Description

Technical Field

[0001] The invention relates to the technical field of gas dry bag dust removal, in particular to a gas dry bag dust collector for an SRV furnace gas purification system. Background Art

[0002] SRV furnace is a smelting reduction ironmaking device, and its gas purification system is an important part of this device.

[0003] SRV furnace gas purification system refers to a series of equipment and processes for purifying the gas generated by the SRV furnace. Its main purpose is to remove impurities such as fly ash, tar, naphthalene, ammonia, hydrogen sulfide, etc. in the gas to ensure the smooth progress of subsequent processes and reduce environmental pollution. The dust bag is the heart of the bag filter. It is generally called a dust bag or a dust filter bag. The dust bag is a key part of the operation of the bag filter. Usually, the cylindrical filter bag is hung vertically in the dust collector.

[0004] As the filtering process continues, the dust on the outer surface of the bag will gradually accumulate, increasing the filtering resistance. When the resistance reaches a certain level, the bag needs to be cleaned. The cleaning process usually adopts pulse spraying technology, which sprays the bag with compressed air instantly, causing the filter bag to expand and vibrate rapidly, so that the dust attached to the outer surface of the filter bag is separated from the filter bag under the action of inertia and reverse airflow and falls into the ash hopper.

[0005] Pulse jet technology is only applicable to cylindrical bag filters. When the bag filters are bag-shaped, the surface of the filter is relatively soft, which will greatly reduce the cleaning effect of the pulse jet technology. Therefore, a cleaning device that is beneficial to bag-shaped bag filters is needed to remove dust from the bags. Summary of the invention

[0023] A fixing plate 11, the lower end surface of the fixing plate 11 is fixedly connected to the upper end surface of the filter box 3, the upper end surface of the fixing plate 11 is also provided with a through notch, the groove wall of the notch is rotatably connected with a rotating rod 13, the upper end surface of the filter box 3 is also provided with a motor 12, the output end of the motor 12 is belt-driven with the surface of the rotating rod 13, the end surface of the rotating rod 13 is also fixedly connected with a cam 14, the end surface of the cam 14 away from the rotating rod 13 is fixedly connected with a sliding column 20, the surface of the sliding column 20 is slidably connected with a sliding frame 21, the lower end outer surface of the sliding frame 21 is fixedly connected with a connecting frame 19, the lower end surface of the connecting frame 19 is fixedly connected with a sliding block 16, the upper end surface of the sliding block 16 is provided with a through sliding groove 27, the inner wall of the sliding groove 27 is slidably connected with a limiting rod 15, and the lower end surface of the limiting rod 15 is fixedly connected with the upper end surface of the filter box 3.

[0024] The mounting frame 17, the outer surface of the mounting frame 17 is fixedly connected to the surface of the sliding block 16, the inner wall of the mounting frame 17 is rotatably connected to a connecting rod 7, the surface of the connecting rod 7 rotates through the upper end surface of the filter box 3, and the lower end surface of the connecting rod 7 is fixedly connected to a magnet 2 36.

[0025] In this embodiment, the gas to be filtered is passed into the air inlet pipe 6, and enters the air inlet box 2 through the air inlet pipe 6, and then enters the filter box 3 through the bag filter 9. Next, the gas in the filter box 3 is extracted through a pipeline connected to the air outlet pipe 5. Under long-term use, dust will adhere to the bag filter 9. When the dust needs to be cleaned, the motor 12 is started to drive the rotating rod 13 to rotate, and the rotation of the rotating rod 13 further drives the cam 14 to rotate. The rotation of the cam 14 drives the sliding column 20 to slide on the inner wall of the sliding frame 21, and then cooperates with the limiting effect of the limiting rod 15 to drive the sliding block 16 to move up and down, and indirectly drives the connecting rod 7 to move up and down, so that the magnet 2 36 moves up and down, and further has the following two motion states: First, when the connecting rod 1 7 moves downward, it will simultaneously drive the magnet 2 36 to move downward. The downward movement of the magnet 2 36 will gradually reduce the distance from the magnet 1 10 until the magnet 2 36 and the magnet 1 10 attract each other.

[0026] Second: after magnet 2 36 and magnet 1 10 attract each other, connecting rod 1 7 drives magnet 2 36 to move upward, thereby driving magnet 2 36 to move upward, further pulling the bag filter 9 upward, causing the bag filter 9 to move, thereby driving some dust to fall down, and then as magnet 2 36 and magnet 1 10 rise together, until the bag filter 9 is pulled upward to the maximum limit, magnet 10 cannot rise, and the distance between magnet 2 36 and magnet 1 10 will become farther and farther, until the magnetic attraction between magnet 2 36 and magnet 1 10 is lost, at this time, magnet 10, under the action of gravity, causes the bag filter 9 to fall quickly to its original state, shaking off the dust to complete the dust cleaning.

[0027] The setting of the stretching component allows the magnet 2 36 to move up and down and attract the magnet 1 10 on the bag filter 9, thereby driving the bag filter 9 to move, thereby driving some dust to fall down, and when the bag filter 9 is pulled upward to the maximum limit, the distance between the magnet 2 36 and the magnet 1 10 will become farther and farther, until the magnetic attraction between the magnet 2 36 and the magnet 1 10 is lost, at this time, the magnet 10 under the action of gravity causes the bag filter 9 to fall quickly to its original state, shake off the dust, and thereby improve the effect of cleaning the dust. It is worth noting that, in this embodiment, the gas dry bag filter further includes a twisting assembly, which is also arranged in the dust removal box 4, and includes: A fixing plate 24, the side of which is fixedly connected to the inner wall of the dust removal box 4, a fixing block 23 is fixedly connected to the upper end surface of the fixing plate 24, a limiting rod 25 is fixedly connected to the lower end surface of the fixing block 23, a sleeve 26 is slidably connected to the surface of the limiting rod 25, a straight tooth row 22 is slidably connected to the outer surface of the sleeve 26, a straight tooth row 22 is slidably connected to the tooth surface of the straight tooth row 22, a gear ring 18 is meshedly connected to the tooth surface of the gear ring 18, an inner wall of the gear ring 18 is fixedly connected to the outer surface of the connecting rod 7, a through slot is also provided on the side of the sliding block 16, and a slot wall of the slot is slidably connected to the back tooth surface of the straight tooth row 22.

[0028] In this embodiment, during the up and down movement of the sliding block 16, the sleeve 26 will be driven to slide on the surface of the limiting rod 25 at the same time. Since the limiting rod 25 is inclined, the straight tooth row 22 will be driven to slide on the groove on the sliding block 16, thereby driving the gear ring 18 to rotate, thereby causing the connecting rod 17 to rotate, and further driving the bag filter 9 to twist through the mutually attracted magnets 2 36 and 10, and utilizing the mutual friction of the inner walls of the bag filter 9 to further clean up the dust.

[0029] The twisting assembly is set up, through the rotation of the connecting rod 1 7, the mutually attracted magnets 2 36 and 10 are used to drive the bag filter 9 to twist, and the mutual friction of the inner walls of the bag filter 9 is used to further clean the dust, thereby further improving the dust cleaning effect of the dry bag dust collector and ensuring that the bag filter 9 can be maintained in a state of good permeability.

[0030] Embodiment 2, based on the above embodiment: See also Figure 2 , Figure 4 , Figure 6 , Figure 7 and Figure 8 The gas dry bag dust collector also includes a vibration component, which is arranged in the dust removal box 4 and includes: A rotating disk 34 is provided, the lower end surface of the rotating disk 34 is slidably connected to the upper end surface of the connecting rod 7, a spherical groove is provided on the upper end surface of the rotating disk 34, the groove wall of the spherical groove is rotatably connected to the end spherical curved rod 35, the outer surface of the mounting frame 17 is fixedly connected to a connecting plate 33, the surface of the connecting plate 33 is slidably connected to a limiting rod 32, the upper end surface of the limiting rod 32 is fixedly connected to a baffle 28, and the upper end surface of the baffle 28 is fixedly connected to a vibration motor 29.

[0031] A sliding plate 31 is provided with a spherical groove 2 on its lower end surface, the groove wall of which is rotatably connected to the upper spherical surface of the end spherical curved rod 35, and a through groove is also provided on the upper end surface of the sliding plate 31, the groove wall of which is slidably connected to the surface of a limiting rod 32, and a motion sensor 30 is fixedly connected to the upper end surface of the limiting rod 32, and the motion sensor 30 is used to detect the displacement distance of the sliding plate 31 relative to the baffle 28.

[0032] In this embodiment, the rotation of the connecting rod 7 drives the rotating disk 34 to rotate, and the rotation of the rotating disk 34 drives the end spherical curved rod 35 to revolve around the connecting rod 7 as the axis, thereby driving the sliding plate 31 to slide up and down on the surface of the limit rod 32, so that the sliding plate 31 and the baffle 28 have a relative displacement, and then the displacement between the baffles 28 is detected by the mobile sensor 30. For example, when the distance between the sliding plate 31 and the baffle 28 is set to be greater than 10 cm, the vibration motor 29 vibrates, driving the connecting rod 7 to vibrate, thereby driving the bag filter 9 to vibrate. When the distance between the sliding plate 31 and the baffle 28 is less than 10 cm, the vibration motor 29 stops vibrating, so that the vibration of the bag filter 9 is more irregular, the vibration effect is better, and the dust can be better dropped.

[0033] The setting of the vibration component, through the setting of the indirect start-stop vibration motor 29, makes the vibration of the bag filter 9 more irregular, the vibration effect is better, the dust can be better dropped, and the cleaning effect of the dry bag dust collector is further improved.

[0034] Embodiment 3, based on the above embodiment: See also Figure 1 , Figure 2 and Figure 3 The gas dry bag dust collector also includes a collecting assembly, which is arranged in the air inlet box 2 and includes: The inner walls of the dust outlet pipe 1 and the air inlet box 2 are also provided with a through slot, the slot wall is fixedly connected to the outer surface of the dust outlet pipe 1, and the upper end surface of the dust outlet pipe 1 is fixedly connected with a funnel 37, and the opening end of the funnel 37 is facing the lower end of the bag filter 9.

[0035] In this embodiment, the fallen dust will leak into the funnel 37 and then be discharged into the dry bag dust collector through the dust outlet pipe 1, thereby reducing the accumulation speed of dust inside the dry bag dust collector and improving the ability of the dry bag dust collector to work continuously.

[0036] Working principle: When the gas dry bag dust collector used in the SRV furnace gas purification system is used, it includes the following steps: S1: The gas to be filtered is passed into the air inlet pipe 6, and then enters the air inlet box 2 through the air inlet pipe 6, and then enters the filter box 3 through the bag filter 9. Next, through a pipeline, it is connected to the air outlet pipe 5 to extract the gas in the filter box 3; S2: After long-term use, dust will adhere to the bag filter 9. When the dust needs to be cleaned, the motor 12 is started to drive the magnet 2 36 to move downward until the magnet 2 36 and the magnet 1 10 attract each other. S3: After the magnet 2 36 and the magnet 1 10 attract each other, the connecting rod 1 7 rotates, driving the bag filter 9 to twist, and utilizing the mutual friction of the inner wall of the bag filter 9 to further clean up the dust; S4: At the same time, the connecting rod 1 7 drives the magnet 2 36 to move upward, and pulls the bag filter 9 upward, thereby driving some dust to fall down, until the bag filter 9 is pulled upward to the maximum limit, the magnet 10 cannot rise, and the distance between the magnet 2 36 and the magnet 10 will become farther and farther, until the magnetic attraction between the magnet 2 36 and the magnet 10 is lost, so that the bag filter 9 will quickly fall down and return to its original state under the action of gravity, and shake off the dust; S5: The connecting rod 7 rotates, so that there is a relative displacement between the sliding plate 31 and the baffle 28. The displacement between the baffles 28 is detected by the mobile sensor 30 to control the start and stop of the vibration motor 29, so that the bag filter 9 vibrates. Finally, the fallen dust will leak into the funnel 37 and then be discharged into the dry bag dust collector through the dust outlet pipe 1, thus completing the use of the dry bag dust collector.
