Detailed Description
The following combines the drawings of the utility model to further elaborate the technical scheme and technical effect of the utility model.
Referring to fig. 1 to 3, in one embodiment, a magnesium slag metal feeding device 10 for cement raw material batching is disposed on a cement raw material batching and conveying device 20, and includes a magnesium slag feeding hopper 100 and a dust reducing assembly 200, wherein the dust reducing assembly 200 includes a wet air feeding pipe 210 and a dust agglomeration separator 220, a discharging end of the magnesium slag feeding hopper 100 is communicated with the wet air feeding pipe 210, a feeding end of the dust agglomeration separator 220 is communicated with a discharging end of the wet air feeding pipe 210, and a discharging end of the dust agglomeration separator 220 is disposed on the cement raw material batching and conveying device 20.
The discharging hole of the magnesium slag feeding hopper 100 is provided with a dust reduction assembly 200, wet air carrying water mist is introduced into the wet air feeding pipe 210, the wet air is in the wet air feeding pipe 210 and the dust agglomeration separator 220, the wet air is fully mixed with magnesium slag entering the wet air feeding pipe 210, the magnesium slag absorbs moisture and is agglomerated, then the wet air is separated from air in the dust agglomeration separator 220, the magnesium slag after humidification and agglomeration enters the cement raw material batching and conveying device 20 from the bottom of the dust agglomeration separator 220, so that the amount of magnesium dust generated by impact of the magnesium slag and the cement raw material batching and conveying device 20 is reduced, the loss amount of the magnesium dust in the environment is reduced, and the magnesium dust is prevented from being attached to equipment and the corrosion of the equipment is accelerated.
For example, the humid air feed pipe 210 is further provided with an atomized water feed pipe 230 to enable the increase and adjustment of the water content in the humid air.
In a specific embodiment, the wet air feeding pipe 210 comprises an air inlet pipe 211, a three-way dosing pipe 212 and a magnesium slag moisture absorption pipe 213 which are connected in sequence, wherein one end of the three-way dosing pipe 212 is communicated with the discharge end of the magnesium slag feeding hopper 100, and the discharge end of the magnesium slag moisture absorption pipe 213 is communicated with the feed end of the dust agglomeration separator 220. Magnesium slag temporarily stored in the magnesium slag feeding hopper 100 enters the batching tee pipe 212 from the discharge end at the lower end of the magnesium slag feeding hopper 100, is mixed with humidified air introduced from the air inlet pipe 211, and is carried forward by the humidified air, and in the conveying process, small-particle magnesium slag absorbs moisture in the magnesium slag moisture absorption pipe 213 and is agglomerated into larger particles, and finally is conveyed into the dust agglomeration separator 220.
