A boiler for galvanizing metal

Abstract

The invention discloses a boiler used for metal zinc dipping. The boiler comprises a boiler body, wherein a heating assembly (2) is arranged on the boiler body (1), a zinc smoke absorbing device (3) is further arranged on the side wall of the boiler body (1), and the boiler body (1) is a square groove (11) formed in the ground. The upper end of the boiler body (1) is open, a heat conduction layer (12), a casting layer (10), a supporting layer (13), a heat insulation layer (14) and a concrete layer (15) are sequentially arranged from inside to outside on the side wall of the square groove (11), an inner wall protective plate (16) is arranged on the inner side wall of the heat conduction layer (12), a protective wall steel plate (17) is buried into the upper portion of the concrete layer (15), and a top sealing plate (18) is arranged between the protective wall steel plate (14) and the inner wall protective plate (16). The boiler has the advantages of being high in heating efficiency, saving energy and being environmentally friendly.

Description

technical field [0001] The invention relates to a boiler used for galvanizing metal components, in particular to a boiler used for galvanizing metal components. Background technique [0002] In the hot-dip galvanizing process, in order to prevent the workpiece to be plated from directly entering the plating solution for galvanizing, the surface will be corroded by the plating solution, resulting in uneven surface, reducing the bonding force between the substrate and the coating, and affecting the subsequent process. People usually place the workpiece to be plated in the galvanizing solution before coating the metal layer on the workpiece to obtain a fine and uniform zinc layer with low porosity, strong binding force, good physical and chemical stability. Protection, especially on steel structures such as signal base stations, transmission towers, power towers, and communication towers, in order to ensure their service life and avoid corrosion of steel components, it is neces...

AI Technical Summary

Problems solved by technology

[0003] When galvanizing, the zinc block needs to be melted, and the existing heating method usually uses an iron pot for external heating, which has low heating efficiency, and the service life of the iron pot is short, usually 2 years, so it is necessary to The iron pot is constantly replaced, which makes the cost higher, which is not conducive to the long-term development of the enterprise
