Technical Field
The invention relates to the technical field of observation of building concrete, in particular to a device capable of observing concrete slump abnormity in real time.
Background
The concrete slump is an important working performance index of concrete, the concrete slump is a key link for controlling the quality of the concrete, the concrete is automatically controlled by a control system in the factory production process of a mixing plant, sand, stones, cement, fly ash, mineral powder, water, additives and the like are delivered to a mixing host machine for mixing after accurate metering and delivery according to actual mixing ratios, the mixed concrete with the appropriate slump is discharged into a concrete collecting hopper through a host machine discharging door, and then is discharged into a concrete mixing transport vehicle through the concrete collecting hopper, and the concrete is transported to a construction site for pouring. In the concrete production process, factors such as the quality difference of sand and stone raw materials, the change of water content, sudden equipment failure and the like can cause the concrete slump to change constantly, even become abnormal. If the slump is abnormal, the quality of the concrete is seriously influenced, and even quality accidents are caused.
There are generally three methods of monitoring slump:
the first is monitored by quality control technical personnel, at first is that it is experimental to do the concrete slump when opening the dish, makes the adjustment according to the test result, and secondly the concrete leaves the factory before the car does the detection, in case discovery slump is unusual, must put in order the car and return the production line and adjust or scrap, both extravagant material, increase cost, waste time and energy again, still work efficiency is low.
And secondly, during normal production, monitoring by an operator of the mixing plant through observing the flowing condition of the concrete in the collecting hopper and a current value displayed by an ammeter in the mixing process, finding out the slump abnormality and immediately informing a technician to adjust the mixing ratio. However, concrete flows in the collecting hopper quickly, so that observation is inconvenient, and concrete slump cannot be judged accurately, and the current value displayed by an ammeter in the stirring process can only be indirectly judged about the approximate slump and is not intuitive by observing the current value, and the current values corresponding to the concrete with different grades and different slump have large difference, and have extremely high requirement on comprehensive quality of operators.
