Machine for manufacturing paper, in particular recycled paper

摘要

The machine for manufacturing recycled paper from aqueous fibrous pulp, comprises a device, which has feeding device and centrifugal separating device (14) and which is intended for precipitating calcium carbonate from reaction partner that is dissolved in water and/or for drawing-off the calcium carbonate. The device has a filter mechanism and collecting devices (5, 6) for extracting water from fibrous pulp by a transport filter (3). The water is largely extracted from the fibrous pulp up to releasing the final product. The extracted water is collected in the collecting device. The machine for manufacturing recycled paper from aqueous fibrous pulp, comprises a device, which has feeding device and centrifugal separating device (14) and which is intended for precipitating calcium carbonate from reaction partner that is dissolved in water and/or for drawing-off the calcium carbonate. The device has a filter mechanism and collecting devices (5, 6) for extracting water from fibrous pulp by a transport filter (3). The water is largely extracted from the fibrous pulp up to releasing the final product. The extracted water is collected in the collecting device and is re-used in a device component or in a clarifying device by pipelines. The device has downstream neutralizing device (17) for neutralizing the consumed precipitation by changing the pH-value of water. The centrifugal separating device is used for the separation and removal of the calcium carbonate from water, and is arranged upstream of the feeding device and downstream of the neutralizing device.
