Definitions
- the invention relates to a spray device for liquid or powdery substances, in particular fire extinguishing and protective agents, consisting of a substance container, from which a riser leading to a spray head emerges, and a compressed gaseous medium containing pressure container, which communicates with the reservoir via a Shut-off valve is in line connection, the spray head being composed of a lower part, which preferably widens in the shape of a goblet, coaxially adjoining the riser line, and a lid-shaped upper part which can be sealingly placed thereon, and which can be lifted off the lower part up to a height-adjustable stop against weight and / or spring loading guided upper part between itself and the lower part by expelling the substance due to a preferably sensor-controlled automatic actuation of the shut-off valve between the pressure vessel and the reservoir opens an annular gap.
- These spray devices which are mainly used as fire extinguishers, are activated by opening the connection line between the pressure tank and the storage tank, since then the compressed medium, e.g. compressed air, can flow into the storage tank and push the substance filled in there through the riser pipe to the spray head, depending on which of the application pressure, the spray head shape and. The like. is sprayed.
- the compressed medium e.g. compressed air
- the spray head depending on which of the application pressure, the spray head shape and. The like. is sprayed.
- the upper part of these spray heads is, however, guided centrally via a single spindle or the like and anchored in the lower part, so that, with the slightest irregularities in the exiting stream of extinguishing agent and the like.
- the upper part immediately tilts, which affects the annular gap and disrupts the all-round spray jet. It is therefore important to ensure that the upper part is guided as precisely as possible, which in turn greatly reduces the functional reliability of the spray head, since corrosion, dirt, etc. prevent the required mobility of the upper part after a short time.
- the area of application of these known spray heads remains very limited due to the need to always spray the substance in a fully all-round jet. A coverage of this jet in some areas is impossible here, because a one-sided jet would tip the upper part and cancel the nozzle effect of the annular gap.
- the invention is therefore based on the object to remedy these shortcomings and to provide a spraying device of the type described which is characterized by particular functionality and operational reliability, allows the generation of a fan or spray jet adapted to the respective spatial conditions and is achievable on the basis of the achievable Substance distribution brings an optimal extinguishing effect.
- the invention solves this problem in that the spray head as a guide and stop for the upper part in the radially outside of the seat between the upper and lower part, preferably widened edge strips parallel to the spray head axis, has regularly distributed screw bolts with nuts or the like. These, for example, welded in the lower part, with their free end protruding through matching holes in the upper part, provide the most straightforward way of safely guiding the lifting movement of the upper part, and the nuts are precise and easily adjustable stops outside the final seat ensure that the tightness of this closure is not interrupted or impaired when the upper part is seated on the lower part.
- the spray head results in a self-regulating distribution of the substance conveyed through the riser, which lifts the upper part and opens the previously closed annular gap between the upper and lower part completely evenly.
- the spray head or its upper part provides a simple, tight seal for the container, and the circumferential multiple guidance of the upper part permits the play clearance of the upper part movement that is necessary for a real, operational safety without any risk of tipping. Since the substance present in the storage container can be distributed evenly over large areas in a very short time with this spray head, such a spraying device is also particularly suitable for fire fighting and preventive fire fighting.
- shut-off valve between the pressure tank and the storage tank can be actuated automatically, for example by an optical or thermal sensor, an automatic protection and extinguishing system is also created immediately, since opening the shut-off valve causes the substance stored in the storage tank to spray quickly, with the substance requesting an extinguishing or can be a protective agent.
- the entire spraying device is independent of any fixed installation and therefore ready for use anywhere and at any time.
- the spray head can also have an adjustable cover to limit the circumferential gap opening, the cover consisting, for example, of an arcuate rail which is slidably attached to peripheral edge flanges of the upper and lower part .
- the cover consisting, for example, of an arcuate rail which is slidably attached to peripheral edge flanges of the upper and lower part .
- a simple rail can be used as a cover, which can be moved along the edge and delimits the spray area in the desired sense.
- the rail can be made from two or more parts in order to be able to cover or release different angular ranges.
- two supply lines with a different cross-section lead from a common supply line starting from the pressure container and receiving the shut-off valve into the interior of the storage container, of which those with a larger cross-section than the supply line in the ceiling area of the storage container and those with a smaller cross-section than
- the atomization line opens in the area of the riser inlet opening. If the storage container is pressurized to expel the respective substance in the ceiling area, pressure medium is practically blown into the riser at the same time, so that, due to the resulting injector effect, the substance pushed outwards through the riser is swirled with air or gas and an air-substance mixture passes the spray head. This injector effect also leads to an increased conveying speed and thus to a greater range of the spray jet.
- the different dimensioning of the lines can be used for the desired division of the available with little effort Media.
- a further simplification can be achieved by the common supply line, since only a single shut-off valve is required and in any case, when the device is used, the admission line and the atomization line are simultaneously supplied with pressure medium.
- the pressure container and reservoir or pressure medium and substance to be sprayed are to be coordinated with one another in such a way that the range of the spray jet decreases steadily during the spraying of the substance, as a result of which the largest possible area is sprayed with this substance.
- a pressure vessel is connected to the reservoir via a sensor-controlled shut-off valve and this valve opens the connection between the pressure vessel and the reservoir at a suitable moment, a fan-shaped or umbrella-shaped spray jet results, the range of which decreases evenly from an initial maximum width, so that over a corresponding large area the substance is distributed from the storage container, in approximately the same amount per unit area.
- a spraying device is particularly well suited for fire protection, since a protective agent can be sprayed at the time of danger that prevents the fire from progressing.
- the spraying device 1 used as an automatic fire extinguisher consists of a storage container 2 for a fire extinguishing and protective agent, which is equipped with a riser 3 and a spray head 4 placed on the riser.
- Compressed air or another compressed gas from a pressure container 5 is used to drive out the extinguishing and protective agent from the storage container 2, to which two feed lines to the interior of the storage container 2 are connected, of which one is connected via a common supply line 6 and an automatically controlled shut-off valve 7 with a larger cross section than the supply line 8 opens into the ceiling area 9 of the container 2 and the other with a smaller cross section leads as an atomization line 10 into the area of the riser inlet opening 11.
- the atomization line 10 also has 2 additional blow-out openings 13 in the bottom region 12 of the container.
- the spray head 4 is composed of a goblet-shaped widening lower part 14 adjoining the riser 3 and an upper part 15 which can be placed sealingly on this lower part, with a tapering, between the upper part 15 and the lower part 14 a centrally symmetrical distribution and deflection resulting channel 16 is formed. If the storage container is depressurized, the upper part 15 sits tightly on the lower part 14 (dashed line in FIG. 2), on the other hand, if the medium filled in the storage container 2 is expelled by pressurization, the upper part 15 lifts off the lower part 14 and opens an annular gap 17 through which the channel 16 opens approximately horizontally into the open.
- an adjustable stop for the removable upper part 15 is provided, which consists of screw bolts 18 and nuts 19 screwed onto them. These bolts 18 are inserted in the lower part 14 and protrude through openings in the upper part 15, whereby they additionally serve as a vertical guide for the lifting movement of the upper part 15. In order not to cause any leaks for the spray head 4 through these bolts 18, they lie radially outside the seat surfaces 20 of the upper part 15 and lower part 14, this edge strip 21 located outside the seat being widened by the upper and lower part 15, 14, so that the jet sprayed through the annular gap 17 can also pass unhindered.
- a rail 22 is provided as a cover, which is slidably mounted on peripheral edge flanges 23 of the lower and upper part 14, 15.
- This, for example, two-part rail 22 can now be used to cover the angular range which is not to be reached by the sprayed jet, which is necessary, for example, when the sprayer is set up on a wall 24, as indicated in FIG. 3.
- the sprayer 1 is started by the automatic control of the shut-off valve 7, for example depending on the ambient temperature or by actuating a manual valve 25 installed in the supply line 6, the connection between the pressure container 5 and the interior of the storage container 2 opens and compressed air flows through the admission line 8 and the atomizing line 10 both in the ceiling area 9 and in the bottom area 12 of the storage container, whereby the extinguishing and protective agent filled in the storage container 2 is whirled up in the bottom area and pressed up with the possibly existing separated components via the riser 3 to the spray head 4 and simultaneously with it is swirled on the way through the riser and aerated.
- the result is an air-extinguishing agent mixture which is evenly distributed by the spray head 4.
- the atomization achieved causes the extinguishing and protective agent to spread spatially, in order to be able to cover a large area in the radial direction and to be able to spray the agent as widely as possible, by mutually coordinating the pressure and volume of the pressure container 5 and the volume of the storage container 2 therefor can be ensured that the range of the umbrella-shaped beam decreases continuously from an initial maximum size to zero, which can be achieved, for example, if the overpressure in the pressure vessel 5 is greater by the same factor as the external pressure as the volume of the reservoir 2 compared to that of the Pressure tank 5.
- the reservoir 2 and pressure vessel 5 can be arranged one above the other and have a common casing 26, so that the sprayer 1 forms an easy-to-assemble unit, no additional stationary devices being required and due to the problem-free refillability of the reservoir and Pressure tank, frequent use of the sprayer is also possible.
- the spraying device according to the invention is characterized by its ability to be able to distribute large amounts of liquid or powdery substances uniformly over large areas in a short time, for which purpose the corresponding shut-off valve only has to be opened manually or automatically, so that it is particularly suitable for use in fire protection is suitable.
