Description

Technical Field

[0001] This utility model relates to the field of fabric system technology, and in particular to a fabric system. Background Technology

[0002] As a key piece of equipment in ferroalloy smelting, the electric arc furnace (EAF) consists of multiple systems working together, including a feeding system, a fume hood, a furnace body, electrode columns, and a secondary busbar. The feeding system mainly comprises silos and feed pipes. The silos bear the important responsibility of storing smelting raw materials. These raw materials enter the furnace body intermittently or continuously through the feed pipes to participate in smelting. Since smelting continuously consumes raw materials, the silos need to be constantly replenished. In addition, EAFs are usually equipped with multiple silos. Therefore, an efficient material distribution system is indispensable. It can accurately deliver materials to each silo in the feeding system, ensuring the smooth operation of smelting production.

[0003] Chinese patent number CN222211263U discloses a hopper circulation unloading mechanism for a material distribution system. The hopper drives the guide plate to rotate in a circular manner above the electric arc furnace, thereby unloading the material in the hopper into different material pipes through the guide plate, which facilitates the replenishment of material to different silos of the electric arc furnace.

[0004] Material inside the hopper is prone to scaling and clogging of the feed pipe. Although it is easy to think of setting up a stirring structure inside the hopper, the stirring structure needs to be cleaned after long-term use. Since the stirring structure is set inside the hopper, cleaning is very inconvenient, and residual material is also easy to adhere to the inner wall of the equipment, which is also difficult to clean. Utility Model Content

[0005] In view of the shortcomings of the prior art, this utility model provides a material feeding system that can prevent material from scaling in the hopper and facilitate the cleaning of the scraper.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a material distribution system, including a feeding belt and a material distribution mechanism disposed on one side of an electric arc furnace, wherein the material distribution mechanism is connected to the electric arc furnace through a material drop pipe;

[0007] The material feeding mechanism includes a hopper and a scraper. The bottom inner side of the hopper is provided with multiple material discharge holes in a ring shape. The upper end of the material discharge pipe is connected to the material discharge holes. The scraper is rotatably disposed inside the hopper. Multiple material discharge grooves are provided on the circumference of the scraper. The raw material in the hopper enters the material discharge holes through the material discharge grooves.

[0008] The scraper is connected to a rotating mechanism that drives it to rotate, and the rotating mechanism is also connected to a lifting mechanism that drives it to rise and fall.

[0009] Preferably, the rotating mechanism includes a rotary motor, which is installed between the electric arc furnace and the hopper. A rotating shaft is fixedly connected to the outside of the main shaft of the rotary motor, and a sleeve is slidably connected to the outside of the rotating shaft. The sleeve passes through the hopper and is connected to a scraper. An anti-rotation structure is provided between the rotating shaft and the sleeve, and a lifting mechanism is connected to the sleeve.

[0010] Preferably, the anti-rotation structure includes a plurality of strip-shaped protrusions on the surface of the rotating shaft, and the inner side of the sleeve is provided with a strip-shaped through groove that engages with the strip-shaped protrusions.

[0011] Preferably, the lifting mechanism includes a lifting motor and a gear. The lifting motor is disposed between the rotary motor and the hopper, the gear is connected to the main shaft of the lifting motor, and the outer side of the sleeve is provided with several annular teeth that mesh with the gear.

[0012] Preferably, the scraper is conical, and the height of the scraper gradually decreases from the center to the edge.

[0013] Preferably, a plurality of rotating arms are fixedly connected to the upper side of the scraper, and a scraper rod is fixedly connected to the outer side of the end of the rotating arm, with the outer side of the scraper rod contacting the inner side of the hopper.

[0014] Preferably, the lower end of the scraper is disposed in the material discharge chute.

[0015] Preferably, the upper surface of the hopper is provided with a cover plate, which is rotatably connected to the hopper.

[0016] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0017] This utility model utilizes a rotating mechanism to drive the scraper to rotate. During the process of conveying materials to the electric arc furnace, the scraper agitates the materials, promotes uniform mixing, avoids material accumulation and clumping, and ensures smooth conveying and material quality. The rotating mechanism is connected to a lifting mechanism that drives the scraper to rise, which can drive the entire scraper to rise, thereby facilitating the cleaning of the scraper and preventing the material from forming scale on the scraper.

[0018] The scraper intermittently covers the upper side of the discharge hole, and the material falls into the discharge pipe intermittently. The impact of the material falling can effectively reduce the occurrence of blockage in the discharge pipe.

[0019] Compared to the traditional method of feeding materials one by one from a single hopper, this method enables simultaneous feeding of multiple submerged arc furnaces, improving feeding efficiency. It is especially suitable for large-scale, multi-batch production scenarios, enhancing the continuity and stability of the production line. When the scraper rotates, it drives the scraper on one side of the rotating arm to scrape the inner wall of the hopper, promptly removing materials adhering to the inner wall of the hopper and preventing blockages caused by material residue.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1 This utility model provides a technical solution: a material distribution system, including an electric arc furnace 1, a feeding belt 21 and a material distribution mechanism 2 disposed on one side of the electric arc furnace 1, the material distribution mechanism 2 being used to quickly and efficiently replenish the material transported by the feeding belt 21 into the interior of the electric arc furnace 1, the material distribution mechanism 2 including a hopper 22, the hopper 22 being connected to the upper side of the electric arc furnace 1 through a discharge pipe 213.

[0029] The upper side of the hopper 22 is provided with a cover plate 212, which is rotatably connected to the hopper 22 to facilitate cleaning of the inside of the hopper 22.

[0030] See Figures 2-4A scraper 23 is provided on the inner side of the middle part of the hopper 22. Multiple material discharge holes 26 are circumferentially opened on the inner side of the bottom end of the hopper 22. The upper end of the material discharge pipe 213 is connected to the material discharge holes 26. Several material discharge grooves 214 are circumferentially spaced on the circumference of the scraper 23. The material in the hopper 22 enters the material discharge holes 26 after passing through the material discharge grooves 214, and finally enters the electric arc furnace 1 through the material discharge pipe 213. The scraper 23 indirectly covers one side of the material discharge holes 26, and the scraper 23 is connected to a rotating mechanism that drives it to rotate.

[0031] A rotating arm 24 is fixedly connected to the upper surface of the scraper 23. The rotating arm 24 has a cross structure. A vertically arranged scraper 25 is fixedly connected to the outer end of the rotating arm 24. The outer side of the scraper 25 contacts the inner side of the hopper 22. The lower end of the scraper 25 is set in the discharge chute 214.

[0032] The rotating mechanism includes a rotary motor 28, which is installed between the electric arc furnace 1 and the hopper 22. A rotating shaft 29 is fixedly connected to the outside of the main shaft of the rotary motor 28. A sleeve 27 is slidably connected to the outside of the rotating shaft 29. The sleeve 27 passes through the middle of the hopper 22. The top of the sleeve 27 is fixedly connected to the lower surface of the middle part of the scraper 23. An anti-rotation structure is provided between the sleeve 27 and the rotating shaft 29, so that the sleeve 27 can rotate with the rotating shaft 29 and can also rise and fall on the rotating shaft 29.

[0033] The anti-rotation structure in this embodiment includes multiple strip-shaped protrusions on the outside of the rotating shaft 29. A strip-shaped through groove is provided on the inner side of the conveying sleeve 27. The strip-shaped protrusions are inserted into the strip-shaped through groove. By matching the strip-shaped protrusions of the rotating shaft 29 with the grooves opened in the sleeve 27, the sleeve 27 can be driven to rotate.

[0034] The material is conveyed to the inside of the hopper 22 via the feeding belt 21. The rotary motor 28 is started, which drives the rotary shaft 29 to rotate, thereby driving the sleeve 27 and scraper 23 to rotate. At this time, the scraper 23 can push the material to stir, and the material flows through the discharge hole 26 into the interior of the electric arc furnace 1. Moreover, the material enters the discharge pipe 213 intermittently, similar to pulse impact. The impact force of the material falling can be used to avoid the material from clogging in the discharge pipe 213. It can also feed multiple electric arc furnaces 1 at the same time. When the scraper 23 rotates, it can drive the scraper 25 on one side of the rotary arm 24 to scrape the inner wall of the hopper 22, which can scrape the material on the inner wall of the hopper 22 and increase efficiency. The rotary arm 24 can also stir the material inside the hopper 22 separately to promote efficiency.

[0035] like Figure 5 As shown, a lifting motor 210 is installed on the inner side of the top of the electric arc furnace 1. A gear 211 is fixedly connected to the outer side of the main shaft of the lifting motor 210. Several annular teeth that mesh with the gear 211 are provided on the outer side of the sleeve 27.

[0036] During normal feeding, the scraper 23 and sleeve 27 descend to their lowest positions. The lower part of the rotating shaft 29 is equipped with a support plate to support the sleeve 27, and the rotating shaft 29 bears the weight of the hanging plate 23. When it is necessary to lift the scraper 23, first open the cover plate 212, then start the lifting motor 210, which drives the gear 211 to rotate. As the gear 211 rotates, it can drive the sleeve 27 to rise. As the sleeve 27 rises, it will drive the scraper 23 to rise vertically, extending the scraper 23 out from the inside of the hopper 22. This allows for cleaning of the outside of the scraper 23, increasing the practicality of the device.

[0037] Working Principle: The material to be conveyed is placed on the feeding belt 21 and conveyed to the inside of the hopper 22. The rotary motor 28 is started, which drives the rotating shaft 29 to rotate, causing the sleeve 27 and scraper 23 to rotate. The scraper 23 pushes the material to stir, and the material flows into the interior of the electric arc furnace 1 through the discharge hole 26. When the scraper 23 rotates, it can drive the scraper 25 on one side of the rotating arm 24 to scrape the inner wall of the hopper 22, thus removing the material from the inner wall of the hopper 22. During the process of conveying the material to the electric arc furnace 1, the scraper 23 stirs the material, promotes uniform mixing, avoids material accumulation and agglomeration, ensures smooth conveying and material quality, and enables simultaneous feeding of multiple hoppers. Compared with the traditional single-hopper feeding method, it significantly reduces feeding time and improves feeding efficiency, especially suitable for large-scale, multi-batch production scenarios, enhancing the continuity and stability of the production line.

[0038] After running for a period of time, the user can start the lifting motor 210 to drive the gear 211 to rotate. As the gear 211 rotates, it can drive the sleeve 27 and scraper 23 to rise vertically, so that the scraper 23 can be extended from the inside of the hopper 22 to clean the outside of the scraper 23. The outside of the scraper 23 can be cleaned without disassembling the equipment parts, which significantly reduces the difficulty and time cost of maintenance, reduces equipment downtime, and ensures the continuous operation of the production line.

[0039] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
