Because the shell in the extra large sand is difficult to get rid of, and causes extra large sand to be difficult to use in high-grade concrete, the extra large sand that shell content is high can't utilize, and causes the waste of resource.
Though China carries out coastal various places sea sand desalting much year, how to remove extra large sand shell less than mesh size, although some researchs and trial have been carried out in various places, but all there is bigger defective in the method for development, be difficult to use in production, China does not also search out reasonable treating method so far.
Through observing, find that the shell in the extra large sand generally occurs with the form of shell skin, in the form of sheets, and sand is bulk or class circle shape.Through repetition test, find that shell skin and extra large sand final settlement speed in Newtonian fluid have nothing in common with each other, how to utilize shell skin and the difference of extra large sand in the water field of flow, realize the device of shell skin and extra large sand separation, have to be solved.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned defective, and the shell scavenge unit in a kind of extra large sand is provided.
Scheme of the present utility model is: device is by vertically forming to flow-path tube, liner plate, sand inlet, sand export, collecting pit, the flow-path tube lower port is communicated with water source tube, the flow-path tube upper end is provided with the delivery port towards filtering ponds, and flow-path tube central tube inwall ring week is fixed the liner plate of a tilting densely covered pore; Flow-path tube is positioned at the high distolateral sand inlet that is provided with of liner plate, and flow-path tube is positioned at liner plate lower end opening and is provided with sand export, and sand export is communicated with collecting pit, and collecting pit upper storage reservoir mouth is higher than the flow-path tube delivery port.
Advantage of the present utility model is: shell and sand separate and belong to non-homogeneous mixture and separate, continuous phase in the heterogeneous system and decentralized photo do not have the different physical property of tradition (as density etc.), but both shape differences, sand are bulk or class circle shape, and shell is flakey.The shape of solid particle has considerable influence to terminal velocity, in similar particle, is maximum with the terminal velocity of spheric granules, and the terminal velocity of other irregularly shaped particles is then corresponding less.This is because the big cause of the resistance coefficient of irregularly shaped particles ratio spherical grain resistance coefficient.Lepidiod shell is big than the sand resistance coefficient of bulk and class circle shape, different final settlement speed is arranged in the Newtonian fluid field of force, the utility model is artificially made the Newtonian fluid field, makes between decentralized photo (shell) and the continuous phase (extra large sand) relative motion takes place, and then both is separated.
