Blow-Through Rotary Airlock Valve

The Blow-Through Rotary Airlock Valve is a high-efficiency feeding and unloading device specifically designed for direct-blowing powder conveying applications. Leveraging the company's years of experience in bulk material handling technology, it breaks through the limitations of traditional rotary valves and adopts a direct-blowing structural design to achieve "direct conveying, no retention, and low loss" of materials. It also features high efficiency, energy saving, excellent sealing, and strong adaptability, making it widely applicable to various powder handling scenarios requiring direct-blowing conveying. It is the preferred high-efficiency conveying equipment for industries such as chemical, new energy, building materials, and grain.

As the core hub of a direct-blowing powder conveying system, this product focuses on two core functions, connecting the storage and conveying links to ensure the efficient operation of the production line:

Direct-blowing feeding conveyor : Adopting an integrated direct-blowing structure, the material enters the rotary valve directly from the storage equipment and is precisely pushed to the conveying pipeline by the rotation of the impeller. There is no intermediate transition link, which reduces material retention and loss and greatly improves conveying efficiency.

High-pressure sealed unloading : Suitable for high-pressure direct blowing conveying conditions, it has excellent sealing performance, which can prevent material leakage and avoid dust pollution in the workshop, and also block the backflow of high-pressure gas in the conveying pipeline, ensuring the pressure stability of the direct blowing system and ensuring the continuity of conveying.

1. Direct airflow with no stagnation, resulting in higher conveying efficiency.

The optimized direct-flow channel design ensures a tight fit between the valve core and the valve cavity, preventing material residue and accumulation during passage, thus avoiding material clumping and deterioration, and reducing material loss. Compared to traditional rotary valves, the conveying efficiency is increased by more than 30%, making it suitable for the continuous conveying needs of high-volume production lines.

2. High-pressure sealing, suitable for complex working conditions.

Adopting a double-sealing structure and high-precision machining process, its sealing performance far exceeds industry standards. It can be adapted to 0.1-0.6MPa high-pressure direct blowing conditions, effectively preventing high-pressure gas backflow and powder leakage, taking into account both environmental protection and system stability, and is suitable for various high-pressure direct blowing conveying systems.

3. Wear-resistant and corrosion-resistant, suitable for various powder materials.

The parts in contact with materials are made of high-quality materials such as wear-resistant alloy steel and anti-corrosion coating. Special treatments are applied to powders with different characteristics (such as corrosive chemical powders, high-hardness mineral powders, and sticky powders), resulting in excellent wear resistance, corrosion resistance, and anti-sticking properties, extending the service life of the equipment and reducing maintenance costs.

4. Compact structure and easy installation

With its compact design, small size, and minimal installation space, it can be flexibly installed in various locations such as under storage silos and at the inlet of conveying pipelines. Its standardized interface design allows for seamless integration with existing direct-blowing conveying systems and storage equipment without complex modifications, resulting in high installation efficiency.

5. Intelligent and stable, with low operation and maintenance costs.

It features low vibration and noise during operation, enabling it to work continuously and stably for extended periods with a low failure rate. Its core components are modularly designed, allowing for quick disassembly and replacement of vulnerable parts such as impellers and seals. Daily cleaning and maintenance require no specialized tools, significantly reducing operation and maintenance time and costs.

Designed specifically for high-pressure direct-fire and high-efficiency conveying applications, it is widely used in industries such as chemical, new energy, building materials, grain processing, feed production, and mining, and is especially suitable for:

• Feeding and unloading processes in high-pressure dilute/dense phase direct-blown pneumatic conveying systems;
• Direct blowing conveying of viscous, easily caking powders (such as flour, starch, chemical additive powders, etc.);
• Continuous feeding and conveying processes in high-volume production lines (such as cement powder, mineral powder, feed powder, etc.).
• Precision powder handling scenarios with strict requirements on material loss and conveying efficiency.
