Raw material iron powder charging device

Abstract

The invention discloses a raw material iron powder charging device, which comprises a hopper, a fixing ring, a rib sheet, an outer round tube, an outer paper board round tube, an inner paper board round tube, an inner round tube, an annular paper board bottom and a charging round tube. The original raw material iron powder charging device needs to lift out the outer round tube and the inner round tube, the fixing rib sheet needs to pass through raw material iron powder contained in a cavity arranged between the outer round tube and the inner round tube, deep grooves can be formed on the surface of the raw material iron powder, the manual cleaning by a great amount of labor is needed, the cleaning cost is increased, and the product quality is also seriously influenced. The raw material iron powder charging device has the advantages that because of the adoption of a paper board round sleeve unit formed by the inner paper board round tube, the outer paper board round tube and the annular paper board bottom, the surface of the obtained primary reducing iron is smooth, the cleaning is very easy, no impurity is remained, the purity and the quality of the reducing iron are improved, the high quality of the iron powder for powder metallurgy preparation is ensured, and the problem which is not solved for a long time in the technical field is solved.

Description

technical field [0001] The invention relates to a raw material iron powder charging device. Background technique [0002] After drying the raw iron powder for primary reduction iron or powder metallurgy, it should be loaded into the silicon nitride cylinder with the raw material iron powder charging device, and then the silicon nitride cylinder should be loaded into the tunnel kiln. On the feeding trolley, it is sent to the tunnel kiln for reduction. [0003] Such as Figure 1-2 As shown, the existing raw material iron powder charging device includes, funnel 21, fixed ring 22, first fixed rib 23, second fixed rib 24, the third fixed rib 25, charging cylinder 26, round outer Tube 27, circular inner tube 28, limit piece 29; [0004] The hanging beam 20 is fixed on the top of the funnel 21; the fixed ring 22 is a ring, the fixed ring 22 is welded on the lower end of the funnel 21, and the fixed ring 22 is placed in the charging cylinder 26 close to the inner wall of the charg...

AI Technical Summary

Problems solved by technology

[0008] Problem is: owing to will circle outer tube 27, circle inner tube 28 hang out, the 3rd fixed rib 25 will pass through the raw material iron powder that packs in the cavity between circle outer tube 27, circle inner tube 28, will make The surface of the raw iron powder slides out of the deep groove, and the coal powder in contact will be scattered into the deep groove on the surface of the raw iron powder, so that the coal in the deep groove on the surface of the obtained direct reduction iron powder needs to be manually cleaned with a lot of manpower, increasing Clean up costs, but also seriously affect product quality
