Description

Technical Field

[0001] This invention relates to the field of dust removal technology, and in particular to a baghouse dust collector for steel production that prevents clogging. Background Technology

[0002] Baghouse dust collectors, also known as bag filters, are the most widely used dry, high-efficiency dust collection equipment in the industrial field. Their core technology relies on filter bags and fibers to achieve gas-solid separation, efficiently handling dust. The working principle of a baghouse dust collector is as follows: dust-laden gas enters the equipment; large dust particles first settle by gravity in the hopper; fine dust particles are carried by the airflow into the middle chamber, where they are intercepted and adsorbed by the fibers on the filter bag surface and the initial dust layer formed therein. Clean gas then passes through the filter bags and exits into the upper chamber. In the steel production process, a large amount of dust is generated, thus requiring the treatment of dust impurities.

[0003] For example, a bag filter dust collector, as disclosed in Chinese Patent Publication No. CN221244484U, includes a tank, a dust hopper located below the tank, and a cover plate located above the tank. The cover plate has an exhaust pipe, and a perforated plate is located inside the tank corresponding to the position below the cover plate. The perforated plate has assembly holes for installing filter bags. An intake pipe is located on the tank corresponding to the position below the perforated plate, positioned on one side of the tank. A vibration hood is located inside the tank corresponding to the position below the intake pipe. A mounting bracket for installing the vibration hood is located on the tank. The vibration hood is a dome-shaped structure, and a material passage gap exists between the vibration hood and the inner wall of the tank. A fastener is located on the side of the vibration hood facing the perforated plate, and a vibration generator is located on the other side. The filter bags have connecting buckles that cooperate with the fasteners, and a bag cage is located inside the filter bags to hold the connecting buckles in place. By installing a vibration hood inside the tank and connecting the filter bags to the vibration hood, dust on the filter bags is removed by vibration.

[0004] According to existing technical references, dust on the cloth bag can be removed by vibration. However, with prolonged use, fine dust particles will adhere to the surface of the cloth bag. The more dust accumulates, the more likely it is to cause blockage, making it impossible to remove dust properly. In addition, dust and impurities are prone to backflow, affecting the treatment of dust and impurities. Summary of the Invention

[0005] To solve the above technical problems, the present invention is implemented through the following technical solution: A baghouse dust collector for steel production that prevents clogging, comprising: The box body, and the slag discharge port installed in the middle of the bottom of the box body, the top of the inner cavity of the box body is equipped with a pulse generator, and the inner cavity of the box body is equipped with an air intake mechanism near the bottom. The bag filter mechanism includes a baffle plate and a circular through hole. The baffle plate is fixedly installed on the inner wall of the housing near the pulse generator. The circular through hole is formed on the surface of the baffle plate. A strip-shaped filter bag is fixedly installed at the bottom of the baffle plate near the circular through hole. A double-cone head shell is fixedly connected to the surface of the strip-shaped filter bag. A guide groove is formed at the conical surface at the bottom of the double-cone head shell. An auxiliary component is installed between the bottom of the baffle plate and the bottom end of the strip-shaped filter bag. As the airflow moves from bottom to top, the airflow passes through the strip... The strip-shaped filter element filters out dust, achieving a dust removal effect. The filtered clean air passes through the circular through-hole and moves upward. At the same time, the airflow carries dust and comes into contact with the surface of the double-cone head shell. The spiral guide groove makes the airflow carrying dust and impurities spiral upward. The dust and impurities are subjected to centrifugal force, which centrifugally throws off the dust, assisting in dust removal and reducing dust adhesion to the surface of the strip-shaped filter element. This effectively prevents clogging. Furthermore, the pulse generator uses jet airflow to further clean the dust on the surface of the strip-shaped filter element. The suction mechanism includes a connecting pipe and a bent air duct. The connecting pipe is fixedly installed on the top of the housing surface. The top end of the bent air duct is detachably fixed to the end of the connecting pipe away from the housing. A suction fan is installed at the bottom end of the bent air duct. An exhaust duct is connected to the air outlet on the surface of the suction fan. A support spring is fixedly connected to the inner wall of the connecting pipe. A conical plug is fixedly connected to the end of the support spring away from the inner wall of the connecting pipe. A blind hole is opened at the end of the conical plug away from the support spring. The suction is achieved by the suction of the suction fan. The force, and with the connection between the bent air passage and the connecting pipe, causes the conical plug to move towards the bent air passage after being sucked by the airflow. The supporting spring is squeezed and deformed elastically, causing the conical plug to separate from the air inlet at the end of the connecting pipe. This allows the air inlet of the connecting pipe to be opened, allowing air to be sucked into the box. As the airflow blows onto the conical plug, the airflow is concentrated at the blind hole, increasing the blowing force of the conical plug and causing the gas in the box to move from bottom to top, which helps with subsequent dust removal. When dust removal is finished and the suction fan is turned off, the gas stops flowing, and the blowing force of the airflow on the conical plug disappears. Under the elastic force of the support spring, the conical plug moves in the opposite direction, so that the conical surface of the conical plug can fit against the air inlet at the end of the connecting pipe again, sealing the air inlet at the end of the connecting pipe and preventing dust and impurities from flowing back in.

[0006] Furthermore, the circular through holes are evenly distributed on the surface of the baffle plate, the strip-shaped filter bag is connected to the circular through holes, and the strip-shaped filter bag is installed directly below the circular through holes.

[0007] Furthermore, the strip-shaped filter bag is installed vertically and is evenly distributed at the bottom of the baffle plate. The flow guide groove is spiral-shaped and is evenly distributed at the conical surface at the bottom of the double-cone head shell.

[0008] Furthermore, the auxiliary component includes a connecting threaded rod and a dividing frame. The top of the connecting threaded rod is fixedly installed at the side of the bottom of the baffle plate. The dividing frame is fixedly installed at the bottom of the strip-shaped filter element. A mounting ear is fixedly connected to the surface of the dividing frame near the bottom of the connecting threaded rod. The bottom of the connecting threaded rod passes through the center of the mounting ear. A locking nut is threadedly installed on the surface of the connecting threaded rod near the top of the mounting ear. By installing the dividing frame at the bottom of the strip-shaped filter element, a downward pulling force can be applied to the dividing frame, so that the strip-shaped filter element is in a tensioned state after being pulled by the dividing frame. The surface of the strip-shaped filter element is less prone to wrinkles, which can prevent dust and impurities from being hidden in the wrinkles. At the same time, reducing the wrinkles on the surface of the strip-shaped filter element facilitates the passage of gas through the strip-shaped filter element, ensuring smooth airflow and promoting dust removal.

[0009] Furthermore, the connecting threaded rod is installed vertically, and there are two connecting threaded rods, which are symmetrically installed along the central axis of the partition plate. The bottom of the locking nut fits against the top of the mounting ear.

[0010] Furthermore, the bent air passage, connecting pipe, and housing are interconnected, the supporting spring is installed at an angle, and the conical surface on the outer side of the conical plug fits against the air inlet on the inner wall of the connecting pipe.

[0011] Furthermore, the air intake mechanism includes a right-angled air intake duct and a dust collection assembly. The right-angled air intake duct is fixedly installed on the inner wall of the housing, and its intake end penetrates the inner wall of the housing and extends to its exterior. The dust collection assembly is installed at the bottom of the inner cavity of the housing, near the right-angled air intake duct. A first round rod is fixedly connected to the top of the surface of the right-angled air intake duct, and a conical hopper is fixedly connected to the top of the first round rod. A spiral blade is fixedly connected to the air outlet inside the right-angled air intake duct, which draws out gas from the housing. The external airflow carries dust into the right-angled air intake, and under the guidance of the spiral blades, the gas ejected from the air outlet at the top of the right-angled air intake forms a swirling flow. Some large particles of impurities are thrown out by centrifugal force and come into contact with the inner wall of the conical hopper. The inner wall of the conical hopper blocks the large particles of impurities, causing them to fall downwards, while the airflow continues to swirl upwards, evenly throwing out fine dust impurities and spreading them in all directions. This ensures that the fine dust carried by the airflow comes into even contact with the strip-shaped bag filter element, making it less likely for dead corners to appear.

[0012] Furthermore, the inner diameter of the conical hopper gradually increases from top to bottom, and the conical hopper is installed directly above the air outlet of the right-angled air inlet.

[0013] Furthermore, the dust collection assembly includes a receiving funnel, the edge of which is fixedly connected to the inner wall of the housing. The receiving funnel is installed below the right-angled air inlet. A second round rod is fixedly connected to the bottom of the receiving funnel, and a conical cap is fixedly connected to the bottom end of the second round rod. As large particles hit the inner wall of the conical funnel and fall into the receiving funnel, the dust particles gather towards the center and fall downwards from the round hole at the center of the receiving funnel. The conical cap, installed directly below the receiving funnel, can block the central hole of the receiving funnel, preventing the collected particles and debris from coming out.

[0014] Furthermore, the axis of the receiving funnel coincides with the axis of the conical hopper, there are three second round rods, and the three second round rods are evenly distributed along the circumferential direction of the axis of the conical cap. The conical cap is installed directly below the receiving funnel, and the tip of the conical cap faces upward.

[0015] The beneficial effects of the technical solution provided by this invention include: 1. By installing a segmented frame at the bottom of the strip-shaped filter element, a downward pulling force can be applied to the segmented frame, so that the strip-shaped filter element is in a tensile state after being pulled by the segmented frame. The surface of the strip-shaped filter element is less prone to wrinkles, which can prevent dust and impurities from being hidden in the wrinkles. At the same time, reducing the wrinkles on the surface of the strip-shaped filter element makes it easier for gas to pass through the strip-shaped filter element, ensuring smooth airflow and promoting dust removal.

[0016] 2. As the airflow moves from bottom to top, it passes through the strip-shaped filter element, and the dust is filtered down by the strip-shaped filter element, achieving the effect of dust removal. The filtered clean air passes through the circular through-hole and moves upward. At the same time, the airflow carries the dust and comes into contact with the surface of the double-cone head shell. The spiral shape of the guide groove makes the airflow carrying dust and impurities spiral upward. The dust and impurities are subjected to centrifugal force, which centrifugally throws off the dust, assists in dust removal, and reduces the amount of dust adhering to the surface of the strip-shaped filter element, which can effectively prevent clogging. Furthermore, the pulse generator uses jet airflow to further clean the dust on the surface of the strip-shaped filter element.

[0017] 3. When the suction fan is turned off, the gas stops flowing and the airflow force on the conical plug disappears. Under the elastic force of the support spring, the conical plug moves in the opposite direction, so that the conical surface of the conical plug can fit against the air inlet at the end of the connecting pipe again, sealing the air inlet at the end of the connecting pipe and preventing dust and impurities from flowing back in.

[0018] Fourth, under the guidance of the spiral blades, the gas ejected from the air outlet at the top of the right-angled air inlet forms a swirling flow. Some large particles of impurities are thrown out by centrifugal force and come into contact with the inner wall of the conical hopper. The inner wall of the conical hopper blocks the large particles of impurities, causing them to fall downwards, while the airflow continues to swirl upwards, evenly throwing out fine dust impurities and spreading them in all directions. This ensures that the fine dust carried by the airflow comes into even contact with the strip-shaped bag filter element, making it less likely for dead corners to appear.

[0019] 5. As large particles hit the inner wall of the conical hopper and fall into the receiving funnel, the dust particles gather towards the center and fall downwards from the round hole at the center of the receiving funnel. The conical cap installed directly below the receiving funnel can block the central hole of the receiving funnel, preventing the collected particles and debris from coming out.

[0022] Example 1, see Figures 1-5 A technical solution is provided: A baghouse dust collector for steel production that prevents clogging, comprising: Box 1, and slag discharge port 2 installed at the middle of the bottom of box 1, pulse generator 3 installed at the top of the inner cavity of box 1, and air intake mechanism 4 installed in the inner cavity of box 1 near the bottom. The bag filter mechanism 5 includes a baffle plate 51 and a circular through hole 52. The baffle plate 51 is fixedly installed on the inner wall of the housing 1 and near the pulse generator 3. The circular through hole 52 is opened on the surface of the baffle plate 51. A strip-shaped filter bag element 53 is fixedly installed at the bottom of the baffle plate 51 and near the circular through hole 52. A double-cone head shell 54 is fixedly connected to the surface of the strip-shaped filter bag element 53. A guide groove 55 is opened at the conical surface at the bottom of the double-cone head shell 54. An auxiliary component 56 is installed between the bottom of the baffle plate 51 and the bottom end of the strip-shaped filter bag element 53. As the airflow moves from bottom to top, the airflow... Dust passes through the strip-shaped filter element 53 and is filtered down by the strip-shaped filter element 53, achieving the effect of dust removal. The filtered clean air passes through the circular through hole 52 and moves upward. At the same time, the airflow carries dust and comes into contact with the surface of the double cone head shell 54. The spiral shape of the guide groove 55 makes the airflow carrying dust and impurities spiral upward. The dust and impurities are subjected to centrifugal force, which centrifugally throws off the dust, assists in dust removal, and reduces the amount of dust adhering to the surface of the strip-shaped filter element 53, which can effectively prevent clogging. Furthermore, the pulse generator 3 uses jet airflow to further clean the dust on the surface of the strip-shaped filter element 53. Circular through holes 52 are evenly distributed on the surface of the baffle plate 51. The strip-shaped filter element 53 is connected to the circular through holes 52 and is installed directly below the circular through holes 52.

[0023] The strip-shaped filter bag 53 is installed vertically and is evenly distributed at the bottom of the baffle plate 51. The guide groove 55 is spiral and is evenly distributed at the bottom of the conical surface of the double cone head shell 54.

[0024] Auxiliary component 56 includes a connecting threaded rod 561 and a dividing frame 562. The top of the connecting threaded rod 561 is fixedly installed at the bottom edge of the baffle plate 51. The dividing frame 562 is fixedly installed at the bottom end of the strip-shaped filter element 53. A mounting ear 563 is fixedly connected to the surface of the dividing frame 562 near the bottom end of the connecting threaded rod 561. The bottom end of the connecting threaded rod 561 passes through the center of the mounting ear 563. A screw thread is fixed to the surface of the connecting threaded rod 561 near the top end of the mounting ear 563. The filter element 53 is fitted with a locking nut 564 and a grid frame 562 installed at the bottom. The grid frame 562 can apply a downward pulling force to the grid frame 562, so that the filter element 53 is in a tensioned state after being pulled by the grid frame 562. The surface of the filter element 53 is less prone to wrinkles, which can prevent dust and impurities from being hidden in the wrinkles. At the same time, reducing the wrinkles on the surface of the filter element 53 makes it easier for gas to pass through the filter element 53, so that the air circulation is smooth and promotes the removal of dust.

[0025] The connecting threaded rod 561 is installed vertically. There are two connecting threaded rods 561, and the two connecting threaded rods 561 are installed symmetrically along the central axis of the partition plate 51. The bottom of the locking nut 564 fits against the top of the mounting ear 563.

[0026] Example 2, based on Example 1, see [link / reference] Figures 1 to 7 A technical solution is provided: The suction mechanism 6 includes a connecting pipe 61 and a bent air duct 62. The connecting pipe 61 is fixedly installed on the top of the surface of the housing 1. The top of the bent air duct 62 is detachably fixed to the end of the connecting pipe 61 away from the housing 1. A suction fan 63 is installed at the bottom of the bent air duct 62. An exhaust duct 64 is connected to the air outlet on the surface of the suction fan 63. A support spring 65 is fixedly connected to the inner wall of the connecting pipe 61. A conical plug 66 is fixedly connected to the end of the support spring 65 away from the inner wall of the connecting pipe 61. A blind hole 67 is opened at the end of the conical plug 66 away from the support spring 65. When the operator turns on the suction fan 63, the suction force of the suction fan 63, combined with the connection between the bent air duct 62 and the connecting pipe 61, causes the conical plug 66 to move towards the bent air duct 62 due to the suction force of the airflow. Furthermore, the supporting spring 65 undergoes elastic deformation under compression, causing the conical plug 66 to separate from the air inlet at the end of the connecting pipe 61. This allows the air inlet of the connecting pipe 61 to be opened, drawing air into the housing 1. The airflow then blows onto the conical plug 66, and the airflow is directed towards the blind hole 67, concentrating the blowing force of the airflow and increasing the blowing force of the conical plug 66. This causes the gas in the housing 1 to move upwards, aiding in subsequent dust removal. When dust removal is completed and the suction fan 63 is turned off, the gas flow stops, and the blowing force of the airflow on the conical plug 66 disappears. Under the elastic force of the supporting spring 65, the conical plug 66 moves in the opposite direction, allowing its conical surface to re-fit against the air inlet at the end of the connecting pipe 61, sealing the air inlet and preventing backflow of dust and impurities.

[0027] The bent air passage 62, the connecting pipe 61 and the box 1 are connected. The supporting spring 65 is installed at an angle. The conical surface of the outer side of the conical plug 66 fits against the air inlet of the inner wall of the connecting pipe 61.

[0028] Example 3, based on Examples 1 and 2, see below. Figures 1 to 9 A technical solution is provided: The air intake mechanism 4 includes a right-angled air intake duct 41 and a dust collection assembly 42. The right-angled air intake duct 41 is fixedly installed on the inner wall of the housing 1, and the air intake end of the right-angled air intake duct 41 penetrates the inner wall of the housing 1 and extends to its outside. The dust collection assembly 42 is installed at the bottom of the inner cavity of the housing 1 and close to the right-angled air intake duct 41. A first round rod 43 is fixedly connected to the top of the surface of the right-angled air intake duct 41, and a conical hopper 44 is fixedly connected to the top of the first round rod 43. A spiral blade 45 is fixedly connected to the air outlet inside the right-angled air intake duct 41. As the gas inside the housing 1 is drawn out... External airflow carrying dust enters the interior of the right-angled air intake duct 41. Guided by the spiral blades 45, the gas ejected from the air outlet at the top of the right-angled air intake duct 41 swirls. Some large particles of impurities are thrown out by centrifugal force and come into contact with the inner wall of the conical hopper 44. The inner wall of the conical hopper 44 blocks the large particles of impurities, causing them to fall downwards, while the airflow continues to swirl upwards, evenly throwing out fine dust impurities and spreading them in all directions. This ensures that the fine dust carried by the airflow comes into even contact with the strip-shaped bag filter element 53, making it less likely for dead corners to appear.

[0029] The conical hopper 44 has an inner diameter that gradually increases from top to bottom, and the conical hopper 44 is installed directly above the air outlet of the right-angled air intake duct 41.

[0030] The dust collection assembly 42 includes a receiving funnel 421. The edge of the surface of the receiving funnel 421 is fixedly connected to the inner wall of the housing 1. The receiving funnel 421 is installed below the right-angled air inlet 41. A second round rod 422 is fixedly connected to the bottom of the receiving funnel 421. A conical cap 423 is fixedly connected to the bottom end of the second round rod 422. As large particles hit the inner wall of the conical hopper 44 and fall into the receiving funnel 421, the dust particles gather towards the center and fall downward from the round hole at the center of the receiving funnel 421. The conical cap 423 is installed directly below the receiving funnel 421, which can block the central hole of the receiving funnel 421 and prevent the collected particles and debris from coming out.

[0031] The axis of the receiving funnel 421 coincides with the axis of the conical hopper 44. There are three second round rods 422, and the three second round rods 422 are evenly distributed along the circumferential direction of the axis of the conical cap 423. The conical cap 423 is installed directly below the receiving funnel 421, with the tip of the conical cap 423 facing upward.

[0032] When in use, first open the cover plate on the surface of the box 1, and use the dividing frame 562 to install the bottom of the strip bag filter element 53. The dividing frame 562 can be applied downward pulling force, so that the strip bag filter element 53 is in a tensioned state after being pulled by the dividing frame 562, and then install the cover plate in its original position. At this time, the operator starts the suction fan 63. Using the suction force of the suction fan 63, and with the connection between the bent air passage 62 and the connecting pipe 61, the conical plug 66 is pulled by the airflow and moves towards the bent air passage 62. The supporting spring 65 is squeezed and deformed elastically, causing the conical plug 66 to separate from the air inlet at the end of the connecting pipe 61. The air inlet of the connecting pipe 61 can then be opened to suck air into the box 1. As the airflow blows onto the conical plug 66, the airflow blows onto the blind hole 67, which can concentrate the blowing force of the airflow, increase the blowing force of the conical plug 66, and cause the gas in the box 1 to move from bottom to top. As the gas inside the housing 1 is drawn out, the external airflow carrying dust enters the interior of the right-angled air intake duct 41. Under the guidance of the spiral blades 45, the gas ejected from the air outlet at the top of the right-angled air intake duct 41 forms a swirling flow. Some large particles of impurities are thrown out by centrifugal force and come into contact with the inner wall of the conical hopper 44. The inner wall of the conical hopper 44 blocks the large particles of impurities, causing them to fall downwards, while the airflow continues to swirl upwards, evenly throwing out fine dust impurities and spreading them in all directions, so that the fine dust carried by the airflow comes into even contact with the strip-shaped bag filter element 53. At the same time, as large particles hit the inner wall of the conical hopper 44 and fall into the receiving funnel 421, the dust particles gather towards the center and fall down from the round hole at the center of the receiving funnel 421. The conical cap 423 is installed directly below the receiving funnel 421 to block the central hole of the receiving funnel 421 and prevent the collected particles and debris from coming out. As the airflow moves from bottom to top, it passes through the strip-shaped filter element 53, and the dust is filtered down by the strip-shaped filter element 53, achieving the effect of dust removal. The filtered clean air passes through the circular through hole 52 and moves upward. At the same time, the airflow carries the dust and comes into contact with the surface of the double cone head shell 54. The spiral shape of the guide groove 55 allows the airflow to carry the dust and impurities upward in a spiral. The dust and impurities are subjected to centrifugal force, which centrifugally removes the dust, assists in dust removal, and reduces the amount of dust adhering to the surface of the strip-shaped filter element 53, which can effectively prevent clogging. Furthermore, the pulse generator 3 uses a jet of airflow to further clean the dust on the surface of the strip-shaped filter element 53. When dust removal is completed and the suction fan 63 is turned off, the gas stops flowing, and the blowing force of the airflow on the conical plug 66 disappears. Under the elastic force of the support spring 65, the conical plug 66 moves in the opposite direction, so that the conical surface of the conical plug 66 can be put into contact with the air inlet at the end of the connecting pipe 61 again, sealing the air inlet at the end of the connecting pipe 61 to prevent dust and impurities from flowing back in, and opening the gate at the slag discharge port 2 to discharge the dust and impurities that have fallen to the bottom of the inner cavity of the box 1.

[0033] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. The scope of protection of the present invention should be determined by the scope of the claims.
