Description

Technical Field

[0001] This utility model relates to the technical field of ring material processing equipment, and in particular to a ring material elevator material rejection mechanism. Background Technology

[0002] In the production and processing of ring materials, the ring material elevator is a key piece of equipment for realizing the vertical conveying of materials. After the materials are lifted to a predetermined height, they usually need to be screened and rejected immediately to ensure that the materials entering the next process meet the quality requirements.

[0003] In existing technologies, materials are typically unloaded directly from the elevator onto a fixed vibrating screen. This method is suitable for handling ideal materials with stable flow rates and low agglomeration. However, when the material flow rate increases, or when the material itself clumps or agglomerates due to humidity or shape, the material accumulates in the feed area of ​​the screen. This not only results in most of the screen area not being effectively utilized, significantly reducing screening efficiency, but the accumulated material layer also hinders the passage of qualified materials below, affecting screening accuracy. Long-term localized loads can also exacerbate screen wear and clogging. Furthermore, different materials have vastly different flowability and particle characteristics, requiring different screen tilt angles. However, the screen angles of existing material rejection mechanisms are mostly fixed and cannot be adjusted online according to changes in the material. This rigid design leads to poor equipment adaptability and makes it difficult to maintain optimal screening efficiency.

[0004] Therefore, this utility model proposes a material rejection mechanism for a ring material elevator to address the shortcomings of the prior art. Summary of the Invention

[0005] To overcome the above-mentioned defects, the embodiments of this utility model provide a material rejection mechanism for a ring material elevator, which solves the technical problems in related technologies / existing technologies, such as low screening efficiency and easy clogging of the screen due to local accumulation of material on the screen, and poor adaptability to materials with different characteristics due to the fixed screen angle.

[0006] According to one aspect, at least one embodiment of the present invention provides a material rejection mechanism for a ring material elevator, comprising: a mounting frame, a vibrating screen, a discharge pipe, a feed hopper; and a discharge mechanism and an adjustment mechanism.

[0007] The material discharge mechanism includes a servo motor, a drive bevel gear, a transmission bevel gear, and a rotating shaft. A dispersing cone and a dispersing guide vane are fixed on the rotating shaft. The adjustment mechanism includes an adjustment frame and a hydraulic rod.

[0008] Furthermore, the servo motor of the discharge mechanism drives the drive bevel gear meshing with the transmission bevel gear, which in turn drives the rotating shaft rotatably passing through the discharge pipe to rotate; the hydraulic rod of the adjustment mechanism is hinged between the mounting frame and the adjustment frame, and the adjustment frame is rotatably connected to one end of the vibrating screen. The extension and retraction of the hydraulic rod drives the adjustment frame to rise and fall to change the tilt angle of the vibrating screen.

[0009] Preferably, the discharge mechanism further includes a bearing housing, in which the first rotating shaft is rotatably housed, and the bearing housing provides radial support for the first rotating shaft.

[0010] Preferably, the discharge mechanism further includes a protective cover, which covers the outside of the drive bevel gear and the transmission bevel gear.

[0011] Preferably, the discharge mechanism further includes a dispersion hood, which is disposed at the bottom outlet of the discharge pipe.

[0012] Preferably, the dispersion cone is disposed at the top of the rotating shaft, and the dispersion guide vanes are uniformly distributed along the outer wall of the rotating shaft.

[0013] Preferably, the adjustment mechanism further includes a shock absorber, which is disposed between the vibrating screen and the adjustment frame.

[0014] Preferably, the adjustment mechanism further includes a second rotating shaft, and the hydraulic rod drives the adjustment frame to move by pushing the second rotating shaft upward.

[0015] Preferably, the adjustment mechanism further includes a support foot, which is fixed to the bottom of the vibrating screen and is used to contact the adjustment frame after the hydraulic rod retracts to provide support.

[0016] Preferably, the material rejection mechanism of the ring material elevator further includes a collection box disposed below the vibrating screen.

[0017] Preferably, the material rejection mechanism of the ring material elevator further includes a collection box II disposed at the end of the inclined path of the vibrating screen.

[0018] The beneficial effects of this utility model are as follows: 1. This utility model, by setting up a discharge mechanism, uses a servo motor to drive a rotating shaft equipped with a dispersing cone and dispersing guide vanes to rotate, forcibly disperses and evenly distributes the falling material, solving the problems of low screening efficiency and screen blockage caused by local accumulation and easy agglomeration of material on the screen in the prior art. It achieves the beneficial effect of evenly dispersing the material on the entire screen surface, thereby significantly improving screening efficiency and accuracy, and effectively reducing screen wear and blockage.

[0019] 2. This utility model, by setting an adjustment mechanism, uses the extension and retraction of a hydraulic rod to drive the adjustment frame connected to the vibrating screen to move, thereby changing the tilt angle of the vibrating screen. This solves the problem in the prior art where the screen tilt angle is fixed, making it difficult to adapt to materials with different flowability or particle size distribution, and thus failing to maintain the best screening effect. It achieves the beneficial effect of being able to adjust the screen tilt angle at any time according to changes in material characteristics, optimizing the screening path and speed, thereby broadening the applicability of the equipment and always maintaining a highly efficient screening state.

[0029] Please refer to Figure 1 and Figure 2As shown, a material rejection mechanism for a ring material elevator includes a mounting frame 6 serving as the mounting base. A vibrating screen 5 is pivotally mounted above the mounting frame 6 around one end. A first collection box 7 is located below the mounting frame 6, and a second collection box 8 is located on one side of the mounting frame 6. The material rejection mechanism also includes a feed hopper 1 located above the vibrating screen 5. A discharge pipe 4 is vertically fixedly connected below the feed hopper 1. A dispersion cover 209 is installed at the bottom outlet of the discharge pipe 4. A discharge mechanism 2 is installed inside the discharge pipe 4. The discharge mechanism 2 includes a servo motor 207 located beside the discharge pipe 4. The output end of the servo motor 207 is fixedly connected to a drive bevel gear 206. The drive bevel gear 206 meshes with a transmission bevel gear 205. Protective covers 208 are provided on the outside of the drive bevel gear 206 and the transmission bevel gear 205. A transmission bevel gear 205 is fixedly connected to a rotating shaft 202. The rotating shaft 202 is rotatably mounted via a bearing seat 201. A dispersion cone 204 for preliminary material dispersion is fixedly connected to the top of the rotating shaft 202. Multiple sets of dispersion guide vanes 203 are evenly distributed and fixedly connected to the outer wall of the rotating shaft 202 along its length. A material removal mechanism for a ring material elevator also includes an adjustment mechanism 3 for changing the tilt angle of the vibrating screen 5. The adjustment mechanism 3 includes an adjustment frame 301, which is rotatably connected to the bottom of one end of the vibrating screen 5. A shock absorber 302 is provided between the vibrating screen 5 and the adjustment frame 301. The adjustment mechanism 3 also includes a hydraulic rod 304, one end of which is hinged to a mounting frame 6, and the other end is hinged to the adjustment frame 301 via a rotating shaft 2 303. The bottom of the vibrating screen 5 is also provided with a support foot 305.

[0030] Please refer to Figures 1 to 5 The servo motor 207 of the discharge mechanism 2 is located next to the discharge pipe 4. The output end of the servo motor 207 is fixedly connected to the drive bevel gear 206. The drive bevel gear 206 meshes with the transmission bevel gear 205, thereby transmitting power to the rotating shaft 202 fixedly connected to the transmission bevel gear 205. The rotating shaft 202 rotates stably inside the discharge pipe 4 under the support of the bearing seat 201. The dispersing cone 204 at the top of the rotating shaft 202 and the dispersing guide vanes 203 on the outer wall rotate accordingly, forcibly dispersing and guiding the falling material. The protective cover 208 is installed on the outside of the bevel gear assembly to prevent scratching the dispersed material. The material is eventually discharged evenly through the dispersion cover 209 at the bottom of the discharge pipe 4. At the same time, the hydraulic rod 304 of the adjustment mechanism 3 is hinged between the mounting frame 6 and the adjustment frame 301. The adjustment frame 301 is rotatably connected to the bottom of one end of the vibrating screen 5. When the hydraulic rod 304 extends, it pushes the adjustment frame 301 upward through the rotating shaft 303, causing the vibrating screen 5 to pivot and rise, thereby changing the screening angle. The shock absorber 302 is set between the vibrating screen 5 and the adjustment frame 301 to absorb vibration. When the hydraulic rod 304 retracts, the support foot 305 fixed to the bottom of the vibrating screen 5 contacts the adjustment frame 301 to provide support.

[0031] As a preferred implementation method, refer to Figure 3 , Figure 4 and Figure 5 The rotating shaft 202 of the discharge mechanism 2 is rotatably housed in the bearing seat 201. The bearing seat 201 provides stable radial support for the rotating shaft 202. The dispersion cone 204 is fixedly installed on the top of the rotating shaft 202. Multiple sets of dispersion guide vanes 203 are evenly distributed and fixed along the outer wall of the rotating shaft 202. The protective cover 208 covers and encloses the meshing area of ​​the drive bevel gear 206 and the transmission bevel gear 205. The dispersion cover 209 is fixedly installed at the bottom outlet of the discharge pipe 4.

[0032] As another preferred implementation, refer to Figure 1 , Figure 2 and Figure 4 The shock absorber 302 of the adjustment mechanism 3 is located between the connection between the vibrating screen 5 and the adjustment frame 301. The hydraulic rod 304 drives the adjustment frame 301 to move along a predetermined trajectory by pushing the rotating shaft 303 upward, thereby adjusting the tilt angle of the vibrating screen 5. The support foot 305 is fixed to the bottom of the vibrating screen 5. When the vibrating screen 5 returns to the horizontal position, the bottom end of the support foot 305 contacts the upper surface of the adjustment frame 301.

[0033] As another preferred embodiment, refer to Figure 1 and Figure 2 Collection box 7 is located directly below the vibrating screen 5 and is used to collect materials that pass through the screen. Collection box 8 is located on one side of the mounting frame 6 and at the end of the inclined path of the vibrating screen 5. It is used to collect materials that fail to pass through the screen and slide down the screen surface.

[0034] Working principle: When using a ring material elevator's material rejection mechanism, the material from the ring material elevator first enters the feed hopper 1. Under the action of gravity, the material is conveyed downwards through the discharge pipe 4 below the feed hopper 1. When the processed ring material flow rate is large, the particle size is uneven, or agglomeration occurs, in order to ensure the screening effect, the discharge mechanism 2 starts working. The servo motor 207 inside the discharge mechanism 2 starts, and the output end of the servo motor 207 drives the drive bevel gear 206 to rotate. Since the drive bevel gear 206 and the transmission bevel gear 205 always maintain a meshing connection, the rotation of the drive bevel gear 206 will precisely drive the transmission bevel gear 205 and the rotating shaft 202 fixedly connected to the transmission bevel gear 205 to rotate together. The rotating shaft 202 is on the shaft The bearing seat 201 rotates stably inside, providing reliable radial support for the rotating shaft 202. As the rotating shaft 202 rotates, the dispersing cone 204 fixed to the top of the rotating shaft 202 performs initial centrifugal dispersion on the material falling from the top of the discharge pipe 4. Then, the dispersing guide vanes 203, fixed to the outer wall of the rotating shaft 202 and evenly distributed, perform secondary forced impact and guidance on the initially dispersed material, thus completely breaking up any agglomerated material. During the rotation of the driving bevel gear 206 and transmission bevel gear 205, the protective cover 208 isolates the bevel gear assembly from the material, preventing the material from being scratched or contaminated. The completely dispersed material exits from the dispersing cover at the bottom of the discharge pipe 4. Material 209 is evenly distributed onto the entire screen surface of the vibrating screen 5 below. The vibrating screen 5 screens the material under high-frequency vibration. Qualified ring materials smaller than the mesh size of the vibrating screen 5 pass through the screen and fall into the collection box 7 below the vibrating screen 5. Ring materials that do not meet the size requirements remain on the screen surface of the vibrating screen 5 and slide down along the inclined direction of the vibrating screen 5 into the collection box 8 on one side of the mounting frame 6. When the type of material being processed changes, such as changes in material flowability or particle size distribution, the adjusting mechanism 3 starts working to optimize the screening effect. The hydraulic rod 304 inside the adjusting mechanism 3 is activated and extended. The hydraulic rod 304 pushes upward through the rotating shaft 303, rotating at one end of the vibrating screen 5. The adjusting frame 301, which is dynamically connected, allows the vibrating screen 5 to rotate around another pivot end, thereby changing the overall tilt angle of the vibrating screen 5. During the entire operation, the shock absorber 302, which is set between the vibrating screen 5 and the adjusting frame 301, continuously absorbs the vibration generated by the vibrating screen 5, preventing the vibration from being transmitted to the adjusting frame 301 and the mounting frame 6 below, thus protecting the stability of the entire structure and the accuracy of the adjusting mechanism 3. When the adjustment is completed or the equipment stops running, the hydraulic rod 304 retracts, and the vibrating screen 5 descends with the adjusting frame 301 under the action of gravity until the support foot 305 installed at the bottom of the vibrating screen 5 contacts the upper surface of the adjusting frame 301, providing a stable static support for the vibrating screen 5.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
