Technical Field

[0001] The utility model relates to the technical field of lime production, in particular to a lime production metering device. Background Art

[0002] Lime is an air-hardening inorganic cementitious material with calcium oxide as the main component, which is obtained by calcining raw materials such as limestone, dolomite or chalk. It is the earliest cementitious material used by humans. Lime is hard, earthy, and opaque. It includes quicklime and slaked lime. Due to its wide distribution of raw materials, simple production process and low cost, it is widely used in civil engineering. When producing lime, it needs to be measured and weighed.

[0003] The Chinese authorized announcement number CN217560771U is a metering and conveying device for active lime production. A weighing box is arranged on the top of the bottom shell of the metering and blanking device, a load-bearing sensor is arranged between the weighing box and the bottom shell, and a blanking frame is arranged on the top of the weighing box. The outer side of the blanking frame is connected to the bottom shell through a support frame. The weighing box and the blanking frame are respectively provided with movable guide plates and movable support plates, so that the weighing box presses down the weighing sensor when subjected to force, and the weight of the weighing box and the active lime inside is obtained by the weighing sensor. The weight of the active lime inside the weighing box can be calculated by subtracting the original weight of the weighing box.
