[0016] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0017] like Figure 1-Figure 3As shown, a dust-proof magnesium oxide powder unloading device comprises: a machine platform 1, a screw conveyor 2 is installed on the machine platform 1, and a hopper 3 is installed on the screw conveyor 2; the screw conveyor 2 is explained as follows: a fixed block is fixedly installed on the top of the machine platform, a feeding cylinder is fixedly installed on the upper end of the fixed block, a rotating shaft is arranged inside the feeding cylinder, a plurality of groups of stirring blades are arranged on the surface of the rotating shaft, a coupling is sleeved on the output end of the motor, and the motor is connected to one end of the rotating shaft through the coupling, the hopper 3 is installed on the upper end of the conveying cylinder, and a unloading dust removal component; the unloading dust removal component comprises a discharge pipe 12 installed at the bottom of the screw conveyor 2, and the discharge pipe 12 is connected to the discharge end of the screw conveyor 2; a telescopic hose 6 is installed at the bottom of the discharge pipe 12, and a movable guide pipe 7 is installed at the bottom of the telescopic hose 6, a mounting block 4 is installed on the screw conveyor 2, an electric push rod 9 is installed on the mounting block 4, a movable plate 5 is fixed on the output end of the electric push rod 9, and the guide pipe 7 passes through the movable plate 5 and is fixedly connected to it.

[0018] When the magnesium oxide powder is put into a box or a bag, the electric push rod 9 drives the moving plate 5 to move, so that the guide tube 7 can be moved. At this time, the telescopic hose 6 is extended and retracted, so that the guide tube 7 is close to the inner bottom of the box or the bag. Since a valve 13 is installed on the guide tube 7, the valve 13 can be a solenoid valve. When the valve 13 is opened and the screw conveyor 2 works, the magnesium oxide powder can be discharged through the discharge pipe 12, the telescopic hose 6 and the guide tube 7. Since the guide tube 7 moves downward, the height to which the magnesium oxide powder falls is reduced, thereby reducing dust.

[0019] A collecting box 8 is installed on the machine 1, and a negative pressure fan 10 is installed on the collecting box 8. An air inlet pipe is installed at the air inlet end of the negative pressure fan 10, and the air inlet pipe passes through the collecting box 8 and is fixedly connected thereto. A dust suction pipe 11 opposite to the telescopic hose 6 is installed on the collecting box 8, and a filter is installed on the inner wall of the collecting box 8. The negative pressure fan 10 and the dust suction pipe 11 are located on both sides of the filter. A box cover is provided at the upper end of the collecting box 8, and an installation frame is installed in the collecting box 8. The installation frame is fixed by screws, and the filter is fixed in the installation frame. The installation frame can be removed by removing the box cover so as to collect and process the filtered magnesium oxide powder.

[0020] Although the height of the material guide pipe 7 is lowered, dust will still appear when the powder is discharged. At this time, the negative pressure fan 10 is turned on. The operation of the negative pressure fan 10 can allow the external air to enter the collection box 8 through the dust suction pipe 11, so that the dust can be sucked into the collection box 8 and filtered through the filter, and the magnesium oxide powder can be collected, which effectively prevents the occurrence of dust; since the dust suction pipe 11 is a metal shaped hose, the angle and position of the dust suction pipe 11 can be adjusted to facilitate material discharge and dust suction and dust reduction.
