Aluminum and aluminum alloy slab sawdust compacting device

Abstract

The invention discloses an aluminum and aluminum alloy slab sawdust compacting device comprising a separation cover. The right side of the upper end of the separation cover is provided with a PLC, andthe side of the separation cover is provided with support legs; and the front and rear sides of the upper end of the separation cover are provided with a feeding pipe and an exhaust pipe oppositely,and a shaft hole in the upper end face of the separation cover is internally provided with a rotating shaft. The aluminum and aluminum alloy slab sawdust compacting device is simple in structure and easy to use, and aluminum scraps are sucked through the feeding pipe; air flow and the aluminum scraps are separated when the aluminum scraps pass through rotating blades; the aluminum scraps are squeezed by a pushing plate in a compression barrel, and hot melted and bonded through cooperative heating of an electric heater, so that the effective surface area of the aluminum scraps is decreased, andthe aluminum scraps are prevented from being burnt in a high-temperature furnace chamber; the utilization rate of the aluminum scraps is improved, and the overall smelting and processing are ensured;blocky compaction blocks are formed through pressing by a pressing plate, and are easy to smelt in a smelting furnace; the transport is convenient, and dust pollution is not generated; and the compacting device is easy to operate and manage.

Description

technical field [0001] The invention relates to the technical field of aluminum scrap recycling and processing, in particular to a sawdust compacting device for aluminum and aluminum alloy flat ingots. Background technique [0002] In the production process of aluminum and aluminum alloy flat ingots, the two ends of the flat ingots need to be sawed with a sawing machine, and a large amount of sawdust is generated during sawing. When these sawdusts are added to the melting furnace for remelting, they are powdery and float On the surface of the molten aluminum, a large area directly contacts the high-temperature furnace gas and high-temperature primary aluminum in the smelting furnace chamber, and is quickly oxidized, and the burning loss rate reaches 95% during remelting, causing great waste, and the operation is labor-intensive. There are certain potential safety hazards, and at the same time, it affects environmental sanitation and is not conducive to on-site management. Th...

[0002] In the production process of aluminum and aluminum alloy flat ingots, the two ends of the flat ingots need to be sawed with a sawing machine, and a large amount of sawdust is generated during sawing. When these sawdusts are added to the melting furnace for remelting, they are powdery and float On the surface of the molten aluminum, a large area directly contacts the high-temperature furnace gas and high-temperature primary aluminum in the smelting furnace chamber, and is quickly oxidized, and the burning loss rate reaches 95% during remelting, causing great waste, and the operation is labor-intensive. There are certain potential safety hazards, and at the same time, it affects environmental sanitation and is not conducive to on-site management. The existing sawdust processing equipment has a complex structure, is easy to collect materials, and does not meet the processing requirements of sawdust.
