Pulp concentration adjusting method and device for used paper recycling apparatus

A pulp concentration adjusting device for a used paper recycling apparatus for adjusting the concentration of used paper pulp manufactured in a pulp making device in divided portions for use in a used paper recycling apparatus of furniture size small enough to be installed at the site of origin of used paper, comprising:

• used paper pulp dividing means for dividing a specified portion from the whole volume of used paper pulp manufactured in pulp making device in preceding process,
• concentration adjusting means for adding water for adjusting concentration to the divided portion of used paper pulp divided by the pulp dividing means, and
• control means for controlling the used paper pulp dividing means and the concentration adjusting means in interlock,
• wherein the control means controls the used paper pulp dividing means and the concentration adjusting means in interlock, so as to divide a specified portion from the whole volume of used paper pulp manufactured in pulp making device in preceding process, add water for adjusting concentration to the divided portion of used paper pulp, and adjust the total volume of the divided portion of used paper pulp and water to a specified value, thereby preparing a pulp suspension of specified concentration.

A used paper recycling apparatus comprising, in an apparatus case of furniture size, a pulp making section for manufacturing used paper pulp by macerating and mashing used paper, a pulp concentration adjusting section for adjusting the concentration of used paper pulp manufactured in this pulp making section, a paper making section for manufacturing recycled paper from used paper pulp adjusted in concentration in this pulp concentration adjusting section, and a control section for driving and controlling the pulp making section and paper making section in interlock,

• wherein the pulp concentration adjusting means includes used paper pulp dividing means for dividing a specified portion from the whole volume of used paper pulp manufactured in pulp making device in preceding process, concentration adjusting means for adding water for adjusting concentration to the divided portion of used paper pulp divided by the pulp dividing means, and control means for controlling the used paper pulp dividing means and the concentration adjusting means in interlock, and
• the control means controls the used paper pulp dividing means and the concentration adjusting means in interlock, so as to divide a specified portion from the whole volume of used paper pulp manufactured in pulp making device in preceding process, add water for adjusting concentration to the divided portion of used paper pulp, and adjust the total volume of the divided portion of used paper pulp and water to a specified value, thereby preparing a pulp suspension of specified concentration.
