Sealing device of drying cylinder, drying cylinder and aluminum skimming pretreatment system

Abstract

The invention provides a sealing device of a drying cylinder, the drying cylinder and an aluminum skimming pretreatment system. The sealing device comprises a shell and an impeller, wherein a first opening portion and a second opening portion are arranged in the shell; the second opening portion is located below the first opening portion and is used for being in butt joint with a feeding port of the drying cylinder so that materials to be dried can move in a direction from the first opening portion to the second opening portion; the impeller is arranged in the shell, is positioned between thefirst opening portion and the second opening portion and is used for blocking the first opening portion and the second opening portion; and the impeller includes a blade groove, the blade groove is used for bearing the materials to be dried, and the impeller is suitable for changing the direction of the blade groove through rotation so that the materials to be dried can fall into the drying cylinder. According to the sealing device, a rotating wheel is used for covering the feeding port of the drying cylinder so that a possibility of overflowing of smoke in the drying cylinder is reduced, thesealing device can be used for blocking the smoke and feeding the drying cylinder at the same time through rotation of the rotating wheel, and continuous operation of the drying cylinder is guaranteed.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a sealing device for a drying drum, a drying drum including the sealing device, and an aluminum chip pretreatment system including the drying drum. Background technique [0002] At present, aluminum products companies such as aluminum alloy wheels produce a large amount of aluminum chips every day. The recycling and reuse of aluminum chips usually requires steps such as collection, crushing, water removal, drying, iron removal, and remelting of aluminum chips. Aluminum shavings should be collected in fashion frames for recycling to avoid a large amount of aluminum shavings accumulating to occupy space and funds. The existing aluminum chip pretreatment system will generate more flue gas during the drying process, which will overflow from the feeding port of the drying cylinder. The overflow of high-temperature flue gas will cause heat loss, and at the same time du...

AI Technical Summary

Problems solved by technology

The existing aluminum chip pretreatment system will generate more flue gas during the drying process, which will overflow from the feeding port of the drying cylinder. The overflow of high-temperature flue gas will cause heat loss, and at the same time due to the Contains cutting fluid, lubricating oil and other organic volatiles, and the overflow of flue gas is easy to cause environmental pollution. With the continuous improvement of environmental protection requirements, the current aluminum scrap pretreatment system can no longer meet the treatment requirements of energy saving and emission reduction.
