Abstract
The utility model discloses a gas-liquid dispersing stirrer. The gas-liquid dispersing stirrer comprises a shaft sleeve and a circular disc which is arranged at the periphery of the shaft sleeve, wherein a plurality of paddles are arranged at the periphery of the circular disc; each paddle comprises two paddle split bodies, wherein one ends of the paddle split bodies are fixedly connected with each other, and the other parts of the paddle split bodies are far from each other to form a dispersing slot, the opening direction of the dispersing slot is consistent with the rotation direction of a stirring shaft; the hole diameter of the dispersing slot is gradually increased from the inside to the outside; and the outer diameters of one sides (deviating from the dispersing slot) of the paddles are gradually reduced from the ends at which the paddle split bodies are separated to the ends at which the paddle split bodies are connected with each other. The gas-liquid dispersing stirrer provided by the utility model can effectively reduce the generating cavitation on the back surfaces of the paddles, improves the gad-liquid dispersing capacity of the stirrer, and improves the dissolved oxygen rate.
Description
Technical field
The utility model relates to the agitator technical field, is specifically related to a kind of gas liquid dispersion stirrer.
Background technology
In the existing stirring system that ventilates, often there is one or more layers gas liquid dispersion stirrer to be used for carrying out Gas-Liquid Dispersion.In liquid, owing to the stirring of agitator, during the turning circle of compressed air process agitator, produce air pocket during the operation of blade back, so that compressed air is inhaled into air pocket, when air pocket along with centrifugal action during explosion, air pocket is divided into many tiny bubbles, so that the surface area that bubble contacts with liquid increases, thereby raising dissolved oxygen rate, but after air pocket was excessive, with so that the minute bubbles after final the dispersion are also bigger than normal, the Gas-Liquid Dispersion ability of agitator also reduced.
In addition, in the higher medium of some material viscosity, the Gas-Liquid Dispersion ability of agitator also can obviously reduce.
Summary of the invention
The purpose of this utility model is: for the deficiencies in the prior art, the utility model provides the gas liquid dispersion stirrer that a kind of Gas-Liquid Dispersion ability is high, mixing effect is good, thereby effectively reduce blade back from a side large air pocket of meeting liquid level, improve the dissolved oxygen rate in the liquid medium.
To achieve these goals, the utility model has adopted following technical scheme:
A kind of gas liquid dispersion stirrer, comprise axle sleeve and the disk that is arranged on the axle sleeve periphery, described disk periphery is provided with some blades, described blade comprises two blade splits, one end of described blade split is mutually permanently connected, the other end of blade split mutually away from, form the opening direction dispersion slot consistent with the shaft rotation direction, described dispersion slot from the inside to the outside bore increases gradually, described blade back from a side of dispersion slot by the blade split away from an end to the interconnective end external diameter of blade split dwindle gradually.
As preferably, described blade split is provided with some discharge orifices.After adopting above-mentioned preferred version, arranging of discharge orifice can effectively be reduced the projected area that the blade dispersion slot is met liquid level thoroughly, reduce power, medium fluid can flow to the dispersion slot back from saturating discharge orifice simultaneously, can reduce the size of back air pocket, effectively reduce the generation of blade back side air pocket, improve the Gas-Liquid Dispersion ability of agitator.
As preferably, described discharge orifice form strip or circular hole.After adopting above-mentioned preferred version, the saturating stream effect of the saturating discharge orifice of strip or circular hole is better, can medium fluid be passed through.
As preferably, described blade adjustable ground is arranged on the disk.After adopting above-mentioned preferred version, can adjust the slurry footpath of blade according to place environment in the medium fluid of reality, thereby improve Gas-Liquid Dispersion ability and the dissolved oxygen rate of mixing effect, agitator, adapt to various environment.
As preferably, the blade split fixed connection place of the lateral wall of the dispersion slot of described blade is provided with the blade fixed head, described disk week is along the adjustment hole that is provided with some rows, described adjustment hole is set in a row to the disk outside by disc centre, and described blade fixed head is provided with the connecting bolt that cooperates installation with adjustment hole.After adopting above-mentioned preferred version, can regulate more easily the slurry footpath of blade.
Gas liquid dispersion stirrer of the present utility model can effectively reduce the generation of blade back side air pocket, improves the Gas-Liquid Dispersion ability of agitator, improves dissolved oxygen rate.

The specific embodiment
Shown in Fig. 1-7, embodiment of the present utility model is a kind of gas liquid dispersion stirrer specifically, comprises axle sleeve 1 and the disk 2 that is arranged on axle sleeve 1 periphery, and the periphery of disk 2 is provided with 6 along the equally distributed blade 3 of disk 2 peripheries.Blade 3 comprises two blade splits 31, one end of two blade splits 31 is mutually permanently connected, the other end of blade split 31 mutually away from, form the opening direction dispersion slot 32 consistent with the shaft rotation direction, dispersion slot 32 from the inside to the outside bore increases gradually, the side that blade 3 deviates from dispersion slot 32 by blade split 31 away from an end to blade split 31 interconnective end external diameters dwindle gradually.
During work, agitator is along with shaft rotates, near the agitator medium fluid part medium fluid flows to notch one side that liquid level is dispersion slot 32 of meeting of dispersion slot 32, the fluid that enters dispersion slot 32 flows to dispersion slot 32 back sides from saturating discharge orifice 311, break the air pocket region of no pressure at dispersion slot 32 backs, thereby play the effect of breaing up bubble.Another part fluid enters the air pocket vacuum area at dispersion slot 32 backs along the back of dispersion slot 32.
