Uniform distribution device for lime kiln

Abstract

The invention relates to a uniform distribution device for a lime kiln. The uniform distribution device mainly comprises a feeding device, a transmission device and a discharge device, wherein the feeding device mainly comprises a feeding hopper, a taper hopper I and a discharge opening I; the discharge device mainly comprises three connecting frames, a distributing hopper and a flange; the flange at the opening of the discharge device is connected with a flange at the bottom of the discharge opening I of the feeding device through a bolt; the three connecting frames are arranged at the lower part of the flange; one ends of connecting frames are welded to the flanges and are distributed in a triangular way; the other ends of the connecting frames are connected with the distributing hopper; the distributing hopper adopts a taper surface structure; a circular platform is arranged at the upper part of the distributing hopper; the transmission device mainly comprises a bearing platform, a motor, a gear I, a gear II, a disc I, a bearing, a disc II and a base. The uniform distribution device realizes uniform distribution of the lime kiln, enables material to directly and uniformly drop onto the lime kiln plane, reduces the labor intensity of workers, is simple in overall operation and flexible to rotate, and has high efficiency and practicability.

Description

technical field [0001] The invention mainly relates to the technical field of lime kilns, in particular to a lime kiln uniform distribution device. Background technique [0002] The main component of limestone is calcium carbonate, and the main component of quicklime is calcium oxide. The basic principle of burning quicklime from limestone is to use high temperature to decompose calcium carbonate in limestone into quicklime (calcium oxide) and carbon dioxide; the process is as follows: limestone and fuel are loaded into lime The kiln starts to decompose at 850°C after preheating, and completes calcination at 1200°C. After cooling, it discharges through the bottom of the lime kiln to complete the production of quicklime products. [0003] The old-fashioned lime kiln relies entirely on manpower to load the prepared pulverized coal and stone from the kiln top discharge device. The dust and noise are loud and the pollution is serious. The new lime kiln is mainly composed of the ...

[0003] The old-fashioned lime kiln relies entirely on manpower to load the prepared pulverized coal and stone from the kiln top discharge device. The dust noise is loud and the pollution is serious. The new lime kiln is mainly composed of a kiln body, a discharge device, a combustion device, and ash It is composed of equipment, electrical appliances, instrument control devices, dust removal devices, etc. Relatively speaking, the discharge device is the most important device, because it requires the fuel and limestone to be in uniform contact when they are loaded into the kiln at the same time. For a good calcination effect, uniform contact must be carried out through the distribution device to balance the resistance in the furnace, and strive to burn evenly throughout the furnace section. Therefore, the form and use of the distribution device have a great impact on the production efficiency of the lime kiln. Now there are Various distributors, including rotary distributors, conch-type distributors, fixed distributors, etc., and these distributors are characterized by being able to distribute lime material in general, but they cannot be arranged uniformly and reasonably. Make the lime distribution consistent, and the unreasonable distribution of lime will lead to impenetrable burning during the combustion process, and will make one side of the lime kiln heavier, which will reduce the service life of the kiln in the long run, and cannot realize efficient and rational production of the lime kiln.
