【摘要】：隨著瓦楞紙板生產設備的快速發(fā)展,在綠色經濟的發(fā)展趨勢下,作為瓦楞紙板生產線核心機器的瓦楞機只有向著高效節(jié)能的方向發(fā)展,才能夠獲得更大的發(fā)展空間。因此,自主研發(fā)出高速高檔的瓦楞機對于我國瓦楞紙板行業(yè)具有重大意義。本文針對瓦楞機對瓦楞紙板生產技術進行研究,根據企業(yè)自主研發(fā)的高速瓦楞機在實際生產時出現(xiàn)的問題,對高速瓦楞機的相關設計結構進行分析,結合瓦楞機實際生產時的相關參數和數據,采用有限元仿真和數學建模的方法對瓦楞機中出現(xiàn)的生產問題進行分析和計算,找到問題根源。最后通過改進瓦楞機的相關設計解決瓦楞機在生產過程中出現(xiàn)的問題并對瓦楞機進行節(jié)能改造,提高其生產效率,節(jié)約能源。本文通過FLUENT仿真平臺對導紙壓力腔的實際工況進行模擬分析,得到了在工作過程中導紙壓力腔內的速度和壓力分布情況,并結合相關工藝要求對導紙壓力腔進行了結構優(yōu)化,最終得到了滿足高速瓦楞機工藝要求的導紙壓力腔結構。建立了高速瓦楞機蒸汽系統(tǒng)進行數學建模,得到蒸汽汽路流量和壓降模型,通過對傳統(tǒng)和舊式改造瓦楞機中的故障進行問題分析,并結合實際數據對問題進行計算驗證,找到了故障原因所在,最后通過合理布置系統(tǒng)汽路解決傳統(tǒng)和舊式方案中疏水不暢問題,優(yōu)化高速瓦楞機蒸汽汽路并且提高蒸汽利效率。全文通過對瓦楞機進行分析和計算,提出相關優(yōu)化建議及改進方案,為研發(fā)高效節(jié)能的單面瓦楞機提供理論依據和參考數據。
[Abstract]:With the rapid development of corrugated paperboard production equipment, under the development trend of green economy, corrugated machine, as the core machine of corrugated paperboard production line, can only develop in the direction of high efficiency and energy saving. Therefore, the independent development of high-speed and high-grade corrugated machine for our corrugated board industry has great significance. In this paper, the corrugated board production technology is studied for corrugated machine, and the related design structure of the high-speed corrugated machine is analyzed according to the problems in the actual production of the high-speed corrugated machine developed independently by the enterprise. Combined with the relevant parameters and data of corrugated machine in actual production, finite element simulation and mathematical modeling are used to analyze and calculate the production problems in corrugated machine, and to find out the root of the problem. Finally, the problems of corrugated machine in the production process are solved by improving the corrugated machine design, and the corrugated machine is reformed to improve the production efficiency and save energy. In this paper, the actual working conditions of the guide paper pressure chamber are simulated and analyzed by FLUENT simulation platform, the velocity and pressure distribution in the guide paper pressure chamber are obtained, and the structure of the guide paper pressure chamber is optimized according to the relevant process requirements. Finally, the structure of guide paper pressure chamber is obtained to meet the requirements of high speed corrugated machine. The mathematical model of steam system of high-speed corrugated machine is established, and the steam flow and pressure drop model are obtained. The problems of traditional and old corrugated machine are analyzed, and the problems are calculated and verified by combining with actual data. Finally, the problem of hydrophobic problem in traditional and old schemes is solved by reasonably arranging the steam path of the system, the steam path of high speed corrugated machine is optimized and the steam profit efficiency is improved. Based on the analysis and calculation of corrugated machine, the paper puts forward some suggestions for optimization and improvement, which provides theoretical basis and reference data for the research and development of high efficiency and energy saving single-sided corrugated machine.
