Description

Technical Field

[0001] The present invention belongs to the technical field of docks, and in particular relates to a port closed strip bulk silo loading and unloading operation system and operation method. Background Art

[0002] The traditional method for storing bulk materials such as ore and sulfur at ports is open-air storage yards. However, these operations generate significant dust pollution and pose significant environmental risks. Cargo can easily flow into pipe trenches due to rainwater, causing significant damage and compromising cargo quality. Furthermore, open-air storage yards require large-scale wastewater treatment plants, which increases project investment and treatment costs. In response to these challenges, many bulk cargo ports have begun developing enclosed storage yards in recent years. Currently, enclosed storage yards primarily include silos, circular silos, and strip silos. Strip silos are the most widely used for storing bulk materials such as coal, ore, grain, sulfur, and fertilizer.

[0003] Currently, the cross-section of material piles arranged in closed strip silos at ports is primarily trapezoidal, resulting in a low static storage capacity that cannot meet the port's operational needs. Furthermore, the stacking and reclaiming equipment utilizes cantilevered stacking and reclaiming mechanisms, which require a significant amount of space in the track foundation area, reducing site resource utilization. In practice, multiple strip silos are often constructed to meet storage capacity requirements. However, the construction of multiple strip silos results in a large project footprint and high construction costs. Furthermore, current port storage uses unloading carts for stacking, and a small conical hopper at the bottom of the silo utilizes gravity-flowing discharge. This method is primarily suitable for grain, which has high fluidity, and is not suitable for the storage of other bulk materials with poor fluidity, including ores and fertilizers.

[0004] After searching, Chinese invention patent CN112707181A (publication date: April 27, 2021) discloses an automated packing device and system for bulk-to-container conversion, including: an onshore bulk yard for stacking and storing bulk cargo; several belt conveyors for transporting bulk cargo from the onshore bulk yard into containers, with their ends tilted upward; a flip warehouse for placing empty containers and flipping the containers so that the doors are facing upward; an induction guide channel, one end of which is connected to the flip warehouse, for transporting containers out of the flip warehouse; and a packing channel, connected to the other end of the induction guide channel; containers are transported from the flip warehouse to the packing channel via the induction guide channel, so that the door of each container is aligned with the end of the belt conveyor; after packing is completed, the container is transported out of the packing device along the packing channel. The invention provides an automated packing device and system for bulk-to-container conversion, which can optimize the port packing process and improve the connection between each process and the operating efficiency.

[0005] Chinese invention patent CN115893021A (publication date: November 21, 2022) discloses a container terminal loading and unloading operation system with logistics and warehousing functions and a method of use; wherein, the container terminal loading and unloading operation system includes a terminal front operation area, an automated yard area and a logistics and warehousing area; the terminal front operation area, the automated yard area and the logistics and warehousing area adopt a three-dimensional space layout, wherein the automated yard area and the terminal front operation area behind the land-side rail of the quay crane are both located on the second floor of the terminal, and the logistics and warehousing area is located on the bottom floor of the terminal; this application develops the three-dimensional space resources of the terminal and adopts a three-dimensional space layout for the terminal front operation area, the automated yard area and the logistics and warehousing area; thereby realizing the integration of terminal production operations and logistics and warehousing functions within the port's land area, which not only saves a large amount of land resources required for the independent construction of logistics stations outside the port, but also facilitates operations between the terminal and the logistics and warehousing, improves the processing energy efficiency of the overall logistics chain, and improves production and processing efficiency.

[0006] Chinese invention patent CN112010053A (publication date: December 1, 2020) discloses a three-dimensional automated container terminal. The container yard is divided into two layers, the lower layer includes an automated double-cantilever gantry crane and an automated horizontal transport equipment interaction area and an automated horizontal transport equipment lane. The upper layer includes an automated double-cantilever gantry crane and a container truck interaction area parallel to the container area; the terminal also includes a lower horizontal transport operation area and an upper container truck transport operation area between the terminal and the container yard. The lower horizontal transport operation area includes an interaction area between a quay crane and an automated horizontal transport equipment, an automated horizontal transport equipment parking area, and an automated horizontal transport equipment high-speed operation area. The upper container truck transport operation area includes an interaction area between a quay crane and a container truck and a container truck high-speed lane; the double-layer three-dimensional structure reduces the area occupied by the deep coastline of the terminal, can effectively utilize space, shorten the time for port collection and discharge, alleviate the traffic pressure for port collection and discharge, reduce the running distance and time for receiving and sending containers, thereby improving the terminal operation efficiency.

Step S202: The material taking device 33 scoops the bulk material 4. The hopper 3301 is in close contact with the surface of the bulk material 4. After the hopper unit scoops the bulk material 4, it is lifted to the top of the third head funnel 3303 by the transmission device and the bulk material 4 is discharged into the third head funnel 3303. Step S203: The material taking device 33 transfers the bulk material 4, and the bulk material 4 is transferred from the third head funnel 3303 to the warehouse conveyor 3306 below it, and then transferred to the port conveying device 2 below the fourth head funnel 3307 through the fourth head funnel 3307 of the warehouse conveyor 3306, completing the warehouse discharge operation of the bulk material 4.
