An automatic high temperature metal ash cooling and screening device

Abstract

The invention relates to an automatic high-temperature metal ash cooling and screening device. At least four bearing roller assembly devices on a machine frame are used for supporting a cooling tank. At least one pair of limiting support assembly devices are arranged on the edge of each bearing roller assembly device, and the limiting support assembly devices are used for limiting the cooling tank. A gear motor drives the cooling tank to rotate through chain wheels, and a screening tank of a screening part rotates synchronously. A cooling cover is fixedly arranged outside the cooling tank. An indirect water cooling system in the cooling cover is used for conducting horizontal spray cooling on the rotating cooling tank, and cooling water is recovered through the cooling cover. When the water level in a water level switch box at the bottom of the cooling cover reaches a high water level switch, a draining pump is started to work; when the water level reaches a lower water level switch, the draining pump stops working; after hot ash in the cooling tank is cooled through the indirect water cooling system, the cooling tank rotates reversely, cold ash is discharged towards the screening part by means of cooling blades in the cooling tank; the cold ash is classified into three kinds of particles with different particle sizes through the screening tank, and the cold ash with different particle sizes fall from corresponding outlets in a coarse-to-fine mode.

Description

technical field [0001] The invention relates to an automatic high-temperature aluminum ash super cooling and screening device, which belongs to the technical field of high-temperature metal ash cooling and screening. Background technique [0002] At present, the recovery of metal components from metal slag generally adopts the operation method of stirring the slag to separate the metal and ash components. After the metal component and the ash component are separated, the ash (mixed with a small amount of metal component) is usually transferred to a closed room for dumping by manual carts or forklifts. After being manually spread and dried, the temperature of the ash is slowly cooled from several hundred degrees to Ten degrees. After the ash is cooled, it will form a granular mixture of large and small pieces, which needs to be manually bagged and processed in the line. The above operation process not only has problems such as environmental pollution (high dust pollution), ...

AI Technical Summary

Problems solved by technology

The above operation process not only has problems such as environmental pollution (high dust pollution), low operation efficiency (complex procedures, long cooling time), but also endangers human health (high labor intensity, prone to silicosis, etc.)

In order to solve the defects of aluminum ash processing equipment, the Chinese utility model patent No. ZL201120470311.6 discloses a hot aluminum ash cooling and screening integrated machine. Indirect cooling of aluminum ash is realized by means of water, which can realize the separation of two kinds of particles of aluminum ash, but this utility model cannot recycle cooling water, resulting in waste of water resources, and the reliability and degree of automation are low
