Description

Technical Field

[0001] The utility model relates to the technical field of cement production, in particular to an anti-clogging cement raw material rotor scale. Background Art

[0002] A rotor scale is a device used to measure the weight of an object. It uses a special technical principle to determine the mass of an object by detecting the rotation of the rotor. This weighing method is characterized by high precision, stability and reliability.

[0003] The rotor is composed of a series of blades, which together with the disc wall form a grid of rotating spaces. When feeding, the material enters these spaces from the feed port and is discharged from the discharge port as the rotor rotates. At this time, half of the disc has material and the other half does not, relative to the fulcrum, causing the two semicircles of the disc to lose balance relative to the fulcrum. The weighing sensor is subjected to a force that is proportional to the weight of the material in the disc. When an object is placed on a freely rotating rotor, its mass will affect the rotational inertia of the rotor. When the rotor rotates, the object will generate an outward centrifugal force that is proportional to the mass of the object. At the same time, as the object moves up and down, its gravity will also affect the rotational speed of the rotor. By measuring the balance between these two forces, the mass of the object can be determined.

[0004] Nowadays, rotor scales are important equipment in cement production. When in use, the feed port of the rotor scale is connected to the discharge pipe, and the discharge port of the rotor scale is connected to the chute of the kiln elevator. However, this operation method has certain defects, that is, when the feed amount is large, it is easy to cause the rotor scale to be blocked. Utility Model Content
