Description

TECHNICAL FIELD

[0001] The present application relates to a surface oil removal device and method for strip metal production, and belongs to the technical field of strip production. BACKGROUND

[0002] The strip is a strip metal material supplied in a roll with a large length-width ratio. The strip with a width greater than 600 mm is called wide strip, and the strip with a width less than 600 mm is called narrow strip. The thickness of the strip can be as thin as 0.001 mm. The cold rolling method can produce thinner specifications of the strip with good surface quality, accurate size and high mechanical properties. Generally, after the strip is produced by the cold rolling machine, the surface of the strip will be left with lubricating oil. In order to save resources and clean the strip, it is necessary to recover and clean the oil on the surface of the strip.

[0003] Application No. CN2010105460554 discloses a cold rolling machine strip surface oil suction device, which comprises a negative pressure generating pipe and an oil discharge pipe. The negative pressure generating pipe is provided with a gas inlet and a gas outlet in communication. The flow area of the gas outlet is greater than that of the gas inlet. One end of the oil discharge pipe is an oil suction port, and the other end is connected to the negative pressure generating pipe and located near the gas outlet of the negative pressure generating pipe. Because the flow area of the gas outlet of the negative pressure generating pipe is greater than that of the gas inlet, when the gas entering from the gas inlet moves to the gas outlet, a negative pressure area is formed in a certain range at the gas outlet due to the increase of the flow area. The fluid in the oil discharge pipe is attracted by the suction force of the negative pressure. In use, the oil suction port of the oil discharge pipe faces the strip. The suction force generated by the negative pressure in the oil discharge pipe can suck away the oil on the surface of the strip and discharge it from the oil discharge pipe, thereby achieving the purpose of automatic oil discharge. The structure of the technical solution can adsorb and recover the oil on the surface of the strip, but cannot achieve complete recovery. Therefore, the surface of the strip needs to be cleaned later, thereby reducing the efficiency.

Use highly absorbent textile materials as oil-absorbing fabrics. Place one set of oil-absorbing fabric onto the upper surface oil-absorbing fabric exit roller, and another set onto the lower surface oil-absorbing fabric exit roller. The oil-absorbing fabric that bypasses the lower oil-absorbing fabric inlet roller enters the belt threading channel through the lower oil-absorbing fabric inlet, perpendicular to the belt and overlapping its upper surface, then wraps around the lower oil-absorbing fabric outlet roller. The oil-absorbing fabric that bypasses the upper oil-absorbing fabric inlet roller enters through the upper oil-absorbing fabric inlet... The absorbent cloth enters the conveyor belt channel, is perpendicular to the conveyor belt and overlaps the lower surface of the conveyor belt, and then is wound around the upper absorbent cloth outlet roller. The absorbent cloth on the lower absorbent cloth outlet roller and the upper absorbent cloth outlet roller are wound around the bottom absorbent cloth inlet roller and reversed to enter the bottom absorbent cloth inlet.
