Abstract
The invention discloses a three-shaft stirring decomposing tank including a tank body (1), a tank cover (3), a motor (4), a material lifting pipe (5), a foot margin member (7), a cleaning door (8), a base bearing (9) and a bottom plate(10), within three stirring devices (6) are arranged in the tank body (1), the lower end and the upper end of each stirring device (6) are respectively matched with the base bearing (9) and the motor (4). The stirring power, impeller diameter and weight of the stirring devices are reduced correspondingly reduced, the manufacture and installation are easy, the repair and maintenance are convenient, the operation is stable and efficient, and the three-shaft stirring decomposing tank can meet the technical requirements of large scale alumina production.
Description
Technical field
The present invention is the device decomposing for flowsheet of slurry agitation in alumina producing, belongs to alumina producing apparatus field.
Background technology
In alumina producing, the purposes of decomposer is that the ore pulp after stripping is carried out to decomposition.The stirring of decomposer should meet the sufficient mix suspending of slip can not destroy again growing up of crystal seed.The decomposer maximum specification being widely used in alumina production line in present stage is Φ 14 × 37m, along with the development of alumina production line maximization, the decomposer of Φ 14m specification can not meet need of production, need to develop diameter is the decomposer that Φ 16m ~ 20m is even larger, decomposer stirring pattern present stage is single shaft MIG pattern, and maximum diameter of propeller blade is 10m.As increase decomposer diameter, diameter of propeller blade is along with increase, present stage, large diameter blade was manufactured and processing and install and all more difficultly meet realistic accuracy requirement, transport, maintain and replace difficulty, because single shaft diameter of propeller blade is excessive, the very easy buildup of axle central zone and bottom land periphery, stops groove cleaning turnaround shortening in making to produce.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of three axles to stir decomposer, the power of agitator of whipping appts, diameter of propeller blade, weight is corresponding reduces, and manufactures and install easily, maintenance, easy to maintenance, operate steadily efficient, meet the processing requirement that alumina producing maximizes.
The technical solution used in the present invention: a kind of three axles stir decomposer, comprise cell body, have three cover whipping apptss in cell body, and mate with base bearing and motor respectively whipping appts lower end and upper end.Three cover whipping apptss are evenly distributed on same circumference.Whipping appts has at least one metaplasm leaf, and diameter of propeller blade is less than or equal to 1/3rd of cell body diameter, and bottom blade is 0.5m from base plate distance, and the spacing between adjacent blades is less than or equal to 80% of diameter of propeller blade.There is baffle plate cell body inner side.
Cell body, groove lid, motor, extraction pipe, leg members, clean-out door, base bearing and base plate form the agent structure of three axle steel basins.Cell body is used for filling decomposition slurries.Groove lid is for supporting the relevant auxiliary facility on whipping appts and decomposer.Clean-out door is for periodic cleaning decomposer.Extraction pipe is for decomposer discharging.Leg members and base plate are used for supporting whole decomposer.It is wherein a set of and other two overlap rotating Vortex or counter rotatings when three cover whipping apptss use, in use can adjust according to actual needs turning direction, turn to and mixing speed can effectively reduce the interference effect between every diaxon and promote mutually mixing effect by adjustment.
The present invention adopts after three cover whipping apptss, and diameter of propeller blade obviously reduces, and the precision of processing each side for the manufacture of blade is all easy to ensure, transports also convenient a lot.The simultaneously corresponding minimizing in stagnant area that reduces also can cause axle centre of diameter of propeller blade, can solve the problem of the easy buildup in single shaft center well.By calculating, when three axle diameter of propeller blade are about two of single shaft diameter of propeller blade/for the moment, because power becomes five power proportional relations with diameter, the power ratio single shaft of comprehensive relatively rear three axle unit volume consumption reduces 20 approximately percent, and low power maintenance of motor is easier.Three axle blades cover region increase compared with single shaft, cell body neighboring area can be stirred more fully, mixes more even, periphery scab and buildup region will reduce, can extend and stop groove cleaning cycle, raising productive efficiency.
Brief description of the drawings
Fig. 1 is that three axles stir decomposer structural representation;
Fig. 2 is that three axles stir decomposer sectional top view.
Embodiment
As shown in Figure 1, a kind of three axles stir decomposer, mainly comprise cell body 1, baffle plate 2, groove lid 3, motor 4, extraction pipe 5, whipping appts 6, leg members 7, clean-out door 8, base bearing 9, base plate 10.Cell body 1 is for filling decomposition slurries; Groove lid 3 is for supporting attached relevant device on whipping appts 6 and decomposer; Motor 4 is connected with whipping appts 6 upper and lower ends respectively with base bearing 9, motor 4 adopts flange to be connected with the stir shaft of whipping appts 6, whipping appts 6 has many metaplasms leaf, diameter of propeller blade is 1/3rd of decomposer tank 1 diameter, bottom blade is 0.5m from the distance of bottom land base plate 10, and the spacing between adjacent blades is diameter of propeller blade 80%; Cell body 1 inner side is provided with three baffle plates 2; Clean-out door 8 is for periodic cleaning decomposer; Extraction pipe 5 is for decomposer discharging; Leg members 7 and base plate 10 are for the whole decomposer of bottom support.
As shown in Figure 2, three cover whipping apptss 6 are evenly distributed on same circumference, when actual use wherein two cover whipping apptss 6 by clockwise rotating, a set of rotating counterclockwise in addition, or three overlap all rotating in same directions.In use procedure, can adjust according to actual needs turning direction.Turn to and mixing speed can reduce the interference effects of any two covers between whipping apptss 6 effectively by adjustment, promote mixing effect.
