Description

Technical Field

[0001] This utility model belongs to the field of steel plant solid waste briquetting and recycling technology, and in particular relates to a production device for compacted steel scrap and steel slag particles into briquettes. Background Technology

[0002] In the field of steel mill solid waste briquetting and recycling, such as steel scrap and slag particles, existing technology involves mixing the materials, heating them to over 450°C in a rotary kiln, and then pressing them into cylindrical iron blocks using a hydraulic press mold. These iron blocks are then added to the converter for smelting as scrap steel. However, this process relies on a large hydraulic station, valves, and pipeline system. The system is complex, and there is a risk of hydraulic oil leakage, which could lead to flammable and explosive accidents and pollute soil and water bodies. Furthermore, the energy consumption and maintenance costs are high.

[0003] Therefore, there is an urgent need for a production device that compacts steel scrap and slag particles into briquettes to solve the above-mentioned technical problems. Utility Model Content

[0004] The purpose of this utility model is to provide a production device for compacting steel chips, steel slag particles, and steel briquettes. By using a drop hammer compaction mechanism to replace the traditional hydraulic system for compacting steel chips, steel slag particles, and other waste materials, it first achieves energy saving, and secondly eliminates the risk of hydraulic oil leakage from the hydraulic station, valves, and pipeline system, thus avoiding flammable and explosive accidents caused by oil leakage and pollution problems to soil and water bodies.

[0005] To achieve the above objectives, this utility model provides the following solution:

[0006] A production apparatus for compacting steel scrap and slag particles into briquettes includes an outer shell with a feeding mechanism connected to it. A storage mechanism is located inside the outer shell to hold the steel material entering the shell via the feeding mechanism. A discharge mechanism is located at the end of the storage mechanism furthest from the feeding mechanism. A drop hammer compaction mechanism is located inside the outer shell to compact the steel material. After compaction, the steel material is transported to the outside of the outer shell via the discharge mechanism to continue the next process.

[0007] As one specific implementation method, the feeding mechanism includes a hopper, which is fixedly connected to the outer casing of the device. The outer casing of the device is provided with a chute, which is connected to the hopper.

[0008] As one specific implementation method, the material storage mechanism includes a rotating receiving hopper, which is connected to a driving mechanism. The driving mechanism is used to drive the rotating receiving hopper to rotate so that the steel material is evenly distributed. A supporting steel plate is fixedly connected inside the outer shell of the device, which is used to support the rotating receiving hopper.

[0009] A water-cooled mold sleeve is vertically positioned below the rotating receiving hopper. After passing through the rotating receiving hopper, the steel material falls into the water-cooled mold sleeve and is processed by the drop hammer compaction mechanism to form steel blocks.

[0010] In one specific implementation, the drive mechanism includes a variable frequency motor fixedly connected to the inner wall of the device housing. The variable frequency motor is connected to a drive gear via a reducer. The drive gear meshes with a drive gear ring, which is fixedly sleeved on the outer wall of the rotating receiving hopper.

[0011] As one possible implementation, the supporting steel plate is provided with a pressure bearing, which is used to make the rotating receiving hopper rotate more smoothly.

[0012] As one specific implementation method, the drop hammer compaction mechanism includes a hoisting winch fixedly connected to the top wall inside the device housing, a steel wire rope wound on the hoisting winch, an electromagnet fixedly connected to the movable end of the steel wire rope, the electromagnet being electrically connected to the power supply winch, a mold guide rod fixedly connected to the center of the top wall inside the device housing, and a hammer block slidably sleeved on the outer wall of the mold guide rod.

[0013] As one specific implementation method, the discharge mechanism includes a pallet cart, a moving drive hydraulic cylinder, an inclined guide rail, a damper slope chute, and a conveyor belt;

[0014] The pad carriage is located below the mold guide rod. The pad carriage is fixedly connected to the inclined guide rail and the movable end of the moving drive hydraulic cylinder. The inclined guide rail is slidably connected to the damper slope groove. The pad carriage has a block iron discharge port. When the moving drive hydraulic cylinder is driven, it drives the pad carriage to slide until the block iron discharge port is aligned with the cavity formed by the mold guide rod and the water-cooled mold sleeve. After the steel block falls from the block iron discharge port, it falls onto the conveyor belt for the next process.

[0015] As a specific implementation method, the damper slope groove is provided with a number of holes and slots, and a damper is installed in each of the holes and slots.

[0016] As one specific implementation method, the side of the inclined guide rail is trapezoidal, wherein the high end of the trapezoid is close to the moving drive hydraulic cylinder.

[0017] Compared with the prior art, the present invention has the following advantages and technical effects:

[0018] This invention replaces the traditional hydraulic system with a drop hammer compaction mechanism to compact waste materials such as steel chips and slag particles, eliminating the risk of hydraulic oil leakage from hydraulic stations, valves, and pipeline systems. This avoids flammable and explosive accidents caused by oil leakage, as well as pollution problems to soil and water. At the same time, the mechanical drop hammer structure greatly simplifies the system complexity, significantly reduces energy consumption and equipment maintenance costs, and the coordinated operation of the storage and discharge mechanisms ensures the continuity and efficiency of the steel briquetting process, ultimately achieving safe, environmentally friendly, and low-cost production of solid waste briquetting iron.

[0026] 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.

[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Reference Figures 1 to 5 This utility model discloses a production device for compacting steel scrap and steel slag particles into briquettes, including a device shell 1, a feeding mechanism connected to the device shell 1, a storage mechanism inside the device shell 1 for placing steel material entering the device shell 1 through the feeding mechanism, a discharge mechanism at the end of the storage mechanism away from the feeding mechanism, and a drop hammer compaction mechanism inside the device shell 1 for compacting the steel material (including steel particles selected from steel scrap and steel slag). After the steel material is compacted, it is transported to the outside of the device shell 1 through the discharge mechanism to continue the next process.

[0029] By replacing the traditional hydraulic system with a drop hammer compaction mechanism to compact waste materials such as steel chips and slag particles, the risk of hydraulic oil leakage from hydraulic stations, valves, and pipeline systems is eliminated, avoiding flammable and explosive accidents caused by oil leakage and pollution problems to soil and water bodies. At the same time, the mechanical drop hammer structure greatly simplifies the system complexity, significantly reduces energy consumption and equipment maintenance costs, and the coordinated operation of the storage and discharge mechanisms ensures the continuity and efficiency of the steel briquetting process, ultimately achieving safe, environmentally friendly, and low-cost production of solid waste briquetting iron.

[0030] The feeding mechanism includes a hopper 2, which is fixedly connected to the outer casing 1. A chute 3 is provided inside the outer casing 1, and the chute 3 is connected to the hopper 2. The storage mechanism includes a rotating receiving hopper 8, which is driven by a drive mechanism 10. The drive mechanism 10 drives the rotating receiving hopper 8 to rotate, ensuring uniform steel material distribution. A support steel plate 21 is fixedly connected inside the outer casing 1. The support steel plate 21 supports the rotating receiving hopper 8, and a pressure bearing 11 is provided on the support steel plate 21 to ensure smoother rotation of the rotating receiving hopper 8. The drive mechanism 10 includes a variable frequency motor 1001 fixedly connected to the inner wall of the device housing 1. The variable frequency motor 1001 is connected to a drive gear 1002 through a reducer. The drive gear 1002 is meshed with a drive gear ring 1003. The drive gear ring 1003 is fixedly sleeved on the outer wall of the rotating receiving hopper 8. The device housing 1 also has a drive gear box 1004 inside. The drive gear box 1004 is fixedly connected to the support steel plate 21 through fixing bolts 1005. When the drive mechanism 10 is in use, the variable frequency motor 1001 is started, which causes the drive gear 1002 to rotate and drive the drive gear ring 1003 to rotate, thereby driving the rotating receiving hopper 8 to rotate, so that the steel material is distributed more evenly.

[0031] A water-cooled mold sleeve 12 is vertically positioned below the rotating receiving hopper 8. After passing through the rotating receiving hopper 8, the steel material falls into the water-cooled mold sleeve 12 and is processed into steel blocks by the drop hammer compaction mechanism. The specific feeding process is as follows: enclosed raw material warehouse → underground silo batching feeder → conveyor belt → rotary kiln heating and mixing → feeding hopper car lifting and feeding → insulated silo → hopper 2 → chute 3 → rotating receiving hopper 8 → annular water-cooled mold sleeve 12.

[0032] Reference Figure 1 The water-cooled mold sleeve 12 has an inlet water pipe 19 connected to the lower left side and an outlet water pipe 20 connected to the upper right side. The coolant used inside the water-cooled mold sleeve 12 is an aqueous solution, which is constantly in circulation. The circulation process is as follows: circulating water tank → pump → main inlet pipe → branch inlet pipe → inlet water pipe 19 → water-cooled mold sleeve 12 → outlet water pipe 20 → return water branch pipe → main return pipe → radiator → circulating water tank. A check valve is installed on the main inlet pipe or branch inlet pipe to prevent coolant backflow.

[0033] The drop hammer compaction mechanism includes a lifting winch 4 fixedly connected to the top wall inside the device housing 1. A steel wire rope is wound around the lifting winch 4, and an electromagnet 6 is fixedly connected to the movable end of the steel wire rope. The electromagnet 6 is electrically connected to the power supply winch 5. A mold guide rod 7 is fixedly connected to the center of the top wall inside the device housing 1, and a tamping block 9 is slidably sleeved on the outer wall of the mold guide rod 7. In use, when the electromagnet 6 is de-energized, the tamping block 9 is cast into a steel block and cooled by water-cooled steel chips within the mold sleeve 12. The annular electromagnet 6 descends via the steel wire rope of the lifting winch 4, attracting the tamping block 9 to rise to the top. When the electromagnet 6 is de-energized, the process repeats, thus compacting the steel material into a steel block.

[0034] The discharge mechanism includes a pad carriage 13, a moving drive hydraulic cylinder 14, an inclined guide rail 15, a damper slope chute 16, and a conveyor belt 17. The side of the inclined guide rail 15 is trapezoidal, with the high end of the trapezoid close to the moving drive hydraulic cylinder 14. The pad carriage 13 is located below the mold guide rod 7. During the process of the tamping hammer block 9 compacting the steel, the top surface of the pad carriage 13 contacts the bottom surface of the mold guide rod 7 and the water-cooled mold sleeve 12 to prevent the steel from overflowing. The pad carriage 13 and the inclined guide rail 17 are connected. The inclined guide rail 15 is slidably connected and fixedly connected to the movable end of the moving drive hydraulic cylinder 14. The inclined guide rail 15 is slidably connected to the damper slope groove 16. The pad carriage 13 is provided with a block iron discharge port 18. When the moving drive hydraulic cylinder 14 is driven, it drives the pad carriage 13 to slide until the block iron discharge port 18 is aligned with the cavity formed by the mold guide rod 7 and the water-cooled mold sleeve 12. After the steel block falls from the block iron discharge port 18, it falls onto the conveyor belt 17 for the next process. During use (i.e., the process of demolding and transporting the steel block after it has been compacted), the driving hydraulic cylinder 14 moves the pad carriage 13 downwards and backwards along the trapezoidal guide rail → the block iron discharge port 18 of the pad carriage 13 aligns with the lower port of the water-cooled mold sleeve 12 → the electromagnet 6 is de-energized, causing the tamping hammer block 9 to demold and fall onto the conveyor belt 17 → the annular electromagnet 6 descends via the steel wire rope of the hoisting winch 4, attracting the tamping hammer block 9 to rise to the top → the conveyor belt 17 transports the steel block to the finished product warehouse → the system and the pad carriage 13 repeat the next action. (Refer to...) Figure 3 The arrow indicates the direction of movement of the pad carriage 13. The inclined guide rail 15 is set as a trapezoid, and the pad carriage 13 can move downward and backward when it moves. In this way, the top surface of the pad carriage 13 gradually separates from the mold guide rod 7 and the water-cooled mold sleeve 12, reducing the translational resistance of the pad carriage 13 and preventing damage to the mold guide rod 7 and the water-cooled mold sleeve 12.

[0035] Reference Figure 5The damper slope groove 16 has several holes and slots, and a damper is installed in each hole and slot. The damper solves the noise pollution problem caused by the large vibration of the drop hammer rammer. The end of the damper away from the hole and slot is close to the ground. Since the contact area between each damper and the ground is small, a contact plate made of steel plate is placed between the damper and the ground to increase the contact area between the damper and the ground.
