Description

one

The invention relates to a lifting and transport equipment, namely, vibration devices for unloading bulk materials from bunkers into pneumatic transfer systems, for example, pneumatic vacuum systems, and can be used in the chemical, mining, construction and other industries.

The purpose of the invention is to increase the stability of the composition of the pneumatic mixture and reduce the flow of compressed air.

The drawing schematically shows the proposed device.

It consists of a bunker 1, to the lower flange of which is attached a case 2, in which a platform 3 is fixed under an outlet of the bunker, mounted on springs 4. On a platform concentrically mounted in an outlet aperture 5 of it, to the upper part of which is located The conical divider 6 is attached. The conical divider can also be installed on the springs 7. The lower part of the string passing through the transport pipeline 8 ,. provided with a vibrator 9, telling it vertical oscillations.

The device works in the following way.

The bulk material from the hopper 1 flows through an outlet from a vertically oscillating, uus platform 3, is poured over the edge of the platform, and then enters the transport conduit 8, where it mixes with air, to form a pneumatic mixture. The bulk material in the arching zone in the bunker 1 is vibrated by the vibrating conical dissector and the springs 7 fastening it, as well as in the area of the outlet orifice, resulting in unobstructed

funnels, and from the outlet. The movement of the material occurs evenly, in a continuous flow over the entire cross section of the hopper 1. There are no parasitic oscillations of the platform 3 and the conical dissector, since they are fixed on the springs 4 and 7, the transverse rigidity of which is much greater than the longitudinal. The adjustment of the composition of the pneumatic mixture can be carried out by changing the gap between the lower cut of the outlet and the upper edge of the platform 3, as well as by changing the oscillation frequency of the vibrator 9.

Claims (2)

1. A device for injecting bulk material, mainly into a pneumatic conveying installation, containing a hopper with an outlet, in the lower part of a platform suspended elastically beneath it, concentric 0 a conical divider mounted inside the bunker with the top facing upwards and a vibrator rigidly connected to the platform, the latter of which is mounted outside the bunker, characterized in that, in order to reduce the flow rate of compressed air and increase the stability of the pneumatic mixture composition by increasing the uniformity of flow, the device is equipped with a vertically installed thrust, by means of which a rigid connection is made between the mentioned plates of the form, the vibrator and the conical dissector, the conical divider being mounted on the Khnemu end rod passed through the outlet of the hopper, a vibrator - at the lower end thereof, and the platform is arranged between the conical divider g and a vibrator. 2. A device according to claim 1, characterized in that the conical divider is elastically connected with the inner surface of the hopper.
