Description

Technical Field

[0001] The utility model relates to a sampler, in particular to a 200L barrel sampler for electronic-grade hydrofluoric acid. Background Art

[0002] Hydrofluoric acid is highly corrosive and toxic, causing deep skin burns. Fluoride ions, upon entering the body, combine with calcium ions, leading to hypocalcemia, tetany, irregular heartbeats, and even cardiac arrest. Currently, sampling of 200L drums of electronic-grade hydrofluoric acid primarily involves using a pneumatic pump to obtain a sample directly from a sampling bottle below the sampling port. This process generates numerous bubbles, resulting in a high particle content and a lack of representativeness. Utility Model Content

[0003] In view of the above situation, in order to overcome the defects of the existing technology, the utility model provides an electronic-grade hydrofluoric acid 200L barrel sampler, which effectively solves the problem that the current sampling method of electronic-grade hydrofluoric acid 200L barrel is mainly to use a pneumatic pump to directly use a sampling bottle to obtain the sample below the sampling port. A large number of bubbles will be generated during the sampling process, resulting in a high particle content in the sample and a lack of representativeness of the sample.

[0004] To achieve the above-mentioned object, the present invention provides the following technical solution: the present invention includes a chemical reagent storage barrel for storing hydrofluoric acid, a liquid extraction port provided on one side of the top of the chemical reagent storage barrel, and an air inlet and outlet provided on the other side of the top of the chemical reagent storage barrel, and also includes a sampling assembly, wherein the sampling assembly is connected to the chemical reagent storage barrel;

[0005] The sampling assembly includes a sampler, an end cover, a long hose, a short hose, a first hand valve and a second hand valve. The top of the sampler is provided with an end cover, a long hose is inserted and welded on the end cover, a short hose is inserted and welded on one side of the long hose, the long hose is installed with a first hand valve, and the short hose is installed with a second hand valve.

[0006] Preferably, the long hose and the short hose are both made of PFA material.

[0007] Preferably, the first hand valve and the second hand valve are PFA needle-type hand valves.

[0008] Preferably, the sampler is made of PFA material and has a cylindrical bottle-shaped structure.

[0009] Preferably, the long hose is located at the bottom of the sampler, and the short hose is located at the top of the sampler.

[0010] Preferably, the chemical reagent storage barrel is a 200L chemical reagent storage barrel.

[0011] Beneficial effect: When the present invention is used, one end of the long hose is inserted below the liquid level of the chemical reagent storage barrel to complete the installation of the device. When sampling, the first hand valve on the long hose is closed and the second hand valve on the short hose is opened. At this time, the sampler is squeezed hard to deform, and the gas in the sampler is discharged through the short hose, so that the sampler is in a negative pressure state. At this time, the second hand valve is closed and the first hand valve is opened, so that the sampler is deformed and reset, thereby sucking the electronic-grade hydrofluoric acid in the chemical reagent storage barrel into the sampler through the long hose, and the sampling operation is completed. The present invention has a novel structure and an ingenious conception, which ensures the rationality of the sampling process of a 200L barrel of electronic-grade hydrofluoric acid; ensures that no bubbles are generated during the sampling process, and the sample is quite representative, so that the extracted sample can truly reflect the quality of the product in the 200L barrel.
