[0037] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0038] This utility model provides an overall structural schematic diagram of an embodiment of a submerged arc furnace feeding device, including:

[0039] Please see Figures 1-5 The electric arc furnace feeding device of this embodiment includes an outer shell assembly 100, a storage assembly 200 disposed inside the outer shell assembly 100, a weighing assembly 300 disposed at the bottom of the storage assembly 200, and a discharge assembly 400 disposed at the bottom of the weighing assembly 300.

[0040] The housing assembly 100 includes a housing 110, with a feeding port 120 tightly welded to the top of the housing 110, and a plurality of standing legs 130 fixedly connected to the bottom of the housing 110.

[0041] The storage assembly 200 includes an outer frame 210 disposed inside the housing 110, a guide block 220 tightly welded to the inner cavity of the outer frame 210, a pull-out bottom plate 240 tightly welded to the bottom of the outer frame 210, and a pull-out plate 230 slidably connected inside the pull-out bottom plate 240.

[0042] The weighing assembly 300 includes a weighing box 310 disposed at the bottom of the storage assembly 200. A guide block 320 is tightly welded to the inner cavity of the weighing box 310. Multiple feeding plates 340 are disposed at the bottom of the weighing box 310. Slide rails 330 are slidably connected to both sides of the feeding plates 340. A push-pull motor 350 is disposed on the side of the feeding plates 340. A weighing device 360 ​​is disposed at the bottom of the slide rails 330. A base shell 370 is fixedly connected to the bottom of the weighing device 360.

[0043] The discharge assembly 400 includes a discharge frame 410 disposed at the bottom of the weighing assembly 300. A first snap-fit ​​block 420 is fixedly connected to the top of the discharge frame 410, a second snap-fit ​​block 430 is fixedly connected to the outlet of the discharge frame 410, a third snap-fit ​​block 440 is fixedly connected to the bottom of the discharge frame 410, a sound-absorbing plate 450 is snap-fitted to the side of the second snap-fit ​​block 430, a base 460 is snap-fitted to the bottom of the third snap-fit ​​block 440, and a push-pull plate 470 is fixedly connected to the side of the base 460.

[0044] It is worth noting that, in order to make the pull-out plate 230 less susceptible to the influence of the ore, specifically, the top of the pull-out plate 230 is fixedly connected with a retaining strip, and the side of the pull-out plate 230 is fixedly connected with a triangular prism. The dimensions of the retaining strip and the triangular prism are matched with those of the pull-out plate 230.

[0045] Next, in order to prevent the material plate 340 from bending under load, a push-pull rod is specifically fitted on the side of the push-pull motor 350. The push-pull rod is fixedly connected to the material plate 340. Protruding blocks are fixedly connected to both sides of the material plate 340, and the size of the protruding blocks matches the slide rail 330.

[0046] Meanwhile, in order to make the discharge port 380 fit into the discharge frame 410, the bottom of the base shell 370 is fixedly connected to the discharge port 380, and the bottom of the discharge port 380 is provided with a beveled groove, which matches the size of the discharge frame 410.

[0047] In this process, when the ore is poured into the outer frame 210 of the storage component 200 through the feeding port 120, it is stored there. When it needs to be discharged, the ore is pulled out by the pull-out plate 230 on the side of the bottom pull-out plate 240 of the outer frame 210 to allow it to enter the weighing component 300. When it needs to be stopped, the pull-out plate 230 is pushed, and the triangular prism on the side of the plate 240 squeezes the ore to prevent it from getting stuck and closing. The design of the pull-out plate 230 increases the feeding efficiency and prevents the ore from getting stuck and unable to be discharged. When the ore enters the weighing component 300, it is first weighed by the weighing box 31. The guide block 320 inside the weighing box 310 guides the material to the center of the weighing box 310. Then, the material discharge gate, which is composed of the bottom slide rail 330, the material discharge plate 340, and the push-pull motor 350 of the weighing box 310, is ready. When the weighing device 360 ​​at the bottom of the material discharge plate 340 detects the appropriate amount, it will be displayed by the controller on the side of the outer casing 110. When the weighing is completed, the push-pull motor 350 will drive the material discharge plate 340 to slide on the material discharge plate 340 to discharge the material. The material discharge port 380 at the bottom of the base casing 370 is to prevent the ore from splashing out due to impact during the discharge.

[0048] Furthermore, in order to facilitate the attachment of the discharge frame 410 to the outer casing 110, a slot is provided on the top of the snap-fit ​​block 420, and a snap-fit ​​block is fixedly connected to the inner wall of the outer casing 110, with the slot matching the size of the snap-fit ​​block.

[0049] It is worth noting that, in order to disassemble the discharge assembly 400, a handle is fixedly connected to the side of the push-pull plate 470, the size of the opening on the side of the push-pull plate 470 matches the size of the opening on the side of the housing 110, and the top of the base 460 is provided with a groove that matches the snap-fit ​​block 440.

[0050] When the discharge assembly 400 needs to be replaced, pull out the handle on the push-pull plate 470 to remove the base 460 and the upper discharge frame 410 from the outer casing 110. At the same time, the first snap-fit ​​block 420 on the top of the discharge frame 410 will separate from the snap-fit ​​block 420 inside the outer casing 110. Then, the discharge frame 410 can be lifted to separate the third snap-fit ​​block 440 at the bottom of the discharge frame 410 from the base 460. Then, pull out the silencing plate 450 that is snapped against the second snap-fit ​​block 430 on the side of the discharge frame 410 for easy replacement. The silencing plate 450 not only ensures that the ore does not wear or corrode the discharge assembly 400 excessively, but also avoids the noise generated by the direct impact of the ore on the discharge frame 410 when it falls, thereby extending the service life of the discharge frame 410.

[0051] Finally, for better specific results, the sound-absorbing plate 450 includes a rubber plate, and multiple rounded corner blocks are fixedly connected to the top of the rubber plate. The size of the rounded corner blocks matches the size of the rubber plate.

[0052] In some embodiments, the sound-absorbing plate 450 is made of general-purpose rubber. General-purpose rubber refers to rubber types that partially or completely replace natural rubber, such as styrene-butadiene rubber, butadiene rubber, and isoprene rubber, mainly used in the manufacture of tires and general industrial rubber products. General-purpose rubber is in high demand and is a major type of synthetic rubber.

[0053] In addition, the circuits, electronic components and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the internal structure and method.

[0054] The device or equipment models mentioned in this article may be as follows:

[0055] Push-pull motor 350: 25GA370.

[0056] Combination Figures 1-5 The specific usage process of the electric arc furnace feeding device of this embodiment is as follows:

[0057] 1. When the submerged arc furnace feeding device starts working, the material is first added to the storage assembly 200 inside the outer shell 110 through the feeding port 120 at the top of the outer shell assembly 100. The storage assembly 200 consists of an outer frame 210 and an internal guide block 220, ensuring that the material can be smoothly guided and stored in the device. The design of the pull-out bottom plate 240 and the pull-out plate 230 fitted inside it allows the operator to adjust the material storage amount as needed.

[0058] 2. When ore needs to be fed, the weighing component 300 located at the bottom of the storage component 200 starts working. The weighing device 360 ​​accurately measures the weight of the ore falling from the storage component 200, ensuring accuracy with each feeding. Guide blocks 320 inside the weighing box 310 ensure the ore is concentrated within the weighing box 310 for detection by the weighing device 360. Once weighing is complete, the discharge plate 340, driven by the push-pull motor 350, moves along the slide rail 330 to release the material. The ore then falls through the opening at the bottom of the weighing box 310 into the discharge component 400 below. The design of the discharge plate 340 allows for quick and precise control of the material release, ensuring the stability and controllability of the feeding process. Data from the weighing device 360 ​​can be fed back in real time, helping the operator monitor and adjust the feeding amount. Simultaneously, the discharge port 380 at the bottom of the base housing 370 and its beveled groove design facilitate smooth material entry into the discharge frame 410, reducing blockages and waste.

[0059] 3. After the material enters the discharge frame 410 of the discharge assembly 400, it is securely connected to the inner wall of the outer casing 110 via the first snap-fit ​​block 420, ensuring the stability of the discharge process. The discharge frame 410 has a second snap-fit ​​block 430 at its outlet, and its side sound-absorbing plate 450 consists of a rubber plate and rounded corner blocks, effectively reducing noise and vibration during material descent. After the material is completely discharged, the operator can use the handle on the push-pull plate 470 to pull the discharge frame 410, along with the base 460, out of the outer casing 110 for cleaning or maintenance. The groove design on the top of the base 460 facilitates the quick installation and removal of the third snap-fit ​​block 440. After the entire feeding process is completed, all components reset, ready for the next operation, ensuring the continuous and efficient operation of the submerged arc furnace feeding device.

[0060] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
