Background technology
Current concrete mixer is used for the realm of building construction, is mainly used in concrete stirring and storage.In the process of concrete mixer work, need adding large water gaging in mixer, so that same cement mixing.
In current mixer, the discharging device that producer generally designs is water outlet, connects water pump or water tank, imported in mixer by water by water pipe.Current institute problems faced is that the adopted excessive water discharging time of water pipe caliber is long, hydraulic pressure is too small, and easy condensate water cement mortar on mixing arm and scraper, causes concrete to stir uneven, affect concrete quality, also bring sizable labour intensity to mixer cleaning attendant simultaneously.
Current domestic mixing plant adopts microcomputer automatic control mode mostly simultaneously, be limited by human factor less, be limited by plant equipment factor larger, owing to often occurring with uncertain factor in whipping process, therefore often there is the phenomenon such as aggregate spill-over, mixer blocking, both caused labour and material to waste in a large number, and be difficult to again keep continuing uninterrupted production, cause mixing plant production efficiency to be in low-level state for a long time like this.
Therefore need the problem according to running in actual production process or finding, mixing plant machinery discharging device part is improved, enhances productivity.
Summary of the invention
Technical problem to be solved by this invention is the deficiency for above-mentioned existence, there is provided a kind of structure simple, with low cost, the basis not changing existing mixer structure realizes reduce water discharging time, increase hydraulic pressure, reduce concrete coagulation, improve concrete-agitating level, reduce small-size concrete mixing plant and the concrete-agitating method of unexpected factor risk and waste.
The technical solution adopted for the present invention to solve the technical problems is:
Small-size concrete mixing plant, include the storage warehouse in feeding system, the dividing strip of storage warehouse bottom and flat belt, also include mixing drum, motor and reductor are housed above mixing drum, reductor connects revolving body and extend in mixing drum, multiple mixing arm is installed bottom revolving body, mixing arm is provided with blade, it is characterized in that: described mixing drum is provided with discharging device, described discharging device includes apopore and the thick water pipe be communicated with it and thin conduit, thick water pipe and thin conduit are arranged on the both sides of mixing drum respectively, and jointly connect centrifugal water pump, the caliber of wherein said thin conduit is 1/2nd of thick water pipe.
In such scheme, the mouth of pipe of described thin conduit is just to mixing arm direction.
In such scheme, described apopore is divided into thick water pipe apopore and thin conduit apopore, and both are the apopore group that multiple little apopore is formed, and two apopore groups are symmetrical along mixing drum inwall.
In such scheme, be movable adjustable structure between described storage warehouse and dividing strip.
In such scheme, in described storage warehouse, corner is also provided with electronic sensor, carries out the detection of batching accuracy.
Concrete-agitating method, is mainly used in small-size concrete mixing plant, it is characterized in that, described concrete-agitating method comprises:
Carry out preparation before stirring, mixing drum carries out the installment work of thin conduit, choose the thin conduit that caliber only has former thick water pipe 1/2nd, thin conduit and former thick water pipe are all linked in a centrifugal water pump, and share same switch;
Then feed intake in batches, according to the difference of concrete type, set charging time and time delay charging time, when feeding intake, according to the difference of weather condition, the gap of adjustment dividing strip and flat belt, reduces the gap of dividing strip and flat belt, increases the gap of dividing strip and flat belt during fine day when being specially the rainy day;
Open centrifugal water pump switch when carrying out water filling, design water injection time is 1/2nd of former water injection time, starts to stir, utilize the injection of thin conduit to wash away mixing arm during water filling;
Can start after water filling completes to stir concrete.
Principle of the present invention is: on original discharging device, install a thin conduit additional, thin conduit caliber reduces one times than original water pipe caliber, because producer's design discharging device is water outlet on one side, improve the water outlet of rear stirrer both sides, water yield directly doubles, and with larger to the less pressure of Water Flooding Pipeline Diameter in pipe from plug, mixing arm and blade are washed away by water, and concrete not easily condenses on it.
Dividing strip is connected with " extremely " of storage warehouse simultaneously, change " work " into connect, the gap between dividing strip and flat belt can be adjusted, rainy day when producing turns the gap between coarse aggregate dividing strip and flat belt down, its blanking velocity is slowed down, be attached to as much as possible on fine aggregate and brought into mixer stirring by the oblique belt of chevron shaped material loading, thus not easily landing, cut the waste.
Technical advantage of the present invention is:
Structure is simple, with low cost, the basis not changing existing mixer structure realizes reduce water discharging time, increases hydraulic pressure, decrease concrete coagulation, improve concrete-agitating level, decrease unexpected factor risk and waste.
