In practice, the cartridge 103 is typically up to 1.5 meters in length, and therefore has a large overall weight, requiring good support at the left end. On the other hand, as described above, in order to prevent industrial exhaust gas from being directly sucked away from between the filter cartridge 103 and the driven ring rail 107, a sealing structure 110 is provided between the inner wall of the filter cartridge 103 and the driven ring rail 107, and for example, the sealing structure 110 may be provided as a seal ring or a graphite packing or the like, see fig. 5C.
As can be seen in conjunction with fig. 3, the portion of the filter cartridge 103 above the height of contact with the brush roll cleaning assembly 200 can be considered as an industrial waste gas suction zone, i.e., industrial waste gas is sucked into the filter cartridge 103 from the upper half of the filter cartridge 103, while the lower half of the filter cartridge 103, together with the brush roll cleaning assembly 200 and the extrusion assembly 300, forms a dust treatment zone or dust collection cavity, which is always in a negative pressure zone. For good handling, a sealed connection between the driven ring rail 107 and the filter cartridge 103 is necessary, which would otherwise lead to an inefficient removal of dust flock.
In one embodiment, referring to fig. 5D and 5E, one end of the steam purge assembly 400 is coupled to the cartridge drive plate 101, i.e., movably coupled to the cartridge drive plate 101, such that rotation of the drive shaft 106 rotates the cartridge 103, but the steam purge assembly 400 is stationary. The other end of steam purge assembly 400 is movably connected thereto through central aperture 108 of slave ring rail 107.
The filter cartridge 103 is further provided with annular inner filter cartridge supports 105 distributed along the longitudinal direction of the filter cartridge 103 to support the filter cartridge 103 from inside the filter cartridge 103. As mentioned above, the filter cartridge 103 is generally longer and, because it is made of steel plate, it is heavier and requires better support.
Referring to fig. 6, a structural view after cutting along line B-B of fig. 4 shows a specific structure of the steam cleaning assembly 400.
Since industrial waste gas contains a large amount of oil-containing particulate matter, it is accumulated on the outer wall surface of the cartridge filter assembly 100, resulting in difficulty in effective cleaning.
In the illustrated example, the interior of the cartridge filter assembly 100 is provided with a steam purge assembly 400 to effectively remove soot particulates by injecting steam.
In practice, the soot particulate contaminants on the filter screen 104 or filter cartridge 103 are cleaned by the high temperature and pressure.
The steam cleaning assembly 400 includes a steam nozzle 402 and a plurality of steam holes disposed on the steam nozzle 402. The steam cleaning assembly 400 is stationary within the cartridge filter assembly 100, i.e., it does not rotate with the rotation of the cartridge filter assembly 100. In fact, the steam holes in the steam purge assembly 400 always blow steam toward the underside of the filter cartridge 103.
In one example, the steam cleaning assembly 400 further includes an internal wire connection 403, a steam inlet connection pipe 404, a steam valve 405, a steam nozzle shaft seat 406, a steam nozzle shaft plug 407, and a bearing 408.
The steam nozzle 402 is provided in a downwardly bent shape, and specifically, the steam nozzle 402 includes a flat first tube segment 4021, a downwardly extending second tube segment 4022 connected to the first tube segment 4021, a flat third tube segment 4023 connected to the second tube segment 4022, an upwardly extending fourth tube segment 4024 connected to the third tube segment 4023, and a flat fifth tube segment 4025 connected to the fourth tube segment 4024 and extending outwardly.
Preferably, the second tube segment 4022 and the fourth tube segment 4024 are angled between 60 and 170 degrees relative to the third tube segment 4023. For simplicity and efficiency, the included angle between them is approximately 90 degrees, which may allow the third tube segment 4023 to extend sufficiently downward closer to the cartridge 103 for steam blowing under the same conditions. In fact, due to the fact that the steel tube is at a bend, the second tube segment 4022 and the fourth tube segment 4024 are connected to the third tube segment 4023 by an arc or a slow bend. Alternatively, the extensions of second tube segment 4022 and fourth tube segment 4024 are perpendicular to third tube segment 4023.
The first tube segment 4021 is connected at the left end by a threaded connection to an internal thread connector 403, the internal thread connector 403 being fixedly connected to the cartridge filter assembly 100 (specifically, from the central bore 108 of the moving ring rail 107) and by a threaded connection to an intake connection tube 404, the intake connection tube 404 being in a conduit connection with a steam valve 405, the steam valve 405 controlling the flow of steam into the intake connection tube 404. The right end of the steam nozzle 402 is movably connected to a bearing 408 provided on the cartridge drive plate 101, the bearing 408 being connected to a steam nozzle shaft mount 406 and a steam nozzle plug 407 being provided on the end.
The steam nozzle 402 is provided with a plurality of air injection holes arranged at intervals, and the size and shape of the air injection holes and the interval between two adjacent air injection holes can be selected according to actual needs.
Reinforcing the support of the steam nozzle 402, a steam brace 401 is also provided at a position where the steam nozzle 402 is bent downward. Specifically, a steam strut 401 is disposed between the second tube segment 4022 and the fourth tube segment 4024. The steam struts 401 are disposed at their locations proximate to either the first tube segment 4021 or the fifth tube segment 4025.
The cartridge filter assembly 100 is allowed to rotate by providing an internal wire connection 403 at the left end and a bearing 408 and steam nozzle shaft seat 406 at the right end, etc., while the steam cleaning assembly 400 remains stationary, always blowing steam toward the side where the brush roll ash assembly 200 is located. This cleans the entire cartridge 103 of soot particulates.
Referring to fig. 3 and 7, the brush roll cleaning assembly 200 is disposed below the cartridge filter assembly 100 and in at least a partial position the brush roll cleaning assembly 200 is in contact with the cartridge filter assembly 100 to facilitate the removal of dust flock therefrom.
The brush roll ash removal assembly 200 comprises a brush roll 201, a brush roll connecting shaft 202, a belt seat bearing 203, an adjusting block 204, a cleaning brush 205, a first baffle 206, a second baffle 209, a baffle adjusting plate 207, a bottom plate 208 and the like.
The brush roller 201 is rotatably provided on the base plate 208. Specifically, the brush roller 201 is rotatably provided on a brush roller connecting shaft 202. The brush roller connecting shaft 202 is disposed on the belt seat bearing 203, for example, the brush roller connecting shaft 202 is disposed in the belt seat bearing 203 and is movably connected to both ends thereof so as to be rotatable.
In order to adjust the height of the brush roller 201 to adjust the gap between the worn brush roller 201 and the filter cartridge 103, a seated bearing 203 may be provided on the adjustment block 204 together with the brush roller connecting shaft 202.
On the other side of the bottom plate 208, a roller bearing 203 is provided, and a brush roller connecting shaft 202 is provided on the roller bearing 203, and a brush roller 201 is provided on the brush roller connecting shaft 202. The brushroll connecting shaft 202 may connect the brushroll 201 and allow the brushroll 201 to be driven in rotation.
The seat bearing 203 is connected to the base plate 208 by an adjustment block 204 in a height-adjustable manner, i.e., the gap between the brushroll 201 and the filter cartridge 103 can be adjusted as the brushroll 201 wears.
To clean the dust flock on the brush roller 201, a cleaning brush 205 may be provided on the base plate 208 at a position close to the brush roller 201 to facilitate cleaning of the dust flock.
Correspondingly, a first baffle 206 is also provided on the bottom plate 208 or the adjusting block 204 in the outward direction of the brush roller 201 to allow the dust flock at the lower right end of the filter cartridge 103 to fall into the pressing assembly 300 to the maximum extent.
The first damper 206 is disposed on the adjustment block 204 such that the height of the first damper 206 is adjusted accordingly while the height of the adjustment block 204 is adjusted.
A baffle adjustment plate 207 and a second baffle 209 fixedly coupled to the baffle adjustment plate 207 are provided at one end of the bottom plate 208, and the second baffle 209 is spaced apart from the lower portion of the filter cartridge 103 by a small gap, thereby allowing the filter cartridge 103 to rotate and to maximally block dust flock on the filter cartridge 103 and drop into the pressing assembly 300 (e.g., screw press) provided below. In practice, the filter cartridge 103 rotates counterclockwise, and the brush roller 201 contacts the filter cartridge 103 and rotates clockwise, brushing the dust flock down.
The first baffle 206 and the second baffle 209 are provided in the shape of outwardly turned arcuate plates so as to facilitate collection of dust falling thereon and which match the shape of the bottom of the filter cartridge 103 to help form a closed dust collection cavity.
Referring to fig. 8, the brush roll ash removal assembly 200 generally assumes an upwardly open cavity shape with the curvature of the first baffles 206 on both sides generally matching the filter cartridge 103.
Through the open cavity, the dust flock brushed off the filter cartridge 103 falls into the extrusion assembly 300 and is extruded.
In one example, the extrusion assembly 300 may be a screw extruder.
As can be seen in fig. 8, the middle of the bottom plate 208 is hollow, such that the first baffle 206, the brush roller 201, the bottom plate 208, the second baffle 209 and the baffle adjustment plate 207 form a closed dust collecting cavity with the pressing assembly 300 arranged therebelow. That is, the dust collection chamber as a whole can be considered a large funnel.
Referring to fig. 9, a drive assembly 600 in this example is shown. As described above, the industrial waste gas dust removing device includes the cartridge filter assembly 100 connected to the industrial waste gas outlet, the brush roll ash removing assembly 200 disposed below the cartridge filter assembly, and the extrusion assembly 300 disposed below the brush roll ash removing assembly 200 and in communication therewith, the extrusion assembly 300 being located at a side lower portion of the industrial waste gas dust removing device.

The driving force of the driving mechanism such as motor driving can be controlled by the controller 601 and the rotation speed of the driving shaft 106 can be controlled by the reduction motor 607. The gear motor 607 is mounted on the motor mounting seat 606, and the motor shaft of the gear motor 607 is connected with the driving sprocket 602 and the driven sprocket 604 through the chain 603.
The outer side of the chain 603 adjusts the tension of the chain 603 by tensioning the sprocket 605. The drive sprocket 602 is directly or indirectly coupled to the drive shaft 106 to drive rotation thereof.
In one example, a drive sprocket 602 is coupled to and drives rotation of the drive shaft 106 of the cartridge filter assembly 100. The driven sprocket 604 is coupled to the screw of the pressing assembly 300 to rotate it.
