Pump 7 is installed between leachate collection slot 5.
Further, the spray head includes hollow pedestal 21, and 21 lower end of pedestal is connected with back-shaped bracket 22, described
Back-shaped bracket 22 is provided with the shaft 28 towards pedestal 21, and the shaft 28 and the axis of pedestal 21 are parallel to each other, the shaft
It is arranged with rotor 27 outside 28, the rotor 27 is arranged with multiple rotations for driving rotor 27 to rotate close to one section of pedestal 21
Blade 23, one section far from pedestal 21 of the rotor 27 be arranged with it is multiple for colliding the collision blades 24 of lateral liquid, it is described
Liquid separation cone 29 is provided in pedestal 21, the circular cone lower peripheral of the liquid separation cone 29 is provided at least one waist hole, the rotation
Blade 23 is directly to connect with the percolate sprayed vertically around 27 axle center annular array of rotor, a side of the moving blade 23
The arc concave curved surface of touching, another side of the moving blade 23 does not contact directly with the percolate sprayed vertically, described to touch
Blade 24 is hit around 27 axle center annular array of rotor, each collision blade 24 is vertically arranged, the collision blade 24 be located at collision
Gap alignment between the adjacent rotated blade 23 of 24 top of blade, 28 sets of the shaft are provided with for preventing rotor 27 from rotating
27 locking plate 26 of rotor of backward dislocation, 27 locking plate 26 of rotor are fixed in shaft 28 by bolt 25.
Percolate penetrates pedestal 21, is directly injected on moving blade 23, moving blade 23 can freely revolve in shaft 28
Turning, the side of moving blade 23 is arc groove, and the percolate ejected from pedestal 21 is directly contacted with arc groove, though
The other side of right moving blade 23 is also arc-shaped curved surface, but the other side of moving blade 23 does not contact directly with percolate, from
The percolate that pedestal 21 ejects does not have a strong effect the other side of moving blade 23, is ejected on moving blade 23 vertically
Percolate generates the component of a transverse direction to 23 arc groove of moving blade, and moving blade 23 is made to generate becoming for a transverse shifting
Gesture, in the moving blade 23 that the upper section of rotor 27 is arranged along 28 axle center annular array of shaft, each moving blade 23 is in percolate
