The horizontal powder material mixer of the utility model can shorten the mixing time of powder materials, and enhance the mixing uniformity of the powder materials.
Description
The utility model relates to mixing apparatus, particularly a kind of mixer that is suitable for multiple powder mixing.
Industries such as chemical industry, agricultural chemicals, feed, food, medicine, dyestuff usually need powder and powder are carried out hybrid process.Hybrid process between this solid powder requires mixed powder that certain uniformity is arranged.And the uniformity of mixed powder depends primarily on the structure of agitating device in the mixer except time factor.At present, the horizontal double helical ribbon mixer that domestic and international feedstuff industry generally adopts, the main feature of its agitating device is to be fixed with two in the rotating shaft appearance to vary in size, two ribbon (see figure 1)s that the hand of spiral is opposite, horizontal double helical ribbon mixer is generally the single shaft single chamber, and the rotating speed of rotating shaft is slow (36-50 rev/min), and hybrid mode mainly is the convection current and the shearing of powder, the speed of powder upset turnover is slow, does not produce the rapid diffusion under the state of weightlessness.The time of its best admixture needs 3-5 minute, and its coefficient of variation CV that weighs the uniformity is about 5% (the mixture homogeneity coefficient of variation computational methods according to GB5918-86 obtain).Therefore longer with the required time of horizontal double helical ribbon mixer mixed powder, the coefficient of variation of mixing the back powder is big, the uniformity is relatively poor.
The purpose of this utility model is that a kind of improved horizontal powder mixer will be provided, and can shorten the incorporation time of powder and improve the uniformity that powder mixes.
Task of the present utility model is finished as follows: a kind of horizontal powder mixer, has fixed barrel, the discharging opening of charging aperture on the described barrel and strap brake plate, along the axial arranged rotating shaft in described barrel center, described rotating shaft is stretched out the outer end of barrel and is connected with power source by transmission mechanism, its characteristics are radially to be fixed with paddle in the interior rotating shaft of described barrel, paddle is made up of loom and two blades that are fixed on the described loom, two blades that are positioned on the paddle of described barrel rotating shaft two ends are arranged in parallel up and down, blade phase countershaft makes the angle and arranges, two blades that are positioned on the paddle of described rotating shaft middle part become the angle to arrange up and down, and described two blade phase countershafts make the angle and arrange.
The paddle at the utility model mixer rotating shaft middle part can be along rotating shaft to even layout.
The space angle of cut when blade phase countershaft on the paddle of the utility model mixer rotating shaft two ends makes the angle layout can be 15 °-30 °.
Space angle of cut when the following blade phase countershaft of the utility model mixer rotating shaft middle part paddle makes the angle layout can be 30 °-60 °, and the space angle of cut when the last blade of described paddle descends blade to make the angle layout relatively can be 30 °-90 °.
The horizontal powder mixer of the utility model is owing to adopt into two blade paddles that the angle is arranged, therefore the paddle that is rotated in barrel of powder overturns fast and is in the moment state of weightlessness in (120 rev/mins) process, most of powders all are arranged in the moving space of changeing of two blades, therefore to powder convection current, shearing, diffusion is all carried out at a high speed at short notice, thereby makes powder reach even mixing rapidly.
Make tracer with the CuO powder (particle is less than 300 orders) that oven dry is pulverized, with particle less than 200 purpose CaCO
3Powder is made diluent, both weight ratios are 1:1000, with mixer of the present utility model above-mentioned two kinds of powders are done the mixed-precision test, in the barrel of mixer, select eight positions to make sample point equably, its incorporation time, the CuO content of each sample point, the value of the coefficient of variation CV that obtains according to the GB5918086 computational methods sees the following form:
Incorporation time (second) | CuO content (‰) | Coefficient of variation CV (%) | |||||||
A | B | C | D | E | F | G | H | ||
15 30 60 120 | 1.12 1.13 1.12 1.13 | 1.11 1.11 1.15 1.12 | 1.08 1.10 1.17 1.14 | 1.15 1.14 1.13 1.19 | 1.18 1.19 1.16 1.15 | 1.23 1.16 1.10 1.17 | 1.21 1.17 1.17 1.16 | 1.16 1.14 1.15 1.16 | 4.40 2.63 2.18 1.95 |
As seen from the above table, after mixer turned round 1-2 minute, the mixture homogeneity of powder---coefficient of variation CV can reach about 2%, the powder mixed-precision 5% of the horizontal double helical ribbon mixer of ratio of precision that shows its mixed powder of mixer of the present utility model is much higher, and incorporation time also shortened to 1-2 minute from 3-5 minute and has good economic benefits and social benefit.
