摘 要
本选题“水平桨叶式混合机结构设计”来源于工业生产和制造领域的实际需求。随着现代工业的发展，混合设备在化工、制药、食品等多个行业中扮演着至关重要的角色。特别是在需要高效、均匀混合的场合，对混合机的性能和设计要求越来越高。因此，研究和开发新型、高效、可靠的混合机结构成为了当前工程领域的一个重要课题。水平桨叶式混合机作为一种常见的混合设备，具有广泛的应用前景。然而，现有的混合机在设计上往往存在一些不足，如传动效率低、结构复杂、维护困难等问题。本选题结合了工程实际和技术发展趋势，通过对混合机的工作原理、传动方案、结构特点等方面进行深入研究和分析，提出了一种新型的水平桨叶式混合机结构设计方案。
本文旨在设计一种水平桨叶式混合机的结构，以满足特定的技术要求。该混合机具有直径36厘米的混合腔，主电机功率达到30千瓦，容量范围为15立方米/小时，顶尖速度达到20米/秒。设计中，电动机通过硬齿面斜齿减速器、联轴器与旋转轴相连，形成可靠的传动系统。原料通过锥形进料口投入，混合操作则由混合腔内的单轴单层桨叶结构转子完成。混合完成后，出料口闸门打开，实现快速卸料。该设计方案具有传动可靠、效率高、结构紧凑、使用成本低以及维修方便等优点，适用于多种混合需求，具有较高的实用价值和应用前景。

Abstract
This topic selection "structural design of horizontal blade mixer" comes from the actual demand of industrial production and manufacturing field. With the development of modern industry, hybrid equipment plays a vital role in chemical, pharmaceutical, food and other industries. Especially in the need for efficient and uniform mixing occasions, the performance and design of the mixer are more and more demanding. Therefore, the research and development of new, efficient and reliable hybrid machine structure has become an important topic in the current engineering field. As a common hybrid equipment, the horizontal paddle mixer machine has a wide application prospect. However, the existing hybrid machine often has some deficiencies in the design, such as low transmission efficiency, complex structure, difficult maintenance and other problems. This topic combines the engineering practice and technical development trend, through the working principle, transmission scheme, structural characteristics and other aspects of in-depth research and analysis, put forward a new type of horizontal blade hybrid machine structure design scheme.
This paper aims to design the structure of a horizontal blade mixer to meet the specific technical requirements. The mixer has a mixing cavity with a diameter of 36 cm, a main motor power of 30 kilowatts, a capacity range of 15 m 3 /h, and a top speed of 20 m /s. In the design, the motor is connected with the rotating shaft through the hard tooth reducer and the coupling to form a reliable transmission system. The raw material is input through the conical feed inlet, and the mixing operation is completed by the uniaxial single-layer blade structure rotor in the mixing cavity. After mixing, the discharge gate is opened to achieve rapid unloading. The design scheme has the advantages of reliable transmission, high efficiency, compact structure, low use cost and convenient maintenance, which is suitable for a variety of mixed requirements, and has high practical value and application prospect.
Key words: horizontal blade mixer; structure design; blade structure; transmission scheme and unloading system
