Vacuum conveyor is a dust-free closed pipeline transportation equipment that uses vacuum suction to transport granular and powdery materials. It uses the air pressure difference between the vacuum and the ambient space to complete the transportation of powder.Vacuum pipeline conveyor is widely used in various light and heavy industrial industries such as chemical industry, pharmaceuticals, food, metallurgy, building materials, agricultural and sideline industries. What are the working principles of vacuum feeder? Negative pressure is generated through high-pressure fans, Roots blowers, water ring vacuum pumps, vacuum generators, etc., and the air pressure difference is used to drive material movement to form vacuum logistics.The material is sucked into the vacuum transportation through the pipeline by negative pressure. In the feeder, the filter element isolates the material from the negative pressure air. After the negative pressure stops, the material is discharged by its own weight and enters the next process. At the same time, when the material is discharged, the positive pressure turns on the backflush, which blows away the material attached to the surface of the filter element and the material attached to the inside of the machine.After the discharge and backflush steps are completed, the discharge valve is closed, and the negative pressure and feed valve are opened for the next suction process. The use of vacuum conveyor can greatly reduce dust pollution in the workshop, improve cleanliness, significantly increase productivity, and save manpower.
