Description

Technical Field

[0001] This utility model relates to an anti-clogging shearing type protective slag grading and screening device. Background Technology

[0002] In industrial production processes such as steel smelting, protective slag is a key auxiliary material. The uniformity of its particle size directly affects the smelting effect and product quality. Therefore, it is necessary to accurately classify the protective slag raw materials through a grading and screening device. Currently, the widely used protective slag grading and screening equipment in the industry mostly uses a rotary grading screen cylinder as the core working component. It utilizes the screen hole structure with different aperture sizes on the screen cylinder wall to achieve the separation and grading of protective slag materials with different particle sizes through the rotation of the screen cylinder.

[0003] However, existing grading and screening devices have significant technical defects in practical applications. Due to the inherent characteristics of the protective slag material, such as agglomeration, strong viscosity, or uneven particle size distribution, some material easily gets stuck in the screen holes of the screening cylinder during the screening process, causing continuous blockage. As the blockage intensifies, the effective screening area of ​​the screening cylinder gradually decreases, leading not only to a significant drop in screening efficiency but also affecting the grading accuracy, failing to meet the processing requirements of classifying protective slag according to specifications. In view of this, this utility model proposes an anti-blocking shear-type protective slag grading and screening device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an anti-clogging shear-type protective slag grading and screening device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A clog-resistant shear-type protective slag grading and screening device includes a frame, wherein the frame is equipped with a rotatable grading and screening cylinder; The frame also includes two sets of mounting rods, and the grading and screening cylinder is disposed between the two sets of mounting rods. The mounting rods are arranged along the long side of the grading and screening cylinder, and multiple sets of mounting plates are evenly arranged on the mounting rods. The mounting plates are provided with elastic shearing components, and the elastic shearing components contact the protective slag raw material on the grading and screening cylinder for shearing.

[0006] As an improvement to the above technical solution, the mounting rod is provided with multiple sets of mounting holes, the multiple sets of mounting holes are matched with multiple sets of mounting plates, and the multiple sets of mounting plates are respectively set at the positions of the multiple sets of mounting holes.

[0007] As an improvement to the above technical solution, the mounting hole group includes four sets of first connecting holes, and the mounting plate is provided with four sets of second connecting holes. The four sets of first connecting holes and the four sets of second connecting holes are matched in position, and the first connecting holes and the second connecting holes are connected by bolts.

[0008] As an improvement to the above technical solution, the elastic shearing assembly includes a shearing blade, which is fixedly connected to the mounting plate; There is a gap between the shearing blade and the grading screening cylinder, and the gap is between 0.5cm and 1cm.

[0009] As an improvement to the above technical solution, the elastic shear assembly further includes two sets of fixing plates, which are symmetrically arranged on the mounting plate. An elastic rod is provided on the fixed plate, and an elastic ball is provided on the elastic rod. The elastic ball is in contact with the surface of the grading and screening cylinder.

[0010] As an improvement to the above technical solution, a reinforcing plate is provided on the fixing plate, and a through screw is provided on the reinforcing plate; Nuts are provided on the front and rear sides of the reinforcing plate. The nuts are threaded onto the outer wall of the screw. The nuts contact the front and rear surfaces of the reinforcing plate to position the screw on the reinforcing plate. The elastic rod is provided on the end face of the screw.

[0011] As an improvement to the above technical solution, the fixing plate is provided with two sets of fixing holes, and the four sets of fixing holes are matched with the four sets of second connecting holes. The fixing hole, the first connecting hole, and the second connecting hole are connected by bolts.

[0012] Compared with the prior art, the beneficial effects of this utility model are: The rotating grading and screening cylinder, supported by a frame, utilizes the rotation of the cylinder and the different aperture structures on its wall to precisely classify and screen the protective slag material by particle size, effectively meeting the processing requirements for slag classification according to specifications. Simultaneously, relying on two sets of mounting rods along the long side of the grading and screening cylinder on the frame, and multiple sets of mounting plates evenly distributed on these rods, which support elastic shearing components, when protective slag material becomes stuck in the screen apertures during the rotation of the grading and screening cylinder, the rotating cylinder can actively bring the stuck material into contact with the elastic shearing components. The elastic shearing components then shear and crush the stuck material, fundamentally preventing the reduction in screening efficiency caused by screen aperture blockage. This allows for simultaneous grading and screening operations and anti-blocking operations, enabling anti-blocking operations to be completed without stopping the machine, significantly improving the continuity and stability of protective slag screening processing. By designing the mounting rods along the long side of the grading screening cylinder and evenly distributing the mounting plates on the mounting rods, the elastic shearing components can achieve full coverage along the axial length of the grading screening cylinder. This ensures that during the rotation of the grading screening cylinder, any material stuck in the cylinder wall at any axial position can contact the elastic shearing components and be sheared, avoiding local blockages caused by blind spots in the anti-blocking area. Furthermore, the dynamic interaction between the elastic shearing components and the grading screening cylinder relies on the rotational power of the grading screening cylinder itself to drive the anti-blocking action, eliminating the need for an additional drive mechanism. This simplifies the device structure, reduces energy consumption, and ensures the timeliness and reliability of the anti-blocking operation, reducing maintenance costs and downtime losses caused by equipment blockage.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example: like Figure 1-6 As shown, this embodiment proposes an anti-clogging shear-type protective slag grading and screening device, including a frame 10, wherein the frame 10 is provided with a rotatable grading and screening cylinder 20; The frame 10 also includes two sets of mounting rods 11. The grading and screening cylinder 20 is disposed between the two sets of mounting rods 11. The mounting rods 11 are arranged along the long side of the grading and screening cylinder 20. Multiple sets of mounting plates 30 are evenly arranged on the mounting rods 11. Elastic shearing components 40 are provided on the mounting plates 30. The elastic shearing components 40 contact the protective slag raw material on the grading and screening cylinder 20 for shearing.

[0017] In this embodiment, when the grading screening cylinder 20 screens the protective slag, the grading screening cylinder 20 rotates and screens the protective slag through different apertures. During the rotation of the grading screening cylinder 20, if any protective slag gets stuck in the aperture of the grading screening cylinder 20, the rotating grading screening cylinder 20 will cause the protective slag to come into contact with the elastic shearing component 40. The elastic shearing component 40 will shear the protective slag on the grading screening cylinder 20 to avoid blockage inside the grading screening cylinder 20. The frame 10 supports a rotatable grading and screening cylinder 20. Utilizing the rotation of the grading and screening cylinder 20 and the different aperture structures on its wall, precise particle size classification and screening of the protective slag material can be achieved, effectively meeting the processing requirements for protective slag classification by specifications. Simultaneously, relying on two sets of mounting rods 11 arranged along the long side of the grading and screening cylinder 20 on the frame 10, and multiple sets of mounting plates 30 evenly distributed on the mounting rods 11, which are equipped with elastic shearing components 40, when protective slag material gets stuck in its screen holes during the rotation of the grading and screening cylinder 20, the rotating grading and screening cylinder 20 can actively bring the stuck protective slag material into contact with the elastic shearing components 40. The elastic shearing components 40 then shear and crush the stuck material, fundamentally preventing the reduction in screening efficiency caused by screen hole blockage in the grading and screening cylinder 20. This allows for simultaneous grading and screening operations and anti-blocking operations, enabling anti-blocking operations to be completed without stopping the machine, significantly improving the continuity and stability of protective slag screening processing. By designing the mounting rods 11 along the long side of the grading screening cylinder 20 and evenly distributing the mounting plates 30 on the mounting rods 11, the elastic shearing components 40 can form a full-coverage distribution along the axial length of the grading screening cylinder 20. This ensures that during the rotation of the grading screening cylinder 20, any material stuck in the cylinder wall at any axial position can contact the elastic shearing components 40 and be sheared, avoiding local blockages caused by blind spots in the anti-blocking area. Furthermore, the dynamic cooperation between the elastic shearing components 40 and the grading screening cylinder 20 relies on the rotational power of the grading screening cylinder 20 itself to drive the anti-blocking action, eliminating the need for an additional drive mechanism. This simplifies the device structure, reduces energy consumption, and ensures the timeliness and reliability of the anti-blocking operation, reducing maintenance costs and downtime losses caused by equipment blockage.

[0018] Specifically, the mounting rod 11 is provided with multiple sets of mounting holes, the multiple sets of mounting holes are matched with multiple sets of mounting plates 30, and the multiple sets of mounting plates 30 are respectively arranged at the positions of the multiple sets of mounting holes.

[0019] In this embodiment, by setting multiple sets of mounting holes on the mounting rod 11 that match the position of the mounting plate 30, each set of mounting plates 30 can be accurately positioned and installed based on the preset mounting hole positions. This effectively avoids axial or radial offset during the assembly of the mounting plates 30, ensuring that the elastic shearing component 40 mounted on the mounting plate 30 can always maintain the preset matching position with the grading screening cylinder 20. This prevents the elastic shearing component 40 from failing to effectively contact the hole-blocking protective slag due to misalignment of the mounting plate 30, thereby ensuring the stable performance of the anti-blocking shearing function and avoiding the risk of screening blockage or abnormal wear of equipment components caused by assembly errors.

[0020] Specifically, the mounting hole group includes four sets of first connecting holes 12, and the mounting plate 30 is provided with four sets of second connecting holes 31. The four sets of first connecting holes 12 and the four sets of second connecting holes 31 are matched in position, and the first connecting holes 12 and the second connecting holes 31 are connected by bolts.

[0021] In this embodiment, the mounting hole group adopts a design with four sets of first connecting holes 12 and four sets of second connecting holes 31 corresponding to the mounting plate 30. This can form a multi-point, symmetrical fixing structure at the connection interface between the mounting plate 30 and the mounting rod 11, which can make the mounting plate 30 fit more tightly with the mounting rod 11, prevent the mounting plate 30 from warping or shifting during equipment operation, and ensure that the elastic shearing component 40 always maintains the preset matching state with the grading screening cylinder 20. This ensures the continuous and stable performance of the anti-blocking shearing function and avoids screening blockage or component damage caused by failure of the connection structure.

[0022] Specifically, the elastic shearing assembly 40 includes a shearing blade 41, which is fixedly connected to the mounting plate 30; There is a gap between the shearing blade 41 and the grading screening cylinder 20, and the gap is between 0.5cm and 1cm.

[0023] In this embodiment, by fixing the shearing blade 41 to the mounting plate 30, when the shearing blade 41 contacts the protective slag in the hole and generates a shearing reaction force, such as when shearing sticky or blocky protective slag, the blade displacement, loosening or wobble is avoided, and the blade is ensured to always maintain the preset shearing posture and action direction. Meanwhile, the fixed connection structure can stably transfer the load generated during the shearing process to the mounting plate 30 and the mounting rod 11, disperse the local force, prevent the shearing blade 41 from deforming or breaking due to uneven force, ensure the structural integrity of the blade for long-term use, and thus ensure the continuous and effective shearing effect on the slag protection of the hole, avoiding the risk of failure of the anti-clogging function due to the loosening of the blade. The fixed connection method ensures that the distance between all shear blades 41 and the grading and screening cylinder 20 can be maintained within a preset range of 0.5cm-1cm for a long time. This avoids the distance fluctuation caused by loose blades and ensures that the multiple sets of shear blades 41 distributed along the axial direction of the grading and screening cylinder 20 can form a uniform shearing effect. This prevents some areas from failing to prevent clogging due to excessive spacing and some areas from experiencing equipment wear due to insufficient spacing. This consistent design can ensure that the screen holes throughout the entire length of the grading and screening cylinder 20 can be effectively protected against clogging, reduce the decrease in screening efficiency caused by local blockage, and thus improve the overall continuity and stability of the protective slag grading and screening operation.

[0024] Specifically, the elastic shear assembly 40 also includes two sets of fixing plates 42, which are symmetrically arranged on the mounting plate 30. An elastic rod 46 is provided on the fixed plate 42, and an elastic ball 47 is provided on the elastic rod 46. The elastic ball 47 is in contact with the surface of the grading and screening cylinder 20.

[0025] In this embodiment, when the elastic ball 47 contacts the surface of the rotating grading screen cylinder 20, the elastic deformation recovery force of the elastic ball 47 interacts with the rotational friction force of the grading screen cylinder 20, which can transmit continuous flexible vibration to the grading screen cylinder 20. On the one hand, the vibration can act on the protective slag material stuck in the screen hole, so that the agglomeration force between the material particles is destroyed and the adhesion force between the material and the screen hole wall is reduced. The auxiliary shearing blade 41 can more easily shear and break the stuck material. In particular, the residual material at the edge of the screen hole that the shearing blade 41 cannot fully contact can be loosened and removed by vibration, avoiding the problem of residual material after shearing and secondary accumulation and blockage.

[0026] Specifically, a reinforcing plate 43 is provided on the fixing plate 42, and a through screw 44 is provided on the reinforcing plate 43; Nuts 45 are provided on the front and rear sides of the reinforcing plate 43. The nuts 45 are threaded onto the outer wall of the screw 44. The nuts 45 contact the front and rear surfaces of the reinforcing plate 43 to position the screw 44 on the reinforcing plate 43. The elastic rod 46 is provided on the end face of the screw 44.

[0027] In this embodiment, by providing a reinforcing plate 43 on the fixed plate 42, the structural strength and rigidity of the fixed plate 42 can be significantly improved, effectively dispersing the radial reaction force generated when the elastic rod 46, the elastic ball 47 and the grading screening cylinder 20 come into contact, and preventing the fixed plate 42 from bending, deforming or loosening its connection with the mounting plate 30 due to local overload. Meanwhile, the reinforcing plate 43 provides a stable mounting reference surface for the screw 44, preventing the screw 44 from tilting or shifting during the force process, ensuring that the elastic rod 46 can transmit force in the preset radial direction, ensuring stable contact between the elastic ball 47 and the grading screening cylinder 20, avoiding the failure of the elastic component due to the deformation of the fixing plate 42, and thus maintaining the overall reliability of the shearing, elastic cleaning and anti-clogging system.

[0028] Specifically, the fixing plate 42 is provided with two sets of fixing holes 48, and the four sets of fixing holes 48 are matched with the four sets of second connecting holes 31. The fixing hole 48, the first connecting hole 12, and the second connecting hole 31 are connected by bolts.

[0029] In this embodiment, by matching the positions of four sets of fixing holes 48 with four sets of second connecting holes 31 and first connecting holes 12, and relying on the same bolt to pass through the three to achieve fastening, a multi-point fixing structure that is evenly distributed along the axial and radial directions can be formed at the connection interface of the three.
