【摘要】：皮帶機(jī)是工礦企業(yè)最常見的輸送設(shè)備。皮帶機(jī)具有技術(shù)相對成熟、運行成本低的優(yōu)勢,故在鋼鐵企業(yè)有更為廣泛的應(yīng)用。然而皮帶機(jī)技術(shù)發(fā)展到今天也并非已經(jīng)盡善盡美,本文以首鋼礦業(yè)公司燒結(jié)廠皮帶機(jī)運輸系統(tǒng)為研究對象,重點對皮帶機(jī)的優(yōu)化改造進(jìn)行了研究。本文的研究對皮帶機(jī)更好地在鋼鐵行業(yè)和其它行業(yè)的推廣、應(yīng)用具有重要的指導(dǎo)意義,特別是為鋼鐵企業(yè)進(jìn)一步降低皮帶機(jī)運行消耗提供了寶貴的經(jīng)驗。首先,對電機(jī)、運輸帶線層進(jìn)行了合理優(yōu)化。運用數(shù)學(xué)模型對全廠262條皮帶機(jī)電機(jī)功率進(jìn)行校核,并進(jìn)行統(tǒng)籌規(guī)劃,對六條皮帶機(jī)的電機(jī)進(jìn)行了優(yōu)化。通過對運輸帶品種進(jìn)行優(yōu)化將原有40種運輸帶品種壓縮為20種。為了降低運輸帶消耗,研究出一種非接觸式導(dǎo)料槽;該裝置徹底解決了運輸帶因欄板位置磨損而造成提前更換的問題。其次,對托輥及清料裝置進(jìn)行了研究。對托輥軸承配合和密封形式進(jìn)行了改進(jìn),對托輥安裝間距進(jìn)行了研究。為了降低皮帶機(jī)掉料清掃的勞動強(qiáng)度,研究出自動推料器、螺旋式增面輪自動推料器、螺旋式清掃器、豐字型下托輥,從減輕崗位勞動強(qiáng)度和減少現(xiàn)場掉料方面進(jìn)行了優(yōu)化改造。最后,對皮帶機(jī)接口進(jìn)行了研究。對比了常見的運輸帶接頭形式的優(yōu)、缺點,重點解決了斗提機(jī)鋼絲帶接口頻繁故障的問題,研制出新型斗提鋼絲帶接口,并取得了國家專利。
[Abstract]:Belt conveyor is the most common conveying equipment in industrial and mining enterprises.Belt conveyor has the advantage of relatively mature technology and low operating cost, so it is widely used in iron and steel enterprises.However, the development of belt conveyor technology has not been perfect until now. This paper takes the belt conveyor system of Shougang Mining Company as the research object, focuses on the optimization of belt machine transformation.The research in this paper is of great significance to the popularization and application of belt conveyor in iron and steel industry and other industries, especially it provides valuable experience for iron and steel enterprises to further reduce the running consumption of belt conveyor.First of all, reasonable optimization of motor and transport belt layer is carried out.In this paper, the motor power of 262 belt machines in the whole plant is checked by mathematical model, and the motor of six belt machines is optimized.By optimizing the variety of transport belt, the original 40 kinds of belt were compressed to 20 kinds.In order to reduce the consumption of transport belt, a non-contact guide tank is developed, which solves the problem that the transport belt is replaced in advance due to the wear of the fences.Secondly, the roller and cleaning device are studied.The fit and seal of roller bearing were improved, and the mounting distance of roller was studied.In order to reduce the labor intensity of material dropping cleaning of belt conveyor, the automatic material pushing device, the spiral adding surface wheel automatic pushing device, the spiral cleaning device, and the abundant type lower roller are studied.In order to reduce the labor intensity of the post and reduce the material drop on the spot, the optimization reform was carried out.Finally, the interface of belt machine is studied.In this paper, the advantages and disadvantages of common transport belt joints are compared, and the problems of frequent faults of steel wire belt interface of bucket lift machine are mainly solved, and a new type of bucket lift steel wire belt interface is developed, and the national patent has been obtained.
