Definitions

  • the invention relates to a road or floor inlet with retention device for light liquids.
  • light liquids here all liquids or flowable materials are considered, whose density is less than the density of water, such as gasoline, diesel fuel, fuel oil, engine oil and grease.
  • a device for retaining such light liquids from contaminated wastewater is, for example, in DE 31 24 556 A1 described.
  • the retaining device designated there as a filter should have a container through which the wastewater flows, which contains a coalescing and optionally adsorbing immersed filter filling.
  • Such a cleaning device includes a coalescing filter and a gravity separator, these two components of the device each having different functions.
  • the gravitational separator must deposit the majority of the light liquid present in the wastewater by floating.
  • the separated light liquid must be removed continuously or from time to time from the separator. With discontinuous extraction, the storage capacity of the separator must be sufficiently large.
  • the downstream of the separator filter is used to eliminate the residual contamination still contained in the water, ie those portions of the light liquid, which have too small droplet size and thus low buoyancy to be deposited during the residence in the separator.
  • the separation of these residual components takes place by interaction with the surface of the filter filling. As a rule, this consists of a material adsorbing on the light liquid and often also absorbing. But also filters with only coalescing acting, ie the aggregation ofcht crampkeitsteilchen favoring larger droplets filter filling are known.
  • a filter is described with coalescing acting filter filling, in which a device is provided which allows the formation and maintenance of a liquid surface collecting light liquid layer of greater thickness, which is traversed by the wastewater to be cleaned, characterized in that the inlet for the cleaning effluent over the filter filling and in the uppermost area or above the light liquid layer, and that on the downstream side a device is provided which blocks the process when the permissible thickness of the light liquid layer is exceeded.
  • This additional device that blocks the process when the permissible thickness of the light liquid is exceeded.
  • This additional device is housed in a drain chamber, which is separated from the filter filling by a reaching to the lower limit of the light liquid layer baffle.
  • This device for blocking the process is designed as a known from gravity separators ago float valve whose float is tared to the density difference between the light liquid and the wastewater.
  • the light liquid layer is at the top of the filter filling, the thickness of which increases by the ascending through coalescence and buoyancy light liquids until it reaches light thickness under the lower edge of the baffle into the drain chamber on reaching the critical thickness. There it causes the swimmer to shut off the process.
  • a clip assembly for securing the parts of the discharge manifold in their relative position to each other is further provided.
  • a waste water inlet for streets, courtyards or the like is known with a frame supported by a grate, a arranged under the lattice leaf retention basin and a drain provided with collecting container.
  • Sewer water inlets of this type are known, inter alia, under the name "gully”.
  • Such enemas are, for example, in the street gutter and at the low points of surfaces to be drained and serve to drain the dirty water into the sewer.
  • the sump is divided by a liftable partition bottom into an upper settling chamber and a lower collecting chamber and valve chamber.
  • the settling chamber is connected to the collecting chamber via a downpipe whose inlet opening is located at a greater distance from the separating bottom and whose outlet opening is below the outlet.
  • a settling chamber is to be created below the leaves retention basin and above the valve chamber and a collection chamber in which the sludge located in the wastewater can settle.
  • a passage of the polluted with light liquid wastewater through the existing water reservoir is ensured, as it is in the DE 31 24 556 A1 is indicated as advantageous.
  • the DE 34 03 718 A1 describes a light liquid separator with a substantially horizontal flow through the settling chamber.
  • a deposition effect is achieved here by the design of an inlet manifold with a network device for reducing the inlet velocity and a downcomer.
  • a separating device for the separation of flammable liquids from the sewer is out FR 680 827 known, among other things, includes a spout with a multiple siphon.
  • a light liquid separator with calming walls and a drain which can be closed with a floating body is known from the German patent specification 485 119 known.
  • a road or floor inlet with a retaining means for light liquids known comprising at least one inlet, a collection chamber, at least one valve chamber, and at least one outlet, said at least one outlet having a substantially upwardly directed valve-closable drain inlet directly or via a sealing element forms an approximately horizontal sealing seat which is tightly closed by a designed as a closing body for the valve float, wherein the float has a specific gravity between 0.72 g / cm 3 and 1 g / cm 3 and the manifold below the drain inlet is provided with a ventilation.
  • the invention has for its object to further improve a waste water inlet of the type described above with regard to its reliability and lower maintenance requirements, in particular with regard to a simplification of the maintenance work to be performed.
  • a road or bottom inlet with a retention device for Leichmatikeiten comprising at least one inlet, at least one collecting chamber, at least one filter chamber, at least one valve chamber and at least one outlet; wherein the at least one drain has a substantially in installation position of the road or bottom inlet upwardly, closed by a valve drain inlet which forms a sealing element in an installed position of the road or bottom inlet almost horizontal sealing seat directly or via a sealing element; wherein the sealing seat is tightly closed by a designed as a closing body for the valve float; characterized in that the inlet has a first fluid connection to the collection chamber, that the collection chamber has a second fluid connection to the filter chamber, that the filter chamber has a third fluid connection to the valve chamber, wherein the second fluid connection comprises a coarse filter and wherein the third fluid connection includes a fine filter.
  • the arrangement according to the invention of coarse filter and fine filter has the advantage that coarser and in particular flat particles are kept away from the fine filter and thus the fine filter is not clogged so quickly, whereby the cleaning or replacement interval can be increased. Since the coarse filter is located in the second fluid connection between the collection chamber and the filter chamber and there is easy access from the outside to the collection chamber, the coarse filter can be easily cleaned from the outside than the fine filter. Furthermore, the arrangement has the advantage that the fine filter is not damaged by larger objects in the wastewater, as they are filtered out by the coarse filter.
  • the flow-through cross-section of the coarse filter in the second fluid connection is greater than the flow-through cross section of the third fluid connection. This prevents a suction effect from the collecting chamber in the filter chamber. This means that the coarse filter has a greater permeability than the fine filter.
  • the flow-through cross-section of the third fluid connection is greater than the flow-through cross section of the sequence.
  • the passage openings of the coarse filter are designed so that the passage of a spherical test specimen with a diameter of 15 mm is prevented.
  • the passage openings of the coarse filter are formed so that the passage of a spherical test body is prevented with a diameter of 13 mm and more preferably the passage of a test specimen with a diameter of 10 mm. This ensures that the coarse filter can filter out smaller and larger branches, paper waste and cigarette butts from the wastewater, so that the risk of clogging or damage of the fine filter is minimized.
  • the lower end of the fine filter in the installed position of the road or bottom inlet is spaced from the bottom of the road or bottom inlet in the installation position of the road or bottom inlet. This will ensure that yourself Dirt particles contained in the wastewater can settle at the bottom of the filter chamber without polluting the fine filter.
  • the distance is less than 15 cm, more preferably less than 10 cm, and most preferably about 7 cm.
  • the collecting chamber may expediently have a fluid opening to the filter chamber, wherein the fluid opening is arranged at the bottom of the road or bottom inlet in the installation position and has a maximum height which is not greater than the distance of the lower end of the fine filter from the bottom of the road or bottom run.

  • the additional settling chamber has the advantage of being in the wastewater containing dirt particles that settle in a stagnant water at the bottom, do not settle in the collection chamber and / or filter chamber, but separately in the settling chamber.
  • the arrangement of the settling chamber above the collecting chamber allows easy cleaning of the settling chamber.
  • the dividing floor extends over the entire horizontal cross-section of the road or floor inlet in the installation position of the road or floor inlet.
  • the dividing bottom expediently has an overflow pipe.
  • the filter chamber and / or valve chamber of the partition bottom is advantageously formed in two parts, with a part of the road or floor inlet is removable.
  • the removable part of the separating tray is concentrically surrounded by the other part of the separating tray.
  • the removable part of the partition floor to the other part of the partition floor, so that the two parts can not move relative to each other in the connected state.
  • wastewater could pass directly into the collection chamber, the filter chamber and / or valve chamber without first passing through the second, third or fifth fluid connection and thus bypassing the coarse and / or fine filter.
  • the two parts of the separating bottom are releasably connected to each other by means of at least one pivotable bolt.
  • the use of two Vorreibern has proven to be particularly practical, since they can be pivoted by means of a rod and the operator does not need to bend over.
  • the removable part of the dividing floor has an eyelet, so that the removable part of the dividing floor can be easily lifted out of the road or floor inlet by means of a hook or the like.
  • the removable part of the separating tray and / or the other part of the separating tray have means which fix the position of the two separating tray parts to one another. This ensures that the fifth fluid connection arranged on the separating tray is always correctly positioned, so that it connects the settling chamber to the collecting chamber and, for example, not the settling chamber with the filter chamber or valve chamber.

  • This floating and closing body 10 is slightly lighter (0.9 - 9.98 kg / dm 3 , preferably by 0.97 kg / dm 3 ) than the water displaced by it, so that he, like the FIG. 3 shows, floats in the water and thus at a correspondingly high level of water 23, the drain inlet 8 opens. If the floating body 10 is surrounded by a liquid which has a lower density than the floating body 10, for example gasoline with a density of 0.72 g / cm 3 , this floating body 10 sinks into the liquid and thus closes the drainage inlet 8.
