DEVICE AND METHOD OF MANUFACTURING SOIL CEMENT FOR RESTORING WASTED QUARRY

摘要

The present invention relates to a device and a method for manufacturing soil cement that is used to restore, into the original shape, a region having topographical damage, such as a quarry, and to a device and a method for manufacturing soil cement that is used in a wasted quarry, wherein the device comprises: a sludge hopper having a stirrer; a screw conveyor which conveys discharged sludge from said sludge hopper; a stabilizer tank which provides stabilizers for said sludge; a solidifier silo which provides a solidifier in order to solidify a mixture in which said sludge and the stabilizers are mixed; a mixer which mixes, crushes, and stirs the mixture of said sludge mixture and the solidifier; a ferrous sulfate tank and a deodorant tank, which are neutralizers provided to neutralize and deodorize the mixture of said mixer; an air compressor which provides air to the solidifier silo in order to smoothly convey powder of said solidifier; and a deodorizer which collects and deodorizes odors created in the mixing step of said mixer. Further, the method comprises the steps of: storing a solidifier; storing sewage, waste water, and processed sludge; stirring the sludge; mixing the sludge with stabilizers; conveying the mixture of said sludge; providing air to the solidifier; conveying the solidifier; mixing the solidifier; mixing and crushing the mixture of the mixed solidifier and the sludge; providing neutralizers and a deodorizer to the mixture of the mixed solidifier and the mixed sludge; and collecting and deodorizing odors created in the mixing step of said mixture.
