Abstract
A device and method for regulating pressure in a flock feed include a storage device disposed for receipt of fiber flocks, an exhaust air fan having a drive, and a controller in communication with the drive. A filling level measurement device and a pressure measurement device are provided in the storage device. The controller is configured to regulate the drive to achieve a target pressure as sensed by the pressure measurement device that is based on a filling level of the fiber flocks determined by the filling level measurement device.
Claims6
A device for regulating pressure in a flock feed, comprising:
- a storage device disposed for receipt of fiber flocks;
- an exhaust air fan having a drive;
- a controller in communication with the drive;
- a filling level measurement device and a pressure measurement device provided in the storage device;
- wherein the controller is configured to regulate the drive to achieve a target pressure as sensed by the pressure measurement device that is based on a filling level of the fiber flocks determined by the filling level measurement device;
- wherein the target pressure in the controller assigned to the filling level increases continuously with a decrease in the filling level;
- and
- wherein the controller regulates the drive to maintain a pressure on the fiber flocks at a lower boundary of the storage device constant.
A method for regulating pressure in a flock feed that includes a storage device for filling with fiber flocks and an exhaust air fan with a drive, comprising:
- measuring a filling level of the fiber flocks in the storage device;
- measuring a pressure a pressure in the storage device;
- determining a target value for the pressure in the storage device based the measured filling level;
- regulating the pressure in the storage device to achieve the target value by controlling the drive of the exhaust air fan;
- and
- wherein the target value for the pressure in the storage device decreases with an increase in the filling level of the fiber flocks in the storage device.
