反应釜的常用构造

反应釜由釜体、釜盖、夹套、搅拌器、传动装置、轴封装置、支承等组成。搅拌形式一般有锚式、桨式、涡轮式、推进式或框式等，搅拌装置在高径比较大时，可用多层搅拌桨叶，也可根据用户的要求任意选配。并在釜壁外设置夹套，或在器内设置换热面，也可通过外循环进行换热。加热方式有电加热、热水加热、导热油循环加热、远红外加热反应釜、外(内)盘管加热等，冷却方式为夹套冷却和釜内盘管冷却，搅拌桨叶的形式等。支承座有支承式或耳式支座等。转速超过160转以上宜使用齿轮减速机。开孔数量、规格或其它要求可根据用户要求设计、制作。

The reaction kettle is composed of a kettle body, a kettle cover, a clamping sleeve, an agitator, a driving device, a shaft sealing device, and a support. Mixing in the form of anchor, paddle type, turbine type, propulsion or frame type, etc., mixing device in the high diameter, when you can use multi layer mixing paddle, can also be optional according to user requirements. A jacket is arranged outside the kettle wall, or a heat exchange surface is arranged in the device, and the heat exchange can also be carried out through an outer loop. The heating modes include electric heating, hot water heating, heat conducting oil circulating heating, far infrared heating reactor, outer (inner) coil heating, etc. cooling method is jacket cooling and kettle coil cooling, stirring paddle form and so on. The supporting seat has a support type or an ear type support. Gear reducer shall be used when the speed is over 160 rpm. The quantity, specifications or other requirements of the opening can be designed and manufactured according to user's requirements.

   1.通常在常压或低压条件下采用填料密封，一般使用压力小于2公斤。

 2.在一般中等压力或抽真空情况会采用机械密封，一般压力为负压或40公斤。

 3.在高压或介质挥发性高得情况下会采用磁力密封，一般反应釜压力超过14公斤以上。除了磁力密封均采用水降温外，其他密封形式在超过120度以上会增加冷却水套。

1. usually under normal or low pressure packing seal, the general use of less than 2 kg pressure.

2. in general medium pressure or vacuum conditions will use mechanical seal, the general pressure is negative pressure or 40 kg.

3., in high pressure or medium volatile high case will use magnetic seal, general reactor pressure more than 14 kilograms. In addition to the magnetic seals are using water cooling, other forms of sealing in more than 120 degrees will increase the cooling water jacket.
