Description

Technical Field

[0001] This invention relates to screening equipment technology, specifically to an intelligent vibrating screen for mineral screening. Background Technology

[0002] A vibrating screen is a mechanical device that uses vibration to classify and screen materials. It is widely used in industries such as mining, metallurgy, coal, building materials, chemicals, and food, and is one of the core pieces of equipment in material handling processes. Its core principle is to utilize the reciprocating vibration generated by a vibrating motor or exciter. This vibration causes the material to move in a parabolic trajectory on the screen surface, increasing the probability of contact with the screen openings. Fine particles pass through the openings and fall, while coarse particles are trapped on the screen surface, forming stratification. The vibration direction is matched with the screen surface inclination angle, propelling the material along the screen surface to achieve continuous screening and thus separation by particle size.

[0003] In existing intelligent vibrating screens for mineral screening, after the initial screening of the ore, multiple more detailed secondary screenings are required. During the secondary screening, it is necessary to completely separate minerals of different sizes as they pass through the vibrating screen. Therefore, it is necessary to reduce the residence time of the ore within the vibrating screen. However, ores with a near-round shape will pass through the screen quickly during screening, resulting in incomplete screening. Current technicians usually adjust the tilt angle of the screen to reduce the inclination angle and slow down the movement speed of the ore within the vibrating screen. However, the vibrating screen is relatively large, and adjusting the tilt angle is difficult and inconvenient. Another method is to block the ore to keep it on the screen, but there is a possibility that the ore will get stuck between the screen and the blocking object, resulting in a decrease in the screening efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide an intelligent vibrating screen for mineral screening, so as to overcome the above-mentioned shortcomings in the prior art.

[0006] Furthermore, the barrier plate unit includes an inclined plate arranged at an angle, the power unit includes a power component, one side of the support rod is fixedly connected to the power component, and the power component is used to drive the inclined plate to rotate around its own output shaft axis, thereby adjusting the inclination angle of the inclined plate.

[0007] Furthermore, the support rod is installed on the outside of the screen body, and the bottom of the support rod is fixedly connected to the ground;

[0008] The top plate is fixedly installed on the top of the support rod, and the top plate is located above the screen body.

[0032] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0033] Example 1:

[0034] Please see Figure 1 and Figures 3 to 7A smart vibrating screen for mineral screening includes a screen body 1, which is inclined. The screen body 1 has a screen mesh 2 at its inner bottom. Several clips 3 are fixedly installed on the inner side of the screen body 1, and the screen mesh 2 is fixedly installed on the inner side of the screen body 1 via the clips. An adjustment unit 5 is provided on one side of the screen body 1. The adjustment unit 5 includes a support rod 52, a support rod 52 mounted on top of the support rod 52, a power unit mounted on the support rod 52, and a baffle plate unit. The power unit adjusts the position of the baffle plate unit, which is used to block part of the ore at the top of the screen mesh 2, slowing down the movement speed of the ore at the top of the screen mesh 2.

[0035] The inclined screen body 1 utilizes gravity to assist the ore in sliding down, while the vibrating motor of the screen body 1 generates high-frequency vibration, causing the ore to jump forward on the screen mesh 2, thereby achieving particle stratification and screening.

[0036] Screen 2 is quickly fixed by clips 3, facilitating the replacement of screens 2 with different aperture sizes. Under vibration, fine particles of ore pass through screen 2 and fall, while larger particles move along the inclined screen surface to the end for discharge. The screen holes of screen 2 have a conical structure, smaller at the top and larger at the bottom, making it less prone to clogging during operation and ensuring high screening efficiency. Screen 2 is a polyurethane-edged perforated screen plate, which has excellent wear resistance, high opening rate, and a service life 2-4 times that of stainless steel screens. Polyurethane screens are lightweight, reducing the weight load on the screen surface, saving power consumption, and extending the service life of the screening machine. They also have good corrosion resistance and moisture resistance, and can be used for extended periods at a pH of 7. Operating in an alkaline medium of -12°C, the screen does not generate static electricity during ore screening due to friction, resulting in strong noise reduction and minimizing noise pollution in the working environment. It is easy to assemble and disassemble. Screen 2 is a polyurethane-framed stainless steel slotted screen plate, with a service life 1-3 times that of metal wire mesh screens. The polyurethane-framed stainless steel slotted screen plate possesses elasticity and force. When some ore is stuck in the screen holes of screen 2, the elasticity of the polyurethane-framed stainless steel slotted screen plate during operation forces the stuck material through the screen holes, becoming oversize or undersize product. Furthermore, the secondary high-frequency vibration during screening prevents fine particles from adhering, reducing clogging. It improves screening efficiency, effectively absorbs impact, reduces noise, and improves the working environment of screening. It is also lightweight, flexible, and easily replaced via lateral tensioning using snap-fit ​​3. Furthermore, it is convenient for transportation and storage. It features high open area and reduced vibration noise, and its dewatering performance is superior to traditional polyurethane screens. The screen mesh 2 is a discontinuous polyurethane screen with excellent wear resistance, resulting in a lifespan 2-4 times longer than stainless steel screens. Its lightweight design reduces the weight load during screening, saves energy, and extends the service life of the screening device. It also has good corrosion resistance and moisture resistance, allowing it to operate for extended periods at various pH levels. It operates in alkaline media with a value of 7-12, has strong noise reduction capabilities, reduces noise pollution in the working environment, and is easy to assemble and disassemble. Screen 2 is a high-resilience polyurethane screen plate (MDi system), which is used for screening sand and gravel aggregates (0.2-50MM). It has many advantages such as excellent wear resistance, high-resilience jumping screening, light weight, convenient installation, and reduced power consumption. It has outstanding screening advantages. Screen 2 is a V-shaped polyurethane screen plate, which increases the opening rate by 92% compared with flat polyurethane screen plates. Its screen gap is 0.1-8mm. Screen 2 is a high-frequency dewatering screen plate used for screening coal, iron powder, tailings, silt, etc.

[0037] Support rod 52 is installed on the outside of screen body 1, and the bottom of support rod 52 is fixedly connected to the ground;

[0038] The top plate 51 is fixedly installed on the top of the support rod 52, and the top plate 51 is located above the screen body 1.

[0039] The power unit includes:

[0040] Translation drive component 59 is rotatably mounted on the bottom of top plate 51;

[0041] The drive source 53 is fixedly installed on one side of the top plate 51;

[0042] The threaded rod 54 is fixedly mounted to the output end of the drive source 53 via a coupling.

[0043] The barrier plate unit includes:

[0044] A baffle plate 56 is rotatably mounted on one end of a translation drive component 59, and the baffle plate 56 is tilted.

[0045] An adjusting ball 55 is rotatably mounted on one side of a baffle plate 56. The adjusting ball 55 is penetrated by a threaded rod 54, and the outer side of the threaded rod 54 is threadedly connected to the penetration point of the adjusting ball 55.

[0046] Adjustment plate 57 is rotatably mounted on the bottom of baffle plate 56;

[0047] A limiting plate 58 is disposed at the bottom of the adjusting plate 57, and the limiting plate 58 is rotatably connected to the adjusting plate 57 via a rotating shaft 511.

[0048] Several springs 510 are fixedly installed between the adjusting plate 57 and the limiting plate 58.

[0049] The obstruction plate 56 has an adjustable tilt angle, which extends the residence time of ore on the screen 2 through physical obstruction, thereby improving screening efficiency. Its rotating connection allows for dynamic adjustment of the obstruction strength according to the ore flow rate. The adjusting plate 57 and the limiting plate 58 are buffered by the ore impact through the spring 510 to avoid blockage. The rotating shaft structure of the limiting plate 58 can automatically adjust the opening and closing degree according to the ore accumulation height to maintain a stable throughput. At the same time, it can provide obstruction when cylindrical ore passes through, slowing down the movement speed of the ore at the top of the screen 2. When the jumping of the ore gets stuck in the gap between the limiting plate 58 and the screen 2, the limiting plate 58 rotates through the rotating shaft 511 and the adjusting plate 57. The distance between the limiting plate 58 and the screen 2 is increased. The adjusting plate 57 is made of metal. The side of the blocking plate 56 away from the screen 2 and the side of the adjusting plate 57 away from the screen 2 are on the same plane. The side of the blocking plate 56 near the screen 2 limits the adjusting plate 57, so that the blocking plate 56 and the adjusting plate 57 are on the same plane when stationary. The back of the adjusting plate 57 limits the limiting plate 58. The arrangement is the same as that of the blocking plate 56 and the adjusting plate 57. The spring 510 is located on the side of the limiting plate 58 and the adjusting plate 57 that is off-center. The spring 510 keeps the limiting plate 58 in close contact with the adjusting plate 57 when stationary.

[0050] The threaded engagement between the adjusting ball 55 and the threaded rod 54 converts the rotational motion of the threaded rod 54 into linear motion. The adjusting ball 55 and the blocking plate 56 rotate, causing the blocking plate 56 to rotate around the connection between the translation drive 59 and the blocking plate 56, thus changing the limiting tilt angle of the limiting plate 58.

[0051] The drive source 53 includes, but is not limited to, an electric motor, which is electrically connected to an external power source and is also controlled by an external PLC programming program. The drive source 53 drives the threaded rod 54 to rotate, and controls the tilt angle of the limiting plate 58 by adjusting the ball 55, thereby controlling the position of the limiting plate 58 to adapt to the needs of different screening stages.

[0052] The translation drive 59 includes, but is not limited to, an electric telescopic rod, which is electrically connected to an external power source and controlled by an external PLC programming program. The translation drive 59 supports the blocking plate 56 and transmits power to ensure its smooth adjustment.

[0053] A reinforcing rod 4 is fixedly installed in the middle of the top of the screen body 1, and a laser thickness gauge 7 is fixedly installed at the bottom of the reinforcing rod 4, with the laser thickness gauge 7 facing the screen 2.

[0054] The laser thickness gauge 7 emits a laser beam to the screen 2, calculates the thickness of the ore layer and the screen 2 by reflecting the light, and feeds the real-time data back to the control system to dynamically adjust the vibration frequency or the position of the baffle plate to prevent overload or insufficient screening, and to monitor the remaining thickness of the screen 2 in real time.

[0055] Several damping components 6 are fixedly installed at the four corners of the bottom of the screen body 1.

[0056] Damping component 6 includes, but is not limited to, rubber shock absorbers or hydraulic dampers. Damping component 6 is used to absorb the impact force generated by the vibration of the screen body, reduce the energy transmitted to the ground, reduce equipment noise, and protect the stability of the foundation.

[0057] Working principle: During use, the ore enters from the feed end of the screen body 1. Due to the inclined setting of the screen body 1 and the presence of a vibrating motor, the ore moves along the screen mesh 2 under the combined action of gravity and vibration. The vibration causes the ore particles to jump and separate into layers. Fine particles pass through the screen holes and become the undersize material, while large particles move along the screen surface to the end for discharge.

[0058] The baffle plate unit slows down the ore flow rate by physically blocking it, extending the screening time and improving the screening rate. The spring 510 buffers the ore impact and avoids material jamming. The limiting plate 58 can automatically adjust the opening and closing degree according to the ore accumulation to maintain a stable throughput. The adjusting ball 55 and the threaded rod 54 control the horizontal position and tilt angle of the baffle plate unit through the drive source 53 to adapt to different ore flow rates and ore shapes. The laser thickness gauge 7 monitors the ore layer thickness and the wear thickness of the screen 2 in real time. The damping component 6 absorbs the vibration energy of the screen body, reduces the impact transmitted to the foundation, reduces equipment noise, and extends the equipment life.

[0059] Example 2:

[0060] Please see Figure 2This embodiment is basically the same as the previous embodiment, except that the barrier plate unit includes an inclined plate 501 arranged at an angle, the power unit includes a power component 502, one side of the support rod 52 is fixedly connected to the power component 502, and the power component 502 is used to drive the inclined plate 501 to rotate around its own output shaft axis, thereby adjusting the tilt angle of the inclined plate 501.

[0061] The power component 502 includes, but is not limited to, a stepper motor, which is electrically connected to an external power source and controlled by an external PLC programming program. The output end of the power component 502 is fixedly connected to the top of the inclined plate 501. The rotation of the power component 502 drives the inclined plate 501 to rotate, thereby adjusting the distance between the bottom end of the inclined plate 501 and the screen 2.
