如何选择气力输送与机械输送，决定因素有哪些
我有更好的答案
机械输送投资高，气力输送相对便宜一点，看输送距离来吧，中远距离可以用方大JSB低压连续输送，长距离 可以选择方大QSB浓相气力输送，
采纳率：73%
中远距离输送宜采用低压气力输送，输送效率高，更环保

食品工程机械与设备课后题
第一章 总论
1、为什么要对食品加工设备进行分类？食品加工机械设备如何分类？
2、食品加工机械设备用材的基本要求是什么？从哪些方面考察食品机械设备的材料的性能？
3、分析讨论食品机械常用不锈钢材料的国内外标识型号及性能特点。
4、从食品卫生角度分析讨论食品加工机械设备的结构要求。
5、食品加工机械设备的选型原则是什么？
6、如何估算不同类型食品加工机械设备的生产能力？
一、判断题
1、我国尚未颁布食品机械设备分类标准。
2、食品加工机械设备多为成套设备。
3、食品加工机械设备应当全由不锈钢制造。
4、所有不锈钢材料在任何场合均不生锈。
5、各种不锈钢的基本成分是铁和铬。
6、一般不锈钢中的铬含量不超过28%。
7、食品工业不可采用非不锈钢材料制作的容器。
8、304不锈钢的镍含量为10%。
9、食品加工设备所采用的轴承都应为非润滑型。
10、具压力、高温内腔的设备应设置安全阀、泄压阀等超压泄放装置。
11、机械设备的安全操作参数包括额定压力、额定电压、最高加热温度等。
12、食品加工机械设备的噪声不应超过95dB（A）。
13、严禁在任何表面或夹层内采用玻璃纤维和矿渣棉作为绝热材料。
14、设备的产品接触表面应无凹坑、无疵点、无裂缝、无丝状条纹。
二、计算题
1、某罐头生产线杀菌工段有5台T7C5型杀菌锅用于209型罐的杀菌。如果杀菌公式为升温10min，保温40min和冷却20min。试求该生产线中封罐机的生产能力应为多少才能满足平衡生产要求。
2、某连续速冻机用于加工速冻饺子的生产能力为1t/h。试问，用于加工速冻包子的生产能力为多少？已知，饺子的冻结时间为20min，包子的冻结时间为30min，饺子的装载密度10kg/h，包子的装载密度15kg/h，速冻机输送链的有效载物宽度为0.7m。
3、通过参考有关资料，利用物料衡算关系建立螺旋带输送式加工处理设备（如速冻机）处理能力、物料滞留时间、物料装载密度、输送机回转半径、螺距、螺旋圈数及输送带速度之间的关系式。
4、通过参考有关资料，利用物料恒算关系建立悬挂链输送式加工处理设备（家禽加工线）处理能力、线载密度（单位链长上的载物质量，kg/m）、链速、物料滞留时间的关系式。

For this design, I first made a presentation for the belt conveyor and conveyor on development and is based on the design before a given performance parameters and operating conditions for automatic adjustment of the amount of feed belt conveying various component parts of the machine
finally, according to the results of each part of the automatic adjustment of the belt conveyor feed speed three-dimensional modeling, allowing us to be more intuitive to see the conveyor rather than the limitations of the various data. For conveyor We can divide it into three components are: gearing, hopper, automatic adjustment of the speed control device delivery. Currently, the general control of the drive motor to control the speed of the conveyor belt so as to control the speed of delivery of materials, for example the use of fupler and speed or the use of CST and other ways to speed the inevitable defects exist, so this graduation project out of the traditional way of the automatic control feed speed, using the source control conveyor belt conveyor speed. In the design by changing the hopper to control speed blanking speed their delivery of materials. Automatically adjusts feed speed can be seen as three parts are left so as to adjust the motor drive mechanism throughput size, right motor-driven belt conveyor, the intermediate bearing material hopper. In fact, the hopper is able to accommodate the production of the necessary materials and the materials can be transported by conveyor belt to the place we need. The role of the left part of the motor is to make the belt conveyor can automatically adjust according to the requirements under the hopper quantity of production. That is equivalent to an ordinary belt conveyor on the nature of the right part. With this feed speed control methods are mainly the following four advantages: First, the manufacturing cost is low, so tha the second is the control section on the left can be used as a gen the third is the transmission part can be seen on the right ordinary ordinary motor driven by belt conveyor to reduce the variety of
Fourth, because the control device and transmission equipment to work separately, so make maintenance easier. At present, there is a big gap in development with foreign belt conveyor, the conveyor so we still have a long way to go. Differences between China and abroad belt conveyor following major aspects: First, regardless of the country or abroad would not be conf, let me experience a return about the process of product design and development for the future that I have a more clear understanding of the way, as I will provide a reference for the selection of designs.Keywords: &Drive Ucovernor 1 绪论带式输送机是通过使用胶带、钢带、钢纤维带等传送构件来进行物料的传送以及扭矩的传递的一种应用很广泛的输送机械在同功能的众多的传送装置之间它是其中之一传输能力最大的可以进行连续执行输送任务的传输机械。带式输送机它的组成机构比较简单很容易理解、工作的时候整体的运行都是比较稳定、传输时侯安全可靠、一般只需要电动机带动所以消耗的电能相对比较低，同时电能作为一种清洁能源，所以自然而然对于工作环境污染比较较小、自动化程度较高、维修方便以及在生产过程中的生产成本相对较低，在不间断的上料的情况下它可以实现不间断的传输作用。带式输送机可以作为成件物件以及散状材料输送的一种很好的传动介质所以可以常常在电力、煤矿、交通等很多不同的领域见到带式输送机的身影。能够智能化的进行送料量调整的带式输送机，可以简单的理解成在普通带式输送机上加入自动控制送料量这一元素，从而使它在传送东西的时候可以按照生产需要来控制传送速度。自动调整送料量带式输送机因为通过皮带传送物料所以它提高了物料的拆卸速度从而提高了生产效率。1.3国内外关于带式输送机的现状及进展
1.3.1 国外带式输送机技术的现状 & & 因为它具有这么多优势，所以在国际有关它的技术发展情况可以说是日新月异，在它发展的方方面面均可以找到带式输送机的进步点，尤其在以下两点中最能表现：第一点是它的功用多元化以及适应性强，小到家用大到发电厂、船舶我们都能看到它的身影，而且在复杂的煤矿下面也能稳定的工作例如：高倾角带式输送机、管式带式输送机、空间转弯带式输送机等各种机型；另一点由于具有其他传输方式不可替代的优势，所以不管是在其自身技术层面还是它的设备样式均获得了得了极大的进展,特别是远距离输送、输送数量巨大、传送带运转速度快等一系列大型带式运输装置成为了研究者们首先考虑的方向。由于现代种种技术的问世所以很多高新的技术用到了带式输送机上使之操作朝着智能化发展，不仅使带式输送机以更加稳定的方式运行而且大大降低了工作者的劳动强度，在很大程度上提高了生产效率。因为带式输送机能够适应复杂的矿井环境，所以它在煤矿行业得到了广泛的使用，接下来将主要介绍它在煤矿下使用的特点。参考文献[1] 程居山. 矿山机械. 徐州: 中国矿业大学出版社, 2013；[2] 机械设计手册编写组. 机械设计手册. 化学工业出版社, 2014；[3] 方慎权. 煤矿机械. 徐州: 中国矿业学院出版社, 2010；[4] 北起所. &DTⅡ型带式输送机设计选用手册[M]. 冶金工业出版社.2012年.[5] 宋伟刚. 通用带式输送机设计[M]. 北京： 机械工业出版社，2006;[6] 王学炳，韩东劲. 带式输送机可控软起动装置的研究[J]. 煤矿运输，2015（45）：14-22;[7] 宋伟刚，张尊敬，王鹰. 带式输送机的研究进展[J]. 起重运输机械，2014，（2）：1-4；[8] 毛君,师建国，张东升.带式输送机启动特性和可控技术研究[J].矿山机械，）：19-22；[9] 吴琼, 钱余龙. 张紧装置在带式输送机中的应用[J]. 中国新技术新产品, 2015, (第5期);[10] 李利, 王瑞, 党栋. 带式输送机的技术现状及发展趋势[J]. 橡胶工业, 2015, (第2期);[11] 张雁峰. 带式输送机节能降耗控制方法研究[J]. 黑龙江科技信息, 2015, &(第5期);[12] 闫巧枝, 熊旭平, 马磊. 某矿大倾角带式输送机的技术改进[J]. 煤矿机械, 2015, (第1期);[13] 葛凯. 小纪汗煤矿带式输送机控制系统[J]. 科技与创新, 2015, &(第1期);[14] 秦勇. 带式输送机的驱动系统浅析[J]. 价值工程, &2014, (第25期);[15] 赫桂平. 带式输送机的安装、 使用与维护[J]. 中国科技投资, 2014, (第1期);[16] 王进辉. 带式输送机滚筒改进设计[J]. 机械工程师, 2014, (第11期);[17] 吉雪花. 小功率直流伺服电机调速系统的设计[D]. 保定: 河北农业大学硕士学位论文，；
