Described upper strata blade and the angle of oar axle are 60 degree.
Described upper strata blade and the angle of oar axle adjustable.
The efficient low sheraing type circular arc blade of described lower floor's blade to be cross section be circular arc, upper strata blade is also for cross section is the efficient low sheraing type circular arc blade of circular arc or common blade.
A limit of described circular arc blade is straight flange, and another limit extends to blade length 1/4 be oppositely contracted to blade tip width gradually again from outside 45 degree of root of blade.
Height and the opening for feed center, extraction pipe 5 inclined-plane of described lower floor's blade blade tip lower end are contour.
All be provided with between every sheet blade of described lower floor's blade and oar axle increase blade strength effect and can with the pivotal strut member 7 of blade synchronization.
All be provided with between every sheet blade of described upper strata blade and oar axle increase blade strength effect and can with the pivotal diagonal brace 8 of blade synchronization.
The described position of diagonal brace 8 on oar axle is adjustable.
The beneficial effects of the utility model:
The utility model, by reducing extraction pipe from bottom land height to 0.8-1.2 rice, can reduce slip deposition probability, thus can reduce the blade number of plies, and the final power of motor that reduces, to 45KW, realizes energy-conservation object.
Upper strata of the present utility model blade becomes 60 degree to arrange with oar axle, lower floor's blade for being horizontally disposed with, can realize stirring in groove evenly, realize admittedly up and down in groove being less than 5% containing difference.
Blade of the present utility model adopts HDHSG efficient low sheraing type circular arc blade to ensure crystallization effect, avoids being smashed by the nucleus of generation in alumina decomposition process, reduces resistance simultaneously, more energy-conservation.

Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
As Figure 1-5.
A kind of energy-saving aluminum oxide decomposer, it comprises cell body 1, motor 2, oar axle 3, blade 4 and extraction pipe 5, motor 2 is arranged on the cover plate of cell body 1, oar axle 3 is directly or indirectly connected with the output shaft of motor 2 and stretches in cell body 1, blade 4 is arranged on oar axle 3, extraction pipe 5 is arranged in cell body 1 and close cell body inside edge, the lower end of extraction pipe 5 is as feed end, upper end is connected with the upflow tube 6 stretched out outside cell body 1, as shown in Figure 1, described extraction pipe 5 is 0.8-1.2 rice so that reduce slip deposition probability apart from the distance of cell body 1 inside bottom surface; Described blade 4 is by one deck lower floor blade and at least one deck upper-layer paddle leaf forms (is two layers of upper strata blade in Fig. 1, the upper strata blade of one deck or more than two layers can be set according to the height of cell body during concrete enforcement, the present embodiment is illustrated for two layers of upper strata blade), Fig. 1 is visible, and height and the opening for feed center, extraction pipe 5 inclined-plane of lower floor's blade blade tip lower end of the present utility model are contour.Described upper strata blade and the angle of oar axle are 50-70 degree, optimum angle is 60 degree, during concrete enforcement, the angle of upper strata blade and oar axle 3 also can be designed to adjustable structure, by transferring the position of diagonal brace 8 on oar axle 3 of playing increase upper strata blade strength to realize the adjustment of angle.Lower floor's blade of the present embodiment is horizontally disposed with, during concrete enforcement, every sheet blade of lower floor's blade also can install one rise gain in strength and can with blade synchronization pivotal strut member 7(Fig. 1), between the blade layer of upper strata and the blade line of upper strata blade layer and lower floor's blade layer each other all in being arranged vertically, as shown in Figure 2, the number of blade of every layer of blade layer (comprising upper strata blade layer and lower floor's blade layer) is 2 and is a straight line.In order to raise the efficiency, reduce the probability that blade smashes nucleus, the utility model has carried out particular design to lower floor's blade, as shown in Fig. 3,4,5, the efficient low sheraing circular arc blade (HDHSG) of lower floor's blade to be cross section be circular arc (Fig. 4), a limit of described circular arc blade is straight flange, and another limit extends to blade length 1/4 be oppositely contracted to blade tip width (Fig. 3) gradually again from outside 45 degree of root of blade.Concrete when implementing upper strata blade also can adopt the circular arc blade identical with lower floor blade or adopt existing common blade.
