Particle cleaning apparatus

Claim 1

A particle cleaning device comprising an enclosure having top, bottom, and side walls forming a chamber, an input opening formed in said side wall adjacent one end of said chamber for receiving the particles to be cleaned, a second opening formed in said enclosure adjacent the other end of said chamber and spaced from the input opening for discharging the particles from said chamber, said input and second opening being formed in said side walls adjacent the lower end of said enclosure, baffle means disposed between said input and second openings and extending upwardly from the bottom wall of said enclosure the upper end of said baffle means being spaced from the top wall of said enclosure, said chamber being inclined downwardly from said input opening to said second opening, said side walls diverging outwardly from their lower ends to their upper ends, high pressure fluid input means coupled to said enclosure and opening into the lower end of said chamber adjacent to said input opening and between said input opening and said baffle means for projecting said particles upwardly at high velocity into said chamber for agitated movement around said baffle means and in a circuitous path between said input and second openings for discharging from said second opening, and suction means opening into the top wall of said enclosure and in spaced relation to said high pressure input means and said input opening for removing from said chamber dust and foreign matter separated from said particles.
