Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, specifically to a hot-dip galvanizing protective device with a nano-coating structure. Background Technology

[0002] In modern hot-dip galvanizing processes, workpieces need to be immersed in a hot-dip galvanizing bath. When the workpieces are immersed in the galvanizing bath, the reaction produces metal fumes, which can seriously damage the health of production personnel and have an adverse impact on the surrounding environment.

[0003] Therefore, in modern hot-dip galvanizing production, in order to protect the health of production personnel, flue gas diversion devices are often installed on the galvanizing tank, and the galvanizing tank is sealed with a hood. However, after long-term use, this type of protective equipment will have the problem of wall adhesion, causing corrosion of the hood and flue gas passage. To address this problem, at present, a nano-coating can be applied to the contact parts of the hot-dip galvanizing flue gas to play an isolation role. However, as the power unit of the flue gas passage, the fan side is not protected, and it is very easy for the fan structure to be corroded by the flue gas. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a hot-dip galvanized protective device with a nano-coating structure, enabling contactless flow of flue gas throughout the entire process and avoiding fan corrosion problems.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a hot-dip galvanized protective device with a nano-coating structure, including a lifting air guide hood, wherein a connecting pipe port is provided on the lifting air guide hood, and a telescopic pipe is connected to the connecting pipe port, characterized in that a control flue is connected to the telescopic pipe, and a non-contact air guide control component is provided on the control flue.

The guide channel has an upward inclined slope structure, with its upper and lower ends located above the center of the control flue and the center of the guide pipe, respectively.

[0008] The non-contact air guiding control component also includes a protective slot, which is located on the outside of the guide channel. The air guiding fan is connected to the protective slot, and a liquid-cooled heat exchanger is installed inside the protective slot. The air outlet of the air guiding fan is aligned with the liquid-cooled heat exchanger and the guide channel. The air is cooled by the liquid-cooled heat exchanger and then enters the guide channel.

[0009] Preferably, the lifting air guide hood is a frustum-shaped hood, and the connecting pipe is located at the top center of the lifting air guide hood.

[0010] Preferably, the connecting pipe port is connected to the bottom end of the telescopic pipe via a pair of flange plates.

[0011] Preferably, the inner wall of the guide pipe is also coated with a nano-anti-corrosion coating. Both the guide pipe and the flow channel are connected to the control flue.

[0012] Preferably, a dustproof net is provided on the protective slot.

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] like Figure 1-3As shown, the hot-dip galvanizing protective equipment with a nano-coating structure includes a lifting air hood 1. The lifting air hood 1 can be equipped with a lifting guide rod, which guides the lifting air hood 1 to move up and down, thereby fastening it to the galvanizing tank and sealing the top opening of the galvanizing tank. The lifting air hood 1 is provided with a connecting pipe 2. Preferably, the lifting air hood 1 is a truncated pyramidal hood, and the connecting pipe 2 is located at the top center of the lifting air hood 1. The structure is simple and convenient for production.

[0021] Connecting pipe 2 is connected to telescopic pipe 3. The bottom ends of connecting pipe 2 and telescopic pipe 3 are connected by a pair of flange plates for easy disassembly and assembly.

[0022] The telescopic pipe 3 is connected to the control flue 4. The telescopic pipe 3 serves to connect the lifting air guide hood 1 and the control flue 4, and also matches the movement of the lifting air guide hood 1. The inner walls of the lifting air guide hood 1, the telescopic pipe 3, and the control flue 4 are all coated with a nano anti-corrosion coating. In order to prevent corrosion by galvanizing fumes, a non-contact air guide control component is installed on the control flue 4. The non-contact air guide control component can be used to guide and discharge galvanizing fumes without the fumes coming into contact with the fan.

[0023] The non-contact air guiding control component includes an air guiding fan 5, which is a blower. The control flue 4 has an L-shaped structure. The air guiding fan 5 is mounted at the top of the vertical section of the control flue 4. A guide channel 6 is provided at the top of the control flue 4, and a guide pipe 7 is provided on the outlet side of the guide channel 6. The guide channel 6 has an upward-sloping structure. The upper slope of the guide channel 6 is located above the center of the guide pipe 7. The lower slope is located at the center of the control flue 4. Both the guide pipe 7 and the guide channel 6 are connected to the inside of the control flue 4. The inner wall of the guide pipe 7 is also coated with a nano-anti-corrosion coating to improve the protection effect against galvanizing fumes. The air outlet of the air guiding fan 5 faces the guide channel 6.

[0024] The control flue 4 adopts an L-shaped structure and the discharge position is set above the control flue 4. The guide channel 6 corresponds to the guide pipe 7. The guide fan 5 is a blower. The high pressure generated by the guide fan 5 is used to control the flow channel on one side. The guide channel 6 adopts an inclined bevel structure and extends to one side of the guide pipe 7. The slope of the guide channel 6 is located at the upper center of the guide pipe 7. The high-speed air entering the guide pipe 7 increases the air velocity at the top of the control flue 4, making the pipe opening side of the guide pipe 7 in a negative pressure state. Since the control flue 4 is an L-shaped structure, under the smoke flushing effect, the flue gas enters the guide pipe 7 and is discharged.

[0025] The non-contact air guiding control component also includes a protective slot 8, which is located on the outside of the guide channel 6. The air guiding fan 5 is connected to the protective slot 8, and a liquid-cooled heat exchanger is installed inside the protective slot 8.

[0026] In the specific implementation process, in order to make full use of the chimney effect, a liquid-cooled heat exchanger is installed on the protective slot 8 to liquid-cool the air introduced by the air guide fan 5. This lowers the temperature of the flue gas upon contact with the air, and due to the reduced temperature, condensation easily occurs, causing some water vapor to condense and be discharged, further increasing the negative pressure on the discharge side. During this process, the air guide fan 5 does not come into contact with the flue gas, maximizing equipment protection. A dustproof net 9 is installed on the protective slot 8. The air discharged from the air guide fan 5 enters the protective slot 8 after passing through the dustproof net 9, and the protective net is used to filter the air.

[0027] The liquid-cooled heat exchanger includes a heat pipe 10, which is installed in a protective slot 8. The air outlet of the air blower 5 is aligned with the heat pipe 10. The heat pipe 10 is an S-shaped pipe with both ends passing through the protective slot 8. The two ends of the heat pipe 10 are respectively connected to an upper water connector 11 and a lower water connector 12. The upper water connector 11 and the lower water connector 12 are connected to an external circulation device. Cold water is pumped into the heat pipe 10 through the upper water connector 11. The heat pipe 10 makes full contact with the air supplied by the air blower 5 to cool the air. The water after heat exchange is discharged through the lower water connector 12.

[0028] Through the collaborative design of L-shaped control flue 4 and non-contact air guiding control components, the high-speed airflow generated by the fan, combined with the slope structure of the guide channel 6, forms a negative pressure effect, realizing non-contact air guiding of flue gas throughout the entire process, avoiding fan corrosion problems. A liquid-cooled heat exchanger is integrated in the protective slot 8, which enhances the chimney effect through condensation. The entire process is covered with a nano anti-corrosion coating, solving the problems of severe corrosion and frequent maintenance of traditional flue gas emission equipment.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
