Description

Technical Field

[0001] This utility model relates to the technical field of steel strip degreasing and cleaning equipment, specifically to a copper strip surface degreasing and cleaning equipment. Background Technology

[0002] In the production of copper strip, surface cleanliness is one of the key factors in ensuring the quality of the final product. During the rolling and annealing processes, various contaminants, such as rolling oil and oxides, can easily remain on the surface of the copper strip. These contaminants not only affect the aesthetic appearance of the copper strip, but more importantly, they directly impact the material's performance and the quality of the finished product during subsequent processing. For example, if oil or an oxide layer is present on the copper strip surface before electroplating or coating, it may lead to uneven plating or even failure to adhere the coating. Furthermore, high-precision copper materials used in the manufacture of precision instruments require an even higher standard of surface purity.

[0003] Therefore, degreasing and cleaning has become an indispensable step in the entire production process to remove these impurities that are detrimental to subsequent processes. Traditional degreasing and cleaning methods typically involve immersing the copper strip to be treated in an ultrasonic cleaning tank containing a specially formulated cleaning agent. The bursting of tiny bubbles generated by ultrasonic vibrations helps to peel off and dissolve the dirt particles adhering to the metal surface. While this method effectively removes most contaminants, the cleaning solution gradually becomes contaminated and loses its effectiveness during use, requiring regular replacement to maintain cleaning efficiency. However, frequent replenishment or complete replacement of the cleaning agent undoubtedly increases the company's operating costs. Utility Model Content

[0004] To address the aforementioned problems, this invention provides a copper strip surface degreasing and cleaning device, which aims to achieve the recycling and reuse of the cleaning fluid in the ultrasonic cleaning tank.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a copper strip surface degreasing and cleaning device, comprising an ultrasonic cleaning tank, an overflow port on the left side of the ultrasonic cleaning tank, a filter tank below the overflow port outlet, the filter tank being connected to an oil-water separator tank via a first screw pump, an aeration system being provided on the side wall of the oil-water separator tank, a recovery system being provided at the top of the oil-water separator tank, and an outlet pipe being provided at the bottom of the oil-water separator tank, the outlet pipe being connected to a circulation pipe via a second screw pump.

[0006] Furthermore, the oil-water separator includes a tank body, a level gauge is provided on the outer wall of the tank body, a stirring motor is provided on the top of the tank body, a stirring fan is provided at the output end of the stirring motor, an exhaust pipe is provided on the top of the tank body, an oil-water separation disc is provided inside the tank body, the oil-water separation disc divides the inner part of the tank body into an oil collection chamber and a water collection chamber, an oil outlet is provided on the oil-water separation disc, and a support is provided on the bottom side wall of the tank body.

[0007] Furthermore, the aeration system includes a flotation pump, the output end of which is provided with an upper air outlet pipe and a lower air outlet pipe, and both the upper air outlet pipe and the lower air outlet pipe are provided with air valves.

[0008] Furthermore, the recovery system includes a recovery pipe, one end of which is located in the oil collection chamber, and the other end of which is provided with an oil collection tank. An oil valve is provided on the recovery pipe, and an oil drain valve is provided on the oil collection tank.

[0009] Furthermore, the ultrasonic cleaning tank includes a tank body, with transmission rollers provided at the left and right ends of the tank body, a support roller provided at the upper end of the tank body, and a guide roller provided inside the tank body.

[0010] Furthermore, a filter screen is provided inside the filter tank, and a water outlet pipe is provided on the side wall of the filter tank. The water outlet pipe is connected to a first screw pump, and a water inlet pipe is provided at the output end of the first screw pump. A water valve is provided on the water inlet pipe.

[0011] Furthermore, a circulating water valve is installed on the circulating pipe.

[0012] This utility model has the following beneficial effects:

[0013] The overflow port of the ultrasonic cleaning tank sends the grease and cleaning fluid on the surface of the liquid in the ultrasonic cleaning tank to the filter tank. Impurities are filtered out in the filter tank, and then the first screw pump sends it to the oil-water separator. The oil-water separator separates the grease from the cleaning fluid. The cleaning fluid is returned to the ultrasonic cleaning tank through the circulation pipe for reuse, while the grease is collected and recycled through the recovery system. This achieves the recycling of the cleaning fluid in the ultrasonic cleaning tank, avoiding the increased operating costs caused by frequent replenishment or complete replacement of the cleaning fluid.
