Description

Technical Field

[0001] This invention relates to the field of dust removal technology in feed production, specifically to an online automatic dust removal pulse dust collector for feed processing. Background Technology

[0002] During feed processing, the crushing, pelleting, and extrusion processes generate a large amount of sticky, dusty exhaust gas containing mixed oils and molasses. The dust in the exhaust gas is highly sticky, and conventional external filter pulse dust collectors rely solely on filter bags to intercept the dust. The dust easily forms a dense dust cake on the outer wall of the filter bag, causing the filter bag's operating resistance to rise rapidly, increasing the fan's energy consumption. Furthermore, the thick dust cake is difficult to clean, frequently leading to bag clogging and failure.

[0003] Patent CN121197921B discloses a pulse-jet dust collector for feed production and processing. This dust collector is equipped with a pulse cooling component and an air-guiding hardening component. Compressed air is first sent to the pulse cooling component, where it is cooled by a semiconductor cooling chip and a spiral tube. Then, moisture is removed from the cooled air by a multi-stage moisture-absorbing component. The low-temperature, dry compressed air is then sent to a compression tank to supply the pulse jet cleaning mechanism. Simultaneously, a portion of the cooling air is diverted and transported to a hollow support box below the filter bag via a turbocharger pump. This drives a rotating ring and a blower arc plate to rotate along the outer wall of the filter bag, providing secondary cooling and hardening of the dust in the blind spots covered by the pulse airflow. A vibration component is fitted at the bottom of the blower arc plate, and a vibration motor drives a vibration ring to shake the filter bag, dislodging the hardened and brittle dust. This reduces the adhesion between sticky dust and the filter bag, improving the pulse cleaning effect.

[0004] Although the above solutions improve the problem of sticky dust clogging the bags by hardening the dust with cooling air and using bottom auxiliary air cooling and vibration combined cleaning, the dust collectors in the above solutions can only carry out centralized cleaning intermittently after a large amount of dust has accumulated to form a thick dust cake. They cannot reduce the dust layer on the surface of the filter bags in real time under normal filtration conditions, and the filter bags are in a high-resistance operating state for a long time. Summary of the Invention

[0016] The advantages of this invention compared to the prior art are:

[0017] 1. This invention comprises a dust collector housing, filter bags, a pulse structure, a dust removal mechanism, and a drive assembly. Dust-laden exhaust gas from feed is introduced through the side inlet of the dust collector housing. The airflow passes through the filter bags from the outside in, and dust adheres to the outer surface of the filter bags. Clean air is discharged from the top outlet of the dust collector housing. When the equipment filters dust-laden exhaust gas, the drive assembly outputs two sets of power. One set drives the annular frame of the dust removal mechanism to reciprocate up and down along the filter bags. The synchronously rising and falling pulse structure releases pulse airflow to open the filter bags and make them fit the cleaning components. The other set drives the cleaning components to rotate and scrape off the dust on the outer wall of the filter bags. The detached dust falls into the dust collection and discharge components for collection and transportation. Cleaning and filtration are carried out simultaneously, thereby maintaining the filter bags in a low-resistance operating state for a long time.

[0018] 2. This invention is equipped with two airtight air curtain barrier units and an air supply pipe. When the equipment simultaneously performs dust-laden waste gas filtration and dust removal operations, the air supply pipe delivers clean airflow to the two airtight air curtain barrier units at the top and bottom of the annular frame. The two sets of airtight air curtain barrier units are fixed at the upper and lower ends of the annular frame, respectively. The airtight air curtain barrier units spray out a continuous airflow barrier that is obliquely aimed at the filter bag, blocking the unfiltered dust-laden waste gas in the dust collector box. The waste gas cannot pass through the gap between the annular frame and the filter bag to enter the interior of the annular frame. The airflow barrier separates the high-temperature viscous waste gas from the internal components of the dust removal mechanism throughout the process, thereby reducing the adhesion and accumulation of sticky dust on the inner wall of the cleaning components.

[0019] 3. This invention is equipped with an annular base, an annular blade holder, and multiple blades. The drive assembly outputs power to drive the annular blade holder to rotate around the axis of the annular base. The blades installed in the slots of the annular blade holder rotate synchronously along the circumferential direction of the outer wall of the filter bag. The blade surfaces are in contact with the outer surface of the filter bag and scrape off the deposited feed dust. The dust after being peeled off falls to the dust collection and discharge assembly below the annular blade holder by gravity. The blades can completely cover the entire outer wall of the filter bag with a small rotation, thereby shortening the running time of a single circumferential cleaning of the filter bag.

[0033] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0034] Reference Figures 1 to 12As shown: An online automatic dust removal pulse dust collector for feed processing includes a dust collector housing 1, multiple filter bags 2 arranged in a matrix inside the dust collector housing 1, and a pulse structure 3 disposed inside the filter bags 2 and capable of moving up and down along the inner cavity of the filter bags 2. The dust collector housing 1 has an inlet 11 and an outlet 12 on its side and top, respectively. It also includes a dust removal mechanism 4 and a drive assembly 5. There are multiple dust removal mechanisms 4, and each of the multiple dust removal mechanisms 4 corresponds one-to-one with a multiple of the filter bags 2. The dust removal mechanism 4 includes a ring frame 41, a cleaning component 42, and a dust collection and discharge component 43. The ring frame 41 is sleeved on the outside of the filter bags 2, and the ring frame 41 is connected to the drive assembly 5. The components are connected in a 5-way configuration; the cleaning assembly 42 is disposed inside the annular frame 41, and the cleaning assembly 42 can rotate around the axis of the annular frame 41 to clean the debris on the outer surface of the filter bag 2; the dust collection and discharge assembly 43 is disposed below the cleaning assembly 42, the dust collection and discharge assembly 43 is fixed to the annular frame 41 and rises and falls synchronously with it, and the dust collection and discharge assembly 43 is used to collect and transfer debris; the drive assembly 5 is connected to multiple dust removal mechanisms 4, and the drive assembly 5 has two power sources, which are respectively used to drive the annular frame 41 to reciprocate along the filter bag 2 and to drive the cleaning assembly 42 to rotate around the axis of the annular frame 41.

[0035] The dust-laden exhaust gas from the feed is introduced through the inlet 11 on the side of the dust collector 1. The airflow passes through the filter bag 2 from the outside to the inside, and the dust settles on the outer surface of the filter bag 2. The clean air after filtration is discharged from the outlet 12 at the top of the dust collector 1. During the continuous filtration of the dust-laden exhaust gas, the two power sources of the drive assembly 5 output two sets of power respectively. The first set of power drives the annular frame 41 inside the dust sweeping mechanism 4 to reciprocate up and down along the filter bag 2. The pulse structure 3 inside the filter bag 2 moves up and down synchronously and releases pulse airflow continuously. The pulse airflow fills the inner cavity of the filter bag 2 and pushes the filter bag. The bag 2 expands outward and fits the cleaning component 42. The second set of power drives the cleaning component 42 to rotate continuously along the axis of the ring frame 41. The rotating cleaning component 42 scrapes away the dust accumulated on the outer wall of the filter bag 2. The detached dust falls to the dust collection and discharge component 43 below the cleaning component 42 by gravity. The dust collection and discharge component 43 simultaneously completes the dust collection and outward transportation. The cleaning operation and the dust-laden exhaust gas filtration operation are carried out simultaneously without stopping the gas purification. It can continuously clean the newly attached dust on the surface of the filter bag 2, thereby maintaining the low resistance operation state of the filter bag 2 for a long time.

[0036] Reference Figure 3 and Figure 4As shown: The dust removal mechanism 4 also includes an airtight air curtain barrier component 44, which includes two airtight air curtain barrier units 441 and an air supply pipe 442; the two airtight air curtain barrier units 441 are respectively arranged on the upper and lower sides of the annular frame 41, and the airtight air curtain barrier units 441 are used to spray airflow obliquely aligned with the filter bag 2 to form an air curtain barrier; the air supply pipe 442 is connected to the two airtight air curtain barrier units 441 and delivers high-pressure air.

[0037] During the simultaneous operation of dust-laden exhaust gas filtration and dust removal, the air supply pipe 442 continuously delivers clean airflow to the two airtight air curtain barrier units 441 at the top and bottom of the annular frame 41. The two sets of airtight air curtain barrier units 441 are fixed at the upper and lower ends of the annular frame 41, respectively. After the airflow is ejected from the airtight air curtain barrier unit 441, it forms a continuous airflow barrier that is obliquely aligned with the filter bag 2. The dust-laden exhaust gas inside the dust collector 1 that has not yet been filtered will be blocked by this airflow barrier. The exhaust gas cannot pass through the gap between the annular frame 41 and the filter bag 2 and flow into the interior of the annular frame 41. The air curtain can completely isolate the high-temperature exhaust gas containing grease and molasses from the internal components of the dust removal mechanism 4, thereby reducing the adhesion and accumulation of sticky dust on the inner wall of the cleaning component 42.

[0038] Reference Figure 3 and Figure 5 As shown: The cleaning assembly 42 includes an annular base 421, an annular blade holder 422, and multiple blades 423; the annular base 421 is coaxially connected to the annular frame 41; the annular blade holder 422 can rotate around the axis of the annular base 421, and multiple slots are provided on the annular blade holder 422; the multiple blades 423 are respectively inserted into the multiple slots, and the cutting surfaces elastically abut against the outer surface of the filter bag 2.

[0039] The drive assembly 5 transmits power to the annular blade holder 422, which rotates continuously around the axis of the annular base 421. The blades 423, installed inside the slots of the annular blade holder 422, rotate synchronously with the annular blade holder 422 along the circumference of the outer wall of the filter bag 2. The cutting surfaces of the blades 423 are in close contact with the outer surface of the filter bag 2, continuously scraping away the feed dust deposited on the outer wall of the filter bag 2 during uniform rotation. The dust stripped off by the blades 423 falls vertically under its own gravity and is temporarily stored in the dust collection and discharge assembly 43 located below the annular blade holder 422. Multiple blades 423 only need to rotate a small angle to completely cover the entire outer wall of the filter bag 2, completing the full circumference cleaning without significant adjustments to the component positions, thereby shortening the running time for a single circumferential cleaning of the filter bag 2.

[0040] Reference Figure 5 and Figure 6As shown: The lower surface of the annular tool holder 422 is provided with an annular groove 4221, and the annular base 421 is provided with a ball bearing 424, which rolls in cooperation with the groove 4221.

[0041] The lower surface of the annular cutter holder 422 is machined with an annular groove 4221. The ball bearings 424 mounted on the annular base 421 are embedded in the annular groove 4221 to form a rolling fit structure. The drive assembly 5 outputs power to drive the annular cutter holder 422 and the blades 423 in the slot to rotate synchronously to scrape the dust off the outer wall of the filter bag 2. During operation, the ball bearings 424 continuously roll along the annular groove 4221. The ball bearings 424 bear the radial load generated by the rotation of the annular cutter holder 422 and the blades 423, and constrain the radial displacement of the annular cutter holder 422. A fixed contact distance can be maintained between the blades 423 and the outer wall of the filter bag 2. Rolling contact replaces sliding contact, the frictional resistance generated by the rotation of the components decreases, and the driving force required for the rotation of the cleaning assembly 42 is reduced accordingly, thereby reducing the power consumption of the equipment during long-term operation.

[0042] Reference Figure 2 and Figure 7 As shown: The cleaning assembly 42 further includes a gear 425, which is coaxially and fixedly connected to the annular blade holder 422, and the gear 425 is also connected to the drive assembly 5 for transmission.

[0043] Gear 425 and annular cutter holder 422 are coaxially fixedly assembled. After the drive assembly 5 outputs power, it forms a transmission connection with gear 425. The power is directly transmitted to annular cutter holder 422 through gear 425. Annular cutter holder 422 maintains stable rotation by relying on the rolling fit structure formed by annular base 421, ball bearing 424 and annular groove 4221. Blade 423 installed in slot rotates circumferentially along the outer wall of filter bag 2 with annular cutter holder 422. Blade 423 continuously peels off feed dust accumulated on the outer wall of filter bag 2. The peeled dust falls downward under the action of gravity and falls into the dust collection and discharge assembly 43 below cleaning assembly 42 for collection. Gear 425 and annular cutter holder 422 are arranged coaxially, there are no extra intermediate transfer components in the power transmission process, the power transmission path is short, and the power loss in the transmission process is lower.

[0044] Reference Figure 3 and Figure 8 As shown: The dust collection and discharge assembly 43 includes an annular dust collection trough 431; the annular dust collection trough 431 is coaxially arranged below the annular knife holder 422.

[0045] The bottom of the annular integrated tank 431 is provided with a negative pressure suction pipe 432, which is connected to a negative pressure device for suctioning impurities in the annular dust collection tank 431.

[0046] The drive assembly 5 drives the annular frame 41 to move up and down, while the cleaning component 42 rotates synchronously to scrape off the dust adhering to the outer wall of the filter bag 2. The dust stripped off by the blade 423 falls downward under its own gravity and into the annular dust collection trough 431 arranged coaxially below the annular blade holder 422. The annular dust collection trough 431 is connected to an external negative pressure device through a negative pressure suction pipe 432. The negative pressure device operates continuously, forming a stable negative pressure environment inside the annular dust collection trough 431. The dust in the annular dust collection trough 431 is simultaneously subjected to the dual effects of gravity and negative pressure suction, continuously flowing into the negative pressure suction pipe 432 for outward transfer. The dust cannot accumulate and clump inside the annular dust collection trough 431. The two forces work simultaneously to continuously remove the dust from the annular dust collection trough 431, thereby preventing dust accumulation inside the annular dust collection trough 431 and ensuring continuous dust discharge.

[0047] Reference Figure 8 As shown: The dust collection and discharge assembly 43 also includes a scraper 433, which is used to push the impurities in the annular dust collection trough 431 to move, and the scraper 433 is connected to the annular knife holder 422.

[0048] The drive assembly 5 drives the annular blade holder 422 to rotate. The blades 423 inside the slot simultaneously scrape off the dust adhering to the outer wall of the filter bag 2. The scraper 433, which is fixedly connected to the annular blade holder 422, rotates synchronously around the axis of the filter bag 2. The scraper 433 continuously pushes the dust settled inside the annular dust collection trough 431 towards the air inlet of the negative pressure suction pipe 432. The external negative pressure equipment continues to work, forming a negative pressure adsorption force inside the annular dust collection trough 431 through the negative pressure suction pipe 432. The scraper 433 pushes the dust and the adsorption effect of the negative pressure suction pipe 432 work in sync to continuously transport the dust in the annular dust collection trough 431 outward. The dust in the annular dust collection trough 431 will not accumulate or stagnate. The scraper 433 continuously disturbs the dust accumulated in the annular dust collection trough 431 and guides the dust to the suction point, thereby improving the efficiency of dust discharge from the annular dust collection trough 431.

[0049] Reference Figure 4 and Figure 9 As shown: The airtight air curtain barrier unit 441 includes multiple air jet pipes 4411 and multiple universal bases 4412; the multiple air jet pipes 4411 are arranged in a ring array around the filter bag 2; the multiple universal bases 4412 correspond one-to-one with the multiple air jet pipes 4411, and the universal bases 4412 are used to adjust the orientation of the air jet pipes 4411.

[0050] The air supply pipe 442 continuously supplies airflow to the airtight air curtain barrier units 441 on the upper and lower sides of the annular frame 41. In a single airtight air curtain barrier unit 441, multiple jet pipes 4411 are arranged in a ring array with the filter bag 2 as the center. Each jet pipe 4411 is equipped with an independent universal base 4412. The operator can adjust the airflow spray angle of the corresponding jet pipe 4411 by rotating the universal base 4412. After the angle adjustment is completed, all jet pipes 4411 simultaneously spray airflow obliquely aimed at the filter bag 2. Multiple airflows are connected to each other, forming a seamless annular airflow barrier between the annular frame 41 and the filter bag 2. The dust-laden exhaust gas inside the box cannot pass through the barrier and enter the interior of the annular frame 41. Multiple jet pipes 4411 can adjust their spray angles individually and then work together to discharge air. The airflow can be seamlessly connected to form a sealed shielding structure, thereby completely blocking the passage of dust-laden exhaust gas into the dust removal mechanism 4.

[0051] Reference Figure 10 and Figure 11 As shown: The drive assembly 5 includes a connecting box 51 and a synchronous rotation mechanism 52; the connecting box 51 is provided with a partition 511 inside, which divides the inner cavity of the connecting box 51 into a drive cavity 512 and an air supply cavity 513. The air supply cavity 513 is connected to the air supply pipe 442 and is used to supply air to the airtight air curtain barrier unit 441; the synchronous rotation mechanism 52 is disposed in the drive cavity 512 and is used to drive the gear 425 to rotate.

[0052] Specifically, the synchronous rotation mechanism 52 includes an external gear ring 521 and a first rotation driver 522. The external gear ring 521 meshes with all gears 425, and the first rotation driver 522 is used to drive the external gear ring 521 to rotate.

[0053] The partition 511 divides the inner cavity of the connecting box 51 into a drive chamber 512 and an air supply chamber 513. The air supply pipe 442 is connected to the air supply chamber 513 to complete the airflow delivery operation. The drive chamber 512 is equipped with a synchronous rotation mechanism 52. The first rotary driver 522 inside the synchronous rotation mechanism 52 drives the external gear ring 521 to rotate continuously. The external gear ring 521 meshes with the gears 425 of all cleaning components 42 to form a transmission. The power is transmitted step by step to the ring blade holder 422 and the blades 423 in the slot. The blades 423 complete the dust scraping operation on the outer wall of the filter bag 2. The partition 511 separates the air supply chamber 513 that delivers airflow and the drive chamber 512 that transmits power. The airflow flowing in the air supply chamber 513 will not flow into the drive chamber 512 and contact the transmission components of the synchronous rotation mechanism 52. A single set of external gear rings 521 can simultaneously mesh with the gears 425 of multiple sets of cleaning components 42 to output rotational power in a unified manner, thereby synchronously driving all dust removal mechanisms 4 to carry out the cleaning operation of the filter bag 2.

[0054] Reference Figure 10 and Figure 12As shown: The drive assembly 5 also includes a lifting mechanism 53. The connecting box 51 is fixedly connected to the ring frame 41. The lifting mechanism 53 drives the ring frame 41 to move synchronously by driving the connecting box 51 to lift and lower.

[0055] The lifting mechanism 53 includes a lead screw 531, a screw sleeve 532, a second rotary driver 533, and a guide rod 534. The axis of the lead screw 531 is parallel to the annular frame 41. The screw sleeve 532 is threadedly connected to the lead screw 531 and is fixedly connected to the connecting box 51. The second rotary driver 533 is used to drive the lead screw 531 to rotate. The guide rod 534 is arranged parallel to the lead screw 531. The connecting box 51 is slidably connected to the guide rod 534.

[0056] The second rotary actuator 533 outputs power to drive the lead screw 531 to rotate continuously. The threaded sleeve 532 and the lead screw 531 cooperate through a threaded structure to generate axial displacement. The threaded sleeve 532 is fixedly assembled with the connecting box 51 of the drive assembly 5. When the lead screw 531 rotates, the connecting box 51 slides linearly along the guide rod 534 arranged parallel to the lead screw 531. When the connecting box 51 moves, it drives all the dust-sweeping mechanisms 4 to reciprocate up and down along the axial direction of the filter bag 2. The guide rod 534 forms a limiting constraint on the connecting box 51. During the lifting and lowering process, the connecting box 51 will not have lateral displacement. The dust-sweeping mechanism 4 always moves stably against the outer wall of the filter bag 2. The lead screw 531 is provided with an effective threaded section that matches the full length of the filter bag 2, driving the dust-sweeping mechanism 4 to complete the entire axial height of the filter bag 2, thereby completing the full coverage cleaning operation of multiple filter bag 2 axial areas.

[0057] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention.
