[0015] Working principle: start the water pump, the output end of the water pump uses the winding reflux pipe to extract the material inside the reactor, and uses the discharge pipe to draw the material into the fixed shell, and then enters the inside of the feed pipe through the fixed shell, and then enters the inside of the reactor. When taking out the material, press the sliding cap downward to compress the reset spring. When the position of the discharge elbow moves to the discharge hole on the limiting ring, the material can enter the inside of the discharge elbow through the discharge hole, so that part of the material can be discharged by using the discharge elbow, so that real-time sampling can be realized. At the same time, because the limiting slide groove cooperates with the slide bar to prevent the sliding cap from rotating, it can prevent the discharge elbow from being misaligned with the discharge hole. When the material enters the fixed shell, it can drive the impeller to rotate. After the impeller rotates, it drives the rotating shaft to rotate. The rotating shaft drives the mounting sleeve to rotate, thereby driving the mixing rod to rotate. The material inside the reactor is stirred by the rotation of the mixing rod. At the same time, the mounting sleeve is used to drive the cleaning mechanism to rotate. After the cleaning mechanism rotates, the material on the inner wall of the reactor can be scraped off, and then the inner wall of the reactor can be cleaned conveniently. When the cleaning mechanism cleans the inside of the reactor, the tightening spring uses its own reaction force to push the limit plate outward, so that the cleaning scraper can be more closely attached to the inner wall of the reactor. When disassembling the sealing cover, first unscrew the discharge pipe and the feeding pipe from the fixed shell, and rotate the rotating frame upward, and then the hanging frame can be driven to move upward under the action of the rotating frame, and then the hanging frame can be rotated down from the locking frame. At this time, the rotating frame is released to drive the sliding ring to move downward under the action of the tension spring, and then the sealing cover can be removed from the reactor by using the lifting rod. When installing the sealing cover, place the bottom of the sealing cover on the top of the reactor, and align the locking frame with the hanging frame. At this time, rotate the rotating frame upward, and then the hanging frame can be moved upward, and then the hanging frame can be locked on the locking frame. At this time, the hanging frame can be tightly locked on the locking frame under the action of the tension spring, so that the sealing cover can be installed on the top of the reactor.

[0016] The present invention provides a real-time sampling and closed reflux device for materials in a kettle, which has the following beneficial effects: 1. The present invention can perform real-time sampling while the material in the kettle is refluxing by cooperating with the reflux mechanism and the sampling mechanism, and has a simple structure without a complicated structure, thereby reducing the sampling cost of the sampling reflux device, and can complete the sampling under a sealed condition, so it will not affect the reaction of the material in the kettle.

[0017] 2. The present invention drives the power generating mechanism to rotate automatically through the reflux mechanism, and can drive the cleaning mechanism to automatically clean the inner wall of the reactor, thereby reducing manual participation in the cleaning of the reactor, saving time and effort, and improving the cleaning efficiency of the reactor. Therefore, the use of the reactor will not be delayed, and the practicality of the reactor is improved. BRIEF DESCRIPTION OF THE DRAWINGS
