Problems solved by technology

[0003] But, in the dissociation device of above-mentioned paper making raw material, as Figure 8 As shown, since the papermaking raw material 202 is combed up by the holding part (protrusion) 201 provided on the inner wall of the rotating drum 200, and the papermaking raw material 202 is made to fall naturally, the papermaking raw material 202 is dissociated, so the efficiency is low and a large amount of processing time is spent. , at the same time, the length of the rotary drum 200 is also large, and further, there is a problem of occupying a large installation space.

Embodiment Construction

[0025] Next, an apparatus for disintegrating paper-making stock and a method for disintegrating paper-making stock according to an embodiment of the present invention will be described with reference to the accompanying drawings. exist Figure 1 to Figure 6 Among them, A is a dissociation device for papermaking raw materials, and the rotating drum 1 of the dissociation device A for papermaking raw materials is supported in a freely rotatable manner. 13 is supported for free rotation.

[0026] The driving roller 13 is driven by a motor 14 , and the driving roller 13 is provided with an engagement portion 15 that engages with the driving roller 13 provided on the outer periphery of the rotary drum 1 . Such as figure 2 and image 3 As shown, the driving roller 13 rotates counterclockwise, and the rotating drum 1 slowly rotates clockwise (for example, 10˜20 rpm).

[0027] On the rotary drum 1, a holding portion (for example, protrusion) 16 for holding the papermaking stock 2 ...

Abstract

A dissociating apparatus (A) of papermaking raw material includes a rotary drum (1) for receiving the papermaking raw material therein. The rotary drum (1) has an engaging portion (16) on an inner wall (17) thereof for engaging the papermaking raw material. The dissociating apparatus (A) also includes a rotary vane (3) disposed inside the rotary drum (1) for hitting the papermaking raw material (2) falling from the engaging portion (16).

Description

technical field [0001] The present invention relates to a dissociation device for papermaking raw materials and a method for dissociation of papermaking raw materials, in particular to a dissociation device for papermaking raw materials and a dissociation method for papermaking raw materials with improved dissociation efficiency. Background technique [0002] When processing papermaking raw materials, such as used paper and used corrugated cardboard, as recycled paper, since the papermaking raw materials received by the processing factory are compressed by a press, the compressed The papermaking raw materials are dispersed, and then, the dispersed papermaking raw materials are introduced into the rotating drum, water is sprayed in the rotating drum, and the paper making raw materials are combed up by the holding part (protrusion) provided on the inner wall of the rotating drum to make them naturally Falling slowly dissociates papermaking raw materials. [0003] But, in the ...
