Description

Technical Field

[0001] This utility model relates to the field of aluminum plate production technology, and in particular to an aluminum plate cleaning device for aluminum plate production. Background Technology

[0002] In the aluminum sheet rolling process, to ensure the quality of subsequent deep processing steps such as coating and lamination, it is essential to thoroughly clean the surface of the aluminum sheet of contaminants such as residual rolling oil, lubricant, and metal particles. Typical aluminum sheet cleaning equipment in existing technologies usually includes three main processes: chemical cleaning, rinsing, and drying.

[0003] The drying process is the most energy-intensive part of the entire system and a key factor affecting production rhythm. Currently, the industry commonly uses hot air drying technology, which utilizes high-temperature air generated by electric or gas heating, blown onto the surface of the aluminum plate by a fan, evaporating moisture through convection heat transfer. The drawbacks of this method are: hot air has low thermal conductivity, and most of the heat energy is wasted heating the aluminum plate substrate and its surrounding environment, resulting in low energy utilization. To achieve the desired drying effect, very long drying chambers or extremely high air temperatures are often required, leading to bulky equipment, high initial investment, and continuous energy waste, resulting in persistently high production costs.

[0004] Furthermore, if residual liquid droplets on the aluminum plate surface are not adequately removed before entering the drying oven, the aluminum plate will carry a large amount of moisture into the drying stage. The evaporation of this moisture requires a significant amount of latent heat, further exacerbating the energy consumption burden. At the same time, uneven liquid carryover will lead to uneven heating of the aluminum plate in the drying oven, easily causing incomplete drying in certain areas or the formation of water stains, affecting the surface quality of the product.

[0005] Therefore, an aluminum plate cleaning device for aluminum plate production is proposed to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to address the aforementioned shortcomings by providing an aluminum plate cleaning device for aluminum plate production.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: an aluminum plate cleaning device for aluminum plate production, comprising a main body, the main body including a cleaning rack and a placement platform, the placement platform being installed at one end of the cleaning rack, characterized in that a cleaning tank is provided inside the cleaning rack, multiple spray pipes are horizontally arranged on the top side of the cleaning tank, spray nozzles are provided at the bottom end of the spray pipes, a pressurizing component is installed at the top end of the spray pipes, a water pump is installed at one end of the cleaning rack, a water inlet is installed at one end of the water pump and connected to an external water source, a conveying mechanism is installed at the end of the cleaning rack near the placement platform, an infrared preheating module is installed at the top end of the conveying mechanism, and an infrared radiation heater is installed inside the infrared preheating module.

[0008] Furthermore, the infrared radiation heater has a short-wave radiation wavelength, with the main radiation wavelength of the infrared radiation heater ranging from 0.8 μm to 1.4 μm. One end of the conveying mechanism is connected to the placement platform, and the horizontal height of the placement platform corresponds to the horizontal height of the highest end of the conveying mechanism.

[0009] Furthermore, an ultrasonic oscillator is installed on the inner wall of the cleaning tank, and the ultrasonic oscillator operates at a frequency of 40 kHz.

[0010] Furthermore, the conveying mechanism is equipped with a pair of rubber squeezing rollers arranged vertically opposite each other. The rubber squeezing rollers are located on the side of the infrared preheating module near the cleaning tank. The squeezing rollers are used to remove residual cleaning liquid from the surface of the aluminum plate. The infrared preheating module is used to preheat the squeezed aluminum plate to improve the subsequent drying efficiency.

[0011] Furthermore, a hot air drying box is provided behind the infrared preheating module, and the hot air source of the hot air drying box is an electrically heated hot air circulating fan.

[0012] Furthermore, the hot air drying box is installed at one end of the placement platform.

[0013] The beneficial effects of this utility model are reflected in: This invention utilizes an infrared preheating module, along with a squeeze roller and a hot air drying chamber, to form a synergistic drying system. The squeeze roller first mechanically removes most of the residual cleaning liquid, significantly reducing the amount of water that needs to be evaporated. Subsequently, short-wave infrared radiation provides instantaneous and efficient bulk heating to the aluminum plate, causing the remaining thin water film to rapidly heat up and vaporize. This design pre-emptively handles the most energy-intensive "moisture phase change" process, allowing the subsequent hot air drying to focus solely on removing steam and equalizing the temperature. This significantly shortens the overall drying time, substantially reduces heat consumption, and dramatically improves overall energy efficiency. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0017] Please see Figure 1-2 This utility model discloses an aluminum plate cleaning device for aluminum plate production, including a cleaning rack 2 and a placement platform 5. The placement platform 5 is fixedly installed at one end of the cleaning rack 2 and is used to receive clean aluminum plates that have been cleaned and dried.

[0018] A cleaning tank is provided inside the cleaning rack 2. Multiple spray pipes 202 are horizontally mounted on the top of the cleaning tank, extending along the width of the aluminum plate. Each spray pipe 202 has a series of spray nozzles at its bottom, preferably nozzles capable of forming a fan-shaped water curtain to ensure uniform, comprehensive rinsing of the aluminum plate surface. To maintain stable spray pressure, a pressurization component is integrated into the top pipe of the spray pipe 202. A water pump 201 pumps in external water; after being pressurized by the pressurization component, the water is finally sprayed at high speed from the spray nozzles through the spray pipes 202.

[0019] Furthermore, a conveying mechanism is installed at one end of the cleaning rack 2 near the placement table 5. This mechanism is typically a motor-driven roller conveyor system, which is responsible for carrying and conveying the aluminum plates through the various functional areas in sequence.

[0020] In one optional implementation, the infrared preheating module 3 has been optimized for performance. The infrared radiation heater 301 used is a short-wave type, with its main radiation wavelength precisely configured between 0.8 micrometers and 1.4 micrometers. Infrared radiation in this band has a high absorption rate for both water and aluminum, enabling efficient energy conversion and rapid heating of the aluminum plate and its surface moisture. Furthermore, the discharge end of the conveying mechanism is smoothly connected to the placement platform 5, meaning the working surface of the placement platform 5 is level with the highest point of the conveying mechanism rollers, ensuring a smooth transition during the aluminum plate transport process.

[0021] Furthermore, particularly in removing microscopic oil stains and particles, an ultrasonic oscillator 203 is installed on the inner wall of the cleaning tank. This ultrasonic oscillator 203 preferably operates at a frequency of 40 kHz, which generates a strong cavitation effect in the cleaning fluid, effectively stripping away deposits without damaging the aluminum plate surface.

[0022] Furthermore, along the conveying path, in front of the inlet of the infrared preheating module 3, i.e., on the side near the cleaning tank, a pair of opposing rubber squeezing rollers are installed. The function of these squeezing rollers is to physically remove the large amount of residual liquid droplets carried by the aluminum plate after passing through the cleaning tank through mechanical squeezing. This step is crucial, as it significantly reduces the amount of water that needs to be evaporated, directly reducing the energy consumption of the subsequent thermal drying process.

[0023] Furthermore, the squeezed aluminum sheet then enters the infrared preheating module 3. Here, short-wave infrared radiation provides instantaneous and efficient bulk heating to the aluminum sheet, causing its temperature to rise rapidly. The thin water film adhering to its surface is thus quickly heated to near vaporization. This preheating process transfers most of the energy required to heat liquid water to steam from the subsequent convection drying stage to this stage, utilizing a more energy-efficient radiative heating method, thereby improving overall drying efficiency.

[0024] Furthermore, following the infrared preheating module 3, the device also integrates a hot air drying chamber. The hot air in this drying chamber is supplied by an electrically heated hot air circulating fan. Its function is to perform the final processing on the aluminum plates, which have been substantially dried after infrared preheating, ensuring the uniformity of temperature across the entire surface of the aluminum plate and eliminating any potential localized moisture. The hot air drying chamber is installed at the beginning of the placement platform 5, forming a continuous production layout.
