DRY-TYPE DISINTEGRATOR/DEFIBRATOR

PROBLEM TO BE SOLVED: To provide a dry-type disintegrator/defibrator that carries out preliminary defibration of pulp kept in a dry condition to produce a raw material for the production of a cellulose nanofiber. SOLUTION: The dry-type disintegrator/defibrator comprises a feed port 3 for feeding pulp or the like， a discharge port 5 for discharging defibrated material， and a defibration chamber 7 disposed between the feed port 3 and the discharge port 5. A screen 9 comprising a plurality of through holes 31 is provided between the discharge port 5 and the defibration chamber 7. A rotor 11a is provided in the defibration chamber 7. The rotor 11a is constituted of a rotary shaft 13a and a plurality of plate-shaped stationary blades 17 fixed to the rotary shaft 13a with a prescribed gap 33 apart from each other in the shaft direction thereof. Each of the stationary blades 17 comprises a plurality of edges 15 protruding in the direction away from the rotary shaft 13a. The inner face 35 of the defibration chamber 7 is provided with at least one protrusion 19a. The protrusion 19a comprises a plurality of recessed parts 21 for the edges 15 of each of the fixed blades 17 to travel therethrough when the rotor 11a rotates. SELECTED DRAWING: Figure 1

要解决的技术问题：提供一种干式疏解解离机（dry-type disintegrator/defibrator），可对处于干燥状态的纸浆进行初步疏解，以制备纤维素纳米纤维的生产原料。
技术方案：该干式疏解解离机包括用于输送纸浆等物料的进料口3、用于排出疏解后物料的出料口5，以及设置于进料口3与出料口5之间的疏解腔7。在出料口5与疏解腔7之间设置有开设有多个通孔31的筛网9。疏解腔7内设有转子11a，该转子11a由旋转轴13a以及沿其轴向以指定间隙33固定于旋转轴13a上的多个板状定刀片17构成。每个板状定刀片17均设有多个沿远离旋转轴13a的方向凸出的刀刃15。疏解腔7的内壁35设有至少一个凸起19a，该凸起19a开设有多个凹槽21，用于在转子11a旋转时供各板状定刀片17的刀刃15穿行通过。
