Description

The utility model relates primarily to equipment for the processing of rubber products, for example worn and defective tires, and can also be used for the production of floor coverings by hot pressing, free cold laying and spraying.

A well-known factory for the disposal of automobile tires, containing vehicles, a workshop for delivery and storage, a workshop for sorting and preparation, a workshop for destruction and destruction, a workshop for packaging and shipping, a workshop for producing liquefied gases, a workshop for cooling automobile tires and a vehicle for delivering liquefied gases from a workshop for producing liquefied gases in the workshop for cooling automobile tires, while the destruction and destruction workshop is equipped with impact destructive means in the form of hammers and mills (see RF patent No. 2026183, IPC ВВВ 17/00, 1995).

A disadvantage of the known plant is the increased complexity and cost due to the use of liquefied gases, as well as the need to strengthen security measures.

As the closest analogue, a used tire recycling line is used, comprising a machine for separating the metal part of the bead ring connected by transport devices, a machine for radially cutting tires, a machine for grinding tires, a machine for producing large rubber crumbs, a machine for producing fine crumbs, the output of which is installed means for separating crumbs by size, magnetic separator, installations for separating textile cord (see RF patent No. 2172243, IPC V29B 17/00, 2000)

The main disadvantage of this technical solution is the insufficient degree of purification of rubber crumb from textile cord, the limited scope and the impossibility of recycling worn tires.

The task to which the proposed technical solution is directed is to develop a processing complex for all types of tires, including tires with a mixed cord type (rubber, metal, textile), which is highly reliable and provides the possibility of complete disposal of tires to produce high-quality commercial products.

The technical result that is achieved when solving the problem is expressed in improving the level of cleaning from metal and textile inclusions, as well as in improving the environmental friendliness of the process.

The problem is solved in that a machine for removing the bead wire is used as a machine for separating the metal part of the bead ring, scissors are used as a machine for radially cutting tires, a complex of sequentially installed crushers and crushing rollers is used as a tire grinding machine, as a granulator used to grind pieces of tires to a particle size of less than 10 mm was used as a machine for producing large rubber crumbs; fine rubber crumbs used in parallel mounted knife granulators, made with the possibility of grinding large rubber crumbs to a particle size of less than 4 mm, as a unit for separating textile cord used parallel installed textile separators.

At the outlet of the granulator there is a device for simultaneous separation of crumbs by size and separation of metal cord, which is used as a magnetic picker, including a vibrating table with a magnetic separator, and also after parallel knife granulators, a device for separating crumbs by size is used, which is used as a vibration table made with the possibility of separating the grinding products into a fraction of a particle size greater than 1.5 mm and a fraction of a particle size of less than 1.5 mm, transported by separate ortnymi lines, each of which has a separate textile separator.

Also, vibrating screens are installed above the storage bins of the automatic packers to separate the finely divided crumbs into fractions.

The inventive utility model is illustrated in the drawing, which shows the tire recycling line.

The drawing shows a machine for separating the metal part of the side ring 1, a machine for radially cutting tires 2, conveyors in the form of conveyor belts 3, a machine for grinding tires in the form of a complex of sequentially installed crushers 4 and crushing rollers 5, a machine for producing large rubber crumbs 6 , a device for the simultaneous separation of crumbs by size and separation of the metal cord 7, screw conveyors 8, machines for producing fine rubber crumbs 9, pneumatic transport 10, the device for separating crumbs and by size 11, magnetic separator 12, vertical screws 13, plants for aerodynamic separation of textile cord 14 and 15, screw feeders 16, vibrating screens 17 and machines for automatically filling bags 18 and 19. The tire processing line operates as follows. The sorted tires to be processed by the conveyor are fed into the machine to isolate the metal part of the bead ring 1 of a known design, which draws a wire ring, then tires larger than 750 × 140 mm are cut into parts by a radial tire cutting machine 2.

Next, small tires and pieces of large tires by conveyor 3 are fed into the crusher 4, which consists of a crushing chamber and a return sifter. The sifter is made in the form of a rotating drum with 40 × 40 mm holes with a crushing chamber installed inside, in which two counter-rotating shafts with 40 mm wide blade knives are installed. The tire is captured by knives and torn into pieces, with pieces larger than 40 × 40 mm being thrown by the screener back into the crushing chamber, and smaller pieces by conveyor 3 are fed to crushing rollers 5.

Crushing rollers are structurally two drums, the gap between which is adjustable from 10 to 1 mm and which rotate towards each other at different speeds. Moreover, one drum has a smooth surface, and the other is made with cutting.

The resulting mixture of pieces of rubber, wire and textile using the conveyor 3 gets into the machine to obtain large rubber crumbs 6, where it is fed by a metering screw from a loading funnel into the crushing zone. The crushing zone consists of a shaft of a special shape and a sleeve, the inner part of the sleeve and the end of the shaft having the shape of a cone with a thread in the form of longitudinal grooves on the surface. The mixture is captured by the screw of the working shaft and pushed into the annular gap between the sleeve and the cone of the working shaft, while the width of the gap can reach 3 mm At this stage, the rubber fragments are crushed to a size of less than 10 mm, the textile and metal are separated.

Then the mixture is fed by the conveyor 3 to the vibrating table of the device for simultaneous separation of crumbs by size and separation of the metal cord 7, where under the action of vibration it is evenly distributed and slowly moves to the discharge funnel. Moreover, a magnetic separator is installed above the vibrating table, under the influence of which the wire is attracted to the tape and carried away into the storage tank.

The exposure time of the magnetic field is about 2-3 seconds, at this stage more than 95% of metal inclusions are separated.

Next, a mixture of rubber granules and textile cord falls on two parallel screw conveyors 8 and is fed into machines for producing fine rubber crumbs 9, consisting of a housing with fixed knives, a shaft with movable knives and a mesh with 4 mm holes. When the shaft rotates, the particles of raw materials are cut with knives, as a result, the remains of the metal and textile cord are finally released.

The mixture is supplied by pneumatic transport 10 to a crumb separation device 11, which is an inclined rectangular structure with a bottom of a solid sheet and a sieve with holes of 5 mm installed parallel to the bottom. Under the influence of reciprocating movements and tilting, the mixture slowly moves to the discharge funnels.

Then, conveyor 3 rubber granules and small textile fibers are fed to a magnetic separator 12, which selects the remnants of the fine wire released during grinding in machines to produce fine rubber crumbs 9.

After the vibrating table 11, the mixture is divided into two transport lines, depending on the diameter of the mesh openings: crumbs with a particle size of 1.5-3 mm and a particle size of less than 1.5 mm.

Further, along the vertical screws 13, the mixtures enter the units for separating textile cord 14 and 15, consisting of a housing and a vertical shaft with blades installed inside, and the separators 14 and 15 are configured for different strengths of the internal air flow in accordance with the quality, composition and fraction of the mixture on the entrance. The lower part of the body is made in the form of a cone with a funnel in the lower part. A smaller cone is mounted inside this cone with a nozzle in the lower part exiting the cone at an angle through the wall of the outer cone. At this stage, the final cleaning of the fabric from the textile cord takes place.

The cleaned crumb by screw feeders 16 rises to vibrating screens 17, where it is divided into fractions, and then collected in the storage hopper of automatic packers 18 and 19, designed to automatically fill the bag to a predetermined weight.

The filled bag is conveyed to the packaging device where it is sewn up.
