摘要： Methods for storing and moving adhesive particulate to an adhesive melter are disclosed. An interior space of a supply hopper is filled with adhesive particulate. A transfer pump is actuated to generate a vacuum at an inlet of the transfer pump to actuate removal of the adhesive particulate from the supply hopper. A consistent minimized depth of the adhesive particulate located directly above the inlet is maintained with a shroud located within the interior space of the supply hopper. In addition, adhesive particulate can be received in an interior space of a container. An open space is maintained within the interior space of the container proximate the pump inlet, where the open space entrains gas to be drawn by the transfer pump. The transfer pump can be actuated to generate a vacuum at the pump inlet to cause removal of the adhesive particulate from the container.

摘要： A powder feeding device, in particular for coating powder, is disclosed. The powder feeding device includes a dense phase powder pump which has at least one conveying chamber with a powder inlet valve and a powder outlet valve. Furthermore, a control device is provided for selectively operating the dense phase powder pump in a powder conveying more or a flushing operating mode. The powder inlet valve and the powder outlet valve of the dense phase powder pump are configured in each case as a pneumatically actuable compression valve which can be closed when an actuating pressure is applied. The control device is configured to set the pressure value of the actuating pressure which is selected for closing the powder inlet valve and/or powder outlet valve depending on the respective operating mode of the dense phase powder pump and/or depending on a pressure which prevails in the conveying chamber.

摘要： A multi-port metering pump assembly includes a manifold coupled to a metering pump. The manifold defines a central passage in fluid communication with a plurality of intermediate passages defined in the manifold. The manifold includes a plurality of outer passages. Each intermediate passage provides fluid communication between the central passage and a corresponding outer passage. A plurality of valves is coupled to the manifold. Each valve of the plurality of valves is located between an intermediate passage and a corresponding outer passage, and is configured to enable or prevent passage of fluid between a corresponding intermediate passage of the plurality of intermediate passages and a corresponding outer passage. The multi-port metering pump assembly also includes an electronic controller coupled to the plurality of valves, the electronic controller having an associated electronic interface and being programmable to selectively and independently open and close the valves of the plurality of valves.

摘要： A transfer pump for moving pellets of adhesive includes a pump housing with an adhesive inlet coupled to a supply hopper, an adhesive outlet coupled to an outlet hose, and an adhesive passage extending between the adhesive inlet and the adhesive outlet. A first air nozzle communicates with the adhesive passage adjacent the adhesive inlet and expels a first air jet that pushes pellets of adhesive through the adhesive passage. A second air nozzle communicates with the adhesive passage between the adhesive inlet and the adhesive outlet and expels a plurality of second air jets that draw pellets of adhesive through the adhesive passage by a vacuum force. The first and second air nozzles prevent clogging of pellets in the adhesive passage and enable movement of larger pellets than either air nozzle individually.

摘要： A tubular or cylindrical unit that creates a vortex effect with externally supplied pressurized fluid injected angularly within a transport structure is provided. Such a unit is utilized to either accelerate the vacuum and/or air conveyance of liquids, solid aggregates, and gases, reduce the energy required for such materials transport processes, or both. Such a result is achieved through the introduction of pressurized fluid via a plurality of injectors situated evenly around the circumference of the subject tube, pipe, and/or cylinder, and angled uniformly for an even pressure injection of fluid within the conveyance component thereof. In effect, through such injection of pressurized fluid, the overall transport system may be operated at significantly reduced cost while increasing the efficiency of overall vacuum and air conveyance systems simultaneously. The method of utilization of such a device is also encompassed within this invention.
