Definitions

• the invention relates to a device for odor-free ventilation of closed liquid containers, in particular of waste water containers.
• odor-free venting of such containers is necessary, for example, if the containers are used for the disposal of sanitary facilities.
• the container air is under a slight excess pressure, which must be compensated for by a venting device.
• the problem of eliminating odors is usually associated with venting the container. In particular, if the container is set up as a waste water container in an apartment, measures for odor-free ventilation are required.
• f_.rsatzb.att for ventilation mostly through the basement ceiling and other living rooms to a ventilation pipe. Odor-free ventilation becomes even more complex if, as in many old buildings, a ventilation riser pipe is not available. Then the pipeline from the waste water tank to the roof of the house is to be run.
• the invention has for its object to provide a device for odor-free ventilation of closed ' liquid containers, which can be used technically simple and inexpensive in connection with closed liquid containers and in particular an additional pipeline to a ventilation pipe or even from the installation site to the roof surface makes redundant.
• the device is formed by a rotationally symmetrical bezel which is open on both sides and through which the upper region of the container interior is connected to the external environment, an air filter arranged in the bezel and an automatically operating liquid shut-off valve .
• the device according to the invention ensures that container air flows into the immediate outer '
• Ers keitssperrventi 1 is arranged in the enclosure used for ventilation. When liquid enters the enclosure, this valve blocks the connection between the interior of the container and the outside environment in good time before the liquid can escape.
• the air filter consists of a multilayered plastic sheet with activated carbon layers.
• the device according to the invention is expediently arranged in the lid of the liquid container.
• the technically simplest construction is given by the fact that the casing is aligned vertically and the air filter is arranged in the lower area and the liquid shut-off valve in the upper area of the casing. Because of this arrangement, both a conveniently dimensioned air filter and a liquid shut-off valve can be integrated into the enclosure with simple means.
• the border is essentially cylindrical with a constriction of rotation symmetry at its upper end and a floating closure body, arranged as a liquid shut-off valve between the air filter and the constriction, which in the normal state rests on the air filter. so that air can escape through the device to the outside.
• the floatable closure body and the air filter can easily be inserted and, if necessary, exchanged in the rim, which is thus formed in an ash-like shape.
• Replacement Closure body must of course have a suitable shape corresponding to the inside of the constriction to form a liquid shut-off valve, so that in the locked state it lies tightly against the inside of the constriction.
• it must be dimensioned such that it can move between the air filter and the constriction and, in the normal state, allows air to pass through the constriction when placed on the air filter.
• a table tennis ball is inexpensive as a closure body. Therefore, in one embodiment of the invention, a tennis ball is used as the spherical closure body.
• the device according to the invention can be inserted into a suitable opening in the container lid or in the container wall.
• the device is expediently provided with a fastening flange which is integrally formed on the outward-facing end of the casing, and with fastening elements for sealingly connecting the fastening with the edge of the container opening in which the device is provided.
• the fasteners can, for example, consist of screws, clamps and, if necessary, additional seals.
• the border can also be integrally formed on the container lid or the container wall. This is particularly useful if the
• Container or the container lid as one piece Part can be made so that the device according to the invention can be easily integrated therein.
• Fig. 2 shows a section through an embodiment integrated in a waste water disposal device.
• Fig. 1 The embodiment shown in Fig. 1 is for vertical insertion in a suitable opening in the
• Cover or provided in a horizontal, upper wall area of a liquid container. It consists essentially of a rotationally symmetrical border 1 with a f1 ash-necked constriction 2 at its outward-facing end, an air filter 3 arranged in the lower region of the border 1, a floating closure body arranged between the air filter 3 and the constriction 2 ⁇ by 4 and a fastening flange 5 integrally molded onto the outward-facing end of the casing 1 with fastening elements 6.
• the border 1 is formed with the exception of the upper constriction 2 substantially cylindrical, but with a slight conical widening downwards.
• the air filter 3 consists of several foam layers 7 with activated carbon layers 8 interposed therebetween. The air entering the device from below under slight pressure penetrates the foam layers 7 at a moderate speed
• the floatable missile body 4 is spherical and dimensioned such that it has sufficient horizontal and vertical play relative to the inside of the casing 1. In the normal state, it rests on the air filter 3, as shown by the solid circle in FIG. 1. If liquid rises from the container into the area of the closure body 4, it floats and reliably seals the device against leakage of liquid in the position shown by the broken circle in FIG. 1.
• the fastening flange 5 is tightly connected by means of screw connections as fastening elements 6 to the edge 9 of the container opening into which the device is inserted.
• the flange 5 is provided on its edge region with through openings 10 arranged symmetrically to one another for the passage of screws 11.
• through openings 12 with an internal thread are provided in the edge 9 of the container opening, in which the screws 11 can be fastened.
• Fig. 2 shows another embodiment in which the border 13 of the device is integrally molded onto the container lid 14 of a wastewater disposal device 15.
• the container lid 14 is produced as a closed, hollow plastic part, for example as a rotary casting, into which other elements of the waste water supply device are integrated in addition to the device for odor-free ventilation.
• two inlets are drawn through which the waste water disposal device is fed with waste water.
• the upper inlet for example a wash basin inlet, leads via an immersion pipe 16 through the upper wall part of the container lid into an in Bottom molded bottle siphon 17.
• the bottle siphon 17 serves as a liquid reservoir and, in conjunction with the immersion tube 16, forms an odor trap for the wash basin supply.
• An overflow 18 is arranged next to the bottle siphon 17, through which the washbasin waste water from the container lid 14 enters the container 19.
• the lower inlet 20 is intended for example for waste water from a shower tray.
• the wastewater accumulating in the container 19 is pumped out with the aid of a submersible pump 21 via a pressure line 22 and fed into the sewage system.
• the bad air collecting in the container 19, which is under a slight excess pressure, is freed from the smell by the device integrated in the container lid 14 and released into the environment.
• the lid base is shaped as a double-walled sleeve 23, which extends to the inside of the container, the sleeve wall having an elongated, U-shaped profile and the inner wall of the sleeve 23 forming a faschal neck-shaped opening on the upper lid wall is molded.
• the enclosure 13 formed by the inner wall of the sleeve 23 has the same shape as the enclosure 1 of the above exemplary embodiment intended for insertion into a container opening.
• the arrangement and design of the air filter 3 and the schwiramf higen closure body 4 corresponds to the gameconsbei above.
• the closure body 4 and the air filter 3 can easily be inserted into the frame and, if necessary, replaced.
• the separate device is detached from the container opening and removed from the container, while in the second embodiment, the container lid 14
• Spare sheet is removed from the container 19 with the device integrated therein.
• the device represents a considerable technical simplification compared to the previously known devices for odorless venting of liquid containers and, in particular, makes an additional pipeline from the container to a vent pipe or even to the roof surface superfluous.
