Mixer
Technical field
The utility model relates to a kind of mixer, is specifically related to a kind of mixer of the S of having shape blade construction.
Background technology
Mixer is widely used in fields such as metal metallurgy smelting, and fuel or mineral material etc. is mixed stirring, is divided into vertical mixer and horizontal mixer.At present, mostly the stirring vane of traditional mixer is planar structure, and the resistance that produces during stirring is big, stirs inhomogeneously, has reduced stirring efficiency.
Summary of the invention
The purpose of the utility model is the defective that exists in the prior art in order to solve, and a kind of mixer that resistance is little, efficient is high that stirs is provided.
In order to achieve the above object, the utility model provides a kind of mixer, comprises drive unit, frame, mixing drum, shaft and is located at the stirring vane on the shaft; Stirring vane comprises the rotating disk that is fixed on the said shaft, and at least two blades that on rotating disk, along the circumferential direction are provided with; Blade integral is S-shaped.
Further improvement to the utility model is: above-mentioned blade is located on the side end face of rotating disk.Shaft is two, parallel up and down being distributed in the mixing drum, and be respectively the meshing gear drive rotation in opposite directions of 1:1 by two gearratios; The alternate setting of stirring vane on two shafts.Wherein a shaft links to each other with drive unit.
The utility model is compared prior art and had the following advantages: stirring vane adopts S shape blade, has effectively reduced resistance, has improved stirring efficiency; Adopt cross-compound arrangement simultaneously, in whipping process, the stir speed (S.S.) that makes material obviously increases on year-on-year basis, stirs more evenly, has further improved stirring efficiency.

Among the figure, 1-frame, 2-mixing drum, 3-shaft, 4-stirring vane, 5-gear, 6-drive unit, 21-charging aperture, 22-discharging opening, 41-rotating disk, 42-blade, 421-outer rim.
The specific embodiment
Below in conjunction with accompanying drawing the utility model mixer is elaborated.
As shown in Figure 1, the utility model mixer comprises frame 1, is fixed on the mixing drum 2 on the frame 1, the drive unit 6 that links to each other with mixing drum 2, shaft 3, stirring vane 4 and gear 5.Mixing drum 2 tops are provided with charging aperture 21, and the bottom is provided with discharging opening 22.Shaft 3 is two, parallel up and down being symmetrically set in the mixing drum 2, and wherein a shaft links to each other with the output shaft of drive unit 6, and two gear 5 drives rotations in opposite directions that shaft 3 is 1:1 through intermeshing two gearratios respectively.Stirring vane 4 is fixed on the shaft 3, and distributes alternately on two shafts, guarantees that stirring vane 4 does not have interference each other when rotating.In conjunction with Fig. 2, stirring vane 4 comprises the rotating disk 41 that is fixed on the shaft 3 and is located at the blade 42 on the rotating disk that this blade 42 along the circumferential direction is fixed on the side end face of rotating disk 41.Blade 42 is crooked S-shaped, and blade 42 outer rims 421 be arc, can effectively reduce resistance and flow-disturbing, and improve rotary motive power and increase rotating speed, thus the raising stirring efficiency.
When mixing drum 2 rotated, two shafts 3 were driven in opposite directions by pitch wheel 5 and rotate, and rotate thereby drive stirring vane 4, and the S shape tangent plane of blade 42 can reduce resistance, is convenient to material and throws away blade with higher speed, improves the mixing effect of material.
