A relatively large amount of powder is fed in. The top of the feeding hopper 6 is fixedly connected to a dust cover 7 to shield the material and prevent dust from scattering. A dust collection component is installed on the top of the dust cover 7 to absorb and treat the dust. The bottom of the cylinder 1 is fixedly connected to a discharge pipe 9 on the side away from the feeding hopper 6. The bottom end of the discharge pipe 9 is fixedly connected to a telescopic pipe 16. The bottom end of the telescopic pipe 16 is fixedly connected to an end pipe 17. The limestone powder is finally discharged from the end pipe 17 into the desulfurization system.

[0031] Reference Figure 1 and Figure 3 The dust collection assembly includes a dust collection box 10, a fan 11, an air duct 12, a suction head 13, and a filter 14. The dust collection box 10 is fixedly connected to the top of the dust cover 7 and is used to store dust. An air duct 12 is fixedly connected to one side of the dust collection box 10 for conveying dust. The bottom end of the air duct 12 passes through the inner wall of the dust cover 7 and is fixedly connected to the suction head 13 to facilitate the concentrated suction of dust. A fan 11 is fixedly installed on the other side of the dust collection box 10 to attract dust. A filter 14 is fixedly installed on one side inside the dust collection box 10 by bolts to filter and block the sucked-in dust in the dust collection box 10.

[0032] Reference Figure 3 The input end of the fan 11 is connected to the inside of the dust collection box 10. After the fan 11 is started, it can suck the dust in the dust cover 7 into the dust collection box 10.

[0033] Reference Figure 3 A vibration motor 15 is fixedly installed on the side of the filter screen 14 near the fan 11. By periodically starting the vibration motor 15, dust can be prevented from clogging the mesh of the filter screen 14, ensuring the continuous operation of the dust collection component.

[0034] Reference Figure 4The adjustment assembly includes a connecting frame 18, a connecting rod 19, a nut 20, a handle bolt 21, and several locking holes 22. The connecting frame 18 is fixedly connected to the bottom of the discharge pipe 9. The bottom of the connecting frame 18 is rotatably connected to the connecting rod 19 via a bearing, and the bottom end of the connecting rod 19 is fixedly connected to the end pipe 17, allowing the end pipe 17 to rotate relative to the bottom of the connecting frame 18.

[0038] Working principle: The bag containing limestone powder is placed at the feed inlet 8, and the limestone powder is poured into the feeding hopper 6. The limestone powder falls into the cylinder 1, and then the servo motor 2 drives the spiral blades 5 on the surface of the transmission shaft 4 to rotate, pushing the limestone powder until it is discharged through the discharge pipe 9. A dust cover 7 and a dust collection component are installed at the feed inlet of this desulfurization limestone powder conveying device. With the cooperation of the dust collection head 13 and the air duct 12, the fan 11 can suck the dust generated during the limestone powder feeding into the dust collection box 10. The dust is then trapped in the dust collection box 10 by the filter screen 14, thus avoiding harm to human and environmental health. The periodic start-up of the vibration motor 15 can prevent dust from clogging the filter screen 14 and ensure the continuous operation of the dust collection component. The dust collection box 10 has a removable cover on the front, which facilitates the cleaning of limestone powder in the collection box. An adjustment component is provided at the discharge point of the desulfurization limestone powder conveying device. The handle bolt 21 can be loosened so that its end is disengaged from the locking hole 22. At this time, the end tube 17 and the connecting rod 19 can be rotated to adjust the discharge direction. After that, the handle bolt 21 is tightened so that its end is locked into the corresponding locking hole 22 for fixation. Thus, the discharge end orientation of the desulfurization limestone powder conveying device can be adjusted according to the convenience of discharge, with good flexibility.
