Description

Technical Field

[0001] The present invention relates to the technical field of mine mining, in particular to a high-efficiency ore separation device for mine mining. Background Art

[0002] In the mining industry, the efficiency and environmental performance of ore separation equipment directly affect the utilization rate of mineral resources and the safety of the working environment. Existing ore separation equipment has the following technical bottlenecks in practical application:

[0003] Traditional ore separation equipment mostly uses a single-roller crushing structure, which achieves ore crushing through the extrusion of a single crushing roller and a fixed jaw plate. This structure has the disadvantages of uneven crushing particle size and high energy consumption. When processing ores with higher hardness, single-roller crushing is prone to material jamming, resulting in frequent equipment shutdowns. In the screening process, existing equipment generally uses a horizontally arranged single screen, relying on the ore's own gravity to fall through the screen. This plane screening method has two major disadvantages: first, fine-grained ore easily accumulates on the surface of the screen, causing the screen holes to become clogged; second, the separation path between slag and qualified ore is chaotic, and material mixing residues often appear, resulting in insufficient separation purity, making it difficult to meet the sorting needs of high-grade ores.

[0004] Existing equipment often relies on natural gravity or simple vibration motors to discharge slag. When processing ore with high moisture content or high viscosity, slag easily accumulates in the discharge channel. While some equipment utilizes high-frequency vibration for slag discharge, these lack effective buffering mechanisms. The vibration impact directly impacts the equipment frame, causing fatigue and fracture of supporting components, severe wear of key parts, and high maintenance costs. This dilemma of balancing slag discharge efficiency with equipment life has become a key factor hindering the continuous operation of ore separation equipment.

[0005] To solve the above problems, the industry urgently needs a high-efficiency ore separation equipment for mining, which can specifically overcome the technical bottlenecks of traditional equipment and provide a new solution for the green and efficient mining of mining resources.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] Roller crushing and three-dimensional screening work together to break through the efficiency bottleneck of traditional equipment

[0021] Existing technologies mostly use a combination of single-roller crushing and flat screens, which have problems such as uneven crushing particle size and screening blockage. This equipment uses a rotating motor to drive the dual extrusion crushing rollers to rotate synchronously in opposite directions, and the staggered bite of the wear-resistant crushing teeth to achieve strong extrusion and tearing crushing of the ore, significantly improving the crushing efficiency; the separation mechanism uses high and low support columns to carry inclined screen plates and slag guide plates, forming a three-dimensional "crushing-screening-diversion" process. Compared with traditional flat screening, the rate at which the ore passes through the screen plate is increased, the slag residue rate is reduced, and the overall processing efficiency is greatly improved.

[0022] Bevel gear transmission and vibration buffer design solve the problem of insufficient precision of traditional screening

[0023] Traditional screening components mostly rely on belt transmission, which has the defects of unstable vibration frequency and poor screening accuracy. The screening component of this equipment drives the active bevel gear through a rotating motor, and the transmission bevel gear drives the rotating rod and the mounting plate to rotate, and then converts the rotational motion into reciprocating movement of the axis of the screen plate through the linkage, so that the screen plate produces controllable reciprocating movement; the vibration component adopts an "eccentric drive + buffer spring" structure. The inclined protrusion of the driving plate pushes the column to make the slag guide plate vibrate at high frequency, and the buffer spring absorbs the impact at the same time. Compared with traditional rigid vibration slag discharge, it not only ensures the rapid discharge of slag, but also reduces the wear rate of equipment components, solving the contradiction between screening accuracy and equipment life in the existing technology.

[0024] Combining spray dust removal with directional airflow fills the environmental shortcomings of traditional equipment

[0025] Most existing ore separation equipment lacks an integrated dust removal system, or adopts a simple spraying method, resulting in incomplete dust control and waste of water resources. The water tank, pressure atomizing pump and atomizing nozzle of this equipment constitute a spray dust reduction system, which converts the liquid into fine water mist. Combined with the directional airflow of the fan, it forms an integrated dust removal process of "adsorption-sedimentation-discharge". The dust purification efficiency is improved compared with traditional spraying, and the water mist moistens the ore to reduce the friction between particles, thereby assisting in improving screening efficiency. Compared with traditional equipment, while achieving environmental protection standards for the operating environment, it can also improve the equipment operation stability by reducing dust accumulation, taking into account both environmental benefits and production efficiency.

DETAILED DESCRIPTION

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0034] See also Figures 1-6 As shown, the present invention provides a technical solution: an efficient ore separation equipment for mining, with a body 1 as the core carrier, deeply integrating the three functional modules of crushing, separation and dust removal. When the equipment is in operation, the ore is introduced from the top feed chute, and then the crushing assembly 2 driven by the rotating motor 11 is started, and the extrusion crushing roller 21 and the wear-resistant crushing teeth 22 work together to quickly complete the pre-crushing and transport it to the separation mechanism 4 through the conical guide frame 25. Two groups of support columns 41 with different heights firmly support the inclined screen plate 42 and the slag guide plate 43. The screening assembly 5 below the screen plate 42 drives the axis of the screen plate 42 to move back and forth for screening with the help of the rotating motor 1 52 and the bevel gear transmission. The ore quickly passes through the sieve hole and is efficiently discharged through the discharge chute on one side; the vibration assembly 6 below the slag guide plate 43 relies on the rotating motor 2 67 and the crawler 69 transmission structure to prompt the slag to quickly slide along the guide plate to the discharge chute on the other side, greatly reducing the slag residue;

[0035] At the same time, the water tank 3, the pressure atomizing pump 32 and the atomizing nozzle 33 constitute a spray dust reduction system, which cooperates with the fan 12 to directionally purify the working environment and effectively reduce dust pollution. The equipment realizes the integrated and efficient operation of the entire process of ore crushing, screening and dust removal through the precise linkage of multiple components, providing efficient and environmentally friendly ore separation solutions for the mining field.

[0036] according to Figure 1 As shown, the water tank 3, the pressure atomizing pump 32 and the atomizing nozzle 33 constitute a dust removal and auxiliary processing module of the high-efficiency ore separation equipment for mining. A liquid injection pipe is provided on the top of the water tank 3 for replenishing liquid, and the lower end is connected to the pressure atomizing pump 32 through a connecting pipe 31. The liquid level gauge monitors the water level in real time. When working, the pressure atomizing pump 32 pressurizes the liquid in the water tank 3 and transports it to the atomizing nozzle 33 arranged above the sieve plate 42 through a pipeline. The atomizing nozzle 33 converts the liquid into fine water mist. On the one hand, it effectively absorbs the dust generated during the ore crushing and screening process, cooperates with the fan 12 to achieve efficient dust removal and purify the working environment; on the other hand, the atomized liquid can wet the ore, reduce the friction between particles, assist the sieve plate 42 in screening, improve the ore separation efficiency and quality, and ensure the green and efficient operation of the equipment.

[0037] according to Figure 2 As shown, the crushing assembly 2 is a crushing unit of an efficient ore separation equipment for mining, which consists of an extrusion crushing roller 21, wear-resistant crushing teeth 22, a toothed disc 23, a chain 24 and a conical guide frame 25. The outer ends of the two extrusion crushing rollers 21 arranged in parallel at the upper end of the internal body 1 are alternately installed with wear-resistant crushing teeth 22 to enhance the crushing capacity; one end of the two rollers extends to the outside of the body, and a toothed disc 23 is installed on the surface, and is driven by a chain 24 to ensure synchronous operation. The rotating motor 11 is connected to one of the extrusion crushing rollers 21 to provide a power source. After the ore enters through the feed chute, it is quickly crushed under the squeezing and tearing action of the two rollers and the crushing teeth, and then is diverted to the subsequent screen plate 42 through the conical guide frame 25 fixedly installed below, thereby improving the overall processing efficiency of the equipment.

[0038] according to Figure 3 and Figure 4 As shown, separation mechanism 4 is the processing unit of efficient ore separation equipment used in mining, consisting of support columns 41, screen plates 42, slag deflectors 43, screening assembly 5, and vibrating assembly 6. Two sets of support columns 41, arranged at different heights, are securely mounted on the bottom surface of body 1, supporting inclined screen plates 42 and slag deflectors 43, respectively. The through-holes of screen plates 42 correspond to the through-holes of slag deflectors 43, forming an efficient screening channel.

[0039] The screening assembly 5 is mounted below the sieve plate 42. Rotating motor 1 52, through the meshing of driving bevel gear 53 and transmission bevel gear 56, drives the rotating rod 55, mounting plate 57, and linkage 58, driving the axis of the sieve plate 42 back and forth, allowing qualified ore to quickly pass through the sieve holes and be discharged through the discharge chute on one side of the machine body. The vibrating assembly 6 below the slag deflector 43 uses rotating motor 2 67 to drive a two-phase rotating shaft 68, which in turn rotates a single-phase rotating shaft 66 via a crawler 69. The inclined protrusions of the driving plate 65 push the uprights, causing the slag deflector 43 to vibrate, forcing the slag that fails to pass through the deflector plate to slide down the deflector into the discharge chute on the other side.

[0040] In addition, components such as fixed blocks 44, limiting posts 46, sliders 48, and buffer springs 49 ensure stable operation of the screen plate 42 and slag guide plate 43, reducing vibration and shock. This separation mechanism significantly improves ore separation efficiency and purity through the coordinated operation of screening and vibratory slag removal.

[0041] according to Figure 5 As shown, the screening assembly 5 is the drive unit for screening in high-efficiency ore separation equipment used in mining. It is installed at the lower end of the highest point of the screen plate 42 and consists of a connecting box 51, a support plate 54, a rotating rod 55, a transmission bevel gear 56, a mounting plate 57, and a linkage 58. The connecting box 51 is fixedly connected to the upper end of the inner side of the support column 41. The supporting plates 54 on both sides respectively mount the rotating rods 55. The inner ends of the two rods are equipped with transmission bevel gears 56, and the outer ends extend outside the support column and are fixed to the mounting plate 57.

[0042] During operation, a rotating motor 52 within the connection box 51 drives the driving bevel gear 53, which, through meshing, causes the transmission bevel gears 56 on both sides to rotate synchronously, thereby rotating the rotating rod 55 and the mounting plate 57. The positioning posts on the mounting plate 57 are flexibly engaged with the limiting posts 46 on the bottom of the sieve plate 42 via a linkage 58, converting the rotational motion into reciprocating movement along the axis of the sieve plate 42. The sieve plate 42 is tilted and has through-holes on its bottom. During movement, the ore quickly passes through the sieve holes and is discharged through a discharge chute on the side of the machine body, achieving efficient separation from the slag.

[0043] according to Figure 6 As shown, the vibration assembly 6 is the component that drives the slag deflector in the efficient ore separation equipment used in mining. It is installed at the lower end of the highest point of the slag deflector plate 43 and consists of a fixed box 61, a guide rod 62, a connecting plate 63, a buffer spring 1 64, a drive plate 65, and a single-phase rotating shaft 66. The fixed box 61 is fixed to the bottom surface of the machine body 1. The guide rod 62 inside it passes through the through hole of the box body. The upper end is connected to the connecting plate 63 on the bottom of the slag deflector plate 43. The lower end is equipped with a limit plate and connected to the buffer spring 1 64.

[0044] During operation, the rotating motor 2 67 at the lower end of the fixed box 61 drives the two-phase rotating shaft 68, which drives the single-phase rotating shafts 66 on both sides to rotate synchronously through the crawler 69, thereby rotating the driving disk 65. The inclined protrusions on the surface of the driving disk 65 fit with the columns on the limit disk, pushing the columns during rotation, causing the slag guide plate 43 to generate high-frequency vibration. Under the action of vibration, the inclined slag guide plate 43 quickly slides the slag to the discharge trough on the other side of the fuselage to avoid slag accumulation. The buffer spring 1 64 effectively absorbs the vibration impact force to ensure stable operation of the component.

[0045] The effects achieved by the entire organization are:

[0046] When the raw ore mined from the mine enters the equipment through the feed chute at the top of the fuselage 1, the operation process of the equipment is immediately started, and the rotating motor 11 installed on one side of the upper surface of the fuselage 1 starts to run, providing driving force for the crushing component 2. In the crushing component 2, two extrusion crushing rollers 21 arranged in parallel at the upper end of the fuselage 1 are driven by the toothed disc 23 and the chain 24 to achieve synchronous reverse rotation. The wear-resistant crushing teeth 22 arranged alternately at the outer end of the roller form an interlaced crushing working surface. After the ore enters the gap between the two rollers, it is quickly crushed into particles with smaller particle size under the dual action of strong squeezing and tearing of the wear-resistant crushing teeth 22. Under the action of gravity, the crushed ore slides along the inner wall of the conical guide frame 25 fixed below, which can guide the ore and transport it to the separation mechanism 4 to prepare for the subsequent fine separation link.

[0047] The separation mechanism 4 is the core part of the equipment for achieving efficient separation of ore and slag. Two groups of support columns 41 of different heights are firmly installed on both sides of the bottom surface of the fuselage 1, respectively carrying the inclined screen plate 42 and the slag guide plate 43. The through holes on the bottom surface of the screen plate 42 correspond to the slag guide plate 43, forming an orderly and efficient screening channel.

[0048] Screening components drive screening

[0049] The screening assembly 5 located below the screen plate 42 starts the working mode under the drive of the rotating motor 52. Inside the connecting box 51, the rotating motor 52 drives the active bevel gear 53 to rotate. The active bevel gear 53 and the transmission bevel gear 56 are engaged with each other to transmit power to the rotating rod 55, so that the rotating rod 55 drives the mounting plate 57 to rotate synchronously. The positioning column on the surface of the mounting plate 57 is movably connected with the limiting column 46 on the bottom surface of the screen plate 42 through the linkage 58. This connection method converts the rotational motion of the mounting plate 57 into the reciprocating movement of the axis of the screen plate 42. The screen plate 42 is tilted and has a through hole on the bottom. During the reciprocating movement, the ore slides along the inclined surface of the screen plate 42 to the corresponding discharge trough on the side of the fuselage 1, thereby completing the preliminary separation and screening of the ore.

[0050] Vibrating components for efficient slag removal

[0051] The slag that fails to pass through the screen plate 42 will fall onto the slag guide plate 43 below. At this time, the vibration component 6 installed below the slag guide plate 43 begins to work, and the rotating motor 2 67 at the lower end of the fixed box 61 is started to drive the two-phase rotating shaft 68 to rotate. The two-phase rotating shaft 68 drives the single-phase rotating shafts 66 on both sides to rotate synchronously through the crawler 69, thereby rotating the driving disk 65. The inclined protrusions on the surface of the driving disk 65 cooperate with the columns on the limit disk. As the driving disk 65 rotates, the inclined protrusions continuously push the columns, causing the slag guide plate 43 to generate high-frequency vibrations. Since the slag guide plate 43 itself has an inclined At an oblique angle, under the dual effects of vibration and gravity, the slag quickly slides along the guide plate to the discharge trough on the other side of the fuselage 1, effectively avoiding the residue and accumulation of slag inside the equipment. At the same time, the fixed block 44, the limiting column 46, the slider 48 and the buffer spring 49 in the separation mechanism 4 work together. The fixed block 44 and the limiting column 46 provide guidance and limitation for the movement of the screen plate 42, and the slider 48 and the buffer spring 49 are used to absorb the impact force generated by the vibration of the slag guide plate 43, ensuring that the screen plate 42 and the slag guide plate 43 can still operate stably under high-frequency vibration, thereby ensuring the continuous and efficient progress of the separation work.

[0052] During the entire process of ore crushing and separation, the water tank 3 is replenished with working liquid through the injection pipe on the top, and the liquid level gauge monitors the water level in the water tank in real time to ensure sufficient liquid supply. During operation, the pressure atomizing pump 32 pressurizes the liquid in the water tank 3, and the pressurized liquid is transported to the atomizing nozzle 33 installed above the sieve plate 42 through the connecting pipe 31. The atomizing nozzle 33 converts the liquid into fine water mist. This water mist plays a dual role in the ore crushing and screening process: on the one hand, the water mist can effectively absorb the raised dust particles, settle the dust, and reduce the dust content in the air; on the other hand, the water mist moistens the ore, reduces the friction between the ore particles, makes the ore easier to move on the sieve plate 42, thereby assisting the sieve plate 42 in screening and improving screening efficiency and quality. At the same time, the fan 12 continues to operate, with its outlet aligned with the sieve plate 42, generating a directional airflow, and promptly discharging the dust-laden water mist out of the equipment. It works closely with the spray dust reduction system to achieve efficient purification of the working environment and ensure stable operation of the equipment in an environmentally friendly state.
