【摘要】：帶式輸送機(jī)作為一種重要的散裝物料輸送設(shè)備,生產(chǎn)率高,優(yōu)勢(shì)明顯,在各個(gè)行業(yè)都得到了廣泛的應(yīng)用,尤其是通用帶式輸送機(jī)的運(yùn)用更為常見。但是在實(shí)踐中,我們發(fā)現(xiàn)通用帶式輸送機(jī)存在著零部件數(shù)量多、維護(hù)維修費(fèi)用高、起動(dòng)困難、噪聲大、輸送帶易跑偏且易摩擦起熱等問題,嚴(yán)重制約著輸送機(jī)的發(fā)展空間。因此設(shè)計(jì)出能解決或避免此類問題的新型帶式輸送機(jī),將會(huì)成為輸送設(shè)備研究的新前沿。 本文在研究適應(yīng)環(huán)境的特種帶式輸送機(jī)同時(shí),尋求建立在物理學(xué)基礎(chǔ)上的運(yùn)輸手段新途徑,試圖將磁力機(jī)械技術(shù)引用到帶式輸送機(jī)上,利用磁斥力的特點(diǎn)將膠帶與托輥分離,去除托輥,采用非接觸式磁懸浮支承,徹底改變傳統(tǒng)輸送機(jī)結(jié)構(gòu)所帶來的發(fā)展缺陷。 為使研究更為方便,對(duì)磁墊式帶式輸送機(jī)進(jìn)行了力學(xué)模型的簡(jiǎn)化,在此基礎(chǔ)上,分別研究了磁墊式帶式輸送機(jī)的兩種模式,一是利用永磁懸浮支撐模式,二是利用通電線圈電磁懸浮支撐模式。重點(diǎn)研究了永磁支撐模式,分析討論了永磁體磁懸浮的工作機(jī)理,對(duì)永磁產(chǎn)生磁力的影響因素如間隙距離、磁體高度、磁性材料等分別進(jìn)行了有限元仿真分析,繪制了相應(yīng)的磁場(chǎng)強(qiáng)度圖和相關(guān)參數(shù)影響曲線圖,探索了永磁體支撐的優(yōu)化變量,同時(shí)對(duì)其平衡穩(wěn)定性作出了分析。 本文還針對(duì)磁墊式帶式輸送機(jī)的牽引力計(jì)算進(jìn)行了分析,對(duì)其部件機(jī)構(gòu)也進(jìn)行相關(guān)的設(shè)計(jì)和討論,尤其是磁性輸送帶、防磁托輥、防磁滾筒、磁鐵質(zhì)的去除裝置等部件給出較為詳細(xì)的設(shè)計(jì)及設(shè)計(jì)思路。最后舉例說明磁墊式帶式輸送機(jī)的經(jīng)濟(jì)性。另外,筆者在文中對(duì)其他磁墊式構(gòu)想設(shè)計(jì)和思路也進(jìn)行了簡(jiǎn)單說明。
[Abstract]:As an important equipment for conveying bulk materials, belt conveyor has high productivity and obvious advantages. It has been widely used in various industries, especially in the use of universal belt conveyor. However, in practice, we find that the general belt conveyor has many problems, such as large number of parts and components, high maintenance cost, difficult starting, high noise, easy deviation of conveyor belt and friction and heat, etc., which seriously restricts the development space of conveyor. Therefore, the design of a new belt conveyor which can solve or avoid such problems will become a new frontier in the research of transportation equipment. In this paper, at the same time of studying the special belt conveyor which adapts to the environment, we seek a new way of transportation based on physics. We try to apply the magnetic mechanical technology to the belt conveyor and separate the belt from the roller by using the characteristic of magnetic repulsion force. Remove roller, adopt non-contact magnetic suspension support, completely change the traditional conveyor structure caused by the development defects. In order to make the research more convenient, the mechanical model of magnetic cushion belt conveyor is simplified. On this basis, two modes of magnetic cushion belt conveyor are studied, one is to use permanent magnetic suspension support mode. The second is the use of electrified coil electromaglev support mode. The working mechanism of permanent magnet magnetic levitation is analyzed and discussed. The influence factors such as gap distance, magnet height and magnetic material are simulated by finite element method. The corresponding magnetic field intensity diagram and the influence curve of relative parameters are plotted, and the optimization variables of permanent magnet bracing are explored, and the equilibrium stability of the permanent magnet is analyzed. In this paper, the traction calculation of magnetic cushion belt conveyor is analyzed, and the relevant design and discussion of its component mechanism are also carried out, especially the magnetic conveyor belt, anti-magnetic roller, etc. The design and design idea of magnet removal device and other parts are given in detail. Finally, an example is given to illustrate the economy of magnetic cushion belt conveyor. In addition, the author also gives a brief explanation of other magnetic cushion design and ideas in this paper.
