Description

Technical Field

[0001] This invention relates to the field of wood dust recycling technology, specifically to a device for recycling and reusing wood dust and processed wood board dust. Background Technology

[0002] In the wood processing industry, processes such as cutting, sanding, and drilling wood panels generate a large amount of sawdust and dust waste. Directly discarding this waste not only results in a serious waste of wood resources, but also pollutes the workshop environment. Long-term inhalation of this dust can easily cause respiratory diseases and harm the health of operators. Furthermore, sawdust often contains impurities such as nails and metal shavings that have fallen off during processing. Existing recycling equipment struggles to achieve efficient separation, resulting in low-purity recycled sawdust that cannot be directly used in particleboard production, biomass fuel processing, or other recycling applications.

[0003] A search revealed Chinese patent CN114474257B, which discloses an anti-clogging wood processing wood chip collection device capable of centrally sucking in and collecting wood chips. This anti-clogging wood processing wood chip collection device includes: a cabinet with a workbench on top; a first collection box located at the bottom of the cabinet for collecting wood chips; a dustproof door rotating on the front of the cabinet; a suction component inside the cabinet for sucking in wood chips; and a cutting component with a cutting component on the suction component for secondary crushing of the wood chips. An exhaust fan, through a diffuser, sucks the wood chips generated during the wood cutting process into the feed pipe. The wood chips in the feed pipe then fall into a protective cover. The crushed wood chips are then discharged from the discharge pipe into the first collection box for centralized collection under the action of the exhaust fan.

[0004] Traditional recycling equipment suffers from several shortcomings: First, its collection end structure is simplistic, only suitable for collecting a single type of dust. It is ineffective for collecting dust from narrow areas such as gaps and corners in boards, or from large areas of the ground, demonstrating insufficient adaptability. Second, it lacks grading and separation capabilities, resulting in the mixed recycling of wood chips of different particle sizes, reducing the targeted nature and value of recycling. Third, wood chips often contain impurities such as nails and metal shavings that have detached during processing. Existing recycling equipment struggles to achieve efficient separation, leading to low purity wood chips and potential damage to the collection device. Currently, there is a lack of highly efficient recycling equipment that can simultaneously address impurity separation, multi-scenario collection, anti-clogging, grading storage, and convenient retrieval; therefore, targeted improvements are urgently needed.

[0025] In an optional embodiment, the control unit 12 integrates a wind pressure sensor and a timing module. The wind pressure sensor is installed on the air inlet side of the negative pressure screen cylinder 8 to monitor the filter screen clogging in real time. When the wind pressure value exceeds a preset threshold, the control unit 12 automatically accelerates the start of the drive motor of the cleaning mechanism 9, driving the cleaning brush 92 to rotate faster for cleaning. After the wind pressure value drops to the normal threshold during the cleaning process, the drive motor operates normally. The timing module can preset the accelerated cleaning interval, providing double protection to prevent filter screen clogging.

[0026] In this embodiment, the design enables the intelligent operation of the cleaning mechanism 9, avoiding energy waste caused by ineffective work, while ensuring continuous and stable operation of the equipment and reducing the frequency of manual inspections.

[0027] In an optional embodiment, a rubber buffer pad is attached to the inner side of the guide port 21 of the first sedimentation tank 2. The surface of the buffer pad is provided with anti-slip texture, which can slow down the impact speed of the dust-laden airflow, reduce the probability of metal impurities bouncing, and reduce the noise generated by the airflow impact.

[0028] In this embodiment, the buffer pad not only improves the adsorption efficiency of metal impurities but also optimizes the operating environment of the equipment, meeting the requirements for noise reduction in the workshop.

[0029] In an optional embodiment, the collection end 3 includes an adsorption rod 31 and an adsorption bucket 32. The adsorption rod 31 is a long, hollow shell with adsorption holes on its side. The adsorption bucket 32 ​​is a hollow shell with one end open. Both the adsorption rod 31 and the adsorption bucket 32 ​​are connected to the inlet end of the first sedimentation tank 2 through pipes. Solenoid valves are provided at the positions where the adsorption rod 31 and the adsorption bucket 32 ​​are connected to the pipes. The solenoid valves are electrically connected to the control unit 12.

[0030] In this embodiment, the control unit 12 enables the solenoid valve connecting the adsorption rod 31 and the adsorption bucket 32 ​​to be selectively opened, allowing the collection end 3 to adapt to different working environments and improving the versatility of the equipment.

[0031] In an optional embodiment, a baffle is provided inside the storage compartment 10. The baffle is a honeycomb structure composed of horizontal and vertical strips, which can prevent falling dust from being sucked up again by the negative pressure airflow, ensuring that the dust is successfully deposited in the extraction box 11.

[0032] In this embodiment, the baffle further improves dust collection efficiency, reduces airflow interference to the storage process, and increases dust recovery rate.

[0033] In an optional embodiment, the cyclone cone 5 includes a cone-shaped cylinder 51 and a guide plate 52. The cone-shaped cylinder 51 is a cone-shaped hollow shell. The cone-shaped cylinder 51 is fixedly installed on the upper end of the second sedimentation tank 4. A filter screen is provided at the lower end of the cone-shaped cylinder 51. A spiral guide plate 52 is fixedly connected to the outer surface of the cone-shaped cylinder 51. The first sedimentation tank 2 and the guide plate 52 are connected through a pipe.

[0034] In this embodiment, the spiral guide plate 52 can guide the dust-laden airflow to flow spirally downward along the inner wall of the second sedimentation tank 4, and use centrifugal force to throw larger dust particles toward the tank wall, thereby achieving the initial separation of large dust particles from the airflow; the filter screen at the lower end of the conical cylinder 51 can intercept large dust particles, and at the same time provide a cleaning surface for the agitator 13, ensuring that the filter screen is unobstructed and improving the separation effect.

[0035] In an optional embodiment, there is a gap between the outer wall of the separation cylinder 6 and the inner wall of the second sedimentation cylinder 4, a through hole is provided at the center of the bottom of the separation cylinder 6, the upper edge of the separation cylinder 6 is fixedly connected to the second sedimentation cylinder 4, and a separation notch 61 is provided on the surface of the separation cylinder 6.

[0036] In this embodiment, the gap between the inner wall of the separation cylinder 6 and the second sedimentation cylinder 4 provides a dedicated falling channel for larger dust particles, the separation notch 61 allows medium-sized dust particles to pass through, achieving preliminary classification of dust particles of different sizes, and the bottom through hole provides installation space for the stirring shaft 131, ensuring the normal operation of the stirring mechanism 13.

[0037] In an optional embodiment, the stirring mechanism 13 includes a stirring shaft 131, a winch blade 132, and a shielding rod 133. The stirring shaft 131 passes through a through hole in the center of the separation cylinder 6. A paddle is provided at the upper end of the stirring shaft 131, and the paddle contacts the filter screen at the bottom end of the conical cylinder 51. The winch blade 132 is fixedly connected to the surface of the stirring shaft 131. The winch blade 132 contacts the inner wall of the separation cylinder 6. One side of the winch blade 132 is attached to the inner wall of the separation cylinder 6, and the other side is raised. The shielding rod 133 is fixedly connected to the outer surface of the lower end of the stirring shaft 131. The shielding rod 133 is located between the outer wall of the separation cylinder 6 and the inner wall of the second sedimentation tank 4. The shielding rod 133 is curved.

[0038] In this embodiment, the paddle can clean the dust from the bottom filter screen of the conical cylinder 51 in real time to prevent the filter screen from clogging; the special structure of the winch 132 can lift the dust from the inner wall of the separation cylinder 6 upward and then let it fall down, so that the dust is resuspended, making it easier for the filter screen of the conical cylinder 51 to further adsorb fine dust; the arc-shaped shielding rod 133 can disturb the airflow in the gap, promote the falling of larger dust particles, and at the same time separate an independent particle collection space to achieve graded storage.

[0039] In an optional embodiment, the negative pressure mesh cylinder 8 is cylindrical in shape. One end of the negative pressure mesh cylinder 8 is connected to the negative pressure fan, and the other end is closed. A filter mesh is provided on the outer circumference of the negative pressure mesh cylinder 8 near the closed end. The filter mesh is located above the conical cylinder 51.

[0040] In this embodiment, the cylindrical structure and the design of the side filter mesh increase the airflow contact area and improve the efficiency of fine dust interception; the filter mesh is located above the conical cylinder 51, which can accurately capture the residual fine dust in the airflow after separation by the second sedimentation tank 4, and achieve deep dust purification.

[0041] In an optional embodiment, the cleaning mechanism 9 includes a rotating disk 91 and a cleaning brush 92. The rotating disk 91 is rotatably connected to the closed end of the negative pressure mesh cylinder 8. The cleaning brush 92 is fixedly connected to the surface of the rotating disk 91 and is spirally wound around the outer surface of the negative pressure mesh cylinder 8.

[0042] In this embodiment, the spiral cleaning brush 92 can fully cover the outer surface of the negative pressure mesh cylinder 8 when it rotates, with no dead corners. At the same time, the thrust generated by the spiral rotation can push the dust along the spiral direction, making it easier for the dust to pass over the isolation block 71 and fall into the storage chamber 10, so that cleaning and collection can be carried out simultaneously.

[0043] When using the device, first move it near the woodworking machine tool. Then, use the touch screen of the control unit 12 to select the adsorption mode and control the solenoid valves of the adsorption rod 31 and the adsorption bucket 32. To recycle dust from narrow areas such as gaps and corners of the board, open the solenoid valve corresponding to the adsorption rod 31. To recycle dust from large areas such as the surface of the board or the ground, open the solenoid valve corresponding to the adsorption bucket 32. If simultaneous recycling is required, both solenoid valves can be opened. By starting the negative pressure fan, under negative pressure, sawdust enters the pipe through the collection end 3 and is guided into the first sedimentation tank 2 through the guide port 21. Metal impurities in the airflow fall along the guide port 21 under the action of gravity and are adsorbed by the magnetic box 22. Large impurities are deposited at the bottom of the first sedimentation tank 2 and can be cleaned by pulling the magnetic box 22. The dust-laden airflow after preliminary separation in the first sedimentation tank 2 enters the cyclone cone 5 of the second sedimentation tank 4 through the pipe. Guided by the guide plate 52, it flows spirally downward along the inner wall of the second sedimentation tank 4. Centrifugal force throws the dust against the tank wall, and larger dust particles fall along the tank wall and reach the bottom of the separation tank 6 through the edge gap. At the same time, the control unit 12 starts the motor of the stirring mechanism 13, which drives the stirring shaft 131 to rotate. The shielding rod 133 rotates and disturbs the separation tank 6. The gap between the outer wall and the inner wall of the second sedimentation tank 4 promotes the falling of larger particles into the storage chamber 10. After the powder flows out through the guide plate 52, it is adsorbed by the conical cylinder 51. The filter screen at the bottom of the conical cylinder 51 is cleaned by the paddle at the upper end of the stirring shaft 131 to prevent the filter screen from being blocked. The wood chips that have been cleaned and enter the separation tank 6 are moved by the winch 132. The winch 132 lifts the dust on the inner wall of the separation tank 6 upward and then falls down. The wood chips and dust are lifted up again and adsorbed by the filter screen of the conical cylinder 51. The granular wood chips enter the separation opening 61 and are moved to the bottom of the separation tank 6 by the shielding rod 133. They are blocked by the arc-shaped separation tank 6 and the arc-shaped shielding rod 133. The shielding rod 133 is divided into upper and lower spaces by the separation tank 6. The larger wood chips enter the independent extraction box 11. The dust and wood chips are adsorbed by the conical cylinder 51. After separation in the second sedimentation tank 4, the airflow flows upward and enters the negative pressure fan through the filter mesh of the negative pressure screen cylinder 8. Fine dust particles in the airflow are intercepted by the filter mesh and adsorbed onto the surface of the negative pressure screen cylinder 8. The control unit 12 activates the drive motor of the cleaning mechanism 9, causing the rotating disk 91 to rotate. The cleaning brush 92 rotates spirally along the outer surface of the negative pressure screen cylinder 8, pushing the adsorbed dust along the spiral direction. After the dust is pushed past the isolation block 71, the adsorption force disappears, and it falls into the storage chamber 10. The storage chamber 10 is equipped with a baffle to prevent the falling dust from being sucked up again. The baffle is controlled by the control unit 12. The thickness of the separator 71 is spaced apart from the spiral cleaning brush 92, and the suction force is greatly reduced after passing the separator 71 by the rotation of the cleaning brush 92, ensuring that the dust can enter the storage chamber 10 and fall into the corresponding extraction box 11. The first sedimentation tank 2 is set to remove metal impurities in the wood chips. The second sedimentation tank 4, the cyclone cone 5 and the separation tank 6 work together to separate wood chips of different particle diameters. The cleaning mechanism 9 cleans and collects the wood chip dust on the surface of the negative pressure mesh cylinder 8, so that the wood chips can be graded and collected, and the recycled wood chips can be directly reused in different fields.
