Description

Universal mini concrete and foam concrete plant is intended for use in the construction industry. In particular, for the continuous production of foam concrete and concrete, and for supplying the finished mixture to construction sites.

The mobile concrete mixing plant MobilSmes BMX-26M is known, developed by the scientific and production center Block Modular Design Systems of the 26th Central Research Institute of the Ministry of Defense of the Russian Federation (copies of prospectuses are attached). This modular installation is designed for cyclical preparation of concrete. The basic module includes the following blocks:

- block of inert hoppers, including unloading cone, two-component dispenser, compressor.

- a unit for dosing cement and water, including dispensers for cement and water and chemical additives.

- a mixing unit, including a cyclic concrete mixer series BSM26, a receiving funnel, an unloading tray.

The supply of ingredients from one block to another is carried out by conveyors. Unloading of finished products is carried out by a 3-level conveyor-type loader. The disadvantages of the above installation are that the preparation of concrete is cyclical in nature, and the installation itself is intended for the preparation of only concrete, and cannot be used for the preparation of foam concrete. In addition, the considerable weight (up to 20 tons) and the large overall dimensions of the installation (transported in four containers) make it difficult to deliver a set of block modules to the place of operation.

The proposed universal mini concrete and foam concrete plant (UMB) is designed for continuous preparation of both concrete and foam concrete with significantly smaller overall dimensions and weight compared to the prototype. This goal is achieved by installing instead of one large cyclic concrete mixer three (or more) compact baromixer-superchargers working in series. Bar mixers are loaded with ingredients using special assembly and distribution conveyors. Transportation of the mini plant to the place of operation is carried out in two containers.

Figure 1 shows the device of a universal mini plant and its layout. Figure 2 shows the device of the mixer-supercharger, where: 1 - drawer feeder, 2 - conveyor bucket, 3 - horizontal and vertical guide beams of the conveyor bucket, 4 - feed hoppers, 5 - ingredient dispensers, 6 - assembly conveyor, 7 -distribution conveyors, 8 - loading hatch, 9 - mixer bar supercharger, 10 -

cement screw conveyor, 11 - compressor, 12 - control panel, 13 - armor plates, 14 - groove between armor plates, 15 - mixer bar body, 16 - flexible element with reversible deformation, 17 - mixer bar drive, 18 - discharge nozzle.

Universal mini concrete and foam concrete plant works as follows:

Using a vehicle, the box feeder 1 is filled with one or another ingredient. Using the conveyor bucket 2, moving along the vertical and horizontal rails of the guides 3, from the drawer feeder, they enter the corresponding feed hopper 4. Thus, all the hoppers are filled with the ingredients necessary, according to the technology, for the preparation of one or another type of concrete, or foam concrete. Ingredients are dispensed by dispensers 5 and poured onto the assembly conveyor 6, and from it are poured onto distribution conveyors 7, and through loading hatches 8 are loaded into baromixer-superchargers 9. The assembly and distribution conveyors are reversible. The cement is supplied to the bar mixers by a screw conveyor 10. Control of concrete and foam concrete parameters, as well as automatic (or manual) control of the mini-plant equipment, is carried out from the control panel 12. The discharge nozzles of 18 bar mixers are combined. Unloading of finished products is carried out by the pressure of compressed air supplied to the cavity of the mixer bar by compressor 11.

In the preparation of foam concrete, the ready-mixed concrete prepared by the mixer-blower is aerated by air bubbles entering the cavity of the mixer through the groove 14 between the armor plates 13. In the grooves are flexible elements with reversible deformation 16, in the walls of which a lot of micro-holes are made. In this case, rubber hoses are used as flexible elements.
