MACHINE COMPLEX FOR POLYSTYRENE CONCRETE ARTICLE PLANT Russian patent published in 2007 - IPC B28B15/00 

FIELD: building material production, particularly working stone, clay or cement, namely to produce polystyrene concrete articles (blocks, slabs and beams).

SUBSTANCE: machine complex comprises expanded polystyrene filler production equipment including bins with foaming polystyrene stock, foaming device, supply bin for secondary polystyrene foaming and aging bins. Machine complex also has concrete mixing equipment including proportioning bins for materials used for polystyrene concrete mixture preparation and concrete mixer, as well as conveyer equipment. Conveyer equipment comprises main belt including concrete placer, finishing device, electric molds made as buggies with drop sides, electric-and-heat treatment stations to accelerate polystyrene concrete hardening. Electric-and-heat treatment stations are made as vertical thermal packs of electric molds with shaped polystyrene concrete articles of mass. Conveyer equipment also comprises end belt including article containerization devices, which pack and transport ready articles to storehouse. Expanded polystyrene filler production equipment comprises device for stepped ecological gas-vapor-air emission purification. Concrete mixing equipment comprises volume proportioning means for foamed polystyrene concrete filler and milled expanded polystyrene plate waste, receiving storage bin and proportioning means for expanded polystyrene powder obtained during polystyrene article sizing or during nonstandard polystyrene article milling, receiving bin and proportioning device for tailings obtained during polystyrene concrete mass sawing, steam generator with foam proportioning pump, proportioning bin for additive, namely polystyrene concrete mix detoxifier, proportioning bins for modifying agents and water, as well as vertical, horizontal or gravity concrete mixer. Main conveyer equipment comprises electric molds for non-reinforced or reinforced polystyrene concrete mass forming. Non-reinforced polystyrene concrete mass has dimensions of (1.2-4.0)×(0.6-2.4)×(0.3-0.9) m and may be cut into blocks, plates and complementary units. Reinforced polystyrene concrete mass has dimensions of (1.2-3.0)×(0.6-2.4)×(0.2-0.3) m and may be cut into reinforced beams. Main conveyer equipment also includes locking mechanisms for electric mold sides opening or closing, device for mechanized cleaning and lubricating of shaping surfaces of electric mold, mechanical pusher, which pushes off hardened polystyrene concrete mass from electric mold, cutting device for hardened polystyrene concrete mass cutting into blocks, plates, beams and similar items having predetermined design dimensions in longitudinal and transversal directions with the use of mechanical water-cooled saws, mechanical electric molds stacker, which creates thermal packs, sizing device, which imparts predetermined height to polystyrene concrete blocks and plates and is provided with water-cooled sizing mills and handling crane for electric mold movement to electric-and-heat treatment stations and from the stations. Conveyer end belt equipment comprises receiving boggy, ready article stacking means, mechanical wooden tray accumulator to accumulate trays for article stack supporting, packing device and apron conveyer to transport wooden trays for article stack laying place. Ready article stacks are placed in wooden trays and packed stacked articles are conveyed to storage facility. Utilization equipment performs utilization operation by adding tailings obtained during massif sawing, polystyrene concrete powder generated during block sizing, nonstandard polystyrene concrete article milling and milled expanded polystyrene article waste in polystyrene concrete mix. The utilization equipment comprises tailing accumulation sump provided with submersible pump, tailing basin, pneumatic pump to supply tailings to receiving bin of concrete mixing equipment via tailing pipeline, mill for nonstandard polystyrene concrete article milling, polystyrene powder receiving vessels, automated lifting-and-transportation mechanism for vertical vessel movement and polystyrene powder unloading into receiving storage bin in concrete mixing equipment, mill for plate polystyrene waste milling and pneumatic transport system for milled material supply into bin of volumetric proportioning means of concrete mixing equipment.

EFFECT: increased ecological safety of polystyrene concrete article production and usage, decreased production costs, increased mechanization and automation level and labor productivity, increased fullness of polystyrene concrete article quality and possibility of full production waste utilization along with decreased material consumption for article production, extended polystyrene concrete article assortment and increased number of produced articles per production space unit.
