Pig iron crusher capable of being used for crushing large cast iron

Abstract

The invention relates to a pig iron crusher capable of being used for crushing large cast iron. The upper end of a casing is provided with a feeding port, the lower end of the casing is provided witha discharging port, the casing is provided therein with a fixed pressure plate and a dynamic pressure plate, the upper end of the fixed pressure plate is hinged with the casing, the lower end of the dynamic pressure plate is hinged with the casing, the fixed pressure plate is provided thereon with a plurality of fixed pressure blocks, the plurality of fixed pressure blocks are evenly arranged along the height direction of the fixed plate, an adjusting device is arranged on the casing and corresponds to the lower end of the fixed pressure plate, the dynamic pressure plate, being a curved plate,has its lower end hinged with the casing, the middle portion of the dynamic plate is hinged with the piston rod of a hydraulic cylinder, and the upper end of the dynamic plate is suspended, the dynamic pressure plate is provided thereon with a plurality of dynamic pressure blocks, the dynamic pressure blocks are arranged opposite to the fixed pressure blocks, and the hydraulic cylinder is arranged on the casing and connected to a hydraulic pump station arranged outside the casing. The hydraulic cylinder is utilized to push the dynamic pressure blocks and the fixed pressure blocks to extrude alarge cast iron piece, and crushing of the large cast iron piece is realized by extrusion.

Description

technical field [0001] The invention belongs to the technical field of crushing equipment for recycling scrap metal, and in particular relates to a pig iron crusher which can be used for crushing large pieces of cast iron. Background technique [0002] At present, large iron castings on the market, such as disassembled diesel engine casings, disassembled gearbox casings, reducer casings, cast iron radiators, cast iron briquettes, etc., when recycling, usually need to recycle the recycled cast iron However, large iron castings are usually large in size and heavy in weight. Due to the limitation of the size of the melting furnace mouth, large iron castings cannot be directly put into melting. Therefore, foundries generally do not recycle such iron castings. Or give priority to recycling cast iron after manual crushing. [0003] At present, there are mainly two types of crushing of large iron castings in the prior art, one is cutting by a cutting machine, and the other is to u...

Problems solved by technology

[0002] At present, large iron castings on the market, such as disassembled diesel engine casings, disassembled gearbox casings, reducer casings, cast iron radiators, cast iron briquettes, etc., when recycling, usually need to recycle the recycled cast iron However, large iron castings are usually large in size and heavy in weight. Due to the limitation of the size of the melting furnace mouth, large iron castings cannot be directly put into melting. Therefore, foundries generally do not recycle such iron castings. Or give priority to recycling cast iron after manual crushing

[0003] At present, there are mainly two types of crushing of large iron castings in the prior art, one is cutting by a cutting machine, and the other is to use a heavy hammer to crush large iron castings to within 400mm. For cutting and crushing by a cutting machine, the cutting work The time is long, the waste of human resources is serious, and the safety factor is very low

For heavy hammer crushing, the heavy hammer is noisy, high energy consumption, takes up a lot of labor resources, and has a lot of dust, which does not achieve the effect of environmental protection and safe production.

The above methods have high energy consumption, low production capacity, and are not environmentally friendly
