Description

Technical Field

[0001] This utility model relates to the technical field of reactor sampling equipment, and in particular to an online sampling device for reactors. Background Technology

[0002] In chemical production processes, monitoring the materials inside the reactor is a crucial step in ensuring product quality and production safety. Currently, reactors are widely used in various chemical processes in industrial applications. However, traditional sampling methods are mostly manual, which is not only complex and cumbersome but also prone to introducing impurities during sampling, affecting the reaction process inside the reactor, and even causing material waste and safety hazards.

[0003] In existing technologies, when sampling from a reactor, a sampling bottle is required. The sampling bottle needs to be connected to the sampling pipe for sampling. The sampling bottle is only supported by the connection point, which is prone to shaking and makes the connection between the two unstable. It is necessary to manually hold the sampling bottle throughout the sampling process to ensure its stability. This may also cause pollution and harm to the environment and operators, resulting in poor practicality. Therefore, this utility model discloses an online sampling device for reactors to solve the problem of needing to manually hold the sampling bottle to keep it stable during the sampling process, thereby improving the convenience of sampling.

On the side wall of component 26, directly above the sampling port mounting plate 14, is a sampling bottle interface 12. The thickness of the sampling bottle interface 12 is the same as the thickness of the sealing cover. A locking ring 13 is installed on the upper edge of the sampling bottle interface 12, which fits into the front end of the short arm of the L-shaped locking buckle 18.

The sampling assembly includes a sampling pipe 9, a first flange 10, a nitrogen valve pipe 11, a sampling port mounting plate 14, a sealing ring 15, a concave mounting base 16, a mounting rod 17, an L-shaped locking buckle 18, a switch buckle 20, a first connecting rod 21, a connecting arm 22, a second connecting rod 23, a vertical guide rod 24, a vertical spring 25, a sampling bottle interface 12, and a locking ring 13, among other components.The sampling pipe 9 is connected to the vessel body 4 via the first flange 10 to ensure a tight seal during sampling. The nitrogen valve pipe 11 is used to fill the sampling pipe 9 with nitrogen to displace the air inside and reduce sampling errors. When sampling is required, the nitrogen valve pipe 11 is first activated via the control box 5 and the operation panel 6 to fill the sampling pipe 9 with nitrogen and displace the air. Then, the sampling bottle interface 12 is aligned with the groove on the sampling port mounting plate 14 and pressed downwards to engage the locking ring 13 with the short arm of the L-shaped locking buckle 18, achieving a sealed connection between the sampling bottle interface 12 and the sampling pipe 9. Next, the valve on the nitrogen valve pipe 11 is slowly opened, and the pressure difference within the vessel body 4 is used to force the material from the vessel body 4 into the sampling bottle. After sampling, close the valve on the nitrogen valve pipe 11, and simultaneously pull the switch buckle 20 upwards to unlock the L-shaped locking buckle 18. Then, remove the sampling bottle interface 12 from the sampling port mounting plate 14 to complete the sampling process. The function of the L-shaped locking buckle 18 and the vertical spring 25: The L-shaped locking buckle 18 is rotatably mounted on the concave mounting base 16 via the mounting rod 17. Vertical guide rods 24 and vertical springs 25 are installed in the sliding grooves 19 on both sides of its long arm. When the sampling bottle interface 12 is connected to the sampling port mounting plate 14, the locking ring 13 pushes the short arm of the L-shaped locking buckle 18 forward, compressing the vertical spring 25. When the locking ring 13 and the front end of the short arm of the L-shaped locking buckle 18 are engaged, the elastic force of the vertical spring 25 keeps the L-shaped locking buckle 18 in a locked state, ensuring a tight seal during the sampling process. When unlocking is required, pull the switch buckle 20 upwards. Through the action of the first connecting rod 21, connecting arm 22, and second connecting rod 23, the long arm of the L-shaped locking buckle 18 moves backward, unlocking the locking ring 13, thus allowing easy removal of the sampling bottle interface 12. The control box 5 and operation panel 6 enable remote control of equipment such as the servo motor 8, achieving intelligent and automated control of the sampling process. This reduces operational difficulty and labor costs, and improves production efficiency.
