Abstract
Description
Technical Field
[0001] This utility model relates to the field of iron tower production equipment, specifically designing a fume extraction hood for a galvanizing tank. Background Technology
[0002] Harmful fumes are generated during the galvanizing process, so these harmful fumes need to be sealed to prevent them from spreading into the environment. Existing fume hoods have the following problems: (1) poor sealing performance, fumes are easy to escape from the gaps in the hood, causing pollution to the working environment; (2) the lifting mechanism is bulky and inflexible in operation, affecting the daily maintenance and production efficiency of the galvanizing tank; (3) the overall structure is complex, and installation and disassembly are time-consuming, affecting equipment updates or adjustments. Summary of the Invention
[0003] This utility model aims to provide a fume extraction and dust removal hood for galvanizing tanks, with the specific solution as follows: A fume extraction hood for a galvanizing tank includes a galvanizing tank with track plates on both sides and two lifting hood mechanisms between the track plates. Each lifting hood mechanism includes a lifting curtain, which comprises several lifting curtain assemblies. Each lifting curtain assembly includes a crossbar and a shielding fabric. Several lifting curtain slides are provided on the track plates, and the lifting curtain slides and crossbars are arranged in a one-to-one correspondence.
[0004] One end of the lifting curtain is equipped with an I-shaped fixing frame, which fixes the first crossbar. Both ends of the I-shaped fixing frame are equipped with rope tensioning components. At the top, the two fixing frames can fit together better due to their I-shaped shape.
[0005] The rope stretching assembly includes a rope fixing end, a rope, and a rope stretching mechanism. The rope fixing end is installed at both ends of the I-shaped fixing frame, and the rope is located between the rope fixing end and the rope stretching mechanism.
[0006] The rope lifting mechanism is a winch, and a rope limiting cylinder is installed below the winch. The winch is existing technology and will not be described in detail. The rope limiting cylinder is to ensure that the rope is straight after entering the winch, so as to allow the winch above the rope limiting cylinder to work better.
[0007] The track plate is equipped with lifting curtain supports on both sides. The lifting curtain supports and the lifting curtain are configured to cooperate with each other. The lifting curtain supports include crossbar grooves, and the crossbar grooves and crossbars are configured one-to-one. This ensures that each crossbar is supported.
[0008] It also includes a top sealing mechanism, which is located on the top of the track plate. The top sealing mechanism includes a lifting cylinder, and a sealing component is provided at one end of the lifting cylinder.
[0009] The lower part of the sealing assembly includes a groove, and the I-shaped fixing bracket includes stop bars. The width of the groove matches the width of the two stop bars. This design ensures that harmful fumes are not leaked.
[0010] A sealing ring is provided between the stop bar and the groove, and the sealing ring is installed in the groove of the sealing assembly. This design can further achieve a seal.
[0011] This utility model discloses a fumigation and dust removal hood for galvanizing tanks. The crossbar can slide on the lifting curtain slide rail, and the crossbar is composed of several segments. A shielding fabric is set between the crossbars, so that when needed, the crossbar can be slid, and the shielding fabric can also rise together, thereby achieving the shielding of harmful smoke and dust (forming a closed space).
[0012] This utility model has the following advantages: 1. The enclosed space formed can efficiently capture harmful fumes generated during the galvanizing process, reducing environmental pollution.
[0013] 2. The top sealing mechanism drives the sealing components through a lifting cylinder. The width of the stop bar and the groove are precisely matched. Together with the built-in sealing ring, multiple sealing barriers are formed to effectively isolate harmful fumes and dust from leakage and ensure a safe working environment.
[0014] 3. The grooves on the horizontal bars of the lifting curtain bracket are set one-to-one with the horizontal bars to ensure that each horizontal bar is evenly supported, preventing deformation or failure caused by uneven force, and improving the durability of the overall device.

[0016] The following is combined Figures 1-5 To be further described: A fume extraction hood for a galvanizing tank includes a galvanizing tank 1, with track plates 2 on both sides of the galvanizing tank 1 and two lifting hood mechanisms 3 between the track plates 2. Each lifting hood mechanism 3 includes a lifting curtain 31, which includes several lifting curtain assemblies 32. Each lifting curtain assembly 32 includes a crossbar 33 and a shielding fabric 34. Several lifting curtain slides 21 are provided on the track plates 2, and the lifting curtain slides 21 and the crossbars 33 are arranged in a one-to-one correspondence.
[0017] One end of the lifting curtain 31 is equipped with an I-shaped fixing frame 35, which fixes the first crossbar 33. Both ends of the I-shaped fixing frame 35 are equipped with rope tensioning components 36. At the top, the two fixing frames, being I-shaped, can fit together better. The rope tensioning component 36 includes a rope fixing end 37, a rope 38, and a rope tensioning mechanism. The rope fixing end 37 is installed at both ends of the I-shaped fixing frame 35, and the rope 38 is located between the rope fixing end 37 and the rope tensioning mechanism. The rope tensioning mechanism is a winch, with a rope limiting cylinder 39 below the winch. The winch is existing technology and will not be described in detail. The rope limiting cylinder 39 ensures the rope is straight after entry, thus allowing the winch above the rope limiting cylinder 39 to operate better.
[0018] The track plate 2 is equipped with lifting curtain brackets 4 on both sides. The lifting curtain brackets 4 and the lifting curtain 31 are configured to cooperate with each other. The lifting curtain brackets 4 include crossbar grooves 41, and the crossbar grooves 41 and crossbars 33 are configured one-to-one. This ensures that each crossbar 33 is supported.
[0019] It also includes a top sealing mechanism 5, located on top of the track plate. The top sealing mechanism 5 includes a lifting cylinder 51, with a sealing component 52 at one end. The lower part of the sealing component 52 includes a groove 53, and the I-shaped fixing bracket 35 includes stop bars 351. The width of the groove 53 matches the width of the two stop bars 351. This design ensures no leakage of harmful fumes. A sealing ring is provided between the stop bars 351 and the groove 53, and the sealing ring is installed within the groove 53 of the sealing component 52. This design further enhances the sealing effect.
[0020] The winch is existing technology. Preferably, the winches are staggered, with the winch on the left and the lifting hood mechanism 3 on the right. This ensures that the I-shaped fixing frame 35 can fit together as closely as possible (e.g., Figure 5 Although the winch is not shown, it can be seen from the rope limit cylinder 39. In order to control the trajectory of the rope 38, several rope traction wheels are set on the track plate 2.
[0021] The galvanizing tank uses a fume extraction hood. In actual use, when sealing is required, the winch first operates to pull up the rope 38, thereby raising the I-shaped fixing frame 35 and lifting the first crossbar 33. Then, the covering fabric 34 and the next crossbar 33 covering fabric 34 are also lifted together. When the I-shaped fixing frame 35 reaches the top, one side of the two I-shaped fixing frames 35 is attached. Finally, the lifting cylinder 51 of the top sealing mechanism 5 descends and locks the groove 53 of the sealing component 52 into place with the two I-shaped fixing frames 35.
[0022] The above are merely preferred embodiments of the present utility model and are 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.
