Description

The invention relates to devices for unloading difficultly flowing materials from a container, in particular to vibratory feeders, and can be used in areas of the national economy, such as the construction of the chemical industry and others.

The aim of the invention is to provide the possibility of controlling the flow of material and intensifying its unloading

Establishing with the possibility of vibration of the individual walls of the unloading part of the feeder, supplying each of them with a vibrator and connecting each wall to the adjacent ones by means of elastic-elastic connections eliminates sticking and compaction of the discharged material on the walls of the feeder.

Fig, 1 shows the proposed vibratory feeder, a general view; figure 2 - section aa in figure 1; on fig.Z - section bb in figure 1.

The vibrating feeder includes a housing, along the perimeter of the lower opening of which, on a flexible insert 2 made of rubber sheet or conveyor belt, detachable separate walls 3 are mounted, interconnected at an angle of 90 ties 4 from elastic-elastic material - rubber sheet or conveyor tapes. Vibrators 5 are attached to the outer sides of these individual walls 3, and material outflow drivers in the form of vertical ridges 6 are rigidly attached to the inner sides. In the plan, an equilateral triangle with each wall 3 forms the free end of the vertical ridges 6 in the plan. center of the curve and symmetrically pointed. Vertical ridges 6 have a different height, symmetrically increasing from the vertical faces of the walls 3 to their middle. The distance between the ridges 6 in the longitudinal and transverse directions is 5-10 of the thickness of the ridge.

Vibrating feeder works as follows.

The case i is filled with concrete or any other material and transported by any known method to the place of unloading. Include either any one vibrator 5, or f any combination two, vibrato

ra 5, or in any combination, three vibrators 5, or all four vibrators 5.

When working a particular vibrator

5 vibrates that wall 3 to which the vibrator 5 is attached and attached to the wall 3 vertical ridges 6, resulting in a concrete mixture or other viscous material in the vessel 1 and between the walls 3 that is in contact with the vibrating ridges 6 and wall 3, liquefies and expires intensively from

- capacity. When the vibrator 5 is turned off, the outflow of material immediately ceases.

The inclusion of vibrators 5 in any combination of one to four pieces

allows you to adjust the discharge capacity of the material and the width of the strip of material being unloaded in a wide range.

With all four vibrato / 5 moat 5 operating, the material unloading performance will be maximum, significantly exceeding the performance of all known vibratory feeders,

Q The inclusion of vibratogs / s 5 by one or two, or three, in addition to the capacity control, allows one to change the place of discharge and the width of the strip, i.e. regulates the flow of material.

The different height of the vertical ridges 6 is dictated by different loads5 on them5 both dynamic (when loading the capacity of the case and between the walls 3) and static (when transported by the Research Institute of Vibrating Feeder when its capacity is filled with material)

formula of invention

Vibrating feeder 5 comprising a housing and mounted under it on a flexible insert with the possibility of oscillation of the discharge part with a material expulsion booster, characterized in that 5 in order to ensure the possibility of controlling the material supply and unloading intensification, the discharge part is made

as separate walls with a vibrator w fixed on them and elastic-elastic connections interconnected by them, and the outflow booster is made in the form of rigidly fixed on

each wall of vertical ridges, with a height that gradually decreases along the arc to the axis of the bunker, the free ends of which form in the plan an isosceles A

triangles, with the distance between the ridges in the longitudinal and transverse directions being 5-10 of the thickness of the ridge.
