Description

Technical Field

[0001] The utility model relates to the technical field of powder filtration, in particular to a circulating multi-stage filtration device for iron removal of powder materials. Background Technique

[0002] Powder filtration refers to screening out the materials of other components mixed in the powdery materials so as to carry out subsequent processing on the powder. The iron filings in the powder are usually removed by repeatedly stirring and adsorbing the materials in the bin with a magnetic iron removal mechanism so as to adsorb and filter the iron filings in the powder.

[0003] A powder circulating iron removal device disclosed in the publication number CN206286054U realizes the repeated iron removal of materials by arranging a plurality of conical magnets and iron removal caps at intervals in the box body. The contact area between the conical iron removal cap and the materials is large, and the iron removal effect is good. Moreover, this multi-layer repeated iron removal method further improves the iron removal effect of the materials. At the same time, the device ensures the iron removal quality of the materials through the circulating iron removal of the materials. In addition, the device is convenient for later iron cleaning and maintenance, and has strong practicability.

[0004] However, the above-mentioned circulating iron removal device for powder still has the following problems in the actual use process: Although a plurality of conical iron removers are used to realize the adsorption and filtration of iron filings, as an easily agglomerated and caked material, the powder is easy to wrap and stick the iron filings during the agglomeration process. Therefore, in the process of directly removing iron by any crushing means inside, it is easy to cause omissions and residues. At the same time, the conical iron remover cannot clean itself, and it is easy to reduce the suction force after adsorbing more iron filings on the surface, resulting in the situation that the iron filings cannot be filtered, which affects the iron removal effect of the powder.

[0005] Therefore, we propose a circulating multi-stage filtration device for iron removal of powder materials to solve the problems mentioned above. Content of the Utility Model

[0006] The purpose of the utility model is to provide a circulating multi-stage filtration device for iron removal of powder materials, aiming at solving the problems that although the existing iron removal and filtration device uses a plurality of conical iron removers to realize the adsorption and filtration of iron filings, as an easily agglomerated and caked material, the powder is easy to wrap and stick the iron filings during the agglomeration process. Therefore, in the process of directly removing iron by any crushing means inside, it is easy to cause omissions and residues. At the same time, the conical iron remover cannot clean itself, and it is easy to reduce the suction force after adsorbing more iron filings on the surface, resulting in the situation that the iron filings cannot be filtered, which affects the iron removal effect of the powder.
