Calcined lime conveying system

Abstract

The invention discloses a calcined lime conveying system which comprises a fixed frame, a conveying main pipe and a dust collector, wherein the conveying main pipe is arranged on the fixed frame, one end of the conveying main pipe is connected with a hammering machine, the other end of the conveying main pipe is connected with the dust collector, and the dust collector is arranged on the top of a calcined lime cone. The technical scheme can effectively solve the technical problems that the failure rate of a cone pump is high, a gas lock is easily blocked, a gasifying plate of the cone pump is easily blocked, the conveying speed of calcined lime is low, and the conveying pipe is easily blocked; the cone pump system easily leaks gas, leaks lime and the like. The calcined lime conveying system also has the advantages of reduced cone pump air conveying links, low production failure rate, low running cost and convenience for maintenance. The production operation rate can be improved, the operation environments can be improved, and the equipment cost can be reduced. The calcined lime negative pressure conveying system requires low investment cost, has good use effect and remarkable economic benefits and can be broadly used for conveying broken calcined lime.

Description

technical field [0001] The invention belongs to the technical field of conveying equipment in metallurgical processes, and in particular relates to a conveying system for quicklime. 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. [0003] Currently, quicklime can be calcined in a Maerz kiln, where combustion air and limestone are ca...
