SU1310224A1 - Gravity mixer - Google Patents

Description

The invention relates to the construction and production of building materials, namely to devices for preparing building mixtures.

A device for mixing building materials is known, which contains a drive drum, on the inner surface of which the working bodies are fixed by means of brackets in the form of chain segments.

A disadvantage of the known device is the low intensity of the mixing process, due to the small number of zones of active influence of the working bodies on the components of the mixture.

Closest to the present invention is a gravity mixer, containing a housing with a loading and unloading nozzle, a mixing body in the form of springs and devices for feeding the mixture into their interturn space.

However, the known device is characterized by an insufficient intensity of the mixing process, due to the impossibility of supplying the mixed materials into the interturn spaces of the spiral-shaped elements and the vibrational movements of these elements.

The purpose of the invention is to intensify the mixing process.

This goal is achieved by the fact that in a gravitational mixer containing a body with loading and unloading nozzles, a mixing body in the form of springs and devices for feeding the mixture into their interturn space, each device for feeding the mixture into the interturn space of the spring bucket blade to

the tray part of which is rigidly fixed end of the spring.

In addition, the mixer can be equipped with unbalances in the form of weights, by means of which the springs are interconnected in the middle part.

FIG. 1 shows a gravity mixer, general view; in fig. 2 shows section A-A in FIG. one.

The gravitational mixer contains a drive drum 1, a moving member in the form of helical springs 2 with weights 3 in their central part and buckets of blade 4 fixed to the inner surface of the body. The ends of the helical springs are rigidly fixed to the tray parts 5 of the bucket blades. The initial components are loaded and the finished mixture is discharged through pipe 6.

The mixer works as follows.

The components of the mixture are loaded into the drive drum 1 through the nozzle 6, the drum is turned on, which is intensively mixed with helical springs 2, and the mixture is lifted by the blade-shaped blades 4, the tray parts 5 of which dump the mixture into the interturn spaces of the springs, communicating kinetic energy and forcing, together with the load batteries 3, to make oscillatory movements with a large amplitude and frequency. Unloading of finished products is carried out through the pipe 6.

The proposed implementation of the mixer allows to significantly intensify the mixing process, to improve the quality of concrete mixes and to obtain mixtures with a lower water-cement ratio.
