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。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。混涅机的主要工作部件是搅刀,除搅刀之外最重要的部件就是锅体,搅刀的耐磨寿命远远大于锅体,这样,为了保证锅体的使用寿命,在锅体内面加上一层耐磨能力强的材料———衬板。本次设计的即3000升混涅锅主锅体设计,主锅体为混涅锅工作时原料搅拌,加热用。设计内容包括主锅体的强度、结构设计、衬板、主锅体使用寿命、搅刀和锅体衬板间距等分析计算。22328 毕业论文关键词: 主锅体;衬板;搅刀;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 1000Lto 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.
