Material separating device used for rotary kiln preheater

Abstract

The invention discloses a material separating device used for a rotary kiln preheater. The material separating device comprises a charge hole, a material bin, an unloading plate and discharge holes, wherein the material bin is semispherical; the charge hole is formed in the top of the material bin; the unloading plate is arranged on the bottom of the material bin; the discharge holes are formed in the unloading plate, and a sealed area on the unloading plate extends upwards to form a plurality of tapered bumps; and materials pass through the charge hole, are in contact with the tapered bumps and the unloading plate, and are discharged from the discharge holes. The material separating device can reduce direct contact among the materials, the material separating device body and the unloading plate to reduce abrasion of the material separating device, so that the service life is prolonged; and moreover, uniform discharge and thermal treatment of the materials can be realized.

Description

technical field [0001] The invention relates to a material distribution device, in particular to a material distribution device for a rotary kiln preheater. Background technique [0002] Distributing devices are ubiquitous in industrial production processes, among which distributing devices are required in the hopper of the rotary kiln preheater used for firing activated lime. After sieving, the limestone that meets the particle size requirements enters the silo of the preheater through transport machinery and chutes. The common material distribution device is bell-shaped and has a single structure, which makes it difficult to make the material feeding and preheating uniform. A material distributing device is installed in the preheater silo of the rotary kiln, and the material enters the preheating belt through the outlet of the material distributing device and the butt joint chute for further processing. [0003] Due to reasons such as the hot air pipe of the preheater an...

AI Technical Summary

Problems solved by technology

[0003] Due to the hot air pipeline of the preheater and the thermal radiation heat of the rotary kiln, etc., the working environment temperature of the material distribution device in the rotary kiln preheater is often high, and the long-term direct contact between the material and the cutting plate of the material distribution device is likely to cause separation. The wear of the material device, and the heat accumulation of the material is not easy to evenly enter the next process for processing
