The best agitator is water and a bit of experience.I have often herd of lads saying that so and so's agitator "wouldn't stir yer tae" but you would have to take such a remark with a "pinch of salt".What tank was it it ,and who was operating it. In an ideal world this kind of hardchip shouldn't occur,but unfortunately it does,with lads taking out an odd load of water and so on. Then the problem starts because whats left is too thick to suck out a few loads to make room for a few loads of water.I find with tanks like that its best to keep the nozzle in close and stir just the first span,then a few loads can be removed and there is room for water. Generally, the food wastes or biomass slurry are non-Newtonian fluid, and hence viscosity depends on shear rate and temperature having an index of flow behavior is less than one. The new range of Conor megamix high performance slurry pumps have unrivalled mixing power and are ultra-efficient. Hence substantial scale-up factors are required to apply the results to full-size systems which may be 1000 m3 or more, and therefore slurry mixer design.
Firstly, using the concept of Reynolds number and later on the relation provided by Dave and John, is useful in designing the agitator tank. Similar design to what you posted about, we’ve got 4 8 inch baffles that run to the top of the cone on the agitator. High-efficiency impeller for high-flow rate and optimal mixing performance. I find if you try this approach with a tank that has a small bit of water in it ,you will be flying for about two minutes until the nozzle of the agitator lucks like an icing gun. The design of an agitator is carried with two types of concept. We use our props to harvest into, it doesn’t look like it would but the agitator does a great of keeping the slurry homogenized for pitches. Specially designed agitator range conceived for continuous, heavy duty operation (24/7/365) Up to 200 m3 volume mixing capacity with a single agitator per tank. Agitating tanks is never straight forward,experience of the tank and the type of slurry that's in it ,is important ,or your going to waste diesel.Ī tank that will have plenty of water in it,can usually be attacked by sending the flow away down the tank,as by the time that its starts to thicken up a bit the big lumps will all be broken either ways.
