Description

Technical Field

[0001] The present invention belongs to the technical field of glue spraying devices, and particularly relates to a glue spraying device and method suitable for attaching an evaporator to an inner tank. Background Art

[0002] The evaporator and the inner tank are core components in modern household appliances and industrial equipment. The two work together to achieve heat exchange and medium treatment functions. The evaporator is the core carrier of heat exchange. The evaporator realizes energy conversion through the physical process of liquid medium vaporization and heat absorption. Its design needs to take into account heat transfer efficiency and medium compatibility. The heat exchange tube bundle inside it is composed of metal tubes, with liquid medium flowing inside and contacting the gas or liquid to be treated outside. When the medium vaporizes in the tube, it absorbs the heat outside the tube to achieve the effect of cooling or humidifying. The fins are used to enhance heat transfer. The metal fins wrap the tube bundle to improve the heat exchange efficiency by increasing the surface area. The liquid distribution and steam collection device ensures that the liquid medium is evenly distributed to each heat exchange tube and collects the vaporized gas to maintain the system pressure stability. As the outer shell of the evaporator, the inner tank needs to withstand the pressure generated by the vaporization of the medium and prevent leakage at the same time. Its material needs to have high strength and corrosion resistance. The inner design of the inner tank has flow channels or cavities to guide the medium to be treated to fully contact the heat exchange tube bundle and improve the heat exchange efficiency. The spraying process forms a functional coating on the surface of the metal substrate to solve the durability and efficiency problems of the evaporator under complex working conditions, and is mostly used in high-humidity, acidic or alkaline medium environments. When spraying, the material needs to match the thermal expansion coefficient of the substrate (such as stainless steel, aluminum alloy) to avoid coating peeling at high temperatures, and the surface of the inner tank needs to be pretreated by sandblasting, pickling, etc. before spraying to improve the coating adhesion. For example, by using materials such as epoxy resin and polytetrafluoroethylene, a dense isolation layer is formed to block the contact between the medium and the metal substrate. For example, after spraying a PTFE coating on the inner tank of a seawater desalination evaporator, the chloride ion corrosion resistance is increased by more than 10 times. In scenarios that require frequent cleaning, the nano-scale hydrophobic and oleophobic coating can make oil stains and water scales difficult to adhere, and the cleaning efficiency is increased by more than 50%. In fields with strict hygiene requirements such as medical treatment and food processing, the coating loaded with antibacterial agents such as silver ions and zinc oxide can damage the bacterial cell membrane and inhibit its reproduction. Therefore, it is very necessary to provide a glue spraying device and method suitable for attaching an evaporator to an inner tank. Summary of the Invention
