Embodiment 1

[0022] Embodiment 1: with reference to accompanying drawing 1. A dust-proof ring for a cone crusher, the material of the dust-proof ring is cast iron, and the composition and weight percentage range of the cast iron material are: 91.2% iron, 4.8% graphite and 4% silicon. Its production method: add 4.8% graphite and 4% silicon in turn to 91.2% molten iron to make it fully melted in the molten iron, then cast it in the mold cavity of the dust-proof ring, and cool it down.

Embodiment 2

[0023] Embodiment 2: with reference to accompanying drawing 1. A dust-proof ring for a cone crusher, the material of the dust-proof ring is cast iron, and the composition and weight percentage range of the cast iron material are: 92.6% iron, 4.4% graphite and 3% silicon. Its production method: add 4.4% graphite and 3% silicon in turn to 92.6% molten iron to make it fully melted in the molten iron, then cast it in the molding sand mold cavity of the dust-proof ring and cool it down.

Embodiment 3

[0024] Embodiment 3: with reference to accompanying drawing 1.

Abstract

The invention relates to a scraper seal for a conical crusher with self-sealing self-lubricating function, material quality of the scraper seal is cast iron, the content range of the components and cast iron of the cast iron material is that iron 91.2-92.6%, graphite 4.4-4.8% and silicon 3-4%. The scraper seal has the advantages that first, the adding of graphite leads a sealing ring which is casted not only have the function of lubricating and self-sealing, but also has the function of resisting acid, resisting alkali, resisting the corrosion of organic solvent, resisting wear, resisting high temperature and resisting cracks, second, the adding of silicon leads sealing ring which is casted to have double characters of metal and ceramic element, and the integral property of the casted sealing ring is improved.

Description

technical field [0001] The invention relates to a dust-proof ring for a cone crusher with self-sealing and self-lubricating functions, belonging to the field of metal dust-proof ring manufacturing. Background technique [0002] The existing dust-proof ring for the cone crusher is made of cast iron. Its disadvantages: In the process of combining the sealing surface of the dustproof ring with the sealing joint surface of the broken wall, the two form a rigid contact, which not only has a large friction coefficient and large wear loss, but also the sealing joint surface is very easy to wear and tear. Loss of sealing function. Contents of the invention [0003] Design purpose: to avoid the deficiencies in the background technology, and to design a dust-proof ring for cone crushers with wear-resistant, self-lubricating and self-sealing functions. [0004] Design scheme: In order to achieve the above-mentioned design purpose, the present invention selects the following additio...
