The invention relates to the manufacture of building products from bulk materials and polymer waste and can be used for tile, roofing materials, chemical resistant floorings, tiles and other construction materials.

Currently manufactured polymer-containing plates or panels for various purposes widely used method for the production of construction products, in which the system is used for the manufacture of construction products from bulk materials and polymer waste. The system includes devices crushing polymeric materials with heater sand, interconnected production lines, as well as the mold is finished articles from the conveyor line feed products (RU # 94008420, SW 26/00, publ. 10.11.1995).

To implement this method is used for the production of roofing and construction material containing device fragmentation of polymer waste and heat of the sand, the inputs of which are connected respectively with the supply line of polymer waste and sand, and the output from the mixer sand and polymer waste, mold finished products, connected to the output supply line products, further provided with a hydraulic pressure, an input connected to the output of the mixer, and the output is connected to I the house of the mold finished products, temperature sensors sand and a mixture of sand and polymer waste, United electric lines of communication with the inputs of the computing device, the outputs of which are connected by communication lines with electrical control devices mounted respectively on the mold of the finished products, the heating device of sand, device fragmentation of polymeric wastes, sand mixer and polymeric wastes, hydraulic press (RU # 2185959, WV 15/00, WV 3/00, SW 26/00, publ. 27.07.2002,).

From the same source of known composition for the manufacture of products from bulk materials and polymeric wastes containing polymer waste and sand.

This decision was made as a prototype for the specified object.

The disadvantage of this solution lies in increased energy consumption and higher temperature of the feedstock. Thus, according to this solution assumes that the sand in the bunker storage, comes to the post of heating and heating to a temperature at which melting occurs polymer-containing components in the feedstock coming from another hopper. Thus, in the common mixing chamber preheated sand and level polymer-containing component must mix, sand should give the same proportion of their heat from this component to the and melted to education (when mixing) polymer-containing mixture with sand as a filler. In the mixing chamber additionally produce heating of the mixture to the melting process polymer-containing components was guaranteed. In this line, the heating of the sand is of a gratuitous nature, as there is a high consumption of electricity, and when reaching the set temperature of the sand latter moves into the mixing chamber, but the sand as quartz material is that it very quickly gives off heat to the environment. If you consider this feature. The path of the sand from the camera to its heating up of the mixing chamber should be minimal or absent, but this is almost impossible as the working conditions of components and assemblies related to the heating of the stove and mixed, different, have the features inherent in each process and may not be in close proximity to each other. Thus, the heated sand after transportation into the chamber offset from a polymer-containing component with much fallen by the temperature at which the polymer is heated, but not melted. Supply additional heat to the mixing chamber also requires a large power consumption and, in fact, this new warm-up is necessary to polymer-containing component is melted, which is possible only when the sand and this component of the overall temperature - temperature p is Alenia polymer. If we consider that all raw materials, including sand, are preliminary crushing and mixing, which is done in the shop, all the raw material acquires as a result, the temperature of the environment of the plant or close to it, and it can be assumed that this temperature is not negative. In this regard, dual heating does not give the efficiency and power consumption, which affects the value of the finished product.

The present invention is directed to the achievement of the technical result consists in increasing the manufacturability, the simplification and efficiency of the line to use in the different nature of the origin of the filler.

This technical result is achieved by the fact that in line for the production of roofing and construction material containing cumulative bins for the source of crushed raw materials consisting of polymer waste and filler received in the specified proportions by conveyor to the mixing apparatus, of which the stirred mixture on the conveyor enters the device heating the mixture to obtain a molten polymer-containing mass is moved to the pressing device for molding into sheet form of the finished product, each hopper is made with dispenser, made with the issuance of the weight portion of the feedstock on the left for all the storage bins with the mixing chamber, made in the form of a rotating drum with ribs on the inner surface of the wall, and the blades on an axis and having a window issue stirred mixture on the conveyor movement stirred the mixture in the device heating the mixture to obtain a viscous molten polymer-containing mass on the conveyor guided on rollers for forming into sheet form cloth fed by belt conveyor to the device pressing for molding into sheet form of the finished product and styling it to the post receiving the finished product, however. device heating of the mixture is an extruder having a tubular body within which is placed a shaft with a spiral-like vanes to move during the rotation of the mixture, and the pipe in the circumferential direction is set electric heating walls for heating the mixture to the state of the viscous molten polymer-containing mass at the outlet of the housing.

These characteristics are essential and interrelated with the formation of a stable set of essential features, sufficient to obtain the desired technical result.

The present invention is illustrated with a specific example of implementation, which, however, is not only possible, but clearly demonstrates the possibility of achieving the desired technical result

Figure 1 presents the scheme of the line for the production of roofing and building material.

According to the present invention considers the line for the production of roofing and construction material used for the manufacture of products made from any on the nature of the filler and the polymer-containing waste. As the polymer-containing waste is used agglomerate (secondary agglomerated film of high pressure all brands) and agglomerated stretch film, and as a filler - river sand, rice hulls, glass wool, wood chips, crumb rubber (waste tires), recycled fraction of plastic PET bottles.

Line for production of roofing and building material (1) contains the cumulative bins for the source of crushed raw materials (comes in ready fractured or incoming raw material is crushed in a separate crushers), consisting of polymer waste and filler. The line includes three main hopper 1 (tank) for different types of the main components of the feedstock and four auxiliary hopper 2 (reservoir) under dyes and additives. The specified number of bins (reservoirs) is conditional, as determined by the number of mixture components. Each hopper at the outlet of the raw material is set to the ATOR 3, which can be installed in portions of the dose in the bin of raw materials on the scales before the formation of the weight portion, corresponding to a given composition of the mixture. Verified by weight component of the feedstock from each tank separately supplied to the common chamber 4, where filled with the raw material comes in the specified proportions in the receiving part of the chamber apparatus 5 for mixing of all components. Thus, each hopper having a spout, made with the issuance of the weight portion of the feedstock in common to all the storage bins chamber and thence into the mixing apparatus. An apparatus for mixing of raw materials is a round tank (rotating from the drive drum) in the form of an oval in longitudinal section, is attached to the axis, inside on the inner surface of the fixed wall ribs, and on the axis of the blade. On the one end side opening for loading components on the other end side of the cylinder in the form of a cone for discharging the mixture (box of issue stirred mixture). In the mixing apparatus, having in the cavity of the drum edges and blades, mixing the components to obtain gomogenizirovannogo mixture with additional crushing of the components of the mixture due to the contact of collisions and friction and alignment of the temperature regime, which is determined by the initial temperature is mi raw components and leveled due to heat transfer from the warm components to the cooler.

After mixing, the mixture having a certain temperature, through the window issue stirred mixture fed to the conveyor 6 move stirred mixture of (conveyor belt or screw type, or any known, providing the movement of the bulk material, is powered by electric motor through reducer) in the accumulator tank 7 mixed components in the form of a container of rectangular shape with a belt pusher raw materials, where multimodal components dosed go (poured) into the device 8 heating the mixture used to produce polymer-containing viscous mass output by melting (slight melting of the polymeric components and encapsulating filler (simultaneous dissolution of the dyes and the interaction of additives with the weight of the polymer). Device heating of the mixture is an extruder having a tubular body within which is placed a shaft with a spiral-like vanes to move during the rotation of the mixture, and the pipe in the circumferential direction is set electric heating tena 9 for heating the mixture to the state of the viscous molten polymer-containing mass at the exit from the body of the forming head of the body). In more detail the design of such an extruder is described in the article "Extrusion", has been posted on the website "Plast Expert" company "G the PAP Polyplastic in Internet in online access at: http://www.e-plastic.ru/main/articles/r5, found 12.05.2011, the Execution of the extruder with externally located on the pipe along its length by tena provides a gradual heating of the mixture and gradually bringing the temperature of the mixture to the melting temperature (slight melting of the polymeric components.

The special feature of this line is that the direct cost of electricity for the preparation of polymer-containing viscous masses occur in the extruder where the temperature is maintained along the length of the shaft with blades in accordance with this regime, in which the output of the mass acquires a given consistency and it shows in the condition of the masses. The regulation of the heating temperature on the walls along the length of the extruder can be operated manually, but can be automated. Other costs of electric power supplied to the drive roller conveyors, machine mixing and other units of the line remain in accordance with the required load on the motor and gearbox in accordance with the modes of their operation.

Coming out of the outlet window (forming the head) viscous polymer-containing mass falls onto the conveyor 10 tape or oval (with powered by electric motor through reducer) and moves on rollers 11, where forming the mass in sheet form cloth 12. Used rubber rollers (6 ø the criminal code). Webs of rolled mass on the conveyor 13 (tape or salasaga type) move to the device 14 pressing for molding into sheet form of the finished product 15. The pressing device is made in the form, for example, a hydraulic press with a press-forms 16, the finished product 15 is cut to a predetermined shape on the perimeter in order to remove overlaps and compliance dimensions.

After pressing, the finished product in sheet form paver 17 of the finished product is placed in the stack and moves along the roller conveyor 18 for the post of reception of finished goods and rejection. Suitable products are stacked in piles on 19 pallets and discarded products 20 are deposited and sent to the crushing device 21 (the crusher) and processed in a crushing apparatus in the crumb, which is sent (by any known means of transporting crushed mass in the hopper 1 for polymer waste for reuse in the manufacturing process of construction and finishing plates.

The production is periodically continuous in nature and depends on the receipt of raw materials. Components come in scales, with weights in proportion poured into the mixing chamber of the raw materials, after mixing the mixture through the belt conveyor is injected into the extruder. In the extruder at a given temperature, providing the melting is of alimera, the mixture is pushed through the screw shaft, when it is melted and mixed into a homogeneous colored, viscous mass. The mass of the belt conveyor is fed to rollers, where once again stirred and rolled into the canvas, then cut a piece of 2 meters per pallet. The pallet on the roller carrier delivers the cloth in the mold. Mold under pressure within 30-50 seconds forms the shape of a sheet, then the sheet emerges from the press and trimmed the edge, the plunger pushes on the stacker where the accumulated stack of 150-200 sheets, wrapped with a ribbon and rollers is sent to the pallet.

Defective sheets are processed at the mill by grinding the pieces in size 3-6 see Further pulverized material is fed into the extruder, passing the scales and the mixing chamber.

The present invention is industrially applicable, tested and can produce cost-effective construction of lamina or products that have a high economic efficiency and practicality in a number of areas. For example, this line was mastered the production of roofing sheet. To produce one sheet or sheets for finishing five millimeter thickness and the size of two meters long and one meter in width, you must:
