Description

Often, the invention relates to the production of heat insulating building materials and can be used in lines for the manufacture of perlite-fiber plates from hydromass.

The purpose of the invention is to increase the productivity and quality of products, reduce energy consumption and improve the purification of exhaust gases.

The drawing shows the proposed line, general view.

The production line contains a fiber component preparation unit, which includes a pulper 1, a magnetic separator 2, a vortex cleaner 3 pulps, grinding units 4, a pool drive 5, a pulp thickener 6, a homogenizer mixer 7, a pulp dispenser 9, an exfoliated unit perlite, including intumescent 10 and precipitating device 11, silo storage 12 and receiving hopper 13, expanded perlite dispenser 14, mixer 15, hydromass mass feeding and shaping unit 1b with subpressmaster 17, dewatering system 18, chamber 19 ter processing, assembly 2P cutting carpet with waste receptacle, economizer 21 and gas cleaning unit 22. In order to ensure that the fiber component passes through the grinding system multiple times, the storage pool 5 is connected by a return pipe 23 to the initial grinding unit D. To reuse the water separated in the thickener 6, it is connected to the pulper 1 by a return pipe 2k.

Boxes of the l8 dewatering system by pipelines 25 and 2b are connected respectively to the inlet of the heat exchanger of the economizer 21 and the hose of the humidifier of the wet gas cleaning unit 22, g the outlet of the heat exchanger of the economizer and the accumulator of the wet cleaning of gases using pipelines 27 and 28 are connected to a homogenizer mixer 7. For maximum use the heat, deposited in the swelling device 10, the exhaust branch pipe of the exhaust gases of the precipitating device 11, is MOTELING 11DIM collector 29 is connected to the chamber 19 processing, which is similar to the collectors 30 and 31 connected to unit 22 through the wet cleaner economizer 21.

The caused waste practically does not affect the quality of the produced fiber products, then to create waste-free production, the waste receiver of the cutting unit 20 is connected to the mixer-homogenizer 7 by the conveyor 32.

Flow line works as follows.

The starting components — paper or cardboard waste paper (or their mixture) and fractionated perlite — are respectively fed into the water-filled pulper 1 and the intumescent device 10. The pulp that is dispersed in hydro-distributor 1 is separated from the ferromagnetic and heavy particles by separator 2 and cleaner 3 and grind a closed loop comprising a system of grinding units, a reservoir pool 5 and a return pipe 23. Ground pulp through a thickener 6 is fed to a mixer-homogenizer 7, where it is evenly mixed with the heated economizer 21 and unit 22 cleaning with water. The pulp heated and brought to the working concentration in this way is fed to the homogenization tank 8, from where the pulp dispenser 9 is fed to the mixer 15. The perlite expanded in the device 10 through the precipitator, V. 1 1 1 is sent to the silo-storage 12, from where through the receiving bin 13 and the dispenser lA of expanded perlite, it is also fed to the mixer 15, where additives are also fed. In the mixer, the pulp of the fibrous component, expanded perlite and additives are mixed to a homogeneous state and the finished hydromass is fed to the receiving hopper of the unit 1b for feeding and shaping the hydromass, where a certain technological reserve is created.

In the supply and molding unit 1b, the hydromass is dehydrated and molded into the product. The water pressed in this way is supplied to the economizer 21 and the cleaning unit 22 by pipes 25 and 26, where it is heated by the exhaust gases of the heat treatment chamber 19. After that, the heated water is supplied back to the homogenizer-mixer 7 by the pipes 27 and 28. Thus, after the second cycle of the production line, the mass already preheated enters the heat treatment chamber 19, which significantly intensifies the drying process and saves energy and

water, with the same purpose, from the precipitating device 11 to the heat treatment chamber 19, the collector 29 is fed 1cc the flue gases of the intumescent device 10. The dried plates in the cutting unit are formatted and stacked, and if necessary, multilayered plates are obtained by gluing or stitching with a single layer - some.

The cuttings formed during the cutting are collected in the waste receptacle of the cutting unit 20 and conveyor 32 is fed to the homogenizer-mixer 7, where they dissolve and return to the production cycle.

If necessary, an appropriate amount of fresh water is fed to the system via economizer 21.

The proposed production line allows you to significantly reduce the cost and improve the quality of the products, increase productivity and use energy and material resources as efficiently and economically as possible. In addition, it is practically waste-free and ecologically clean, since after passing the flue gases through the entire cycle and leaving the wet-cleaning unit, the degree of purity reaches 99.9%:
