Description

Technical Field

[0001] The invention relates to the technical field of feed processing dust removal, and in particular to a pulse bag dust collector, a dust removal method and a feed processing technology. Background Art

[0002] The pulse bag filter is a highly efficient bag dust removal equipment, which is widely used in dust collection and gas purification in industrial production. It filters the dusty gas through the filter bag and removes the dust on the filter bag by pulse spraying technology, so as to achieve the purpose of purifying the air. The pulse bag filter has the advantages of large air volume, good dust cleaning effect, high dust removal efficiency, reliable operation and convenient maintenance. The working principle of the pulse bag filter is that the dusty gas first passes through the ash hopper, where the larger dust particles fall directly into the ash hopper, while the finer dust enters the filter chamber with the air flow. In the filter chamber, the dust is intercepted by the filter bag, and the purified gas enters the upper box through the filter bag and is discharged through the exhaust pipe. As the filtering time increases, the dust layer on the filter bag will gradually thicken, resulting in an increase in the equipment resistance. When the resistance reaches the set value, the dust cleaning control device will start the pulse spraying system, spray the filter bag with compressed air, so that the filter bag expands and shakes off the dust, restoring the filtering capacity of the filter bag.

[0003] In order to ensure the efficient operation of the pulse bag dust collector, regular maintenance and inspection are required, including checking the integrity of the filter bags, the working status of the dust cleaning system, and the accuracy of the control system. Among them, optimizing operating parameters, such as filtration speed and dust cleaning cycle, is also an important measure to improve dust removal efficiency and reduce operating costs.

[0004] However, the existing bag dust collectors, especially the miniaturized bag dust collectors, have a short cleaning cycle due to the size limitation. As a result, during the feed processing, the dust quickly clogs the bags and filters, causing the feed processing to be suspended, making it difficult to meet the needs of continuous processing and saving cleaning costs.

[0017] A feed processing process, characterized by using the above-mentioned pulse bag dust collector.

[0018] Compared with the prior art, the present invention provides a pulse bag dust collector, a dust removal method and a feed processing technology, which have the following beneficial effects:

[0019] 1. In this pulse bag dust collector, when the dust-laden gas passes through the isolation baffle, part of the dust in the dust-laden gas can be intercepted by the isolation baffle and attached to the surface of the isolation baffle. Due to the flow of the dust-laden gas, when the dust-laden gas passes through each dust collector bag in the dust collector chamber, the dust in the dust-laden gas can be intercepted by the dust collector bag on the outer surface of the dust collector bag, and the gas in the dust-laden gas can pass through the dust collector bag and the exhaust baffle into the exhaust chamber, thereby completing the separation of the dust and gas in the dust-laden gas. Then, when needed, the flapping unit reciprocates and extends inside the bag frame under the drive of the cleaning drive unit, and when the flapping unit extends out from the inside of the bag frame, the dust collector bag sleeved on the outside of the bag frame is driven to vibrate under its own elasticity, and the dust on the outer surface of the dust collector bag is shaken off to the dust collecting chamber, thereby completing the cleaning process of each dust collector bag, and effectively restoring the dust removal effect of each dust collector bag, avoiding the interruption of the dust removal work and ensuring the continuous progress of the dust removal work.

[0020] 2. This type of pulse bag dust collector has a frame pressing protrusion that can abut the top of the frame movable rod during the downward rotation process, driving the frame movable rod and the frame driving rod to overcome the elastic force of the frame return spring and move downward. When the frame pressing protrusion rotates upward, the frame return spring returns, driving the frame movable rod and the frame driving rod to move upward and reset, and continuously drives the movable lower frame to reciprocate up and down, so that each bag frame and each dust bag fixed at the bottom of the movable lower frame can move with the movement of the movable lower frame, thereby driving each dust bag to have an up and down amplitude, and can shake off the dust on the outside of each dust bag to a certain extent.

[0021] 3. This kind of pulse bag dust collector, since the flapping driving protrusion can abut the top of the flapping movable rod during the downward rotation process, drive the flapping movable rod and the flapping driving rod to overcome the elastic force of the flapping return spring to move downward, and then drive the entire flapping driving frame to drive each top driving frame to approach one side of the bottom fixed frame through each driving connecting rod, and can simultaneously drive the flapping follower rod to move up and down as the spacing between the top driving frame and the bottom fixed frame changes, and then drive the flapping block to move toward the side close to the dust bag, so that the dust bag can be driven to deform outward, and in the process of the flapping driving protrusion rotating upward, the flapping return spring is restored, driving the flapping movable rod and the flapping driving rod to move upward and reset, thereby driving the flapping block to move to the side away from the dust bag and reset, so that the dust bag can be deformed on the outside of the bag frame to generate horizontal vibration, so as to effectively shake off the dust on the outside of each dust bag.

[0022] 4. This type of pulse bag dust collector has a smaller distance between the end of the frame pressing protrusion away from the driving wheel and the driving wheel than the distance between the end of the flapping driving protrusion away from the driving wheel and the driving wheel. Therefore, each dust bag that reciprocates up and down with the movable lower frame has an up and down amplitude. At the same time, the flapping block that reciprocates and contracts with the up and down reciprocating movement of the flapping driving frame drives each dust bag to have a horizontal amplitude, and the amplitude of the up and down amplitude can be significantly smaller than the horizontal amplitude, thereby effectively preventing dust from being lifted up, thereby effectively separating the dust from the outside of each dust bag and dropping it into the dust collecting chamber for collection, thereby ensuring the purification rate of the dust bag.

[0040] During specific use, the gas inlet 11 of the pulse bag dust collector can be connected to the airflow that needs to be dusted through a pipeline, and the dust-containing gas enters the air inlet chamber 12 from the gas inlet 11.

The driving motor 511 is fixed at the top of the fixed upper frame 411, and the driving wheel 512 is coaxially fixed with the output shaft of the driving motor 511; a frame pressing protrusion 513 and a beating driving protrusion 514 are arranged on one side of the driving wheel 512, and under the drive of the driving motor 511, the frame pressing protrusion 513 and the beating driving protrusion 514 can both rotate with the driving wheel 512; the distance between the end of the frame pressing protrusion 513 away from the driving wheel 512 and the driving wheel 512 is smaller than the distance between the end of the beating driving protrusion 514 away from the driving wheel 512 and the driving wheel 512.

[0044] The cloth bag cleaning mechanism 5 also includes a frame driving unit 53, which can drive the movable lower frame 412 to reciprocate up and down during the rotation of the frame pressing protrusion 513; the frame driving unit 53 includes a frame fixed cylinder 531 and a frame movable rod 532, the frame fixed cylinder 531 is fixed to the fixed upper frame 411, and the frame movable rod 532 can move up and down inside the frame fixed cylinder 531; the bottom end of the frame movable rod 532 is elastically connected to the frame fixed cylinder 531 through a frame return spring 533, and a frame driving rod 534 is provided at the bottom end of the frame movable rod 532, the frame driving rod 534 passes through the bottom end of the frame fixed cylinder 531, and the end of the frame driving rod 534 away from the frame movable rod 532 is fixed to the movable lower frame 412.

[0045] The flapping unit 52 includes a top driving frame 521 and a bottom fixed frame 522, the top driving frame 521 is movably arranged at the inner top of the cloth bag frame 42, and the bottom fixed frame 522 is fixedly arranged at the inner bottom of the cloth bag frame 42; a plurality of flapping follower rods 523 are arranged between the top driving frame 521 and the bottom fixed frame 522, and the flapping follower rods 523 can move up and down with the change of the spacing between the top driving frame 521 and the bottom fixed frame 522; flapping rods 524 are rotatably connected at both ends of the flapping follower rods 523, and the two flapping rods 524 are rotatably connected between the ends away from the flapping follower rods 523 by a flapping shaft 525, and a flapping block 526 is arranged on the side of the flapping shaft 525 close to the dust removal bag 43.

[0046] The cloth bag cleaning mechanism 5 also includes a flapping drive unit 54, which can drive the flapping unit 52 to reciprocate and extend inside the cloth bag frame 42 during the rotation of the flapping drive protrusion 514; the flapping drive unit 54 includes a flapping drive frame 541, and the bottom end of the flapping drive frame 541 is fixed to each top drive frame 521 through a driving connecting rod 542.

[0047] The flapping drive unit 54 also includes a flapping fixed cylinder 543 and a flapping movable rod 544. The flapping fixed cylinder 543 is fixed to the fixed upper frame 411, and the flapping movable rod 544 can move up and down inside the flapping fixed cylinder 543; the bottom end of the flapping movable rod 544 is elastically connected to the flapping fixed cylinder 543 through a flapping return spring 545, and a flapping drive rod 546 is provided at the bottom end of the flapping movable rod 544. The flapping drive rod 546 passes through the flapping fixed cylinder 543, and the flapping drive rod 546 is fixed between the end away from the flapping movable rod 544 and the flapping drive frame 541.

[0048] When it is used in practice, when it is necessary to clean the dust bags 43 outside each bag frame 42, the driving wheel 512 can be driven to rotate by the output shaft of the driving motor 51, and the frame pressing protrusion 513 and the slapping driving protrusion 514 can rotate with the driving wheel 512; at this time, since the frame pressing protrusion 513 can abut against the top of the frame movable rod 532 during the downward rotation, the frame movable rod 532 and the frame driving rod 534 are driven to overcome the elastic force of the frame return spring 533 and move downward, and the frame pressing protrusion 513 and the slapping driving protrusion 514 are driven to abut against the top of the frame movable rod 532 during the downward rotation. During the upward rotation, the frame return spring 533 returns to its original position, driving the frame movable rod 532 and the frame drive rod 534 to move upward and return to their original position, and continuously drives the movable lower frame 412 to reciprocate up and down, thereby enabling each bag frame 42 and each dust bag 43 fixed at the bottom of the movable lower frame 412 to move along with the movement of the movable lower frame 412, thereby driving each dust bag 43 to have an up and down amplitude, and being able to shake off the dust on the outside of each dust bag 43 to a certain extent; similarly, due to the slapping driving protrusion 5 During the downward rotation, the flapping movable rod 544 can be abutted against the top end of the flapping movable rod 544, driving the flapping movable rod 544 and the flapping driving rod 546 to overcome the elastic force of the flapping return spring 545 and move downward, thereby driving the entire flapping driving frame 541 to drive each top driving frame 521 to approach one side of the bottom fixed frame 522 through each driving connecting rod 542, and simultaneously driving the two flapping follower rods 523 to approach each other as the distance between the top driving frame 521 and the bottom fixed frame 522 changes, thereby driving the flapping block 526 to approach One side of the dust bag 43 moves, thereby driving the dust bag 43 to deform outward, and when the flapping driving protrusion 514 rotates upward, the flapping return spring 545 returns, driving the flapping movable rod 544 and the flapping driving rod 546 to move upward and reset, thereby driving the flapping block 526 to move and reset to the side away from the dust bag 43, thereby enabling the dust bag to deform on the outside of the bag frame 42 and generate horizontal vibration, thereby effectively shaking off the dust on the outside of each dust bag 43.

[0049] In actual use, since the distance between the end of the frame pressing protrusion 513 away from the driving wheel 512 and the driving wheel 512 is smaller than the distance between the end of the flapping driving protrusion 514 away from the driving wheel 512 and the driving wheel 512, the dust bags 43 that reciprocate up and down with the movable lower frame 412 have an up and down amplitude. At the same time, the flapping block 526 that reciprocates and extends and reciprocates with the up and down reciprocating movement of the flapping driving frame 541 drives each dust bag 43 to have a horizontal amplitude, and the amplitude of the up and down amplitude can be significantly smaller than the horizontal amplitude, thereby effectively avoiding the dust from being lifted up, so that the dust can be effectively detached from the outside of each dust bag 43 and fall into the dust collecting chamber 15 for collection, thereby ensuring the purification rate of the dust bag 43.

[0050] Embodiment three:

[0051] See also Figure 1-Figure 8 , which is different from the above-mentioned embodiment, is that a baffle cleaning unit 21 is arranged on the outer side of the isolation baffle 2, and the baffle cleaning unit 21 includes two cleaning brushes 211, which are respectively arranged on both sides of the isolation baffle 2, and the two cleaning brushes 211 are connected by a driven connecting rod 212, and the driven connecting rod 212 is arranged on one side of the dust removal chamber 13 and is provided with a driven plate 213, and a driven gear 214 is arranged on one side of the driven plate 213, and the driven gear 214 is gear-engaged with the driven plate 213, and a gear motor is arranged on one side of the driven gear, and the gear motor can drive the two cleaning brushes 211 to reciprocate up and down through the driven gear 214 to clean the two side surfaces of the isolation baffle 2.

[0052] Therefore, when in use, the cleaning of the isolation baffle 2 driven by the gear motor can be synchronized with the cleaning of the dust bag driven by the drive motor 511. When in use, the gear motor rotates through the driven gear 214, thereby driving the driven plate 213 meshing with the driven gear 214 to reciprocate up and down, and then driving the two cleaning brushes 211 connected and fixed to the driven plate 213 through the driven connecting rod 212 to reciprocate up and down, so that the two side surfaces of the isolation baffle 2 can be cleaned synchronously, thereby ensuring the dust removal efficiency of the entire pulse bag dust collector.

[0053] A collecting drawer 151 is provided at the bottom end of the dust collecting chamber 15, and the collecting drawer 151 can collect the dust falling into the dust collecting chamber 15; an air collecting cylinder 141 and a two-way fan 142 are provided at the top end of the exhaust chamber 14, and the air collecting cylinder 141 can guide and discharge the gas entering the exhaust chamber 14 from the dust removal chamber 13, and the two-way fan 142 can change the direction of the airflow and can reverse the air intake into the dust removal chamber 13; the bag frame 42 includes a plurality of connecting rings 421 and a plurality of connecting rods 422, and each connecting rod 422 is welded and fixed to each connecting ring 421, and a fixing buckle is provided on the connecting point between each connecting rod 422 and each connecting ring 421, and the inside of the dust removal bag 43 and the bag frame 42 can be temporarily fixed by the fixing buckle.

[0054] Therefore, during specific use, the dust falling into the dust collecting chamber 15 can be collected through the collecting drawer 151, and the collecting drawer 151 can be taken out for cleaning, and the direction of the airflow can be changed periodically by the two-way fan 142, so that the air can be reversely introduced into the dust removal chamber 13, and the dust embedded in the dust bag 43 can be blown out in the opposite direction, thereby ensuring the dust removal rate of the dust bag 43, and after completing a stage of dust removal work, the dust bag 43 temporarily fixed by the fixing buckle can be detached from the bag frame 42, and the dust bag 43 can be replaced or deeply cleaned.

[0055] Embodiment 4:

[0056] A dust removal method for feed processing, using a pulse bag dust collector as described in any one of Embodiments 1 to 3, comprises the following steps:

[0057] The dust-containing gas generated during feed processing enters the air inlet 11 into the air inlet chamber 12, a part of which can pass through the isolation baffle 2 and enter the dust removal chamber 13, and the other part can bypass the isolation baffle 2 and enter the dust removal chamber 13 from the exhaust chamber 14;

[0058] The dust-laden gas passes through the dust removal bags 43 of the dust removal chamber 13, and the dust in the dust-laden gas can be trapped on the outer surface of the dust removal bag 43 by the dust removal bag 43, and the gas in the dust-laden gas can pass through the dust removal bag 43 and the exhaust baffle 3 into the exhaust chamber 14 for discharge;

[0059] At regular intervals, the beating unit 52 can be driven by the cleaning drive unit 51 to reciprocate and extend inside the bag frame 42. When the beating unit 52 extends from the bag frame 42, the dust removal bag 43 mounted on the outside of the bag frame 42 is driven to vibrate under its own elasticity, and the dust on the outer surface of the dust removal bag 43 is shaken off into the dust collecting chamber 15, thereby completing the cleaning process of each dust removal bag 43, effectively restoring the dust removal effect of each dust removal bag 43, and avoiding interruption of dust removal work to ensure the continuous dust removal work.

[0060] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
