Abstract:
Nozzles for converting clumps and nodules of dry or substantially dry fibrous insulation to pils and for spraying on the so treated and accelerated air entrained insulation pieces to form thermal and acoustical insulation in building cavities. The nozzles comprise a shredder section for reducing the size of many of the pieces of insulation to pil size and an accelerator section for increasing the velocity of a stream of air suspended pils for improved just-installed insulation integrity or strength. The shredder and the accelerator can also be combined in a single unit.
Abstract:
A honeycomb filter production apparatus includes: a workpiece securing section (10) for securing a base of a honeycomb filter (11); a powder transfer section (20) that is disposed on one side of the workpiece securing section (10), and transfers a powder together with an air current by utilizing pressurized gas; an introduction section (40) that is provided between the powder transfer section (20) and the workpiece securing section (10), the powder transferred from the powder transfer section (20) together with the air current being mixed with another gas in the introduction section (40), and introduced into the base secured by the workpiece securing section (10) when the apparatus is used; a suction section (30) that is disposed on the other side of the workpiece securing section (10), and sucks the gas that has passed through the base secured by the workpiece securing section (10) by reducing pressure on the other side of the workpiece securing section (10) as compared with the one side of the workpiece securing section (10) using suction means; a cleaning section (50) for removing a surplus powder adhering to an end face of the base after the introduction of the powder; a judgment section (60) for judging an amount of the powder adhering to the base; and a workpiece transfer section (70) for transferring the base among the workpiece securing section (10), the cleaning section (50), and the judgment section (60).
Abstract:
PROBLEM TO BE SOLVED: To provide a means which can manufacture a honeycomb filter having excellent quality, made by forming a collecting layer having a uniform thickness on the surface of a substrate made of a porous body, with a high yield.SOLUTION: A honeycomb filter manufacturing apparatus has a work fixing portion 10 for fixing the substrate, a powder transfer portion 20 disposed on one side of the work fixing portion 10 and transferring a powder together with an air flow by using a pressurized gas, an introduction portion 40 for further mixing the powder, transferred together with the air flow from the powder transfer portion 20, with another air flow between the powder transfer portion 20 and the work fixing portion 10 and introducing the powder to the substrate fixed to the work fixing portion 10 when the apparatus is used, a suction portion 30 disposed on the other side of the work fixing portion 10 and sucking the air flow, passing through the substrate, by reducing the pressure of the other side of the work fixing portion 10 relative to that of the one side thereof using a suction means, a cleaning portion 50 for removing excessive powder adhering to the end surface of the substrate after the introduction of the powder, a determining portion 60 for determining the adhering amount of the powder, and a work transfer portion 70 for transferring the substrate.
Abstract:
PROBLEM TO BE SOLVED: To inject aerosol toward a base material of a honeycomb filter from a plurality of different parts without complicating a structure of a powder conveyance part of a honeycomb filter manufacturing apparatus.SOLUTION: A nozzle 22 is attached to an injection side end of "an ejector for injecting aerosol" in a honeycomb filter manufacturing apparatus. The nozzle 22 comprises the shape having a longitudinal direction (X1), a single introduction port Ha is formed on one side end face in the longitudinal direction, and a plurality of discharge ports Hb are formed on the other side end face in the longitudinal direction. A single introduction passage 22a linearly extends in the longitudinal direction from the single introduction port Ha, each of the discharge passages 22b branches from an end on the opposite side of the introduction port Ha at the introduction passage 22a, and extends in a direction inclined from the longitudinal direction toward a corresponding discharge port Hb. When a ratio of the total sum of opening area of the plurality of discharge ports to opening area of the single introduction port is considered as α, and the number of the plurality of discharge ports is considered as n, 1≤α≤√n is established.
Abstract:
A nozzle (22) for delivering texturized fibrous material into a chamber of a muffler has a body (26) including a texturized fibrous material passageway (28) and a separate directional jet passageway (30). A method of filling a chamber of a muffler with texturized fibrous material includes the steps of extending a wand (20) into the muffler so that a nozzle (22) on the wand is received in the chamber, discharging a stream of texturized fibrous material into the chamber from a first passageway (28) of the nozzle and discharging a directional jet (50) into the stream of texturized fibrous material from a second passageway (30) of a nozzle (22) whereby the stream of texturized fibrous material is redirected into a desired filling direction (52) to more efficiently fill the chamber.
Abstract:
A dispenser (110) for a blown fibrous insulation delivery system which is attached to a fibrous material delivery conduit (114) of the system. The dispenser (110) includes a pipe (112) having a first end (122) which is attachable to the delivery conduit (114) and second end which carries a deflector (120) for compressing a flow of fibrous insulation discharged through the outlet of the pipe (112) and for changing the direction of flow of fibrous insulation compressed thereby. The deflector (120) includes a substantially planar portion disposed at an acute angle with respect to the pipe outlet (126). The dispenser (110) may also include a second deflector for changing the direction of flow of the compressed fibrous insulation.
