Description

Apparatus for producing concrete of dry type and wet type}

The present invention relates to a dry and wet combined concrete manufacturing apparatus, and more particularly to manufacturing concrete acting as a formwork to the outside using a dry method, and then to the inside of the fine sludge or construction waste generated while cutting the stone By using the wet method used, dry and wet concrete can be manufactured with a single device, and waste and discarded waste can be recycled to produce dry and wet concrete for manufacturing high strength concrete for construction or civil engineering materials. Relates to a device.

In general, in a stone factory or the like, which cuts the raw stone in order to use it as a useful construction material, a large amount of waste stone waste such as sludge is generated when the raw stone is cut, and the sludge is used to cut the stone. It is mixed with water.

Therefore, the sludge of the fine stone powder generated as described above is recycled in various ways, but the amount of demand is insignificant compared to the supply amount.

A large amount of sludge, which is not recycled, is chemically treated to separate it from water and is mixed with martha soil, which is illegally buried in mountains or riverside hills.

The mixture thus embedded adversely affects the natural environment by chemicals for separating sludge and water, and is a major cause of environmental damage.

For example, it is often used to produce concrete using the wet method, but due to the mixing of fine sludge and water, it takes considerable time to cure, so it is not very efficient.

Therefore, the concrete can be manufactured by the wet method using the sludge, and a new concrete manufacturing apparatus that uses a dry method regardless of time to cure concrete needs to be implemented, and the environment due to the sludge that is almost entirely disposed of There is an urgent need for a concrete manufacturing apparatus to solve the problem.

Therefore, an object according to the present invention for solving the problems as described above, by manufacturing a concrete acting as a formwork to the outside using a dry method, and then inside the fine sludge or cutting stone construction generated while cutting stones Dry and wet concrete can be manufactured with a single device by using a wet method using waste, and dry and wet concrete manufacturing apparatus for manufacturing high-strength concrete for construction and civil engineering materials by recycling wastes discarded in buried land Is in providing.

Dry and wet combined concrete manufacturing apparatus according to the present invention for achieving the above object, in the dry and wet mixed concrete manufacturing apparatus for manufacturing concrete for construction or civil materials using dry and wet, the dry stone powder Or sand or sludge hopper 10 for storing sand and for storing the wet sludge as necessary; Gravel hopper 20 for storing gravel; A load cell meter 30 for measuring the weight of the sand or sludge and gravel; A water hopper 40 for measuring and supplying an amount of water to be supplied; A cement hopper 50 for measuring and supplying an amount of cement supplied from the cement silo 52; Mixing any one of stone powder or a mixture of sand and gravel or a mixture of sludge and gravel supplied from the load cell meter 30 with water supplied from the water hopper 40 and cement supplied from the cement hopper 50 Two braid mixer 60; A mortar injector 70 into which a mixture of concrete mixed in the two braid mixer 60 is input; And a vibration table 80 which vibrates so that the filling rate of the mixture introduced into the mortar injector 70 is high.
