INSTALLATION FOR PREPARING A NON-AUTOCLAVAL

The proposed utility model relates to the building materials industry and is intended for the preparation of foam concrete, from which blocks are made for the construction of residential, public, industrial and agricultural buildings, heat-insulating blocks for partitions, heat and sound insulation of roofs, floors, as well as monolithic structures.

The closest technical solution to the proposed one is an installation for preparing and transporting a cellular concrete mixture into the formwork, containing a container with compartments for pre-mixing the components of the mixture, in particular for mixing water with chemical additives, and for final mixing of the cellular concrete mixture, after which the finished mixture is pipelines served to the place of manufacture of finished products (RU No. 2027833 C1, 1995.).

A disadvantage of the known installation for the preparation of the mixture is the impossibility of obtaining finished products with high heat and noise protection properties.

The objective of the proposed technical solution is the manufacture of finished products from non-autoclaved foam concrete in the form of blocks or monolithic structures with the required strength, high heat and

soundproofing properties, as well as reduced consumption of astringent

This object is achieved in that the installation for the preparation of non-autoclaved foam concrete includes a foam mass preparation unit comprising a water pump connected to each other by means of pipelines with shut-off valves, one or more parallel-connected containers for preparing an aqueous foaming solution and a foam generator connected to the compressor, and a foam concrete preparation unit, containing a bin for cementitious material, which is used as cement, a bin for mineral filler, nap Emer sand or other similar material, with the boot barosmesitel neck and a lid coupled to the compressor and a foam generator.

The bar mixer and the foam generator can be connected to a common compressor.

The cement hopper is equipped with a feeder, for example a screw, preferably with a rotary chute for supplying cement to the bar mixer, and the sand hopper is equipped with a skip elevator and a feeder, for example, tape, with a rotary chute for feeding sand to the bar mixer.

The installation for the preparation of non-autoclaved foam concrete is illustrated by the drawing shown in FIG.

The installation comprises a foam mass preparation unit and a foam concrete preparation unit installed in a technological sequence. The foam preparation unit 1 consists of, preferably two, connected to the water pump 2 and between them by pipelines 3 with shutoff valves 4, containers 5 for preparing an aqueous solution of a foaming agent in them, and a foam generator 6. The assembly 7 for preparing foam concrete consists of a hopper 8 for cement equipped with a feeder 9 and a rotary estrus 10, a hopper 11 for sand, equipped with a skip hoist | com 12, feeder 13 and rotary estrus 14, bar mixer 15 with loading neck 16 and cover 17, and compressor 18, which is connected via pipelines to bar mixer 15 and foam generator 6.

The installation for the preparation of non-autoclaved foam concrete works

in the following way.

The technology for preparing foam concrete includes two main operations: first, partial porization of the raw mix is carried out, and then its final porization in a bar mixer at an overpressure. The transportation of the prepared foam mass is carried out using compressed air through a solution pipeline.

Before starting work, the cement truck is filled in with a cement 8, and the hopper 11 with a skip hoist 12 with sand. Then the containers 5 are filled with water, the calculated amount of the foaming agent is added, the water pump 2 is turned on, the foaming agent solution is thoroughly mixed, the compressor 18 is turned on, and through the foam generator 6 the aqueous solution of the foaming agent in the form of foam is fed into the mixer 15 with the drive of the shaft 19 turned on. After filling the mixer with the required amount of foam using the feeders 9 and 13 and rotary leaks 10 and 14, a predetermined amount of cement and sand is fed into it to obtain the estimated density of the foam concrete, close the lid 17 and p Under the pressure of the air supplied from the compressor 18 through the mortar line 20, the foam concrete is squeezed out of the mixer to the molding site.

The strength of finished foam concrete products is increased by 10-20%, thermal conductivity is reduced by an average of 15%, and the consumption of binders is reduced by 15-25%. Thermal insulation blocks have high soundproofing properties and can be used for interfloor ceilings, roofs of partitions and products of similar purpose.
