As shown in fig. 9, in order to prevent the movable rod 34 from moving upwards along the movable cavity 33 when the filter bag 2 is partially blocked, and prevent the movable rod 34 from triggering the pulse mechanism to work when the filter bag 2 is partially blocked, the movable rod 34 is further sleeved with a spring in the movable cavity 33, the spring is pressed and accumulated when the movable rod 34 moves upwards, when the filter bag 2 is partially blocked, the space in the adjusting cavity 311 is compressed, and the space in the adjusting cavity 311 is also compressed due to the elastic force of the spring, so that when the space in the adjusting cavity 311 is compressed, the other support rods 32 are pushed to extend outwards from the adjusting cavity 311 until all sides of the filter bag 2 are seriously blocked, the movable rod 34 is pushed to move upwards against the elastic force of the spring, and trigger the pulse mechanism to work.
Because the whole height of the filter bag 2 is higher, in order to enable the folds on the filter bag 2 to be unfolded and folded smoothly, the connecting shaft 3 is also sleeved with the guide piece 35, the guide piece 35 can be annular, the periphery side of the guide piece 35 is uniformly connected with a plurality of guide rods 36, one end of each guide rod 36 is in sliding connection with the guide piece 35 along the radial direction of the guide piece 35, the other end of each guide rod 36 is in one-to-one correspondence connection with each rib 21, and each guide rod 36 extends synchronously along with each support rod 32.
The bag type pulse dust collector provided by the embodiment only triggers the pulse mechanism to clean the filter bag 2 when the sides of the filter bag 2 are seriously blocked, so that the cleaning frequency of the bag type pulse dust collector in the working process is reduced, and the working efficiency of the dust collector is improved.
In addition, when pulse mechanism carries out the clearance to filter bag 2, pulse mechanism blows compressed gas to filter bag 2 in, makes filter bag 2 suddenly expand, and under the effect of reverse air current, the dust that adheres to on filter bag 2 surface breaks away from filter bag 2 rapidly and falls into ash bucket 12, so pulse mechanism when carrying out the deashing to a certain filter bag 2, the dust is more easy to adhere to on other filter bags 2 of its week side, influences the normal work of other filter bags 2 of week side, leads to the cleaning effect not ideal.
In other embodiments, when a certain filter bag 2 is subjected to ash removal operation, the folds of the part, opposite to the filter bag 2, of the surrounding filter bag 2 can be folded, so that the contact area between the peripheral filter bag 2 and dust is reduced, and the influence on the peripheral filter bag 2 is reduced when the filter bag 2 is subjected to ash removal.
As shown in fig. 5 and 6, each rib 21 in the filter bag 2 is connected with a sliding block 22 at the opening end of the filter bag 2, a sliding groove is arranged on a mounting plate 23, the sliding blocks 22 slide in a manner of being attached to the sliding groove, the sliding blocks 22 on any longitudinally adjacent and transversely adjacent filter bags 2 are connected through a connecting structure, the connecting structure comprises a connecting rod 24 and a connecting cylinder 25, the connecting rod 24 and the connecting cylinder 25 are respectively connected with the two sliding blocks 22, the connecting rod 24 stretches into the connecting cylinder 25, a circular connecting piece 26 is fixed in the connecting cylinder 25, the side edge of the connecting piece 26 slides in a manner of being attached to the side wall of the connecting cylinder 25, a plurality of through holes are formed in the connecting piece 26, when the two sliding blocks 22 generate relative movement with smaller relative speed, namely, when the surface of the filter bag 2 is contacted with dust-containing gas, the sliding blocks 22 slowly move along with the supporting rod 32 in a direction of approaching to the connecting shaft 3, under the action of the through holes on the connecting piece 26, the air flow in the two side cavities of the connecting piece 26 slowly convects, and the connecting rod 24 slides relatively to the connecting cylinder 25;
When two sliders 22 produce relative motion with higher relative speed, namely when the pulse mechanism carries out the deashing to a certain filter bag 2, filter bag 2 rapid expansion, rib 21 promotes slider 22 removal fast along with the expansion of filter bag 2, because the aperture setting of the through-hole on connection piece 26 is less, two sliders 22 are when rapid relative movement, the air current of connecting cylinder 25 in the cavity of connection piece 26 both sides comes not to take place relative circulation, the slider 22 that links to each other with filter bag 2 in the clearance promotes its transversely adjacent or vertically adjacent slider 22 removal through connection structure fast, adjacent slider 22 drives the fold folding on the side of filter bag 2 adjacent with filter bag 2 in the clearance when moving, in order to when a certain filter bag 2 carries out the pulse dedusting operation, adjacent filter bag 2 is folded towards the part of this filter bag 2, the influence that filter bag 2 produced adjacent filter bag 2 in the clearance process has been reduced, improve the clearance effect to filter bag 2.
