Vacuum Feeder

Vacuum feeder is a kind of dust-free closed pipeline conveying equipment that uses vacuum suction to transport particles and powdery materials, and uses the air pressure difference between vacuum and environmental space to form gas flow in the pipeline and drive the movement of powdery materials, so as to complete the transportation of powder. The foreign vacuum technology introduced by China has been continuously improved and improved, and is now widely used in chemical, pharmaceutical, food, metallurgy, building materials, agricultural and sideline industries and other light and heavy industries.

Principle Introduction

A vacuum generator or vacuum pump is used to generate a vacuum, and the negative pressure generated by the vacuum sucks the material from the inlet. The air is then separated from the material in the filter bin of the separator vessel. The material falls automatically due to gravity and is collected in the silo. Our cyclones prevent fine powders from entering the filter to improve the efficiency of the filter.

When the silo is full of material, the vacuum pump automatically shuts down, and the pressure in the conveying equipment reaches equilibrium. The discharge valve is opened, and the material flows out through the discharge port and falls directly into the storage container. When discharging, the filter element is automatically cleaned by a back-blowing air bag. If the material is more viscous, we can install a special vibrator to assist in discharging. At the end of the blanking, the discharge compartment is automatically closed, and the whole conveying process is started again.

Equipment Advantages

• Smooth modular design: The modular design not only makes the installation and maintenance simpler, but also more convenient to disassemble and wash, and eliminates the existence of dead ends. When cleaning, the design of the clamps between the various modules of the equipment allows the conveyor to be easily removed and installed. The equipment does not have gaps and dead corners that are easy to accumulate materials.
• Fluidization device: The fluidizer is to produce a layer of air mold between the material and the inner wall of the conveyor silo, through which the air film can effectively help the flow of materials with poor fluidity, which not only prevents the material from bridging, but also improves the unloading efficiency. The fluidizer material is sintered polyethylene, which meets the requirements of FAD.
• Back-blowing system: built-in one-to-one back-blowing airbag, pulsed gas back-blowing, each cycle can efficiently clean the filter, making the equipment performance more stable.
• Filtration system: Japan Toray polyester coated filter element anti-static filter element, filtration accuracy up to 0.3 μm, maximum working temperature 130°C. Imported from Japan, it can be cleaned with alcohol, water, and compressed air, and can be used repeatedly for a long time.
