There are as many as 500,000 to 7 million kinds of chemicals in the world, and more than 100,000 kinds of chemicals are sold and circulated on the market. In addition, more than 1,000 new chemicals are introduced every year, and 15 to 200 of them are considered carcinogens. Chemical raw materials need to be tested for purity and impurities during production and use. Some chemical raw materials can be directly sampled and tested by mixing them with reactants. The concentration of chemical raw materials can be tested by observing the degree of reaction. The chemical raw materials to be tested and the reactants are poured into a test tube together, and stirred with a glass rod for sufficient reaction. The dissolved and diluted solution is then dispensed into multiple groups of test bottles through a pipette or a pipette gun, and the solution in the test bottle is finally tested. At this time, a chemical raw material detection device is needed.

[0003] After searching, it is found that the utility model patent with announcement number CN219210037U discloses a detection device for chemical raw materials, including a connecting main board, the bottom end of which is fixedly connected to a supporting base by bolts, the top of which is slidably connected to a placing plate, the bottom end of which is fixedly connected to a sliding block, a sliding groove is provided inside the connecting main board at the position of the sliding block, an auxiliary plate is fixedly connected to the rear side of the connecting main board, a test tube is placed inside the placing plate, and a material placing dish is movably connected to one side of the top of the auxiliary plate; the detection device for chemical raw materials is provided with an auxiliary plate, a material placing dish, a drainage tube, an anti-overflow baffle, a support plate and an electric telescopic rod during use, and through the mutual cooperation of the components, the electric telescopic rod of the detection device for chemical raw materials drives the material placing dish and the drainage tube to descend, and the reactant is injected into the test tube. At the same time, the anti-overflow baffle prevents the raw materials from overflowing due to the violent reaction inside the test tube, thereby improving the stability of the detection device for chemical raw materials.

[0004] In the above patented technical solution, by providing an auxiliary plate, a material placing dish, a drainage tube, an anti-overflow baffle, a support plate and an electric telescopic rod, through the mutual cooperation of the components, the electric telescopic rod of the chemical raw material detection device drives the material placing dish and the drainage tube to descend, and injects the reactant into the test tube.
