【摘要】：橡膠瀝青技術(shù)是目前世界范圍內(nèi)應(yīng)用前景十分廣闊的一門道路工程材料技術(shù),其之所以受到人們的青睞首先是因?yàn)橥ㄟ^(guò)這項(xiàng)技術(shù)獲得的改性瀝青具有十分優(yōu)良的特性,滿足了人們對(duì)普通瀝青提出的改性要求,其次是生產(chǎn)橡膠瀝青所使用的膠粉來(lái)源于廢舊輪胎等,為這類廢舊橡膠制品的廢物再利用提供了一種有效解決途徑,一舉兩得。任何的工程技術(shù)都離不開工程裝備作為基礎(chǔ)與支持,橡膠瀝青也不例外,目前對(duì)于橡膠瀝青制備設(shè)備的研究與開發(fā)多集中在大型的生產(chǎn)設(shè)備,而小型化的試驗(yàn)用設(shè)備鮮有人涉足,但是對(duì)于改性瀝青的研發(fā)來(lái)說(shuō),最重要的就是試驗(yàn)環(huán)節(jié),如果此時(shí)沒(méi)有專業(yè)的試驗(yàn)用制備設(shè)備提供保障,那么試驗(yàn)效果將會(huì)是事倍功半。所以,當(dāng)前十分有必要對(duì)這類小型化的試驗(yàn)用制備設(shè)備展開研究。本文在實(shí)地調(diào)研與閱讀文獻(xiàn)的基礎(chǔ)上,總結(jié)當(dāng)前試驗(yàn)用制備設(shè)備的不足體現(xiàn)在三方面,即:加熱、攪拌、通風(fēng)凈化。本文將以上述三個(gè)方面為研究方向,采用理論分析、計(jì)算機(jī)模擬與試驗(yàn)驗(yàn)證相結(jié)合的方式展開研究。加熱方面,通過(guò)對(duì)各種常用加熱方式的特點(diǎn)以及局限性進(jìn)行分析后,采用電磁加熱作為瀝青的加熱方式,并利用ANSYS進(jìn)行仿真,得到了不同參數(shù)下容器壁上的磁場(chǎng)、渦流及溫度分布云圖,確定了適宜的激勵(lì)電流與激勵(lì)頻率范圍。攪拌方面,通過(guò)查閱文獻(xiàn)資料,選擇了六葉盤式渦輪攪拌器,并對(duì)擋板、攪拌器尺寸、攪拌位置、粘度、膠粉粒徑、攪拌轉(zhuǎn)速對(duì)膠粉分布的影響及葉片在預(yù)應(yīng)力下的模態(tài)響應(yīng)做了模擬研究。通風(fēng)凈化方面,通過(guò)對(duì)通風(fēng)的控制方式、氣流組織方式的認(rèn)真研究以及對(duì)各種空氣凈化方法的特性的對(duì)比優(yōu)選,結(jié)合實(shí)際應(yīng)用場(chǎng)合,選擇全面通風(fēng)并采用下送上排的氣流組織方式,凈化方法采用以活性炭為吸附劑的吸附法,然后對(duì)容器的三種常用位置下的通風(fēng)過(guò)程進(jìn)行了模擬。最后,針對(duì)三個(gè)方面分別設(shè)計(jì)了一個(gè)驗(yàn)證性的試驗(yàn),通過(guò)試驗(yàn)驗(yàn)證了設(shè)計(jì)的有效性,并借助于試驗(yàn)現(xiàn)象及得出的試驗(yàn)數(shù)據(jù)對(duì)其性能有了更實(shí)際、更直觀的了解。
[Abstract]:Rubber asphalt technology is a widely used road engineering material technology in the world at present. The reason why it is favored by people is that the modified asphalt obtained by this technology has very good characteristics. The rubber powder used in the production of rubber asphalt comes from waste tires, which provides an effective way to reuse the waste of this kind of waste rubber products and can kill two birds with one stone. Any engineering technology can not be separated from engineering equipment as the foundation and support, and rubber asphalt is no exception. At present, the research and development of rubber asphalt preparation equipment is mostly focused on large-scale production equipment. But for the research and development of modified asphalt, the most important is the test link, if there is no professional experimental equipment to provide protection, then the test effect will be half the effort. Therefore, it is necessary to study this miniaturized experimental preparation equipment. On the basis of field investigation and reading literature, this paper summarizes the shortcomings of the present experimental preparation equipment in three aspects: heating, stirring, ventilation and purification. In this paper, the above three aspects will be taken as the research direction, and the research will be carried out by means of theoretical analysis, computer simulation and experimental verification. In the heating aspect, after analyzing the characteristics and limitations of various common heating methods, electromagnetic heating is used as the heating method of asphalt, and the magnetic field on the wall of the vessel under different parameters is obtained by ANSYS simulation. The suitable excitation current and frequency range are determined by cloud diagram of eddy current and temperature distribution. In the aspect of stirring, by consulting the literature, the six-leaf disk turbine agitator is selected, and the baffle, agitator size, stirring position, viscosity, rubber particle size, The influence of stirring speed on the distribution of rubber powder and the modal response of blade under prestress were simulated. In the area of ventilation purification, through the careful study of the control mode of ventilation, the way of airflow organization and the comparison and optimization of the characteristics of various air purification methods, combined with the practical application situation, In this paper, the overall ventilation was selected and the air flow organization was adopted, and the adsorption method with activated carbon as the adsorbent was used to purify the vessel. Then the ventilation process in three common locations of the container was simulated. Finally, a confirmatory test is designed for the three aspects, and the validity of the design is verified by the experiment, and its performance is more practical and intuitionistic with the help of the experimental phenomena and the experimental data obtained.
