Treatment apparatus using a rotary screen for waste soil which is contained in construction waste

摘要

This devise is invented as construction waste generated during the process in order to promote the efficient recycling of construction waste First, in processing the earth and sand, earth and sand to be screened in the course of the import process the construction waste in the hopper (1), and the water immersion tank quantitatively appointed separation width of the interior by supplying air injection nozzle 140 and the upper stirring to 100 the device is adapted to be stirring and aeration is done simultaneously by the wings (110), where the bark to emerge to the surface of the water supply, foreign materials such as Styrofoam is a sloping house overflow reservoir along the outside of the upper house water pipe (130) emission device configured such that, in the second stage is conveyed by the inner slope of the rotary screen; number and from the sand particles and clay and silt particles are removed, the earth and sand in the mixture of water includes a first rotary screen along the lower pipe (150) is supplied to the (200), a first filtration wall is configured in the rotary screen 240 is configured for 0.3 mm chemang; and sand (2) and earth and sand and silt that is submerged in the particle size of the clay boundary 4 is made quick dispersal As the glass particles, such as silt and clay particles are attached to the sand as the rotation step of the filtering wall so as to be separated by filtration exhaust; Then, the filtered silt and clay particles of glass and water is discharged mixed slurry (3) in a secure cover 230 is configured to be mounted to a screen outside into the water collecting tank; And a step in which the sand particles are discharged in a lateral direction by the inner screw 260; and install the sprinkler system (250) to the lower surface of the ceiling cover in order to prevent clogging of the filtering walls (240) to the outer wall surface of the rotary screen filter cleaning and configured to prevent the filtering net to remove foreign matter and phase; And, the discharged clay, silt, water soul is unified collecting the slurry (3) of the state in the tank 280 is transported in a second stage rotary screen 300 by the transfer pipe (270); construction and operation to be , and the second operation, as the configuration and operation of the first rotary screen in the rotary screen, just transfer the slurry (3) from 1 to filtering wall consisting of a mesh of the filter cloth or less 30 (340) a second rotary screen (300 having a air injection device 350 for preventing the clogging of the filter cloth so that the water network as a discharge by the high-speed rotation of a), the installation is operating. Further, the solid content comprising the steps of: a lateral outlet for automatic release by the inner screw 360; providing a construction waste treatment apparatus using the rotary screen sediment which comprises a system for separating the sand and clay in the earth and sand produced by relates. ; The present invention having the configuration described above is easy for the particles to sediment separated physically and has the advantage to allow separate recovery of sand and clay of good quality, the recovered sand separation in the sand for concrete can be used, and various clay pottery, wall directness environmental materials, clay bricks, it is possible to use such material for the main materials such as concrete and added.
