[0034] The working principle of this utility model:

[0035] When in use, the cover body 2 is placed on the upper end of the tank body 1, and at the same time, the six positioning blocks 61 fixedly connected to the lower end of the cover body 2 are aligned and inserted into the six docking grooves 7 for docking, and then the electric cylinder 522 is controlled to start, and the output end of the electric cylinder 522 moves to the left in the stroke groove 9, while driving the push block 524 to move, and the push block 524 is used to push the connecting piece 8. At the same time, the output end of the electric cylinder 522 moves in the stroke groove 9 to ensure that it is not restricted, and the connecting piece 8 is pushed to drive the turntable 511 to rotate. When the turntable 511 rotates, it drives the six support blocks 512 to rotate, and when the support block 512 rotates, it drives the six The wedge blocks 513 are inserted into the six extrusion grooves 62 to squeeze the inner walls of the extrusion grooves 62, so that the positioning blocks 61 are squeezed to pull the cover body 2 downward, so that the cover body 2 is pulled downward to cooperate with the tank body 1 to squeeze the sealing gasket 4 to seal. When the seal is released and the cover body 2 is removed, the pulling block 523 is pulled to the right by controlling the electric cylinder 522, so that the pulling block 523 squeezes the connecting member 8 to the right, and the connecting member 8 drives the turntable 511 to rotate in the opposite direction. The rotation of the turntable 511 drives the wedge block 513 to rotate through the support block 512, so that the wedge block 513 rotates out of the extrusion groove 62, releasing the downward pressure on the cover body 2, and then the cover body 2 can be removed upward.

[0036] To sum up: the sealing device of the reactor solves the problem of the existing reactor in which the lid is sealed and fixed to the tank body by setting the tank body 1, the cover body 2, the stirring device 3, the sealing gasket 4, the sealing device 5, the clamping assembly 51, the turntable 511, the support block 512, the wedge block 513, the pushing assembly 52, the support member 521, the electric cylinder 522, the pulling block 523, the pushing block 524, the docking assembly 6, the positioning block 61, the extrusion groove 62, the docking groove 7, the connecting member 8 and the stroke groove 9. When the lid body is sealed and fixed to the tank body, multiple bolts are usually used in combination with a sealing gasket for sealing and fixing. In this way, it is necessary to use tools to repeatedly tighten the bolts for sealing and fixing during fixing and subsequent disassembly, which not only consumes physical strength of the personnel, but also affects the efficiency of its sealing and fixing and subsequent disassembly work.
