Embodiment 1
[0043] Such as figure 1 As shown, this embodiment provides a waste paper recycling process that fundamentally solves waste paper recycling pollution, which includes the following specific steps:
[0044] (1) Pulping: First, cleanly produce the waste paper raw materials to remove the sundries in the waste paper raw materials; The filter plate in the hydrolysis machine 201 is filtered and discharged into the pulp storage tank 202; the pulp in the pulp storage tank 202 is transported to the refiner 203 by a pulp pump for pulping, and the pulp after rubbing enters the pulping tank 204; the slurry in the slurry tank 204 is transported to the feed box 205 by the slurry pump, and then fed to the mixing tank 206 by the feed box 205; the storage time of the slurry in the slurry storage tank 202 is no more than 6 hours;
[0045] (2) Papermaking: The slurry in the mixing tank 206 is transported to the desander 207, and after desanding by the desander 207, the slurry is sent to the net c...
Embodiment 2
[0051] Based on the waste paper regeneration process in Embodiment 1 that fundamentally solves waste paper regeneration pollution, this embodiment provides corresponding equipment, which includes: a hydrolysis machine 201, a stock tank 202, a refiner 203, and a pulp tank 204, material box 205, mixing tank 206, sand remover 207, cage 211, cage 210, blanket 209, vacuum pump 219, press 218, idler 220, drying cylinder 208 and fiber concentrator 222; hydrolysis machine 201 A filter plate for filtering slurry is arranged in the center; a filter drum for separating fibers and water is arranged in the fiber concentrator 222 .
[0052] The hydraulic disintegrator 201, the pulp storage tank 202, the refiner 203, the pulp tank 204, the material box 205, the mixing tank 206 and the sand remover 207 are connected in sequence, and the pulp outlet of the sand remover 207 is connected with the cage 211, and the net Cage 210 is arranged in net cage 211, as figure 2 As shown, the felt 209 is ...
Embodiment 3
[0060] In this embodiment, the equipment in Embodiment 2 is further improved, wherein a working pool 226 is added, and the working pool 226 is connected to the pulping pool through a slurry pump, and the slurry in the working pool is transported to the pulping pool ; At the same time, if image 3 As shown, the feed box 205 includes a sealed casing, a feed pipe 212, a feed pipe 213, a return pipe 214, a first branch pipe 215 and a second branch pipe 217; Slurry outlet; the feed port is connected to the slurry tank 204 through the feed pipe 212, the feed port is connected to the mixing tank 206 through the feed pipe 213, and the residual pulp outlet is connected to the working pool 226 through the return pipe 214; the feed pipe 213 A first control valve 216 is provided, and the first control valve 216 is located near the box; the second branch pipe 217 is arranged upstream of the first control valve 216, and the feeding pipe 213 is connected with the return pipe through the seco...
