Airslide fabric plays a critical role in the transportation of fine powders in pneumatic conveying systems, but buildup of material on the fabric can impede its effectiveness over time.
Airslide fabric is designed to move products through a pipeline with minimal resistance. However, over time, powders can accumulate and form a layer on the fabric, creating blockages and reducing the fabric’s efficiency. Scheduled cleaning helps to remove excess material and maintain proper airflow in the system.
Airslide Fabric :Top 3 Cleaning Methods
Several methods can be used to clean airslide fabric in pneumatic conveying systems, including the following:
- Air Blowing: The simplest method of cleaning airslide fabric is to use a reverse flow of air to blow the system clean. This method typically involves introducing an opposite flow of air to the normal direction of the conveying flow to dislodge any material that has adhered to the surface of the fabric.
- Reverse Pulse Jet: Reverse pulse jet involves periodically blowing compressed air through the airslide fabric in quick, high-pressure pulses. The sudden release of air dislodges any buildup of material and forces it out of the system. This method is effective for cleaning airslide fabric in systems with high volume or where powders tend to adhere to the surface of the fabric.
- Mechanical Agitation: Another method for cleaning airslide fabric is to use mechanical agitation, such as a rotating brush or paddle, to loosen any material that has clung to the surface of the fabric. This method is typically more labor intensive than the air blowing or pulse jet methods, but it is more effective for removing heavy or sticky materials.
| Cleaning Method | Advantages | Disadvantages |
| Air Blowing | Easy and quick | Not effective for heavy or sticky materials |
| Reverse Pulse Jet | Effective for heavy or sticky materials | Requires compressed air and more expensive equipment |
| Mechanical Agitation | Effective for heavy or sticky materials | Requires more labor and time |
Tips for Effective Cleaning of Airslide Fabric:
- Plan regular cleaning schedules, depending on the materials used and the frequency of use.
- Prior to cleaning, ensure the system is depressurized to avoid injury to personnel and equipment damage.
- Follow the manufacturer’s instructions and safety procedures when using chemical cleaners.
- Use compressed air that is filtered and dehumidified to prevent excess moisture from damaging the fabric.
Conclusion
Regular cleaning and maintenance of airslide fabric is essential for ensuring the safe and efficient operation of pneumatic conveying systems. Various cleaning methods are available, including air blowing, reverse pulse jet, and mechanical agitation.
Each method has its advantages and disadvantages, and the choice depends on the properties of the materials being conveyed. By following some simple and effective cleaning tips, pneumatic conveying system users can maintain optimal performance of their airslide fabric and minimize the risk of blockages or damage.
