Description

Technical Field

[0001] This invention relates to the technical field of ore loading and unloading at wharves, specifically to a double-linkage wharf belt conveyor ore unloading device and its modification and usage method. Background Technology

[0002] For companies using flash furnaces for smelting, most raw materials are imported from overseas, making transportation costs a significant challenge. Choosing the right ore transportation method is a primary consideration for these companies. Currently, most port-based copper smelting companies in my country rely on direct truck transport to the plant for raw materials. Some companies, considering investment returns, are increasing the construction of conveyor belt systems at the docks. However, these conveyor belt systems typically have long routes, numerous pieces of equipment, and higher metering requirements. Furthermore, the high value of the raw materials means that the accuracy of the metering system and the raw material settlement method significantly impact actual unloading. As a result, the frequency of ore transportation falls far short of expectations, preventing the project from achieving its full potential.

[0003] Existing dock conveyor belt unloading equipment, such as Figure 3 As shown, the system includes a buffer silo, a warehouse, and a multi-stage conveyor belt system. The conveyor belt system first transports the copper concentrate to the buffer silo, then transports the copper concentrate in the buffer silo to different warehouses, and finally uses a multi-stage conveyor belt system to transport the copper concentrate in the warehouse to the storage room for copper concentrate.

[0004] Existing conveyor belt unloading systems at docks rely on a single method of ore transport, resulting in low transport speeds and failing to achieve the goal of increasing transport frequency. (Invention Content)

[0009] The unloading settlement system includes multiple second discharge systems, unloading bins, and a sixth conveyor belt machine.

The raw materials are then transported to the seventh conveyor belt via the sixth conveyor belt, and finally transported to the warehouse via the eighth, ninth and tenth conveyor belts.

[0024] When the metering system of the loading port settlement system malfunctions or is under maintenance, the unloading port settlement system can be used to continue the unfinished unloading operations.

[0034] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0035] like Figure 1-3 As shown, the dual-linkage terminal belt conveyor unloading device of this embodiment includes a loading settlement system, an unloading settlement system, a multi-stage belt conveyor, and a warehouse 20.

[0036] The loading port settlement system includes multiple first discharge systems, metering systems and multi-stage conveyor belts. A first discharge system includes a first warehouse 1 and a first conveyor belt 2. The output end of the first warehouse 1 is connected to the input end of the first conveyor belt 2. The output end of the first conveyor belt 2 is connected to the input end of the second conveyor belt 3. The output end of the second conveyor belt 3 is connected to the input end of the metering system.

[0037] The unloading settlement system includes multiple second discharge systems, unloading bins 14 and a sixth conveyor belt 15. A second discharge system includes a third warehouse 11 and a transport vehicle 12. The output end of the third warehouse 11 is connected to the input end of the unloading bin 14 through the transport vehicle 12. The output end of the unloading bin 14 is connected to the input end of the sixth conveyor belt 15.

[0038] The output of the metering system and the output of the sixth conveyor belt 15 are connected to the input of the seventh conveyor belt 16. The output of the seventh conveyor belt 16 is connected to the input of the eighth conveyor belt 17. The output of the eighth conveyor belt 17 is connected to the input of the ninth conveyor belt 18. The output of the ninth conveyor belt 18 is connected to the input of the tenth conveyor belt 19. The output of the tenth conveyor belt 19 is connected to the input of the warehouse 20.

[0039] This invention adopts different ore transportation methods to meet different unloading and settlement needs, realizing bidirectional operation of the ore conveyor belt, improving the system's risk resistance, and thus improving the overall ore transportation efficiency and frequency. The dual-linkage mode can increase the frequency of ore conveyor belt use, improve equipment operating rate, reduce ore transportation costs and transshipment losses, and increase certain economic benefits. It can also reduce the amount of open-air storage in terms of raw material stacking and storage, reduce the risk of raw materials getting wet, and provide a guarantee for subsequent production and use.

[0040] Furthermore, the metering system includes multiple third discharge systems, multi-stage conveyor belts, storage bin 6, and buffer bin 7. Each third discharge system includes a fifth conveyor belt 5 and a second storage bin 10. The output end of the second conveyor belt 3 is connected to the input end of the third conveyor belt 4. The output end of the third conveyor belt 4 is connected to the input end of the buffer bin 7. The output end of the buffer bin 7 is connected to the input end of the fourth conveyor belt 9. The output end of the fourth conveyor belt 9 is connected to the input end of the second storage bin 10. The output end of the second storage bin 10 is connected to the input end of the fifth conveyor belt 5. The output end of the fifth conveyor belt 5 is connected to the input end of the storage bin 6. The output end of the storage bin 6 is connected to the input end of the seventh conveyor belt 16.

[0041] The original intermittent feeding method was changed to spiral feeding, and the number of interlock trips caused by the 10 material level in the second warehouse being too high was reduced through program adjustment, thereby improving the continuity of metering and reducing the interference of start-stop on the accuracy of system metering.

[0042] Furthermore, a loss-in-weight scale 8 is installed between the output end of the buffer chamber 7 and the input end of the fourth conveyor belt 9.

[0043] Furthermore, the first tape machine 2, the second tape machine 3, the third tape machine 4, the fifth tape machine 5, the fourth tape machine 9, the seventh tape machine 16, the eighth tape machine 17, and the ninth tape machine 18 are unidirectional tape machines, and the tenth tape machine 19 is a reversible tape machine.

[0044] Furthermore, the first tape machine 2 and the second tape machine 3 have different transmission directions, the second tape machine 3 and the third tape machine 4 have different transmission directions, the seventh tape machine 16 and the eighth tape machine 17 have different transmission directions, the eighth tape machine 17 and the ninth tape machine 18 have different transmission directions, and the ninth tape machine 18 and the tenth tape machine 19 have different transmission directions.

[0045] The distance from Warehouse 1 to Buffer Warehouse 7; Storage Warehouse 6, Unloading Warehouse 14 to Warehouse 20 is very long and has corners, requiring different conveyor belts to turn back in order to continue transporting raw materials forward.

[0046] A method for retrofitting a dual-linkage wharf belt conveyor ore unloading device, used to transform an existing wharf belt conveyor ore unloading device into a dual-linkage wharf belt conveyor ore unloading device, includes the following steps:

[0047] Step S10: Add a loss-in-weight scale 8 system below the buffer chamber 7, and change the intermittent feed to a spiral feed. Connect the output end of the buffer chamber 7 to the input end of the fourth conveyor belt 9.

[0048] Step S20: Adjust the system program to improve the continuity of metering in the second warehouse 10 and reduce the interference of start-up and shutdown on the accuracy of system metering.

[0049] In step S30, the output end of the second warehouse 10 is connected to the input end of the fifth conveyor belt 5, the output end of the fifth conveyor belt 5 is connected to the input end of the storage warehouse 6, and the output end of the storage warehouse 6 is connected to the input end of the seventh conveyor belt 16, thus forming a loading port settlement system.

[0050] This modification can prevent the metering system from being forced to shut down due to belt conveyor malfunctions, and can also improve the material balance on the seventh belt conveyor 16, reducing the failure rate of the seventh belt conveyor 16 being crushed due to uneven force.

[0051] Step S40: Add a sixth conveyor belt 15 and a discharge bin 14 to the front end of the seventh conveyor belt 16, and connect the output end of the discharge bin 14 to the input end of the sixth conveyor belt 15, and connect the output end of the sixth conveyor belt 15 to the input end of the seventh conveyor belt 16 to form a port unloading settlement system.

[0052] The sixth conveyor belt 15 and the unloading bin 14 constitute a small unloading system. Raw materials unloaded from the dock are transferred to the dock weighbridge 13 by the transport vehicle 12. After preliminary weighing, they are transported to the unloading bin 14 and unloaded onto the sixth conveyor belt 15. Subsequently, they are transported to the warehouse 20 in the plant via the seventh conveyor belt 16 of the dock's ore transport belt and subsequent systems, completing the entire unloading process.

[0053] Step S50: Construct an intelligent platform to integrate the loading port settlement system and the unloading port settlement system to form a dual-linkage control platform.

[0054] Through the above steps, a new interlocking mode was constructed, which allows for bidirectional switching of operations for different ore settlement methods, realizing the application of dual-linkage operation mode and improving the frequency and efficiency of ore conveyor belt use.

[0055] A method for using a double-linkage wharf belt conveyor for ore unloading, comprising the following method:

[0056] When the loading port settlement system is selected, the raw materials enter the first conveyor belt 2 from the first warehouse 1, and then are transported to the metering system of the ore conveyor belt through the second conveyor belt 3 and the third conveyor belt 4 for metering and transmission. Then, they fall from the storage bin 6 of the metering system into the seventh conveyor belt 16, and finally are transported to the warehouse 20 through the eighth conveyor belt 17, the ninth conveyor belt 18 and the tenth conveyor belt 19; so as to achieve efficient ore transportation without touching the ground throughout the entire process.

[0057] When the unloading settlement system is selected, the raw materials enter the transport vehicle 12 below from the third warehouse 11. The transport vehicle 12 transports the raw materials a short distance to the weighbridge 13 at the dock for weighing. Then, the raw materials are poured into the unloading bin 14 at the end of the sixth conveyor belt 15. The raw materials are then transported by the sixth conveyor belt 15 to the seventh conveyor belt 16, and finally transported to the warehouse 20 by the eighth conveyor belt 17, the ninth conveyor belt 18, and the tenth conveyor belt 19. This achieves continuous ore transportation without open-air storage.

[0058] When the metering system of the loading port settlement system malfunctions or is under maintenance, the unloading port settlement system can be used to continue the unfinished unloading operations. This avoids situations where ore transportation is interrupted due to system maintenance, effectively improves the actual efficiency of the ore conveyor belt, and enables continuous multi-batch ore transportation.

[0059] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
