"Vibratory conveyor ^H

The invention relates to a vibrating conveyor trough to convey ▼ on bulk goods, in which the main part of the grain size is below 100 / y. lies.

So far, such bulk goods, such as cement or gypsum, usually transported with pneumatic conveyors, for example cement in a vibrating conveyor trough Oscillating movement is compressed so strongly that a flow movement ceases to exist.

The object of the invention is now to create ways to also τοrbesohriebene bulk goods with vibrating conveyors to be able to transport

The solution to this problem essentially characterizes you by at least one chamber which can be acted upon by pressurized gas and which is arranged above the channel bottom and which is gas-permeable towards the channel Walls is limited.

A preferred and inventive embodiment of the above The object is characterized by an extending over the entire channel bottom, at a distance of the latter arranged, gas-permeable intermediate floor and at least one in the channel floor and the intermediate floor through-air duct opening into the confined space, whereby preventive

Furthermore, the intermediate floor made of material is more obvious Structure, the cells of which are in communication both with one another and with the outside air. Furthermore, an advantageous and inventive feature of the pre-described object is characterized by the use of clay sintered metal as the material for the intermediate floor.

In addition, an advantageous and inventive feature of the subject matter described above is identified by the fact that the Gas pressure in the chamber in mm of water column on the layer thickness of the bulk material in mm on the intermediate floor approximately like 3 to 4 iu 1 behavior.

In this way, a vibrating conveyor trough is obtained, in which the dusty or fine-grained material to be conveyed is in the Hovered and influenced by the vibrator Binne is set into a flowing movement, so to speak, whereby can also be promoted upwards. In addition, the subject of the invention is compared to known, previously used for this device due to a significantly greater economic efficiency * The subject of the invention also enables use as a task device sum exact dosing of fine-grained bulk materials, because the material is conveyed by the oscillating movement of the chute.

An embodiment of the invention is shown in the drawing and is described in more detail below. Show it

Here, the base 1 of a trough-shaped channel 2 made of steel engages an electromagnetic vibrator 3. Above the gutter bed 1 and at a small distance of a few centimeters is an over The seeded inner floor 1 is arranged as an intermediate floor * made of gas-permeable plastic (trade name Plexolit) that extends. Furthermore, it opens into room 5 «with the floor of the channel and the intermediate floor 4 a Durokluftleitung 6 a · Above the Channel 2 is also provided with a funnel 7 that partially protrudes into the latter.

If cement, i.e. a hygroscopic bulk material, in which the main part of the grain size is less than 100 ^ a, is to be dosed in a further preprocessing plant with the prescribed device, for example, room 3 is subjected to compressed air before the cement is poured into the channel , with a layer thickness of approx. 3 cm of the bulk material 8, a constant pressure of approx. 100 to 120 mm water column is sufficient. Then the vibrator 3 is switched on, with the help of which the cement is set into a flowing movement in the direction of action of the vibrator. By changing the intensity of the vibrator, the conveying speed and conveying capacity can be changed as with conventional vibratory feeders.

All new disclosed in the description and / or drawing Single and combination features are considered essential to the invention.
