The present disclosure is directed to devices and kits configured to displace noxious odors generated by pet waste or excrement from within pet waste receptacles, such as a litter box kept within the pet owner's living space or home to areas existing outside of such owner's living space via a preexisting window therein. More particularly, a flexible, elongated duct is coupled to an exhaust hole in any hooded litter box on one end, and on another end, coupled to an electrically powered fan and universal window vent panel. When the window vent panel is sealedly disposed in a window and the fan is powered on, noxious air within the receptacle is drawn through the exhaust opening in the enclosure, the duct, and an exhaust opening in the window vent panel to an outside of such window.

A livestock blower apparatus for blowing air through a flexible hose onto an animal. A pair of blower units are enclosed within an interior space of a housing. The blower units are adapted to draw air through housing inlet openings and force it through a Y-shaped conduit out through a housing outlet opening without the air coming in contact with the housing interior space. A cooling fan is provided at a housing cooling inlet opening and blows air into the housing interior space. Another cooling fan is provided at a housing cooling outlet opening and draws/blows air out from within the housing interior space. The blower units are thereby protected from the elements and noise generated by them is muffled by the housing, and the blower units are cooled for minimizing the heat that may be transferred to the air being blown onto the animal.

Agricultural structures for housing livestock and/or agricultural commodity, the structure having a floor that is inclined between first and second walls and a roof that is substantially parallel to the floor. In some aspects, the floor is configured such that a bottom of the first wall is vertically higher than a bottom of the second wall with the bottoms of the first and second walls being level with the underlying ground. In some aspects, a first portion of the floor adjacent to the first wall is at a first elevation, a second portion of the floor adjacent to the second wall is at a second elevation that is vertically lower than the first elevation, and a bottom of the first wall is at a third elevation that is equal to or lower than the first elevation.

A structure for sheltering and cooling livestock may include a concrete floored barn having an improved evaporative cooling system. The cooling system may include a misting stack having air inlets, a mixing chamber, and three cooling zones wherein the cooling zones correspond to three different temperature ranges. Each of the cooling zones may include a plurality of nozzles which produce a mist. As air passes through the mixing chamber, the mist may evaporate and cool the air. The cooling system may further include a plurality of large exhaust fans located at an end of the barn distal from the misting stack. The fans may draw the cool air through the barn, over and around the livestock, and out of the barn.

A henhouse includes a gable, a sidewall, and a roof. An inner chamber parallel to the sidewall is provided in the middle of the henhouse. The inner chamber includes an inner wall parallel to the sidewall and an inner roof. A partition is provided between the sidewall and the inner wall. An air inlet plate is provided between the two inner walls located below the inner roof. A pressure chamber is formed between the inner roof and the air inlet plate. A premixing chamber is formed between the inner roof and the roof. A plurality of fans and air inlet windows are uniformly provided on the inner roof. A plurality of air inlet holes and small inlet windows are uniformly provided on the air inlet plate. A plurality of wet curtains and an air vent are provided on the sidewall. A plurality of air outlet slots are uniformly provided on the inner wall.

An apparatus for collecting a gaseous pollutant from air within a poultry or other concentrated animal feeding enclosure may comprise multiple vertical panel-beds each containing a solid sorbent; a fan to pass the air within the poultry enclosure through the multiple vertical panel-beds and over the solid sorbent; an outlet gate configured to release the solid sorbent from the multiple vertical panel-beds after the fan passes the air over the solid sorbent; a regeneration vessel configured to regenerate the released solid sorbent by recovering the gaseous pollutant from the released solid sorbent; and a conveyor configured to return the regenerated solid sorbent to the multiple vertical panel-beds.

An automated litter device having: a base; and a chamber configured for retaining a litter and rotatably supported by the support base, wherein the chamber includes: an entry opening so that an animal can enter and exit the chamber; and a waste opening generally opposing the entry opening configured so that an animal waste passes through the waste opening into the base upon rotation of the chamber; wherein the automated litter device includes one or more of: i) one or more sensors located adjacent to the entry opening which are adapted to sense the presence of the animal within the chamber, the presence of the waste in the base, a level of litter in the chamber, a position of the chamber relative to the base, or any combination thereof; ii) a filtering system configured for reducing, eliminating, and/or preventing, malodors building in the base; and/or iii) a litter dispenser in communication with the chamber to transfer some of the litter to the chamber.
