Description

Technical Field

[0001] The invention relates to the technical field of industrial dust collectors, and 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 filter device that is suitable for capturing fine, dry, non-fibrous dust. The filter bag is made of textile filter cloth or non-textile felt, and uses the filtering effect of fiber fabric to filter the dust-containing gas. When the dust-containing gas enters the bag filter, the large particles and heavy dust settle down and fall into the ash hopper due to the effect of gravity. When the gas containing finer dust passes through the filter bag, the dust is retained, so that the gas is purified.

[0003] Currently, industrial filter bag 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. In addition, each filter bag frame and filter bag in the filter bag dust collector mostly need to be locked and installed on the filter bag mounting plate through multiple corresponding fixing bolts.

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

At the same time, the air flow speed slows down. Due to inertia, the coarse dust particles in the gas flow directly into the ash hopper. After passing through the ash hopper, the dust-containing gas enters the filter bag filtration area of ​​the middle box body. The gas passes through the filter bag, and the dust is retained on the outer surface of the filter bag. After the purified gas enters the upper box body through the filter bag port, it is discharged from the air outlet. As the filtration time increases, the dust layer on the filter bag continues to accumulate and the resistance continues to increase. When the resistance rises to the set value, the electromagnetic pulse valve opens, and the compressed air rapidly expands in the upper box body in a very short time and rushes into the filter bag, causing the filter bag to expand, deform and vibrate. Under the action of the reverse airflow, the dust attached to the outer surface of the filter bag is peeled off and falls into the ash hopper to achieve the dust removal effect. Since the dust collector body 1 belongs to the prior art in this field, it only includes and is not unique, so it will not be described in detail.

[0020] An industrial filter bag dust collector also includes a swinging member, a lifting member, a mounting member and a clamping member.

[0022] In this embodiment, Figure 1 and Figure 2 As shown, the lifting member includes a support frame 51, a double-axis motor 52, a rotating rod 53, a fixed block 54, a first bevel gear 55, a support shaft 57 and a second bevel gear 56. The support frame 51 is fixed on the dust collector body 1, and the double-axis motor 52 is fixed on the support frame 51. The double-axis motor 52 has two output shafts, and the output shafts at both ends are fixedly connected to the rotating rod 53, so that the pulleys 6 on both sides are synchronously driven to be lifted. The rotating rod 53 is fixed to the output end of the double-axis motor 52, and the fixed block 54 is fixed to the dust collector body 1. The rotating rod 53 can be ensured to rotate smoothly and stably through the fixed block 54.

The design of the support shaft 57 can ensure that the second bevel gear 56 can rotate smoothly and stably. The second bevel gear 56 meshes with the first bevel gear 55 .

[0023] In this embodiment, Figure 3 , Figure 4 and Figure 5 As shown, the mounting member includes a screw groove 1101 and a thread bar 1201. The screw groove 1101 is provided on the sleeve 11, and the thread bar 1201 is installed in the filter bag frame 12. The screw groove 1101 is threadedly connected with the thread bar 1201. The screw groove 1101 extends along the length direction of the sleeve 11, and is used to accommodate and fix the thread bar 1201.

[0024] In this embodiment, Figure 4 and Figure 5As shown, the clamping member includes a connecting block 1301, a through hole 1302, a plug rod 1303 and a spring 1304. The connecting block 1301 is fixed on opposite sides of the filter bag frame 12. The through hole 1302 is provided on the connecting block 1301. The plug rod 1303 is slidably connected to the connecting block 1301. The spring 1304 is sleeved on the plug rod 1303. The plug rod 1303 is arranged in a T-shape. The plug rod 1303 is provided with an upward protrusion. The two ends of the spring 1304 are respectively fixedly connected to the upward protruding bottom surface of the plug rod 1303 and the top surface of the connecting block 1301. The shape and size of the through hole 1302 should match the plug rod 1303 to ensure that the plug rod 1303 can slide and fix smoothly. The T-shaped portion of the plug rod 1303 has an upward protrusion portion for connecting with the spring 1304 and preventing the plug rod 1303 from completely sliding out of the connecting block 1301. The other end of the plug rod 1303 (i.e., the non-T-shaped portion) is used to be inserted into the insertion hole 1306 on the rotating shaft 1305 to achieve the fixation of the filter bag 13 and the filter bag frame 12. The spring 1304 is sleeved on the plug rod 1303 to provide resistance to the sliding of the plug rod 1303 and a fixing force. The two ends of the spring 1304 are respectively fixedly connected to the upwardly protruding bottom surface of the plug rod 1303 and the top surface of the connecting block 1301 to ensure that the plug rod 1303 can maintain a stable position and state when subjected to external forces.

[0025] In this embodiment, Figure 4 and Figure 5 As shown, the clamping member also 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 in 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 on 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 being deformed or loosened when subjected to force.

[0026] 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.

[0027] 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 allows the insertion rod 1303 and the socket 1306 to be 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.

[0028] In this embodiment, Figure 5As shown, the filter bag 13 is bonded to the felt surface 14, and the felt surface 14 is provided with bondable wool 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.

[0029] 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 according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it is not repeated here.

[0030] 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 driving motor 32 is started, the driving 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 realizing the dust collection operation of the target area.

[0031] 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 rotate the filter bag frame 12 to move the thread bar 1201 along the thread track of the screw groove 1101 and gradually tighten it. 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.

[0032] When installing the filter bag, first pull the insertion rod 1303 upward and stretch the spring 1304, so that the insertion rod 1303 is disengaged 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 is disengaged from the bottom of the filter bag frame 12, then the bottom of the filter bag 13 is sleeved under the filter bag frame 12, and its top is in contact with the felt surface 14 and bonded, and then flip the block 1307. The block 1307 is driven by the force to drive the rotating shaft 1305 placed in the through hole 1302 to rotate, and when it rotates to the same vertical plane as the clamping plate 1309 on the top of the filter bag frame 12, the pull rod is released, and the spring 1304 releases the tension. The elastic property thereof drives the pressure to be released and reset, thereby driving the insertion rod 1303 to reset to the limit position in the insertion hole 1306 embedded in the rotating shaft 1305, and then the threaded rod 1308 is rotated. The threaded rod 1308 is forced to drive the clamping plate 1309 to slide upward 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 the rapid installation and disassembly of the filter bag 13, thereby improving the installation efficiency of the filter bag 13 and improving its use effect.

[0033] The above shows and describes the basic principles, main features and advantages of the present invention. Technical personnel in this industry should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not used to limit the present invention.
