Description

Technical Field

[0001] This invention relates to the field of wood dust removal technology, and more particularly to a dust removal device for wood industrial processing. Background Technology

[0002] The wood processing process generates a large amount of dust, which not only severely pollutes the production environment but also poses a significant threat to workers' health. Long-term exposure to high concentrations of wood dust can easily lead to occupational diseases such as respiratory illnesses and pneumoconiosis. Wood factories primarily use baghouse dust collectors to handle dust, relying on the filtration effect of the bags to intercept airborne dust. This method has a good dust removal effect within a certain range. However, during use, baghouse dust collectors suffer from low filtration efficiency and uneven distribution of dust-laden air. Distributed on the outside of the filter bags, the bags only perform dust removal locally, resulting in low bag utilization and reduced dust removal efficiency. Secondly, during dust removal, the varying sizes of dust particles in the air can easily damage the filter bags, necessitating regular replacement and leading to high maintenance costs. Furthermore, it is impossible to classify dust particles by size. Additionally, a separate pulse jet cleaning system is required for cleaning, which periodically blows air backwards through the filter bags. However, the cleaned filter bags cannot continue to be used for dust removal, compromising the efficiency of filter bag dust removal during cleaning. Summary of the Invention

[0003] The purpose of this invention is to solve the problems in the background art by proposing a dust removal device for wood processing.

The air inlet pipe is connected to the interior of the cavity, and the inner wall of the air inlet pipe is tangent to the inner wall of the cavity. The air outlet pipe is connected to the interior of a first air duct, and the inner wall of the air outlet pipe is tangent to the inner wall of the first air duct. A first dust discharge pipe is fixedly connected to the bottom of the cavity.

[0006] In the aforementioned dust removal equipment for wood processing, a second dust discharge pipe is fixedly connected to the side wall of the cavity, a dust collection tray is integrally formed on the top of the second dust discharge pipe, a dust discharge tray is integrally formed on the bottom of the first air duct, the dust collection tray is located below the dust discharge tray, and a third dust discharge pipe is fixedly connected to the bottom of the support cover, the third dust discharge pipe being slidably installed inside the second dust discharge pipe.

[0007] In the aforementioned dust removal equipment for wood processing, blade one and blade two are welded to the inner side of the exhaust duct. Blade one is located outside blade two and is located between the cavity and the exhaust duct one. Blade two is located between the exhaust duct one and the filter bag.

[0008] In the aforementioned dust removal equipment for wood processing, a slide and a first slide are movably mounted on the outer side of the rotating shaft. The first slide is located above the slide. A second slide is integrally formed on the side wall of the first slide. A ball bearing is integrally formed inside the second slide. A rotating rod is rotatably mounted on the top of the partition. The second slide is movably mounted on the outer side of the rotating rod. A corrugated groove is formed on the outer peripheral wall of the rotating rod. The ball bearing is slidably mounted inside the corrugated groove.

[0009] In the aforementioned dust removal equipment for wood processing, a motor is fixedly installed on the side wall of the cavity, a gear is fixedly connected to the output shaft of the motor, a gear ring is fixedly installed on the outer side of the exhaust duct, the gear and the gear ring mesh with each other, and a speed reduction assembly is provided between the rotating rod and the top block.

[0010] In the aforementioned dust removal equipment for wood processing, the side wall of the support cylinder is integrally formed with a sliding rod, the sliding rod is slidably inserted into the side wall of the sliding frame, a second spring is provided between the sliding frame and the side wall of the support cylinder, the side wall of the sliding frame is provided with an inclined surface, and the side wall of the sliding frame is integrally formed with a top block, the inclined surface and the top block abut against each other.

[0011] In the above-mentioned dust removal equipment for wood processing, a cavity cover is fixedly installed on the top of the cavity, and a second motor is fixedly installed inside the cavity cover. The output shaft and the rotating shaft of the second motor are fixedly connected. A sliding groove is provided on the outer peripheral wall of the rotating shaft. A spring top block is slidably installed inside the sliding groove. A locking groove is provided on the inner wall of the support cylinder, and the spring top block is slidably inserted into the locking groove.

[0012] Compared with existing technologies, the advantages of this invention are: 1. The dust removal components installed inside the cavity allow for cyclone dust removal of dust-laden air within the cavity, followed by baghouse dust removal. This combination of two dust removal methods enables the dust to be classified and treated, while simultaneously improving the dust removal efficiency. During the dust removal process, the duct rotates, and the blades accelerate and guide the rotating air between the cavity and the duct downwards, increasing the centrifugal force of the air rotation and improving the efficiency of the cyclone dust removal. The blades also drive the air entering the duct to rotate and be guided upwards, ensuring that the air inside the duct is evenly distributed on the outside of the bags, thus increasing the usable area of ​​the bags and the dust removal efficiency during the dust removal process.

[0013] 2. The dust collection components installed inside the filter bag cause the rotating shaft to drive the support cylinder to rotate during the dust removal process. This causes the two cloth sheets to rotate inside the filter bag. The rotation of the cloth sheets guides the air inside the filter bag to rotate and be discharged, increasing the amount of air passing through the filter bag and improving the dust removal efficiency. At the same time, as the cloth sheets guide the air inside the filter bag, the air continuously passes through the cloth sheets, allowing the cloth sheets to further treat the air for dust removal, further improving the dust removal effect and ensuring that the discharged air does not fail to meet the standards.

[0014] 3. By designing the blades and the cloth sheet to be tilted in opposite directions, the air duct and the rotating shaft rotate in opposite directions during the dust removal process of the cloth sheet. At this time, the blades provide air in the opposite direction to the rotation of the cloth sheet, so that the air passing through the bag directly impacts the cloth sheet, further improving the dust removal effect of the cloth sheet.

[0015] 4. Through the cooperation between the slide and the sliding frame, when the slide cylinder moves downward, the slide moves downward, the inclined surface abuts against the top block two, the sliding frame moves towards the cloth bag and abuts against the cloth bag, the bottom of the cloth bag moves upward, so that both the cloth sheet and the cloth bag vibrate once. At this time, the sliding frame and the top block one clamp the cloth bag, the top block one and the sliding frame drive the cloth sheet to reverse and twist the cloth bag, so that the dust shaken off the surface of the cloth sheet is discharged. At the same time, the bottom of the cloth bag moves further upward. When the slide cylinder one moves upward, the sliding frame and the slide return to their positions, the cloth bag returns to its position through the spring one, and vibrates again after returning to its position. Through the vibration of the cloth bag and the cloth sheet, the dust adsorbed on the outer surface of the cloth bag and the side wall of the cloth sheet falls off, reducing the number of times the cloth bag and cloth sheet are maintained. At the same time, it performs self-cleaning without stopping the machine, improving the dust removal efficiency. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0019] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0020] Reference Figure 1 - Figure 11 As shown, a dust removal device for wood processing includes a cavity 1. A dust blocking assembly is movably installed inside the cavity 1. The dust blocking assembly includes an exhaust duct 21 and a filter bag 22. A partition 221 and a support cover 222 are fixedly installed at the top and bottom of the filter bag 22, respectively. An exhaust duct 14 is fixedly installed inside the cavity 1. The partition 221 and the exhaust duct 14 are fixedly connected. The support cover 222 is slidably installed inside the exhaust duct 14. A spring 224 is provided between the support cover 222 and the exhaust duct 14. The exhaust duct 21 is rotatably installed inside the cavity 1. A support rod 214 is welded to the inner side of the exhaust duct 21. A top block 215 is integrally formed on the top of the support rod 214. The top block 215 is located between the exhaust duct 14 and the filter bag 22. The dust collection assembly is movably installed inside the bag 22. The dust collection assembly includes a support cylinder 321, two cloth pieces 32, and two sliding frames 322. A rotating shaft 31 is rotatably installed inside the air duct 14. The rotating shaft 31 is rotatably installed inside the support cylinder 321. The two cloth pieces 32 and the sliding frames 322 are evenly distributed on the outside of the support cylinder 321. The sliding frames 322 are slidably installed on the side wall of the support cylinder 321. The two ends of the cloth pieces 32 are fixedly connected to the support cylinder 321 and the sliding frames 322, respectively.

[0021] like Figure 1 , Figure 2 and Figure 5 As shown, an air inlet pipe 121 and an air outlet pipe 122 are fixedly connected to the side wall of the cavity 1. The air inlet pipe 121 is connected to the interior of the cavity 1, and the inner wall of the air inlet pipe 121 is tangent to the inner wall of the cavity 1. The air outlet pipe 122 is connected to the interior of the air duct 14, and the inner wall of the air outlet pipe 122 is tangent to the inner wall of the air duct 14. A dust exhaust pipe 123 is fixedly connected to the bottom of the cavity 1.

[0022] The air inlet pipe 121 is fixedly connected to the external fan, so that the air carrying dust enters the cavity 1 quickly through the air inlet pipe 121 and rotates along the inner wall of the cavity 1. At this time, the air carrying dust is subjected to cyclone dust removal inside the cavity 1. The air that has been cyclone dust removal enters the air duct 14. Large dust particles filtered out during the cyclone dust removal process are discharged through the dust discharge pipe 123 to avoid damage to the filter bag 22 caused by large dust particles.

[0023] like Figure 2 and Figure 5 As shown, a second dust discharge pipe 124 is fixedly connected to the side wall of cavity 1. A dust collection tray 125 is integrally formed on the top of the second dust discharge pipe 124. A dust discharge tray 141 is integrally formed on the bottom of the first air duct 14. The dust collection tray 125 is located below the dust discharge tray 141. A third dust discharge pipe 223 is fixedly connected to the bottom of the support cover 222. The third dust discharge pipe 223 is slidably installed inside the second dust discharge pipe 124.

[0024] The air entering the air duct 14 moves through the air passage between the dust discharge plate 141 and the dust collection plate 125 to the space between the air duct 14 and the filter bag 22. At this time, the air is dusted by the filter bag 22. The air after passing through the filter bag 22 is discharged through the exhaust pipe 122. The dust adsorbed on the surface of the filter bag 22 falls above the dust discharge plate 141 and the dust collection plate 125 and is discharged through the second dust discharge pipe 124.

[0025] Further reference Figure 2 , Figure 3 , Figure 9 and Figure 10To explain, the cloth sheet 32 ​​is inclined. During the dust removal process of the filter bag 22, the motor 311 drives the rotating shaft 31 to rotate, which in turn drives the support cylinder 321 to rotate, causing the two cloth sheets 32 to rotate inside the filter bag 22. At this time, the rotation of the cloth sheet 32 ​​guides the air inside the filter bag 22 to rotate and be discharged, increasing the amount of air passing through the filter bag 22 and improving the dust removal efficiency of the filter bag 22. At the same time, the direction of air rotation is the same as the direction tangent to the exhaust pipe 122 and the air duct 14, which speeds up the air discharge and further improves the dust removal efficiency of the filter bag 22. In addition, during the process of the cloth sheet 32 ​​guiding the air inside the filter bag 22 to move, the air continuously passes through the cloth sheet 32, allowing the cloth sheet 32 ​​to perform dust removal on the air again, further improving the dust removal effect and ensuring that the discharged air does not have any substandard problems.

[0026] like Figure 2 , Figure 4 , Figure 6 and Figure 7 As shown, blade 211 and blade 212 are welded to the inner side of the air duct 21. Blade 211 is located outside blade 212. Blade 211 is located between cavity 1 and air duct 14. Blade 212 is located between air duct 14 and bag 22. Motor 131 is fixedly installed on the side wall of cavity 1. Gear 132 is fixedly connected to the output shaft of motor 131. Gear ring 213 is fixedly installed on the outer side of air duct 21. Gear 132 and gear ring 213 mesh with each other.

[0027] Among them, the tilting direction of blade 211 is opposite to that of blade 212. During the cyclone dust removal and bag dust removal process, motor 131 drives the exhaust duct 21 to rotate through gear 132 and gear ring 213, so that blade 211 accelerates and guides the rotating air between cavity 1 and exhaust duct 14 downward, increasing the centrifugal force of the air rotation and improving the efficiency of cyclone dust removal. Blade 212 drives the air entering the exhaust duct 14 to rotate and guide it upward, so that the air inside the exhaust duct 14 is evenly distributed on the outside of the bag 22, improving the usable area and dust removal efficiency of the bag 22 during the dust removal process. The tilting direction of blade 212 is opposite to that of cloth 32, and the rotation direction of exhaust duct 21 and rotating shaft 31 is opposite. So that during the dust removal process of cloth 32, blade 212 provides air with the opposite swirling direction, so that the air passing through the bag 22 directly hits cloth 32, further improving the dust removal effect of cloth 32.

[0028] like Figure 3 , Figure 6 and Figure 11As shown, a slide 33 and a first slide cylinder 332 are movably mounted on the outer side of the rotating shaft 31. The first slide cylinder 332 is located above the slide 33. A second slide cylinder 333 is integrally formed on the side wall of the first slide cylinder 332. A ball bearing 334 is integrally formed inside the second slide cylinder 333. A rotating rod 34 is rotatably mounted on the top of the partition plate 221. The second slide cylinder 333 is movably mounted on the outer side of the rotating rod 34. A corrugated groove 348 is provided on the outer peripheral wall of the rotating rod 34. The ball bearing 334 is slidably mounted inside the corrugated groove 348. A speed reduction assembly is provided between the rotating rod 34 and the top block 215.

[0029] During the rotation of the air duct 21, the air duct 21 drives the top block 215 to rotate, so that the top block 215 continuously drives the rotating rod 34 to rotate through the deceleration assembly. Each time the rotating rod 34 rotates once, the rotating rod 34 drives the slide cylinder 333 to move up and down twice continuously through the corrugated groove 348 and the sliding ball 334.

[0030] Further reference Figure 2 , Figure 4 , Figure 6 and Figure 11 The deceleration assembly includes a rotating rod 341, a gear ring 342, and a roller 343. The rotating rod 341 is rotatably mounted on the inner wall of the air duct 14. The roller 343 is fixedly mounted on the bottom of the rotating rod 341 and abuts against the side wall of the top block 215. The gear ring 342 is rotatably mounted inside the air duct 14. An intermittent gear ring 344 is integrally formed on the top of the gear ring 342. A gear 346 is rotatably mounted on the top of the rotating rod 341. The intermittent gear ring 344 and the gear 346 mesh with each other. A gear 345 is fixedly mounted on the side wall of the rotating rod 341. 345 meshes with gear ring 2 342. Gear 4 347 is fixedly installed at the bottom of rotating rod 34. Gear 4 347 meshes with gear 3 346. During the rotation of the induced draft tube 21, when the side wall of top block 1 215 abuts against roller 343, top block 1 215 drives roller 343 to rotate one revolution. Gear 2 345 rotates one revolution and drives gear ring 2 342 to rotate. When intermittent gear ring 344 meshes with gear 3 346, intermittent gear ring 344 drives gear 4 347 to rotate one revolution through gear 3 346. At this time, rotating rod 34 rotates one revolution.

[0031] like Figure 2 , Figure 3 and Figure 9 As shown, a sliding rod 325 is integrally formed on the side wall of the support cylinder 321. The sliding rod 325 is slidably inserted into the side wall of the sliding frame 322. A spring 324 is provided between the side wall of the sliding frame 322 and the side wall of the support cylinder 321. An inclined surface 331 is provided on the side wall of the sliding frame 33. A top block 323 is integrally formed on the side wall of the sliding frame 322. The inclined surface 331 and the top block 323 abut against each other.

[0032] During the up-and-down movement of the second slide cylinder 333, the first slide cylinder 332 moves along with it. When the first slide cylinder 332 moves downwards with the second slide cylinder 333, it presses against and squeezes the slide frame 33, causing the slide frame 33 to move downwards and press against the top block 323 via the inclined surface 331. At this time, the sliding frame 322 moves towards the cloth bag 22 and presses against the cloth bag 22, causing the bottom of the cloth bag 22 to move upwards. At this time, the cloth piece 32 and the cloth bag 22... Each component vibrates once. When slide cylinder 1 332 moves upward with slide cylinder 2 333, slide frame 322 and slide frame 33 return to their original positions via spring 2 324, and bag 22 returns to its original position via spring 1 224. After returning to its original position, it vibrates again. Through the vibration of bag 22 and cloth sheet 32, the dust adsorbed on the outer surface of bag 22 and the side wall of cloth sheet 32 ​​falls off, reducing the number of maintenance times for bag 22 and cloth sheet 32. At the same time, it performs self-cleaning without stopping the machine, improving the efficiency of dust removal.

[0033] like Figure 2 , Figure 3 , Figure 6 and Figure 9 As shown, a cavity cover 11 is fixedly installed on the top of the cavity 1. A second motor 311 is fixedly installed inside the cavity cover 11. The output shaft of the second motor 311 is fixedly connected to the rotating shaft 31. A sliding groove 312 is provided on the outer peripheral wall of the rotating shaft 31. A spring top block 313 is slidably installed inside the sliding groove 312. A locking groove 326 is provided on the inner wall of the support cylinder 321. The spring top block 313 is slidably inserted into the locking groove 326.

[0034] During the process of the sliding frame 322 supporting the cloth bag 22, the sliding frame 322 and the cloth bag 22 abut against the side wall of the top block 215, so that the sliding frame 322 and the top block 215 clamp the cloth bag 22. At this time, the air duct 21 drives the cloth sheet 32 ​​to reverse through the top block 215 and the sliding frame 322, so that the dust shaken off the surface of the cloth sheet 32 ​​falls into the dust discharge pipe 223 and is discharged. At the same time, the top block 215 and the sliding frame 322 twist the cloth bag 22, so that the bottom of the cloth bag 22 moves further upward, increasing the vibration force when the cloth bag 22 returns to its position, and improving the self-cleaning effect of the cloth bag 22.

[0035] The working principle and usage of this invention are explained in detail below: The external fan, motor 131, and motor 311 are started. The external fan drives dust-laden air to quickly enter the cavity 1 through the air inlet pipe 121 and rotates along the inner wall of the cavity 1, causing the dust-laden air to undergo cyclone dust removal inside the cavity 1. The air that has undergone cyclone dust removal enters the air duct 14. Large dust particles filtered out during the cyclone dust removal process are discharged through the dust discharge pipe 123 to prevent damage to the filter bag 22. The air entering the air duct 14 moves through the air passage between the dust discharge plate 141 and the dust collection plate 125 to the space between the air duct 14 and the filter bag 22. Motor 131 drives the air duct 21 to... The rotation of the blades 211 accelerates and guides the air rotating between the cavity 1 and the duct 14 downwards, increasing the centrifugal force of the air rotation and improving the efficiency of cyclone dust removal. The blades 212 drive the air entering the duct 14 to rotate and guide it upwards, ensuring the air inside the duct 14 is evenly distributed on the outside of the filter bags 22, increasing the usable area and dust removal efficiency of the filter bags 22 during dust removal. The air passing through the filter bags 22 is discharged through the exhaust pipe 122. The dust adsorbed on the surface of the filter bags 22 falls above the dust discharge plate 141 and the dust collection plate 125, and is then discharged through the exhaust pipe 124. The motor 311 drives the rotating shaft 31 to rotate, which in turn drives the support cylinder 321 to rotate, causing the two cloth sheets 32 to rotate. The inner side of bag 22 rotates, and the rotation of cloth 32 guides the air inside bag 22 to rotate and be discharged, increasing the amount of air passing through bag 22 and improving the dust removal efficiency of bag 22. Simultaneously, the direction of air rotation is the same as the direction tangent to exhaust pipe 122 and air duct 14, accelerating the air discharge speed and further improving the dust removal efficiency of bag 22. Furthermore, during the process of cloth 32 guiding the air movement inside bag 22, the air continuously passes through cloth 32, allowing cloth 32 to further treat the air for dust removal, further improving the dust removal effect and ensuring that the discharged air meets standards. During the dust removal process of cloth 32, blade 212 provides air in the opposite direction of rotation, allowing the air passing through bag 22 to directly... The impact on the cloth sheet 32 ​​further enhances its dust removal effect. During the rotation of the exhaust duct 21, the exhaust duct 21 drives the top block 215 to rotate, causing the top block 215 to continuously drive the rotating rod 34 to rotate via the reduction gear assembly. When the rotating rod 34 rotates one revolution, it drives the sliding cylinder 333 to move up and down twice consecutively. The sliding cylinder 332 follows the sliding cylinder 333. When the sliding cylinder 332 moves downwards with the sliding cylinder 333, it drives the sliding frame 33 to move downwards. The inclined surface 331 abuts against the top block 323, and the sliding frame 322 moves towards the cloth bag 22 and abuts against the cloth bag 22. The bottom of the cloth bag 22 moves upwards, causing both the cloth sheet 32 ​​and the cloth bag 22 to vibrate once.At this time, the sliding frame 322 and the top block 215 clamp the cloth bag 22. The top block 215 and the sliding frame 322 drive the cloth sheet 32 ​​to reverse, causing the dust shaken off the surface of the cloth sheet 32 ​​to fall into the dust discharge pipe 223 and be discharged. When the first slide cylinder 332 moves upward with the second slide cylinder 333, the sliding frame 322 and the slide cylinder 33 return to their original positions via the second spring 324. The cloth bag 22 returns to its original position via the first spring 224 and vibrates again after returning to its original position. Through the vibration of the cloth bag 22 and the cloth sheet 32, This process causes dust adsorbed on the outer surface of the filter bag 22 and the sidewalls of the cloth sheet 32 ​​to fall off, reducing the frequency of maintenance for the filter bag 22 and cloth sheet 32. Simultaneously, it performs self-cleaning without stopping the machine, improving dust removal efficiency. Furthermore, during the reverse rotation of the cloth sheet 32 ​​driven by the top block 215 and the sliding frame 322, the top block 215 and the sliding frame 322 twist the filter bag 22, causing the bottom of the filter bag 22 to move further upward, increasing the vibration force when the filter bag 22 returns to its original position, and enhancing the self-cleaning effect of the filter bag 22.

[0036] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.

[0037] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. 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.
