Definitions

  • This invention relates to a furnace, more particularly to a furnace including a stirring rod having an inclined face for stirring a combustible material on a perforated tray.
  • a conventional furnace normally includes: a furnace housing; a perforated tray mounted in the furnace housing, dividing the inner space into upper and lower chambers, adapted to support a combustible material thereon, and formed with a plurality of apertures for passage of ash therethrough; a stirring rod disposed rotatably on the perforated tray for stirring the combustible material on the perforated tray; and a shaft extending through the perforated tray to connect with the stirring rod so as to drive rotation of the stirring rod using a motor.
  • the motor is actuated to drive rotation of the stirring rod, which results in stirring of the combustible material and ash formed from combustion of the combustible material on the perforated tray, which, in turn, results in falling of the ash through the apertures in the perforated tray to a bottom exit of the furnace.
  • the object of the present invention is to provide a furnace that can overcome the aforesaid drawback associated with the prior art.
  • a furnace comprises: a furnace housing defining an inner space therein; a perforated tray mounted in the furnace housing, dividing the inner space into upper and lower chambers, adapted to support a combustible material thereon, and formed with a plurality of apertures for passage of ash therethrough; and a stirring rod disposed rotatably on the perforated tray for stirring the combustible material on the perforated tray.
  • the stirring rod has top and bottom ends, two opposite lateral ends, a middle portion, and opposite first and second portions, each of which extends from the middle portion to a respective one of the lateral ends.
  • Each of the first and second portions has an inclined face that extends between the top and bottom ends of the stirring rod from the respective one of the lateral ends toward the middle portion of the stirring rod, that is inclined relative to the perforated tray, and that faces toward the perforated tray.
  • Figs. 1 to 4 illustrate the preferred embodiment of a furnace 2 of this invention for burning a raw material, such as hull and shell waste of agricultural crops.
  • the furnace 2 includes: a furnace housing 21 defining an inner space 211 therein; a perforated tray 22 mounted in the furnace housing 21, dividing the inner space 211 into upper and lower chambers 2111, 2112, adapted to support a combustible material thereon, and formed with a plurality of apertures 222 for passage of ash therethrough; and a stirring rod 4 disposed rotatably on the perforated tray 22 for stirring the combustible material on the perforated tray 22.
  • the stirring rod 4 has top and bottom ends 40, 41, two opposite lateral ends 42, a middle portion 43, and opposite first and second portions 46, 47, each of which extends from the middle portion 43 to a respective one of the lateral ends 42.
  • Each of the first and second portions 46, 47 of the stirring rod 4 has an inclined face 45 that extends between the top and bottom ends 40, 41 of the stirring rod 4 from the respective one of the lateral ends 42 toward the middle portion 43 of the stirring rod 4, that is inclined relative to the perforated tray 22, and that faces toward the perforated tray 22.
  • Each of the first and second portions 46, 47 of the stirring rod 4 further has an outer segment 461, 471 extending from the respective one of the lateral ends 42 of the stirring rod 4, and an inner segment 462, 472 bent from the outer segment 461, 471 and extending therefrom to the middle portion 43 of the stirring rod 4 such that the outer and inner segments 461, 462 (471, 472) of each of the first and second portions 46, 47 of the stirring rod 4 form an angle of less than 180 degrees and greater than 90 degrees therebetween.
  • each of the first and second portions 46, 47 of the stirring rod 4 is tapered from the middle portion 43 to the respective one of the lateral ends 42 of the stirring rod 4.
  • the furnace 2 further includes a driving unit 20 including a motor 24 with an output shaft 23 that extends through the perforated tray 22 and into the upper chamber 211 of the furnace 2.
  • the middle portion 43 of the stirring rod 4 is formed with a non-circular hole 31 for extension of the output shaft 23 thereinto so as to permit the stirring rod 4 to be driven by the output shaft 23 of the motor 24.
  • the inclined faces 45 of the first and second portions 46, 47 of the stirring rod 4 are disposed respectively at two opposite sides of the stirring rod 4.
  • the combustible material and ash are stirred by the stirring rod 4 upon actuation of the motor 24 so as to enhance combustion of the combustible material and to permit falling of the ash through the apertures 222 in the perforated tray 22 into a bottom exit 25 of the furnace 2 for further treatment.
  • the inclined faces 45 of the first and second portions 46, 47 of the stirring rod 4 push the ash to pass through the apertures 222 in the perforated tray 22, thereby facilitating removal of the ash from the perforated tray 22 and reducing the accumulated amount of the ash in a gap between the stirring rod 4 and the perforated tray 22.
  • each of the first and second portions 46, 47 of the stirring rod 4 enhances stirring and circulation of the combustible material and the ash on the perforated tray 22. Furthermore, the tapered shape of each of the first and second portions 46, 47 of the stirring rod 4 reduces the contact area of the respective inclined face 45 that is in contact with the combustible material and the ash, thereby reducing the resistance to rotation of the stirring rod 4 attributed to the combustion material and the ash.
