  • Trenchless multi-stage pipe cleaning device and method combining artificial tornado and dagger-like mechanical sand
    Patent number: 12285784
    Abstract: A trenchless multi-stage pipe cleaning device and method combining an artificial tornado and dagger-like mechanical sand is provided. The trenchless multi-stage pipe cleaning device includes a primary pipe cleaning device and a secondary pipe cleaning device that are connected. An outer wall of the pipe cleaning device is provided with multiple air inlet joint pipes evenly distributed in a circumferential direction. The air inlet joint pipes are connected to an air compressor. Each of the air outlet joints is connected to a nozzle. The primary pipe cleaning device is connected to a vibrating screen. The trenchless multi-stage pipe cleaning device further includes a back-end sewage discharge device. In the trenchless multi-stage pipe cleaning method, the mechanical sand continuously scrape and collide with the inner wall of the cleaning target, so as to achieve a desired efficient trenchless water-free pipe cleaning effect.
