Description
Technical Field
[0001] The present invention relates to the technical field of woodworking machinery dust treatment, and in particular to an innovative process for efficient collection and purification of woodworking machinery dust. Background Art
[0002] In the woodworking industry, operations such as wood cutting, milling, and sanding generate large amounts of dust. This dust not only seriously impacts workshop air quality and harms workers' health, but long-term inhalation can lead to respiratory diseases and pneumoconiosis. It also poses safety risks such as dust explosions. Furthermore, untreated, released dust can cause environmental pollution.
[0003] At present, the existing dust collection devices for woodworking machinery have many shortcomings when dealing with dust problems. Since woodworking dust particles vary in size and some dust has a certain viscosity, fine dust easily adheres to filter elements and other filter components during the filtration process. As time goes by, it gradually accumulates, causing the filtration resistance to increase and the purification efficiency to drop sharply. The structural design of the filter components of most devices is not conducive to disassembly and cleaning, and cleaning and maintenance often require a lot of manpower and time costs. Moreover, some traditional cleaning methods, such as simple manual wiping or single backflushing cleaning, are not ideal. It is difficult to completely remove the dust attached to the filter components and it is impossible to effectively restore the performance of the filter components, which shortens the service life of the entire dust collection device. Frequent replacement of filter components also increases the operating costs of the company. Summary of the Invention

The cleaning mechanism includes a bearing seat 19, the bottom end of the bearing seat 19 is provided on the upper surface of the filter barrel 9, and the upper surface of the bearing seat 19 is provided with a blower 8. The output end of the blower 8 is fixedly provided with an air duct 15, one end of the air duct 15 is provided with a bearing 22, and the outer wall of the bearing 22 is provided on the top of the rotating shaft 23. The driving mechanism includes a motor 17, the outer wall of the motor 17 is provided on the upper surface of the filter barrel 9, and the output end of the motor 17 is fixedly provided with a bevel gear 1 24, the tooth end of the bevel gear 1 24 is meshed and connected with a bevel gear 2 25, and the middle part of the bevel gear 25 is fixedly provided on the outer wall of the rotating shaft 23.
[0034] Specifically, first, in the dust collection stage, the device uses the centrifugal fan 4 arranged on the upper surface of the box 1, and uses the dust suction pipe and the dust suction hood 2 to suck the dust-laden air generated during the operation of the woodworking machinery into the device. The dust-laden air is then transported to the centrifugal dust collecting bucket 6 for preliminary dust separation treatment. Large particles of dust are separated from the air under the action of centrifugal force and settled and collected. The air after preliminary purification enters the filter barrel 9 through the conveying pipe 7.
[0035] After the air enters the filter barrel 9, it needs to rely on the filter element 20 to further achieve the purpose of purification. The filter element 20 plays a core filtering role in this process. It has the ability to intercept fine dust in the air, allowing clean air to pass through the filter element 20 smoothly, while the dust in the dusty air is trapped on the surface and inside of the filter element 20, thereby achieving deep purification of the air. The clean air filtered by the filter element 20 will be discharged from the filter barrel 9 through the exhaust pipe 16 set on the upper surface of the filter barrel 9, thus completing the air purification process in the filter barrel 9.
[0036] Support base 19 is securely mounted on the upper surface of filter drum 9, providing mounting support for blower 8. Blower 8 is placed on the upper surface of support base 19, its output end tightly connected to air duct 15, one end of which is connected to bearing 22 at the top of rotating shaft 23. When blower 8 is activated, it generates airflow at a certain pressure and velocity. This airflow is transmitted along the internal channel of air duct 15, passes through bearing 22, and enters the interior space of rotating shaft 23, providing the air source for subsequent cleaning operations.
[0037] Motor 17 is mounted at a specific location on the upper surface of filter drum 9. When motor 17 is started, bevel gear 1 24, fixed to its output end, begins to rotate about its own axis. Bevel gear 1 24 and bevel gear 2 25 are meshed together for transmission. Because the center of bevel gear 2 25 is fixed to the outer wall of rotating shaft 23, when bevel gear 1 24 rotates, it drives meshed bevel gear 2 25 to rotate synchronously, thereby driving rotating shaft 23 to rotate about its axis.
[0038] As the shaft 23 rotates, the connecting tubes 1 (26) and 2 (30) mounted on the outer wall of the shaft 23 also rotate. Brush plate 2 (27), connected to one end of connecting tube 1 (26), rotates in a circular motion in sync with the rotation of connecting tube 1 (26). During this motion, the bristles 1 (28) on one side of brush plate 27 come into close contact with the inner wall of the filter element 20. The friction between the bristles and the inner wall of the filter element 20 cleans away dust adhering to the inner wall of the filter element 20. Simultaneously, the air nozzles 1 (29) mounted on both ends of brush plate 27 also move as the brush plate 27 rotates. During this movement, since the airflow from blower 8 passes through the shaft 23 and connecting tube 1 (26) and successfully reaches air nozzles 1 (29), air nozzles 1 (29) spray air toward the inner wall of the filter element 20, blowing away the dust removed by the bristles 1 (28) and freeing it from the inner wall of the filter element 20.
[0039] Similarly, brush plate 1 21, connected to one end of connecting pipe 2 30 symmetrically disposed at the bottom end of rotating shaft 23, also performs circular motion as rotating shaft 23 rotates. Brush bristles 2 32 on the sidewalls of brush plate 1 21 come into contact with the outer wall of filter element 20, sweeping away dust adhering to the outer wall of filter element 20. Similarly, air nozzles 2 31 at both ends of the sidewalls of brush plate 1 21 spray airflow from blower 8 toward the outer wall of filter element 20 as brush plate 1 21 rotates, blowing away the dust swept away by bristles 2 32 and freeing it from the outer wall of filter element 20. The blown-off dust, under the influence of gravity and the airflow within the device, falls into dust hopper 18, then reenters centrifugal dust collection barrel 6 through conveying pipe 2 10. Within centrifugal dust collection barrel 6, the dust further settles due to its centrifugal action, ultimately falling into dust box 14, thereby effectively cleaning filter element 20, preventing clogging, and facilitating subsequent maintenance operations. This cyclic dust collection and treatment mechanism helps to further improve the dust collection and treatment efficiency of the entire device and the cleaning and maintenance effect of the filter element 20.
[0040] Through the close coordination between the cleaning mechanism and the driving mechanism, the device can automatically and timely clean the filter element 20 during operation and use airflow to blow away dust. This prevents dust from accumulating on the surface and inside of the filter element 20, maintaining the good filtration performance of the filter element 20 over a long period of time, and effectively avoiding the problem of reduced purification efficiency caused by clogging of the filter element 20. This ensures that the entire device can continuously and stably collect and purify dust, guaranteeing the long-term stable operation and good working efficiency of the device. This solves the problem of filter components being easily clogged and difficult to maintain.
[0041] Please see the attached Figure 1 , Attachment Figure 3 -Attached Figure 4 , Attachment Figure 6 The upper surface of the filter barrel 9 is provided with a plurality of exhaust pipes 16 , and the bottom end of the exhaust pipe 16 passes through the filter barrel 9 and is provided inside the filter element 20 .
[0042] Specifically, during the operation of the woodworking machinery dust collection device, when dust-laden air enters the filter barrel 9, it first contacts the filter element 20. The filter element 20 is like a fine sieve that has the function of intercepting dust, and can block dust in the air on the surface and internal pores of the filter element 20, while clean air will pass through the filter element 20.
[0043] The exhaust ducts 16 located on the upper surface of the filter barrel 9 play a key role. The bottom ends of the exhaust ducts 16 penetrate the filter barrel 9 and extend into the interior of the filter element 20, providing an exhaust channel for the clean air filtered by the filter element 20. During operation, the centrifugal fan 4 creates a certain pressure differential within the device. This pressure differential allows the air purified by the filter element 20 to smoothly exit the filter barrel 9 through the exhaust ducts 16, ultimately discharging the clean air into the external environment or for subsequent recycling.
[0044] The exhaust pipe 16 on the filter barrel 9 can efficiently discharge clean air, maintain the air pressure balance inside the device, and ensure the normal operation of the filter element 20. This achieves many beneficial effects, such as efficient discharge of clean air, ensuring stable operation of the device, extending the service life of the filter element 20, and improving overall purification efficiency. It makes the discharged air more in line with relevant standards, helps improve the workshop environment and reduce environmental pollution. It solves the problem of poor air discharge and poor purification effect.
[0045] Please see the attached Figure 1 , Attachment Figure 3 -Attached Figure 5 A dust collecting hopper 18 is provided at the bottom end of the filter barrel 9, a conveying pipe 2 10 is provided at the bottom end of the dust collecting hopper 18, a centrifugal dust collecting barrel 6 is provided at one end of the conveying pipe 2 10, the outer wall of the centrifugal dust collecting barrel 6 is provided inside the box body 1, and a conveying pipe 1 7 is provided at the top of the centrifugal dust collecting barrel 6, and one end of the conveying pipe 1 7 is provided on the outer wall of the filter barrel 9.
[0046] Specifically, during the operation of the efficient dust collection device for woodworking machinery, the filter barrel 9 plays a key filtering role. When dust-laden air enters the filter barrel 9, the dust is intercepted by the filter element 20 inside the filter barrel 9, while the clean air is discharged through the exhaust pipe 16. At the same time, a dust hopper 18 is provided at the bottom of the filter barrel 9. It has a funnel-shaped structure that is wide at the top and narrow at the bottom. Its purpose is to collect dust that falls from the filter element 20 or settles due to gravity inside the filter barrel 9.
[0047] The bottom end of dust hopper 18 is connected to conveying pipe 2 10, a relatively airtight conduit that provides a path for dust to be transported. During operation, dust collected in dust hopper 18 is transported along conveying pipe 2 10 to the centrifugal dust collection bucket 6 connected to one end, driven by gravity and any slight air pressure differences (e.g., caused by the subsequent operation of centrifugal dust collection bucket 6).
[0048] The outer wall of the centrifugal dust collection bucket 6 is disposed within the housing 1. Its internal structure allows for the separation of dust and air through the powerful centrifugal force generated by the high-speed rotation of the dust-laden airflow. When dust transported from the delivery pipe 2 10 enters the centrifugal dust collection bucket 6, the centrifugal force propels the dust toward the bucket walls and gradually settles to the bottom of the bucket under the action of gravity, further separating the dust from the air.
[0049] A conveying pipe 7 is provided at the top of the centrifugal dust collecting bucket 6. The conveying pipe 7 is also a well-sealed pipe. One end of the conveying pipe 7 is connected to the centrifugal dust collecting bucket 6, and the other end is connected to the outer wall of the filter bucket 9. The relatively clean air obtained after centrifugal separation in the centrifugal dust collecting bucket 6 will flow through the conveying pipe 7 and enter the filter bucket 9 again for the next round of filtration or subsequent discharge, thus forming a cyclic process of dust collection, separation and reprocessing, ensuring that the entire device can process dust more fully and efficiently.
[0050] The coordinated operation of the dust hopper 18, conveying pipe, and centrifugal dust collection barrel 6 achieves centralized dust collection and reprocessing, improving dust removal capacity, achieving cleaner exhaust air, and recycling air resources, offering energy-saving and environmental advantages. It also ensures stable operation and continuous purification of the device, contributing to maintaining workshop air quality. This solves the problem of dust scattering and accumulation in the filter barrel 9 and incomplete dust removal.
[0051] Please see the attached Figure 2 -Attached Figure 5 The side wall of the box body 1 is provided with a removal groove, and a dust box 14 is provided in the removal groove of the box body 1. The bottom end of the dust box 14 is provided inside the box body 1, and the upper surface of the dust box 14 is provided at the bottom end of the centrifugal dust collecting bucket 6. A dust box 13 is provided inside the dust box 14, and a handle 12 is provided on one side of the dust box 13.
[0052] Specifically, during the operation of the efficient dust collection device for woodworking machinery, the dust undergoes a series of collection and separation processes and is eventually collected in the dust box 14 for centralized storage.
[0053] The sidewalls of the housing 1 are purposely designed with a removal slot, sized and shaped to accommodate the dust box 14, allowing for smooth removal and insertion. The bottom of the dust box 14, located within the housing 1, receives dust separated and settled from the centrifugal dust collection bucket 6 above. After the centrifugal dust collection bucket 6 separates the dust from the air through the centrifugal force generated by its high-speed rotation, the dust then falls by gravity to the upper surface of the dust box 14 below it, and then into the interior of the dust box 14.
[0054] A dust box 13 is placed inside the dust box 14. The dust box 13 serves as a container for directly collecting dust. It fits within the interior of the dust box 14 and can be stably placed within the dust box 14. When dust falls from the centrifugal dust collection bucket 6 into the dust box 14, it further falls into the dust box 13 for collection and storage. A handle 12 is provided on one side of the dust box 13. The handle 12 is a structural component that facilitates the operator's grip. When it is necessary to clean the dust collected in the dust box 13, the operator can grasp the handle 12, apply a certain amount of external force, and smoothly pull the dust box 14 and the dust box 13 out of the housing 1 along the removal slot on the side wall of the housing 1. The operator then removes the dust box 13 from the dust box 14, discards the collected dust, and then returns the dust box 13 to the dust box 14 and pushes the dust box 14 back into the removal slot of the housing 1, allowing the entire device to continue normal operation and perform subsequent dust collection work.
[0055] By providing a dust box 14 with a dust box 13 and a corresponding removal structure, dust can be collected and cleaned centrally, which improves the maintenance convenience of the device, ensures workshop safety and hygiene, and is conducive to stable operation and extended service life of the device. The problems of difficult dust collection management and inconvenient cleaning operations are solved.
[0056] Please see the attached Figure 1 -Attached Figure 4 A centrifugal fan 4 is provided on the upper surface of the box body 1, a dust suction pipe 3 is fixedly provided at the input end of the centrifugal fan 4, a dust suction cover 2 is provided at one end of the dust suction pipe 3, a dust suction pipe 2 5 is fixedly provided at the output end of the centrifugal fan 4, one end of the dust suction pipe 2 5 is provided on the outer wall of the centrifugal dust collecting bucket 6, and a plurality of universal wheels 11 are provided at the bottom end of the box body 1.
[0057] Specifically, the input end of the centrifugal fan 4 is fixedly connected to the dust collection pipe 3, which serves as a channel for conveying dust-laden air, and one end of the dust collection hood 2 extends outward. The dust collection hood 2 is usually placed near the source of dust generated by the woodworking machinery. Its shape and opening size are designed according to the characteristics of the specific dust generation area, with the aim of covering the dust generation source over as large an area as possible so that the generated dust can smoothly enter the dust collection hood 2. When the woodworking machinery starts to operate and generate dust, after the centrifugal fan 4 starts to operate, its internal impeller rotates at high speed, thereby forming a negative pressure environment in the dust collection pipe 3 and the dust collection hood 2. Under the action of the external atmospheric pressure, the dust-laden air generated by the woodworking machinery will be continuously sucked into the dust collection hood 2 along the pressure difference, and then flow along the dust collection pipe 3 to the centrifugal fan 4.
[0058] The output end of centrifugal fan 4 is fixedly connected to dust collection pipe 2 5, which is also a well-sealed conveying pipe, one end of which is connected to centrifugal fan 4 and the other end is connected to the outer wall of centrifugal dust collection bucket 6. Dust-laden air flowing from dust collection pipe 1 3 into centrifugal fan 4 is accelerated and conveyed by centrifugal fan 4 before being transported along dust collection pipe 2 5 into centrifugal dust collection bucket 6. Once inside centrifugal dust collection bucket 6, the dust particles in the dust-laden air are flung toward the bucket wall by the powerful centrifugal force generated by its unique internal structure and high-speed rotation. Gradually, they settle to the bottom of the bucket under the action of gravity, achieving a preliminary separation of dust and air. The relatively clean air then continues to flow along the designed path of subsequent devices, participating in subsequent filtration and purification processes.
[0059] Furthermore, the bottom of the housing 1 is provided with a plurality of universal wheels 11, which are capable of flexible steering and rolling. Through a reasonable installation layout, the entire dust collection device can be easily moved on the workshop floor. Operators can easily change the placement of the device by pushing the device and utilizing the universal wheels 11, depending on the placement of the woodworking machinery within the workshop and actual operational needs, ensuring that the dust hood 2 is always in the appropriate position to effectively collect dust.
[0060] The centrifugal fan 4, dust collection pipe, dust collection hood 2, and universal wheels 11 achieve efficient dust collection, are flexible and easy to move, and ensure a smooth transition between initial dust separation and subsequent treatment. This improves overall dust treatment efficiency and air quality, enhances the device's applicability, and increases the service life of its components. This solves the problems of low dust collection efficiency and the inconvenience of fixing the device.
[0061] Please see the attached Figure 8 , an innovative purification process for efficient collection of woodworking machinery dust, used in a woodworking machinery efficient dust collection device, includes the following steps:
[0062] S1. Dust collection: The dust-laden air generated by the woodworking machine is sucked in by the centrifugal fan 4 on the upper surface of the box 1 through the dust collection pipe 1 3 and the dust collection hood 2. The dust-laden air enters the centrifugal dust collection bucket 6 through the dust collection pipe 2 5;
[0063] S2. Preliminary separation: In the centrifugal dust collection bucket 6, centrifugal force is used to preliminarily separate larger dust particles from the air. The separated large dust particles fall into the dust box 13 in the dust collection box 14 below. The preliminarily purified dust-laden air enters the filter bucket 9 through the conveying pipe 7;
[0064] S3, filtration by filter element 20: The dust-laden air entering the filter barrel 9 is further filtered by the filter element 20, intercepting fine dust on the surface and inside of the filter element 20, and the clean air is discharged through the exhaust pipe 16 on the upper surface of the filter barrel 9;
[0065] S4. Cleaning of the filter element 20: The cleaning mechanism and the driving mechanism work together to clean the filter element 20. The blower 8 delivers air to the rotating shaft 23 through the air duct 15 and the bearing 22. The motor 17 drives the rotating shaft 23 to rotate through the bevel gear 1 24 and the bevel gear 2 25. The rotating shaft 23 drives the relevant components to rotate. The bristles 1 28 on the brush plate 27 clean the inner wall of the filter element 20, and the bristles 2 32 on the brush plate 1 21 clean the outer wall of the filter element 20. At the same time, the air nozzle 1 29 and the air nozzle 2 31 continuously spray air to blow off the dust swept by the bristles in time. The blown dust falls into the centrifugal dust collecting bucket 6 through the dust collecting hopper 18 and the conveying pipe 2 10, and enters the dust box 13 for collection.
[0066] Specifically, in the innovative purification process for efficient collection of dust from woodworking machinery, dust collection is the primary link. The centrifugal fan 4 installed on the upper surface of the housing 1 plays a key role in driving the power. The centrifugal fan 4 contains key components such as an impeller. When the centrifugal fan 4 is started, its impeller starts to rotate at high speed, causing a negative pressure state to form in the center area of the impeller. One end of the dust collection pipe 3 is tightly and fixedly connected to the input end of the centrifugal fan 4, and the other end is connected to the dust collection hood 2, and the dust collection hood 2 is placed near the position where the woodworking machinery generates dust. Since the air pressure around the dust collection hood 2 is higher than that inside it (due to the negative pressure generated by the centrifugal fan 4), under the push of the external atmospheric pressure, the dust-laden air generated during the operation of the woodworking machinery follows the pressure difference, enters the dust collection pipe 3 through the dust collection hood 2, and is then continuously sucked into the centrifugal fan 4 along the dust collection pipe 3. Afterwards, the dust-laden air is transported by the centrifugal fan 4 through the dust suction pipe 5 connected to its output end and is transported to the centrifugal dust collecting bucket 6 to prepare for subsequent dust separation processing.
[0067] The dust-laden air entering the centrifugal dust collecting bucket 6 will be initially separated under the action of the centrifugal force generated by the specific structure inside the centrifugal dust collecting bucket 6 and the high-speed rotation. Factors such as the barrel shape, internal structure and rotation speed of the centrifugal dust collecting bucket 6 jointly determine the size and direction of the centrifugal force. After the dust-laden air enters, during the high-speed rotation process, due to the difference in mass between the dust particles and the air, the dust particles with relatively large mass are subjected to a greater centrifugal force and will be thrown toward the barrel wall of the centrifugal dust collecting bucket 6. After being thrown toward the barrel wall, these large dust particles gradually slide down along the barrel wall under the action of gravity, and eventually fall into the dust box 13 in the dust box 14 arranged below the centrifugal dust collecting bucket 6, achieving the initial separation of large dust particles from the air. After the initial separation, the air with relatively reduced dust content enters the filter barrel 9 through the conveying pipe 17 connected to the centrifugal dust collecting bucket 6, ready for the next step of deep filtration treatment.
[0068] When the dust-laden air enters the filter barrel 9 from the conveying pipe 7, it will fully contact the filter element 20. The filter element 20 is made of a material with a specific pore structure and filtering performance. The pore size can allow air molecules to pass through, but it can intercept fine dust particles. When the dust-laden air passes through the filter element 20, the fine dust particles will be intercepted on the surface and internal pores of the filter element 20 because they cannot pass through the pores of the filter element 20. The air can continue to flow smoothly through the filter element 20. The clean air after filtering will be discharged from the filter barrel 9 in an orderly manner along the channel formed by the exhaust pipe 16 inside the filter element 20 and the upper surface of the filter barrel 9, thereby completing the further filtration and purification of the dust-laden air, making the discharged air cleaner and reducing dust emissions.
[0069] During the continuous operation of the device, in order to prevent the filter element 20 from becoming clogged due to long-term dust interception, thereby affecting its filtering performance, a cleaning mechanism and a driving mechanism are provided to work together to clean the filter element 20. In terms of the cleaning mechanism, the support seat 19 is firmly mounted on the upper surface of the filter barrel 9. When the blower 8 placed thereon is started, an airflow with a certain pressure and flow rate is generated. The airflow is transmitted along the air duct 15 connected to the output end of the blower 8, and enters the interior of the rotating shaft 23 through the bearing 22 set at the top of the rotating shaft 23, providing an air source for subsequent cleaning operations. In terms of the driving mechanism, the motor 17 is mounted at a specific position on the upper surface of the filter barrel 9. After the motor 17 is started, the bevel gear 1 24 fixed at its output end begins to rotate. The bevel gear 1 24 and the bevel gear 2 25 are connected by meshing between the teeth to achieve power transmission. Since the bevel gear 2 25 is fixed on the outer wall of the rotating shaft 23, the rotation of the bevel gear 1 24 drives the bevel gear 2 25 to rotate, and then drives the rotating shaft 23 to rotate around its axis. As the rotating shaft 23 rotates, the connecting pipe 1 26 and connecting pipe 2 30 on its outer wall also rotate, thereby driving the synchronous rotation of brush plate 2 27 at one end of connecting pipe 1 26 and brush plate 1 21 at one end of connecting pipe 2 30. During the rotation process, the bristles 1 28 on one side of brush plate 27 come into close contact with the inner wall of the filter element 20. The friction between the bristles and the inner wall of the filter element 20 cleans the dust adhering to the inner wall of the filter element 20. At the same time, the air nozzle 1 29 on both ends of the brush plate 27 also moves with the rotation of the brush plate 27. After the airflow from the blower 8 passes through the rotating shaft 23 and connecting pipe 1 26 and reaches the air nozzle 1 29, the air nozzle 1 29 sprays air toward the inner wall of the filter element 20, blowing off the dust swept by the bristles 1 28. Similarly, the bristles 2 32 on the side wall of brush plate 1 21 clean the outer wall of filter element 20. The air nozzles 2 31 at both ends of the side wall of brush plate 1 21 rotate to spray the airflow from blower 8 toward the outer wall of filter element 20, blowing off the dust swept by the bristles 2 32. The blown-off dust is collected by the dust hopper 18 at the bottom of the filter barrel 9 under the guidance of gravity and the airflow within the device. It then flows down conveying pipe 2 10 and falls back into the centrifugal dust collection barrel 6, and finally enters the dust box 13 for collection, effectively cleaning the filter element 20 and ensuring that the filter element 20 can continue to perform its filtering function stably.
[0070] Through multi-step coordinated operation, comprehensive and efficient dust collection and purification are achieved, ensuring the long-term and stable operation of the filter element 20. It also ensures stable operation and easy maintenance of the entire device, effectively improving workshop air quality, reducing environmental pollution risks, lowering maintenance costs, and increasing device practicality. This solves the problems of incomplete dust collection and purification and inconvenient maintenance operations.
