Description

Technical Field

[0001] The invention relates to the technical field of hot-dip galvanizing equipment, and in particular to an impact-type hot-dip galvanizing remelting zinc ash device and an operating method. Background Art

[0002] The pure zinc content in zinc ash is about 80% or more. Metallic zinc has a high economic value, so it is necessary to recover metallic zinc from it. Most of the metallic zinc in zinc ash can be recovered by "distillation" or "dissolution". When processing zinc ash, metallic zinc melts and precipitates from ZnO (zinc oxide) solid. Recover as much metallic zinc as possible. After the zinc ash is formed, it should be recycled as soon as possible. Otherwise, the zinc ash will change over time, which will seriously affect the recovery of zinc, because the longer the zinc is stored, the more it will be oxidized in the air.

[0003] At present, remelting zinc ash is widely done manually, using tools to press the zinc ash into a pot for reuse, which is laborious, inefficient, and unsafe. Alternatively, the zinc ash is collected and smelted separately, such as patent CN 102181664A, which requires additional smelting equipment and is costly. Alternatively, the zinc ash is collected and separated, such as patent CN 207567319 U, which also requires additional smelting equipment and other equipment, which is costly. The advantage of this treatment is that solid metallic zinc can be obtained, but it will also increase energy consumption and cost. Summary of the invention

The lifting drive motor 2-1 drives the screw lift 2-2 to operate, lift or lower relative to the support sleeve 2-3, and then adjust the height of the dust-removing mechanism 3.

[0033] The bracket 3-3 is double-layered, with a reciprocating drive motor 3-1 installed on the upper layer, a driving shaft 3-7 installed in the middle of the lower layer, and driven shafts 3-9 installed on both sides of the driving shaft 3-7.

[0034] A crank mechanism 3-5 is installed on the driven wheel, and a limiting wheel mechanism 3-6 is installed at the lower end of the crank mechanism 3-5. The limiting wheel mechanism 3-6 includes a cross bar 3-6-2, a vertical bar 3-6-1 and limiting wheels 3-6-3 at both ends of the vertical bar 3-6-1. The cross bar 3-6-2 is installed at the lower end of the crank mechanism 3-5, and vertical bars 3-6-1 are installed on both sides of the cross bar 3-6-2.

[0039] The working principle of the present invention is:

[0040] This device uses the "dissolution method" to recover metallic zinc. When in use, this device is parked above the platform on one side of the zinc pot where zinc ash is stored. When it is needed, the control cabinet is operated, and the walking mechanism 1 is operated to drive the device to move on the track arranged along the direction of the zinc pot until it straddles the zinc pot where zinc ash is stored. At this time, the lifting mechanism 2 is operated to make the ash beating mechanism 3 descend, and the zinc ash isolation plate 5 is simultaneously lowered to below the zinc ash liquid surface to isolate the zinc ash and zinc liquid, and prevent the zinc ash from moving to the zinc liquid side during ash beating; then the ash beating mechanism 3 is operated to beat the zinc ash liquid surface. When this device is running, the reciprocating drive motor 3-1 causes the crank mechanism 3-5 to reciprocate, and the ash beating grids 3-8 on both sides are used alternately to press the zinc ash into the zinc liquid, forcing the metallic zinc in the zinc ash to remelt, thereby realizing the recovery of metallic zinc. After the beating is completed, the ash beating mechanism 3 stops operating, and the device is lifted by the lifting mechanism 2, so that the zinc ash isolation plate 5 leaves the zinc ash liquid surface and is higher than the zinc pot platform. Finally, the walking mechanism 1 is operated to move the entire device out of the zinc pot.
