Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of hot-dip galvanizing equipment, and in particular to an automatic alarm carbon dioxide fire extinguishing device for the hot-dip galvanizing machine head. Background Technology
[0002] Hot-dip galvanizing involves immersing cleaned and activated steel products in molten zinc. Through the reaction and diffusion between iron and zinc, a zinc alloy coating with good adhesion is deposited on the surface of the steel products.
[0003] After hot-dip galvanizing, the workpiece needs to be centrifuged at high speed in a zinc-spinning basket to remove excess molten zinc from the surface. The clamping and releasing device of the zinc-spinning basket is controlled by hydraulic oil. These devices are all located inside the enclosed head of the hot-dip galvanizing zinc pot, which is a high-temperature environment. After centrifugation, the temperature of the molten zinc reaches 400-500℃. If the molten zinc comes into contact with the wiring and oil circuit, or if there is an oil leak at the oil pipe interface or an oil pipe rupture and leaks, the oil can come into contact with the zinc-spinning basket or the molten zinc, which can easily cause a fire in the enclosed head of the hot-dip galvanizing zinc pot. Furthermore, oil fires are difficult to extinguish, causing significant economic losses, and it takes about 15 days to resume production after a fire.
[0004] In the process of implementing this embodiment, the inventors discovered at least the following problems:
[0005] The existing hot-dip galvanizing machine head with its enclosed zinc pot is prone to internal fires that are difficult to extinguish, potentially causing significant economic losses and requiring a long time to resume production. Utility Model Content
[0006] The purpose of this utility model is to provide an automatic alarm carbon dioxide fire extinguishing device for hot-dip galvanizing machine heads, which solves the technical problem that existing hot-dip galvanizing machine heads with enclosed zinc pots are prone to internal fires that are difficult to extinguish, causing significant economic losses and requiring a long time to resume production.
[0007] Utility model solution:
[0008] This utility model provides an automatic alarm carbon dioxide fire extinguishing device for hot-dip galvanizing machine heads, including a hot-dip galvanizing machine head, a fire extinguishing mechanism, and an automatic control mechanism. The hot-dip galvanizing machine head includes a machine head enclosure, a zinc-slinging frame tensioning device, and a zinc-slinging frame. The zinc-slinging frame tensioning device is located inside the machine head enclosure, and the zinc-slinging frame is detachably connected to the tensioning device. The fire extinguishing mechanism includes a carbon dioxide fire extinguisher and several nozzles. The nozzles are fixedly installed on the top of the inner wall of the machine head enclosure, and the carbon dioxide fire extinguisher is connected to the nozzles.

The nozzle 220 is connected; the automatic control mechanism 300 includes a monitoring probe 310, a control component 320, a nitrogen cylinder 330, a gas solenoid valve 340, and a release valve 350; the monitoring probe 310 is installed inside the head enclosure 110 and is electrically connected to the control component 320; the gas solenoid valve 340 is connected to both the control component 320 and the nitrogen cylinder 330; the release valve 350 is connected to the carbon dioxide fire extinguisher 210 and is also connected to the gas solenoid valve 340; the control component 320 is electrically connected to a buzzer alarm 360 and an alarm light 370.
[0028] Specifically, the hot-dip galvanizing head 100 is used to move the workpiece into the zinc bath for galvanizing; the head enclosure 110 is used to enclose the galvanizing working environment; the galvanizing frame 130 is used to fix the workpiece; and the galvanizing frame tensioning device 120 is used to clamp or loosen the galvanizing frame 130, facilitating the installation of the workpiece onto the galvanizing frame 130 and then onto the galvanizing frame tensioning device 120; the fire extinguishing mechanism 200 is used to deliver carbon dioxide to the nozzle 220, thereby releasing carbon dioxide for fire extinguishing; and the automatic control component 320 is used to monitor... The device controls the opening and closing of the carbon dioxide fire extinguisher 210. The monitoring probe 310 is used to detect the fire situation inside the head enclosure 110. After detecting the fire situation, it sends a signal to the control unit 320. The control unit 320 opens the gas solenoid valve 340 and activates the buzzer alarm 360 and alarm light 370 to notify the operators.
