Description

Technical Field

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

[0002] As we all know, sampling refers to the process of extracting individuals or samples from a population, that is, the process of experimenting or observing the population. In addition, sampling is mainly divided into two types: random sampling and non-random sampling. The former refers to the sampling method of extracting samples from a population in accordance with the principle of randomization. It is not subjective, including simple random sampling, systematic sampling, cluster sampling and stratified sampling. The latter is a method of extracting samples based on the researcher's opinions, experience or relevant knowledge, which is obviously subjective.

[0003] In the prior art, when sampling and testing liquid chemical products, a sampler is first inserted into a storage tank containing the chemical products for sampling, and then the sampler is moved to a testing device for testing and analysis. However, during this process, the chemical products attached to the bottom of the sampler may drip, which not only generates unnecessary waste, but also poses a safety hazard when the chemical products are corrosive. To this end, we propose a sampling device for chemical use.

[0004] The above information disclosed in the Background section is only for enhancement of understanding of the background of the present disclosure and therefore it may include information that does not constitute the prior art that is already known to one of ordinary skill in the art.

After the connecting block 24 loses the positioning force of the plug 25, the rotating shaft 23 can drive the connecting block 24 to turn 90 degrees under the limiting action of the torsion spring 29, so that the box body 202 can move to just below the sampling cup 11 under the drive of the connecting block 24, so that the box body 202 can collect the dripping liquid when the sampling cup 11 is moved to the detection equipment; the anti-drip mechanism 2 includes a slider movably mounted on the plate body 10 20, a connecting plate 21 is fixedly connected to one side of the slider 20, a bracket 22 is fixedly connected to one side of the connecting plate 21, a rotating shaft 23 is rotatably connected inside the bracket 22, a connecting block 24 is fixedly sleeved on the rotating shaft 23, a box body 202 is fixedly connected to one side of the connecting block 24, a hand wheel 201 is fixedly connected to one end of the rotating shaft 23, a torsion spring 29 is sleeved on the rotating shaft 23, two ends of the torsion spring 29 are respectively fixedly connected to the hand wheel 201 and the connecting block 24, a groove 28 is provided on the outer side of the connecting block 24, a rod body 27 is slidably connected inside the bracket 22, one end of the rod body 27 is fixedly connected to an insert block 25 for inserting into the groove 28, a spring 26 is sleeved on the rod body 27, and two ends of the spring 26 are respectively fixedly connected to the insert block 25 and the bracket 22;
