Abstract:
It is a subject to provide a nozzle device capable of effectively spraying air and capable of applying chemical solutions to a traveling body at a high deposition rate. For solving the subject, the present invention is a nozzle device 100 for applying a chemical solution Y to a traveling body 50 in a paper machine 101, the nozzle device 100 comprising a nozzle main body portion 2 having a chemical solution nozzle opening 1 capable of discharging the chemical solution Y, and an air main body portion 10 capable of spraying air from both sides of the nozzle main body portion 2 so as to put the discharged chemical solution Y between, wherein the air main body portion 10 includes an air introducing passage 13 for introducing air, a pair of front and rear flow passages 14 communicating with the air introducing passage 13 and a pair of air nozzle openings 12 communicating with each of the flow passages 14 for discharging air, and wherein a relationship between a cross-sectional area SA of the air introducing passage 13 and cross-sectional areas SB of the air nozzle openings 12 satisfies
Abstract:
Technical Problem generate extremely small particles of uniform diameter and reduce abrasive wear of the nozzle region Solution to the Problem The liquid ejecting device uses pressurized gas to eject liquid as a spray of fine particles and is provided with internal gas-flow passageway 3 to supply pressurized gas, and a nozzle section 10 with a slit-shaped liquid ejecting opening 12 to discharge liquid. The nozzle section 10 is near the end of an elongated main unit 1 of the liquid ejecting device, and gas jet openings 13 to discharge pressurized gas are established between inclined nozzle surfaces and sidewalls of the main unit 1. The liquid ejecting opening 12 is connected with liquid-flow passageway 2 and the gas jet openings 13 are connected with the gas-flow passageway 3. Viewed in cross-section, the inclined nozzle surfaces are formed such that their extensions intersect above the liquid ejecting opening 12 on a line extending from the liquid ejecting opening 12, and pressurized gas is discharged as jets along the inclined nozzle surfaces to intersect in a manner that sandwiches the liquid in between and breaks-up the liquid-flow to produce a spray of fine particles.
Abstract:
The subject matter of the present invention is a mobile spray gun, with which radiation curing can be initiated without the operator having to be protected from radiation. This is achieved by a mobile spray gun, comprising a feed channel 2 for a radiation-curable coating compound and a needle 1, which is movable in the longitudinal direction and with which the feed channel 2, which forms an annular gap around the needle 1, can be sealed with respect to the mouth 13 of the feed channel 2, wherein the needle 1 is designed such that it is transmissive to electromagnetic radiation with which curing of the radiation-curable coating compound can be initiated and/or the feed line 12 is designed to be transparent to electromagnetic radiation and a lighting unit 10 is fitted to the feed line 12.
Abstract:
An improved air atomizing spray gun (20) accommodates selective control over flows of air for atomizing liquid coating material into a conically-shaped spray and for forming the spray into a fan-shaped pattern. In one arrangement of the gun structure, respective supplies of atomizing (18) and fan-shaping (30) air are connected to the gun and separately coupled to atomizing (76) and fan air (80) outlet orifices. In another arrangement, only the supply of atomizing air is connected to the gun (20), and a valve on the gun adjustably diverts a portion of the atomizing air for fan-shaping purposes.
Abstract:
The present invention relates to an air cap arrangement and a spray gun. The air cap arrangement comprises an air cap (5), an air cap ring (6) and a retaining ring (7, 7'), wherein, the air cap ring (6) comprises a groove (62) configured to extend on the circumferential inner surface of the air cap ring (6); the air cap (5) also comprises a groove (52) configured to extend on the circumferential outer surface of the air cap (5), and the retaining ring (7, 7') is arranged in the groove (62) of the air cap ring (6) and the groove (52) of the air cap (5) to limit the axial movement of the air cap (5) within the air cap ring (6).
