Description

Technical Field

[0001] This utility model relates to the field of air purification and circulation technology, and in particular to an air purification and circulation system for a hot-dip galvanizing workshop. Background Technology

[0002] Hot-dip galvanizing is a process in which molten metal reacts with an iron substrate to create an alloy layer, thus bonding the substrate and the coating. The process begins with pickling the steel parts to remove iron oxide from their surface. After pickling, the parts are cleaned in an aqueous solution of ammonium chloride or zinc chloride, or a mixture of both, before being immersed in the hot-dip galvanizing bath. Hot-dip galvanizing offers advantages such as uniform coating, strong adhesion, and long service life. Air purification and circulation systems are typically installed in hot-dip galvanizing workshops.

[0003] In existing technologies, most traditional air purification circulation systems use fans to circulate air. However, the fans in these systems are usually fixed inside the system. This design makes it inconvenient to disassemble and reassemble the fans, as the process is cumbersome and time-consuming. Furthermore, it makes it difficult to repair or replace the fans when they are damaged, thus reducing the practicality of the air purification circulation system. Utility Model Content

[0025] By configuring the unit 1, air outlet duct 2, air inlet duct 3, exhaust fan 4, intake fan 5, air pump 6, exhaust pipe 7, air supply pipe 8, air purifier 9, mounting slot 10, fixing frame 11, fixing block 12, mounting bracket 13, slider 14, mounting frame 15, locking block 16, locking slot 17, mounting bolt 18, fixing bolt 19, drive motor 20, rotating rod 21, and valve plate 22, the system enables quick and convenient disassembly and assembly of exhaust fan 4 and intake fan 5.

[0026] Dustproof components are provided at both ends of the body 1. The dustproof components include mounting bases 23. Mounting bases 23 are fixedly installed on the side wall of one end of the body 1. A positioning rod 24 is fixedly installed on the side wall of the mounting base 23 away from the body 1.

[0027] By setting up the mounting base 23, positioning rod 24, dustproof net 25, fixing bracket 26, positioning block 27 and limiting bolt 28, the function of dust prevention for air outlet duct 2 and air inlet duct 3 is realized. By covering the openings of air outlet duct 2 and air inlet duct 3 with dustproof net 25, dust in the air is prevented from entering the interior of air outlet duct 2 and air inlet duct 3, avoiding dust from affecting the normal operation of air purification circulation system, and further improving the practicality of air purification circulation system.

[0028] Working Principle: When in use, the air purification and circulation system has the unit 1 mounted on the workshop wall, and the air purifier 9 installed inside the workshop. It operates in three modes: Exhaust Mode: The air purifier 9 is off, and the air inlet duct 3 is closed under the action of valve plate 22, keeping the outlet duct 2 unobstructed. The exhaust fan 4 is activated, and when the exhaust fan 4 is running, air is exhausted from the workshop through the outlet duct 2. Intake Mode: The air purifier 9 is off, and the air outlet duct 2 is closed under the action of valve plate 22, keeping the intake duct 3 unobstructed. The intake fan 5 is activated, and when the intake fan 5 is running, it completely purifies the air. In the circulation mode, both the air inlet duct 3 and the air outlet duct 2 are closed under the action of the valve plate 22. The exhaust fan 4, air pump 6 and air purifier 9 can be turned on. The exhaust fan 4 draws the air in the workshop into the air outlet duct 2, and then the air pump 6 introduces the air into the air supply duct 8 through the exhaust pipe 7. Then the air supply duct 8 sends the air into the air purifier 9, which purifies the air. The purified air is then discharged back into the workshop. In all three modes, the air passes through the dust filter 25 when it flows, and the dust filter 25 blocks the dust in the air.

[0029] When repairing or replacing the fan, first loosen the fixing bolt 19 so that it extends away from the fixing frame 11. After the fixing bolt 19 separates from the fixing block 12, release the fixing block 12. Then pull the fixing block 12 so that it slides out of the fixing frame 11, simultaneously causing the mounting bracket 13 to slide out of the mounting groove 10. The slider 14 slides inside the groove. After the mounting bracket 13 slides out of the mounting groove 10, remove the exhaust fan 4 or intake fan 5 from the body 1 together. Then loosen the mounting bolt 18 on the mounting bracket 13 so that the mounting... Bolt 18 extends away from mounting bracket 13. After mounting bolt 18 separates from mounting frame 15, the fixing of mounting frame 15 is released. Then, mounting frame 15 is pulled so that mounting frame 15 slides outward inside mounting bracket 13. The locking block 16 slides inside the locking groove 17. After mounting frame 15 slides out of mounting bracket 13, the exhaust fan 4 or intake fan 5 is disassembled. At this time, exhaust fan 4 or intake fan 5 can be repaired or replaced. After exhaust fan 4 or intake fan 5 is repaired or replaced, the above operation is reversed to reinstall exhaust fan 4 or intake fan 5 into the machine body 1.

[0030] When dustproofing the air outlet duct 2 and air inlet duct 3, first, put the dustproof net 25 onto the outer surface of the positioning rod 24. Then, move the fixing bracket 26 close to the mounting base 23 so that the positioning block 27 is aligned with the positioning groove. Next, move the fixing bracket 26 to put it onto the outer surface of the mounting base 23, and the positioning block 27 slides into the interior of the positioning groove. After the fixing bracket 26 is completely put onto the outside of the mounting base 23, press and fix the dustproof net 25. Then, tighten the limiting bolt 28. After the limiting bolt 28 penetrates the outer wall of the fixing bracket 26 and inserts into the side wall of the mounting base 23, fix the fixing bracket 26 to complete the installation of the dustproof net 25. Repeat the above operation to install the dustproof net 25 on the other end of the body 1 to complete the dustproofing of the air outlet duct 2 and air inlet duct 3. Reverse the above operation to remove the dustproof net 25. After the dustproof net 25 is removed, it can be cleaned or replaced.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
