Disc dehydration unit

Abstract

The invention discloses a disc dehydration unit which comprises a central column (3) and a rotating cylinder (12) which rotates around the central column (3), wherein a plurality of sieve hoppers (15) are arranged in the rotating cylinder (12) and a sieve plate (11) which can automatically close and open is connected to the bottom of each of the sieve hoppers (15). According to the disc dehydration unit, the design is reasonable, the structure is simple, the failure rate is low, the overhaul is convenient, and the service life is long. Water slag dehydration time is long, the moisture content of product slag is low, and the unit is applicable to various blast furnaces, no sewage is discharged, and the unit is environment-friendly.

Description

technical field [0001] The invention relates to a dehydration device, in particular to a water quenching slag treatment dehydration device. Background technique [0002] Metallurgy, chemical industry, non-ferrous metals and other industries generally use water quenching to treat slag, and drum dehydration devices have become the absolute mainstream. But at present, when the drum type dehydrator rotates once for dehydration, a batch of granulated slag is dehydrated, and its real dehydration time is less than half of the dehydrator's one-week time. Generally, the dehydrator rotates at 1 revolution per minute, so the dehydration time is less than For 30 seconds, the dehydration effect of the granulated slag is not good, and the moisture content of the finished slag reaches more than 30%. [0003] In addition, the rotation of the drum dehydrator requires a large amount of power, generally reaching hundreds of kilowatts, and the power consumption is relatively large. Moreover, ...

But at present, when the drum type dehydrator rotates once for dehydration, a batch of granulated slag is dehydrated, and its real dehydration time is less than half of the dehydrator's one-week time. Generally, the dehydrator rotates at 1 revolution per minute, so the dehydration time is less than 30 seconds, the dehydration effect of the granulated slag is not good, and the moisture content of the finished slag reaches more than 30%

[0003] In addition, the rotation of the drum dehydrator requires a large amount of power, generally reaching hundreds of kilowatts, and the power consumption is relatively large.

Moreover, when the dehydrator unloads slag, there is relative movement between the slag and the dehydrator. Since the frequency of slag unloading in the drum type dehydrator is very high, the wear on the dehydrator is relatively severe, and the life of the dehydrator is short.
