Vacuum Conveyor

Product description

The big-bellied vacuum feeder is a device that conveys materials by means of vacuum suction. Its main body is usually a cylindrical tank, and its "big-bellied" structural design enables it to have a large capacity for material storage and conveying. During operation, a negative pressure environment is created through a vacuum pump to draw materials into the tank from the feeding port. Once the set material level height is reached, the control system automatically switches and uses air pressure to transport the materials from the discharging port to the designated position. The entire process can be automated and has the advantages of high conveying efficiency, good sealing performance, and prevention of material moisture and contamination. It is widely applied in the conveying and feeding processes of powder and granular materials in industries such as chemical engineering, food, pharmaceuticals, and plastics.

Working principle

The Dadu vacuum feeder operates based on the principle of vacuum negative pressure and air pressure difference. After startup, the vacuum pump creates negative pressure in the tank. The external atmospheric pressure sucks the material in from the feeding port. The air and material are separated by the filter element. When the material level sensor detects the set height, the pump stops to maintain pressure. Subsequently, compressed air is introduced to convert the tank to positive pressure. Under the push of air pressure, the materials are conveyed from the discharge port to the target position. After the conveying is completed, the residue can be cleared by reverse blowing. Through the PLC control system, the automatic suction, storage and feeding of materials are realized in a cycle. It has the characteristics of high efficiency and energy saving, good sealing performance and anti-pollution, and is widely used in the feeding of powder and granular materials in the food, pharmaceutical, chemical and other industries.

Product features

- High degree of automation: The entire process of material suction, storage and feeding is fully automated through the PLC control system. Time and air pressure parameters can be precisely adjusted to adapt to the characteristics of different materials, reducing manual intervention and improving production efficiency.
- High conveying efficiency: By utilizing vacuum negative pressure and air pressure difference for cyclic operation, the suction and feeding speeds are fast, especially suitable for continuous feeding of powder and granular materials, reducing the material transmission time.
- Excellent sealing and cleanliness: The equipment is designed with an overall sealed structure to prevent material leakage and external contamination. It is equipped with a filtering device to separate air from dust, meeting the strict hygiene standards of the food, pharmaceutical and other industries.
- Energy conservation and consumption reduction: The energy consumption in the negative pressure suction stage is concentrated in the vacuum pump, while in the positive pressure conveying stage, the residual pressure of compressed air can be utilized. Compared with traditional mechanical conveying (such as screw conveyors), it has lower energy consumption and more economical operating costs.
- Wide applicability: It can convey various powder and granular materials such as flour, sugar powder, plastic pellets, and chemical powder, and supports flexible short-distance layout to meet the feeding requirements of different production lines.
- Easy maintenance: Some models are designed with a quick-release structure, making it convenient to replace vulnerable parts such as filter elements. Daily cleaning is simple, reducing downtime for maintenance.
- Safe and reliable: No mechanical rotating parts come into direct contact with the materials, avoiding the risk of heat generation or dust explosion due to friction, enhancing production safety, and is especially suitable for scenarios involving flammable and explosive materials.
