Abstract

The invention relates to vibromixers and allows for improved operating conditions and reduced material loss. The vibratory mixer contains a housing mounted on the shock absorbers associated with the vibration exciter and having a hole in the bottom with an external clearance. It is equipped with a solid plate located above the outlet. The angle lying in a vertical plane and enclosed between the horizontal and the line drawn through the lower edge of the edge of the plate and the upper edge of the outlet, is less than the angle of repose of the material. 1 il.

The invention relates to vibro-smudders and can be used to mix bulk materials in the powder metallurgy, chemical and other industries.

The purpose of the invention is to improve the operating conditions and reduce the loss of material.

The drawing shows a vibrometer, a general view.

The vibratory mixer contains a vibration exciter 1, a working chamber 2 and a counterweight 3, interconnected by a crosspiece 4 supported on frame 5 through 15 shock absorbers 6. Working chamber 2 is equipped with a loading / rest 7, a through hole 8 with a gate 9 and guide vanes 10, other devices, for example, the wavy bottom of the working chamber, etc. A solid plate 11 is fixed above the outlet opening 8 by means of replaceable spacer sleeves 12 and nuts 13 on rods 25 in x 14. The plate is reinforced so that the angle lying in a vertical plane and enclosed between the horizontal and the line through the bottom edge of the solid plate 11 and 30 the upper edge of the outlet 8, less than the angle of repose of the material jB. Rods 1A are welded to the bottom of working chamber 2 or creet pa la cha pl pa st not sy more

By this, a small part of the material is poured out through the outlet opening, enclosed in the space between the part of the lower surface of the solid plate 11 and the shutter 9, and circumferentially bounded by the surface of the showered material at an angle of repose. After elimination of the malfunction, the shutter 9 is closed, the poured material is returned to the working chamber through the charging port 7.

After the mixing is completed, the shutter 9 opens, and with the exciter running, the material through the gap between the solid plate 11 and the bottom of the working chamber 2 flows into the outlet 8 due to fluidization of the material and, accordingly, reduction of the angle of repose during vibration.

When changing brands of materials to be mixed, in some cases it is possible to increase the angle of repose and, accordingly, decrease the rate of material outflow through the gap between the solid plate 11 and the bottom of the working chamber 2. . This embodiment of the vibromixer allows you to maintain the slit width in the maximum allowable dimensions and thus

start-up of the finished material from the vibromixer.

In this case, on each side of the hole 835, the maximum speed of the mixer is as follows.

When the shutter 9 is closed, the components of the material being mixed are poured into the working chamber 2 through the loading hatch 7, after which the hatch is closed. When the vibration exciter 1 is in operation, circular oscillations are connected to the working chamber 2, under the action of which the material circulates inside it.45

In order to increase the mixing efficiency, guide blades 10 or other devices, such as a corrugated bottom, etc., are usually installed inside the working chamber 2. ,50

When a valve 9 leaks, which is manifested in material leakage and drinking, is detected, the vibration exciter stops and opens the valve 9 to eliminate the malfunction. At 55
