Mixing-type lime kiln capable of quickly cooling and discharging

Abstract

The invention relates to the field of lime production, in particular to a mixing-type lime kiln capable of quickly cooling and discharging. The mixing-type lime kiln comprises a kiln body, wherein a partition plate is arranged in the kiln body, the partition plate is provided with a plurality of through holes used for allowing a finished lime product to pass through, the partition plate is arranged on the lower side of a fire grate, a cooling cavity is formed between the fire grate and the partition plate, a collecting cavity is formed in the lower side of the partition plate, an air outlet pipe is arranged on the side wall of the cooling cavity, an air supplying device is connected to the air outlet pipe, thus the finished lime product falling from the fire grate into the cooling cavity is cooled through air input by the air outlet pipe, the temperature of the finished lime product falling into the collecting cavity is decreased quickly, the finished lime product is collected, transferred and used conveniently, and workers are also prevented from being scalded by the high-temperature finished lime product; and meanwhile, air guided into the upper part of the fire grate is heated by the finished lime product, dispersed by the fire grate and can evenly enter raw materials on the upper part of the fire grate, normal and even burning of fuel on the upper part of the fire grate ismaintained conveniently, conducting of the calcination process is promoted, and the calcination time is reduced.

Description

technical field [0001] The invention relates to the field of lime production, in particular to a mixing type lime kiln for rapid cooling and discharging. Background technique [0002] As an important auxiliary material in industrial production, lime is widely used in many industries such as metallurgy, chemical industry, environmental protection, building materials, etc. At present, the commonly used mixing type lime kiln for preparing lime generally uses coal, coke and other solid fuels to calcinate limestone to prepare lime. The current mixing The type lime kiln generally adopts the structure of kiln top feeding and kiln bottom ash discharge. The interior of the kiln body is a space structure connected from top to bottom. The mixed fuel and limestone are thrown on the grate through the material distribution mechanism, The air is introduced into the lower side of the grate to maintain the combustion of the fuel, so that the fuel is calcined limestone to prepare lime, and ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is: for the currently commonly used mixing type lime kiln, the collecting tank for collecting finished lime products is integrally connected with the inner space of the kiln body, resulting in a high temperature of finished lime products output from the ash discharge port, which is not conducive to subsequent collection and transfer. It is also easy to cause technical problems of staff burns, and a mixing type lime kiln with rapid cooling and discharging is provided
