Description

Technical Field

[0001] This utility model relates to the field of reactor technology, specifically a tubular reactor. Background Technology

[0002] Since their inception, tubular reactors have been widely used in chemical, pharmaceutical, and energy fields due to their advantages such as continuous production, compact structure, and high mass and heat transfer efficiency. Early tubular reactors were mostly simple straight tube structures, increasing the material residence time by extending the tube length to promote the reaction.

[0003] Currently, in existing technologies, tubular reactors typically employ integral or flanged connection structures, which are inconvenient for equipment maintenance and repair. When it is necessary to clean or replace local pipes or internal components, the integral structure requires the entire system to be disassembled, which is cumbersome and consumes a lot of time and manpower. During the disassembly process, it is very easy to cause leakage of residual reaction liquid inside the pipe, resulting in waste of raw materials. Therefore, a tubular reactor is proposed. Utility Model Content

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.

[0030] Please see Figure 1-4 This utility model proposes a tubular reactor, including a bottom plate 1, a vertical rod 2 fixedly connected to the top of the bottom plate 1, a horizontal rod 3 fixedly connected to the right side of the vertical rod 2, threaded grooves 6 on both sides of the horizontal tube 5, a retaining ring 7 threadedly connected to the horizontal tube 5 through the threaded grooves 6, a bend 8 threadedly connected to the retaining ring 7, a retaining block 9 fixedly connected to the outer wall of the bend 8, a closing component 10 for preventing waste of reaction liquid provided on the inner wall of the horizontal tube 5, and an inner tube 11 fixedly connected to the inner wall of the horizontal tube 5 and the bend 8.

[0031] In this embodiment of the utility model, in order to prevent the liquid inside the tube from flowing out and being wasted during maintenance and disassembly, the closing assembly 10 specifically includes a first slide groove 101, a first slider 102, a disc 103, a second slide groove 104, a second slider 105, and a closing plate 106. The first slide groove 101 is opened on the outer wall of the horizontal tube 5. The first slider 102 is slidably connected to the inner wall of the first slide groove 101. The disc 103 is fixedly connected to the top of the first slider 102. The second slide groove 104 is opened on the front of the disc 103. The second slider 105 is slidably connected to the inner wall of the second slide groove 104. The closing plate 106 is fixedly connected to the back of the second slider 105. The closing plate 106 movably passes through the inner tube 11 and moves within the inner wall of the horizontal tube 5.

[0032] Furthermore, there are six horizontal tubes 5, arranged in groups of three, symmetrically positioned around the center of the vertical rod 2. The six horizontal tubes 5 are connected by a bend 8. A switch assembly 12 is provided at the right end of the horizontal tube 5 at the bottom left side of the vertical rod 2. The switch assembly 12 includes a guide block 121, which is fixedly connected to the inner wall of the horizontal tube 5. A movable plate 122 is slidably connected to the inner wall of the guide block 121. A connecting rod 123 is hinged to the front of the movable plate 122 and is hinged to the inner wall of the horizontal tube 5. A tooth 124 is provided on the right side of the connecting rod 123. A pull rod 125 is fixedly connected to the left side of the connecting rod 123. A sliding groove 3 13 is provided on the right side of the horizontal tube 5. The pull rod 125 is slidably connected to the inner wall of the sliding groove 3 13. The movable plate 122, the connecting rod 123, and the tooth 124 are arranged in two groups, symmetrically positioned around the center of the horizontal tube 5, with the two teeth 124 meshing together.

[0033] Furthermore, a fixing bracket 4 is fixedly connected to the front of the crossbar 3, and a horizontal tube 5 is movably connected to the inner wall of the fixing bracket 4. There are two fixing brackets 4, and the two fixing brackets 4 are connected by bolts and nuts.

[0034] In this invention, during use, the horizontal tube 5 is suspended and fixed by the bolt and nut fixing bracket 4. During maintenance, to prevent waste of the reaction liquid, the slider 102 is pushed to slide within the slide groove 101, causing the disc 103 to rotate. When the disc 103 rotates, the slider 105 slides within the slide groove 104, causing the closing plate 106 to move longitudinally. The closing plate 106 slides longitudinally on the inner wall of the horizontal tube 5, blocking the inner tube 11 channel and achieving a blocking effect. The threaded grooves 6 at both ends of the horizontal tube 5 connect the bent tube 8 to the horizontal tube 5 via retaining rings 7. Rotating the retaining rings 7 close to the retaining block 9 separates the horizontal tube 5 from the bent tube 8, enabling quick assembly and disassembly. Then, by unscrewing the bolts and nuts of the fixing bracket 4, a single horizontal tube 5 can be removed for easy equipment maintenance. When the liquid is discharged, the pull rod 125 is pulled, causing it to slide within the slide groove 13, driving the connecting rod 123 to rotate around the hinge point. The teeth 124 on the two connecting rods 123 mesh, causing the movable plate 122 to move outward. The movable plate 122 slides along the guide block 121 to fully open the channel of the inner tube 11 in the horizontal tube 5, thereby realizing the function of liquid discharge.

[0035] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
