Description

Technical Field

[0001] This utility model relates to the field of metallurgical engineering technology, and in particular to a dust removal device for a special steel smelting workshop. Background Technology

[0002] A dust removal device for special steel smelting workshops is an environmentally friendly device designed for the high-temperature, high-dust environment of special steel smelting. It comprehensively utilizes multiple dust removal technologies, including filtration, electrostatic adsorption, and wet spraying, to collect and treat waste gases containing large amounts of metal oxides, fumes, and other pollutants generated during the smelting process. This device not only effectively reduces dust concentration in the workshop, creating a safe and healthy working environment for workers, but also significantly reduces dust emissions, preventing atmospheric pollution. Furthermore, by reducing dust corrosion of equipment, it extends the service life of smelting equipment, ensuring the efficient and stable operation of special steel smelting production.

[0003] Dust removal devices in smelting workshops capture dust-laden gases generated during the smelting process using dust collection hoods. Powered by fans, the dust-laden gases are directed through ducts into dust collectors, such as bag filters which intercept dust particles, electrostatic precipitators which use a high-voltage electric field to charge and adsorb dust, and cyclone dust collectors which rely on centrifugal force to separate dust. The purified gas is then discharged through ducts by fans. A dust removal system periodically removes dust from the dust collectors, and an ash discharge device discharges the dust, thereby achieving the purpose of dust removal and purification.

[0004] However, some existing dust removal devices in special steel smelting workshops suffer from the problem of being unable to adjust the size of the discharge port, a particularly prominent defect. Due to the complex and variable working conditions in special steel smelting, the amount and characteristics of dust generated at different smelting stages vary significantly, and the dust conveying requirements also differ in subsequent processing steps. However, existing dust removal devices are limited by structural design and technical constraints, with their discharge ports often using fixed specifications or simple opening and closing mechanisms, making it difficult to flexibly adjust the discharge port size according to actual working conditions. When smelting generates a large amount of dust, a fixed-size discharge port easily leads to dust accumulation and blockage, affecting dust removal efficiency and equipment operational stability. Conversely, when dust levels are low, the inability to reduce the discharge port size results in energy waste, increased unnecessary operating costs, and impacts the coordination and continuity of subsequent material handling processes, severely hindering the high-efficiency and refined development of special steel smelting workshop production. Therefore, this paper proposes a dust removal device for special steel smelting workshops to address these issues. Utility Model Content

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, when it is necessary to adjust the size of the discharge port opening, the traction rod drives the control disc to slide along the outer wall of the discharge port. The control disc pushes the telescopic column to move the moving disc downward inside the discharge port. When the moving disc moves downward, the traction rod slides in the fixed ring, causing the baffle to move downward against the spring force. The contraction column then compresses the spring. When the moving disc moves to the appropriate position, the limiting plate contacts the inner wall at the top of the discharge port and stops moving. At this time, the telescopic column stops moving, and the baffle stabilizes in the corresponding position, thereby realizing the adjustment of the discharge port opening size. This allows for flexible control of the discharge speed and flow rate of the sludge storage bin, which facilitates the adjustment of discharge efficiency according to actual needs and improves the controllability and practicality of material discharge.

[0016] 2. In this utility model, when it is necessary to prevent the discharge hopper from clogging, the cross support rod drives the connecting column to be fixed on the inner wall of the top of the discharge hopper, providing support for the anti-clogging component. The connecting column drives the connecting shaft to rotate, and the connecting shaft drives the stirring rod to make a circular motion. The stirring rod drives the fixed rod and the stirring block to move accordingly, stirring and guiding the material in the discharge hopper. At the same time, the push rod drives the push block to move, and the push block pushes the stirring rod, causing the stirring rod to slide on the inner wall of the bottom end of the connecting column, thereby achieving the effect of preventing the discharge hopper from clogging and ensuring that the material can be discharged smoothly from the discharge hopper.

[0024] 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.

[0025] Reference Figures 1 to 3 This utility model provides an embodiment of a dust removal device for a special steel smelting workshop, comprising a base plate 1. Multiple supports 2 are fixedly connected to the top of the base plate 1. The supports 2 raise the upper structure, such as the sludge storage bin 3, to a certain height from the ground, facilitating lower material discharge operations. The sludge storage bin 3 is fixedly connected to the top of the supports 2. Two discharge bins 4 are fixedly connected to the bottom of the sludge storage bin 3, further concentrating dust and other dirt within the sludge storage bin 3 and conveying it to the discharge port 5. The bottom of each of the two discharge bins 4 is fixedly connected to a discharge port 5, which is connected to subsequent collection equipment or a transport device to ensure that the dust can be promptly removed for treatment. Two rotating shafts 6 are rotatably connected to the inner walls of the tops of the two discharge ports 5. Through the rotating shafts 6, baffles 7 can be adjusted in angle as needed, thereby controlling the opening size of the discharge ports 5.

[0026] Multiple rotating shafts 6 are each fixedly connected to a baffle 7. When the opening size of the discharge port 5 needs to be adjusted, the baffle 7 is rotated by external force, changing its position and angle within the discharge port 5. Multiple contraction columns 8 are fixedly connected to the bottom of each of the multiple baffles 7. When the angle of the baffle 7 needs to be adjusted, the contraction columns 8 will extend or retract according to the external force. Fixed rings 10 are fixedly connected to the bottom of each of the multiple contraction columns 8. The function of the fixed rings 10 is to connect the contraction columns 8 to the traction rods 11. The movement of the traction rods 11 drives the fixed rings 10 to move up and down, thereby controlling the extension and retraction of the contraction columns 8. Two traction rods 11 are fixedly connected to the inner walls of the bottom of each of the two discharge ports 5. When the extension column 13 drives the moving disc 15, the moving disc 15 pulls the traction rods 11, which in turn drive the contraction columns 8 through the fixed rings 10, thereby adjusting the angle of the baffle 7.

[0027] Control panels 12 are fixedly connected to both sides of multiple traction rods 11. The control panels 12 are fixedly connected to the traction rods 11, and operating the control panels 12 can drive the traction rods 11 to move, thereby adjusting the angle of the baffle 7. Telescopic columns 13 are fixedly connected to the bottom ends of both sides of the multiple traction rods 11. The telescopic columns 13 make the adjustment of the baffle 7 angle more automated and precise, enabling quick and accurate adjustment of the opening size of the discharge port 5 according to production needs, thus improving the working efficiency and adaptability of the dust removal device. Limiting plates 14 are fixedly connected to the outer bottom ends of the multiple telescopic columns 13. The function of the limiting plates 14 is to limit the extension and retraction range of the telescopic columns 13, preventing excessive extension or retraction that could damage the equipment. The limiting plates 14 contact the inner wall of the discharge port 5, and anti-blocking components are fixedly connected to the top interior of the two discharge bins 4 to prevent clogging.

[0028] Reference Figures 3 to 5 The anti-clogging component includes two cross-shaped support rods 16, which are externally fixedly connected to the inner top walls of the two discharge hoppers 4. Connecting columns 17 are fixedly connected to the bottom ends of the two cross-shaped support rods 16, transmitting the supporting force from the cross-shaped support rods 16 to the connecting shafts 18, stirring rods 19, and other components below, while also providing a mounting base for these components. Multiple connecting shafts 18 are rotatably connected to the bottom end of the connecting column 17. When an external power source drives the connecting column 17 or other components, the connecting shafts 18 rotate accordingly, thereby driving the stirring rods 19 to rotate. Stirring rods 19 are fixedly connected to the outside of each of the multiple connecting shafts 18. When the connecting shafts 18 rotate, the stirring rods 19 rotate accordingly. During rotation, the stirring rods 19 agitate the dust and other materials in the discharge hopper 4 that are about to enter the discharge port 5, breaking up the blockage structure formed by material accumulation and agglomeration, keeping the material loose and allowing it to pass smoothly through the discharge port 5.

[0029] Push rods 20 are fixedly connected to the bottom ends of the two connecting columns 17. The movement of the push rods 20 drives the push blocks 21 to move up and down, thereby adjusting the angle of the stirring rods 19 to better prevent clogging. Push blocks 21 are fixedly connected to the bottom ends of the two push rods 20. Fixed rods 22 are fixedly connected to the bottom ends of the multiple stirring rods 19. The stirring block 23 and the stirring rods 19 form a whole. When the stirring rods 19 rotate, the stirring block 23 can more fully stir and disperse the material, further preventing material agglomeration and clogging, and improving the working performance of the anti-clogging component. The stirring blocks 23 are fixedly connected to the bottom ends of the multiple fixed rods 22. When the stirring rods 19 drive the stirring blocks 23 to rotate, the special structure of the stirring blocks 23 can effectively break up agglomerates in the material, breaking the material into smaller particles, making the material easier to flow.

[0030] Reference Figures 1 to 3 Multiple stirring rods 19 have their top ends slidably connected to the inner wall of the bottom end of the connecting column 17. When the connecting column 17 is driven by an external power source to move or rotate, the stirring rods 19 can slide on the inner wall of the connecting column 17, cooperating with their own rotation to more fully stir and guide the material in the discharge hopper 4, effectively preventing the material from accumulating and clogging in the hopper. The outer sides of the multiple stirring rods 19 are slidably connected to the outside of the push block 21. Multiple limiting slots are located on both sides of the two discharge ports 5. When the baffle 7 rotates around the rotating shaft 6 to adjust the opening size of the discharge port 5, its edge slides in the limiting slots to prevent the baffle 7 from shifting or tilting excessively. When the traction rod 11 drives the fixed ring 10 and the contraction column 8 to move, the limiting slots also ensure the accuracy of the movement trajectory.

[0031] Multiple baffles 7 are externally slidably connected to the interior of two discharge ports 5. When it is necessary to adjust the opening size of the discharge ports 5, the baffles 7 are moved by components such as telescopic columns 13 and traction rods 11. The baffles 7 slide on the slide rail inside the discharge ports 5 and rotate around the rotating shaft 6, changing their angle and position inside the discharge ports 5. The externally slidably connected to the inner walls of multiple fixed rings 10 are multiple traction rods 11. When the telescopic column 13 drives the moving disk 15 to move, the moving disk 15 pulls the traction rods 11, which slide inside the fixed rings 10, thereby driving the fixed rings 10 to move up and down. The angle of the baffles 7 is adjusted by the retracting column 8. The bottom ends of the multiple telescopic columns 13 are respectively fixedly connected to the moving disks 15. The extension or retraction of the telescopic columns 13 drives the moving disks 15 to move up and down inside the discharge ports 5.

[0032] The movable disc 15, connected to the traction rod 11, converts the telescopic movement of the telescopic column 13 into the up-and-down movement of the traction rod 11, thereby adjusting the angle of the baffle 7. Multiple control discs 12 are slidably connected to the outside of the two discharge ports 5 on adjacent sides. Operators can manually operate the control discs 12 to slide outside the discharge ports 5, driving the traction rod 11 to move, thus adjusting the angle of the baffle 7. Multiple retractable columns 8 are each fitted with a spring 9. When the telescopic column 13 drives the traction rod 11 and the fixing ring 10 to move, the retractable column 8 will extend or retract according to the external force, at which time the spring 9 is compressed or stretched. When the external force disappears, the spring 9, relying on its own elastic restoring force, pushes the retractable column 8 back to its original position. The tops of multiple limiting discs 14 are slidably connected to the inner walls of the tops of the two discharge ports 5. The function of the limiting discs 14 is to limit the extension and retraction range of the telescopic column 13. When the telescopic column 13 extends or retracts to a certain position, the limiting discs 14 abut against the inner walls of the tops of the discharge ports 5, preventing the telescopic column 13 from continuing to move.

[0033] Multiple movable discs 15 are externally slidably connected to the interior of two discharge ports 5. When the telescopic column 13 extends or retracts, it drives the movable discs 15 to slide on the slide rails inside the discharge ports 5. The movable discs 15 transmit force through components such as the traction rod 11 and the fixing ring 10 to adjust the angle of the baffle 7. A top cover 24 is fixedly connected to the top of the sludge storage bin 3. The function of the top cover 24 is to seal the top of the sludge storage bin 3 to prevent dust and other pollutants from overflowing from the top of the sludge storage bin 3 and polluting the workshop environment. A connecting block 25 is fixedly connected to the right side of the sludge storage bin 3. The function of the connecting block 25 is to serve as a connecting component between the sludge storage bin 3 and the pipe 26, providing an installation support point for the pipe 26. A pipe 26 is fixedly connected to the bottom end of the connecting block 25. The function of the pipe 26 is to serve as a gas transmission channel, transporting dust-laden waste gas from the workshop collection point to the sludge storage bin 3 for treatment, or discharging the treated clean gas. A motor 27 is fixedly connected to the bottom right side of the pipe 26, and the bottom end of the motor 27 is fixedly connected to the top of the base plate 1. The motor 27 provides reliable power support for the dust removal device, ensuring the continuity and efficiency of the dust removal process, and is one of the core components for the normal operation of the entire dust removal device.

[0034] Working principle: When it is necessary to adjust the opening size of the discharge port 5, the operator pushes the control panel 12. The control panel 12 drives the traction rod 11 to slide along the outer wall of the discharge port 5. During the sliding process, the outer side of the traction rod 11 slides and engages with the inner wall of the fixed ring 10, causing the fixed ring 10 to move downward. The fixed ring 10 then drives the baffle 7 to overcome the elastic force of the spring 9 through the contraction column 8 and slide downward along the inner wall of the discharge port 5. At the same time, the telescopic column 13 extends and retracts with the movement of the traction rod 11, causing the moving plate 15 to move downward inside the discharge port 5 until the limiting plate 14 slides to the limiting slot on the inner wall of the top of the discharge port 5 and is limited. At this time, the baffle 7 is fixed in the corresponding position, completing the adjustment of the opening size of the discharge port 5. This achieves flexible control of the discharge speed and flow rate of the sludge storage bin 3, which can not only adapt to different material discharge requirements and avoid blockage or waste due to excessive discharge, but also slow down or stop the discharge when needed, which is convenient for equipment maintenance and material management, and significantly improves the practicality and controllability of the material discharge system.

[0035] The cross-shaped support rod 16 is fixed to the inner wall of the top of the discharge hopper 4, providing a stable support base for the entire anti-clogging assembly. The connecting column 17 is connected to and driven by the cross-shaped support rod 16, keeping the connecting column 17 in a fixed position. The connecting shaft 18 rotates inside the bottom end of the connecting column 17, driving the stirring rod 19 connected to it to perform a circular motion. The movement of the stirring rod 19, in turn, drives the fixed rod 22 and the stirring block 23 to rotate together, stirring and guiding the material in the discharge hopper 4. At the same time, the push rod 20 is connected to the connecting column 17 and moves with it. The push rod 20 drives the push block 21 to move. The push block 21 is slidably connected to the outside of the side of the stirring rod 19, thereby pushing the stirring rod 19 to slide up and down on the inner wall of the bottom end of the connecting column 17, further enhancing the stirring effect of the stirring rod 19 on the material, making it less likely for the material to accumulate and clog in the discharge hopper 4, thus achieving the effect of preventing the discharge hopper 4 from clogging, ensuring that the material can be discharged smoothly from the discharge hopper 4, reducing equipment failure and maintenance costs caused by clogging, and improving the operating efficiency and stability of the entire material discharge system.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
