Device for collecting zinc smoke of hot-dip galvanizing workshop

Abstract

The invention discloses a device for collecting zinc smoke of a hot-dip galvanizing workshop and relates to a smoke collecting device. The device comprises a dust collecting cover body fixed on a travelling crane; two load lifting hooks of a crane are hooked by virtue of a vertical guide rope which passes through a cover body rack from top to bottom; the cover body can be used for moving and fetching workpieces with the crane; the fixed device part is supported and guided by upright stands which are distributed on four corners of a zinc pot; for movable baffle plates at the two sides in the length direction of the zinc pot, when the workpieces are soaked in zinc bath, the movable baffle plate at the outer side ascends, so that the top of the movable baffle plate at the outer side is in butt joint with the lower end of the cover body, and the bottom of the movable baffle plate at the outer side is aligned to the top of the movable baffle plate at the inner side, so that the space above the workpieces and the zinc pot is sealed, and thus, the smoke dust is prevented from escaping; meanwhile, the zinc ash on the surface of the zinc bath is prevented from being taken away, so that the zinc consumption is saved; when the zinc ash is scrabbled, the movable baffle plate at the inner side ascends, so that space is made for convenience in operation; when the workpieces are fetched, the movable plates are descended for convenience in conveying the workpieces.

Description

technical field [0001] The invention relates to a smoke collection device, in particular to a zinc smoke collection device in a hot-dip galvanizing workshop. Background technique [0002] At present, the hot-dip galvanizing industry mostly uses the conventional zinc ammonium chloride fluxing solution as the fluxing agent, and it is unavoidable to generate a large amount of zinc fume during the hot-dip galvanizing process; due to the high temperature of the flue gas generated by galvanizing, the The speed is fast, and the zinc oxide dust volatilized on the zinc liquid surface is taken away in large quantities, causing environmental pollution and increasing the cost of galvanizing; the smoke and zinc dust in the flue gas of the galvanizing process are separately treated and collected, which can save the cost of galvanizing and increase the cost of galvanizing. Reduce environmental pollution, so widely used. [0003] Since there is a crane running above the zinc pot, in or...

Problems solved by technology

The disadvantages of this fixed cover collection system are: it is often necessary to clean the dust powder of the movable parts in the cover under high temperature environment; the working vision is poor, and the galvanizing operation is slightly inconvenient; it is difficult to remove slag;

[0005] Ordinary hood-type dedusting mechanism must maintain the effective hoisting space of the crane. The center of gravity of the hood is far from the supporting point. When the hood weighing several tons moves with the crane, a slight collision may cause deformation and damage to the moving parts of the hood; The working time is longer and the galvanizing operation is inconvenient
