    摘要: Method and device (10) for mixing polyurethane—forming reactive chemical components; at least first and second chemical components (A, B) are introduced into a common pressure and feeding chamber, from where the chemical components are made to flow and co-injected through one or more narrow orifices (31) into a mixing chamber. During co-injection of the chemical components (A, B) a first mixing takes place into the jet strim, while a final intimate mixing is performed by impingement and collision into the mixing chamber (24) of the device; selectively actuable cleaning members (12, 29) eject the residual chemical material remaining into the common pressure and feeding chamber (15), and the mixing chamber (24) of the mixing device (10).

    摘要: A method and apparatus for feeding a polyurethane mixture suitable to form a thermally insulating layer inside hollow bodies, such as hollow walls of a refrigerator cabinet, freezer, display counter or insulating panel. A polyurethane mixture resulting from chemically reactive components, supplied by a high-pressure mixing device, is injected into a cavity of a hollow body extending in a horizontal plain. The mixture is injected at a first flow-rate and a first injection speed, to be poured into a first deposition zone farthest from the injection point. Subsequently, the flow-rate and the injection speed of the polyurethane mixture are gradually reduced in a controlled manner, to be poured in successive deposition zones towards the injection point of the polyurethane mixture, along a distribution strip, allowing the injected mixture to spread out throughout the cavity of the hollow body along isometric expansion lines.

The self-lubricating and scraping device comprises a delivery chamber for the lubricant material axially aligned and in fluid communication with the outlet duct; the lubricant delivery chamber is connected to a storage tank by a feeding and re-circulation circuit. The lubricant is sucked into the outlet duct and subsequently returned into the delivery chamber by a cleaning member in the form of a pumping piston sliding into the outlet duct, the pumping piston being provided with scraping rings for removing the reacted mixture adhered to the inner surface of the outlet duct.

    摘要: A high-pressure self-cleaning mixing apparatus adapted to mix at least first and second reactive polyurethane-forming components and feed the mixed components to a mold is disclosed. The apparatus includes at least a mixing chamber, first and second feed passages, first and second recycle passages, and a cleaning member having at least first and second longitudinally-extending recycle grooves spaced from each other. The cleaning member is movable between an open position in which the first feed passage radially feeds the first polyurethane-forming component to the mixing chamber and a closed position in which the first longitudinally-extending recycle groove communicates the first feed passage with the first recycle passage to recycle the first polyurethane-forming component instead of feeding the first polyurethane-forming component to the mixing chamber. The second feed passage may be communicated with a longitudinally-extending passage of the cleaning member to permit the second polyurethane-forming component to be fed into the mixing chamber along an axial direction of the mixing chamber. A valve member may be provided to prevent the flow of the second polyurethane-forming component to the mixing chamber by recycling the second polyurethane-forming component to the second recycle passage. Spacing between the first and second grooves seals the first feed and recycle passages from the second feed and recycle passages.

    摘要: An apparatus for mixing and ejecting fluid materials interacting with one another; said apparatus comprises at least a head having a mixing chamber with an outlet opening for the mixture at one end thereof, and having inlet ports, each of which connected to a supply line for a component. Each inlet port is connectable, through a distributing valve, with an orifice opening into the mixing chamber and respectively with an outlet port connected to a return line for a recycle at a first pressure rate of each component to a reservoir. A pin is reciprocable by a first double-acting cylinder to and away from the outlet opening of the mixing chamber; the distributing valves are operated by a second double-acting cylinder parallel connected to said first cylinder, one side of said second cylinder being directly connected to a pressure fluid source, and the other side being connected to pressure source by means of a shut off valve operable by the piston of the first cylinder at the end of its backward stroke. The return line for each of the components is further provided with a branched conduit having a valve defining a narrow orifice for a recycle at a higher pressure rate than the former.
