What role does the pneumatic conveying bin pump play in pneumatic conveying?

Bin pump, also known as bin pump, pneumatic conveying pump, or pneumatic conveying bin pump, plays an important role in pneumatic conveying. A bin pump is a pressure vessel that can withstand a certain pressure and temperature. The upper end of the bin pump is a pneumatic feed valve, and there is an upward pipeline inside that is connected to the pneumatic discharge valve and ash conveying pipeline. The bin pump operates in an automatic control mode and can be divided into four stages: 1. feeding stage, 2. pressure fluidization stage, 3. conveying stage, and 4. blowing stage. The specific details of the warehouse pump are as follows

How is positive and negative pressure pneumatic conveying implemented, and how should we choose?

Before understanding the positive and negative pressure pneumatic conveying system, everyone should understand the positive pressure pneumatic conveying system and the negative pressure pneumatic conveying system. The positive pressure pneumatic conveying system is: "The fan fully mixes the air and material in the pipeline, and the mixed material is pressed into the separator for separation in the pipeline. Finally, the conveyed material is discharged from the shoe material port at the bottom, and the air returns to the atmosphere after dust removal; So the negative pressure pneumatic conveying system is: "Take the air and powder particles inside the bin pump

How is negative pressure pneumatic conveying implemented and how should we choose it?

As we mentioned earlier about positive pressure pneumatic conveying, how is negative pressure pneumatic conveying used? Negative pressure pneumatic conveying refers to the pneumatic conveying system that uses a Roots blower (Roots vacuum pump) to thoroughly and uniformly mix the air and powder materials in the bin pump, and then pumps them through the pipeline to the material sealing pump. During the conveying process, the pressure value of the entire pipeline is lower than atmospheric pressure. The negative pressure pneumatic conveying system is one of the earliest practical applications in the entire pneumatic conveying system and is also quite feasible

What field is suitable for dilute phase pneumatic conveying system

We learned earlier that dense phase pneumatic conveying systems can transport materials from one or more aggregate points to one or more receiving points, and can transport various types of powder materials, such as powders, particles, mixtures, and other loose solid materials. Generally, the starting speed of dense phase pneumatic conveying is usually less than 10m/s, and the solid gas ratio is greater than 10:1. So what is dilute phase pneumatic conveying like. Dilute phase pneumatic conveying is a continuous and uninterrupted process where the pressure in the entire pipeline system exceeds the local air pressure
