Abstract

The invention relates to devices for storing and unloading hard-flowing materials. The purpose of the invention is to increase the reliability of work. The vibration bunker is located under the static bunker 1 and contains symmetrically located right 2 and left 3 sections, elastically interconnected with a gap by the working spring 4 and sealed by a hermetic seal 5. Each section is equipped with vibration exciters 6 and 7 mounted on rigidity cables, and is located by means of shock absorbers 8 on the supporting structure of the bunker 1. The outlet of the bunker is covered from above with a convex discharge canopy consisting of the right 9 and left 10 parts arranged with a gap and rigidly attached respectively, to the right 2 and left 3 sections of the bunker by means of t g 11. Parts of the discharge canopy can be connected by a spring or eye to the axle. 3 hp ff, 2 ill.

(Reg. 1

The invention relates to devices for storing and unloading hard-flowing materials and can be used in the mining, chemical, food and other industries.

The purpose of the invention is to increase the reliability of work.

FIG. 1 shows the vibratory hopper, general view; in fig. 2 - a visor with a connecting spring and an eye with an axis.

The vibratory bunker is located under the static bunker 1 and includes a housing having symmetrically vertical vertical right 2 and left 3 sections.

ten

tizator 8, the rigidity of which is chosen relatively small, based on the far-resonant tuning.

Together with anti-phase oscillating sections 2 and 3, according to the same law, parts 9 and 10 of the discharge canopy rigidly connected with them oscillate. At the same time, the passage gap B between the wall of the bunker and the visor periodically changes its value with the frequency of vibration, and therefore the sticking material that occurs in it during the expiration of the dumping material is effectively eliminated according to the similar principle of destruction of the arches above the outlet opening of the bunker A. Along with this

elastically interconnected working spring alternating divergence and convergence of part 4 and sealed with a hermetic seal of the discharge canopy causes disruption 5. Each section is equipped with a vibration shield in the array located above it

the drivers 6 and 7, installed on the post-bulk material, contributes to stiffness, and is established through cracks in it, skid surfaces of shock absorbers 8 on the supporting structure and other factors contributing to

hopper information 1. Sections are set between 20 outflow. Due to this efficiency

the outflow of material from zone C is also increased.

The use of a discharge canopy consisting of two parts, rigidly connected with the corresponding sections of the slot with a gap.

The housing has an outlet, which is covered from above with a convex discharge cap consisting of a right 9

The left 10 parts of the vibrating bunker installed from the vertical slot, allows to significantly increase the coagulating effect, the throughput and the uniformity of the outflow of the bulk material from the vibrating bunker.

Claims (4)

1. A vibratory hopper comprising a housing with an outlet, consisting of two elastically interconnected with rum between themselves and rigidly attached respectively to the right 2 and left 3 sections of the bunker by means of t g 11. The plane of the gap between the portions 9 and 10 of the cap may coincide with the plane of the gap between the sections. 2 and 3 cases. Parts of the discharge canopy can be composed of a spring 12 or a hole with an axis 13. Bunko) works as follows. thirty Year of exposure to exciters 6, a gap of vertical sections, placed and 7 sections 2 and 3 begin to oscillate antiphasally in the horizontal plane. In this case, the walls of the section alternately converge, then diverge by a double value of a given amplitude of oscillation. At the same time, the vaults arising in the area of the outlet-40 of the bore hole A of the bunker are effectively broken. The pot n unloading of the hopper occurs without any need for a given manufacturer. the magnitude of the amplitude depends on the strength of vibration exciters 6 and 7 and the mode of operation of the vibration system, determined by the rigidity of the working spring 4. The mode of operation of the vibration system for a given design is most often colonic as the least energy-consuming. The magnitude of the dynamic loads on the supporting structures is determined by the stiffness of the amor45 over the outlet of the housing, a visor and exciters, characterized in that, in order to increase reliability of operation, the visor is made of two parts spaced with a gap relative to another, each of which is rigidly connected to one of the hull sections. 2. A bunker according to claim 1, characterized in that the plane of the gap between the parts of the visor coincides with the plane of the gap between the sections of the housing. 3. Bunker according to Claim 1, characterized in that the parts of the visor are interconnected by means of connect. 1 spring. 4. A bunker according to claim i, characterized in that the portions of the visor are interconnected by means of a grouse and an axis. tizator 8, the rigidity of which is chosen relatively small, based on the far-resonant tuning. Together with anti-phase oscillating sections 2 and 3, according to the same law, parts 9 and 10 of the discharge canopy rigidly connected with them oscillate. At the same time, the passage gap B between the wall of the bunker and the visor periodically changes its value with the frequency of vibration, and therefore the sticking material that occurs in it during the expiration of the dumping material is effectively eliminated according to the similar principle of destruction of the arches above the outlet opening of the bunker A. Along with this the gap of the vertical sections, placed over the outlet of the housing, a visor and exciters, characterized in that, in order to increase reliability of operation, the visor is made of two parts spaced with a gap relative to another, each of which is rigidly connected to one of the hull sections. 2.
