Automatic magnetic slag conveyor of rotational flow well

Abstract

The invention discloses an automatic magnetic slag conveyor of a rotational flow well. The automatic magnetic slag conveyor is provided with a transmission mechanism for longitudinally communicating an opening of the rotational flow well with the bottom of the rotational flow well, and a plurality of conical grooves connected with the transmission mechanism, so that the conical grooves sequentially pass through the bottom of the rotational flow well for collecting scales, the conical grooves collecting the scales automatically operate to the opening of the rotational flow well under the control of a computer and through the rotation of the transmission mechanism, the scales at the bottom of the rotational flow well are automatically collected and cleared, the scale clearing efficiency is increased by above 30 percent, and a large quantity of labor force is saved. According to the characteristic that the scale in cooling water is magnetic, the conical grooves are set to be in a magnetic grid shape, so that the scales are attracted in the conical grooves through a magnetic force; the conical grooves are recycled after automatically discharging the scales when reaching the opening of the rotational flow well under the magnetic control of the computer on the conical grooves. The automatic magnetic slag conveyor has the advantages of energy and labor saving effects, good scale clearing effect, and high work efficiency.

Description

technical field [0001] The invention relates to the technical field of steel rolling wastewater treatment, in particular to an automatic magnetic slag removal machine for a swirl well. Background technique [0002] In the process of steel rolling, the rolling mill bearings, rolls, etc. need to be cooled by water, and the iron sheet groove needs to be washed by water. The used water contains a large amount of iron oxide scale. For every ton of steel smelted, more than 17 kg of iron oxide scale is produced. These oxide scales are absolutely Most of them enter the water, making the content of suspended solids in the water as high as several thousand mg / L. Therefore, the cooling water can not only be used directly, but also cannot be discharged directly according to environmental protection requirements. Therefore, the steel rolling system needs water treatment and circulation facilities. [0003] The swirl well is a vortex type sedimentation tank, which is widely used in iron ...

AI Technical Summary

Problems solved by technology

[0004] The problem of iron scale cleaning in swirl wells has always been a bottleneck restricting production. The usual method is to accumulate the scale at the bottom of the swirl well after a certain period of time and then grab it out of the well with a slag grabber and return it to the steelmaking process for recycling. The whole process requires a lot of manpower to complete. This traditional method of iron scale cleaning not only wastes a lot of time, manpower and material resources, but also has a very bad impact on the sanitation of the working environment.
