Description

The invention relates to equipment used in the construction of various structures of concrete mixes.

The purpose of the invention is to simplify the design, reduce the energy intensity and increase reliability.

Fig. 1 schematically shows a deep vibrator for compacting concrete mixtures, a general view in section; FIG. 2 is a section of A-Ana of FIG. one; on fig.Z-section bb in figure 1.

A planetary immersion vibrator for compacting concrete mixes consists of a hollow cylindrical body 1 placed in its cavity 2 with a gap of a cup 3 slider with a support lug 4 on the bottom, in which tangential channels 5 are formed at an acute angle and tightly closed. a cap 6, having a central bore with a spiral labyrinth seal 7, in which an air inlet fitting 8 is placed, connected by a flexible hose 9 to a pressure source (not shown) and resting the bottom to with a protrusion 10 and a through radial inclination 11 connected to the longitudinal channel 12, on the centering recess 13 in the bottom of the glass 3.

Planetary immersion vibrator works as follows.

Compressed air supplied through a flexible hose 9 and fitting 8 into cavity 2 when flowing out of tangential channels 5 creates the main torque with a reactive action of its jets in the form of a cup 3, and since channels 5 are made down at an acute angle, this reactive

the action of the jets together with the torque creates a lifting force that separates the cup 3 from the bottom of the body 1 and abuts its recess 13 into the fitting 8, eliminating the parasitic forces of friction of the ends of the glass 3 against the body 1. Due to the torque, the glass 3 rotates around its vertical the axles and rolls along the lateral surface of the cavity of the housing 1, causing in the latter vibrational oscillations generated in the concrete mix, which under their action condenses. After expiring through the gap between the fitting 8 and the lid 6 by the spiral cutting of the seal 7, the compressed air creates an additional torque 3 for the glass 3, which coincides in direction and is summable with the main one. Invention Formula A planetary immersion vibrator for compacting concrete mixes, comprising a cylindrical body placed in the latter and a hollow slider contacting with its inner surface, enclosing an air inlet connection connected by a flexible hose with a pressure source, characterized in that, in order to simplify the design, to reduce the specific energy and increase reliability, the hollow slider is made in the form of a glass with a support protrusion on the bottom in which tangential channels inclined at an acute angle are formed s lid having a central aperture with a spiral labyrinth seal for receiving the fitting.
