SU444705A1 - Volumetric Vibrator - Google Patents

Description

The invention relates to devices for volumetric dosing of powder materials and can be used in the metallurgical, chemical and building materials industries.

Known designs volumetric vibrating, containing a movable body and a vibrator.

However, such vibrating feeders are not adapted for operation of pneumatic conveying systems and do not ensure uniform delivery of material to measuring devices.

The purpose of the invention is to provide reception of the aerated material from the pneumatic system of the dense layer, its degassing and uniform flow to the measuring device.

This is achieved by the fact that the body of the vibrating dispenser is made in the form of a hollow annular ring with annular plates inside and a tangentially installed discharge pipe, the vibrator being installed in the central part of the annular chamber, and in its upper part a degassing nozzle is made.

The drawing shows a vibrating drum, longitudinal and transverse sections.

The volumetric vibrating dozer consists of an annular shrinking chamber S. with supporting consoles 2 and a frame 3 on which an annular chamber I, is installed by means of springs 4. oscillations of a certain frequency and amplitude, the rotation of the unbalanced shaft of the vibrator 6 is carried out from a regulated DC motor 7 through a flexible element 8, for example, a durit hose.

The annular chamber is loaded with aerated material via uaf

PySoK 9, which is connected by a corrugated sleeve to a transport air pipe, JUui removes air from the air outlet from the circulation compartment at its upper point, a degassing nozzle 10 connected to the exhaust. The dosing material is withdrawn from the chamber through the tangential nozzle -Ii. To accelerate the circulation of material inside the annular chamber before the nozzle 1, annular plates 12 are embedded ..

The vibrating docker works next. in a way.

The aerated material from the pneumatic system is fed through the loading nozzle into the annular chamber, making circular oscillatory movements of the springs under the action of the vibrator.

When the annular chamber is filled, the aerated material is released from the air that escapes through the degassing nozzle, levels the density and begins to circulate through the annular chamber in the direction opposite to the rotation of the unbalanced shaft of the vibrator b, increasing the circulation rate in the zone of the accelerating ring

plates 12. The dosed material flow is discharged through the pipe AND,

The change in the rate of circulation of the material in the chamber, according to the performance of the dispenser, is carried out by changing the oscillation frequency of the vibrator with the help of a direct current electric motor.

The dispenser allows uniform volume dispensing of the material coming from the pneumatic system with aero-flow of a dense layer,

SUBJECT OF INVENTION

A volumetric vibrating drum containing a movable body with inlet and discharge nozzles and a vibrator characterized in that, in order to ensure uniform dosing of powder-like materials in aero flows, the vibroshock body is made in the form of a hollow annular chamber with annular plates inside and a tangentially installed discharge nozzle, the central part of the annular chamber, and in its upper part, a degassing patra is made: the side.
