Description

Technical Field

[0001] This utility model relates to the field of zinc fume treatment technology, and in particular to a zinc fume treatment device for galvanizing tanks. Background Technology

[0002] During galvanizing operations, a large amount of zinc fumes are generated in the galvanizing bath. The core function of the zinc fume treatment device is to effectively collect, purify, and treat these zinc fumes. Zinc oxide contained in zinc fumes can cause symptoms such as fever, chills, cough, and chest tightness. In severe cases, it can also damage the respiratory system and lung function. By collecting and purifying zinc fumes, the treatment device can significantly reduce the concentration of zinc fumes in the workshop air, preventing operators from inhaling excessive amounts of harmful dust and reducing the risk of occupational diseases from the source. If zinc fumes accumulate in the workshop, they will form an irritating odor, reduce visibility, affect workers' vision and work comfort, and may even reduce employee work enthusiasm due to the harsh environment.

[0003] However, existing technologies, such as Chinese Publication No. CN108707955A, "A Zinc Fume Treatment Device for a Galvanizing Pool," provide a zinc fume treatment device for a galvanizing pool, including a galvanizing chamber, a zinc fume absorption chamber, zinc fume ducts, a transparent observation chamber, and a zinc fume absorption tower. The galvanizing chamber includes a galvanizing pool, a zinc pool guardrail, a blower, a zinc fume shielding device, and a blower duct. The zinc pool guardrail is located on both sides of the galvanizing pool; the blower is located on one side of the galvanizing pool; the zinc fume shielding device is located above the galvanizing pool; the blower duct is located below the zinc pool guardrail and fixed to both sides of the galvanizing pool; the zinc fume absorption chamber is located on the side of the galvanizing pool without the blower; the transparent observation chamber is located on the opposite side of the zinc fume absorption chamber relative to the galvanizing pool; and the absorption tower is located on the opposite side of the transparent observation chamber relative to the galvanizing pool. This invention provides a zinc fume treatment device for a galvanizing pool that effectively treats the zinc fumes generated during galvanizing, while simultaneously allowing for effective observation of the galvanizing status of the workpiece through the transparent observation chamber, enabling adjustments to the process as needed.

[0004] However, this device lacks a flip-top fumigation structure, which prevents it from quickly covering the area above the galvanizing tank when workpieces are immersed or removed. It also prevents the fumigation port from getting closer to the source of zinc fumes, increasing the amount of fumes diffusing into the workshop environment. Furthermore, it cannot create a relatively enclosed local space, nor can it guide the fumes towards the exhaust port of the fumigation device. This causes the fumes to escape due to turbulent airflow, reducing the collection rate, increasing restrictions on the operating path of hoisting equipment, leading to malfunctions due to equipment collisions, and making it inconvenient for workers to observe the operation within the zinc tank. Utility Model Content

[0005] The purpose of this invention is to solve the problems existing in the prior art, such as the inability to quickly cover the area above the galvanizing tank when the workpiece is immersed or removed, the inability to bring the fume extraction port closer to the source of zinc fumes, the increase in the amount of zinc fumes diffusing into the workshop environment, the inability to form a relatively enclosed local space, the inability to guide the zinc fumes to the exhaust port of the fume extraction device, the resulting escape of fumes due to airflow turbulence, the reduction of collection rate, the increased restriction on the running path of hoisting equipment, the resulting malfunctions due to equipment collisions, and the inconvenience for workers to observe the operation in the zinc tank.

[0024] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0025] This invention features a flip-top fumigation structure that quickly covers the area above the galvanizing tank opening when a workpiece is immersed in or removed from the galvanizing tank. This brings the fumigation port closer to the source of zinc fumes, reducing the amount of zinc fumes diffusing into the workshop environment. It creates a relatively enclosed local space, guiding the zinc fumes towards the exhaust port of the fumigation device. This prevents the fumes from escaping due to turbulent airflow, improves the collection rate, reduces restrictions on the operating path of hoisting equipment, avoids malfunctions caused by equipment collisions, and facilitates workers' observation of the operation within the zinc tank.

Then the maintenance door 21 can be opened to maintain or replace the filter plate 20 inside.

[0038] Working principle: When the workpiece descends into the galvanizing tank body 1, the hydraulic rod 6 performs work, pushing the first crank 5, causing the shaft 3 to rotate inside the bearing seat 2. The smoke cover 4, which rotates with the shaft 3, flips as the workpiece descends. To prevent zinc fumes from overflowing, the external power supply of the motor 11 is activated. The motor 11 is fixed to the outer surface of the exhaust pipe 9 by the fixing rod 10. After the motor 11 is powered on, it drives the fan blade assembly 12 to rotate. The rotating fan blade assembly 12 generates wind and drives airflow, creating negative pressure inside the processing shell 8 and the negative pressure hose 7. Zinc fumes flow through the negative pressure hose 7 and the processing shell 8. When the zinc fumes enter the processing shell 8, they are stopped by the stop sealing plate 19. The internal filter plate 20 performs filtration, and the final treated flue gas is discharged through the exhaust pipe 9. When the filter plate 20 needs maintenance and replacement after long-term use, the rocker arm 25 can drive the worm gear 23 to rotate inside the protective shell 24. Under the meshing action of the worm gear 23 and the worm wheel 22, the rotating rod 13 will be driven to rotate inside the processing shell 8. The second crank 14, which rotates with the rotating rod 13, will drive one end of the connecting rod 15. The other end of the connecting rod 15 will push the clamping frame 16 and the limiting block 17 to move along the slotting direction of the limiting groove 18, and make the clamping frame 16 move away from the stop sealing plate 19. Then the maintenance door 21 can be opened to maintain and replace the internal filter plate 20.
