Definitions
- the invention relates to the field of waste rubber products, in particular, worn-out tires.
- a known method of processing worn-out tires and rubber products (RF Patent JVTe 2211144, B 29 B 17/00, Bq> l. Ne 24,2003), in which the raw materials are heat treated in an extractor filled with oil products at a temperature of 260-290 C to full dissolving rubber. The process is carried out in a rotating perforated drum, the resulting rubber-bitumen composition is poured, the residues in the basket are washed, crushed and soot is removed, while vacuum distillation of the liquid oil and the rubber decomposition product is carried out.
- the disadvantage of this method is the need for preliminary operations of fragmentation and heating of tires, the complexity of the equipment and the cyclical process, as a result of which the method does not provide high performance.
- the closest in technical essence is the method of processing rubber-containing wastes selected as a prototype (RF Patent JVfe 2057012, B 29 B 17/00, BEOL. Nf.9, 1996), which includes thermal decomposition of waste at a temperature of 250-280 C in a medium of boiling hydrocarbons with the formation of a gas-vapor mixture and a suspension of degraded rubber in them, their separation, while the raw material is preliminarily and sequentially processed by the condensation product of the gas-vapor mixture and a suspension of degraded rubber to achieve a swelling of 5-60%.
- this method does not allow to utilize whole tires, the technological process requires stopping, therefore it also does not provide high performance.
- a device for implementing a method for processing worn tires and rubber products (RF Patent N ° 221 1144, 29 B 17/00, Bull. N224,2003), containing an extractor in the form of a cylindrical body, having a lock loading device in the upper part, input fittings - withdrawal of reagents, a device for loading raw materials and a device for vaporizing a gasoline extractant, while inside the extractor there is a rail for introducing a perforated drum and a drum rotation unit, in addition, the device is equipped with unloading and handling systems metal cord boots, a press for separating residues, a sink, a kiln, and a press for briquettes.
- the disadvantage of this device is the complexity of the design, the technological need to stop the processing process and, as a result, insufficiently high productivity.
- the closest in technical essence is the selected device for the disposal of waste rubber products, mainly used car tires (RF Patent ⁇ 2223172, ⁇ 29 ⁇ 17/00, Bull. JNfo4,2004), containing an extractor in the form of a cylindrical body with nozzles for input liquid source and output of finished products, a means of loading waste and unloading residues and a heater for liquid oil products in the form of a tubular heat exchanger located in the middle section of the extractor, divided by about the height of the partitions into three sections.
- an extractor in the form of a cylindrical body with nozzles for input liquid source and output of finished products, a means of loading waste and unloading residues and a heater for liquid oil products in the form of a tubular heat exchanger located in the middle section of the extractor, divided by about the height of the partitions into three sections.
- the disadvantage of this device is the inability to process a large amount of rubber raw materials due to the cyclical nature of the processing process and, therefore, low productivity.
- the basis of the invention is the task of improving the method of processing worn-out automobile tires, in which the process is achieved by continuous heat treatment of raw materials in the melt of products and / or oil products to the degree of plastic deformation of the rubber and directing the swollen tires into a separator for separation into rubber-containing mass and metal cord residues and, as a result, the productivity of the processing method is increased.
- the problem is solved in that in a method for processing worn automobile tires, including heat treatment of tires to achieve swelling, according to the invention, heat treatment is carried out in the melt of products and / or oil refinery waste, tires swollen and softened to the degree of plastic deformation of the rubber are sent to a separator, where they are divided into a rubber-containing mass and metal cord residues, and the obtained separation products are sent for further processing.
- the use of a new technological operation in the processing method the mechanical separation of softened rubber and steel metal cord — creates the prerequisites for the formation of a high-performance technology for large-scale production of used tires for recycling.
- Comparative analysis with the prototype shows that the method differs in that heat treatment can only be carried out until the tires swell and soften, and not until they are completely dissolved.
- As liquid products, products and / or refinery waste can be used.
- the movement of swollen tires in the separator, their separation into a rubber-containing mass and metal cord residues and continuous unloading of separation products make it possible to carry out constant reloading of raw materials.
- the method does not require preliminary fragmentation of the tires.
- the basis of the invention is the task of improving the device for processing worn-out car tires, in which, by installing an inclined feeder at the bottom of the casing, which moves the swollen tires into a separator in the form of a screw press, which separates the tires into a rubber-containing mass and metal cord residues, the processing process is continuous and as a result, the productivity of the processing method is increased.
- the means for loading waste is made in the form of a gateway, at the bottom of the casing there is an inclined feeder for moving swollen tires, above the receiving head of which on the upper part of the casing there is fixed a flow restrictor of tires made in the form of grates, They are arranged in the direction of flow movement, and under the discharge head of the feeder there is a separator receiving device, which is made in the form of an inclined screw press, the outlet opening of which serves to unload the metal cord residues and is located above the melt level behind the housing wall, while the screw and the external press casing have a conical shape, and the press casing in the area located inside the housing is perforated to release the rubber mass.
- Comparative analysis with the prototype shows that the proposed device is equipped with an inclined feeder for moving swollen tires to separate them into a rubber-containing mass and metal cord residues using a screw press. To limit the flow of tires entering the feeder, the device is equipped with inclined grates.
- the present invention allows to obtain a technical result, which consists in increasing the productivity of processing worn automobile tires.
- the device comprises a housing 1 with channels for inputting the initial liquid raw material 2 and outputting the rubber-containing composition 3, a gateway for loading waste 4, a heater for liquid products 5, an inclined feeder 6, above the receiving head 7 of which on the upper part of the housing 1 are mounted inclined grates 8, under the unloading head 9 of the feeder 6 there is a receiving device 10 of the screw press 11, which consists of a screw 12 and an outer casing 13.
- the outlet of the press 14 serves to exit the remains of steel cord.
- a device for implementing the method works as follows.
- the housing 1 is filled to 2/3 of the height with oil products and / or waste products, they are heated to a temperature of 250 ° C using a liquid product heater 5.
- a waste loading gateway 4 load a batch of tires (the fill factor of the volume of the receiving part of the casing is 0.4). Tires are heat treated for 3.5-4.5 hours, during which time the rubber component of the tires reaches the degree of plastic deformation, the tires soften, swell and lower to the bottom of the housing 1, fall on the inclined feeder 6, which moves them to the receiving device 10 of the screw press 11.
- this method allows for continuous processing of worn automobile tires. For example, for a case with a receiving volume of 100 cubic meters, the daily output will be 240 tons of processed raw materials.
- the resulting rubber-containing mass can then be used as a constituent component for the production of road or building bitumen, and subjected to pyrolysis or thermolysis for the production of synthetic gas, motor fuels, carbon black and other chemical products.
- the remains of the metal cord are secondary raw materials for the metallurgical industry.
