Description

(54) VIBRATION HOPPER

The invention relates to the builder of mechanical engineering, more specifically to the storage and unloading of bulk materials from bunkers, and will find application in the building materials industry, in food and other public households. A vibrating hopper is known, on the wall of which a spring-loaded vibrating plate l is installed. However, such a bunker requires large energy consumption, since in order to intensify the unloading of bulk materials throughout the entire bunker volume, it is necessary to install vibrating plates on all walls of the bunker. A vibrating hopper for bulk materials is known, which contains a bottom that is rotatable relative to the horizontal axis, I have a FLOW to the discharge hatch, and a wall 2}. The disadvantage of this vibratory hopper is the uneven discharge of material from the hopper due to its sticking to the bottom. The goal was invented and - increased efficiency by unloading. This is achieved by the fact that the bottom is spring-loaded and a vibrator is fixed on its underside, and the wall of the bunker is arcuate. The drawing shows a vibratory hopper. The bunker is a tank 1, in the front wall 2 of which there is a discharge opening 3, blocked by a bolt 4. The bottom 5 is made movable by fastening it to the front wall of the bunker using a hinge 6. The spring 7, installed under the bottom, ensures its rotation from the bottom the position that the bottom occupies with a fully loaded hopper in the upper position as the material is consumed, the vibrator 8 is rigidly fixed to the bottom. The back wall of the 9 bunker at the site of contact & ni with the bottom has an arcuate shape, and the sides of the bottom in contact with the side and back walls of the bunker have sliding elastic sealing elements 10. The vibratory hopper operates in the following sequence. When the hopper is fully loaded, the bottom 5 is in a horizontal position. For unloading material

from the hopper include a vibrator 8, under the action of which the material begins to pour out through the discharge opening 3. A decrease in the amount of material will result in; loosening the impedance will cause the bottom to rise, thereby increasing the outflow of the material through the discharge opening. The rotation of the bottom under the action of the spring will occur until all the material is unloaded from the bunker.;,;; :::. ;; ....:.:; ..,; :: .-. ::: ..: ;; ::. : /

Thus, the proposed design of the bunker provides efficient unloading of bulk material due to a flexible bottom with a source of vibration, with minimum energy consumption.
