Centrifugal efficient sand crushing device for nodular cast iron

Abstract

The invention discloses a centrifugal efficient sand crushing device for nodular cast iron, and relates to the technical field of sand crushing devices. The centrifugal efficient sand crushing device comprises a sand crushing device body, a device shell, a dustproof bin cover, a centrifugal sand crushing cavity, a sand discharge filter screen and a stabilizing and protecting ring, wherein the dustproof bin cover is arranged at the top of the sand crushing device body, the centrifugal sand crushing cavity is formed below the dustproof bin cover, the sand discharge filter screen is fixedly mounted on the outer ring of the centrifugal sand crushing cavity, and a device shell is fixedly mounted on the outer side of the centrifugal sand crushing cavity. According to the centrifugal efficient sand crushing device for the nodular cast iron, stirring rods are rotated to drive stirring branch rods to rotate to crush and stir sand blocks, and the two groups of stirring branch rods move relatively under the action of the same transmission gear, so that the stirring branch rods can stir and crush the sand blocks at all corners in the centrifugal sand crushing cavity in all directions, and the sand blocks are prevented from staying at dead angles; and the centrifugal sand crushing cavity rotates, so that sand blocks fallen into the centrifugal sand crushing cavity actively collide with the stirring branch rods under the action of centrifugal force, and the stirring effect is further improved.

Description

technical field

[0001] The invention relates to a sand crushing device, and relates to the technical field of sand crushing devices, in particular to a centrifugal high-efficiency sand crushing device for ductile iron. Background technique

[0002] Ductile cast iron is a high-strength cast iron material developed in the 1950s. Its comprehensive performance is close to that of steel. It is based on its excellent performance that it has been successfully used to cast some complex stress, strength, toughness, and wear resistance. For parts with high performance requirements, nodular cast iron has rapidly developed into a cast iron material that is second only to gray cast iron and is widely used. Ductile cast iron obtains spherical graphite through spheroidization and inoculation treatment, which effectively improves the mechanical properties of cast iron, especially the plasticity and toughness, so as to obtain higher strength than carbon steel. There is a large amount of old ...
