[0002] With the rapid development of industry, environmental protection requirements are becoming increasingly stringent, and the demand for waste gas treatment equipment from various industrial enterprises is also growing. Bag dust collectors, as one of the important equipment, are widely used in dust collection and purification in cement, steel, electricity, chemical and other industries. It uses fiber-woven filter bags to capture particulate matter in dust-laden gases to achieve the purpose of purifying the air.

[0003] Existing bag-type dust removal devices are usually equipped with a pulse backflush system to periodically remove the dust layer attached to the surface of the bags and maintain a certain filtration efficiency. However, as time goes by, the bags will fail due to wear, aging or clogging, and new bags need to be replaced to ensure the dust removal effect. Traditional bag-type dust removal equipment must be shut down when the bags need to be replaced, and usually part of the structure needs to be disassembled to access the bags for replacement.

[0040] See also Fig.10 and Fig.11As shown, the discharge mechanism includes a storage barrel 2001, a barrel cover 2002, a support plate 2003, a second cylinder 2004 and a pusher rack 2005; a storage barrel 2001 for storing new cloth bags 3 is installed on the upper right side of the connecting frame 15; a barrel cover 2002 is placed on the top of the storage barrel 2001; a support plate 2003 is installed on the lower right side of the connecting frame 15, and the support plate 2003 is located below the storage barrel 2001; a second cylinder 2004 is arranged on the top of the support plate 2003, and a pusher rack 2005 is connected to the telescopic rod of the second cylinder 2004, and a semi-ring structure is provided on the left side of the pusher rack 2005, and the semi-ring structure is used for the new cloth bags 3 in the storage barrel 2001 to fall, and the pusher rack 2005 is used to push the new cloth bags 3 dropped in the storage barrel 2001 onto the first baffle 12.

[0041] When in use, lift the barrel cover 2002, and then stack the new cloth bags 3 that have been compressed appropriately and load them into the storage barrel 2001, so that the new cloth bags 3 at the bottom fall on the top of the support plate 2003, and the new cloth bags 3 at the bottom are in the semi-ring structure of the push rack 2005, then put the barrel cover 2002 back to its original position, and then send the exhaust gas into the shell 1 through the air inlet pipe 101, so that the cloth bags 3 in the shell 1 filter the exhaust gas, and the filtered exhaust gas is discharged from the exhaust pipe 102, and the dust particles filtered out of the exhaust gas fall down to the dust accumulation device 5 for collection, so that the exhaust gas can be filtered;

[0042] When it is necessary to replace the designated cloth bag 3 in the shell 1, the designated electromagnet 9 is energized so that the designated electromagnet 9 is adsorbed on the top of the iron plate 7 by magnetic force, and then the first servo motor 1001 drives the first screw rod 1002 to rotate, so that the first screw rod 1002 drives the iron plate 7 and the designated electromagnet 9 to move downward, thereby stretching and deforming the designated bellows 8 until the top surface of the iron plate 7 drops below the bottom height of the air inlet pipe 101. In this way, the designated cloth bag 3 can be isolated by the designated bellows 8, so that the designated cloth bag 3 stops filtering the exhaust gas, while the other cloth bags 3 continue to filter the exhaust gas, and then the connecting frame 15 is driven to move to the designated position by the mobile platform 14, so that the connecting frame 15 is in the positive position of the designated through hole 11. The first electric push rod 1701 is used to push the first baffle 12 in the designated through hole 11 to the top of the designated cloth bag 3, and then the telescopic rod of the first electric push rod 16 is controlled to extend. When the telescopic rod of the first electric push rod 16 contacts the first baffle 12 in the designated through hole 11, the telescopic rod of the first electric push rod 16 squeezes the first baffle 12 to rotate open, and the first elastic piece 13 is deformed until the telescopic rod of the first electric push rod 16 squeezes the first baffle 12 to completely rotate open, and then the third electric push rod 1702 and the electric clamp 1703 are driven to move downward by the second electric push rod 1701 until the electric clamp 1703 contacts the top surface of the partition 2, and then the electric clamp 1703 is driven to move to the side close to the designated cloth bag 3 by the third electric push rod 1702 until The electric clamp 1703 contacts the cage 4 on the designated cloth bag 3, and then controls the electric clamp 1703 to clamp the cage 4, and then drives the third electric push rod 1702 and the electric clamp 1703 to move upward and reset through the second electric push rod 1701, so that the electric clamp 1703 clamps the cage 4 and moves upward, and makes the top of the cage 4 exceed the height of the fourth electric push rod 1801 on the lower side, and then drives the connecting frame 1802, the brushless motor 1803 and the rubber sleeve 1804 to move to the side close to the cage 4 through the fourth electric push rod 1801 on the lower side, until the rubber sleeve 1804 on the lower side clamps the cage 4, and then controls the electric clamp 1703 to release the cage 4, and then drives the electric clamp 1703 to move and reset through the third electric push rod 1702, and then The brushless motor 1803 on the lower side drives the rubber sleeve 1804 to rotate, so that the rubber sleeve 1804 on the lower side drives the cage 4 to be transported upward by friction, so that the cage 4 is separated from the designated cloth bag 3. When the cage 4 moves upward to a height exceeding the fourth electric push rod 1801 on the upper side, the fourth electric push rod 1801 on the upper side drives the connecting frame 1802, the brushless motor 1803 and the rubber sleeve 1804 to move toward the side close to the cage 4 until the rubber sleeve 1804 on the upper side clamps the cage 4. At the same time, the brushless motor 1803 on the upper side drives the rubber sleeve 1804 to rotate, so that the rubber sleeve 1804 on the upper side also drives the cage 4 to be transported upward by friction. When the cage 4 is transported upward to be separated from the rubber sleeve 1804 on the lower side,The fourth electric push rod 1801 on the lower side drives the connecting frame 1802, the brushless motor 1803 and the rubber sleeve 1804 to move and reset, and the brushless motor 1803 on the lower side drives the rubber sleeve 1804 to stop rotating. When the cage 4 moves upward to a height exceeding the electric clamp 1703 and close to the height of the bottom of the upper rubber sleeve 1804, the brushless motor 1803 on the upper side drives the rubber sleeve 1804 to stop rotating, so that the cage 4 stops moving upward, and then the third electric push rod 1702 and the electric clamp 1703 are driven downward by the second electric push rod 1701 again until the electric clamp 1703 contacts the top surface of the partition 2, and then the third electric push rod 1702 drives the electric clamp 1703 to approach the specified height. The cloth bag 3 moves to one side until the electric clamp 1703 contacts the designated cloth bag 3, and then the electric clamp 1703 is controlled to clamp the designated cloth bag 3, and then the third electric push rod 1702 and the electric clamp 1703 are driven to move upward and reset by the second electric push rod 1701, so that the electric clamp 1703 clamps the designated cloth bag 3 and moves upward, and then the second servo motor 1907 drives the second screw rod 1908 to rotate. Since the first reduction motor 1910 has a self-locking function, the output shaft of the first reduction motor 1910 can use the gear 1911 to limit the rotation of the rotating block 1906 and the winding frame 1909, and as the second screw rod 1908 rotates, the second screw rod 1908 can drive the winding frame 1909 to move backward until the cloth bag 3 is moved upward. The reel 1909 pierces the designated cloth bag 3 with the pointed end at the rear side, then controls the electric clamp 1703 to release the designated cloth bag 3, and then drives the electric clamp 1703 to move and reset through the third electric push rod 1702, and then drives the rotating block 1906 and the reel 1909 to rotate through the first reduction motor 1910 using the gear 1911, so that the reel 1909 drives the designated cloth bag 3 to rotate and rewind. Since the second servo motor 1907 does not have a self-locking function, the reel 1909 will drive the second screw rod 1908 to rotate synchronously when rotating, and the synchronous rotation of the reel 1909 and the second screw rod 1908 can prevent the reel 1909 from moving, and the reel 1909 will rotate the designated cloth bag 3. After the bag 3 completes the rotation and winding, the first reduction motor 1910 uses the gear 1911 to drive the rotating block 1906 and the winding frame 1909 to stop rotating, and then the first cylinder 1904 drives the fixed frame 1905, the rotating block 1906 and the winding frame 1909 to move to the left, so that the winding frame 1909 drives the wound designated cloth bag 3 to move to the left. When the wound designated cloth bag 3 contacts the second baffle 1902, the winding frame 1909 will drive the wound designated cloth bag 3 to squeeze the second baffle 1902 to rotate and open, and the second elastic piece 1903 will be deformed. When the wound designated cloth bag 3 is separated from the second baffle 1902, the second elastic piece 1903 returns to its original state, and the second elastic piece 1903 will drive the second baffle 1902 to reverse and close.After the winding rack 1909 brings the wound designated cloth bag 3 into the storage frame 1901, the second servo motor 1907 drives the second screw rod 1908 to reverse and reset. Since the first reduction motor 1910 has a self-locking function, the output shaft of the first reduction motor 1910 can use the gear 1911 to limit the rotation of the rotating block 1906 and the winding rack 1909. As the second screw rod 1908 reverses and resets, the second screw rod 1908 can drive the winding rack 1909 to move forward and reset, so that the winding rack 1909 is pulled out from the wound designated cloth bag 3 and the wound designated cloth bag 3 stays in the storage frame 1901 for collection. In this way, the old cloth bag 3 can be automatically taken out;

[0043] Then, the first cylinder 1904 drives the fixed frame 1905, the rotating block 1906 and the winding frame 1909 to move right and reset. When the winding frame 1909 contacts the second baffle 1902, the winding frame 1909 will squeeze the second baffle 1902 to reverse and open, and the second elastic sheet 1903 will be deformed. When the winding frame 1909 is separated from the second baffle 1902, the second elastic sheet 1903 returns to its original state, and the second elastic sheet 1903 will drive the second baffle 1902 to rotate and close. Then, the telescopic rod of the first electric push rod 16 is controlled to shorten. When the telescopic rod of the first electric push rod 16 is separated from the first baffle 12 in the designated through hole 11, the first elastic sheet 13 returns to its original state, and the first elastic sheet 13 drives the first baffle 12 to reverse and close. Then, the pusher rack 2005 is driven to move to the left by the second cylinder 2004, so that the pusher rack 2005 drives the new cloth bag 3 at the bottom to the left, until the new cloth bag 3 at the bottom is at the top center of the first baffle 12. At the same time, when the pusher rack 2005 moves to the left, the pusher rack 2005 will support the remaining new cloth bag 3 in the storage barrel 2001. After the new cloth bag 3 at the bottom is at the top center of the first baffle 12, the pusher rack 2005 is driven to move to the right and reset by the second cylinder 2004. When the pusher rack 2005 is separated from the remaining new cloth bag 3 in the storage barrel 2001, the remaining new cloth bag 3 in the storage barrel 2001 falls downward, causing the next new cloth bag 3 at the bottom to fall to the top of the support plate 2003, and the next The new cloth bag 3 at the bottom is in the semi-ring structure of the pushing rack 2005, and then the brushless motor 1803 on the upper side drives the rubber sleeve 1804 to reverse, so that the rubber sleeve 1804 on the upper side drives the cage 4 to be transported downward by friction. When the bottom of the cage 4 is lower than the bottom of the rubber sleeve 1804 on the lower side, the fourth electric push rod 1801 on the lower side drives the connecting frame 1802, the brushless motor 1803 and the rubber sleeve 1804 to move to the side close to the cage 4 until the rubber sleeve 1804 on the lower side clamps the cage 4. At the same time, the brushless motor 1803 on the lower side drives the rubber sleeve 1804 to reverse, so that the rubber sleeve 1804 on the lower side also drives the cage 4 to be transported downward by friction. When the cage 4 and the top of the baffle 12 are When the new cloth bag 3 contacts, the cage 4 will extend into the new cloth bag 3. When the cage 4 contacts the bottom of the new cloth bag 3, the cage 4 will squeeze the first baffle 12 through the new cloth bag 3 to rotate and open, and the first elastic piece 13 will be deformed. Under the influence of the elastic force of the first elastic piece 13, the first elastic piece 13 will apply pressure to the first baffle 12, so that the first baffle 12 presses the new cloth bag 3 against the surface of the cage 4 to prevent the new cloth bag 3 from separating from the cage 4 after the first baffle 12 rotates open. Then, as the cage 4 continues to move downward, the cage 4 will drive the new cloth bag 3 to move downward together, so that the cage 4 brings the new cloth bag 3 onto the partition 2, thereby making the cage 4 bring the new cloth bag 3 into the designated bellows 8. When the cage 4 drops to separate from the rubber sleeve 1804 on the upper side,The fourth electric push rod 1801 on the upper side drives the connecting frame 1802, the brushless motor 1803 and the rubber sleeve 1804 to move and reset, and the brushless motor 1803 on the upper side drives the rubber sleeve 1804 to stop rotating. When the top of the cage 4 drops to the same height as the electric clamp 1703, the brushless motor 1803 on the lower side drives the rubber sleeve 1804 to stop reversing, so that the cage 4 stops moving downward, and then the third electric push rod 1702 drives the electric clamp 1703 to move closer to the cage 4. The electric clamp 1703 moves to one side until it contacts the cage 4, and then controls the electric clamp 1703 to clamp the cage 4, and then drives the connecting frame 1802, the brushless motor 1803 and the rubber sleeve 1804 to move and reset through the fourth electric push rod 1801 on the lower side, and then drives the third electric push rod 1702 and the electric clamp 1703 to move downward again through the second electric push rod 1701, so that the electric clamp 1703 clamps the cage 4 and moves downward until the electric clamp 1703 contacts the top surface of the partition 2, thereby The cage 4 is returned to its original position, and the cage 4 drives the new cloth bag 3 to return to the specified position, and at the same time, the telescopic rod of the first electric push rod 16 is controlled to extend. When the telescopic rod of the first electric push rod 16 contacts the first baffle 12, the telescopic rod of the first electric push rod 16 squeezes the first baffle 12 to continue to rotate and open, and the first elastic sheet 13 is deformed until the telescopic rod of the first electric push rod 16 squeezes the first baffle 12 to completely rotate and open, and then the electric clamp 1703 is controlled to release the cage 4, and then the third electric push rod 1 702 drives the electric clamp 1703 to move and reset, and then the third electric push rod 1702 and the electric clamp 1703 are driven to move upward and reset through the second electric push rod 1701 again, and then the telescopic rod of the first electric push rod 16 is controlled to shorten. When the telescopic rod of the first electric push rod 16 is separated from the first baffle 12, the first spring piece 13 returns to its original state, and the first spring piece 13 drives the first baffle 12 to reverse and close. In this way, the replacement operation of the new cloth bag 3 can be completed, thereby realizing automatic replacement of the old cloth bag 3;

[0044] Then, the first servo motor 1001 drives the first screw rod 1002 to reverse and reset, so that the first screw rod 1002 drives the iron plate 7 and the designated electromagnet 9 to move upward and reset, thereby restoring the designated bellows 8 to its original state, and then the designated bellows 8 releases the isolation of the new cloth bag 3, so that the new cloth bag 3 can start to filter the exhaust gas, and then the designated electromagnet 9 is powered off to release the designated electromagnet 9 from the top of the iron plate 7, and finally the waste cloth bag 3 in the storage frame 1901 is taken out for processing. In this way, the cloth bag 3 in the outer shell 1 can be automatically replaced without stopping the machine.

[0045] See also Fig.14As shown, it also includes a limiting mechanism, which includes a third cylinder 21 and a limiting ring 22; the third cylinder 21 is symmetrically arranged on the front and back sides of the inner side of the connecting frame 15; the limiting ring 22 is connected between the telescopic rods of the two third cylinders 21, and the limiting ring 22 is used to limit the cage frame 4 after rising.

[0046] By setting a limit mechanism, when the cage 4 rises to a height exceeding the limit ring 22, the limit ring 22 can be driven to move upward by the third cylinder 21 so that the limit ring 22 is at two-thirds of the height after the cage 4 stops rising. When the cage 4 slightly tilts after rising, the limit ring 22 can be used to limit and support the cage 4 to prevent the cage 4 from seriously tilting. Afterwards, when the cage 4 descends, the limit ring 22 can be driven to move downward and reset by the third cylinder 21.

[0048] By setting up a cleaning mechanism, when it is necessary to clean the dust adhered to the cloth bag 3 in the outer shell 1, the third screw 24 can be driven by the second reduction motor 23 to perform intermittent forward and reverse rotation, so that the third screw 24 drives the movable block 25 and the air outlet pipe 26 to perform intermittent reciprocating movement, so that the air outlet pipe 26 can stay directly above the cloth bag 3 for a period of time. During this period of stay, the compressed air is input into the air outlet pipe 26 through the air supply pipe 28 by the air tank 27, so that the air outlet pipe 26 can blow the compressed gas into the cloth bag 3 in the outer shell 1 to blow off the dust adhered to the surface of the cloth bag 3, thereby cleaning the dust adhered to the surface of the cloth bag 3; when it is necessary to replace the designated cloth bag 3, the air outlet pipe 26 needs to be moved to the top of the designated cloth bag 3 to prevent the air outlet pipe 26 from affecting the replacement of the designated cloth bag 3.
