Large aluminum fin automatic cleaning device and method

Abstract

The invention relates to a large aluminum fin automatic cleaning device and method. The device comprises a set of main equipment production line, a set of deionized pure water preparation system, and a set of equipment lifting transmission system. A feeding platform and a discharge platform are respectively disposed in the front and at the rear of the main equipment production line. The feeding platform is a conveying platform on the feeding side of the main equipment production line. The discharge platform is a conveying platform on the discharge side of the main equipment production line. The feeding platform and the discharge platform are parallel with the main equipment production line. The feeding platform is provided with rollers. At least one movable cleaning basket which can move on the main equipment production line is disposed on the feeding platform. The main equipment production line is combined by a plurality of cleaning tanks which are connected in sequence. The equipment lifting transmission system uses a carbon steel roller chain as a transmission carrier for up-down movements and uses a gear motor and a linear slide rail as a transmission carrier for longitudinal and transverse movements and fixed-station cleaning. The deionized pure water preparation system which can continuously produce high-purity deionized water is connected with at least one deionized water tank which is communicated with at least one cleaning tank of the main equipment production line.

Description

technical field [0001] The invention relates to an automatic cleaning device and method for heat transfer fins of an aluminum plate-fin heat exchanger, belonging to the technical field of cleaning automation. Background technique [0002] Heat transfer fins are the core parts of the aluminum plate-fin heat exchanger, and their cleaning quality directly affects the brazing quality of the plate-fin heat exchanger, and ultimately affects the performance of the heat exchanger. For a long time, the traditional acid and alkali leaching method is usually used for punched aluminum alloy fins, and the original manual cleaning method has the following main disadvantages: [0003] 1) Unstable quality: the original process adopts the traditional method of acid-base cleaning and washing with water, the oil content and surface cleaning fluid residue cannot be controlled; the cleaning time depends on the experience of the operator, and the cleaning quality stability is difficult to g...

AI Technical Summary

Problems solved by technology

[0003] 1) Unstable quality: the original process adopts the traditional method of acid-base cleaning and washing with water, and the oil content and surface cleaning liquid residue cannot be controlled; the cleaning time depends on the experience of the operator, and the cleaning quality stability is difficult to guarantee; in addition, tap water Contains salt and Ca, Mg ions, rinse with tap water, water stains will appear after washing and drying

[0004] 2) High production cost: the original cleaning process needs to use large flow of water for flushing, and its essence is to use tap water only as a diluent, which has the disadvantages of high energy consumption, high consumption of cleaning agent, large waste water discharge and Disadvantages such as difficult treatment and high price of wastewater treatment increase production costs

[0005] 3) Low production efficiency: the conversion between various cleaning processes is carried out by means of driving and lifting, which has a low degree of automation, high labor intensity, and low production efficiency. When the output demand increases, the production of the original equipment cannot meet the demand

[0006] 4) Does not meet environmental protection requirements: The cleaning solution used in the traditional acid-base cleaning process is strong acid and strong alkali, which increases the danger of the operation process when configuring strong acid and strong alkali, and the smoke generated by strong acid and strong alkali is easy to pollute the air and the environment , affecting human health, and the discharge of cleaning wastewater is large, which does not meet the requirements of environmental protection
