【摘要】：中国饲料工业起步于20世纪70年代,已经历30多年的发展,逐步形成了饲料工业的主体地位,从1991年我国饲料总产量3570万吨到2011年的饲料总产量18063万吨,产值达到6348亿元,而饲料生产企业由1.5万多家缩减到1万家左右,并购甚至破产逐渐减少饲料企业,可见饲料行业竞争逐步日趋激烈,“大鱼吃小鱼,小鱼吃虾米”会在饲料行业出现,要想在社会发展中生存,就必须依靠科技创新,即巩固基础,发掘创新,本文本着对企业追求利润,结合饲料行业法律法规,适应市场经济发展而集成创新开发一套称重式液体添加设备,提高饲料料肉比的同时,饲料品质和经济效益也相应得到提升,为企业增强市场竞争力。本文根据饲料行业相关法规,查阅文献了解随着季节性变化,饲料含水率可控制在12.5%左右,而一般的饲料含水率在9.7%,所以水分有2%~3%的研究空间,加上水的种类与特性及饲料资源的利用率,水可分为游离水和结合水,结合生物技术、营养科学及饲料加工技术领域等知识研究了设计水添加设备工艺流程,集成开发了部件和单机设备之间的配合,使得整套设备符合企业生产要求,设计思路如下:1、调研市场与结合饲料企业需求,设计称重式水添加设备工艺流程;2、根据加水要求设计计算每批加水量的容积,满足最大自动加水称重的要求;3、分析流阻,计算管路和喷嘴所需压力对泵进行选型设计;4、设计管路自动泄压系统,保证管路受阻时管路安全和保护电机;本论文在设计完成后借助三维软件SolidWorks绘制设计安装,避免只有生产部件与单机才能发现设备的缺陷,提高设计效率,减少开发设计设备的时间,同时也节省单位成本,称重式水添加设备的应用得到广大饲料企业的好评,提高饲料行业获利率。
[Abstract]:China's feed industry began in the 1970s, has experienced more than 30 years of development, gradually formed the main position of the feed industry, from 1991 China's total feed output of 35.7 million tons to 2011 of the total feed output of 180.63 million tons, the output value of 634.8 billion yuan. While feed production enterprises have been reduced from more than 15000 to about 10 000, mergers and acquisitions and even bankruptcy have gradually reduced feed enterprises. It can be seen that competition in the feed industry is becoming increasingly fierce. "Big fish eating small fish and small fish eating shrimp rice" will appear in the feed industry. In order to survive in social development, we must rely on scientific and technological innovation, that is, to consolidate the foundation and explore innovation. In this paper, in the pursuit of profits for enterprises, combined with the laws and regulations of the feed industry, In order to adapt to the development of market economy and develop a set of weighing liquid adding equipment, the feed quality and economic benefit can be improved accordingly, so as to enhance the competitive power of the market for enterprises. According to the relevant laws and regulations of the feed industry, this paper looked up the literature and found that with the seasonal change, the feed moisture content could be controlled at 12.5%, while the general feed moisture content was 9.7%, so the water content had 2% and 3% research space. In addition to the types and characteristics of water and the utilization rate of feed resources, water can be divided into free water and combined water. In combination with the knowledge of biotechnology, nutrition science and feed processing technology, the technological process of designing water adding equipment is studied. The coordination between components and stand-alone equipment is integrated and developed to make the whole equipment meet the production requirements of the enterprise. The design ideas are as follows: (1) investigating the market and combining the demand of feed enterprises and designing the process flow of weighing water adding equipment; 2.According to the requirement of adding water, the volume of each batch of water is designed and calculated to meet the requirement of maximum automatic weighing of water. 3, the flow resistance is analyzed and the pressure required by pipes and nozzles is calculated to select the pump. 4, design the pipeline automatic pressure relief system to ensure the pipeline safety and protect the motor when the pipeline is blocked; After the completion of the design, the paper draws and installs the design with the help of three-dimensional software SolidWorks to avoid the defects of the equipment can be found only in the production parts and single machine, improve the design efficiency, reduce the development time of the design equipment, and at the same time save the unit cost. The application of weighing water addition equipment has been praised by feed enterprises, and the interest rate of feed industry has been raised.
