Definitions
- the invention relates to a fog generator head according to the preamble of claim 1.
- Such known fog generator heads are found e.g. use in devices with which the moisture content of
- Room air is increased, or also in industrial plants in which e.g. an oil film or a layer of adjacent oil droplets is applied to the surface of a workpiece.
- the known mist generators have in common that it is difficult to produce mist even from highly viscous liquids, because the gas jet striking the liquid stream emitted by the liquid nozzle can then no longer divide the liquid jet into individual droplets, since the cohesion in the liquid jet is too strong . It is also not possible to set the amount of fog generated in the known fog generators to very small values, since the atomization of the liquid by a gas jet requires a certain minimum throughput of liquid through the liquid nozzle and of gas through the gas nozzle.
- the present invention is therefore intended to develop a mist generator head according to the preamble of claim 1 in such a way that even small amounts of a higher-viscosity liquid are reliably atomized.
- the supplied liquid is forcibly divided into small packets by the valve body assigned to the liquid nozzle. These small volumes of liquid, which are released each time the valve body is opened, are then further torn apart by the gas flow, so that a fine mist is obtained overall.
- a good pre-division of the liquid in the liquid nozzle is obtained if the valve body cooperating with the liquid nozzle is operated with the frequency specified in claim 2.
- the pressure value specified in claim 3 for the liquid to be atomized and the pressure value specified in claim 4 for the gas are also advantageous with regard to fine, reliable atomization of the liquid.
- the geometry specified in claim 5 has the advantage that, on the one hand, the liquid droplets emitted by the liquid nozzle reach and pass through the gas jet, and on the other hand that the gas jet results in a certain concentration and spatial holding of the mist, and also that the mist generation as a whole is symmetrical and uniform.
- valve body associated with the liquid nozzle also acts as a deflector which distributes the liquid droplets emitted by the liquid nozzle in the circumferential direction.
- the droplet stream emitted by the liquid nozzle can widen somewhat before the dust is removed by the gas stream. This gives you better areas of attack for the gas flow.
- an injection nozzle unit as specified in claim 9, is used to implement the liquid nozzle and the valve body, then the favorable costs, the stability and the reliability of injection nozzles for internal combustion engines can be used for atomizing a liquid.
- the development of the invention according to claim 10 is advantageous both with regard to the compact design of the fog head generator and with regard to the uniformity of the generated fog.
- the cross-sectional shape of the mist flow can be easily increased or decreased.
- Figure 1 is an exploded schematic view of a plant for producing thin layers of oil on sheets to be fed to a press;
- FIG. 2 a transverse cross section through the oiling chamber of the system shown in FIG. 1;
- Figure 3 an axial section through a mist generator head, as used in the system of Figure 1;
- FIG. 1 shown fog generator head along the section line IV-IV;
- FIG. 5 a top view of the end face of the fog generator head according to FIGS. 3 and
- Figure 6 a view similar to Figure 4, but in which a fog generator head is shown with controllable fog flow cross section.
- 10 denotes the frame of an oiling station, designated overall by 12.
- a housing 14 is shown pulled down by an oiling device designated overall by 18. It comprises an upper housing part 16a and a lower housing part 16b, which together delimit an inlet slot 20 and an outlet slot 22, through which sheets to be oiled (not shown) can pass.
- the oiling station 12 is essentially symmetrical to the conveying plane of the sheets. Where necessary, functionally equivalent components located above or below the funding level are distinguished by suffixes a and b.
- a loading conveyor not shown in the drawing, and a discharge conveyor 24, which is only shown schematically in the drawing, are used for feeding and carrying away the sheet metal to be oiled. For the sake of clarity, the latter is shown, like the housing 14, apart from the actual oiling device 18.
- the oiling device 18 includes profiles 26, 28 which are transverse to the conveying direction of the sheets.
- One of the profiles 26 is (26a) above and the other (26b) is arranged below the conveying path of the sheets.
- a set of upper fog generator heads 34a and lower fog generator heads 34b is attached to profile 26a and 26b in a uniformly distributed manner in the direction transverse to the sheet metal conveying direction, via an obtuse-angled holding plate 30.
- Support rollers 38 carry the sheets to be oiled in the interior of the housing 14.
- the axes of the mist flows 40a, 40b generated by the mist generator heads 34a, 34b are tilted out of the vertical by approximately 15 in the direction of the sheet metal.
- guide plates 44 and 46 which are spaced from the housing walls and each have an obliquely upward and inward end section 48 and 50 at the lower end.
- a gap 52, 54 which is connected via lines 56, 58 to a suction channel 60, on which a suction fan, not shown in the drawing, works.
- the vertical walls of the housing parts 16a, 16b each have end sections 62, 64 at the lower end, which in pairs each form an inlet or outlet judge for the sheet metal to be oiled.
- the mist generator heads 34 each have a housing 66, in which a central, multiply stepped bore 68 is provided.
- An injection unit 70 is inserted into the stepped bore 68, as is used for fuel injection in diesel engines.
- the injection unit 70 has a housing 72 which is stepped several times on its outside and has a liquid nozzle 74 in its lower end face.
- the liquid nozzle 74 also specifies a frustoconical valve seat 76 which cooperates with a valve body 78 which is carried by a valve stem 80.
- valve stem 80 extends upward through the housing 72 and is at the top End connected to the armature of an electromagnet 82 which is excited by a control unit 84.
- This receives signals from a higher-order controller 86, which de frequency with which the electromagnet 82 is controlled, the duty cycle between the open and closing times of the valve body 78 and possibly the amplitude of the supply current given to the electromagnet 82 (and thus the opening path of the valve body 78 ).
- the gradation of the bore 68 and the gradation of the outer surface of the housing 72 define an annular space 88 in the lower section of the housing 76. This is connected via an inlet 90 to a compressed air line 92 m. This contains a pressure regulator 94.
- An air nozzle disk 96 is screwed tightly against the lower end face of the housing 66 by means of a threaded ring 98.
- the air nozzle disk 96 has in its upper boundary surface a truncated cone-shaped depression 100 which surrounds the lower end of the housing 72 with play and leads as a funnel to a likewise frustoconical nozzle opening 102 which opens out into the free end face of the air nozzle disk 96 below.
- a rare channel 104 branches off from the inlet 90, in which a frustoconical valve seat is provided, which cooperates with a needle valve body 106 having a conical tip, which runs in a thread of the housing 66 and can be actuated at a knurled end section 108.
- An axial control air duct 110 extends from the section of the side duct 104 located behind the valve seat formed in the rare duct 104 and leads to a further annular space 112 leads, which lies between the underside of the housing 66, the top of the air nozzle disk 96 and the inner surface of the threaded ring 98.
- Control nozzle ducts 126, 128 emanating from the annular space 112 open into the free end face of the air nozzle 96 and represent a continuation of the control air ducts 110, 124, as can be seen in FIG. 5.
- a liquid feed channel 130 of the injection unit 70 is connected to a distributor line 132, in which the liquid (oil) to be atomized is present at a pressure of 2 to 8 bar, preferably about 4 to 5 bar, via a pressure regulator 134.
- the pressure set in the compressed air line 92 by the pressure regulator 94 is approximately 2 to 4 bar.
- the pressure values used in each specific case depend on the type, in particular the viscosity of the liquid to be atomized in each case and the size of the desired droplets and the desired speed for the mist flow.
- control unit 84 excites the electromagnet 82 with the respectively set frequency and the respectively set duty cycle. With each excitation of the electromagnet, a predetermined small volume of liquid is dispensed through the liquid nozzle 74, and at the same time it is pre-atomized. When leaving the liquid nozzle, these liquid droplets come into intimate contact with the sleeve-shaped air jet flowing around the lower end of the injection unit 70 and are further torn open in the latter. A fine liquid mist is obtained at the outlet of the nozzle opening 102.
- the mist cone can be flattened from two opposite sides, so that the transverse mist cross-section takes on a rectangular shape.
- the needle valve body 106 is mounted displaceably in the axial direction in the housing 66 and is firmly connected to the armature of an electromagnet 136.
- the cross-sectional shape of the mist current can thus be controlled in a simple manner from the control 86 via the feed current of the electromagnet 130.
