MEASURING HOPPER USED FOR CAKING LOOSE MATERIALS Russian patent published in 2009 - IPC G01F13/00 

FIELD: engineering industry.

SUBSTANCE: invention refers to means of storage and emptying of caking loose materials and is intended to improve accuracy, stability and reliability of their batching. The effect is provided by the fact that measuring hopper meant for the caking loose materials includes a hollow casing located vertically with an outlet opening provided from below, which is equipped with a cover, as well as an arch destructor which is located in the casing cavity. At that, according to invention, the arch destructor is made in the form of several rigid pins arranged on the inner side of the cover so that they can come into a direct contact with loose material available in the casing. Pins are rigidly fixed on axles which are hinged to inner surface of the cover so that they can rotate, and each pin is equipped with several changeable disk-shaped elements which are installed on pins so that they can move along them and fix their own position. Arch-destructing rigid pins can be either bent or straight. Changeable disk-shaped elements can be made in the form of threaded washers conjugated with rigid pins along threaded surface. Number of rigid pins is chosen depending on the volume of hollow casing as well as depending on the size and shape of particles of material being batched as well as its flowability, caking, and ability to form arch.

EFFECT: simplifying the design of measuring hopper, and providing its versatility i.e. possibility of prompt re-alignment depending on types of caking hard-running materials.
