The cyclone type waste gas dedusting equipment for steel smelting is used for supporting and fixing a dedusting barrel. An inlet valve is communicated with the dedusting barrel at an inclined angle. Waste gas enters the interior of the dedusting barrel from the inlet valve. Dust-containing gas enters the barrel body of the dedusting barrel tangentially to form a cyclone. Dust is deposited on the wall of the barrel body by centrifugal force. The dust slides along the inner wall of the dedusting barrel to the bottom of the barrel body. Clean gas flow converges to the center and is discharged from an exhaust device. Dust is discharged after being collected at the bottom, so that gas and dust are separated. Dust accumulated at the bottom of the dedusting barrel is discharged in a timely manner through a discharging device, and the dedusting operation is continuously completed.

Description

Technical Field

[0001] This invention relates to the field of waste gas dust removal technology, specifically a cyclone waste gas dust removal device for iron and steel smelting. Background Technology

[0002] Iron and steel smelting dust has properties related to its source. It is generally dust emitted into the air during the crushing, screening, and conveying of materials. Its chemical composition, true density, and other physical properties are similar to those of the original materials. The particles are relatively coarse, with large particles reaching hundreds of micrometers. Furnace dust is solid particulate matter formed by the condensation or oxidation of sublimation products or vapors produced by physical and chemical processes during metal smelting or heating. Examples include oxygen converter dust, oxygen blowing open-hearth furnace dust, and electric furnace dust. It is mainly composed of metal oxides with very fine particles, and most of it is emitted through chimneys with high-temperature flue gas.

[0003] Existing cyclone dust collectors for steel smelting are unable to capture fine dust particles during operation, resulting in low capture efficiency. Airflow disturbances can easily cause fluctuations in local dust collection efficiency. Dust can easily accumulate inside the equipment, causing wear and tear on components. Changes in operating wind pressure can affect the stable dust collection effect. Overall, the purification capacity for ultrafine exhaust gas pollutants is weak. Therefore, a new design was developed to address these issues. Summary of the Invention

[0009] A hole groove is provided on the outer edge of the conical plate, and a buffer mechanism is fixedly connected to the top of the conical plate near the hole groove. A connecting end is fixedly connected to the top of the unloading base at the position corresponding to the hole groove.

[0010] A tripod is fixedly connected to the outside of the electric push rod near the inside of the cylindrical conical plate. A reverse conical plate is fixedly connected to the bottom of the conical plate. A rubber block is fixedly connected to the bottom of the conical plate near the circumference.

[0011] The buffer mechanism includes a buffer housing, a first spring is fixedly connected to the inner wall of the buffer housing, a buffer plate is fixedly connected to the other side of the outside of the first spring, the outer side of the buffer plate is slidably connected to the inner wall of the buffer housing, and a beveled groove is opened at the bottom of the inner wall of the buffer housing.

[0012] The protective mechanism includes a protective shell, a protective support rod slidably connected to the inner wall of the protective shell, a protective base plate fixedly connected to the bottom of the protective support rod, a second spring sleeved on the outside of the protective support rod near the inside of the protective shell, and an annular block fixedly connected to the top of the protective base plate at a position corresponding to the guide tube slot.

[0013] This invention provides a cyclone-type exhaust gas dust removal device for iron and steel smelting. It has the following beneficial effects: I. This cyclone dust collector for steel smelting uses a fixed frame to support the electric push rod. The discharge trough serves to discharge exhaust gas and dust. The conical plate adopts a conical shell structure to reduce the surface pressure of the components and ensure the normal operation of the equipment. The electric push rod controls the conical plate to move up and down inside the dust collector. The bottom of the conical plate fits against the discharge base to achieve sealing or dust discharge. During equipment operation, the bottom of the barrel must be sealed to prevent affecting the airflow rotation and avoid affecting the separation of exhaust gas.

[0014] II. The cyclone dust removal equipment for steel smelting has corresponding slots and grooves on the plate and the connecting end. When the conical plate is raised and lowered by the electric push rod, the conical plate makes the slots and grooves on the plate and the connecting end fit together, thereby achieving a certain positioning effect, avoiding the displacement of the parts and grooves, ensuring the sealing between the parts, and at the same time, the buffer mechanism contacts the connecting end, thereby playing a role in shock absorption and buffering, reducing the wear of the parts.

[0015] III. In this cyclone dust removal equipment for steel smelting, a tripod supports the conical plate to maintain the stability of the components, prevent impurities from causing component displacement, and avoid affecting the operating effect of the components. The reverse conical plate seals and blocks the bottom of the conical plate, reducing the entry of impurities and preventing impurities from remaining on the inner wall of the components. Secondly, when the reverse conical plate is pressed and adhered to the discharge chute along with the conical plate, the reverse conical plate squeezes and moves impurities, avoiding affecting the adhesion between components. Furthermore, it reduces the pressure on the components and improves the stability of the components during operation. The rubber block adheres to the discharge base along with the conical plate and deforms through compression. The rubber block adheres to the discharge base, thereby improving the sealing between components, reducing wear between components, and extending the service life of the components. The guide pipe is used to guide the flow of dust, facilitating dust collection and treatment.

[0016] IV. In this cyclone-type exhaust gas dust removal equipment for steel smelting, when the conical plate is pressed against the connecting end, the top of the connecting end enters the interior of the buffer housing. The connecting end presses against the buffer plate, and the buffer plate presses against the first spring to shrink, thereby playing a role in shock absorption and buffering, avoiding hard impact damage to the components. At the same time, the fit and seal are tighter, reducing air leakage from gaps. The oblique cut groove guides the flow of impurities and prevents impurities from entering the pipe. The first spring rebounds and pushes the buffer plate to slide, pushing the impurities out.

[0017] V. In this cyclone dust removal equipment for steel smelting, when impurities fall downwards from the discharge trough, dust flows from inside the guide pipe and accumulates on the annular block. As the weight of the accumulated dust increases, the pressure causes the protective support rod to compress and contract the second spring, causing the annular block to move outwards towards the guide pipe, creating extra space in the components to facilitate the outward flow of dust. After the dust is discharged, the weight on the annular block decreases, and the second spring rebounds. The second spring pushes the protective support rod to drive the annular block to fit into the guide pipe, thus re-forming a seal and ensuring the sealing effect of the barrel. The annular block and the conical plate form a double sealing effect. The annular block uses a mechanical method to prevent backflow of airflow, which not only smoothly discharges accumulated ash but also prevents negative pressure imbalance and air leakage inside the barrel from affecting the dust removal effect.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] First embodiment, such as Figures 1 to 4 As shown, the present invention provides a technical solution: a cyclone dust removal device for steel smelting, comprising: The support frame 1 has a ring-shaped frame block structure and fixed support legs set at the bottom of the ring-shaped frame block. A dust collector 2 is fixedly connected inside the support frame 1. An exhaust device 4 is fixedly connected at the center of the top of the dust collector 2. A discharge device 5 is fixedly connected at the center of the top of the dust collector 2. A cooling device 3 is fixedly connected to the outside of the dust collector 2. An air inlet valve 6 is located on the upper side of the outside of the dust collector 2. The outside of the air inlet valve 6 is connected to the dust collector 2, and the top of the dust collector 2 is connected to the bottom of the exhaust device 4. The support frame 1 is used to support and fix the dust collector 2. The air inlet valve 6 is connected to the dust collector 2 at an angle. The exhaust gas enters the interior of the dust collector 2 through the air inlet valve 6. The dust-laden gas enters the body of the dust collector 2 tangentially and forms a vortex. The dust settles against the wall due to centrifugal force. The dust slides down the inner wall of the dust collector 2 to the bottom of the body. The clean airflow converges to the center and is discharged from the exhaust device 4. The dust is discharged after it is collected at the bottom, thus realizing the separation of air and dust. The accumulated dust is discharged periodically by the unloading device 5 at the bottom of the dust collector 2, and the dust removal operation is continuously completed.

[0022] A trapping groove 7 is provided on the cylindrical section of the inner wall of the dust collector 2. Several trapping grooves 7 are arranged in a circular array on the inner wall of the dust collector 2. A one-way valve pipe 8 is fixedly connected to the side of the dust collector 2 away from the air inlet valve 6. A fan 9 is fixedly connected to the side of the inner wall of the one-way valve pipe 8 away from the dust collector 2. A grid plate 10 is fixedly connected to the side of the one-way valve pipe 8 close to the fan 9. Several interception grooves 7 are provided on the inner wall of the dust collector 2. The exhaust gas rotates and flows on the inner wall of the dust collector 2 and comes into contact with the interception grooves 7, thereby partially disturbing the swirling flow against the wall, impacting and intercepting dust, promoting the sedimentation and separation of particles, and moderately buffering the airflow to improve the dust removal effect. Secondly, the interception grooves 7 adopt a trapezoidal structure. When the equipment is finished and cleaning is required, the fan 9 generates wind power, which enters the dust collector 2 through the one-way valve pipe 8. The one-way valve pipe 8 is tangentially connected to the dust collector 2. The wind power rotates and flows inside the dust collector 2 like exhaust gas. The airflow comes into contact with the inner wall of the barrel and the interception grooves 7, thereby flushing the dust attached to the inner wall, eliminating dust accumulation on the groove and wall, maintaining the original airflow pattern of the inner wall of the equipment, and ensuring stable dust separation efficiency. The one-way valve pipe 8 plays the role of unidirectional airflow, preventing airflow leakage inside the dust collector 2. The grid plate 10 plays the role of preventing external impurities from entering, avoiding blockage inside the pipe, preventing affecting airflow, and ensuring normal operation of the equipment.

[0023] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 2 to 5 As shown, the cooling device 3 includes: The liquid inlet pipe 34 has a square tube structure, and a spiral tube 33 is fixedly connected to the outside of the liquid inlet pipe 34. The liquid inlet pipe 34 is connected to the spiral tube 33. The liquid outlet pipe 35 is located outside the spiral tube 33. The end of the spiral tube 33 furthest from the inlet pipe 34 is fixedly connected to the liquid outlet pipe 35 and communicates with the spiral tube 33. Cooling liquid enters from the inlet pipe 34 and flows outward from the spiral tube 33 to the liquid outlet pipe 35. Through continuous liquid delivery, the temperature of the dust collector 2 barrel wall is reduced, preventing high-temperature damage to the barrel structure and extending the service life of the equipment. The cooling promotes the agglomeration and enlargement of dust in the flue gas, improving the dust settling and separation effect, reducing deformation and aging caused by high-temperature flue gas, stabilizing the internal swirling state, and reducing the temperature of the exhaust gas to meet the requirements of subsequent emission conditions. The spiral tube 33 is spirally wound and distributed on the outside of the dust collector 2, thus conforming to the outer wall of the barrel and uniformly removing heat from the barrel, stabilizing the internal temperature environment, slowing down the thermal deformation of the shell, and promoting the cooling and dust condensation of the internal flue gas, which helps the gas and dust separation.

[0024] Cooling device 3 also includes: Cooling housing 31 has an annular structure, and the inner side of cooling housing 31 is fixedly connected to the outer side of dust collection bucket 2. The square frame 32 has a square plate structure. The outer side of the square frame 32 is fixedly connected to both sides of the inner wall of the cooling shell 31, and the opposite side of the square frame 32 is fixedly connected to the spiral tube 33. The cooling shell 31 is located outside the dust collector 2, which can protect the internal structure from impact and corrosion by external objects, isolate noise and heat leakage, stabilize the overall shape of the machine, prevent airflow leakage, and ensure stable operation of the internal dust removal process. The square frame 32 is located inside the cooling shell 31 to increase the structural rigidity of the shell and improve its stability. In addition, the square frame 32 clamps the spiral tube 33 to reinforce the stability of the pipe and maintain the stability of the liquid flow.

[0025] The exhaust device 4 includes an exhaust pipe 41, the bottom of which is fixedly connected to the top of the dust collection bin 2 and is connected to the dust collection bin 2. An annular frame 42 is fixedly connected to the inner wall of the exhaust pipe 41, and a connecting shaft 43 is rotatably connected to the inner wall of the annular frame 42. A circular plate 45 is fixedly connected to the outside of the connecting shaft 43 near the groove of the annular frame 42. A motor 46 is fixedly connected to the outside of the exhaust pipe 41, and the output end of the motor 46 is fixedly connected to one end of the connecting shaft 43. A silicone block 44 is fixedly connected to the outer circumference of the circular plate 45. After the exhaust gas is separated by the dust collector 2, the clean airflow rises through the central channel of the dust collector 2 and is discharged from the top exhaust pipe 41. After meeting the standards, it is directly discharged. It can also be purified and recycled as needed. When the equipment needs to be cleaned by backflushing with the fan 9, the connecting shaft 43 is rotated by the motor 46. The connecting shaft 43 drives the circular plate 45 to align and close with the annular frame 42, thereby controlling the airflow and preventing the airflow from scattering during backflushing and avoiding affecting the exhaust gas diversion effect of the equipment. The silicone block 44 is set on the circumference of the circular plate 45. As the circular plate 45 is fitted with the annular frame 42, it improves the sealing effect of the components, reduces wear between components, extends the service life of the equipment, and reduces noise generated by component friction.

[0026] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figures 6 to 8As shown, the unloading device 5 includes an unloading base 501. A discharge trough 502 is centrally located on the outside of the unloading base 501. A fixing frame 503 is fixedly connected to the inner wall of the discharge trough 502. An electric push rod 504 is fixedly connected to the bottom of the fixing frame 503. A conical plate 505 is fixedly connected to the output end of the electric push rod 504. The fixing frame 503 supports the electric push rod 504. The discharge trough 502 serves to discharge exhaust gas and dust. The conical plate 505 adopts a conical shell structure to reduce surface pressure on components and ensure normal operation of the equipment. The electric push rod 504 controls the conical plate 505 to move up and down inside the dust collector 2. The bottom of the conical plate 505 fits against the unloading base 501, thus achieving sealing or dust discharge. During equipment operation, the bottom of the collector is sealed to prevent interference with airflow rotation and to avoid affecting exhaust gas separation.

[0027] A hole groove 507 is provided on the outer edge of the conical plate 505. A buffer mechanism 508 is fixedly connected to the top of the conical plate 505 near the hole groove 507. A connecting end 506 is fixedly connected to the top of the unloading base 501 at a position corresponding to the hole groove 507. The hole groove 507 and the connecting end 506 are correspondingly arranged. When the electric push rod 504 controls the conical plate 505 to rise and fall, the conical plate 505 makes the hole groove 507 and the connecting end 506 fit together, thereby achieving a certain positioning effect, preventing the parts from being misaligned with the groove, and ensuring the sealing between the parts. At the same time, the buffer mechanism 508 contacts the connecting end 506, thereby playing a role in shock absorption and buffering, reducing wear on the parts.

[0028] A tripod 511 is fixedly connected to the outside of the electric push rod 504 near the inside of the cylindrical conical plate 505. An anti-conical plate 512 is fixedly connected to the bottom of the conical plate 505. A rubber block 513 is fixedly connected to the bottom of the conical plate 505 near the circumference. A guide tube 510 is fixedly connected to the bottom of the unloading base 501 near the discharge trough 502. A protective mechanism 509 is fixedly connected to the bottom of the unloading base 501. Tripod 511 supports conical plate 505 to maintain component stability, prevent component displacement due to impurity pressure, and prevent affecting component operation. Inverted conical plate 512 seals and blocks the bottom of conical plate 505, reducing the entry of impurities and preventing impurities from remaining on the inner wall of the component. Furthermore, as conical plate 505 is pressed and adhered to discharge chute 502, inverted conical plate 512 squeezes impurities to move, preventing them from affecting the adhesion between components. It also reduces component movement pressure and improves component operation stability. Rubber block 513 adheres to discharge base 501 along with conical plate 505 and deforms through compression. Rubber block 513 adheres to discharge base 501, thereby improving the sealing between components, reducing wear between components, and extending component service life. Guide pipe 510 is used to guide dust flow, facilitating dust collection and treatment.

[0029] The buffer mechanism 508 includes a buffer housing 5081. A first spring 5082 is fixedly connected to the inner wall of the buffer housing 5081. A buffer plate 5083 is fixedly connected to the other side of the first spring 5082. The outer side of the buffer plate 5083 is slidably connected to the inner wall of the buffer housing 5081. A beveled groove 5084 is formed at the bottom of the inner wall of the buffer housing 5081. When the conical plate 505 presses against the connecting end 506, the top of the connecting end 506 enters the interior of the buffer housing 5081. The connecting end 506 presses against the buffer plate 5083, and the buffer plate 5083 compresses and contracts the first spring 5082, thereby playing a role in shock absorption and buffering, avoiding hard impact damage to components. At the same time, the fit and seal are tighter, reducing air leakage from gaps. The beveled groove 5084 guides the flow of impurities, preventing impurities from entering the pipe. The first spring 5082 rebounds and pushes the buffer plate 5083 to slide, pushing the impurities out.

[0030] The protective mechanism 509 includes a protective housing 5091, a protective support rod 5092 slidably connected to the inner wall of the protective housing 5091, a protective base plate 5093 fixedly connected to the bottom of the protective support rod 5092, a second spring 5094 sleeved on the outside of the protective support rod 5092 near the inside of the protective housing 5091, and an annular block 5095 fixedly connected to the top of the protective base plate 5093 at a position corresponding to the slot of the guide tube 510. When impurities fall downwards from the discharge chute 502, dust flows from inside the guide pipe 510 and accumulates on the annular block 5095. As the weight of the accumulated dust increases, the pressure causes the protective support rod 5092 to compress and contract the second spring 5094, causing the annular block 5095 to move outwards towards the guide pipe 510, creating extra space in the component to facilitate the outward flow of dust. After the dust is discharged, the weight on the annular block 5095 decreases, and the second spring 5094 rebounds. The second spring 5094 pushes the protective support rod 5092 to drive the annular block 5095 to fit into the guide pipe 510, thereby re-forming a seal and ensuring the sealing effect of the barrel. The annular block 5095 and the conical plate 505 form a double sealing effect. The annular block 5095 uses a mechanical method to prevent backflow of airflow, which not only smoothly discharges the accumulated dust but also prevents the negative pressure imbalance inside the barrel and air leakage from affecting the dust removal effect.

[0031] When in use: The dust collector 2 adopts a structure with an upper barrel and a lower cone. An air inlet valve 6 and a one-way valve pipe 8 are provided on the upper side of the outside of the dust collector 2. Both are tangentially connected to the barrel. An exhaust device 4 is located in the middle of the top of the dust collector 2. A discharge device 5 is provided at the bottom of the dust collector 2. A cooling device 3 is provided on the outside of the dust collector 2. Exhaust gas enters the dust collector 2 through the inlet valve 6. The dust-laden gas enters the dust collector 2 tangentially and forms a vortex. The dust settles against the wall due to centrifugal force. The dust slides down the inner wall of the dust collector 2 to the bottom of the barrel. A large amount of dust accumulates in the cone part of the dust collector 2. The dust is discharged through the unloading device 5. The unloading device 5 controls the lifting and lowering of the conical plate 505 through the electric push rod 504, forming a sealed barrel and discharging function. The protective support rod 5092, the second spring 5094, and the annular block 5095 form a mechanical sealing and discharging function, thus forming a double-layer sealing and discharging function. When dust accumulates in the cone section of the dust collector 2, the conical plate 505 is lifted by the electric push rod 504, causing the dust to flow towards the guide pipe 510. The annular block 5095 fits into the guide pipe 510 to seal the space, thus preventing the airflow rotation inside the barrel from being affected. At the same time, the dust is discharged at a uniform speed. When the dust accumulates to a certain weight, the annular block 5095 disengages from the guide pipe 510, thus ensuring the dust discharge. Through the alternating opening and closing of the two-stage unloading and airlock, ash can be discharged during normal operation, avoiding the interference of air pressure fluctuations in the cavity with dust removal. After the airflow reaches the lower part of the dust collector chamber 2, it reverses and flows back. The clean airflow in the central area flows upward and is discharged from the equipment through the top exhaust pipe 41, which facilitates subsequent processing. After shutdown, the pipe openings can be sealed, and the fan 9 can generate airflow to back-blown air, relieve pressure and clean the dust, removing the dust adhering to the inner wall and ensuring the continuous and stable operation of the equipment.
