I 摘 要
瓦斯是煤矿生产中的很难管理控制的一种危险隐患，同时也是一种能源及化工资源。为了做好瓦斯抽放，搞好瓦斯的防治工作，提高瓦斯的资源利用率。所以，必须再瓦斯抽放过程中确保无瓦斯泄漏，务必把抽放钻孔封堵完备。这就需要使用封填材料，而此材料是一种混合浆液，需要用搅拌设备将其搅拌均匀。而搅拌设备使用历史悠久，应用范围广。在化学工业、石油工业、建筑行业等等传统工业中均有广泛的使用。搅拌操作看来似乎间单，单实际上，它所涉及的因素却极为复杂。本文介绍了小型搅拌器设计的基本思路和基本理论，分析了搅拌器的基本结构及其相关内容，阐述了搅拌器的运动及其动力装置。通过对搅拌器的基本设备的描述和对其基本工作原理、作用和功能等相关文献的参与，从而对小型搅拌器的设计加以综述。

II Abstract
Gas drill holes sealing system mixing part of the design and
analysis
The gas is difficult to manage in the coal mine production control
of a dangerous hidden, And also a kind of energy and chemical resources.
In order to carry gas drainage , improve the prevention and control of
the gas , improve the utilization of gas resources. And also a kind of
energy and chemical resources. In order to carry gas drainage , improve
the prevention and control of the gas , improve the utilization of gas
resources. The operation of mix round looks as if simpleness, but actually,
the ingredient it involved are plaguy of small pulsator design, and
analyzed the basic configuration of pulsator and interfix content and
analyzed the athletics and motivity equipment of pulsator. Overpass
describe the basic fixture of pulastor and consult its basic employment
principle. Function and operation, thereby summarize the design of small
pulsator.
