Description

The invention relates to the production of thermal insulation building products, mainly mineral wool semi-cylinders with a protective sheath.

According to the main author. St. No. 815003 is a known device for the manufacture of heat insulating products, comprising a hopper with a grinding mechanism, a mineral wool carpet forming unit, a heat treatment chamber and a pressing piston interacting with the forming unit, the latter being made in the lower part of the bunker open at the top. receiving chamber with a perforated bottom and a perforated bale chamber connected to it, which abuts the heat treatment chamber. C The disadvantages of the known device are with the impossibility of making thermal insulation products profile with a protective sheath as well as high energy consumption and heat loss with care gases.

The purpose of the invention is to enable the manufacture of core products with a protective sheath and reduce energy costs.

This goal is achieved by the fact that the device for the manufacture of heat insulating products is equipped with an assembly installed behind the heat treatment chamber for applying a plastic mass to the surface of the product and its curing chamber with a heat transfer agent inlet pipe connected to the chamber suction outlet pipe.

10 heat treatment.

At that, the unit for applying the plastic mass is made in the form of a bunker with a KOHycHbJM bottom, having a cut-out in the shape of a half-cylinder, and pressing a -1-1th chip, perforated bale chamber, heat treatment chamber and curing chamber of the plastic mass have a half-ring farm in cross section.

Claims (2)

The device consists of a melting unit 1, a fiber-forming mechanism 2, X1 of measure 3 of fiber deposition. conveyor 4 for supplying mineral wool carpet, bunker 5 with a mineral wool carpet grinding mechanism for press flakes b with a half-ring section, open receiving chamber at the top with a perforated bottom connected to a suction-foot patch that expands along the movement of the perforated 1 / press press carpet chamber 9 with a cross-section in the form of a half ring, the continuation of which is also a perforated heat treatment chamber, equipped with nozzles 10 and 11 of the supply and removal of the heat transfer fluid and consisting of a zone 12 of surface hardening from the zones 13 of the polymer binder, node 14 for applying a plastic mass to the surface of the product, in which the plastic mass container has a conical shape, chambers 15 for curing the plastic mass equipped with a heat transfer inlet pipe 16 connected to the heat treatment chamber from the heat carrier 11, a nozzle 17 for withdrawing the coolant from the chamber 15 for curing the plastic mass and the cutting mechanism 18. The device works as follows. The melt flowing out of the smelter of the aggregate 1 is processed into the fiber by the fiber-forming mechanism 2. In the fiber deposition chamber 3, a binder solution in the amount of 4-5% (counting on the mass of dry material) is deposited on the fibers and precipitated as carpet on transport Tere 4, which feeds the carpet to the hopper 5 with a carpet chopping mechanism for flakes. Shreds of the Wool are sucked in by the air flow into the body of the perforated press chamber 9 and at the same time have an arbitrary orientation. The air is sucked through the perforation of the press chamber 9 by the suction nozzle 8. Press 6, moving back and forth, seals cotton wool scraps in press chamber 9 and pushes the formed mass, in the form of a half cylinder, into the heat treatment chamber. The implementation of the press chamber 9, expanding along the formed mass, relieves the volumetric stress state in the molded mass that occurs during the molding process, reduces the trencher forces and the bulk weight of the finished distance. In order to consolidate the geometric shape and reduce frictional forces while advancing the molded mass in the zone 12 of the heat treatment chamber, curing on the surfaces is carried out. The coolant supplied through the pipe 10 is blown through the mineral wool mass in zone 13 and provides the binder polymerization throughout the thickness of the article. While advancing through zones 12 and 13 of the heat treatment chamber, the formed mineral-cotton mass continuously adheres to the walls of the chamber, thus excluding heat carrier flow in addition to the mass. From the heat treatment chamber, the semi-cylinder enters the node of the chamber 14 for applying a plastic mass to the surface of the semi-cylinder. In the curing chamber 15, heat treatment of the protective sheath is carried out using a heat carrier coming from the heat treatment chamber through the pipe 16. The spent heat carrier is ejected through the pipe 17. The cutting mechanism 18 cuts off the half-cylinders of the desired length. The proposed device makes it possible to manufacture heat insulating products with a protective sheath, which makes it possible to increase labor productivity in the installation of heat insulating pipelines by reducing the amount of work associated with insulating the device in a protective sheath. The use of the heat carrier from the heat treatment chamber in the solidification chamber makes it possible to reduce the temperature of the emitted gases to 60–70 ° C (in known installations, the temperature of the emitted gases is 120–160 ° C). Claim 1. Arrangement for the manufacture of thermal insulation products according to author. No. 815003.0 in order to ensure that it is possible to manufacture profile products with a protective sheath and reduce energy consumption, it is equipped with a unit installed behind the heat treatment chamber for applying a plastic mass to the surface of the product and its curing chamber with a suction inlet pipe pipe heat treatment chamber. 2. The apparatus according to claim 1, characterized in that the unit for applying the plastic mass is made in the form of a hopper with a conical bottom having a cutout in the shape of a half-cylinder, and the pressing piston, the perforated pressing chamber, the heat treatment chamber and the above-surface plastic mass chamber have cross section shape of a half ring.
