Description
Technical Field
The invention relates to the field of concrete production, in particular to a liquid weighing device and a weighing system of a concrete mixing plant.
Background
A concrete mixing plant is a combination device for intensively mixing concrete, also called a concrete precast plant. The concrete mixing plant consists of a material storage system, a conveying system, a batching system, a mixing system, a concrete discharging system, a control system and other auxiliary systems. Cement is used as cementing material, and the raw materials of sand stone, water, admixture and the like are mixed and stirred, and finally the mixture is made into concrete which is used as building material to put into construction production. Since the concrete mixing plant has been put into use, it has been playing an important role in the construction and building industry in China, and this is certainly determined by the excellent characteristics of the concrete mixing plant itself.
In actual production, the water in the concrete proportion consists of two parts, one part is water in the sand and the other part is water measured by a water scale. The water is pumped into the water scale by the water pump, and after the metering is completed, the bottom valve of the water scale is opened and the water is discharged into the stirring host. In actual production, the water content of the sand is often changed and is difficult to accurately measure, and when the actual water content of the sand is higher than a preset value, the water amount metered by the water scale is required to be correspondingly reduced in order to ensure accurate water ratio. As this situation usually occurs after the water balance metering is completed, for this purpose, the industry currently adopts the way of "water-locking" of the water balance to realize the water volume locking and subtracting of the water balance: the water discharge valve is closed in advance at the water discharge end section of the water scale, and a certain amount of water is detained in the water scale, so that the water discharge amount of the water scale is reduced, and the accuracy of actual water proportion is ensured. However, the existing water balance adopts a single water discharge port design with a fixed caliber, that is, the water discharge port and the water buckling port are arranged to be the same port, so that in order to ensure water buckling precision, the caliber of the water discharge port (namely, the water buckling port) of the existing water balance is smaller, the water discharge speed is low, the total water discharge time of the water balance is too long, and the production efficiency of the whole equipment is affected. Namely, the existing fixed caliber water discharge mode cannot achieve both water buckling precision and water discharge speed.
