Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0056] In the description of the present invention, it should also be noted that, unless otherwise clearly specified and defined, the terms "arrange", "set", "connect", and "join" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0057] As Figures 1-6 shown, the present invention provides a rinsing and antioxidant recycling system for metal sheets. The rinsing and antioxidant recycling system for metal sheets includes a roller conveyor 1, conveying rollers 2, a sealing cover 3, a gas cylinder 4, a gas supply valve 5, a gas supply fan 6, and an exhaust pipe 7.

[0058] The roller conveyor 1 is installed on the ground. The function of the roller conveyor 1 is to transport metal sheets from one working area to another. Through the arrangement of two rows of parallel conveying rollers 2, the stable transmission of metal sheets can be ensured, so that the metal sheets are in an ideal positioning state during rinsing and processing, avoiding uneven processing caused by excessive shaking or position change.

[0059] To prevent the oxidation of metal sheets, there are two rows of conveying rollers 2. The two rows of conveying rollers 2 are arranged in a parallel position relationship and installed on the roller conveyor 1. There is a gap between the two rows of conveying rollers 2. The sealing cover 3 is fixedly installed on the top surface of the roller conveyor 1. The gas cylinder 4 is located on one side of the conveying rollers 2, and the gas cylinder 4 contains inert gas. The gas cylinder 4 provides inert gas to prevent the oxidation of metal sheets. Through the gas supply system, the inert gas is accurately delivered to the surface of the metal sheets to form a protective atmosphere to prevent the occurrence of oxidation reactions. The design of the gas cylinder 4 can be reused in multiple cycles, improving the economy and environmental protection of the system. The gas supply valve 5 is installed at the mouth of the gas cylinder 4. The gas supply fan 6 is installed on one side of the sealing cover 3. The air outlet of the gas supply fan 6 is communicated with the sealing cover 3. One end of the exhaust pipe 7 is communicated with the gas supply fan 6, and the other end of the exhaust pipe 7 is communicated with the air inlet of the gas supply fan 6. This system is applicable to scenarios where metal materials need to be protected from oxidation during processing, storage, or transportation, such as the surface treatment of high-end metal products, medical devices, or aerospace components.

[0060] To fully ensure the purity of the inert gas, a pressure sensor 8 is installed on the inner wall of the sealing cover 3, and an exhaust valve 9 is installed on the outer wall of the sealing cover 3. The exhaust valve 9 is connected to the sealing cover 3 and controls the outflow of the inert gas to ensure that the gas in the system does not leak and guarantee the efficiency of gas circulation. The gas collecting bottle 10 is used to collect the discharged gas and facilitate recycling and treatment. This design helps reduce energy consumption and improve the sustainability of the system. The gas collecting bottle 10 is located on one side of the roller conveyor 1, and the gas collecting bottle 10 is connected to the exhaust valve 9. A condenser 11 is installed at the bottom of the gas collecting bottle 10, and the condenser 11 is connected to the gas collecting bottle 10. An infusion tube 12 is connected to the condenser 11. The condenser 11 is used to condense the moisture in the inert gas, and the moisture will enter the next treatment process together with the inert gas.

[0061] The gas-liquid separator 13 then ensures the complete separation of the moisture from the inert gas and discharges the moisture to improve the circulation efficiency of the system. The infusion tube 12 is provided with several branch pipes, and each branch pipe of the infusion tube 12 is correspondingly connected to the sewage layer of the water tank 15. The gas-liquid separator 13 is connected to the gas bottle 4. The liquid inlet end of the gas-liquid separator 13 is connected to the infusion tube 12, and a drain pipe is provided at the bottom of the gas-liquid separator 13. The present invention is designed for a system for circulating cleaning and oxidation prevention, especially for a system for processing metal sheets in a humid environment. The stability and cleanliness of the equipment are improved through gas-liquid separation.

[0062] A plurality of blanking hoppers 14 are provided. The plurality of blanking hoppers 14 are arranged side by side below the conveying rollers 2. The cross-sectional shape of the blanking hopper 14 gradually narrows from top to bottom. The water tank 15 is located below the blanking hopper 14. The water tank 15 is a stratified water tank 15. The number of water supply valves 16 provided corresponds to that of the water tank 15 one by one. The water supply valves 16 are installed on the water tank 15. The water inlets of the water supply valves 16 are connected to the purified water layer of the water tank 15. The number of spray pipes 17 provided corresponds to that of the water supply valves one by one. The spray pipes 17 are installed in the sealing cover 3. The spray pipes 17 are located above the conveying rollers 2. Each spray pipe 17 is connected to the corresponding water supply valve 16.

[0063] The spray pipes 17 are used to evenly spray the purified water in the water tank 15 on the surface of the metal sheet to achieve the effect of removing oil stains, dust and other impurities. The stratified design of the water tank 15 separates the purified water layer from the sewage layer, facilitating management and recycling. The spray system has a wide range of applications in the fields of metal surface cleaning, electronic equipment assembly and cleaning. Spray cleaning is often used in the factory automation production line, and the processing process is efficient and continuous.

[0064] The drying machine 18 is installed on the other side of the roller conveyor 1. The oven 19 is installed on top of the drying machine 18. Both ends of the connecting pipe 20 are connected to the drying machine 18 and the oven 19. There is a cavity between the oven 19 and the drying machine 18. The conveying rollers 21 are arranged in the cavity provided between the oven 19 and the drying machine 18. The horizontal height of the conveying rollers 21 is lower than that of the conveying rollers 2. The drying machine 18 and the oven 19 are used in combination, which can effectively remove the excess moisture or liquid on the surface of the metal sheet. The cavity design can provide uniform heat for the metal sheet, enabling the metal sheet to dry quickly after treatment and avoiding the secondary influence of moisture on the metal surface. When drying the metal sheet, especially when there is moisture or chemical liquid residue on the surface of the metal sheet, the drying machine 18 and the oven 19 can effectively remove these excess substances.

[0065] The conveying rollers 2 further include: positioning rollers 201 distributed in the roller conveyor 1, brush rollers 202 located on one side of the positioning rollers 201, with a brush roller 202 distributed every other positioning roller 201, and absorbent cotton rollers 203 located directly below the spray pipe 17. The absorbent cotton is arranged in a continuous distribution, and the number of continuous distributions of the absorbent cotton is determined by the spraying range of the spray pipe 17. The brush rollers 202 are used to remove impurities on the surface of the metal sheet, such as oil stains or dirt, to ensure that the metal sheet is clean and tidy before entering the spraying system. The absorbent cotton rollers 203 can further absorb water after the metal sheet leaves the cleaning area, ensuring that the surface of the metal sheet is dry and free of water residue.

[0066] Through the combination of multiple functional modules, the present invention can achieve efficient and automated processing of metal sheets in multiple links such as rinsing, cleaning, anti-oxidation, and drying. The recycling and environmental protection design of the system not only makes it highly efficient in industrial production but also reduces resource waste, meeting the current environmental protection requirements. This system is particularly suitable for industries that require high-precision and high-efficiency processing of the surface of metal materials.

[0067] It should be noted that for a metal sheet flushing and antioxidant circulation system designed by the present invention, during use, after placing the metal sheet between two rows of conveying rollers 2, the two rows of conveying rollers 2 will axially roll to convey the metal sheet. At this time, the water supply valve 16 is started, and the water supply valve 16 pumps out the water in the clean water layer of the water tank 15. The clean water enters the spray pipe 17, and the spray pipe 17 starts to spray downward to spray and clean the metal sheet conveyed between the conveying rollers 2. The flushed sewage will fall into the sewage layer of the water tank 15 along the hopper 14 due to gravity. At this time, the metal sheet that is in contact with the brush roller 202 and the absorbent cotton roller 203 in the conveying roller 2 and is being dehydrated will undergo an oxidation phenomenon. The gas supply valve 5 of the gas cylinder 4 is started, and the inert gas in the gas cylinder 4 is introduced into the sealing cover 3 by the gas supply fan 6 along the exhaust pipe 7. The inert gas contacts the metal sheet to block the oxidation process. When the pressure sensor 8 gives an alarm, the exhaust valve 9 is started, and the exhaust valve 9 pumps out the inert gas in the sealing cover 3 and introduces it into the gas collecting cylinder 10. The gas in the gas collecting cylinder 10 enters the condenser 11, and the condenser 11 cools and condenses the water molecules in the inert gas into an inert liquid. The inert liquid flows along the infusion pipe 12 into the gas-liquid separator 13 to remove the water molecules. The sewage containing inert gas in the sewage layer of the water tank 15 will also flow into the gas-liquid separator 13 along the branch pipe of the infusion pipe 12. The gas-liquid separator 13 will separate the inert gas and water molecules from the sewage. The sewage will be discharged, and the inert gas is introduced into the gas cylinder 4 by the gas-liquid separator 13. Then the gas cylinder 4 will introduce the gas into the sealing cover 3 again, repeating the above process to complete the cycle.

[0068] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it is understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
