Steel crushing device

Abstract

The invention relates to waste steel recycling equipment, and provides a steel crushing device which comprises a cutting mechanism in a machine, a crusher frame and an elastic shockproof structure at the bottom. The cutting mechanism comprises two cutting wheels, cutting blades are arranged on the surfaces of the cutting wheels, and supporting rods are arranged at the tail ends of bearings of the two cutting wheels; the crusher frame comprises a feed port sliding plate, a feed port sliding plate supporting rod, an anti-rebound plate, an shock absorption layer and an external steel plate layer; and the bottom elastic shock absorption structure comprises three parts, namely an upper-layer bearing plate, a lower-layer bearing plate and a middle spring vibration isolator. The steel crushing device is designed on the basis of the concept of shock absorption and noise reduction, the bottom shock absorption structure and the shock absorption layer in a crusher are formed, noise is greatly reduced when the machine runs, meanwhile, the shapes of the cutting blades on the cutting wheels can be matched with each other, and waste steel is cut to be smaller.

Description

technical field [0001] The invention relates to waste and old iron and steel recycling equipment, more specifically, to a steel crushing device. Background technique [0002] Steel is a metal material used in a huge amount in today's society, and the development of society cannot do without the production of steel. However, the steel manufacturing industry is a high-energy-consuming industry, and its annual energy consumption can account for 15% of the country's total annual energy consumption. With the progress of society, the state has formulated a policy of green development, which requires the steel industry to change its development thinking and achieve energy conservation and emission reduction. As a feasible and economical development method, steel recycling has formed a relatively mature market. [0003] When the existing scrap steel crusher is running, it produces huge noise. The production workers need to wear sound-proof headphones to work. At the same time, the...

Problems solved by technology

[0003] When the existing steel scrap crusher is running, it produces huge noise. The production workers need to wear sound-proof headphones to work. At the same time, the huge vibration of the machine may cause the internal structure of the machine to loosen, and may also cause damage to the surrounding buildings, causing production safety. question
