Description
Technical Field
The invention relates to a clean slurry spraying device, in particular to a full-automatic clean slurry spraying device.
Background
The Prestressed Concrete Cylinder Pipe (PCCP) is widely applied to major water diversion and water transfer hydraulic construction projects such as south-to-north water diversion in China and urban water supply pipe network construction projects due to the excellent characteristics of large caliber, high pressure, deep earthing and long distance, and the durability of prestressed high-strength steel wires wound on the core of the PCCP directly influences the structural safety of the PCCP. The GB/T19685 'prestressed concrete cylinder pipe' national standard requires that cement paste with specified water-cement ratio is sprayed when wire winding is carried out, and the surface of the steel wire is effectively protected for the first time. The cement paste water-to-gel ratio on the surface of the steel wire is 0.625, the cement paste water-to-gel ratio has strong viscosity, the solidification speed is high, the stirred slurry is initially solidified for more than 45 minutes, sludge can be generated, and the cement paste can be solidified on the inner wall of a stirring barrel or a slurry pipeline if the cleaning is not timely and thorough.
In the prior art, the field slurry preparation is mainly manually operated, time and labor are wasted, the water-cement ratio is mainly controlled by the experience of operators, and in addition, the low water-cement ratio is favorable for the smooth work of a slurry spraying system, so that the water-cement ratio is lower than the technical requirement in the actual work. If the primary slurry preparation amount is too large, the slurry spraying before the initial setting of the cement slurry cannot be ensured, and the slurry spraying quality is seriously influenced.
When cleaning is generally carried out, workers directly take the water pipe to clean the stirring barrel, firstly, labor is wasted, secondly, if the responsibility of the workers is not strong, cleaning is not in place and not thorough, cleaning waste water is cleaned along one path of a slurry path pipeline and is directly sprayed out from a spray head, the operation of the workers is also influenced, the spray head is generally over against an operating concrete pipe, and residual slurry and waste water during cleaning can influence the spraying quality of the pipe if being sprayed onto the concrete pipe; the traditional straight pipe or flat pipe spray head is uneven in spraying, poor in atomization, serious in wear of the spray head and required to be frequently replaced.
The screw pump for conveying the slurry is generally of a horizontal structure, a gap is reserved between the lower part of the conveying rod and the cylinder wall, the slurry is easy to deposit on the cylinder wall due to large specific gravity, the traditional screw pump is not easy to clean, a layer of thick slurry is solidified below the cylinder wall after a long time, the conveying of the slurry is influenced, and the slurry is easy to generate sludge to block a slurry path.
In the prior art, the spraying speed is fixed, and when the rotating speed and the diameter of a concrete pipeline are changed, the spraying amount required by a unit area can be changed along with the change, and the requirement on the spraying quality cannot be met if the same set of spraying equipment is used.
In addition, in the prior art, the slurry and the air are mixed too early, the flow rate of the slurry-air mixture in the slurry spraying pipe is very high, the pipeline and the spray head are seriously abraded, and particularly the spray head needs to be frequently replaced, so that the cost of an enterprise is increased.
