When the catalyst in the pipe needs to be replaced, the section of the pipe containing the catalyst needs to be disassembled separately. However, due to the limitations imposed by other pipes at both ends of this section, disassembly of the pipe is quite inconvenient. Utility Model Content

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figures 1-4In this embodiment of the present invention, a continuous pyrolysis reactor includes a first connecting pipe 1 and a second connecting pipe, which are connected alternately. The second connecting pipe includes a first connecting pipe 2, a sliding pipe 3, and a second connecting pipe 4. The first connecting pipe 2 and the second connecting pipe 4 are respectively connected to the two ends of the first connecting pipe 1 that are close to each other. The sliding pipe 3 is sleeved on the outer wall of the end of the second connecting pipe 4 that is close to the first connecting pipe 2. The inner walls of the first connecting pipe 2 and the second connecting pipe 4 are both equipped with filling mechanisms. Elastic mechanisms are installed between the two filling mechanisms and in the inner cavity of the sliding pipe 3. Multiple dispersing and mixing plates 5 are fixedly installed on the inner wall of the first connecting pipe 1, and adjacent dispersing and mixing plates 5 are staggered at ninety degrees.

[0015] In this embodiment: First, the reaction raw materials flow in a continuous pipeline composed of connecting pipe 1 and connecting pipe 2. When the raw materials flow in connecting pipe 1, they are continuously cut by multiple dispersing and mixing plates 5 and mixed again after cutting to ensure that the raw materials are fully mixed and the reaction is uniform. After passing through connecting pipe 1, the raw materials enter connecting pipe 2 and come into contact with the filling mechanism inside connecting pipe 2. The catalyst contained in the filling mechanism comes into full contact with the raw materials, and the reaction can then proceed.

[0016] When the catalyst needs to be replaced, the bolts connecting the ends of No. 1 connecting pipe 2 and No. 2 connecting pipe 4 are removed, and then a squeezing force is applied to either No. 1 connecting pipe 2 or No. 2 connecting pipe 4. At this time, the elastic mechanism is compressed, and the end of No. 2 connecting pipe is separated from No. 1 connecting pipe 1. This allows No. 2 connecting pipe and its internal filling mechanism to be disassembled, which facilitates the installation and disassembly of No. 2 connecting pipe.

[0017] Please refer to this carefully. Figure 2 and Figure 3 The filling mechanism includes a container 6 inserted into the inner wall of the first connecting pipe 2 and the second connecting pipe 4. The outer wall of the container 6 is integrally formed with an outwardly protruding docking block 7. The inner walls of the first connecting pipe 2 and the second connecting pipe 4 are provided with sliding grooves for the docking block 7 to slide. The two containers 6 located in the second connecting pipe are both open at their far ends. The filling mechanism includes a crossbar 13 fixedly installed on one end of the inner wall of the container 6 and extending towards the open end. The outer wall of the crossbar 13 is integrally formed with a limiting plate 14 near the open end. A connecting cover 15 is inserted into the inner wall of the open end of the container 6. A filter screen is provided on the connecting cover 15. An inner boss 16 is integrally formed in the center of the connecting cover 15. The end plate of the inner boss 16 is sleeved on the outer wall of the crossbar 13. The limiting plate 14 abuts against one end of the inner boss 16.

[0018] In this embodiment: After the bolts connecting the second connecting pipe to the first connecting pipe 1 are removed, an inward pushing force is applied to the first connecting pipe 2 and the second connecting pipe 4. The first connecting pipe 2 and the second connecting pipe 4 slide relative to each other. At this time, the elastic mechanism is compressed, realizing the separation of the ends of the first connecting pipe 2 and the second connecting pipe 4 from the end of the first connecting pipe 1. The second connecting pipe can then be disassembled. After that, the filling mechanism can be pushed out of the second connecting pipe. Then, by using a wrench and the locking nut threaded on the outer wall of the crossbar 13, the locking nut can be removed. Then, the connecting cover 15 can be opened, the filled catalyst can be poured out and replaced. After replacement, the connecting cover 15 can be reinstalled. Finally, the filling mechanism is inserted into the second connecting pipe, and the second connecting pipe is reconnected to the first connecting pipe 1.

[0019] Please refer to this carefully. Figure 2 and Figure 3 The elastic mechanism includes fixed rods 8 fixedly installed at both ends of the inner wall of the sliding tube 3. Multiple fixed rods 8 are evenly distributed in the circumferential direction. One end of the second connecting tube 4 protrudes and slides circumferentially connected to the outer wall of the fixed rod 8. A first spring 9 is fixedly installed between the protruding end of the second connecting tube 4 and one end of the inner wall of the sliding tube 3. The first spring 9 is sleeved on the outer circumference of the fixed rod 8. The elastic mechanism also includes a connecting rod 10 fixedly installed at one end of a container 6 and a sleeve 11 fixedly installed at one end of another container 6. One end of the connecting rod 10 is inserted into the inner wall of the sleeve 11. A second spring 12 is fixedly connected between one end of the inner wall of the sleeve 11 and one end of the connecting rod 10.

[0020] In this embodiment: when installing or disassembling the No. 2 connecting pipe, by applying a squeezing force to the No. 1 connecting pipe 2 and the No. 2 connecting pipe 4, the two slide relative to each other. At this time, the protrusion at the end of the No. 2 connecting pipe 4 slides along the outer periphery of the fixing rod 8. At this time, the No. 1 spring 9 is compressed. At the same time, the connecting rod 10 moves relative to the sleeve 11 towards its inner wall, and the No. 2 spring 12 is compressed. In this way, the overall length of the No. 2 connecting pipe can be shortened. After the squeezing force is removed, the No. 1 spring 9 and the No. 2 spring 12 return to their original positions, realizing the reset of the No. 2 connecting pipe. It should be noted that sealing rings are installed at all pipe contact points to ensure the airtightness of the connected pipes.

[0021] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
