Description
Technical field
The present invention relates to a kind of slurry transmission pump, relate in particular to a kind of band for lightweight aggregate concrete and stir air pressure transmission pump and carrying method.
Background technology
Lightweight aggregate concrete is to be formed through being uniformly mixed by cement, fly ash, sand, particle foam, water and various additive.Cement, fly ash, sand, water proportion are larger, once the material mixing under static state, cement, fly ash, sand, water are generally all first to sinking, and particle foam material proportion is lighter, generally all to floating.The existing air pressure transmission pump for lightweight aggregate concrete is all generally to adopt pressurized air by particle foam, mortar mixture press-in die.But adopt merely pressurized air binder to enter mould and have a very large defect, that is exactly foam beads, mortar mixture stirs evenly again in puddle mixer, but mixture material enters after air pressure transmission pump, because the proportion of foam beads, mortar, water is different, add the vibration in the transport of air pressure transmission pump, the mixture being stirred is in the time being pressed into combined wall board mould, cement mortar is introduced into mould often, foam beads and floating superincumbent many, after mortar die casting is complete, remaining a lot of foam beads are pressed and are not entered mould.It is also inconsistent that die casting above enters cement, mortar and foam proportioning in the mixture that the mixture of mould and die casting below enters mould, batching while causing stirring changes a lot with the batching that enters mould, also cause plate inner structure and the weight per unit area of composite lightweight wall plate also to change, also relative increasing of weight error between plate and plate simultaneously.
Because mortar when the die casting leaves in air pressure transmission pump motionless, when after injecting compressed air, heavier mortar is tried to be the first from discharging below, upper foam is more, and mortar becomes dry, flowing power variation, causes same stock to enter the front and back phase of mould in die casting, gaseous tension also differs and is stuck in to, material the phenomenon that in conveying pipeline, pressure is not gone out and also happens occasionally.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of band for lightweight aggregate concrete that the lightweight aggregate concrete being stirred is continued in the process of press-in die stir and stirs air pressure transmission pump and carrying method.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
After claim examination & verification, we supplements herein
Compared with prior art, the main advantage of technical scheme of the present invention is as follows:
1. the foam, the mortar ingredient that puddle mixer are mixed are made ceaselessly low rate mixing, and the batching that makes die casting enter the mould front and back phase is consistent, thereby have ensured well the inherent quality of composite lightweight wall plate;
2. after the mixture in the complete pressure container of die casting, due to the helicallobe scraping that gyrates in pressure container, not sizing of pressure container inwall, does not deposit residue material, and in pressure container, discharge is clean;
3. be provided with two seal closures at pressure container two, seal closure is connected with tracheae with pressure container, seal closure internal gas pressure is consistent with in pressure container, wallboard compound slurries in tank like this, the gap of the main shaft that just can not rotate in tank, in seal closure, be pressed into, meanwhile, both ensured that S. A. can rotate, and kept again the pressure in pressure container constant;
4. the moving velocity of year pump truck can be handled by operator, coordinates PLC circuit motor is accelerated and slow down by frequency converter, accelerates, slows down excessively steadily, and circuit is reliable and stable;
5. automatically controlled part all adopts frequency converter and the control of PLC circuit, and circuit is simple, stable performance, and good reliability, failure rate is low, controls flexibly.
