  • Flexible chicane system for liquid-solid separation equipment
    Patent number: 4729836
    Abstract: A chicane system is provided in a belt filter press in a gravity drainage zone. The gravity drainage zone includes a movable filter belt, an inlet for distributing a suspension on the filter belt and an outlet for discharging separated liquid and solid components of the suspension. A support rod is mounted over the filter belt and has a longitudinal axis generally perpendicular to the filter belt movement. A plurality of flow turners depend from the support rod and engage the filter belt to prevent clogging of the filter belt by the suspension solid component. Each flow turner includes a plow portion extending into the suspension and engaging the filter belt and a leaf spring portion fixed at one end to the support rod and at an opposite end to the plow portion. Each leaf spring portion is stressed to bias and force its plow portion against the filter belt.
