The silt enters the crushing chamber from the silt entry, strikes and washes silt through the water spout, then along with broken breakage and the conveying that arrives, when with the silt basic fragmentation, transfers the harmful element in the silt to the water through the water, then removes the stone block filtering in the silt through removing the stone net.
Then enter into the hack mud room, through the meshing of hack mud internal tooth and hack mud external tooth, refine the broken more of silt to the contact of silt and water is more complete, through the rotation of rotation axis, the hack mud internal tooth has not only realized refining the fragmentation of silt, has still realized the stirring simultaneously, with silt and water more abundant contact.
Then the mixture enters into separator through curved export and puts into the material pipeline, separator puts into material pipeline upper portion and has seted up the opening, silt flows into the outside of pan feeding pipeline through this opening, and the inner wall of rotatory inner tube is at rotatory in-process, shovels into rotatory inner tube with silt because the existence of inner wall mud scraper, through the rotation of rotatory inner tube, grind mud into rectangular form on the outer wall, and water wherein is through the through-hole of outer wall in by centrifugal separation to rotatory urceolus, because the position that the discharge gate set up, mud can be full circle on the inner and outer wall, realized the recovery of mud as far as possible and fully extruded to moisture, then mud is discharged to rotatory urceolus through the discharge gate blocking of inner tube, and rotatory urceolus passes through the rotation of outer wall, with the water centrifugation to the water storage section of thick bamboo once more and remain blocking mud wherein.
The water body is discharged into the aeration chamber through the water outlet of the water storage barrel in real time, and after the water body rotates for a certain time, the rotating outer barrel stops rotating, and mud blocks in the water body are discharged into the dry mud treatment chamber.
In the mud processing chamber through the oblique in-process that transports mud downwards, from upwards jetting is hot-blast down, and hot-blast not only plays the effect of drying mud, but also wherein the volatile material heating of dissolving in wet mud volatilizees simultaneously to further pure mud, store for use through the holding vessel at last.
And the water body enters the aeration chamber, solid particles in the water body are adsorbed on the surface of bubbles through the bubbles blown out from the aeration port at the bottom to float upwards to form foams, the foams are blown into the foam outlet by the high-pressure nozzle and are crushed by the foam pressing part, gas generated in the aeration chamber is discharged from the gas outlet, and the purified water body enters the filter chamber and is discharged after being adsorbed by multiple filtration.
