US 5,019,256 A · Ultraviolet lamp rack assembly

Abstract

A UV lamp rack assembly usable in an ultraviolet ray wastewater treatment system, the rack including a horizontal hanger bar. When the assembly is installed in a channel through which a stream of wastewater to be treated is conducted, the bar is then supported above the channel in the flow direction of the stream. Depending from the bar at an upstream position is a vertical rod along which sleeves are pivotally mounted at spaced points thereon whereby each sleeve can be swiveled in a horizontal plane. Depending from the bar at a downstream position is a vertical conduit along which detachable lamp couplers are mounted at corresponding points, each coupler housing a lamp socket that is connected through the conduit to a power source. Extending between each sleeve and the coupler corresponding thereto is a lamp unit formed by a transparent protective tube enclosed at its upstream end and housing an elongated UV lamp whose terminal pins are at the downstream end. The upstream end of the unit is slidably received in the rear section of the sleeve, while the downstream end of the unit is securely received in the coupler, the terminal pins of the lamp then being plugged into the socket to render the lamp operative. To remove a particular lamp unit from the rack, it is swiveled to an angular position.

Dependent claims

A UV lamp rack assembly adapted to be installed in a channel conducting a stream of water to be irradiated with ultraviolet rays, said assembly comprising:

(a) a horizontal hanger bar having at an upstream position a vertical rod depending therefrom, and having at a downstream position a vertical conduit depending therefrom;
(b) a series of swivel sleeves pivotally mounted at spaced points along the rod whereby each sleeve can be swivelled in a horizontal plane from a position normal to the rod to an angular position with respect thereto;
(c) a series of detachable couplers mounted on the conduit at corresponding points therealong, each coupler having a lamp socket housed therein which is connected through the conduit to an external power source;
and
(d) a lamp unit extending between each of the sleeves and a corresponding coupler, said unit being constituted by a protective tube which is closed at its upstream end and an elongated UV lamp disposed within the tube and having terminal pins at its downstream end, the upstream end of the unit being slidably received in a rear section of the sleeve beyond which is an intermediate clearance zone, the downstream end of the unit being secured to the coupler with the terminal pins of the lamp plugged into the socket, whereby to remove a particular lamp unit from the assembly, the downstream end thereof is detached from its coupler and the lamp is unplugged from its socket, the unit then being shifted axially in the upstream direction into the clearance zone to a degree sufficient to clear the coupler, so that the unit may then be swung on its swivel sleeve to an angular position permitting withdrawal of the unit from its sleeve.
