SU130329A1 - Continuous multi-drum vibratory mixer for preparing hard concrete mixes - Google Patents

Description

The invention relates to multi-drum continuous vibration mixers for the preparation of rigid concrete mixtures, the drums of which are arranged in three rusas and are connected by the riverrush material-carrying sleeves, the drum located in the lower rusa being mixing and the drums of the upper rushes are dosing for the components. The drums are equipped with vibration-rotatable structural elements contributing to the processes occurring in the drums.

Known mixers of the same kind are not adapted for continuous dosing of components, and, moreover, they do not provide self-removal of the mixture sticking to the walls.

In the described mixer, these shortcomings are eliminated by the fact that the vibration-rotating elements of the upper drums are made in the form of screws, and the rotary element of the lower drum is in the form of a cylindrical frame made up of horizontally, straight and transverse annular ribs made of metal of an angular profile, facing both longitudinal edges to the walls of the mixing drum.

FIG. 1 shows a mixer, side view with a partial cut; in fig. 2 is the same, view along arrow A in FIG. 1.

The drums of a continuous vibration mixer, intended for the preparation of rigid concrete mixtures, are located in three rus. The drum 1, located on the bottom floor, is a mixing drum; inside it is freely located an element rotating under the action of vibration, made in the form of a cylindrical frame No. 130329-2 kasa 2. The frame 2 is made up of longitudinal straight shelves 3 and transverse annular ribs 4. The shelves 3 are made of metal of an angular profile, facing both longitudinal edges stakes of the mixing drum, which contributes to the successful removal of the concrete mixture sticking to them from the walls. The drums 5 of the upper rus are designed for continuous dosing of the O-components coming from the bunkers, and inside them there are freely rotating elements vibrating under the action of vibration, made in the form of augers 7, which provide high accuracy of dosing.

The drums are interconnected by the conductive material-carrying sleeves S, and with the hoppers 6 by means of sleeves 9. The sleeves are made of elastic material.

Subject invention

A continuous multi-drum vibratory mixer for preparing rigid concrete mixes, the drums of which are arranged in three rus and are connected along an fi rst material conduit with shimch sleeves, the drum located in the lower rus is the mixing one, and the drums of the upper rus are dosing for components, and in all the drums of which there are elements rotating under the action of vibration, characterized in that, for the purpose of continuous dosing of components, mixing of rigid concrete mixture and removal from the walls the araban of the lower russia of the sticking mixture, rotating under the action of vibration, the elements of the upper drums are made in the form of augers, and the rotating element of the lower drum is made in the form of a cylindrical frame made up of longitudinal and transverse annular ribs made of metal of an angular profile, facing both longitudinal edges to the walls of the mixing drum.
