Description

The complex for the utilization of reinforced concrete sleepers in railway transport relates to the field of railway transport, namely, auxiliary devices related to the processing of used and slept reinforced concrete sleepers, and can be used in places of mass storage of used sleepers.

A stone crusher is known from the prior art, which allows crushing stone into fractions of various sizes and consisting of a crushing plant, a screen and a bunker located underneath. In this stone crusher, the stone is thrown into the throat of the crushing device, and then the crushed stone goes to the screen and is distributed among the bunkers (see SU 54075, published 01.01.1938). This stone crusher is accepted by the applicant as the closest analogue of the claimed technical solution.

The disadvantages of the stone crusher mentioned above are, first of all, the inability to process long products of stone, concrete, and even more so to utilize standard reinforced concrete sleepers having a length of 2700 mm, and steel wire 3 mm in diameter with a nominal number in the sleepers of 44 is used as reinforcement .

The present invention is aimed at increasing the reliability and ease of use of the complex due to the complete utilization of sleepers to obtain crushed stone and cleaned scrap of reinforcing steel, as well as to perform operations on a closed environmentally friendly cycle, characterized by low noise and dust, as well as the absence of harmful emissions into the atmosphere .

The specified technical result is achieved due to the fact that the recycling complex for reinforced concrete sleepers in railway transport contains a crushing plant, a screen and a hopper located under it, moreover, according to the invention, the crushing plant is made with receiving and output trays and installed at an angle of 50 ° to the horizontal plane on the support foundation farm, under the output chute of the crushing plant there is an unloading conveyor for transferring the crushed mass to the intermediate conveyor, at the end of the unloading An iron separator is provided for the conveyor, separating reinforcement and other metal objects from the crushed mass, and a lateral conveyor is located under the discharge end of the intermediate conveyor, through which the crushed mass is fed to a screen, where it is divided into three fractions and fed to a hopper made with three compartments, and under a dump conveyor is located in each compartment, and the complex contains a second crushing plant for crushed mass that has not passed through the screen sieves that roll under the influence of vibration of the screen into the receiving tray of the second crushing plant, then through the output tray of the second crushing plant enters the return conveyor and again through the side conveyor returns to the vibrating screen.

These features are significant and interconnected with the formation of a stable set of essential features sufficient to obtain the desired technical result.

The analysis of technical solutions showed that none of them contains both the entire set of essential features of the proposed complex for the utilization of reinforced concrete sleepers in railway transport, and distinctive features, which allows us to conclude that the proposed complex for the disposal of reinforced concrete sleepers in railway transport has “novelty” "And corresponds to the" inventive step ".

The essence of the invention is illustrated by drawings.

In Fig.1 shows a general recycling complex for reinforced concrete sleepers, in Fig.2 is a top view.

The recycling complex for reinforced concrete sleepers in the railway transport contains a manipulator (1), with which the sleepers are fed into the receiving tray (2) of the crushing plant. The crushing plant (4) is located at an angle of 50 ° to the horizontal plane at a height of two meters on a support and foundation farm specially designed and manufactured for this purpose (3). The crushing plant is made with receiving (2) and output (5) trays, and an unloading conveyor (7) is located under the latter for transferring the crushed mass to the intermediate conveyor (8). At the end of the unloading conveyor, an iron separator (6) is provided, which separates reinforcement and other metal objects from the crushed mass. A lateral conveyor (9) is located under the unloading end of the intermediate conveyor (8), through which the crushed mass enters the screen (10), where it is divided into three fractions: 0-5 mm, 5-20 mm, 20-40 mm and enters the hopper (11), made with three compartments, with a dump conveyor (12) located under each compartment. For fragmented masses larger than 40 mm, which did not pass through the screen, the complex contains a second crushing plant (13). This crushed mass (crushed stone) not screened in the screen rolls under the influence of screen vibration (10) into the receiving tray of the second crushing plant (13), and the output tray of the second crushing plant is located above the return conveyor (14). Thus, a closed loop sorting and crushing.

The complex utilization of concrete sleepers in the railway transport is as follows.

Reinforced concrete sleepers that were in use and have served their time are delivered by a loader or a platform to the area of operation of the manipulator (1). Using the manipulator (1), the sleepers are fed into the receiving tray (2) of the crushing plant, through which, under the action of gravity, they enter the crushing plant (4). In a crushing plant, crushing process (4) is performed, for example, by a jaw crusher. Under the influence of the complex movement of the corrugated plate in the crushing plant, the concrete mass of the sleepers in the rubble is destroyed and metal products (reinforcement) are separated from the concrete. The crushed mass (crushed stone) with the sizes of parts from 0 to 120 mm and separated by metal (reinforcement) with a length of 2700 mm is fed through the output tray (5) of the crushing plant to the discharge conveyor (7), which feeds the crushed mass (crushed stone) to the intermediate conveyor (8). At the end of the unloading conveyor, an iron separator (6) is installed, which separates the reinforcement and other metal objects from the crushed mass (crushed stone). The crushed mass (crushed stone), purified from metal objects (reinforcement), is fed to a vibrating screen (10) through a side conveyor (9), where it is divided into three fractions: 0-5 mm, 5-20 mm, 20-40 mm and enters the hopper ( 11), made with three compartments. A dump conveyor (12) is brought under each compartment. The crushed mass (crushed stone) larger than 40 mm, which did not pass through the screens of the screen (10), rolls as a result of screen vibration into the receiving tray of the second crushing plant. The mass (crushed stone) crushed in the second crushing plant (13) through the output chute of the second crushing plant (13) and the return conveyor (14) is re-sorted into this vibrating screen (10), where it is divided into three fractions and fed to the hopper (11) . This forms a closed cycle of sorting and crushing of the destroyed concrete mass of sleepers.

The main product of the processing of reinforced concrete sleepers is crushed stone. The crushed stone of three fractions obtained after separation in a vibrating screen complies with the state standards of the Russian Federation (GOST 8367-93), which allows its further use in road construction, as well as for the preparation of concrete mixtures for various purposes. Crushed stone with a fraction of 0-5 mm contains up to 20% unbound cement, which significantly increases the strength of concrete mixtures when using this crushed stone as a filler.

Sleepers are accepted for crushing without preliminary preparation, thus, this installation allows you to utilize the sleepers as a whole, without first dividing it into parts.

The use of the complex for the utilization of reinforced concrete sleepers in the railway transport will make it possible to recycle used and outdated reinforced concrete sleepers, which practically do not decompose under natural conditions.

The use of the complex for the utilization of reinforced concrete sleepers in railway transport will allow us to abandon the cost of allocating land for storing these sleepers, as well as return to the production and business cycle up to 90% of waste in the form of crushed stone, scrap, reinforcing steel and building materials obtained using products processing used sleepers.

In addition, the claimed recycling complex for reinforced concrete sleepers can be located in close proximity to settlements, because it is characterized by low noise and dust, as well as the absence of harmful emissions.

The present invention is industrially applicable and can be manufactured using conventional technologies and materials used in the art.
