Description

Technical Field

[0001] This utility model belongs to the field of blast furnace technology, specifically a quick-connect mechanism for a bag filter dust collector. Background Technology

[0002] A blast furnace is a furnace equipment that uses steel plates as its shell to withstand extremely high temperatures for steelmaking. During steelmaking, it also generates a large amount of flue gas, which is discharged from the exhaust pipe at the top of the blast furnace to a bag filter and other flue gas treatment equipment for filtration and purification.

[0003] Among them, a search revealed application number CN202221248803.5, a bag filter dust collector for easy disassembly. This bag filter dust collector features a mechanism where a starting motor output shaft rotates a gear-driven rack to move sealing plates forward on a slide rail. Due to the opening in the square groove, after the first sealing plate is moved out of the dust collector housing, it automatically engages with the rack inside the square groove of the second sealing plate until all sealing plates are removed from the dust collector housing. The user can then easily separate the filter bags from the sealing plates in an open environment, thus achieving the purpose of easy disassembly of the dust collector filter bags. However, the following shortcomings exist:

[0004] When workers use this type of easily disassembled baghouse dust collector to install and process the filter bags, the motor is started to rotate the gear-driven rack and pinion, which moves the sealing plate forward on the slide rail. After the first sealing plate is moved out of the dust collector housing, it will automatically engage the rack and pinion inside the square groove of the second sealing plate until all the sealing plates are moved out of the dust collector housing. However, when the motor rotates the gear-driven rack and pinion to move the sealing plates and disassemble or install several filter bags and filter cages, all the filter bags and filter cages are disassembled at the same time. This means that if workers only need to maintain a few filter bags and filter cages, all the filter bags and filter cages need to be disassembled at the same time, which is slightly inconvenient when workers only need to disassemble or install one filter bag or filter cage. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that the above-mentioned bag dust collector is slightly inconvenient when only one bag or bag cage needs to be disassembled or installed, and to provide a quick-connect mechanism for the bag dust collector.

A damping telescopic rod A is fixedly installed between the upper two sides of the limiting card holder A and the upper two sides of the inner wall of the limiting frame A, with a spring fitted to the outer side of the damping telescopic rod A.

[0008] The limiting and clamping disassembly mechanism comprises a sliding groove B, a limiting slot, a limiting frame B, a limiting bracket B, a damping telescopic rod B, a sliding groove C, a damping telescopic rod C, and a limiting clamping frame. Sliding grooves B are embedded on both sides of the support frame A. A limiting frame B is slidably mounted on the side inside the sliding groove B.

[0010] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0011] 1. The quick-connect mechanism of the bag filter in this type of blast furnace bag dust collector, through the setting of a limiting disassembly and assembly mechanism, allows the operator to use the cooperation between the slide groove A, the limiting groove, the slot, the limiting frame A, the limiting clamp A, and the damping telescopic rod A. The limiting frame A slides freely between the slide groove A and the inner side of the limiting groove, and the limiting clamp A slides freely inside the slot through the damping telescopic rod A and the outer spring to engage and limit the position.

[0012] 2. The quick-connect mechanism of the bag filter in this type of steelmaking blast furnace bag dust collector is equipped with a limiting and pressing disassembly mechanism. This allows the operator to quickly disassemble and replace the bag by means of the cooperation between the slide groove B, the limiting slot, the limiting frame B, the limiting bracket B, the damping telescopic rod B, the slide groove C, the damping telescopic rod C, and the limiting pressure frame. The limiting frame B slides freely inside the slide groove B, and the limiting bracket B slides freely inside the limiting slot through the damping telescopic rod B and the outer spring.

[0013] 3. The quick-connect mechanism of the bag filter in this type of blast furnace bag dust collector features a shaking cleaning mechanism. This mechanism, through the coordination of the support frame B, telescopic rod, servo motor, and eccentric wheel, utilizes the servo motor to drive the eccentric wheel to rotate rapidly. This continuously strikes the grid frame, which is then repeatedly extended and retracted by the telescopic rod and outer spring. Simultaneously, the grid frame shakes rapidly, constantly colliding with the filter bags to create a shaking effect. This improves the efficiency of cleaning dust from the filter bag surface, making the bag surface easier to clean, reducing bag maintenance, and simplifying subsequent bag upkeep.

Detailed Implementation

[0020] 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.

[0021] Example 1: Refer to Figure 1-4 A quick-connect mechanism for a bag filter dust collector includes a bag filter dust collector 1, a flue gas pipe 101, a dust discharge port 102, a waste bin 103, a baffle 104, an air compressor 105, a pulse solenoid valve 106, a jet pipe 107, a jet head 108, an exhaust pipe 109, an exhaust fan 1091, an air guide frame 2, a mounting groove A201, a support frame A202, a grid frame 205, a mounting groove B209, and a filter bag 4. The flue gas pipe 101 is embedded on both sides of the bag filter dust collector 1, and a blast furnace exhaust pipe is provided at the other end of the flue gas pipe 101. The bag filter 1 has a dust discharge port 102 embedded at its lower part. A waste bin 103 is located below the dust discharge port 102. An exhaust duct 109 is embedded above the bag filter 1, with a desulfurization and denitrification tower installed at the other end. An exhaust fan 1091 is installed inside the lower part of the exhaust duct 109. An air compressor 105 is located on the side inside the bag filter 1. A pulse solenoid valve 106 is embedded above the bag filter 1, near the air compressor 105. The air compressor 105 and the pulse solenoid valve... The solenoid valves 106 are connected by air guide pipes. A jet pipe 107 is embedded above each pulse solenoid valve 106, with the other end of the jet pipe 107 extending into the upper part of the bag filter 1. Several jet nozzles 108 are embedded below the jet pipe 107, arranged equidistantly. A baffle 104 is fixedly installed in the upper part of the bag filter 1. An air guide frame 2 is embedded below the baffle 104. A mounting groove A201 is embedded below the air guide frame 2, and the mounting groove A201 is annular in shape. A support frame A202 is slidably installed inside the lower part of the 01. A grid frame 205 is installed below the support frame A202. An installation groove B209 is embedded below the support frame A202. A cloth bag 4 is slidably installed inside the lower part of the installation groove B209 near the outside of the grid frame 205. A limiting and disassembly mechanism for easy disassembly and maintenance of the grid frame is installed inside the lower part of the air guide frame 2. A limiting and pressing disassembly mechanism for easy disassembly and replacement of the cloth bag is installed inside the lower part of the support frame A202. A shaking dust cleaning mechanism for efficient dust removal is installed below the support frame A202.

[0022] Reference Figure 2-3Furthermore, the limiting assembly and disassembly mechanism consists of a slide groove A206, a limiting groove 207, a card slot 208, a limiting frame A5, a limiting card frame A501, and a damping telescopic rod A502.

[0023] The air guide frame 2 has sliding grooves A206 embedded on both sides. The support frame A202 has limiting grooves 207 embedded on both sides near the sliding grooves A206. A limiting frame A5 is slidably installed between the limiting grooves 207 and the inner sides of the sliding grooves A206. A limiting bracket A501 is slidably installed inside the limiting bracket A5, with one lower corner of the limiting bracket A501 inclined. A slot 208 is embedded in the lower inner wall of the limiting groove 207, with the inner wall of the slot 208 inclined. The lower part of the limiting bracket A501 is slidably fitted inside the slot 208. Damping telescopic rods A502 are fixedly installed between the upper two sides of the limiting bracket A501 and the upper two sides of the inner wall of the limiting frame A5. Springs are fitted to the outer sides of the damping telescopic rods A502. When workers need to install several grid frames 205 and filter bags 4, they open the front door panel of the bag filter dust collector 1. After sliding one of the grid frames 205 with filter bags 4 installed into the lower part of one of the installation slots A201, the workers push the two limiting brackets A5 into the inner sides of the sliding groove A206 and the limiting groove 207 respectively. Simultaneously, they squeeze the limiting bracket A501, causing the damping telescopic rod A502 and the outer spring to retract. This brings the limiting bracket A501 close to the slot 208, after which the damping telescopic rod A502 and the outer spring pop out and slide the limiting bracket A501 into the slot 208, completing the installation of one of the grid frames 205 with filter bags 4. The workers then use the same method to install the other grid frames with filter bags 4. After the frame 205 is installed, the workers close the door panel in front of the bag filter 1. During blast furnace steelmaking, a large amount of flue gas is discharged into the associated flue gas pipe. Simultaneously, the flue gas from the blast furnace's flue gas pipe is drawn into the bag filter 1 via the associated fan and then into the flue gas pipe 101. At the same time, the exhaust fan 1091 is turned on, forcing the flue gas through several filter bags 4 to filter the dust particles carried in the flue gas. The flue gas is then drawn into the exhaust pipe 109 from the guide frame 2 and discharged into other desulfurization and denitrification towers for further treatment. Afterwards, the workers turn on the air compressor 105 and the pulse solenoid valve 106, spraying compressed air through the jet pipe 107 from several jet nozzles 108 onto the filter bags 4. This causes the filter bags 4 to shake, dislodging surface dust that falls through the dust discharge port 102 into the waste bin 10. 3. For internal collection and processing, and when staff need to periodically disassemble the entire grid frame 205 for maintenance, push the two opposing limit frames A5 upwards so that the inner side limit brackets A501 slide out of the slots 208, causing the damping telescopic rod A502 and the outer spring to retract. After releasing the limit frame A5, the staff pushes the limit frame A5 to slide out of the slide grooves A206 and limit slots 207. After releasing the support frame A202, the staff pushes the grid frame 205 to drive the support frame A202 to slide out of the mounting slots A201 to complete the disassembly. After this, the other grid frames 205 are disassembled in the same way, and after maintenance, they are quickly reinstalled in the same way. This facilitates the staff's quick disassembly and maintenance of the entire grid frame 205.This ensures that the overall assembly and disassembly of several grid frames 205 will not waste excessive time and negatively impact the blast furnace's operational efficiency.

[0024] Reference Figure 2-4 Furthermore, the limiting and pressing disassembly mechanism is composed of a slide groove B6, a limiting slot 601, a limiting frame B7, a limiting frame B701, a damping telescopic rod B702, a slide groove C703, a damping telescopic rod C704, and a limiting pressure frame 705.

[0025] Support frame A202 has sliding grooves B6 embedded on both sides. A limit frame B7 is slidably mounted inside the sliding groove B6. A limit bracket B701 is slidably mounted above and below the inner side of the limit bracket B7, with one corner of each limit bracket B701 being inclined. A damping telescopic rod B702 is fixedly installed between the two opposite sides of the limit bracket B701, and a spring is fitted to the outer side of the damping telescopic rod B702. Limit slots 601 are embedded in the inner wall of the sliding groove B6, with the inner wall of the limit slot 601 being inclined. The limit bracket B701 is slidably mounted inside the limit slot 601. A sliding groove C70 is embedded in the side of the limit frame B7. 3. A limiting bracket 705 is slidably installed on the inner side of the slide groove C703. The limiting bracket 705 is arc-shaped, and both the arc-shaped concave surface of the limiting bracket 705 and the inner ring of the mounting groove B209 are wavy. A damping telescopic rod C704 is fixedly installed between the side of the limiting bracket 705 and the inner wall of the slide groove C703. A spring is provided on the outer side of the damping telescopic rod C704. When the staff disassembles the grid frame 205 for maintenance, if the surface of the cloth bag 4 is damaged and needs to be removed and replaced, the staff pushes the opposing limiting brackets B701 on the sides of the two limiting brackets B7 to slide out of the limiting slot 601, causing the damping telescopic rod B702 and the outer spring to retract. After releasing the limiting bracket B7, the worker pushes the limiting bracket B7 to slide in opposite directions inside the slide groove B6, causing the damping telescopic rod C704 and the outer spring to unfold, and causing the limiting pressure bracket 705 to open in the opposite direction. After releasing the cloth bag 4, the worker pushes the cloth bag 4 to slide the bag opening out of the mounting groove B209. Then, a new cloth bag 4 is placed on the outside of the grid frame 205, and the bag opening of the cloth bag 4 slides into the mounting groove B209. The worker then pushes the two limiting brackets B7 to slide in opposite directions inside the slide groove B6, squeezing the limiting bracket B701 to contract the damping telescopic rod B702 and the outer spring, causing the limiting bracket B701 to approach the limiting position. After the card slot 601 is opened, the damping telescopic rod B702 and the outer spring pop out and slide the limiting card holder B701 into the inner side of the limiting card slot 601 to limit and fix the limiting frame B7. At the same time, it drives the corresponding limiting pressure frame 705 and the inner wavy surface of the mounting groove B209 to fit and contact each other. After the two limiting pressure frames 705 come into contact with each other, they squeeze and limit the bag opening of the cloth bag 4 between the limiting pressure frame 705 and the inner wall of the mounting groove B209. This causes the damping telescopic rod C704 and the outer spring to retract, so that the retracted damping telescopic rod C704 and the outer spring generate a counter-pushing force on the limiting pressure frame 705, thus completing the replacement of the cloth bag 4. This facilitates the quick disassembly and replacement of the cloth bag 4 by the staff.

[0026] Reference Figure 2-3 Furthermore, the shaking dust removal mechanism consists of a support frame B203, a telescopic rod 204, a servo motor 3, and an eccentric wheel 301;

[0027] Support frame B203 is fixedly installed below support frame A202. Telescopic rods 204 are fixedly installed between the two sides of support frame B203 and the two sides of the inner ring of grid frame 205, and springs are provided on the outer side of telescopic rods 204. Servo motor 3 is fixedly installed inside the lower part of support frame B203. Servo motor 3 is connected to eccentric wheel 301 through output shaft. When the operator uses the blast furnace for steelmaking, a large amount of flue gas will be generated and discharged into the matching flue gas pipe. At the same time, the flue gas in the blast furnace matching flue gas pipe is discharged into flue gas pipe 101 and guided into bag dust collector 1 by the matching fan. At the same time, the exhaust fan 1091 is turned on to make the flue gas pass through several filter bags 4. After filtering the dust particles carried in the flue gas, it is drawn into the exhaust pipe 109 from the guide frame 2 and discharged into other desulfurization and denitrification towers for treatment. The dust on the surface of filter bags 4 needs to be cleaned regularly. At the same time, the staff turns on the air compressor 105 and the pulse solenoid valve 106, and sprays compressed air through the jet pipe 107 from several jet nozzles 108 onto the filter bag 4, causing the filter bag 4 to shake and shake off the surface dust. At the same time, the staff turns on the servo motor 3 to drive the eccentric wheel 301 to rotate rapidly, and continuously hit the grid frame 205. Through the telescopic rod 204 and the outer spring, the grid frame 205 is repeatedly extended and retracted, causing the grid frame 205 to shake rapidly. At the same time, it continuously collides with the filter bag 4 to shake, causing the filter bag 4 to shake at a higher frequency, and quickly shake off the surface dust, which falls through the dust discharge port 102 into the waste bin 103 for collection and treatment. This improves the efficiency of cleaning the dust on the surface of the filter bag 4, makes the surface of the filter bag 4 easier to clean, reduces the maintenance of the filter bag 4, and makes subsequent maintenance of the filter bag 4 easier.

[0028] Reference Figure 1-3 Furthermore, the air compressor 105, pulse solenoid valve 106, exhaust fan 1091, and servo motor 3 are all electrically connected to an external power source through the control panel of the bag filter 1.

[0029] Example 2: Figure 3 , 5As shown, in addition to the embodiment in which a limiting bracket A501 is slidably disposed on the inner side of the limiting bracket A5, and one lower corner of the limiting bracket A501 is inclined, and a slot 208 is embedded in the lower part of the inner wall of the limiting groove 207, and the inner wall of the slot 208 is inclined, and the limiting bracket A501 is slidably disposed on the lower part of the slot 208, another embodiment exists where the limiting bracket A501 is slidably disposed on the inner side of the limiting bracket A5, and one lower corner of the limiting bracket A501 is arc-shaped, and a slot 208 is embedded in the lower part of the inner wall of the limiting groove 207, and the inner wall of the slot 208 is arc-shaped. The limiting bracket A501 is slidably fitted inside the slot 208. When the worker pushes the two limiting brackets A5 into the slots A206 and 207 respectively, the limiting bracket A501, which has an arc-shaped corner, has a larger slope. This allows the limiting bracket A501 to be squeezed more easily, causing the damping telescopic rod A502 and the outer spring to retract. After the limiting bracket A501 approaches the slot 208, the damping telescopic rod A502 and the outer spring pop out and slide the limiting bracket A501 into the slot 208, completing the installation of one of the grid frames 205 with the cloth bag 4. Compared with the first embodiment, the installation is easier and more convenient.

[0030] Working principle: First, when the operator needs to install several grid frames 205 and filter bags 4, they open the front door panel of the bag filter dust collector 1. After sliding one of the grid frames 205 with filter bags 4 installed into the lower part of one of the installation slots A201, the operator pushes two limiting brackets A5 into the inner sides of the sliding groove A206 and the limiting groove 207 respectively. Simultaneously, the operator squeezes the limiting bracket A501, causing the damping telescopic rod A502 and the outer spring to retract. This brings the limiting bracket A501 close to the slot 208. Then, the damping telescopic rod A502 and the outer spring pop out, allowing the limiting bracket A501 to slide into the slot 208, completing the installation of one of the grid frames 205 with filter bags 4. The operator then repeats the same process for the other grid frames 205 with filter bags 4 installed. After the grid frame 205 of the filter bag 4 is installed, the staff closes the door panel in front of the bag filter 1. During blast furnace steelmaking, a large amount of flue gas is discharged into the associated flue gas pipe. Simultaneously, the flue gas from the blast furnace's flue gas pipe is discharged into the flue gas pipe 101 and guided into the bag filter 1 by the associated fan. At the same time, the exhaust fan 1091 is turned on, forcing the flue gas through several filter bags 4 to filter out dust particles. The flue gas is then drawn into the exhaust pipe 109 from the guide frame 2 and discharged into other desulfurization and denitrification towers for treatment. Afterwards, the staff turns on the air compressor 105 and the pulse solenoid valve 106, spraying compressed air through the jet pipe 107 from several jet nozzles 108 onto the filter bags 4, causing the filter bags 4 to shake. Simultaneously, the staff turns on the servo motor 3. The eccentric wheel 301 rotates rapidly, constantly striking the grid frame 205. Through the telescopic rod 204 and the outer spring, the grid frame 205 repeatedly extends and retracts, causing it to shake rapidly. Simultaneously, it continuously collides with the cloth bag 4, causing it to shake even more frequently, quickly shaking off surface dust that falls through the dust outlet 102 into the waste bin 103 for collection and processing. Then, when workers need to periodically disassemble the grid frame 205 for maintenance, they push the two opposing limit frames A5 upwards, causing the inner side limit brackets A501 to slide out of the slot 208. This causes the damping telescopic rod A502 and the outer spring to retract. After releasing the limit frame A5, the workers push the limit frame A5 out of the slide groove A206 and the limit slot 207, and release the support frame A202. After the staff pushes the grid frame 205 to slide the support frame A202 out of the mounting slot A201 to complete the disassembly, the other grid frames 205 are disassembled in the same way. Finally, if the surface of the cloth bag 4 is damaged and needs to be disassembled and replaced, the staff pushes the two limit frames B7 and the opposite limit brackets B701 on the sides to slide out of the limit bracket slot 601, causing the damping telescopic rod B702 and the outer spring to retract. After releasing the limit frame B7, the staff pushes the limit frame B7 to slide in the opposite direction inside the slide groove B6, causing the damping telescopic rod C704 and the outer spring to unfold, and causing the limit pressure frame 705 to open in the opposite direction. After releasing the cloth bag 4, the staff pushes the cloth bag 4 to slide the bag opening out of the mounting slot B209.Next, the new cloth bag 4 is placed over the outside of the grid frame 205, and the opening of the cloth bag 4 is slid into the mounting groove B209. Then, the worker pushes the two limiting brackets B7 to slide in opposite directions inside the slide groove B6, squeezing the limiting bracket B701, which causes the damping telescopic rod B702 and the outer spring to retract. After the limiting bracket B701 approaches the limiting slot 601, the damping telescopic rod B702 and the outer spring pop out of the limiting bracket B701 and slide into the limiting slot 601, limiting and fixing the limiting bracket B7. At the same time, it drives the opposite limiting pressure bracket. The inner wavy surface of the mounting groove B209 and the 705 make contact with each other, and after the two limiting pressure frames 705 come into contact with each other, the opening of the cloth bag 4 is squeezed and limited between the limiting pressure frame 705 and the inner wall of the mounting groove B209. This causes the damping telescopic rod C704 and the outer spring to retract, so that the retracted damping telescopic rod C704 and the outer spring generate a counter-pushing force on the limiting pressure frame 705, completing the replacement of the cloth bag 4.
