When the combination sleeve 603 moves out of the range of the movable pipe 612, the bottom of the installation rod 608 is inserted into the connecting bottom pipe 614, so that the installation rod 608 is pushed up, and the movable pipe 612 and the limiting ring 611 are moved into the installation slot 609, and the push spring 610 is compressed.

When installing the installation rod 608, the installation rod 608 is placed on the bottom of the installation top pipe 601, and the installation rod 608 is pushed up. After the bottom of the installation rod 608 is placed inside the top end of the connecting bottom pipe 614, the installation rod 608 is loosened so that the bottom of the installation rod 608 is inserted into the inside of the connecting bottom pipe 614. At this time, the lever frame 605 is loosened, and the combination sleeve 603 is pushed down under the action of the reset spring 604, and then the combination sleeve 603 is wrapped. At this time, the installation of the installation rod 608 is completed. When the polymerizer 1 needs to be cooled, the automatic valve is opened, and the gas in the pressure stabilizing tank 401 enters the inside of the water tank 11 through the connecting pipe 7. The gas provides gas pressure for the liquid in the water tank 11, so that the liquid in the water tank 11 enters the inside of the rotating sealing ring 304 through the water pipe 13, and quickly enters the inside of the jacket 2 through the lever frame 605 and the through hole 305. Therefore, the polymerizer 1 can be conveniently cooled.

[0035] Working principle: start the air pump 306, the output end of the air pump 306 sprays high-pressure gas, and then the gas is introduced into the inside of the fixed shell 301 through the gas outlet pipe 307. At this time, the impeller 303 is driven to rotate under the action of high-pressure gas, the rotating sleeve 302 is driven to rotate after the impeller 303 rotates, and the jacket 2 is driven to rotate after the rotating sleeve 302 rotates. Therefore, the rotation of the jacket 2 can fully contact with the high-temperature gas, so that the water in the jacket 2 can be cleaned more thoroughly.

[0036] The starting of the air pump 306 can make the high-pressure gas enter the inside of the pressure stabilizing tank 401 through the connecting air pipe 308, and as the gas in the inside of the pressure stabilizing tank 401 is more and more, the piston 406 can be pushed down, and then the inner rod 404 can be driven to move downwards, and after the inner rod 404 moves downwards, the spring one 405 can be compressed, and after the gas in the inside of the pressure stabilizing tank 401 is discharged, the spring one 405 can push the inner rod 404 upwards by using the reaction force of itself, and then the piston 406 can be pushed to move upwards, the gas in the inside of the pressure stabilizing tank 401 is extruded by the piston 406, and then the gas pressure in the inside of the pressure stabilizing tank 401 can be kept, and the function of stabilizing the gas pressure can be realized;

[0037] When the gas enters the inside of the air pipe 501 through the connecting air pipe 308, the gas pressure can push the movable plug 503 to move downwards, and then the connecting rod 504 can be driven to move downwards, and the spring two 506 can be compressed by the movable plug 503, when the movable plug 503 moves to the air groove 507, the gas can enter the inside of the pressure stabilizing tank 401 through the air groove 507, and when there is no gas entering the inside of the air pipe 501, the movable plug 503 can be pushed to move upwards by the spring two 506, so that the movable plug 503 can move out of the range of the air groove 507, and at this time, the gas in the inside of the pressure stabilizing tank 401 cannot be discharged to the outside of the pressure stabilizing tank 401;

[0038] When the electromagnetic valve at the middle of the top end of the pressure stabilizing tank 401 is opened, the gas will enter the inside of the mounting rod 608 through the mounting top pipe 601, and the electric heating wire 613 will be started, which will emit high temperature to heat the gas entering the inside of the mounting rod 608. Since the gas pressure in the inside of the pressure stabilizing tank 401 is large, the hot gas will enter the inside of the tee pipe 615 through the connecting bottom pipe 614. If steam needs to be introduced, the steam will be introduced into the inside of the tee pipe 615 through the steam inlet pipe 617, and will be quickly introduced into the inside of the rotating sealing ring 304 under the driving of the high-pressure and high-temperature gas, and will enter the inside of the jacket 2 through the through hole 305, so that the steam can be quickly introduced into the inside of the whole jacket 2. When the mounting rod 608 is replaced, first, the lever frame 605 is pulled upward, which can drive the sliding column 607 to move upward, so as to drive the combination sleeve 603 to move upward, and then the combination sleeve 603 can compress the return spring 604. When the combination sleeve 603 moves out of the range of the movable pipe 612, since the bottom of the mounting rod 608 is inserted into the inside of the connecting bottom pipe 614, the mounting rod 608 is pushed upward, so as to drive the movable pipe 612 and the limiting ring 611 to move into the inside of the mounting groove 609, and then the push spring 610 is compressed. At this time, the bottom of the mounting rod 608 also moves out of the inside of the connecting bottom pipe 614, so that the mounting rod 608 can be disassembled. When the mounting rod 608 is installed, the mounting rod 608 is placed at the bottom of the mounting top pipe 601, and the mounting rod 608 is pushed upward. After the bottom of the mounting rod 608 is placed in the inside of the top end of the connecting bottom pipe 614, the mounting rod 608 is loosened so that the bottom of the mounting rod 608 is inserted into the inside of the connecting bottom pipe 614.
