Clean and environment-friendly iron wires galvanizing apparatus and its technology

Abstract

The invention relates to a clean and environment-friendly iron wires galvanizing apparatus and its technology. The iron wires galvanizing apparatus mainly comprises a paying-out machine (1), a polishing machine (2), a water tank (3), a first galvanizing tank (4), a second galvanizing tank (5), a third galvanizing tank (6), a cold water tank (7), a hot water tank (8) and a take-up machine (9), wherein, roller groups are provided on the paying-out machine (1), the polishing machine (2), the water tank (3), the first galvanizing tank (4), the second galvanizing tank (5), the third galvanizing tank (6), the cold water tank (7), the hot water tank (8) and the take-up machine (9), the iron wires of the paying-out machine (1) and the iron wires of the take-up machine (9) are connected end to endthrough each roller group. The invention also relates to a clean and environment-friendly iron wire galvanizing technology; the invention has the characteristics that no cyanogen or no pickling is contained, circulating water is not discharged which is clean and environment-friendly, the iron wires galvanizing apparatus provided in the invention can replace the traditional equipment of iron wiresgalvanizing, the invention has advantages of water saving and no environmental pollution, and the labor intensity of operators can be reduced, so that operators can get rid of work environment of strong acid mist, thereby the invention is capable of alleviating the damage of acid to operators body, reducing production cost of galvanizing iron wires and raising the competitiveness of enterprises.

Description

technical field [0001] The invention relates to a wire rod galvanizing equipment, in particular to a clean and environment-friendly iron wire galvanizing device and a process thereof. Background technique [0002] In the prior art, the iron wire galvanizing device and process, that is, pickling galvanized iron wire equipment and its process are as follows: [0003] [0004] Galvanized Iron Wire Step 5 includes: [0005] [0006] 1. In the prior art, a large amount of wire-drawing powder is used in step 1 cold drawing, and the flying wire-drawing powder in the production process permeates the air, and the dust formed seriously damages the respiratory system of workers. Because of this, most iron wire factories adopt open-air or semi-enclosed production methods, so that production has to be subject to the interference of weather and seasons; production cannot be performed in rainy and snowy weather, and workers in the north have to suffer from severe cold in winter. ...

Problems solved by technology

[0009] 4. In step 5a, the iron wire needs to be placed on the rotating reel, usually: each bundle of iron wire weighs 300-500 kg, each reel occupies an area of ​​about 1 square meter, and a total of 14 to 20 wires are required Workers need to move seven or eight tons of wire to the reels every day, and need to observe more than a dozen rotating reels at all times, and must shuttle back and forth between more than a dozen wire shelves. The labor intensity of the workers is high and the production efficiency is low. , new workers are incompetent, recruitment is difficult, and production costs are high

[0010] 5. In steps 5h and c, the water in the sink in the cleaning tank is constant flow water, and the water inlet is 3000m 3 The flow rate of / h continuously flows into the cleaning tank, and the overflowing sewage is not treated. Many manufacturers choose to secretly discharge it directly from the discharge port into the natural environment, causing groundwater pollution and causing great harm to the natural environment.

Both pre-plating and post-plating washing use running water. Every day, every production line discharges tens of tons or even hundreds of tons of used cleaning water, which not only discharges a large amount of sewage, but also greatly wastes water resources.
