Oil removing and degreasing device and method for heat treatment production line

Abstract

The invention belongs to the technical field of heat treatment and particularly relates to an oil removing and degreasing device and method for a heat treatment production line. The device comprises adegreasing tank and a plurality of supporting legs fixed to the bottom of the degreasing tank, wherein a first partition plate and a second partition plate are fixedly arranged in the degreasing tank, and the interior of the degreasing tank is divided into a flushing tank, a scrubbing tank and an ultrasonic cleaning tank by the first partition plate and the second partition plate. The flushing tank, the scrubbing tank and the ultrasonic cleaning tank are arranged in the degreasing tank, a workpiece is washed in the washing tank, relatively obvious grease attached to a surface is removed, through a plurality of layers of roller brushes, the workpiece surface is carefully cleaned and brushed, the workpiece surface can make full contact with a complex surface, then the workpiece is conveyedinto the ultrasonic cleaning tank after being brushed and is cleaned through ultrasonic waves in cooperation with grease removing liquid, the grease on the workpiece surface can be removed more thoroughly, the cleaning liquid is used in a classified mode, the cleaning degree of the cleaning liquid is guaranteed, and waste of the cleaning liquid is reduced.

Description

technical field [0001] The invention belongs to the technical field of heat treatment, and in particular relates to an oil removal and degreasing device and method for a heat treatment production line. Background technique [0002] The degreasing before heat treatment should be to remove the organic matter on the surface, so as to avoid the decomposition of these organic matter at high temperature and produce harmful gases. It is especially important that if the organic matter decomposes to generate hydrogen, the hydrogen will enter the metal at high temperature, causing hydrogen embrittlement, making the metal The strength is greatly reduced. [0003] At present, when heat-treated metal parts are degreased, the workpiece is soaked in the degreasing pool for a period of time, and then the workpiece is fished out. This method is suitable for workpieces with smooth surfaces, but for complex curved workpieces with grooves and threads. In some cases, it is difficult to remove s...

[0002] The degreasing before heat treatment should be to remove the organic matter on the surface, so as to avoid the decomposition of these organic matter at high temperature and produce harmful gases. It is especially important that if the organic matter decomposes to generate hydrogen, the hydrogen will enter the metal at high temperature, causing hydrogen embrittlement, making the metal greatly reduced strength

[0003] At present, when heat-treated metal parts are degreased, the workpiece is soaked in the degreasing pool for a period of time, and then the workpiece is fished out. This method is suitable for workpieces with smooth surfaces, but it is suitable for workpieces with complex curved surfaces, grooves and threads. situation, it is difficult to remove surface grease, so a degreasing and degreasing device that can remove complex surfaces is needed
