Centrifugal efficient sand crushing device for nodular cast iron

Abstract

The invention discloses a centrifugal efficient sand crushing device for nodular cast iron in the technical field of nodular cast iron. The centrifugal efficient sand crushing device comprises a device outer cover, and supporting feet are arranged at the bottom of the device outer cover; a discharge opening is formed in the center of the bottom of the device outer cover; a feed bin is fixedly arranged at the top of the device outer cover; a bottom discharge opening of the feed bin stretches into an inner cavity of the device outer cover; a centrifugal sand crushing chamber and a driving control chamber are arranged in the inner cavity of the device outer cover; the centrifugal sand crushing chamber is positioned above the driving control chamber; a plane bearing is arranged between the centrifugal sand crushing chamber and the driving control chamber; fixed rod parts are arranged between the outer wall of the driving control chamber and the side wall of the inner cavity of the device outer cover; rotating stirring rods, stirring branched rods, a sand outlet filter screen and a centrifugal rotating shaft are arranged in an inner cavity of the centrifugal sand crushing chamber; and stirring gears, a transmission gear, a centrifugal bevel gear, a driving bevel gear and a driving motor are arranged in an inner cavity of the driving control chamber. The centrifugal efficient sand crushing device for nodular cast iron provided by the invention is efficient and thorough in crushing.

Description

technical field [0001] The invention relates to the technical field of nodular cast iron, in particular to a centrifugal high-efficiency sand crushing device for nodular cast iron. Background technique [0002] In 1981, Chinese nodular iron experts used modern scientific methods to study 513 pieces of ancient Han and Wei iron wares unearthed, and concluded through a large amount of data that nodular graphite cast iron appeared in China during the Han Dynasty. Relevant papers were read at the 18th World Conference on the History of Science and Technology, which caused a sensation in the international foundry and science and technology history circles. International metallurgical history experts verified this in 1987 and believed that this is of great significance for the reclassification of world metallurgical history. 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 ex...
