Description

Technical Field

[0001] This utility model relates to the field of sampling equipment technology, specifically to a real-time online sampling machine. Background Technology

[0002] In industrial production processes, precise sampling and analysis of materials are often necessary to ensure product quality and process stability. However, directly taking materials from storage tanks presents several problems. Materials in storage tanks may stratify or deposit due to density differences, temperature gradients, or other physical processes, resulting in uneven material distribution. Direct sampling from storage tanks may not guarantee uniform material samples. Therefore, we propose a real-time online sampling machine. Utility Model Content

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] See attached document Figure 1-4A real-time online sampling machine includes a sampling valve body 1, a three-way pipe 2, and a sampling cylinder 3. One horizontal end of the three-way pipe 2 extends into the sampling valve body 1. An inclined notch is formed on the three-way pipe 2 within the sampling valve body 1, aligning with the flow direction of the sampling valve body 1 to receive material within the sampling valve body 1, directly connecting to the material source and reducing the risk of material contamination. The other horizontal end of the three-way pipe 2 is connected to the sampling cylinder 3. A cylinder connecting shaft 31, made of 304 stainless steel and encased in a transparent acrylic tube, connects the sampling cylinder 3 and the three-way pipe 2. A sampling rod 32 is connected between the output end of the sampling cylinder 3 and the sampling head 33. The sampling rod 32 is positioned within the horizontal section of the three-way pipe 2 by the sampling... The cylinder 3 drives the sliding motion, and the sampling head 33 at the end of the sampling rod 32 has a ring structure and extends to the notch of the three-way pipe 2. The size of the sampling head 33 corresponds to the pipe size of the three-way pipe 2 to form a piston-like motion. When material needs to be sampled, the cylinder lifts and pushes the sampling head 33 to the notch. At this time, the material in the sampling valve body 1 falls from the notch into the pipe of the three-way pipe 2. The sampling cylinder 3 then retracts and drives the material sampled in the pipe to be retrieved and taken out from the vertical pipe of the three-way pipe 2. Real-time random sampling improves the timeliness of sampling and sends it for testing. The three-way pipe 2 is also connected to the air pipe connector 21. The air pipe connector 21 is connected to the air pipe connector 21 and high-pressure airflow is introduced. After sampling, the three-way pipe 2 is back-blown cleaned so that the pipe of the three-way pipe 2 is kept clean during the next sampling to avoid contamination and detection errors.

[0023] In this embodiment, a sampling tube 5 is connected to the vertical pipe of the three-way pipe 2. An HDPE reagent bottle 51 is installed at the bottom of the sampling tube 5. The HDPE reagent bottle 51 is placed in the sampling tube 5. Due to its chemical resistance and good sealing performance, the HDPE reagent bottle 51 can be used to temporarily store samples to prevent them from being contaminated or deteriorated. It can be used to collect various types of samples and safely transport them to the laboratory for further analysis.

[0024] In this embodiment, the sampling sealed box 4 is made of plastic. The sampling sealed box 4 wraps the treatment pipeline of the three-way pipe 2 to form a sealed sampling, ensuring that the sampling process is pollution-free and improving the safety of the sampling environment. The sampling sealed box 4 is also connected to a quick clamp 41 for removing the box cover, which facilitates the removal of the sampling sealed box 4 for cleaning. The sampling sealed box 4 is also equipped with a sampling door 42 for convenient sampling.
