JLY3809機(jī)立窯（加料及窯罩部件）設(shè)計(jì)

摘要：本課題完成了JLY3809機(jī)立窯(加料及窯罩部件)設(shè)計(jì)。JLY3809機(jī)立窯是目前新興的擴(kuò)的直徑窯,但在很多配套設(shè)備上還是沿用擴(kuò)徑前的技術(shù)設(shè)備,使得雖然進(jìn)行了改造,但是相關(guān)設(shè)備未能得到改進(jìn),未能體現(xiàn)出新窯的優(yōu)勢。本次設(shè)計(jì)了新型的加料裝置和窯罩。新型加料裝置對支承裝置和布料器做了改進(jìn),生產(chǎn)實(shí)踐表明支撐裝置經(jīng)過改造后,傳動平穩(wěn),且潤滑和檢修方便;改造后的布料器提升了高度,不易堵料,減輕看火工的勞動強(qiáng)度,布料器不易腐蝕,減少維修更換費(fèi)用;在升降裝置方面也做了一點(diǎn)小改動,增加了防扭器.改造后的窯罩便于運(yùn)輸,吊裝和易于銹蝕的下部可以單獨(dú)更換和拆卸。鑄鋼比普通的Q235鋼耐高溫,且鑄鋼內(nèi)含有一部分合金元素,又耐氧化不易變形等,故使用壽命一般比Q235鋼至少高2~3倍。設(shè)計(jì)中還涉及到沉降室和新型收塵器的選型,減少了資源的浪費(fèi),提高了水泥的生產(chǎn)效率,大大減少了機(jī)立窯對周圍環(huán)境的污染。

The charging and hooding parts designs of JLY3809 mechanical upright kiln
Abstract:This subject designs the charging and hooding parts of JLY3809 kiln. At present, JLY3809 mechanical upright kiln is a new emerging large diameter kiln. Because many corollary equipment have not been improved and still adopt conventional technology ,so the benefits with the new kiln can not been realized. In this subject we have designed the new charging device and hooding parts of kiln. The supporting and charge spreading have been improved ,too. The production practice indicates that the propping up equipment after transformation transmits steadily. Also the lubrication and the overhaul is convenient; after the transformation cotton material has promoted its altitude. The material cant be easily blocked, which reduces the labor intensity looks at the hot work, the cotton material is not easily corroded, reduced the repair and replacement; a point of small modification is also made in the elevating equipment aspect, adding in anti-turning equipment, after the transformation, the hooding parts of kiln is advantageous for the transportation, the hoisting and lower part which rusts is easily away possible alone to be replaced and disassembled. The cast steel is thermostabler than the ordinary Q235 steel, also the cast steel includes part of alloying elements, the oxidation and can not  be easily distorted and so on. The service life of it is generally 2~3 double higher than Q235 ,moreover in the design there also involves the settling pocket and the new dust catcher shaping, reduced the resources waste. Enhanced the cement production efficiency, reduced greatly the environment pollution made by mechanical upright kiln.
Key word:  mechanical; hooding parts of kiln; charging device; dust removal
