Description

Technical Field

[0001] The utility model relates to the technical field of spiral scales, in particular to a spiral scale for kiln bag ash. Background Art

[0002] The spiral scale refers to a weighing feeder, which is a production metering equipment that continuously conveys, dynamically measures and controls the feeding of powder and granular materials. When the material is conveyed from the feed port to the discharge port through the impeller spiral, the electronic weighing device (composed of a weighing lever, a supporting spring, a weighing sensor, etc.) installed under the screw conveyor detects the weight of the material and generates a voltage signal proportional to the load of the weighing lever and sends it to the dynamic weighing instrument. At the same time, the speed sensor installed at the tail of the screw conveyor inputs the speed signal of the conveyor main shaft. The two signals are processed by the dynamic weighing instrument to obtain the instantaneous flow value and the cumulative weight value. In the zinc ash extraction process batching system, a spiral scale is needed to quantitatively discharge the bagged ash entering the kiln.

[0003] Existing spiral scales are usually installed by hoisting. During the weighing process of the spiral scale, it is necessary to ensure that the spiral scale is always in a horizontal posture. The spiral scale will vibrate during use, thereby affecting its angle, which will affect its accuracy in specific use. After its accuracy is affected, as time accumulates, the error will become larger and larger, which may cause losses to the factory, and workers are required to manually perform leveling.
