Description

Technical Field

[0001] The invention relates to the technical field of dust adsorption and filtration, and in particular to a dust adsorption and filtration device and method for furniture board processing. Background Art

[0002] Plates are flat rectangular building material boards made of standard sizes and are used in the construction industry. They are used to make walls, ceilings or floors. They mostly refer to metal plates made of forged, rolled or cast metal plates. They are divided into thin plates, medium plates, thick plates, and extra-thick plates. They are usually made into flat rectangular building material boards of standard sizes. When processing some wooden plates, a large amount of dust and debris will be generated. At this time, in order to prevent the dust from affecting the working environment, the dust needs to be adsorbed and filtered.

[0003] Generally, the dust-laden air is sucked into the dust collector through an air pump, and then the dust in the gas is filtered through a filter cartridge. After the filtration is completed, the dust attached to the surface of the filter cartridge is separated from the filter cartridge through a pulse dust collector. However, since the filter cartridge close to the air inlet will first come into contact with the dust-laden air, a certain amount of dust will accumulate on its surface after long-term use, resulting in a decrease in the filtration efficiency. When the filter cartridge is cleaned by the pulse emitted by the pulse dust collector, since the filter cartridge is always in the filter chamber, the dust-laden air will enter the filter chamber and blow the dust separated from the filter cartridge, which will cause the dust to attach to other filter cartridges again, which will not only affect the cleaning effect of the filter cartridge surface, but also affect the filtration effect of subsequent filter cartridges.

A trapezoidal extrusion plate 24 is installed at the bottom of the movable slide 19, and an annular jet pipe 27 located outside the reciprocating screw 22 is installed on the top of the movable slide 19. A corrugated telescopic plate 25 is connected to the top of the annular jet pipe 27. The top of the corrugated telescopic plate 25 is connected to a first one-way valve 20 located above the turntable 17 through a pipeline. A second one-way valve 29 located inside the corrugated telescopic plate 25 is installed on the top of the annular jet pipe 27. The protection bin 15 below the second motor bin 23 has a pressure rod 28 extending to the top of the transverse connecting rod 12 inserted into the inner side of the protection bin 15, and a connecting plate 30 located on the inner side of the protection bin 15 is installed at the bottom of the pressure rod 28.

As the movable slide plate 19 moves downward, 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 downward, and the pressure rod 28 squeezes the connecting plate 30, so that the second contact piece 34 contacts the first contact piece 32 first, and 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 rotating disk 17 is driven to rotate, and in this process, the rotating gear ring 9 rotates along the positioning inner gear ring 11, so that the filter cartridge 16 rotates relative to the rotating disk 17 while rotating with the rotating disk 17, so that the position of the filter cartridge 16 can be adjusted to prevent a large amount of dust entering the filter bin 1 from being adsorbed on the filter cartridge 16 near the air inlet pipe 5. When the movable slide plate 19 moves up, the second contact piece 34 and the first contact piece 32 are separated under the action of the first telescopic spring 31 and the second telescopic spring 33. At this time, the motor inside the first motor bin 6 stops operating. At the same time, due to the squeezing of the corrugated telescopic plate 25 by the upward movement of the movable slide plate 19, the air inside the corrugated telescopic plate 25 is discharged through the second one-way valve 29 and the annular jet pipe 27, so as to improve the fluidity of the gas around the annular jet pipe 27, so that the dust entering the filter bin 1 can be quickly diffused, so as to improve the utilization rate of the filter cartridge 16. S3: When the trapezoidal extrusion plate 24 moves downward with the movable slide plate 19, the trapezoidal extrusion plate 24 will first contact the roller 35. At this time, the roller 35 is squeezed by the inclined surface of the trapezoidal extrusion plate 24, so that the V-shaped guide rail 41 moves toward the telescopic tube 18. During the movement of the V-shaped guide rail 41, the guide pin 37 is squeezed by the inclined section of the V-shaped guide rail 41, so that the guide pin 37 drives the retaining ring 43 to move downward, so that the movable slider 36 moves in the direction away from the collecting hopper 42, so that the semicircular cover 21 loses its shielding of the filter cartridge 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. When the guide pin 37 is horizontally height-remained unchanged, the filter cartridge 16 rotates and the semicircular cover 21 moves in an orderly manner. When the trapezoidal extrusion plate 24 moves upward, the motor inside the first motor compartment 6 stops operating first, and then the V-shaped guide rail 41 recovers under the elastic restoring force of the fifth telescopic spring 49, so that the snap ring 43 moves upward. At this time, the two semicircular covers 21 on the movable slider 36 will block the filter cartridge 16 located between the semicircular covers 21. During this process, the collecting hopper 42 moves downward under the action of the first oblique connecting rod 39. At this time, the bottom of the collecting hopper 42 will squeeze the movable ring plate 44, so that the blocking plate 46 and the movable ring plate 44 are misaligned. When the semicircular cover 21 completely blocks the filter cartridge 16, the bottom of the semicircular cover 21 fits with the top of the collecting hopper 42. S4: Start the pulse dust collector 7, and remove dust from the filter cartridge 16 between the semicircular cover 21 through the operation of the pulse dust collector 7. At this time, the dust separated from the filter cartridge 16 will enter the dust exhaust pipe 13 through the collecting hopper 42, the movable ring plate 44, and the positioning ring plate 45 under the action of gravity, so as to prevent the air entering the filter bin 1 from affecting the dust removal effect on the surface of the filter cartridge 16. The protected filter cartridge 16 is removed from dust through the operation of the pulse dust collector 7. At this time, the dust separated from the surface of the filter cartridge 16 will fall into the dust exhaust bin 4 through the collecting protection part under the action of gravity.
