Definitions

  • the present invention relates to a static dust-collecting device, and more particularly to a static dust-collecting device installed in a smoke exhaustion for attracting oil drops.
  • Fig. 11 shows a conventional static dust-collecting device including an electro-separation section 61 which enables oil drops in the air to entrain charge.
  • a dust-collecting section 62 formed by multiple vertical panels is disposed on rear side of the electro-separation section 61.
  • Two scrapers 65 are disposed on two sides of each dust-collecting device 62.
  • the scrapers 65 are driven by a motor 63 via thread rods 64 to move up and down for scraping off the oil dirt attaching to the dust-collecting section 62.
  • the electro-separation section 61 makes the oil drops passing therethrough entrain charge to be attracted by the rearward dust-collecting section 62.
  • the installation of the electro-separation section 61 leads to increment of cost for equipment.
  • Fig. 12 shows another type of static dust-collecting device including a dust-collecting section 72 formed by multiple circular dust-collecting boards 721 and driven by a shaft 71. Two sides of each dust-collecting board 721 are respectively disposed with scrapers 73. In such device, it is still necessary to install an electro-separation section 74 in front of the dust-collecting section 72. Therefore, the cost for equipment is still high.
  • the dust-collecting device includes multiple tubes carrying negative or positive charge.
  • a driving member carrying positive or negative charge is extended through each tube.
  • the driving member is driven by a driving mechanism for driving a scraper to scrape off oil dirt attaching to inner wall of the tube.
  • the driving member also enables oil drops entrained in the smoke to entrain positive or negative charge, whereby the oil drops are attracted by the tube. Therefore, the driving member also serves as an electro-separation section to reduce the manufacturing cost.
  • the present invention is installed in a smoke exhaustion 1 of a kitchen.
  • the smoke exhaustion 1 has a smoke funnel 12 mounted above a cabinet (not shown).
  • the smoke funnel 12 is connected with a housing 13 having two open ends and two turn sections 131, 132.
  • the first turn section 131 has a washing sink 38 free from the path of the smoke path.
  • An exhaustion fan 2 is installed at a rear end of the housing 13.
  • a static dust-collecting device 3 is installed between the two turn sections 131, 132.
  • the dust-collecting device 3 includes multiple circular tubes 31 made of metal.
  • a stopper board 32 is disposed at each end of the tubes 31 to block the space between the tubes 31, the interior of the housing 13, except the tubes 31, is in a sealed state.
  • Two opposite sides of the tube 31 are respectively formed with two recessed guide sections 311.
  • a guide bar 312 is connected with each end of the guide sections 311.
  • the guide bar 312 has an inner face shaped as the inner face of the guide section 311.
  • a thread rod 33 is coaxially passed through and located in the tube 31 with two ends extending out of two ends of the tube 31.
  • the thread rod 33 drives a scraper 34 screwed thereon to reciprocally move.
  • the blade of the scraper 34 abuts against the inner wall of the tube 31.
  • each thread rod 33 is disposed with a driven gear 35 driven by the same driving gear 36 which is driven by a motor 37.
  • the other end of the thread rod 33 extends into the washing sink 38.
  • One side of the washing sink 38 is disposed with multiple nozzles 381 respectively aimed at the scrapers 34 lowered to a lowest position.
  • the nozzles 381 serve to inject a washing detergent sent out by a pump 39.
  • the present invention is first installed in the housing 13.
  • the motor 37, driving gear 36 and driven gear 35 are disposed on outer side of the second turn section 132 of the housing 13.
  • the smoke exhaustion 1 is installed in the kitchen for exhausting smoke entraining numerous oil drops.
  • the thread rod 33 is connected with a positive electrode to carry positive charge.
  • the tube 31 is connected with a negative electrode to carry negative charge.
  • the oil drops accumulating on the inner wall of the tube 31 will form a layer of oil dirt which will deteriorate the attraction of the tube 31 to the oil drops. Therefore, it will be necessary to clear up the oil dirt.
  • the power for the thread rod 33 and the tube 31 is first turned off. Then the motor 37 is powered on to drive the driving gear 36 to rotate. Accordingly, the driven gears 35 are driven by the driving gear 36 to rotate for driving the thread rod 33.
  • the recesses 341 of the scraper 34 are engaged with the guide sections 311 of the tube 31 so that the scraper 34 is prevented from rotating and will move toward the other end. Therefore, the scraper 34 will go into the tube 31 to scrape off the oil dirt therein as shown in Fig. 5. After the scraper 34 passes through the tube 31, the inner wall of the tube 31 is cleaned up and the scraper 34 carries the oil dirt out.
  • the pump 39 is activated and the washing detergent is injected from the nozzles 381 to the scraper 34 for washing the same as shown in Fig. 6. After cleaned, the washing detergent flowing into the washing sink 38 is drained. Finally, the scraper 34 is restored to its home position for next use.
  • the thread rod 33 is able to drive the scraper 34 to scrape off the oil dirt. Also, the thread rod 33 carries positive charge, enabling the oil drops getting into the static dust-collecting device 3 to entrain positive charge. Therefore, the thread rod 33 serves as the electro-separation section of a conventional static dust- collecting device so as to reduce the cost for the device.
  • the housing 41 has a rectangular cross-section. Multiple tubes 42 with rectangular cross-section are disposed in the housing 41. Two ends of the tube 42 are connected with multiple guide bars 43. A reciprocally movable scraper 44 is disposed in each tube 42. The scraper 44 is driven by a endless loop-like steel cable 45 driven by a first motor 46. In one end of the housing 41 is disposed a brush 48 driven by a second motor 47. In this embodiment, the housing 41 is free from any turn section as seen in the first embodiment.
  • the motor 46 drives the steel cable 45 to move and drive the scraper 44 to scrape off the oil dirt in the tube 42.
  • the second motor 47 drives the brush 48 to clean up the scraper 44.
  • the guide bars 43 serve to guide the scraper 44 without deflection, whereby when the scraper 44 returns to its home position, the scraper 44 can still smoothly get into the tube 42.
  • the driven gear 51 at one end of the thread rod 33 is driven by a spiral rod 52 instead of the driving gear.
  • the spiral rod 52 is driven by a motor 54 disposed on one side of the housing 53.
  • the spiral rod 52 serves to drive multiple driven gears 51 at one time so that the thread rods 33 can be effectively rotated and the occupied space is reduced.
  • the tube can carry positive charge, while the thread rod can carry negative charge.
