Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of dust collectors, in particular to a bag-type dust collector based on the recycling and crushing process of artificial boards. BACKGROUND

[0002] In the recycling and crushing process of artificial boards, a large amount of dust will be generated. If not effectively treated, it will not only pollute the production environment, but also endanger the health of the operators. As a special equipment for environmental protection, the bag-type dust collector has many problems when used in this scene. Because the dust of artificial boards has viscosity, it is easy to adhere to the filter bag, reducing the air permeability and dust removal efficiency. The sharp particles generated by crushing will wear the filter bag, shortening its service life. In addition, the airflow distribution is uneven, and some filter bags are heavily loaded. The existing solutions have limitations, such as high energy consumption by increasing the frequency of dust removal and high cost of using wear-resistant materials. Therefore, it is necessary to develop a new type of bag-type dust collector that is suitable for use.

[0003] In the patent with the patent number CN220405096U, a pulse bag-type dust collector for plate processing and production is disclosed, which includes a box body, a clamping plate installed in the box body, a filter bag provided on the clamping plate, a blowing part provided on the upper part of the filter bag, a vibration part provided on the clamping plate, and an open setting at the bottom end of the box body. The bottom end of the box body is fixedly connected with a connecting ring. The patent sets an arc piece, a motor, a cam, a sleeve, a fixed rod, and a shaking spring, replaces the traditional dust hopper with a bag-type dust hopper, and controls the rotation of the cam through the motor when unloading dust, so that the cam repeatedly knocks the arc piece, and the clamping plate moves left and right under the action of the sleeve, the fixed rod, and the shaking spring, so that the clamping plate drives the bag-type dust hopper to move left and right, achieving the effect of auxiliary dust removal, so that the dust accumulated at the bottom of the box body is quickly discharged from the interface. The setting of the arc piece, the motor, the cam, the sleeve, the fixed rod, and the shaking spring drives the bag-type dust hopper to shake, thereby accelerating the unloading of dust.

[0004] The existing technology has the following defects: It is difficult to effectively avoid the wear of the filter bag caused by the sharp particles generated by crushing: the dust generated by the crushing of artificial boards contains sharp particles, which will continuously erode the surface of the filter bag under the action of the airflow, causing the filter bag to wear. If the wear of the filter bag caused by the sharp particles cannot be effectively avoided, scratches and holes will appear on the surface of the filter bag soon, and the damage range will expand with the increase of the use time, thereby causing the dust removal effect to deteriorate, a large amount of dust to escape from the damaged part, and the dust content of the discharged gas to exceed the standard. It will also shorten the service life of the filter bag, and frequent replacement of the filter bag will increase the operating cost and maintenance workload of the equipment, thereby affecting the continuity of production and reducing the overall production efficiency.

[0005] Filter bag clogging leads to poor dust removal efficiency: During the recycling and crushing of engineered wood products, the dust particles generated vary in size. Some fine, sticky dust particles adhere to the surface of the filter bags, reducing their air permeability and causing clogging. Traditional dust removal methods, such as pulse jet cleaning, cannot completely remove dust deep within the filter bags and in the crevices. As operating time increases, the clogging becomes more severe, resulting in reduced dust removal efficiency, excessive dust content in exhaust gases, and environmental pollution. Frequent filter bag replacement increases costs and workload, and downtime for maintenance disrupts production continuity, reducing overall production efficiency. Summary of the Invention

[0006] Given that existing technologies cannot effectively prevent the wear of filter bags by sharp particles generated during crushing and the poor dust removal effect caused by filter bag clogging, a bag filter dust collector based on the process of recycling and crushing artificial boards is proposed.

[0007] This application provides a baghouse dust collector based on the process of recycling and crushing engineered wood panels. Its purpose is to: through the design of a flow guiding mechanism and a filter bag mechanism, the flow guiding mechanism ensures uniform distribution of dust-laden airflow, preventing excessive load on localized filter bags. It also provides initial buffering and dispersion of sharp particles in the airflow, reducing direct scouring of the filter bags by sharp particles, effectively reducing filter bag wear, and extending filter bag lifespan. The filter bag mechanism enhances the interception of fine, sticky dust, making it easier for fine, sticky dust to detach, improving filter bag permeability, and preventing clogging. This improves dust removal efficiency, reduces the dust content in the exhaust gas, reduces operating costs and maintenance workload, and ensures production continuity and efficiency.

[0008] The technical solution of the present invention is as follows: a bag filter based on the process of recycling and crushing artificial board, including a base frame, a shell assembly fixedly installed on the top of the base frame, and a dust removal assembly set on the top of the shell assembly, and also including a flow guiding mechanism for guiding the airflow direction, a filter bag mechanism with dual filtration function, and a drive mechanism for adjusting the flow guiding mechanism and the filter bag mechanism. The flow guiding mechanism includes a flow guiding pipe fixedly installed on the inner wall of the housing assembly. Two air guide ports are symmetrically opened on the outer wall of the flow guiding pipe. Hinges are fixedly connected to the inner walls of the two air guide ports. An arc-shaped window is rotatably connected to the outer wall of the hinge. The two arc-shaped windows open in opposite directions. Multiple equidistant particle baffles are fixedly connected to the inner wall of the flow guiding pipe. Multiple through holes are opened on the inner wall of the flow guiding pipe. The multiple through holes are respectively located below the corresponding particle baffles. A dust collection component is provided at the bottom of the flow guiding pipe.

[0009] By adopting the above scheme, the flow guiding mechanism can reasonably guide the dust-laden airflow, making the airflow evenly distributed inside the dust collector, improving the filtration efficiency of the filter bag mechanism, reducing filtration dead angles, and thus improving the overall dust removal effect of the dust collector, so that the emitted gas meets environmental protection standards. At the same time, the particle baffle can effectively intercept large particulate impurities in the dust-laden airflow, preventing these large particulate impurities from directly entering the filter bag mechanism, thereby reducing the filtration burden on the filter bags and extending their service life.

[0010] Furthermore, the dust collection assembly includes a fixing block fixedly connected to the bottom of the guide tube, and a hole plate slidably connected to the bottom of the guide tube. A pull rod is fixedly connected to the outer wall of the hole plate, and the pull rod is slidably connected to the fixing block. The pull rod passes through the housing assembly and extends to the outside.

[0011] Using the above scheme, by pulling the lever, the holes on the orifice plate can be aligned with the through holes at the bottom of the guide pipe. When they are aligned, large particles of impurities will fall into the dust collection funnel below under the action of gravity, passing through the through holes and the holes on the orifice plate. If there are many large particles of impurities in the dust-laden airflow, the lever displacement can be electrically controlled to increase the cleaning frequency, so as to ensure the smooth flow of the guide pipe and maintain the efficient operation of the entire dust collection system.

[0012] Furthermore, the drive mechanism includes a rotary cylinder fixedly mounted on the outer wall of the base frame, and a displacement component and a rotation component slidably connected to the outer wall of the housing assembly.

[0013] Furthermore, the rotating assembly includes a rotating rod sleeved on the output end of the rotating cylinder. The rotating rod is fixedly connected to two arc-shaped windows with steel wire ropes. Two limiting grooves are opened on the inner wall of the rotating rod, and the two steel wire ropes are respectively wound in the corresponding limiting grooves.

[0014] Furthermore, the outer wall of the rotating rod is provided with a threaded groove, and the displacement assembly includes a displacement frame that is threadedly connected to the threaded groove. The outer wall of the displacement frame is fixedly connected with a plurality of equally spaced racks.

[0015] By adopting the above solution, the rotating cylinder drives the rotating rod through the set drive mechanism. With the help of the steel wire rope and the limiting groove, the opening and closing of the arc-shaped window can be precisely controlled, and the direction of the dust-laden airflow can be changed as needed to optimize the airflow distribution and improve the filtration efficiency. The threaded groove of the rotating rod cooperates with the displacement frame to convert the rotation into linear motion. The rack on the displacement frame drives the filter bag mechanism to turn, so that all parts of the filter bag can filter evenly and extend its service life. The whole system realizes the coordination of airflow guidance and filter bag mechanism, reduces equipment complexity and energy consumption, and improves work efficiency and automation.

[0016] Furthermore, the filter bag mechanism includes multiple filter bag holders fixedly installed on the inner wall of the housing assembly, with inner filter bags fixedly installed on the outer wall of the filter bag holders, and an outer cover assembly provided on the outside of the inner filter bags.

[0017] Furthermore, the outer cover assembly includes an outer filter bag rotatably connected to the inner wall of the housing assembly. The top of the outer filter bag is provided with a toothed groove, and the outer wall of the outer filter bag is provided with an air passage groove, which is located only on one side of the outer filter bag.

[0018] Furthermore, the outer cover assembly also includes a plurality of cleaning brushes fixedly connected to the inner wall of the housing assembly. The cleaning brushes are located on the outside of the outer filter bag and are used to clean the outside of the outer filter bag.

[0019] By adopting the above scheme, the inner filter bag filters fine dust through the filter bag mechanism, while the outer filter bag can rotate. The air passage makes the airflow distribution more reasonable, avoiding excessive load on local filter bags. The dust removal brush cleans the surface dust when the outer filter bag rotates, maintaining the air permeability of the filter bag, extending its service life, and improving the overall filtration efficiency and stability, ensuring the continuous and efficient operation of the equipment.

[0020] Furthermore, the housing assembly includes a dust collection box fixedly installed on the top of the base frame, a dust collection funnel fixedly connected to the bottom of the dust collection box, an air inlet pipe connected to the outer wall of the dust collection funnel, a dust discharge valve installed at the bottom of the dust collection funnel, a clean air box fixedly connected to the top of the dust collection box, and an exhaust pipe connected to the outer wall of the clean air box.

[0021] Furthermore, the dust removal assembly includes a gas compression tank fixedly installed on the outer wall of the dust collection box. Multiple pulse tubes are fixedly connected to the outer wall of the gas compression tank, and multiple blow nozzles are fixedly connected to the outer wall of the pulse tubes. Both the pulse tubes and the blow nozzles are located inside the clean air box.

[0022] Using the above scheme, dust-laden gas enters through the inlet pipe via the housing assembly and the dust removal assembly, is filtered in the dust collector, and the filtered dust falls to the bottom of the funnel under gravity and is discharged through the dust discharge valve; the filtered clean gas rises to the clean air box and is discharged from the exhaust pipe; the gas compression tank of the dust removal assembly stores high-pressure gas, and the pulse pipe and blower head can perform pulse jet cleaning of the filter bags at regular intervals, causing the dust attached to the filter bags to fall off, ensuring the air permeability and filtration efficiency of the filter bags, ensuring stable operation of the equipment, and improving the overall dust removal effect.

[0023] The beneficial effects of this invention are: The flow guiding mechanism effectively guides the dust-laden airflow and intercepts large particles of impurities. The flow guiding pipe ensures even distribution of airflow within the dust collector, preventing excessive load on local filter bags, improving the filtration efficiency of the filter bag mechanism, and reducing filtration dead zones. The particle baffle intercepts large particles of impurities in the dust-laden airflow, reducing the filtration burden on the filter bags. Overall, this achieves the effects of improving dust removal efficiency, ensuring that exhaust gases meet standards, extending the service life of filter bags, and maintaining the efficient operation of the dust removal system.

[0024] The filter bag mechanism and dust removal components provide dual filtration, dust removal, and pulse cleaning. The inner filter bag filters fine dust, while the outer filter bag can rotate. The air ducts ensure a more reasonable airflow distribution, preventing excessive load on local filter bags. The dust removal brush cleans surface dust as the outer filter bag rotates, maintaining its air permeability. Overall, this improves filtration efficiency and stability, ensuring continuous and efficient operation of the equipment and guaranteeing filter bag air permeability and filtration efficiency.

[0025] The specially designed drive mechanism precisely controls the arc-shaped window and steers the filter bag mechanism. A rotary cylinder drives a rotating rod, with a wire rope and a limit groove working together to precisely control the opening and closing of the arc-shaped window, changing the direction of the dust-laden airflow as needed and optimizing airflow distribution. The threaded groove of the rotating rod, in conjunction with the displacement frame, converts rotation into linear motion. The rack on the displacement frame drives the filter bag mechanism to rotate, ensuring uniform filtration across all parts of the filter bag. The overall design achieves coordinated flow guidance and filter bag mechanism operation, reducing equipment complexity and energy consumption, improving work efficiency and automation, and extending the filter bag's service life.

[0028] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0029] Reference Figure 1 - Figure 13 A bag filter dust collector based on the process of recycling and crushing artificial boards is provided, including a base frame 1, a shell assembly 2 fixedly installed on the top of the base frame 1, and a dust removal assembly 4 disposed on the top of the shell assembly 2. It also includes a flow guiding mechanism 5 for guiding the airflow direction, a filter bag mechanism 6 with dual filtration function, and a drive mechanism 3 for adjusting the flow guiding mechanism 5 and the filter bag mechanism 6.

[0030] Reference Figure 4 - Figure 7 The flow guiding mechanism 5 includes a flow guiding pipe 51 fixedly installed on the inner wall of the housing assembly 2. Two air guide ports 52 are symmetrically opened on the outer wall of the flow guiding pipe 51. A hinge 53 is fixedly connected to the inner wall of each of the two air guide ports 52. An arc-shaped window 54 is rotatably connected to the outer wall of the hinge 53. The two arc-shaped windows 54 open in opposite directions. A plurality of equidistant particle baffles 57 are fixedly connected to the inner wall of the flow guiding pipe 51. A plurality of through holes 56 are opened on the inner wall of the flow guiding pipe 51. The plurality of through holes 56 are respectively located below the corresponding particle baffles 57. A dust collection assembly 55 is provided at the bottom of the flow guiding pipe 51.

[0031] Specifically, the two arc-shaped windows 54 open in opposite directions. Depending on the actual dust removal needs and airflow conditions, one of the air vents 52 can be selectively opened to change the direction of the dust-laden airflow. When the dust-laden airflow enters the guide pipe 51, large particles of impurities will collide with the particle baffle 57 under the action of inertia and gravity, thus being blocked and retained at the bottom of the guide pipe 51.

[0032] The flow guiding mechanism 5 can guide the dust-laden airflow in a reasonable way, so that the airflow is evenly distributed inside the dust collector, improving the filtration efficiency of the filter bag mechanism 6, reducing filtration dead angles, thereby improving the dust removal effect of the entire dust collector and making the emitted gas meet environmental protection standards. At the same time, the particle baffle 57 can effectively intercept large particles of impurities in the dust-laden airflow, preventing these large particles of impurities from directly entering the filter bag mechanism 6, thereby reducing the filtration burden on the filter bags and extending the service life of the filter bags.

[0033] Reference Figure 6 - Figure 7 The dust collection assembly 55 includes a fixing block 551 fixedly connected to the bottom of the guide pipe 51, and a hole plate 552 slidably connected to the bottom of the guide pipe 51. A pull rod 553 is fixedly connected to the outer wall of the hole plate 552. The pull rod 553 is slidably connected to the fixing block 551. The pull rod 553 passes through the housing assembly 2 and extends to the outside.

[0034] By pulling the lever 553, the holes on the orifice plate 552 can be aligned with the through hole 56 at the bottom of the guide pipe 51. When the two are aligned, large particles of impurities will fall into the dust collection funnel 22 below under the action of gravity, passing through the through hole 56 and the holes on the orifice plate 552. If there are many large particles of impurities in the dust-laden airflow, the lever 553 can be moved electrically to increase the cleaning frequency, so as to ensure the smooth flow of the guide pipe 51 and maintain the efficient operation of the entire dust collection system.

[0035] Reference Figure 3 - Figure 12 The drive mechanism 3 includes a rotary cylinder 31 fixedly installed on the outer wall of the base frame 1, and a displacement assembly 32 and a rotation assembly 33 slidably connected to the outer wall of the housing assembly 2. The rotation assembly 33 includes a rotating rod 331 sleeved on the output end of the rotary cylinder 31. Steel wire ropes 334 are fixedly connected between the rotating rod 331 and the two arc-shaped windows 54. Two limiting grooves 333 are opened on the inner wall of the rotating rod 331, and the two steel wire ropes 334 are respectively wound in the corresponding limiting grooves 333. A threaded groove 332 is opened on the outer wall of the rotating rod 331. The displacement assembly 32 includes a displacement frame 321 threadedly connected to the threaded groove 332. Multiple equidistant racks 322 are fixedly connected to the outer wall of the displacement frame 321.

[0036] Specifically, the function of the limiting groove 333 is to constrain the wire rope 334 to prevent it from shifting or tangling during rotation, ensuring that the wire rope 334 can stably drive the arc window 54 to open or close; the displacement frame 321 will slide linearly along the outer wall of the housing assembly 2, and the rack 322 on the displacement frame 321 can cooperate with the filter bag mechanism 6 to realize the steering adjustment of the filter bag mechanism 6.

[0037] Through the drive mechanism 3, the rotary cylinder 31 drives the rotating rod 331. With the help of the wire rope 334 and the limiting groove 333, the opening and closing of the arc-shaped window 54 can be precisely controlled, and the direction of the dust-laden airflow can be changed as needed to optimize the airflow distribution and improve the filtration efficiency. The threaded groove 332 of the rotating rod 331 cooperates with the displacement frame 321 to convert the rotation into linear motion. The rack 322 on the displacement frame 321 drives the filter bag mechanism 6 to rotate, so that all parts of the filter bag can filter evenly and extend its service life. The whole system realizes the coordination of airflow guidance and filter bag mechanism 6, reduces equipment complexity and energy consumption, and improves work efficiency and automation.

[0038] Reference Figure 9 - Figure 13 The filter bag mechanism 6 includes multiple filter bag holders 61 fixedly installed on the inner wall of the housing assembly 2. Inner filter bags 62 are fixedly installed on the outer wall of the filter bag holders 61. An outer cover assembly 63 is provided on the outside of the inner filter bags 62. The outer cover assembly 63 includes an outer filter bag 631 rotatably connected to the inner wall of the housing assembly 2. The top of the outer filter bag 631 is provided with a toothed groove 632. The outer wall of the outer filter bag 631 is provided with an air passage groove 633, which is located only on one side of the outer filter bag 631. The outer cover assembly 63 also includes multiple cleaning brushes 64 fixedly connected to the inner wall of the housing assembly 2. The cleaning brushes 64 are located on the outside of the outer filter bags 631 and are used to clean the outside of the outer filter bags 631.

[0039] Specifically, the filter bag holder 61 provides stable and reliable support for the filter bag, ensuring that the filter bag will not deform or shift during operation; the inner filter bag 62 can effectively filter fine dust particles in the dust-laden airflow; the air passage 633 is located only on one side of the outer filter bag 631, so that the dust-laden airflow can only enter the outer filter bag 631 from a specific side, thereby optimizing the airflow distribution; the cleaning brush 64 is located on the outside of the outer filter bag 631. When the outer filter bag 631 rotates, the cleaning brush 64 can clean the outside of the outer filter bag 631 in time, preventing dust from accumulating on the surface of the filter bag.

[0040] With the filter bag mechanism 6 in place, the inner filter bag 62 filters fine dust, the outer filter bag 631 can rotate, and the air passage 633 makes the airflow distribution more reasonable, avoiding excessive load on local filter bags. The dust removal brush 64 cleans the surface dust when the outer filter bag 631 rotates, maintains the air permeability of the filter bag, extends its service life, and improves the overall filtration efficiency and stability, ensuring the continuous and efficient operation of the equipment.

[0041] Reference Figure 1 - Figure 8 The housing assembly 2 includes a dust collection box 21 fixedly installed on the top of the base frame 1. A dust collection funnel 22 is fixedly connected to the bottom of the dust collection box 21. An air inlet pipe 26 is connected to the outer wall of the dust collection funnel 22. A dust discharge valve 23 is installed at the bottom of the dust collection funnel 22. A clean air box 24 is fixedly connected to the top of the dust collection box 21. An exhaust pipe 25 is connected to the outer wall of the clean air box 24. The dust removal assembly 4 includes a gas compression tank 41 fixedly installed on the outer wall of the dust collection box 21. Multiple pulse pipes 42 are fixedly connected to the outer wall of the gas compression tank 41. Multiple blow nozzles 43 are fixedly connected to the outer wall of the pulse pipes 42. The pulse pipes 42 and the blow nozzles 43 are all located inside the clean air box 24.

[0042] Through the housing assembly 2 and the dust removal assembly 4, dust-laden gas enters through the inlet pipe 26 and is filtered in the dust collector 21. The filtered dust falls to the bottom of the funnel under gravity and is discharged through the dust discharge valve 23. The filtered clean gas rises to the clean air box 24 and is discharged from the exhaust pipe 25. The gas compression tank 41 of the dust removal assembly 4 stores high-pressure gas. The pulse pipe 42 and the blower head 43 can perform pulse blow cleaning on the filter bags at regular intervals, so that the dust attached to the filter bags falls off, ensuring the air permeability and filtration efficiency of the filter bags, ensuring the stable operation of the equipment, and improving the overall dust removal effect.

[0043] Working principle of the invention: During operation, the dust-laden airflow generated by the recycling and crushing of artificial boards enters the guide pipe 51 through the air inlet 26. Initially, the arc-shaped window 54 on the right side of the guide pipe 51 is open, and the arc-shaped window 54 on the left side is closed. Large particles of impurities in the dust-laden airflow are blocked by the particle baffle 57 in the guide pipe 51 and remain at the bottom of the guide pipe 51. The remaining dust-laden airflow enters the dust collection box 21 through the air inlet 52 on the right side.

[0044] At this time, the outer filter bag 631 has an air passage 633 on one side facing left and a sealing surface facing right; the dust-laden airflow is blown from the air guide 52 on the right side to the right side of the outer filter bag 631. The sharp particles in the dust-laden airflow are blocked by the sealing surface of the outer filter bag 631 and fall into the dust collection funnel 22 under the action of gravity; then the dust-laden airflow with the sharp particles removed comes back after contacting the inner wall of the dust collection box 21, and enters the space between the outer filter bag 631 and the inner filter bag 62 from the left side of the outer filter bag 631. Under the filtration of the inner filter bag 62, the clean air enters the clean air box 24 and is discharged from the exhaust pipe 25.

[0045] To prevent blockage caused by prolonged filtration of gas on one side of the inner filter bag 62, the rotary cylinder 31 is activated. The output end of the rotary cylinder 31 drives the rotating rod 331 to rotate. The rotating rod 331 winds and unwinds two steel wire ropes 334 in the two limiting grooves 333 respectively. The right steel wire rope 334 unwinds the right arc-shaped window 54, causing the right arc-shaped window 54 to be repositioned onto the guide tube 51 under the rotation of the hinge 53. Meanwhile, the left steel wire rope 334 pulls the left arc-shaped window 54 to open, thereby changing the dust-laden airflow to enter the dust collector 21 from the left air guide 52.

[0046] As the rotating rod 331 rotates, the threaded groove 332 drives the displacement frame 321 to move. The rack 322 on the displacement frame 321 engages with the toothed groove 632 on the outer filter bag 631, causing the outer filter bag 631 to turn. This causes the side of the outer filter bag 631 with the air passage 633 to turn to the right and the sealing surface to turn to the left, so that the gas is filtered from the other side of the inner filter bag 62. When the outer filter bag 631 turns, it is also cleaned by the cleaning brush 64 fixed inside the dust collector 21.

[0047] During the filtration process, the gas compression tank 41 is activated in stages. The compressed gas generated by the gas compression tank 41 is used to perform pulse cleaning of the inside of the inner filter bag 62 through the pulse pipe 42 and the blow nozzle 43. At the same time, the pull rod 553 is pulled in stages to align the holes on the perforated plate 552 with the through holes 56 at the bottom of the guide pipe 51, allowing large particles of impurities to fall into the dust collection funnel 22. If there are many large particles of impurities in the dust-laden airflow, the pull rod 553 can be moved electrically to increase the cleaning frequency. Finally, the dust discharge valve 23 is opened to clean the dust in the dust collection funnel 22.
