Its working principle is as follows: First, the device is placed in a suitable position using four sets of support legs. Then, the air inlet pipe is connected to the upper-level device, and normal operation is then permitted. When bag maintenance or replacement is required, the cover is opened using four sets of second screws. Then, multiple sets of first screws on two sets of discs are removed through the manhole. The first screws can be easily removed by rotating the two sets of discs. The bag is then removed using eight sets of fixing plates for maintenance and replacement. When chamber cleaning is required, four sets of electric cylinders are activated, which in turn move the tray upwards via four sets of pneumatic rods. This moves two sets of scrapers and two sets of sleeves upwards. Then, the reduction motor is activated, which drives the rotating rod, the clamping gear, and the clamping sleeve to rotate. This rotates four sets of support rods and two sets of closing mechanisms, scraping away dust from the inner wall of the chamber. Afterwards, the ball valve is opened, and the dust is discharged from the drain port. Finally, the ball valve is closed after cleaning.
