Description

Technical Field

[0001] The present invention relates to the technical field of industrial dust collectors, in particular to an industrial filter bag dust collector. Background Art

[0002] The bag filter is one of the most commonly used dust collectors in industrial dust removal. It is a dry dust filtration device suitable for capturing fine, dry, non-fibrous dust. The filter bag is made of textile filter cloth or non-woven felt, and uses the filtering effect of the fiber fabric to filter the dust-laden gas. When the dust-laden gas enters the bag filter, the large particles with high specific gravity settle due to gravity and fall into the ash hopper. The gas containing finer dust is retained when passing through the filter bag, and the gas is purified.

[0003] Currently, industrial bag filter dust collectors on the market are often fixed, that is, they cannot be moved after installation, which limits the scope of use and reduces the dust removal effect. Moreover, each bag filter frame and filter bag in the bag filter dust collector mostly need to be locked and installed on the bag filter mounting plate through multiple corresponding fixing bolts. Due to the large number of filter bags, the on-site installation workload of the filter bags is large, resulting in relatively low processing efficiency. Summary of the Invention

The first bevel gear on the rotating rod rotates accordingly, and meshes with the second bevel gear through the tooth surface to transmit the rotational motion. Since the tooth surfaces of the first bevel gear and the second bevel gear are inclined, their rotational motion will be converted into a lifting motion along the direction of the support shaft. The screw matched with the thread of the second bevel gear then drives the pulley to descend and fit into the ground. The dust collector can be moved by pushing the dust collector to move through the pulley, thereby increasing the scope of use and improving the dust removal range.

The card block is flipped to drive the rotating shaft to rotate. When the filter bag is rotated, the pull rod is released below the filter bag, and the insertion rod is forced to reset and limit the insertion hole embedded in the rotating shaft. The rotating threaded rod drives the clamping plate to slide up and fit tightly with the filter bag, thereby further compressing and fixing the filter bag and the filter bag frame, so that the filter bag can be quickly loaded and unloaded, thereby improving the loading and unloading efficiency of the filter bag.

[0030] In this embodiment, Figure 3 、 Figure 4 and Figure 5 As shown, the mounting member includes a screw groove 1101 and a threaded bar 1201. The screw groove 1101 is provided on the sleeve 11, and the threaded bar 1201 is installed in the filter bag frame 12. The screw groove 1101 is threadedly connected to the threaded bar 1201. The screw groove 1101 extends along the length of the sleeve 11 and is used to accommodate and fix the threaded bar 1201.

[0031] In this embodiment, Figure 4 and Figure 5As shown, the connector includes a connecting block 1301, a through hole 1302, a rod 1303, and a spring 1304. The connecting block 1301 is fixed to opposite sides of the filter bag frame 12. The through hole 1302 is provided on the connecting block 1301. The rod 1303 is slidably connected to the connecting block 1301. The spring 1304 is sleeved on the rod 1303. The rod 1303 is arranged in a T-shape and has an upward protrusion. The two ends of the spring 1304 are fixedly connected to the upwardly protruding bottom surface of the rod 1303 and the top surface of the connecting block 1301, respectively. The shape and size of the through hole 1302 should match the rod 1303 to ensure smooth sliding and fixation. The T-shaped portion of the rod 1303 has an upward protrusion that connects to the spring 1304 and prevents the rod 1303 from completely sliding out of the connecting block 1301. The other end of rod 1303 (i.e., the non-T-shaped portion) is inserted into socket 1306 on shaft 1305, securing filter bag 13 to filter bag frame 12. A spring 1304 is sleeved onto rod 1303, providing resistance to sliding and a securing force. The ends of spring 1304 are fixedly connected to the upwardly protruding bottom surface of rod 1303 and the top surface of connecting block 1301, respectively, to ensure that rod 1303 maintains a stable position and state when subjected to external forces.

[0032] In this embodiment, Figure 4 and Figure 5 As shown, the clamping member further includes a rotating shaft 1305, a socket 1306, a clamping block 1307, a threaded rod 1308, and a pressing plate 1309. The rotating shaft 1305 is rotatably connected to the through hole 1302, the socket 1306 is provided on the rotating shaft 1305, the clamping block 1307 is fixedly sleeved on the rotating shaft 1305, the threaded rod 1308 is rotatably connected to the clamping block 1307, and the pressing plate 1309 is fixed to the threaded rod 1308. It can be in close contact with the contact surface and provide sufficient pressing force to prevent the filter bag frame 12 from deforming or loosening when subjected to force.

[0033] It should be noted that when replacing the filter bag frame 12 and the filter bag 13, the outer door on the dust collector can be opened for replacement. Since the installation of the outer door of the dust collector belongs to the existing technology in this field, it will not be described in detail.

[0034] In this embodiment, Figure 4 and Figure 5 As shown, the insertion rod 1303 and the socket 1306 are in the same vertical plane. This design makes the insertion rod 1303 and the socket 1306 aligned in space. This alignment relationship ensures that the insertion rod 1303 can be smoothly and accurately inserted into the socket 1306, avoiding misalignment and deviation of the insertion rod 1303 and the socket 1306 during the installation process.

[0035] In this embodiment, Figure 5As shown, the filter bag 13 is bonded to the felt surface 14. The felt surface 14 is provided with bondable balls, which form a bonding effect when in contact with the filter bag 13, similar to the Velcro bonding form, so that the filter bag 13 can be preliminarily installed.

[0036] It should be noted that the specific models and specifications of the drive motor 32 and the dual-axis motor 52 need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it is not repeated here.

[0037] The industrial filter bag dust collector of the present invention is in operation. Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, when the drive motor 32 is started, the drive motor 32 drives the transmission rod 33 to rotate, and the rotational motion of the transmission rod 33 is converted into the swinging motion of the rotating handle 36 through the crank 34 and the connecting rod 35. The swinging motion of the rotating handle 36 drives the dust hood 3 to reciprocate, thereby achieving the dust collection operation of the target area.

[0038] When installing the filter bag frame 12, first insert the filter bag frame 12 into the sleeve 11, ensure that the thread bar 1201 is aligned with the screw groove 1101, then, by rotating the filter bag frame 12, the thread bar 1201 moves along the thread track of the screw groove 1101 and is gradually tightened. When the thread bar 1201 is completely screwed into the screw groove 1101, a firm threaded connection is formed between the filter bag frame 12 and the sleeve 11, thereby achieving fixed installation of the filter bag frame 12.

[0039] When installing the filter bag, first pull the insertion rod 1303 to slide up and stretch the spring 1304, so that the insertion rod 1303 disengages from the socket 1306 on the rotating shaft 1305, flip the block 1307 so that it is on the same horizontal plane as the filter bag frame 12 and disengages from the bottom of the filter bag frame 12, then put the bottom of the filter bag 13 under the filter bag frame 12, and its top is in contact with the felt surface 14 and bonded, then flip the block 1307, and the block 1307 is driven by the force to drive the rotating shaft 1305 to rotate in the through hole 1302, and when it rotates to the same vertical plane as the clamping plate 1309 at its top and the bottom surface of the filter bag frame 12, release the pull rod, and the spring 1304 releases the tension. Through its own elastic properties, it drives the pressure release to reset, and then drives the insertion rod 1303 to reset to the limit position in the socket 1306 embedded in the rotating shaft 1305, and then rotates the threaded rod 1308. The threaded rod 1308 is forced to drive the clamping plate 1309 to slide up until the clamping plate 1309 is tightly fitted with the bottom surface of the filter bag frame 12, so that the filter bag 13 and the filter bag frame 12 are further compressed and fixed. When the filter bag needs to be removed, only the above steps need to be reversed to remove the filter bag 13 from the filter bag frame 12, thereby realizing rapid installation and disassembly of the filter bag 13, improving the installation efficiency of the filter bag 13, and improving its use effect.

It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention.
