Description

Technical Field

[0001] This application relates to the field of ore sorting equipment technology, and in particular to an ore vibration sorting device. Background Technology

[0002] Ore vibration sorting equipment is an industrial equipment that uses the principle of mechanical vibration and the differences in the physical properties of materials to achieve efficient ore classification. Its core function is to use vibration to make materials of different particle sizes or densities stratify, pass through the screen or be discharged in a directional manner on the screen surface, thereby completing the separation process.

[0003] The patent document with publication number CN117299558A discloses a multi-stage sorting device for molybdenum ore, in which the ore slides down through a vibrating screen plate, gradually separating ore of different particle sizes. This has certain positive significance, but it also has certain drawbacks. For example, the ore on the screen plate rolls and slides down, and some ore that could originally fall through a specific screen plate will pass through the screen holes in the screen plate during the rolling process, resulting in screening failure and affecting the final screening effect. Utility Model Content

[0004] The purpose of this application is to provide an ore vibration sorting device to solve the above-mentioned problems.

[0005] To achieve the above objectives, the technical solution of this application is as follows: A vibratory ore sorting device includes three vibratory screening units connected in a descending order of height. Each vibratory screening unit includes a support frame, on which a vibratory screen plate is movably mounted. A turbulence wheel is rotatably mounted on the vibratory screen plate, and the turbulence wheel includes multiple circumferentially spaced turbulence rods. The screen holes in the vibratory screen plates of the three vibratory screening units gradually increase in size from high to low.

[0006] Preferably, the vibrating screen plate is provided with a rotating hole, and the turbulence wheel further includes a rotating shaft, which is rotatably disposed in the rotating hole, and a plurality of turbulence rods are disposed on the outer wall of the rotating shaft.

[0007] Preferably, the side wall of the vibrating screen plate is provided with a hinge shaft, a baffle is rotatably provided on the hinge shaft, and a torsion spring is also provided on the hinge shaft to prevent the baffle from rotating along the material flow direction.

[0008] Preferably, the bracket is provided with a rotating roller, and a plurality of rotating cams are sleeved on the rotating roller and spaced apart along the axial direction of the rotating roller. The rotating cams are provided with locking holes radially, and set screws are screwed into the locking holes. The set screws are used to lock the rotating cams to the rotating roller.

[0009] Preferably, the top of the bracket is provided with a slot, the slot is inclined to correspond to the vibrating screen plate, and the two sides of the vibrating screen plate are respectively arranged in the slot; a limiting plate is provided at the relatively lower end of the slot to prevent the vibrating screen plate from slipping off.

[0010] Preferably, the sidewall of the slot is provided with an upper support, the top of the bracket is provided with a lower support, and a first spring connects the upper support and the lower support.

[0011] Preferably, the bracket is equipped with a motor, the end of the rotating roller is equipped with a counterweight wheel, and the end of the rotating roller is connected to the end of the motor via a pulley and a belt.

[0012] Preferably, the bracket is provided with an adjustment seat, one end of which is hinged to the bracket and the other end is provided with a first mounting hole. The bracket is provided with a second mounting hole corresponding to the first mounting hole. A T-shaped rod is inserted through the first mounting hole.

[0017] The present application will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present application, and therefore only show the components relevant to the present application.

[0018] like Figure 1-9 As shown, an ore vibration sorting device includes three vibration screening units 1 connected in a series of inclined sections from high to low. Each vibration screening unit 1 includes a support 111, on which a vibration screen plate 10 is movably mounted. A turbulence wheel is rotatably mounted on the vibration screen plate 10, and the turbulence wheel includes multiple circumferentially spaced turbulence rods 50. Along the order from high to low, the screen holes in the vibration screen plates 10 of the three vibration screening units 1 gradually increase in size.

[0019] The three vibrating screening units 1 are connected at an incline from high to low to form a continuous sorting channel, which facilitates the gradual flow of ore under the action of gravity and vibration.

[0020] Each vibrating screening unit 1 includes a support frame 111, which provides support for the entire unit and can be made of welded steel to ensure structural strength.

[0021] The vibrating screen plate 10, which is movably mounted on the support 111, is the core component for sorting. Its inclination angle is generally between 15° and 30°, which ensures that the ore can flow naturally while allowing enough time to complete the screening.

[0022] The turbulence wheel rotatably mounted on the vibrating screen plate 10 has multiple circumferentially spaced turbulence rods 50 that can rotate. When the ore flows on the screen plate, the turbulence rods 50 will disturb the ore, break the regular rolling trajectory of the ore, and prevent it from directly passing through the screen holes due to inertia.

[0023] The screen openings of the three vibrating screen plates 10 gradually increase in size from high to low, allowing smaller particles of ore to pass through the high-level screen plate first, medium-sized particles through the middle screen plate, and the largest particles to be discharged from the low-level screen plate, thus achieving multi-stage separation. Compared to the problem of ore easily passing through the screen openings in the prior art, this structure increases the contact opportunity between the ore and the screen openings through the disturbance of the turbulence wheel, significantly reducing the screening failure rate and improving the separation accuracy.

[0024] In some further embodiments, the vibrating screen plate 10 is provided with a rotating hole, and the turbulence wheel also includes a rotating shaft 51, which is rotatably disposed in the rotating hole, and a plurality of turbulence rods 50 are disposed on the outer wall of the rotating shaft 51.

[0025] The rotating hole on the vibrating screen plate 10 provides an installation position for the turbulence wheel. The rotating shaft 51 of the turbulence wheel is rotatably set in the rotating hole to ensure smooth rotation of the rotating shaft 51 and reduce friction loss.

[0026] Multiple baffles 50 are evenly distributed on the outer wall of the rotating shaft 51, which can effectively disturb the ore without excessively hindering the ore flow. This allows the baffle wheel to disturb the ore with simple rotation, making installation and maintenance convenient. Furthermore, the spacing of the baffles 50 can be designed according to the ore particle size to further optimize the disturbance effect.

[0027] In some further embodiments, the side wall of the vibrating screen plate 10 is provided with a hinge shaft, a baffle 4 is rotatably provided on the hinge shaft, and a torsion spring 40 is also provided on the hinge shaft to prevent the baffle 4 from rotating along the material flow direction.

[0028] The side wall of the vibrating screen plate 10 is fixed with a hinge shaft, and the baffle plate 4 is rotatably sleeved on the hinge shaft through the shaft hole, and can rotate freely around the hinge shaft.

[0029] One end of the torsion spring 40, fitted on the hinge shaft, is connected to the side wall of the screen plate, and the other end is connected to the baffle plate 4. Its elastic force prevents the baffle plate 4 from rotating along the material flow direction. When the ore flows downward along the screen plate and impacts the baffle plate 4, the baffle plate 4 will overcome the elastic force of the torsion spring 40 and rotate downstream to make way for the ore. After the ore passes through, the torsion spring 40 drives the baffle plate 4 to reset, which again blocks and diverts the subsequent ore, thereby further disrupting the flow rhythm of the ore and preventing the ore from agglomerating to form a "material flow bundle" and passing through the screen holes. At the same time, the elastic effect of the torsion spring 40 can adapt to the impact of ores of different sizes, enhancing the adaptability of the device.

[0030] In some further embodiments, a rotating roller 7 is provided on the bracket 111, and a plurality of rotating cams 70 are sleeved on the rotating roller 7 and spaced apart along the axial direction of the rotating roller 7. A locking hole 71 is provided radially on the rotating cam 70, and a set screw is screwed into the locking hole 71. The set screw is used to lock the rotating cam 70 and the rotating roller 7.

[0031] The rotating roller 7, mounted on the support 111 and corresponding to the bearings, can rotate freely. Several rotating cams 70, fitted onto the rotating roller 7, are arranged axially at intervals. The protruding parts of the cams periodically push up the vibrating screen plate 10 during rotation, driving the screen plate to vibrate. Locking holes 71 on the rotating cams 70 radially penetrate the roller body. After the set screw is screwed into the locking hole 71, it can press against the outer wall of the rotating roller 7, fixing the cam in the desired position. By adjusting the axial position and circumferential angle of different cams on the rotating roller 7, the vibration amplitude and frequency of different parts of the screen plate can be changed to adapt to the screening needs of different areas of the screen plate. For example, a larger vibration amplitude can be set at the feed end to disperse the ore, while a smaller amplitude can be set at the discharge end to ensure sufficient screening, thus improving the flexibility of the device.

[0032] In some further embodiments, the top of the support 111 is provided with a slot, the slot is inclined to correspond to the vibrating screen plate 10, and the two sides of the vibrating screen plate 10 are respectively provided in the slot; a limiting plate 100 for preventing the vibrating screen plate 10 from slipping is provided at the relatively lower end of the slot.

[0033] The slot at the top of the bracket 111 is aligned with the inclination direction of the vibrating screen plate 10. The two sides of the vibrating screen plate 10 are correspondingly embedded in the slot. The slot can provide a certain constraint on the vibration of the vibrating screen plate 10, thus preventing the vibration of the vibrating screen plate 10 from becoming uncontrollable.

[0034] The limiting plate 100, which is set at the relatively lower end of the slit, is higher than the side of the screen plate. It can block the screen plate when the vibration amplitude is large, preventing it from slipping out of the slit. This not only ensures the freedom of the screen plate to vibrate, but also provides safety protection through the limiting plate 100, thereby improving the stability of the device operation.

[0035] In some further embodiments, the sidewall of the slot is provided with an upper support 20, the top of the bracket 111 is provided with a lower support 21, and a first spring 22 is connected between the upper support 20 and the lower support 21.

[0036] An upper support 20 is welded to the side wall of the slit, and a lower support 21 is welded to the top of the support 111. The first spring 22 connecting the upper support 20 and the lower support 21 can be a helical spring. The first spring 22 is used to reduce the vibration of the vibrating screen plate 10 on the support 111 during sliding, thereby extending the service life of the equipment.

[0037] In some further embodiments, the bracket 111 is provided with a motor 6, and the end of the rotating roller 7 is provided with a counterweight wheel 62. The end of the rotating roller 7 is connected to the end of the motor 6 through a pulley 61 and a belt 60.

[0038] The motor 6 fixed on the bracket 111 provides power for the vibration.

[0039] The counterweight wheel 62 installed at the end of the rotating roller 7 can balance the centrifugal force during rotation, reducing noise and wear caused by equipment vibration. The end of the rotating roller 7 and the output shaft of the motor 6 are respectively equipped with pulleys 61, which are connected by a belt 60 to realize power transmission. The belt drive has the characteristics of buffering and absorbing vibration, which can make the rotating roller 7 rotate more smoothly, avoid the rigid impact caused by direct drive of the motor 6, and ensure the stability of vibration.

[0040] In some further embodiments, the bracket 111 is provided with an adjustment seat 8, one end of which is hinged to the bracket 111, and the other end is provided with a first mounting hole. The bracket 111 is provided with a second mounting hole corresponding to the first mounting hole. A T-shaped rod 80 is inserted through the first mounting hole. The vertical end of the T-shaped rod 80 passes through the first mounting hole and the second mounting hole in sequence, and an adjustment nut 82 is screwed onto the end that extends out of the second mounting hole. A second spring 81 is sleeved on the T-shaped rod 80, and the second spring 81 is located between the first mounting hole and the second mounting hole.

[0041] One end of the adjustment seat 8 on the bracket 111 is hinged to the bracket 111 via a hinge rod, and the first mounting hole at the other end corresponds to the second mounting hole on the bracket 111.

[0042] The vertical end of the T-shaped rod 80 passes through the first mounting hole and the second mounting hole in sequence. The adjusting nut 82 screwed onto the end that protrudes from the second mounting hole can adjust the position of the T-shaped rod 80, thereby changing the compression of the second spring 81 (located between the first and second mounting holes) sleeved on the T-shaped rod 80. By rotating the adjusting nut 82, the tension of the second spring 81 on the adjusting seat 8 can be changed, thereby adjusting the mounting angle of the motor 6 and the rotating roller 7, thus achieving tensioning of the belt 60.

[0043] In some further embodiments, each vibrating screening unit 1 is provided with a feed pipe 11, which is located below the vibrating screen plate 10; a feed inlet is provided upstream of the higher vibrating screen plate 10.

[0044] The feed pipe 11 in any vibrating screening unit 1 is located below the vibrating screen plate 10. Its upper end opening corresponds to the screen hole area of ​​the screen plate, and its lower end can be connected to a collection device to receive the ore that passes through the screen hole.

[0045] The feed inlet, located upstream of a relatively high vibrating screen plate 10, can be connected to an ore conveying device via a chute to uniformly feed the ore to be sorted into the device. This allows ores of different particle sizes to pass through their respective screen plates and be collected through a dedicated feed pipe 11, avoiding material mixing. At the same time, the feed inlet ensures that the ore enters evenly, laying the foundation for subsequent sorting and improving the overall sorting efficiency.

[0046] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this application.
