[0025] Furthermore, the disassembly mechanism includes two connecting flanges 2, one side of one connecting flange 2 is fixedly connected to one side of the condenser body 1, and the two connecting flanges 2 are connected on one side by a plurality of bolts 4, and the plurality of bolts 4 are equidistantly arranged in a circular array, and one side of the other connecting flange 2 is fixedly connected to a shell sleeve 3, and a glass-lined tube body 5 is installed inside the condenser body 1. When the two connecting flanges 2 are separated, it is convenient to support the position of the shell sleeve 3 later.

[0026] Furthermore, one side of a connecting flange 2 is fixedly connected to two support rods 18, and the two support rods 18 are symmetrically arranged. A slide groove 19 is provided on one side of the support rod 18, and a slide rod 20 is slidably connected inside the slide groove 19. One side of the slide rod 20 is fixedly connected to a guide rod 16, and two guide holes 17 are provided on one side of the other connecting flange 2 corresponding to the two guide rods 16, so that the position of the shell 3 can be supported when the guide holes 17 are sleeved on the guide rods 16.

[0027] Furthermore, the sealing mechanism includes a sealing sleeve 6, one end of the sealing sleeve 6 is fixedly connected to a first connecting pad 8, one side of the first connecting pad 8 is fixedly connected to two clamping blocks 9, the two clamping blocks 9 are symmetrically arranged, the other end of the sealing sleeve 6 is fixedly connected to a second connecting pad 10, one side of the second connecting pad 10 is provided with two clamping grooves 11, the two clamping grooves 11 are adapted to the two clamping blocks 9, so that when the clamping block 9 and the clamping groove 11 are combined, the sealing sleeve 6 is a whole.

[0028] Furthermore, a plurality of positioning holes 7 are provided on one side of the sealing sleeve 6 , and the plurality of positioning holes 7 are equidistantly arranged in a circular array, and a plurality of bolts 4 pass through the plurality of positioning holes 7 , respectively, so as to limit the position of the sealing sleeve 6 .

[0029] Furthermore, the auxiliary mechanism includes a rubber sleeve 12, which is arranged on the outside of the sealing sleeve 6. A sliding hole 13 is opened on one side of the rubber sleeve 12. The rubber sleeve 12 slides on the sealing sleeve 6 through the sliding hole 13. An active cavity 14 is arranged inside the rubber sleeve 12 near the sliding hole 13. An arc rod 15 is placed inside the active cavity 14. When the two connecting flanges 2 are installed and fixed, the arc rod 15 is squeezed, so that the rubber sleeve 12 converges and squeezes the first connecting pad 8 and the second connecting pad 10, thereby ensuring the sealing of the split sealing sleeve 6 when in use.

[0030] Working principle: First, push the guide rod 16 so that one end of the guide rod 16 drives the slide rod 20 to slide inside the slide groove 19, and the other end is embedded in the guide hole 17. When the bolt 4 is just screwed out of a connecting flange 2, pull the shell sleeve 3 so that the shell sleeve 3 drives the guide rod 16 to move away from the condenser body 1, thereby supporting the position of the shell sleeve 3 after disassembly, and facilitating the subsequent installation of the sealing sleeve 6 while keeping the position of the shell sleeve 3 unchanged. At this time, the bolt 4 is still located in the positioning hole 7 on one side of the sealing sleeve 6. Pull the sealing sleeve 6 so that the sealing sleeve 6 drives the first connecting pad 8 to move, so that the block 9 on one side of the first connecting pad 8 and the groove 11 on the second connecting pad 10 are separated inside the rubber sleeve 12, so as to facilitate the staff to pull the first connecting pad 8 at one end of the sealing sleeve 6, so that the first connecting pad 8 drives multiple positioning holes 7 and multiple bolts 4 to separate, so as to disassemble and replace the sealing sleeve 6 without removing the shell sleeve 3.

[0031] Secondly, pull the first connection pad 8 and the second connection pad 10 on the sealing sleeve 6, so that the first connection pad 8 drives the clamping block 9 to be clamped on the second connection pad 10, so that the positioning hole 7 on the sealing sleeve 6 is aligned with the mounting hole on the connecting flange 2, pull the rubber sleeve 12, so that the rubber sleeve 12 slides on the sealing sleeve 6 through the sliding hole 13, until the rubber sleeve 12 moves to and covers the first connection pad 8 and the second connection pad 10, the staff pinches the rubber sleeve 12 by hand, so that the rubber sleeve 12 drives the positioning hole 7 on one side of the sealing sleeve 6 to directly sleeve on the bolt 4 of a connecting flange 2, push the shell sleeve 3, so that the shell sleeve 3 drives the guide rod 16 to drive the sliding rod 20 to slide inside the slide groove 19, at this time, the shell sleeve 3 approaches one side of the condenser body 1, so that multiple mounting holes on one connecting flange 2 are in contact with multiple bolts 4 on another connecting flange 2, and then the bolts 4 are rotated to install the two connecting flanges 2;

[0032] Then, the two connecting flanges 2 gradually approach each other. At this time, one connecting flange 2 squeezes the sealing sleeve 6 and the rubber sleeve 12 toward the other connecting flange 2, so that the arc rod 15 on the rubber sleeve 12 is squeezed and moves inside the movable cavity 14. When the arc rod 15 moves to the top of the movable cavity 14, the arc rod 15 drives the rubber sleeve 12 to stretch upward, so that the rubber sleeve 12 shrinks and squeezes the first connecting pad 8 and the second connecting pad 10. When the two connecting flanges 2 are installed and fixed, the sealing sleeve 6 is used to seal the condenser body 1 and the shell sleeve 3, and the rubber sleeve 12 further seals the connection between the sealing sleeve 6 to ensure the sealing of the split sealing sleeve 6 when in use.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
