Problems solved by technology

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

Embodiment 1

[0022] Example 1: Refer to the attached figure 1 . Dust ring for cone crusher, the material of said dust ring is cast iron, and the range of composition and weight percentage of said cast iron material is: 91.2% iron, 4.8% graphite and 4% silicon. Its production method: add 4.8% graphite and 4% silicon in order to 91.2% molten iron to fully melt the molten iron, then cast in the sand mold cavity of the dustproof ring, and then cool.

Embodiment 2

[0023] Example 2: Refer to the attached figure 1 . Dust ring for cone crusher, the material of the dust ring is cast iron, and the composition and weight percentage content range of the cast iron material is: 92.6% iron, 4.4% graphite and 3% silicon. Its production method: add 4.4% graphite and 3% silicon in order to 92.6% molten iron to make it fully melted in the molten iron, and then cast it in the sand mold cavity of the dustproof ring, and then cool.

Embodiment 3

[0024] Example 3: Refer to the attached figure 1 . The dustproof ring for cone crusher is made of cast iron, and the composition and weight percentage content range of the cast iron material is: 92% iron, 4.6% graphite and 3.4% silicon. Its production method: in 92% molten iron, add 4.6% graphite and 3.4% silicon in sequence to make it fully melted in the molten iron, and then cast in the sand mold cavity of the dust ring, and then cool.

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 dustproof ring for a cone crusher with self-sealing and self-lubricating functions, belonging to the field of metal dustproof ring manufacturing. Background technique [0002] The existing dustproof ring for cone crusher is made of cast iron. Its shortcomings: in the process of combining the sealing surface of the dust 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 abrasion, but also the sealing joint surface is easy to wear and lose. Loss of sealing function. Summary of the invention [0003] Design purpose: to avoid the deficiencies in the background technology, 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 design objectives, the present invention selects the following additional materials as additional materials based ...
