[0033] The transmission assembly 82 further includes a lifting assembly 6 for adjusting the lifting of the blade synchronizer 5. The lifting assembly 6 includes an external thread tube 61 slidably arranged on the outer wall of the small-diameter circular cavity 14, radial circular shafts 62 circumferentially and uniformly arranged on the inner wall of the external thread tube 61 and passing through the corresponding lifting side holes 15, a rotating round rod 63 rotatably arranged at the end of the radial circular shaft 62 and inserted into the synchronizing ring groove 55, and a driving screw tube 64 screwed on the outer wall of the external thread tube 61.
[0034] In the degassing device described in this case, a power device 81 is adopted to drive two groups of stirring blades, namely the anchor blade assembly 83 and the blade assembly 84, to rotate, so as to stir the upper and lower parts of the reaction kettle body 9 respectively. And the rotation direction of the blade assembly 84 can be the same as or opposite to that of the anchor blade assembly 83 to adapt to different working conditions.
[0035] Define the rotation direction of the anchor blade connector 2 and the anchor blade assembly 83 as the positive direction. The transmission assembly 82 can conveniently switch the rotation direction of the blade connector 3 and the blade assembly 84 to forward rotation, stop rotation, and reverse rotation: Mode 1, forward rotation of the blade connector 3 and the blade assembly 84: As shown in the Figure 4-5 instruction manual: Under normal conditions, the blade synchronizer 5 is in the high position, that is, the top lock ring 52 is in transmission connection with the upper lock ring 22, so as to realize the same-direction rotation of the anchor blade connector 2, the blade synchronizer 5, and the blade connector 3, and further realize the forward rotation of both the anchor blade assembly 83 and the blade assembly 84; Mode 2, stop rotation: Rotate the driving screw tube 64 to make the lifting assembly 6 and the blade synchronizer 5 in the middle position, that is, make the top lock ring 52 disengage from the upper lock ring 22, and the bottom lock ring 53 disengage from the lower lock ring 422. At this time, the blade connector 3 and the blade connection assembly 84 lose power and start to stop rotating; Mode 3, reverse rotation of the blade connector 3 and the blade assembly 84: As shown in the Figure 3 instruction manual: It should be noted that due to the transmission connection relationship of the upper bevel gear 21, the intermediate gear 41, and the annular bevel gear 421, the reverse rotation assembly 42 always rotates in the reverse direction; Rotate the driving screw tube 64 to drive the external thread tube 61, the radial circular shaft 62, and the rotating round rod 63 to move downward, so that the lifting assembly 6 and the blade synchronizer 5 are in the low position; The rotating round rod 63 acts on the synchronous ring groove 55 to drive the blade synchronizer 5 to move downward. The top locking ring 52 is disengaged from the upper locking ring 22, and the bottom locking ring 53 is in driving connection with the lower locking ring 422. The blade synchronizer 5 starts to rotate in the reverse direction; Since the transmission key 56 and the transmission key hole 313 always maintain a transmission connection relationship, the blade connector 3 and the blade assembly 84 start to rotate in the reverse direction.
[0036] It should be noted that the side wall and the lower bottom of the bearing circular cavity 16 are detachably arranged. After the side wall and the lower bottom of the bearing circular cavity 16 are disassembled, the blade connector 3 can be removed, and then the bearing rollers 32 can be quickly replaced: Rotate the dialing upper rod 334 to drive the annular base 331, the limit arc groove 332, and the arc-shaped chuck 335 to rotate against the damping of the return compression spring 333. The semi-circular round holes 34 on the arc-shaped chuck 335 are separated from the semi-circular round holes 34 on the longitudinal cut 314. At this time, all the bearing rollers 32 can be conveniently removed for maintenance and replacement. After the replacement is completed, the roller fixture 33 is reset.
[0037] It should be noted that the blade connector 3 can also limit the rotational freedom of the roller fixture 33: A stop collar 35 that abuts against the arc-shaped chuck 335 is provided below any arc-shaped blind hole 315. By fixing the stop collar 35 to the arc-shaped blind hole 315 with a stop bolt 35, the roller fixture 33 can be prevented from unnecessary rotation, causing the bearing rollers 32 to come out.
[0038] It should be noted that an easy-to-hold labor-saving lever is fixedly connected to the outside of the driving screw tube 64 along the radial direction. By rotating the labor-saving lever, the driving screw tube 64 can be driven to rotate.
