Description

Technical Field

[0001] This invention relates to the field of dust removal technology in feed processing, specifically to a pulse bag filter, dust removal method, and feed processing technology. Background Art

[0002] A pulse jet baghouse dust collector is a highly efficient baghouse dust collection device widely used in industrial production for dust collection and gas purification. It filters dust-laden gas through filter bags and uses pulse jet cleaning technology to remove dust from the filter bags, thereby purifying the air. Pulse jet baghouse dust collectors have advantages such as large air volume handling capacity, good dust removal effect, high dust collection efficiency, reliable operation, and convenient maintenance. The working principle of a pulse jet baghouse dust collector is as follows: Dust-laden gas first passes through a dust hopper, where larger dust particles fall directly into the hopper, while finer dust particles are carried by the airflow into the filter chamber. Inside the filter chamber, the dust is trapped by the filter bags, and the purified gas passes through the filter bags into the upper housing and is discharged through the exhaust pipe. As filtration time increases, the dust layer on the filter bags gradually thickens, causing the equipment resistance to rise. When the resistance reaches a set value, the dust removal control device activates the pulse jet cleaning system, using compressed air to blow air through the filter bags, causing them to expand and shake off the dust, restoring the filter bags' filtration capacity.

[0003] To ensure the efficient operation of pulse jet baghouse dust collectors, regular maintenance and inspections are necessary. These inspections include checking the integrity of the filter bags, the operational status of the cleaning system, and the accuracy of the control system. Optimizing operating parameters, such as filtration velocity and cleaning cycle, is also a crucial measure to improve dust removal efficiency and reduce operating costs.

[0004] Existing baghouse dust collectors, especially miniaturized ones, have short cleaning cycles due to size limitations. As a result, dust quickly clogs the bags and filters during feed processing, causing processing to be interrupted. This makes it difficult to meet the needs of continuous processing and cost savings in cleaning. Summary of the Invention

The dust-laden gas enters the air inlet chamber from the gas inlet. Part of it can pass through the isolation baffle and enter the dust collection chamber, while another part can bypass the isolation baffle and enter the dust collection chamber from the exhaust chamber. The dust-laden gas passes through each of the dust collector bags in the dust collection chamber. The dust in the dust-laden gas can be trapped on the outer surface of the dust collector bags.

[0016] A dust removal method for feed processing, using the aforementioned pulse bag filter, includes the following steps: Dust-laden gas enters the inlet chamber from the gas inlet; a portion passes through the isolation baffle and enters the dust removal chamber, while another portion bypasses the isolation baffle and enters the dust removal chamber; the dust-laden gas passes through each dust collector bag in the dust removal chamber, and the dust in the dust-laden gas is trapped on the outer surface of the dust collector bags; the gas in the dust-laden gas passes through the dust collector bags and the exhaust baffle and enters the exhaust chamber for discharge; at regular intervals, the tapping unit reciprocates inside the bag frame under the drive of the cleaning drive unit; when the tapping unit extends from inside the bag frame, it drives the dust collector bags fitted on the outside of the bag frame to vibrate under their own elasticity, shaking the dust on the outer surface of the dust collector bags into the dust collection chamber.

[0017] A feed processing technology is characterized by the use of the aforementioned pulse bag filter.

[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 type of pulse bag filter dust collector, when dust-laden gas passes through the isolation baffle, some dust in the gas can be trapped by the isolation baffle and adhere to the surface of the isolation baffle. Due to the flow of dust-laden gas, when the dust-laden gas passes through each dust collector bag in the dust collection chamber, the dust in the gas can be trapped on the outer surface of the dust collector bag. 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 dust and gas in the dust-laden gas. Then, when needed, the tapping unit reciprocates inside the bag frame under the drive of the cleaning drive unit. When the tapping unit extends from inside the bag frame, it drives the dust collector bag sleeved on the outside of the bag frame to vibrate under its own elasticity, shaking the dust on the outer surface of the dust collector bag to the dust collection chamber, thereby completing the cleaning process of each dust collector bag, effectively restoring the dust collection effect of each dust collector bag, and avoiding the interruption of dust collection work to ensure continuous dust collection.

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

[0021] 3. In this type of pulse bag dust collector, the tapping drive protrusion abuts against the top of the tapping movable rod during downward rotation, driving the tapping movable rod and the tapping drive rod to move downward against the elastic force of the tapping return spring. This, in turn, drives the entire tapping drive frame to move the top drive frames closer to the bottom fixed frame via various drive linkages. Simultaneously, it drives the tapping follower rod to move up and down according to the change in the distance between the top drive frame and the bottom fixed frame, thereby driving the tapping block to move closer to the dust collector bag. This causes the dust collector bag to deform outward. During the upward rotation of the tapping drive protrusion, the tapping return spring returns, driving the tapping movable rod and the tapping drive rod to move upward and reset. This causes the tapping block to move away from the dust collector bag and reset, allowing the dust collector bag to deform on the outside of the bag frame and generate horizontal vibration, effectively shaking off the dust on the outside of each dust collector bag.

[0022] 4. In this type of pulse bag dust collector, because the distance between the end of the frame pressing protrusion away from the drive wheel and the drive wheel is smaller than the distance between the end of the striking drive protrusion away from the drive wheel and the drive wheel, the dust collector bags that reciprocate with the up-and-down movement of the movable lower frame have vertical amplitudes, while the striking blocks that reciprocate with the up-and-down movement of the striking drive frame drive the dust collector bags to have horizontal amplitudes. This makes the vertical amplitude significantly smaller than the horizontal amplitude, thereby effectively preventing dust from being thrown upwards. As a result, dust can be effectively detached from the outside of each dust collector bag and fall into the dust collection chamber for collection, ensuring the purification rate of the dust collector bags.

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes a pulse bag dust collector, a dust removal method, and a feed processing technology.

[0038] Example 1:

[0039] Please see Figures 1-12A pulse jet baghouse dust collector includes a mounting housing 1, a gas inlet 11 on one side of the mounting housing 1, an isolation baffle 2 inside the mounting housing 1 near the gas inlet 11, an exhaust baffle 3 at the top of the isolation baffle 2, and the mounting housing 1 is divided into an air inlet chamber 12, a dust collection chamber 13, and an exhaust chamber 14 by the isolation baffle 2 and the exhaust baffle 3. A dust collection chamber 15 is located inside the mounting housing 1 at the bottom of the isolation baffle 2 and the dust collection chamber 13. A baghouse dust collection mechanism 4 is installed inside the dust collection chamber 13. A mounting frame 41 is installed at the top of the baghouse dust collection mechanism 4, and several bag frames 42 are installed at the bottom of the mounting frame 41. Each bag frame 42 is fitted with a dust collection bag 43. A bag cleaning mechanism 5 is installed at the top of the mounting frame 41. The bag cleaning mechanism 5 includes a cleaning drive. The moving unit 51 and the beating unit 52 are driven by the cleaning drive unit 51 to reciprocate inside the bag frame 42. When the beating unit 52 extends out of the bag frame 42, it drives the dust collector bag 43, which is sleeved on the outside of the bag frame 42, to vibrate under its own elasticity, shaking the dust on the outer surface of the dust collector bag 43 to fall into the dust collection chamber 15. The dust-laden gas enters the air intake chamber 12 from the gas inlet 11. Part of it can pass through the isolation baffle 2 and enter the dust collection chamber 13, and the other part can bypass the isolation baffle 2 and enter the dust collection chamber 13. The dust-laden gas passes through each dust collector bag 43 in the dust collection chamber 13. The dust in the dust-laden gas can be trapped on the outer surface of the dust collector bag 43. The gas in the dust-laden gas can pass through the dust collector bag 43 and the exhaust baffle 3 and enter the exhaust chamber 14.

[0040] In practical use, the gas inlet 11 of this pulse bag dust collector can be connected to the airflow requiring dust removal via a pipe. Dust-laden gas enters the inlet chamber 12 from the gas inlet 11. Due to the isolation baffle 2, most of the dust-laden gas passes through the isolation baffle 2 and enters the dust removal chamber 13. As the dust-laden gas passes through the isolation baffle 2, some dust in the gas is trapped by the isolation baffle 2 and adheres to its surface. A small portion of the dust-laden gas bypasses the isolation baffle 2 and enters the dust removal chamber 13, causing the dust-laden gas to converge inside the dust removal chamber 13 and outside each dust collector bag 43. Due to the flow of the dust-laden gas, the dust in the gas is removed as it passes through each dust collector bag 43 in the dust removal chamber 13. The dust bag 43 is trapped on its outer surface. The gas in the dust-laden gas can pass through the dust bag 43 and the exhaust baffle 3 and enter the exhaust chamber 14, thereby completing the separation of dust and gas in the dust-laden gas. In actual use, the tapping unit 52 reciprocates inside the bag frame 42 under the drive of the cleaning drive unit 51. When the tapping unit 52 extends out of the bag frame 42, it drives the dust bag 43 sleeved on the outside of the bag frame 42 to vibrate under its own elasticity, shaking the dust on the outer surface of the dust bag 43 to fall into the dust collection chamber 15. This completes the cleaning process of each dust bag 43, effectively restores the dust removal effect of each dust bag 43, and avoids the interruption of dust removal work, ensuring the continuous operation of dust removal work.

[0041] Example 2:

[0042] Please see Figures 1-2 , Figures 6-12 The difference from the above embodiment is that the mounting frame 41 includes a fixed upper frame 411 and a movable lower frame 412. The fixed upper frame 411 is fixed to the inner wall of the mounting housing 1. The fixed upper frame 411 and the movable lower frame 412 are elastically connected by a number of frame springs 413. Each bag frame 42 is fixed to the movable lower frame 412, and each bag frame 42 can move with the movement of the movable lower frame 412.

[0043] The cleaning drive unit 51 includes a drive motor 511 and a drive wheel 512. The drive motor 511 is fixed to the top of the fixed upper frame 411, and the drive wheel 512 is coaxially fixed with the output shaft of the drive motor 511. A frame pressing protrusion 513 and a tapping drive protrusion 514 are provided on one side of the drive wheel 512. Under the drive of the drive motor 511, both the frame pressing protrusion 513 and the tapping drive protrusion 514 can rotate with the drive wheel 512. The distance between the end of the frame pressing protrusion 513 away from the drive wheel 512 and the drive wheel 512 is smaller than the distance between the end of the tapping drive protrusion 514 away from the drive wheel 512 and the drive wheel 512.

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

[0045] The tapping unit 52 includes a top drive frame 521 and a bottom fixed frame 522. The top drive frame 521 is movably disposed inside the top of the bag frame 42, and the bottom fixed frame 522 is fixedly disposed inside the bottom of the bag frame 42. A plurality of tapping follower rods 523 are disposed between the top drive frame 521 and the bottom fixed frame 522. The tapping follower rods 523 can move up and down as the distance between the top drive frame 521 and the bottom fixed frame 522 changes. Tapping rods 524 are rotatably connected to both ends of the tapping follower rods 523. The ends of the two tapping rods 524 away from the tapping follower rods 523 are rotatably connected by a tapping shaft 525. A tapping block 526 is disposed on the side of the tapping shaft 525 near the dust collector bag 43.

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

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

[0048] In practical use, when it is necessary to clean the dust collector bags 43 on the outside of each bag frame 42, the output shaft of the drive motor 51 can drive the drive wheel 512 to rotate, and the frame pressing protrusion 513 and the tapping drive protrusion 514 can also rotate with the drive 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 drive rod 534 are driven to overcome the elastic force of the frame return spring 533 and move downward, and the frame pressing protrusion 513 abuts against the top of the frame movable rod 532 during the downward rotation. 3. During the upward rotation, the frame return spring 533 returns, driving the frame movable rod 532 and frame drive rod 534 to move upward and reset, continuously driving the movable lower frame 412 to move up and down reciprocally. This causes the bag frames 42 and the dust collector bags 43 fixed at the bottom of the movable lower frame 412 to move with the movement of the movable lower frame 412, thereby driving the dust collector bags 43 to have up and down amplitude, which can shake off the dust on the outside of the dust collector bags 43 to a certain extent; similarly, due to the tapping drive protrusion 5 14 During downward rotation, it can abut the top of the striking movable rod 544, driving the striking movable rod 544 and the striking drive rod 546 to overcome the elastic force of the striking return spring 545 and move downward. This, in turn, drives the entire striking drive frame 541 to move each top drive frame 521 closer to one side of the bottom fixed frame 522 through each drive linkage 542. Simultaneously, it can drive the two striking follower rods 523 to approach each other as the distance between the top drive frame 521 and the bottom fixed frame 522 changes, thereby driving the striking block 526 to move closer. The dust collector bag 43 moves to one side, thereby driving the dust collector bag 43 to deform outward. During the upward rotation of the tapping drive protrusion 514, the tapping return spring 545 returns, driving the tapping movable rod 544 and the tapping drive rod 546 to move upward and reset. This drives the tapping block 526 to move away from the dust collector bag 43 and reset, so that the dust collector bag can 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 collector bag 43.

[0049] In actual use, since the distance between the end of the frame pressing protrusion 513 away from the drive wheel 512 and the drive wheel 512 is smaller than the distance between the end of the tapping drive protrusion 514 away from the drive wheel 512 and the drive wheel 512, the dust collector bags 43 that move up and down with the movable lower frame 412 have vertical amplitudes, while the tapping block 526 that moves up and down with the tapping drive frame 541 drives the dust collector bags 43 to have horizontal amplitudes. The vertical amplitude is significantly smaller than the horizontal amplitude, which effectively prevents dust from being thrown up. This effectively removes dust from the outside of each dust collector bag 43 and collects it inside the dust collection chamber 15, ensuring the purification rate of the dust collector bags 43.

[0050] Example 3:

[0051] Please see Figures 1-8 The difference from the above embodiment is that a baffle cleaning unit 21 is provided on the outer side of the isolation baffle 2. The baffle cleaning unit 21 includes two cleaning brushes 211, which are respectively arranged on both sides of the isolation baffle 2. The two cleaning brushes 211 are connected by a driven connecting rod 212. A driven plate 213 is provided on one side of the dust removal chamber 13, and a driven gear 214 is provided on one side of the driven plate 213. The driven gear 214 meshes with the driven plate 213. A gear motor is provided on one side of the driven gear, which can drive the two cleaning brushes 211 to move up and down reciprocally through the driven gear 214 to clean the two sides of the isolation baffle 2.

[0052] Therefore, during use, the cleaning of the isolation baffle 2 driven by the gear motor can be synchronized with the cleaning of the dust collector bag driven by the drive motor 511. During use, the gear motor rotates through the driven gear 214, which in turn drives the driven plate 213, which meshes with the driven gear 214, to move up and down reciprocally. This, in turn, drives the two cleaning brushes 211, which are connected and fixed to the driven plate 213 through the driven connecting rod 212, to move up and down reciprocally. This allows for the synchronous cleaning of both sides of the isolation baffle 2, thereby ensuring the dust removal efficiency of the entire pulse bag dust collector.

[0053] The dust collection chamber 15 has a collection drawer 151 at the bottom, which can collect the dust that falls into the dust collection chamber 15. The exhaust chamber 14 has an air collection cylinder 141 and a bidirectional fan 142 at the top. The air collection cylinder 141 can guide the gas entering the exhaust chamber 14 from the dust collection chamber 13 to be discharged. The bidirectional fan 142 can change the direction of airflow and can reverse the air intake into the dust collection chamber 13. The bag frame 42 includes several connecting rings 421 and several connecting rods 422. Each connecting rod 422 is welded and fixed to each connecting ring 421. A fixing buckle is provided at the connection point between each connecting rod 422 and each connecting ring 421. The dust collector bag 43 can be temporarily fixed to the bag frame 42 by the fixing buckle.

[0054] In practical use, the dust falling into the dust collection chamber 15 can be collected by the collection drawer 151, and the collection drawer 151 can be taken out for cleaning. The direction of airflow can be changed by the bidirectional fan 142 at regular intervals, which can reverse the air intake into the dust removal chamber 13 and blow out the dust embedded in the dust removal bag 43 in the opposite direction, thus ensuring the dust removal rate of the dust removal bag 43. After completing a stage of dust removal work, the dust removal bag 43, which is temporarily fixed by the fixing buckle, can be detached from the bag frame 42, so that the dust removal bag 43 can be replaced or deep cleaned.

[0055] Example 4:

[0056] A dust removal method for feed processing, using a pulse bag filter as described in any one of Examples 1-3, includes the following steps:

[0057] Dust-laden gas generated during feed processing enters the air inlet 12 through the gas inlet 11. Part of it can pass through the isolation baffle 2 and enter the dust removal chamber 13, while the other part can bypass the isolation baffle 2 and enter the dust removal chamber 13.

[0058] Dust-laden gas passes through each dust collector bag 43 in the dust collection chamber 13. Dust in the dust-laden gas can be trapped on the outer surface of the dust collector bags 43. The gas in the dust-laden gas can pass through the dust collector bags 43 and the exhaust baffle 3 and enter the exhaust chamber 14 for discharge.

[0059] At regular intervals, the tapping unit 52 can reciprocate inside the bag frame 42 under the drive of the cleaning drive unit 51. When the tapping unit 52 extends out of the bag frame 42, it drives the dust collector bag 43, which is sleeved on the outside of the bag frame 42, to vibrate under its own elasticity, shaking the dust on the outer surface of the dust collector bag 43 into the dust collection chamber 15. This completes the cleaning process of each dust collector bag 43, effectively restores the dust removal effect of each dust collector bag 43, and avoids the interruption of dust removal work, ensuring the continuous operation of dust removal work.
