As shown in fig. 7, the angle of the circumferential extension of the twist fit groove 44 on the mounting ring 13 is 50 ° -55 °, and the rotation effect and the subsequent scraping effect of the movable rod 16 are ensured by the limit of the twist fit groove 44 to the twist post 45 and the dislocation ring 14.
When furnace gas enters the air inlet pipe 32 through the dust collection box 31, the negative pressure at the end of the air outlet pipe 33 pumps the upper part into negative pressure, so that the bottom furnace gas is discharged after being filtered by the cloth bag 2, at the same time, dust with water vapor adheres to the outside of the cloth bag 2, the whole weight of the cloth bag 2 gradually becomes heavy, so that the cloth bag 2, the mounting ring 13 and the dislocation ring 14 sink, in the sinking process of the mounting ring 13 and the dislocation ring 14, when the mounting ring 13 and the dislocation ring 14 sink together, because the dislocation ring 14 is fixed with the torsion column 45, so that the torsion column 45 is limited by the power storage side wall 53 of the torsion groove 46, the torsion column 45 drives the dislocation ring 14 to rotate anticlockwise along with the power storage groove 55, and when the dislocation ring 14 rotates anticlockwise, the movable rod 16 is driven to rotate, so that the movable rod 16 gradually approaches the fixed rod 15, and gradually takes an overlapped form, at the moment, the cloth bag 2 loses the original support of the position of the inner movable rod 16, starts to move towards the dislocation ring 14, and the dislocation ring 14 rotates, and the torsion block 43 outside the torsion column 14 and the torsion spring impacts the torsion spring 48 on the torsion ring 14, so that the torsion column 16 slides on the power storage groove 48, and the torsion spring 14, and the torsion spring returns to move, so that the power storage ring 14 is quickly drives the torsion column 16, and the torsion column 13 and the torsion spring 14 to move quickly, and the torsion ring 14, and the torsion spring 14, and the torsion column 16 returns to the power storage groove, and the power storage groove 48, and the power storage groove 14 returns to the power storage groove 14, the mounting ring 13 vibrates for the first time, so that the auxiliary mud block falls, and after the vibration, the vibration matching block 41 on the mounting ring 13 is twisted inside the vibration matching groove 42 to a certain extent, at the moment, the mounting ring 13 drives the cloth bag 2 to twist as shown in fig. 11, the mud block is driven by the cloth bag 2 to twist and continuously falls, at the moment, the reset spring 47 pulls the mounting ring 13 to reset and rise, meanwhile, the torsion column 45 slides inside the reset groove 57, the mounting ring 13 impacts the fixing frame 11 after reaching the top, the torsion column 45 reaches the position of the reset dead point 58 after reaching the top, and because the position of the reset dead point 58 deviates from the position of the power storage vertex 51 to the side wall 53 of the power storage vertex, the subsequent torsion column 45 cannot be clamped on one side of the reset groove 57, the mounting ring 13 vibrates the mud block again due to the second vibration, the auxiliary falling is realized, after the mounting ring 13 impacts the fixing ring 11, the switch of the pulse group 34 is triggered, the pulse group 34 blows the cloth bag 2, and the mud block is assisted to fall again.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
