Description

Technical Field

[0001] This invention relates to the field of cyclone separator technology, specifically to an energy-saving integrated fine powder separation device. Background Technology

[0002] Fine powder separation is a process that separates powdery materials from gas. This process is widely used in many industrial fields, including food processing, chemical industry, pharmaceutical industry, mining, and building materials. Common fine powder separation methods separate powdery materials by passing them through sieves or sieve openings. Different sized particles are separated by the size of the sieve openings. Larger particles are trapped on the sieve, while smaller particles pass through. However, sieving is usually used for the primary classification of particles. Air separation is a method that separates particles according to their weight and size. Particles move in an airflow. Larger and heavier particles settle down, while smaller and lighter particles are carried away by the airflow. This method is often used for the fine classification of fine powders. Centrifugal separation uses rotational force to separate particles. When the material is placed in a rotating container, heavier particles move outward, while lighter particles move inward. This method can be used to separate fine powders from powdered materials. Other separation methods include electromagnetic separation, liquid separation, gravity separation, etc. Different fine powder separation methods are suitable for different materials and separation requirements. Choosing the right method usually involves considering factors such as particle size, density, shape, humidity, and required separation accuracy. Choosing the right separation method can help improve production efficiency and product quality.

[0003] Existing cyclone centrifuges often overlook the impact of air humidity on the separation of fine powders. The airflow of fine powder contains water vapor, which, after a long period of cyclone separation, combines with the fine powder and adheres to the inner wall of the rotating inner sleeve. Over time, this water vapor accumulates and thickens, causing the powder to stick and clump together, preventing the airflow from rotating and generating sufficient centrifugal force, thus affecting the separation of fine powders. Summary of the Invention

[0004] The purpose of this invention is to provide an energy-saving integrated fine powder separation device to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an energy-saving integrated fine powder separation device, including a support frame and a centrifugal air pump. The separation device includes a separator shell, a rotating inner sleeve, an inner tube, and a feeding box. The separator shell is mounted on the support frame, and an air inlet is tangentially arranged at the upper part of the separator shell. The rotating inner sleeve is rotatably disposed inside the separator shell, and the inner tube is disposed in the middle of the separator shell. The feeding box is located at the bottom of the separator shell, and the centrifugal air pump is located at the top of the separator shell. The feeding box and the bottom of the separator shell are connected. The inner tube is connected to the top of the centrifugal air pump. When the fine powder is separated, the centrifugal air pump is powered on. The airflow carrying the powder enters the separator shell from the air inlet. The airflow rotates inside the separator shell. Under the action of centrifugal force, the powder comes into contact with the rotating inner tube. The fine powder is decelerated by friction and eventually moves downward with the overall trend of the airflow. Under the action of gravity, it falls into the feed box. The airflow will still carry a small amount of fine powder through the inner tube to the centrifugal air pump. Finally, the airflow enters the air outlet chamber through the air guide pipe and is discharged from the air outlet chamber.

[0006] Furthermore, the upper parts of the separator shell and the rotating inner sleeve are both cylindrical, while the lower parts of the separator shell and the rotating inner sleeve are both inverted conical. The separation device also includes a drive shaft, a discharge roller, and an air outlet chamber. The drive shaft passes through the feeding box and is rotatably connected to the feeding box. The discharge roller is mounted on the drive shaft and is located inside the feeding box. Several sealing plates are mounted on the discharge roller, which, along with the sealing plates, seals the feeding box. When airflow passes through the air outlet chamber, it drives the drive shaft to rotate via a pneumatic mechanism. As the drive shaft rotates, it drives the discharge roller to rotate. The space between every two adjacent sealing plates is continuously filled with fine powder. The interior of the feeding box cannot connect to the bottom due to the obstruction of the sealing plates. The fine powder can only be conveyed to the bottom by the rotation of the discharge roller using the space between the sealing plates. The fine powder falls under the action of gravity. The discharge roller and the sealing plates seal the feeding box and discharge the separated fine powder.

[0007] Furthermore, the air outlet chamber is located on one side of the feeding box. The air outlet chamber is provided with an air inlet and an air outlet. An air guide pipe is connected between the air inlet and the air outlet end of the centrifugal air pump. A pneumatic mechanism is provided inside the air outlet chamber, and the pneumatic mechanism is connected to the drive shaft.

[0008] Furthermore, the pneumatic mechanism includes a sun gear, a planetary carrier, and an internal gear ring. The drive shaft extends into the interior of the air outlet chamber and is connected to the sun gear. The planetary carrier is located on the outer ring of the sun gear and is installed inside the air outlet chamber. Several planetary gears are evenly distributed on the planetary carrier in a circle, and all of the planetary gears mesh with the sun gear. The internal gear ring meshes with the several planetary gears, and several blades are provided on the outer contour of the internal gear ring. The airflow flowing into the air outlet chamber impacts the blades, causing the internal gear ring to rotate. The planetary carrier is fixed, and the sun gear rotates through the transmission of the planetary gears. The sun gear rotates at a low speed, and the deceleration transmission increases the torque of the sun gear. The sun gear drives the drive shaft to rotate, that is, the first bevel gear and the second bevel gear rotate simultaneously.

[0009] Furthermore, a first bevel gear is installed on the drive shaft between the air outlet chamber and the discharge roller, and a second bevel gear is connected to the side of the drive shaft away from the air outlet chamber. Both the first bevel gear and the second bevel gear are located outside the discharge box.

[0010] Furthermore, a rotating shaft is rotatably mounted on the outside of the separator housing. A linkage bevel gear is mounted at the bottom of the shaft, and a pinion is mounted at the top. The linkage bevel gear meshes with a second bevel gear. A through groove is formed on the separator housing, and a toothed groove is formed at the position of the rotating inner sleeve corresponding to the through groove. The pinion meshes with the toothed groove. A scraper is also provided inside the separator housing. The scraper contacts the inner wall of the rotating inner sleeve. The airflow containing fine powder contains moisture. After a long period of cyclone separation, the moisture combines with the fine powder and adheres to the inner wall of the rotating inner sleeve. Over time, it accumulates and thickens. The second bevel gear drives the linkage bevel gear to rotate, and the linkage bevel gear drives the pinion to rotate through the rotating shaft. The pinion drives the rotating inner sleeve to rotate slowly through the toothed groove. The scraper scrapes off the fine powder adhering to the inner wall of the rotating inner sleeve, preventing the fine powder from sticking and clumping due to excessive moisture in the airflow. This prevents the airflow from being unable to rotate due to clumping.

[0011] Furthermore, a discharge shaft is rotatably mounted inside the inner tube. A driven bevel gear is provided at the bottom of the discharge shaft, which meshes with a first bevel gear. Two arc-shaped positive electrode plates are symmetrically embedded inside the inner tube. The discharge shaft and the positive electrode plates are connected to a control system via an electrical circuit. When the airflow carries a small amount of fine powder through the inner tube, the control system energizes the discharge shaft and the positive electrode plates, forming a discharge zone inside the inner tube. An electric field is generated between the discharge shaft and the positive electrode plates, and the fine powder in the airflow is eventually adsorbed onto the positive electrode plates. This secondary adsorption of the fine powder in the airflow prevents it from entering the centrifugal pump and prevents the fine powder in the airflow from leaking out of the separator shell, ensuring that the fine powder is separated cleanly.

[0012] Furthermore, a pair of dust discharge grooves are provided in the inner wall of the inner tube. The top of the pair of dust discharge grooves is lower than the top end face of the inner tube. A narrow slit is provided between each dust discharge groove and the inside of the inner tube. A gate is slidably installed inside the inner tube at the position corresponding to each narrow slit. A spring is provided between the gate and the inside of the inner tube. The gate seals the narrow slit.

[0013] Furthermore, each of the gate plates is equipped with an elastic baffle, and a scraper is installed on the discharge shaft. The scraper contacts the positive electrode plate. The first bevel gear drives the driven bevel gear to rotate, and the driven bevel gear drives the discharge shaft to rotate. The scraper installed on the discharge shaft is driven to rotate synchronously. When the scraper rotates, it scrapes off the fine powder adsorbed on the positive electrode plate. When the scraper contacts the elastic baffle on the gate plate, the scraper pushes the gate plate to open the narrow slit. The fine powder scraped off by the scraper is pushed into the dust discharge trough. The fine powder falls into the feed box along the dust discharge trough. As the discharge shaft continues to drive the scraper to rotate, the gate plate is pushed to the limit position and can no longer move. The elastic baffle begins to bend and deform until the scraper has completely scraped past the elastic baffle. Then, the gate plate is reset under the action of the spring, blocking the narrow slit and preventing the airflow from blowing the fine powder in the dust discharge trough. Through the cooperation of the scraper and the gate plate, the positive electrode plate is cleaned in a cyclic manner, enhancing the adsorption capacity of the positive electrode plate for fine powder and ensuring that the fine powder is cleaned thoroughly.

[0014] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0015] 1. After a long period of cyclone separation, water vapor will combine with fine powder and adhere to the inner wall of the rotating inner sleeve. Over time, it will accumulate and thicken. The second bevel gear drives the linkage bevel gear to rotate, and the linkage bevel gear drives the small gear to rotate through the rotating shaft. The small gear drives the rotating inner sleeve to rotate slowly through the tooth groove. The scraper scrapes off the fine powder adhering to the inner wall of the rotating inner sleeve, avoiding the phenomenon of fine powder sticking and clumping due to excessive moisture in the airflow. This prevents the airflow from being affected by clumping and unable to rotate.

[0016] 2. When the airflow carries a small amount of fine powder through the inner tube, the control system energizes the discharge shaft and the positive plate, forming a discharge zone inside the inner tube. An electric field is generated between the discharge shaft and the positive plate, and the fine powder in the airflow is eventually adsorbed onto the positive plate. This secondary adsorption of the fine powder in the airflow prevents it from entering the centrifugal pump and prevents it from leaking out of the separator shell, ensuring that the fine powder is separated cleanly.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figures 1-7This invention provides a technical solution: an energy-saving integrated fine powder separation device, including a support frame and a centrifugal air pump 5. The separation device includes a separator shell 1, a rotating inner sleeve 2, an inner tube 3, and a feed box 4. The separator shell 1 is mounted on the support frame. The upper parts of both the separator shell 1 and the rotating inner sleeve 2 are cylindrical, while the lower parts of both are inverted conical. An air inlet is tangentially arranged on the upper part of the separator shell 1. The rotating inner sleeve 2 is rotatably disposed inside the separator shell 1. The inner tube 3 is disposed in the middle of the separator shell 1. The feed box 4 is located at the bottom of the separator shell 1, and the centrifugal air pump 5 is located at the top of the separator shell 1. The feed box 4 is connected to the bottom of the separator shell 1, and the top of the inner tube 3 is connected to the suction end of the centrifugal air pump 5. When the fine powder is separated, the centrifugal air pump 5 is powered on and the airflow carrying the powder enters the interior of the separator shell 1 from the air inlet. The airflow rotates inside the separator shell 1. Under the action of centrifugal force, the powder comes into contact with the rotating inner sleeve 2. The fine powder is decelerated by friction and eventually moves downward with the overall trend of the airflow. Under the action of gravity, it falls into the feed box 4. The airflow carries a small amount of fine powder through the inner tube 3 to the centrifugal air pump 5. Finally, the airflow enters the air outlet chamber 19 from the air guide pipe 23 and is finally discharged from the air outlet chamber 19.

[0028] The separation device also includes a drive shaft 12, a discharge roller 10, and an air outlet chamber 19. The drive shaft 12 passes through the feeding box 4 and is rotatably connected to the feeding box 4. The discharge roller 10 is mounted on the drive shaft 12 and is located inside the feeding box 4. Several sealing plates 11 are provided on the discharge roller 10, which, together with the sealing plates 11, seals the feeding box 4. The air outlet chamber 19 is located on one side of the feeding box 4 and has an air inlet and an air outlet. An air guide pipe 23 connects the air inlet to the air outlet of the centrifugal air pump 5. A pneumatic motor is installed inside the air outlet chamber 19. The structure includes a pneumatic mechanism connected to the drive shaft 12. When airflow passes through the air outlet chamber 19, it drives the drive shaft 12 to rotate via the pneumatic mechanism. When the drive shaft 12 rotates, it drives the discharge roller 10 to rotate. The space between every two adjacent sealing plates 11 is continuously filled with fine powder. The interior of the discharge box 4 cannot connect with the bottom due to the obstruction of the sealing plates 11. It can only rely on the rotation of the discharge roller 10 to use the space between the sealing plates 11 to transfer the fine powder to the bottom. The fine powder falls under the action of gravity. The discharge box 4 is sealed by the discharge roller 10 and the sealing plates 11, and the fine powder is separated and discharged.

[0029] The pneumatic mechanism includes a sun gear 20, a planet carrier 21, and an internal gear ring 22. The drive shaft 12 extends into the interior of the air outlet chamber 19 and is connected to the sun gear 20. The planet carrier 21 is located on the outer ring of the sun gear 20 and is installed inside the air outlet chamber 19. Several planetary gears are evenly distributed on the planet carrier 21 in a circle, and all of the planetary gears mesh with the sun gear 20. The internal gear ring 22 meshes with several planetary gears. Several blades are provided on the outer contour of the internal gear ring 22. The airflow flowing into the air outlet chamber 19 impacts the blades and drives the internal gear ring 22 to rotate. The planet carrier 21 is fixed, and the sun gear 20 rotates through the transmission of the planetary gears. The sun gear 20 rotates at a low speed, and the sun gear 20 obtains increased torque through the deceleration transmission. The sun gear 20 drives the drive shaft 12 to rotate, that is, the first bevel gear 17 and the second bevel gear 18 rotate simultaneously.

[0030] A first bevel gear 17 is installed on the drive shaft 12 between the air outlet chamber 19 and the discharge roller 10. A second bevel gear 18 is connected to the side of the drive shaft 12 away from the air outlet chamber 19. Both the first bevel gear 17 and the second bevel gear 18 are located outside the feed box 4. A rotating shaft 13 is rotatably mounted on the outside of the separator housing 1. A linkage bevel gear 15 is installed at the bottom of the rotating shaft 13, and a pinion 14 is installed at the top of the rotating shaft 13. The linkage bevel gear 15 meshes with the second bevel gear 18. A through groove is opened on the separator housing 1. A toothed groove is opened at the position of the rotating inner sleeve 2 corresponding to the through groove. The pinion 14 meshes with the toothed groove. The interior is also equipped with a scraper 6, which contacts the inner wall of the rotating inner sleeve 2. The airflow of fine powder contains moisture. After a long period of cyclone separation, the moisture will combine with the fine powder and adhere to the inner wall of the rotating inner sleeve 2. Over time, it will accumulate and thicken. The second bevel gear 18 drives the linkage bevel gear 15 to rotate. The linkage bevel gear 15 then drives the pinion 14 to rotate through the rotating shaft 13. The pinion 14 drives the rotating inner sleeve 2 to rotate slowly through the tooth groove. The scraper 6 scrapes off the fine powder adhering to the inner wall of the rotating inner sleeve 2, avoiding the phenomenon of fine powder sticking and clumping due to excessive moisture in the airflow. This prevents the airflow from being affected by clumping and unable to rotate.

[0031] A discharge shaft 9 is rotatably mounted inside the inner tube 3. A driven bevel gear 16 is located at the bottom of the discharge shaft 9, and the driven bevel gear 16 meshes with a first bevel gear 17. Two arc-shaped positive electrode plates 24 are symmetrically embedded inside the inner tube 3. The discharge shaft 9 and the positive electrode plates 24 are connected to a control system via an electrical circuit. A pair of dust discharge grooves are formed in the inner wall of the inner tube 3. The top of the pair of dust discharge grooves is lower than the top end face of the inner tube 3. A narrow slit is formed between each dust discharge groove and the interior of the inner tube 3. A gate plate 7 is slidably mounted inside the inner tube 3 at the position corresponding to each narrow slit. A gap is formed between the gate plate 7 and the interior of the inner tube 3. A spring is used to seal the narrow gap with a gate 7. Each gate 7 is equipped with an elastic baffle. A scraper 8 is installed on the discharge shaft 9. The scraper 8 is in contact with the positive electrode plate 24. When the airflow carries a small amount of fine powder through the inner tube 3, the control system energizes the discharge shaft 9 and the positive electrode plate 24. A discharge zone is formed inside the inner tube 3. An electric field is generated between the discharge shaft 9 and the positive electrode plate 24. The fine powder in the airflow is eventually adsorbed onto the positive electrode plate 24. The fine powder in the airflow is adsorbed a second time, preventing the fine powder from entering the centrifugal pump 5 and preventing the fine powder in the airflow from leaking out of the separator shell 1, thus ensuring that the fine powder is separated cleanly.

[0032] The first bevel gear 17 drives the driven bevel gear 16 to rotate, and the driven bevel gear 16 drives the discharge shaft 9 to rotate. The scraper 8 installed on the discharge shaft 9 is driven to rotate synchronously. When the scraper 8 rotates, it scrapes off the fine powder adsorbed on the positive electrode plate 24. When the scraper 8 contacts the elastic baffle on the gate plate 7, the scraper 8 pushes the gate plate 7 to open the narrow gap. The fine powder scraped off by the scraper 8 is pushed into the dust discharge trough. The fine powder falls into the feed box 4 along the dust discharge trough. As the discharge shaft 9 continues to drive the scraper 8 to rotate, the gate plate 7 is pushed to the limit position and can no longer move. The elastic baffle begins to bend and deform until the scraper 8 has completely scraped past the elastic baffle. Then, the gate plate 7 is reset under the action of the spring, blocking the narrow gap and preventing the airflow from blowing the fine powder in the dust discharge trough. Through the cooperation of the scraper 8 and the gate plate 7, the positive electrode plate 24 is cleaned in a cyclic manner, which enhances the adsorption capacity of the positive electrode plate 24 for fine powder and ensures that the fine powder is cleaned.

[0033] The working principle of this invention is as follows: During fine powder separation, the centrifugal pump 5 is powered on, and the airflow carrying the powder enters the separator housing 1 through the air inlet. The airflow rotates inside the separator housing 1, and the powder comes into contact with the rotating inner sleeve 2 under the action of centrifugal force. The fine powder is decelerated by friction and eventually moves downward with the overall trend of the airflow, falling into the feed box 4 under the action of gravity. The airflow carrying a small amount of fine powder reaches the centrifugal pump 5 through the inner pipe 3. Finally, the airflow enters the outlet chamber 19 through the air guide pipe 23 and finally exits from the outlet chamber 19. When air flows through the air outlet chamber 19, it drives the drive shaft 12 to rotate via a pneumatic mechanism. When the drive shaft 12 rotates, it drives the discharge roller 10 to rotate. The space between every two adjacent sealing plates 11 is continuously filled with fine powder. The interior of the discharge box 4 cannot connect with the bottom due to the obstruction of the sealing plates 11. It can only rely on the rotation of the discharge roller 10 to use the space between the sealing plates 11 to transfer the fine powder to the bottom. The fine powder falls under the action of gravity. The discharge box 4 is sealed by the discharge roller 10 and the sealing plates 11, and the fine powder is separated and discharged.

[0034] The airflow flowing into the exhaust chamber 19 impacts the blades, causing the internal gear ring 22 to rotate. The planetary carrier 21 is fixed, and the sun gear 20 rotates through the transmission of the planetary gears. The sun gear 20 rotates at a low speed, and the reduction transmission makes the sun gear 20 obtain increased torque. The sun gear 20 drives the transmission shaft 12 to rotate, that is, the first bevel gear 17 and the second bevel gear 18 rotate simultaneously. The airflow containing fine powder contains water vapor. After a long period of cyclone separation, the water vapor will combine with the fine powder and adhere to the inner wall of the rotating inner sleeve 2. Over time, it will accumulate and thicken. The second bevel gear 18 drives the linkage bevel gear 15 to rotate. The linkage bevel gear 15 then drives the pinion 14 to rotate through the rotating shaft 13. The pinion 14 drives the rotating inner sleeve 2 to rotate slowly through the tooth groove. The scraper 6 scrapes off the fine powder adhering to the inner wall of the rotating inner sleeve 2, avoiding the phenomenon of fine powder sticking and clumping due to excessive moisture in the airflow. This plays a role in preventing the airflow from being unable to rotate due to clumping.

[0035] When the airflow carries a small amount of fine powder through the inner tube 3, the control system energizes the discharge shaft 9 and the positive electrode plate 24, forming a discharge zone inside the inner tube 3. An electric field is generated between the discharge shaft 9 and the positive electrode plate 24, and the fine powder in the airflow is eventually adsorbed onto the positive electrode plate 24. This secondary adsorption of the fine powder in the airflow prevents it from entering the centrifugal pump 5 and prevents the fine powder in the airflow from leaking out of the separator shell 1, ensuring that the fine powder is separated cleanly.

[0036] The first bevel gear 17 drives the driven bevel gear 16 to rotate, and the driven bevel gear 16 drives the discharge shaft 9 to rotate. The scraper 8 installed on the discharge shaft 9 is driven to rotate synchronously. When the scraper 8 rotates, it scrapes off the fine powder adsorbed on the positive electrode plate 24. When the scraper 8 contacts the elastic baffle on the gate plate 7, the scraper 8 pushes the gate plate 7 to open the narrow gap. The fine powder scraped off by the scraper 8 is pushed into the dust discharge trough. The fine powder falls into the feed box 4 along the dust discharge trough. As the discharge shaft 9 continues to drive the scraper 8 to rotate, the gate plate 7 is pushed to the limit position and can no longer move. The elastic baffle begins to bend and deform until the scraper 8 has completely scraped past the elastic baffle. Then, the gate plate 7 is reset under the action of the spring, blocking the narrow gap and preventing the airflow from blowing the fine powder in the dust discharge trough. Through the cooperation of the scraper 8 and the gate plate 7, the positive electrode plate 24 is cleaned in a cyclic manner, which enhances the adsorption capacity of the positive electrode plate 24 for fine powder and ensures that the fine powder is cleaned.
