Automatic cleaning method and device for aluminium alloy composite boards

Abstract

The invention relates to an automatic cleaning method and a device for aluminium alloy composite boards. The method comprises the following steps: putting composite boards on a feeding platform; and orderly transporting the composite boards to an ultrasonic cleaning region, a spraying and rinsing region and an airing and drying region by using a transport mechanism, wherein after the composite boards are transported to the ultrasonic washing region, an ultrasonic cleaning mechanism carries out ultrasonic washing on two sides of each composite board to remove pollutants and part of oxides on the board surface, and a spraying and rinsing mechanism is arranged at the back end of the ultrasonic washing region and used for removing the cleaning solution and impurities, thereby preventing the cleaning solution from being taken into the drying region. The device comprises the ultrasonic cleaning mechanism, the spraying and rinsing mechanism, an air knife dewatering mechanism and a hot air drying mechanism, wherein the transport mechanism is arranged among the ultrasonic cleaning mechanism, the spraying and rinsing mechanism, the air knife dewatering mechanism and the hot air drying mechanism to connect the mechanisms; and the transport mechanism is provided with the feeding platform on which composite boards are put. Compared with the traditional cleaning method, the invention saves the fixed investment by about **yuan, enhances the efficiency by more than 80%, and has high economic benefit.

Description

technical field [0001] This patent relates to an automatic cleaning method and device for an aluminum alloy composite plate of a plate-fin heat exchanger, which belongs to the technical field of cleaning automation. Background technique [0002] The composite plate is the basic heat exchange unit in the aluminum plate-fin heat exchanger, with a thickness of 0.8-1.6mm, a width of 400-1500mm, and a length of less than 8000mm. The cleaning quality directly affects the brazing quality of the heat exchanger, which in turn affects the heat exchanger The safety performance of the heater. In the past, the cleaning of the composite plates of plate-fin heat exchangers used the traditional acid-base immersion method, and the operation required the cooperation of 6 people. For large composite plates, more workers were required to cooperate. Before cleaning, four operators are required to lift the composite board and carefully put the composite board on a special cleaning shelf. The ope...

Problems solved by technology

With the traditional cleaning process, the labor intensity of the workers is high, and the cleaning quality depends on the experience of the operator, so it is difficult to guarantee the stability of the cleaning quality

Sewage from acid-alkali leaching requires acid-base neutralization and precipitation. Sewage treatment equipment occupies a large area, and once the sewage leaks to the ground, it will cause permanent pollution, which does not meet environmental protection requirements.
