Description

Technical Field

[0001] This utility model relates to the field of magnesium product processing, specifically to a magnesium material preheating and feeding device. Background Technology

[0002] Magnesium smelting and processing is the core process in magnesium alloy production, involving five major steps: "furnace loading, melting, refining, settling, and casting," as well as supporting equipment and temperature control systems.

[0003] During the charging process, the existing method is to directly put the magnesium material in the furnace into the smelting furnace. The temperature difference between the magnesium material and the smelting furnace will cause an excessive reaction on the surface of the magnesium material, generating too many impurities.

[0004] For example, patent CN215251090U describes an automatic alloy feeder for an electroslag furnace, including a frame, a hopper supported by at least three weighing sensors on the frame, a discharge device installed at the bottom of the hopper, a feeding conveyor belt installed on the frame below the discharge end of the discharge device, the output end of the feeding conveyor belt extending outward, a feeding driver provided between the feeding conveyor belt and the frame; and a feeding funnel installed on the frame at the output end of the feeding conveyor belt.

[0005] The automatic alloy feeder for the electroslag furnace does not have a preheating structure at the feeding conveyor belt position. If this feeder is used to feed magnesium material, the aforementioned problems caused by temperature difference will occur. Utility Model Content

[0006] The purpose of this invention is to provide a magnesium material preheating and feeding device that can preheat magnesium material during the feeding and conveying process, thereby avoiding excessive reactions caused by excessively low magnesium material temperature during the feeding process and affecting the processing effect.

[0007] To achieve the above objectives, this utility model provides a magnesium material preheating and feeding device, which includes a horizontally placed preheating cylinder. A perforated feeding conveyor belt is transversely arranged inside the preheating cylinder. Multiple sets of radially extending movable frames are symmetrically arranged on both sides of the perforated feeding conveyor belt on the preheating cylinder. An electric heating rod is installed at the inner end of the movable frame, and a driving mechanism is connected to the outer end of the movable frame to drive it to move along the radial direction of the preheating cylinder.

[0008] Preferably, the movable frame includes a long wedge-shaped block disposed at the outer end, and a plurality of rods that slide through the preheating cylinder are fixedly connected to the inner side of the long wedge-shaped block. The inner end of the rod is provided with a through hole that can insert the heating rod, and a spring is sleeved on the rod between the long wedge-shaped block and the preheating cylinder.

[0009] Preferably, the driving mechanism includes a driving ring coaxially arranged with the preheating cylinder, L-shaped support frames at both ends of the driving ring, a rotating ring fixed to the end of the L-shaped support frame and rotating on the outer wall of the preheating cylinder, an annular groove corresponding to the rotating ring on the outer wall of the preheating cylinder, and a plurality of driving wedges corresponding one-to-one with the elongated wedges on the inner side of the driving ring, the wedge surfaces of the elongated wedges and the driving wedges being in contact with each other.

[0010] Preferably, a gear ring is provided on the outer side of the drive ring, a gear meshes with the gear ring, the gear is sleeved on the shaft, and the shaft is shaft-connected to the drive motor.

[0011] Preferably, the preheating cylinder is fixedly supported by a support frame, a base plate is fixedly connected inside the support frame, the drive motor is mounted on the base plate, and a bearing seat that is rotatably connected to the end of the shaft is also provided on the base plate.

[0012] Preferably, 2-4 movable frames are provided on each side of the hollow feeding conveyor belt.

[0013] Preferably, the surface of the perforated feeding conveyor belt is provided with multiple perforations.

[0014] According to the above technical solution, the present invention provides a magnesium material preheating and feeding device, which includes a horizontally placed preheating cylinder. A perforated feeding conveyor belt is transversely arranged inside the preheating cylinder. Multiple sets of radially extending movable frames are symmetrically arranged on both sides of the perforated feeding conveyor belt on the preheating cylinder. An electric heating rod is installed at the inner end of the movable frame, and a driving mechanism is connected to the outer end of the movable frame to drive it to move along the radial direction of the preheating cylinder.

[0015] The usage and beneficial effects of this magnesium material preheating and feeding device are as follows: First, the heating rods are energized. Then, the magnesium material is placed on the perforated feeding conveyor belt for transport. When the magnesium material is transported into the preheating cylinder, the heating rods on the upper and lower sides generate heat, effectively preheating the magnesium material. Finally, the preheated magnesium material is conveyed to the processing area via the perforated feeding conveyor belt for feeding. This magnesium material preheating and feeding device can preheat the magnesium material during the feeding and conveying process, avoiding excessive reactions caused by excessively low magnesium material temperatures, which would affect the processing effect. Simultaneously, because the movable frame can be adjusted radially, the heating rods can operate at different positions in the radial direction to obtain different preheating temperatures. The radial position of the heating rods can be adjusted according to the required preheating temperature.

Detailed Implementation

[0024] 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.

[0025] 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.

[0026] See Figure 1-4 The magnesium material preheating and feeding device shown includes a horizontally placed preheating cylinder 1. A perforated feeding conveyor belt 11 is transversely arranged inside the preheating cylinder 1. Multiple sets of radially extending movable frames are symmetrically arranged on both sides of the perforated feeding conveyor belt 11 on the preheating cylinder 1. An electric heating rod 12 is installed at the inner end of the movable frame, and a driving mechanism is connected to the outer end of the movable frame to drive it to move along the radial direction of the preheating cylinder 1.

[0027] By implementing the above technical solution, when using this magnesium material preheating and feeding device, the heating rod 12 is first energized, and then the magnesium material is placed on the perforated feeding conveyor belt 11 for conveying. When the magnesium material is conveyed into the preheating cylinder 1, the heating rods 12 on the upper and lower sides heat up, effectively preheating the magnesium material. Finally, the preheated magnesium material is sent to the processing area via the perforated feeding conveyor belt 11 for feeding. This magnesium material preheating and feeding device can preheat the magnesium material during the feeding and conveying process, avoiding excessive reactions caused by the magnesium material being too cold, which would affect the processing effect. At the same time, since the movable frame can be adjusted in the radial direction, the heating rod 12 can act at different positions in the radial direction to obtain different preheating temperatures. The radial position of the heating rod 12 can be adjusted according to the preheating temperature requirements.

[0028] In this embodiment, the movable frame includes a long wedge-shaped block 14 disposed at its outer end. Multiple rods 13, which slide through the preheating cylinder 1, are fixed to the inner side of the long wedge-shaped block 14. The inner end of each rod 13 has a through hole for inserting the heating rod 12. A spring 16 is sleeved on the rod 13 between the long wedge-shaped block 14 and the preheating cylinder 1. This arrangement facilitates the installation of the heating rod 12, and the spring 16 allows the long wedge-shaped block 14 to quickly return to its original position.

[0029] In this embodiment, the driving mechanism includes a driving ring coaxially arranged with the preheating cylinder 1. L-shaped support frames 53 are provided at both ends of the driving ring. A rotating ring 4, which rotates on the outer wall of the preheating cylinder 1, is fixed to the end of each L-shaped support frame 53. An annular groove corresponding to the rotating ring 4 is provided on the outer wall of the preheating cylinder 1. Multiple driving wedge blocks 15, each corresponding to a long wedge block 14, are provided on the inner side of the driving ring. The wedge-shaped surfaces of the long wedge blocks 14 and the driving wedge blocks 15 are in contact with each other. During operation, the driving ring rotates at a certain angle, causing the wedge-shaped surfaces of the driving wedge blocks 15 to press against each other, providing radial pressure to the long wedge blocks 14. This causes the long wedge blocks 14 to move and adjust the position of the heating rod 12 radially under the guidance of multiple rods 13.

[0030] In this embodiment, a gear ring 2 is provided on the outer side of the drive ring, and a gear 8 meshes with the gear ring 2. The gear 8 is sleeved on the shaft 9, and the shaft 9 is axially connected to the drive motor 7. The drive motor 7 drives the shaft 9 to rotate, which in turn drives the gear 8 to rotate, and then drives the gear ring 2 and the drive ring to rotate. The drive motor 7 is a servo motor, which reciprocates within a preset angle range to ensure that the drive wedge block 15 does not disengage from its corresponding elongated wedge block 14 during rotation.

[0031] In this embodiment, in order to increase the overall operational stability, the preheating cylinder 1 is fixedly supported by a support frame 5, a base plate 6 is fixedly connected inside the support frame 5, the drive motor 7 is mounted on the base plate 6, and a bearing seat 10 that is rotatably connected to the end of the shaft 9 is also provided on the base plate 6.

[0032] In this embodiment, 2-4 movable frames are provided on each side of the perforated feeding conveyor belt 11. The surface of the perforated feeding conveyor belt 11 is provided with multiple perforations.

[0033] The magnesium material preheating and feeding device can drive multiple circumferential movable frames to move synchronously through a drive motor 7, which has good coordination.

[0034] Of course, if the length of the preheating cylinder 1 is increased as needed, multiple sets of the movable frame can be set in the axial direction of the preheating cylinder 1. The multiple sets of movable frames arranged in the circumferential direction can be driven independently by a drive motor 7 to realize the segmented adjustment structure of multiple drive motors 7.

[0035] 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.

[0036] 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.

[0037] 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.
