Accompanying drawing explanation
Fig. 1 is the structural representation that water fog method of the present utility model prepares copper powder atomization bucket.
In figure: 1-staving; 2-discharge bucket; 3-feeding mouth; 4-butterfly valve; 5-baffle plate.
Detailed description of the invention
The technical solution of the utility model is further illustrated by detailed description of the invention below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of water fog method prepares copper powder atomization bucket, comprise columniform staving 1, the bottom of staving 1 is connected with the discharge bucket 2 of back taper, the top of staving 1 is connected with the feeding mouth 3 of taper, the bottom of discharge bucket 2 is connected with butterfly valve 4, and the madial wall of staving 1 is removably connected with the baffle plate 5 of multiple intervals annular arrangement at least one cross section.It is in preparation process, and copper powder enters staving from feeding mouth, and through the collision of baffle plate, generation is touched flat, thus reduces the sphericity of copper powder, and then prepares the copper powder of low loose ratio.
Preferably, the cone angle of feeding mouth 3 is greater than the cone angle of discharge bucket 2.Particularly, in the present embodiment, the cone angle of feeding mouth 3 is 150 °, and the cone angle of discharge bucket 2 is 110 °.Therefore, the entrance opening dimension of feeding mouth is less relative to the discharging size of discharge bucket, thus ensures that the copper powder entered in staving can obtain touching flat, and then avoids entering the pressure that staving or the material in staving too much cause baffle plate simultaneously.And utilize the butterfly valve 4 of the outlet of discharge bucket effectively to control discharging, ensure the time of material in staving, thus ensure collision mass.
