Ultrasonic treatment-air floatation integrated oil removal equipment

Abstract

The invention relates to the technical field of pretreatment in the electroplating industry, in particular to ultrasonic treatment-air floatation integrated oil removal equipment. The equipment comprises an ultrasonic oil removal area and an air floatation area, wherein the air floatation area comprises a circulating water pump, an air dissolving pump, an air dissolving tank and an air floatationtank; the air floatation tank is sequentially provided with a wastewater area, an air floatation control chamber, an air floatation separation chamber, a slag discharge tank and a clear water area; the air flotation control chamber is provided with a dissolved air releaser; a slag scraping device is arranged above the air flotation separation chamber; the clear water area is connected with the circulating water pump through a pipeline; the circulating water pump is connected with an oil-removing tank I and an oil-removing tank II through pipelines; the oil-removing tank I and the oil-removingtank II are connected with the wastewater area through pipelines; the wastewater area is connected with the air floatation control chamber through a partition plate; and a spiral gate is arranged at the upper end of the clear water area. According to the invention, the ultrasonic oil removal principle and the air floatation principle are combined to remove oil and rust of parts, so a water circulation utilization rate and oil-water separation effect are improved; and therefore, wasting is reduced.

Description

technical field [0001] The invention relates to the technical field of pretreatment in the electroplating industry, in particular to an ultrasonic and air flotation integrated degreasing equipment. Background technique [0002] In the electroplating industry, ultrasonic degreasing and rust removal are often required for pre-plating treatment. The "cavitation" effect generated by ultrasonic waves can enhance the degreasing effect; the industrial sewage generated is often directly discharged to sewage treatment plants, and the water recycling rate is extremely low. , resulting in a great waste. Contents of the invention [0003] The purpose of the patent of the present invention is to provide an ultrasonic and air flotation integrated degreasing equipment for the deficiencies of the existing technology, which combines the principle of ultrasonic degreasing and air flotation to degrease and derust parts, improve the water cycle utilization rate and oil-water separation effec...
