Description

Technical Field

[0001] This invention relates to the field of lost-mold casting technology, and more particularly to an automatic slag removal device for casting and melting. Background Technology

[0002] The lost-mold casting process requires the melting of metal materials. Melting is a systematic process with the core objective of obtaining high-performance cast iron with spheroidal graphite distribution. The main steps include: raw material preparation, molten iron melting, spheroidization treatment, inoculation treatment, and subsequent quality control. During molten iron melting, slag is generated due to the reaction of elements such as silicon, manganese, and iron in the molten iron with oxygen in the air at high temperatures, resulting in oxides (e.g., Fe2O3, SiO2) on the surface of the furnace charge (pig iron, scrap steel), adhered sand, rust, non-metallic inclusions in alloy additives (e.g., ferrosilicon, ferromanganese), and oxides such as SiO2, MnO, and FeO. This slag is mostly in a glassy or solid state and accumulates on the surface of the molten iron. If not removed in time, it can be incorporated into the casting, forming inclusion defects. Furthermore, the slag can block the pouring channels, preventing the casting from filling the mold. Therefore, after the molten iron is melted, a slag remover is mainly sprinkled on the surface of the molten iron. The slag remover can make the slag in the furnace stick together. The smelting personnel use iron forks to pick out the slag, remove the slag from the molten iron, and finally purify the molten iron.

[0003] The molten slag inside the furnace is highly viscous and heavy, making it very difficult to remove. Manual slag removal involves constantly scorching workers at extremely high temperatures, and there's also the risk of slipping and falling into the furnace. Therefore, an automatic slag removal device is needed to improve efficiency. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide an automatic slag removal device for casting and smelting, which solves the problems in the background art.

[0005] To achieve the above objectives, the present invention provides an automatic slag removal device for casting and smelting, comprising a sliding base, a sliding rail for forward and backward sliding at the bottom of the sliding base, a push motor at one end of the top of the sliding base, a slider for left and right sliding fixedly connected to the output end of the push motor, a connecting arm fixedly connected to the top end of the slider, a lifting cylinder at the bottom of the other end of the connecting arm, a mounting plate fixedly connected to the bottom output end of the lifting cylinder, a collection box with a side opening connected to the bottom of the mounting plate, the bottom of the collection box being a perforated plate, and a collection mechanism provided at the side opening of the collection box, the collection mechanism collecting smelting slag into the collection box.

[0006] Preferably, the collection mechanism includes a horizontal push cylinder disposed on the top of the mounting plate near the opening end, a connecting plate connected to the side output end of the horizontal push cylinder, a horizontal push vertical plate disposed at the bottom of the connecting plate, the horizontal push vertical plate being located at the opening of the collection box, and a collection inclined plate disposed at the bottom end of the horizontal push vertical plate near the opening. The horizontal push vertical plate and the collection inclined plate push the smelting slag through the opening onto the bottom mesh plate inside the collection box, and the horizontal push vertical plate can block the opening.

[0007] Preferably, the horizontal pusher plate has flared guide plates on both sides of the end near the opening, and the bottom of the guide plates is located at the top of the collecting inclined plate.

[0008] Preferably, the bottom mesh plate of the collection box is inclined downwards towards the end away from the opening, and the inclination of the mesh plate is the same as the inclination of the collection inclined plate.

[0009] Preferably, the end of the collection box away from the opening is a door, the top of the door is rotatably connected to the top of the collection box by a hinge, and the bottom of the door is fixed to the bottom of the collection box by a latch.

[0010] Preferably, a support is provided at the bottom of the slide rail, and a smelting furnace and a slag collection cylinder are provided on one side of the support. A tray is provided at the bottom of both the smelting furnace and the slag collection cylinder.

[0011] Preferably, a push-pull motor is provided on the surface of the support, and the output end of the push-pull motor is connected to the sliding base.

[0012] Preferably, the top of the sliding base is provided with a track to match the sliding of the slider.

[0013] The beneficial effects of this invention are as follows: This invention sets up a sliding base on a slide rail, which is driven to slide back and forth by a push-pull motor. In this way, the whole structure can move back and forth. The sliding base is driven by a push motor to move a slider on the track, which causes the connecting arm to drive the lifting cylinder to move left and right. The lifting cylinder drives the mounting plate to move down, which in turn drives the collection box to move down. The collection box collects smelting slag through the opening into the collection box through the collection mechanism. Molten iron seeps out through the mesh plate. After collection, the smelting slag is transferred by the lifting cylinder, the push motor, and the movement of the sliding base. This invention can automatically collect and transfer smelting slag, which greatly improves production efficiency, ensures personal safety, and reduces labor costs.

[0014] The collection mechanism uses a horizontal pusher cylinder to drive the connecting plate to move laterally, which in turn moves the horizontal pusher plate laterally, thereby driving the collection inclined plate to move laterally. The horizontal pusher plate and the collection inclined plate push the smelting slag through the opening into the collection box for automatic collection. The horizontal pusher plate blocks the opening of the collection box to prevent the smelting slag from falling out. The horizontal pusher plate is also equipped with a guide plate to guide and gather the smelting slag for collection, further improving work efficiency.

[0015] The bottom mesh plate of the collection box is designed with the same inclination as the collection inclined plate, which causes the smelting slag to accumulate on one side. The smelting slag can be dropped by opening the door. Attached Figure Description

[0021] like Figures 1 to 3As shown, an automatic slag removal device for casting and smelting includes a sliding base 1. The sliding base 1 has a sliding rail 2 at its bottom for forward and backward movement. A push motor 3 is located at one end of the top of the sliding base 1. A slider 18 for left and right movement is fixedly connected to the output end of the push motor 3. One end of a connecting arm 4 is fixedly connected to the top of the slider 18. A lifting cylinder 5 is located at the bottom of the other end of the connecting arm 4. A mounting plate 6 is fixedly connected to the bottom output end of the lifting cylinder 5. A collection box 7 with an opening on one side is connected to the bottom of the mounting plate 6. The bottom of the collection box 7 is a perforated plate. A collection mechanism is located at the opening on the side of the collection box 7 to collect smelting slag into the collection box 7. A push-pull motor 17 is located on the surface of a support 14, and the output end of the push-pull motor 17 is connected to the sliding base 1. A track 19 matching the movement of the slider 18 is located on the top of the sliding base 1. By setting the sliding base 1 on the slide rail 2 and driving it to slide back and forth via the push-pull motor 17, the whole unit can move back and forth. The sliding base 1 is driven by the push motor 3 to drive the slider 18 to slide on the track 19, thereby causing the connecting arm 4 to drive the lifting cylinder 5 to move left and right. The lifting cylinder 5 drives the mounting plate 6 to move down, thereby driving the collection box 7 to move down. The collection box 7 collects the smelting slag through the opening into the collection mechanism. After the molten iron seeps out through the mesh plate, it is lifted by the lifting cylinder 5, moved by the push motor 3, and moved by the sliding base 1 to transfer the smelting slag. The smelting slag can be automatically collected and transferred, which greatly improves production efficiency, ensures personal safety, and reduces labor costs.

[0022] The collection mechanism includes a horizontal push cylinder 8 located at the top of the mounting plate 6 near the opening. A connecting plate 9 is connected to the output end of the horizontal push cylinder 8. A horizontal push vertical plate 10 is located at the bottom of the connecting plate 9, at the opening of the collection box 7. A collection inclined plate 11 is located at the bottom of the horizontal push vertical plate 10 near the opening. The horizontal push vertical plate 10 and the collection inclined plate 11 push the smelting slag through the opening onto the bottom mesh plate inside the collection box 7. The horizontal push vertical plate 10 can block the opening. Trumpet-shaped guide plates 12 are located on both sides of the horizontal push vertical plate 10 near the opening, with the bottom of the guide plates 12 positioned at the top of the collection inclined plate 11. The collection mechanism drives the connecting plate 9 to move laterally via the horizontal push cylinder 8, which in turn causes the horizontal push vertical plate 10 to move laterally, thereby driving the collection inclined plate 11 to move laterally. The horizontal push vertical plate 10 and the collection inclined plate 11 push the smelting slag through the opening into the collection box 7 for automatic collection. The horizontal push vertical plate 10 blocks the opening of the collection box 7 to prevent the smelting slag from falling out. The horizontal push vertical plate 10 is also equipped with a guide plate 12 to guide and gather the smelting slag for collection, further improving work efficiency.

[0023] The bottom mesh plate of the collection box 7 is inclined downwards towards the end furthest from the opening, and the inclination of the mesh plate is the same as that of the collection inclined plate 11. The end of the collection box 7 furthest from the opening is a door 13. The top of the door 13 is rotatably connected to the top of the collection box 7 via a hinge, and the bottom of the door 13 is fixed to the bottom of the collection box 7 via a lock. The design of the bottom mesh plate of the collection box 7 with the same inclination as the collection inclined plate 11 causes the smelting slag to accumulate to one side, allowing the smelting slag to fall out by opening the door 13.

[0024] The bottom of the slide rail 2 is provided with a support 14, and a smelting furnace 15 and a slag collection cylinder 16 are provided on one side of the support 14. The bottom of the smelting furnace 15 and the slag collection cylinder 16 are provided with a tray 20. The sliding base 1 is moved by the push-pull motor 17 to move the collection box 7 onto the smelting furnace 15 or the slag collection cylinder 16 to collect smelting slag.
