Chip conveyor

An apparatus for conveying and separating liquids and solids deposited therein, comprising:

• a pair of inclined, upwardly opening, adjacent and elongated trough means extending parallel to each other;
• an inclined, elongated helical flight disposed in each said trough means for rotation about its longitudinal axis;
• drive means for effecting rotation of said helical flights;
• tank means secured to said trough means and receiving the lower ends of said helical flights, said tank means having spaced and upright first wall means;
• a pair of second wall means disposed within said receiving tank means between and spaced from said first wall means for receiving said liquids and solids therebetween, said second wall means extending above the top of at least a portion of each said first wall means;
• and
• elongated edge means defining said portion of the top of each said first wall means, said edge means being adjustable about a horizontal axis transverse of said first wall means;
• each said first wall means comprising an upright side wall having a recessed portion in the top edge thereof;
• each said elongated edge means comprising a plate having a linear top edge and disposed against a side wall substantially parallel thereto to partially cover said recessed portion;
• means pivotally supporting said plate on said side wall for effecting said adjustment of said top edge;
• and
• means for releasably securing said plate against pivotal movement and in a position in which said top edge of said plate is substantially horizontal;
• whereby said solids introduced between said second wall means are conveyed by said rotating flights to the upper ends of said trough means and said liquid introduced between said second wall means passes under said second wall means and overflows the tops of said edge means.
