Oil sealant-preserving drain odor trap

In an odor trap apparatus for conveyance of wastewater to an external drain, comprising (a) a container having an opening entry for receiving the wastewater therein, (b) a baffle in said container dividing said container into an entry compartment into which the wastewater is received through said opening entry and a discharge compartment communicating with and defining therewith a liquid flow path passing above and beneath said baffle, (c) an outlet communicating said discharge compartment with the external drain, and (d) a quantity of low-density liquid in said entry compartment forming a sealant layer above the wastewater in said entry compartment, the improvement in which:

• said baffle extends a generally extending horizontal distance, measured from said opening entry to an end of said baffle, around which the wastewater passes;
• and
• the distance is sufficiently large as to permit the wastewater to pass substantially fully through the sealant neighboring said baffle end.

• said baffle extends a generally extending horizontal distance, measured from said opening entry to an end of said baffle, around which the wastewater passes;
• the distance is sufficiently large as to at least minimize turbulence in said sealant layer adjacent said baffle end, and
• an inlet cover incorporating said opening entry and a shelter region formed between said baffle and said inlet cover adjacent said baffle end, and at least one air vent in said inlet cover for allowing air within said shelter region to vent outside thereof and thereby for lessening the effects of any high pressure of the wastewater from deleteriously affecting said sealant layer.

In an odor trap apparatus for conveyance of wastewater to an external drain, comprising (a) a container having an opening entry for receiving the wastewater therein, (b) a baffle in the container dividing the container into an entry compartment into which the wastewater is received through the opening entry and a discharge compartment communicating with and defining therewith a wastewater fluid flow path in the compartments which passes above and beneath the baffle and about an end thereof, (c) an outlet communicating the discharge compartment with the external drain, and (d) a quantity of low-density liquid in the entry compartment forming a sealant layer above the wastewater in the entry compartment, a method for conserving the quantity of the liquid, comprising the steps of:

• disposing a portion of the baffle under the sealant layer, for a distance between the opening entry to the baffle end which is sufficient to permit the wastewater to pass through the sealant layer and at least to minimize turbulence in the sealant layer from the wastewater neighboring the baffle end.

In an odor trap apparatus for conveyance of wastewater from an entry to an external drain along a flow path that passes through a quantity of liquid odor sealant floating on the wastewater, a method for conserving the quantity of the liquid, comprising the steps of:

• disposing a baffle under the sealant for lengthening the flow path above and beneath the baffle and about an end thereof;
• and
• extending the baffle, for a distance between the entry to the baffle end, sufficient to minimize turbulence in the sealant from the wastewater neighboring the baffle end.

In an odor trap, which is adapted for placement in and removal from drain connected apparatus, including waterless urinals and anti- evaporation floor drains, and for conducting wastewater to an external drain, and which includes (a) a container having a top cover provided with an opening entry portion therein for receipt of the wastewater and for conducting the wastewater through a flow path which includes a quantity of low-density liquid adapted to form a sealant layer, and to the external drain, and (b) the opening entry including a plurality of openings through which the wastewater passes into the container, a method for inserting and removing the container into and from the apparatus comprising the steps of:

• utilizing a tool having hook-shaped projections therein;
• and
• engaging the projections into the openings.
