摘要:混涅机是一种用来搅拌工业原料的设备,又称混涅锅,它搅拌的物料具有一定的黏度,但此黏度在较高温度下有一定程度的降低,诸如沥青/石蜡/碳素等。混涅锅由一对互相配合和旋转的叶片(通常呈Z形)所产生强烈剪切作用而使半干状态的或橡胶状粘稠塑料材料能使物料迅速反应从而获得均匀的混合搅拌。混涅锅加热方式一分为:夹套加热、蒸汽加热和循环导热油加热,冷却方式一般为水冷却;采用液压翻缸及启盖。出料方式有液压出料、翻缸卸料、球阀出料,螺杆挤出等。目前,混涅锅主要用于碳素行业,是电解铝行业的配套设备,为电解铝生产提供电极。其所搅拌的物料根据性质又分为阴极糊和阳极糊两种,混涅容量1000L—6000L。混涅锅的主要工作部件是搅刀。本次设计的即3000升混涅锅搅刀轴系统设计,设计内容包括搅刀轴的强度、结构设计、使用寿命、等分析计算。24753 毕业论文关键词:搅刀;搅刀轴;使用寿命;强度
3000 litres of kneading machine's main boiler design
Abstract: Kneading machine is composed of a pair of complementary and rotating blades (usually a z-shaped) produces strong shearing. Kneading machine is a device used to mix industrial raw materials. It has a certain viscosity. However, viscosity will reduce to a certain extent when at high temperatures, such as pitch, paraffin wax, carbon and so on. Currently, kneading machine is mainly used for carbon trade, is the auxiliary equipment of electrolytic aluminum industry, providing electrodes for electrolytic aluminium production. Its mixture of material is pided into two kinds: positive electrode and negative electrode. Kneading capacity from 1000L to 6000L. A greater volume of kneading machine is under development. Kneading machine has a tendency to developing in larger volume Common method of discharging includes hydraulic ball valve, turn the cylinder dumping, screw extrusion and so on。Kneading machine is consist of the main boiler, rotor, knives, stripper agencies and so on The main part of the kneading machine are knives, and apart from the knives, boiler is the most important part. So in order to guarantee the life of the boiler, we put a layer of wear-resistant ability of materials---liner inside the boiler. This time, I will design the main boiler of 3000 liters kneading machine. Firstly, learn and master the work principle and structure of kneading machine according to review the literature online or in the library. Having a good use of knowledge learning from class ,include, mechanical design, mechanical theory, mechanical machining techniques and computer aided design is important Combing the theoretical knowledge learned in the past and improve the ability of theory with practice and integrated analysis Then, start to design 2~3 schemes about the main boiler and compare the advantages and disadvantages of each scheme, considering how to layout reasonable and how to choose material economical Lastly, I will do some analysis and calculation of main boiler strength, structural design, liner, main boiler, and the space from knife to kettle boiler liner.
