Hot dip galvanizing equipment with smoke prevention and dust control thermal insulation device

Abstract

The invention discloses hot dip galvanizing equipment with a smoke prevention and dust control thermal insulation device, which belongs to the technical field of metallurgy. The equipment is used for closing a pot mouth when a plating article is immerged into a zinc liquid to stop the zinc liquid from splashing outward and drawing away harmful flue gas instantaneously produced in a pot at the same time. The equipment consists of cover plate vehicles for closing the pot mouth, an exhaust duct, a cover plate vehicle driving mechanism, an electric control device and a supporting frame, wherein aplurality of groups of the cover plate vehicles are oppositely arranged on both sides of the pot mouth, and are supported by pack wheels arranged on the frame; and the front end of the exhaust duct is connected with an exhaust opening on the zinc pot below cover plates, the middle part of the duct is provided with a fan, and the rear end of the duct is connected with a smoke prevention and dust control device. The equipment has the advantages that: when the plating article approaches the liquid level, the pot mouth is closed, and the fan is started to ensure that the splashed zinc liquid is stopped in the pot and the harmful flue gas is prevented from diffusing outward; the equipment reduces the heat loss of the zinc pot; and the equipment completely solves the troublesome problems of serious pollution and high energy consumption existing in galvanizing production under the condition of not affecting process flow.

Description

technical field [0001] The invention belongs to the technical field of metallurgy, and in particular relates to hot-dip galvanizing equipment for environmental protection, emission reduction and consumption reduction. Background technique [0002] Solvent method hot-dip galvanizing is widely used in our country and even countries in the world. When the plated parts are put into and removed from the zinc pot, they need to be suspended by cranes. In addition, the dipping time is short, and the plated parts are frequently put in and out of the pot. Therefore, Open-mouth immersion plating is a common method, but it is very harmful to the environment. One disadvantage is: when the plated parts are immersed in the zinc solution, a large amount of harmful smoke and gases such as zinc chloride, hydrogen chloride, and ammonium chloride will be produced, and the exposed zinc pot will be allowed to spread, seriously polluting the surrounding environment. The second harm is: when the p...

Problems solved by technology

[0005] The object of the present invention is to provide a hot-dip galvanizing equipment with a smoke-eliminating, dust-removing and heat-preserving device, which is used to close the mouth of the pot when the plated parts are about to be immersed in the zinc solution, to prevent the zinc solution from splashing outwards, and to block the diffusion of smoke and dust at the same time. All the harmful smoke and dust generated in the pot can be completely removed for environmental protection, which can more effectively reduce the heat loss of the zinc pot and solve the problems of heavy pollution and high energy consumption in the production process of hot-dip galvanizing
