DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a colored concrete material.

[0002]

2. Description of the Related Art Conventionally, pigments are mixed with concrete materials to produce colored concrete, and most of the pigments are in the form of powder. The powder pigment tends to cause uneven mixing, and the color is adjusted by adjusting the ratio, adding water, mixing and drying, and repeating the test to determine the desired color. On the other hand, the aqueous pigment can easily develop the color of the concrete material by blending the basic colors, but the blending has been determined manually. The basis for the preparation was mainly the measurement of the volume and weight of the pigment.

[0003]

SUMMARY OF THE INVENTION An aqueous pigment is used as a coloring material, and its blending ratio is set so as to have a desired color, and by automatically blending this, it is possible to reduce the need for manual labor. It is intended to obtain a concrete material having a uniform color tone without uneven coloring.

[0004]

According to the present invention, in mixing and mixing aqueous pigments of different basic colors in a mixing tank, the supply amounts of the aqueous pigments of the respective basic colors are determined based on a predetermined blending amount. Aqueous pigment is supplied into the mixing tank while automatically controlling according to the sensor's instructions determined in advance, and then uniformly stirred and mixed to form a coloring material, which is supplied to a concrete mixer and uniformly mixed with the concrete material A method for producing a colored concrete material. In the above, stirring and mixing of the aqueous pigment may be performed by air bubbles. When a coloring material having a different color tone is to be obtained, the inside of the mixing tank is washed and washed in advance to prepare a coloring material having a new color tone.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. In each figure, 1, 2, 3, and 4 are aqueous pigment tanks containing pigments of different basic colors, and each tank is provided with a supply pipe 9, 10, and an air pump 5, 6, 7, and 8. 11,1
2 are connected. Branch pipes 17, 1 having pneumatic valves 13, 14, 15, 16 are provided to the air pumps 5, 6, 7, 8.
Air is supplied through 8, 19 and 20. The ends of the feed pipes 9, 10, 11, 12 are connected to a manifold 21, and are connected to a water supply pipe 23 via a feed valve 22. The water supply pipe 23 has a water supply valve 24,
Further, it communicates with the mixing tank 27 via the branch pipe 25. 26
Is a branch pipe valve. In the upper part of the mixing tank 27, an outlet 30 of a water supply pipe 28 having a water valve 29 is opened,
A measuring sensor 31 faces, measures the liquid level in the mixing tank 27, and feeds back the result to the electric control panel 32 via the control wiring 33. The instruction according to the design amount of the control wiring 3
4, the air valve 13, 1 of the branch pipe for air supply
4, 15 and 16, and a predetermined air valve is opened to operate an air pump associated therewith. 35 is an air supply pipe having a valve 36. A discharge pipe 37 is provided at the lower part of the mixing tank 27.
And a valve 38 connected to a concrete mixer 39. Reference numeral 40 denotes a discharge valve.

An embodiment of the present invention will be described with reference to FIG. 2. First, as shown in FIG.
4 and the valve 26 are opened, and a small amount of water is put into the mixing tank 27 from the water supply pipe 23. Next, as shown in FIG. 3, the water supply valve 24 is closed, the aqueous pigment in the aqueous pigment tank 1 is opened, the pneumatic valve 13 is opened, and the air pump 5 is operated. Open and feed into mixing tank 27. At this time, the upper measurement sensor 31 senses the liquid level of the aqueous pigment in the mixing tank 27 by the measurement wave, and when the predetermined amount has been supplied, the different color aqueous pigment in the aqueous pigment tank 2 is removed as shown in FIG. It is fed into the mixing tank 27. Hereinafter, the same applies to the aqueous pigment tanks 3 and 4. However, depending on the desired color tone, the type of the aqueous pigment to be supplied is appropriately increased or decreased.

When the mixing of the aqueous pigment is completed, as shown in FIG. 5, the supply valve 22 and the valve 26 are closed, the valve 36 is opened, and air is supplied from the air supply pipe 35 into the mixing tank 27 so that the aqueous pigment is mixed. Is uniformly mixed with air bubbles. Next, as shown in FIG. 6, the uniformly mixed aqueous pigment is discharged into a concrete mixer 39 by opening a valve 38 through a discharge pipe 37 below the manifold 21. After completely draining, as shown in FIG. 7, cleaning water is supplied by opening a water valve 29 from a water supply pipe 28 mounted on the upper part of the mixing tank 27, to wash color stains in the tube, and to wash and drain. Opens the discharge valve 40 and discharges outside the apparatus.

[0008]

According to the present invention, when an aqueous pigment is mixed with a concrete material to be colored, several kinds of aqueous pigments of basic colors are automatically prepared based on a predetermined blending amount, thereby facilitating color matching. It can be performed uniformly. Therefore, it is possible to eliminate the adverse effects of color unevenness and color mixing as in the case of relying on manual labor.
