Description

Technical Field

[0001] This invention relates to a coal and coke mixed storage and transportation system with a single row of multiple silos, belonging to the field of storage technology. Background Technology

[0002] In recent years, with increasingly stringent environmental protection requirements, open-air stockpiles have been increasingly replaced by silos. Silos offer various discharge methods. For belt conveyors, the cost of turning corners is significantly higher than that of a straight conveyor belt. Therefore, silos must be arranged in rows, with each row using an independent belt, to achieve optimal cost. However, in practice, it's difficult to ensure that a single material can be stored completely within a row of silos. To save storage space, storing two different materials in a single row of silos is a very common practice.

[0003] In existing technology, the silos are arranged in a straight line, and their top feeding end generally uses a single belt conveyor. Material is loaded by mobile unloading cars, plow unloaders, or placing cars. The material discharged from the bottom of the silo is generally discharged through discs and then flows into the discharge belt below, which transports it out of the silo.

[0004] At the top of the silo, multiple types of materials are fed through the same conveyor belt, posing a risk of material mixing within the same silo. At the bottom of the silo, multiple types of materials are discharged through the same conveyor belt, which also poses a risk of material mixing between different types, potentially leading to production accidents.

[0005] Furthermore, the silo only has one feeding and one discharging path at both the top and bottom, making it impossible to implement backup processes or simultaneously feed and discharge different types of materials. Any malfunction would severely impact the normal storage and transportation of materials, jeopardizing the stable operation of large-scale production. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the shortcomings of the above-mentioned technologies and provide a mixed storage and transportation system that can avoid the risk of mixing materials and can realize the simultaneous feeding or discharging of different types of materials.

[0007] To solve the above-mentioned technical problems, the technical solution proposed by this invention is: a single-row multi-silo coal and coke mixed loading and transportation system, comprising: N silos arranged in a straight line, a loading mechanism located above the silos, and a discharging mechanism located below the silos; starting from the first silo at one end, up to the nth silo, it is used for loading either coal or coke, and the remaining silos are used for loading either coke or coal, where n≤N; the loading mechanism includes a coal loading belt and a coke loading belt; the coal loading belt and the coke loading belt extend along the arrangement direction of the silos and are parallel to each other; the coal loading belt... The material on the conveyor belt and coke conveyor belt can be loaded into any silo via the loading mechanism; the discharge mechanism includes a coal discharge belt and a coke discharge belt; the coal discharge belt and the coke discharge belt are located on the extension lines of each other, and their heads are located at the two ends of the silo arrangement, respectively serving as the coal discharge end and the coke discharge end; the tail ends of both are connected to a movable tail wheel car, which has a coal discharge tail wheel and a coke discharge tail wheel corresponding to the coal discharge belt and the coke discharge belt, respectively; the material in the silo can be unloaded onto the coal discharge belt or the coke discharge belt via the unloading mechanism.

[0008] A further improvement to the above scheme is that the coal conveyor belt or coke conveyor belt has a belt counterweight.

[0009] A further improvement to the above scheme is that the bottom of the silo has two discharge ports, each of which corresponds to a set of discharge mechanisms.

[0010] A further improvement to the above scheme is that both the loading mechanism and the unloading mechanism are reciprocating unloading vehicles.

[0011] A further improvement to the above scheme is that the top of the silo has a loading port.

[0012] This invention provides a single-row, multi-silo coal and coke mixed storage and transportation system. Two parallel belt conveyors at the top of the silos feed the material, significantly reducing the risk of material mixing. Four belt conveyors at the bottom of the silos improve discharge efficiency and minimize mixing. Multiple belts can operate simultaneously, resulting in high discharge efficiency. The system utilizes a shared tail wheel car and counterweight device between two belt conveyors, resulting in a compact structure that is advantageous for equipment arrangement in the limited space at the bottom of the silos. By moving the tail wheel car, the system can quickly adapt to adjustments in the number of coal and coke bins. Attached Figure Description

[0013] The invention will now be further described with reference to the accompanying drawings.

[0017] The single-row, multi-silo coal and coke mixed storage and transportation system of this embodiment, such as Figure 1 and Figure 3 As shown, it includes: N silos 3 arranged in a row, a loading mechanism 2 located above the silos 3, and a discharging mechanism 5 located below the silos. The loading mechanism 2 loads its material into the silos through the loading mechanism 1, and the discharging mechanism 5 unloads the material in the silos onto the discharging mechanism 5 through the unloading mechanism 4.

[0018] In this embodiment, the first 13 silos are used as an example for illustration, where silos 1 to 7 are used for coal loading and silos 8 to 13 are used for coking.

[0019] The charging mechanism includes a coke charging belt 201 and a coal charging belt 202; the coke charging belt 201 and the coal charging belt 202 extend along the arrangement direction of the silos and are parallel to each other. A coke charging trolley 101 is positioned above the coke charging belt 201 and can move linearly back and forth; coke on the coke charging belt 201 enters the silo 3 through the coke charging trolley 101 from the top inlet 301 of the silo. Similarly, a coal unloading trolley 102 is positioned above the coal charging belt 202 and can move linearly back and forth; coal on the coal charging belt 202 enters the silo 3 through the coal charging trolley 102 from the top inlet 301 of the silo.

[0020] The bottom of the silo has discharge ports 302 and 303, each corresponding to a set of discharge mechanisms. This improves discharge efficiency and allows the use of the other set in case one set fails or the machine is shut down for material preparation. The two sets of discharge mechanisms have identical structures; one of them will be used as an example for explanation.

[0021] like Figure 2 As shown, the discharge mechanism includes a coal discharge belt 504 and a coke discharge belt 502. The coal discharge belt 504 and the coke discharge belt 502 are located on each other's extension lines, with their starting ends positioned at opposite ends of the silo arrangement, serving as the coal discharge end and the coke discharge end, respectively. The tail ends of both are connected to a movable tail wheel car 8, which has a coal discharge tail wheel and a coke discharge tail wheel corresponding to the coal discharge belt and the coke discharge belt, respectively. The tail wheel car 8 can move along a track 9. The track 9 is located between the starting ends of the coal discharge belt 504 and the coke discharge belt 502. The coke discharge belt 502 has a belt counterweight 10. A discharge trolley 402 is arranged below the discharge port 303 to discharge coke or coal onto the belt as needed.

[0022] Both the coal conveyor belt 504 and the coke conveyor belt 502 discharge material towards their respective starting ends. They can share a tail wheel car 8 and a counterweight 10. The tension of the counterweight 10 is transmitted to the coal conveyor belt 504 via the tail wheel car 8, tightening both the coke conveyor belt 502 and the coal conveyor belt 504 simultaneously. On-site modifications to the silo require ground-level construction to accommodate the counterweight 10 and other mechanisms. Reducing the number of counterweights significantly lowers the on-site modification costs of the silo.

[0023] Given the arrangement of the silos, their total length remains constant, but the distribution of their contents can change. For example, in this embodiment, silos 1 to 7 are used for coal, and silos 8 to 13 are used for coke. However, after several production runs, the arrangement changes to silos 1 to 5 for coal and silos 6 to 13 for coke. This necessitates changing the length of the discharge belts. In this embodiment, adjustment can be achieved simply by adjusting the lengths of the coal discharge belt 504 and the coke discharge belt 502, and by moving the tail wheel car between silos 8 to 5 and 6.

[0024] This invention is not limited to the above embodiments. All technical solutions formed by equivalent substitutions fall within the protection scope claimed by this invention.
