Separation device for emission reduction in stables and animal stable

A separating device for forming a standing area for livestock and for reducing emissions in pens, the separating device comprising:

• a base frame;
• a drainage element having a plurality of adjacent drainage channels each comprising an outflow end and a plurality of shoulders between which the plurality of drainage channels extends orthogonally to a drainage direction;
• a transverse drainage member, wherein the transverse drainage member acts as a first support for the drainage element;
• and
• a liquid-permeable endless belt with an upper run and a lower run;
• wherein the drainage element if arranged on the base frame such that a drainage direction of the plurality of drainage channels is directed in the direction of the outflow end, and the outflow end is positioned such that a liquid flowing out of the outflow end reaches a transverse drainage channel, and wherein the drainage element is arranged between the upper run and lower run, and the upper run rests on at least a one of the plurality of shoulders, wherein the upper run serves as a standing area for animals.

An animal pen comprising:

• at least one animal holding bay;
• a separating device comprising:
• a base frame;
• a drainage element having a plurality of drainage channels each comprising an outflow end and a plurality of shoulders between which the plurality of drainage channels extends orthogonally to a drainage direction;
• and
• a liquid-permeable endless belt with an upper run and a lower run;
• wherein the drainage element is arranged on the base frame such that a drainage direction of the plurality of drainage channels is directed in the direction of the outflow end, and the outflow end is positioned such that a liquid flowing out of the outflow end reaches a transverse drainage channel, and wherein the drainage element is arranged between the upper run and the lower run, and the upper run rests on at least a one of the plurality of shoulders, wherein the upper run serves as a standing area for animals;
• wherein the separating device is arranged such that a conveying direction of the upper run is directed in the direction of one or more of an inspection aisle, a disposal aisle, or a boundary element and the separating device extends over the entire width of the animal holding bay;
• wherein the animal pen further comprises the inspection aisle and the disposal aisle, and the separating device is arranged such that a conveying direction of the upper run of the liquid-permeable endless belt is directed in the direction of the inspection aisle and the disposal aisle, and a conveying plane of the upper run of the liquid-permeable endless belt is arranged substantially in the same plane as the inspection aisle;
• and
• wherein the disposal aisle is arranged in the vertical direction under the inspection aisle, and the disposal aisle and the liquid-permeable endless belt are arranged in such a manner that dung conveyed on the liquid-permeable endless belt is conveyed into the disposal aisle.

A method for separating dung and urine in an animal pen comprising a separating device having a base frame, a drainage element having a plurality of adjacent drainage channels each comprising an outflow end and a plurality of shoulders between which the plurality of drainage channels extends orthogonally to a drainage direction, wherein a one of the plurality of shoulders between a first drainage channel of the plurality of drainage channels and a second drainage channel of the plurality of drainage channels is formed by a first edge portion of the first drainage channel and a second edge portion of the second drainage channel, and the first edge portion is arranged above the second edge portion, and wherein the first edge portion or the second edge portion is buckled or bent along a longitudinal direction, and a liquid-permeable endless belt with an upper run and a lower run, wherein the drainage element is arranged on the base frame such that a drainage direction of the plurality of drainage channels is directed in the direction of the outflow end, and the outflow end is positioned such that a liquid flowing out of the outflow end reaches a transverse drainage channel, wherein the drainage element is arranged between the upper run and the lower run, and the upper run rests on at least a one of the plurality of shoulders, wherein the upper run serves as a standing area for animals;

• the method comprises the steps of:
• providing a movable, liquid-permeable floor defined by the upper run of the liquid-permeable endless belt;
• supporting the floor on at least one of the plurality of shoulders between each of which extends one of two or more drainage channels each having a drainage end orthogonal to a drainage direction;
• trapping the liquid in the plurality of drainage channels;
• conducting the liquid away in a longitudinal direction of the drainage channels and subsequently in the transverse direction;
• and
• collecting dung from the movable floor.
