[0002] In the production equipment, the material composition in the fluorination reactor is complex. In addition to the main product, there are also unreacted fluorosulfonic acid impurity products. In order to ensure the safety of sampling and reduce corrosion to the analytical instruments, an alkaline washing sampling device is required. It can absorb the acidic substances in the sampled samples and release the pressure on the sampling pipeline to reduce the sampling risk.

[0003] After searching the prior art, the patent with patent announcement number CN208999167U discloses a sampling device for the middle of the fluorination reactor reaction. The sampling device is placed outside the sampling tube through an external flange, and the diameter is larger than the diameter of the sampling tube mouth. The end of the tube plug away from the sampling tube mouth is fixedly connected with a rotating handle, and a clamping mechanism is connected to the tube plug. When sampling, the sample liquid will not flow out, avoiding burns to the operator. The sampling device has the following problems when in use;

[0004] When the sampling device samples the product of the fluorination reactor, since the product contains a large amount of fluorosulfonic acid impurity products, it is necessary to use sodium hydroxide to implement alkaline washing operation, so as to remove the fluorosulfonic acid before sampling. During the alkaline washing process, the position is fixed, so it is difficult for the fluorosulfonic acid and sodium hydroxide to mix and react quickly during sampling, resulting in a significant reduction in sampling efficiency. Therefore, a fluorination reactor sampling device is provided. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] As attached Figure 1-7 A fluorination reactor sampling device is shown, and a linkage sampling assembly is arranged on the fluorination reactor sampling device. The arrangement of the linkage sampling assembly can realize reciprocating mixed alkali washing, and quickly complete the sampling operation after alkali washing, which not only improves the sampling safety, but also greatly improves the sampling efficiency. The specific structure of the linkage sampling assembly is arranged as follows:

[0025] In this embodiment, as shown in the attached Figure 1-5 As shown, the linked sampling assembly includes a collar block 4 installed on the outer wall of the alkali cleaning pipe 1 and located on one side of the liquid inlet electric valve 3, and a rotating shaft 5 is fixedly connected to one side of the collar block 4 and near its bottom end; the outer wall of the rotating shaft 5 is rotatably connected to a sleeve support plate 6 through a bearing, and the sleeve support plate 6 is used to support the rotation of the rotating shaft 5, one end of the rotating shaft 5 extends to the outside of the sleeve support plate 6 and is coaxially connected to a reduction motor 7, and a support block 8 for supporting the reduction motor 7 is installed on one side of the sleeve support plate 6.

[0026] When the fluorination reactor sampling device of the present technical solution is used for sampling, the operator first inserts the expansion bolt into the mounting hole 9 to fix the mounting hole 9 at the designated mounting position, inserts the bolt into the hole position of the reactor docking sleeve 12, docks the reactor docking sleeve 12 with the fluorination reactor discharge pipe, and uses the bolt to lock the reactor docking sleeve 12, then opens the liquid inlet electric valve 3 to inject sodium hydroxide into the alkali washing pipe 1, closes the liquid inlet electric valve 3, opens the fluorination reactor to discharge the solution, injects it into the reactor docking sleeve 12, enters the hose 11 through the reactor docking sleeve 12, and is transported to the fixed sleeve block 10 by the hose 11 before being discharged;

The sampling conduit 13 pours the alkali-washed solution into the lower row electric valve 14 and then transports it to the sampling tube 15, completing the solution output operation.

[0032] According to the upper structure, when the alkali cleaning pipe 1 reciprocates, the alkali cleaning pipe 1 can contact the inner wall of the rubber strip 20, and at the same time, the sleeve support plate 6 provides support force for the support plate 17, and the inclined support plate 18 on the inner wall of the support plate 17 can provide stable support, and the support plate 17 realizes vertical support for the connecting support block 19, and the connecting support block 19 provides stable support for the rubber strip 20.
