常见的气力输送设备如何安装？

How to install common pneumatic conveying equipment?

1、一般情况下，料封泵装在料仓库底比较合适，落料顺畅。如果放不在库底，置于旁边亦可。但落料管斜角≥45°。如果装在电除尘落灰斗下部，可以一斗一泵，亦可两斗两斜管一泵;特殊情况亦可四斗四斜管插入一台料封泵中，但所有落灰斜管的斜度均应≥45°。

1. Generally, it is appropriate to install the material seal pump at the bottom of the material warehouse, and the material can be discharged smoothly. If it is not placed at the bottom of the warehouse, it can also be placed next to it. However, the inclined angle of the blanking pipe is ≥ 45 °. If it is installed at the lower part of the electrostatic precipitator ash hopper, it can be one bucket with one pump, or two buckets with two inclined pipes with one pump; Under special circumstances, four buckets and four inclined pipes can also be inserted into a material sealing pump, but the inclination of all ash falling inclined pipes shall be ≥ 45 °.

2、料封泵一般置于坚硬的水平地面上即可，无需打基础安装地脚螺栓，当风管,出料管连接好以后，即可投运。但要求进风管与泵管连接时应安装一个挠性节头。

2. Generally, the material seal pump can be placed on a hard horizontal ground without foundation and foundation bolts. It can be put into operation after the air duct and discharge pipe are connected. However, a flexible joint shall be installed when the air inlet pipe is connected with the pump pipe.

3、料封泵的总高(包括料封泵灰斗)一般为3.5-4.5m，根据现场实际情况亦可适当变动。

3. The total height of the material seal pump (including the ash hopper of the material seal pump) is generally 3.5-4.5m, which can be appropriately changed according to the actual situation on site.

4、料封泵放置出口方向，可根据现场情况而定，一般超向灰库所在位置的方向为宜，或根据管路的走向而定。

4. The outlet direction of the material seal pump can be determined according to the site conditions. Generally, it is appropriate to go beyond the direction where the ash silo is located, or according to the direction of the pipeline.

5、本装置要求库顶收尘器的气体散放量应大于料封泵送料带风总量。勿使库内出现正压情况，以免影响输灰系统工作。

5. The device requires that the gas emission amount of the dust collector on the top of the silo should be greater than the total amount of air carried by the material seal pump. Do not cause positive pressure in the silo, so as not to affect the operation of the ash conveying system.

6、要求气源、料封泵、输灰管全系统密封良好，漏风率小于 0.2%。

6. The air source, material seal pump and ash conveying pipe shall be well sealed, and the air leakage rate shall be less than 0.2%.

气力输送

Pneumatic conveying

气动式真空上料机即是利用压缩空气通过真空发生器产生高真空实现对物料的输送，不需要机械式真空泵，具有结构简单、体积小、免维修、噪音低、控制方便、消除物料静电和符合GMP要求等优点。真空发生器产生的高真空，使被输送的物料杜绝了分层现象，保证了混合物料成分的均一性，是压片机、胶囊填充机、干法制粒机、包装机、粉碎机、振动筛等机械自动上料的选设备。 当压缩空气供给真空发生器时，真空发生器就产生负压形成真空气流，物料被吸入吸料咀，形成物气流，经过吸料管到达上料机的料仓内。过滤器把物料与空气完全分离，当物料装满料仓时，控制器会自动切断气源，真空发生器停止工作，同时料仓门自动开启，物料落到设备的料斗中。与此同时，压缩空气通过脉冲反吹阀自动清洗过滤器。等到时间到或料位传感器发出上料信号时，自动启动上料机。

The pneumatic vacuum feeder uses compressed air to generate high vacuum through the vacuum generator to realize the delivery of materials. It does not need a mechanical vacuum pump. It has the advantages of simple structure, small volume, maintenance free, low noise, convenient control, elimination of material static electricity and compliance with GMP requirements. The high vacuum generated by the vacuum generator eliminates the stratification of the conveyed materials and ensures the homogeneity of the components of the mixed materials. It is a sorting equipment for automatic mechanical feeding, such as tablet press, capsule filling machine, dry granulation machine, packaging machine, crusher, vibrating screen, etc. When the compressed air is supplied to the vacuum generator, the vacuum generator will generate negative pressure to form a vacuum air flow. The materials are sucked into the suction nozzle to form an air flow, which will reach the silo of the feeding machine through the suction pipe. The filter completely separates the material from the air. When the material is full of the silo, the controller will automatically cut off the air source, the vacuum generator will stop working, the silo door will automatically open, and the material will fall into the hopper of the equipment. At the same time, the compressed air automatically cleans the filter through the pulse back blowing valve. When the time is up or the material level sensor sends the feeding signal, the feeding machine will be started automatically.
