Embodiment Construction

[0022] Embodiments of the present invention will be described below with reference to the drawings. Such as figure 2 As shown, the waste paper regeneration processing device has a plurality of processing parts constituting the waste paper recycling processing system, and the processing parts include a waste paper input part 1, a pulping part 9, a deinking part 11, a papermaking part 13, a drying part 14, The processing part 15, the white water container part 100 and the deinking waste liquid treatment device 101. Moreover, the waste paper recycling processing apparatus is provided with the control part 700 for controlling the operation|movement of each processing part.

[0023] In the present embodiment, the used paper input unit 1 injects the used paper of a single sheet as a recycling material into the pulping unit 9 . The pulping unit 9 decomposes waste paper in decomposition water, and adjusts it to a waste paper slurry containing waste paper pulp. The used paper input...

Abstract

The control unit operates the stirring device sequentially in a defiberization operating mode, a transition operating mode, and a dilution operating mode. In the defiberization operating mode, the stirring blade is rotated at the revolution speed for defiberization of waste paper in the disaggregating water stored in the stirring chamber to generate a waste paper pulp slurry. In the transition operating mode, the dilution water from the water supply unit is supplied to the waste paper pulp slurry while rotating the stirring blade at the revolution speed for defiberization to stir the waste paper pulp slurry. In the dilution operating mode, the dilution water from the water supply unit is supplied to the waste paper pulp slurry while rotating the stirring blade at the revolution speed for stirring, lower than the revolution speed for defiberization, to stir the waste paper pulp slurry.

Description

technical field [0001] The present invention relates to a waste paper regeneration processing device which is installed in an office or the like which is a place where waste paper is generated, and which regenerates paper. Background technique [0002] Conventionally, waste paper regeneration processing apparatuses include, for example, a waste paper input unit, a pulping unit, a deinking unit, a papermaking unit, a drying unit, and a control unit for controlling operation. The used paper input part supplies the recycled raw material used paper to the pulping part. The pulping section decomposes waste paper and prepares waste paper slurry containing waste paper pulp. The deinking section deinks the waste paper slurry and prepares deinked pulp. The papermaking section manufactures wet paper from deinked waste paper slurry. The drying section dries the dehydrated wet paper. [0003] The pulping part has a stirring tank, a stirring blade arranged in the stirring tank, and a...
