Description
Technical Field
[0001] This utility model relates to the field of mechanical manufacturing technology, and in particular to an iron sand separation device for casting. Background Technology
[0002] Iron sand is a granular material with iron as its core component. It is usually produced by crushing, screening and magnetic separation of natural iron ore (such as magnetite and hematite), or by recycling and reprocessing iron-containing waste (such as steel slag and iron filings) generated in industrial production.
[0003] During the casting production cleaning process, because castings are composed of multiple sand cores, certain gaps are generated. After the casting is poured, these gaps will form excess iron, which needs to be removed during the cleaning and grinding process. During the cleaning and grinding process, these excess iron pieces fall to the ground through cutting or knocking and mix with dust and sand particles. Sorting is labor-intensive and time-consuming. The existing technology combines vibrating screening and magnetic separation to adsorb iron pieces while screening sand particles. For example, a foundry uses a double-layer magnetic screen. The upper screen separates large sand particles, and the lower magnetic plate adsorbs iron pieces. However, the filter plates are of fixed specifications. Changing to filter plates with different apertures requires modifying the frame or replacing the entire screen plate assembly, which has poor adaptability. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a casting iron sand separation device, which aims to improve the problem that the filter plates in the prior art are of fixed specifications, and that changing the filter plates with different pore sizes requires modifying the frame or replacing the entire set of screen plate assemblies, resulting in poor adaptability.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a casting iron sand separation device, comprising a support, a frame at the top of the support, a replacement mechanism inside the frame for replacing and repairing the grading device, a vibration mechanism at the top of the support for vibrating the frame; the replacement mechanism includes a filter plate inside the frame, pull plates fixedly connected to the four corners of the outer wall of the filter plate, placement grooves at the four corners of the inner wall of the frame, the pull plates slidably connected to the placement grooves, multiple limiting blocks fixedly connected at equal intervals to the top wall of the support, pull rods penetrating the outer walls of the limiting blocks, fixing blocks fixedly connected to the ends of the pull rods, a spring on the outer wall of the pull rods, square grooves on the outer walls of the pull plates, the fixing blocks slidably connected to the square grooves, and a fixing component at the top of the frame.
[0006] As a further description of the above technical solution: The fixing component includes a circular groove, which is formed on the top wall of the fixing block. A spring is provided on the inner bottom wall of the circular groove, and a bolt is threadedly connected to the inner bottom wall of the circular groove.

[0007] As a further description of the above technical solution: The vibration mechanism includes a third spring, which is fixedly connected to the top wall of the bracket. Connecting blocks are fixedly connected to the four corners of the outer wall of the frame. The top of the third spring is fixedly connected to the bottom wall of the connecting blocks. A drive assembly is provided on the top of the bracket.
[0008] As a further description of the above technical solution: The drive assembly includes a motor, which is fixedly connected to the rear side of the top wall of the bracket. The output end of the motor is fixedly connected to a rotating shaft. A support block is fixedly connected to the front side of the middle part of the top wall of the bracket.

A second connecting block is rotatably connected to the end of the crank. A column is rotatably connected to the end of the second connecting block. A connecting plate is fixedly connected to the top of the column. The connecting plate is fixedly connected to the bottom wall of the frame.
[0009] As a further description of the above technical solution: The first spring is located inside the two limiting blocks, and the second spring is located at the bottom of the bolt.

[0012] As a further description of the above technical solution: The bracket has sliding grooves at the four corners of its top wall, and sliders are slidably connected to the inner walls of the sliding grooves. The sliders are fixedly connected to the bottom wall of the fixed block.
[0013] This utility model has the following beneficial effects: 1. In this utility model, the filter plate is slidably positioned in the placement groove of the frame by the pull plates at the four corners. The pull rod pushes the fixing block into the square groove of the pull plate under the action of the spring. Then, the fixing block is fixed on the frame by the bolt compressing the spring, so that the filter plate is stable in the frame. When the filter plate needs to be replaced or repaired, the bolt is loosened, the pull rod is pulled to make the fixing block disengage from the square groove, and the filter plate can be pulled out.

The connecting blocks one at the four corners of the frame compress or stretch the spring three below. The spring three provides elastic support and amplifies the vibration amplitude. The support block stabilizes the rotating shaft, realizes efficient vibration of the frame, enhances the iron sand separation effect, reduces labor intensity, saves labor costs, and improves the efficiency of enterprises.
