Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of industrial waste gas purification and treatment equipment, and specifically relates to hot-dip galvanizing fume absorption equipment. Background Art
[0002] Hot-dip galvanizing is also called hot-dip galvanizing and hot-dip galvanizing: it is an effective metal corrosion protection method, mainly used in metal structural facilities in various industries. It is to immerse the rust-removed steel parts in molten zinc liquid at about 500℃ to make a zinc layer adhere to the surface of the steel components, thereby achieving the purpose of corrosion protection. The hot-dip galvanizing process flow: finished product pickling - water washing - adding auxiliary plating solution - drying - hanging plating - cooling - chemical treatment - cleaning - polishing - hot-dip galvanizing completion. Hot-dip galvanizing is developed from the older hot-dip method. Since France applied hot-dip galvanizing to industry in 1836, it has a history of more than 170 years. In the past 30 years, with the rapid development of cold-rolled strip steel, the hot-dip galvanizing industry has been able to develop on a large scale.
[0003] Due to the working mode of hot-dip galvanizing, a large amount of particles mainly composed of ammonium chloride will be generated when the metal components are immersed in the melt, and eventually emitted in the form of smoke. However, the traditional smoke removal method cannot effectively absorb the zinc smoke floating in the middle of the galvanizing pool. Especially for some large galvanizing pools, the traditional smoke removal method is even less effective. Summary of the Invention
[0004] (1) Technical problems solved
[0005] In view of the shortcomings of the existing technology, the present invention provides a hot-dip galvanizing fume absorption equipment, which solves the problem that due to the working mode of hot-dip galvanizing, a large amount of particles mainly composed of ammonium chloride will be generated when the metal components are immersed in the melt, and eventually emitted in the form of smoke. The traditional smoke removal method cannot have a good absorption effect on the zinc smoke floating in the middle of the galvanizing pool, especially for some large galvanizing pools, the smoke removal effect of the traditional smoking method is even less ideal.
[0006] (2) Technical solution
[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions: a hot-dip galvanized fume absorption device, comprising a mounting cover, an exhaust fan, a motor base and a servo motor, wherein two mounting plates are provided inside the mounting cover, and the two mounting plates are slidably connected to the inner side wall of the mounting cover, and the side walls on opposite sides of the two mounting plates are fixedly connected to a transmission shaft, the motor base is located between the two mounting plates, the driving end of the servo motor passes through the bottom of the motor base and extends to the bottom thereof and is fixedly connected to a driving wheel. A transmission wheel is provided on both sides of the driving wheel, and the two transmission wheels are meshed with the driving wheels. The bottom center positions of the two transmission wheels are fixedly connected, and the ends of the two transmission rods away from the transmission wheels are fixedly connected to the fixing plates, and the two fixing plates are fixedly connected to the inner side wall of the mounting cover, and the outer surfaces of the two transmission rods are fixedly sleeved with a transmission cylinder, and the outer surfaces of the two transmission cylinders are provided with a transmission groove, and the ends of the two transmission shafts away from the mounting plate are respectively slidably engaged in the inside of the two transmission grooves.
[0008] Preferably, the two transmission grooves are respectively distributed around the outer surface of the transmission cylinder to ensure that the mounting plate can perform periodic motion continuously.
[0009] Preferably, two locking screen plates are provided at the bottom of the mounting plate, the top of the locking screen plate located above is fixedly connected to the bottom of the mounting plate, and an absorbent cloth is provided between the two locking screen plates to achieve the first level of impurity removal and smoking effect.
[0010] Preferably, mounting grooves are provided on the side walls of the two locking screen plates on opposite sides and near the edges, and locking springs are installed inside the two mounting grooves to facilitate replacement of the absorbent cloth between the two locking screen plates.
[0011] Preferably, two limiting sieve plates are provided above the locking sieve plate, and both limiting sieve plates are fixedly connected to the side walls of the mounting plate. An activated carbon absorption layer is filled between the two limiting sieve plates, which plays the second and most important smoke removal effect.
[0012] Preferably, a partition plate is fixedly connected to the top of the mounting plate, and both sides of the partition plate are slidably connected to the inner side wall of the mounting cover, thereby achieving the final smoking effect.
[0013] Preferably, an air inlet corresponding to the exhaust fan is provided on the top of the mounting cover to provide an air source for the entire device.
[0014] Working principle: The equipment is installed just above the galvanizing pool. When in use, start the exhaust fan and servo motor, and the smoke will flow to the inside of the installation cover under the strong exhaust action of the exhaust fan. At the same time, the driving end of the servo motor drives the driving wheel to rotate, and the two transmission wheels meshing with the driving wheel are driven. At this time, the transmission rod fixedly connected to the bottom of the driving wheel and the transmission cylinder fixedly sleeved on its outer surface also rotate, and the mounting plate is slidingly connected to the inner side wall of the mounting cover, and the two transmission shafts fixedly connected to the side wall opposite to the two mounting plates, and the ends away from the mounting plates are respectively slidably engaged in the inside of the transmission groove. When the two traditional cylinders rotate, they will drive the two mounting plates to make periodic back and forth motion in the vertical direction, and then drive the locking screen plate at the bottom of the mounting plate and the locking screen plate above the locking screen plate. The activated carbon absorption layer performs the same movement, thereby improving the absorption efficiency of particulate matter when the smoke passes through the absorption cloth and the activated carbon absorption layer. Unlike the traditional static absorption method, the dynamic absorption of the absorption cloth and the activated carbon absorption layer will not only improve the absorption efficiency of the smoke, but also improve the utilization rate of the absorption cloth and the activated carbon absorption layer. The two locking screen plates are provided with mounting grooves on the side walls on the opposite side and near the edge. Locking springs are installed inside the two mounting grooves. This arrangement makes it easier to replace the absorption cloth between the two locking screen plates. When the smoke is transferred upward through the limiting screen plate, it is stirred by the traditional cylinder, traditional wheel and driving wheel, and then passes through the partition plate for the last particle absorption, which effectively ensures that the particle content of the exhaust gas meets the requirements and further reduces the content of particulate matter in the flue gas.

When the two traditional cylinders rotate, the two mounting plates are driven to perform periodic reciprocating motion in the vertical direction, and then the locking screen plate at the bottom of the mounting plate and the activated carbon absorption layer above the locking screen plate are driven to perform the same motion, thereby improving the absorption efficiency of particulate matter when the smoke passes through the absorption cloth and the activated carbon absorption layer. Unlike the traditional static absorption method, the dynamic absorption of the absorption cloth and the activated carbon absorption layer not only improves the absorption efficiency of the smoke, but also improves the utilization rate of the absorption cloth and the activated carbon absorption layer.
