PAPER MATERIAL SCREENING/REFINING APPARATUS |
摘要 |
A paper material screening and refining apparatus has a tank which receives a paper material to allow the paper material to accumulate therein; a cylindrical screen which divides the space in the tank into a primary chamber and a secondary chamber; a cylindrical rotary member carried by a rotary shaft and disposed so as to oppose to the screen; a rotational member carried by the rotary shaft and disposed near the end of the tank remoter from the paper material receiving end of the tank; a water supply pipe for supplying water into the primary chamber from the region near the rotational member; a water supply valve provided in the water supply pipe; a discharge pipe for discharging the paper material in the primary chamber of the tank from a region near the rotational member; and a discharge valve provided in the discharge pipe. Water is introduced into the primary chamber from a region near the rotational member, so as to dilute the material liquid or slurry and to realize a state resembling "scrambling washing" as a result of collision between the introduced water and the paper material, thus promoting dissociation of the paper material, whereby the paper material is efficiently screened and refined by the screen.
