Description
Technical field
The utility model relates to a kind of artificial mechanism sand equipment processed, relates in particular to a kind of device that is sieved out qualified sand grains and also stone flour is separated shedding by air force air-flow simultaneously.
Background technology
Along with the demand of expanding economy and engineering construction; the mixed earth of commodity is more and more higher to sand quality requirement on the one hand, and consumption is increasing, and on the other hand due to the raising to environmental protection consciousness; the flood control of riverbed and dykes and dams is required to improve, and natural river sand exploitation is more and more restricted.
Traditional river sand resource is exhausted, and artificial sand making has become the main acquisition methods of sand in a lot of areas.Artificial sand making is exactly that natural building stones are carried out repeatedly broken and pulverized, and sieves sandstone with moto-vibro screen, the mud powder of sweeping along in sand will be separated and sloughs with the fine powder producing in crushing process simultaneously, makes its particle and grain size distribution reach building sand standard.Here shedding claims again desliming, selects powder.
There is at present shedding, wet method and the dry process of two kinds of techniques for artificial sand making.Conventional method is wet method water elution powder craft, and because the de-shedding technique of wet method is to the having relatively high expectations of water source and environment, development is restricted.Another kind method is exactly dry method shedding technique.Dry method shedding technique is by aerodynamic method, the stone flour in sand to be departed to sorting to go out.The defect of practical dry method shedding technique is throughput low (maximum 60t/h) at present, and shedding efficiency is low, and cost of investment is high.
Summary of the invention
The utility model technical issues that need to address have been to provide the sand use pair processed of a kind of artificial mechanism and have selected powder separator, utilize air force principle to filter out qualified sand grains in the process of shedding simultaneously, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises: dynamic powder concentrator and static powder separating machine; Dynamic powder concentrator connects by flange on the casing that is directly seated in static powder separating machine; Described dynamic powder concentrator comprises: transmission device, rotor, fixed guide vane, the first housing; Described fixed guide vane is to be fixed on the first housing by multi-disc annular, and described rotor is suspended by the bearing block in casing; Described rotor stretches out power transmission shaft above the first housing, and power transmission shaft is connected with the transmission device that is fixed on the first housing top by a shaft coupling; Described static powder separating machine comprises: the second housing, stepped plate, water conservancy diversion air grid, granularity control guiding mechanism and tilting plate lock air-valve; Described stepped plate is fixed on the inside of the second housing, and on the right side of described stepped plate, air inlet place is provided with water conservancy diversion air grid; At the nethermost granularity control guiding mechanism that is provided with of described stepped plate; Bottom exit position at described the second housing is provided with tilting plate lock air-valve.
Compared with prior art, the beneficial effects of the utility model are: can be to being applied to the stone flour that artificial dry method technology for making sand, construction waste reclaim or mud powder separates and sandstone efficiently separates, the stone flour or the mud powder that in raw material, are less than 0.075mm are separated, and separative efficiency can reach 95%; Product handling capacity 100t/h-440t/h, the ratio of performance to price is far away higher than existing production equipment.
