An air outlet pipe 5 is connected to the bottom of one side of the dust collecting box body 1, and a filter cylinder 24 is connected to the top of the dust collecting barrel 2. The filter cylinder 24 is a common dust filtering structure, which is generally provided with clamping mesh plates on both sides and a dust filter cloth cover is provided inside to filter mineral powder.

[0018] During specific implementation: the dust extraction pipeline inside the mineral powder production plant is connected through the dust gas input pipe 3, the dust-containing gas is input into the dust collecting barrel 2, and then the dust is filtered through the filter cylinder 24. The dust can be accumulated inside the dust collecting barrel 2, and then the exhaust valve pipe 4 and the drive motor 16 are opened regularly to quickly and stably discharge the collected dust.

[0019] Combined with Figure 3 The dust box body 1 is connected to an air dividing ring 9 located on the outside of the filter cylinder 24, and the inner side of the air dividing ring 9 facing the filter cylinder 24 is provided with a plurality of air outlet holes 10.
