Description

The invention relates to devices for storage and unloading of bulk materials, prone to caking and arching, and is intended for use in the construction, chemical, food and other sectors of the economy. ^5- zC The vibroactivator of the company Vibra Screw Fidere (USA) for hard-flowing materials, consisting of a housing to which a movable vibrating cone and a vibrator are attached at the bottom, [1J. 10 The disadvantage of this device is that the smooth surface of the cone does not allow the vibration energy to be transmitted to a considerable depth in the layer of material above the cone, which leads to caking of the material and does not ensure uniformity ^{5 of the} unloading of the material.

Also known is a vibration unloader for hard-flowing materials, comprising a housing with a conical bottom, a turbulator, with radial ribs ₂ mounted on it and a vibrator [2].

The disadvantage of this device is that it does not provide uniformity of unloading of bulk materials, since the turbulator and radial ribs vibrate with the same parameters, which leads to a deterioration in the uniformity of unloading of materials having an increased tendency to caking and arching.

The aim of the invention is to increase the uniformity of unloading of bulk material by providing regulation of the amplitude of the ribs relative to the turbulator.

To achieve this goal in Discharger for trudnosypuchih Ma- materials under _35, comprising a housing with a conical. the bottom, a turbulator with radial ribs fixed on it and a vibrator, each radial rib is fixed to the turbulizer by means of a pair of rods With elastic elements mounted at the ends of the ribs, with 40 elements, each pair of rods connected by means of a load, reinforced with the possibility of its movement along rods of the radial rib.

In FIG. 1 shows a vibration unloader

For hard-flowing materials, general view;

in FIG. 2 - node 1 in FIG. 1.

The “unloader” for hard-flowing materials consists of a housing 1, in the lower part of which by means of shock absorbers 2 a turbulator 3 is mounted with a vibrator 4 rigidly fixed on it. Radial ribs 7 are fixed to the turbulator 3 by means of elastic elements of the 5th pair of rods 6. On the rods 6 weights are fixed on the opposite radial ribs 7 of the side 8. '

Vibro unloader for bulk materials works as follows.

Material® loaded through the upper part of the housing 1, enters the turbulator 3. When the vibrator 4 is on, the turbulator 3 oscillates in a horizontal plane. Radial. Numerous ribs 7, interacting with the material, transfer significant amounts of energy to it due to the resonant or near-resonant mode of vibration of the ribs 7, provided by selecting the required stiffness of the elastic elements 5 taking into account the weight of the loads 8 and the distance a from the center of mass of the loads to the center of swing of the radial ribs according to known dependencies.

Under the influence of vibration, the material in the contact zone with the turbulator 3 and the radial ribs 7 acquires flowability and is discharged through the annular gap b.

Using the proposed device will improve the uniformity of the unloading of the mass due to a more intense and deeper vibration of the material in the unloading and destruction zone of the arch formations and agglomerated structures by intensely vibrating radial ribs, at. relatively small vibration parameters of the turbulator, which will ultimately reduce the downtime of both the vibration unloader and the equipment associated with it in the production line.
