Air Slide Fabric

Cement tanker vent strips (linners) have the following main uses:

1. Balancing air pressure: During cement loading and unloading, changes in the state of the material inside the tank cause changes in air pressure. Linners allow air to flow smoothly in and out of the tank, preventing negative pressure from forming during unloading, which could hinder the smooth flow of material. Linners prevent excessive positive pressure during loading, ensuring tank safety and stable loading and unloading operations.

2. Preventing dust leakage: Liners have excellent filtering properties, allowing air to pass while effectively blocking cement dust. During loading and unloading operations, they reduce dust emissions, lower environmental pollution, improve the working environment, and protect the health of operators.

3. Protecting the tank structure: Abnormal air pressure inside the tank can damage it. Liners balance air pressure, reducing the pressure on the tank, extending its service life, and preventing structural damage such as deformation and weld cracking caused by air pressure issues. 4. Improved Transportation Safety: During transportation, the breather belt continuously balances the air pressure inside the tank, preventing safety incidents caused by unstable air pressure, such as tank rupture and material leakage, thereby enhancing safety during cement tanker transportation.

The cement tanker breather belt, also known as the cement tanker breathing belt, is a key component in the cement tanker unloading system.

Structure and Material

1. Structure: The breather belt is typically flat and installed at a specific location on the bottom of the cement tanker. Most are long strips, and some even cover a portion of the tank bottom to provide a wide ventilation area.

2. Material: It is primarily made of special chemical fiber fabrics, such as polyester and terylene. These materials offer excellent air permeability, effectively venting air from the tank. They also possess high strength and wear resistance, withstanding the impact of material flow and external friction. They are also chemically resistant and will not be damaged by alkaline substances such as cement.

Working Principle

When a cement tanker is unloading, compressed air enters the tank through a pipe, fluidizing the material inside to facilitate unloading. During this process, the air pressure inside the tank increases. The breather belt acts as an air vent, promptly discharging excess air, maintaining pressure balance, and preventing damage to the tank due to excessive pressure. Due to the small pore size and specialized structure of the breather belt, air can be discharged smoothly while preventing cement particles from escaping with the air, thus avoiding material waste and environmental pollution.

Purpose

1. Ensure Smooth Unloading: Continuously discharging air from the tank prevents excessive pressure from creating air blockage, which can hinder cement unloading. This ensures an efficient and stable unloading process and improves transportation and unloading efficiency. For example, if the breather belt is missing or blocked, unloading time may be significantly extended or even impossible.

2. Protect the tank: Prevent abnormal pressure increases within the tank, avoiding safety accidents such as tank rupture due to overpressure, and extending the tank's service life. In transportation scenarios where unloading is frequent and labor-intensive, the proper functioning of the breather belt effectively protects the tank.

3. Environmental Protection and Energy Saving: Preventing the emission of cement particles reduces dust pollution, complying with environmental requirements. It also prevents material waste, reduces transportation costs, and achieves energy savings. Maintenance and Care.

1. Regular Inspection: Before and after each unloading operation, inspect the breather belt for signs of damage, blockage, or aging. If any visible holes or extensive wear are found on the surface of the breather belt, replace it promptly.

2. Cleaning: Regularly blow the breather belt back with compressed air to remove any cement dust. A professional cleaning agent can also be used for soaking and cleaning, but care must be taken to avoid damaging the breather belt material. A thorough cleaning is generally recommended every 1-2 weeks.

3. Replacement Frequency: The breather belt replacement frequency varies depending on frequency of use and operating environment. Frequent use in harsh environments may require replacement every 3-6 months. In less frequent use in a favorable environment, the replacement period can be extended to 6-12 months.
