High-temperature slag screening device for slag cooler

Abstract

The invention provides a high-temperature slag screening device for a slag cooler, which is applied to the technical field of slag cooler for cooling high-temperature metallurgical slag. The high-temperature slag screening device is characterized in that a plurality of screening rollers (2) are arranged on a rack (1); a gap part is reserved between every two adjacent screening rollers (2); a plurality of rollers (3) are arranged on each screening roller (2); the screening rollers (2) are connected with motors (24); a multi-hole screen mesh (13) is formed by the screening rollers (2) and the rollers (3) on the screening rollers (2); and the high-temperature slag screening device is arranged over a feed opening of the slag cooler. The high-temperature slag screening device provided by the invention is simple in structure and low in manufacturing cost, can segregate and screen the high-temperature slag in advance according to the particle sizes of the slag before the slag enters the slag cooler, meanwhile ensures the operating time that the screening device can continuously separate the high-temperature slag in a high-temperature environment, is free from the problem of blockage of the screen mesh, is improved in working efficiency and is prolonged in service life.

Description

technical field [0001] The invention belongs to the technical field of a slag cooling machine for cooling metallurgical high-temperature slag, and more specifically relates to a high-temperature slag screening device for a slag cooling machine. Background technique [0002] In the metallurgical industry, the temperature of the high-temperature slag in the semi-molten state is generally as high as 1200 ° C to 1500 ° C, the thermal insulation performance is very good, and the cooling speed is slow. Therefore, the rapid cooling of high temperature slag is the key to its resource utilization. At present, slag cooling machines (such as roller slag cooling machines) are used in various industries, and most of the cylinders of the drum slag cooling machines are designed with separate warehouses and multiple lifting plates. This structural design can greatly improve the slag heat exchange effect of the drum slag cooling machine. In order to avoid the impact wear and smashing damage...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is: aiming at the deficiencies of the prior art, to provide a simple structure, low manufacturing cost, which can pre-isolate and screen the high-temperature slag before entering the slag cooler according to the particle size, so as to ensure that it meets the particle size. The high-temperature slag enters the slag cooler, and the high-temperature slag exceeding the particle size will be screened and separated. At the same time, it can ensure that the screening device can continuously separate the high-temperature slag in a high-temperature environment without the problem of screen blockage, which improves work efficiency and use.
