Technical Field
The utility model belongs to the technical field of construction equipment, concretely relates to impeller feed ware for weighing hopper.
Background
The concrete mixing plant needs to measure (weigh) the raw materials for forming the concrete, such as cement, fly ash, gravel, water, additives and the like, and then supply the raw materials into a mixing tank according to certain proportioning requirements to mix and form the qualified concrete so as to ensure the quality of various construction projects. The material feeder for concrete mixing plant consists of weighing hopper, weighing sensor and weighing screw mechanism. The cement is automatically fed into the measuring hopper from the cement (material) bin, and is fed into the stirring cylinder by the measuring screw according to a certain proportion requirement, and is fully stirred and mixed with various raw materials to form a concrete finished product.
The existing material feeding device has a self-flowing phenomenon, namely when the metering screw rotates, cement is pushed by the screw to flow outwards and flows, namely the actual flow rate of the cement is greater than that of the screw. The condition for forming self-flow is that the position of materials such as cement, fly ash and the like is higher than the position of the metering spiral outlet. As long as the materials have a certain potential energy difference, the self-flowing phenomenon cannot be avoided, and the layout of the concrete mixing plant cannot have the potential difference and even has a larger potential difference, so the self-flowing phenomenon cannot be eliminated. In addition, friction, adhesion, etc. all play an essential role. Particularly, under the dynamic condition, the self-flowing phenomenon is more complex when the metering screw mechanism rotates, and is influenced by a plurality of fixed and unfixed factors, and the self-flowing speed is variable and unstable and is a random factor.
