Description

Technical Field

[0001] This invention relates to the field of sorting and dust removal equipment technology, specifically to a dust removal device for a sunflower seed sorting apparatus. Background Technology

[0002] In the process of sorting and processing sunflower seeds, in order to reduce solid waste pollution, dust removal equipment is often needed to remove dust from the sunflower seed sorting device. Patent application number CN202111542801.7 discloses a dust removal system and method. When transporting raw coal in the underground sorting system, the first atomizing component of the spray device sprays the raw coal on the underground sorting system to reduce dust. Then, the induced draft fan rotates to create negative pressure inside the box, and the flying dust enters the box from the dust collection hood through the air inlet and flows towards the air outlet. During this process, the second atomizing component of the spray device further sprays and reduces dust in the gas flow within the housing, forming dust-laden wastewater. Clean gas flows out from the outlet, while the dust-laden wastewater is filtered by the filter component and flows out from the drain into a water storage tank. The water in the storage tank can be recycled for use in the spray device. This dust removal system effectively collects coal mine dust, avoiding the danger of dust explosions. It also boasts high dust removal efficiency, strong applicability, and a simple structure. The invention patent with patent application number CN202111066502.0 discloses an intelligent ore separation... The dust removal device for the sorting machine involves the ore entering the sorting cylinder and then the sorting bin. The ore is sorted layer by layer by the bottom sorting mesh. The rotation of the drive shaft causes the sorting bin to rotate, and the ore moves towards the second sorting mesh due to centrifugal force. It then falls through the second mesh onto the bottom guide plate and flows out to the discharge port. Dust is then atomized and removed by dust removal nozzles at each layer. This method effectively sorts the ore and uses centrifugal force to expel the sorted ore. It is highly efficient and convenient. Based on the publicly available technical solution, existing sorting dust removal equipment... During use, on the one hand, dust removal can easily cause clogging of the filter mechanism, which is detrimental to ventilation efficiency and thus to the dust removal effect; on the other hand, cleaning the filter mechanism can easily cause significant wear and tear on the filter structure, which is detrimental to the safe operation of the filter structure; furthermore, when cleaning the filter structure, it is often only possible to remove dust from the surface of the filter structure, and some dust embedded in the filter pores of the filter structure is often not effectively removed, which is detrimental to the cleaning effect of the filter structure.

[0013] Furthermore, an annular tube is fitted on the outer side of the sleeve, and the bottom of the pump housing is connected to one side of the annular tube.

Both the bottom of the upper tube and the top of the lower tube are provided with blowing ports, which are located at the top and bottom of the screw plate, respectively.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In operation, the dust removal equipment of this sunflower seed sorting device involves pouring sunflower seeds into the hopper. The first discharge valve causes the seeds to fall onto the right side of the screen. The first motor, via a crankshaft and connecting rod, drives the screen to move back and forth along the inner side of the chute via pulleys. Smaller sunflower seeds fall onto the inclined plate on the right side of the screen and are then discharged through the outlet. Smaller seeds fall onto the guide plate through the screen and are discharged through outlet two. Larger seeds fall through the left end of the screen into outlet one and are discharged outwards. Dust and debris are drawn into the inner side of the air duct by the fan through the mesh of the screen, guide plate, and inclined plate. During the screening process, further debris falls into the cone hopper and is discharged outwards through the second discharge valve. After entering the air duct... The dust is filtered out by the filter cartridge and filter cover, preventing it from drifting outwards and avoiding solid waste pollution during the screening process. The second motor drives the screw plate to rotate, and the screw plate drives the filter cover and filter cartridge to rotate on the outer and inner rings through friction. This effectively scrapes the dust on the filter cover and filter cartridge into the inner side of the sleeve and the baffle through the gaps in the baffle. Then, the screw plate spirals and pushes the dust into the inner side of the sleeve until the dust is squeezed and compacted inside the sleeve. Then, the dust is pushed open by the screw plate and discharged from the left end of the sleeve. This allows for real-time cleaning of the filter cover and filter cartridge, preventing them from becoming clogged, ensuring ventilation efficiency, and thus effectively ensuring the absorption of dust generated inside the chamber.

[0015] 2. When the fan of this sunflower seed sorting device is working, it drives the impeller to rotate inside the pump casing. Utilizing the centrifugal force generated by the impeller, the filtered air inside the air duct is drawn in from both sides of the pump casing and then pumped to the inside of the ring pipe. The airflow is then pumped through the ring pipe to the inside of the upper and lower pipes. The lower pipe blows the airflow from the outside of the filter cover inward through the nozzle, while the upper pipe blows the airflow from the inside of the filter cartridge outward through the nozzle. This effectively utilizes the blowing force of the airflow and the scraping effect of the scraper sleeve to clean the filter cover and filter cartridge, reducing the adhesion of dust to the filter cartridge and filter cover. This effectively reduces the friction between the scraper sleeve and the filter cover and filter cartridge, thereby effectively reducing the wear of the filter cover and filter cartridge and ensuring their service life.

[0016] 3. When the dust removal equipment of this sunflower seed sorting device is in use, the airflow blows towards the filter cartridge and filter cover through the nozzles in the upper and lower pipes. This effectively blows away the fine dust particles that are blocked in the filter holes of the filter cartridge and filter cover. Due to the resistance of the filter cover and filter cartridge to the airflow, the dust removed is reduced from flying between the filter cartridge and filter cover. The suction force generated by the spiral push of the screw plate in the sleeve can suck the dust into the space between the scraper sleeve and the baffle sleeve, and then push it to the inside of the sleeve by the spiral push of the screw plate. This effectively prevents fine dust particles from clogging the inside of the filter holes of the filter cover and filter cartridge, effectively ensuring the cleaning effect of the filter cover and filter cartridge, and thus ensuring the dust removal effect of the filter cover and filter cartridge.

The bottom of the upper tube 36 is clamped to the inner wall of the bottom of the filter cartridge 23, and the top of the lower tube 37 is clamped to the outer side of the bottom of the filter cover 22. Both the bottom of the upper tube 36 and the top of the lower tube 37 have nozzles 38, located at the top and bottom of the screw plate 28, respectively. During use, when airflow passes through the nozzles 38 in the upper tube 36 and lower tube 37 and blows towards the filter cartridge 23 and the filter cover 22, it can... The system effectively blows away the fine dust particles clogging the filter holes of the filter cartridge 23 and filter cover 22. Due to the resistance of the filter cover 22 and filter cartridge 23 to the airflow, the dust particles are reduced from flying between the filter cartridge 23 and filter cover 22. The suction force generated by the spiral push of the screw plate 28 in the sleeve 29 can draw the dust into the space between the scraper sleeve 31 and the baffle sleeve 32, and then push it to the inside of the sleeve 29 by the spiral push of the screw plate 28. This effectively prevents fine dust particles from clogging the inside of the filter holes of the filter cover 22 and filter cartridge 23, effectively ensuring the cleaning effect of the filter cover 22 and filter cartridge 23, and thus ensuring the dust removal effect of the filter cover 22 and filter cartridge 23.

[0020] In this embodiment, the air duct 20 is bolted to one side of the housing 1, with one end of the air duct 20 extending into the inner side of the housing 1. The fan 21 is bolted to the inner wall of the other end of the air duct 20. The outer side of the outer ring 24 is bolted to the inner wall of one end of the air duct 20.

One end of the filter cylinder 23 has a filter screen integrally formed thereon, and the other end of the filter cylinder 23 is mounted to the inner wall of the inner ring 25 via a bearing. The inner ring 25 is fixed to the inner side of the air duct 20 by a support rod. The outer ring 24... A support block 26 is welded to the inner wall of the bottom. The second motor 27 is bolted to one side of the support block 26. A sleeve 29 is welded to one side of the inner ring 25. One end of the screw plate 28 is keyed to the output shaft of the second motor 27. The other end of the screw plate 28 passes through the inner ring 25 and extends to the inside of the sleeve 29. A hinged plate 30 is installed on the inner wall of one end of the sleeve 29. The top of the hinged plate 30 is mounted on the inner wall of the top of the sleeve 29 via a rotating shaft. The bottom of the hinged plate 30 is engaged with the inner wall of the bottom of the sleeve 29. The top of the screw plate 28 is engaged with the outer side of the bottom of the filter cartridge 23. The bottom of the screw plate 28 is engaged with the inner wall of the bottom of the filter cover 22. The scraper sleeve 31 and the baffle sleeve 32 are respectively secured to both sides of the screw plate 28. The two ends of the scraper sleeve 31 and the baffle sleeve 32 are respectively bolted to the support block 26 and the inner ring 25. The top and bottom of the scraper sleeve 31 are respectively secured to the outer side of the bottom of the filter cartridge 23 and the inner wall of the bottom of the filter cover 22. The distance between the baffle sleeve 32 and the filter cartridge 23 and the filter cover 22 gradually decreases towards the scraper sleeve 31. One end of the sleeve 29 passes through the air duct 20 and extends to the outside of the air duct 20. When the fan 21 is working, it drives the impeller 34 to rotate inside the pump casing 33. Utilizing the centrifugal force generated by the impeller 34, the filtered air inside the air duct 20 is forced through the two sides of the pump casing 33. The airflow is drawn into the inner side of the pump casing 33 and then pumped to the inner side of the ring pipe 35. The airflow is then pumped through the ring pipe 35 to the inner side of the upper pipe 36 and the lower pipe 37. The lower pipe 37 blows the airflow from the outside of the filter cover 22 inward through the nozzle 38, and the upper pipe 36 blows the airflow from the inside of the filter cartridge 23 outward through the nozzle 38. This effectively uses the blowing force of the airflow and the scraping effect of the scraper sleeve 31 to clean the filter cover 22 and the filter cartridge 23, reducing the adhesion of dust to the filter cartridge 23 and the filter cover 22. This also effectively reduces the friction between the scraper sleeve 31 and the filter cover 22 and the filter cartridge 23, thereby effectively reducing the wear of the filter cover 22 and the filter cartridge 23 and ensuring the service life of the filter cover 22 and the filter cartridge 23.

[0021] In this embodiment, the support plate 2 is welded to the bottom of the box body 1, the hopper 3 is bolted to the top of the box body 1, the discharge valve 4 is installed at the bottom of the hopper 3, and the hopper 3 is connected to the top of one side of the box body 1 through the discharge valve 4. The pulley 6 is bolted to the outer side of the screen 5, and a groove 7 is welded to the inner wall of the box body 1. The pulley 6 is engaged with the inner side of the groove 7. The side box 8 is bolted to the top of one side of the box body 1, and the motor 9 is bolted to the inner wall of the side box 8. A crankshaft 10 is bolted to the output shaft of the motor 9, and a connecting rod 11 is mounted on the crankshaft 10. The two ends of the connecting rod 11 are connected to the crankshaft 10 and the screen 5 respectively through bearings. An inclined plate 12 is welded to the inner wall of one side of the box body 1. A discharge port 13 is welded to the bottom of one side of the box body 1. The bottom end of the inclined plate 12 is welded to the top of the discharge port 13. A guide plate 14 is welded to the inner wall of the box body 1. An outlet 15 and an outlet 2 16 are respectively installed on the other side of the box body 1 by bolts. The bottom of the other side of the screen 5 is stuck to the bottom of the outlet 15. The bottom end of the guide plate 14 is welded to the inner wall of the bottom of the outlet 2 16. The top end of the guide plate 14 is welded to the top end of the inclined plate 12. The top end of the inclined plate 12 is stuck to the bottom of the screen 5. A conical hopper 17 is welded to the other side of the bottom of the box body 1. A discharge valve 2 18 is installed at the bottom of the conical hopper 17 by bolts. The inner wall of the bottom of the box body 1... A partition 19 is welded to the wall. The screen 5 has two screen holes, one and two, located on opposite sides of the top of the inclined plate 12. Both the guide plate 14 and the inclined plate 12 have through holes. In use, sunflower seeds are poured into the hopper 3. The discharge valve 4 lowers the seeds to the right side of the screen 5. The motor 9, via the crankshaft 10 and connecting rod 11, drives the screen 5 to move back and forth inside the chute 7 via the pulley 6. Sunflower seed debris falls onto the inclined plate 12 from the right side of the screen 5 and is discharged through the outlet 13. Small sunflower seeds fall onto the guide plate 14 through the screen 5 and are discharged through the outlet 16. Large sunflower seeds fall into the outlet 15 from the left end of the screen 5 and are discharged outwards. Dust and debris pass through the screen 5, guide plate 14, and... The mesh on the inclined plate 12 is drawn into the inner side of the air duct 20 by the fan 21. During the screening process, debris generated again falls into the cone hopper 17 and is then discharged outwards through the discharge valve 18. Dust entering the air duct 20 is filtered out by the filter cartridge 23 and filter cover 22, preventing dust from scattering outwards and avoiding solid waste pollution during screening. The motor 27 drives the screw plate 28 to rotate. The screw plate 28, through friction, drives the filter cover 22 and filter cartridge 23 to rotate on the outer ring 24 and inner ring 25, effectively scraping dust from the filter cover 22 and filter cartridge 23 through the gap in the baffle 32 into the inner side of the scraper sleeve 31 and baffle 32. The dust is then spirally pushed by the screw plate 28 into the inner side of the sleeve 29 until it is compacted within the sleeve 29.This allows dust to be pushed open by the screw plate 28 and discharged from the left end of the sleeve 29, enabling real-time cleaning of the filter cover 22 and filter cartridge 23, preventing clogging, ensuring ventilation efficiency, and thus effectively ensuring the absorption of dust generated inside the housing 1.

[0022] The dust removal equipment of this sunflower seed sorting device provides power to all electrical equipment via an external power supply. During operation, sunflower seeds are poured into hopper 3, and discharge valve 4 causes them to fall onto the right side of screen 5. Motor 9, via crankshaft 10 and connecting rod 11, drives screen 5 to move back and forth on the inside of chute 7 via pulley 6. Sunflower seed debris falls onto inclined plate 12 on the right side of screen 5 and is then discharged through outlet 13. Small sunflower seeds fall onto guide plate 14 through screen 5 and are then discharged through outlet 16. Large sunflower seeds fall into outlet 15 through the left end of screen 5 and are discharged outwards. Dust and debris are drawn into the inside of duct 20 by fan 21 through the mesh openings of screen 5, guide plate 14, and inclined plate 12. Debris generated during the sorting process falls onto the cone... Inside the hopper 17, the dust is discharged outward through the discharge valve 18. After entering the air duct 20, the dust is filtered out by the filter cartridge 23 and filter cover 22, preventing the dust from drifting outward and avoiding solid waste pollution during the screening process. The motor 27 drives the screw plate 28 to rotate. The screw plate 28 drives the filter cover 22 and filter cartridge 23 to rotate on the outer ring 24 and inner ring 25 through friction. This effectively scrapes the dust on the filter cover 22 and filter cartridge 23 through the gap of the baffle 32 into the inner side of the scraper sleeve 31 and baffle 32. Then, the screw plate 28 spirals and pushes the dust into the inner side of the sleeve 29 until the dust is squeezed and compacted in the sleeve 29. Then, the dust is pushed open by the screw plate 28 and discharged outward from the left end of the sleeve 29. This allows for real-time cleaning of the filter cover 22 and filter cartridge. 23. Cleaning work is carried out to prevent the filter cover 22 and filter cartridge 23 from being blocked, ensuring ventilation efficiency and thus effectively ensuring the absorption effect of dust generated inside the housing 1. When the fan 21 is working, it drives the impeller 34 to rotate inside the pump casing 33. Using the centrifugal force generated by the impeller 34, the air filtered in the air duct 20 is drawn into the inside of the pump casing 33 from both sides, and then pumped to the inside of the ring pipe 35. The airflow is pumped through the ring pipe 35 to the inside of the upper pipe 36 and the lower pipe 37. The lower pipe 37 blows the airflow from the outside of the filter cover 22 inward through the nozzle 38, and the upper pipe 36 blows the airflow from the inside of the filter cartridge 23 outward through the nozzle 38. Thus, the blowing force of the airflow and the scraping effect of the scraper sleeve 31 are effectively used to clean the filter cover 22 and filter cartridge 23. 3. Cleaning is performed to reduce the adhesion of dust to the filter cartridge 23 and filter cover 22, thereby effectively reducing the friction between the scraper sleeve 31 and the filter cover 22 and filter cartridge 23, and thus effectively reducing the wear of the filter cover 22 and filter cartridge 23, ensuring the service life of the filter cover 22 and filter cartridge 23. During use, when the airflow blows towards the filter cartridge 23 and filter cover 22 through the blowhole 38 in the upper pipe 36 and lower pipe 37, it can effectively blow away the fine dust blocking the filter holes of the filter cartridge 23 and filter cover 22. Due to the resistance of the filter cover 22 and filter cartridge 23 to the airflow, the dust removed is reduced from flying between the filter cartridge 23 and filter cover 22. The suction generated by the spiral push of the screw plate 28 in the sleeve 29 can suck the dust into the space between the scraper sleeve 31 and the baffle sleeve 32.Then, pushed spirally by the screw plate 28 to the inside of the sleeve 29, it effectively prevents fine dust from clogging the inside of the filter holes of the filter cover 22 and filter cartridge 23, effectively ensuring the cleaning effect of the filter cover 22 and filter cartridge 23, and thus ensuring the dust removal effect of the filter cover 22 and filter cartridge 23.
