This invention proposes an automatic galvanizing device for iron towers, comprising a housing, a first support frame slidably mounted on the housing, a material frame movably mounted on the first support frame, a first driving component detachably mounted on the housing, the first driving component being connected to the first support frame via a transmission mechanism, an
elastic component being provided between the second support frame and the gas collecting
pipe, a first lever fixedly mounted on the first support frame, and a second lever fixedly mounted on the gas collecting
pipe. The beneficial effects of this invention are: the first driving component drives the material frame to move to the right along the housing, and the first and second levers cooperate to drive the gas collecting
pipe and the material frame to move synchronously, quickly collecting the
waste gas generated during the galvanizing process, achieving the function of rapid
waste gas collection, preventing direct emission of
waste gas and causing
pollution, while reducing
energy consumption and improving galvanizing efficiency.
