And pollution is reduced

The utility model relates to a clean production and deep processing technology of aluminum and copper. The utility model relates to a device, in particular to a pollution-reducing alloy composite beltoxide layer removing device. The device comprises a shifting dust suction device A, a shifting dust suction device B, a funnel, a conical column, a horizontal supporting rod and a hose, the shiftingdust suction device A comprises a dust suction column A, a connecting rod and an air suction pipe A, and the shifting dust suction device B comprises a transverse supporting rod, a vertical supportingrod, a dust suction column B and an air suction pipe B. The device has the advantages that when the brush roller A and the brush roller B are used for brushing the alloy composite belt to remove an oxide layer, the brush roller A and the brush roller B are not prone to being contaminated by much dust after long-time use, secondary pollution to the alloy composite belt is avoided, and the using effect of reducing pollution
