Abstract

The invention relates to a dryer for objects, in particular for motor vehicle bodies (1). Known dryers comprise a drying tunnel (6), located within an insulated housing (2), a number of nozzles (25) being arranged in the lateral walls (8) of said tunnel. These nozzles are used to direct hot circulatory air against the objects (1). The circulatory air is extracted from the drying tunnel (6) by means of extraction openings (7) below the objects (1) and is supplied to two air chambers (13) located at the sides of the drying tunnel (6). The circulatory air is extracted upwards via said chambers with the help of fans (18). A heat register (26) is located in each of the two air chambers (13) and is aligned in a substantially vertical direction, said registers consisting of a number of intercommunicating pipe sections that are traversed by hot primary air and are surrounded by the circulatory air. The circulatory air that is heated in this manner is supplied to air distribution chambers (24), which are located on the pressure side of the fan (18), are adjacent to the lateral walls (8) of the drying tunnel (6) and which communicate with the internal chamber of the drying tunnel (6) by means of the nozzles (25).

Claims7

Dependent claims

A dryer for objects, in particular for vehicle bodies, with

a) an insulated housing;
b) a dryer tunnel arranged within the housing, in the side walls of which a plurality of inlets are arranged, via which hot circulating air can be directed towards the objects;
c) at least one suction aperture in the region of the dryer tunnel situated below the objects, via which the circulating air emerges from the dryer tunnel;
d) at least one air space arranged to the side of the dryer tunnel, via which the circulating air is drawn upwards with the aid of a blower;
e) at least one air-diffusing space bordering the side wall of the dryer tunnel, which communicates with the pressure side of the blower and from which the circulating air reaches the space of the dryer tunnel via the nozzles;
f) a piping system located in the interior space of the housing, through which hot primary gases flow and which is in heat-exchange relationship with the circulating air,
characterised in that
g) the piping system comprising a plurality of pipe sections in direct communication with each other wherein the circulating air vertically flows around the plurality of pipe sections and further wherein the piping system is arranged in substantially vertical orientation in the air space which, as a result, is configured as a heating space (13).
