Description

Technical Field

[0001] This utility model relates to the field of drum slag coolers, and more particularly to a drum slag cooler. Background Technology

[0002] In industries such as thermal power generation, steel smelting, and chemicals, boilers and incinerators generate large amounts of high-temperature slag during operation. Direct discharge of this slag can easily cause equipment burns and damage to pipelines, while also wasting waste heat and polluting the environment. The drum slag cooler, a key piece of slag processing equipment, primarily functions to cool, transport, and recover waste heat from high-temperature slag. The drum's rotation moves the slag within the drum, while heat exchange occurs through the drum wall or internal cooling water pipes, reducing the slag temperature from several hundred degrees Celsius to a safe transport range. This lays the foundation for subsequent slag resource utilization or harmless treatment, making it one of the core pieces of equipment in industrial production for ensuring stable component operation, reducing energy consumption, and minimizing pollution.

[0003] The structure of existing drum slag coolers typically includes a horizontal drum body, a drive unit, support rollers, a feed inlet, a discharge outlet, and supporting cooling components. Its technical principle is as follows: the drive unit drives the drum body to rotate slowly around its axis via gear or chain transmission. High-temperature slag enters the drum body through the feed inlet. During the drum's rotation, the slag tumbles with the drum body and moves along the drum wall towards the discharge outlet. The cooling components often employ a cooling water jacket installed on the outside of the drum, or cooling water pipes laid on the inner wall of the drum. Through heat exchange between the cooling water and the drum wall, the heat from the slag inside the drum is absorbed, achieving slag cooling.

[0004] When slag is discharged from the outlet of a traditional drum slag cooler, a large amount of dispersed dust is generated due to factors such as the rotational inertia of the drum, the impact force of the falling slag, and the uneven particle size. The dust diffusion range changes dynamically with the amount of slag discharged, which directly leads to the complete loss of control over the dust collection range. The vast majority of dust directly escapes into the working environment, seriously polluting the working environment and posing a significant threat to the health of on-site workers. Therefore, a drum slag cooler is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a drum-type slag cooler, which aims to improve the problem that traditional equipment generates a large amount of dust during material discharge, which is easily absorbed by surrounding workers and thus affects their health.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A drum slag cooler includes a drum slag cooler, a feed pipe fixedly connected to the top of one side of the drum slag cooler, a discharge pipe fixedly connected to the bottom of the other side of the drum slag cooler, a base fixedly connected to the bottom of the drum slag cooler, and an absorption component provided on the outer wall of the base; The absorption assembly includes a suction fan, the bottom of which is fixedly connected to the top of the base. A collection box is fixedly connected to the top of the base. A filter screen is provided on the inner wall of the collection box, and a cleaning component is provided on the outer wall of the filter screen. A conveying hose is fixedly connected to one side of the collection box, and a collection cover is fixedly connected to one end of the conveying hose. A fixing block is fixedly connected to the top of the other side of the drum slag cooler. A motor is fixedly connected to the bottom of the fixing block. A rotating shaft is fixedly connected to the output end of the motor. A transmission plate is fixedly connected to the top of the rotating shaft, and a connecting component is provided on the outer wall of the transmission plate.

[0007] As a further description of the above technical solution: The connecting assembly includes a second transmission plate, which is rotatably connected to the top of the first transmission plate, and a third transmission plate is rotatably connected to the bottom of the second transmission plate.

[0008] As a further description of the above technical solution: The transmission plate three is rotatably connected to a rotating shaft two, and the bottom end of the rotating shaft two is fixedly connected to the top of the other side of the drum slag cooler.

[0009] As a further description of the above technical solution: One side of the rotating shaft is fixedly connected to the outer wall of the collection cover, and one side of the collection box is fixedly connected to a cover plate via a hinge.

[0010] As a further description of the above technical solution: The cleaning assembly includes a rotating shaft three, one end of which is fixedly connected to one side of the filter screen, and a fixing plate is fixedly connected to the inner wall of the collection box.

[0011] As a further description of the above technical solution: The filter screen is rotatably connected to the inner wall of the fixed plate, and the other end of the rotating shaft is fixedly connected to the bevel gear.

[0012] As a further description of the above technical solution: Both sides of the inner wall of the collection box are rotatably connected to connecting shafts, and each connecting shaft is fixedly connected to a rotating wheel and a bevel gear on its outer wall.

[0013] As a further description of the above technical solution: The bevel gear 1 and bevel gear 2 on both sides mesh with each other, and the bevel gear 2 and multiple bevel gear 1 are located on one side of the suction fan input end.

[0014] This utility model has the following beneficial effects: 1. In this utility model, by setting a motor drive connection component, the collection hood can reciprocate around the rotating shaft, which solves the problem that traditional equipment will be accompanied by a large amount of dust during the material discharge process. This dust is easily absorbed by the surrounding workers, thus affecting their health. By dynamically expanding the dust collection area, the absorption efficiency of smoke and dust is improved, ensuring that harmful dust is fully absorbed into the purification components, thereby improving the working environment and enhancing the health protection effect for on-site workers.

[0015] 2. In this utility model, the filtered clean airflow blows the rotating wheel, which drives the filter screen to rotate through the bevel gear transmission mechanism. This solves the technical pain point that the filter screen is easily clogged by dust after long-term use, resulting in a decrease in suction power and the need for manual cleaning after shutdown. Through online self-cleaning, the centrifugal force generated by rotation is used to shake off the attached dust, which not only saves additional cleaning energy consumption, but also ensures that the equipment can maintain high-efficiency filtration performance for a long time, enhances the stability and long-term effectiveness of the entire device, and improves the automation level and practical value of the equipment.

[0018] 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.

[0019] Reference Figures 1-4 This utility model provides an embodiment of a drum slag cooler, comprising a drum slag cooler 1. A feed pipe 2 is fixedly connected to the top of one side of the drum slag cooler 1. The feed pipe 2 is used to continuously transport high-temperature materials from the production line into the interior of the drum slag cooler 1 for cooling. A discharge pipe 3 is fixedly connected to the bottom of the other side of the drum slag cooler 1. The discharge pipe 3 is used to discharge the fully cooled slag material. Its discharge port is the key working area for dust absorption and purification of this device. A base 4 is fixedly connected to the bottom of the drum slag cooler 1. The base 4 is welded from thickened steel plates and is used to provide stable and sturdy support for the entire drum slag cooler 1 and the absorption components at the top, ensuring the overall stability and safety of the equipment during operation. An absorption component is provided on the outer wall of the base 4. The absorption component is used to efficiently capture and purify the dust and smoke that are inevitably generated during the discharge process of the drum slag cooler 1, preventing pollution of the surrounding environment and protecting the health of the workers. The absorption assembly includes a suction fan 14, such as a high-pressure centrifugal fan, to generate strong negative pressure suction, providing the core power for dust collection throughout the assembly. The suction fan 14 is fixedly connected to the top of the base 4, and a collection box 13 is fixedly connected to the top of the base 4. This collection box 13 is used to temporarily store the sucked-in dust particles and provides a sealed space for filtration, purification, and dust removal. The inner wall of the collection box 13 is equipped with a filter screen 16, which is typically made of high-temperature resistant stainless steel or composite fiber filter media, used to physically intercept and efficiently filter the sucked-in dust-laden gas, separating dust from clean air. The outer wall of the filter screen 16 is equipped with a cleaning assembly, which is used for cleaning during equipment operation. During the process, airflow drives the filter screen 16 to achieve self-cleaning, enhancing the long-term operation of the components. A conveying hose 23 is fixedly connected to one side of the collection box 13. This conveying hose 23 is mostly a wear-resistant and high-temperature resistant corrugated pipe, used to connect the collection cover 12 and the collection box 13, forming a flexible conveying channel that can adapt to the swing of the collection cover 12. One end of the conveying hose 23 is fixedly connected to the collection cover 12, which is directly opposite the discharge port of the discharge pipe 3, forming a highly efficient dust collection area, maximizing the inclusion of scattered dust into the absorption components. A fixing block 5 is fixedly connected to the top of the other side of the drum slag cooler 1. This fixing block 5 is used to provide a stable mounting base for the motor 6 of the drive mechanism. The bottom of the fixing block 5 is fixed. A motor 6, such as a stepper motor 6 capable of precise speed and angle control, is fixedly connected to provide initial power for the reciprocating oscillation of the collection cover 12. A rotating shaft 7 is fixedly connected to the output end of the motor 6, which stably transmits the rotational motion of the motor 6 to the connecting assembly. A transmission plate 8 is fixedly connected to the top of the rotating shaft 7, and a connecting assembly is provided on the outer wall of the transmission plate 8. This connecting assembly converts the single rotational motion of the motor 6 into a wide-range reciprocating oscillation of the collection cover 12. The connecting assembly includes a second transmission plate 9, which is rotatably connected to the top of the transmission plate 8. A third transmission plate 10 is rotatably connected to the bottom of the second transmission plate 9. The transmission plate 8, in conjunction with the second transmission plate 9 and the third transmission plate 10, performs precise linkage. Through a clever linkage mechanism design, the circular motion of the motor 6 is transformed into the reciprocating swing motion of the collection hood 12, which effectively expands the dust absorption range and improves the collection efficiency. The transmission plate 3 10 is rotatably connected to the shaft 2 11. The bottom end of the shaft 2 11 is fixedly connected to the top of the other side of the drum slag cooler 1, and one side of the shaft 2 11 is fixedly connected to the outer wall of the collection hood 12. The shaft 2 11 serves as the central pivot of the swing of the collection hood 12, supporting it to perform a smooth reciprocating motion. The collection box 13 is fixedly connected to the cover plate 15 on one side by a hinge. The cover plate 15 is used to seal the collection box 13 during non-working hours and can be easily opened when it is necessary to clean the dust accumulated inside the box, which facilitates the maintenance of the equipment.

[0020] Reference Figure 4 and Figure 5The cleaning assembly includes a rotating shaft 22, which serves as the central drive shaft for the filter screen 16, transmitting rotational power to the filter screen 16 to enable its rotation. One end of the rotating shaft 22 is fixedly connected to one side of the filter screen 16. A fixing plate 17 is fixedly connected to the inner wall of the collection box 13, providing axial and radial positioning and support for the filter screen 16 and the rotating shaft 22 to ensure their concentricity and stability during rotation. The filter screen 16 is rotatably connected to the inner wall of the fixing plate 17. A bevel gear 21 is fixedly connected to the other end of the rotating shaft 22, serving as the main drive gear, receiving power from multiple bevel gears 20 and driving the rotating shaft 22 to rotate. Connecting shafts 18 are rotatably connected to both sides of the inner wall of the collection box 13, supporting the rotating wheel 19 and the bevel gears 20, allowing them to rotate freely without resistance. Each connecting shaft 18 has a [missing information - likely a design feature or design]. A rotating wheel 19 and a bevel gear 20 are fixedly connected. The rotating wheel 19 is usually made of lightweight aluminum alloy or high-strength plastic and is driven to rotate at high speed by the clean airflow drawn in by the suction fan 14. It provides the original power for the entire dust removal component without additional energy consumption, achieving the effect of energy saving and environmental protection. The bevel gears 20 on both sides rotate synchronously with the rotating wheel 19 and convert the kinetic energy of the airflow into mechanical torque through gear meshing, which is then transmitted to the second bevel gear 21. This achieves the purpose of converting the airflow energy into the rotational power of the filter screen 16. These bevel gears are usually made of heat-treated 45 steel or more wear-resistant alloy steel to ensure the reliability of long-term meshing transmission. The second bevel gear 21 and multiple bevel gears 20 are located on one side of the input end of the suction fan 14. This layout allows the filtered clean air to blow the rotating wheel 19 to rotate most effectively, thereby realizing the self-cleaning function of the filter screen 16.

[0021] Working Principle: During the absorption of dust generated by the material discharged from the drum slag cooler 1, the motor 6 is started. The output of the motor 6 drives the transmission plate 8 to rotate around the shaft 7. Subsequently, the transmission plate 9 drives the collection hood 12 on one side of the transmission plate 10 to reciprocate around the shaft 11. Then, the suction force generated by the fan 14 draws the dust through the collection hood 12 and the conveying hose 23 into the collection box 13. The filter screen 16 filters and isolates the dust, thus absorbing and purifying the dust and preventing external dust from being absorbed by surrounding workers, which could harm them. In the process of cleaning the surface of the filter screen 16, the filtered air blows the rotating wheel 19 and the bevel gear 20 to rotate. Since the bevel gear 20 meshes with the bevel gear 21, the rotation of the bevel gear 20 will drive the bevel gear 21 and the rotating shaft 22 to rotate as well, thereby pushing the filter screen 16 to rotate and throwing off the dust attached to the surface, preventing the dust from clogging the filter screen 16. After the equipment has finished running, the cover plate 15 is opened and the dust inside the collection box 13 is cleaned out, thereby achieving the purpose of dust collection and enhancing the long-term operation of the components.
