The stirrer gear axle on sandstone trap bag rectangle tank body top, the driving pulley that is connected with keyway by key with the tooth axle, V belt and motor that the band drive rotates, on sandstone rock catcher device, be provided with several and stir gear, and pass two long limit faces of rectangle tank body, with its movingly, every rooted tooth axle is provided with several teeth, a motor drives several tooth axles by belt and rotates, the upper end of rectangle tank body is uncovered, go to the bottom and be waveform, be provided with several sewage draining exits at the wave end with valve control, wide top at tank body respectively is provided with an import and discharging opening, is positioned between feed bin and the waterpower grass chopper or before the Water Extraction Machinery by the designed sandstone trap of technical scheme.
The high-efficiency dehydration conveyor screw is made up of spiral and U-lag, the U-shaped helicla flute is made as horizontal semi-circular groove, in the semicircle of groove, be provided with the U-shaped filter plate, the upper edge of filter plate and semicircular groove inner edge extruding or weld together, at the bottom of the U-shaped filter plate with at the bottom of the semi-circular groove at a distance of certain distance, be provided with outlet of sewer in the semi-circular groove bottom, spiral and helical axis are made as one, the axle two ends pass semi-circular groove the shrouding at two ends, with its movingly, the rotation of driven by motor spiral.
The part of the feeding serew material pipe of scroll feeder and T shape pipe junction and the part of scroll feeder shorten 100-150mm simultaneously, reduced the distance that forage enters feeding serew pipe track, reduce the charging resistance, improved slurrying output, reduced production cost.
The present invention is perfect paper mill wet process for pretreating raw material has reduced the wearing and tearing of equipment, has prolonged the service life of equipment, has improved utilization rate of equipment and installations, has reduced the slurrying cost, has obtained favorable economic benefit.

Five, specific embodiment
For further setting forth technical scheme of the present invention,, be described in detail by embodiment below in conjunction with Figure of description.
Shown in Figure of description 1, efficient wet process for pretreating raw material in the paper plant of the present invention production initiating process, its technical characterictic is that the grass of feed bin is delivered to sandstone trap 2 through feed bin conveyer belt 1, behind washing desanding or metal, sent to waterpower grass chopper 3 by the stirrer gear 15 (shown in Figure 2) of sandstone trap 2, the chopping washing is after helicoidal pump 12 is sent second level sandstone trap 10 to by feed-line 13, behind washing sand mud, be sent to 7 dehydrations of U-lag Water Extraction Machinery by the stirrer gear of second level sandstone trap 10, after the dehydration, sent to feed back spiral 5 by the spiral of U-lag Water Extraction Machinery 7, the grass that advances the feed back spiral advances 6 meterings of pin drum meter, remaining grass is through feed back pipe 4, the power of intaking again grass chopper chopping washing is again by above-mentioned flow process circulation one time.The grass of selling the metering of bulging meter advances high-efficiency dehydration conveyor screw 8, removes the laggard scroll feeder 9 of sewage, enters the paper pulp making technology of paper plant through the feeding serew pipe precession T of scroll feeder 9 the insides type pipe 11.
