Rotary valve feeder

Rotary valve feeder

• The rotary feeder is also called a rotary valve, a star feeder, and an air lock.
• The usual structure of a rotary feeder is that a rotor with several blades rotates in a cylindrical casing. Materials fall from the upper hopper and are filled.
• In the space between the blades, it is discharged as the blades rotate to the lower part.
• There is a pressure equalizing exhaust port on the side of the body, which can discharge the high-pressure gas brought by the rotation of the impeller, reducing the phenomenon of gas pushing and conducive to the smooth flow of materials.
• The drop is one of the main components of the pressure-feeding and suction-feeding pneumatic conveying systems, and the rotary feeder type. It can feed materials into the clinker pipe evenly and continuously, and in the separation and dust collection part of the system, it It also has the functions of unloader and air lock.

Rotary feeder working principle

• The working principle of the rotary feeder is that the driving device drives the spiral scraper or the turntable to rotate.
• The material is pushed and frictioned by the spiral scraper or centrifugal force, and is continuously transported or transported upward along the movement direction of the spiral scraper or turntable.
• It is thrown away from the turntable and finally discharged from the discharge port or falls freely in the air to realize the transportation and diffusion of materials.
• Rotary feeder, also known as rotary feeder, is a commonly used material conveying equipment and is widely used in mining, building materials, chemical industry, metallurgy and other industries.
• It uses a rotating spiral scraper or turntable to transport materials from the bottom of the container or the turntable to the upper discharge port or throw them away from the turntable to achieve continuous feeding and transportation of materials.
• This kind of equipment consists of spiral scrapers, bearings, transmission devices, etc. Its working principle is simply to use friction and pushing to transport materials along the movement direction of the spiral blades or turntable through the rotating spiral blades or turntable. .
• Specifically, when the drive device is started, it drives the spiral scraper or turntable to rotate. Material falls from the upper hopper and fills the space in the spiral scraper or turntable. As it rotates, the material is pushed and rubbed, and is continuously transported upward along the movement direction of the spiral scraper or turntable.
• When the material reaches the edge of the turntable, it will be discharged from the discharge port, or it will fall freely in the air to realize the transportation and diffusion of the material. This design not only ensures the uniform transportation of materials, but also reduces the phenomenon of gas ejection, which is conducive to the smooth falling of materials.
• In addition, the rotary feeder also has the characteristics of simple structure and easy maintenance. It can be customized according to different production needs, so it plays an important role in the production line.
