Ore chute and mine bunker drainage treatment device

Abstract

This invention relates to the field of open-pit mine ore pass-advance development technology, specifically to a drainage treatment device for an ore pass silo. The device includes a primary screening mechanism for draining the ore silo. An outlet is fixedly installed on the front face of the ore silo, and an electrically operated barrier door is fixedly installed on the outlet. The ore silo contains a primary screening mechanism for initial screening of ore, soil, and water. The ore is placed in a perforated manner, allowing water and sediment to flow downwards, resulting in multiple separations of ore, soil, and water. This prevents long-term soaking of sediment in the ore silo, which could cause blockage at the discharge port, thus accelerating ore production efficiency. The descending soil and water are collected, precipitated, and recycled. Mechanical automatic cleaning of sludge eliminates the need for manual cleaning, reducing the workload and improving mine production efficiency.

Description

Technical Field

[0001] This invention relates to the field of open-pit mine ore pass-advance development technology, specifically to a drainage treatment device for ore pass ore bins. Background Technology

[0002] In the mining process, ore is usually transported using ore passes. However, the extracted ore is often mixed with mud or sewage, especially during the rainy season. When the ore is lowered from the ore pass to the bottom, sewage may carry mud from the ore pass to the feeder workshop or chamber, generating a large amount of sewage and polluting the working environment. Therefore, in order to ensure the orderly operation of ore production, it is necessary to drain the ore pass ore bins to prevent mud from clogging the ore pass and affecting subsequent processing work, thereby saving a lot of processing time and speeding up the efficiency of ore production.

[0003] When water seepage occurs in existing ore chutes and ore bins, the most common approach is to let it flow by gravity and then install drainage ditches around the feeder workshop or chamber, using manual cleaning to remove the stains. However, after water seepage from the chute or rainwater seeps into the lower ore bin, it tends to accumulate at the bottom of the bin, causing the mud and dust at the bottom of the bin to be soaked for a long time. This can easily lead to blockage at the unloading port. At the same time, rainwater usually flows into the feeder workshop or chamber, making the internal environment of both dirty and messy, which is not conducive to the daily maintenance and cleaning work of the staff.

[0004] Therefore, in order to solve the problem of water flowing into the crushing chamber, reduce the workload of cleaning, and improve the production efficiency of the mine, this invention provides a drainage treatment device for ore chute ore bins. Summary of the Invention

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

[0020] 1. This ore chute drainage treatment device uses a primary screening mechanism. By placing ore in the chute through a perforated design, water and silt can flow downwards from the chute, separating the ore from the soil and water in one step. This prevents water seepage from the chute or rainwater from accumulating at the bottom of the chute after seepage, which could lead to long-term immersion in mud and dust at the bottom of the chute and cause blockage at the discharge port. This, in turn, accelerates the ore production efficiency.

[0021] 2. The ore pass drainage treatment device, through the cooperation of the secondary screening mechanism and the primary screening mechanism, sorts and collects some small-sized ore pieces that have fallen, and performs secondary separation of ore, soil and water, so as to prevent some ore from falling into the sedimentation tank during the drainage process, thereby completely separating the ore from the soil and water.

[0022] 3. The ore pass drainage treatment device collects and settles the descending mud and water through the set drainage mechanism, and uses mechanical automatic cleaning of sludge to avoid manual cleaning of stains. It can also prevent mud and water from flowing into the plate feeder workshop or the chamber, ensuring that the internal environment of the two is conducive to the daily maintenance and cleaning work of the staff, while reducing the workload of cleaning work and improving the mine production efficiency.

[0023] 4. This ore pass drainage treatment device, through the coordinated use of a primary screening mechanism, a secondary screening mechanism, and a drainage mechanism, extracts the water settled in the sedimentation tank and mixes it with clean water. The mixture is then sprayed out under high pressure to clean the surface of the ore in the secondary and primary screening mechanisms. This process maximizes the removal of mud and sand from the ore pass, ensuring a clean internal environment. It also enables the recycling of waste water or rainwater, achieving both environmental and economic benefits. Attached Figure Description

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 A drainage treatment device for an ore chute includes a primary screening mechanism 4 for draining the ore chute 1. An outlet 2 is fixedly installed on the front end of the ore chute 1. An electric barrier door 3 is fixedly installed on the front end of the ore chute 1 and on the outlet 2. The primary screening mechanism 4 for the initial screening of ore, soil and water is fixedly installed inside the ore chute 1.

[0036] The primary screening mechanism 4 includes a screening section 41 fixedly installed in the ore bin 1, and a scraping section 42 is provided in the screening section 41 to repeatedly scrape mud and ore.

[0037] Please see Figure 5 , Figure 6 and Figure 7 The lower end face of the ore bin 1 is fixedly equipped with a secondary screening mechanism 5 for further screening of ore, soil and water.

[0038] The secondary screening mechanism 5 includes a ore-filtering section 51 fixedly installed on the lower end face of the ore bin 1 and connected to the screening section 41. An ore-collecting section 52 for collecting ore is slidably connected inside the ore-filtering section 51.

[0039] Please see Figure 7 , Figure 8 and Figure 9 The lower end face of the secondary screening mechanism 5 is fixedly equipped with a drainage mechanism 6 for uniformly collecting and settling mud and water.

[0040] The drainage mechanism 6 includes a sedimentation section 61 fixedly installed on the lower end face of the ore filter section 51. An extraction section 62 for adjusting the extraction height is provided on the sedimentation section 61. The extraction section 62 and the lower end face of the ore bin 1 are jointly provided with a rehydration section 63 for recycling sedimented water.

[0041] Please see Figure 3 and Figure 4 The screening section 41 includes an ore screen plate 411, a guide plate 412, a drain outlet 413, an elliptical equipment bin 414, and a first water passage plate 415. An ore screen plate 411 inclined towards the outlet 2 is fixedly installed inside the bin 1 and below its connection to the outlet 2. The surface of the ore screen plate 411 has a plurality of screen holes. A guide plate 412 is fixedly installed inside the bin 1 below and parallel to the ore screen plate 411. The surface of the guide plate 412 is arranged from left to right... The linear array has several guide channels. The front end of the guide plate 412 and the ore bin 1 together form a drain outlet 413. Elliptical equipment bins 414 are symmetrically fixedly installed on the left and right side walls of the ore bin 1 between the ore screen plate 411 and the guide plate 412. A first water-passing plate 415 is fixedly installed on the rear inner wall of the ore bin 1 between the ore screen plate 411 and the guide plate 412. The front end of the first water-passing plate 415 is fixedly connected to several first nozzles in a linear array.

[0042] In practice, ore stored in the ore bin 1 can be discharged from the outlet 2 by opening the electric barrier door 3. When some water or rainwater enters the ore bin 1, the electric barrier door 3 is closed to prevent ore from flowing out. At this time, the water will fall down the gaps between the ore particles onto the ore screen plate 411, carrying mud and sand or a small amount of ore through the screen holes of the ore screen plate 411, and finally flow onto the guide plate 412. At this time, the mud, water and some ore will flow down the guide channel. The ore descends along the inclined surface of the guide plate 412 to the drain outlet 413 and falls into the drainage channel 511. The ore is placed in the ore bin 1 through the perforation, allowing water and silt to flow down from the ore bin 1. This separates the ore from the soil and water, preventing water seepage from the chute or rainwater from seeping into the lower ore bin 1 and accumulating at the bottom of the ore bin 1. This avoids the problem of the bottom of the ore bin 1 being soaked in mud and dust for a long time, which would cause the discharge port to be squeezed and blocked. This will speed up the ore production efficiency.

[0043] Please see Figure 3 and Figure 4 The scraping section 42 includes a first motor 421, a shaft 422, a sprocket 423, a limiting elliptical ring track 424, and a scraper 425. The first motor 421 is fixedly installed in the right elliptical equipment compartment 414. The shaft 422, which penetrates the ore compartment 1, is rotatably installed between the elliptical equipment compartments 414. The output end of the first motor 421 is fixedly connected to the shaft 422. The left and right ends of the shaft 422 are both fixedly fitted with first sprockets inside the elliptical equipment compartments 414. The other end of the elliptical equipment compartment 414 is... A sprocket 423 is rotatably installed between the ore bin 1 and the first sprocket, and the sprocket 423 and the first sprocket are rotatably connected by a chain. A limiting elliptical ring track 424 is opened in the ore bin 1 at a position corresponding to the chain, and a slider is slidably installed in the limiting elliptical ring track 424. The side wall of the slider that is far apart from each other is fixedly connected to the side wall of the chain that is close to each other. A scraper 425 is fixedly installed on the side wall of the slider that is close to each other, and rubber brushes are provided at the top and bottom of the scraper 425.

[0044] In actual operation, as the mud and ore flow downwards, the first motor 421 is periodically started, causing the shaft 422 to rotate. Through the cooperation of the first sprocket and sprocket 423, the chains in the two elliptical equipment chambers 414 start to rotate at the same speed. During the rotation of the chains, the sliders slide along the limiting elliptical ring 424. At the same time, the scraper 425 between the sliders moves in the same direction as the sliders. When the scraper 425 moves to the upper end of the limiting elliptical ring 424, the rubber brush on the upper side of the scraper 425 cleans the screen holes of the ore screen plate 411 to prevent ore from getting stuck in the screen holes. When the scraper 425 moves to the lower end of the limiting elliptical ring 424, the rubber brush on the lower side of the scraper 425 scrapes the upper surface of the guide plate 412, and finally pushes the mud and sand to the drain outlet 413 so that it falls down.

[0045] Please see Figure 5 , Figure 6 and Figure 7 The ore filtering section 51 includes a drainage channel 511, drainage screens 512, guide blocks 513, baffles 514, and a second water passage plate 515. A drainage channel 511 is fixedly installed on the lower end face of the ore bin 1 at the drainage outlet 413. Several drainage screens 512, arranged in a linear array from top to bottom, are fixedly installed within the drainage channel 511. Limiting slides are provided on the front end face of the drainage channel 511 above the drainage screens 512. Rubber baffles are installed within the limiting slides to facilitate drainage. A baffle 514 is rotatably installed on the left side wall of the channel 511 and at the drainage screen 512 via a hinge. A guide block 513 is fixedly installed on the left side wall of the drainage channel 511 and below the baffle 514. A ore storage channel is fixedly installed on the outer side of several guide blocks 513. A second water passage plate 515 is fixedly installed on the inner rear side wall of the drainage channel 511 and above several drainage screens 512. Several second nozzles are fixedly connected to the front end face of the second water passage plate 515 in a linear array.

[0046] Please see Figure 5 , Figure 6 and Figure 7 The ore collection section 52 includes a second motor 521, a screw 522, a moving plate 523, and a ore pushing block 524. The second motor 521 is fixedly installed on the front end face of the drainage channel 511, and the screw 522 is rotatably installed on the front end face of the drainage channel 511. The output end of the second motor 521 is fixedly connected to the screw 522. The moving plate 523 is threadedly connected to the screw 522 through a screw hole. The ore pushing block 524 is slidably installed in the drainage channel 511 and above several drainage screens 512 through a set slide rail. The front side wall of the ore pushing block 524 and in the limiting slide rail are fixedly connected to the moving plate 523 through a set slide rod.

[0047] In practice, when silt and ore enter the drainage channel 511, the silt will fall along the drainage screen 512 and eventually pass through the drainage channel 511 into the sedimentation tank 611. The drainage screen 512, with its gradually increasing number of screens, will screen the falling ore to ensure that it is completely retained on the drainage screen 512. This will separate and collect some small pieces of ore, and perform secondary separation of ore, soil, and water. This will prevent some ore from falling into the sedimentation tank 611 during the drainage process, thus completely separating the ore from the soil and water.

[0048] When there is a certain amount of ore on the drainage screen 512, the second motor 521 is started to rotate the screw 522. The screw 522 pushes the moving plate 523 to the left along the horizontal direction of the drainage channel 511 through the screw hole. At this time, the moving plate 523 will move the pushing block 524 to the left through the slide bar. During the movement, the slide will make the pushing block 524 move along the upper end face of the drainage screen 512. In this way, the pushing block 524 pushes the ore on the drainage screen 512 to the left. When it reaches the leftmost side, the pushing block 524 will push the baffle 514 open so that the ore can slide down the guide block 513 into the ore storage channel, and the ore that has fallen in error can be collected. During this process, the rubber water-proof plate in the limiting slide will prevent mud and water from flowing out of the limiting slide. When the ore collection is completed, the second motor 521 is started in reverse so that it returns to the original position through the ore collection part 52 with the pushing block 524. Then the second motor 521 can be stopped.

[0049] Please see Figure 8 The sedimentation section 61 includes a sedimentation tank 611, a cylinder 612, a sludge discharge hole 613, and a sludge pusher 614. The sedimentation tank 611 is fixedly installed on the lower end face of the drainage channel 511, and the sedimentation tank 611 has an outlet hole at the upper end. The cylinder 612 is fixedly installed on the right end face of the sedimentation tank 611. Several sludge discharge holes 613 are distributed at the lower left end face of the sedimentation tank 611. The sludge pusher 614 is slidably installed inside the sedimentation tank 611 through a set track. The sludge pusher 614 consists of a push plate, a support rod, and a baffle plate from right to left. The right end face of the push plate is fixedly connected to the telescopic end of the cylinder 612. The support rods are all slidably connected in the sludge discharge hole 613. A rubber plate is provided on the side of the baffle plate near the sludge discharge hole 613.

[0050] In practice, when muddy water enters the sedimentation tank 611, it undergoes static sedimentation. After sedimentation, the water from the upper part is extracted and reused through the rehydration section 63. At this time, the remaining mud will settle at the bottom of the sedimentation tank 611. The cylinder 612 is activated to push the push plate of the mud-pushing support 614, causing the mud-pushing support 614 to move to the left. When the telescopic end of the cylinder 612 is fully extended, the push plate is at the far left of the sedimentation tank 611. During this process, the push plate will push the mud in the sedimentation tank 611 out through the mud discharge hole 61. 3. After extrusion, the cylinder 612 is reversed to retract the material to its original position. At this time, the baffle plate will block the mud discharge hole 613 with the rubber plate to prevent mud and water from leaking out of the mud discharge hole 613. This allows for the unified collection and sedimentation of the descending mud and water, and the sludge is automatically cleaned by machinery, avoiding manual cleaning of the stains. It also prevents mud and water from flowing into the plate feeder workshop or the chamber, ensuring that the internal environment of both is conducive to the daily maintenance and cleaning work of the staff. At the same time, it reduces the workload of cleaning work and improves the production efficiency of the mine.

[0051] Please see Figure 9 The extraction unit 62 includes a positioning ring 621, spring rods 622, a gear ring 623, a third motor 624, a moving straight tube 625, and a telescopic tube 626. The positioning ring 621 is fixedly installed on the upper end face of the sedimentation tank 611 at the outlet position. Several spring rods 622 are fixedly installed in a circumferential array inside the positioning ring 621. The gear ring 623 is rotatably installed on the upper end face of the positioning ring 621. The moving straight tube 625 is threadedly connected to the center of the gear ring 623. The telescopic ends of the several spring rods 622 contact the moving straight tube 625 through a set locking block. The third motor 624 is fixedly installed on the upper end face of the sedimentation tank 611. A gear is fixedly sleeved on the output end of the third motor 624. The gear meshes with the gear ring 623. The telescopic tube 626 is fixedly connected to the upper end face of the moving straight tube 625.

[0052] In specific operation, after sedimentation in sedimentation tank 611 is completed, when it is necessary to determine the water level to be pumped out, the third motor 624 is started to rotate the gear ring 623 through the gear. During the rotation, the spring rod 622 inside the positioning ring 621 always abuts against the moving straight pipe 625. Therefore, during the rotation of the gear ring 623, the moving straight pipe 625 can be moved up and down in the outlet hole through the thread to adjust the moving straight pipe 625 to move to the appropriate pumping height in the water. At this time, the telescopic pipe 626 can extend and retract according to the up and down movement of the moving straight pipe 625.

[0053] Please see Figure 7 The refill section 63 includes a water pump 631, a water inlet 632, a first connecting pipe 633, and a second connecting pipe 634. The water pump 631 is fixedly connected to the lower end face of the ore bin 1. The water pump 631 is fixedly connected to the water inlet 632 and the telescopic pipe 626 at the extraction end. The water pump 631 is fixedly connected to the first connecting pipe 633 and the second connecting pipe 634 at the output end. The second water passage plate 515 is fixedly connected to the output end of the water pump 631 through the first connecting pipe 633, and the first water passage plate 415 is fixedly connected to the output end of the water pump 631 through the second connecting pipe 634.

[0054] In specific operation, after the extraction unit 62 is adjusted, the water pump 631 is started to extract the water that has settled in the sedimentation tank 611 from the moving straight pipe 625 through the telescopic pipe 626. At the same time, some water can be extracted from the inlet 632 and supplied to the first connecting water pipe 633 and the second connecting water pipe 634 respectively. The mixed water enters the second water flow plate 515 through the first connecting water pipe 633, so that the second nozzle washes the ore on the drainage screen 512. At the same time, the mixed water enters the first water flow plate 415 through the second connecting water pipe 634, so that the first nozzle washes the ore in the ore bin 1 and the dirt on the guide plate 412, thus achieving secondary utilization. The surface of the ore in the secondary screening mechanism 4 and the primary screening mechanism 5 is cleaned by high pressure spraying, so as to discharge the mud and sand from the ore bin 1 to the greatest extent and protect its internal environment. This achieves the recycling of waste water or rainwater, and achieves environmental and economic benefits.

[0055] Working principle: The ore stored in the ore bin 1 can be discharged from the outlet 2 by opening the electric barrier door 3. When some water or rainwater enters the ore bin 1, the electric barrier door 3 is closed to prevent the ore from flowing out. At this time, the water will fall down the gap between the ore onto the ore screen plate 411, and at the same time carry mud or a small part of the ore through the screening section 41 and fall into the drainage channel 511.

[0056] As the mud and ore flow downwards, the first motor 421 is periodically started to clean the screen holes of the ore screen plate 411 through the scraping part 42, and scrapes mud and sand from the upper surface of the guide plate 412 and pushes it to the drain outlet 413 so that it falls down.

[0057] When silt and ore enter the drainage channel 511, they are screened by the ore filtering section 51. When a certain amount of ore is present on the drainage screen 512, the second motor 521 is started to collect the ore screened by the ore collecting section 52. After collection, the second motor 521 is started in reverse to return the ore to its original position with the pusher block 524 through the ore collecting section 52, and then the second motor 521 can be stopped.

[0058] When the muddy water enters the sedimentation tank 611, it is allowed to settle and settle in the sedimentation tank 611. After the sedimentation is completed, the moving straight pipe 625 is adjusted by the extraction part 62 to move it to a suitable extraction height in the water. Then, the water on the upper side is extracted by the rehydration part 63 to wash the ore on the drainage screen 512, the ore in the ore bin 1 and the stains on the guide plate 412. At this time, the residual mud will settle at the bottom of the sedimentation tank 611. The cylinder 612 is started to squeeze the mud out through the sedimentation part 61, and after it is pushed out, the cylinder 612 is started in reverse to return it to its original position.

[0059] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.
