The organic content of ditch mud is lower, and inorganic components is generally far more than odor component.Inorganic components is very complicated, and except sandstone, the fragment of plastics, rubber, fabric, glass and metal etc. is also very common, and organic often sticking to above the particularly agglomerating plastics bag of these inorganic componentss, the rag etc. distributed deleterious foul gas after rotting.
Existing ditch mud treatment facility is eluriated ditch mud and separate separate treatment, and its required equipment volume is big, equipment cost is high, and low to the processing efficiency of mud.
Summary of the invention
To the problems referred to above, the invention provides sewer sludge elutriation and separation machine, its can accomplish simultaneously to the elutriation of mud with separate, equipment cost is low, and is high to the processing efficiency of ditch mud.
Its technical scheme is such: it comprises frame; It is characterized in that: said frame upper surface is equipped with flase floor; The below of flase floor is equipped with hydraulic propeller; The direction of propulsion of said hydraulic propeller is towards the ditch mud that falls from said flase floor, and the direction of propulsion of said hydraulic propeller is towards the release surface of rotation grid mechanism, and the discharge port of said rotation grid mechanism connects the import of suspended substance treatment unit; The bottom of said frame has the sandstone discharge port; Said sandstone discharge port is communicated with the feed end of worm conveyor, and the discharge end of said worm conveyor connects the import of sandstone treatment unit, and the middle and lower part away from a side of hydraulic propeller of said frame has sludge outlet.
It is further characterized in that: the bottom surface of said frame is the V-type bottom surface, and said sandstone discharge port is positioned at the bottom of said V-type bottom surface;
Said sludge outlet is positioned at the sidewall of said frame away from an end of said hydraulic propeller position, and relative position is positioned at the middle and lower part of said V-type bottom surface;
Said hydraulic assist(ance) device comprises blade, transmission shaft, reduction box, motor; Said motor output end connects the input terminus of said reduction box; The output terminal of said reduction box connects the input terminus of said transmission shaft, and said blade is set in the output terminal of said transmission shaft, and said blade is positioned at the internal cavity of said frame; Said reduction box, motor are positioned at the outside of said frame, and said transmission shaft is supported on a side sidewall of said frame through sealing cover, bearing;
Said rotation grid mechanism comprises drive-motor, rotation axis, release surface, housing; Said release surface is specially closed rake tooth chain; Said closed rake tooth chain is set on the transmission shaft; Said transmission shaft connects said drive-motor, and it is peripheral and do not block said closed rake tooth chain and contact surface ditch mud that said housing is set in said closed rake tooth chain, and the top of said housing exposes to the upper surface of said frame; Said lower part of frame is goed deep into the inside cavity of said frame, and the upper end of said housing has discharge port down;
Said worm conveyor comprises driving motor, screw shaft, shell; Said outer cover suit is outside in said screw shaft; Said driving motor connects said screw shaft; The feed end of said worm conveyor specifically be positioned at said lower part of frame be positioned at said sandstone discharge port under the position, the discharge end of said worm conveyor is specially the discharging port that open the upper end of said housing down;
Said frame has oil outlet away from the top of the sidewall of an end of said hydraulic propeller position.
After adopting structure of the present invention, need carry out ditch mud and eluriate when separating, will fall in the flase floor upper surface through mud; Sieving of flase floor oversize material and silt particle, mud and fritter sandstone get into the internal cavity of frame through flase floor, behind thin up; Form the plug-flow effect through hydraulic propeller, create flow action simultaneously, make water in the ditch mud, mud, suspended substance, sandstone etc. be dispersed in the together aspect of water owing to the difference of proportion; Thereby reach isolating purpose, sandstone is because the proportion die is sunken to the bottom of frame, because the frame bottom has the sandstone discharge port; The sandstone discharge port is communicated with the feed end of worm conveyor, and the discharge end of worm conveyor connects the import of sandstone treatment unit, so can sandstone at first be separated; Remaining water, mud, suspended substance enter into the release surface of rotation grid mechanism under the pushing effect of hydraulic propeller; Water, mud directly pass the release surface of rotation grid mechanism, and solid sundries such as suspended substance are attracted to release surface, are transported to discharge port along with rotation grid motion of mechanism; Be connected to the suspended substance treatment unit; Completion is to the separation of suspended substance, and the water, mud that passes the release surface of rotation grid mechanism flows out from the sludge outlet away from the middle and lower part of a side of hydraulic propeller of frame, separates thereby accomplish ditch mud eluriated.
In sum, structure of the present invention can accomplish simultaneously to the elutriation of mud with separate, equipment cost is low, and is high to the processing efficiency of ditch mud.
