Description

Technical Field

[0001] The invention relates to the technical field of mineral material processing, in particular to a centralized processing device for mine output waste. Background Art

[0002] In today's mining industry, with the continuous development and utilization of mineral resources, the problem of waste treatment has become increasingly prominent, and has become one of the key factors restricting the sustainable development of mines and environmental protection. The mining process will produce a large amount of waste, which has complex and diverse components, including ore particles of different sizes, dust and sand, and may contain a variety of heavy metals and other harmful substances. Traditional waste treatment methods often have many disadvantages and are difficult to meet the needs of modern mining production.

[0003] On the one hand, in the past, many mines did not pay enough attention to the treatment of waste, and the treatment methods were relatively simple and extensive. Usually, the waste was simply piled up or landfilled, which not only occupied a large amount of land resources, but also caused serious pollution to the surrounding soil, water and air environment. Harmful substances such as heavy metals in the waste will seep into the soil and groundwater with the erosion of rainwater, causing the soil fertility to decline and the water quality to deteriorate, posing a threat to the ecosystem and human health. At the same time, waste dumps may also cause dust and other problems, affecting the air quality and the living environment of surrounding residents.

[0004] On the other hand, from the perspective of resource utilization, traditional treatment methods have failed to fully tap the potential value of waste. Mine waste actually contains a large number of recyclable resources, such as useful minerals in ores, reusable metals, etc. However, due to the lack of effective separation and recycling technology, these resources are often wasted, which not only causes huge resource losses, but also does not conform to the concept of sustainable development. Summary of the invention

[0011] A plurality of partitions are fixedly connected to the interior of the particle bin, and the plurality of partitions divide the interior of the particle bin into a plurality of particle cavities, and the interior of the particle cavities is filled with magnetic particles.

[0012] The dustproof component comprises a guide plate, the guide plate is fixedly connected to one side of the inner wall of the dust collecting channel, and the outer wall of the guide plate is connected to a dustproof net.

[0013] The interior of the dust collecting bin is slidably connected with an arc cage, the interior of the arc cage is equidistantly and fixedly connected with a plurality of geotextile filters, and a closed door is provided on one side of an outer wall of the dust collecting bin.

[0014] Both ends of the outer wall of the cross bar are rotatably connected with rollers, and the two rollers are respectively slidably connected to the inside of the slide groove plate and the empty groove.

[0015] The bottom of the recovery bin is fixedly connected with a slideway, and the mineral collection bin and the heavy metal collection bin are slidably connected inside the slideway.

[0016] Working principle: The elevator adopts a bucket lifting device. The motor drives the bucket on the chain or belt to circulate. When the bucket moves to the bottom of the mine, the waste is loaded into the bucket by hooking. Then, as the chain or belt rotates, the bucket is lifted to the height of the processing bin. After reaching the designated position, the waste is unloaded into the processing bin, realizing the efficient lifting and transmission of the waste from the bottom of the mine to the processing bin. The servo motor drives the fixed rod to rotate, and the multiple orifice plates on the fixed rod rotate accordingly. Orifice plates with different apertures separate the processing bin into multiple grade bins and dust collection bins. When the ore waste enters the processing bin, the larger particles of waste cannot pass through the orifice plate with a smaller aperture and will be blocked in the corresponding bin; the smaller particles of waste can pass through the orifice plate with a larger aperture and enter the next bin or dust collection bin, thereby realizing the classification of the ore waste according to the volume size. The surface of the orifice plate is set at an angle. Under the action of the ore waste's own gravity and the rotation in the processing bin, the waste will accumulate along the inclined surface of the orifice plate toward the discharge port, which is convenient for subsequent discharge operations. The micro motor drives the driving wheel to rotate, and the driving wheel meshes with the saw teeth on the baffle. When the classified waste needs to be discharged, the micro motor works to drive the driving wheel to rotate, and through the transmission of the saw teeth, the baffle slides through the T-block in the connecting frame. The movement of the baffle controls the opening and closing degree of the discharge port, so that the outflow speed and flow rate of the waste can be accurately adjusted according to the actual processing needs. The particle bin is divided into multiple particle cavities by multiple partitions, and each particle cavity is filled with magnetic particles of different particle sizes for adsorbing heavy metals in the ore waste. The up and down movement of the baffle controls different discharge ports to be in an open state. When the baffle moves downward, under the action of the grading mechanism in the processing bin, ore waste of different sizes are distributed to different grade bins, and the movement of the baffle opens the discharge port at the top. At this time, larger pieces of waste fall into the recovery bin. As the baffle moves downward, one end of the extension rod moves downward accordingly, and the transmission shaft fixedly connected to the other end of the extension rod drives the inclined plate to rotate with the middle bearing shaft as the fixed point. The empty slot at the other end of the inclined plate is slidably connected to the crossbar, and the crossbar is connected to the arc plate through the L-shaped rod, thereby pushing the arc plate to move left and right to open different particle chambers. When the baffle controls the larger pieces of waste to fall into the recycling bin, the arc plate moves to open the first opened particle cavity, and the particles filled inside are larger in diameter, which can react and adsorb the heavy metals on the surface of the larger pieces of waste; as the baffle continues to slide, the volume of waste released from the discharge port gradually decreases, and the extension rod continues to drive the inclined plate to rotate, so that the arc plate opens the subsequent particle cavity, and the particles released inside also gradually decrease, so that the particles can react with the appropriate volume of waste, improving the adsorption effect of heavy metals in waste of different sizes. A servo motor 2 is fixed on the support frame on one side of the outer wall of the recycling bin, which drives the mixing bin to rotate. When the waste with magnetic particles adsorbed with heavy metals enters the mixing bin, the electromagnet fixedly connected to one side of the inner wall of the mixing bin is energized to generate a strong magnetic field, which further enhances the adsorption force on the magnetic particles and ensures that the heavy metals are separated from the waste more thoroughly.At the same time, the rotation of the mixing bin can make the waste material and the magnetic particles fully mixed, improve the adsorption efficiency, and tightly adsorb the magnetic particles on the inner wall of the mixing bin, so as to facilitate the subsequent collection and treatment of the separated heavy metals. The bottom of the recovery bin is fixedly connected with a slideway, and the mineral collection bin and the heavy metal collection bin are slidably connected on the slideway. The waste material processed by the mixing bin, the mineral material and the magnetic particles adsorbed with heavy metals are separated under specific process conditions. For example, through a specific magnetic field separation method, the attraction of the magnetic field to the magnetic particles is utilized to separate the mineral material and the magnetic particles. The separated mineral material falls into the mineral collection bin, and the magnetic particles adsorbed with heavy metals can be further processed to extract the heavy metals, and the remaining magnetic particles can be recovered or processed to achieve the classified collection of mineral materials and heavy metals.

[0017] The present invention provides a centralized processing device for waste produced by mines. It has the following beneficial effects:

[0018] 1. The present invention uses a grading mechanism to grade the waste by volume, and the magnetic particles in the particle bin in the recycling mechanism are released accordingly according to the size of the waste, thereby achieving a precise match between the waste and the particle diameter. When a larger piece of waste falls into the recycling bin, the magnetic particles with a larger particle size first react and adsorb heavy metals on the surface of the waste. As the volume of the waste gradually decreases, the particle cavity that is subsequently opened releases particles with a gradually decreasing size for adsorption. This precise matching method greatly improves the adsorption efficiency and effect of heavy metals in wastes of different sizes, ensuring that wastes of each size can contact magnetic particles with the most suitable particle size, so that heavy metals and wastes are more fully separated, reducing the residue of heavy metals in the mineral material, and improving the purity and quality of resource recovery.

[0019] 2. The present invention connects the dust collection net with the level bin, and the air pump generates negative pressure to collect dust and sand, thereby realizing the preliminary separation of dust and sand from ore waste, reducing the pollution of dust and sand to the environment and the wear of equipment. The dust and sand generated in each link of ore waste treatment can be collected in time, improving the working environment and extending the service life of the equipment, especially for some precision processing components, reducing the impact of dust and sand on their accuracy and performance.

[0020] 3. The present invention automatically controls the opening of the particle chamber according to the waste discharge situation through the linkage of baffles, extension rods, inclined plates and other components, so that the magnetic particles and the waste processing flow are closely coordinated, and the automation and efficiency of the entire recycling process are improved. The need for manual intervention is reduced, the operating error is reduced, and it is ensured that the magnetic particles contact the waste at the right time and adsorb heavy metals.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Please see attached Figure 1 -Attached Figure 8The embodiment of the present invention provides a centralized processing device for mine waste, including a processing bin 1, a hoist 2 is fixedly connected to one side of the outer wall of the processing bin 1, which is used for lifting and transporting ore waste, a grading mechanism is arranged inside the processing bin 1, which performs volume grading on the ore materials, a dust collecting mechanism for collecting dust is fixedly connected to one side of the outer wall of the processing bin 1, a discharge port 3 is opened on one side of the outer wall of the processing bin 1, one end of the discharge port 3 is connected to the grading mechanism, and the other end of the discharge port 3 is connected to a recovery mechanism for collecting heavy metals in the ore waste, and the other end of the recovery mechanism is respectively connected to a ore collection bin 4 and a heavy metal collection bin 5.

[0032] The grading mechanism includes a servo motor 6, which is fixedly connected to one side of the inner wall of the processing bin 1, and the output end of the servo motor 6 is fixedly connected to a fixed rod 7, and the outer wall of the fixed rod 7 is equidistantly fixedly connected to a plurality of orifice plates 8, and the plurality of orifice plates 8 divide the processing bin 1 into a plurality of grade bins 9 and a dust collecting bin 10, and the discharge port 3 is respectively connected to the corresponding grade bins 9, and a connecting frame 11 is fixedly connected to one side of the outer wall of the discharge port 3, and a T-block 12 is slidably connected to the inside of the connecting frame 11, and a baffle 13 is fixedly connected to one side of the outer wall of the T-block 12, and a sawtooth 14 is provided on one side of the outer wall of the baffle 13, and a micro motor 15 is fixedly connected to one side of the outer wall of the connecting frame 11, and a driving wheel 16 is fixedly connected to the output end of the micro motor 15, and the driving wheel 16 is meshed with the sawtooth 14;

[0033] Specifically, during the lifting process, the motor of the elevator 2 drives the bucket elevator to operate, and the waste is continuously transported upward by hooking. The bucket elevator 2 circulates through the buckets on the chain or belt, loads the waste from the bottom into the bucket, and then lifts it to the height of the processing bin 1 as the chain or belt rotates, and then unloads the waste into the processing bin 1. The servo motor 6 drives the fixed rod 7 to rotate, thereby driving the multiple orifice plates 8 on the fixed rod 7 to rotate. The orifice plates 8 of different sizes can sort the ore waste entering the processing bin 1 according to the volume. The waste is graded by size. Larger particles of waste cannot pass through the orifice plate 8 with a smaller aperture and will be blocked in the corresponding grade bin 9; smaller particles of waste can pass through the orifice plate 8 with a larger aperture and enter the next grade bin 9 or dust collecting bin 10. The discharge port 3 is connected to the corresponding grade bin 9, and the surface of the orifice plate 8 is inclined. The ore waste accumulates toward the discharge port 3 during operation. When the classified waste needs to be output, the micro motor 15 drives the driving wheel 16 to rotate, and the driving wheel 16 meshes with the saw teeth 14 on the baffle 13, driving the baffle 13 to pass. The T-block 12 in the connecting frame 11 slides to control the opening and closing degree of the discharge port 3, so that the outflow speed and flow rate of the waste can be adjusted according to the actual processing needs. The dust collecting mechanism is mainly used to collect dust and sand generated during the processing process. When the waste in the processing bin 1 generates dust and sand during the classification process or other operations, the air pump 19 is started to generate negative pressure. Under the action of the negative pressure, the dust and sand enter the dust collecting channel 17 through the dust collecting net 18. The aperture of the dust collecting net 18 is usually designed to be small, which can effectively prevent larger particles of waste from entering the dust collecting channel. 17, while allowing fine dust to pass through, the movement of the arc plate 24 can control the outflow or other operations of the magnetic particles 37 in the particle bin 21, and the magnetic particles 37 in the particle bin 21 separate the heavy metals from the waste by forming chemical bonds with the heavy metal ions. The waste after being processed by the recycling mechanism, the mineral materials and the magnetic particles 37 containing heavy metals therein enter the mineral material collection bin 4 and the heavy metal collection bin 5 respectively, and the mineral material collection bin 4 and the heavy metal collection bin 5 can classify and collect different materials to facilitate subsequent processing and utilization.

[0034] The dust collecting mechanism includes a dust collecting duct 17, which is provided on the outer wall of the processing bin 1, and a plurality of dust collecting nets 18 are provided at equal intervals inside the dust collecting duct 17, and the plurality of dust collecting nets 18 are respectively connected to the corresponding level bins 9, and one end of the dust collecting duct 17 is connected to the dust collecting bin 10, and an air pump 19 is fixedly connected to the outer wall of the dust collecting duct 17, and a dustproof component is fixedly connected to the input end of the air pump 19, and the dustproof component is fixedly connected to the inner wall of the dust collecting duct 17, and the output end of the air pump 19 extends along the inner bottom wall of the dust collecting duct 17;

[0035] The dustproof assembly includes a guide plate 44, which is fixedly connected to one side of the inner wall of the dust collecting channel 17, and the outer wall of the guide plate 44 is connected to the dustproof net 43;

[0036] The dust collecting bin 10 is slidably connected to an arc cage 38, and a plurality of geotextile filters 39 are fixedly connected to the inside of the arc cage 38 at equal intervals. A closed door 40 is provided on one side of the outer wall of the dust collecting bin 10.

[0037] Specifically, the dust collecting duct 17 is opened on the outer wall of the processing bin 1, and its main function is to serve as a channel for collecting dust. Its position design is convenient for connecting with each level bin 9 and the dust collecting bin 10 in the processing bin 1. When the ore waste is processed in the processing bin 1, the generated dust can enter the dust collecting duct 17 through the dust suction net 18. The function of the dust suction net 18 is to allow the dust to pass through and block larger ore particles from entering the dust collecting duct 17. When the air pump 19 is working, negative pressure is generated in the dust collecting duct 17. Due to the existence of negative pressure, The air in the level bin 9 will carry the dust and sand to the dust collection net 18. The pore size of the dust collection net 18 is small, which can allow fine dust and sand particles to pass through, while the larger ore waste particles are blocked in the level bin 9, thereby achieving the preliminary separation of dust and sand from ore waste. The guide plate 44 is fixedly connected to one side of the inner wall of the dust collecting duct 17. Its main function is to guide the flow direction of the airflow. When the dust-laden air enters the dust collecting duct 17, the guide plate 44 can make the airflow flow in a predetermined direction to avoid the airflow from generating vortices or The outer wall of the guide plate 44 is connected to a dustproof net 43, which further filters the dust-laden air. It can block some fine impurities or dust particles that may pass through the dust suction net 18, preventing these impurities from entering the air pump 19 and causing damage to the air pump 19. The interior of the dust collecting bin 10 is slidably connected to an arc cage 38, and the interior of the arc cage 38 is equidistantly fixedly connected to a plurality of geotextile filters 39. When the dust-laden air enters the dust collecting bin 10 from the dust collecting duct 17, the arc cage 38 and the geotextile filter 39 filter the dust. For further filtration and separation, the geotextile filter 39 has a certain pore structure and filtration accuracy. It can perform graded filtration according to the size of the dust particles, and collect dust of different particle sizes in different areas of the arc cage 38 or on different layers of the geotextile filter 39. When a certain amount of dust accumulates in the dust collecting bin 10, the closed door 40 can be opened and the dust can be cleaned out using corresponding tools or equipment, and then the cleaned dust can be further processed, such as recycling and environmental protection treatment.

[0038] The recycling mechanism includes a recycling bin 20, which is arranged on one side of the outer wall of the processing bin 1, and a particle bin 21 is fixedly connected to one side of the outer wall of the recycling bin 20, and a slide plate 22 is fixedly connected to one side of the outer wall of the particle bin 21, and an L-shaped rod 23 is slidably connected inside the slide plate 22, one end of the L-shaped rod 23 is fixedly connected to an arc plate 24 slidably connected to the outer wall of the particle bin 21, and the other end of the L-shaped rod 23 is rotatably connected to a cross bar 25, one side of the outer wall of the baffle 13 is fixedly connected to one end of an extension rod 26, and the other end of the extension rod 26 is fixedly connected to a transmission shaft 27, one side of the outer wall of the recycling bin 20 is fixedly connected to a middle bearing shaft 28, and one end of the outer wall of the middle bearing shaft 28 is rotatably connected to an inclined plate 29, one end of the inclined plate 29 is rotatably connected to a transmission shaft 27, and the other end of the inclined plate 29 is provided with an empty slot 30, and the cross bar 25 is slidably connected inside the empty slot 30;

[0039] The bottom of the recovery bin 20 is fixedly connected with a slideway 42, and the mineral collection bin 4 and the heavy metal collection bin 5 are slidably connected inside the slideway 42;

[0040] Both ends of the outer wall of the crossbar 25 are rotatably connected with rollers 41, and the two rollers 41 are slidably connected to the inside of the slide plate 22 and the empty slot 30 respectively;

[0041] A support frame 31 is fixedly connected to one side of the outer wall of the recovery bin 20, a servo motor 32 is fixedly connected to the interior of the support frame 31, a mixing bin 33 is fixedly connected to the output end of the servo motor 32, and an electromagnet 34 is fixedly connected to one side of the inner wall of the mixing bin 33;

[0042] A plurality of partitions 35 are fixedly connected to the interior of the particle bin 21, and the plurality of partitions 35 divide the interior of the particle bin 21 into a plurality of particle cavities 36, and the interior of the particle cavities 36 is filled with magnetic particles 37;

[0043] Specifically, the particle bin 21 is fixed to one side of the outer wall of the recovery bin 20, and the interior is divided into a plurality of particle cavities 36 by a plurality of partitions 35. Each particle cavity 36 is filled with magnetic particles 37 of different particle sizes for adsorbing heavy metals in the ore waste. The up and down movement of the baffle 13 respectively opens different discharge ports 3. When the baffle 13 moves downward, the uppermost discharge port 3 opens, and at this time, larger pieces of waste will fall into the recovery bin 20. This is because under the action of the grading mechanism in the processing bin 1, ore wastes of different sizes are distributed to different grade bins 9, and the movement of the baffle 13 controls the connection between the discharge port 3 and the different grade bins 9. As the baffle 13 moves downward, one end of the extension rod 26 also moves downward, and the extension rod 2 The other end of the arc plate 24 is fixedly connected to the transmission shaft 27. When the extension rod 26 moves, the transmission shaft 27 is driven to move. The transmission shaft 27 is rotatably connected to one end of the inclined plate 29, and the other end of the inclined plate 29 is rotatably connected to one side of the outer wall of the recovery bin 20 through the middle bearing shaft 28. Therefore, when the transmission shaft 27 moves, the inclined plate 29 is rotated with the middle bearing shaft 28 as a fixed point. The movement of the arc plate 24 is used to open different particle chambers 36. When the baffle 13 controls larger pieces of waste to fall into the recovery bin 20, the arc plate 24 moves to open the first opened particle chamber 36. The particles filled inside have a larger diameter. These larger particle size magnetic particles 37 can react and adsorb heavy metals on the surface of larger pieces of waste. As the baffle 13 continues to slide, the discharge port 36 is opened. The volume of the released waste material gradually decreases. At this time, the extension rod 26 continues to drive the inclined plate 29 to rotate, so that the arc plate 24 opens different particle chambers 36. The particles released inside these subsequently opened particle chambers 36 also gradually decrease, so that the particles can react with the waste material of appropriate volume, thereby improving the adsorption effect of heavy metals in waste materials of different sizes. When the waste material with magnetic particles 37 adsorbed with heavy metals enters the mixing bin 33, the electromagnet 34 is energized to further enhance the adsorption force of the magnetic particles 37, ensuring that the heavy metals are separated from the waste material more thoroughly. At the same time, the rotation of the mixing bin 33 can make the waste material and the magnetic particles 37 fully mixed, thereby improving the adsorption efficiency. During the rotation of the mixing bin 33, the electromagnet 34 generates a strong magnetic field to The particles 37 are tightly adsorbed on the inner wall of the mixing bin 33, which is convenient for the subsequent collection and treatment of the separated heavy metals. The bottom of the recovery bin 20 is fixedly connected with a slide 42, and the mineral collection bin 4 and the heavy metal collection bin 5 are slidably connected inside the slide 42. The waste material processed by the mixing bin 33, the mineral material and the magnetic particles 37 adsorbed with heavy metals are separated under specific process conditions, and the separated mineral material falls into the mineral material collection bin 4, and the magnetic particles 37 adsorbed with heavy metals can be further processed to extract the heavy metals, and the remaining magnetic particles 37 can be recovered or processed. The heavy metal collection bin 5 separates the mineral material and the magnetic particles 37 through a specific magnetic field separation method, thereby realizing the classified collection of the mineral material and heavy metals.

[0044] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
