Product Introduction

Vacuum feeder machine, also known as vacuum conveyor, is a dust-free closed pipeline conveying equipment that uses vacuum suction to convey particles and powdered materials. It uses the pressure difference between vacuum and ambient space to form gas flow in the pipeline, drive the movement of powdered materials, and thus complete the conveying of powders. my country has introduced advanced foreign vacuum technology, continuously improved and improved it, and it is now widely used in chemical, pharmaceutical, food, metallurgical, building materials, agricultural and sideline industries and other light and heavy industries.

Vacuum feeder machine is a closed pipeline conveying method. This conveying method can eliminate dust environmental pollution, improve the working environment, reduce environmental and personnel pollution to materials, and improve cleanliness; because it is pipeline conveying, it occupies a small space, can complete the powder conveying in a small space, and make the workroom space beautiful and generous; especially not limited by long and short distances. At the same time, the vacuum feeder can reduce the intensity of manual labor and improve work efficiency; it is the first choice for most powder material conveying methods.

Working Principle

The working principle of the vacuum feeder machine is as follows: it generates a vacuum through a vacuum pump (based on the Venturi principle), and then uses the negative pressure generated by this vacuum to suck the material from the feed port. In the filter bin of the separation container, the air and the material are effectively separated. The material falls automatically due to gravity and is collected in the silo. In particular, the cyclone separator of the powder vacuum feeder is designed to prevent fine powder from entering the filter, thereby improving the efficiency of the filter.

When the silo is full of material, the vacuum pump is automatically turned off to achieve pressure balance in the conveying equipment. Subsequently, the discharge valve is opened, and the material flows out through the discharge port and falls directly into the storage container. During the discharge process, the filter element is automatically cleaned by the back-blowing airbag. When the material is discharged, the discharge chamber is automatically closed, thus starting the entire conveying process.
