Description

Technical Field

[0001] The utility model relates to the technical field of hydrofluoric acid, in particular to a hydrofluoric acid sampling device. Background Technique

[0002] Hydrofluoric acid is an aqueous solution of hydrogen fluoride gas. It is a colorless fuming liquid with a strong pungent odor. It is highly corrosive, highly toxic, soluble in water and ethanol, and slightly soluble in ether. Hydrofluoric acid has strong corrosiveness and can strongly corrode metals, glass and silicon-containing substances. At the same time, it is extremely harmful to the human body. Once a person inhales the vapor by mistake or comes into contact with the skin, it will cause incurable organic damage. In addition to being used as an etchant, hydrofluoric acid can also be used as a refrigerant. In recent years, with the rapid development of the semiconductor industry, hydrofluoric acid has also become one of the key basic chemical materials in the production process of microelectronic products and can be used for the cleaning and corrosion of integrated circuit and very large scale integrated circuit chips.

[0003] For example, in the "A Stable and Clean Hydrofluoric Acid Sampling Device" with the Chinese patent publication number CN219757804U, this utility model discloses a stable and clean hydrofluoric acid sampling device, which can be applied to the technical field of hydrofluoric acid sampling. It includes a box body and a sampling tube. The box body is provided with a sampling control room, a sampling room and a waste liquid room from top to bottom. Among them, the sampling control room and the sampling room are provided with box doors, and a first partition is provided between the two rooms. A tube through hole is provided on the first partition. The sampling room is provided with a detachable sampling base. The sampling base includes three-sided enclosures, a base and support columns. Opposite sides of the three-sided enclosures are symmetrically provided with retractable fixed handles. Through the setting of the retractable fixed handles of the sampling base, the stable fixation of sampling bottles of different specifications is realized, and the sampling failure caused by the tipping of the sampling bottle during the sampling process or the tipping of the sampled liquid during the transfer sampling process is avoided, which may cause harm to the human body and the surrounding environment.

[0004] However, in actual use, there is a problem that it is not convenient to take out the sampled sampling bottle from the box body. When the hydrofluoric acid is collected in the sampling bottle in the box body, it is necessary to reach into the box body to take out the sampling bottle, which is likely to cause collision due to the narrow space in the box body, resulting in the spillage of hydrofluoric acid, and it is not convenient to take out the hydrofluoric acid in the sampling bottle. Therefore, a hydrofluoric acid sampling device is proposed to solve the above-mentioned problems. Content of the Utility Model
