Description
Technical Field
The invention particularly relates to an out-of-barrel stirring mixer and a cleaning device and a cleaning system thereof.
Background
Dry mixtures such as cement and the like are mostly stirred with a mixer to form cement cured substances for disposal by using medium and low radioactive waste liquid and waste resin generated in the nuclear power station and nuclear field. With the development of industrial scale treatment plants, the amount of waste liquid required to be treated is large, the radioactivity level is high, and the cement curing technology by stirring outside a barrel is suitable.
The working principle of the stirring mixer outside the barrel is that cement and feed liquid are fully and uniformly stirred in the stirring barrel, cement paste is discharged after the preset requirement is met, the cement paste is filled into a final curing barrel for curing and maintenance, and the mixer is cleaned and then reused. Its advantages are uniform stirring, high performance and treating power, high filling coefficient (up to 95%), and high adaptability to waste. The disadvantage is that regular flushing of the agitator mixer is required during operation.
The inner wall of the stirring barrel, the top cover, cement, feed liquid, the mouth of the feeding pipe, the stirring paddle and other parts of the stirring mixer have different degrees of contamination in the operation process. The normal operation of equipment can be influenced to the pollution accumulation, and the cement accumulation of grout feed opening department produces the influence to the sealed face of feed opening to lead to leaking. In a common cleaning mode, cement can be solidified and attached to the inner wall of the stirring mixer after being stained, and cannot be removed in a common spraying mode; in radioactive environments, direct cleaning by personnel is not allowed, so these cleaning means are not suitable; also, the waste water produced by the washing is radioactive, expensive to treat and increases the amount of radioactive waste.
