Abstract
The present invention relates to a kind of paddle, be applicable to being uniformly mixed of all kinds of tank diameter of aluminum oxide industry, be particularly useful for a kind of high performance tape guiding gutter arc surface paddle that tank diameter is higher to uniformity requirements, comprise stirrer paddle, it is characterized in that described stirrer paddle section is circular arc or approximate circle arc; The tangential direction that stirrer paddle meets stream limit is parallel with stirrer paddle gyratory directions; Below stirrer paddle, offer diversion groove near the position of root and end, direction is identical with blade rotary direction.Advantageous effect of the present invention is as follows: stir energy consumption low, mixing effect is good, improves blade whipping performance; Significantly improve the buildup problem of bottom land.More than 40% is reduced with same specification hinged joint oar phase specific energy consumption.
Description
Technical field
The present invention relates to a kind of paddle, be applicable to being uniformly mixed of all kinds of tank diameter of aluminum oxide industry, be particularly useful for a kind of high performance tape guiding gutter arc surface paddle that tank diameter is higher to uniformity requirements.There is high mixture homogeneity, low energy consumption and good suppression precipitation feature.
Background technology
Present stage, in aluminium oxide hydrometallurgy production process, all kinds of tank diameter adopts paddle agitating device usually, and paddle form is hinged joint oar.The blade of hinged joint oar is dull and stereotyped, and have angle with the surface of revolution, about 30 ° ~ about 45 °, incline direction is contrary with liquid stream direction of rotation.During work, central shaft drives paddle to do circumference rotation, and liquid moves downward along blade lean direction.Liquid stream turns round and descending motion under the drive of paddle, completes the mix and blend of liquid.There is following problem in hinged joint oar, (1) due to hinged joint paddle blade be a clinoplain, liquid stream is transferred suddenly when running into blade, produces larger resistance; (2) fluid is running into after stirrer paddle flow direction transfers, and be not all discharge from stirrer paddle bottom, but major part is discharged from stirrer paddle bottom, also has small part to discharge from stirrer paddle top, whipping performance is reduced.Therefore, the mixing effect of hinged joint oar is poor, and energy consumption index is higher.
Summary of the invention
The present invention, for solving the problems of the technologies described above, provides a kind of high performance tape guiding gutter arc surface paddle, and object improves the flow velocity of bottom land center and edge slip, suppresses precipitation, improves mixture homogeneity.
In order to solve the problems of the technologies described above, the present invention is achieved in that a kind of high performance tape guiding gutter arc surface paddle, comprises stirrer paddle, and described stirrer paddle section is circular arc or approximate circle arc; The tangential direction that stirrer paddle meets stream limit is parallel with stirrer paddle gyratory directions; Below stirrer paddle, offer diversion groove near the position of root and end, direction is identical with blade rotary direction.
The deflection shaft center, diversion groove direction of described stirrer paddle root; The deflection bottom land corner, diversion groove direction of stirrer paddle end.
Described stirrer paddle width narrows outward gradually from root, outer chamfer.
The limit that goes out to flow of described stirrer paddle bends gradually, parallel with liquid flow movement direction.
The quantity of described stirrer paddle is 2 ~ 6.
Advantageous effect of the present invention is as follows: 1. stir energy consumption low, the shape of blade surface is arc surface or approximate circle arc shape, and liquid stream changes flow direction gradually when running into blade, and the resistance of generation is less, and energy consumption is reduced.2. mixing effect is good, and the tangential direction of blade top edge is parallel with stirrer paddle direction of rotation, effectively reduces the liquid stream flowed out from blade top edge, improves blade whipping performance; 3. the limit that goes out to flow of stirrer paddle bends gradually, parallel with liquid flow movement direction, can reduce the resistance to liquid stream, reduce power consumption further.4. below blade, be provided with multiple diversion groove near the position of root and end, improve the flow velocity of bottom land center and edge slip, significantly improve the buildup problem of bottom land.More than 40% is reduced with same specification hinged joint oar phase specific energy consumption.

In figure 1, cell body; 2, baffle plate; 3, shaft; 4, propeller boss; 5, stirrer paddle; 6, diversion groove; 7, end; 8, root; 9, go out to flow limit.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail.
A kind of high performance tape guiding gutter of the present invention arc surface paddle as shown in the figure, comprise stirrer paddle 5, stirrer paddle 5 section is circular arc or approximate circle arc; The tangential direction that stirrer paddle 5 meets stream limit is parallel with stirrer paddle gyratory directions; Below stirrer paddle 5, offer diversion groove near the position of root 8 and end 7, direction is identical with blade rotary direction; The deflection shaft center, diversion groove 6 direction of stirrer paddle 5 root 8; The deflection bottom land corner, diversion groove 6 direction of stirrer paddle 5 end 7; Stirrer paddle 5 width narrows outward gradually from root 8, outer chamfer, and the limit 9 that goes out to flow of stirrer paddle 6 bends gradually, parallel with liquid flow movement direction, and the quantity of stirrer paddle 5 is 2 ~ 6.
Wheel hub 4 is for being fixed on shaft 3 by stirrer paddle 5; Shaft 3 is located in cell body 1, and vertical baffle 2 is located on the inwall of cell body 1.
