Description

Technical Field

[0001] The present invention relates to the technical field of vibrating screens, and in particular to an intelligent vibrating screen and an operating method thereof. Background Art

[0002] Due to the rapid development of science and technology, vibrating screens have also become intelligent. Intelligent vibrating screens mainly monitor three aspects: vibration (amplitude, vibration direction angle, four-corner swing, vibration frequency), temperature (temperature sensor), and monitoring of the particle size of materials screened by the vibrating screen. The information is wirelessly transmitted to the server through the sensor and calculated into visual information. Although it is intelligent, its operation mode is still similar to that of traditional vibrating screens.

[0003] There are many types of vibrating screens, such as mining vibrating screens. Nowadays, most vibrating screens have too simple structures. The screen plates are generally fixed to the body by bolts and connectors. The screen aperture is fixed and cannot screen mineral materials of different calibers. In order to adapt to the particle size of the materials to be produced, it is often necessary to manually replace the screens with different apertures. The workload is greatly increased during the disassembly and assembly of the screen plates.

[0014] An operation method of an intelligent vibrating screen comprises the following steps:

[0015] a. Transmission mode of the first screw and adjustment of the diameter of the wire

[0016] One of the first screws is driven to rotate by the second motor, and the four first screws are driven by bevel gear meshing. The four first screws rotate synchronously and drive the threads of the first sliders to rotate. Since the two ends of the wire body are fixedly connected to the corresponding first sliders and the wire body is made of rigid material, the first slider slides linearly on the first screw, and the α rod and β rod of the first screw decrease in double increments along the thread diameter away from one end. The threads of the two ends centered on the first partition block face opposite directions, so that the first sliders on both sides of the first partition block slide toward or away from each other, thereby adjusting the spacing between two adjacent wire bodies.

[0017] b. The first screw drives the second screw to rotate and the distance between the shield and the second screw is adjusted

[0018] The first screw drives the second screw to rotate through the meshing of the first spur gear and the second spur gear, and the rotation of the second screw drives a pair of second sliders to move. Since the anti-rotation block at the top of the second slider is limited by the corresponding anti-rotation groove, the second slider slides linearly on the second screw. The threads at both ends of the second screw with the second partition block as the center are in opposite directions, causing the two second sliders to slide towards each other or slide in the opposite directions. The shield plate is pushed by adjusting the angles of the two push rods to adjust the distance between the shield plate and the second screw.

[0019] c. Angle adjustment of the mounting bracket and the blanking support plate

[0020] The third motor drives the driving gear to rotate and drives the unloading support plate to rotate. The unloading support plate drives the mounting bracket to rotate synchronously through the first support rod and the second support rod. The driving gear drives the driven gear to rotate synchronously through the toothed belt, thereby driving the third support rod to rotate. The transmission between the two third support rods is supported by the fourth support rod, so that the angles of the mounting bracket and the unloading support plate are adjusted synchronously.

[0021] d. The feeding box feeds the screen frame and the feeding box recovers the waste from the lower support plate

[0022] The loading hopper puts the material into the loading chamber, and utilizes the inclined surface at the bottom end of the loading chamber and the inclined surface at the top end of the loading bracket plate to convey the material to the screen composed of a plurality of wire bodies. A pair of the telescopic rods telescopically push the loading bracket plate to adjust the angle between the loading bracket plate and the loading box, so as to adapt to the height of one end of the screen frame. A pair of the vibrators drive the mounting bracket and the screen frame to vibrate, so that the screen screens the material. The waste stuck on the screen falls onto the unloading support plate by adjusting the diameter of the wire body. The angle of the unloading support plate is adjusted so that one end of the unloading support plate is aligned with the recovery support plate, and the waste is recovered into the feeding chamber, and the first motor is driven to drive the screw conveying paddle to rotate, and the waste is lifted and transported from bottom to top to the loading chamber through the feeding chamber. In the process of conveying the waste, a plurality of irregular protrusions on the inner wall of the feeding chamber and the outer wall of the screw conveying paddle grind the waste, and then the grinded waste is conveyed to the screen again through the loading bracket plate for screening.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] The present invention drives one of the first screws through a second motor, and the four first screws are driven by bevel gear meshing, so that the four first screws rotate synchronously, and the rotation of the first screw drives a plurality of first sliders to slide. Since the α rod and the β rod of the first screw decrease in double increments along two screw diameters away from one end from each other, and the threads of the α rod and the β rod are opposite, the plurality of first sliders on the α rod and the β rod slide toward each other or oppositely, and the spacing between two adjacent wire bodies is adjusted. Different sizes of mineral materials can be adapted according to the adjusted screen aperture, and there is no need to disassemble and assemble the adapted screen plate, thereby reducing the workload.

[0025] The present invention adjusts several wire bodies to expand the caliber so that the waste stuck on the screen falls onto the unloading support plate, and drives the unloading support plate to rotate by driving the active gear through the third motor, adjusts one end of the unloading support plate to align with the recovery bracket plate to discharge the waste into the feeding cavity, and lifts the waste from bottom to top through the feeding cavity to the loading cavity, and grinds the waste with several irregular protrusions on the inner wall of the feeding cavity and the outer wall of the spiral conveying paddle, and then transports it to the screen for screening again through the loading bracket plate, which effectively performs secondary screening of the waste, saves costs, and facilitates cleaning of the screen.

DETAILED DESCRIPTION

[0037] 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.

[0038] See also Figure 1-10The present invention provides a technical solution: an intelligent vibrating screen, comprising a feeding box 1, both sides of the feeding box 1 are fixedly connected with side support plates 2, a feeding support plate 3 is movably installed between the inner sides of the two side support plates 2, the opposite sides of the two side support plates 2 are rotatably connected with mounting brackets 4, a screen frame 5 is installed between the two mounting brackets 4, a device box 6 and an exciter 8 are symmetrically installed on the side of the two side support plates 2 away from each other, and the exciter 8 is located above the device box 6, and four first screws 51 are installed on the inner side of the screen frame 5 in a rectangular shape. The frame is provided with four first screw rods 51 of different lengths. The middle of each first screw rod 51 is fixedly connected with a first partition block 511. A plurality of first sliders 513 are threadedly sleeved on each of the four first screw rods 51. A spacer 512 is provided between two adjacent first sliders 513. The plurality of spacers 512 are distributed in an array and fixedly connected to the first screw rod 51. A pair of mutually symmetrical first sliders 513 are fixedly connected with a wire body 514. Both ends of the first screw rod 51 are fixedly sleeved with a bevel gear 515. , the two slightly longer first screw rods 51 are symmetrically fixedly connected with the first spur gear 516, and the first spur gear 516 is located on one side of the bevel gear 515, and the second screw rod 52 is arranged above the two slightly longer first screw rods 51, and the second partition block 521 is fixedly connected to the middle of the second screw rod 52, and the second screw rod 52 is threadedly sleeved with symmetrically distributed second sliders 522, and the two second sliders 522 are rotatably connected with push rods 523, and a shielding plate 53 is installed between the ends of the two push rods 523 away from the second sliders 522, and a stop block 524 is fixedly connected to the top of the second slider 522, and the second spur gear 525 is fixedly sleeved at both ends of the second screw rod 52. In the scheme of the present invention, the exciter 8 is built-in with a vibration sensor and a temperature sensor, and a plurality of particle size sensors are installed in the inner array of the screen frame 5 near the bottom end of the first screw 51, and the vibration sensor, temperature sensor and particle size sensor are all connected to the server computing signal, and the wireless transmission to the server is calculated to become visualized information, which is not elaborated in detail for the prior art.

[0039] Furthermore, the first screw 51 and the second screw 52 are respectively provided with an α rod and a β rod with the first partition block 511 and the second partition block 521 as the center, and the threads of the α rod and the β rod are opposite. The α rod and the β rod of the first screw 51 decrease in double increments along the thread diameter away from one end from each other. The line body 514 between the two longer first screws 51 and the line body 514 between the two shorter first screws 51 are arranged alternately. When the first screw 51 rotates, the first slider 513 and the second slider 522 can only slide toward or in opposite directions, thereby limiting the distance synchronization when each first slider 513 slides.

[0040] Furthermore, one end of the four first screw rods 51 respectively extends into the interior of the screen body frame 5, and each first screw rod 51 is rotatably connected to the screen body frame 5, both ends of the second screw rod 52 extend into the interior of the screen body frame 5, and each second screw rod 52 is rotatably connected to the screen body frame 5, the adjacent ends of the two longer first screw rods 51 and the two shorter first screw rods 51 are meshed and connected through a bevel gear 515, and the two ends of the adjacent first screw rods 51 and the second screw rods 52 are meshed and connected through a first spur gear 516 and a second spur gear 525, and the bottom end of the shield plate 53 contacts the wire body 514, and the transmission through the bevel gear 515 facilitates the synchronous rotation of the four first screw rods 51, and the adjacent two first screw rods 51 and the second screw rod 5 The first spur gear 516 and the second spur gear 525 are meshed and connected. The transmission of the first spur gear 516 and the second spur gear 525 facilitates the first screw 51 to synchronously drive the second screw 52 to rotate. The bottom end of the shielding plate 53 contacts the wire body 514. When the first slider 513 is adjusted to drive the diameter of the two adjacent wire bodies 514 to decrease, the four sides of the screen mesh shrink inward, and the gap between the four sides of the screen mesh and the screen body frame 5 becomes larger. At the same time, the second screw 52 rotates, and the two second sliders 522 thereon rotate toward each other. By adjusting the angle between the pair of push rods 523 and the second screw 52, ​​the shielding plate 53 is pushed to cover the existing gap, effectively preventing the screen mesh from falling out of the side gap when screening mineral materials.

[0041] Furthermore, a plurality of slots 41 are provided in an array on the inner bottom wall of the mounting bracket 4, and anti-rotation slots 54 are provided on both sides of the inner top wall of the screen frame 5. The second slider 522 is limited to slide in the corresponding anti-rotation slots 54 by the anti-rotation blocks 524. A plurality of built-in slots 55 are provided in an array on both sides of the bottom end of the screen frame 5, and blocks 56 are fixedly installed in the built-in slots 55 by springs. The screen frame 5 is engaged with the corresponding slots 41 through the cooperation of the plurality of blocks 56 and the corresponding slots 41 and is clamped on the mounting bracket 4. A second motor 57 is fixedly installed on the outer side wall of the screen frame 5, and one end of one of the relatively long first screws 51 is fixedly connected to the output shaft of the second motor 57. By inserting the screen frame 5 from one end of the two mounting brackets 4, the block 56 is designed in a triangular shape, and the inclined surface of its shape can reduce resistance during insertion. When the screen frame 5 as a whole overlaps with the two mounting brackets 4, its plurality of blocks 56 are clamped in the corresponding slots 41 to achieve limited clamping, thereby achieving rapid installation of the screen frame 5 and the mounting bracket 4.

[0042] Furthermore, the bottom ends of the two mounting brackets 4 are movably mounted with a first support rod 7 and a second support rod 71, and the bottom end of the first support rod 7 is movably mounted at a corresponding position on the top of the blanking support plate 3, and the bottom end of the second support rod 71 passes through a through hole corresponding to the blanking support plate 3 and is movably connected thereto, and a third support rod 73 is movably mounted on the bottom end of the second support rod 71, and a fourth support rod 74 is fixedly connected between the two third support rods 73, a third motor 61 is fixedly mounted on one side of one device box 6 away from the side support plate 2, a driving gear 75 and a driven gear 76 are rotatably mounted in the two device boxes 6, and the driven gear 76 is located below the driving gear 75, and the output end of the third motor 61 passes through one side of the device box 6 and the side support plate 2 and is respectively connected to the driving gear 75 and the lower One side of the material support plate 3 is fixedly connected, and a toothed belt 77 is meshed between the driving gear 75 and the driven gear 76. One end of the driven gear 76 is fixedly connected to the end of the third support rod 73 away from the fourth support rod 74. The material discharge support plate 3 and the mounting bracket 4 are transmitted through the first support rod 7, the side support plate 2, the third support rod 73 and the fourth support rod 74. The driving gear 75 and the driven gear 76 are transmitted through the toothed belt 77. The third motor 61 drives the driving gear 75 to synchronously adjust the angles of the mounting bracket 4 and the material discharge support plate 3. The suitable inclined surface can be adjusted according to the different weights of minerals. When the mineral material rolls on the screen and the material discharge support plate 3, it is necessary to avoid excessive or small slopes, which may cause excessive or small inertia and affect incomplete screening and material jamming.

[0043] Furthermore, a loading hopper 11 is fixedly connected to the top of the loading box 1, a loading chamber 12 is provided at the top of the inner cavity of the loading box 1, and the bottom end of the loading chamber 12 is inclined, a feeding chamber 13 is provided in the middle of the inner cavity of the loading box 1, a first motor 14 is fixedly installed at the bottom of the inner cavity of the loading box 1, a screw conveying paddle 15 is installed in the feeding chamber 13, and the screw conveying paddle 15 is in contact with the cavity wall of the feeding chamber 13, and a plurality of irregular protrusions are provided on the inner wall of the feeding chamber 13 and the outer wall of the screw conveying paddle 15, a loading bracket plate 16 is movably installed on one side of the loading box 1 through a plurality of hinges, and the loading bracket plate 16 is located above one end of the screen frame 5, a recovery bracket plate 17 is fixedly connected to one side of the loading box 1, and the recovery bracket plate 17 is located below one end of the lower material support plate 3, and one end of the screw conveying paddle 15 It is fixedly connected to the output end of the first motor 14 through a movable shaft, and the other end of the screw conveying paddle 15 passes through the loading chamber 12 and is flush with the bottom end of the loading chamber 12. The recovery bracket plate 17 is tilted and connected to the feeding chamber 13. A pair of telescopic rods 161 are movably installed between the bottom end of the loading bracket plate 16 and the side wall of the loading box 1, and the telescopic rods 161 are tilted. By driving the pair of telescopic rods 161 to telescopically adjust the inclined surface of the loading bracket plate 16 and the loading chamber 12, it is convenient to load the screen frame 5 with different inclinations. The screw conveying paddle 15 is driven to rotate by the first motor 14, and the waste on the unloading support plate 3 can be transported into the feeding chamber 13 through the recovery bracket plate 17, and then transported to the loading chamber 12, and the loading bracket plate 16 is used to perform secondary loading on the screen.

[0044] Furthermore, the rotating shafts of the two mounting brackets 4 rotatably connected to the side support plates 2 are respectively fixedly connected to the corresponding output ends of the vibrator 8, the unloading support plate 3 and the mounting bracket 4 have the same inclination angle, and the top of the unloading support plate 3 is V-shaped, which is convenient for collecting the mineral materials falling from the screen from both sides to the middle, which is beneficial to the transportation of the screened materials and the discharge of waste materials to the recovery bracket plate 17.

[0045] An operation method of an intelligent vibrating screen comprises the following steps:

[0046] a. Transmission mode of the first screw 51 and diameter adjustment of the wire 514

[0047] One of the first screw rods 51 is driven to rotate by the second motor 57, and the four first screw rods 51 are meshed and driven by the bevel gear 515. The four first screw rods 51 rotate synchronously and drive the first sliders 513 to rotate in a threaded manner. Since the two ends of the wire body 514 are fixedly connected to the corresponding first sliders 513, and the wire body 514 is made of rigid material, the first slider 513 slides linearly on the first screw rod 51, and the α rod and the β rod of the first screw rod 51 decrease in double increments along the thread diameter away from one end. The threads at the two ends centered on the first partition block 511 face opposite directions, causing the first sliders 513 on both sides of the first partition block 511 to slide toward or away from each other, thereby adjusting the spacing between two adjacent wire bodies 514;

[0048] b. The first screw 51 drives the second screw 52 to rotate and the distance between the shield 53 and the second screw 52 is adjusted

[0049] The first screw 51 is meshed with the second spur gear 525 through the first spur gear 516 to drive the second screw 52 to rotate. The rotation of the second screw 52 drives a pair of second sliders 522 to move. Since the anti-rotation block 524 at the top of the second slider 522 is limited by the corresponding anti-rotation groove 54, the second slider 522 slides linearly on the second screw 52. The threads at both ends of the second screw 52 with the second partition block 521 as the center face opposite directions, causing the two second sliders 522 to slide towards each other or oppositely. The shield plate 53 is pushed by adjusting the angles of the two push rods 523, so as to adjust the distance between the shield plate 53 and the second screw 52.

[0050] c. Angle adjustment of mounting bracket 4 and blanking support plate 3

[0051] The third motor 61 drives the driving gear 75 to rotate and drive the unloading support plate 3 to rotate. The unloading support plate 3 drives the mounting bracket 4 to rotate synchronously through the first support rod 7 and the second support rod 71. The driving gear 75 drives the driven gear 76 to rotate synchronously through the toothed belt 77, thereby driving the third support rod 73 to rotate. The transmission is supported by the fourth support rod 74 between the two third support rods 73, so that the angles of the mounting bracket 4 and the unloading support plate 3 are adjusted synchronously.

[0052] d. Feeding box 1 feeds the screen frame 5 and feeding box 1 feeds the unloading support plate 3 to recycle waste

[0053] The loading hopper 11 puts the material into the loading chamber 12, and uses the inclined surface at the bottom end of the loading chamber 12 and the inclined surface at the top end of the loading bracket plate 16 to transport the material to the screen composed of a plurality of wire bodies 514. A pair of telescopic rods 161 telescopically push the loading bracket plate 16 to adjust the angle between the loading bracket plate 16 and the loading box 1 to adapt to the height of one end of the screen frame 5. A pair of vibrators 8 drives the mounting bracket 4 and the screen frame 5 to vibrate so that the screen screens the material. The waste stuck on the screen falls to the screen through the diameter change of the adjusting wire body 514. On the unloading support plate 3, adjust the angle of the unloading support plate 3 so that one end of the unloading support plate 3 is aligned with the recovery bracket plate 17, and recycle the waste into the feeding chamber 13, drive the first motor 14 to drive the screw conveying paddle 15 to rotate, and the waste is lifted and transported from bottom to top to the loading chamber 12 through the feeding chamber 13. In the process of conveying the waste, several irregular protrusions on the inner wall of the feeding chamber 13 and the outer wall of the screw conveying paddle 15 grind the waste, and then the grinded waste is transported to the screen again through the loading bracket plate 16 for screening.
