Degreasing device for degreasing tank

Abstract

The invention discloses a degreasing unit of a degreasing tank. The left end of the degreasing tank protrudes leftwards to form an extension section, a longitudinal partition is arranged in the front of the extension portion so as to form an isolation area, a splitter plate with the middle protruding rightwards is arranged on the right side of the longitudinal partition, the upper portion of the splitter plate is higher than the set liquid level, grease inlet passages are reserved between the front and rear ends of the splitter plate and the side wall of the degreasing tank, slots are formed in the positions, corresponding to the grease inlet passages, of the longitudinal partition, and an unpowered deflection-type oil skimmer is arranged in the isolation area. Fluctuation of surge is eliminated at the liquid inlet end with relatively small wave through the isolation area and by the aid of the splitter plate, meanwhile the liquid containing more grease on the upper layer is collected, oil liquid collection effect of the oil skimmer is improved effectively, and overall degreasing effect is improved.

Description

technical field [0001] The invention relates to the technical field of automobile processing, in particular to a degreasing device for a degreasing tank. Background technique [0002] The pre-treatment of automobile painting is an important process line, and degreasing is the primary key process. In order to obtain good coating quality and meet the requirements of coating corrosion resistance and appearance decoration, the degreasing liquid in the degreasing tank is used for a period of time In the end, there will be a lot of oil slick or oil particles, and the oil content is only about thousands of ppm, but its impact on production quality cannot be ignored, which requires oil-water separation of the degreasing liquid. Traditional oil-water separation generally uses pumps Suction the surface liquid layer or set up a branch in the circulation pipeline to obtain the liquid and separate it from oil and water. However, due to the large fluctuation of the liquid level in the deg...

[0002] The pre-treatment of automobile painting is an important process line, and degreasing is the primary key process. In order to obtain good coating quality and meet the requirements of coating corrosion resistance and appearance decoration, the degreasing liquid in the degreasing tank is used for a period of time Finally, there will be a lot of oil slicks or oil particles, and the oil content is only about several thousand ppm, but its impact on production quality cannot be ignored. This requires oil-water separation of the degreasing liquid. Traditional oil-water separation generally uses pumps Suction the surface liquid layer or set up a branch in the circulation pipeline to obtain the liquid and separate it from oil and water. However, because the liquid level in the degreasing tank fluctuates greatly, the liquid sucked by the pump or the grease content in the circulation pipeline is very low, resulting in actual The effective oil removal rate is low, resulting in energy waste
