The mixture has good fluidity, which allows it to enter the conveying pipeline smoothly, ensuring the smooth operation of the conveying system. The material conveying is controlled by gas support, and its valve body and valve have good wear resistance.
The negative pressure system of the rotary feeder refers to a conveying system that uses a pressure fan to generate negative pressure in the system, and pumps the powder and granular materials uniformly mixed with air at the receiving device through pipelines to the storage device. It is mainly used in the ash treatment system of coal-fired power plants, also known as the negative pressure pneumatic ash removal system. Its system design technology has been fully mastered by domestic ash removal system designers. The negative pressure pneumatic conveying system has lower investment and can be used for multi-point feeding, requiring smaller net clearance at the lower part of the ash hopper.
The rotary feeder pneumatic spraying equipment is mainly used for low-pressure continuous pneumatic conveying. Its principle is that when the airflow enters the jet feeder and is sprayed out by the nozzle, a certain degree of vacuum is formed in the mixing chamber due to the throttling effect, so that the material is sucked into the mixing chamber and transported. The pneumatic spraying pump transports the material by the high-speed airflow sprayed out by the nozzle and transfers a part of its energy to the material. After the air and material mix into the mixing chamber, the speed of the mixing chamber is balanced.
The material conveying valve of the rotary feeder, as the conveying valve of the receiver, is one of the key equipment in the negative pressure system. Its function is to evenly mix the ash in the ash hopper with the air through the operation of the air supply valve and the ash volume adjustment device on the material conveying valve
