[0027] In the specific implementation, during the use of the dust collecting device, in order to quickly combine and move the dust collecting shell 1 and the mounting seat 8 to a designated position, since the dust collecting shell 1 is connected with the limiting plate 911, the dust collecting shell 1 is first hoisted to make the limiting plate 911 abut against the mounting seat 8, then the servo motor 901 is started to drive the first bevel gear 902 to rotate, and since the first bevel gear 902 and the second bevel gear 903 are in meshing connection, the rotation of the first bevel gear 902 drives the second bevel gear 903 to rotate, and the rotation of the second bevel gear 903 drives the threaded column 904 to rotate in the positive direction, at this time, the threaded column 904 is limited by the support seat 905;

[0028] Then the rotation of the threaded column 904 drives the threaded seat 906 to drive the lifting seat 907 to move upwards, since the lifting seat 907 and the guide rod 908 are in rotary connection, the upward movement of the lifting seat 907 drives the guide rod 908 to rotate, at this time, the included angle between the guide rod 908 and the lifting seat 907 changes, thereby generating a pushing force on the sliding plate 909, so that the sliding plate 909 moves away from each other along the fixed column 912, and the movement of the sliding plate 909 extrudes the spring 913 to cause the spring 913 to deform, until the sliding plate 909 drives the fixed pin 910 to abut against the limiting plate 911, thereby fixing the dust collecting shell 1 to prevent it from moving randomly, and the combination of the dust collecting shell 1 and the mounting seat 8 can be completed without repeatedly rotating a plurality of bolts, which saves time and facilitates subsequent disassembly;

[0029] When the dust collecting shell 1 needs to be disassembled for maintenance, the servo motor 901 is started to drive the threaded column 904 to rotate in the reverse direction, then the reverse rotation of the threaded column 904 drives the threaded seat 906 to drive the lifting seat 907 to move downwards, at this time, the included angle between the lifting seat 907 and the guide rod 908 changes, thereby making the sliding plate 909 move towards each other, and at this time, the spring 913 resets to assist the movement of the sliding plate 909, until the fixed pin 910 is disconnected from the limiting plate 911, thereby canceling the fixation of the limiting plate 911, at this time, the dust collecting shell 1 is sent to a designated position for wide-range maintenance, so that the bag dust collector does not need to be maintained near the mounting seat 8 using a portable tool, and finally during the use of the dust collecting device, the dust collecting device plays a role of facilitating quick combination and disassembly and maintenance.

[0031] In specific implementation, in the use process of the dust collecting device, in order to improve the dust filtering effect, when the flue gas filtered by the filter bag 3 passes through the air outlet pipe 5, the flue gas first enters the filter cylinder 1001 and contacts the filter screen plate 1005, and then the flue gas is filtered again through the filter screen plate 1005, and then the driving motor 1003 on the cover plate 1002 is started, because the driving motor 1003 is connected with the rotating column 1004, the driving motor 1003 is started to drive the rotating column 1004 to rotate, and then the rotating column 1004 rotates to drive the filter screen plate 1005 to rotate, so that the filter screen plate 1005 is no longer stationary, and the filter screen plate 1005 in contact with the flue gas is always changing, thereby improving the dust filtering effect in the flue gas and reducing the dust content in the flue gas, so that the dust collecting device plays a role in facilitating the improvement of the filtering effect when in use.

[0032] In summary, when the combined dust collecting device is used, the flue gas is first introduced into the dust collector shell 1 through the air inlet pipe 2, and then the flue gas is filtered and dedusted by the filter bag 3, and then the flue gas is discharged through the air outlet pipe 5 after the dedusting of the flue gas is completed; when the dust on the outer surface of the filter bag 3 accumulates and becomes thicker, the air pressure becomes larger, and the compressed air is sprayed to the filter bag 3 through the air injection assembly 4, so that the dust on the outer surface of the filter bag 3 is washed off to the dust discharge pipe 6, and then the valve 7 is opened to guide the dust out, and a differential pressure transmitter is arranged at the inlet and outlet thereof, and then the differential pressure inside the bag dust collector is monitored, which is the prior art and will not be described in detail here, the combination of the dust collector shell 1 and the mounting seat 8 is quickly completed through the fixing mechanism 9, the dust collecting device is conveniently disassembled by workers and sent to a designated place for overhaul, the flue gas is filtered again through the auxiliary mechanism 10, thereby improving the dust filtering effect in the flue gas and reducing the dust content in the flue gas, and the contents not described in detail in the description belong to the prior art known to those skilled in the art.

[0033] Although the utility model has been explained in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacement to part of the technical features, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
