A quicklime delivery system

Abstract

The invention discloses a quick lime conveying system which comprises a lime kiln, a conveying machine, a crushing machine, a separation screen, a high-position material cabin, a measuring funnel and a material tube, wherein an underground receiving cabin is arranged at the bottom of the lime kiln; one end of the conveying machine is arranged inside the underground receiving cabin; the other end of the conveying machine is arranged at the top of the crushing machine; the crushing machine, the separation screen, the high-position material cabin and the measuring funnel are sequentially connected through the material tube; an ash preventing room is arranged outside the crushing machine and the separation screen; and a draft fan is arranged on the ash preventing room. The quick lime conveying system which is provided by the invention is used for screening lime and removing dust out of lime after lime is crushed; and the quick lime conveying system is simple in structure and convenient to use.

Description

technical field [0001] The invention belongs to the technical field of material conveying, and in particular relates to a quicklime conveying system. Background technique [0002] In metallurgical processes such as steelmaking and ironmaking, in order to adjust the alkalinity of sinter, it is necessary to add quicklime to the sintering ingredients, and quicklime has become one of the necessary raw materials. The heat released by the digestion of quicklime with water can increase the temperature of the material, which is beneficial to the sintering. Calcium hydroxide is produced after the quicklime is digested. Calcium hydroxide is a kind of colloid with viscosity, which can roll the concentrate into small balls, which makes the raw materials have good air permeability, is beneficial to sintering, and improves sintering output and quality. Currently, quicklime can be calcined in a Maerz kiln, where combustion air and limestone are calcined in the calcination zone and mixed ...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, quicklime is calcined in a lime kiln, conveyed by a belt, crushed by a hammer machine, and then transported to the finished product warehouse through a conveying system. In addition, a large amount of dust will be generated during the lime crushing process, which will pollute the air, and the working environment of the staff will become poor.
