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 1-4The illustrated feeding protection device for magnesium ingot melting includes a fixed protective enclosure 1. One end of the fixed protective enclosure 1 is provided with a downwardly extending guide plate 8. The other end of the fixed protective enclosure 1 is inserted from top to bottom with a movable protective cover 6. The guide plate 8 and the movable protective cover 6 are staggered. The front, left, and right side plates 7 of the movable protective cover 6 are respectively inserted into the front, left, and right sides of the fixed protective enclosure 1. The front, left, and right sides of the fixed protective enclosure 1 are provided with interconnected slots 19. The outer side of the slots 19 is provided with vertical insertion ports 10. The front, left, and right side plates 7 of the movable protective cover 6 are provided with studs 11 corresponding to the vertical insertion ports 10. The studs 11 are screwed with fastening nuts 12.

[0026] By implementing the above technical solution, when using the magnesium ingot melting feeding protection device, the bottom of the fixed protective plate 1 is first installed to the feeding port of the reactor body. Material is then fed onto the guide plate 8, sliding downwards along it until it reaches the feeding gap between the guide plate 8 and the fixed protective plate 1, completing the feeding operation. Because the guide plate 8 and the movable protective cover 6 are offset, any splashed liquid is blocked by the movable protective cover 6, increasing the safety of the feeding. The vertically adjustable movable protective cover 6 allows for adjustment of its top blocking height as needed. Without affecting the feeding onto the guide plate 8, the height of the movable protective cover 6 is lowered as much as possible to increase the protective effect.

[0027] In this embodiment, the fixed protective enclosure 1 has shaft holes on both sides, and the guide plate 8 has rotating shafts 5 on both sides of its outer end that are rotatably connected to the shaft holes. The fixed protective enclosure 1 is equipped with a drive mechanism that pushes the guide plate 8 to swing around the rotating shafts 5. With this configuration, the drive mechanism can push the guide plate 8 to swing around the rotating shafts 5, thus adjusting the tilt angle of the guide plate 8.

[0028] In this embodiment, the driving mechanism includes a cylinder 4 mounted outside the fixed protective enclosure 1. The cylinder shaft of the cylinder 4 passes through the fixed protective enclosure 1 and extends into it. A connecting rod 17 is connected to the inner end of the cylinder shaft. Protrusions 16 are provided on both sides of the connecting rod 17. A push block 13 extending obliquely downwards away from the cylinder 4 is provided at the bottom of the guide plate 8. A first elongated hole 18 penetrating from front to back is provided on the push block 13. Second elongated holes 15 are provided on both sides of the first elongated hole 18, which slide and engage with the protrusions 16. In use, when the cylinder shaft extends or shortens, the protrusions 16, guided by the second elongated holes 15, push the push block 13 vertically due to its oblique extension, thereby causing the guide plate 8 to rotate. A sealing bushing is used to connect the cylinder shaft to the side wall of the fixed protective enclosure 1 to increase sealing performance.

[0029] In this embodiment, a reinforcing rib 14 is provided between the side of the pusher block 13 facing away from the cylinder 4 and the bottom surface of the guide plate 8. This arrangement increases the strength of the pusher block 13.

[0030] In this embodiment, a plurality of trapezoidal grooves 9 are arranged along the width direction on the guide plate 8. The arrangement of multiple trapezoidal grooves 9 enhances the downward guiding effect.

[0031] In this embodiment, a connecting flange 2 is provided at the lower end of the fixed protective enclosure 1, and the connecting flange 2 is provided with mounting holes 3. With this arrangement, the feeding protection device for melting magnesium ingots is installed to the inlet of the reactor body using the connecting flange 2.

[0032] In this embodiment, at least two studs 11 are provided on the front, left, and right sides of the movable protective cover 6. The two studs 11 are arranged vertically to increase the fixing effect on the movable protective cover 6.

[0033] 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.

[0034] 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.

[0035] 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.
