Description

Technical Field

[0001] The present invention relates to the technical field of ore screening, and particularly relates to an intelligent three-axis elliptical vibrating screen. Background Art

[0002] A vibrating screen is one of the most critical mechanical equipment in the ore mining and processing industry and is an essential component in the entire production line. It separates particles of different particle sizes by vibration on a porous working surface (screen mesh), thereby realizing the screening of ores, and is divided into single-axis vibrating screens, two-axis vibrating screens, and three-axis vibrating screens. The three-axis elliptical vibrating screen mainly consists of three axial vibrators and can realize the movement of materials horizontally, vertically, and obliquely upward. When separating materials, when the materials enter the equipment, they are evenly distributed to the three axial vibrators through the feed inlet. The vibration frequency and amplitude of each axial vibrator can be adjusted according to different material characteristics and process requirements. Under the action of the three axial vibrators, the materials will be vibrated and impacted to varying degrees, so that different components in the materials are separated. The light materials will be screened out and move upward along the vibrating screen mesh, ultimately achieving the separation purpose.

[0003] During the screening process of the existing three-axis elliptical vibrating screen, larger ores are located outside the screen mesh, which will cause the small ores above the large ores to form a stack. It is difficult for the small ores above to quickly pass through the screening, resulting in a significant reduction in screening efficiency; and when the mesh of the screen is blocked, it is often necessary to remove the screen for cleaning, which is time-consuming and laborious, resulting in poor screening effects; when impurities adhere to the vibrating screen, manually spraying with a high-pressure water gun or cleaning with a brush is likely to be not thoroughly cleaned.

[0021] Refer to the following Figures 1 to 15 The embodiments of the present invention are described in detail. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0022] An intelligent three-axis elliptical vibrating screen, such as Figure 1 , Figure 3 , Figure 5 , Figure 7 , Figure 11 As shown, it includes a vibrating box 1, which is a rectangular parallelepiped structure. Two vibrating screens 2 are slidably installed up and down inside the vibrating box 1. The two vibrating screens 2 are arranged in parallel and tilted inside the vibrating box 1, and a certain distance is set between the two vibrating screens 2. The two vibrating screens 2 are in a state where the rear ends are low and the front ends are high. A plurality of rectangular sieve holes are evenly opened on the vibrating screen 2, and the inner diameter of the sieve holes of the upper vibrating screen 2 is larger than the inner diameter of the sieve holes of the lower vibrating screen 2, which facilitates the screening of ores of various specifications. Three reinforcing plates 3 are evenly fixedly installed on each of the vibrating screens 2. The reinforcing plates 3 are arranged in the front-to-back direction. The reinforcing plates 3 can provide firmness to the vibrating screen 2. Two sliding cross bars 4 are slidably installed under each of the vibrating screens 2. The sliding cross bars 4 can slide back and forth along the bottom of the vibrating screen 2, and three extension plates 5 are evenly fixedly installed on the rear end of each of the sliding cross bars 4. (It should be noted that the positional relationship of the components in this application is shown in the attached figure.) Figure 5 and attached Figure 10(for reference), each extension plate 5 is arranged corresponding to the upper reinforcement plate 3 up and down, and a certain distance is reserved between the extension plate 5 and the reinforcement plate 3. The other end of each said extension plate 5 is fixedly installed with a vertical rod 6 extending upward. Each vertical rod 6 is provided with a vertical limit hole. Each said extension plate 5 is provided with a sliding hole penetrating up and down. The sliding hole is arranged on the front side of the vertical rod 6. Inside each sliding hole, an impact rod 7 is slidably installed up and down. The top end of the impact rod 7 is fixedly installed with an impact ball. On one side surface of each impact rod 7, a positioning key is fixedly installed. The positioning key is slidably installed up and down inside the corresponding limit hole; At the bottom end of each said impact rod 7, a positioning plate located below the extension plate 5 is fixedly installed. Each positioning plate is fixedly connected with a compression spring 8. The top end of each compression spring 8 is fixedly connected to the extension plate 5. Under normal state, the impact ball is in contact with the bottom surface of the reinforcement plate 3. On the left side of each said extension plate 5, a fixed plate 9 is fixedly installed. On each said fixed plate 9, a switching gear 10 is rotatably installed, (the structure of the switching gear 10 is as Figure 15 shown). Inside the switching gear 10, a circular hole penetrating left and right is provided. On the circular wall of the circular hole, a plurality of helical teeth are uniformly fixedly connected. On the fixed plate 9, a positioning circular plate located inside the circular hole is rotatably installed. On the positioning circular plate, a positioning column is fixedly installed. On the positioning column, a top pressure spring is fixedly installed. On the positioning circular plate, a locking tooth is rotatably installed. The other end of the top pressure spring is fixedly connected to the locking tooth. The locking tooth is engaged with the helical teeth. On the positioning circular plate, a sector gear 11 located on the right side of the switching gear 10 is coaxially fixedly installed. At the front end of the impact rod 7, a vertical driving rack is fixedly installed. On the left and right top ends of each said sliding cross bar 4, vertical blocks are respectively fixedly installed. Between every two corresponding vertical blocks, a driving shaft 12 is rotatably installed. On each said driving shaft 12, three driving gears 13 are uniformly coaxially fixedly installed. Each driving gear 13 is meshed and connected with the external teeth of the corresponding switching gear 10. On each vibrating screen 2, a driving assembly is provided.

[0023] As Figure 1 、 Figure 3 shown, inside the vibrating box body 1, a conveyor belt pulley group 14 is installed. The conveyor belt pulley group 14 includes a plurality of pulley rollers and a conveyor belt. Each pulley roller is rotatably installed on the left and right inner ends below the vibrating box body 1, and the pulley roller is arranged below the lowermost vibrating screen 2. The plurality of pulley rollers are jointly connected with a conveyor belt. At the front end of the vibrating box body 1, a first outlet 15 is provided. On the left end of the vibrating box body 1, a first motor 16 is fixedly installed. The rotating shaft of the first motor 16 is coaxially fixedly connected with one of the pulley rollers. The first motor 16 is connected to a controller and a power supply. At the top end of the vibrating box body 1, a crushing assembly is provided.

[0024] As Figure 1As shown, top fixed shells 17 are fixedly installed at the front and rear ends on the left side of the vibration box body 1 respectively, and top fixed shells 17 are fixedly installed at the front and rear ends on the right side of the vibration box body 1 respectively. Three buffer springs 18 are fixedly installed at the bottom end of each top fixed shell 17. Bottom fixed shells 19 are installed at the front and rear ends on the left side of the vibration box body 1 respectively, and bottom fixed shells 19 are installed at the front and rear ends on the right side of the vibration box body 1 respectively. There is no contact between the bottom fixed shell 19 and the vibration box body 1. Each bottom fixed shell 19 and the top fixed shell 17 on the same side are arranged vertically corresponding to each other. The bottom end of each buffer spring 18 is fixedly connected to the top end of the corresponding bottom fixed shell 19. A stabilizing beam 20 is fixedly connected between the two bottom fixed shells 19 on the left side, and a stabilizing beam 20 is fixedly connected between the two bottom fixed shells 19 on the right side, so that a certain distance is reserved between the bottom end of the vibration box body 1 and the ground. First exciter groups 21, second exciter groups 22, and third exciter groups 23 are installed on the left and right ends of the vibration box body 1. A right connecting shaft is coaxially fixedly arranged between the two first exciter groups 21, a connecting shaft is coaxially fixedly arranged between the two second exciter groups 22, and a connecting shaft is coaxially fixedly arranged between the two third exciter groups 23. Each connecting shaft is rotatably installed on the vibration box body 1. The exciter group is a prior art and will not be elaborated here. And the exciter group selects the existing connection method. The exciter group is connected to the power supply, the controller, and the starting motor; Before screening the ore, the operator places the vibration box body 1 in a suitable area, turns on the power supply, and the first exciter group 21, the second exciter group 22, the third exciter group 23, and the first motor 16 work synchronously. The vibration box body 1 operates in an elliptical vibration trajectory, and the conveyor belt pulley group 14 rotates. Then the operator puts the ore blocks onto the topmost vibrating screen 2. Since the vibration box body 1 drives the vibrating screen 2 to vibrate, the piled-up ore will gradually separate. The larger ore will be blocked on the upper vibrating screen 2, and the smaller ore will pass through the upper sieve holes and fall onto the lower vibrating screen 2. The smallest ore passes through the sieve holes and falls onto the conveyor belt. The conveyor belt transports the smallest ore to the outside through the first outlet 15. Since the two vibrating screens 2 are inclined and arranged inside the vibration box body 1, and the vibration box body 1 operates in an elliptical trajectory, the screened ore can be transported backward, thus improving the screening efficiency. Due to the three-axis synchronous vibration, an elliptical movement trajectory is generated, making the ore be thrown higher and faster, significantly improving the screening efficiency; When impurities are easily adsorbed on the vibrating screen 2 during the screening process of the ore, the driving assembly is turned on, and the four sliding crossbars 4 move backward synchronously. Each drive shaft 12 drives a plurality of driving gears 13 to rotate. Each driving gear 13 meshes with the external teeth of the switching gear 10 to rotate. The helical teeth drive the positioning circular plate to rotate through the locking teeth. Each positioning circular plate drives the sector gear 11 to rotate. Each sector gear 11 meshes with the driving rack and the impact rod 7 to slide downward. Each impact rod 7 drives the compression spring 8 to stretch downward through the positioning plate. The impact ball no longer contacts the reinforcement plate 3. When the sector gear 11 disengages from the driving rack, the compression spring 8 quickly resets, and the impact rod 7 quickly slides upward. The impact ball can violently impact the reinforcement plate 3, and the impurities adsorbed on the vibrating screen 2 will be shaken off. After repeatedly impacting the reinforcement plate 3, the vibrating screen 2 is cleaned more thoroughly, and it can also prevent the impurities from corroding the vibrating screen 2; When the four sliding crossbars 4 move forward synchronously, each drive shaft 12 drives a plurality of driving gears 13 to rotate in the reverse direction. Each driving gear 13 meshes with the external teeth of the switching gear 10 to rotate in the reverse direction. The helical teeth continuously press the locking teeth to rotate. The top pressure spring will continuously compress and rebound. The sector gear 11 remains stationary. That is to say, during the forward movement of the sliding crossbar 4, the impact ball does not impact the reinforcement plate 3.

[0025] As Figure 1 、 Figure 3 As shown, the crushing assembly includes a crushing box 24. The crushing box 24 is fixedly penetrated through the front side top end of the vibrating box body 1. Two crushing rollers 25 are respectively rotatably installed between the left and right inner walls of the crushing box 24. Two driving gears 26 are rotatably installed on the left end of the crushing box 24. Each driving gear 26 is coaxially and fixedly connected to the corresponding crushing roller 25, and the two driving gears 26 are meshed and connected. A first sprocket set 27 is connected between the first motor 16 and one of the driving gears 26. The first sprocket set 27 includes two first sprockets and a first chain. A first sprocket is coaxially and fixedly installed on the rear driving gear 26. A first sprocket is coaxially and fixedly installed on the rotating shaft of the first motor 16. The two first sprockets are connected by a first chain, and the first chain is not interfered by any components during the movement process; Turn on the power supply and the controller. The first motor 16 drives the rear driving gear 26 to rotate through the first sprocket set 27. The two driving gears 26 drive their respective crushing rollers 25 to rotate. Personnel put large ore into the interior of the crushing box 24. The two crushing rollers 25 can crush the large ore during the rotation process, facilitating the subsequent screening work.

[0026] As Figure 4As shown, four cushion plates 28 are fixedly installed on the front inner wall of the vibration box body 1, and four cushion plates 28 are fixedly installed on the rear inner wall of the vibration box body 1. A vibration spring 29 is fixedly installed on the top end of each cushion plate 28. The four vibration springs 29 above are fixedly connected together at the bottom end of the upper vibration sieve 2, and the four vibration springs 29 below are fixedly connected together at the bottom end of the lower vibration sieve 2; When the ore falls onto the vibration sieve 2, the vibration springs 29 will be compressed, thus playing a buffering and protective role for the vibration sieve 2. It can also assist in vibrating and screening the ore. When the impact ball violently impacts the reinforcement plate 3, slight vibrations are generated, accelerating the cleaning effect of the vibration sieve 2.

[0027] As Figure 5 , Figure 7 , Figure 8 As shown, the driving assembly includes a second motor 30. Guide beams 31 are respectively fixedly installed on the left and right bottom ends of each vibration sieve 2. The guide beams 31 are arranged in the front-rear direction. A first rectangular hole 32 penetrates between the left and right ends of each guide beam 31. A second rectangular hole 33 communicating with the first rectangular hole 32 is opened at the bottom end of each guide beam 31. The first rectangular hole 32 and the second rectangular hole 33 are arranged in the front-rear direction. Bending rods 34 are respectively fixedly installed at both ends of each sliding cross bar 4. The other end of each bending rod 34 is slidably installed in the corresponding second rectangular hole 33. A first reciprocating lead screw 35 is rotatably installed inside the first rectangular hole 32 on the left side. A spacer rod is fixedly installed in the middle of the first reciprocating lead screw 35, thus dividing the first reciprocating lead screw 35 into two identical reciprocating lead screws. The front bending rod 34 is threadedly installed on the front first reciprocating lead screw 35, and the rear bending rod 34 is threadedly installed on the rear first reciprocating lead screw 35. A second motor 30 is fixedly installed on the front end of each guide beam 31 on the left side. The rotating shaft of the second motor 30 is fixedly connected coaxially with the corresponding first reciprocating lead screw 35. The second motor 30 is connected to the power supply and the controller; Turn on the power supply and the controller, the second motor 30 drives the corresponding first reciprocating screw rod 35 to rotate, each first reciprocating screw rod 35 drives the corresponding two curved rods 34 to slide backward synchronously, each sliding cross bar 4 moves backward synchronously, each driving shaft 12 drives multiple active gears 13 to rotate, each active gear 13 meshes with the outer teeth of the switching gear 10 to rotate, the helical teeth drive the positioning circular plate to rotate through the card teeth, each positioning circular plate drives the fan gear 11 to rotate, each fan gear 11 meshes with the driving rack and the impact rod 7 to slide downward, each impact rod 7 is stretched downward with the compression spring 8 through the positioning plate, when the fan gear 11 is disengaged from the driving rack, the compression spring 8 is quickly reset, the impact rod 7 slides upward rapidly, the impact ball impacts the reinforcement plate 3, the impurities adsorbed on the vibrating screen 2 will be shaken off, after multiple impacts on the reinforcement plate 3, the vibrating screen 2 is cleaned more thoroughly, and the impurities can also be prevented from corroding the vibrating screen 2; When each bending rod 34 moves backward to the extreme position of the first reciprocating screw rod 35, each bending rod 34 at this time will move forward along the first reciprocating screw rod 35, and each sliding cross bar 4 will move forward synchronously. Each driving shaft 12 will rotate in the opposite direction with multiple active gears 13, and each active gear 13 will rotate in the opposite direction by meshing with the outer teeth of the switching gear 10. The helical teeth will continuously press the latch teeth to rotate, the top pressure spring will continuously compress and rebound, the fan gear 11 will remain stationary, the impact ball will not impact the reinforcement plate 3, and the first reciprocating screw rod 35 can smoothly move the sliding cross bar 4 back and forth, thereby improving stability.

[0028] like Figure 9 , Figure 10 , Figure 11 , Figure 14 As shown, a positioning rack 36 is fixedly installed on the left and right bottom ends of each of the vibrating screens 2, and the positioning rack 36 is arranged on the inner side of the corresponding guide beam 31. A self-rotating shaft 37 is rotatably installed between each two curved rods 34 on the left and right sides, and the self-rotating shaft 37 is rotatably installed inside the first rectangular hole 32. A self-rotating gear 38 meshing with the corresponding positioning rack 36 is coaxially fixedly installed on each of the self-rotating shafts 37. A plurality of toggle rods 39 are evenly fixedly installed on each of the self-rotating shafts 37, and each toggle rod 39 is arranged corresponding to the sieve hole above. A third sprocket is coaxially fixedly installed on each of the self-rotating gears 38, and a third sprocket is coaxially fixedly installed on both ends of each driving shaft 12. A third chain is connected between the two second sprockets on the same side, and the installation positions of the third sprocket and the third chain are not interfered with by any components. When the ore falls into the vibrating screen 2, a part of the ore will block the screen holes, which will affect the screening effect. Turn on the power supply and the controller, and the second motor 30 drives the corresponding first reciprocating lead screw 35 to rotate. Each first reciprocating lead screw 35 drives the corresponding two bent rods 34 to slide backward synchronously. Each sliding cross bar 4 moves backward synchronously. Each self-rotating gear 38 drives the corresponding drive shaft 12 to rotate through the second sprocket set 43. At the same time, each self-rotating shaft 37 drives a plurality of shifting rods 39 to rotate. Each shifting rod 39 can push against the lower end of the ore in the screen hole during rotation, so that the ore moves downward to open the screen hole. The smaller ore passes through the screen hole and falls downward, preventing the screen hole from being blocked. When the large ore moves upward, the ore above will be squeezed and misaligned with each other, facilitating the smaller ore to fall. When the shifting rod 39 is no longer in contact with the bottom end of the ore, the ore blocks the screen hole again. In this way, the ore is lifted and dropped, and the large ore will not continuously block the screen hole, improving the screening efficiency.

[0029] As Figure 6 , Figure 8 , Figure 12 , Figure 13 shown, on the two top ends on the left side of each vibrating screen 2, symmetric convex plates 40 are respectively and fixedly installed front and back. On the two top ends on the right side of each vibrating screen 2, symmetric convex plates 40 are respectively and fixedly installed front and back. A second reciprocating lead screw 41 is rotatably installed between the corresponding two convex plates 40 on the left side. A guide rod 42 is fixedly installed on the corresponding two convex plates 40 on the right side. A second sprocket set 43 is installed between each second reciprocating lead screw 41 and the corresponding second motor 30. The second sprocket set 43 includes two second sprockets and a second chain. A second sprocket is coaxially and fixedly installed on the front end of each second reciprocating lead screw 41. A second sprocket is coaxially and fixedly connected to the rotating shaft of the second motor 30. A second chain is connected between the two second sprockets on the same side. The second chain slides up and down through the vibrating screen 2. On the left and right top ends of each vibrating screen 2, limit plates 44 are respectively and fixedly installed. A bending groove 45 is formed in each limit plate 44. (The bending groove 45 is arranged in a wavy structure, as Figure 8 shown), a sliding rod 46 is slidably installed in each bending groove 45. A reciprocating rod 47 is fixedly installed between the corresponding two sliding rods 46. One end of the reciprocating rod 47 is arranged between the second reciprocating lead screw 41 and the limit plate 44, and the other end of the reciprocating rod 47 is arranged between the guide rod 42 and the limit plate 44. Built-in holes 48 are respectively formed at both ends of each reciprocating rod 47. An inner rod 49 is slidably installed left and right in each built-in hole 48. The inner rod 49 is in a "Z" shape. The left inner rod 49 is threadedly installed on the corresponding second reciprocating lead screw 41. The front and back of the right inner rod 49 are slidably sleeved on the corresponding guide rod 42. A plurality of push rods 50 are evenly and fixedly installed on each reciprocating rod 47; Turn on the power supply and the controller. The second motor 30 drives the corresponding second reciprocating screw rod 41 to rotate through the second sprocket group 43. The corresponding built-in rod 49 moves backward synchronously with the other built-in rod 49 through the reciprocating rod 47. The reciprocating rod 47 drives the two sliding rods 46 to move along the track of the curved groove 45. At this time, the reciprocating rod 47 moves reciprocally left and right. At the same time, the built-in hole 48 will move reciprocally along the corresponding built-in rod 49. The pushing rod 50 can push the ore on the vibrating screen 2 during the reciprocating movement left and right, avoiding the aggregation of ore and affecting the falling of the smaller ore. Since the sliding rod 46 moves along the track of the curved groove 45, the pushing rod 50 can separate the stacked ore, and there will be no stacking between the ore, improving the screening efficiency.

[0030] As Figure 1 、 Figure 2 shown, two second outlets 51 are installed on the rear end of the vibrating box body 1. The discharging boxes 52 corresponding to each second outlet 51 are fixedly installed on the rear end of the vibrating box body 1. The two discharging boxes 52 are symmetrically arranged up and down. The ore conveyed from the vibrating screen 2 is discharged into a suitable device through the corresponding discharging box 52. A protective shell 53 is installed on the top end of the vibrating box body 1 by screws, which can avoid the splashing during the ore screening process and improve the safety.
