Description

Technical Field

[0001] This application relates to the technology of iron powder feeding for alloy casting, and more particularly to an iron powder feeding device. Background Technology

[0002] During the production of ferroalloy casting, iron powder is generated in multiple stages such as crushing, screening, and dust removal. The composition of the iron powder is the same as that of the cast ferroalloy blocks, and it can be recycled.

[0003] In existing technology, iron powder is placed at the bottom of a continuously circulating casting mold, and then molten iron is poured into the mold, causing the iron powder to melt into the molten iron and be cast into alloy blocks for recycling. However, existing iron powder distribution devices struggle to continuously distribute iron powder to the circulating casting mold during production. Furthermore, during the distribution process, iron powder is easily scattered onto the side walls of the casting mold. Utility Model Content

[0004] This application provides an iron powder feeding device to solve the problems of existing iron powder feeding devices having difficulty in continuously feeding the moving casting mold, and the problem that iron powder is easily scattered on the side wall of the casting mold during feeding.

[0005] This application provides an iron powder feeding device, including a feeding cylinder. The feeding cylinder is mounted above a casting mold via a frame. The feeding cylinder is rotatably connected to the frame and driven by a drive mechanism installed on the side. The arc-shaped wall of the feeding cylinder is composed of spaced mesh plates and baffles. When the feeding cylinder rotates along the conveying direction of the casting mold, the baffles can cyclically block the upper part of the side wall. The iron powder in the feeding cylinder falls into the casting mold from the mesh plate between the two baffles.

[0006] Optionally, a feed cylinder is inserted into one side of the fabric cylinder and fixed concentrically therewith. The feed cylinder is connected to the hopper through a discharge pipe. The feed cylinder is a mesh cylinder and is rotatably connected to the discharge pipe.

[0007] Optionally, a screw conveyor for controlling the discharge speed is installed inside the discharge pipe.

[0008] Optionally, the upper part of the fabric tube is provided with an arc-shaped cover, which is fixed to the frame.

[0009] The iron powder feeding device provided in this application involves loading iron powder into a feeding cylinder. As the cylinder rotates, the iron powder exits from the mesh plate and falls into the casting mold, enabling continuous iron powder feeding during production. The spaced mesh plates and baffles coordinate the rotation speed of the feeding cylinder with the movement speed of the casting mold. This allows the baffles to block the iron powder from falling onto the side walls of the casting mold during discharge, improving the accuracy of iron powder feeding. Attached Figure Description

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.

[0017] like Figures 1-3 As shown, one embodiment of this application provides an iron powder feeding device, including a feeding cylinder 4. The feeding cylinder 4 is set above the casting mold 1 via a frame 3. The feeding cylinder 4 is rotatably connected to the frame 3 and driven by a drive mechanism 5 installed on the side end. The arc-shaped wall of the feeding cylinder 4 is composed of spaced mesh plates 6 and baffles 7. When the feeding cylinder 4 rotates along the conveying direction of the casting mold 1, the baffles 7 can cyclically block the top of the side wall 2. The iron powder in the feeding cylinder 4 falls into the casting mold 1 from the mesh plate 6 between the two baffles 7.

[0018] In use, the casting mold 1 is fixed sequentially on the alloy casting conveyor and moves cyclically along the production line, while the material distribution cylinder 4 is positioned before casting. Simultaneously with the casting mold 1, the material distribution cylinder 4 is rotated synchronously by the drive mechanism 5, causing the iron powder inside the cylinder 4 to fall from the screen plate 6 into the casting mold 1. The rotational speed of the material distribution cylinder 4 is adjusted by the drive mechanism 5 according to the arc length of the screen plate 6, ensuring that the movement speed of the screen plate 6 matches that of the casting mold 1. As the casting mold 1 moves past the material distribution cylinder 4, the baffle 7 rotates synchronously, precisely blocking the iron powder from falling from the screen plate 6 into the casting mold 1 and preventing it from landing on the side wall 2.

[0019] In this embodiment, iron powder is loaded into the feeding cylinder 4. The rotating feeding cylinder 4 discharges the iron powder from the mesh plate 6 into the casting mold 1, enabling continuous iron powder distribution to the casting mold 1 during production. The spaced mesh plates 6 and baffles 7 coordinate the rotation speed of the feeding cylinder 4 with the moving speed of the casting mold 1. This allows the baffles 7 to block the iron powder from falling onto the side wall 2 of the casting mold 1 during discharge, improving the accuracy of iron powder distribution.

[0020] In one possible implementation, a feed cylinder 8 is inserted into one side of the fabric cylinder 4 and fixed concentrically thereto. The feed cylinder 8 is connected to the hopper 10 through a discharge pipe 9. A discharger is installed at the lower end of the hopper 10. The feed cylinder 8 is a mesh cylinder and is rotatably connected to the discharge pipe 9.

[0021] Iron powder is loaded into hopper 10, and then continuously fed into feed cylinder 8 through feed pipe 9. Feed cylinder 8 replenishes iron powder into feed cylinder 4 as it rotates synchronously with distribution cylinder 4. The iron powder is distributed twice through feed cylinder 8 and distribution cylinder 4, resulting in a more even distribution within casting mold 1.

[0022] In one possible implementation, a screw conveyor 12 for controlling the discharge speed is installed inside the discharge pipe 9.

[0023] The screw conveyor 12 can control the discharge speed and also achieve the effect of continuous feeding into the feed cylinder 8.

[0024] In one possible implementation, the upper part of the fabric tube 4 is provided with an arc-shaped cover 11, which is fixed to the frame 3.

[0025] The arc-shaped cover 11 covers the mesh plate 6 above the fabric cylinder 4, reducing the amount of impurities entering the fabric cylinder 4.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
