Description

Technical Field

[0001] This invention relates to the field of dust adsorption and filtration technology, specifically to a dust adsorption and filtration device and method for furniture board processing. Background Technology

[0002] Boards are flat, rectangular building material boards made to standard sizes and used in the construction industry. They are used to make components for walls, ceilings, or floors. They also often refer to metal sheets that are forged, rolled, or cast. They are classified as thin boards, medium boards, thick boards, and extra-thick boards. They are usually made to standard sizes and are flat, rectangular building material boards. When processing some wood-based boards, a large amount of dust and debris is generated. In order to prevent the dust from affecting the working environment, the dust needs to be adsorbed and filtered.

[0003] Generally, dust-laden air is drawn into the dust collector by an air pump, and then filtered through filter cartridges to remove the dust. After filtration, a pulse jet dust collector separates the dust adhering to the filter cartridge surface. However, because the filter cartridges near the air inlet come into contact with the dust-laden air first, a certain amount of dust accumulates on their surface after prolonged use, leading to a decrease in filtration efficiency. When the pulse jet dust collector cleans the filter cartridges, since the cartridges are always inside the filtration chamber, the dust-laden air entering the filtration chamber blows away the dust that has separated from the filter cartridges. This causes the dust to re-adhere to other filter cartridges, affecting not only the cleaning effect of the filter cartridge surface but also the filtration effect of subsequent filter cartridges. Summary of the Invention

[0013] As a further embodiment of the present invention: the rectangular guide rod is located below the pulse dust collector, and the hopper and the filter cartridge located above the hopper are coaxial.

[0014] This invention also discloses a method for adsorbing and filtering dust from furniture board processing, which uses the aforementioned dust adsorption and filtration device for furniture board processing and includes the following steps:

[0015] S1: When dust enters the filter chamber through the air inlet pipe, the air containing dust is filtered by the filter cartridge, causing the dust to adhere to the outer wall of the filter cartridge. At the same time, the filtered air enters the exhaust chamber through the filter cartridge and the installation sleeve, and is finally discharged through the exhaust pipe.

[0016] S2: Activate the reversing rotating component. The operation of the reversing rotating component changes the position of the filter cartridge, and at the same time, the dust entering the filter chamber is quickly dispersed to prevent dust from accumulating on a filter cartridge.

[0017] S3: During the operation of the reversing rotating component, the material collection protection component is used to shield and protect the two filter cartridges, thereby isolating the filter cartridges from the filter chamber.

[0018] S4: The protective filter cartridge is dusted by the operation of the pulse dust collector. The dust separated from the surface of the filter cartridge will fall into the dust discharge hopper under the action of gravity through the material collection and protection components.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. By setting a reversing rotating component, the motor causes the movable slide plate to move up and down reciprocally, causing the annular jet pipe to spray intermittently, thereby improving the airflow around the annular jet pipe. This allows the dust entering the filter chamber to diffuse quickly, thus improving the utilization rate of the filter cartridge. As the movable slide plate moves up and down, the second contact plate first contacts and then separates from the first contact plate, causing the motor inside the first motor chamber to operate intermittently. During the operation of the motor inside the first motor chamber, the rotating gear ring rotates along the positioning internal gear ring, causing the filter cartridge to rotate relative to the turntable while rotating with it. This allows for adjustment of the position of the filter cartridge, preventing a large amount of dust entering the filter chamber from adsorbing onto the filter cartridge near the air inlet pipe, thus improving the dust filtration effect.

[0021] 2. By setting up a material collection protection component, when the trapezoidal extrusion plate moves upward, the first motor compartment stops operating first. Then, the V-shaped guide rail returns to its original position under the elastic restoring force of the fifth telescopic spring, thereby causing the retaining ring to move upward. At this time, the two semi-circular covers on the movable slider will block the filter cartridges located between the semi-circular covers. During this process, the material collection hopper moves downward under the action of the first inclined connecting rod. At this time, the bottom of the material collection hopper will squeeze the movable ring plate, thereby causing the blocking plate and the movable ring plate to misalign. When the semi-circular covers completely block the filter cartridges, the bottom of the semi-circular covers will be in contact with the top of the material collection hopper. At this time, the pulse dust collector will operate, and the operation of the pulse dust collector will remove dust from the filter cartridges between the semi-circular covers. At this time, the dust separated from the filter cartridges will enter the dust discharge pipe through the material collection hopper, movable ring plate, and positioning ring plate under the action of gravity, thereby preventing the air entering the filter chamber from affecting the dust removal effect on the surface of the filter cartridges.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. The following describes embodiments of the invention based on its overall structure.

[0034] Please see Figures 1 to 8 In this embodiment of the invention, a dust adsorption and filtration device for furniture board processing includes a filter chamber 1, an exhaust chamber 2 installed at the top of the filter chamber 1, a dust discharge chamber 4 installed at the bottom of the filter chamber 1, an air inlet pipe 5 extending through to the inner side of the filter chamber 1 on the outer wall of the filter chamber 1, an exhaust pipe 3 installed at the top of the exhaust chamber 2, a turntable 17 rotatably connected to the bottom of the exhaust chamber 2 via a bearing, a positioning plate 8 located above the turntable 17 installed on the inner side of the exhaust chamber 2, and a pulse dust collector installed on the positioning plate 8. 7. Multiple mounting sleeves 10 are provided on the turntable 17. The multiple mounting sleeves 10 are distributed at equal distances along the center of the turntable 17. A filter cylinder 16 located inside the filter chamber 1 is installed at the bottom of the mounting sleeve 10. A transverse connecting rod 12 located below the filter cylinder 16 is installed on the inner wall of the filter chamber 1. A reversing rotating component connected to the turntable 17 is provided on the transverse connecting rod 12. A rectangular guide rod 14 located above the transverse connecting rod 12 is installed on the inner wall of the filter chamber 1. A material collection protection component is installed on the rectangular guide rod 14.

[0035] In this embodiment: when dust enters the filter chamber 1 through the air inlet pipe 5, the air containing dust is filtered by the filter cartridge 16, causing the dust to adhere to the outer wall of the filter cartridge 16. At the same time, the filtered air enters the exhaust chamber 2 through the filter cartridge 16 and the mounting sleeve 10, and is finally discharged through the exhaust pipe 3. Then, the reversing rotating component is activated, and the operation of the reversing rotating component changes the position of the filter cartridge 16, which also causes the dust entering the filter chamber 1 to diffuse rapidly, preventing dust from accumulating on one filter cartridge 16. During the operation of the reversing rotating component, the two filter cartridges 16 are shielded and protected by the material collection protection component, realizing the isolation between the filter cartridges 16 and the filter chamber 1. Then, the pulse dust collector 7 is used to remove dust from the protected filter cartridges 16. At this time, the dust separated from the surface of the filter cartridges 16 will fall into the dust discharge chamber 4 under the action of gravity through the material collection protection component.

[0036] Please refer to this carefully. Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 The reversing rotating component includes a second motor housing 23 installed at the bottom of the transverse connecting rod 12. A reciprocating screw 22 connected to a motor inside the second motor housing 23 is installed at the top of the transverse connecting rod 12. Guide rods 26 located on both sides of the reciprocating screw 22 are installed at the top of the transverse connecting rod 12. A movable slide plate 19 is movably sleeved on the reciprocating screw 22. The movable slide plate 19 is slidably connected to the guide rods 26. A trapezoidal extrusion plate 24 is installed at the bottom of the movable slide plate 19. An annular jet pipe 27 located outside the reciprocating screw 22 is installed at the top of the movable slide plate 19. A corrugated telescopic plate 25 is connected to the top of the annular jet pipe 27. A first one-way valve 20 located above the turntable 17 is connected to the top of the annular jet pipe 27 via a pipe. A second one-way valve 29 located inside the corrugated telescopic plate 25 is installed at the top of the annular jet pipe 27. A second one-way valve 29 located inside the corrugated telescopic plate 25 is installed at the bottom of the transverse connecting rod 12. Below the second motor compartment 23 is the protective compartment 15. Inside the protective compartment 15 is a pressure rod 28 extending above the transverse connecting rod 12. At the bottom of the pressure rod 28 is a connecting plate 30 located inside the protective compartment 15. At the bottom of the connecting plate 30 is a first telescopic spring 31 connected to the inner wall of the protective compartment 15. At the bottom of the connecting plate 30 is a second contact piece 34 located on one side of the first telescopic spring 31. At the inner wall of the protective compartment 15 is a second telescopic spring 33 located below the second contact piece 34. At the top of the second telescopic spring 33 is a first contact piece 32. At the top of the positioning plate 8 is a first motor compartment 6 located on one side of the pulse dust collector 7. The output end of the motor inside the first motor compartment 6 is connected to the top of the turntable 17. At the top of the mounting sleeve 10 is a driven gear ring 9. At the inner wall of the exhaust compartment 2 is a positioning internal gear ring 11 that meshes with the driven gear ring 9.

[0037] In this embodiment: The motor inside the second motor compartment 23 is started, and the operation of the motor inside the second motor compartment 23 causes the reciprocating screw 22 to rotate, thereby causing the movable slide plate 19 on the reciprocating screw 22 to move up and down. When the movable slide plate 19 moves down along the reciprocating screw 22, it causes the corrugated expansion plate 25 to extend. The filtered air in the exhaust chamber 2 will enter the corrugated expansion plate 25 under the action of negative pressure through the first one-way valve 20. As the movable slide plate 19 moves down, the bottom of the trapezoidal extrusion plate 24 contacts the top of the pressure rod 28. At this time, the trapezoidal extrusion plate 24 continues to move down, and the pressure rod 28 will squeeze the connecting plate 30, so that the second contact piece 34 first contacts the first contact piece 32. Then the second contact piece 34 presses the first contact piece 32. When the second contact piece 34 contacts the first contact piece 32, the motor inside the first motor compartment 6 is energized and operates. At this time, the motor inside the first motor compartment 6... The machine will drive the turntable 17 to rotate. During this process, the rotating gear ring 9 rotates along the positioning internal gear ring 11, so that the filter cartridge 16 rotates relative to the turntable 17 while rotating with it. This allows the position of the filter cartridge 16 to be adjusted, preventing a large amount of dust entering the filter chamber 1 from adhering to the filter cartridge 16 near the air inlet pipe 5. When the movable slide plate 19 moves upward, the second contact piece 34 separates from the first contact piece 32 under the action of the first telescopic spring 31 and the second telescopic spring 33. At this time, the motor inside the first motor chamber 6 stops operating. At the same time, due to the upward movement of the movable slide plate 19, the pressure on the corrugated telescopic plate 25 causes the air inside the corrugated telescopic plate 25 to be discharged through the second one-way valve 29 and the annular jet pipe 27, thereby improving the airflow around the annular jet pipe 27. This allows the dust entering the filter chamber 1 to diffuse quickly, thereby improving the utilization rate of the filter cartridge 16.

[0038] Please refer to this carefully. Figure 4 , Figure 6 The second contact 34 is electrically connected to an external power supply via a wire, and the first contact 32 is electrically connected to the motor inside the first motor compartment 6 via a wire.

[0039] In this embodiment, the starting and stopping of the motor inside the first motor compartment 6 is achieved by the contact and separation of the second contact piece 34 and the first contact piece 32, thereby controlling the operating timing of the motor inside the first motor compartment 6.

[0040] Please refer to this carefully. Figure 6 The exhaust port of the first one-way valve 20 is connected to the top of the corrugated telescopic plate 25, and the exhaust port of the second one-way valve 29 is connected to the annular jet pipe 27.

[0041] In this embodiment, this structure enables unidirectional airflow inside the corrugated telescopic plate 25, allowing the annular jet pipe 27 to only perform jet processing.

[0042] Please refer to this carefully. Figure 3 , Figure 4 , Figure 7 , Figure 8 , Figure 9 The material collection protection component includes a dust discharge pipe 13 installed at the bottom of a rectangular guide rod 14 and connected to a dust discharge bin 4. Movable sliders 36 located on both sides of the dust discharge pipe 13 are slidably connected to the rectangular guide rod 14. A second inclined connecting rod 51 is rotatably connected to the top of the movable sliders 36 via a rotating shaft. A torsion spring 50 connected to the second inclined connecting rod 51 is engaged with the rotating shaft connected to the movable sliders 36 via a slot. A retaining ring 43 is rotatably connected to the top of the second inclined connecting rod 51 via a rotating shaft. A connecting rod 40 is installed on the side of the movable slider 36 away from the vertical central axis of the rectangular guide rod 14. A semi-circular cover 21 is installed on the top of the connecting rod 40. A first inclined connecting rod 39 is rotatably connected to one side of the connecting rod 40 via a rotating shaft. A material collection hopper 42 located inside the retaining ring 43 is rotatably connected to the end of the first inclined connecting rod 39 away from the connecting rod 40 via a rotating shaft. The bottom of the material collection hopper 42 extends to the dust discharge pipe 13. A rectangular guide rod 14 extends through the inner side of the dust discharge pipe 13. A third telescopic spring 38 connected to the top of the rectangular guide rod 14 is provided on the outer side of the collecting hopper 42. A positioning ring plate 45 is installed on the inner wall of the dust discharge pipe 13. A T-shaped frame 47 is installed on the inner wall of the positioning ring plate 45. A fourth telescopic spring 48 is provided on the top of the protective chamber 15. A movable ring plate 44 is connected to the top of the fourth telescopic spring 48. A blocking plate 46 that fits against the inner wall of the movable ring plate 44 is installed on the top of the T-shaped frame 47. A guide pin 37 is installed on the outer wall of the retaining ring 43. Telescopic tubes 18 located on both sides of the rectangular guide rod 14 are installed on the inner wall of the filter chamber 1. A V-shaped guide rail 41 located outside the guide pin 37 is provided at one end of the telescopic tube 18. The V-shaped guide rail 41 is divided into a horizontal section and an inclined section. A rotating roller 35 is installed at the end of the V-shaped guide rail 41 away from the telescopic tube 18. A fifth telescopic spring 49 is provided on the inner side of the telescopic tube 18.

[0043] In this embodiment: when the trapezoidal extrusion plate 24 moves downward with the movable slide plate 19, the trapezoidal extrusion plate 24 will first contact the rotating roller 35. At this time, the rotating roller 35 is squeezed by the inclined surface of the trapezoidal extrusion plate 24, causing the V-shaped guide rail 41 to move towards the telescopic tube 18. During the movement of the V-shaped guide rail 41, the inclined section of the V-shaped guide rail 41 squeezes the guide pin 37, thereby causing the guide pin 37 to drive the retaining ring 43 to move downward, thereby causing the movable slider 36 to move away from the collecting hopper 4. The filter cartridge 16 moves in the direction of 2, thereby removing the obstruction of the semi-circular cover 21 from the filter cartridge 16. Then, the V-shaped guide rail 41 continues to move downwards. When the trapezoidal extrusion plate 24 contacts the pressure rod 28, the guide pin 37 moves to the horizontal section of the V-shaped guide rail 41. At this time, when the trapezoidal extrusion plate 24 presses against the pressure rod 28, the horizontal height of the guide pin 37 remains unchanged, thus achieving the orderly rotation of the filter cartridge 16 and the movement of the semi-circular cover 21. When the trapezoidal extrusion plate 24 moves upwards, the motor inside the first motor compartment 6 stops operating. After the operation, the V-shaped guide rail 41 returns to its original position under the elastic restoring force of the fifth telescopic spring 49, thereby causing the retaining ring 43 to move upward. At this time, the two semi-circular covers 21 on the movable slider 36 will block the filter cylinder 16 located between the semi-circular covers 21. During this process, the collecting hopper 42 moves downward under the action of the first inclined connecting rod 39. At this time, the bottom of the collecting hopper 42 will squeeze the movable ring plate 44, thereby causing the blocking plate 46 to be misaligned with the movable ring plate 44. When the semi-circular covers 21 are completely closed... When the filter cartridge 16 is covered, the bottom of the semi-circular cover 21 is in contact with the top of the collection hopper 42. At this time, the pulse dust collector 7 is in operation. The operation of the pulse dust collector 7 removes dust from the filter cartridge 16 between the semi-circular covers 21. The dust separated from the filter cartridge 16 will enter the dust discharge pipe 13 through the collection hopper 42, the movable ring plate 44, and the positioning ring plate 45 under the action of gravity. This is to prevent the air entering the filter chamber 1 from affecting the dust removal effect on the surface of the filter cartridge 16.

[0044] Please refer to this carefully. Figure 8 The diameter of the top of the collecting hopper 42 is equal to the diameter of the semi-circular cover 21, and the diameter of the bottom of the collecting hopper 42 is greater than the diameter of the inner wall of the movable ring plate 44.

[0045] In this embodiment, by setting this structure, the hopper 42 is connected to the dust discharge chamber 4 through the dust discharge pipe 13 when it moves down, and at the same time, the sealing performance of the semi-circular cover 21 around the filter cartridge 16 is improved.

[0046] Please refer to this carefully. Figure 4 , Figure 7 The diameter of the semi-circular cover 21 is larger than the diameter of the filter cylinder 16.

[0047] In this embodiment, this structure is designed so that when the semi-circular cover 21 covers the area around the filter cartridge 16, there is still a gap between the filter cartridge 16 and the semi-circular cover 21, thereby providing space for dust to fall.

[0048] Please refer to this carefully. Figure 9 The guide pin 37 is slidably connected to the inner side of the V-shaped guide rail 41, and the telescopic distance of the telescopic tube 18 is equal to the length of the V-shaped guide rail 41.

[0049] In this embodiment: by setting this structure, when the V-shaped guide rail 41 moves horizontally, the V-shaped guide rail 41 squeezes the guide pin 37 through the inclined section, so that the retaining ring 43 can only move upward or downward.

[0050] Please refer to this carefully. Figure 4 The rectangular guide rod 14 is located below the pulse dust collector 7, and the center of the collection hopper 42 is coaxial with the center of the filter cartridge 16 located above the collection hopper 42.

[0051] In this embodiment, this structure is designed so that the pulse dust collector 7 will always clean the dust on the surface of the filter cartridge 16, which is covered by the semi-circular cover 21, when it is in operation.

[0052] The following describes a method for adsorbing and filtering dust from furniture board processing, based on the aforementioned dust adsorption and filtration device. The method includes the following steps:

[0053] S1: When dust enters the filter chamber 1 through the air inlet pipe 5, the air containing dust is filtered through the filter cartridge 16, causing the dust to adhere to the outer wall of the filter cartridge 16. At the same time, the filtered air enters the exhaust chamber 2 through the filter cartridge 16 and the mounting sleeve 10, and is finally discharged through the exhaust pipe 3.

[0054] S2: Start the motor inside the second motor compartment 23. The operation of the motor inside the second motor compartment 23 causes the reciprocating screw 22 to rotate, thereby causing the movable slide plate 19 on the reciprocating screw 22 to move up and down. When the movable slide plate 19 moves down along the reciprocating screw 22, it causes the corrugated expansion plate 25 to extend. The filtered air in the exhaust chamber 2 will enter the corrugated expansion plate 25 under the action of negative pressure through the first one-way valve 20. As the movable slide plate 19 moves down, the bottom of the trapezoidal extrusion plate 24 contacts the top of the pressure rod 28. At this time, the trapezoidal extrusion plate 24 continues to move down, and the pressure rod 28 will squeeze the connecting plate 30, so that the second contact piece 34 first contacts the first contact piece 32. Then the second contact piece 34 presses the first contact piece 32. When the second contact piece 34 contacts the first contact piece 32, the motor inside the first motor compartment 6 is energized and operates. At this time, the motor inside the first motor compartment 6... This will cause the turntable 17 to rotate. During this process, the rotating gear ring 9 rotates along the positioning internal gear ring 11, so that the filter cartridge 16 rotates relative to the turntable 17 while rotating with it. This allows the position of the filter cartridge 16 to be adjusted, preventing a large amount of dust entering the filter chamber 1 from adhering to the filter cartridge 16 near the air inlet pipe 5. When the movable slide plate 19 moves upward, the second contact piece 34 and the first contact piece 32 separate under the action of the first telescopic spring 31 and the second telescopic spring 33. At this time, the motor inside the first motor chamber 6 stops operating. At the same time, due to the upward movement of the movable slide plate 19, the pressure on the corrugated telescopic plate 25 causes the air inside the corrugated telescopic plate 25 to be discharged through the second one-way valve 29 and the annular jet pipe 27, thereby improving the airflow around the annular jet pipe 27. This allows the dust entering the filter chamber 1 to diffuse quickly, thereby improving the utilization rate of the filter cartridge 16.

[0055] S3: When the trapezoidal extrusion plate 24 moves downward with the movable slide plate 19, the trapezoidal extrusion plate 24 will first contact the rotating roller 35. At this time, the rotating roller 35 is squeezed by the inclined surface of the trapezoidal extrusion plate 24, causing the V-shaped guide rail 41 to move towards the telescopic tube 18. During the movement of the V-shaped guide rail 41, the inclined section of the V-shaped guide rail 41 squeezes the guide pin 37, thereby causing the guide pin 37 to drive the retaining ring 43 to move downward, thereby causing the movable slider 36 to move away from the collection hopper 42, so that the semi-circular cover 21 loses its obstruction of the filter cylinder 16. Then the V-shaped guide rail 41 continues to move downward. When the trapezoidal extrusion plate 24 contacts the pressure rod 28, the guide pin 37 moves to the horizontal section of the V-shaped guide rail 41. At this time, the trapezoidal extrusion plate 24 presses the pressure rod 28. The horizontal height of the guide pin 37 remains unchanged, thereby achieving the orderly rotation of the filter cylinder 16 and the movement of the semi-circular cover 21. When the trapezoidal extrusion plate 24 moves upward, the motor inside the first motor chamber 6 stops operating first. Then, the V-shaped guide rail 41 returns to its original position under the elastic restoring force of the fifth telescopic spring 49, thereby causing the retaining ring 43 to move upward. At this time, the two semi-circular covers 21 on the movable slider 36 will block the filter cylinder 16 located between the semi-circular covers 21. During this process, the collecting hopper 42 moves downward under the action of the first inclined connecting rod 39. At this time, the bottom of the collecting hopper 42 will squeeze the movable ring plate 44, thereby causing the blocking plate 46 and the movable ring plate 44 to be misaligned. When the semi-circular cover 21 completely blocks the filter cylinder 16, the bottom of the semi-circular cover 21 is in contact with the top of the collecting hopper 42.

[0056] S4: Start the pulse dust collector 7. The operation of the pulse dust collector 7 removes dust from the filter cartridges 16 between the semi-circular covers 21. At this time, the dust separated from the filter cartridges 16 will enter the dust discharge pipe 13 through the collection hopper 42, the movable ring plate 44, and the positioning ring plate 45 under the action of gravity. This is to prevent the air entering the filter chamber 1 from affecting the dust removal effect on the surface of the filter cartridges 16. The operation of the pulse dust collector 7 removes dust from the protected filter cartridges 16. At this time, the dust separated from the surface of the filter cartridges 16 will fall into the dust discharge chamber 4 through the collection protection component under the action of gravity.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
