Description
Technical field
The utility model relates to chemical field, particularly a kind of aluminum oxide decomposer agitator.
Background technology
Seed decomposable process is critical process particularly important in process for making alumina, and decomposer is the special mixing plant that seed decomposes workshop.Domestic each the large alumina producer at present decomposer specification of maximum is 14 meters of diameters, 30～36 meters of height, and volume approximately 5000 sides, power of motor 75kw, speed of agitator is 4.5～5.0r/min approximately, and it is comparatively extensive that this is configured in current application, moves also more stable.But along with the increase of cost of investment, country is to energy-saving and cost-reducing promotion in recent years, each manufacturer all wishes can reduce investment and operating cost when reaching equal production capacity as far as possible, and this just facilitates specification of equipment to be tending towards large scale development.Except the tank diameters such as the desiliconization of large scale development, dilution, the maximization of decomposer has also caused in the industry to be paid attention to.Compared to the traditional design that keeps more than ten years, after equipment enlarging, cell body specification increases, and monomer volume increases, and number of devices reduces, and can save space, reduces soil occupation rate when production capacity is up to standard, and integrated cost reduces.Existing aluminium oxide producer and designing institute propose the preliminary imagination that decomposer maximizes a few days ago, cell body specification are set as to diameter 18m, highly about 36.5m, groove volume approximately 9000 sides.For this important breakthrough innovation on alumina industry agitator at home, how decomposer agitator is maximized, designing a kind of agitator energy-efficient, stable performance that adapts to the application of diameter 18m decomposer becomes the worth difficult problem of studying and capturing.Therefore, the improvement of aluminum oxide decomposer agitator is the problem of needing at present solution badly.
Summary of the invention
For above-mentioned situation, for solving the defect of prior art, the object of the utility model is just to provide a kind of aluminum oxide decomposer agitator, can effectively solve stirring efficiency and effect problem after existing aluminum oxide decomposer cell body increase, dilatation.
The technical scheme that the utility model solves is, comprise pedestal, motor, reductor and shaft, the cross beam at pedestal and cell body top is fixed together, reductor is through being bolted on pedestal, and reductor and motor link together, and reductor is connected with the shaft in cell body through shaft coupling, blade is equipped with on shaft top, lower blade is equipped with in bottom, and shaft lower end is contained on Limit Bearing, and Limit Bearing is contained on the gusset plate of cell body bottom.
The utility model reliable in structure, stable performance, integrated cost reduces, and saves energy consumption, is the innovation on agitator.
Accompanying drawing explanation
Fig. 1 is structural profile front view of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail.
By Fig. 1, provided, the utility model comprises pedestal, motor, reductor and shaft, pedestal 3 is fixed together with the cross beam at cell body 9 tops, reductor 2 is through being bolted on pedestal 3, and reductor 2 links together with motor 1, and reductor 2 is connected with the shaft 5 in cell body 9 through shaft coupling 4, blade 6 is equipped with on shaft 5 tops, lower blade 7 is equipped with in bottom, and shaft 5 lower ends are contained on Limit Bearing 8, and Limit Bearing 8 is contained on the gusset plate 10 of cell body 9 bottoms.
In order to guarantee result of use, described motor 1 is four-stage motor, and reductor 2 is the parallel-shaft bevel wheel reducer with reinforced bearing, and its speed ratio is 300～400, and service coefficient is more than or equal to 1.6.
Described upper blade 6 is 2～3 layers, and every layer of upper blade 6 is comprised of two symmetrical blades, 90 ° of cross-distribution of adjacent two layers, and the diameter of upper blade 6 is 0.5～0.65 times of cell body diameter, end of blade linear velocity is less than 4m/s.
Described lower blade 7 is comprised of two symmetrical blades, and lower blade 7 is 500～800mm apart from the height of cell body 9 bottoms, and diameter is 1.1～1.25 times of upper blade 6.
Service condition of the present utility model is that base bearing is welded on the gusset plate of cell body bottom, plays position-limiting action.Blade is two to three layers of upper blade, blade at the bottom of one deck, and every layer of blade is comprised of two symmetrical blades, 90 ° of cross-distribution of adjacent two layers.Upper diameter of propeller blade is 0.5～0.65 times of cell body diameter, in agitator running, the end of blade linear velocity of upper blade is less than 4m/s, avoid in alumina decomposition process, the nucleus of generation being smashed, end blade is 500～800mm from bottom land height, diameter is 1.1～1.25 times of upper blade, can effectively eliminate the buildup of bottom land surrounding, reduces the operation maintenance time.It is even that the utility model adopts major diameter, slow-revving scheme can reach material stirring, and the solid difference that contains is less than 5% up and down, and end of blade linear velocity is low, does not affect the object that nucleus forms, and meets the requirement of alumina decomposition operation to agitator.
