Description

Technical Field

[0001] This disclosure relates to the technical field of electrode material production, and in particular to an anti-wear screening mechanism and a vibrating screening device. Background Technology

[0002] In the production of electrode materials, materials need to be screened before use. Currently, the industry typically uses direct-discharge screening devices, where materials are directly fed into the device and fall onto the screen, which can damage the screen. Therefore, screening devices such as those disclosed in Chinese patent document CN213914894U incorporate a distribution plate at the feed inlet to pre-disperse the material, reducing the impact on the screen. However, as the material passes through the distribution plate, friction generates magnetic impurities. These impurities mixed into the raw materials reduce the conductivity of the resulting electrode material, thus affecting the quality of the finished electrode. Utility Model Content

[0003] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide an anti-wear screening mechanism and vibrating screening device that can reduce wear on the material distribution disc.

[0011] In some embodiments, a plurality of connecting pieces are fixedly provided on the distributing disc; the plurality of connecting pieces are distributed at intervals along the periphery of the distributing disc and are respectively fixedly connected to the inner wall of the screening box; the discharge window is formed between two adjacent connecting pieces.

[0012] In some embodiments, the wear-resistant screening mechanism further includes a locking assembly, which includes a positioning bolt and a fastening nut. The positioning bolt passes through the material passage and is screwed to the fastening nut to lock and fix the material distribution plate and the wear-resistant liner.

[0013] In some embodiments, the wear-resistant screening mechanism further includes a sleeve assembly, which includes a bolt sleeve and a nut sleeve; the bolt sleeve is fitted over the positioning bolt, and the nut sleeve is fitted over the fastening nut; the bolt sleeve partially passes through the material passage and cooperates with the nut sleeve.

[0014] In some embodiments, there are multiple locking components, which are distributed at intervals along the periphery of the wear-resistant liner.

[0015] A vibrating screening device includes a discharge box, a vibrating frame, and an anti-wear screening mechanism according to any of the above embodiments; the discharge box is installed on the vibrating frame, and a discharge port is opened at the bottom of the discharge box; the bottom of the screening box is connected to the discharge port through the discharge box.

[0016] In some embodiments, the vibration frame includes a fixed base, a wobbling mounting frame, and a vibration driver.

[0018] Compared with the prior art, this disclosure has at least the following advantages:

[0019] The aforementioned wear-resistant screening mechanism, because the wear-resistant liner is applied to the distribution plate, ensures that the material entering from the feed inlet first acts on the wear-resistant liner.

[0027] To facilitate understanding of this disclosure, a more complete description will be given below with reference to the accompanying drawings, which illustrate preferred embodiments of the present disclosure. However, this disclosure can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure.

[0028] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0030] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0031] like Figure 1 and Figure 2 As shown, an embodiment of the wear-resistant screening mechanism 100 includes a screening hopper 110, a distribution plate 120, and a wear-resistant liner 130: the screening hopper 110 has a feeding port 1110, which is connected to the inside of the screening hopper 110, and a screen 1120 is provided inside the screening hopper 110; the distribution plate 120 is fixedly installed inside the screening hopper 110 and is located between the feeding port 1110 and the screen 1120; the distribution plate 120 has a plurality of distribution holes 1210; the wear-resistant liner 130 is laid on the distribution plate 120; the wear-resistant liner 130 has a plurality of perforations 1311, each perforation 1311 being connected to a distribution hole 1210 to form a material passage 1203; the feeding port 1110 is connected to the mesh of the screen 1120 through the material passage 1203.

[0032] It is understandable that, since the wear-resistant liner 130 is applied to the distribution plate 120, the material entering from the feed port 1110 will first act on the wear-resistant liner 130. The wear-resistant liner 130 will withstand the impact of the falling material, thereby reducing the wear caused by the material directly acting on the distribution plate 120, and thus effectively reducing the generation of magnetic foreign objects. Furthermore, since each perforation 1311 on the wear-resistant liner 130 is connected to each distribution hole 1210 on the distribution plate 120 to form a material passage 1203, the feed port 1110 is connected to the mesh of the screen 1120 through the material passage 1203, allowing the material in the buffer chamber 1102 to be dispersed and fall onto the screen 1120 for screening through the material passage 1203.

[0033] In this embodiment, the wear-resistant liner 130 can be a polypropylene liner, a polytetrafluoroethylene liner, a polyvinylidene fluoride liner, or a titanium alloy liner, etc., and is not limited here. Those skilled in the art can make other choices as needed. It is understood that polypropylene liners, polytetrafluoroethylene liners, polyvinylidene fluoride liners, or titanium alloy liners have high strength, strong wear resistance, and will not produce magnetic foreign matter after wear.

[0034] Combination Figure 2 As shown, in some embodiments, the wear-resistant liner 130 includes a protective base liner 1310 and a protective edge 1320. A buffer cavity 1102 is formed between the distribution plate 120 and the feeding port 1110. The protective base liner 1310 is located at the bottom of the buffer cavity 1102 and abuts against the distribution plate 120. A plurality of drainage holes 1311 are formed on the protective base liner 1310. The protective edge 1320 is disposed on the protective base liner 1310 and distributed along the periphery of the protective base liner 1310. The edge of the protective edge 1320 extends to the feeding port 1110, and the edge of the protective edge 1320 is disposed adjacent to the inner wall of the feeding port 1110. It is understandable that, since the protective edge 1320 is distributed along the periphery of the protective liner 1310, and the edge of the protective edge 1320 extends and is set near the inner wall of the feeding port 1110, when the material enters from the feeding port 1110, it can be blocked by the protective edge 1320, so that more material can fall into the protective liner 1310, thereby increasing the material flow of the material passage 1203 and ultimately improving the material distribution effect.

[0035] Combination Figure 1 and Figure 2As shown, in this embodiment, an overflow port 1321 is provided on the protective perimeter 1320, and a discharge window 1221 is formed on the peripheral sidewall of the buffer cavity 1102. The overflow port 1321 is connected to the discharge window 1221. It can be understood that since the overflow port 1321 on the protective perimeter 1320 is connected to the discharge window 1221 on the peripheral sidewall of the buffer cavity 1102, when material accumulates on the protective liner 1310, the material can also be quickly discharged from the buffer cavity 1102 through the overflow port 1321 and the discharge window 1221, thereby reducing the possibility of material blockage in the buffer cavity 1102.

[0036] Combination Figure 1 and Figure 2 As shown, furthermore, a plurality of connecting pieces 1220 are fixedly provided on the distribution plate 120; the plurality of connecting pieces 1220 are distributed at intervals along the periphery of the distribution plate 120 and are respectively fixedly connected to the inner wall of the screening box 110; a discharge window 1221 is formed between two adjacent connecting pieces 1220. It can be understood that, since the plurality of connecting pieces 1220 are distributed at intervals along the periphery of the distribution plate 120 and are respectively fixedly connected to the inner wall of the screening box 110, the plurality of connecting pieces 1220 can distribute the load of the distribution plate 120 onto the inner wall of the screening box 110, thereby improving the installation reliability and load capacity of the distribution plate 120. At the same time, when the material on the distribution plate 120 is exhausted, the material can be discharged in time through the discharge window 1221 to reduce weight.

[0037] Combination Figure 3 As shown, in some embodiments, the wear-resistant screening mechanism 100 further includes a locking assembly 140, which includes a positioning bolt 1410 and a fastening nut 1420. The positioning bolt 1410 passes through the material passage 1203 and is screwed to the fastening nut 1420 to lock and fix the material distribution plate 120 and the wear-resistant liner 130. It can be understood that since the positioning bolt 1410 passes through the material passage 1203 and is screwed to the fastening nut 1420, before screening, the fastening nut 1420 can be turned so that the positioning bolt 1410 and the fastening nut 1420 together lock and fix the material distribution plate 120 and the wear-resistant liner 130, thereby fixing the position of the material distribution plate 120 and the wear-resistant liner 130, and thus ensuring that the discharge hole 1311 and the material distribution hole 1210 remain in corresponding communication to ensure stable material discharge. When the wear-resistant liner 130 needs to be replaced, the positioning bolt 1410 and the fastening nut 1420 can be separated by turning the fastening nut 1420, thereby disconnecting the material distribution plate 120 from the wear-resistant liner 130, and then the wear-resistant liner 130 can be easily replaced. Specifically, the positioning bolt 1410 is a bolt, and both the positioning bolt 1410 and the fastening nut 1420 can be made of titanium alloy. Titanium alloy components have high structural strength and will not produce magnetic foreign matter after wear.

[0038] Combination Figure 3 As shown, in this embodiment, the wear-resistant screening mechanism 100 further includes a sheath assembly 150, which includes a locking bolt sleeve 1510 and a nut sleeve 1520. The locking bolt sleeve 1510 is fitted over the positioning locking bolt 1410, and the nut sleeve 1520 is fitted over the fastening nut 1420. The locking bolt sleeve 1510 partially passes through the material passage 1203 and cooperates with the nut sleeve 1520. It can be understood that because the locking bolt sleeve 1510 outside the positioning locking bolt 1410 partially passes through the material passage 1203 and cooperates with the nut sleeve 1520 outside the fastening nut 1420, the contact between the locking assembly 140 and the material passage 1203 can be reduced by the sheath assembly 150, thereby preventing the locking assembly 140 from wearing down the material passage 1203 during the assembly and disassembly process. Both the bolt sleeve 1510 and the nut sleeve 1520 can be made of polypropylene. Of course, this is not a limitation, and those skilled in the art can make other choices as needed.

[0039] Combination Figure 4 As shown, in some embodiments, there are multiple locking components 140, which are distributed at intervals along the periphery of the wear-resistant liner 130. It can be understood that because the multiple locking components 140 are distributed at intervals along the periphery of the wear-resistant liner 130, the wear-resistant liner 130 can form multiple dispersed connection points with the distribution plate 120 on its periphery. This not only allows the wear-resistant liner 130 to be more tightly connected to the distribution plate 120, but also does not interfere with the feeding of material in the middle of the wear-resistant liner 130. In this embodiment, there are three locking components 140, and the line connecting the three locking components 140 forms a triangle, which can simultaneously prevent the wear-resistant liner 130 from loosening in both the axial and radial directions. Of course, this is not a limitation, and those skilled in the art can increase the number of locking components 140 as needed.

[0040] Combination Figure 2 and Figure 5 As shown, this disclosure also provides a vibrating screening device 10 including a discharge box 200, a vibrating frame 300, and an anti-wear screening mechanism 100 of any of the above embodiments; the discharge box 200 is installed on the vibrating frame 300, and a discharge port 210 is opened at the bottom of the discharge box 200; a screening box 110 is disposed on the discharge box 200, and the bottom of the screening box 110 is connected to the discharge port 210 through the discharge box 200. It can be understood that since the discharge box 200 is installed on the vibrating frame 300, the discharge box 200 can swing under the vibration action of the vibrating frame 300, and the discharge box 200 drives the screening box 110, thereby causing the material on the screen 1120 in the screening box 110 to accelerate towards the discharge box 200 at the bottom of the screening box 110 and be quickly discharged from the discharge port 210.

[0041] Combination Figure 5As shown, in this embodiment, the vibration frame 300 includes a fixed base 310, a wobbling mounting frame 320, and a vibration driver 330. The wobbling mounting frame 320 is elastically disposed on the fixed base 310, and the discharge box 200 is partially embedded in the wobbling mounting frame 320. The vibration driver 330 is mounted on the wobbling mounting frame 320. It can be understood that since the wobbling mounting frame 320 is elastically disposed on the fixed base 310, and the discharge box 200 is partially embedded in the wobbling mounting frame 320, when the vibration driver 330 on the wobbling mounting frame 320 is activated, the wobbling mounting frame 320 can wobble relative to the fixed base 310 under the action of the vibration driver 330.

[0042] Furthermore, a plurality of compression springs 340 are provided between the fixed base 310 and the wobbling mounting frame 320. The plurality of compression springs 340 are distributed circumferentially around the discharge box 200, and the two ends of each compression spring 340 are respectively connected to the fixed base 310 and the wobbling mounting frame 320. It can be understood that, since the plurality of compression springs 340 are distributed circumferentially around the discharge box 200, by connecting the two ends of each compression spring 340 to the fixed base 310 and the wobbling mounting frame 320 respectively, the elastic force on the wobbling mounting frame 320 can be made more uniform in the circumferential direction, that is, the wobbling mounting frame 320 can wobble more smoothly.

[0043] Combination Figure 2 , Figure 3 and Figure 5 As shown, in some embodiments, for better understanding, the operation of the vibrating screen device 10 of the above embodiments is described as follows:

[0044] Material is fed into the feeding port 1110. Under the action of gravity, the material enters the buffer chamber 1102 and stays on the wear-resistant liner 130. The material falls into the screen 1120 through the material passage 1203. The vibration driver 330 is started. Under the vibration of the vibration driver 330, the material accelerates through the screen 1120 and moves to the discharge box 200 at the bottom of the screening box 110. The screened material is finally discharged quickly from the discharge port 210.

[0045] Compared with the prior art, this disclosure has at least the following advantages:

[0046] The aforementioned wear-resistant screening mechanism 100, because the wear-resistant liner 130 is laid on the distribution plate 120, ensures that the material entering from the feed port 1110 first acts on the wear-resistant liner 130. The wear-resistant liner 130 resists the impact force of the falling material, thereby reducing the wear caused by the material directly acting on the distribution plate 120, and thus effectively reducing the generation of magnetic foreign objects. Furthermore, since each perforation 1311 on the wear-resistant liner 130 is connected to each distribution hole 1210 on the distribution plate 120 to form a material passage 1203, the feed port 1110 is connected to the mesh of the screen 1120 through the material passage 1203, allowing the material in the buffer chamber 1102 to be dispersed and fall onto the screen 1120 for screening through the material passage 1203.

[0047] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
