| titleOfInvention | The remaking sand manufacture system which uses the waste |
| abstract | The present invention relates to an apparatus for producing recycled sand using construction waste.n n n The present invention for this purpose, the primary crusher 20a for primary crushing the construction waste supplied through the conveyor belt to the size of 40 ~ 100mm, and the secondary crusher (20b) for secondary crushing and sorting it again to 6 ~ 40mm And a first processing part sequentially provided with a first screen 31a and a third screen crusher 20c and a second screen 31b that crush and sort the construction waste discharged to the secondary crusher to 6 mm or less. (One); A second processing part (2) provided with a quaternary crusher (20d) and a third screen (31c) for crushing and selecting the waste foundry sand and the waste cast steel that are supplied to one side through a conveyor belt to 6 mm or less; At the lower end of the first and second processing parts 1, 2, a spiral feed blade 44c is provided on the inner circumferential surface of the upper end of the pedestal 41, and the groove 43a is provided at both ends of the outer surface so that the projection is fitted. At the same time, one side outer circumferential surface is formed with a cylinder 43 having a sprocket wheel 43b integrally formed thereon, and a motor 44 provided on one side of the pedestal 41 to drive a chain wound around the sprocket wheel, and the pedestal ( 41 is provided at one side of the upper end, and a hopper 42 having an extension plate 42a at a lower portion so as to easily supply construction waste, waste foundry sand, and waste cast steel to the inside of the cylinder, and near the inlet of the cylinder 43. And a mixer 40 having a spray nozzle 45 for ejecting hydrochloric acid stored in the tank 46 into the cylinder.n n n The present invention configured as described above is intended to produce recycled sand such as natural sand using only various wastes such as construction waste, waste foundry sand, waste cast steel and coal ash and briquette ash without using any natural sand. Is clean, strong, durable, and has a proper particle size, does not contain organic impurities and salt, and the products produced by the above-mentioned devices can be reused as various construction materials such as mortar, asphalt filling sand, and filling pipe filling filler. As a result of the test of the compressive strength, durability, water absorption, thermal conductivity, adhesive strength and freeze-thawing of the bricks produced from the reclaimed sand, the reclaimed sand was neutral and weakly alkaline. Have been found to be safe, and the resulting product And let the consumers will have to be able to significantly improve the reliability of the product. |
