Description

Technical Field

[0001] The utility model belongs to the technical field of chemical raw material sampling, in particular to a sampling and detection component for the production of liquid chemical raw materials. Background Art

[0002] Chemical raw materials are divided into two categories: organic chemical raw materials and inorganic chemical raw materials. Organic chemical raw materials are divided into alkanes and their derivatives, alkenes and their derivatives, alkynes and their derivatives, quinones, aldehydes, alcohols, ketones and other types. Inorganic chemical raw materials are chemical minerals containing sulfur, sodium, phosphorus, potassium, calcium, coal, oil, natural gas, air, water, etc. In addition, industrial by-products and waste are also raw materials for inorganic chemicals. Chemical raw materials exist in liquid, solid and gaseous forms. In the production process of chemical raw materials, liquid chemical raw materials generally need to be tested, so chemical raw material sampling equipment is needed for sampling.

[0003] In a Chinese patent with publication number CN218180324U, a safe sampling and detection device for harmful chemical raw materials is disclosed. The patent connects an external power supply through a motor in a stirring mechanism. The motor can be driven by the meshing of a first bevel gear and a second bevel gear to drive a cylinder and a plurality of stirring rods to rotate. Then, when the bottom of the cylinder and the tube body penetrates into the interior of the chemical raw material, the cylinder and the plurality of stirring rods can mix the chemical raw material. Then, when the pump body is connected to an external power supply, the tube body can sample the stirred chemical raw material to improve the accuracy of subsequent detection of the chemical raw material. However, in general, when sampling different types of liquid chemical raw materials, different types and sizes of sampling tubes are required. Therefore, different types of clamps are required to fix the sampling tubes. The operation is cumbersome and time-consuming, resulting in low work efficiency and affecting the sampling and detection of chemical raw materials.
