Technical Field

[0001] This utility model belongs to the field of metal smelting technology, and specifically relates to a safety device for preventing splashing injuries during metal smelting. Background Technology

[0002] In the metal smelting process, workers need to add materials to the smelting furnace. During the falling process, the high-temperature materials will splash out of the smelting furnace, causing injury to the workers. Patent application number "CN202321443761.5" discloses a smelting device for recycling and smelting waste cast iron from cast iron parts, including a smelting furnace. The upper end of the smelting furnace is movably equipped with a protective cover. The upper end of the protective cover is fixedly installed with a fixing ring. The inner side of the fixing ring is movably equipped with a cover plate. The protective cover is movably equipped with a toggle assembly, which includes a rotating ring, a toothed ring, a gear, a rotating handle, a sleeve handle, and a toggle plate. The outer surface of the protective cover is fixedly installed with a reinforcing column. The lower surface of the protective cover is fixedly installed with multiple self-locking universal wheels at equal intervals. In this invention, when waste cast iron filings are poured into the smelting furnace, a protective structure is used to cover the top of the smelting furnace to prevent the high-temperature iron filings inside the smelting furnace from splashing outwards and causing injury to personnel. Furthermore, after the waste cast iron filings are manually placed inside the smelting furnace, the waste cast iron filings that have not entered the smelting furnace can be indirectly moved into the smelting furnace by manual intervention, thereby reducing the safety hazards when adding waste cast iron filings.

[0003] The aforementioned patent uses a rotating lever to clean the material attached to the protective cover, avoiding the situation where high-temperature material splashes when workers manually clean the material attached to the protective cover. However, the aforementioned device is in a closed state during the process of adding material into the smelting furnace. The high-temperature raw materials inside the smelting furnace are prone to splashing to the outside during the falling process. Moreover, the aforementioned patent lacks a sealing component for the gap between the protective cover and the smelting furnace, and the high-temperature raw materials can easily splash to the outside from the gap between the protective cover and the smelting furnace.

[0023] Please see Figure 1-8 This utility model provides the following technical solution: a metal smelting splash prevention safety device, including a smelting furnace 1, a protective cover 2 and a spring telescopic rod 6, and also includes an adjustment mechanism 3, a rotating cylinder 4 and a scraper 5. The side wall of the smelting furnace 1 is provided with an installation ring 11, the protective cover 2 is installed on the installation ring 11, the rotating cylinder 4 is rotatably installed on the protective cover 2, the side wall of the groove on which the rotating cylinder 4 is installed on the protective cover 2 and the rotating cylinder 4 are provided with a corresponding through groove 42, the side wall of the rotating cylinder 4 is provided with a bevel tooth ring 33, the protective cover 2 is rotatably installed with a bevel gear rod 31 that meshes with the bevel tooth ring 33, the top surface protrusion of the rotating cylinder 4 passes through the side wall of the groove on which the rotating cylinder 4 is installed and a scraper 5 is installed thereon, multiple impact blocks 51 are installed on the side wall of the protective cover 2 through which the rotating cylinder 4 passes, via the spring telescopic rod 6, and the scraper 5 is provided with an impact groove 52 that cooperates with the impact blocks 51.

[0024] Smelting furnace 1 is used for smelting. It is a common and mature piece of equipment and does not require detailed description in the instruction manual. Mounting ring 11 is used to mount protective cover 2, which protects the workers. After protective cover 2 is installed on mounting ring 11, there will be no gaps between smelting furnace 1 and protective cover 2.The top of the protective cover 2 is hinged with a sealing plate, which seals the top opening of the protective cover 2. The cooperation between the mounting ring 11 and the top sealing plate of the protective cover 2 ensures the airtightness of the protective cover 2 after it is installed on the smelting furnace 1. The protective cover 2 is used for temporary storage of materials. The through groove 42 provided on the rotating cylinder 4 is used for the materials stored in the protective cover 2 to enter the interior of the smelting furnace 1. When the user adds materials to the interior of the protective cover 2, the rotating cylinder 4 is rotated, so that the rotating cylinder 4 and the through groove 42 provided on the groove on which the rotating cylinder 4 is installed are misaligned. At this time, the bottom of the protective cover 2 is sealed, and the materials will not directly enter the smelting furnace 1. After the materials are stored in the protective cover 2, the rotating cylinder 4 is controlled to rotate, and the through groove provided on the groove on which the rotating cylinder 4 is installed... When the 42 connection is established, the material stored in the protective cover 2 falls into the smelting furnace 1. This method of adding material can prevent it from splashing to the outside during the adding process. The adjustment mechanism 3 is used to control the rotation of the rotating cylinder 4. The bevel gear rod 31 and the bevel gear ring 33 mesh. When the user rotates the bevel gear rod 31, the bevel gear ring 33 is rotated by the bevel gear rod 31. The rotating bevel gear ring 33 drives the rotating cylinder 4 to rotate. The scraper 5 is used to stir the material stored in the protective cover 2. During the rotation of the rotating cylinder 4, the rotating cylinder 4 drives the scraper 5 to rotate. The rotating scraper 5 will push the material stored inside the protective cover 2 into the through groove 42, which facilitates the device to add material into the smelting furnace 1. The rotating scraper 5 also scrapes off the material adhering to the inner wall of the protective cover 2. During the material addition process, the rotating cylinder 4 causes the through groove 42 on the groove where the rotating cylinder 4 is installed to switch back and forth between connected and staggered states, realizing the addition of material in small amounts multiple times, which makes it easy for the user to control the addition of material. The shape of the scraper 5 matches the shape of the protective cover 2, ensuring the working effect of the scraper 5. The top protrusion of the rotating cylinder 4 and the side wall of the groove where the scraper 5 is installed on the top protrusion of the rotating cylinder 4 are provided with matching protrusions and grooves, ensuring that the rotating cylinder 4 can smoothly move and rotate with the scraper 5 during the rotation process. The top surface of the rod part of the scraper 5 is a slope that slopes from the center to both sides. The central part of the scraper 5 The top surface of the scraper 5 is conical, ensuring that material does not accumulate on it. During rotation, the scraper 5 pushes against the impact block 51, compressing the spring telescopic rod 6 on the impact block 51. As the scraper 5 continues to rotate, the impact groove 52 moves to a position that engages with the impact block 51. The spring telescopic rod 6 then returns to its original position, and the impact block 51, pushed by the spring telescopic rod 6, moves back to its original position. The moving impact block 51 impacts the side wall of the impact groove 52. With the impact of the impact block 51, the scraper 5 begins to vibrate, shaking off the material adhering to it. The protective cover 2 and the scraper 5 are equipped with a series of matching impact blocks 51 and impact grooves 52, ensuring the effective operation of the impact block 51.

[0025] Specifically, the protective cover 2 has a plug rod 32 on its side wall, and a moving block 34 is installed on the end face protrusion of the shaft of the bevel gear rotating rod 31 through a spring telescopic rod 6. The moving block 34 has a groove that cooperates with the bevel gear ring 33.

[0026] The cooperation between the insert rod 32 and the movable block 34 serves to fix the bevel gear rotating rod 31. The fixed bevel gear rotating rod 31 ensures the stability of the rotating cylinder 4 during use. The movable block 34 is installed in the end face groove of the bevel gear rotating rod 31 via the spring telescopic rod 6. When the user rotates the bevel gear rotating rod 31, pressing the movable block 34 causes it to enter the groove where it is installed. At this time, the insert rod 32 disengages from the movable block 34, releasing the fixation of the bevel gear rotating rod 31. When the bevel gear rotating rod 31 is fixed... The rotating cylinder 4 and the through groove 42 provided on the groove on which the rotating cylinder 4 is installed are offset. When it is necessary to fix the bevel gear rod 31, the moving block 34 is released. The moving block 34 is pushed onto the cross-section of the insert rod 32 under the action of the spring telescopic rod 6. The bevel gear rod 31 continues to rotate. When the moving block 34 rotates to the position where the insert rod 32 is engaged, the moving block 34 is pushed by the spring telescopic rod 6. The insert rod 32 enters the interior of the groove that is engaged with it, thereby realizing the automatic fixing of the bevel gear rod 31 and making it convenient for users to fix the device.

[0027] Specifically, a base plate 41 is mounted on the bottom surface of the rotating cylinder 4 by screws.

[0028] During the process of material entering the smelting furnace 1, splashing may occur. The position of the bottom plate 41 can prevent splashed material from adhering to the rotating drum 4. The removable bottom plate 41 makes it easy for the user to replace the bottom plate 41 and clean the bottom plate 41.

[0029] Specifically, the two through slots 42 provided on the side wall of the rotating cylinder 4 and the slot on which the rotating cylinder 4 is installed are centrally symmetrical.

[0030] By setting two through slots 42, the falling speed of the material is increased. The position and shape of the through slots 42 ensure that the two through slots 42 set on the side wall of the rotating cylinder 4 and the slot on which the rotating cylinder 4 is installed are simultaneously connected or separated.

[0031] Specifically, the scraper 5 is mounted on the side wall of the groove protruding at the top of the rotating cylinder 4, and a soft pad is provided.

[0032] The soft pads act as shock absorbers. When the scraper 5 begins to vibrate under the impact of the impact block 51, the soft pads reduce the vibration transmitted to the rotating cylinder 4, thus reducing the damage to other parts of the device caused by vibration.

[0033] Specifically, the bottom surface of the mounting ring 11 is provided with ribs that are connected to the side wall of the smelting furnace 1.

[0034] The bottom ribs of the mounting ring 11 serve to support the mounting ring 11. The ribs ensure the stability of the connection between the mounting ring 11 and the smelting furnace 1, thereby ensuring the stability of the protective cover 2 and the mounting ring 11 during the use of the device.

[0035] Specifically, the bottom of the protective cover 2 is provided with a detachable movable base 21.

[0036] The bottom of the movable seat 21 is equipped with several casters. The movable seat 21 installed on the protective cover 2 makes it easy for the user to move the protective cover 2. The detachable movable seat 21 ensures that the movable seat 21 will not obstruct the user from installing the protective cover 2 onto the mounting ring 11.

[0037] The working principle and usage process of this utility model are as follows: The protective cover 2 is removed from the movable base 21, and then installed onto the mounting ring 11. Material is added to the interior of the protective cover 2. When adding material to the interior of the smelting furnace 1, the movable block 34 is moved, the insert rod 32 separates from the movable block 34, the fixing of the bevel gear rotating rod 31 is released, and the rotating bevel gear rotating rod 31 is rotated. The rotating cylinder 4 is driven to rotate by the bevel gear rotating rod 31 under the cooperation of the meshing bevel gear rotating rod 31 and the bevel gear ring 33. During the rotation of the rotating cylinder 4, the two through slots 42 provided on the side wall of the groove where the rotating cylinder 4 is installed switch between connected and disconnected states. When the through groove 42 is connected, the material enters the interior of the smelting furnace 1. During the rotation of the rotating cylinder 4, the scraper 5 will rotate. During the rotation of the scraper 5, the raw materials stored inside the protective cover 2 will be agitated. During the rotation of the scraper 5, the impact block 51 will be pushed into the groove where the impact block 51 is installed. The scraper 5 continues to rotate, and the impact block 51 will hit the impact groove 52 under the action of the spring telescopic rod 6. The scraper 5 will start to vibrate, thus cleaning the material attached to the scraper 5. After the material is added, the moving block 34 is released. Under the action of the spring telescopic rod 6, the moving block 34 moves to the position that cooperates with the insert rod 32. The bevel gear rotating rod 31 is fixed by the cooperation of the insert rod 32 and the moving block 34.
