Description

Technical Field

[0001] The invention relates to the technical field of bag dust collectors, in particular to a bag dust collector for treating blast furnace gas. Background Art

[0002] Blast furnace gas is a combustible gas produced as a by-product during the blast furnace ironmaking process. This gas contains carbon monoxide, which can be further optimized for utilization. However, during the production process, this gas is mixed with a large amount of dust, and the dust needs to be separated before secondary utilization. The existing method usually uses a bag dust collector for dust removal. This dust collector can be used for the purification of blast furnace gas, and can also be used in dust removal and purification systems for other flammable and explosive gases operating under positive pressure.

[0003] During the dust removal process, dust particles in the air are trapped by the fiber structure of the bag and gradually adhere to the outer wall of the bag. However, over time, the dust accumulation on the outer wall of the bag will gradually increase, forming a thick dust layer. The presence of this dust layer will seriously affect the air permeability of the bag, resulting in reduced dust removal efficiency. When dust accumulates to a certain level, the pores of the bag will become blocked, making it difficult for air to pass through, thus affecting the overall performance of the bag dust collector. Clogged bags will also increase the operating resistance of the equipment, resulting in increased energy consumption and even possible equipment failure. Summary of the Invention

[0019] A flapping mechanism 7 is provided at the bottom of the second through hole 5 .

[0020] Furthermore, the flapping mechanism 7 includes two connecting seats 701, the outer walls of the two connecting seats 701 are rotatably connected to a plurality of connecting plates 702, the end of the connecting plate 702 away from the connecting seat 701 is rotatably connected to a rotating block 703, and the outer wall of the rotating block 703 is fixedly connected to a flapping rod 704, the bottom of the upper connecting seat 701 is fixedly connected to a connecting rod 705, and the outer wall of the connecting rod 705 passes through and is slidably connected to the interior of the lower connecting seat 701, a spring 706 is fixedly connected between the two connecting seats 701, and the outer wall of the upper connecting seat 701 is fixedly connected to an L-shaped rod 707, 6 is fixedly connected to the first support plate 12 at the bottom, and the bottom of the first support plate 12 is fixedly connected to the tension spring 13, and the end of the tension spring 13 away from the first support plate 12 is fixedly connected to the second support plate 14, the outer wall of the connecting rod 705 passes through and is slidably connected to the inside of the first support plate 12, and the end of the connecting rod 705 away from the connecting seat 701 is fixedly connected to the top of the second support plate 14, and a fan 21 is fixedly installed on the top of the inner wall of the dust collector 1, and the outer wall of the dust collector 1 is provided with an air inlet pipe 22 extending to the inside of the dust collector 1, and the outer wall of the dust collector 1 is provided with an air outlet pipe 23 extending to the inside of the dust collector 1.

[0021] In this embodiment, in addition to larger particulate matter, the blast furnace gas also contains fine matter, such as iron oxide, manganese oxide, etc. These particulate matter can be effectively removed by a bag dust collector to prevent them from causing harm to the environment and human health. First, the blast furnace gas delivery pipe is connected to the air inlet pipe 22, and then the blast furnace gas will enter the interior of the dust removal box 1 through the air inlet pipe 22, and then the fan 21 is driven to output, and then the gas above the isolation plate 2 will be extracted by the fan 21, and then a negative pressure will be formed in the space above the isolation plate 2, and then the blast furnace gas in the space below the isolation plate 2 will be filtered by the dust bag 6, so that the particulate dust in the blast furnace gas stays on the outer surface of the dust bag 6, and then the filtered blast furnace gas will pass through the second through hole 5 and the inside of the first through hole 3, thereby flowing into the space above the isolation plate 2, and then be extracted by the fan 21, and then be discharged through the inside of the outlet pipe 23, thereby completing the function of filtering the particulate dust in the blast furnace gas.

[0022] When filtering the blast furnace gas, it is necessary to clean the particulate dust remaining on the outer surface of the dust bag 6 to keep the surface of the dust bag 6 clean and maintain its efficient filtering performance. The top of the dust box 1 is fixedly connected to a first fixing frame 15, and the interior of the first fixing frame 15 is rotatably connected to a second rotating rod 16, one end of the second rotating rod 16 is fixedly installed with an impeller 17, and the end of the second rotating rod 16 away from the impeller 17 is fixedly connected to a cam 18, the top of the isolation plate 2 is fixedly connected to two second fixing frames 19, and a fixing rod 20 is fixedly connected between the two second fixing frames 19, so the wind When the machine 21 extracts the space above the isolation plate 2, the airflow drives the impeller 17 to rotate, and then the impeller 17 drives the cam 18 to rotate synchronously through the second rotating rod 16. During the rotation of the cam 18, the convex corner of the cam 18 squeezes the fixing rod 20, and then the fixing rod 20 drives the isolation plate 2 to move downward through the second fixing frame 19, so that the isolation plate 2 slides downward along the inner wall of the dust removal box 1, and at the same time drives the flapping mechanism 7 to move downward through the mounting ring 4. The end of the L-shaped rod 707 away from the connecting seat 701 is fixedly connected to the bottom of the mounting ring 4, so that the L-shaped rod 707 drives the connecting seat 701 to rotate synchronously. The seat 701 moves downward, compressing the spring 706 at the same time, and then the distance between the two connecting seats 701 becomes shorter, thereby squeezing the connecting plate 702. Since the two rotating blocks 703 are fixedly connected with the flapping rod 704, the distance between the ends of the two connecting plates 702 that are close to each other will not change, so that the connecting plate 702 will drive the flapping rod 704 to move outward through the rotating block 703. The outer wall of the flapping rod 704 corresponds to the inner wall of the dust bag 6. The lower connecting seat 701 is fixedly connected to the bottom of the dust bag 6, and the inner wall of the dust bag 6 will be squeezed during the movement of the flapping rod 704. The flapping can clean the particulate dust adsorbed on the outer wall of the dust bag 6, so that the particulate dust falls downward from the inside of the dust box 1 to the inside of the ash hopper 8, thereby achieving the purpose of cleaning the dust bag 6 while removing the blast furnace gas, and avoiding a large amount of particulate dust adsorbed on the outer surface of the dust bag 6 and affecting the filtering effect. After that, when the convex corner of the cam 18 passes over the fixed rod 20, the spring 706 will be elastically reset, and then the isolation plate 2 will be driven to slide upward and reset along the inner wall of the dust box 1. Through the continuous rotation of the cam 18, the flapping rod 704 can continuously flap the dust bag 6.

[0023] As described above, the rotation of the impeller 17 causes the isolation plate 2 to slide downward, and then the mounting ring 4 drives the connecting seat 701 to move downward through the L-shaped rod 707, thereby squeezing the slapping rod 704 fixedly connected between the rotating blocks 703, and the particulate dust on the outer surface of the dust bag 6 can be shaken off. The slapping rod 704 continuously beats, thereby achieving real-time cleaning of the outer surface of the dust bag 6, ensuring the efficient filtering performance of the dust bag 6, avoiding the accumulation and blockage of particulate dust, and thus extending the service life of the dust bag 6.

[0024] Embodiment 2: Based on the above embodiment, a collecting mechanism 11 is provided at one end of the first rotating rod 10 .

[0025] An upper connecting groove 24 is provided on the outer wall of the transmission cylinder 9, and the inner wall of the upper connecting groove 24 is connected to the interior of the ash hopper 8. A collecting box 27 is fixedly connected to the bottom of the transmission cylinder 9, and a lower connecting groove 26 is provided on the outer wall of the transmission cylinder 9. The inner wall of the lower connecting groove 26 is connected to the interior of the collecting box 27. A spiral blade 25 is fixedly connected to the outer wall of the first rotating rod 10.

[0026] Furthermore, the collecting mechanism 11 includes a connecting ring 1101, and the side wall of the connecting ring 1101 is fixedly connected to a first connecting column 1102, the outer wall of the first connecting column 1102 is rotatably connected to a pawl 1103, the outer wall of the connecting ring 1101 is fixedly connected to a second connecting column 1104, and the outer wall of the second connecting column 1104 is fixedly connected to a torsion spring 1105, the outer wall of the pawl 1103 is matched and engaged with a ratchet 1106, the bottom of the second support plate 14 is fixedly connected to a push rod 1107, and the bottom of the push rod 1107 is fixedly connected to a rack 1108, and the inner wall of the tooth groove of the rack 1108 is matched and engaged with the outer wall teeth of the ratchet 1106.

[0027] The dust collecting bag 6 is cleaned by the flapping mechanism 7. Since the interior of the dust collecting box 1 is connected to the interior of the ash hopper 8, the particulate dust can fall into the interior of the ash hopper 8. Since the interior of the transmission drum 9 is connected to the interior of the ash hopper 8, a large amount of particulate dust will fall into the interior of the transmission drum 9 through the spiral blades 25, which may affect the filtration of the blast furnace gas again. Therefore, it is necessary to collect it in a centralized manner. The connecting seat 701 drives the connecting rod 705 to move downward synchronously, and then the connecting rod 705 drives the second support plate 14 to move downward, and at the same time, the tension spring 13 is stretched, and the outer wall of the push rod 1107 passes through and is slidably connected to the interior of the ash hopper 8. During the downward movement of the second support plate 14, the push rod 1107 is driven to move downward synchronously, so that the rack 1108 drives the ratchet 1106 to rotate. The inner center of the connecting ring 1101 is fixedly connected to one end of the first rotating rod 10, and then the ratchet 1106 drives the connecting ring 1101 to rotate through the pawl 1103. 101 will drive the upper connecting groove 24 to rotate through the first rotating rod 10, so that the particulate dust inside the transmission cylinder 9 can be transported to the inside of the collecting box 27 through the lower connecting groove 26, thereby completing the collection of the particulate dust, effectively preventing the particulate dust from mixing with the blast furnace gas again, thereby avoiding possible re-pollution problems. When the spring 706 is reset, the connecting rod 705 and the tension spring 13 will drive the second support plate 14 to move upward, and then the push rod 1107 will drive the rack 1108 to move upward. The pawl 1103 is moved upward step by step, causing the ratchet 1106 to rotate in the opposite direction. At the same time, the inner wall teeth of the ratchet 1106 squeeze the outer wall of the pawl 1103. Then the pawl 1103 rotates along the first connecting column 1102 as the axis, and squeezes the torsion spring 1105, thereby avoiding driving the connecting ring 1101 to rotate in the opposite direction. When the ratchet 1106 stops rotating, the pawl 1103 is reset by the elastic force of the torsion spring 1105, and then it will re-engage with the inner wall teeth of the ratchet 1106.

[0028] As described above, the dust bag 6 is beaten by the beating rod 704, and the particulate dust is shaken into the interior of the transmission cylinder 9. At the same time, the rack 1108 is driven downward by the second support plate 14, so that the ratchet 1106 drives the connecting ring 1101 to rotate, and then the particulate dust in the transmission cylinder 9 is sent into the collecting box 27 through the upper connecting groove 24. The particulate dust can be quickly discharged from the interior of the dust removal box 1 while dust removal, avoiding the phenomenon of accumulation inside the dust removal box 1, preventing the particulate dust from polluting the blast furnace gas again, and effectively improving the efficiency and purification quality of blast furnace gas filtration.

[0029] While filtering the blast furnace gas, it is necessary to clean the particulate dust remaining on the outer surface of the dust bag 6 to keep the surface of the dust bag 6 clean and maintain its efficient filtering performance. The air flow will drive the impeller 17 to rotate, and then the impeller 17 will drive the cam 18 to rotate synchronously through the second rotating rod 16. During the rotation of the cam 18, the convex corner of the cam 18 will squeeze the fixed rod 20, and then the fixed rod 20 will drive the isolation plate 2 through the second fixing bracket 19. The slapping mechanism 7 is driven downward by the mounting ring 4, and the end of the L-shaped rod 707 away from the connecting seat 701 is fixedly connected to the bottom of the mounting ring 4, so that the L-shaped rod 707 drives the connecting seat 701 to move downward, and the spring 706 is compressed, and then the distance between the two connecting seats 701 is shortened, thereby squeezing the connecting plate 702. Since the slapping rod 704 is fixedly connected between the two rotating blocks 703, the two connecting plates 702 are close to each other. The distance between the two ends will not change, so the connecting plate 702 will drive the slapping rod 704 to move outward through the rotating block 703. The outer wall of the slapping rod 704 corresponds to the inner wall of the dust bag 6. The connecting seat 701 below is fixedly connected to the bottom of the dust bag 6. During the movement of the slapping rod 704, the inner wall of the dust bag 6 will be slapped, which can clean the particulate dust adsorbed on the outer wall of the dust bag 6 and make the particulate dust fall downward from the inside of the dust box 1 to the inside of the ash hopper 8, thereby achieving the purpose of dust removal for blast furnace gas at the same time. At the same time, the dust bag 6 can also be cleaned to prevent a large amount of particulate dust from being adsorbed on the outer surface of the dust bag 6 and affecting the filtering effect. Later, when the convex corner of the cam 18 passes over the fixed rod 20, the spring 706 will be elastically reset, and then the isolation plate 2 will slide upward along the inner wall of the dust box 1 to reset. Through the continuous rotation of the cam 18, the beating rod 704 can continuously beat the dust bag 6, ensuring the efficient filtering performance of the dust bag 6, avoiding the accumulation and blockage of particulate dust, and thus extending the service life of the dust bag 6.
