Chute dryer with inclined movable sliding surfaces.

Patented in the German Empire on March 17, 1909.

The invention relates to a device for drying and kilning any Good things, which are illustrated in the drawing using one embodiment, for example is.

Fig. Ι shows a vertical section through the apparatus, Fig. 2 details of the lower Shaking surfaces, Figures 3 and 4, cross-sections of the upper rotatable devices.

The device consists 1. of one or more identical rotatable devices i, which are stored in a brick evaporation chamber 3. These devices can also be rotatably arranged in an independent metal housing, which in turn can be arranged either fixed or movable. Any of these can also Devices together with a jacket 19 enveloping the same on all sides (Fig. 4)

zo turn, the end faces for the entry and exit of the goods to be dried and the Gases are open. In this case the jacket itself forms the evaporation chamber; 2. off a number of perforated or solid areas 4 which alternate in opposite directions are inclined and the longitudinal section of which runs along an arc, the inclination of which the downward slide caused by the shaking movement described below at all points of the good promotes.

The material to be dried is fed into the apparatus by a suitable conveying device 5 passed and falls on the first device 1; as a result of the rotary movement and inclined arrangement the latter as well as the advancement caused by the constant introduction of fresh goods, the goods come from one end of the device 1 to the opposite end and then falls into the second device 2, through which the good runs in the opposite sense. Emerging from the last, the good falls on a suitable distributor 6, which spreads the good evenly the upper part of the uppermost surface 4 distributed. By the shaking motion of the latter The material slides slowly downwards on this surface until it hits the upper part of the lower part The second surface 4, which is arranged on the first surface, falls on which it also descends slides and from which it passes onto a third, then a fourth surface, etc., until it finally falls on a conveyor 7 in the desired dry state, which transports the good to the outside.

The non-rotatable elements 4 of the apparatus are alternately in opposite directions Directions inclined surfaces formed in their upper parts by hinges 11 or the like connected to one or the other vertical wall of the chamber is. The top edge 12 of each face is supported by the wall, while the bottom edge the same describes an arc and hereby lifts a bar 14 which can be rotated about the axis 13, whose downward movement is limited by a stop so that between her and the surface 4 a predetermined free passage for the next surface falling good remains.

To force the good to fall is one (or two) more appropriate Way interconnected surfaces 4 a

rotatable roller 15 is provided, which by a non-circular disk 16 o. The like. Alternately is raised and lowered. After z. B. the disk 16 de surface 4 with the bar 14 lifted to its highest position and held it for some time, the same begins to lower the two parts again until the bar 14 stops is stopped.

At the same time, the roller 15 falls into a notch provided in the disc 16, whereby the surface 4 suddenly falls onto a stop 1.7 and a shaking movement generated, which partially falls through the goods through the between the bar 14 and the lower edge of the surface 4 resulting gap.

Immediately after the surface 4 has been shaken, the disk 16 comes back with the roller 15 in contact to bring the surface back to its upper position.

The material located near the lower edge of each element 4 slides from it to the next element, while- between the lower and the upper edge of the The goods located in the element slowly approach the lower edge.

In Fig. 2, two elements 4 coupled by a frame 10-9 are shown. the individual disks 16 are arranged so that the individual or paired elements 4 should be shaken at the same time. To allow hot air to escape between the Edges of the broad sides of each element and the relevant walls of the chamber prevent these edges by flexible strips of asbestos o. Like. Fabric with the Walls connected. The elements 4 are perforated or perforated; the gas mass flows through them either from bottom to top or vice versa. When the elements 4 are formed by solid surfaces, the rotatable strips 14 are not arranged, so that the gases can flow upwards or downwards. But when the elements are broken - as is generally the case The case is - the passage is always only between one element or pair of elements open, while all other elements or element pairs are closed on all four sides are so that the gases are forced to penetrate through the surfaces to be released from a To get to the other side.

Claims (2)

Patent Claims: 1. Chute dryer with inclined movable sliding surfaces, characterized in that that a rotatably mounted bar (14) is arranged over the lower edge of each sliding surface (4), the rotation of which is limited downward by a stop so that when the surface (4) is lowered between the latter and the bar a free one There is a gap for the goods to fall through onto the next surface (4). 2. Chute dryer according to claim 1, characterized in that the sliding surfaces are so curved that at their point of attachment, where the deflection is small, the slope is strong, at the opposite At the end, however, the rash is severe and the inclination slight. 1 sheet of drawings.
