Definitions

  • a stream is understood to mean a mixture of liquid, if appropriate, with suspended solids and / or solids.
  • such a mixture is also referred to as a liquid for the sake of simplification, since the liquid is the main component of the substance flow in question, whereby the presence of suspended matter and / or solids in the mixture designated as liquid is not excluded.
  • the invention relates in particular to fixed, usually buried or under a traffic surface located flow tanks or containers such as. Silos, tanks or earth tanks of a separator device.
  • Such containers in particular for the treatment of problem or dirty water, in which in particular liquids, solids or suspended solids are separated from the liquid or wastewater, must be freed from time to time by the accumulated in the container said substances, which usually about an opening or a manhole is made at the top of the container.
  • the level of the liquid present in the container during normal operation is determined by a predetermined drainage level of the container.
  • the effluent from the container drained liquid can run to a collection system for supply to a wastewater treatment plant.
  • the drain level in the tank is offset at a safe distance from the tank opening.
  • the container opening of the separator tank is located significantly below, for example, a trafficable traffic area, e.g. up to several meters.
  • a trafficable traffic area e.g. up to several meters.
  • a space for access is provided from above to the container opening.
  • a so-called chess neck is created for example by successive rings.
  • the free space in the shaft neck is to be separated from the surrounding earth.
  • the end cap is laid on top of the chute neck.
  • the object of the present invention is to provide a separator system in which a separator container is secured against undesired entry of a foreign substance.
  • a separator container is secured against undesired entry of a foreign substance.
  • the invention is based on a separator system comprising a separator container with a container opening at the top in the separator container, which is above a liquid level in the separator container which settles when liquid flows into the separator container via a feed during normal operation of the separator container and out of the separator container via a drain flows away, wherein above the container opening, a construction arrangement with a closable construction opening adjoins, so that in a closed philosophicalöffung the assembly separates an area above the separator from surrounding areas and open container opening is accessible from above the container opening.
  • the separator is, for example, a light liquid or sludge and light liquid separator.
  • the essence of the invention is that a device for securing the separator container against unwanted ingress of foreign liquid is provided in the separator through the container opening with a closure device for the container opening, wherein the container opening with the closing device against passage of liquid through the container opening is securable ,
  • the container opening can be improved with respect to critical operating conditions in such a way that undesired ingress of liquid from the assembly arrangement through the container opening into the container can be absolutely reliably avoided. An increase in the liquid level in the container via a corresponding critical or maximum absorption capacity can thus not occur.
  • the closing device is designed as a valve arrangement.
  • a main purpose of the container opening in its present manner is directed to a regular inspection of the container interior by a person and / or a suction or removal of a substance collected in the container from the outside via an access section or the chess neck. These measures remain unimpaired by the closing device or valve arrangement according to the invention.
  • the valve assembly is particularly designed so that it can be removed as needed and / or adjusted to allow the intended use of the container opening, for example, as if no valve assembly available.
  • a three-part basic structure In separator systems and the like, in particular a three-part basic structure is known.
  • the possibly provided with a sludge trap container or separator body itself is usually constructed monolithic and tested by the manufacturer, in particular on tightness of the walls and mechanical stability.
  • at least one connection or mounting part can be present, for example an annular component which is reliably sealed with seals to the adjacent container body and which also remains permanently tight, since it is not exposed to any critical mechanical stresses in the installed state.
  • a chess neck with equalizing rings or shaft-forming rings is provided in almost all cases up to a surface or traffic area.
  • the separator container comprises a connection or construction part or manhole.
  • the shaft closure may, for example, comprise a manhole cover which fits onto an opening in the traffic area closing off at the top.
  • the chute neck is due to the height to be bridged or the external loads from the critical part in terms of system leaks.
  • the near-surface area of the compensating rings with the manhole cover can be affected by eg traffic and frost effect, etc. gets leaky with time. Even with unaffected manhole, it is not possible that, for example, in strongly rising surface water or flood the manhole cover or the area of the compensating rings is absolutely tight.
  • liquid entering the chute neck can enter the container via the container opening and thus extraneous water can lead to an increase in the liquid in the container or separator with the problems explained above.
  • valve arrangement With a valve arrangement according to the invention these problems are prevented.
  • the system components can be designed as before and modified accordingly or advantageously existing systems can also be retrofitted on site with a valve arrangement according to the invention.
  • a corresponding sludge trap or separator system including body parts can thus be legal or e.g. Fully comply with DIN specifications.
  • the container or the entire arrangement can be absolutely sure, especially in flood, heavy rain or flood situations against leakage of critical substances from the container into the environment to be protected if the container also has an inlet and backstop.
  • the valve arrangement can be realized from the basic structure in many different configurations, for example automatically as a shut-off valve or as a safety valve. Particularly simple and robust, a flap valve can be used.
  • the closing device is designed such that in the case of liquid protruding above the container opening outside the container, the closing device automatically blocks the passage of liquid through the container opening.
  • a self-closing valve such as a particularly simple and robust flapper valve
  • passage for liquid from the throat into the container can be prevented at precisely the time critical situations occur.
  • the valve assembly may be in a different switching state. It is thereby achieved that the valve arrangement then closes when extraneous water penetrates into the shaft neck. It is not excluded that the valve assembly is designed so that it already closes safely in time, before extraneous water is present at this. The foreign water kept away from the container interior can accumulate above the valve arrangement in the shaft neck.
  • the closing device is designed to allow a gas exchange between the interior of the container and the area above the container when no liquid is present outside the container above the container opening.
  • a gas exchange or air exchange can be ensured at least from the interior of the container to the outside.
  • This is advantageous with regard to a critical gas composition in the container region above the drainage level or a possible danger of explosion due to a corresponding air-gas mixture in the container above the liquid level.
  • the floating light liquid such. Pass gasoline through its comparatively low vapor pressure in such quantities in the overlying gas phase and mix with existing air oxygen that an explosive gas-air mixture is present.
  • valve arrangement can be designed so that the gas or gas-air mixture can escaped outwards into the throat.
  • provision must be made that e.g. When opening the manhole cover a ventilation of the manhole takes place in order to exclude an explosion there.
  • valve arrangement comprises a valve seat arranged in a positionally fixed manner and a movable valve body cooperating with the valve seat, wherein the valve seat comprises a flat material angled in cross-section.
  • valve seat is designed as a mechanically robust and easy-to-mount angled flat material, for example as a continuous circumferential round or polygonal profile steel frame, for example in section angular, T or U-shaped, each with a free leg directed upwards forms the actual valve seat, which cooperates with the valve body.
  • both free legs may form the valve seat, for example, oriented upwardly for providing two sealing lines.
  • the valve arrangement has a valve body designed to be movable against a valve seat, wherein in the closed valve arrangement, if there is no liquid outside of the separator tank above the closing device, the valve body on the valve seat is tight only by the weight of the valve body and gas exchange is possible by the valve body can lift off the valve seat.
  • the valve assembly can be made simple and robust.
  • the container opening can be opened at any time or immediately without further measures or aids by a person, in particular by hand, for example in the case of an inspection of the separator system.
  • the valve body is advantageously particularly simple. In particular, since the valve body is present in a harsh environment in the manhole area and z. B. is exposed to changing temperatures and / or humidity or is subject to corrosion. A simply designed valve body is therefore a prerequisite for its optimal functioning. It is particularly advantageous if the valve assembly or the valve body is formed without additional elements such as closing means or spring means for applying an additional closing force.
  • valve body is lid-like, on which a sealing portion of a sealing material is present, which comes to provide a sealing effect with the valve seat in abutment.
