Description

Technical Field

[0001] The utility model relates to the technical field of chemical industry, in particular to a sampling device for chemical raw materials. Background Art

[0002] Chemical raw materials are raw materials produced by chemical methods. They include inorganic chemical products other than fertilizers, inorganic pesticides, inorganic pigments, and various products made mainly from polymer materials in the organic synthesis industry. They are specifically divided into: basic chemical raw materials, including hydrochloric acid, sulfuric acid, nitric acid, soda ash, caustic soda, and various inorganic salts. They are important raw materials for various industrial sectors. In addition to being widely used in the chemical industry, they are also used in mining, metallurgy, machinery, and light industry.

[0003] After the existing chemical raw materials are produced, they need to be taken out using a sampling device, and then the product is tested to see if it is qualified. However, the existing sampling devices are generally straight-barreled insertion samplers, which directly insert the chemical raw materials into the inner wall of the sampler. However, some chemical raw materials are in powder form. When sampling powdered chemical raw materials, they may be blocked in the inner wall of the straight-barreled sampler, and additional tools are needed to move them to the outside, which makes it inconvenient to use. Moreover, only one position can be sampled at the same time, which reduces the diversity when sampling, makes it impossible to compare the results after testing, and affects the raw material quality judgment results. Therefore, a sampling device for chemical raw materials is proposed to solve the above problems. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a sampling device for chemical raw materials, comprising a top plate, a sampling assembly is arranged at the bottom of the top plate;
