Description

-1 g &

The invention relates to the construction and building materials industry, namely to installations for the preparation of polystyrene concrete.

The purpose of the invention is to increase productivity, reduce energy consumption and save polystyrene.

The drawing shows the installation diagram.

The installation contains a frame (not shown), a cement tank 1 with a continuous batch 2, a bead polystyrene hopper 3 with a batcher 4, a boiler-foam 5, a hopper 6 foam polystyrene with a batcher 7, a system of pneumatic transport of components with a compressor 8, a receiver 9, pipelines TO 11.11, tank 13 for water or an aqueous solution of chemical additives and mixer 14.

Boiler blowing agent 5 is made with two skins, between which a layer of thermal insulation material (not shown) is laid. A coil 15 is welded to the inner lining, for example, having a section 16, attached to a polystyrene bead supply pipe to the boiler 5. The coil 15c, section 16, is connected by supplying 17 m return 18 pipelines through a pump 19c to the heating medium heating tank 20, such as oil.

The coil 15 is at the same time the ribs of the boiler 5.

The oil heating tank 20 is equipped with a thermostatically controlled heating device and is installed inside the water heating tank 21,

The latter is also provided with a heating device with a thermostat and is connected by pipelines 22, 23 via level control valves, respectively, to a water tank 13 and to a frothing boiler 5.

The water tank 13 is connected via a valve regulator to the level from the water pipes and through the pump 24 by a pipe 25 to the mixer 14.

Boiler-blowing agent 5 communicates with the bunker 6 of foamed polystyrene, the walls of which are perforated, with a cavity 26 between the walls and the heat insulating casing of the bunker 6. The air cooling system of the compressor 8 is connected by a pipeline 27 through the fan 28 to the cavity 26 of the bunker 6.

A water tank 13 is placed in the upper part of the heat insulating casing of the bunker 6 with a gap relative to its walls.

The oil heating tank 20 is installed in the water heating tank 21 with the possibility of vertical movement along the guides and is equipped with a lifting mechanism (not shown) that is driven by a temperature controller of the heating device of the water heating tank 21.

The installation is equipped with a remote control 29 controls.

The installation works as follows.

Heated to 98-99 ° C water continuously

0 is supplied from tank 21 through a level regulator valve to a blowing agent 5.

In the coil 15, 16, the oil circulates heated to 110-120 ° C, heating the inner skin of the boiler 5 and the bi5 pipeline for sulfur polystyrene.

From the hopper 3 through the dispenser 4 through the heated pipeline, bead polystyrene continuously flows into the foaming boiler 5, falls into boiling water, rises to the surface as it foams, and then rises to the vapor medium above the water mirror where it flows.

Polystyrene pellets are fed into the bunker 6. where through the pipeline 27

5 is continuously pumped by the fan 28 through the cavity 26 and the air heated to 40-50 ° C from the air-cooling system of the compressor 8. As a result of blowing hot air, the granules acquire elastic

0 properties that prevents their shrinkage when mixed in the mixer.

After blowing granules of foamed polystyrene, heated air enters the cavities between the heat insulating casing and

5 by the walls of the tank 13 for water, heats the water in it and then cooled air is discharged through the holes in the cochlea into the art sphere.

From the tank 13, the water is fed through the level control valve to the tank 21, where it is additionally heated from the walls of the oil heating tank 20, and also, as necessary, by a heating device with a thermostat.

5The required temperature of heating water in

tank 21 is provided as follows. When the temperature reaches 99 ° C, the thermostat turns off the pump | The ataic device, when this temperature is exceeded (for example, due to more intensive heating of water in the tank 13. at elevated ambient temperatures), the thermostat activates the lifting mechanism of the oil heating tank 20, thereby reducing the heating back temperature in contact with the water in the tank 21 .

Polystyrene foamed and treated with nagging air from storage hopper 6 through dispenser 7 through conduit 12 enters mixer 14. into which it is simultaneously supplied to a tinder from tank, 1 through dispenser 2 and water from feed tank 13 through conduit 25 through pump 24 (or chemical additive solution).
