Description

Technical Field

[0001] This utility model relates to the field of briquetting technology, and more specifically, to an automatic feeding device for fused magnesia briquetting. Background Technology

[0002] Briquetting is mainly used for pressing and shaping various powdery materials, that is, pressing the powder coming out of the kiln into briquettes for smelting. In the process of producing fused magnesia, briquetting is required.

[0003] A search revealed that utility model patent CN216032754U discloses an automatic feeding system for fused magnesia briquetting, comprising a load-bearing box, a feeding mechanism, and a briquetting mechanism. The load-bearing box has a discharge port at one end of its top and a discharge channel at one end. A conveying mechanism is fixedly connected to the top of the discharge channel. The conveying mechanism includes a rotating motor, with an assembly wheel fixedly connected to the output end of the rotating motor. A transmission wheel is hinged to the outside of the assembly wheel. A third conveyor belt is fixedly connected to one side of the transmission wheel, and a pressure sensor is fixedly connected to one side of the top of the third conveyor belt. The arrangement of the assembly wheel, transmission wheel, and pressure sensor in this patent enables the approximate measurement of raw materials during automatic feeding and transportation, improving production efficiency and reducing the labor intensity of workers.

[0004] However, the aforementioned patent has the following shortcomings: when discharging material from the outlet below the mixing tank, it is not easy to ensure that the fused magnesia material entering the pressing cylinder is evenly distributed, which easily leads to incomplete briquetting and damage to the briquettes; in addition, the fused magnesia briquettes formed by the pressing cylinder are not easy to fall off the pressing cylinder, affecting subsequent briquetting. To address these issues, we propose an automatic material distribution device for fused magnesia briquetting. Utility Model Content

[0027] For details, please refer to Figure 3 and Figure 4 The molding mechanism 2 includes two pressure cylinders 14 rotatably connected to the inner cavity of the molding box 1 and a first motor 15 fixedly installed on the outside of the molding box 1. One end of the rotating shaft of each of the two pressure cylinders 14 extends to the outside of the molding box 1 and is fixedly sleeved with a first gear 16. The two first gears 16 mesh with each other. The output shaft of the first motor 15 is connected to the other end of the rotating shaft of one of the pressure cylinders 14.

[0028] In this embodiment, the sides of the two pressure cylinders 14 are in contact, and the forming holes on the pressure cylinders 14 are aligned.

[0029] For details, please refer to Figure 3 and Figure 4 The scraping mechanism 3 includes two rotating rods 17 rotatably connected to the inner cavity of the forming box 1. Multiple scrapers 18 are fixedly connected to the outer sides of the two rotating rods 17 respectively. The rotating rods 17 and scrapers 18 are located directly below the pressing cylinder 14. The ends of the two rotating rods 17 extend to the outside of the forming box 1 and are fixedly sleeved with second gears 19. The two second gears 19 mesh with the two first gears 16 respectively.

[0030] In this embodiment, the top of the scraper 18 can contact the bottom surface of the pressure cylinder 14.

[0031] For details, please refer to Figure 1 One end of the fabric box 7 is threaded with a threaded plug 20, and the other end of the fabric box 7 is provided with a vent hole 21.

[0032] In this embodiment, fused magnesium oxide is added to the fabric box 7 by removing the threaded plug 20, and the vent hole 21 is used to prevent negative pressure from being generated in the upper part of the inner cavity of the fabric box 7, which would affect the movement of the piston plate 9.

[0033] For details, please refer to Figure 2 The side of the piston plate 9 fits against the inner wall of the fabric box 7.

[0034] In this embodiment, the piston plate 9 is ensured to fully push the fused magnesia in the inner cavity of the cloth box 7.

[0035] For details, please refer to Figure 2 and Figure 3 The side of the fabric box 7 fits against the inner wall of the movable groove 4.

[0036] In this embodiment, the inner wall of the movable groove 4 is used to limit the fabric box 7 to prevent the fabric box 7 from swaying laterally.

[0037] Working principle: In use, first remove the threaded plug 20 and place the fused magnesia material into the feeding box 7. At the same time, start the first motor 15 to drive one pressure cylinder 14 and one first gear 16 to rotate. The meshing transmission between the two first gears 16 drives the two pressure cylinders 14 to rotate in opposite directions. In addition, the meshing transmission between the second gear 19 and the first gear 16 drives the rotating rod 17 and the scraper 18 to rotate. Then, start the electric push rod 8 to drive the piston plate 9 to move down. The piston plate 9 uses the piston plate 9 to push the fused magnesia in the feeding box 7 from the feeding trough 13. The material falls between the two pressing cylinders 14, and at the same time, the second motor 11 is started to drive the cam 12 to rotate. The cam 12 pushes the push plate 6 and the material box 7 to move upward, and the restoring force of the spring 5 drives the push plate 6 and the material box 7 to move downward and reset. The material box 7 vibrates up and down, causing the material in the material box 7 to fall from the material trough 13. Finally, the fused magnesia falling onto the pressing cylinder 14 is pressed into shape. In addition, the scraper 18 scrapes the bottom of the pressing cylinder 14, so that the fused magnesia formed on the pressing cylinder 14 falls smoothly.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
