Abstract
The invention discloses a waste cement recovering method, which comprises the following steps of: adding 0.1-0.2 percent of retarding agent into water in a clean water tank and a precipitation tank; when a transport mixer is required to be cleaned, replenishing water from the clean water tank for washing the transport mixer, discharging wastes into a full-automatic waste concrete recovering device provided by the invention, and separating the wastes into sand, stones and slurry; producing raw materials of concrete by using sand and stones; and precipitating the slurry in the precipitation tank, completely draining clean water on the surface layer, and pumping precipitated gelled material slurry out for later use, wherein the gelled material slurry can be taken as a gelled material for preparing masonry and plastering mortar, and can be taken as a gelled material of an aerated concrete tile. The waste cement recovering method is simple and practical, and the aim of completely and fully automatically recovering waste concrete at the lowest cost and the lowest consumption by using the simplest device is fulfilled.
Description
Technical field:
The present invention relates to a kind of commerical ready-mixed concrete company, concrete mixing plant also not agglomerative discarded concrete reclaiming method and device thereof of being applicable to.
Background technology:
Gelling material in the discarded concrete does not also have sophisticated recovery method at present, and in order to overcome the above problems, I had announced once that a kind of application number was 2006101323693 " discarded concrete reclaiming method and device thereof "; Its method is that discarded concrete is sieved through the water flushing, and the sand of separating, masonry concentrate post precipitation to get rid of clear water pulp-water for producing concrete starting material again; This method in the gelling material slurry that reclaims, adds retardant again, and substitutes gelling material production concrete, though can be utilized gelling material in the 10%-20% ratio of binder total amount in the concrete; But in sedimentary process; Gelling material have the part gelling material also can surpass final setting time, and recovery method is complicated still in aquation; In order to address this problem, I provide following invention:
Summary of the invention:
One of the object of the invention provides a kind of discarded concrete reclaiming method: it can all be recycled the sand in the discarded concrete, stone, gelling material.
Realize that technical scheme of the present invention divided for three steps:
The first step: a full-automatic discarded concrete separating and reclaiming device is installed in the washing bay, clean water basin, two gelling material settling tanks, and add the 0.1%-0.2% retardant in the water in clean water basin and settling tank.
Second step: when truck with grout mixer and water tank needs carwash; The carwash that draws water in the clean water basin, and the waste discharge behind the carwash cleaned separation in full-automatic discarded concrete retrieving arrangement, with the sand of separating, masonry for producing concrete starting material; Pulp-water is discharged in the gelling material settling tank and precipitates; Treat the abundant post precipitation of gelling material, the clear water in the settling tank is discharged in the clean water basin, collect the gelling material slurry subsequent use again; This gelling material slurry can prepare masonry mortar and motar is used for building decoration engineering, also can be used as the gelling material of producing the gas concrete brick.
The 3rd step: in time in clean water basin and settling tank, replenish clear water, and press the water yield adding 0.1%-0.2% retardant that is replenished.
Through present method, can reclaim gelling material very simply, and realize the purpose that addresses the above problem.
Two of the object of the invention provides a kind of full-automatic discarded concrete retrieving arrangement:
