CLASS 82: Drying devices.

Systems or apparatus used for drying (or cooling) certain materials and products serve, in which the material to be processed is oscillating, double-walled, heated hordes (or cooled hordes), which rise when you lift and when you go back perform a downward movement and thereby the automatic advance of the effect good (patent specification No. 86667), show the evil that they do Even for low services they turn out to be far too large to be rational, because they are too drying (resp. to be cooled) materials do not have enough time when passing through a or a number of hordes to absorb enough heat (or cold) to get enough to be dried out (or cooled down).

These considerations led to the arrangement of transverse walls on the trays, thereby the material retained for any length of time and the effect of heat (or cold) on can be exposed to them, etc.

However, this improvement, too, is unsuitable for making drying apparatus in particular usable for larger quantities, since the one-sided supply of heat is not sufficient to produce an essential effect. In order to achieve greater efficiency it is therefore necessary to increase the heating surface, without increasing the size of the trays at the same time, so that a considerably larger amount of heat can be supplied to the goods to be processed. For this purpose, the surface of the trays on which the material moves is provided with pipe sockets α or bracket-like pipes b or attached hollow beads c , or a fixed pipe network (not specified in the drawing) (or with attached heating sockets, etc.) ), which is arranged closely above the tray surface, and thereby achieves the purpose indicated above.

Such drying devices are best for all possible materials or products Use Achievements: However, this arrangement is mainly for drying of crushed lignite for the briquet production in the eye, because the so far for Apparatus manufactured for this purpose are either not sufficiently reliable in operation, or they are very easily explode, because in the absence of a suitable advance coal dust accumulates. The latter is avoided in the schematically sketched apparatus of the present arrangement, since the dry material as a result. the peculiar movement constantly maintained in rapid, but gradually advancing movement becomes and is not only capable because it so to speak is constantly floating in the air, vapors and gases are easily given off, but is also influenced mechanically by the fact that occurring Larger pieces gradually burst through counter-hurling against the heated pipes and so on be brought, but this does not exclude that certain materials are after

A certain degree of dryness has been reached, but otherwise crushed for faster drying can be.

It is also intended to increase the efficiency of these devices, if overheated To use steam and so on. Since, furthermore, when using the specified pipes and so on, the heating surface is increased Cross walls on the shelves cannot be attached well because they are too easy to clog could occur, the feed of the material is regulated in the latter in a different way, namely by greater or lesser inclination of the springs or supports on which the trays are at rest, and by increasing or decreasing the stroke of the drive shaft (Crank or eccentric), and this allows z. B. by enlarged stroke and almost vertical position of the feathers and so on, a very lively one, but still slight achieve progressive movement of the material.

Claims (1)

Patent claim: Vibrating tray for drying or cooling, characterized by the arrangement of resonating or stationary tubes or beads, which serve to ensure the effective To enlarge the heating or cooling surface of the tray, and in which the drive and the Support is chosen so that the material, although a strong back and forth, but the executes corresponding, only slightly advancing movement according to the respective requirements. For this purpose ι sheet of drawings.
