Description

The invention relates to the construction and can be used for the preparation of concrete mix.

A known installation for preparing a concrete mix, containing a skeleton, consumable bins for cement, fill-ups and water, metering devices connected to the loading mechanism with mixers with its swivel funnel, inside which are introduced guide lines for feeding aggregates, as well as pipelines for feeding cement and water, divider, pipe with tray and ready mix dispensers 1.

The disadvantage of the device is low productivity due to the low efficiency of mixing the components entering the funnel during their loading into the mixer.

The purpose of the invention is to increase productivity by increasing the efficiency of mixing the components entering the funnel during their loading into the mixer.

The set ue; ib is achieved by the fact that in unit e, 1 of the concrete mix preparation, the axis of each cement pipeline introduced into the rotary funnel is located at an angle of 3-30 ° to the plane passing through the vertical axis of the funnel and the vertical axis of the corresponding the pipeline or guide, and the discharge ends of the cement supply lines are directed in the opposite direction relative to the discharge ends of the loading lines for aggregates.

FIG. 1 shows a plant for preparing a concrete mix, a general view; in fig. 2 - turnable funnel, general view; in fig. 3 is a view A of FIG. 2

The installation contains a frame 1 c) with cement cement bins 2, aggregates 3 and water 4, each bin through appropriate dispensers 5, 6 and 7 are connected via loading mechanism 8 with mixers 9. The loading mechanism has a swivel funnel 10 into which guides are inserted 11 d; 1 filler feed, as well as pipelines 12 and 13 for cement and water feed At the free end 14 of the pipeline 13, located in the center

and above the ends. 11 and piping 12, a spreader 15 is installed, and the free end of piping 12 is located below the guides 11. The axis of each pipeline introduced into the swirl funnel 10 for cement 12 and the guides 11 for aggregates is located at an angle of 3-30 ° the vertical axis of the funnel and the axis of the vertical section of the corresponding pipeline or guide, and the discharge ends of the pipelines 12 for feeding cement are directed in the opposite direction relative to the discharge ends of the guideways 11 for the aggregate d. The funnel 10 is connected through pipe 16 and tray 17 with

mixers 9, installed above the hoppers for dispensing the finished mixture 18.

The installation works as follows.

Cement, aggregates and water flow from bins 2, 3 and 4 to the corresponding metering units 5, 6 and 7. When the metering unit is unloaded, the material along the guides 11 and pipelines 12 and 13 is sent to the funnel 10 of the loading mechanism 8. Water flows to the divider 15 and sprays, creates a5 a water curtain from dust and wets the material that captures the cement coming out of the pipeline 12, the guides 11 and the pipelines 12 for cement being placed at an angle to the plane passing through the funnel vertical axis

0 10 and the axis of the vertical section of the corresponding pipeline or guide, as well as the installation of the discharge ends of the guide 11 towards the discharge ends of the pipelines 12 for cement, provides intensive mixing

5 aggregates with cement as they pass through the funnel 10. The pre-mixed mixture through the nozzle 16 and the tray 17 enters the corresponding mixer 9. After mixing, the concrete mix is discharged into the hopper 18 and the cycle repeats.

The use of the plant allows to increase the productivity of concrete mix preparation and to improve the quality of the prepared mix.
