Description

Environment-friendly galvanization pot capable of preventing flue gas from overflowing
Technical Field
The invention belongs to the field of hot galvanizing belt processing devices, and relates to a galvanized pot, in particular to an environment-friendly galvanized pot capable of preventing flue gas from overflowing.
Background
Hot galvanizing is also called hot dip galvanizing and hot dip galvanizing, is an effective metal corrosion prevention mode, and is mainly used for metal structure facilities in various industries. The rust-removed steel strip is immersed in molten zinc at about 500 ℃ to adhere a zinc layer to the surface of a steel member, so that the aim of corrosion prevention is fulfilled.
Because galvanized steel strip is galvanized through high-temperature zinc liquid, the temperature of the steel strip leaving the zinc pot is high, and after the steel strip leaves the zinc pot, part of the zinc liquid on the surface of the steel strip can react with oxygen in the air to form zinc oxide due to the gradual decrease of the external temperature, and part of the zinc liquid with high temperature can react with the steel strip to form zinc-iron alloy, which can affect the quality of the steel strip and the galvanized layer. Therefore, after the steel strip leaves the zinc liquid surface, the steel strip needs to be cooled so as to reduce side reactions after the galvanized steel strip leaves the zinc pot. However, the existing galvanized pot lacks a cooling function and cannot meet the requirement on improvement of the galvanization quality. And, during the galvanization reaction, white flue gas is generated, and if the flue gas is not treated, the environment of a workshop is polluted, and the health of workshop workers is threatened.

The galvanized pot has compact structure, does not occupy redundant workshop space, is beneficial to the layout in workshops, and can be used by only hanging the cooling mechanism on the edge of the galvanized pot body. After the steel belt sent out of the zinc liquid level is wiped, air-dried and cooled, the occurrence of side reaction can be effectively avoided, and the galvanization quality is improved.
2. This can prevent environment-friendly galvanized pot that flue gas is excessive designs to domatic structure through the bottom surface that wears the dress shell, and this structure can be conveniently by the tight pulley, the zinc liquid backward flow that extrudes on the regulating wheel is internal to the galvanized pot, makes things convenient for the recovery of zinc liquid.
3. This can prevent excessive environmental protection type galvanized pot of flue gas through designing the expansion plate into the adjustable extending structure of length, makes it can satisfy the different length galvanized pot body and wear the cover requirement in dress shell interval space, guarantees closing cap quality, avoids the diffusion of flue gas.
4. The invention has the advantages of scientific and reasonable design, improved galvanization quality, safety, environmental protection and easy realization, and is an environment-friendly galvanization pot with higher innovation and capability of preventing flue gas from overflowing.
