Pneumatic vacuum feeder is a common conveying equipment widely used in industries such as chemical, pharmaceutical, metallurgical, food, and building materials. Its main function is to transfer bulk materials from one container or storage hopper to another container or storage hopper through pneumatic vacuum equipment. Today, the editor will provide a detailed introduction to the structure and principle of the pneumatic vacuum feeding machine, in order to facilitate professionals in related industries to timely grasp relevant technical knowledge.
The pneumatic vacuum feeder mainly includes the following parts:
1. Feeding hopper: a container used for storing materials.
2. Filter: Used to filter impurities in materials.
3. Feeding valve: used to control the amount and time of material feeding.
4. Vacuum pump: generates strong vacuum suction to extract materials from the feeding hopper.
5. Pneumatic conveying device: Transport materials from the feeding hopper to the target through pipelines.
6. Control system: including electrical control, pneumatic control, and mechanical control, used to control the workflow of the pneumatic vacuum feeder.
The working principle of the pneumatic vacuum feeder is to use airflow and vacuum suction to extract materials from the feeding hopper and transport them to the target through a pneumatic conveying device. The specific steps are as follows:
1. The material in the feeding hopper is evenly fed into the pneumatic conveying device by controlling the feeding amount and time through the feeding valve.
2. Start the vacuum pump to generate vacuum suction, extract and pull the material from the pneumatic conveying device, form an airflow, and filter out impurities in the material through a filter.
3. Under the action of airflow, materials are transported along the pipeline to the target storage hopper or container.
4. The control system adjusts the conveying efficiency of the pneumatic vacuum feeder by controlling parameters such as the feeding amount of the feeding valve, the suction force of the vacuum pump, and the conveying speed of the pneumatic conveying device and pipeline as needed.
