Vacuum dehydration is commonly used in the paper industry process, the use of water ring vacuum pump vacuum dehydration, the specific process is very complex, is a typical case of vacuum dehydration, the following process will be described in detail the specific process. The general process of papermaking is as follows: raw material - slicing - cooking - washing - screening - bleaching - beating - vacuum dehydration (using water ring vacuum pump) - squeezing dehydration - drying - molding - factory. Pulp after beating, contains a lot of water, the water must be removed in order to make the finished pulp, vacuum dewatering pulp dewatering is the first stage. Vacuum dehydration process is, the pulp sprayed into the copper mesh woven into a thin grid with. Under the copper mesh belt, a vacuum box is set at regular intervals, vacuum tube is connected to the vacuum box, and then the intake pipe of the water ring pump is connected. Due to the vacuum caused by the water ring pump, the water in the copper mesh belt can be sucked into the pipeline to achieve the purpose of dehydration.
