新型高粘度液体搅拌机设计

摘要

搅拌混合设备是一种流体机械产品，种类繁多、应用广泛，覆盖了化工、建筑、医药、食品、涂料等诸多行业,发挥着重要作用。搅拌混合设备是机械产品，但是在整个设计过程中会涉及机械、材料、工艺、控制等多方面知识。

本次设计的搅拌机是一款新型高粘度液体搅拌机，适用于多相高粘度液态物质的混合。在设计的过程中，既借鉴了已有经验，进行仿照设计，又在传统搅拌机械的基础上赋予了创新的元素。这款新型高粘度液体搅拌机的主要结构包括：动力装置、传动系统、搅拌系统和支撑部件。主要设计计算内容包括：搅拌器的选型、搅拌桶的设计、传动箱的设计、搅拌轴的设计及强度校核、搅拌功率与电动机额定功率的计算、联轴器的选用、轴承的选用及寿命计算等。

关键词：电动机传动箱轴承搅拌轴搅拌器

Abstract

Mixing equipment is a fluid mechanical products which has different types and is widely applied in chemical, construction, medicine, food, coating and many other industries. It plays an important role. Mixing equipment is the mechanical products, but in the whole course of the design, mechanical, material, process, control and so on various knowledge is involved.

What is designed this time is a new kind of high viscosity mixer, suitable for mixing the multiphase high viscosity liquid substances. In the process of design, I referred the previous experience, and added new element to the traditional mixing machinery. The main structure including: power device, transmission system, mixing system and support components. The main design and calculation include: the selection of the blender and coupling, the design of stirred vessel and the transmission case, the calculation of mixing power and the power rating of the motor, designing stirring shaft and check its strength, selecting bearings and calculating their lifetime, etc.

Keywords: electromotor transmission case bearings stirring shaft blender
