Definitions

the invention relates to an extinguishing device with a container in which an extinguishing agent is received, wherein an elastic expansion body is provided which is stretchable with a blowing agent, so that the extinguishing agent can be expelled from the container via a change in shape of the expansion body.
a quenching device is known with a container, wherein a part of the container is provided for a propellant, and wherein a further part of the container is provided for receiving an extinguishing agent.
the parts of the container are separated by an elastic membrane, and when a blocking element is opened, the extinguishing agent can be carried out of a nozzle by a pressure in the propellant through the elastic membrane.
the propellant for pressure build-up occupies a large part of the container volume.
the DE 298 18 066 U1 shows an erasing device with a container in which an expansion body is inserted, which separates a receiving area for an extinguishing agent from a receiving area for a propellant.
the blowing agent outside the expansion body surrounds the extinguishing agent within the expansion body, and the blowing agent can be pressurized via an external compressed air supply.
the propellant occupies a large volume fraction of the total volume of the container.
an extinguishing device with a container is shown, and in a first variant ( FIG. 1 ) an elastic expansion body is shown, in which a propellant is receivable.
An extinguishing agent is received between the elastic expansion body and the container, and when the expansion body is pressurized with the propellant, the expansion body expands, and that existing outside of the expansion body Extinguishing agent can be transported out of the container.
the means for applying a pressure to the propellant are located outside the container, and the pressurization can be controlled via a valve on the container.
the entire arrangement for pressurizing the propellant is outside the container.
the invention includes the technical teaching that in the container a propellant cartridge is added to release the propellant, which is coated with the expansion body, and wherein the extinguishing agent is received in the space between the expansion body and the container.
the extinguishing device allows a compact construction with a container in which both the means for generating pressure, the blowing agent and the extinguishing agent are added.
the propellant may be pressurized in the container without permanently keeping the extinguishing agent under pressure. Only when the propellant cartridge is activated can the propellant escape from the propellant cartridge and fill the elastic expansion body from the inside. By the occurrence of the propellant in the elastic expansion body, this expands, and can drive out the extinguishing agent from the container by his thus entering shape change.
the expansion body By arranging the propellant cartridge in the expansion body, the expansion body can envelop the propellant cartridge, and upon activation of the propellant cartridge increases the volume of the expansion body, which increases the volume reduced between the expansion body and the container, and so that the extinguishing agent exits the container.
the extinguishing device has a connection head through which the extinguishing agent emerges from the container, wherein the propellant cartridge is arranged on the connection head and preferably projects freely into the container.
the connection head can be arranged detachably on the container, and when the connection head is released, the propellant cartridge can in particular be exchanged together with the elastic expansion body on the connection head.
the connection head can be screwed into the container.
the expansion body in the non-activated state of the propellant cartridge may substantially have the shape of the propellant cartridge and preferably at least partially abut the propellant cartridge.
the structural unit ofkulturschpatrone and expansion body takes only a small volume in the container. Only when the propellant cartridge is activated does the propellant escape from the cartridge and fills the radial gap between the propellant cartridge and the elastic expansion body. As a result of the entering of the propellant between the propellant cartridge and the expansion body, the expansion body expands and reduces the volume of the extinguishing agent in the container so that it can escape from the connection head.
the expansion body can be formed by a bladder made of an elastic material, preferably of a rubber material, which is arranged with an opening on the connection head.
the expansion body encloses the propellant cartridge such that it is inserted substantially completely into the opening of the expansion body and the opening of the expansion body encloses the connection part of the propellant cartridge on the connection head.
the propellant cartridge is activated, the propellant taken up in the propellant cartridge can flow completely into the expansion body.
the expansion body with the opening is pressure-tightly arranged on the connection head.
the expansion body may have a wall thickness with increasing distance from the opening is designed decreasing. By a smaller wall thickness, the compliance of the expansion body can be reduced. If the blowing agent from the propellant cartridge flows into the elastic expansion body, the deformation of the expansion body begins in the region in which the expansion body has the smallest wall thickness. If the expansion body has the smallest wall thickness at its free end, which is located opposite the end with the opening of the expansion body in arrangement at the connection head of the extinguishing device, then the expansion body expands first in the rear region of the container. The discharge of the extinguishing agent from the container also takes place via the connection head, and the extinguishing agent is pressurized starting from the rear region of the container.
a mandrel may be provided which protrudes into the container. If the expansion body has reached a volume from the propellant cartridge by the flow of the propellant, which volume has substantially completely expelled the extinguishing agent from the container, the expansion body can come into contact with the mandrel so that the mandrel causes the expansion body to burst. It can thereby be achieved that, after the extinguishing agent has exited, the propellant can additionally escape from the container in order to depressurize the container after use of the extinguishing device.
the unpressurized state of the container after use of the extinguishing device facilitates the opening of the container, for example by unscrewing the connection head.
propellant cartridge and expansion body be removed from the container more easily.
the mandrel is arranged on the connection head.
the propellant cartridge can form a structural unit with the expansion body, which is arranged interchangeable inside the container on the connection head.
the connection head can be removed from the container, in particular be unscrewed from this, wherein the propellant cartridge and the expansion body are also arranged detachably on the connection head.
the propellant cartridge can be screwed on the inside of the connection head, wherein furthermore the expansion body can have a ring element, through which the opening of the expansion body is formed, and with the ring element of the expansion body is also screwed to the connection head.
the ring element encloses the propellant cartridge completely.
the container has a much larger volume than the propellant cartridge.
the propellant cartridge takes in the container only a small proportion of the total volume of the container.
the container may have a volume between 10 liters and 50 liters, wherein in particular the propellant cartridge may have a volume of 0.3 to 1.5 liters.
the volume of the container may be about 30 times the volume of the propellant cartridge.
the propellant cartridge may form a metal bottle that is pressurized with the propellant. When the propellant cartridge is activated, the expansion of the propellant issuing from the propellant cartridge is sufficient to drive the extinguishing agent substantially completely out of the container.
the extinguishing device may be designed for a stationary installation, wherein a supply port and a removal port are provided on the connection head.
a piston can be activated pneumatically, which pierces the LPG cartridge with a thorn.
the piston can be pneumatically activated in the connection head of the extinguishing device, for example, in which nitrogen, CO 2 or compressed air is supplied through the supply port, preferably at a pressure of 2 bar.
nitrogen, CO 2 or compressed air is supplied through the supply port, preferably at a pressure of 2 bar.
the piston is moved with the mandrel in the direction of the propellant cartridge, and the mandrel can pierce the propellant cartridge, so that the propellant from the Propellant cartridge can flow out.
the pressurization of the extinguishing agent this can escape through the removal connection from the connection head and thus from the container.
a pipeline can be arranged in order to guide the extinguishing agent to a fire source.
connection head can be designed as a manually operable erase head, so that the extinguishing device forms a hand-held extinguisher.
the inventive design of the extinguishing device with a propellant cartridge inside the container and the expansion body, which surrounds the propellant cartridge, the extinguishing device can be operated in any position without a fire extinguisher must preferably be operated in a specific location.
FIG. 1 shows an embodiment of an erasing apparatus 100 having the features of the present invention.
the extinguishing device 100 is shown in a cross-sectional view, and has a container 10, which preferably extends rotationally symmetrically about a central axis 20.
the container 10 may be formed of a metal body, and for sealing the container 10 is a connection head 15th
an extinguishing agent 11 is added, which may be powdery, liquid or even gaseous.
the extinguishing agent 11 When the extinguishing agent 11 is pressurized, it can escape from the container 10 through a removal connection 19 on the connection head 15.
FIG. 1 shows the propellant cartridge 14 in a non-activated state so that the propellant 13 is completely within the propellant cartridge 14.
the propellant cartridge 14 is enveloped with an elastic expansion body 12, and the elastic expansion body 12 is in a non-pressurized state, so that the expansion body 12, the propellant cartridge 14 is wrapped and about this rests.
a piston 21 can be activated, on which a mandrel 22 is located.
the activation of the piston 21 can be effected by a pneumatic pressurization through a supply port 18 in the connection head 15.
a pneumatic pressurization of the piston 21 it is moved with the mandrel 22 against the propellant cartridge 14, so that the mandrel 22, the propellant cartridge 14 pierces, and so that the propellant 13 from the propellant cartridge 14 exit and can enter the expansion body 12.
FIG. 2 shows the extinguishing device 100 in an activated state of the propellant cartridge 14.
the piston 21 has been pneumatically activated, so that the mandrel 22 has the propellant cartridge 14 pierced.
blowing agent 13 can enter the expansion body 12 from the propellant cartridge 14.
the expansion body 12 has a wall thickness, which is performed with increasing distance from the opening 16 of the expansion body 12 decreasing.
the wall thickness of the expansion body 12 at its end the smallest thickness, so that a change in shape of the expansion body 12 at the opening 16 far end begins, shown as the end bladder in the expansion body 12.
the extinguishing agent 11 located in the container 10 can then through the extraction port 19 in the connection head 15 escape from the container 10. With increasingly leaking propellant 13 from the propellant cartridge 14 in the expansion body 12 into this expands further until the material of the expansion body 12 inside reaches against the wall of the container 10, see FIG. 3 ,
FIG. 3 shows the extinguishing device 100, after a majority of the propellant 13 has leaked from the propellant cartridge 14 and flowed into the expansion body 12 or flowed.
the expansion body 12 is substantially completely against the inside of the container 12, and a large part of the extinguishing agent 11 has already left the container 10 through the extraction connection 19.
FIG. 4 shows the extinguishing device 100 in an end stage after activation of the propellant cartridge 14, in which substantially the propellant 13 has completely flowed into the expansion body 12, and this has substantially completely extinguished the extinguishing agent 11 out of the container.
a mandrel 17 is arranged, against which the expansion body 12 passes, so that the mandrel 17, the expansion body 12 in a bursting area 23 aufsticht. It can thereby be effected that after the extinguishing agent 11 has flowed out of the container 10, the propellant 13 can subsequently emerge from the expansion body 12 and leave the container 10 through the removal connection 19.
the expansion body 12 can be depressurized after exiting the extinguishing agent 11, for example, to remove the propellant cartridge 14 with the expansion body 12 by a removal of the connection head 15 from the container 10 also from this.
the extinguishing device 100 shown may be designed for a stationary installation, wherein the pressurization of the piston 21 by compressed air, by CO 2 or by nitrogen can take place. Of course, any further form of activation of the propellant cartridge 14 is conceivable.
the connection head 15 of the extinguishing device 19 can be manually operated in a manner not shown in detail, so that the extinguishing device 100 is designed as a hand-held extinguisher.
