Pretreatment crushing device for cast iron waste parts

Abstract

The invention discloses a pretreatment crushing device for cast iron waste parts. The pretreatment crushing device for the cast iron waste parts comprises a device main body and a large rotating wheel; a feed hopper is riveted on the upper end surface of the device main body; a rotating shaft is rotationally arranged in the feed hopper; an agitator is arranged on the rotating shaft in a sleeving mode; a static jaw plate is riveted on one side of the inner wall of the device main body; a movable jaw plate is movably arranged on the other side of the inner wall of the device main body; and a crushing cavity is reserved between the static jaw plate and the movable jaw plate. According to the pretreatment crushing device for the cast iron waste parts, the movable jaw plate reciprocates leftwards and rightwards, waste materials in the crushing cavity is continuously impacted and crushed, the crushing operation is completed by matching with the static jaw plate, the volume of waste iron is further reduced, a fan is additionally arranged, a great wind force is generated in the process of dropping the waste materials, the dropped material is subjected to winnowing, fine substances such asresidues, slag inclusion and the like are winnowed and enter into a waste material winnowing groove, the separation task is completed, the purity of subsequent molten iron is guaranteed, different working conditions are applicable, and a better application prospect is brought.

Description

technical field [0001] The invention relates to the field of pretreatment of iron castings, in particular to a pretreatment and crushing device for waste iron castings. Background technique [0002] When these scrap iron castings are melted and recycled in an induction furnace, these scrap iron castings take up a lot of space in the electric furnace, so that there are few magnetic conductors and large gaps in the melting furnace, which makes the speed of melting molten iron when melting and recycling scrap cast iron It is very slow but consumes a lot of electric energy. Therefore, in order to solve the above problems, it is generally necessary to process and crush the scrap iron before the melting process; the existing crushing device has many disadvantages. It will cause blockage during the process and affect the crushing; after crushing, it is easy to produce small and useless residues, which will affect the purity of the iron when thrown into the electric furnace together...

Problems solved by technology

[0002] When these scrap iron castings are melted and recycled in an induction furnace, these scrap iron castings take up a lot of space in the electric furnace, so that there are few magnetic conductors and large gaps in the melting furnace, which makes the speed of melting molten iron when melting and recycling scrap cast iron It is very slow but consumes a lot of electric energy. Therefore, in order to solve the above problems, it is generally necessary to process and crush the scrap iron before the melting process; the existing crushing device has many disadvantages. It will cause blockage during the process and affect the crushing; after crushing, it is easy to produce small and useless residues, which will affect the purity of the iron when thrown into the electric furnace together with the waste, and bring certain adverse effects in the process of processing. Therefore, we propose a cast iron Waste pretreatment shredder
