Description

Technical Field

[0001] This utility model relates to the technical field of reaction vessels, and in particular to a feeding mechanism and its reaction vessel for processing oil displacement activators. Background Technology

[0002] In a broad sense, a reaction vessel is a container for physical or chemical reactions. When in use, solid raw materials are usually fed directly into the reaction vessel through a feeding mechanism, and liquid and gaseous raw materials are fed into the reaction vessel through a feeding pipe. Then, the reaction vessel is heated and stirred to facilitate the reaction of the raw materials.

[0003] In traditional reactors, the feeding structure is typically opened directly to feed raw materials into the reactor. The raw materials enter the reactor directly through the feed inlet. However, some reaction experiments require pressure control. To facilitate sealing the feed inlet and ensure stable pressure, the feed inlet opening is usually small. In this case, an external feed hopper is needed for feeding. However, the feed hopper needs to be held by hand or fixed by other structures, which makes feeding inconvenient. Utility Model Content

A feed inlet is opened at the top of the feeding pipe 2. The cover plate 5 is rotatably arranged inside the feed inlet through a rotating shaft. The positioning assembly 6 is arranged inside the cover plate 5 to restrict the flipping of the cover plate 5 and the movement of the pistons 3. By using multiple pistons 3, the material can be conveyed into the reactor body 1 through the feeding pipe 2 while maintaining a constant internal air pressure. At the same time, the setting of the connecting assembly 4 can not only push the material but also occupy a small space. The setting of the positioning assembly 6 can not only fix the cover plate 5 but also fix the pistons 3, which is convenient for use.

[0031] The connecting assembly 4 includes a push rod 41, a rotating rod 42, a limiting block 43, and a locking member 44. One end of the push rod 41 is fixedly inserted into the piston 3, and the other end is slidably inserted into the feed pipe 2. The rotating rod 42 is rotatably connected to the push rod 41 via a rotating shaft. The cross-sections of the rotating rod 42 and the push rod 41 are circular of the same size. The push rod 41 can push multiple pistons 3 to move. The rotating rod 42 is rotatable, allowing it to rotate for normal pushing during use. When not in use, the rotating rod 42 can be locked inside the locking member 44, thus reducing the overall footprint of the device. The limiting block 43 is fixedly connected to one side of one of the pistons 3, and a limiting groove is formed at the top of the limiting block 43.

The positioning rod 61 can be pulled away from the positioning hole by the pull rod 62, thereby opening the cover plate 5. At this time, the feed inlet is located between the two pistons 3, so that the material to be added can be added into the feed pipe 2, while maintaining the gas pressure inside the reactor. The compression spring 63 is set inside the positioning groove. One end of the compression spring 63 is fixedly connected to the positioning rod 61, and the other end of the compression spring 63 is fixedly connected to the inner wall of the positioning groove.
