A LIME ELEMENT CLEARING METHOD OF REVIVAL AGGREGATE MAKE USE OF CARBONIC ACID GAS AND
THAT EQUPMENT
Technical Field
[1] The present invention relates to a removing device a lime ingredient from a circulation aggregate by neutralizing alkali cleansing water after supplying carbonic acid gas to the cleansing water, and more particularly, to a lime ingredient removing device using a carbonic acid gas from a circulation aggregate and a method thereof to be used in a freezing day by supplying hot water and by burning up a useless material using a boiler supplying carbonic acid gas with chemical freely. Simultaneously, to remove a lime ingredient from a circulation aggregate (wet production process, dry production process) by neutralizing the potential of hydrogen PH of recycle cleansing water by supplying carbonic acid gas to the cleansing water. Background Art
[2] Generally, a circulation aggregate is called as a recycled aggregate. It is produced to be reused by separating after crashing a disuse concrete or useless material.
[3] The raw materials of cement are a limestone and clay. They are obtained by putting in the fire in condition of 14000C after shattering in the weight ratio of 4: 1. The principal ingredient is an oxidation lime.
[4] The concrete is stuff for construction work or public work. After mixing thin aggregate and thick aggregate and cement and water, it becomes hard to be an inorganic matter. The cement of the concrete reacts to water and makes the oxidation lime to be a lime hydroxide, therefore the concrete shows alkali (pH 12-13).
[5] The circulation aggregate is produced by separating after crashing the crapped concrete. The main ingredients of the circulation aggregate are lime hydroxide and aggregate as the main ingredient of concrete. The circulation aggregate does not match the conditions of the superiority aggregate are density and absorption rate. Therefore, it can not be used for a construction aggregate, but is used for cheap stuff.
[6] However, if the hydroxide lime adhered to aggregate of the useless concrete got removed effective, the aggregate would be used for the construction aggregate as like natural aggregate. If the circulation aggregate can be used for the use of natural aggregate, the coefficient of utilization would be enlarged. The prior art for the circulation aggregate producing method produces the circulation aggregate by separating after crashing. This technique can produce enormous volume of the circulation aggregate. However, the removing of hydroxide lime from cement is not
accomplished effectively. So, it is not appropriate for the construction aggregate.
[7] The other method for producing circulation aggregate is washing in the processing of manufacturing the circulation aggregate via supplying cleaning water to remove hydroxide lime from cement. This technique does not dump the cleaning water but reuse after gathering in water tank. The water is strong alkali because it includes lime ingredient. Therefore, even though the increasing the number of washing times, the lime ingredient is not removed. Without reusing cleaning water is too expensive to produce the circulation aggregate.
[8] Methods for producing thee circulation aggregate are developed in America and
Japan. The first method is after heating the useless concrete to 3000C, and shocking to aggregate. The second method is filling aggregate to a sealed water tank, moisture percolating into recycled aggregate through the condition of vacuum and decompression. The third method is after inputting aggregate into a drum, and removing mortar attached to the surface of aggregate by rotating the drum. The other method is settling the useless aggregate to a water tank and blowing air drops at the lower part of the water tank, and separating aggregate from mortar using the density difference.

It is supplied to a pipe(24) from each valve(23) via a distributor (22).
[13] The carbonic acid gas distributed to the pipe(24) can neutralize the cleansing recycle water stored in a water tank(30) by ejection through many acid radical pipe(31) established at the inside of the water tank(30).
[14] The cleansing recycle water stored in the water tank(30) is gathered after cleansing
the circulation aggregate. There are 1.5g hydroxide limes per 1 liter in the cleansing water. It shows strong alkali (pH 12-13). When the carbonic gas is ejected through the acid radical pipe, the insoluble carbonic acid lime is produced by reaction between the hydroxide lime and carbonic acid gas. Therefore the cleansing water is changed from alkali cleansing water to neutral cleansing water. It is shown in chemical equations 1 and 2 as below.
[15] [Chemical equation 1 ]
[16] C + O2 → CO2
[17] [Chemical equation 2]
[18] Ca(OH)2 + CO2 → CaCO3 + H2O

(43) are connected to the water supplying pipe (32). There are many ejection holes (46) with regular intervals at the lower part through the connecting hole (44) at the ejection pipe (43). The water ejection device (41) ejects the cleansing recycle water toward the circulation aggregate supplied to the mesh (42).
[24] The cleansing recycle water supplied through the ejection hole (46) of the water ejection device (41) can removes lime ingredient. The cleansing recycle water is supplied as cleansing water including carbonic acid gas and neutralized at the water tank (30).
[25] The lime ingredient is removed via the ejection cleansing device (40). The circulation aggregate is supplied to the blending cleansing device (60). The blending cleansing device (60) has supplying device (61) and supplies circulation aggregate to a hoper (62) and tank (64).
[26] The recycle cleansing water is supplied to the tank (64). Many blending wings (65) established at a rotation axis (63) blend the circulation aggregate in sink under water and remove lime ingredient from the circulation aggregate.
Advantageous Effects
