Sealing for the goods transfer points on vibrating machines, in particular vibrating conveyors for hot bulk material

"The invention relates to a seal for the Gutübergabestellen to oscillating machines, in particular to Schwingför- _Λ

those for hot bulk goods.

It is known for vibrating machines that the material supply or removal openings that vibrate with it by means of bellows or to connect sleeves made of rubber with the corresponding fixed material supply or material removal organs and to seal the transfer points against the escape of dust, gases or vapors.

for higher temperatures, as in the case of hot bulk goods at the " places to be sealed occur, the seals must be heat-resistant, so that initially tight metal mesh and Asbestos cloth come into consideration. However, these resist the strong mechanical alternating stresses, in particular in interaction with the fine-grained material that sets in the tissue, this is insufficient and requires frequent repairs.

ORIGINAL INSPECTED

The object of the present invention is to provide a simple and reliable seal. The task will be solved according to the invention in that connected to the vibrating working mass material inlet or outlet nozzle a collar is tightly fastened, which is directed downwards at a distance from the nozzle wall, circumferentially with one another has connected blocking surfaces which are connected to a fixed part of an upstream or downstream material dispensing or receiving device with liquid immerse the filled inside. The above-mentioned disadvantages are cost-saving due to the arrangement according to the invention avoided. Furthermore, the arrangement facilitates an operational separation between vibrating and stationary Split at the point to be sealed.

In the embodiment of the subject of the invention, it is proposed that to align four blocking areas in the plan at right angles and in pairs parallel to each other, that one pair points in the direction of oscillation of the machine and the other pair vertically downwards. This will advantageously achieved that the blocking surfaces according to the movement of the vibrating machine in the liquid in essentially move up and down in the direction of their planes, with the free edges of the blocking surfaces always below the liquid level. This will

is enough that, despite the movement of the blocking surfaces, the liquid essentially rests.

In a further embodiment of the invention it is proposed that the free edges of the blocking surfaces immersed in the liquid to be designed in the shape of a cutting edge to also only a minor one To rule out turbulence of the liquid to a large extent.

furthermore, the senses have a passage granting the blocking surfaces Cover on, which protects against falling objects as well as splashing of the liquid in the event that the oscillating movement instead of a straight line, for example an approximately elliptical curve follows.

Furthermore, the channel has a sump which is connected to a drain device for easy cleaning to allow the gutter.

Finally, the gutter with a liquid supply line and a drain pass, ao that evaporated or over the Suepf withdrawn liquid can be continuously replaced, the gutter expediently with a level regulator for regulation of the FliieeigkeitsBUlaafe is provided.

A preferred exemplary embodiment is illustrated with reference to the drawings the invention explained. Show it:

1 shows a longitudinal section parallel to the conveying direction through the product discharge end of a vibratory conveyor with the device according to the invention,

FIG. 2 shows a cross section through the device according to FIG Line II - II, and

Fig. 3 is a plan view of the Hinne, in which two Parts on opposite sides have broken out.

According to FIG. 1 and FIG. 2, a material outlet nozzle 3 which is continuously connected to a conveyor chute 1 and is arranged perpendicular to the conveying direction 2 has a collar 4 that tightly encloses it. The collar 4 is adjoined by two blocking surfaces 6 pointing downwards parallel to the direction of oscillation 5 and two perpendicular blocking surfaces 6 ·. These are each immersed in a liquid 7, z. a. i / ater, filled Hinne 8, which with aea; Nozzle 9 of a nachgecrdneten, fixed, not shown 3-ut receiving device is connected. The back has two perpendicular ones

Outer wall 10 penetrating .Pipe socket 11, of which one is designed as a liquid supply, the other is designed as a drain. A sump 12 is arranged on the underside of the channel, which is advantageously equipped with a pull-off device 13 in Connection. On its upper side, the channel 8 has a cover 14 which advantageously opens the channel 'downsized.

In Fig. 3, the general structure of the channel 8 is based on a plan view shown schematically.

For example, in connection with the material outlet side A vibratory conveyor, in particular the subject matter of the invention explained for hot bulk material, also allows versatile Possible uses and is advantageously suitable for everyone between a vibrating and a stationary part Dust and odor seals to be arranged accordingly.
