Abstract
A pipe for the aeraulic transport of a loose-fill insulation product for a machine for blowing the insulating product, the pipe extending along a longitudinal main elongation direction and including at least one cylindrical wall which delimits a space configured for the circulation at least of the loose-fill insulating product, wherein, in the pipe, the cylindrical wall includes a plurality of sections, at least two of the sections each including at least one evacuation orifice so as to form at least two perforated sections, the pipe including at least two shutoff devices that are movable in translation along the longitudinal direction about the cylindrical wall, each of the shutoff devices being able to cover specifically one of the perforated sections.
Claims19
A pipe for the transport of a loose-fill insulating product for a machine for blowing the insulating product, the pipe extending along a longitudinal main elongation direction and comprising:
- at least one cylindrical wall which delimits a space configured for a circulation at least of the loose-fill insulating product, the cylindrical wall comprising at least a first end portion and a second end portion that are opposite ends from one another along the longitudinal direction, wherein, in the pipe, the cylindrical wall comprises a plurality of sections between its first end portion and its second end portion, at least two of the sections each comprising at least one evacuation orifice so as to form at least two perforated sections, the pipe further comprising at least two shutoff devices that are movable in translation along the longitudinal direction about the cylindrical wall, each of the shutoff devices being able to cover specifically one of the perforated sections,
- wherein the at least one evacuation orifice of each of the at least two perforated sections has a passage cross section less than or equal to 5 mm.
A pipe for the transport of a loose-fill insulating product for a machine for blowing the insulating product, the pipe extending along a longitudinal main elongation direction and comprising:
- at least one cylindrical wall which delimits a space configured for a circulation at least of the loose-fill insulating product, the cylindrical wall comprising at least a first end portion and a second end portion that are opposite ends from one another along the longitudinal direction, wherein, in the pipe, the cylindrical wall comprises a plurality of sections between its first end portion and its second end portion, at least two of the sections each comprising at least one evacuation orifice so as to form at least two perforated sections, the pipe further comprising at least two shutoff devices that are movable in translation along the longitudinal direction about the cylindrical wall, each of the shutoff devices being able to cover specifically one of the perforated sections,
- wherein the plurality of sections is formed on a module of the cylindrical wall which is arranged between the first end portion and the second end portion of the cylindrical wall of the pipe.
A machine for blowing a loose-fill insulating product, comprising:
- a blower comprising at least a base, the base comprising an air inlet, an inlet for receiving the loose-fill insulating product, and an outlet, said inlets being connected to the outlet by an air circulation channel and a circulation channel for the loose-fill insulating product, respectively, wherein the blower is constructed to mix air from the air inlet and loose-fill insulating product to generate a pressurized mixture comprising the air and the loose-fill insulating product for delivery through the outlet;
- a pipe fluidly communicated to the outlet for transporting the mixture and having a pipe outlet for output of the mixture, the pipe extending along a longitudinal main elongation direction and comprising:
- (a) at least one cylindrical wall which delimits a space configured for a circulation at least of the mixture comprising the air and the loose-fill insulating product, the cylindrical wall comprising at least a first end portion and a second end portion that are opposite ends from one another along the longitudinal direction, wherein, in the pipe, the cylindrical wall comprises a plurality of sections between its first end portion and its second end portion, at least two of the sections each comprising at least one evacuation orifice so as to form at least two perforated sections, and
- (b) at least two shutoff covers that are movable in translation along the longitudinal direction about the cylindrical wall, each of the shutoff devices being configured to selectively cover specifically one of the perforated sections to adjust an amount of air evacuating the pipe via the evacuation orifices and thereby adjust a pressure and flow rate of the mixture comprising the air and the loose-fill insulating product through the pipe.
