Description

Technical Field

[0001] This utility model relates to the field of mining technology, specifically to an underground ore recovery system. Background Technology

[0002] like Figure 1 As shown, in mineral mining operations, after mining, the ore needs to be hoisted to the surface through a shaft. During this process, when the metering hopper transports the ore into the shaft, a large amount of ore will scatter and fall due to vibration and collisions. Currently, the common method for recovering this ore that falls into the ore powder recovery channel is to manually push small ore carts. This method has significant drawbacks: firstly, manual operation requires a large amount of manpower, as workers need to frequently push the ore carts back and forth in specific areas underground, resulting in extremely high labor intensity and a significant increase in the workload of staff; secondly, manual recovery is inefficient, limited by the speed of manual handling and the amount transported at one time, making it impossible to quickly and efficiently complete the ore recovery, causing a large amount of ore to remain in the ore powder recovery channel for a long time, which not only affects the underground working environment but also wastes resources. Therefore, it is urgent to abandon this traditional manual recovery model and adopt an automated recovery method to recover the fallen ore powder, in order to reduce labor intensity, improve recovery efficiency, and achieve high efficiency and intelligence in underground ore recovery.

The belt conveyor is used to send the crushed ore into the sedimentation tank, and the conveying pump truck is connected in series with a screening machine and a filter press through a conveying pipeline to convey the slurry in the sedimentation tank. The screening machine and the filter press are located on the mining platform in the middle of the mine shaft, and a conveyor belt is also provided on the mining platform for conveying the ore processed by the filter press and screening machine into the metering hopper.

[0005] Preferably, the screening machine and the filter press are connected by a conveying pipeline. Large particles of mineral material screened out by the screening machine are fed into the conveyor belt, while small particles of mineral material are fed into the filter press.

[0008] Preferably, a water ditch is provided in the mineral powder recovery channel, which sends the slurry flowing down from the well into the sedimentation tank, and the drainage pipe of the filter press is connected to the sedimentation tank.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

Detailed Implementation

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] The underground ore recovery system provided by this utility model mainly consists of three parts: a mine structure, ore processing components, and a circulating conveying system. The components achieve efficient collaborative operation through spatial layout and pipeline connection, as detailed below:

[0015] Mine 1 and Mining Platform 14

[0016] Mine 1 is the main structure of the system, and a mining platform 14 is set up inside it. This platform is located in the middle of the mine and is used to install equipment such as screening machine 10, filter press 11 and conveyor belt 12.

[0017] Mining platform 14 has a shaft 2 and an elevator shaft 17 at each end. Shaft 2 is equipped with a skip 18 and a weighing hopper 13. The skip 18 is used to vertically transport the final processed ore to the ground, and the weighing hopper 13 is used to weigh the ore. An elevator is installed in the elevator shaft 17 for personnel and equipment access. At the same time, the conveying pipeline 9 is laid in this channel to avoid conflict with the material conveying channel.

[0018] Mineral powder recovery channel 3 and processing equipment

[0019] The bottoms of the two channels are connected to the mineral powder recovery channel 3, in which the following equipment is arranged in sequence:

[0020] Vibrating feeder 4: The feed inlet is connected to the guide plate 15, which is used to receive the ore falling from the shaft 2. The discharge port of the vibrating feeder 4 is equipped with a baffle 16. When the baffle 16 is raised, the ore enters the crusher 5 and is fed evenly through vibration. When the baffle 16 is lowered, the ore is isolated. The baffle 16 is opened and closed manually.

[0021] Crusher 5: Crushes the ore conveyed by vibrating feeder 4 to make its particle size meet the requirements of subsequent processing.

[0022] Belt conveyor 6: transports the crushed ore to sedimentation tank 8.

[0023] Sedimentation tank 8: Water is replenished inside the mineral powder recovery channel 3. The slurry flowing down from the well shaft 2 is introduced into the sedimentation tank 8. The sedimentation tank 8 separates the mineral material by sedimentation and at the same time receives the wastewater discharged from the filter press 11, realizing liquid recycling.

[0024] Conveyor pump 7: Conveys the slurry in the sedimentation tank 8 to the screening machine 10 on the mining platform 14 through the conveying pipeline 9.

[0025] Screening machine 10: Receives slurry through conveying pipe 9 and screens out large particles such as lumps and small particles such as mineral powder. Large particles fall directly into conveyor belt 12, while small particles enter filter press 11 for dewatering.

[0026] Filter press 11: Filters small granular mineral materials to separate mineral cake and wastewater. The mineral cake falls into the conveyor belt 12, and the wastewater flows back to the sedimentation tank 8 through the drainage pipe.

[0027] Conveyor belt 12: Collects the ore processed by screening machine 10 and filter press 11, conveys it to weighing hopper 13, and finally conveys it to the ground through shaft 2.

[0028] Workflow and Principles: The specific working steps of the system are as follows:

[0029] S1 Preliminary treatment of ore: The ore falling from the shaft 2 enters the vibrating feeder 4 through the guide plate 15. The vibrating feeder 4 feeds the ore evenly through vibration. The baffle 16 is opened to send the ore into the crusher 5. The crusher 5 crushes the ore. The crushed ore is then transported to the sedimentation tank 8 by the belt conveyor 6.

[0030] S2 Sedimentation and Water Replenishment: Sedimentation tank 8 allows the mineral materials to settle in the water. The wastewater discharged from filter press 11 is returned to sedimentation tank 8 through drainage pipe, realizing the recycling of water resources and reducing wastewater discharge.

[0031] S3 Classification and Conveying Process: The conveying pump truck 7 transports the settled slurry in the sedimentation tank 8 to the screening machine 10 on the mining platform 14 through the conveying pipeline 9. The screening machine 10 separates large and small particles of ore. The large particles fall directly onto the conveyor belt 12, while the small particles of ore slurry enter the filter press 11, where they are filtered under pressure to form ore cake. The ore cake then falls onto the conveyor belt 12.

[0032] S4 Centralized Mineral Material Conveying: Conveyor belt 12 conveys the screened and filtered mineral material to metering hopper 13. After weighing the mineral material, metering hopper 13 lifts it to the ground via skip 18 to complete the recycling process.

[0033] Key technical details

[0034] Pipeline layout optimization: The conveying pipeline 9 is laid along the elevator shaft passage, utilizing the passage space to avoid intersection with the material conveying path, thereby reducing pipeline wear and maintenance costs.

[0035] The vibrating feeder 4 works in conjunction with the guide plate 15: the guide plate 15 guides the ore falling from the shaft 2 to fall precisely into the feed inlet of the vibrating feeder 4, avoiding ore scattering and improving feeding efficiency.

[0036] Liquid circulation system: The sedimentation tank 8 is connected to the wastewater pipeline of the filter press 11 to realize a closed loop of "water replenishment - sedimentation - filter press - wastewater return", which reduces water consumption and meets environmental protection requirements.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
