Rapid cooling and discharging device for rotary kiln roasting furnace burden

Abstract

The invention relates to the field of furnace burden cooling devices, in particular to a rapid cooling and discharging device for rotary kiln roasting furnace burden. The rapid cooling and discharging device comprises a main body, a modelling mechanism is arranged in the main body, a conveying mechanism is arranged on the main body, the conveying mechanism extends to the outside of the main body, and a cutting mechanism is erected on the conveying mechanism; and the conveying mechanism is provided with a feeding mechanism, the cutting mechanism drives the feeding mechanism, and the conveying mechanism is provided with a cooling mechanism. Through the arrangement of the modelling mechanism, roasting materials can be conveniently shaped, and the roasting materials can be conveniently stacked and stored in the later period; materials are cut conveniently through the arrangement of the cutting mechanism, so that the length size of the single materials is stipulated; the conveying mechanism is driven conveniently through the arrangement of the feeding mechanism to achieve ratchet wheel feeding, enough time is reserved for cutting of the cutting mechanism, and it is guaranteed that a cutting opening is tidy; and through the arrangement of the cooling mechanism, it can be guaranteed that cooling water is recycled while the materials are cooled, and waste of water resources is avoided.

Description

technical field [0001] The invention relates to the field of charge cooling devices, in particular to a rapid cooling and discharging device for the roasting charge of a rotary kiln. Background technique [0002] Roasting refers to heat treatment in air or inert gas flow at a certain temperature, also known as calcination. In the roasting metallurgical process, roasting not only makes the material chemically suitable for subsequent operations, but also provides a suitable physical state. Rotary kiln refers to a rotary calciner, a thermal equipment for heating bulk or slurry materials. [0003] However, the roasted materials out of the kiln are generally in the form of irregular agglomerates after cooling, and the irregular shape is not convenient for later stacking and finishing, and it puts higher requirements on storage conditions, which is not convenient for later transfer , the input cost is high, and most of the traditional devices use to spray a large amount of cooli...
