1.1帶式輸送機的的特點與應用
帶式輸送機自1795年被發(fā)明以來,經過兩個多世紀的發(fā)展,已被電力、冶金、煤炭、化工、礦山、港口等各行各業(yè)廣泛采用,特別是第三次工業(yè)革命帶來了新材料、新技術的采用使帶式輸送機的發(fā)展步入了一個新紀元。
當今,無論從輸送量、運距、經濟效益等方面來衡量,它已經可以同火車、汽車運輸相抗衡,成為三足鼎立局面,并成為各國爭先發(fā)展的行業(yè)。
1.1.1帶式輸送機的特點
(1)結構簡單。帶式輸送機的接由傳動滾筒、改向滾筒、托輥或無托輥部件、驅動裝置、輸送帶等幾大件組成,僅有十多種部件,能進行標準化生產,并可按需要進行組合裝配,結構十分簡單;
(2)輸送物料范圍廣泛。帶式輸送機的輸送帶具有耐磨、耐酸堿、耐油、阻燃等各種性能,并耐高、低溫,可按需要進行能夠制造,因而能輸送各種散料、塊料、化學品生熟料和混凝土;
(3)輸送量大。運量可從每小時幾公斤到幾千噸,而且是連續(xù)不間距輸送,這是火車、汽車運輸望塵莫及的;
(4)運距長。單機長度可達到十幾公里一條,在國外已經十分普及,中間無需任何轉載點。越野的帶式輸送機常使用中間摩擦驅動方式,使輸送機長度不受輸送帶強度的限制。
(5)對線路適應性強?,F(xiàn)代的帶式輸送機在越野鋪設時,已從槽形發(fā)展到圓形,它可在水平及垂直面上轉彎,打破了槽形輸送機不能打彎的限制,因而能依山靠水,沿地形而走,可節(jié)省大量修隧道,橋梁的基建投資。
(6)裝卸十分方便。帶式輸送機可根據工藝流程需要,可在任何點上進行裝、卸料。圓管式輸送機也是如此。也可以在回程段上裝、卸料,進行反向運輸;
(7)可靠性高。由于結構簡單,運動部件自重輕,只要輸送帶不被撕破,壽命可達十年之久,而金屬結構部件,只要防銹好,幾十年不壞;
(8)營運費低廉。帶式輸送機的磨損件僅為托輥和滾筒,輸送帶壽命長,自動化程度高,使用人員少,平均每公里不到一人,消耗的機油和電力也很少。
(9)能耗低,效率高。由于運動部件自重輕,無效運量少,在所有連續(xù)式和非連續(xù)式運輸中,帶式輸送機耗能最低,效率最高;
(10)維修費少。帶式輸送機運動部件僅是滾筒和托輥,輸送帶又十分耐磨。相比之下,火車、汽車磨損部件要多的多,且更換磨損件也較為頻繁;
綜上所述,帶式輸送機的優(yōu)越性已十分明顯,它是國民經濟中不可或缺的關鍵設備。加之國際互聯(lián)網絡化的實現(xiàn),又大大縮短了帶式輸送機的設計、開發(fā)、制造、銷售的周期,使它更加具有競爭力。
1.2帶式輸送機的現(xiàn)狀及發(fā)展
帶式輸送機是煤礦最理想的高效連續(xù)運輸設備,與其他運輸設備相比,具有輸送距離長、運量大、連續(xù)運輸等優(yōu)點,而且運行可靠、易于實現(xiàn)自動化和集中化控制,尤其對高產高效礦井,帶式輸送已成為煤炭開采機電一體化技術與裝備的關鍵設備,隨著我國高產高效礦井的出現(xiàn),原有的帶式輸送機無論是主參數還是運行性能都已不能滿足要求,必須向長距離、高帶速、大運量、大功率的大型化方向發(fā)展,并要改善和提高運行性能,確保安全可靠。
我國生產制造的帶式輸送機的品種,類型較多,在“八五”期間,通過國家一條龍“日產萬噸綜采設備”項目的實施,帶式輸送機的技術水平有了很大的提高,煤礦井下用大功率、長距離帶式輸送機的關鍵技術研究和新產品開發(fā)都取得了很大的進步。如大傾角長距離帶式輸送機成套設備,高產高效工作面順槽可伸縮帶式輸送機等均填補了國內空白,并對帶式輸送機的減低關鍵技術及其主要元部件進行了理論研究和產品開發(fā),研制成功了多種軟起動和制動裝置以及以PLC為核心的可編程電控裝置,驅動系統(tǒng)采用調速型液力耦合器和行星齒輪減速器。
煤礦帶式輸送機技術的發(fā)展趨勢:
設備大型化,提高運輸能力;為了適應高產高效集約化生產的需要,帶式輸送機的輸送能力需要加大,長距離、高帶速、大運量、大功率是今后發(fā)展的必然趨勢,也是高產高效礦井運輸技術的發(fā)展方向,在今后的10a內輸送量要提高到3000~4000t/h,帶速提高到4~6m/s,輸送長度對于可伸縮帶式輸送機要達到3000m。對于鋼繩芯強力帶式輸送機需加長至5000m以上,單機驅動功率要求達到1000~1500KW,輸送帶抗拉強度要達到6000N/ mm(鋼繩芯)和2500N/mm(鋼繩芯)。尤其是煤礦井下順槽可伸縮輸送技術的發(fā)展,隨著高產高效工作面的出現(xiàn)及煤炭科技的不斷發(fā)展,原有的可伸縮帶式輸送機,無論是主參數,還是運行性能都難以適應高產高效工作面的要求,煤礦現(xiàn)場急需主參數更大,技術更先進,性能更可靠的長距離、大運量、大功率順槽可伸縮帶式輸送機,以提高我國帶式輸送機技術的設計水平,填補國內空白,接近并趕上國際先進工業(yè)國的技術水平。其包含7個方面的關鍵技術: (1)帶式輸送機動態(tài)分析與監(jiān)控技術;(2)軟起動與功率平衡技術;(3)中間驅動技術;(4)自動張緊技術;(5)新型高壽命高速托輥技術;(6)快速自移機尾技術;(7)高速儲帶技術。
提高元部件性能和可靠性:設備開機率的高與低主要取決于元部件的性能和可靠性。除了進一步完善和提高現(xiàn)有元部件的性能和可靠性,還要不斷地開發(fā)研究新的技術和元部件,如高性能可控軟起動技術,動態(tài)分析與監(jiān)控技術,高效貯帶裝置、快速自移機尾、高速托輥等,使帶式輸送機的性能得到進一步提高。
擴大功能,一機多用化:拓展運人、運料或雙向運輸等功能,做到一機多用,使其發(fā)揮最大的經濟效益。開發(fā)特殊型帶式輸送機,如彎曲帶式輸送機、大傾角或垂直提升輸送機等。
大傾角帶式輸送機突破了丄運25°的極限,為煤礦開拓,開采及在斜井輸送設備的選型開辟了一條新途徑,也為當前斜井輸送系統(tǒng)改擴建提供了經濟高效的設備,對提高產量,降低成本具有重要意義。
水平帶式輸送機在我國礦山生產中有著廣闊的前景。我國傾斜煤層較多,16~25°傾斜煤層大量存在。帶式輸送機能成功地用于井下,既能減少巷道開拓量和設備投資又可加快工程進度具有較大的經濟效益。
