Overview
This patented baghouse filter system—drafted and prosecuted with technical rigor by our team—addresses particulate handling for service vehicles such as vacuum trucks. Filed in February 2019 and granted in November 2021, the disclosure from inventors based in Navasota, TX describes a compact, single-vessel arrangement that integrates a rotatable head and lower assembly, an internal shell with protruding bag filters, and coordinated inlet/outlet flow paths. The design creates a cyclone-like lower cavity and distinct upper cavity separated by a planar upper surface, enabling efficient debris separation and staged filtration while remaining mounted on a service vehicle.
The patent claims emphasize practical serviceability and robust operation: hinge and latch assemblies allow quick open/close access, bag filter cages and textile bag portions capture ash and particulates, and bag blower rings with a blowdown inlet pipe permit in-situ pulse cleaning. Compared to multi-vessel approaches, the single-vessel cyclone effect reduces complexity and improves particulate settling within the lower cavity, enhancing uptime for field operations.
Key Features
- Service-vehicle-mounted baghouse with hinged head and latches for easy access
- Distinct lower and upper cavities with bag filters filtering airflow between them
- Bag blower rings and blowdown inlet for on-board filter cleaning
- Protruding bag filters with cages and textile media for reliable particulate capture
- Ducting aperture and stepped upper surface for optimized debris routing
By combining vehicle integration, refined airflow management, and practical maintenance features, this patented system advances industrial filtration for mobile cleanup and process-support applications, reinforcing performance and regulatory compliance across relevant sectors.
