RU13382U1 - MINI-FACTORY CONTAINER TYPE FOR THE PRODUCTION OF DRY CONSTRUCTION MIXTURES - Google Patents

Description

Container-type dry-mix mortar mini-factory

The utility model relates to the field of construction, namely to the production of ready-to-use (with the addition of water) dry mixes for installation, masonry, plastering, plastering, tiling and other works.

Currently, in the construction business in Russia, dry mixes are used, produced either in imported factories or in semi-artisan installations. At the same time, the demand for dry mixes is constantly growing, capturing more and more new regions of the country. The most developed region of Russia in the production of dry building mixes (CCC) is the city of Moscow. Their annual consumption here is about 200 thousand tons or about 20 kg per inhabitant. The needs of the city are satisfied today due to the factories built 15 years ago by the Finnish firms Lohja and Feksima in the cities of Shchelkovo, Vidnoye and also in Moscow itself (Biryulevo and Kapotnya). Other regions of Russia in relation to the consumption of CCC are offomic white spots. For comparison: in Germany, about 80 kg of dry mixes are produced per person per year, in Finland and Sweden - 60 kg, and in Russia - about 3 kg. In Moscow, this figure is 20 kg, and judging by the steady increase in the supply of CCC in the capital, this value is far from the saturation volume. However, at a distance of more than 50 km from the city, the availability of dry mixes drops to 5-6 kg per 1 person. per year or less.

The closest analogue to the proposed one is a plant for the production of dry building mixtures, containing a hopper compartment with a receiving chamber, a system of horizontal and vertical augers, a grinding device and prefabricated chambers (RU 2027831, E04G 9/00, 1995).

The disadvantage of the analogue is the unjustifiably large volume of the installation, due to the irrational combination of transport systems in the design.

The technical result of this utility model is to reduce the total installation volume by a rational combination of transport systems in the design, to create a domestic compact fast-mounted mini-plant of container type for the production of dry building mixtures, which is able to displace imported equipment of this type from the Russian market of the construction industry.

dry construction mixtures, containing a hopper-hopper compartment with a receiving chamber, a system of horizontal and vertical augers, a grinding device and prefabricated chambers, according to the claimed utility model, equipped with a loader, a vibrating screen located behind the loader, a conveyor for supplying raw materials, a dryer, an elevator connected to a vibrating screen, the capacity of the finished mixture, connected to the filling machine, the dispenser on the one hand connected to the hoppers of fine and coarse sand and a binder reagent through screw feeders, and on the other sides - with the capacity of the finished mixture through the mixer.

The technical result is optimally achieved under the following conditions:

-used pofuzchik in the form of a feyfer;

- the dryer is made in the form of a drum with laughter;

-installation is equipped with a conveyor belt connected to the filling machine.

Thanks to the use of the complete-block design of the mini-factory and the manufacture of blocks (containers) with technological equipment in full factory readiness with a control assembly at the manufacturer, its installation on prepared for storage of cementing foundations and concrete platform and commissioning is carried out within 10- 12 shifts.

Installation of the mini-factory at the place of operation consists in assembling completely finished blocks and making joints of the suction pipes on the flanges, as well as in connecting the plug connectors of the electrical circuits.

The container-type mini-plant is intended for the preparation of dry mortar mixes using unfractionated sand with a moisture content of up to 10% .j

The MZS-10 mini-plant is equipped with an automatic control system at the modern technical level using tensometric metering equipment and microprocessor equipment.

The automatic control system provides for the issuance of a printed passport for each batch of the prepared mixture with an indication of the formulation, as well as indicators for taking into account the consumption of components and the amount of the mixture issued.

With the basic configuration of the equipment, the mini-plant of dry construction mixtures with a capacity of 10 thousand tons per year (MZS-10) will be able to produce the following main types of dry mixes:

The container-type mini-factory for the production of dry construction mixtures is a new word in construction equipment and is competitive with the best examples of domestic and imported equipment of this profile. The complete-block principle, which allows transferring the adjustment process to the stationary conditions of the manufacturer, instead of conducting it in unsuitable conditions at the customer, was not implemented before the proposed utility model for the production of dry building mixes in either domestic or foreign practice. After the control assembly and commissioning at the manufacturing plant, the finished plant is disassembled into container blocks, transported by container ships and assembled at the customer’s prepared site for several (no more than 12) work shifts.

The obvious advantage of the installation created is its compactness, which was achieved due to the successful combination of vehicles in the plant system (belt conveyors, chain bucket elevator, screw conveyors). A rational combination of modes of transport allowed to reduce the construction volume of the mini-plant by 2 times in comparison with analogues and significantly reduce the height of the plant. Successfully applied drum dryer of domestic design, not inferior to the best foreign models. It was possible to completely avoid the installation of buried foundations for the equipment of the mini-factory, which allowed minimizing the construction operations preceding the installation of the modules of the mini-factory.

Duplication of the production of sets of equipment for containerized mini-factories will be the most important result of creating the proposed utility model of a mini-factory for the production of dry building mixtures. To meet 50% of the needs of the construction complex in Russia (3 million tons per year), 150 such enterprises can be built. The annual production of dry mortar on them will be 1.5 million tons.
