when the household garbage is pretreated by the procedures of pulping and the like, the mixed material is fed into the rotary screen 2 at one time through the feed inlet 211, water is filled in the box 7, as the included angle between the screen 21 and the horizontal plane along the advancing direction of the material is 5-15 degrees, 1/2-2/3 part of the length of the screen 21 can be immersed into the water of the box 7, the bottom of more than half of the length of the screen 21 is ensured to be positioned below the water surface from the feed end, the discharge end is not positioned in the water, thus, along with the rotation of the rotary screen 2, the mixed material continuously advances under the action of the spiral guide plate 23 and is contacted with the water for a long distance, the mixed material is sufficiently cleaned and dispersed under the action of the water, so that small-particle inorganic matters such as pulp and sediment in the mixed material flow out through the screen slot of the rotary screen 2 and enter the box 7, the pulp in the box 7 can be suspended on the water surface, the pulp is discharged through the water outlet 72 at the side end of the box 7 to obtain the pulp (the discharged pulp can be further refined and separated through the extractor), and the inorganic particles such as sediment can fall into the bottom of the box 7 through the refined sediment discharge outlet 71; the rest mixed material containing plastic is discharged in the rotary screen 2 along with the action of the spiral guide plate 23 to the discharge hole 212, so that the plastic, paper pulp and inorganic matters in the mixed material pretreated by the procedures of pulping and the like can be fully separated at one time through the equipment, and paper and low-value renewable resources of the plastic which cannot be directly utilized in household garbage are separated, thereby improving the recycling utilization rate.
Compared with the prior art that a plurality of devices and a complex process are adopted to realize the separation process of paper pulp, inorganic matters and plastic materials, the invention can realize the separation of different components of paper pulp, inorganic matters and plastic in garbage by only one device through the functions of hydraulic power, screening, sedimentation and the like, greatly simplifies the treatment process, improves the treatment efficiency of household garbage, and has small occupied space of one device, thereby obviously reducing the treatment cost of the household garbage.
Finally, it should be noted that the above embodiments are only for illustrating the technical solution of the present invention, and not for limiting the scope of the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made to the technical solution of the present invention without departing from the spirit and scope of the technical solution of the present invention.
