Description

Technical Field

[0001] The present application belongs to the technical field of ore mining, and specifically is a tungsten ore mining and sorting collaborative device. Background Art

[0002] Tungsten is a widely distributed element, which is almost universally found in all kinds of rocks, but its content is low. It must be enriched through relevant geological processes to form deposits and be mined as commercial ore. Tungsten is a high-melting-point rare metal or refractory rare metal in the field of metallurgy and metal materials. Tungsten and its alloys are one of the most important functional materials in modern industry, national defense and high-tech applications. They are widely used in aerospace, atomic energy, shipbuilding, automobile industry, electrical industry, electronics industry and chemical industry. The mining of tungsten ore usually needs to be combined with the mineral processing process to improve the grade of the ore and ensure the efficient utilization of tungsten ore resources.

[0003] However, the mining and sorting of tungsten ore are usually carried out separately. The mined ore needs to be transported first and then enter a special screening device for preliminary screening and grading. This separation operation method results in low efficiency of the entire process and the inability to perform real-time screening during the mining process. Especially in underground mines, the existing mining method requires the ore to be transported from underground to the ground before screening and processing. This process is not only inefficient, but also increases transportation costs and equipment operation burdens. In addition, the existing screening devices are usually simple in structure, with fixed screens and a single screening method, and cannot flexibly cope with ores of different particle sizes. Especially when processing fine-grained ores, the screening effect is not ideal, the grading accuracy of the ore is poor, and some valuable fine-grained ores cannot be effectively separated, resulting in a waste of resources. Summary of the invention

An air box is provided outside the upper side walls of the screening bin, and the air box is connected to the nozzles. The nozzles are controlled to open and close by a control valve.

[0008] Preferably, the nozzle comprises a horizontal air outlet and an inclined air outlet, wherein the inclined air outlet is inclined downward and the inner diameter thereof becomes smaller along the air outlet direction.

[0010] Preferably, the air box comprises a plurality of air inlets, the air inlets are connected to an air pump via an air inlet pipe, and the air pump is fixed on the base and is located at the rear side of the mining machine.

[0011] Preferably, the first screen is rectangular, and first telescopic cylinders are correspondingly arranged at the four corners of the rectangle. The first telescopic cylinder is fixed to the side wall of the screening bin, and its output end contacts the bottom of the first screen to drive the first screen to vibrate up and down.

[0012] Preferably, the second screen is arranged to tilt downward, a second telescopic cylinder is fixed to the side wall of the screening bin, and an output end of the second telescopic cylinder contacts the bottom of the vibration plate to drive the second screen to vibrate up and down.

[0013] Preferably, an airbag is fixedly provided at the end of the telescopic plate located on the outer side of the vibration plate. When the telescopic plates on both sides are extended from the opening of the vibration plate, the airbags on both sides are contacted and squeezed to close the gap between the telescopic plates on both sides. When the telescopic plates on both sides are stored in the vibration plate, the airbags on both sides close the opening.

[0014] Preferably, a partition plate is fixed on the bottom plate of the screening bin, and a first sorting hopper and a second sorting hopper are arranged on both sides of the partition plate. The first sorting hopper and the second sorting hopper carry tungsten ores of different sizes, and one end of the flip plate is movably connected to the upper end of the partition plate.

[0016] The beneficial effects of the present invention are as follows:

[0017] (1) The present invention integrates tungsten ore mining and preliminary sorting functions into the same device. After mining, the tungsten ore can be directly screened in real time through a screening device without the need for additional transportation and separate processing steps, which greatly improves work efficiency and reduces equipment operating costs. Through collaborative work, mining and sorting are carried out simultaneously, simplifying the overall operating process, achieving efficient utilization of ore, and reducing resource waste.

[0018] (2) The present invention can accurately classify tungsten ore according to particle size by setting up multiple layers of screens and the combined effect of the flip plate and the sorting hopper, and separate three different sizes of tungsten ores, which enter corresponding sorting hoppers respectively. The first screen is mainly used for coarse particle screening, and the second screen is used for finer particle screening. The flip plate guides tungsten ores of different particle sizes into the corresponding hoppers, and the screening effect is significantly improved, ensuring the efficient utilization of ore resources. The vibration plate can not only promote the falling of large-particle tungsten ore, but also ensure that fine-particle tungsten ore can effectively enter the fine screen for screening by cooperating with the telescopic action of the telescopic plate.

[0019] (3) The nozzle design in the present invention greatly improves the efficiency and environmental protection effect of the screening process. The horizontal air outlet forms a wind curtain, which can effectively prevent the ore powder from drifting, reduce environmental pollution, and avoid the waste of fine-grained tungsten ore. At the same time, the inclined air outlet increases the air flow speed by reducing the inner diameter, helps the tungsten ore to move, and allows it to pass through the screen more quickly, thereby improving the screening efficiency. In particular, the inclined air outlet can blow the ore toward the telescopic plate in the second screen, so that the fine-grained tungsten ore can be further screened more accurately through the fine holes on the telescopic plate.

[0032] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0033] See also Figure 1-8 This embodiment provides a tungsten ore mining and sorting cooperative device, including a mining machine, which includes a crushing bin 1, a mobile component 2, a mining bucket 3 and a screening bin 4. The mining bucket 3 is located at the front side of the mining machine, so that the mined ore can smoothly enter the crushing bin 1 for preliminary crushing, and then enter the screening bin 4, without the need for additional conveying equipment, thereby improving the mining efficiency. A crushing roller can be set in the crushing bin 1, which is convenient for subsequent screening after preliminary crushing. The crushing bin 1 is in a detachable form. The mobile component 2 includes a base 21 and a roller 22. The base 21 provides a stable structural support for the entire device, and the roller 22 enables the mining machine to move flexibly, adapt to different mining sites, and facilitate ore mining and transportation.

[0034] See also Figure 2 and Figure 3 The screening bin 4 is fixed above the base 21. The top opening of the screening bin 4 receives the tungsten ore mined from the mining bucket 3. The screening bin 4 is the core screening part of the whole device, and the ore particle size is classified through multi-layer screening. The screening bin 4 is provided with a first screen 5, a second screen 6, a flip plate 7 and a plurality of sorting hoppers 8 from top to bottom. The first screen 5 is evenly arranged with coarse holes 51. The function of the coarse holes 51 is to screen out larger particles of tungsten ore so that smaller tungsten ore can continue to enter the second screen 6 for fine screening. The first screen 5 causes the ore to fall by vibrating action, effectively separating ores of different particle sizes. The second screen 6 includes a vibration plate 61 and a telescopic plate 62. The vibration plate 61 is a hollow plate located on both sides of the screening bin 4. One end of the vibration plate 61 is hinged to the side wall of the screening bin 4, and has a certain degree of rotational freedom. The other end is an opening. The vibration plate 61 provides the necessary vibration force during the screening process, so that the tungsten ore can pass through the second screen 6 smoothly. The telescopic plate 62 can be received in the vibration plate 61 or extended from the opening of the vibration plate 61 . Fine holes 63 are evenly arranged on the telescopic plate 62 , and are mainly used for screening finer tungsten ore particles.

[0035] See also Figure 2 and Figure 4 One end of the flip plate 7 is movably connected to the bottom of the screening bin 4. The flip plate 7 guides the tungsten ore screened by the first sieve 5 and the second sieve 6 into different sorting hoppers 8 through the left and right flipping action, ensuring that each sorting hopper 8 collects tungsten ores of different particle sizes, effectively improving the screening efficiency, reducing manual operations, and making the separation of tungsten ore more accurate.

[0036] See also Figure 5 Furthermore, a plurality of nozzles 9 are respectively provided on the upper sides of the first screen 5 and the second screen 6, and the nozzles 9 are fixed on the side walls of the screening bin 4. The nozzles 9 form a wind curtain by ejecting airflow to prevent fine ore dust from scattering during the screening process, reduce environmental pollution, and avoid waste of ore resources. The design of the nozzles 9 not only plays an environmental protection role, but also can blow the ore through the airflow to help it pass through the screen faster, thereby improving the screening efficiency.

[0037] See also Figure 3 and Figure 6Specifically, the nozzle 9 includes a horizontal air outlet 91 and an inclined air outlet 92. The design of the horizontal air outlet 91 is mainly used to form an airflow barrier to prevent fine particles and dust from drifting to the outside of the screening bin 4 during the screening process. Especially when screening tungsten ore, a large amount of powder will be generated. The airflow barrier can effectively prevent these dust from escaping and reduce environmental pollution. The design of the inclined air outlet 92 is more targeted. The inclined air outlet 92 is tilted downward, and the inner diameter becomes smaller and smaller along the air outlet direction. This reduced diameter structure increases the speed of the airflow when passing through the inclined air outlet 92, and can effectively blow larger particles of tungsten ore with greater impact force, so that it can pass through the screen smoothly, and can also avoid clogging of the screen. The inclination angles of the multiple inclined air outlets 92 on the upper side of the first screen 5 are different. Through airflows at different angles, it can ensure that the ore is evenly distributed on the screen, and further promote the effective screening of larger particles of ore.

[0038] An air box 10 is arranged outside the upper side wall of the screening bin 4, and the air box 10 is connected to the nozzle 9, and the air box 10 can provide a stable and adjustable airflow source for the nozzle 9. Through the control valve, the airflow of the nozzle 9 can be controlled according to the actual screening requirements to ensure that the screening effect of the ore on different screens is optimal. The bottom of the screening bin 4 is a non-enclosed structure, and the airflow can eventually flow out from the bottom of the screening bin 4.

[0039] The air box 10 includes a plurality of air inlets 101, which are connected to the air pump 11 through an air inlet pipe 102. The air pump 11 is fixed on the base 21 and is located at the rear side of the mining machine. The airflow provided by the air pump 11 is transported to the air box 10 through the air inlet pipe 102, and then evenly distributed to each nozzle 9 by the air box 10. This design ensures that the nozzle 9 can continue to provide a stable airflow during the screening process. The air pump 11 is located at the rear side of the mining machine, which not only avoids interference with other working parts, but also ensures that the airflow supply of the entire device is stable and efficient.

[0040] See also Figure 2 and Figure 7 The first screen 5 is rectangular and fits the shape of the screening bin 4. The four corners of the rectangle are respectively provided with first telescopic cylinders 52, which are fixed to the side wall of the screening bin 4, and the output end thereof contacts the bottom of the first screen 5. The function of the first telescopic cylinder 52 is to drive the first screen 5 to vibrate up and down through telescopic action, so that the tungsten ore moves faster on the screen surface and passes through the screen holes, especially when processing larger particles of ore, the vibration can accelerate the separation efficiency of the ore. This design avoids the accumulation of ore on the screen, improves the smoothness of screening, and reduces the blockage that may occur during the screening process.

[0041] There are four first telescopic cylinders 52 of the first screen 5. The four first telescopic cylinders 52 can perform telescopic movements simultaneously at the beginning of screening to drive the overall vibration of the first screen 5. After a period of time, the four first telescopic cylinders 52 can perform telescopic operations in sequence according to a preset order. Through this alternating vibration mode, the vibration mode of the first screen 5 is more diversified, and the screening effect is further optimized. The accumulation and blockage of ore particles can be avoided, and the screening efficiency of the first screen 5 for tungsten ores of different particle sizes is improved.

[0042] See also Figure 2 and Figure 8 The second screen 6 is arranged to tilt downward. The tilted design allows smaller particles of tungsten ore to slide down smoothly under the action of gravity, and cooperate with the vibration of the second screen 6 to enter the sorting hopper 8 after further screening. A second telescopic cylinder 64 is fixed to the side wall of the screening bin 4. The output end of the second telescopic cylinder 64 contacts the bottom of the vibration plate 61. The second screen 6 is driven to vibrate up and down through the telescopic action of the second telescopic cylinder 64.

[0043] The first telescopic cylinder 52 and the second telescopic cylinder 64 are both driven by motors. These high-frequency motors will generate a large amount of heat during operation. In order to ensure that the motors can maintain a normal operating temperature during long-term operation, the heating parts of these motors are connected to the air box 10 through a heat dissipation duct. The air flowing in the air box 10 can effectively dissipate the heat for the motors and take away the heat generated by the motors through the air flow, thereby maintaining continuous and stable operation of the equipment.

[0044] The end of the telescopic plate 62 located outside the vibration plate 61 is fixedly provided with an airbag 65, which is a closed structure and filled with gas. When the telescopic plates 62 on both sides extend from the opening of the vibration plate 61, the airbag 65 closes the gap between the telescopic plates 62 on both sides by contact and compression, preventing ore or dust from overflowing from the gap, ensuring the screening effect. When the telescopic plate 62 is stored in the vibration plate 61, the airbags 65 on both sides will also close the opening of the vibration plate 61, effectively preventing dust or other impurities from entering the opening of the vibration plate 61, keeping the inside of the equipment clean, and also limiting the storage position of the telescopic plate 62, ensuring that the telescopic plate 62 can remain stable when stored.

[0045] During the storage process of the telescopic plate 62, the feed hole 42 is opened, so that the tungsten ore that has not passed through the fine hole 63 on the telescopic plate 62 can fall smoothly. Since the telescopic plate 62 is arranged at an angle, the friction between it and the ore is small, which is conducive to the sliding of the tungsten ore and also more convenient for the smooth storage of the telescopic plate 62. In addition, the movement of the telescopic plate 62 can be driven by the motor to pull the traction rope to achieve its telescopic operation. In this embodiment, there is no specific limitation on this implementation method. As long as the telescopic movement of the telescopic plate 62 can be achieved, any driving method with this function can be adopted.

[0046] A partition plate 41 is fixed on the bottom plate of the screening bin 4, and the partition plate 41 divides the lower space of the screening bin 4 into two parts. A first sorting hopper 81 and a second sorting hopper 82 are respectively arranged on both sides of the partition plate 41, and the first sorting hopper 81 and the second sorting hopper 82 are used to carry tungsten ores of different sizes. Tungsten ores of different particle sizes separated by the screen can enter the two sorting hoppers respectively, ensuring that the screened ores can be effectively classified and stored. One end of the flip plate 7 is movably connected to the upper end of the partition plate 41. The design of the flip plate 7 enables it to be flexibly flipped at different angles, thereby guiding the screened tungsten ore to fall into the first sorting hopper 81 or the second sorting hopper 82 respectively. This design simplifies the ore diversion process, reduces manual operations, and improves the overall sorting efficiency.

[0047] Feed holes 42 are respectively provided on the upper side of the first sorting hopper 81 and the second sorting hopper 82. The feed holes 42 are located on the lower side of the second screen 6. The area of ​​the feed holes 42 is the same as the downward projection area of ​​the telescopic plates 62 on both sides after they are extended. Regardless of the state of the telescopic plates 62, the tungsten ore can smoothly pass through the feed holes 42 and fall into the hopper. In order to control the flip angle of the flip plate 7, stop plates 43 are provided on both sides of the feed hole 42. The stop plates 43 play a role in limiting the flip angle of the flip plate 7, ensuring that the flip plate 7 guides the tungsten ore into the hopper at a suitable angle without deviation or wrong guidance.

[0048] See also Figure 2 and Figure 4, the coordination process of the second screen 6, the flip plate 7 and the sorting hopper 8 is that when the flip plate 7 is located on the left, the telescopic plate 62 is in an extended state, and the tungsten ore enters the feed hole 42 through the fine hole 63 on the telescopic plate 62. Due to the angle and position of the flip plate 7, the ore slides along its inclined surface and finally enters the second sorting hopper 82 on the right. In this process, the fine particles of tungsten ore are screened through the fine hole 63 and are diverted through the feed hole 42 under the action of gravity. Subsequently, when the flip plate 7 is located on the right, the telescopic plate 62 is in a storage state, and the larger particles of ore that have not passed through the fine hole 63 will directly enter the feed hole 42, slide along the surface of the flip plate 7, and finally fall into the first sorting hopper 81 on the left. The left and right switching of the flip plate 7 can control the flow direction of ores of different particle sizes, and can ensure that the ore enters the corresponding sorting hopper according to the particle size, thereby achieving accurate sorting. When the first sorting hopper 81 and the second sorting hopper 82 are filled with tungsten ore, they can be taken out and replaced with new empty hoppers through a simple replacement operation, ensuring the continuity of the sorting process and preventing equipment shutdown or sorting interruption due to full hoppers.

[0049] The mining machine in this embodiment is specially used in underground mines and can perform preliminary screening while mining tungsten ore. In the underground mine mining stage, the mining machine can directly perform preliminary crushing and screening on the mined tungsten ore. In the underground mine, the crushing and screening accompanied by the mobile mining process can be preliminarily classified based on the size of the ore, which is helpful for the later use of more accurate methods, such as X-rays, image recognition and other methods for further screening, thereby reducing the burden of subsequent ore processing, so that the ore classification can be achieved in underground operations, avoiding the traditional step of transporting unscreened ore to the ground for secondary processing, and greatly improving the operation efficiency under the mine. In this embodiment, the movement of the mining machine not only serves as a carrier for transportation and mining, but also can provide additional vibration force for the screening process. During the driving process of the mining machine, the contact between the vehicle and the ground produces natural vibrations, which can be combined with the vibrating screen in the screening device, and the vibration of the screen is assisted by the movement of the vehicle to promote the screening of tungsten ore. This design that utilizes vehicle vibration is particularly suitable for use in rugged mining areas. The travel speed and road conditions will also have a certain impact on the screening effect. Therefore, the screening effect can be further optimized by automatically adjusting the vibration frequency of the screen and the travel speed. In addition, the vibration of the screening device and the movement of the telescopic cylinder can be directly driven by the mining machine's own power system (such as a hydraulic or electric system), reducing the need for independent motors and optimizing energy consumption configuration. For example, the hydraulic system of the mining machine can provide driving force for the first telescopic cylinder 52 and the second telescopic cylinder 64. In order to further improve the sustainability of the equipment, the power system of the mining machine can be equipped with an on-board power generation device, which uses the kinetic energy recovered from the operation of the vehicle to provide power supply for the screening device.

[0050] In this embodiment, the larger particles of tungsten ore that fail to pass through the first screen 5 can be collected and processed in a variety of ways. For example, a push plate mechanism is designed for automatic cleaning. After the screening is completed, the push plate moves along the surface of the first screen 5 to push the larger particles of ore that have not passed to one side of the screening bin 4 and then to the collection bin. The first screen 5 can also be designed as a hoistable structure. After the screening work is completed, the first screen 5 is lifted from the screening bin 4 by a lifting device and dumped into a designated ore collection area or conveyor belt. The ore remaining on the first screen 5 can be smoothly discharged from the screening bin 4, avoiding the accumulation of a large amount of ore on the screen 5, which affects the subsequent screening work.

[0051] In summary, the present invention provides a tungsten mining and sorting collaborative device, which realizes the collaborative work of tungsten mining and sorting through the combination of vibration screening, airflow assistance and sorting hopper. The mining machine cooperates with the mobile component 2 and the mining hopper 3 to seamlessly connect the mining and screening processes of tungsten ore. The first screen 5 and the second screen 6 in the screening bin 4 realize accurate screening of ores of different sizes through vibration. The airflow set by the nozzle 9 can not only prevent the diffusion of ore dust, but also accelerate the screening of ore through airflow, especially by using the cooperation of the horizontal air outlet 91 and the inclined air outlet 92, so that the tungsten ore can be fully separated during the screening process. The design of the sorting hoppers 81 and 82 ensures the efficient collection of ores of different particle sizes, and the flexible adjustment of the flip plate 7 further improves the accuracy and efficiency of sorting. In addition, through the simple hopper replacement mechanism, the sorting process can be carried out continuously without interruption due to full hopper loading.

[0052] The technical solution of the present invention has significant industrial application value in the field of tungsten mining and sorting. By effectively integrating the mining and sorting processes, the time and cost of traditional separation operations are reduced, and production efficiency is greatly improved. In addition, the design of airflow-assisted screening and hopper replacement enables the device to maintain stable operation in a high-intensity, continuous operating environment, which is particularly suitable for large-scale ore mining operations. This collaborative working mode not only improves the utilization rate of tungsten ore resources, but also conforms to the industry trend of green environmental protection, and can promote the mining industry to develop in the direction of high efficiency and environmental protection.
