Abstract
A weir gate assembly includes a substantially rectangular weir gate immersed in a fluidized bed of material with a pair of resilient links rotatably connecting the weir gate and the material conveying trough through which the flow travels. A rotatable arm is pivoted on the housing and is connected to the weir gate such that rotation of the arm varies the configuration of the weir gate within the fluidized bed of material. Rotation of the arm forces a lower weir edge into sealed engagement with the conveying trough and deforms the links such that the relationship of an upper weir edge to the lower weir edge is varied to regulate the depth of the flow. A guide slot with a clamp bolt is provided for guiding rotation of the rotatable arm and maintaining the configuration of the weir gate.
