Description

The invention relates to the field of construction, in particular to the utilization of used roofing, the processing components of which can be used in the repair and construction works on the roofs, as well as in road repairs and the release of new bituminous materials.

There is a method of processing bitumen roll materials, in which the latter are loaded into a container and kept in the presence of hot bitumen until the coating mass is separated from the base [1].

The basis of the rolled bitumen material in the implementation of this method is burned using heat to preheat the bitumen tank.

The disadvantage of this method is that it allows you to select and use only the bitumen component of the rolled materials due to the loss of the burned base.

There is a method of extracting bitumen from roofing materials, in which the roofing materials are crushed, placed in a tank with heated bitumen-dissolving substance, produce bitumen and remove insoluble solid fractions [2].

This method is carried out with the use of various bitumen solvents, which makes it harmful to health and maintenance personnel. In addition, it is quite energy-intensive, which increases the cost of final products of processing.

Known installation for grinding, comprising a housing in which a grinding chamber is installed, made with holes, a rotor shaft with grinding elements [3].

The method of processing carried out on this installation involves pre-cutting the ruberoid carpet into pieces, crushing the pieces with simultaneous separation of bitumen in the form of chips, and separation of bitumen and base.

This method is carried out only at ambient temperatures not higher than 10 ° C, at which the bitumen remains solid and retains its brittle properties.

At temperatures above 10 ° C, the bitumen softens, which sticks to the inner surfaces of the grinding chamber, as a result of which the installation becomes impossible.

A feature of roofing works is the fact that they can be carried out in the presence of positive temperatures.

As a result, waste of bitumen materials in the form of old roof coatings appear in large quantities in the warm season, so it is subjected to cooling during this period.

The cooling process is long, energy intensive and inefficient.

The need for cooling the material increases the cost of the final product. In addition, the operation of the installation is accompanied by dust formation, which adversely affects the health of the staff.

A complex for processing bituminous roofing materials is known, which contains a machine for cutting old roofing material into pieces, a shredder, a conveyor for feeding ruberoid pieces to a shredder, a means of eliminating sticking of bitumen on the working elements of a shredder, an installation for sorting crushed material with a multifaceted rotating drum and outer perforated walls on it, tubular casing for connecting the chambers of the shredder and drum, installation of collecting dusty bitumen with air deflectors and the device Displayed outwardly purified air, the air pipe for connecting the cameras and setting sorting installation collecting pulverized bitumen, bituminous drives powder pulverized and crushed asphalt bitumizirovannogo paperboard, as well as bituminous powder melting installation and pulverized bitumen [4].

However, there are certain disadvantages.

The disadvantages of this complex include the following.

First, the working shaft of the chopper is made elongated, which, on the one hand, complicates the design and increases the metal intensity, and on the other hand, predetermines the execution of the connecting tubular casing curved, resulting in accumulation of crushed material in bends, increasing resistance, difficulty in throughput the ability and frequent downtime due to the elimination of these savings, which reduces the performance and efficiency of the complex, and also significantly worsens the conditions of service.

Secondly, the external perforated walls of a multi-faceted drum of the sorting plant are made of metal mesh with holes to create and feed only a large fraction of the bituminous powder into the accumulator, and there is no possibility of obtaining the fine fraction of this powder in production, which reduces the functional and technological capabilities of the complex, as well as

- 1 012322 limits its scope.

Thirdly, the side perforated walls of a multifaceted rotating drum, made of metal mesh, which is not strong enough and durable, therefore, often fail, which negatively affects the efficiency of the complex.

Fourthly, the installation of sorting and the installation of collecting dusty bitumen are located separately in individual chambers, which significantly increases the overall dimensions of the complex, its metal content and the production areas it occupies.

Fifth, there is no equipment in the complex for preparing a wide range of new diverse bitumen-containing materials from the obtained components of recycled old roofing ruberoid coatings, which significantly reduces the functional and technological capabilities of the complex and limits its scope.

Sixthly, there are no means of forming the necessary portions of bitumen powder and pulverized bitumen to install their melting, as well as bitumenized cardboard for specific equipment, which slows down the production process and significantly reduces the efficiency of the complex.

The proposed complex for the processing of bituminous roofing materials works as follows.

The layers of the old ruberoid roofing are subjected to cutting on the wall 1 into pieces.

The conveyor 3 cut pieces served on the chopper 2, on which they are mechanically broken and crushed.

At the same time, the tool 4 provides the exception sticking of bitumen on the working elements of the grinder.

When grinding the pieces, the coating mass of bitumen separates from the cardboard base and bitumen turns into fine-grained material - bitumen powder, and the cardboard base breaks into small pieces.

Next, the crushed material passes through the calibration grid 55 under its own weight and due to the air flow generated in the grinder, flows directly freely through the cavity of the tubular casing 8, and then inside the rotating drum 6.

Since the protective box 25 of the kinematic connection 24 is made trapezoidal in cross section, the non-working section 56 of the ground material intake zone is minimized and it does not linger along the inclined side walls and moves downwards, which contributes to the overall performance of the complex.

Since the tubular casing 8 is positioned vertically and is made without bends, conditions are created for significantly reducing the accumulation of crushed material on its walls, reducing resistance and increasing throughput, which also contributes to improving the efficiency of the complex.

In the rotating drum 6, powdered bitumen is poured out through the holes 29 in the outer walls 7 and enters the drive 13, and the shredded cardboard is separated and fed to the drive 15.

Dusty bitumen enters with the air flow from the section of the chamber 27, where the sorting installation 5 is located, through the air duct (window) 12 on the vertical dividing wall 28 into the section where the installation 9 of collecting the dusty bitumen is located.

The air flow in the section with the installation 9 on its way meets with the air deflectors 10, as a result of which the dusty bitumen separates from it and enters the accumulator 14, and the air flow is finally cleaned on the device 11 and goes outside, observing the requirements of non-pollution of the environment.

Subsequently, as the accumulators 13, 14, 15 are filled with the corresponding components of completely recycled old roofing material of roofing, the necessary portions are formed from them using individual dispensers and delivered to the container for delivery and direct use in certain installations for preparing specific bitumen-containing materials or for delivery to the warehouse and their subsequent use in prepared form.

For example, the dispenser 33 forms the necessary portion of the fraction of bitumen powder collected in the accumulator 13 and serves it in a container (not shown) for delivery to the object to perform the lower layer before each application of the asphalt-concrete mixture during paving, the dispenser 34 forms the necessary portion of this fraction and serves in a container for delivery to the installation 17 of mixing and preparation of a cold primer, the dispenser 35 forms the necessary portion of the same fraction and serves it in a container for delivery to the installation of the preparation of a hot primer and dispenser 36 form the necessary portion also of this fraction and serves in a container for delivery to the melting unit 16.

If a coarse fraction of bitumen powder is required for production, then when the complex on the multi-faceted drum 6 of the sorting unit 5 is completely stopped, after unscrewing convenient servicing nuts 31 on them, the outer perforated walls 7 previously used are quickly removed and a new one is installed in their place a set of similar walls, but with holes 29 for the formation of the necessary large fractions of bituminous powder.

With sufficient filling of the accumulator 13 with a large fraction of bitumen powder with a dispenser 37, a necessary portion is formed from it and supplied to the container for delivery to the installation 19 of the VIR-formation mixture preparation.

When the accumulator 14 is sufficiently filled with dusty bitumen, the dispenser 38 forms the necessary portion of it and serves it in a container for delivery to the melting unit 16.

After the unit is loaded with 16, the necessary portions of the dusty bitumen and the fine fraction of the bitumen powder carry out their melting.

When the accumulator 15 is sufficiently filled with shredded bituminized cardboard, the dispenser 39 forms the necessary portion of it and serves it in a container for delivery to the VIR-mixture preparation mixture 19 and the dispenser 40 also forms the necessary portion from it and serves it in the container for delivery to the pressing unit 20.

After loading the installation 20 of the required portion of crushed bituminous cardboard, it is compressed and granulated.

After loading the installation 17 the required portion of the fine fraction of bituminous powder, dosato

- 6 012322 rum 41 form the necessary portion of the solvent and serve in a container for delivery inside this installation, after which they carry out the mixing and preparation of a cold primer.

After completion of the preparation of the cold primer on the installation 17, the dispenser 42 forms the necessary portion of it and serves it in a container for delivery to the objects of waterproofing the building structures, as well as the foundations of the roofing and road surfaces.

After loading the unit 18 with the necessary portion of the fine fraction of bituminous powder, the dispenser 43 forms the necessary portion of the plasticizer additive and serves it in a container for delivery to the inside of this unit, after which the preparation of a hot primer is carried out.

After the preparation of the hot primer at the installation 18 by the dispenser 45, the required portion is formed from it and delivered to the container for delivery to the waterproofing facilities of the building structures, as well as the roofing and pavement bases, and the dispenser 44 forms the necessary portion of the bituminous sediment and is fed to the container for delivery on installation 19 of the preparation of a mixture of VIR-layer.

At the end of melting at the installation 16, the dispenser 46 forms the necessary portion of the finished secondary bitumen and serves the container for delivery to the plant 21 for the manufacture of roofing materials, and the dispenser 47 forms the necessary portion of the bitumen-mineral sediment formed and serves it in the container for delivery to the mixture preparation station 19 VIR reservoir.

After the installation is filled with 19 necessary portions of a large fraction of bituminous powder, crushed bituminous cardboard, and bitumen-mineral sediments, a mixture of the VIR-layer is prepared.

From the prepared mixture of the VIR-layer, the dispenser 48 forms the necessary portion and serves it to the container for delivery directly to the object to perform the lower waterproofing layer of roofing coatings.

After pressing on the installation of 20 crushed bituminous cardboard with a dispenser 49, the required portion of the obtained granules is formed and delivered to the container for delivery to the manufacturing facility of hot asphalt concrete mix and used as a necessary component.

Upon receipt at the installation 21 of the necessary portions of secondary bitumen, dispensers 50, 51, 52, 53 form the necessary portions of fiberglass (fiberglass), polyethylene film, waste engine oil, floury filling material, and serve on the corresponding actuators of this installation.

The resulting roll roofing material is packaged in a special device 54 with the possibility of delivering it to a storage warehouse or an object for carrying out a soft roof from it.

The proposed use of packaging for all portions packaged components obtained from completely recycled old ruberoid coatings, if necessary, also allows them to be stored in the warehouse with subsequent use without preparation at the appropriate facilities for preparing a wide range of different bitumen-containing materials.
