Description

(54) VIBRATION BUNKER

one

The invention relates to devices for unloading bulk materials and can be used in the chemical, mining, construction and other industries.

According to the main author. St. No. 628042 is known vibrating bunker, including a fixed body mounted on supports, and two vertically suspended sections, equipped with U-shaped beams covering them, on which vibrators and elastic elements are fixed, with the ends of the U-shaped beams made with shaped protrusions, and elastic elements are made prismatic and are covered with a tension clamp 1.

However, this bunker does not provide efficient unloading of difficult-to-flow material due to its sticking to the walls and, as a result, arching.

The purpose of the invention is to increase the efficiency of material unloading.

To achieve this goal, the bunker is equipped with an inclined chute rigidly fixed on one of the sections, and a flexible plate, one end of which is fixed to the other

sections, and the second end is inside said gutter.

In addition, in order to dispense the material by adjusting the gutter cross section, the flexible plate is fixed in the gutter with the possibility of moving perpendicular to the movement of the material.

At the same time, the chute and the flexible plate are made expanding in length.

FIG. 1 shows a bunker, general view; in fig. 2 - cut. A-A in FIG. one; in fig. 3 shows a section BB in FIG. one.

The vibratory hopper consists of a fixed case 1 mounted on supports 2 and two sections 3 and 4 vertically suspended to it, equipped with vibrators 5 and 6. The sections 3 and 4 are connected to the fixed part with the help of suspensions 7. Vertically suspended sections on their the ends have protrusions between which resilient elements 8 and 9 are located. Between themselves, these sections are sealed by a flexible plate 10 attached to the sections by means of bolts 11. On section 4, an inclined chute 12 is rigidly fixed, inside which is placed a flexible plate stina 13, one end of which is fixed

section 3, and the other inside this trough, with the possibility of adjusting the flow area with the help of the handwheel 14, screw 15, nut 16 and support 17. In addition, the trench I is a flexible plate for improving transportability made expanding in the course of the material.

The bunker works in the following way.

When vibrators 5 and 6 are in operation, due to the presence of elastic elements between the sections, their self-synchronization is achieved, as a result of which the two halves of the hopper oscillate in antiphase with the same amplitude, thereby providing a convertible effect in the bunker's working volume. The antiphase vibrations of the half of the hopper cause the longitudinal-lateral deformation of the plate 13, contributing to the elastic waves in it. The transverse undulating vibrations cause a strong motivating effect inside the gutter. A smooth adjustment of the capacity from zero to the maximum value is achieved by a corresponding change in the degree of overlap of the cross section of the trough with the help of a screw 15.
