气力输送系统可以按客户提供的材料特性(尺寸、重量等)的传输距离,攀爬高度,现场条件,生产能力,传递模式(间歇或连续)等进行设计,选择合适的设备,其工作原理是利用空气动能暂停国有粮食材料,插头形状或沙丘,气流沿管道,设备的空运散装方式按给定的压力分为三种:吸送式、压送式和混合式。

The pneumatic conveying system can be designed according to the material characteristics (size, weight, etc.), transmission distance, climbing height, site conditions, production capacity, transmission mode (intermittent or continuous), etc. provided by customers. The working principle of the pneumatic conveying system is to use the air kinetic energy to temporarily stop the state-owned grain materials, plug shape or sand dune, and air flow along the pipeline, According to the given pressure, there are three types of air bulk transportation: suction type, pressure type and mixed type.

1、吸送式

1. Suction type

通风筒打开后，整个气力输送系统呈现一定的真空状态。在压差的作用下，气流使物料进入吸嘴，沿进料管输送到排料点的分离器。物料与空气分离后，由分离器底部排出。吸入式进料简单，可同时吸收多处物料，但输送距离比正压短，生产率低。

After the ventilation tube is opened, the whole pneumatic conveying system presents a certain vacuum state. Under the action of the pressure difference, the air flow makes the material enter the suction nozzle and transport it to the separator at the discharge point along the feed pipe. The material is separated from the air and discharged from the bottom of the separator. Suction feeding is simple and can absorb many materials at the same time, but the conveying distance is shorter than positive pressure and the productivity is lower.

2、压送式

2. Press type

鼓风机将空气压入输送管中，物料由送料机送出。将空气和物料的混合物沿输送管道压入排料处。物料经分离器排出，空气经除尘器净化进入大气。压力进料型的特点与吸力型相反，可以同时将物料输送到多个地方。输送距离长，生产率高，对沿途设备和管道密封要求高。

The blower presses the air into the conveying pipe, and the material is sent out by the feeder. The mixture of air and material is pressed into the discharge place along the conveying pipeline. The material is discharged through the separator, and the air is purified by the dust collector and enters the atmosphere. The characteristics of pressure feeding type are opposite to suction type, which can transport materials to multiple places at the same time. Long transportation distance, high productivity, high requirements for equipment and pipeline sealing along the way.

3、混合式

3. Hybrid

顾名思义，混合是两者的结合。与机械连续输送装置相比，混合气力输送物料是在完全封闭的条件下输送的，几乎不受气候和环境的影响。保证材料不受水分、污垢和搀杂的影响，有效改善现场工人的工作条件和工厂环境。

As the name suggests, mixing is a combination of the two. Compared with the mechanical continuous conveying device, the mixed pneumatic conveying material is transported under completely closed conditions, which is almost not affected by the climate and environment. Ensure that the materials are not affected by moisture, dirt and adulteration, and effectively improve the working conditions of workers on site and the factory environment.
