(54) TECHNOLOGICAL LINE FOR THE MANUFACTURE OF BUILDING HEAT-INSULATING PRODUCTS

one

The invention relates to the construction industry and is intended for the manufacture of building products with thermal insulation properties.

The known production line for the manufacture of building heat-insulating products, containing sequentially interconnected transporting devices and spacer preparation units arranged in a technological sequence with dispensers of reagents, a mixer, a droplet-forming mechanism of the granulator and a substance, a unit of forming articles with dispensers for the granules of a filler and a binder , a dispenser for dispensing the mass into the forms with a baffle, a chamber for heat treatment of products and a dismantling unit with packing goth O products 1.

A disadvantage of the known process line is its technological complexity and high energy costs.

The purpose of the invention is to simplify the process and reduce energy possibilities.

This goal is achieved by the fact that in the production line for the manufacture of building heat-insulating products containing sequentially interconnected transporting devices and spacer preparation units arranged in a technological sequence with dispensers of reagents, a mixer, a droplet-forming mechanism-granulator and a dryer, dispensers for granules of filler and binder, dispenser for dispensing mass in forms with a stirrer, product heat treatment chamber Alubki with packaging. Ready

10 products, a dryer unit for the preparation of aggregate granules is installed in front of the product molding unit, and the droplet-forming mechanism is made in the form of vibrofilters.

The drawing shows schematically a technological tini for the manufacture of building heat insulating products.

The technological line contains a unit for the preparation of a filler, which includes a container 1 with a dispenser 2 for liquid glass, dispensers 3 and 4 for the original components. Dispensers 2-4 are connected to mixer 5. At outlet of the mixer, an add-on device 6 is installed with a droplet-forming mechanism 7, made in the form of vibrofilters, placed above the fto top of f 8, which is filled with calcium chloride solution. Calcium chloride solution is obtained using a screw conveyor 9, crusher 10, hopper 11, metering device 12, reactor 13, metering device 14. Granulator 8 is connected to conveyor 16 located above hot air duct 17 by means of conveyor 15 18 is connected to the stirrer 19 of the molding unit of article 20, to which the binder dispenser 21 is also connected. The mixer 19 is connected to a hopper 21 connected to a hopper 23 located above the conveyor 24 carrying molds 25 for heat insulating products, passing inside the heat treatment chamber 26 and connected to the stacker of the products 27 of the stack in the form-removal and piling unit 28. A conveyor 29 and a form feeder consisting of two hydraulic cylinders 30 and 31 are provided for returning empty molds 25.

Technological line works as follows.

A granulate is produced in the filler preparation unit. For this purpose, liquid glass, borax, aluminum fluoride are supplied to the mixer 5 from dispensers 2, 3 and 4. In the mixer 5, the mixture is transferred through the dispenser 6 and the vibrofilter 7 is passed into the granulator 8, filled with chlor1250-300 solution

In this mode of heat treatment, the raw material mixture swells and hardens. The finished heat insulating products 27 by the stacker 26 are stacked. The forms used on conveyor 29 are not returned for the next cycle.

The use of this technological line for the manufacture of thermal insulation products reduces the duration of the technological process, which provides a significant reduction in the cost of thermal insulation products, reducing the specific energy consumption.

Claims (1)

Invention Formula Technological line for the manufacture of building insulation products, containing series-connected Calcium or magnesium calcium, which is prepared in a reactor 13 filled with water, is added by adding calcium chloride from bin 11 through dispenser 12. Calcium chloride pre-fed by conveyor 9 is ground in crusher 10. The level of calcium chloride solution in the granulator is maintained automatically. In granulator 8, a mesh conveyor 15 is mounted, moving the precipitated granules to the free end of the granulator. From the conveyor, the pellets are transferred to the conveyor 16 or to the dryer drum, where they are dried with heated air. The granulate obtained is poured into the metering hopper 18. From the metering hopper, the granules are fed into the mixer, where also the binder, which is the initial composition, flows from the mixer 5 through the metering unit 21. Everything is mixed for 10 minutes. Next, the mixture is loaded into the hopper 22. The withdrawn portion of the mixture is used to fill the forms 25 on the conveyor 24. The conveyor delivers the forms 25 with the mass laid in them to the heat chamber 26, which is a roller type tunnel kiln. The total residence time of the mold in the furnace is 3.5 hours. In the process of passing through the oven the mold filled with the mixture is subjected to heat treatment in the following mode 2.5 between each other with transporting devices and processing units located in the technological sequence; aggregates with reagent dispensers, a mixer, a droplet-forming mechanism-granulator and a dryer; a product forming unit with dispensers for aggregate granules and a binder; a mass dispenser for dispensing into forms with a mixer, a heat treatment chamber for products and a stripping unit with packaging of finished products, characterized in that, in order to simplify the process and reduce energy consumption, the dryer of the cooking unit The filler granules are installed in front of the product molding unit, and the drop-forming mechanism is made in the form of vibration filters.
