Raw material limestone and bunker coal are prepared with vibratory blanking machine discharging, ribbon conveyer conveying, measuring chute and are sufficiently mixed under kiln by the present invention in proportion, adopt titled bridge type truck feeder to take turns to promote two mixed-hoppers to kiln crown simultaneously, under ensureing the premise of low cost and high operability, can conveniently regulating and controlling Raw Material Blending Ratio, and bunker lift is convenient and reliable, raising efficiency is high；Shaft kiln charge level is divided into 4 block of cells by rotated distributing device simultaneously, and 3 line faces, 7 some faces carry out uniform cloth, so that charge level is uniform in kiln, improves calcination stability；Kiln bottom charge level is also divided into the small ash chamber that several faces are extremely connected with kiln body by some machine ash discharges of scratching in the ashes by the present invention, vibration dust unloadnig apparatus ash discharge is joined again through hydraulic pressure push-pull valve, ensure that from face shaft kiln charge level uniformly declines, ensure that the sealing in kiln bottom portion simultaneously, not only save fuel but also save power consumption。
The innovation that the present invention possesses:
1. full-automatic operation controls dispensing employing PLC control system, touch screen operation, automatic weighing, uniform dispensing, accurately metering, significantly reduces the labor intensity of workman, reduces recruitment, improve working environment, and make limekiln achieve datumization management, Automated condtrol。This system has automatic catch and manual gear two kinds, easy to operate。2. raw material limestone and bunker coal are prepared with special equipment under kiln and are sufficiently mixed by balance loaded vehicle feeding, even feeding, revolving fixed point cloth in proportion, skew bridge truck material-uploading style is adopted to be promoted to kiln crown, shaft kiln charge level is divided into 4 block of cells by rotated distributing device, 3 line faces, 7 some faces carry out uniform cloth, so that charge level is uniform in kiln, calcination is stably served critical effect。3. rationally air feed, seal ash discharge (1), reasonable air feed: active lime shaft kiln is in calcination process, the size of air feed and cloth wind uniformity coefficient, yield and quality to Calx are most important, inclined burning is arisen that as air feed is uneven, so that making burning and raw burn phenomenon occur, the quality of Calx thus can be largely effected on。The air feed system of my company design be by wind through aerator enter square air compartment and intake adit send into energy-conservation all pressures blast cap of my company's designed, designed all press, in the entrance kiln all measured, all pressure blast cap may insure that the layer distributed of combustion air science is to the section of furnace charge in required kiln, airstream in kiln is made to be evenly distributed, flame combustion intensity is consistent, air-flow, gas pressure distribution are scientific and reasonable, are effectively increased the activity degree and limekiln production yields that produce Calx。(2), uniform ash discharge is sealed: after Calx carries out cooling zone after shaft kiln calcination, have to be cooled down in time, can ash discharge after ash temperature is down to about 50 degree, thus the air quantity blasted in kiln there being strict control requirement, the sealing property of kiln bottom ash discharge equipment there is higher standard, it is ensured that blast the effective wind rate in kiln and disclosure satisfy that the requirement of cooling。My company's lime vertical kiln ash-discharging device have employed divides into the small ash chamber that 4 faces are extremely connected with kiln body by machine of the scratching in the ashes ash discharge of four drawer shapes by kiln bottom charge level, vibration dust unloadnig apparatus ash discharge is joined again through hydraulic pressure push-pull valve, ensure that from face shaft kiln charge level uniformly declines, ensure that the sealing in kiln bottom portion simultaneously, not only save fuel but also save power consumption。
Environmental protection facility qualified discharge
Lime vertical kiln environment protection standard is the policy of national set compulsory execution。The carbon dioxide gas mixture containing dust of its calcining and decomposing passes through air compressor, through rotation net dedusting, the flue dust of larger particles is separated, all reclaim after washing then through dehydration backwater for calcium carbonate carburizing reagent use, the periodic cleaning after sedimentation tank precipitates of the precipitate after washing；The dust produced in ash discharge process all reclaims entrance cloth bag by dust-removal cloth-bag, stops dust from flying。
Effect acquired after the invention process:
1. formulate a whole set of complete shaft kiln post operation code
1.1. kiln operation control procedure is dried
1.2. kiln rule of operation is opened
1.3. shaft kiln abnormal conditions and fault handling operation code
1.4. kiln, envelope kiln rule of operation are stopped
1.5. limekiln maintenance, inspection operation code have been formulated
1.6. limestone procedure for analysis
1.7. limekiln safe practice rule of operation
2. have employed full-automatic PLC automatic control system, operator only need to start the run switch of computer desktop, operates from being fed to ash discharge overall process without physical work, and whole service process shows all through screen, simply just reflect kiln condition clearly, thus greatly reducing labor intensity；Whole service process is only equipped with an operative employee and manipulates, and improves labor efficiency。
3. promote hopper and adopt frequency control and diffuse-reflectance sensor, it is ensured that hopper safety in lifting process, greatly reduce and rush to summit and the generation of landing phenomenon；
4. lime quality is greatly improved。Activity of Lime is brought up to more than 350 by the 280～320 of ordinary shaft kiln, and maturing rate is brought up to more than 92% by 85-90%, and energy consumption also declines to a great extent simultaneously, and the coal consumption of ton product is dropped to 135-140Kg by original 150Kg, and year saves coal more than 500 ton, extra earning more than 50 ten thousand yuan。
5. all electromechanical equipments adopt Frequency Converter Control, total installation of generating capacity 150KW, nearly 300,000 KW of year using electricity wisely, direct economic benefit more than 20 ten thousand yuan。
