Description

(54) MULTI-SECTIONAL VIBROCONVEYER

one

The invention relates to devices for the vibratory movement of bulk materials and can be used in the chemical, mining, metallurgical and other industries.

A vertical vibrating conveyor for bulk materials is known, comprising a working member in the form of a tube composed of two halves interconnected by elastic elements with horizontal partitions, each half of the conveyor is equipped with an exciter 1.

The closest technical solution to the invention is a multi-sectional vertical vibroconveyor, including a working member of interconnected sections, each of which is made in the form of a pipe with a hopper and an inclined bottom 2.

The disadvantage of this conveyor is the impossibility of its complete emptying.

The aim of the invention is to provide the possibility of a complete emptying of the vibrating conveyor.

The goal is achieved by the fact that the working body is made in the form of two rows of sections, forming a channel, connected by openings by the lower part of each section, inside which is located a piston that is installed with the possibility of fixation by means of a stopper.

FIG. 1 shows a multi-section J vertical vibroconveyor, longitudinal section; in fig. 2 - the same, left view; in fig. 3 - section A-A of FIG. G.

The conveyor consists of two rows of sections 1, vibrodrive 2, springs 3, and elastic rubber elements 4, which are mounted 10 between two rows of sections 1.

The rows of sections with their rear walls 5 and the continuation of the side walls 6 form a channel 7.

Each row of sections is mounted on springs 3. Each section is made in the form of a pipe 8 with a funnel 9 and an inclined bottom 10.

The conveyor is equipped with a discharge pipe 11.

Inside the channel 7 is a piston 12, 20 installed with the possibility of fixation by means of the stopper 13.

The dimensions of the ground correspond to the cross section of the channel 7. In the upper part of the channel 7 there is an abutment 14 for the piston 12. Through the holes with

the plugs 15 .n communicate with the sections.

The vibroconveyor is equipped with a vibration actuator 2, made in the form of two unbalanced vibration exciters, synchronously rotates towards one another.

The conveyor works as follows.

The material poured into the feed funnel 9, with directional vibrations, moves along the inclined bottom 10 and rises through the pipe 8, the filling fee over the entire cross section, is poured into the feed funnel of the next section, moves up and out of the last section through the loading nozzle 11.

When sections 1 are emptied, at the end of the transportation process, the plugs 15 are opened and the material is poured into the piston 12 through the holes. Then the piston 12 is released from the stopper 13 from fixing.

Under the action of the disturbing forces of the vibrodrive 2, both rows of sections oscillate along elliptical trajectories m in opposite directions. In doing so, they first come close, grip the piston 12 and move it upwards with the material out. empty sections. Then the rows of sections 1 move away from each other, lose contact with the piston 12 and, idling, are lowered to their initial position.

Due to the high oscillation frequency, the effect of continuity of force on the piston occurs. When turning off the vibration drive 2, the piston 12 falls down.

Depending on the properties of the material being transported, emptying is carried out at once from several sections or sequentially from each section.
