Abstract
The invention relates to a multilayer stirring paddle structure capable of improving mixing effect and reducing sediment. The multilayer stirring paddle structure includes a blade divided into a bottom blade and a top blade, wherein the bottom blade is in a pushing type and pushes slurry to move downward during rotating; while the top blade is in a pulling up type, and pushes the slurry to move upward during rotating. According to the multilayer stirring paddle structure, mixing uniformity can be improved, bottom sediment can be reduced, and energy consumption can also be reduced.
Description
Technical field
The present invention relates to a kind of mixed effect that can improve and reduce the multiple impellers structure that precipitates, be applicable to the agitating device of alumina industry and all kinds of hinged joint oar of other hydrometallurgy industries tank diameter, can effectively improve mixture homogeneity and strengthen the flow rate of liquid of bottom land edge, the precipitation buildup that improve mixture effect, reduces energy consumption and reduce trench bottom.
Background technology
Present stage, in alumina industry and other hydrometallurgy production processes, the tank diameter that mixes use for solid-liquid often adopts hinged joint oar formula agitating device.
Traditional multilayer oar configuration mode is all press-down type, and namely when paddle turned round, each layer oar band hydrodynamic stream was done gyration, and liquid stream is stirred oar and pushes the below to simultaneously.The characteristic of press-down type paddle is: in cell body bottom, it is larger that slip impacts the flow velocity of corner etc. locating, and therefore, precipitation is more favourable for eliminating; But for cell body top, it is initiatively that slip moves downward, and ascending motion is passive, and therefore, this mode is disadvantageous for the suspension of solid particle in slip, and cell body top slip easily forms layering, and mixed effect is descended.In order to obtain enough uniformitys, must improve rotating speed, consume larger power.
Relative with the press-down type paddle, also have a kind of paddle configuration mode of pull-up, namely when paddle turned round, each layer oar band hydrodynamic stream was done gyration, and liquid stream is stirred oar and pulls to the top simultaneously.The characteristic of pull-up paddle is: in cell body bottom, it is all less that slip impacts flow velocity and the sphere of action corner etc. located, therefore, and than being easier to form precipitation; But for cell body top, it is that initiatively descending motion is passive that slip moves upward, therefore, this mode is highly beneficial for the suspension of solid particle in slip, and it is very high that cell body can reach mixed uniformly effective depth, can significantly improve mixture homogeneity.
Summary of the invention
The present invention provides a kind of mixed effect that can improve to reduce the multiple impellers structure that precipitates for solving the problems of the technologies described above, purpose is feed liquid in tank diameter to be flowed rationally control, flow velocity and the intensity of strengthening groove bottom feed liquid, improve simultaneously the rate of climb of cell body middle and upper part slip, improve effective mixture homogeneity scope.
To achieve these goals, the present invention is achieved in that a kind of mixed effect that can improve reduces the multiple impellers structure that precipitates, and comprises blade, and blade is divided into bottom paddle and top layer oar, and bottom paddle is press-down type, promotes slip during the bottom paddle rotation and moves downward; The top layer oar is pull-up, promotes slip during the rotation of top layer oar and moves upward.
The number of plies of described bottom paddle and top layer oar is respectively at least 1 layer.
Bottom paddle and top layer oar are hinged joint oar, push-paddle or other oar type with axial flow.
Advantage of the present invention and effect are as follows:
The present invention combines the advantage of two kinds of paddle configurations.Bottom paddle is press-down type, impacts at cell body bottom slip the flow velocity of corner etc. locating larger, and precipitation is highly beneficial for eliminating; The top layer oar adopts pull-up, and highly beneficial for the suspension of solid particle in slip, it is very high that cell body can reach mixed uniformly effective depth.Adopt the pull-up upper-layer paddle, just can reach the mixing effect of multilayer press-down type paddle with the less number of plies.Therefore, this multilayer oar collocation form not only can improve mixture homogeneity and reduce the bottom land precipitation, can also reduce energy consumption.

The specific embodiment
The below is described in detail by reference to the accompanying drawings to inventive embodiment, but the protection domain of invention is not limit by embodiment.
As shown in Figure 2, a kind of mixed effect that can improve reduces the multiple impellers structure that precipitates, and comprises blade, and blade is divided into bottom paddle 3 and top layer oar 2, and bottom paddle 3 is press-down type, promotes slip during bottom paddle 3 rotation and moves downward; Top layer oar 2 is pull-up, promotes slip during 2 rotation of top layer oar and moves upward.
The number of plies of described bottom paddle 3 and top layer oar 2 is respectively at least 1 layer.Bottom paddle and top layer oar are hinged joint oar, push-paddle or other oar type with axial flow.
Operation principle of the present invention:
Bottom paddle adopts press-down type, i.e. promote slip during paddle rotation and move downward.It is larger that the press-down type bottom paddle impacts at tank diameter 1 bottom slip the flow velocity of corner etc. locating, and precipitation is highly beneficial for eliminating; The top layer oar adopts pull-up, i.e. promote slip during paddle rotation and move upward.The top layer oar adopts pull-up, and highly beneficial for the suspension of solid particle in slip, it is very high that cell body can reach mixed uniformly effective depth.Adopt the pull-up upper-layer paddle, just can reach the mixing effect of multilayer press-down type paddle with the less number of plies.Therefore, this multilayer oar collocation form not only can improve mixture homogeneity and reduce the bottom land precipitation, can also reduce energy consumption.Therefore this multilayer oar collocation form, have good mix uniformly effect and the effect of removing the bottom land buildup, can significantly reduce power of agitator simultaneously.
