Description

Residual soil secondary filter-pressing dewatering device

Technical Field

The invention relates to the technical field of muck processing, in particular to a secondary filter pressing and dewatering device for muck residual mud.

Background

The residue soil is only one kind of construction waste. According to the municipal construction waste management regulation, the construction waste refers to the waste soil, waste materials and other wastes generated in the process of building, rebuilding, expanding and dismantling various buildings, structures, pipe networks and the like of construction units and house decoration and finishing of residents.

At present, more and more building muck is produced in engineering construction. In order to solve the problem of disposing a large amount of muck, an industrialized large-scale disposal method and rapid stirring equipment are needed. The stirring equipment needs to be capable of meeting the rapid stirring of a large-capacity stirring pot, and meanwhile, the influence of hard objects such as stones on the stirring equipment needs to be well treated. At present, the solidified slurry is sprayed into residual soil and mud by a high-pressure rotary spraying pile, and then cutting and stirring are carried out. The water content of the residue soil after the treatment is more than 30-50%. If the residual soil of the residue soil is directly put into a curing tank for curing, the preset strength can be achieved. When the solidified soil is crushed again to be used as filling materials after solidification, the external skeleton of the solidified soil is damaged after crushing, water in the solidified soil comes out, and the soil is changed into residual sludge soil without strength again, so that after stirring, secondary filter pressing equipment is used for removing water, the water content of the solidified soil is reduced to be below 30%, and the solidified soil still has high strength after secondary crushing; when using the clamp plate to compress dregs, the dregs on upper strata are easy to be compacted, block that clamp plate downstream compresses dregs, but the extrusion force that the dregs on lower floor received is little not the compaction, and the water absorption that the part was extruded leads to the dregs water content of lower floor too much in the dregs of lower floor.

Therefore, it is necessary to provide a new secondary filter pressing and dewatering device for residual soil and residual mud to solve the above technical problems.
