Embodiment Construction

[0021] The embodiment shown in each figure is as follows: a special crusher for waste iron castings. The crusher has a fixed jaw plate 2 fixed on the frame 1 and a movable jaw plate 6 fixed on the frame 1 that can swing around the swing shaft 4 . The movable jaw plate 6 is movably connected with the hydraulic cylinder 7 . There are semi-cylindrical bevel teeth I3 and semi-cylindrical bevel teeth II5 on the fixed jaw plate 2 and the movable jaw plate 6 respectively. Its characteristics are:

[0022] On the fixed jaw plate 2, three rows of semi-cylindrical bevel teeth I3 are arranged in parallel from top to bottom. There is a gap L8 of the same size between the semi-cylindrical bevel teeth I3 in each row. Both the first row and the third row are provided with four semi-cylindrical bevel teeth I3, and the four semi-cylindrical bevel teeth I3 in the first and third rows are aligned longitudinally. The second row is provided with three semi-cylindrical bevel teeth I3. The thre...

Abstract

The invention discloses a special crusher for waste casting iron pieces, comprising a rack, a fixed jaw plate, a swinging shaft, a movable jaw plate, a hydraulic cylinder, semi-cylindrical conical teeth I and semi-cylindrical conical teeth II, wherein three rows of semi-cylindrical conical teeth I are arranged in parallel from top to bottom on the fixed jaw plate; and a gap L with same size is arranged between every two rows of semi-cylindrical conical teeth I. Four rows of same semi-cylindrical conical teeth II are arranged in parallel from top to bottom on the movable jaw plate; and a gap with same size is arranged between every two rows of semi-cylindrical conical teeth II. When the movable jaw plate and the fixed jaw plate of the crusher are meshed, the four rows of semi-cylindrical conical teeth II on the movable jaw plate and the three rows of semi-cylindrical conical teeth I on the fixed jaw plate are arranged horizontally at intervals. The invention provides the special crusher for the waste casting iron pieces, which has the functions of extrusion and shearing. According to the crusher, the branch-shaped waste casting iron pieces formed by casting heads and runners and the like can be quickly and effectively extruded and sheared into small casting iron blocks; and since the small casting iron blocks are arranged closely in an electric induction furnace, the occupied space is small, the melting can be quick and the power consumption is lower.

Description

technical field [0001] The invention relates to a crusher, in particular to a crusher specially used for waste iron castings in the foundry industry with extrusion and shearing functions. Background technique [0002] In the foundry industry, when pouring the molten iron model, in addition to obtaining iron castings with specific shapes, many dendritic waste iron castings composed of pouring risers and various runners are obtained. When these waste iron castings are melted and recycled in an induction electric furnace, these waste iron castings take up a lot of space in the electric furnace. In this way, there are few magnetic conductors and large gaps in the melting furnace. This makes the speed of melting molten iron very slow but the amount of electric energy used when melting recycled waste cast iron. [0003] In order to solve the above-mentioned problems that the melting speed of molten iron is slow and the power consumption is very large. Both adopt the method of c...
