Abstract (en)
[origin: WO2017215947A1] The present invention concerns a bell (9) forming a device that both blasts shot and sucks up the blasted shot, with a casing dedicated to guiding (91) the shot clearly separated from a containment casing (92), which allows very high speed blasting of the shot particles and suction at a very high flow rate, while avoiding the risk of sucking up at least a portion of the shot before it impacts on the surface of the wall to be cleaned. The configurations of the bell according to the invention also allow a high level of productivity to be achieved. The invention more particularly concerns a robot (1) for renovating and/or inspecting a pipe, in particular a pressure pipe, provided with such a bell.
