Full automatic control lime shaft kiln production line

Abstract

The invention discloses a full automatic control lime shaft kiln production line comprising a shaft kiln, a material loading system, a material distributing system and an ash discharging system, wherein the material loading system comprises a mixed hopper, a limestone storehouse, a first belt type conveyor for conveying limestone, a coal storehouse and a second belt type conveyor for conveying coal; the material distributing system comprises a material distributing device arranged on the top of the shaft kiln; and the ash discharging system comprises a cooling device arranged in the shaft kiln and a plurality of ash scrabbling machines arranged on the bottom of the shaft kiln. By utilizing the full automatic control lime shaft kiln production line, on premise of ensuring low cost and high maneuverability, raw material mixed proportion can be conveniently regulated and controlled, lifting of hopper is convenient and reliable, and the lifting efficiency is high. Shaft kiln material face is divided to four small area blocks by revolving the material distributing device, materials are distributed uniformly on three line faces and seven point faces, and therefore, material face in the kiln is uniform, and the roasting stability is improved. By utilizing the full automatic control lime shaft kiln production line, seal of kiln bottom is ensured, fuel is saved, and power consumption is saved.

Description

technical field [0001] The invention relates to calcium carbonate production equipment, in particular to a fully automatic control lime shaft kiln production line. Background technique [0002] Due to the vertical setting of the vertical kiln, its feed port is generally at the top of the kiln. It is necessary to mix the raw limestone and fuel coal under the kiln and then lift it to the top of the kiln for feeding, or directly set the height of the limestone bin and the coal bin to the same height as the kiln. top height match; [0003] The former has high transportation costs for limestone and coal, and it is difficult to control the mixing ratio, and its stability and reliability are restricted during the lifting process, while the latter is obviously more expensive, with higher manufacturing difficulty and higher use costs; [0004] Moreover, in the material distribution process, due to the constraints of the position of the material distribution head and the structure of...

AI Technical Summary

Problems solved by technology

The ash discharge system of the existing lime shaft kiln production line generally uses the ash removal machine and the ash discharge machine directly. Due to the limitation of the kiln bottom structure, the sealing effect is not good enough, and the stability of the vertical kiln material level drop is not high enough.
