Abstract
Description
Technical Field
[0001] This utility model relates to a sunken storage yard structure for expanding storage capacity. It is applicable to the field of material storage and transportation technology. Background Technology
[0002] In green mining production and processing systems, material storage yards have been upgraded from traditional "temporary storage areas" to core hubs for full-process greening. In processing steps such as crushing, screening, and mineral processing, the material storage yard acts as a dynamic regulating pool, effectively addressing the rhythm differences between mining, system processing, and downstream sales. This facilitates close coupling among the three parties and promotes the harmonious development of green mines. The larger the volume of the "dynamic regulating pool," the more "elastic" the system maintains, improving the resilience of the entire mining production system. Currently, most mines use surface paving or retaining walls for material storage, with some even resorting to open-pit storage.
[0003] Traditional mine stockpiles use surface paving or retaining walls for storage, and some mines even use open-air storage, which has three main drawbacks:
[0004] Low land utilization: Land resources are particularly valuable in the mining industry, and the area available for stockpiling is limited. Traditional stockpiling methods typically involve laying materials flat on the ground or simple stacking, with materials mainly expanding horizontally, requiring a large amount of land resources. In areas with high land costs or limited space, this method is difficult to meet the needs of large-scale stockpiling, thus weakening the role of the "dynamic regulating pool".
[0005] Low space utilization: Due to limitations of the ground surface and the natural angle of repose of materials, the vertical space utilization of the storage yard is limited, resulting in low space utilization.
[0006] Poor environmental performance: Open-air storage easily causes dust pollution and environmental damage; during the rainy season, heavy rain can easily cause resource loss. Utility Model Content
[0007] The technical problem to be solved by this utility model is to provide a sunken stockpile structure that expands the stockpile capacity, in view of the above-mentioned problems.
[0008] The technical solution adopted by this utility model is: a sunken storage yard structure for expanding storage capacity, comprising:
[0009] Sunken storage yard;
[0010] At least one feeding conveyor belt is located above the sunken stockpile site, and its lower part is fixed to the sunken stockpile site by a support frame.
[0011] At least one underground passage is located below the sunken storage yard, and each underground passage has at least one unloading port above it;
[0012] A discharge conveyor belt machine is installed inside the aforementioned alleyway;
[0013] A closed enclosure to cover the sunken storage yard area;
[0014] Several fog cannons are evenly distributed within the sunken storage yard area.
[0015] The sunken storage yard includes the sunken site surface and the sunken slopes surrounding the sunken site surface.
[0016] The sunken site has a drainage slope that slopes from the center to the periphery, and a water collection ditch is provided at the toe of the sunken slope.
[0017] A steel plate mesh is installed on the water collection ditch, and graded pebbles are fully laid on the steel plate mesh.
[0018] A vibrating feeder is provided corresponding to the discharge port.
[0019] Flexible photovoltaic panels are installed on the enclosure.
[0020] The alleyways are connected by at least one safe passageway.
[0021] The beneficial effects of this utility model are: This utility model adopts a sunken storage yard, and the entire storage yard is a sunken two-, three-, four-, or circular slope, which allows the storage capacity of the silo to be increased many times within a limited area, while reducing dead volume.
[0022] In this invention, the slopes and ground of the storage yard are supported and the foundation is treated according to the geological conditions to ensure the stability of the entire storage yard and silos; the sunken storage yard type is selected according to the actual terrain to reduce the amount of excavation and filling during site leveling and reduce investment.
[0023] This utility model improves the environmental friendliness of the entire storage and transportation system by covering the sunken storage yard with a closed cover to form a closed structure. It achieves efficient use of space and energy, reduces costs and increases efficiency, and generates a highly synergistic coupling effect from the environmental, economic and technical levels, providing important support for the sustainable development of industry, warehousing and shipping.
[0024] In this utility model, the slope is designed with a uniform drainage slope and direction for the water collection ditch. A steel plate mesh is installed on the upper part of the water collection ditch, and graded pebbles are fully laid on the steel plate mesh to ensure smooth drainage of the entire storage and transportation system.
[0025] The sunken site surface of this utility model has a natural drainage slope from the middle to the bottom of the slope to ensure smooth drainage of the entire storage and transportation system.
[0026] This utility model sets up transfer tunnels below the ground of the storage yard. Each tunnel runs through the entire sunken storage yard. Each tunnel is equipped with a discharge conveyor belt, multiple unloading ports and corresponding vibrating feeders, ensuring that the entire material transfer system can transfer materials in a flexible and efficient manner according to local conditions.
[0027] This utility model allows for setting the number of tunnels in the material transfer system according to the size of the storage yard. At regular intervals between tunnels, a connecting channel with the same dimensions as the tunnel and connecting adjacent tunnels is set up, which facilitates later operation and maintenance while serving as a safety passage to improve the safety of the entire system.
[0028] This invention involves systematically installing mist cannons on the slope tops throughout the entire storage yard to improve the system's environmental friendliness and create a favorable working environment for later operation and maintenance.
[0029] In this invention, the enclosure is supported on the ground around the sunken storage yard, thereby reducing the height of the enclosure structure and saving investment. Attached Figure Description

[0039] like Figures 1-3 As shown, this embodiment is a sunken stockpile structure for expanding stockpile capacity, including a sunken stockpile site, a closed enclosure, a feeding conveyor belt (including an unloading trolley), and a discharge conveyor belt, etc.
[0040] In this embodiment, the sunken storage yard has a sunken ground surface, with sunken slopes at the front end and both sides, and a discharge ramp at the rear end. The sunken ground surface has a drainage slope sloping from the center to the perimeter. A water collection ditch is provided at the toe of the sunken slope, and a steel mesh is installed over the water collection ditch, with graded pebbles fully laid on the steel mesh.
[0041] In this example, the enclosure covers the sunken storage yard, forming a closed space that includes the sunken storage yard and is basically separated from the outside world.
[0042] In this example, two feeding conveyor belts are installed within an enclosed space. The feeding conveyor belts are located at a certain height above the sunken storage yard and are fixed to the sunken storage yard by supports below. The feeding conveyor belts extend from the front of the sunken storage yard into the sunken storage yard to transport materials to the sunken storage yard for storage.
[0043] In this embodiment, three underground passages are provided beneath the sunken site surface, extending from the front end to the rear end of the sunken site surface. The three passages are connected by a safety passage. Each passage is equipped with a discharge conveyor belt, which extends from the front end of the sunken site surface to a discharge ramp at the rear end of the sunken site surface, and then extends to the subsequent material processing area via the discharge ramp.
[0044] In this embodiment, multiple unloading ports are evenly distributed on each tunnel, and a vibrating feeder is provided for each unloading port. Materials stored on the sunken storage yard can enter the tunnel through the unloading port and fall onto the discharge conveyor belt, which then transports the materials to the subsequent processing area.
[0045] In this embodiment, fog cannons are systematically installed at the top of the sunken slope inside the enclosed space to improve the environmental friendliness of the system and create a good working environment for later operation and maintenance.
[0046] In this example, flexible photovoltaic panels are installed on the enclosure. These panels can be used to power the entire system, achieving efficient utilization of energy resources.
[0047] In this embodiment, the material is transported to the sunken stockpile site by a feeding conveyor belt for single-point or continuous unloading and stockpiling, while the mist cannon starts dust suppression.
[0048] Sunken slopes can be used as retaining walls to separate materials. The sunken site has a certain drainage slope, which collects water from the entire site into a drainage ditch set at the foot of the slope, and then the drainage ditch is used for organized drainage.
[0049] In this embodiment, the conveyor belt conveyor and vibrating feeder inside the tunnel are controlled in a coordinated manner. The control center sends stop and start commands as needed to realize material transfer.
[0050] This embodiment addresses the needs of green mines for "reducing land use, pollution, and increasing efficiency" by proposing a sunken three-dimensional stockpile. By integrating underground space development with intelligent equipment, the volume of stockpile silos can be significantly expanded, the external enclosure height can be reduced, and the environmental friendliness, safety, and storage and transportation flexibility of the stockpile silos can be guaranteed, ensuring the flexible adjustment capability of the entire system.
[0051] This embodiment provides a systematic solution for green mine stockpiles through spatial reconstruction, technology integration, and intelligent management, which combines "expansion, cost reduction, and carbon reduction." It is particularly suitable for large and medium-sized mines with scarce land resources and high environmental protection requirements, and has significant economic, environmental, and social benefits.
[0052] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
