摘要:
A system usable for dispensing fluids including hot melt adhesives supplied from a reservoir onto a substrate. The system includes a fluid metering device having a plurality of metered fluid outlets for supplying fluid from the reservoir, a main manifold (100) having an end portion (102) with plurality of fluid outlet ports (32) coupled to corresponding metered fluid outlets of the fluid metering device, and a corresponding plurality of fluid return ports (42) coupled to the reservoir. At least one individual fluid flow control plate (200) having a plate fluid inlet port (220) on a plate fluid interface (210) is mountable on the end portion (102) of the main manifold (100) to couple the plate fluid inlet port (220) of the individual fluid flow control plate (200) to a corresponding one of the plurality of fluid outlet ports (32) of the main manifold (100). The individual fluid flow control plate includes a plate fluid outlet port (240) coupled to the plate fluid inlet port (220) by a plate fluid flow conduit (230) for either recirculating back to the main manifold (100) or directing the fluid to a fluid dispensing nozzle.

A system usable for dispensing fluids including hot melt adhesives, supplied from a reservoir, onto a substrate. The system includes a plurality of fluid dispensing nozzles coupled to a fluid supply conduits disposed in a main manifold wherein fluid is supplied from a fluid metering device. An air preheater module is mountable to the nozzles and provides heated air for controlling the fluid dispensed by the nozzles. The main manifold includes a plurality of recirculation conduits each disposed between a fluid supply conduit and the fluid reservoir. A one-way valve disposed along each recirculation conduit conditionally recirculates fluid toward the fluid reservoir. A variety of recirculation manifold configurations are interchangeably mounted to the main manifold for recirculating fluid toward the fluid reservoir. Fluid pressure gauges monitor pressure in individual fluid supply conduits, or alternatively an average fluid pressure. The fluid metering device is mountable in a well in the main manifold, wherein a common heating member heats both the main manifold and the fluid metering device.

There is provided a system and method to spray viscous coating materials comprising abrasive particles, such as Silicium Carbide. Such coating materials are e.g. advanced ceramic composites formulated to protect equipment from corrosion and erosion. In particular the method and the system is able to spray and evenly coat a surface with two component materials based on modified epoxy resin and aliphatic curing agent loaded with abrasive ceramic particles.

The invention concerns a spraying device comprising: a tubular base (28) open at its two ends; a reservoir of solution (17), a supply duct (29) starting from the reservoir and reaching up to the lower part of the nozzle, and a duct (30) of compressed carrier gas, in particular of compressed air, emerging into the nozzle in the proximity of the supply duct (29). The invention is useful for bactericidal treatment of bird carcasses (2) with a trisodium phosphate solution.

摘要:
The present invention comprises: a material tank 1 which contains therein a melted sulfur material as a spraying material; a warming heater 2 which is made temperature-adjustable so as to heat an outer peripheral portion of the material tank 1 within a setting temperature range equal to or higher than sulfur melting point and to retain the sulfur material in the material tank 1 in a melted state; and a spray nozzle 3 which is integrally mounted to the material tank 1 while being connected to a material outlet port on a lower end portion of the material tank 1 and is supplied with the compressed air, to inject the sulfur material in the material tank 1 together with the compressed air, wherein the sulfur material in the melted state is sprayed on a working surface. As a result, the spraying material comprised of the sulfur material which is solid at room temperature while it is melted to become a fluid state upon being heated to a temperature within a preset temperature range of which a lower limit is set to be equal to or above a melting point of the sulfur material can be consecutively sprayed on the working surface.
