ZJ500型自洁式挤出造粒机设计(含CAD零件图装配图)(论文说明书14000字,CAD图8张)
摘 要
    本文内容主要是关于粉体技术、粉体造粒技术和ZJ500型自洁式挤出造粒机的设计计算说明书。
    本文大概分为两个部分，第一部分主要从粉体造粒的背景入手详细介绍了粉体技术、粉体造粒技术和氯化铵的性质，第二部分是本次毕业设计主题ZJ500型自洁式挤出造粒机的详细计算说明。
首先，本文介绍了粉体技术以及粉体技术未来的发展和它以后的前景。接着介绍了粉体的性质和性能。本文的ZJ500型自洁式挤出造粒机其实可以作为氯化铵造粒机，因此对氯化铵粉体的性能应做出详细介绍。本文分别从氯化铵在农业生产中的地位、氯化铵肥料的发展前景分别强调了氯化铵在现实生产中的重要性。本文又分别从氯化铵的反应式、用途、防护、储运等方面详细介绍了氯化铵的性质。
    双螺杆挤出机可以按不同角度分类，按螺杆啮合与否及其转向的异同进行的分类，以及相应的国际上著名的制造厂商输送机理不同，是双螺杆挤出机与单螺杆出之间主要区别之一。正如前文所述双螺杆挤出机因可按多种标准分类，从而种类繁多它们的工作特性差异很大拿正位移输送能力来说，并非所有的双螺杆挤出机都有正位移输送能力，即使有也还存在程度上的不同。因此，要详尽而无遗漏地分析双螺杆的工作特性是一件十分艰巨的工作。 [资料来源：https://www.doc163.com]
根据造粒机的结构可以确定造粒机设计的主体是造粒机轴的设计，参考机械设计所学习的知识设计轴应当优先根据轴上所要安装的零件进行轴的结构设计，再通过设计轴上所要安装零件的设计确定出轴上与零件配合处轴的尺寸。而轴上过度段的尺寸主要根据轴上零件的轴向定位来确定具体尺寸。而本次毕业设计轴上过渡段的尺寸设计主要以满足零件的轴向定位、轴承密封和整体结构的条件下进行的。尺寸确定后就要对轴上键进行校核，校核轴承以及校核轴的强度，确保满足轴的强度要求，轴承的寿命要求。轴设计结束后就是一些辅助设计包括上盖和底座的设计，其中重要的设计是料斗的设计，因为造粒
机效率不高的主要原因是粉体物料的失散，为了提高造粒机的效率，设计料斗的过程中应当充分考虑提高造粒机效率的作用。最后就是总装的设计，总装设计主要是把各零部件组装起来，但要满足传动要求。

 Abstract
     This article is mainly about powder technology, powder granulation technology and ZJ500-type self-cleaning type extrusion granulator design calculation manual.    This is probably divided into two parts, the first part of the background of the main starting from powder granulation powder technology introduced in detail, powder granulation technology and the nature of ammonium chloride, and the second part is this graduation design theme ZJ500 Self cleaning extrusion granulator detailed calculation instructions.First, the article describes the powder technology and powder technology development and its future prospects for the future. Then introduced the powder properties and performance. This article ZJ500 type self-cleaning type extrusion granulator granulator can actually be used as ammonium chloride, ammonium chloride powder so the performance should be made in detail. This paper from the chloride position in agricultural production, the development prospects of ammonium fertilizer ammonium chloride, respectively, emphasized the importance of the real production. This paper also took from the reaction of ammonium chloride, use, protection, transportation and other aspects described in detail the nature of ammonium chloride.    Twin-screw extruder at different angles can be classified according to whether or not their turn the screw engages the classification of similarities and differences, and the corresponding internationally renowned manufacturer of conveying mechanism is different, is a twin screw extruder and single screw out between One of the main differences. As mentioned earlier, a twin screw extruder according to a variety of standard classification due to their wide range of operating characteristics vary considerably positive displacement transmission capacity to take it, not all of the twin-screw extruder has a positive displacement transmission capacity, even if there are also the different levels. Therefore, to make a detailed analysis of twin screw without missing operating characteristics is a very difficult task.According to the structure can be determined granulator granulator granulator design is the main axis of the design, mechanical design reference design of the knowledge acquired should be given priority axes to be installed according to the shaft axis of the structural design of parts, and then through the design axis parts to be installed on the shaft and parts designed to determine a match at the shaft size. The size of the main section of the shaft over the shaft part according to [来源：http://www.doc163.com]
the axial positioning to determine the specific dimensions. And the second transition section of the shaft graduation designed primarily to meet the size of the axial positioning of parts, the overall structure of the bearing seal and the conditions. After determining the dimensions should be checked against the shaft keys, checking bearings and shaft strength check, ensure that it meets the shaft strength requirements, bearing life requirements. After the shaft design is that some aided design including cover and base design, the design is one of the important hopper design, granulating machine efficiency is not high because the main reason for the powder material is separated, in order to improve the efficiency of granulator, hopper design process should take full account of the role of improving the efficiency granulator. Finally is the assembly design, assembly designed primarily to assemble the various components, but to meet the transmission requirements.
