This magnesium scrap remelting device adopts a segmented feeding mechanism, which changes the transmission from horizontal to vertical. The magnesium scrap is fed into the middle position of the feeding pipe to increase the dispersion effect of the feeding. The feeding accumulates on the gate plate and then the gate plate is opened to concentrate the magnesium scrap into the melting furnace body, realizing multiple feeding and increasing the remelting effect.

[0006] To achieve the above objectives, this utility model provides a magnesium scrap remelting device, including a melting furnace body and a feeding mechanism disposed at the upper end of the melting furnace body.

Detailed Implementation

[0023] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0024] In this utility model, unless otherwise stated, directional terms such as "up, down, left, right, front, back, inside, outside" in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as a limitation on the term.

[0025] See Figure 1-3The magnesium scrap remelting device shown includes a melting furnace body 1 and a feeding mechanism located at the upper feed inlet of the melting furnace body 1. The feeding mechanism includes a connecting pipe 2, a control pipe 3 and a feeding pipe 4 arranged sequentially from bottom to top. A gate 8 is provided on one side of the control pipe 3. A drive unit is provided outside the control pipe 3 to drive the gate 8 to open or close the control pipe 3. An inlet pipe 24 is provided on the side of the feeding pipe 4. A screw feeder is connected to the outside of the inlet pipe 24. The front end of the screw feeder passes through the inlet pipe 24 and extends into the feeding pipe 4.

[0026] Through the implementation of the above technical solution, the magnesium scrap remelting device adopts a segmented feeding mechanism, consisting of three sections: a detachable connecting pipe 2, a control pipe 3, and a feeding pipe 4. The transmission of magnesium scrap is changed from horizontal to vertical. By inserting the front end of the screw feeder through the inlet pipe 24 and into the feeding pipe 4, the feed is fed to the middle position of the feeding pipe 4, increasing the dispersion effect of the feed. The feed accumulates on the gate plate 8 before the gate plate 8 is opened, concentrating the magnesium scrap into the melting furnace body 1, achieving multiple feedings and increasing the remelting effect. The melting furnace body 1 in this invention can be an electric furnace, and a stirring device can also be installed inside it; technicians can choose according to their needs.

[0027] When magnesium shavings accumulate to a certain amount on the gate 8, the gate 8 is opened to feed material downwards and melt it. After melting for a period of time, the gate 8 is opened again to feed magnesium shavings downwards. The newly fed magnesium shavings can enter the molten material and be encapsulated, increasing the heat transfer effect and thus increasing the melting effect.

[0028] In this way, multiple feedings are performed to increase the remelting effect, and the feeding does not need to be done all at once, thus increasing the melting efficiency.

[0029] In this embodiment, the side of the control tube 3 is provided with a rectangular insertion hole that slides with the gate plate 8; a drive plate 10 is fixedly connected to the outer end of the gate plate 8, and ear plates 9 are provided on both sides of the control tube 3. A cylinder 7 is installed on the ear plate 9, and the cylinder shaft of the cylinder 7 is connected to the end of the drive plate 10. Two cylinders 7 are symmetrically arranged. The extension and retraction of the two cylinders 7 pushes the drive plate 10 to move laterally, thereby driving the gate plate 8 to slide and insert into the insertion hole to close or open the control tube 3.

[0030] In this embodiment, an extended end cap 11 is provided at the upper end of the feed pipe 4; the extended end cap 11 is connected to the feed pipe 4 by a plurality of first bolts 18. The extended end cap 11 can be simply a cover for easy maintenance after opening, or multiple nozzles can be installed on the extended end cap 11 for spraying cleaning liquid onto the inner wall of the feed mechanism to clean the inner wall of the feed mechanism.

[0031] In this embodiment, the screw feeder includes a feeding pipe 5 and a spiral blade 20 installed inside the feeding pipe 5. An end plate 15 is mounted to the rear end of the feeding pipe 5 via multiple second bolts 19. A drive motor 17 is mounted on the end plate 15, and the shaft 21 of the drive motor 17 passes through the spiral blade 20. A feeding port 16 is provided on the upper side of the rear end of the feeding pipe 5. With this configuration, magnesium shavings enter through the feeding port 16, and under the drive of the drive motor 17, the spiral blade 20 rotates, conveying the magnesium shavings to the front end of the feeding pipe 5 where they fall.

[0032] In this embodiment, a guide tube 22 is provided at the front end of the feeding pipe 5. The guide tube 22 is inserted and engaged with the inlet pipe 24, and the front end of the spiral blade 20 is aligned with the front end of the guide tube 22. This arrangement, with the guide tube 22 acting as an extension, shifts the magnesium shavings landing point towards the middle of the feeding pipe 4, ensuring the magnesium shavings land in the center of the feeding pipe 4. This prevents excessive accumulation of magnesium shavings at the edge of the gate 8, which would otherwise lead to poor magnesium shaving dispersion.

[0033] In this embodiment, the inner wall of the feed pipe 4 is provided with a bearing seat 23 that rotatably engages with the shaft 21. This arrangement, using an elongated shaft 21 in rotatable engagement with the bearing seat 23, increases the rotational stability of the shaft 21.

[0034] In this embodiment, to further provide a connection method between the pipes, the connecting pipe 2 is connected to the melting furnace body 1 through a first flange 6, the connecting pipe 2 is connected to the material control pipe 3 through a second flange 13, the material control pipe 3 is connected to the feed pipe 4 through a third flange 14, and the inlet pipe 24 is connected to the screw feeder through a fourth flange 12.

[0035] In this embodiment, the connecting pipe 2, the material control pipe 3, and the feed pipe 4 are all square pipes. This arrangement allows for better cooperation with the rectangular gate 8.

[0036] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0037] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0038] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
