[0024] Please refer to Figures 1-8, A tube reactor that is convenient for disassembly according to the present utility model includes a bottom plate 1. Two sets of vertical plates 2 are symmetrically and fixedly installed at the top of the bottom plate 1. Three sets of obliquely arranged grooves 3 are equidistantly provided on the two sets of vertical plates 2. Two sets of limiting rings 7 are symmetrically and fixedly sleeved on the outer walls of the first reaction tube 4, the second reaction tube 5, and the third reaction tube 6. The first reaction tube 4, the second reaction tube 5, and the third reaction tube 6 are all equidistantly clamped on the two sets of vertical plates 2 through cooperation with the obliquely arranged grooves 3. The outer sides of the two sets of limiting rings 7 on the first reaction tube 4, the second reaction tube 5, and the third reaction tube 6 are respectively in contact with the inner sides of the two sets of vertical plates 2. Threads are provided on the inner walls of the input end of the first reaction tube 4 and the output end of the third reaction tube 6. T-shaped docking sleeves 10 are fixedly communicated on the feed pipe 8 and the discharge pipe 9. The feed pipe 8 is installed at the input end of the first reaction tube 4 through the cooperation of the T-shaped docking sleeve 10 and the thread. The discharge pipe 9 is installed at the output end of the third reaction tube 6 through the cooperation of the T-shaped docking sleeve 10 and the thread. Two sets of hydraulic telescopic rods 11 are respectively fixedly installed on the inner sides of the two sets of vertical plates 2. Variable diameter sleeves 13 are fixedly communicated at the ports on both sides of the two sets of arc-shaped connecting pipes 12. Docking circular grooves are provided in a matching manner in the four sets of variable diameter sleeves 13. Inner sealing gaskets 15 are arranged in each docking circular groove. Two sets of sealing rings 16 are sleeved on the left outer wall of the first reaction tube 4, the outer walls on both sides of the second reaction tube 5, and the right outer wall of the third reaction tube 6. The two sets of variable diameter sleeves 13 on one set of arc-shaped connecting pipes 12 are respectively sleeved on the left sides of the first reaction tube 4 and the second reaction tube 5 through the cooperation of the docking circular grooves. The two sets of variable diameter sleeves 13 on the other set of arc-shaped connecting pipes 12 are respectively sleeved on the right sides of the second reaction tube 5 and the third reaction tube 6 through the cooperation of the docking circular grooves. Connecting plates 14 are fixedly connected between the two sets of variable diameter sleeves 13 on the left side and between the two sets of variable diameter sleeves 13 on the right side. The output ends of the two sets of hydraulic telescopic rods 11 are respectively fixedly connected to the inner sides of the two sets of connecting plates 14;In use, initially, the hydraulic telescopic rod 11 is in a retracted state. The hydraulic telescopic rod 11 pulls the arc-shaped connecting pipe 12 through the connecting plate 14 to ensure the fixed position of the arc-shaped connecting pipe 12, so that the arc-shaped connecting pipe 12 is docked with the first reaction pipe 4, the second reaction pipe 5, and the third reaction pipe 6 through the reducing sleeve 13. After the docking is completed, the sealing ring 16 is squeezed against the inner wall of the reducing sleeve 13, and the left end of the first reaction pipe 4, both ends of the second reaction pipe 5, and the right end of the third reaction pipe 6 squeeze the inner sealing gasket 15. Then, through the inner sealing gasket 15 and the sealing ring 16, the sealing performance of the docking is ensured to prevent leakage. The feed pipe 8 and the discharge pipe 9 are installed on the first reaction pipe 4 and the third reaction pipe 6 by means of screwing through the T-shaped docking sleeve 10, which is convenient for disassembly and assembly. When the reaction pipes need to be replaced or cleaned, by starting the hydraulic telescopic rod 11, the hydraulic telescopic rod 11 pushes the arc-shaped connecting pipe 12 to move outward through the connecting plate 14, so that the reducing sleeve 13 is disengaged from the reaction pipes. The limiting ring 7 plays a limiting role to prevent the reaction pipes from swaying left and right during the disengagement process of the reducing sleeve 13. After the reducing sleeve 13 is disengaged from the docking, the first reaction pipe 4, the second reaction pipe 5, and the third reaction pipe 6 can be taken out from the inclined placement groove 3 for replacement or cleaning, so that the disassembly and assembly of the reaction pipes can be more convenient, which is convenient for maintenance personnel to replace or clean and brings convenience to the maintenance personnel.

[0025] Card positioning mechanisms are arranged in the three inclined placement grooves 3 on the two groups of vertical plates 2. The card positioning mechanism includes a T-shaped cylindrical top head 17. A blind hole is vertically arranged on the upper wall of the inclined placement groove 3, and a sliding hole communicating with the blind hole is provided on the upper wall of the inclined placement groove 3. The upper wall of the inclined placement groove 3 is slidably provided with a T-shaped cylindrical top head 17 through the cooperation of the blind hole and the sliding hole. The bottom end of the T-shaped cylindrical top head 17 is spherical. A spring 18 is fixedly connected in the blind hole, and the bottom end of the spring 18 is fixedly connected with the top end of the T-shaped cylindrical top head 17. In use, when the first reaction pipe 4, the second reaction pipe 5, and the third reaction pipe 6 are installed on the vertical plate 2 through the inclined placement groove 3, the reaction pipes will squeeze the T-shaped cylindrical top head 17, and then the spring 18 will be compressed. When the first reaction pipe 4, the second reaction pipe 5, and the third reaction pipe 6 are placed well, the spring 18 will start to rebound and reset. The spring 18 pushes the T-shaped cylindrical top head 17 to slide outward, so that the T-shaped cylindrical top head 17 abuts against the outer wall of the reaction pipe, and the reaction pipe is clamped in the inclined placement groove 3, improving the firmness of the reaction pipe installation. When disassembling, the reaction pipe is taken out along the inclined placement groove 3, and the reaction pipe will squeeze the T-shaped cylindrical top head 17 again, thus not affecting the disassembly of the reaction pipe.

[0026] Buffer soft pads 19 are fixedly connected to the arc surfaces at the bottoms of the multiple groups of inclined placement grooves 3. By providing the buffer soft pads 19, it can prevent the reaction pipes from colliding with the bottom of the inclined placement grooves 3 during installation and play a buffering role.

[0027] Both of the two sets of T-shaped docking sleeves 10 are sleeved with outer gaskets 20. By providing the outer gaskets 20, the T-shaped docking sleeves 10 can be more closely fitted after screwing, improving the sealing performance.

[0028] Anti-slip rubber pads 21 are fixedly connected to the four corners at the bottom end of the bottom plate 1. By providing the anti-slip rubber pads 21, the situation that the bottom plate 1 slips with the placement position can be effectively avoided, improving the stability of the placement.

[0029] Rounded corners 22 are provided at the lower edges of the front ends of multiple groups of the inclined placement grooves 3. By providing the rounded corners 22, the lower edges of the front ends of the inclined placement grooves 3 can be made smoother, preventing the reaction tube from being bruised during disassembly and assembly.

[0030] For a tube reactor of the present utility model that is convenient to disassemble, its working principle is as follows. During use, initially, the hydraulic telescopic rod 11 is in a retracted state. The hydraulic telescopic rod 11 pulls the arc-shaped connecting pipe 12 through the connecting plate 14 to ensure the fixed position of the arc-shaped connecting pipe 12, so that the arc-shaped connecting pipe 12 is docked with the first reaction tube 4, the second reaction tube 5, and the third reaction tube 6 through the reduced-diameter sleeve 13. After docking, the sealing ring 16 is extruded against the inner wall of the reduced-diameter sleeve 13, and the left end of the first reaction tube 4, both ends of the second reaction tube 5, and the right end of the third reaction tube 6 extrude the inner gasket 15. Then, through the inner gasket 15 and the sealing ring 16, the sealing performance of the docking is ensured to prevent leakage. The feed pipe 8 and the discharge pipe 9 are installed on the first reaction tube 4 and the third reaction tube 6 by screwing through the T-shaped docking sleeves 10, which is convenient for disassembly and assembly. When the reaction tube needs to be replaced or cleaned, by starting the hydraulic telescopic rod 11, the hydraulic telescopic rod 11 pushes the arc-shaped connecting pipe 12 to move outward through the connecting plate 14, so that the reduced-diameter sleeve 13 is disengaged from the reaction tube. The limiting ring 7 plays a limiting role to prevent the reaction tube from swaying left and right during the disengagement process of the reduced-diameter sleeve 13. After the reduced-diameter sleeve 13 is disengaged from the docking, the first reaction tube 4, the second reaction tube 5, and the third reaction tube 6 can be taken out from the inclined placement grooves 3 for replacement or cleaning. When the first reaction tube 4, the second reaction tube 5, and the third reaction tube 6 are installed on the vertical plate 2 through the inclined placement grooves 3, they will extrude the T-shaped cylindrical head 17, so that the spring 18 is compressed. When the first reaction tube 4, the second reaction tube 5, and the third reaction tube 6 are placed properly, the spring 18 starts to rebound and reset. The spring 18 pushes the T-shaped cylindrical head 17 to slide outward, so that the T-shaped cylindrical head 17 abuts against the outer wall of the reaction tube, clamping the reaction tube in the inclined placement grooves 3 and improving the firmness of the reaction tube installation.
