Problems solved by technology

This scheme has two deficiencies. First, the process of oil floating from the degreasing liquid to the liquid surface of the degreasing tank occurs in a natural state. Suspended in the degreasing liquid, the collection efficiency is low; secondly, the heating method of the degreasing tank liquid generally adopts electric heating, steam or high-temperature water, which needs to increase energy consumption, does not make full use of the waste heat produced in the painting workshop, and is not energy-saving, so we Provide a new degreasing method applied to body pretreatment

Abstract

The invention discloses a novel oil removal method applied to pretreatment of an automobile body, and relates to the technical field of automobile production and manufacturing, the oil removal method comprises the steps of gas preparation, gas dissolving, floating, collection, heating and separation. According to the method, a gas-liquid mixed state is made in degreasing fluid, in the rising process of gas microbubbles, grease suspended in the degreasing liquid is brought to the liquid level of the degreasing tank and gathered through jacking, adsorption and clamping, and the collection efficiency is much higher than that of a grease natural floating mode; production waste heat of a coating workshop is fully utilized in heating of the degreasing tank, energy is greatly saved, and the method is efficient, energy is saved, and components of degreasing fluid are not damaged.

Description

technical field [0001] The invention relates to the technical field of automobile production and manufacturing, and the specific field is a novel degreasing method applied to the pretreatment of vehicle bodies. Background technique [0002] In the automotive and other industrial coating processes, pretreatment is an important process, and its main process is degreasing, in which the grease and dirt attached to the workpiece are removed. Part of the oil undergoes a saponification reaction under the action of the degreasing liquid and dissolves in water, and part of the oil is emulsified and suspended in the degreasing liquid as fine droplets. If the oil in the degreasing liquid is not removed in time, it will not only affect the cleaning effect of the car body, It will also cause secondary pollution to the body, which will affect the quality of the electrophoretic paint film on the body. At present, the commonly used degreasing scheme in the industry collects the oil mixture...
