Description

Technical Field

[0001] This utility model relates to the field of scrap steel storage technology, specifically, to a scrap steel storage bin. Background Technology

[0002] In the steel industry and the recycling sector, scrap steel, as an important raw material for recycled metallurgy, directly impacts the pace of metallurgical production and the operating costs of scrap steel processing due to its storage and transfer efficiency. Scrap steel storage silos, as core transfer equipment in the scrap steel processing flow, primarily serve to centrally store scrap steel materials, prevent moisture and dust, and load materials in bulk onto transport vehicles (such as dump trucks and tank trucks). They are a crucial hub connecting the scrap steel collection end and the metallurgical user end.

[0003] In existing scrap steel storage silos, during actual operation, after the transport vehicles enter the designated loading area of ​​the silo, the opening of the unloading port and the parking position of the vehicles need to be adjusted manually. In some scenarios, manual coordination of measuring equipment (such as weighbridges) is also required to make weight estimates. The loading process involves multiple manual interventions and the operation steps are cumbersome. Utility Model Content

[0004] To overcome the above-mentioned defects, the embodiments of this utility model provide a scrap steel storage bin, which solves the technical problem of low operating efficiency caused by the cumbersome loading process after the material transport vehicles enter the bin.

[0005] According to one aspect, at least one embodiment of the present invention provides a scrap steel storage bin, comprising: The silo body is equipped with a partition that divides the interior of the silo body into a stacking area and a loading area; A material hoist, located inside the silo and above the partition, is used to transport materials from the stockpiling area to the loading area; An installation platform is provided in the loading area and located below the discharge port of the material elevator. The installation platform has a clearance opening on the side away from the partition. A rotating disk is rotatably connected to the mounting platform. A hopper is hinged to the edge of the rotating disk. The hopper can pass sequentially below the discharge port of the material elevator and the clearance opening under the rotation of the rotating disk. When the hopper is located in the clearance opening, it can tilt downward.

[0006] For example, in at least one embodiment of the present invention, a scrap steel storage bin further includes: A reset telescopic component is provided inside the hopper and located below the clearance opening. The protruding end of the reset telescopic component faces the mounting platform. The telescopic end of the reset telescopic component can extend and push the hopper to swing and reset.

[0007] For example, in a scrap steel storage bin provided by at least one embodiment of the present invention, there are several hoppers, and the several hoppers are arranged circumferentially along the rotating disk.

[0008] For example, in a scrap steel storage bin provided by at least one embodiment of the present invention, a transition chamfer is provided on the upper edge of the side wall of the clearance opening.

[0009] For example, in a scrap steel storage bin provided by at least one embodiment of the present invention, the cross-sectional width of the clearance opening is greater than the cross-sectional width of the hopper.

[0010] For example, in a scrap steel storage bin provided in at least one embodiment of the present invention, a rotation drive is provided below the mounting platform, and the rotation drive is used to drive the rotating disk to rotate.

[0011] For example, in a scrap steel storage bin provided by at least one embodiment of the present invention, a swing drive is provided below the mounting platform, and a striking swing rod is provided at the output end of the swing drive. The striking swing rod can strike the hopper located in the clearance opening under the driving action of the swing drive.

[0012] For example, in a scrap steel storage bin provided by at least one embodiment of the present invention, the material elevator, the mounting platform, the rotating disk and the hopper together form a loading unit, and the number of loading units is several, and the several loading units are arranged horizontally at intervals in the bin body.

[0013] For example, in a scrap steel storage bin provided in at least one embodiment of the present invention, the bin body has several entrances and exits communicating with the loading area, and the entrances and exits are provided with roller shutter doors.

[0014] For example, in a scrap steel storage bin provided by at least one embodiment of the present invention, a weight sensor is provided on the inner wall of the hopper. The weight sensor is electrically connected to the control system and is used to detect the weight of the scrap steel in the hopper in real time and feed it back to the control system.

[0015] The beneficial effects of the embodiments of this utility model are as follows: In this invention, the partition inside the silo divides the internal space into a stacking area and a loading area, achieving physical isolation between the temporary storage of scrap steel and the loading operation. This prevents materials from scattering into the loading area during the stacking process and interfering with the loading operation. At the same time, it prevents the transport vehicles from moving and colliding with the materials in the stacking area during loading, ensuring the stability of the overall operation.

[0016] The material hoist above the partition directly connects the stacking area and the loading area, and can continuously transport materials from the stacking area to the loading area without manual assistance. This replaces the traditional manual handling or multiple transfers by small transfer equipment, reduces manual intervention, and improves the efficiency of cross-area material transfer.

[0017] The mounting platform in the loading area is located below the material elevator discharge port, providing stable support for the rotating disc and hopper, ensuring accurate material receiving position in the hopper and preventing material spillage; the clearance opening on the side away from the partition provides a channel for hopper unloading, preventing the mounting platform from blocking the material from falling and ensuring a smooth unloading process.

[0018] The rotating disc works in conjunction with the hinged hopper, allowing the hopper to move cyclically with the rotating disc, passing through the receiving and unloading positions in sequence. The receiving, transfer, and unloading actions can be completed automatically without the need for manual adjustment of the hopper's angle or position. Attached Figure Description

[0026] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0027] In the steel industry and the field of recycled resources, scrap steel, as an important raw material for recycled metallurgy, directly affects the rhythm of metallurgical production and the operating costs of scrap steel processing due to its storage and transfer efficiency. Scrap steel storage silos, as core transfer equipment connecting scrap steel collection and metallurgical applications, primarily serve the functions of centralized temporary storage, moisture and dust prevention, and bulk loading of scrap steel into transport vehicles. Existing scrap steel storage silos require manual adjustment of the silo's unloading port opening and vehicle parking position after the transport vehicle enters the designated loading area. In some scenarios, manual coordination with metering equipment for weight estimation is also necessary. The loading process involves multiple stages of manual intervention, making the operation cumbersome and difficult to meet the demands of efficient and automated operations. Therefore, this embodiment provides a scrap steel storage silo to solve the aforementioned technical problems.

[0028] like Figure 1As shown, the scrap steel storage bin provided in this embodiment includes a bin body 1, which has an internally hollow structure to provide a closed space for scrap steel storage and loading, preventing the external environment from affecting the scrap steel material. A partition 2 is installed inside the bin body 1, with the edge of the partition 2 fixedly connected to the inner wall of the bin body 1, dividing the interior of the bin body 1 into a stacking area 11 and a loading area 12. The stacking area 11 is used for centralized temporary storage of scrap steel material awaiting transfer, while the loading area 12 is used for loading the material onto transport vehicles. The partition 2 separates the stacking and loading spaces, preventing material from scattering into the loading area 12 during stacking and interfering with the loading operation. It also prevents collisions between the material in the stacking area 11 and the material caused by vehicle movement during loading, ensuring the stability of the overall operation.

[0029] The silo 1 is also equipped with a material hoist 3, which is located above the partition 2. Its inlet end is set in the stacking area 11 and its outlet end is set in the loading area 12. The material hoist 3 can be an existing mature equipment such as a chain hoist or a bucket hoist. Through its own conveying structure, it can lift and transfer the scrap steel material temporarily stored in the stacking area 11 to the loading area 12, replacing the traditional manual handling or multiple transfers by small transfer equipment, reducing manual intervention, and realizing continuous transfer of materials from the stacking area 11 to the loading area 12, thereby improving the material transfer efficiency.

[0030] An installation platform 4 is installed in the loading area 12. The bottom of the installation platform 4 is fixedly connected to the bottom of the silo body 1, and the installation platform 4 is located directly below the discharge port of the material elevator 3, providing stable support for the subsequent installation of the rotating disc 5 and the hopper 6. A clearance opening 41 is provided on the side of the installation platform 4 away from the partition 2. The clearance opening 41 runs through the upper and lower surfaces of the installation platform 4, forming a channel for scrap steel materials to be unloaded from the hopper 6 to the material transport vehicle below. The setting of the clearance opening 41 ensures that when the hopper 6 rotates to this position, the internal materials can fall smoothly, avoiding the installation platform 4 from obstructing the unloading process and ensuring the smoothness of the unloading process.

[0031] The upper surface of the mounting platform 4 is rotatably connected to the rotating disk 5 via a rotating shaft. One end of the rotating shaft is fixedly connected to the center of the rotating disk 5, and the other end passes through the mounting platform 4 and extends to the bottom of the mounting platform 4. The edge of the rotating disk 5 is hinged to the hopper 6 via a hinge shaft, so that the hopper 6 can swing relative to the rotating disk 5 around the hinge shaft. When the rotating disk 5 rotates, it drives the hopper 6 to move around the circumference of the rotating disk 5, so that the hopper 6 passes under the discharge port of the material elevator 3 and the clearance opening 41 in sequence. When the hopper 6 moves to the discharge port of the material elevator 3, the hopper 6 maintains a horizontal receiving posture and receives the scrap steel material falling from the discharge port. When the hopper 6 moves to the clearance opening 41, the hopper 6 loses the support of the mounting platform 4 and tilts downward under its own weight and the weight of the material inside, unloading the material inside through the clearance opening 41. Through the cooperation of the rotating disk 5 and the hopper 6, the automatic cycle of material receiving, transfer and unloading is realized, without the need for manual adjustment of the position of the hopper 6 or the unloading angle, simplifying the loading operation steps and improving the loading efficiency.

[0032] Optionally, to ensure stable rotation of the rotating disk 5, a rotation drive component 51 is provided below the mounting platform 4, such as... Figure 2 As shown. The fixed end of the rotating drive component 51 is fixedly connected to the bottom of the hopper 1 or the bottom of the mounting platform 4, and its output end is connected to the rotating shaft of the rotating disk 5 through a coupling or transmission gear. The rotating drive component 51 can be a servo motor, which is connected to the rotating shaft through a reducer. It can precisely control the speed and start / stop of the rotating shaft, thereby controlling the rotation rhythm of the rotating disk 5. The rotating drive component 51 replaces manual pushing of the rotating disk 5 or the use of other unstable power sources, ensuring that the rotating disk 5 rotates at a uniform speed. This ensures that the interval between material receiving by the hopper 6 matches the feeding speed of the material elevator 3, avoiding insufficient material receiving and spillage in the hopper 6 due to excessive rotation speed of the rotating disk 5, or waiting for material to be received by the hopper 6 due to excessively slow rotation speed, which affects the efficiency of operation. At the same time, the controllability of the servo motor allows for adjustment of the rotation speed according to the material loading requirements, improving the applicability of the equipment.

[0033] Furthermore, considering that the hopper 6 will remain tilted after unloading and cannot automatically return to its material-receiving posture, a reset telescopic component 7 is installed inside the hopper body 1 and below the clearance opening 41, such as... Figure 2As shown. The fixed end of the reset telescopic component 7 is fixedly connected to the inner wall or bottom of the hopper 1, and its protruding end is set towards the mounting platform 4, and the end of the protruding end can contact the outer wall of the hopper 6; the reset telescopic component 7 can be an electric push rod or a hydraulic cylinder, and its extension stroke can be preset according to the swing angle of the hopper 6. After the hopper 6 finishes unloading, the protruding end of the reset telescopic component 7 extends, applies a thrust to the outer wall of the hopper 6, and pushes the hopper 6 to swing upward around the hinge axis until the hopper 6 returns to the horizontal receiving posture; after the hopper 6 is reset, the rotating disk 5 drives the hopper 6 away from the clearance opening 41, and then the protruding end of the reset telescopic component 7 retracts and resets to avoid interfering with the subsequent movement of the hopper 6. The hinge structure of the resetting telescopic component 7 and the hopper 6, along with the rotation rhythm of the rotating disk 5, work together to ensure that the hopper 6 can accurately reset after each unloading, ensuring the correct posture when receiving material next time. This avoids insufficient material receiving or material spillage due to the tilting of the hopper 6, forming a complete automated closed loop of "receiving, transferring, unloading, and resetting", further improving the continuity of the operation process.

[0034] Furthermore, to reduce structural interference between the hopper 6 and the relief opening 41 when the hopper 6 swings, a transition chamfer 411 is provided on the upper edge of the side wall of the relief opening 41, such as... Figure 2 As shown. The transition chamfer 411 is set along the entire circumferential edge of the relief opening 41, making the upper edge of the relief opening 41 a smooth inclined surface, rather than a right-angled edge. When the hopper 6 moves with the rotating disk 5 to the relief opening 41 and tilts downward, or swings upward to reset after unloading, the outer wall of the hopper 6 will contact the transition chamfer 411. The smooth inclined surface can reduce the frictional resistance between the hopper 6 and the edge of the relief opening 41, avoiding direct collision and jamming, reducing mechanical wear between the outer wall of the hopper 6 and the edge of the relief opening 41, and extending the service life of the equipment; at the same time, the guiding effect of the transition chamfer 411 makes the swinging action of the hopper 6 smoother, and with the uniform rotation of the rotating disk 5, it ensures that the hopper 6 moves along the preset trajectory, improving the overall stability of the operation and reducing the need for operation interruption and manual maintenance due to jamming.

[0035] Meanwhile, the cross-sectional width of the clearance opening 41 is greater than the cross-sectional width of the hopper 6. That is, the maximum width of the hopper 6 in the horizontal direction is less than the maximum width of the clearance opening 41 in the same horizontal direction, so that when the hopper 6 is located at the clearance opening 41, there is a gap between the outer wall of the hopper 6 and the inner wall of the clearance opening 41. The setting of this gap can further prevent the hopper 6 from colliding with the inner wall of the clearance opening 41 when it swings, while providing sufficient space for the material in the hopper 6 to fall, preventing scrap steel material from getting stuck between the hopper 6 and the opening sidewall due to insufficient width of the clearance opening 41, ensuring thorough unloading. In addition, the existence of the gap reduces the assembly accuracy requirements of the hopper 6 and the mounting platform 4, eliminating the need to strictly control the alignment position of the hopper 6 and the clearance opening 41, simplifying the processing and installation process, and reducing production costs. With the use of the transition chamfer 411, the smoothness of the hopper 6 swinging and unloading can be further improved.

[0036] Optionally, to ensure thorough unloading of the hopper 6 and prevent scrap steel from adhering to the inner wall of the hopper 6 due to gravity or friction, a swing drive 8 is installed below the mounting platform 4. The output end of the swing drive 8 is equipped with a striking swing arm 81, such as... Figure 3 As shown. The fixed end of the swing drive 8 is fixedly connected to the bottom of the mounting platform 4 or the inner wall of the hopper 1, and its output end is fixedly connected to one end of the striking swing arm 81 through a connecting rod. The other end of the striking swing arm 81 extends to the bottom of the clearance opening 41. The swing drive 8 can be a swing cylinder or a hydraulic motor, which can drive the striking swing arm 81 to swing back and forth around the output end. When the hopper 6 moves to the clearance opening 41 and tilts downward to unload, the swing drive 8 drives the striking swing arm 81 to swing upward. The end of the striking swing arm 81 hits the outer wall of the hopper 6. The vibration generated by the impact is transmitted to the inner wall of the hopper 6, causing the scrap steel material adhering to the wall to detach and be discharged with the mainstream material. After unloading, the swing drive 8 drives the striking swing arm 81 to reset downward to avoid interfering with the subsequent movement of the hopper 6. The combination of the striking arm 81 and the swing drive 8, along with the inclined unloading structure of the hopper 6, can forcibly remove material residue, ensuring the effective volume of the hopper 6 and preventing insufficient material intake for the next batch due to residual material. At the same time, vibration unloading eliminates the need for manual cleaning of the inner wall of the hopper 6, reducing manual intervention, further simplifying the operation process, and improving material utilization.

[0037] Furthermore, to enhance the equipment's processing capacity and accommodate the simultaneous loading needs of multiple material transport vehicles, the material elevator 3, mounting platform 4, rotating disc 5, and hopper 6 together form a loading unit. Several loading units are arranged at intervals along the horizontal direction of the silo body 1, such as... Figure 1As shown. The material hoist 3 of each loading unit is set at the feeding end of the stacking area 11, and can simultaneously obtain materials from the stacking area 11. The mounting platform 4, rotating disk 5 and hopper 6 of each loading unit are set in the loading area 12, and an independent unloading area is formed below the clearance opening 41 of each loading unit for one transport vehicle to park. The setting of multiple loading units allows the loading area 12 to accommodate multiple transport vehicles to load materials in parallel at the same time, avoiding the queuing of other vehicles when one vehicle is loading materials, and significantly increasing the loading volume per unit time. At the same time, each loading unit is independent of each other, and some loading units can be started and stopped flexibly according to the number of transport vehicles, without all units needing to run continuously, reducing equipment energy consumption. The stacking area 11 provides centralized material supply for all loading units, eliminating the need to set up a separate stacking space for each loading unit, saving internal space of the silo 1 and simplifying the overall structural design.

[0038] Furthermore, to facilitate the entry and exit of material transport vehicles into and out of the loading area 12, and to protect the materials within the loading area 12 from external environmental influences, the silo body 1 is equipped with several entrances and exits 13, which are connected to the loading area 12, such as... Figure 1 As shown. Each entrance / exit 13 corresponds to the unloading area of ​​a loading unit, allowing vehicles to directly enter the designated unloading area through the corresponding entrance / exit 13. This prevents vehicles from moving arbitrarily within the loading area 12 and colliding with the equipment structure, thus improving operational safety. Each entrance / exit 13 is equipped with a roller shutter door 14. The top of the roller shutter door 14 is fixedly connected to the side wall of the silo 1. The roller shutter door 14 can be driven by a motor to move up and down along the side wall of the silo 1, thus opening and closing the entrance / exit 13. When a transport vehicle needs to enter the loading area 12, the roller shutter door 14 corresponding to the entrance / exit 13 opens upward to provide a passage for the vehicle. After the vehicle enters the designated unloading area, the roller shutter door 14 closes downward to isolate external dust and rainwater from the loading area 12, preventing the scrap steel material in the loading area 12 from getting damp or contaminated, and ensuring material quality. After loading is completed, the roller shutter door 14 opens upward again, and the vehicle drives out. In non-operational states, all roller shutter doors 14 of the entrance / exit 13 are closed, keeping the silo 1 in a closed state, further protecting the internal materials and equipment. The cooperation between the roller shutter door 14 and the entrance / exit 13, combined with the independent operation of the loading unit, enables vehicles to enter and exit and loading operations to proceed in an orderly manner, while also taking into account material protection and operational convenience.

[0039] Optionally, to achieve precise control of the loading amount and avoid errors caused by manual weight estimation, a weight sensor is installed on the inner wall of the hopper 6, and the weight sensor is electrically connected to the control system. The weight sensor can be a pressure sensor, with its detection end fixedly connected to the inner wall of the hopper 6. It can detect the pressure generated by the weight of the material on the inner wall of the hopper 6 in real time and convert the pressure signal into a weight signal, which is then transmitted to the control system. The control system can be a PLC controller, with a preset maximum material receiving weight threshold for the hopper 6. When the hopper 6 moves to the discharge port of the material elevator 3 to receive material, the weight sensor feeds back the detected weight data to the control system in real time. When the weight reaches the preset threshold, the control system sends a signal to the material elevator 3 to stop feeding, preventing the hopper 6 from overloading and causing material spillage or equipment damage. After the hopper 6 has finished unloading, the weight sensor detects that the weight of the hopper 6 has returned to the empty state and feeds back a signal to the control system. The control system then controls the material elevator 3 to restart feeding and enter the next material receiving cycle. The coordination between the weight sensor and the control system, combined with the cyclical operation of the rotating disc 5, ensures that the amount of material received by the hopper 6 remains consistent each time. This ensures accurate loading of the material transport vehicle and avoids the need for the vehicle to reload due to insufficient loading, or overloading that violates traffic rules and causes safety risks. At the same time, real-time feedback of weight data helps the control system optimize the matching relationship between the rotation speed of the rotating disc 5 and the feeding speed of the material elevator 3, further improving operational efficiency and accuracy.

[0040] The overall working process of this embodiment is described in detail below with reference to the accompanying drawings: In the steel industry or recycling scenarios, the collected scrap steel is temporarily stored in the stacking area 11 of the silo 1. When it is necessary to load the transport vehicle, the transport vehicle drives to the corresponding entrance 13 of the silo 1, and the control system controls the roller shutter door 14 of the entrance 13 to open upward. The vehicle enters the unloading area of ​​the corresponding loading unit in the loading area 12 through the entrance 13. After the vehicle is parked, the roller shutter door 14 closes downward.

[0041] The rotating drive unit 51 is activated, which drives the rotating disk 5 to rotate at a constant speed on the mounting platform 4 via the rotating shaft. The rotating disk 5 drives the hopper 6 to move circumferentially. When the hopper 6 moves below the discharge port of the material elevator 3, the control system controls the material elevator 3 to start. The feeding end of the material elevator 3 grabs scrap steel material from the stockpile area 11, lifts the material through its own conveying structure, and discharges it from the discharge port. The hopper 6 receives the discharged material. At this time, the weight sensor on the inner wall of the hopper 6 detects the weight of the material in real time and feeds the data back to the control system. When the weight reaches a preset threshold, the control system controls the material elevator 3 to stop feeding.

[0042] The rotating disk 5 continues to move the hopper 6, which is filled with material, toward the clearance opening 41. When the hopper 6 reaches the clearance opening 41, it loses the support of the mounting platform 4 and tilts downward under its own weight and the weight of the material. The material is then unloaded through the clearance opening 41 into the transport vehicle below. During this process, the control system activates the swing drive 8, which drives the striking swing arm 81 to swing upward. The end of the striking swing arm 81 strikes the outer wall of the hopper 6, and the resulting vibration causes the material adhering to the inner wall of the hopper 6 to fall off, ensuring thorough unloading.

[0043] After unloading is completed, the control system controls the extension end of the reset telescopic component 7 to extend, pushing the hopper 6 to swing upward around the hinge axis to complete the reset; after the hopper 6 is reset, the rotating disk 5 drives the hopper 6 to leave the clearance opening 41, and then the extension end of the reset telescopic component 7 retracts and resets, and the hopper 6 continues to move with the rotating disk 5, waiting to reach the material elevator 3 discharge port to receive material next time.

[0044] Once the material transport vehicle has finished loading, the control system controls the corresponding roller shutter door 14 to open upwards, allowing the vehicle to exit the loading area 12, and the roller shutter door 14 to close. If there are multiple loading units, each loading unit can execute the above process synchronously, enabling multiple vehicles to load materials in parallel. In non-operational states, all roller shutter doors 14 at entrances and exits 13 are closed, the silo 1 remains sealed, and the materials in the stockpiling area 11 and the equipment in the loading area 12 are protected.

[0045] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. 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.
