Description

Technical Field

[0001] The utility model relates to the technical field of sampling devices, in particular to a safe sampling device for a cyclonic phenylethylamine high-pressure hydrogenation kettle. Background Art

[0002] The cyclophenylamine high-pressure hydrogenation kettle is a high-pressure equipment used for the cyclophenylamine hydrogenation reaction. It can withstand high pressure and high temperature and is mainly used for the cyclophenylamine hydrogenation reaction. The cyclophenylamine hydrogenation reaction is a process involving specific chemical conditions and catalysts. It can produce high-quality hydrogenated products. During the reaction process, sampling is often required to monitor the hydrogenation reaction process and control product quality. The progress and conversion rate of the hydrogenation reaction can be understood in real time, so as to judge whether the reaction proceeds as expected. Therefore, sampling operation of the reaction is very necessary, which requires a safe sampling device for the cyclophenylamine high-pressure hydrogenation kettle to be used in conjunction with it.

[0003] When using existing high-pressure hydrogenation kettles, the interior of the kettle is often in a high-pressure state. Therefore, when sampling operations are performed, the internal high pressure is often difficult to maintain, which also poses great operational risks. In addition, due to the internal high-pressure state, liquid leakage is likely to occur during sampling, which can easily affect the internal reaction. At the same time, it is not efficient and safe to use. Utility Model Content

[0020] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0021] like Figure 1-Figure 3 As shown, the embodiment of the utility model provides a safe sampling device for a cyclonic phenylethylamine high-pressure hydrogenation reactor, comprising:

[0022] The kettle body 1, the side wall of the kettle body 1 is connected with a sampling tube 2;

[0023] The sampling assembly includes a fixed plate 3 fixedly connected to the side wall of the kettle body 1, the upper surface of the fixed plate 3 is rotatably connected to a threaded rod 4 through a bearing, a nut 5 is threadedly connected to the threaded rod 4, the upper surface of the fixed plate 3 is fixedly connected to a guide rod 6, the outer sliding sleeve of the guide rod 6 is connected to a limit plate 7, the side wall of the limit plate 7 is fixedly connected to the side wall of the nut 5, the nut 5 is fixedly connected to the side wall away from the kettle body 1, the side wall of the connecting plate 8 is fixedly connected to a blocking plate 9, the side wall of the sampling tube 2 is connected to a discharge pipe 10, and the discharge pipe 10 is located at Below the sampling tube 2, a valve is provided at the output end of the discharge tube 10. The discharge tube 10 is used for sampling. The reactants flow out through the discharge tube 10 to complete the sampling. A rubber sealing sleeve 14 is fixedly provided on the upper surface of the sampling tube 2. The blocking plate 9 is located in the rubber sealing sleeve 14. The side wall of the blocking plate 9 fits tightly with the inner wall of the rubber sealing sleeve 14, thereby improving the sealing performance of the equipment and thus enhancing the safety of the later sampling. The side wall of the blocking plate 9 fits tightly with the inner wall of the chute 13. The top of the threaded rod 4 is fixedly connected with a knob for easy operation by the staff.

[0024] The safety component is arranged in the sampling tube 2. The safety component includes a fitting plate 11 fixedly connected to the bottom surface of the blocking plate 9. The inner walls on both sides of the sampling tube 2 are fixedly connected with protective sleeve plates 12. The upper surface of the sampling tube 2 is provided with a slide groove 13. The blocking plate 9 is slidably connected in the slide groove 13. The side wall of the blocking plate 9 is tightly fitted with the inner side walls of the two protective sleeve plates 12. The side wall of the fitting plate 11 is tightly fitted with the side walls of the two protective sleeve plates 12, ensuring that the interior of the kettle body 1 still has good sealing during sampling.

[0025] The detailed working process of this utility model is as follows:

[0026] When in use, when sampling is required, the threaded rod 4 is rotated by the knob. When the threaded rod 4 rotates, the nut 5 will not rotate with the threaded rod 4 under the influence of the guide rod 6 and the limit plate 7, but will be threadedly engaged with the threaded rod 4. Therefore, when the threaded rod 4 rotates, the nut 5 will move up and down along the threaded rod 4, and then drive the blocking plate 9 to move up and down through the connecting plate 8. When sampling is required, the blocking plate 9 is moved downward, and the blocking plate 9 drives the fitting plate 11 to move downward until it is tightly fitted with the inner bottom surface of the sampling tube 2;

[0027] At this time, the blocking plate 9 will divide the interior of the sampling tube 2 into two areas. The part connected to the interior of the kettle body 1 will not be affected, and the blocked part will no longer be affected by the kettle body 1, so the sampling operation can be carried out. The sampling operation can be carried out by opening the valve of the discharge pipe 10. After completion, the blocking plate 9 and the bonding plate 11 can be reset through the threaded rod 4.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
