Description
The utility model belongs to refining magnesium industry equipment, particularly relates to the vaccum-pumping equipment of production of magnesium by pidgeonprocess.
The current refining in China mainly adopted Pidgeon process in the magnesium industry, because this method technology is simple, industrial scale is flexible, grasp easily, and the speed of founding the factory is fast, and advantages such as the no three wastes so developed rapidly in China, are still constantly being built Xin Chang at present.Current in Pi Jiang remittance method refining magnesium, crux equipment is exactly oil-sealed rotary pump.The sliding formula Roots vaccum pump associating unit that cuts down of general employing, find that in life-time service mechanical pump has following shortcoming: (1) discharges a large amount of dust in refining magnesium and the water vapor dust enters the pump housing with air-flow, cause the oil-sealed rotary pump oil floatization, cause pump housing inner rotatable part to scratch or not working. degradation, life-span is short, unstable properties; (2) the oil-sealed rotary pump maintenance load is big, and maintenance difficulty is higher, and maintenance cost is big, and every month mechanical pump maintenance cost of a medium-sized refining magnesium factory is about 150,000 yuan; (3) the mechanical pump pumping speed is low, and pre-evacuated time is long, and the general atmosphere pressure is evacuated to the required vacuum tightness of reduction reaction, and (13.3～1.33Pa) need 2-3 hour, the length of finding time in advance can influence the primary crystallization state of MAGNESIUM METAL, prolongs the reduction reaction time, reduce output, energy consumption is big, the expense height; (4) investment is big, and every cover mechanical pump unit can only satisfy 8-9 refining magnesium cylinder, and a large-scale refining magnesium enterprise just needs many mechanical pump units, forms aerial fleet, and investment greatly.
The purpose of this utility model is: adopt the jetting stream vacuum equipment that does not have rotatable parts, significantly reduce maintenance cost, increase the service life, improve pumpage, shorten and find time in advance and the reduction reaction time, improve output, reduce investment outlay.
The utility model is real like this: a kind of refining magnesium jetting stream vacuum equipment, this equipment comprises by nozzle, mixing section, the jet evacuation that scatterer constitutes, condenser, pipeline, valve, the pond is formed, feature of the present utility model is: the bleeding point of first step jet draws air device 1 is connected with the extraction pipe of magnesium metallurgy pot, second, three grades of jet evacuation 2,3 bleeding point links to each other with the air outlet of upper level jet evacuation respectively, the bleeding point of fourth stage jet evacuation 4 connects on the condenser 7 all, its underpart is connected with the air outlet of third stage jet evacuation 3, the bleeding point of level V jet evacuation 5 connects condenser 8 tops, its underpart is connected condenser 7 with fourth stage jet evacuation air outlet, 8 lower pipeline insert in the tank water.
The bleeding point of jet evacuation 6 is by pipeline and check valve, with condenser 7, or is connected with condenser 8 tops.
The nozzle throat pipe diameter is Φ 1.5～Φ 15, tapering K:1: 2.7～1: 5, and K4:1: 1～～1: 1.5, diffuser throat Φ 10～Φ 200, tapering K2:1: 8～1: 13, K3:1: 8～1: 10.
The nozzle inlet mouth of each jet evacuation is connected with vapour pipe, and condenser top links to each other with water pipe.
Enforcement of the present utility model will produce following advantage, because jetting stream vacuum equipment does not have rotatable parts, dusty gas and water vapor can not work the mischief to equipment, significantly reduce frequency of maintenance, save a large amount of maintenance costs, and the life-span is long, save investment.The speed of finding time is more faster than mechanical pump, shortens the production cycle, improves output, and power can design according to customer requirements, relatively flexibly.Invest lessly, running expense is low, and saves energy is remarkable.A general jetting stream vacuum equipment can replace 10 groups of (2 every group) oil-sealed rotary pumps, saves investment hundreds of thousands of unit.
