With Movable Or Manipulable Means Controlling Escape Of Residue Patents (Class 55/432)
  • Patent number: 12090492
    Abstract: The invention relates to an air filtration bank (100) and an air filtration system (50) for removing grit or impurities from an airstream using a plurality of cyclonic air classifiers (10) arranged in 2×2 arrays in each air filtration bank (100). The system (50) comprises a plurality of interconnected, modular air filtration banks (100) arranged side-by-side and a grit collecting chute (5). In order to improve airflow efficiency and particle separation, each cyclonic air classifier (10) includes a vortex-inducing inlet duct (13), an extraction pipe (16) and a conical diffuser (15). The conical diffusers (15) of upper and lower cyclonic air classifiers are of different lengths such that their respective waste outlets are not coplanar which serves to limit waste outlet flow interference and results in less pressure drop across the air filtration bank, which in turn leads to more efficient particle removal.

  • Patent number: 8535402
    Abstract: A particle reduction system and method is disclosed having an air stream accelerator, a feeder assembly, a variable speed wheel lock operably associated with the feeder assembly for releasing raw material into a conveying air stream created by the positive displacement pump, and a particle conditioning assembly. The raw material is carried by the conveying air stream through the particle conditioning assembly, where particle of the material are collided with each other for the purpose of reducing the size of the particles. In some embodiments, a non-thermal drying system can be used to extract moisture from the raw material. The moisture/solids separation occurs, in large part, due to a head-on collision of two conveying air streams. The collision creates a large squeezing force, much higher than a centrifuge or filter. This impact squeezing acts to squeeze the moisture out of the raw material.

  • Patent number: 8470064
    Abstract: A system for separating contaminants from an airstream, including a centrifugal fan and housing; a contaminant containment vessel mounted to an outer surface of the housing; and a diverter in the airstream downstream of the fan and within the housing, the diverter being configured to separate a portion of the airstream from a remainder of the airstream, accelerate the portion of the airstream towards the containment vessel, and thereafter guide the portion of the airstream towards the remainder of the airstream. The diverter preferably does not negatively impact the rated performance of the fan, such that a performance of the system is not measurably different than the rated performance of the fan and housing combination. The diverter may accelerate contaminants entrained in the airstream toward the containment vessel, thereby separating the contaminants from the airstream.

  • Patent number: 8337575
    Abstract: The present invention relates to a method and a system for treating polluted gases prior to their emission into the atmosphere. The system comprises a treatment chamber having an inlet for receiving polluted gas and an outlet for expelling treated gas, the treatment chamber including at least one treatment cell having a filtering layer for treating the polluted gas when the polluted gas comes in contact with the filtering layer. The system also contains a powder container connected to the treatment chamber such that air laden with the powder can flow to the treatment chamber to form a filtering layer on the at least one treatment cell. The system contains an air flow generator connected to the outlet of the treatment chamber and to the container which is connected to the treatment chamber, for causing air flow to the container, to the treatment chamber and in the environment.

  • Publication number: 20120304606
    Abstract: A dual storage dust collector for a vacuum cleaner has a hopper for receiving the dust from the vacuum and a dump tank for receiving the dust from the hopper. A valve between the hopper and the dump tank is operable whether or not the vacuum is running. Thus, whenever the valve is open, dust falls from the hopper into the dump tank and, whenever the valve is closed, the dump tank can be disconnected from the hopper and emptied without interruption of the vacuuming process.

  • Patent number: RE44213
    Abstract: The invention concerns a separator, wherein the mixture, after passing through the inlet channels of the container body (1), penetrates into the admission chamber (30) of the rotor (2), where blades (35) arranged in star formation and perpendicular to the axis of rotation produce a centrifugal propulsion and, further, compact the components with greater density, thus facilitating extraction thereof. The thus modified mixture passes into the separating chamber (31), where blades (36) arranged in star formation and parallel to the axis of rotation, through their centrifugal force, push the components with greater density outwards; the latter having penetrated into the collecting cells (41) of the grid (34) which is coated on the outside of the separating chamber, through holes (42) exit from the rotor upon reaching the accumulation chamber (13). The fluid medium which, countered by a suitable pressure, cannot penetrate into the accumulation chamber, exit through evacuation channels.
