The invention eliminates excessive cutting of crushed aggregates fiber by a mechanical pulping mode through the inclined plate A9, the inclined plate B14 and the middle shear plate 11 in the tide pulping device, reduces the damage rate of the fiber, realizes nondestructive crushing and decomposition of the fiber in the crushed aggregates, and improves the quality of slurry; when the driven cam 6 pushes the roller 18 and the feed box 8 to move upwards and incline, the crushed aggregates can freely collide with the inclined plate B14 and promote the crushed aggregates to be crushed and decomposed, the two ends of the feed box 8 are sequentially and repeatedly inclined, the mixed liquid in the feed box 8 is promoted to form tidal motion like sea waves, the crushed aggregates can be freely beaten and crushed and decomposed, the defect that the mechanical rotor forcedly breaks the crushed aggregates is overcome by the pulping mode, namely, the fibers of the crushed aggregates are excessively cut off by the mechanical rotor, and the quality of pulp is influenced; the tide type free beating crushing decomposition of the crushed aggregates eliminates excessive cutting of crushed aggregates fiber, and the nondestructive crushing decomposition of the fiber in the crushed aggregates is realized, so that the quality of slurry is improved. In addition, the middle shear plate 11 in the tide pulping device has the function of carrying out auxiliary shearing and crushing on hard crushed aggregates which are not easy to decompose, namely, the triangular saw teeth 24 on the middle shear plate 11 are utilized to carry out shearing, crushing and decomposing on the hard crushed aggregates, so that the overall pulping efficiency of the equipment is improved.
According to the invention, the inclined plate A9 and the inclined plate B14 are arranged to form an included angle of 45 degrees with the feed box 8, so that free collision, crushing and decomposition of crushed aggregates are realized, automatic upward movement of the crushed aggregates is realized, and the crushed aggregates are prevented from precipitating, namely, when the crushed aggregates collide freely, as the inclined plate A9 and the inclined plate B14 form an angle of 45 degrees, the crushed aggregates have component force of upward movement after collision, and the upward component force can promote the crushed aggregates to move upward after collision.
The inclined plates A9 and B14 are provided with the parallel holes 15, and the filtering of crushed aggregates is realized through the design, namely, after the large crushed aggregates 12 in the coarse pulp area 10 are broken and decomposed through tide type free collision, the small crushed aggregates 16 meeting the requirements enter the fine pulp area 30 through the parallel holes 15, so that a foundation is provided for realizing homogeneous slurry.
