Description

Technical Field

[0001] The present application relates to the field of screening technology, and in particular to a vibrating screening device. Background Art

[0002] NdFeB permanent magnet material has excellent properties such as high magnetic energy product and high remanence, but its hardness is relatively low and it is easy to break. It is easy to bump and cause chipping during production or use. Therefore, NdFeB needs to be chamfered during the production process. During the chamfering process, NdFeB, abrasive and chamfering water are added to the vibration chamfering equipment together. After the chamfering is completed, the NdFeB product needs to be separated from the abrasive.

[0003] There is a vibrating screening device for separating NdFeB products from abrasives. The screening device includes a frame and a screen, and the frame is provided with a vibration motor. During separation, a mixture of NdFeB, abrasives and chamfering water is transported to the screen together, and the vibration motor is started. Then, the chamfering water and NdFeB products are screened to the bottom of the screen, while the abrasives remain on the screen. The screening device can effectively complete the screening of NdFeB and abrasives.

[0004] When using the above-mentioned vibration screening equipment, the screen is prone to damage as the use time increases, and needs to be replaced after damage. However, in the above-mentioned vibration screening equipment, the screen is usually fixed to the frame with multiple bolts. When removing the screen, the multiple bolts need to be unscrewed one by one. After replacing the new screen, the multiple bolts need to be tightened one by one. The disassembly and assembly process is relatively time-consuming, resulting in low disassembly and assembly efficiency of the screen. Utility Model Content

[0037] The frame 1 has a screening slot 11, and the two opposite inner slot walls of the screening slot 11 are fixedly connected with a support edge 12, and the support edge 12 is extended along the length direction of the screening slot 11. The screen 2 is mounted on the support edge 12, and the screen 2 divides the slot space of the screening slot 11 into an upper abrasive slot 111 and a lower product slot 112. A feed port 13 is provided at one end of the frame 1, and the feed port 13 is connected to the abrasive slot 111; a water outlet 14 is provided on the side wall of the other end of the frame 1, and the water outlet 14 is connected to the product slot 112. A vibration motor 3 is fixed below the frame 1.

[0038] The fixing assembly 4 is used to fix the screen 2 to the supporting edge 12. The fixing assembly 4 is provided in multiple groups, and the multiple groups of fixing assemblies 4 are arranged on both sides of the screening slot 11.

[0039] Reference Figure 1 and Figure 2 The fixed assembly 4 includes a support seat 41, a movable member 42, a linkage member 43, a connecting member 44 and an abutting member 45. The support seat 41 is fixedly connected to the slot wall of the screening slot 11. One end of the movable member 42 is hinged to the support seat 41, and the other end is a handle. One end of the linkage member 43 is hinged to the middle of the movable member 42, and one end of the connecting member 44 is hinged to the end of the linkage member 43 away from the movable member 42. The linkage member 43 has a limiting surface 431, and the limiting surface 431 is used to abut against the upper surface of the connecting member 44. The abutting member 45 is connected to the connecting member 44, and the abutting member 45 is used to abut against the screen 2. When the fixing assembly 4 clamps the screen 2 to the supporting edge 12, the abutment 45, the linkage member 43 and the movable member 42 are all arranged vertically, the connecting member 44 is arranged horizontally, and the limiting surface 431 abuts against the connecting member 44; when replacing the screen 2, the staff holds the handle and rotates the movable member 42 relative to the supporting seat 41, the movable member 42 drives the linkage member 43 to rotate, the linkage member 43 loses the abutment with the connecting member 44 and drives the connecting member 44 to rotate upward, thereby driving the abutment 45 to rotate upward, releasing the limit between the abutment 45 and the screen 2, compared with the operation of tightening the bolt, it saves time and effort, and effectively improves the replacement efficiency of the screen 2.

[0040] Specifically, in this embodiment, the abutment 45 is a screw rod, the connecting member 44 is connected to a nut 441, and the abutment 45 is threadedly connected to the nut 441, so that the end position of the abutment 45 is adjustable to adapt to screens 2 of different thicknesses or to facilitate reinforcement of the screen 2.

[0041] Sliding grooves 442 are provided on both sides of the nut 441, and the nut 441 is slidingly connected to the connecting member 44 through the sliding grooves 442, so that the abutment member 45 is slidingly connected to the connecting member 44 along the length direction of the connecting member 44, so that the position of the abutment member 45 on the connecting member 44 is adjustable, further improving the flexibility of use of the fixing component 4.

[0042] Abutment strips 21 are fixedly connected to both sides of the screen 2. The abutment strips 21 are extended along the length direction of the screen 2. The abutment strips 21 are used for abutment by the abutment member 45. On the one hand, the force-bearing area of ​​the screen 2 is increased to better fix the screen 2; on the other hand, compared with the screen 2, the abutment strips 21 are flatter, making the abutment of the abutment member 45 more stable.

[0043] The handle is equipped with a rubber cover to improve the grip comfort of the staff.

[0044] The implementation principle of Example 1 is: when screening a mixture containing NdFeB, abrasive and chamfering water, first pour the mixture onto the screen 2 poured into the screening slot 11 from the feed port 13, and start the vibration motor 3, the chamfering water and NdFeB product fall into the product slot 112 below the screen 2 and flow out from the other end of the screening slot 11, and the abrasive leaves from the other end of the screen 2.

[0045] When replacing the screen 2, the movable member 42 is rotated relative to the support seat 41. The movable member 42 drives the linkage member 43 to rotate, and the linkage member 43 drives the connecting member 44 to rotate upward, thereby driving the abutting member 45 to rotate upward, releasing the limit of the abutting member 45 on the abutting strip 21, and then releasing the limit of the abutting member 45 on the screen 2, so as to facilitate the removal of the screen 2; when installing the screen 2, place the new screen 2 on the supporting edge 12, and then rotate the movable member 42 in the opposite direction, so that the limit surface 431 of the linkage member 43 abuts against the connecting member 44 to limit the screen 2; the position of the abutting member 45 can be adjusted according to the actual limit requirements.

With this design, a connection is established between adjacent movable parts 42, which can drive all fixing components 4 to be unlocked at one time, further improving the convenience of replacing the screen 2.

[0048] Reference Figure 4 Furthermore, a first rubber pad 22 is provided on the surface of the abutment strip 21 for abutment of the abutment member 45, thereby playing a certain shock-absorbing and protective role, reducing the risk of damage to the fixed component 4 during vibration screening, and extending the service life of the fixed component 4.

[0049] Reference Figure 5 Furthermore, the limiting surface 431 is fixedly connected with a second rubber pad 432. On the one hand, it further reduces shock and protects the fixing component 4, thereby extending the service life of the fixing component 4; on the other hand, it increases the friction between the limiting surface 431 and the connecting member 44 to reduce the risk of loosening of the fixing component 4 during vibration screening.
