ある工場ではその設置ができ々い問題点があった。Problems to be Solved by the Invention The conventional paper manufacturing screen described above has a screen frame 10.
Since the object is fed by the back-and-forth vibration in the oscillation of the
The number of rotations of the shaking means 11 of the I + - frame 10 is set to 70 OR.
Although the setting is higher than -P-M, such high-speed driving causes vibrations that travel far along the ground, and this vibration can cause nearby residents to lose sleep. There was a problem in the installation of factories located in residential areas.

ものである。Function: In the papermaking screen constructed as described above, when the shaking means 4 of the screen frame 2 is rotated at a speed of about 33 OR, -P-M, the screen frame 2 is shaken at this speed, and the screen frame 2 is shaken at this speed. The vertical vibration sieves the paper stock and foreign substances, and the vertical movement of the screen frame 2 raises and lowers the small compartment 7 provided below the screen plate 6 in the water.
In order to function as a water gun in each small compartment 7, when the screen frame 2 is lowered, water blows up from each small compartment 7 through the pump I/-) 6 and lifts the object to be sent. When the screen frame 2 is moving backwards and forwards, the screen frame 2 moves backward to catch the object coming down and moves forward.
Even if the number of rotations is low as described above, the screen plate 6 is reliably fed and ejected from the screen plate 6, and furthermore, at this speed of rotation, vibrations that are transmitted far away are not generated.

The screen frame 2 may be formed so that the side surface shape is flat on the paper inlet side and upwardly sloped on the outlet side as shown in Fig. 3, or as shown in Fig. 3. Either the entire surface is inclined so that the outlet side is higher than the inlet side of the stock, as shown in Figure 1, or the entire surface is flat and a discharge groove 5 is provided on the rear side, as shown in Fig. 1. be.

) Since it performs the action of a water gun that blows upwards in 6, it is better to have a small cross-sectional area (the smaller the cross-sectional area, the more difficult and expensive it is to manufacture, so it is as effective and inexpensive as possible). The cross-sectional area shall be set by taking into account the size of the screen plate 6, the paper stock concentration, and other conditions.

Even if the number of revolutions of the shaking means of the screen plate is reduced to less than half of the conventional speed, the objects can be reliably distributed, and the object can be transmitted at all speeds on the ground, preventing a good night's sleep. Since it does not generate any vibration, it has a unique effect that allows it to be installed in a factory in a residential area and operated late at night.
