  • Statement 95 The method according to Statement 94, further comprising controlling a rate at which compressed fluid is provided for the jets of fluid flow to modulate one or more of a strength of the jets of fluid flow, timing of the jets of fluid flow, or one or more other characteristics associated with the jets of fluid flow.
  • Statement 96 The method according to any one of Statements 78-95, further comprising removing a portion of the material extracted from the material source from the sound attenuation chamber and conveying the portion of the material extracted from the sound attenuation chamber to a material collector configured to receive material extracted from the material source.
  • Statement 97 The method according to Statement 96, wherein the sound attenuation chamber comprises one or more chamber sensors configured to generate signals indicative of one or more of filtration capacity of filter media at least partially enclosed in the sound attenuation chamber, a level of the material extracted from the source of the material in a chamber interior volume of the sound attenuation chamber, or a flow rate of the material out of a discharge port, and the method further comprises: receiving, via a chamber controller, one or more sensor signals from the one or more chamber sensors; and controlling, via the chamber controller based at least in part on the one or more sensor signals, operation of one or more of a discharge port control valve actuator or one or more jet generators configured to generate jets of fluid flow directed toward the filter media to at least partially maintain filtration capacity of the filter media, to one or more of facilitate flow of fluid through the filter media or prevent the chamber interior volume from being overfilled with the material.
  • the sound attenuation chamber comprises one or more chamber sensors configured to generate signals indicative of one or more of filtration capacity of filter media at least partially enclosed

Abstract

Ensembles et procédé d'extraction d'un matériau (16) à partir d'une source de matériau pouvant inclure un ensemble collecteur de vide et de matériau (200) pour améliorer l'extraction du matériau à partir de la source de matériau. L'ensemble collecteur de vide et de matériau peut comprendre un collecteur de matériau (36) comprenant un récipient sous pression à haut volume possédant une chambre intérieure et une source de vide à haute pression (36) couplée pneumatiquement au récipient sous pression. La source de vide est utilisable pour générer un vide à haute pression d'un écoulement de fluide à travers l'intérieur de la cuve sous pression pour extraire les déchets de la source de déchets vers l'intérieur de la cuve sous pression. La source de vide peut être reliée à la cuve sous pression du collecteur de matériaux pour former un ensemble unifié de vide et de collecteur de matériau pouvant être monté sur un seul châssis mobile (102).
