Filter System
Patent Number: US 11173441 Grant Date: 2021-11-16 Filing Date: 2019-02-21
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.
Invention Details
Abstract: A filter system. The filter system comprises a baghouse head assembly, a baghouse lower assembly and a baghouse inside shell assembly. The baghouse head assembly and the baghouse lower assembly are configured to selectively close and open between an open configuration and a closed configuration. The baghouse inside shell assembly comprises an upper surface and a one or more bag filters. The filter system comprises a lower cavity and an upper cavity. The lower cavity comprises a space between a side portion of the baghouse lower assembly and a shell of the baghouse inside shell assembly. The upper cavity comprises a space between the upper surface of the baghouse inside shell assembly and a lid portion or the baghouse head assembly. The one or more bag filters are configured to filter air flow between the lower cavity and the upper cavity.
Summary of the Invention: A filter system. Said filter system comprises a baghouse head assembly, a baghouse lower assembly and a baghouse inside shell assembly. Said baghouse head assembly and said baghouse lower assembly are configured to selectively close and open between an open configuration and a closed configuration. Said baghouse inside shell assembly comprises an upper surface and a one or more bag filters. Said filter system comprises a lower cavity and an upper cavity. Said lower cavity comprises a space between a side portion of said baghouse lower assembly and a shell of said baghouse inside shell assembly. Said upper cavity comprises a space between said upper surface of said baghouse inside shell assembly and a lid portion or said baghouse head assembly. Said one or more bag filters are configured to filter air flow between said lower cavity and said upper cavity. An inlet and an outlet are in fluid connection with one another through said lower cavity, said one or more bag filters and said upper cavity.
