Calcium powder transportation site of Roots blower in Chizhou, Anhui
The figure below shows the user site in Chizhou, Anhui Province, Roots blower The matching unloader is used to transport calcium powder, and the matching fan is used Msr150 roots blower It is a 37KW motor with 10 tons of calcium powder per hour.
1. Features of pneumatic conveying device:
In many modern chemical plants, pneumatic equipment is used. Pneumatic conveying device is the first choice for many enterprises because of its large conveying range and high efficiency.
Pneumatic conveying device can be divided into suction conveying and blowing conveying (negative pressure and positive pressure) Roots blower It is essential in pneumatic conveying device.
Picture: negative pressure conveying system and positive pressure conveying system:
2、 Negative pressure conveying
One side of suction part of negative pressure fan has been completed; pressure state: under negative pressure, materials and dust will not overflow and disperse;
Characteristics of conveying materials: from multiple places to one place, it is suitable for conveying materials with large stacking area or low depth, and limited conveying capacity and distance. The feeding form is simple, and the air tightness of the dust remover is required to be high;
3. Positive pressure transportation
The pressure part of the fan has been completed; the pressure state: positive pressure, dust overflow;
Characteristics of material transportation: long distance, large flow, one place and many places; feeding mode: complex, when the conveying pressure is high, the upper box of the feeder needs to be made into a closed structure; the requirements of the unloader are simple.
The above is Roots blower A simple comparison between negative pressure and positive pressure in conveying materials shows that roots blower is not only suitable for conveying powder like cement, flour, lime powder, graphite powder, calcium powder, stone powder, talcum powder, etc. At the same time, it is also suitable for conveying small granular materials such as corn and wheat 。
