Description

Technical Field

[0001] The utility model relates to the technical field of vibrating screens, in particular to an ultrasonic vibrating screen. Background Art

[0002] Screening of ultrafine powder by an ultrasonic vibrating screen is a common separation process for particles of different sizes, mainly for separating large particle materials. After batch mixing, the material reaches the vibrating screen through the feed inlet. The ultrasonic vibrating screen generates a low-amplitude and high-frequency vibration on the screen mesh through ultrasonic transducers, so that the material on the screen mesh basically remains suspended on the screen mesh, and then passes through the vibrating screen to achieve the screening effect.

[0003] During material screening, operators often directly pour the raw materials into the ultrasonic vibrating screen, resulting in uneven distribution of the materials on the screen mesh. And when the screen mesh of the ultrasonic vibrating screen needs to be replaced, it is necessary to disassemble the ultrasonic vibrating screen layer by layer to facilitate the replacement of the screen mesh, resulting in low screening efficiency and reduced production efficiency. Summary of the Utility Model

[0004] In order to overcome the shortcomings of the prior art, this application provides an ultrasonic vibrating screen.

[0005] An ultrasonic vibrating screen provided by this application adopts the following technical solutions:

[0006] An ultrasonic vibrating screen includes an ultrasonic vibrating screen body. A hopper is connected and arranged at the top of the ultrasonic vibrating screen body. A base is arranged at the bottom of the ultrasonic vibrating screen body. A support frame is arranged on the base. A screen-changing component for facilitating the replacement of the screen mesh is arranged on the support frame. A material-uniforming component is arranged inside the hopper. The material-uniforming component includes a material-uniforming plate and a rotating shaft. Three through holes are coaxially and evenly formed in the material-uniforming plate. The rotating shaft is coaxially and rotatably arranged on the material-uniforming plate. Three blocking plates are coaxially arranged on the rotating shaft. The three blocking plates correspond to the three through holes one by one. The blocking plates are used to block the through holes. A driving component for driving the rotating shaft to rotate reciprocally is arranged on the support frame.

[0007] By adopting the above technical solutions, the raw materials to be screened are poured into the hopper, and then the driving component is used to drive the rotating shaft to rotate reciprocally, thereby driving the three blocking plates to rotate reciprocally, so that the raw materials slowly pass through the three through holes at certain intervals and then fall onto the screen mesh, thus avoiding excessive accumulation of raw materials on the screen mesh at one time to a certain extent and enabling the raw materials to be more evenly distributed on the screen mesh, improving the screening efficiency and quality.

[0008] Optionally, the driving assembly includes a slide rail, a gear, and a rack. The slide rail is fixedly arranged on the top of the ultrasonic vibrating screen body. The rack is slidably arranged in the slide rail. The gear is rotatably arranged at the bottom of the hopper, and the inner wall of the gear is connected to one end of the blocking plate away from the rotating shaft. The gear meshes with the rack. A driving motor is also arranged on the top of the ultrasonic vibrating screen body. A driving rod is coaxially arranged on the output shaft of the driving motor. Driving blocks are arranged at both ends of the driving rod. A driven shaft is rotatably arranged on the top of the ultrasonic vibrating screen body. A driven rod in an "L" shape is arranged on the driven shaft. The driving block is slidably connected to the driven rod. Driven blocks are arranged at both ends of the rack. The driven rod is slidably connected to the driven block away from the driving motor.

[0009] By adopting the above technical solution, the driving assembly drives the rotating shaft to rotate reciprocally, thereby driving the three blocking plates to rotate reciprocally, so that the blocking plates periodically open the through holes at intervals, and further enabling the raw materials to fall onto the screen more evenly, to a certain extent avoiding the accumulation of raw materials on the screen and affecting the screening efficiency.

[0010] Optionally, three dredging rods are coaxially arranged on the rotating shaft. The three dredging rods correspond to the three groups of through holes one by one, and the dredging rods are located on one side of a group of through holes.

[0011] By adopting the above technical solution, the dredging rod moves from one side to the other side of a group of through holes, thereby pushing the raw materials located at the top position of the through holes, and grinding the large-particle raw materials to a certain extent, so as to facilitate the raw materials to fall from the through holes onto the screen for screening.

[0012] Optionally, a plurality of flexible brush hairs are evenly arranged at the bottom of the dredging rod. The flexible brush hairs are slidably connected to the material leveling plate.

[0013] By adopting the above technical solution, when the flexible brush hairs move to the through holes, the flexible brush hairs will extend into the through holes, thereby dredging the through holes, and to a certain extent avoiding the blockage of the through holes and affecting the feeding effect of the raw materials.

[0014] Optionally, a scraping seat is coaxially arranged on the rotating shaft. Three scraping plates are evenly arranged on the scraping seat. The three scraping plates correspond to the three groups of through holes one by one, and the scraping plates are located directly above the through holes.

[0015] By adopting the above technical solution, during the movement of the scraping plate, the raw materials located between two groups of through holes will be pushed onto the through holes, so as to facilitate the subsequent falling of the raw materials through the through holes.

[0016] Optionally, the screen-changing component includes a mounting frame. A lifting groove is vertically formed in the support frame. A lifting block is slidably arranged in the lifting groove. The mounting frame is arranged on the lifting block. A plurality of mounting grooves for placing vibrating screens are evenly formed in the ultrasonic vibrating screen body. A mounting frame is slidably arranged on the mounting frame. The mounting frame is used for placing a screen mesh. The mounting frame is inserted into the mounting groove. Mounting blocks are arranged at both ends of the mounting frame. Limiting seats are arranged on both sides of the mounting groove. The mounting blocks are detachably arranged on the limiting seats.

[0017] By adopting the above technical solution, separating the mounting block from the limiting seat can facilitate moving the mounting frame out of the mounting groove along the length direction of the mounting frame to the outside of the ultrasonic vibrating screen body, and further moving the screen mesh out of the ultrasonic vibrating screen body, so that the staff can conveniently replace the screen mesh.

[0018] Optionally, a locking screw is arranged on the limiting seat. A mounting hole is formed in the mounting block. The locking screw is in threaded connection with the mounting hole.

[0019] By adopting the above technical solution, when the staff moves the mounting block to the limiting seat, rotate the locking screw to make the locking screw in threaded connection with the mounting hole, thereby fixedly mounting the mounting block on the limiting seat.

[0020] Optionally, a holding frame is hingedly arranged at one end of the mounting frame away from the ultrasonic vibrating screen. A positioning rod is slidably arranged inside the mounting frame. A positioning hole is formed in the limiting seat. The positioning rod is inserted into the positioning hole. A positioning block in an arc shape is arranged at one end of the positioning rod away from the positioning hole. A return spring is sleeved on the positioning rod. One end of the return spring is connected to the positioning block and the other end is connected to the mounting frame. One end of the holding frame close to the mounting frame is used to push the positioning rod to slide.

[0021] By adopting the above technical solution, rotate the holding frame to rotate the holding frame from the vertical direction to the horizontal direction. During the rotation of the holding frame, the holding frame will press the positioning block, the return spring will be compressed, and the positioning rod will extend. When the positioning rod is inserted into the positioning hole on the limiting seat, the mounting frame is aligned with the mounting frame where the screen mesh needs to be replaced.

[0022] Optionally, a shock-absorbing spring is arranged on the lifting block. The other end of the shock-absorbing spring is connected to the bottom of the mounting frame.

[0023] By adopting the above technical solution, a relatively stable connection is maintained between the mounting frame and the ultrasonic vibrating screen body, which is convenient for the staff to move the mounting frame and replace the screen mesh.

[0024] Optionally, a sealing gasket is arranged at one end of the mounting frame away from the ultrasonic vibrating screen body.

[0025] By adopting the above technical solution, after the installation frame with the screen is inserted into the installation groove, the sealing gasket contacts the outer wall of the ultrasonic vibrating screen body, thus to a certain extent preventing the raw materials inside the ultrasonic vibrating screen body from leaking out through the gap between the installation frame and the ultrasonic vibrating screen body.

[0026] The utility model has the following advantages:

[0027] 1. By arranging the material leveling component, the raw materials in the hopper can be slowly added onto the screen and fall on the screen more evenly, thus improving the screening effect of the raw materials;

[0028] 2. By arranging the screen changing component, the screen can be replaced more conveniently, thus saving the time for replacing the screen and improving the work efficiency;

[0029] 3. By arranging the shock-absorbing springs, the connection stability between the mounting frame and the ultrasonic vibrating screen body can be improved, facilitating the replacement of the screen. Description of the Drawings

DETAILED DESCRIPTION

[0037] The present invention is further described below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0038] like Figures 1 to 6 As shown, an ultrasonic vibration screen comprises an ultrasonic vibration screen body 1, a hopper 11 is connected to the top of the ultrasonic vibration screen body 1, a base 12 is installed at the bottom of the ultrasonic vibration screen body 1, a support frame 13 is installed on the base 12, a screen changing assembly 2 for facilitating replacement of a screen 26 is installed on the support frame 13, a material distribution assembly 3 is installed inside the hopper 11, the material distribution assembly 3 comprises a material distribution plate 31 and a rotating shaft 32, three groups of through holes 33 are coaxially and evenly opened on the material distribution plate 31, the rotating shaft 32 is coaxially rotatably installed on the material distribution plate 31, three blocking plates 34 are coaxially installed on the rotating shaft 32, the three blocking plates 34 correspond to the three groups of through holes 33 one by one, the blocking plates 34 are used to block the through holes 33, and a driving assembly 4 for driving the rotating shaft 32 to reciprocate is installed on the support frame 13 ; Since the ultrasonic vibration screen body 1 is a prior art, the specific structure of the ultrasonic vibration screen body 1 is not described in detail one by one in this embodiment. When in use, the raw material to be screened is poured into the hopper 11, and then the driving component 4 drives the rotating shaft 32 to rotate reciprocatingly, thereby driving the three blocking plates 34 to rotate reciprocatingly, and then the raw material slowly and at a certain interval passes through the three groups of through holes 33 and then falls onto the screen 26, thereby to a certain extent avoiding excessive accumulation of raw materials on the screen 26 at one time, and allowing the raw materials to be more evenly distributed on the screen 26, thereby improving the efficiency and quality of screening; when the screen 26 has been used for a certain period of time, the screen 26 can be quickly and conveniently replaced through the screen changing component 2, thereby reducing the screen changing time and improving production efficiency.

[0039] like Figures 1 to 6As shown in the figure, the driving assembly 4 includes a slide rail 41, a gear 42 and a rack 43. The slide rail 41 is fixedly installed on the top of the ultrasonic vibrating screen body 1. The rack 43 is slidably installed in the slide rail 41. The gear 42 is rotatably installed at the bottom of the hopper 11, and the inner wall of the gear 42 is connected to one end of the plugging plate 34 away from the rotating shaft 32. The gear 42 meshes with the rack 43. A driving motor 44 is also installed on the top of the ultrasonic vibrating screen body 1. A driving rod 45 is coaxially installed on the output shaft of the driving motor 44. Driving blocks 451 are installed at both ends of the driving rod 45. A driven shaft 46 is rotatably installed on the top of the ultrasonic vibrating screen body 1. A driven rod 461 in an "L" shape is installed on the driven shaft 46. The driving block 451 is slidably connected to the driven rod 461. Driven blocks 431 are installed at both ends of the rack 43. The driven rod 461 is slidably connected to the driven block 431 away from the driving motor 44. During use, the driving motor 44 is started. During the rotation of the driving motor 44, the driving rod 45 will be driven to rotate synchronously. During the rotation of the driving rod 45, the two driving blocks 451 will be driven to rotate synchronously. During the movement of the driving block 451, one end of the driven rod 461 in an "L" shape will be pressed, so as to drive the driven shaft 46 and the driven rod 461 to rotate, and then the other end of the driven rod 461 will rotate in a direction away from the driving rod 45. During the rotation of the other end of the driven rod 461, the driven rod 461 will push the driven block 431 to move, so as to drive the rack 43 to move along the length direction of the slide rail 41. During the movement of the rack 43, the gear 42 will be driven to rotate. During the rotation of the gear 42, the plugging plate 34 and the rotating shaft 32 will be driven to rotate synchronously, so that the plugging plate 34 will move to a position away from the through hole 33, and the raw materials in the hopper 11 will be able to fall. As the driving rod 45 continues to rotate, the driving rod 45 will move away from the driven rod 461, then contact the driven block 431 at one end of the rack 43 close to the driving rod 45, and push the rack 43 to move in the opposite direction, and finally separate from the driven block 431. During the movement of the rack 43, the gear 42 will be driven to move in the opposite direction, so that the plugging plate 34 will plug the through hole 33 to prevent too much raw material from falling into the screen 26. During the rotation of the driving motor 44, the rack 43 is driven to move back and forth, so that the plugging plate 34 periodically opens the through hole 33 at intervals, and then the raw materials fall onto the screen 26 more evenly, to a certain extent avoiding the accumulation of raw materials on the screen 26 and affecting the screening efficiency.

[0040] As Figures 1 to 6As shown in the figure, three dredging rods 35 are coaxially installed on the rotating shaft 32. The three dredging rods 35 correspond to the three groups of through holes 33 one by one, and the dredging rods 35 are located on one side of the through holes 33. When the driving assembly 4 drives the rotating shaft 32 and the blocking plate 34 to rotate synchronously, the blocking plate 34 moves away from the through hole 33. At this time, the dredging rod 35 moves from one side of a group of through holes 33 to the other side, so as to push the raw materials located at the top of the through hole 33, and to a certain extent, grind the large-particle raw materials, so that the raw materials can fall from the through hole 33 onto the screen 26 for screening. When the rotating shaft 32 rotates in the opposite direction, the blocking plate 34 will move towards the position close to the through hole 33, so as to block the through hole 33, and the dredging rod 35 will move away from the through hole 33. When the rotating shaft 32 rotates back and forth, the dredging rod 35 will also move back and forth, so as to a certain extent, repeatedly grind the large-particle raw materials located at the top of the through hole 33, and to a certain extent, prevent the large-particle raw materials from blocking the through hole 33, and play a certain role in dredging the through hole 33.

[0041] As Figures 1 to 6 shown, a plurality of flexible bristles 351 are uniformly installed at the bottom of the dredging rod 35, and the flexible bristles 351 are slidably connected to the material leveling plate 31. By uniformly installing a plurality of flexible bristles 351 at the bottom of the dredging rod 35, when the driving assembly 4 drives the dredging rod 35 to move back and forth, when the flexible bristles 351 move to the through hole 33, the flexible bristles 351 will extend into the through hole 33, so as to dredge the through hole 33, and to a certain extent, prevent the through hole 33 from being blocked and affecting the feeding effect of the raw materials.

[0042] As Figures 1 to 6 shown, a scraping seat 36 is coaxially installed on the rotating shaft 32. Three scraping plates 361 are uniformly installed on the scraping seat 36. The three scraping plates 361 correspond to the three groups of through holes 33 one by one, and the scraping plates 361 are located directly above the through holes 33. There is a certain angle between the scraping plate 361 and the dredging rod 35. When the driving assembly 4 drives the blocking plate 34 to move towards the position close to the through hole 33, it will drive the scraping seat 36 and the scraping plates 361 to move synchronously. During the movement of the scraping plates 361, the raw materials located between the two groups of through holes 33 will be pushed onto the through holes 33, so as to facilitate the subsequent falling of the raw materials through the through holes 33. When the driving assembly 4 drives the blocking plate 34 to move away from the through hole 33, the raw materials located on the through hole 33 will be able to fall through the through hole 33 onto the screen 26, and the scraping plates 361 will move to the position between the two groups of through holes 33, so as to facilitate the next pushing of the raw materials.

[0043] As Figures 1 to 6As shown, the screen changing component 2 includes a mounting frame 21. A lifting groove 22 is vertically formed on the support frame 13. A lifting block 23 is slidably mounted in the lifting groove 22. The mounting frame 21 is mounted on the lifting block 23. A plurality of mounting grooves 24 for placing vibrating screens are evenly formed on the ultrasonic vibrating screen body 1. A mounting frame 25 is slidably mounted in the mounting groove 24. The mounting frame 25 is used for placing a screen mesh 26. The mounting frame 25 is inserted into the mounting groove 24. Mounting blocks 27 are mounted at both ends of the mounting frame 25. The mounting blocks 27 are slidably connected to the top of the mounting frame 21. Limiting seats 28 are mounted on both sides of the ultrasonic vibrating screen body 1 and located on both sides of the mounting groove 24. The mounting blocks 27 are detachably mounted on the limiting seats 28. By evenly forming a plurality of mounting grooves 24 on the ultrasonic vibrating screen body 1, a mounting frame 25 is mounted in each mounting groove 24, and a screen mesh 26 is placed on each mounting frame 25. The plurality of screen meshes 26 can improve the screening effect of raw materials. Moreover, when a certain screen mesh 26 needs to be replaced, since there are still a plurality of screen meshes 26 that can work, to a certain extent, it does not affect the normal operation of the ultrasonic vibrating screen body 1. Connect one end of the mounting frame 21 to the limiting seat 28 and fix the current position of the mounting frame 21. Then separate the mounting block 27 from the limiting seat 28, so that the mounting frame 25 can be conveniently removed from the mounting groove 24, and further the screen mesh 26 can be removed outside the ultrasonic vibrating screen body 1, and the staff can conveniently replace the screen mesh 26.

[0044] As Figures 1 to 6 As shown, a locking screw 5 is mounted on the limiting seat 28. A mounting hole 51 is formed on the mounting block 27. The locking screw 5 is in threaded connection with the mounting hole 51. When the staff moves the mounting block 27 to the limiting seat 28, rotate the locking screw 5 to make the locking screw 5 in threaded connection with the mounting hole 51, so as to fixedly mount the mounting block 27 on the limiting seat 28.

[0045] As Figures 1 to 6As shown, one end of the mounting frame 21 away from the ultrasonic vibrating screen body 1 is hingedly installed with a holding frame 52. A positioning rod 53 is slidably installed inside the mounting frame 21. A positioning hole 54 is formed in the limit seat 28. The positioning rod 53 is inserted into the positioning hole 54. One end of the positioning rod 53 away from the positioning hole 54 is installed with an arc-shaped positioning block 55. A return spring 56 is sleeved on the positioning rod 53. One end of the return spring 56 is connected to the positioning block 55 and the other end is connected to the mounting frame 21. One end of the holding frame 52 close to the mounting frame 21 is used to push the positioning rod 53 to slide. During use, the staff holds the holding frame 52, so as to facilitate controlling the mounting frame 21 to slide along the length direction of the lifting groove 22. When the staff aligns the mounting frame 21 with the limit seats 28 on both sides of the mounting groove 24 where the screen 26 needs to be replaced, rotate the holding frame 52, and rotate the holding frame 52 from the vertical direction to the horizontal direction. During the rotation of the holding frame 52, the holding frame 52 will press the positioning block 55, the return spring 56 will be compressed, and the positioning rod 53 will extend. When the positioning rod 53 is inserted into the positioning hole 54 on the limit seat 28, the mounting frame 21 is aligned with the mounting frame 25 where the screen 26 needs to be replaced. Then loosen the locking screw 5 on the mounting block 27 to make the locking screw 5 away from the mounting hole 51. Then slide the mounting block 27 along the length direction of the mounting frame 21, so that the mounting frame 25 and the screen 26 to be replaced move to a position away from the ultrasonic vibrating screen body 1, so as to facilitate the staff to replace the screen 26 placed on the mounting frame 25. After the replacement is completed, the staff moves the mounting frame 25 and the mounting block 27 along the length direction of the mounting frame 21, and inserts the mounting frame 25 and the screen 26 into the mounting groove 24. When the mounting block 27 slides to the top of the limit seat 28, thread the locking screw 5 on the mounting block 27 with the mounting hole 51 on the limit seat 28, so as to install and fix the mounting frame 25 and the screen 26 on the ultrasonic vibrating screen body 1.

[0046] As Figures 1 to 6 shown, a shock-absorbing spring 57 is installed on the lifting block 23, and the other end of the shock-absorbing spring 57 is connected to the bottom of the mounting frame 21. When it is necessary to replace the screen 26 while the ultrasonic vibrating screen body 1 is working, after inserting the positioning rod 53 in the mounting frame 21 into the positioning hole 54 on the limit seat 28, due to the vibration and shaking generated during the working process of the ultrasonic vibrating screen body 1, it is not convenient for the staff to take out the mounting frame 25 and the screen 26 from the ultrasonic vibrating screen body 1. The mounting frame 21 is connected to the lifting block 23 through the shock-absorbing spring 57. Therefore, during the vibration or shaking of the ultrasonic vibrating screen body 1, the mounting frame 21 can shake synchronously with the ultrasonic vibrating screen body 1 within a certain range, so as to keep a relatively stable connection between the mounting frame 21 and the ultrasonic vibrating screen body 1, which is convenient for the staff to move the mounting frame 25 and replace the screen 26.

[0047] As Figures 1 to 6 shown, a gasket 58 is installed at one end of the mounting frame 25 away from the ultrasonic vibrating screen body 1; by adhesively mounting the gasket 58 on the mounting frame 25, after the mounting frame 25 with the screen mesh 26 is inserted into the mounting groove 24, the gasket 58 contacts the outer wall of the ultrasonic vibrating screen body 1, thereby to a certain extent preventing the raw materials inside the ultrasonic vibrating screen body 1 from leaking out through the gap between the mounting frame 25 and the ultrasonic vibrating screen body 1. In this embodiment, the gasket 58 is made of rubber material.

[0048] The implementation principle of this embodiment is as follows: the raw materials to be screened are poured into the hopper 11, and then the driving assembly 4 is used to drive the rotating shaft 32 to rotate reciprocally, thereby driving the three blocking plates 34 to rotate reciprocally, and further enabling the raw materials to pass through the three groups of through holes 33 slowly and at certain intervals and then fall onto the screen mesh 26, thereby to a certain extent preventing the raw materials from piling up too much on the screen mesh 26 at one time and enabling the raw materials to be more evenly distributed on the screen mesh 26, improving the screening efficiency and quality; when the screen mesh 26 is used for a certain period of time, the screen mesh 26 can be quickly and conveniently replaced through the screen changing assembly 2, thereby reducing the screen changing time and improving the production efficiency.

[0049] The above is only the preferred embodiment of the present utility model and does not impose any form of limitation on the present utility model. Any person skilled in the art can make many possible changes and modifications to the technical solution of the present utility model or modify it into an equivalent embodiment with equivalent changes without departing from the scope of the technical solution of the present utility model. Therefore, all changes, modifications, equivalent changes and modifications made to the above embodiments based on the technical solution of the present utility model without departing from the content of the technical solution of the present utility model fall within the protection scope of this technical solution.
