For studying the whipping performance of the double horizontal axle agitator that returns to blade, the twin-shaft mixer that the nominal capacity of take is 100L is tested more.Wherein, have one group of stirring vane group (be stirring vane for singly putting formula) on single shaft on every shaft, the quantity of the stirring vane on every shaft is 9.Test concrete strength is C20, and mixing time is 45s.In the situation that raw material are identical with match ratio and stirring technique, by change, to return to blade quantity and carry out contrast test, result of the test is as shown in table 1.
Each test rating result of table 1
According to GB GB/T9142-2000, using the relative error Δ G of coarse aggregate quality in the relative error Δ M of slurry density in the mixing concrete thing of same tank different parts and unit volume mixing concrete thing as deliberated index, this index has embodied concrete macroscopical homogeneity, Δ M, Δ G are less, and concrete macroscopical homogeneity is better.The compression strength index (average strength and strength criterion are poor) of simultaneously also having measured the test block of 28d maturing, this index has embodied concrete microcosmic homogeneity, and average strength is larger, strength criterion is poor less, and concrete microcosmic homogeneity is better.
As can be seen from the test results, for there being the double horizontal axle agitator of 9 stirring vanes on single shaft, single while returning to lateral lobe sheet when what adopt traditional structure, owing to advancing, the quantity of primary blades is more, material is longer along the distance of mixing drum axial advance, material is longer in the time of axially-movable, thereby in identical mixing time, in mixing drum material to enclose stream systemic circulation times of exercise less, the homogeneity of concrete-agitating is poor, show as Δ M, Δ G and strength criterion poor all larger, average strength less (experiment sequence number 1), when reducing on this basis a propelling primary blades, increasing by one returns after lateral lobe sheet, material is suitably shortened in the distance of axial advance motion, therefore in identical mixing time, the enclose stream systemic circulation times of exercise of material in mixing drum suitably increases, and the overall blending homogeneity of concrete suitably improves (experiment sequence number 2), when reducing a propelling primary blades, increasing by one returns after primary blades again, while having 2 to return to lateral lobe sheet and 1 and return to primary blades in 9 stirring vanes, the distance of material axially-movable in mixing drum effectively reduces again, therefore in identical mixing time, continue to increase the axially-movable number of times of material, improved and enclosed stream systemic circulation times of exercise, make the obvious raising of having got back of concrete-agitating homogeneity, show as Δ M, Δ G and strength criterion poor all less, and average strength large (experiment sequence number 3), first three groups result of the test shows, the quantity that blade is returned in increase can improve concrete blending homogeneity, particularly increase and return after primary blades, owing to returning to primary blades, material is played to the elementary effect of returning, coordinate and to return to lateral lobe sheet and more strengthened and return to effect, concrete blending homogeneity is improved comprehensively, but return after primary blades when increasing again one, in 9 stirring vanes, there are 4 to return to blade, it is the poorest in four groups of tests (experiment sequence number 4) on the contrary that not only concrete blending homogeneity is not improved, this be because on single shaft, return blade quantity be greater than stirring vane total quantity on single shaft 1/3rd after, double horizontal axle agitator promotes the enclose stream motion of material in mixing drum and changes, material is now from mixing drum two ends along shaft to mixing drum center move toward one another, and in shaft center, become cone to pile up, by fan-shaped wandering from the vertex of a cone, no longer there is material enclosing in mixing drum and flowed systemic circulation campaign, be difficult to eliminate the original inhomogeneities of bringing while feeding intake, cause concrete-agitating homogeneity significantly to reduce.Evidence, the quantity of returning to blade on single shaft is not more than under 1/3rd the prerequisite of returning to blade and propulsion blades quantity sum, increases the blending homogeneity that the quantity of returning to blade can improve mix.
The above; it is only preferred embodiment of the present invention; not the present invention is imposed any restrictions, every any simple modification, change and equivalent structure transformation of above embodiment being done according to the technology of the present invention essence, all still belongs in the protection domain of technical solution of the present invention.
