Description
- This application claims priority of Taiwanese application no.
096210756, filed on July 2, 2007 - 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.
- In operation, 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.
- Since there exists a gap between the perforated tray and the stirring rod, undesired accumulation of combustible material and ash in the gap is likely to occur, which can hinder rotation of the stirring rod.
- Therefore, the object of the present invention is to provide a furnace that can overcome the aforesaid drawback associated with the prior art.
- According to the present invention, 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.
- In drawings which illustrate an embodiment of the invention,
-
Fig. 1 is a fragmentary schematic partly sectional view of the preferred embodiment of a furnace according to this invention; -
Fig. 2 is an exploded perspective view of an assembly of a perforated tray and a stirring rod of the preferred embodiment; -
Fig. 3 is an assembled perspective view of the assembly of the perforated tray and the stirring rod of the preferred embodiment; and -
Fig. 4 is an enlarged partly sectional view of an encircled portion inFig. 3 . -
Figs. 1 to 4 illustrate the preferred embodiment of afurnace 2 of this invention for burning a raw material, such as hull and shell waste of agricultural crops. - The
furnace 2 includes: afurnace housing 21 defining aninner space 211 therein; aperforated tray 22 mounted in thefurnace housing 21, dividing theinner space 211 into upper andlower chambers apertures 222 for passage of ash therethrough; and astirring rod 4 disposed rotatably on the perforatedtray 22 for stirring the combustible material on the perforatedtray 22. Thestirring rod 4 has top andbottom ends lateral ends 42, amiddle portion 43, and opposite first andsecond portions middle portion 43 to a respective one of thelateral ends 42. Each of the first andsecond portions stirring rod 4 has aninclined face 45 that extends between the top andbottom ends stirring rod 4 from the respective one of thelateral ends 42 toward themiddle portion 43 of thestirring rod 4, that is inclined relative to theperforated tray 22, and that faces toward theperforated tray 22. - Each of the first and
second portions stirring rod 4 further has anouter segment lateral ends 42 of thestirring rod 4, and aninner segment outer segment middle portion 43 of thestirring rod 4 such that the outer andinner segments 461, 462 (471, 472) of each of the first andsecond portions stirring rod 4 form an angle of less than 180 degrees and greater than 90 degrees therebetween. Preferably, each of the first andsecond portions stirring rod 4 is tapered from themiddle portion 43 to the respective one of thelateral ends 42 of thestirring rod 4. - The
furnace 2 further includes adriving unit 20 including amotor 24 with anoutput shaft 23 that extends through theperforated tray 22 and into theupper chamber 211 of thefurnace 2. Themiddle portion 43 of thestirring rod 4 is formed with anon-circular hole 31 for extension of theoutput shaft 23 thereinto so as to permit thestirring rod 4 to be driven by theoutput shaft 23 of themotor 24. - In this embodiment, the
inclined faces 45 of the first andsecond portions stirring rod 4 are disposed respectively at two opposite sides of thestirring rod 4. - In operation, the combustible material and ash are stirred by the stirring
rod 4 upon actuation of themotor 24 so as to enhance combustion of the combustible material and to permit falling of the ash through theapertures 222 in theperforated tray 22 into abottom exit 25 of thefurnace 2 for further treatment. During rotation of thestirring rod 4, theinclined faces 45 of the first andsecond portions stirring rod 4 push the ash to pass through theapertures 222 in theperforated tray 22, thereby facilitating removal of the ash from theperforated tray 22 and reducing the accumulated amount of the ash in a gap between thestirring rod 4 and theperforated tray 22. Moreover, the angle between the inner andouter segments 461, 462 (471, 472) of each of the first andsecond portions stirring rod 4 enhances stirring and circulation of the combustible material and the ash on theperforated tray 22. Furthermore, the tapered shape of each of the first andsecond portions stirring rod 4 reduces the contact area of the respectiveinclined face 45 that is in contact with the combustible material and the ash, thereby reducing the resistance to rotation of thestirring rod 4 attributed to the combustion material and the ash. - With the inclusion of the
stirring rod 4 in the furnace of this invention, the aforesaid accumulation problem associated with the prior art can be considerably alleviated.
