What to do if it sinks to the bottom after stirring stops
Thread Content
During production, the reaction was halted due to a damaged water supply pump; when it was restarted later, the mixer would not rotate. Ours is a mixing tank with a diameter of 2.5 meters; the blades are located 0.8 meters above the bottom, and the tank contains 6.5 tons of material with a specific gravity of 3 tons per cubic meter. I would like to ask if anyone has encountered similar problems in actual production and how they handled them.
Manually rotate the motor fan, if it can be rotated. . . Thank goodness. . If it can’t rotate. . . . Dig by hand! ! ! ! ! /
In such cases, manual turning of the shaft is usually required first, but since your material has a high specific gravity and the blades are located quite high above the bottom, it presents significant difficulties. At the same time, you can try introducing high-pressure air through the bottom valve to stir things up, along with manual turning of the shaft; whether it will work depends on your luck! ! !
Impressive – you’ve managed to keep the equipment running, and you still refuse to give in to it? . . . Go in and clean it manually. . . :lol
Don’t start the mixer lightly, as it can burn out the motor.
As stated by the poster, the material has a density of 3 tons per cubic meter for a weight of 6.5 tons, and the mixing tank has a diameter of 2.5 meters with the blades located 0.8 meters above the bottom. So the volume below the blade is 3.9 cubic meters, while the volume of the material itself is 2.16 cubic meters; it’s quite unlikely that it can rotate then, right? Given this situation, there are only two possibilities: 1. You used too much material. 2. The mixing mechanism of the equipment is damaged, the edges are scraped, or the bearings are broken. Please fix it
The motor must absolutely not be turned on! The possibility of restarting it by manual cranking is very low. Manual cleaning is still the way to go.
We encountered this issue several times; on a few occasions we started the rotation process by diluting the material or using a discharge pump to remove as much of the material as possible and then diluting it with water to enable rotation. In the worst case, it was not possible to start the rotation at all, and the material could not be discharged either. It took almost a day and night to manually remove the material before things could get back on track. The density of our material is not very high, around 1.12, but its viscosity is quite high, approximately 4000 cp. With such a high density, it will be very difficult to operate even if the viscosity isn’t high (given the conditions you’ve provided, it probably isn’t high, and the mixing space is fairly large). Try exporting part of the material to expose the stirrer before proceeding with the processing
The material has a high density, so it’s less likely to be blown away by high-pressure air; manual cleaning is the better option
Turn the drum manually; do not start the mixer. Then stir it with a pickaxe, add the solvent, and after diluting it to the appropriate degree, start stirring again. If that doesn’t work, manual digging will be the only option.
To do it quickly and cheaply, just hire people to dig； If you want to demonstrate advanced features, use pipes to feed oil-free compressed air or nitrogen, and add water to slowly cause the sediment to rise to the surface
