Description

Technical Field

[0001] This utility model relates to the field of metal smelting equipment technology, and in particular to a feeding device for vacuum electric furnace processing. Background Technology

[0002] In the field of metal smelting and processing, vacuum electric furnaces are widely used in the production of high-quality materials such as special steels and high-temperature alloys because they can effectively reduce impurity contamination during the smelting process and precisely control alloy composition. Among them, the feeding device, as a key piece of equipment connecting the storage of raw materials such as scrap steel to the smelting chamber of the vacuum electric furnace, directly affects the continuity of the entire production process and the utilization rate of raw materials due to its operating efficiency and stability. It is an important link in ensuring the efficient production of vacuum electric furnaces.

[0003] Existing feeding equipment for vacuum electric furnace processing mostly adopts a track-type translation structure combined with a fixed boom design. The technical principle is mainly to adjust the lateral position of the boom by the horizontal movement of the track slider, and the boom's pitch angle is locked at a fixed position by bolts. Material grabbing relies on manual hooking, and then the motor is started to drive the steel cable to achieve vertical lifting. Throughout the process, it is difficult to dynamically adjust the boom's working radius and angle according to real-time needs.

[0004] However, in the existing technology, the material handling requires manual assistance for alignment, and operators need to frequently travel back and forth between the raw material stacking area and the electric furnace feed port. This not only increases the amount of manpower required, but also makes it difficult to accurately match the feeding rhythm with the melting requirements of the vacuum electric furnace due to the intermittency and reaction delay of manual operation, which seriously restricts the improvement of production efficiency. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a feeding device for vacuum electric furnace processing, which aims to improve the low production efficiency caused by the need for manual material handling in traditional equipment.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a feeding device for vacuum electric furnace processing, comprising a base rod, a connecting plate fixedly connected to the upper surface of the base rod, an automatic feeding component disposed above the connecting plate, and an adjustment component disposed above the base rod; The automatic feeding assembly includes an electromagnet, the outer wall of which is disposed above a connecting plate.

A wire feeding reel is rotatably connected to the inner wall of the clamping plate. A steel wire rope is wound around the outer wall of the wire feeding reel. A hook is fixedly connected to one end of the steel wire rope.

[0008] Furthermore, a bracket is fixedly connected to the upper surface of the base rod, a counterweight is fixedly connected to the upper surface of the base rod, a support rod is fixedly connected to the upper surface of the base rod, a hopper is fixedly connected to the upper surface of the support rod, a sliding groove is opened inside the hopper, a vibration motor is fixedly connected to the outer wall of the hopper, a feeding trough is fixedly connected to the lower surface of the hopper, and a pressure rod is fixedly connected to the upper surface of the base rod.

[0009] Furthermore, the outer wall of the baffle is slidably connected to the inner wall of the groove.

[0010] Furthermore, the outer wall of the rotating cover is rotatably connected to the inner wall of the outer shell, and the outer wall of the rotating motor is fixedly connected to the upper surface of the connecting plate.

[0013] Furthermore, the inner wall of the slide rail is fixedly connected to the outer wall of the hopper.

[0014] This utility model has the following beneficial effects: In this invention, by turning on the rotary motor to drive the rotating cover to rotate, adjusting the angle of the support base and its upper structure to a suitable position, opening the hydraulic telescopic rod to raise the upper arm, and extending the lower arm, so that the wire feeding reel is directly above the scrap steel, rotating the wire feeding reel to lower the wire rope, causing the hook and electromagnet to descend synchronously. After the electromagnet attracts the scrap steel, the rotating cover is adjusted so that the electromagnet is directly above the hopper, and the scrap steel is fed into the hopper. This solves the problem of low production efficiency caused by the need for manual material handling in traditional equipment, and achieves the effect of reducing labor costs and increasing the feeding speed.

[0015] In this invention, a cylinder pushes a slider, causing the slider to slide downwards on the outer wall of the slide rail. This drives the connecting rod to rotate, causing the round rod to move outwards, which in turn causes the baffle to slide outwards, adjusting the area of ​​the feeding port and thus the feeding speed. This adapts to different material characteristics and avoids material jamming in the furnace due to excessive feeding speed. Attached Figure Description

[0020] Specifically, the rotary motor 12 drives the rotating cover 11 to rotate, which in turn drives the support base 13 and the upper structure to rotate. When the hydraulic telescopic rod 15 extends or retracts, it rotates in the clamping plate 14 and clamping plate 26, which drives the boom 17 to rotate and thus adjust the working angle. The forearm 18 slides on the inner wall of the boom 17 to adjust the working radius. The wire feeding reel 20 adjusts the height of the hook 22 and the electromagnet 23 by rotating the wire rope 21, so that after the electromagnet 23 has absorbed the scrap steel, it is fed into the hopper 8.

A connecting rod 27 is rotatably connected to the outer wall of the round rod 28, which connects the connecting rod 27 and the baffle 29. A slider 25 is rotatably connected to the inner wall of the connecting rod 27, which slides on a slide rail 24, causing the connecting rod 27 to rotate. The slide rail 24 is slidably connected to the inner wall of the slider 25. The slide rail 24 provides guidance and limit for the sliding of the slider 25. A cylinder 26 is fixedly connected to the outer wall of the slide rail 24. The output end of the cylinder 26 is fixedly connected to the upper surface of the slider 25. The cylinder 26 is used to provide power for the sliding of the slider 25. A bracket 2 is fixedly connected to the upper surface of the base rod 1. The bracket 2 is used to enhance the connection stability between the base rod 1 and the support rod 3. A counterweight 7 is fixedly connected to the upper surface of the base rod 1. The counterweight 7 is used to balance the center of gravity of the device and prevent the device from shaking due to uneven load during operation. A support rod 3 is fixedly connected to the hopper 8, providing a support base for the hopper 8. The hopper 8 is fixedly connected to the upper surface of the support rod 3. The hopper 8 is used to temporarily store materials to be processed. A sliding groove 30 is opened inside the hopper 8. A vibration motor 4 is fixedly connected to the outer wall of the hopper 8. When the vibration motor 4 is working, it generates vibration, which can loosen the material in the hopper 8 and ensure smooth feeding. A feeding chute 9 is fixedly connected to the lower surface of the hopper 8. The feeding chute 9 can guide the material in the hopper 8 to the designated feeding position. The upper surface of the base rod 1 is fixedly connected to... A pressure rod 5 is connected to the base rod 1 to enhance its stability. The outer wall of the baffle 29 is slidably connected to the inner wall of the slide groove 30. The outer wall of the rotating cover 11 is rotatably connected to the inner wall of the outer shell 10.

The inner wall of the slide rail 24 is fixedly connected to the outer wall of the hopper 8.

[0022] Specifically, the extension and retraction of the output end of the cylinder 26 provides power for the sliding of the slider 25, causing the connecting rod 27 to rotate, which drives the round rod 28 to move outward in the horizontal direction, thereby driving the baffle 29 to move outward in the slide groove 30, thereby changing the blocking area of ​​the baffle 29 and adjusting the feeding speed.

[0023] Working principle: When a vacuum electric furnace feeding device is needed, the operator opens the hydraulic telescopic rod 15 to extend it. The hydraulic telescopic rod 15 rotates on the inner wall of clamping plate 14 and clamping plate 2 16, thereby raising the upper arm 17 and extending the lower arm 18 to increase the working radius. The rotary motor 12 is turned on, driving the rotating cover 11 to rotate, so that the support base 13 rotates with it. The upper arm 17 and the lower arm 18 rotate synchronously. After rotating above the scrap steel, the wire rope 21 is lowered by rotating the wire reel 20. The electromagnet 23 is activated to approach the scrap steel and attract it. Then, the rotating cover 11 is rotated by the rotary motor 12 to adjust the upper arm 17 and the lower arm 18 to be directly above the hopper 8. The electromagnet 23 is de-energized, so that the scrap steel is sent into the hopper 8. In addition, when it is necessary to adjust the feeding speed, the cylinder 26 is turned on, and its output end drives the slider 25 to slide on the slide rail 24. When the slider 25 slides down, it presses down the connecting rod 27, causing the connecting rod 27 to rotate, which drives the round rod 28 to move outward, so that the baffle 29 slides outward in the slide groove 30, adjusting the feeding area between the hopper 8 and the feeding groove 9, thereby realizing the adjustment of the feeding speed.
