发布时间：2018-11-27 13:41
【摘要】：在清香型白酒的酿制过程中,酒曲非常重要;制曲机作为酒曲制作的关键装备,重要性不言而喻。机械化制曲具有很多人工制曲无法比拟的优点如劳动生产率高、制曲车间条件好和生产成本低等。但是机械制曲也存在设备维修率高、水资源浪费严重和液压回路的压力脉动过大等缺陷,这些缺陷阻碍了各大白酒企业自动化制曲机的应用。因此,本课题首先对汾酒集团制曲车间大曲的生产流程做了详细的研究,综合研究国内外曲胚块生产设备,参与设计一套稳定、高效、节水的清香型酒曲制曲机,来满足市场的紧迫需求。本文首先根据制曲机存在缺陷,对制曲机的结构进行设计,然后设计伺服液压回路,对蓄能器吸收脉动回路系统和伺服阀控液压缸系统建立了数学模型,并推出了清香型酒曲制曲机在正常工作时,蓄能器压力脉动传递函数和伺服阀控制液压缸的传递函数,应用MATLAB/Simulink软件绘制出在单位阶跃信号下的响应曲线,并对液压缸系统的模型进行了分析,系统无超调、稳定性好,但是响应速度达不到设计要求,故在系统中引入PID来对其改进,以保证设备的关键参数能达到生产工艺要求。为了防止制曲机的踩压系统和机架在激振频率下发生共振,本文通过ABAQUS软件确定踩压系统、机架的固有频率和模态柔度,确保制曲机在合理的频率范围内工作。为了检验建模和校正结果的正确性,在ADAMS和AMESim软件中搭建联合仿真平台,并进行仿真,仿真结果表明引入PID控制器和蓄能器对改善液压系统具有显著意义。为了进一步检验设计的设备在现场的稳定性,在现场搭建实验平台,进行了应用测试,通过Hydrotechnik Multi-System 5060液压万用表对液压系统的压力流量进行了检测;使用TYPE6230噪声检测仪对现场噪声进行检测;通过速度和位移传感器对液压缸的速度和位移进行了检测。根据检测结果与仿真结果的对比,可知清香型酒曲制曲机的设计合理,完全能满足现场工艺要求。
[Abstract]:Liquor is very important in the brewing process of Fen-Flavor Liquor, and its importance is self-evident as the key equipment of Liquor making. Mechanized koji making has many advantages, such as high labor productivity, good working conditions and low production cost. However, mechanical koji has some defects such as high maintenance rate of equipment, serious waste of water resources and excessive pressure pulsation of hydraulic circuit. These defects hinder the application of automatic koji making machines in major liquor enterprises. Therefore, this subject first made a detailed study on the production process of Daqu in Fenjiu Group koji making workshop, comprehensively studied the domestic and foreign koji production equipment, and participated in the design of a stable, efficient, water-saving wine koji making machine. To meet the urgent needs of the market. In this paper, the structure of the machine is designed according to the defects of the machine, and then the servo hydraulic circuit is designed. The mathematical model of the accumulator absorption pulsation loop system and the servo valve controlled hydraulic cylinder system is established. The pressure pulsation transfer function of accumulator and the transfer function of servo valve control hydraulic cylinder are deduced when the wine koji machine works normally, and the response curve under the unit step signal is drawn by using MATLAB/Simulink software, and the pressure pulsation transfer function of the accumulator and the transfer function of the servo valve control hydraulic cylinder are obtained. The model of the hydraulic cylinder system is analyzed. The system has no overshoot and good stability, but the response speed is not up to the design requirement. Therefore, PID is introduced into the system to improve the system to ensure that the key parameters of the equipment can meet the requirements of the production process. In order to prevent the pressure system and the frame of the starter from resonance under the exciting frequency, the paper determines the natural frequency and modal flexibility of the trampling system and the frame by ABAQUS software, so as to ensure that the machine works within a reasonable frequency range. In order to verify the correctness of the modeling and correction results a joint simulation platform was built in ADAMS and AMESim software. The simulation results show that the introduction of PID controller and accumulator is significant to improve the hydraulic system. In order to further test the stability of the designed equipment in the field, an experimental platform was set up, and the application test was carried out. The pressure and flow of the hydraulic system were tested by Hydrotechnik Multi-System 5060 hydraulic multimeter. The TYPE6230 noise detector is used to detect the field noise, and the speed and displacement of the hydraulic cylinder are measured by speed and displacement sensors. According to the comparison between the test results and the simulation results, it can be seen that the design of the wine-making machine is reasonable and can completely meet the requirements of the field technology.
