Description

one

The invention relates to the field of unloading and dispensing of loose materials associated with poorly charged materials from bunkers.

Famous feeder bulk materials containing a hopper, a cylindrical shell suspended from it on shock absorbers with a conical bottom and a vibrator rigidly fixed on it and an activator with radially arranged trays fixed in a shell with a conical bottom.

The trays of the activator are formed by radially located edges on the working surface of the activator.

A disadvantage of the known feeder is that the design of the activator does not allow to fully utilize the energy of the vibrator, since the energy of circular oscillations is spent only on turning the thickness of the material lying above the activator, and the radial oscillations only radially periphery activator. This reduces the performance of the feeder.

The purpose of the present invention is to improve the performance of the feeder.

The goal is achieved by the fact that the trays of the activator are installed with a gap and with overlapping each other in the plan, while

the upper part of each tray is made convex, and the bottom - concave.

Such an embodiment of the activator will ensure the transfer of circular oscillations into the layer of material lying above the activator, not only for agitating, but also for dumping the material not only in the radial direction, along the entire length of the radial gap gaps between the trays.

The drawing shows a longitudinal section of the feeder and a top view.

The feeder consists of a cylindrical shell 1, to the inner surface of which radially arranged trays 2 are welded, consisting of the upper convex and lower concave parts. The trays are connected in the center by a reinforcing cone 3. A cone 4 is rigidly fixed to the lower edge of the shell and with an outlet nozzle 5.

A vibrator 7 and suspensions 8 are mounted on the carrier flange 6, by means of which the activator is attached to the bunker 9.

The feeder works as follows.

When the vibrator 7 is turned on, the circular oscillations of the outlet surface of the trays 2 are transmitted into the thickness of the material, due to which the arches that have been formed are destroyed. The layer of material above the activator passes into the fluidized state and through the radial gap gaps between the trays enters the concave part of the tray. Under the action of circular component oscillations, which are communicated to the bottom of the tray, the material comes off it and freely slides along the walls of the cone 4, which has an angle of inclination greater than the angle of repose, through the loading opening.

When the vibrator is stopped, the lower part of the tray acts as a locking device. The material between the edges of the convex and concave portions of adjacent trays is poured at an angle of repose.

The cone 3, due to the radial components of the oscillations, ensures the supply of the material above it to the trays and the uniform descent of the material over the cross section of the bunker.
