0003] In the current experimental research of analytical chemistry, it is often necessary to mix various chemical reagents. In some experiments with slow reaction rates or involving the dissolution of some poorly soluble substances, a large amount of waiting time is required. By accelerating the mixing of reagents, the reaction rate and dissolution rate can be increased, thereby reducing the experimental period and improving the experimental efficiency. However, at present, there is a lack of targeted auxiliary reagent mixing devices for analytical chemistry. Most are carried out by manual mixing, with a large operation difficulty, unsatisfactory effects, and the need for manual preparation of chemical reagents, resulting in errors and low safety. There may already be technical solutions to solve the above technical problems. In view of this, this case wants to provide a replacement or alternative technical solution.

[0022] Embodiment: Refer to Figures 1-3, a reagent mixing device for analytical chemistry, comprising a workbench 1. A first servo motor 2 is assembled on the upper wall of the workbench 1. A first support rod 3 is assembled on the driving end of the first servo motor 2. A clamping tray 4 is assembled on the first support rod 3. Eight sockets are opened on the clamping tray 4. A quantitative batching structure is assembled on the workbench 1 and on one side of the first servo motor 2; the quantitative batching structure includes a second servo motor 5, a second support rod 6, an assembly tray 7, a plurality of syringes 8 and a pushing part; the second servo motor 5 is arranged on the workbench 1 and on one side of the first servo motor 2. The second support rod 6 is arranged on the driving end of the second servo motor 5. The assembly tray 7 is arranged on the second support rod 6 and above the clamping tray 4. The plurality of syringes 8 are equidistantly embedded on the assembly tray 7. The pushing part is arranged on the workbench 1 and on one side of the second servo motor 5; the pushing part includes a mounting frame 9, an electric push rod 10 and a top plate 11; the mounting frame 9 is arranged on the workbench 1 and on one side of the second servo motor 5. The electric push rod 10 is arranged on the mounting frame 9 and above one of the syringes 8. The top plate 11 is arranged on the telescopic end of the electric push rod 10; a rubber ring 12 is respectively embedded in each socket; an anti-slip rubber layer 13 is assembled on the lower wall of the workbench 1; handlebars 14 are respectively assembled on both side walls of the workbench 1;

[0023] The specific working principle is as follows:

[0024] The staff assembles the syringes 8 filled with the formulation one by one onto the assembly tray 7. After the assembly is completed, the reagent bottles filled with the stock solution are respectively clamped into the sockets on the clamping tray 4 one by one. The rubber ring 12 increases the friction force and improves the stability of the reagent bottles. After preparation, the electric push rod 10 installed on the mounting frame 9 pushes the top plate 11 installed on its telescopic end to descend, squeezing the push rod of the syringe 8. The syringe 8 extrudes the formulation into the reagent bottle below. After extruding a quantitative formulation, the electric push rod 10 resets and rises. The second servo motor 5 drives the second support rod 6 installed on its driving end to rotate. After the next syringe 8 is located above the reagent bottle, it stops. The electric push rod 10 pushes the top plate 11 to descend again to extrude the formulation, performing the automated ratio of the reagent. After the ratio is completed, the first servo motor 2 drives the first support rod 3 installed on its driving end to rotate, so that the next new reagent bottle is located below the syringe 8, and the above-mentioned rising steps are repeated to perform the automated quantitative ratio of the reagent. The staff buckles the cover onto the reagent bottle with the ratio completed to prevent the liquid from overflowing during mixing. After the ratio of all the reagent bottles on the clamping tray 4 is completed, the first servo motor 2 drives the first support rod 3 to rotate reciprocally to perform the shaking work, accelerating the mixing speed of the reagent and improving the work efficiency. The anti-slip rubber layer 13 is used to increase the friction force of the device and prevent it from sliding on the placement plane. The handlebars 14 facilitate the staff to carry and move.
