As shown in the figure, a sealed tank (1) is connected to a raw material inflow chamber (2) by a circular porous recessed member called a screen cylinder.
The raw material inflow chamber (2) is divided into a passing raw material receiving chamber (3) and a raw material inflow chamber (2).
A screen rotor (4) is disposed in the fourth cylinder, and as the screen rotor (4) rotates, the raw material flows into the raw material inflow chamber (2) from the raw material inlet (5) and is passed through the screen cylinder (6). The raw material that has passed through the screen cylinder (6) and flowed into the raw material receiving chamber (3) is transferred to the raw material outlet (7).
) and a part of the raw material that did not pass through the screen cylinder (6) is discharged from the bottom of the raw material inflow chamber (2),
A structure is already known in which the scraper (8) of the screen rotor (4) works to continuously pass through the raw material while avoiding clogging of the screen surface of the screen cylinder (6). . In the figure, (9) is the rotating body of the screen rotor (4), α is the support rod for attaching the scraper (8) to the rotating body (9), al is the drive shaft connected to the rotating body (9), ( (b) The bearing of the drive shaft α and the drive shaft (H is a large pulley (to), a power bell)

異物を取除かなければならない不都合が生じる。However, when such a screen processing device is incorporated into waste paper recycling equipment, the following problems arise. That is, in this case, foreign matter such as vinyl strings that bound the waste paper flows into the raw material inflow chamber (2) together with the raw material in which the waste paper is melted, but if this foreign matter -bi is very large, it may cause the support of the rotating screen rotor. Since foreign objects become entangled with the rod αQ, there arises the inconvenience that the operation must be stopped frequently to remove the foreign objects.
