[0036] In order to facilitate understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0037] like Figures 1 to 8 As shown, the magnetic levitation vibrating screen device of the present invention includes a vibration component 1 and a bottom barrel 2, the vibration component 1 is arranged at the top of the bottom barrel 2, a screen component 3 is arranged on the top of the vibration component 1, and a screen frame component 4 is arranged on the top of the vibration component 1 outside the screen component 3. The material to be screened is added into the screen frame component 4, so that the material falls on the screen component 3. At this time, the screen component 3 and the screen frame component 4 are vibrated together with the assistance of the vibration component 1, and the material is screened with the assistance of the screen component 3 with the assistance of the vibration.

[0038] The vibration component 1 includes a base 101 and a vibration plate 103. A power-carrying coil 102 is arranged on the top of the base 101, and a magnetic block 104 is arranged at the lower end of the vibration plate 103. The base 101 is arranged on the top of the bottom barrel 2. Copper wire is wound around the power-carrying coil 102. When the copper wire in the power-carrying coil 102 is energized, a magnetic field opposite to the magnetic block 104 is formed. Under the influence of the magnetic field, an upward repulsive force is generated on the magnetic block 104, thereby causing the vibration plate 103 to move upward. There are four power-carrying coils 102. When the four power-carrying coils 102 are energized respectively in a set order, the magnetic repulsive force of the magnetic block 104 generated by the generated magnetic field will change, thereby causing the magnetic block 104 to move up and down, thereby causing the vibration plate 103 to vibrate to form magnetic suspension vibration.

[0039] The screen frame assembly 4 comprises an upper screen frame 401 and a lower screen frame 402. A conical block 403 is arranged at the inner bottom of the lower screen frame 402. A sleeve 404 is rotatably arranged at the top of the center of the conical block 403. A scraper 405 is arranged on the side end of the sleeve 404 on the surface of the conical block 403. A round rod 406 is arranged at the center of the sleeve 404. The bottom of the round rod 406 passes through the vibration plate 103 and is fixed to the center of the base 101. A stirring plate 407 is arranged at the top of the round rod 406. A cleaning brush 408 is arranged at the lower end of the stirring plate 407. The vibration plate 103 is arranged at the lower end of the conical block 403. The mesh assembly 3 is located in the upper screen frame 401. After the material falls on the screen assembly 3, the material is limited with the assistance of the upper screen frame 401. After the screening is completed, the coarse material still remains in the upper screen frame 401, while the fine material falls on the conical block 403 in the lower screen frame 402. With the assistance of the conical block 403, the fine material is close to the side wall of the lower screen frame 402. Under the action of vibration, the round rod 406 and the sleeve 404 will have relative displacement, so that the scraper 405 can scrape off the fine material on the conical block 403, so that the fine material is closer to the edge of the lower screen frame 402.

[0040] The round rod 406 passes through the conical block 403, and the round rod 406 slides up and down in the conical block 403 and the sleeve 404. The inner wall of the sleeve 404 is provided with a lower wedge block 409 and an upper wedge block 410, and the outer side of the round rod 406 is provided with a matching block 411 at the corresponding position of the sleeve 404. When the round rod 406 and the sleeve 404 are relatively displaced, the sleeve 404 is rotated with the assistance of the upper wedge block 410, the lower wedge block 409 and the matching block 411. The rotation of the sleeve 404 can rotate the scraper 405, so that the scraper 405 scrapes the fine material on the conical block 403, and the rotation of the sleeve 404 can rotate the screen assembly 3, so that the material on the screen assembly 3 is rotated, and the material is stirred with the assistance of the stirring plate 407 when rotating, so that the filtering of the material is smoother.

[0041] The screen assembly 3 is arranged on the top of the sleeve 404, the round rod 406 passes through the screen assembly 3, the stirring plate 407 is located at the upper end of the screen assembly 3, and when the lower screen frame 402 vibrates with the vibration plate 103, the screen assembly 3 will also vibrate with the assistance of the sleeve 404, which is beneficial to screening the material.

[0042] A coarse material discharge pipe 412 is arranged at the side end of the upper screen frame 401, and a fine material discharge pipe 413 is arranged at the side end of the lower screen frame 402. Movable baffles are arranged at the connection between the coarse material discharge pipe 412 and the upper screen frame 401, and at the connection between the fine material discharge pipe 413 and the lower screen frame 402. After the material screening is completed, the movable baffles are removed, and the coarse material in the upper screen frame 401 can be discharged through the coarse material discharge pipe 412, and the fine material in the lower screen frame 402 can be discharged through the fine material discharge pipe 413, thereby improving the convenience of equipment use.

[0043] A limiting rod 414 is provided at the side end of the lower screen frame 402, and a fixing tube 415 is sleeved on the limiting rod 414. A fixing rod 416 is provided on the top of the fixing tube 415. A fixing block 417 is provided at the side end of the upper screen frame 401. The fixing rod 416 passes through the fixing block 417, and a fixing nut 418 is provided on the top of the fixing rod 416. The lower end of the fixing rod 416 is sleeved on the limiting rod 414 through the fixing tube 415, and then the upper end of the fixing rod 416 is inserted into the fixing block 417, and the fixing nut 418 is rotated to connect and fix the upper screen frame 401 and the lower screen frame 402 to avoid separation of the upper screen frame 401 and the lower screen frame 402 due to vibration.

[0044] A conical dust cover 419 is provided on the top of the upper screen frame 401, a hopper 420 is provided at the center of the top of the conical dust cover 419, and an observation window 421 is provided on the upper end of the side of the conical dust cover 419. The hopper 420 is used to make the addition of materials smoother, and the conical dust cover 419 is used to prevent foreign impurities from entering the materials in the upper screen frame 401. The screening status in the upper screen frame 401 can be observed with the help of the observation window 421.

[0045] There is a distance between the stirring plate 407 and the screen assembly 3. The screen assembly 3 includes a screen body 301. The screen body 301 is arranged on the top of the sleeve 404. The screen body 301 is elastic. A pressure sensor is arranged on the side end of the stirring plate 407. When the screen body 301 vibrates, the material on the screen body 301 will be stirred due to its elasticity, so that the screening effect is better. In addition, since the screen body 301 is elastic, the probability of its blockage will be reduced as the screen body 301 vibrates.

[0046] During the use of the magnetic levitation vibrating screen device of the present invention, the sieve holes of the screen body 301 are easily blocked by materials, thereby reducing its screening efficiency. In addition, when the coarse and fine materials after screening are discharged only by vibration, residues are likely to remain in the equipment, and the fine materials in the lower screen frame 402 are likely to adhere to the conical block 403, making it difficult to discharge the fine materials. Therefore, the following solution is proposed.

[0047] When the magnetic levitation vibrating screen device of the present invention is in use, the material is first added with the assistance of the hopper 420, and the material added through the hopper 420 enters the upper screen frame 401, and the material will fall on the upper end of the screen body 301, and then the four energized coils 102 are energized in turn in a clockwise order, so that a changing magnetic field is generated at the four energized coils 102, and the magnetic block 104 is affected by the change in the magnetic field and moves up and down, thereby causing the vibration plate 103 to move up and down and vibrate.

[0048] The vibration of the vibration plate 103 will drive the vibration of the conical block 403, and the vibration of the conical block 403 will drive the vibration of the screen body 301 with the assistance of the sleeve 404. When the screen body 301 vibrates, the material above the screen body 301 will be turned over and stirred, which is beneficial for screening the material. The screen body 301 itself has elasticity. When the screen body 301 vibrates up and down, it will deform, which is beneficial for avoiding material blockage. At the same time, the up and down vibration of the conical block 403 is beneficial for the fine material on the conical block 403 to fall, which is beneficial for the discharge of the fine material.

[0049] When the conical block 403 vibrates up and down, the sleeve 404 moves up and down, so the sleeve 404 and the round rod 406 are relatively displaced. When the sleeve 404 and the round rod 406 are relatively displaced, the sleeve 404 is rotated with the assistance of the upper wedge block 410, the lower wedge block 409 and the matching block 411. The rotation of the sleeve 404 drives the rotation of the scraper 405. When the scraper 405 rotates along the surface of the conical block 403, the scraper 405 scrapes off the fine material remaining on the surface of the conical block 403, so that the fine material is close to the inner wall of the lower screen frame 402, which is conducive to the discharge of the fine material.

[0050] When the sleeve 404 rotates, the sleeve 404 will also drive the rotation of the screen body 301. The rotation of the screen body 301 will cause the stirring plate 407 to stir the material on the top of the screen body 301, which is conducive to the screen body 301 to screen the material and improve the screening efficiency of the equipment.

[0051] The screen body 301 is rotating while vibrating up and down, so the distance between the screen body 301 and the stirring plate 407 will also change, so that the stirring depth of the material on the screen body 301 by the stirring plate 407 changes, thereby making the stirring effect of the material stronger and the screening efficiency of the screen body 301 higher.

[0052] When the stirring plate 407 is stirring, the pressure sensor will detect the pressure value. The larger the detection value of the pressure sensor is, the more material is on the screen body 301. When the detection value of the pressure sensor increases, the equipment controls the power intensity of the energized coil 102 to increase, so that the magnetic field generated after the energized coil 102 is energized is enhanced. Therefore, the up and down vibration intensity of the vibration plate 103 will be strengthened, the up and down moving distance of the vibration plate 103 will also increase, and the up and down moving distance of the screen body 301 will also increase. At this time, when the screen body 301 moves up and down and vibrates, the cleaning brush 408 at the lower end of the stirring plate 407 will also be inserted into the sieve holes on the screen body 301, so as to clean the materials blocked in the sieve holes of the screen body 301, thereby ensuring the screening effect and efficiency of the screen body 301.

[0053] During the discharge of fine material, the energized coil 102 on the side away from the fine material discharge pipe 413 will continue to be energized, so that the lower screen frame 402 on the side away from the fine material discharge pipe 413 is higher than the side close to the fine material discharge pipe 413. At this time, when the remaining energized coils 102 are energized in a cycle, the vibration generated by the vibrating plate 103 drives the vibration of the conical block 403, and the fine material close to the inner wall of the lower screen frame 402 will move toward the fine material discharge pipe 413, thereby making the discharge of fine material smoother.

[0054] The main functions achieved by the present invention are: by setting components such as scraper 405, sleeve 404, round rod 406, upper wedge block 410 and lower wedge block 409, the sleeve 404 is moved up and down with the assistance of vibration component 1, and the sleeve 404 is rotated with the cooperation of upper wedge block 410, lower wedge block 409 and matching block 411, so that the scraper 405 can scrape the fine material on the conical block 403, and the stirring plate 407 can stir the material on the top of the screen body 301, so that the screening effect of the screen body 301 is better. At the same time, the amount of material on the screen body 301 can be detected with the assistance of pressure sensor, so as to adjust the vibration intensity of the equipment to ensure the screening efficiency of the material. At the same time, when the screen body 301 moves up and down, the cleaning brush 408 will enter the screen hole of the screen body 301, so as to dredge and clean the blocked screen hole of the screen body 301.

[0055] The present invention also provides a method for using the magnetic suspension vibrating screen device, comprising the following steps:

[0056] Step 1: First, add the material to the top of the screen assembly 3 through the hopper 420, and limit the material with the assistance of the upper screen frame 401.

[0057] Step 2: With the assistance of the vibration assembly 1, the conical block 403 is moved up and down and vibrated, thereby causing the screen assembly 3 to vibrate.

[0058] Step 3: When the equipment vibrates, the scraper 405 and the screen assembly 3 will rotate. The rotation of the scraper 405 will scrape the fine material on the surface of the conical block 403, and the rotation of the screen assembly 3 will cause the stirring plate 407 to stir the material, making its screening efficiency stronger.

[0059] Step 4: After the material screening is completed, the fine material in the lower screen frame 402 is discharged through the fine material discharge pipe 413, and the coarse material in the upper screen frame 401 is discharged through the coarse material discharge pipe 412.

[0060] The installation, connection or setting methods of the screen assembly 3 and the magnetic suspension vibrating screen device of the present invention are all common mechanical methods, and can be implemented as long as they can achieve their beneficial effects.
