[0002] Baghouse dust collectors are highly efficient dust removal devices widely used in industrial production. They purify the air by filtering dust from the air through filter bags. The core component of a baghouse dust collector is the filter bag, and its performance directly affects the dust removal efficiency and the service life of the equipment. Regular inspection and cleaning of the filter bags are crucial for ensuring the normal operation of the equipment during use.

[0003] Traditional baghouse dust collector maintenance typically requires manual opening of the dust collection box and inspection of each filter bag. This method is cumbersome and time-consuming, especially in large dust collectors with numerous filter bags and a huge workload. The installation and removal of the inspection pipe usually requires complex bolt connections or other fixing methods, which is inconvenient and further reduces maintenance efficiency. Therefore, a filter bag inspection and shutdown device for baghouse dust collectors is proposed to solve the above-mentioned problems. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-4 One embodiment of this utility model is: a filter bag inspection and shutdown device for a baghouse dust collector, comprising a dust collection box 1, and further comprising: Door 2 is installed on the front of dust collection box 1; The bracket 3 is fixedly connected to the bottom of the dust collection box 1; The feeding hopper 4 is fixedly connected to the bottom of the dust collection box 1 and is used for feeding materials; Inspection pipe 5 is located above dust collection box 1 and is used for inspecting and maintaining the bag filter. Mounting plate 6 is fixedly connected to the top of the inner wall of dust collection box 1; The snap-fit ​​mechanism 7 is mounted on the mounting plate 6 and is used to snap-fit ​​the inspection pipe 5. The cleaning mechanism 8 is installed inside the inspection pipe 5 and is used to clean the bag filter. The card receiving mechanism 7 includes: The retaining ring 71 is fixedly connected to the through hole opened on the mounting plate 6; The inner wall of the fixing ring 71 is provided with an annular groove; The filter bag 72 is installed at the bottom of the fixing ring 71 and is placed inside the dust collection box 1; The inspection tube 5 is inserted into the inner wall of the fixing ring 71 for ventilation and maintenance of the filter bag 72.

[0017] Card receiving mechanism 7 includes: Multiple locking blocks 73 are movably connected in a groove opened on the outer wall of the inspection pipe 5, and a spring piece 74 is fixedly connected between the groove and the locking block 73 to push the locking block 73 to engage in the arc-shaped groove. The rotating ring 75 is rotatably connected to the outer wall of the fixed ring 71; Multiple protrusions 76 are fixedly connected to the inner wall of the rotating ring 75, and the protrusions 76 slide within the through holes in the inner wall of the fixed ring 71.

[0018] When the protruding side of the protrusion 76 abuts against the outer wall of the locking block 73, it is used to push the locking block 73 to reset.

[0019] The spring 74 is oval in shape, and its two sides abut against the groove and the locking block 73 respectively.

[0020] Cleanup organization 8 includes: The cleaning rod 81 is installed on the inner wall of the inspection pipe 5 via a connecting rod, and the cleaning rod 81 rotates relative to the connecting rod; Turbine blades 82 are fixedly installed on the outer wall of cleaning rod 81; Multiple fixing rods 83 are connected at intervals to the outer wall of the cleaning rod 81, and steel wire ropes 84 are respectively provided at both ends of the fixing rods 83. When the cleaning rod 81 rotates, it drives the steel wire ropes 84 to strike the cloth bag 72.

[0021] The wire rope 84 is hinged to both ends of the fixed rod 83 via hinge blocks, and a striking ball 85 is fixedly connected to the end of the wire rope 84 away from the fixed rod 83 for impacting the cloth bag 72.

[0022] Working principle: When performing maintenance on the bag filter, press the four locking blocks 73 to retract them, and insert the bottom of the inspection tube 5 into the inner wall of the fixing ring 71. At this time, the spring piece 74 inside the locking block 73 is pushed and locked into the annular groove of the fixing ring 71 for quick fixation. Then, ventilation is introduced into the bag 72 through the inspection tube 5, so that the dust inside the bag 72 can be blown into the dust collection box 1 by strong wind, so that the dust can be cleaned and the bag 72 can be inspected. At the same time, when the wind blows, it drives the turbine blades 82 to rotate, which in turn drives the cleaning rod 81 to rotate. At this time, the steel wire rope 84 will be swung up and hit the inner wall of the bag 72 through the striking ball 85, so as to quickly knock off the dust attached to the inside of the bag 72, avoid dust adhering to the bag 72, and improve the cleaning purpose of the bag 72. Meanwhile, after cleaning, rotating the rotating ring 75 will cause the protrusion 76 on the inner side of the rotating ring 75 to rotate, thereby squeezing the locking block 73 and disengaging it from the annular groove, so as to quickly release the restriction of the locking block 73 on the annular groove, achieve the purpose of quickly removing the inspection tube 5, and improve the effect of rapid replacement.
