[0002] In chemical production, it is often necessary to take samples from the reactor multiple times during the reaction process to detect the reaction progress in the reactor or the product quality indicators. The traditional sampling and detection method generally opens the manhole or handhole of the reactor or the sampling valve at the bottom of the reactor to take samples, and then detects them outside the reactor. This sampling and detection method is not only cumbersome and delayed, but also destroys the reaction balance of the system in the reactor, interrupting the normal reaction process, affecting the reaction progress and product quality. Especially in reactions involving corrosive and toxic gases such as bromination synthesis, sampling can easily cause the discharge of dangerous gases, causing environmental pollution or harming the health of operators.

The device can effectively replace manual operation with mechanical operation, saving time and effort.
[0004] However, the sampling and detection device for the bromination reactor of the utility model lacks a liquid level structure, which makes it impossible for external staff to know the volume of the sampling liquid, which easily causes waste of the sampling liquid or insufficient sampling liquid level. In addition, it is inconvenient to return the excess sampling liquid, which seriously affects the sampling and detection efficiency and cannot meet the use requirements. Therefore, a sampling structure for a bromination reactor for dye production is proposed to solve the above problems. Utility Model Content

[0026] When this embodiment is in use, the intermittent motor 11 is started to drive the mounting shell 13 and the piston block 14 to move up and down continuously through the connecting rod 16, and a pressure difference is formed in the bromination reaction kettle body 1 and the shell 2, which causes the liquid in the bromination reaction kettle body 1 to flow into the shell 2, and the liquid in the bromination reaction kettle body 1 is continuously pumped out into the shell 2.
