DE2129644C3 - Conveyor device for powdery material - Google Patents

Description

is rotated so that the powdery material is brought into the center of the housing 1 by the screw 9. If the powdery material reaches the lower end of the tube 6, it is drawn along by the gas flow which penetrates through the ring between the tubes 5 and 6 and emerges from the delivery tube 6 at 12.

The conveyor device according to the invention has the following advantages:

a) Constant and adjustable dosage both with self-flowing powder! Good as

even with not self-flowing powdery ones Good;

b) Simple construction catfish;

c) Very good operational safety and avoidance of blockages, i.e. no blockage even then, if the device works without a throttle cable for some time;

d) Only a small drive force is required, i.e. low energy consumption.

Conveying device for powdery material to create claims: fen, which is simpler in structure, d. H. gets by with significantly fewer moving parts and less 1. Conveyor device for powdery material that is prone to failure. In the case of a conveying device of the type mentioned at the outset, a conveying device of the type mentioned at the beginning of the present invention of a central conveying pipe is to be seen in the fact that the worm conveyer travels through the fore with the aid of a conveying medium - is stationary disk-shaped screw and the pipe is moved, thereby marked- housing is rotatable with respect to this screw.
A preferred embodiment of the invention stationary disk-shaped screw (9) can be seen in the fact that the screw can be rotated by a casing tube (9) which surrounds the housing (1) at a distance from this screw conveyor tube is gen and in a manner known per se over the ring 2. Conveying device according to claim 1, the conveying medium in the space between the pipes characterized in that the screw (9) of 15 can be guided. one surrounding the conveying pipe (6) at a distance- The conveying device according to the invention operates the cladding tube (5) worn and in itself known to utilize the relative Vc rs-hL exercise Way over the annular space between the raw see a screw and a quantity of powder, on the Ren the pumped medium can be supplied. the snail supports itself; so the powder is continuously 30 ierlich conveyed near the end of a gas line; that in the direction of the powder entrainment to the The gas flowing inside the pipe ensures the Conveying the powder to the place of use. In this device, essentially only one egg The invention relates to a conveyor device in motion, namely the housing or vessel device for powdery material, with the one in a pre itself that holds the powder through its rotation counter-storage container takes along a delivery rate through a screw above the screw. This is not only kenförderer in the area of a central conveyor reduces the number of moving parts to a minimum brought and adorned with the help of a conveying medium, but it is also the working principle fundamentally the conveyor pipe is moved. This is also different from the known devices, the introduction of a certain powder flow-through which work with conventional horizontal screw conveyors, Amount of any material iy ei en for the transport, i.e. the powder parallel to the screw axis tion allows certain gas flow.

Furthermore, from the British patent drive 4 is set in rotation. Furthermore, the 804 557 such a device is known, which has a conveyor tube 6 and a conveyor with a conveyor a pair of conveyor screws arranged in parallel, concentrically surrounding cladding tube 5, with two left and right screw parts in opposition to the cladding tube 5 and the cover 2 two sealing positions and means for rotating the worm rings 7 and 8 are provided. The cladding tube 5 ken works in the opposite direction of rotation. There are and the delivery pipe 6 protrude into the interior of the housing usual Conveyor screws, which are used in these well-known sesl. They are also longitudinally movable, depending on conveyors to be used. You lead it but not rotatably arranged.
