Description

Technical Field

[0001] This invention relates to the field of baghouse dust collector technology, specifically to a high-efficiency baghouse dust collector. Background Technology

[0002] A baghouse dust collector is a dust removal tool used to block and intercept dust particles contained in the smoke produced after the combustion of flammable materials, and to clean the intercepted dust. This helps technicians isolate the smoke and dust produced after the combustion of various flammable substances, release non-toxic and dust-free gases that meet air quality standards, and protect the air environment from damage.

[0003] However, most existing baghouse dust collectors use high-pressure jet cleaning in the dust removal process. While this method can remove dust adhering to the surface of the bag to some extent, the high-pressure gas cannot penetrate deep into the bag due to the limited depth of the bag. As a result, some dust remains stubbornly attached to the bottom of the bag and cannot be completely blown off. Summary of the Invention

The flue gas enters the dust collector body from the dust gas inlet, the clean gas is discharged from the clean gas outlet, and the dust is discharged from the ash discharge port in the middle of the bottom of the dust collector body.

[0007] Preferably, the top perimeter of the mounting hole has multiple sets of fixing slots, and the bottom perimeter of the filter bag frame has multiple sets of insertion posts. The insertion posts are inserted into the fixing slots to fix the filter bag frame in the mounting hole.

[0008] Preferably, the top periphery of the rotating ring is provided with multiple sets of L-shaped connecting rods, and the top periphery of the driven gear is provided with multiple sets of connecting slots. The outer ends of the L-shaped connecting rods are inserted into the connecting slots to connect the rotating ring and the driven gear. The driven gear is connected to the rotating ring, and the rotation of the driven gear can drive the rotating ring to rotate synchronously in the limiting slot provided on the top of the filter bag frame.

[0009] Preferably, the perforated plate has a drive gear in the middle of every four sets of driven gears. The drive gear meshes with the four sets of driven gears around it. When the drive gear rotates, it can drive the four sets of driven gears to rotate synchronously.

[0010] Preferably, four sets of motors are provided on the top of the dust collector body, and a rotating shaft is inserted into the bottom end of the motor. The rotating shaft is inserted into the interior of the dust collector body, and the bottom end of the rotating shaft is connected to the drive gear provided in the middle of each of the four sets of driven gears. The motor can drive the rotating shaft to drive the drive gear to rotate.

[0011] Preferably, the top of the dust collector body is connected to multiple sets of blowpipes, each set of blowpipes is perpendicular to the middle of the mounting holes starting in the same row on the orifice plate, the outer end of the blowpipe is connected to a pulse valve and an air manifold, the part of the blowpipe inserted into the dust collector body is provided with multiple sets of first connecting pipes at the bottom, the first connecting pipes are perpendicular to the center of the mounting holes.

[0012] Preferably, the bottom of the first connecting pipe can be sleeved on the top of the second connecting pipe provided in the middle of the cross support plate to connect the first connecting pipe and the second connecting pipe. A sealing bearing is provided on the outer side of the top of the second connecting pipe, and the sealing bearing rotates and seals the connection between the first connecting pipe and the second connecting pipe.

[0013] Preferably, the outer surface of the blow plate connected to the bottom of the second connecting pipe is provided with multiple sets of high-pressure nozzles. The high-pressure nozzles are aimed at the filter bag fitted on the filter bag frame and can blow the filter bag.

[0014] Compared with the prior art, the beneficial effects of the present invention are: The high-efficiency baghouse dust collector proposed in this invention, when the dust collector body is in operation, dusty gas is introduced into the dust collector body through the dust gas inlet, and then filtered through the filter bags fitted at the bottom of the filter bag frame installed in the perforated plate. The dust is retained at the bottom of the dust collector body and discharged through the ash discharge port opened in the middle of the bottom of the dust collector body. The air purified by the filter bags is discharged through the clean air outlet on one side of the top of the dust collector body. After the dust collector body has been running for a period of time, the motor installed at the top of the dust collector body is started, which drives the drive shaft to rotate the drive gear connected at the bottom of the shaft. At this time, the drive gear meshes with the driven gears around the drive gear, driving the driven gears to rotate synchronously. While the driven gears are rotating, they pass through the L-shaped connecting rod inserted into the connecting slot. The rotating ring begins to rotate within the limiting slot at the top of the filter bag frame. This rotation causes the blow plate, connected to the bottom of the second connecting pipe inserted in the middle of the cross support plate, to move in a circular motion around the filter bag fitted at the bottom of the filter bag frame. Then, by activating the pulse valve connected to the outer end of the blow pipe, gas from the air tank at the top of the blow pipe is introduced into the blow pipe. The blow pipe then passes through the first connecting pipe at its bottom to the second connecting pipe, which in turn passes the gas into the blow plate connected at its bottom. This causes the high-pressure nozzles on the outer surface of the blow plate to spray air in a circular motion onto the filter bag, cleaning it and preventing dust from adhering to the bag, thus reducing its filtration efficiency and accuracy.

[0019] A dust inlet 2 is provided on one side of the bottom of the dust collector body 1, and a clean air outlet 3 is provided on one side of the top of the dust collector body 1. The flue gas enters the dust collector body 1 through the dust inlet 2, and the clean air is discharged from the clean air outlet 3.

Multiple sets of fixing slots 18 are provided around the top of the mounting hole, and multiple sets of insertion posts 19 are provided around the bottom of the filter bag frame 10. The insertion posts 19 are inserted into the fixing slots 18 to fix the filter bag frame 10 in the mounting hole. The dust gas enters the dust collector body 1 through the dust inlet 2, and then is filtered by the filter bag 16 installed at the bottom of the filter bag frame 10 installed in the perforated plate 5. The dust is left at the bottom of the dust collector body 1 and discharged through the ash discharge port in the middle of the bottom of the dust collector body 1. The air purified by the filter bag 16 is discharged through the clean air outlet 3 on one side of the top of the dust collector body 1.

[0020] Multiple sets of L-shaped connecting rods 21 are provided around the top of the rotating ring 12, and multiple sets of connecting slots 20 are provided around the top of the driven gear 11. The outer ends of the L-shaped connecting rods 21 are inserted into the connecting slots 20 to connect the rotating ring 12 and the driven gear 11. The driven gear 11 is connected to the rotating ring 12. The rotation of the driven gear 11 can drive the rotating ring 12 to rotate synchronously in the limiting slot 17 opened at the top of the filter bag frame 10. The perforated plate 5 is provided with a drive gear 9 in the middle of every four sets of driven gears 11. The drive gear 9 meshes with the four sets of driven gears 11 around it. When the drive gear 9 rotates, it can drive the four sets of driven gears 11 to rotate synchronously. The rotation of the drive gear 9 meshes with the driven gears 11 around it, driving the driven gears 11 to rotate synchronously. When the driven gear 11 rotates, it starts to drive the rotating ring 12 to rotate in the limiting slot 17 opened at the top of the filter bag frame 10 through the L-shaped connecting rods 21 inserted in the connecting slots 20.

[0021] Four sets of motors 7 are installed on the top of the dust collector body 1. The bottom end of each motor 7 is connected to a rotating shaft 8, which is inserted into the interior of the dust collector body 1. The bottom end of the rotating shaft 8 is connected to a drive gear 9 located in the middle of each of the four sets of driven gears 11. The motors 7 can drive the rotating shaft 8 to rotate the drive gear 9. Multiple sets of blowpipes 4 are inserted at the top of the dust collector body 1. Each set of blowpipes 4 is perpendicular to the middle of the mounting holes starting in the same row on the orifice plate 5. The outer end of the blowpipe 4 is connected to a pulse valve and an air tank. The part of the blowpipe 4 inserted into the interior of the dust collector body 1 has multiple sets of first connecting pipes 6 at the bottom. The first connecting pipes 6 are perpendicular to the center of the mounting holes. When the pulse valve connected to the outer end of the blowpipe 4 is activated, the gas in the air tank at the top of the outer side of the blowpipe 4 is introduced into the blowpipe 4. The blowpipe 4 then introduces the gas into the second connecting pipe 14 through the first connecting pipe 6 at the bottom. The second connecting pipe 14 then introduces the gas into the blowpipe plate 15 connected to the bottom of the second connecting pipe 14.

[0022] The bottom of the first connecting pipe 6 can be fitted onto the top of the second connecting pipe 14 located in the middle of the cross support plate 13, connecting the first connecting pipe 6 and the second connecting pipe 14. A sealing bearing 22 is provided on the outer side of the top of the second connecting pipe 14, which provides a rotational seal for the connection between the first connecting pipe 6 and the second connecting pipe 14. The outer surface of the blow plate 15 connected to the bottom of the second connecting pipe 14 is provided with multiple sets of high-pressure nozzles 23. The high-pressure nozzles 23 are aimed at the filter bag 16 fitted on the filter bag frame 10, and can blow air onto the filter bag 16. The high-pressure nozzles 23 on the outer surface of the blow plate 15 start to blow air, and blow air around the filter bag 16 to clean the filter bag 16, so as to prevent dust from adhering to the filter bag 16 and reducing the filtration efficiency and filtration accuracy of the filter bag 16.

[0023] In actual use, when the dust collector body 1 is running, dusty gas enters the dust collector body 1 through the dust inlet 2, and then is filtered by the filter bags 16 fitted at the bottom of the filter bag frame 10 installed in the perforated plate 5. The dust is retained at the bottom of the dust collector body 1 and discharged through the ash discharge port opened in the middle of the bottom of the dust collector body 1. The air purified by the filter bags 16 is discharged through the clean air outlet 3 on one side of the top of the dust collector body 1. After the dust collector body 1 has been running for a period of time, the motor 7 installed at the top of the dust collector body 1 is started, which drives the rotating shaft 8 to rotate the drive gear 9 connected at the bottom of the rotating shaft 8. At this time, the drive gear 9 rotates and meshes with the driven gears 11 around the drive gear 9, causing the driven gears 11 to rotate synchronously. While the driven gears 11 are rotating, they start to drive the rotating ring 12 to rotate in the limiting slot 17 opened at the top of the filter bag frame 10 through the L-shaped connecting rod 21 inserted in the connecting slot 20. The rotating ring 12 rotates and drives the second connecting pipe 1 inserted in the middle of the cross support plate 13. The bottom-connected blow plate 15 rotates in a circular motion around the filter bag 16 fitted at the bottom of the filter bag frame 10. Then, by activating the pulse valve connected to the outer end of the blow pipe 4, gas from the air bag at the top of the outer side of the blow pipe 4 is introduced into the blow pipe 4. The blow pipe 4 then introduces gas into the second connecting pipe 14 through the first connecting pipe 6 at the bottom. The second connecting pipe 14 then introduces gas into the blow plate 15 connected to the bottom of the second connecting pipe 14, causing the high-pressure nozzles 23 on the outer surface of the blow plate 15 to start spraying gas, performing circumferential spraying on the filter bag 16 to clean the filter bag 16 and prevent dust from adhering to the filter bag 16, reducing the filtration efficiency and filtration accuracy of the filter bag 16. Furthermore, the second connecting pipe 14 is provided with a sealing bearing 22 at the connection with the first connecting pipe 6. The sealing bearing 22 seals the connection between the first connecting pipe 6 and the second connecting pipe 14 while preventing the first connecting pipe 6 from obstructing the rotation of the second connecting pipe 14, thus preventing the driven gear 11 from driving the rotating ring 12 to rotate normally.
