Description
Technical field
The present invention relates to a kind of broken shell agitating device, particularly a kind of easily broken shell agitating device of the liquid container of crust of liquid level that is applicable to.
Background technology
In reality productive life, the solid-state semisolid of breaking reservoir top crusts, freezes, and allows liquid level effectively be exposed in gas phase, or guarantees the apparatus of overflowing safely of liquid internal gas, in fields such as agriculture water, chemical industry, coating, printing and dyeing, has many application.Typical application surely belongs to anaerobic fermentation and produces biogas.In anaerobic fermentation tank, bottom is biogas residue and biogas liquid, and top is biogas, often has floating type natural pond slag crust phenomenon on liquid level.Crust can cause material stirring inhomogeneous, and the biogas of generation is overflowed and is obstructed, and causes whole natural pond processed inefficiency.Only have by good mixing of materials and stir and just can guarantee fully contacting of microorganism fungus kind and fresh material, guarantee that tank inner transmission matter diabatic process stablizes.Mechanical agitation is current the most frequently used anaerobic jar material stirring mode.
Chinese patent literature CN2905778 discloses a kind of " Multifunctional methane septic tank ", this invention is provided with broken shell and draws plate combination on power transmission shaft, power drives power transmission shaft rotation, thereby drives broken shell to draw plate rotation, so by broken shell paddle in one's power the crust in scope smash.Liquid level natural pond slag crust problem in theory can have well been tackled in this invention, having a problem only not yet solves: liquid level is just dynamic change, broken shell draws that plate hight is low to be fixed, the just right chance of both height is uncommon, too highly too lowly all can cause broken shell to draw the invalid idle running of plate, the solution thinking of this invention has also just been fallen through.
Summary of the invention
The technical issues that need to address of the present invention are: provide a kind of applicable liquid level domain of walker larger broken shell agitating device.
A kind of broken shell agitating device of the present invention, comprise motor, reductor, shaft and be arranged at least one group of stirrer paddle on shaft, described shaft topmost overlaps actively and has connecting ring, on connecting ring, be laid with some stirrer paddles, the blade of this group stirrer paddle is established Packed floating chamber; Described shaft shape of cross section is ellipse or polygon, and connecting ring centre bore mates adaptation with it, or described shaft is connected with bond structure with keyway with connecting ring.Because the working face of the blade of this type of mixer will change by synchronization lifting along with the eustasy of liquid level, so it is most suitable selecting the structure that floats on liquid level, the present invention has designed the floating chamber of sealing for this reason on blade, and it can provide buoyancy, can pour into again weight and regulate buoyancy, kill two birds with one stone; When guaranteeing that blade can drift along with liquid level, can also be along with shaft rotates, so ellipse, polygon that axle and connecting ring are designed to match each other (are preferably regular polygon, make selection and processing simply), or both are connected with the structure of keyway and key, be that axle and connecting ring are established keyway, with key, embed and fix.
When shaft cross section is ellipse, be that symmetrical fixing in original circular shaft (as welding, sunk screw spin) has arc paster.So can make full use of ready-made circular shaft.
When shaft cross section is polygon, described polygon is preferably regular polygon, makes selection and processing simple.
As preferably, described oval or polygonal height and liquid level domain of walker adapt.The unsteady scope of liquid level is not holoaxial height, thus the height that shaft section is processed also only need to be slightly larger than liquid level domain of walker need to, both guaranteed use, saved again processing.
An optional scheme, the cross section of described blade is the downward triangle of acute angle.This triangle top will float on liquid level, and its acute angle will be immersed under liquid level, and broken shell stirring action is better.
Another optional scheme, described connecting ring is provided with 2 above screws, is screwed with bottle in screw.With bottle, substitute blade, material is easy to get, easily assembles, easily changes, and also carries floating chamber, can fill with according to need mass to control the position of drifting along in bottle.As preferably, described screw is had to 2-3 row in vertical direction, the bottle in screw is close to, and forms bottle row, to adapt to different broken shell thickness.
The present invention adopts law of buoyancy well to solve the adjustment of hulling machine to liquid level, and holistic cost poor efficiency is high, simple in structure, and broken shell effect is fine, is worth promoting in each application.

The present invention has solved the adjustment of hulling machine to liquid level well.Overall structure is simple, and cost is low, and efficiency is high, is worth promoting in each application.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is described further.
Embodiment 1.See Fig. 1, broken shell agitating device of the present invention, is arranged on the anaerobism tank body 6 of high concentration material.Motor 1 and reductor 2 are positioned at anaerobism tank body 6 tops, and shaft 3 is from anaerobism tank body 6 tops deeply to bottom, and shaft 3 tail ends are connected with two groups of stirrer paddles 5.See Fig. 2, Fig. 3, the connecting ring 4 of a trough of belt is arranged at its top, with the shaft pivot bush unit with key 7/ keyway arrangements.Uniform 4 stirrer paddles on connecting ring.Packed floating chamber 5-1 is established on each stirrer paddle top.In floating chamber, can fill weight to regulate its sink-float degree.
During tank body fermentation, connecting ring 4/ stirrer paddle 5 can be servo-actuated with material liquid surface.During stirring, motor 1/ reductor 2/ shaft 3 starts to rotate, and whole agitating device is in the interior rotation of anaerobism tank body 6.One group of stirrer paddle being located at liquid bottom is responsible for the stirring of bottom liquid.No matter dextrorotation derotation of the one group stirrer paddle of crust on liquid level 5, all smashes the scum layer on liquid level by self structure, avoids scum silica frost to be further accumulated as shell, affects anaerobism tank body 6 inner transmission matters.
Embodiment 3.Be applicable to small-sized tank body.See Fig. 7, the cross section of this routine shaft 3 is processed into square in liquid level domain of walker section, and connecting ring 4 centre bores are also square, and both are socketed actively.This routine connecting ring 4 is provided with upper and lower two groups of screws, every group 4 and uniform.In 8 screws, in screw, be screwed with 8 plastics or glass bottle, upper and lower two bottles of coordination are close to into bottle row.In lower group of 4 bottles, pour water, to adjust buoyancy.With upper and lower bottle, form bottle row and serve as stirrer paddle, twice laid, cost-saving, be not afraid of pollution, installation transposing is convenient, achieves many things at one stroke.
More than describing and be the explanation of content of the present invention and explanation, is for helping to understand the present invention's technology contents, but not any limitation of the invention.Any employing is equal to alternative technological means enforcement the solution of the present invention and all belongs in the claims in the present invention protection domain.
