Description

Technical Field

[0001] The utility model relates to the technical field of crane pipes, in particular to an automatic sampling and analysis device for tank truck filling. Background Art

[0002] The main function of tank truck sampling is to ensure transportation safety, control quality, and improve energy utilization efficiency. Tank truck sampling is an important instrument detection work. Through sampling, fuel consumption problems can be discovered in time, and then energy-saving measures can be formulated to improve energy utilization efficiency. In addition, sampling can also control product quality and ensure that the substances in the tank truck meet the predetermined quality standards, thereby ensuring product quality and safety. For this purpose, an automatic sampling and analysis device for tank truck filling is proposed.

[0003] The existing Chinese utility model patent with reference publication number CN221377247U discloses an automatic sampler for a tank truck, which belongs to the field of crane pipe technology. In this technical solution, an automatic sampler for a tank truck is disclosed. A sampling mechanism for extracting a medium in the tank truck is provided in the liquid inlet pipe. The sampling mechanism includes a high-level sampling pipe, a low-level sampling pipe and a sampling pump. The high-level sampling pipe and the low-level sampling pipe are connected to the sampling pump through a tee pipe. A reflux pipe for transporting the medium into the tank truck is connected to the sampling pump. A sampling valve for extracting material is provided on the reflux pipe. The high-level sampling pipe, the low-level sampling pipe and the reflux pipe are respectively extended and arranged along the liquid inlet pipe, the connecting pipe and the vertical pipe. The sampling pump extracts the upper and lower media inside the tank truck through the high-level sampling pipe and the low-level sampling pipe respectively. The extracted medium flows into the reflux pipe through the sampling pump. The reflux pipe samples the extracted medium using the sampling valve, and then returns the excess medium to the interior of the tank truck through the reflux pipe, so as to achieve an automatic sampling function. Manual sampling is unnecessary and resources are not wasted, thereby solving the problem of low efficiency in tank truck sampling.

[0004] Based on the search of the above patents and combined with the equipment in the prior art, it was found that since the current product analysis relies on manual switching and adjustment of sampling analysis, due to the different experience and proficiency of the operators, it is easy to cause the sampling tube to be not cleanly purged and contaminate the analyzer sensor, resulting in inaccurate data analysis. The existence of these problems has affected the use of the device. Utility Model Content
