Description

Technical Field

[0001] The invention relates to the technical field of dust removal filter bags, and in particular to a vertical, easy-to-maintain, high-strength dust removal filter bag. Background Art

[0002] Dust filter bags are highly effective filter media with excellent ventilation, high dust collection efficiency, and resistance to acids, alkalis, and heat. Multi-sided brushing is used during the weaving process to increase fabric thickness and elasticity, resulting in excellent dust removal performance, with a dust removal rate of up to 99.999%. Dust filter bags are made from polyester staple or long fibers, and their service life is generally 4-6 times that of fiberglass fabrics. They offer excellent air permeability, a high dust collection rate, and are easy to clean, with a dust removal efficiency of up to 98.99%.

[0003] Most dust filter bags are made into upright ones because they are easier to maintain. Existing dust filter bags are installed inside the dust collector. Industrial production and processing will produce dust-laden gas. The dust-laden gas filtration requires the use of a dust collector. The dust-laden gas enters the dust collector from the air inlet and passes through the guide plate of the ash hopper. Some large dust particles in the gas are separated by the inertial force and fall directly into the ash hopper. The dust-laden gas enters the filter area of the filter bag of the box. Most of the dust is captured on the outer surface of the filter bag, and the clean gas enters the filter bag through the filter material. The purified gas enters the upper box through the filter bag port and is discharged from the air outlet. However, the dust filter bag During the filtering process, a large amount of dust will accumulate on the surface of the dust filter bag. However, in order to avoid frequent handling of the dust filter bag, some dust collectors are equipped with an explosion device. However, when the explosion device processes the dust on the surface of the dust filter bag, the air is backblown, so that the air is blown out from the inside of the dust filter bag to the outside, thereby processing the dust on the surface of the dust filter bag. However, during the filtering and explosion process, the dust filter bag is prone to separation from the internal support frame, resulting in partial damage to the dust filter bag. At the same time, the stability of the internal support frame deteriorates, resulting in a decrease in the filtration efficiency of the dust filter bag. Summary of the Invention

[0016] Beneficial effects of the present invention:

[0017] 1. The present invention provides a dust filter bag, a support ring, a support column, a reinforced support structure, a limiting structure, a limiting guide structure and a stable positioning structure for coordinated use. The dust filter bag can be supported by the support ring and the support column, the support column can be supported by the reinforced support structure, the limiting structure can support the reinforced support structure, the limiting guide structure can guide the reinforced support structure, and the stable positioning structure can connect and fix the dust filter bag to the support column and the reinforced support structure, thereby solving the problems of unstable internal support of the existing dust filter bag and easy separation of the dust filter bag from the support frame.

[0018] 2. The present invention is provided with a reinforced support structure, which can rotate the transmission column, and the transmission column drives the transmission nut to rotate, and the transmission nut drives the transmission rod to transmit through the first rotating shaft. Since the rotating disk is movably connected to the surface of the transmission column, the rotating disk is fixedly connected to the guide rail, and the transmission rod drives the first fixed block to move through the second rotating shaft, the first fixed block will drive the sliding sleeve to slide on the guide rail, so that the sliding sleeve supports the support column, thereby increasing the supporting strength of the dust filter bag and the support column.

[0019] 3. The present invention can provide limited support for the transmission column by setting a limiting structure, thereby reducing the shaking of the transmission column. When the transmission column rotates, the transmission column will drive the limiting base to rotate, and the limiting base will rotate inside the first bearing. Since the first bearing is fixedly connected to the connecting plate, the connecting plate is connected to the retaining ring, and the retaining ring is clamped on the surface of the support column, thereby achieving support and limiting of the bottom of the reinforced support structure, and facilitating the rotation of the reinforced support structure.

[0020] 4. The present invention sets a limiting guide structure, so that when the sliding sleeve moves, the sliding sleeve will drive the fixed plate to move. At the same time, the user holds the guide rod to facilitate the rotation of the transmission column. The fixed plate will slide and move on the surface of the guide rod.

[0021] 5. The present invention sets a stable positioning structure, which can be fixed on the surface of the dust filter bag through a pressure plate. The fixing column on the surface of the pressure plate passes through the dust filter bag and then passes into the interior of the second fixed block, so that the pressure plate can perform preliminary limiting fixation on the dust filter bag, avoid the dust filter bag from detaching from the support column, and increase the stability of the connection between the dust filter bag and the support column.

[0022] 6. The present invention can fix the transmission handle through the top of the transmission column by setting a transmission handle, a power rod and a second bearing, which can facilitate the rotation of the transmission column. The power rod can rotate the transmission handle and increase the torque of the transmission handle. The transmission column is connected to the rotating disk through the second bearing, which can facilitate the rotation of the rotating disk on the surface of the transmission column and at the same time limit the rotating disk.

[0023] 7. The present invention facilitates the installation and removal of the connecting plate and the clamping ring by providing screws, thereby facilitating replacement of the clamping ring after damage and facilitating disassembly between structures.

[0024] 8. The present invention provides a locking block, a return spring and a pressure strip. The locking block can be provided inside the annular groove to assist in limiting and fixing the fixed column. The return spring can make the locking block better contact with the fixed column, thereby increasing the flexibility of structural installation and disassembly. By providing a pressure strip between the pressure plate and the dust filter bag, the force area of the pressure plate squeezing the dust filter bag can be increased, so that the dust filter bag can be better connected and fixed to the support column, avoiding the separation of the dust filter bag from the support column, thereby increasing the dust removal effect.

By setting the limiting structure 5, the transmission column 41 can be limited and supported to reduce the shaking of the transmission column 41. When the transmission column 41 rotates, the transmission column 41 will drive the limiting base 51 to rotate, and the limiting base 51 will rotate inside the first bearing 52. Since the first bearing 52 is fixedly connected to the connecting plate 53, and the connecting plate 53 is connected to the snap ring 54, the snap ring 54 is stuck on the surface of the support column 3, thereby realizing the support and limitation of the bottom of the strengthening support structure 4, and facilitating the rotation of the strengthening support structure 4.

[0040] The limiting guide structure 6 includes a guide ring 61 and three sets of fixed plates 62. The guide ring 61 is located at the top of the surface of the transmission column 41.

The side of the guide rod 64 away from the limiting ring 63 is fixedly connected to the inner ring of the guide ring 61. The bottoms of the three sets of fixed plates 62 are fixedly connected to the top of the sliding sleeve 44. The tops of the two bottom sets of fixed plates 62 are fixedly connected to the bottoms of the two top sliding sleeves 44. The top fixed plate 62 is movably connected to the surface of the guide rod 64. By setting the limiting guide structure 6, when the sliding sleeve 44 moves, the sliding sleeve 44 will drive the fixed plate 62 to move. At the same time, the user holds the guide rod 64 to facilitate the rotation of the transmission column 41. The fixed plate 62 will slide and move on the surface of the guide rod 64. The limiting ring 63 plays a limiting role on the fixed plate 62, which can synchronize the three sets of sliding sleeves 44 to support and fix the support column 3.

[0041] When the locking cam 73 is unlocked, the locking cam 73 is unlocked, and the lock 73 is unlocked, so that the master can lock the lock 73. When the lock 73 is unlocked, the master can lock the lock 73 in the open position, and the lock 73 is unlocked, so that the master can lock the lock 73 in the open position.

[0042] The top of the transmission column 41 is fixedly connected with a transmission handle 8, and the four corners of the surface of the transmission handle 8 are fixedly connected with power-assisting rods 9. A second bearing 10 is provided inside the rotating disk 42, and the interior of the rotating disk 42 is movably connected to the surface of the transmission column 41 through the second bearing 10. By arranging the transmission handle 8, the power-assisting rod 9 and the second bearing 10, the transmission handle 8 can be fixed through the top of the transmission column 41, which can facilitate the rotation of the transmission column 41. The power-assisting rod 9 can rotate the transmission handle 8 and increase the torque of the transmission handle 8. The transmission column 41 is connected to the rotating disk 42 through the second bearing 10, which can facilitate the rotation of the rotating disk 42 on the surface of the transmission column 41 and at the same time limit the rotating disk 42.

[0043] Screws 11 are provided at the four corners of the top of the connecting plate 53. The threaded ends of the screws 11 pass through the connecting plate 53 and extend to the inside of the retaining ring 54. By providing the screws 11, the installation and disassembly of the connecting plate 53 and the retaining ring 54 can be facilitated, thereby facilitating the replacement of the retaining ring 54 after damage, and also facilitating disassembly between structures.

[0044] The interior of the annular groove 73 is provided with a locking block 12, and the side of the locking block 12 away from the fixing post 72 passes through the interior of the second fixing block 74. The top and bottom of the locking block 12 away from the fixing post 72 are fixedly connected to a return spring 13, and the side of the return spring 13 away from the locking block 12 is fixedly connected to the inner wall of the second fixing block 74. The surface of the support column 3 is provided with a pressure strip 14, and the side of the pressure strip 14 close to the dust filter bag 1 is used in conjunction with the surface of the dust filter bag 1.

A locking block 12, a return spring 13 and a pressure strip 14 are provided. The locking block 12 can be provided inside the annular groove 73 to assist in limiting and fixing the fixing column 72. The return spring 13 can enable the locking block 12 to better contact the fixing column 72, thereby increasing the flexibility of structural installation and disassembly. By providing a pressure strip 14 between the pressure plate 71 and the dust filter bag 1, the force area of the pressure plate 71 squeezing the dust filter bag 1 can be increased, so that the dust filter bag 1 can be better connected and fixed to the support column 3, avoiding the dust filter bag 1 from being separated from the support column 3, thereby increasing the dust removal effect.

[0045] Working principle: When the user needs to support the dust filter bag 1, first clamp the clamping ring 54 on the surface of the support column 3, then place the connecting plate 53 on the top of the clamping ring 54, and fix the connecting plate 53 on the top of the clamping ring 54 through the screw 11 to fix the connection so that the connecting plate 53 and the clamping ring 54 are connected together, and then the reinforcing support structure 4 and the limiting guide structure 6 are placed between the support column 3 until the bottom of the transmission column 41 is inserted into the interior of the limiting base 51, and the limiting base 51 supports the transmission column 41. At the same time, the hand is on the guide rod 64.

The transmission column 41 is connected to the transmission nut 46 through a thread. Since the rotating disk 42 is movably connected to the surface of the transmission column 41 through the second bearing 10, the rotating disk 42 is fixedly connected to the guide slide rail 43, and the transmission rod 47 drives the first fixed block 4 through the second rotating shaft 5 moves, the first fixed block 45 drives the sliding sleeve 44 to slide on the guide rail 43, so that the sliding sleeve 44 supports the support column 3, achieving the purpose of preliminarily strengthening the support column 3. When the sliding sleeve 44 moves, the sliding sleeve 44 drives the fixed plate 62 to move. The fixed plate 62 slides on the surface of the guide rod 64, and the limiting ring 63 limits the fixed plate 62. Then, the pressure strip 14 is pressed on the surface of the dust filter bag 1 and the support column 3, and is fixed on the surface of the pressure strip 14 by the pressure plate 71. The pressure plate 71 The rear fixing column 72 passes through the pressure strip 14 and the dust filter bag 1 and extends to the inside of the second fixing block 74. When the annular groove 73 is flush with the locking block 12, the return spring 13 rebounds and the locking block 12 is stuck in the annular groove 73 for limiting and fixing, so that the dust filter bag 1 can be better connected to the support column 3, avoiding the separation of the dust filter bag 1 and the support column 3 during explosion, and can also stabilize the positioning structure 7 and the sliding sleeve 44.
