Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of dust removal, in particular to a dust removal device for a feed production line. BACKGROUND

[0002] In the process of feed production, various processes such as raw material feeding, crushing, mixing, screening and finished product packaging will inevitably produce a large amount of dust. These dusts are complex in composition, covering raw material dusts such as corn and soybean meal, nutritional ingredient dusts such as vitamins and trace elements, and mixed dusts formed during the processing process. For example, during the raw material crushing stage, the material is broken at high speed, and fine particles will be scattered everywhere with the air; the stirring of different materials in the mixing process will also cause dust to be raised.

[0003] Traditional dust removal devices for feed production lines have many drawbacks. Some devices rely only on simple dust suction fans, which cannot effectively clean dust adhering to the surface of the feed or inside the equipment; some devices use cloth bags for dust removal, which are easily clogged by dust, resulting in frequent cleaning and maintenance, reduced dust removal efficiency, and backflow of dust during cleaning, affecting the production environment and product quality.

[0004] Chinese Patent No. CN221267504U discloses a dust removal device for a feed production line, which includes a dust collector body, an air inlet pipeline and a collection box. The lower end of the dust collector body is fixed with a collection box, the inside of the collection box is provided with a dust baffle, and the inside of the collection box below the dust baffle is movably provided with a balance plate. When the weight of the dust is greater than the weight of the gravity block, the balance plate rotates to the gravity sensor at one end, the dust falls into the dust storage box, and the push plate pushes the dust into the extrusion box. During the process, the spray head sprays water to wet the dust. After the hydraulic push rod and the water pipe joint are working, the extrusion plate starts to press the dust in the extrusion box into a block shape, which is beneficial to the recycling and utilization of the dust, and solves the problem of poor sealing of the collection device and overflow of dust during movement in the process of collecting and processing the existing dust.

[0034] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0035] Example 1, as Figure 3As shown, a dust removal device for a feed production line includes an outer casing 1. A dust hopper 11 is fixedly connected to the lower end of the outer casing 1. An air inlet 12 is fixedly connected to one side of the dust hopper 11. A partition plate 13 is fixedly connected to the inner surface of the outer casing 1. The partition plate 13 consists of two horizontal plates and two vertical plates, with the distance between the two vertical plates being less than the length of the two horizontal plates. A fixed seat 14 is fixedly connected to the inner surface of the partition plate 13 at its middle position. Four air vents 141 are provided on the outer surface of the fixed seat 14. Unremoved air enters the inner cavity of the outer casing 1 through the air inlet 12 and passes through the air vents 141 into the dust removal chamber. A rotating seat 15 is rotatably connected to the inner surface of the fixed seat 14. The outer side of the rotating seat 15 is inclined downwards. The dust shaken off and blown off the dust bags 16 will concentrate between the rotating seat 15 and the fixed seat 14 along the inclined surface of the rotating seat 15. Several dust bags 16 are provided at the upper end of the rotating seat 15. The inner surface of each dust bag 16 is provided with a skeleton 161. The skeleton 161 is made of glass fiber reinforced nylon. A dust removal mechanism 17 is provided at the upper end of the dust bags 16. A tube sheet 18 is fixedly connected to the inner surface of the outer box 1 and above the dust removal mechanism 17. A movable filter assembly 2 is provided in the inner cavity of the outer box 1. The movable filter assembly 2 includes a filter cloth 20. A rebound assembly 3 is provided in the middle position between the partition plate 13 and the fixed seat 14. A cleaning assembly 4 is provided on the right side of the partition plate 13. An air blowing assembly 5 is provided on the left side of the partition plate 13.

[0036] The frame 161 has good elasticity and toughness, which allows the dust bag 16 to undergo partial deformation and quickly return to its original position.

[0037] The outer surface of the outer casing 1 is provided with a maintenance port, which facilitates the cleaning of accumulated dust inside when the machine is stopped.

[0038] Filtration process: Dust-laden gas enters the outer casing 1 through the partition plate 13, rises and enters the dust removal chamber through the vent 141, passes through the dust removal bag 16 suspended on the dust removal mechanism 17, and the dust is blocked and adsorbed on the outer surface of the dust removal bag 16 due to sieving, inertia and interception effects, gradually forming a filter layer called the "dust primary layer", which itself becomes a highly efficient filter medium. The purified gas enters the clean space inside the dust removal bag 16 and finally gathers in the clean air chamber at the top, that is, the space between the upper end of the partition plate 13 and the dust removal mechanism 17, and is finally discharged through the exhaust pipe at the top.

[0039] This invention, through the cooperation of its various components, utilizes the outer casing 1, the movable filter component 2, and the rebound component 3. When the filter cloth 20 dynamically filters the air, it causes the dust bag 16 to twist and rebound, intermittently vibrating and shaking off the dust on its surface. This reduces the cleaning burden and frequency of the subsequent dust removal mechanism 17. Simultaneously, the cleaning component 4 and the air blowing component 5 clean, tap, and blow air onto the filter cloth 20, maintaining the filter cloth 20's air permeability over a long period. This prevents increased airflow resistance due to clogging of the filter cloth 20, achieving a continuous operating state of "uninterrupted filtration and uninterrupted cleaning." This reduces the frequency of manual maintenance, making it suitable for uninterrupted production scenarios in feed production lines and avoiding production line shutdowns caused by dust removal equipment maintenance.

[0040] Example 2 is based on Example 1, and aims to achieve uninterrupted filtration and cleaning.

[0041] like Figure 6 and Figures 6-10 The movable filter assembly 2 also includes a motor 21 fixedly installed on the left side of the inner surface of the outer casing 1. The output end of the motor 21 is fixedly connected to a bevel gear transmission group 22. A rotating roller 23 is fixedly connected to the rear side of the bevel gear transmission group 22. A rotating shaft 24 is fixedly connected to the right side of the bevel gear transmission group 22. A bevel gear transmission group 25 is fixedly connected to the end of the rotating shaft 24 away from the bevel gear transmission group 22. A rotating shaft 26 is fixedly connected to the rear end of the bevel gear transmission group 25. Five separated rotating rollers 261 are fixedly connected to the outer surface of the rotating shaft 26. A rotating roller 27 is driven to the front end of the rotating shaft 26. A rotating roller 28 is driven to the front end of the rotating roller 27. The rotating rollers 23, 261, 27, and 28 are rotatably connected to the surface of the filter cloth 20, thereby driving the filter cloth 20 to move.

[0042] Furthermore, the filter cloth 20 mentioned above is made of PTFE-coated polyester needle-punched felt, which has the lowest surface energy of all solid materials. Water and oil cannot penetrate it, and damp and greasy dust cannot adhere firmly. It can also withstand the continuous tension of the roller and the mechanical friction of the scraper, resulting in a long service life.

[0043] The filter cloth 20 can intercept some corn cobs that are not completely crushed, bean pod fragments, and feed clumps that have clumped due to moisture, preventing heavy or hard lumps from accelerating the wear of the dust collection bag 16. In addition, these lumps are too large to be effectively removed by dust cleaning and will easily clog the dust collection bag 16.

[0044] Then, the starter motor 21 drives the bevel gear transmission group 1 22, the rotating shaft 1 24 and the bevel gear transmission group 25 to rotate. Through two belt transmission mechanisms, the rotating roller 1 23, the rotating roller 261, the rotating roller 3 27 and the rotating roller 4 28 rotate synchronously, so that the filter cloth 20 always keeps moving.

[0045] A silicone lip-shaped sealing strip is installed at the position where the filter cloth 20 passes through the partition plate 13. One strip is installed on each of the upper and lower sides of the gap in the partition plate 13, so that the "lip" of the sealing strip presses against the surface of the filter cloth 20. When the filter cloth 20 moves, the lip can follow and adhere to the filter cloth 20, which not only blocks the external air, but also does not jam the filter cloth 20. A thin layer of felt or high-density sponge pad is then attached to the outside of the lip-shaped sealing strip. This is commonly used in industrial equipment dust prevention. It first blocks the dust around the gap, preventing dust from entering the sealing surface and damaging the lip-shaped strip, and at the same time, it helps to enhance the seal and prevent external air from leaking in from the edge of the gap. All of the above belong to the conventional technical field in the prior art.

[0046] like Figure 6 The rebound assembly 3 includes a worm gear transmission group 31 fixedly connected to the outer surface of the rotating shaft 24. A single-tooth gear 32 is fixedly connected to the upper end of the worm gear transmission group 31. A gear 33 is meshed with the outer surface of the single-tooth gear 32. Each full rotation of the single-tooth gear 32 can drive the gear 33 to rotate by the central angle of one tooth, thereby driving the upper rotating seat 15 and the dust bag 16 to rotate together.

[0047] The worm gear transmission assembly 31 consists of a meshing worm wheel and a worm, and belongs to the conventional technical field in the prior art.

[0048] When the motor 21 drives the bevel gear transmission assembly 22 to rotate, it will synchronously drive the worm gear transmission assembly 31 and the single-tooth gear 32 to rotate, so that the single-tooth gear 32 meshes with the gear 33. Each rotation of the single-tooth gear 32 can drive the gear 33 to rotate one tooth position around its own axis, thereby driving the rotating seat 15 and the dust collection bag 16 to rotate synchronously.

[0049] A connecting frame 34 is fixedly connected to the inner surface of gear 33. A fixing plate 35 is fixedly connected to the rear side of the inner surface of outer housing 1. A fixing disc 36 is fixedly connected to the upper end of fixing plate 35. A guide groove 361 is provided at the upper end of fixing disc 36. A groove 362 is provided at the upper end of fixing disc 36. A rotating rod 37 is rotatably connected to the bottom inner wall of groove 362. A torsion spring 371 is fixedly connected to the outer surface of rotating rod 37. The end of torsion spring 371 away from rotating rod 37 is fixedly connected to the inner surface of groove 362.

[0050] The guide groove 361 mentioned above is composed of a circular groove and three V-shaped grooves connected together;

[0051] A one-way turntable 38 is fixedly connected to the lower end of the connecting frame 34. A ratchet 381 is rotatably connected to the inner surface of the one-way turntable 38. A locking block 382 is rotatably connected to the inner surface of the one-way turntable 38. The lower end of the ratchet 381 is fixedly connected to the outer surface of the rotating rod 37. A guide rod 383 is fixedly connected to the lower end of the locking block 382. The outer surface of the guide rod 383 is slidably connected to the inner surface of the guide groove 361. When the guide rod 383 moves to the protruding position of the guide groove 361, it will drive the locking block 382 to rotate, thereby causing the ratchet 381 to lose its limit. Under the elastic force of the torsion spring 371, the rotating rod 37 and the ratchet 381 will be reset to the initial position.

[0052] The angle difference between the three V-shaped grooves is 120 degrees, meaning that the dust bag 16 will rebound once every time it rotates 120 degrees.

[0053] Furthermore, when gear 33 and connecting frame 34 are driven to rotate clockwise by single-tooth gear 32, connecting frame 34 simultaneously drives one-way turntable 38, locking block 382 and guide rod 383 to rotate clockwise. In this state, locking block 382 and ratchet 381 abut against each other, locking block 382 drives ratchet 381 to rotate at the same time, ratchet 381 simultaneously drives rotating rod 37, torsion spring 371 and connecting rod 372 to rotate, connecting rod 372 drives rotating seat 15 to rotate as a whole, so that the dust bag 16 rotates together with one tooth angle;

[0054] Synchronously, as the rotating rod 37 rotates, it pulls the torsion spring 371 to store energy. Under the repeated meshing of the single-tooth gear 32 and gear 33, the gear 33 drives the rotating seat 15 and the dust bag 16 to rotate at increasingly larger angles. When the rotation angle is equal to 120 degrees, the guide rod 383 also moves to the V-shaped groove on the guide groove 361 and drives the locking block 382 to move to one side along the trajectory of the V-shaped groove. This further causes the ratchet 381 to lose its limit. Under the drive of the torsion spring 371, the ratchet 381 will quickly rotate in the opposite direction to reset, thereby synchronously driving the rotating seat 15 and the dust bag 16 to rebound. The surface dust is shaken off by inertial vibration, reducing the cleaning burden of the subsequent dust cleaning mechanism 17. It is no longer necessary to consume a lot of airflow to impact the thick dust layer. Only the residual fine dust needs to be cleaned. This can reduce the air source consumption of the dust cleaning mechanism 17 and avoid the problem of air not being able to "blow through" and incomplete cleaning due to the dust layer being too thick.

[0055] The existing timed air blowing system cleaning mechanism 17 can periodically blow air to clean the dust collection bag 16. It exerts force from inside the dust collection bag 16 to blow off the attached fine dust, complementing the dust shaking. Timed air blowing can replenish the cleaning in time, further avoiding the clogging of the pores of the dust collection bag 16 and maintaining its fine filtration capacity. It is especially suitable for scenarios with fluctuating dust concentration in feed production, ensuring the long-term stable operation of the dust collection bag 16.

[0056] The dust removal process of the aforementioned dust removal mechanism 17 is as follows: When the dust layer on the dust collector bag 16 thickens and the operating resistance reaches a set value, the dust removal system is activated. The pulse valve opens in a very short time (approximately 0.1 seconds), injecting high-pressure compressed air into the venturi tube inside the dust collector bag 16, inducing several times the amount of secondary airflow, forming a brief and powerful reverse airflow. This airflow causes the dust collector bag 16 to expand and shake violently, generating strong acceleration, thereby breaking and shaking off the dust layer on the outer surface, which falls into the ash hopper 11 below. This is a conventional technical field in the prior art.

[0057] The upper end of the rotating rod 37 extends to the upper end of the one-way turntable 38 and is fixedly connected to the connecting rod 372. The upper end of the connecting rod 372 is fixedly connected to the lower end of the rotating seat 15.

[0058] like Figure 11 and Figure 12 The cleaning component 4 includes a cleaning brush 40 that can clean the surface of the filter cloth 20. The cleaning brush 40 is located on the lower left side of the partition plate 13 and is rotatably connected to the inner surface of the outer casing 1. Baffles 41 are fixedly connected to the gap between the rotating shaft 26 and the five rotating rollers 261. A support rod 42 is rotatably connected to the left side of the partition plate 13 and located on the inner surface of the outer casing 1. Swing frames 43 that are adapted to the position of the baffles 41 are fixedly connected to the upper and lower sides of the support rod 42. A knocking block 44 is fixedly connected to the end of several swing frames 43 away from the support rod 42. A knocking block 44 is fixedly connected to the upper left end of several swing frames 43. The left ends of several knocking blocks 44 are fixedly connected to the right side of the partition plate 13. When the rotating shaft 26 rotates, the baffles 41 will intermittently move the swing frames 43 and knocking blocks 44 to knock on the surface of the filter cloth 20. A spring 45 is fixedly connected to the left side of the upper swing frame 43.

[0059] The outer surfaces of the two striking blocks 44 mentioned above are provided with rubber to shake off the dirt on the surface of the filter cloth 20 with a flexible impact force, so as to avoid damaging the filter cloth 20.

[0060] The cleaning brush 40 can remove floating dust from the surface of the filter cloth 20, preventing the dust from clumping together.

[0061] Furthermore, when the rotating shaft 26 rotates, it will synchronously drive the baffle 41 to intermittently push the lower striking block 44 closer to the partition plate 13, causing the upper striking block 44 to swing in the opposite direction to strike the filter cloth 20. When the baffle 41 passes the lower striking block 44, the lower striking block 44 loses its obstruction, and the spring 45 will pull the striking block 44 back, causing the lower striking block 44 to strike the filter cloth 20. The two alternately strike the filter cloth 20, shaking off the sticky dust at the pore inlet of the filter cloth 20 and preventing the channel from being blocked.

[0062] like ​The air blowing assembly 5 includes a reciprocating rod 52, which is located on the left side of the partition plate 13 and is rotatably connected to the inner surface of the outer housing 1. Sliding plates 53 are slidably connected to both sides of the outer surface of the reciprocating rod 52, and a fixing plate 54 is fixedly connected to the inner surface of the outer housing 1 and located on the left side of the partition plate 13.

[0063] Airbags 55 are provided on both the front and rear sides of the upper end of the fixed plate 2 54. The sides of the two sliding plates 53 that are far apart from each other are fixedly connected to the airbags 55 on the same side. The left side of the two airbags 55 is fixedly connected to the air nozzles 56. The lower end of the air nozzles 56 is fixedly connected to the fixed plate 2 54. The initial directions of the two sliding plates 53 are the same.

[0064] The connection between the reciprocating rod 52 and the sliding plate 53 mentioned above is a ball screw mechanism in the prior art. When the reciprocating rod 52 rotates in one direction, it will drive the reciprocating rod 52 to keep reciprocating on its surface.

[0065] Furthermore, each of the two airbags 55 mentioned above is provided with two one-way valves on its surface. One valve is connected to the jet port 56 and can only release air, not allow air to enter. The other valve is connected to the external space and can only replenish air to the airbag 55, not release air.

[0066] The two sliding plates 53 mentioned above always run in the same direction. When the reciprocating rod 52 rotates, it drives the front sliding plate 53 to move forward and squeeze the airbag 55, so that the gas in the airbag 55 is transmitted to the jet nozzle 56 and sprayed out to blow air onto the filter cloth 20. Simultaneously, the rear sliding plate 53 pulls the rear airbag 55 to reset and expand, allowing external air to enter. When the front airbag 55 is squeezed and begins to reset, the rear airbag 55 begins to be squeezed and blown out. The two are seamlessly connected, ensuring that the moving filter cloth 20 is always blown out, thereby removing fine dust from the gaps between the fibers of the filter cloth 20. This can keep the filter cloth 20 breathable for a long time and avoid increased airflow resistance due to clogging of the filter cloth 20.

[0067] It should be noted that the transmission connections used in this invention are all made through belt drive mechanisms, which belong to the conventional technical field in the prior art.

[0068] Therefore, this solution, through the cooperation of the outer casing 1, the moving filter assembly 2, and the rebound assembly 3, drives the dust collection bag 16 to rotate intermittently and slowly while the filter cloth 20 continuously moves and filters. After reaching a certain angle, it rebounds, shaking off the dust adsorbed on the outer surface of the dust collection bag 16. This reduces the cleaning burden on the subsequent dust removal mechanism 17 and avoids the problem of incomplete cleaning due to excessive dust layer on the dust collection bag 16. Furthermore, the cleaning assembly 4 and the air blowing assembly 5 simultaneously sweep, tap, and blow air on the moving filter cloth 20 to achieve comprehensive cleaning from the surface to the depth. The filter cloth 20 can be maintained without stopping the machine, avoiding the production line interruption caused by the shutdown and replacement of the traditional fixed filter cloth due to blockage. This solution is suitable for the continuous pelleting and mixing production rhythm of feed mills.

[0069] It should be noted that the specific installation method of the motor 21, the circuit connection method, and the control method used in this invention are all conventional designs, and will not be described in detail here.

[0070] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of this invention is defined by the appended claims and their equivalents.
