Abstract

The invention provides a device and method for recovering iron in steel and iron industrial wastewater. The device comprises a recovery device shell; a first partition plate is horizontally arranged in the recovery device shell; the upper part of the first partition plate is provided with a recovery cavity, and the lower part of the first partition plate is provided with a water inlet cavity; a water inlet is formed in the upper part of the water inlet cavity, and a water outlet is formed in the lower part of the water inlet cavity; the water outlet is provided with a first filter screen; at least one recovery assembly is at least arranged in the recovery device shell; and the recovery assembly comprises an upper synchronous pulley, a lower synchronous pulley, a synchronous pulley and a recovery mechanism. The device is simple in operation, and the recovery efficiency is greatly increased.

Description

technical field [0001] The invention relates to an iron recovery device, in particular to an iron recovery device and method in iron and steel industry wastewater. Background technique [0002] In the production of some iron and steel industries, manual operations are usually used to salvage the iron in the wastewater from the hot water tank, which is not only labor-intensive, but also low in efficiency, and the labor cost is high, and it also causes a waste of iron resources. [0003] Patent 201220539330.4 discloses an iron recovery device in iron and steel industry wastewater. A hole with a diameter of 2 cm is respectively opened on the rear half of the front plate and the rear half of the rear plate. The vertical distance between the center of the hole and the edge of the plate is 5cm, the main shaft (7) runs through these two holes, tighten the lock nuts on both ends of the main shaft. The wheels and blades are alternately installed on the main shaft, and the magnets ar...
