The design of mixer, mixer and mixer includes process design and mechanical design. The process design puts forward the original conditions of mechanical design, i.e. processing quantity, operation mode, large working pressure (or vacuum degree), high working temperature (or low working temperature), physical properties and corrosion of stirred materials, as well as the type and heat transfer area of heat transfer surface, agitator type, mixing speed and power, etc. The mechanical design shall reasonably select the mixing vessel, transmission device, shaft seal and internal components, and calculate the strength (or stiffness) and structural design.

化学 搅拌 减速器 的具体 选型 步骤 分析 ：对搅拌机 、搅拌机 、搅拌机 的具体任务 、选型 、用途 。 设计 的全部 依据 来源于 搅拌 的任务 和目的 。 其基本 内容 应包括 ：明确 被搅拌 物料 体系 ；搅拌 操作 所达到 的目的 ；被搅拌 物料 的处理量 （间歇 操作 按伊个周期 的批量 ，连续 操作 按时 班或年处理量 ）；明确 有无 化学反应 ，有无 热量传递等，考虑 反应 体系 对搅拌 效果 的要求 。 搅拌机 、搅拌器 、搅拌机 选型 之了解 物料 性质 。

Analysis of specific selection steps of chemical mixing reducer: specific tasks, selection and use of mixer, mixer and mixer. The design is based on the task and purpose of mixing. The basic contents shall include: clarifying the mixed material system; The purpose of mixing operation; The processing capacity of the mixed materials (batch operation according to one cycle, continuous operation, on-time shift or annual processing capacity); Determine whether there is chemical reaction and heat transfer, and consider the requirements of the reaction system for mixing effect. Understand the material properties of mixer, mixer and mixer selection.

材料 系统 特性 是搅拌机 设计 计算 的基础 。 物系性质 包括 物料 处理量 ，物料 的停留时间 ，物料 的黏度 ，体系 在搅拌 或反应 过程 中达到 的大黏度 ，物料 的表面张力 ，粒状 物料 在悬浮 介质 中的沉降速度 ，固体 粒子 的含量 和通气 量等。 搅拌机 、搅拌器 、搅拌机 选型 之搅拌器 选型 。 搅拌器 的结构 型式 和混合 特性 很大 程度 上决定 了体系 的混合 效果 。 而且 搅拌器 的型号 是根据 搅拌 物质 来选择 的。

Material system characteristics are the basis of mixer design and calculation. The properties of the material system include the material handling capacity, the residence time of the material, the viscosity of the material, the high viscosity of the system in the process of stirring or reaction, the surface tension of the material, the settling speed of granular material in the suspension medium, the content of solid particles and ventilation, etc. Mixer, mixer and mixer selection. The mixing effect of the system is largely determined by the structure and mixing characteristics of the agitator. Moreover, the model of the agitator is selected according to the mixing material.

搅拌机 、搅拌器 、搅拌机 选型 之搅拌 特性 计算 搅拌 特性 包括 搅拌 功率 ，循环 能力 ，切应变速率 及分布 等，根据 搅拌 任务 及目的 确定 关键 搅拌 特性 。 搅拌 功率计算 又分两个 步骤 ，第伊步确定 搅拌 功率 ；第二步 考虑 轴封 和传动装置 中的功率 耗，确定 适当 的电动机 额定功率 ，进而 选用 相应 的电动机 。 混合 、混合 、混合 等选型 的热传导 设计 为在搅拌 工作中 有热量传递时，应进行 传热 计算 。 其主要 目的 是核算 搅拌机 提供 的换热 面积 是否 满意 是传热 的要求 。 在满足 工艺 要求 的前提 下，估计 搅拌机 、搅拌机 、搅拌机 的选择 成本低 是评价 搅拌机 性能 、验证 设计 是否 合理 的重要 指标 之一 。

Calculation of mixing characteristics of mixer, mixer and mixer selection, including mixing power, circulation capacity, shear strain rate and distribution, etc., and determine the key mixing characteristics according to the mixing task and purpose. The calculation of mixing power is divided into two steps. The first step is to determine the mixing power; The second step is to consider the power consumption in the shaft seal and transmission device, determine the appropriate rated power of the motor, and then select the corresponding motor. The heat conduction design of mixing, mixing and mixing is that when there is heat transfer during mixing, heat transfer calculation shall be carried out. Its main purpose is to check whether the heat exchange area provided by the mixer is satisfactory, which is the requirement of heat transfer. On the premise of meeting the process requirements, estimating the low selection cost of mixer, mixer and mixer is one of the important indexes to evaluate the performance of mixer and verify whether the design is reasonable.
