Description

Technical Field

[0001] This utility model relates to the field of metal refining equipment, specifically to a high-efficiency slag-liquid separation refining furnace. Background Technology

[0002] In the field of aluminum refining, the separation of slag from molten metal is a key step in improving product purity. In traditional processes, this process is mostly done manually. The specific procedure is as follows: workers use long-handled tools (such as slag scoops) to directly reach into the inner liner of the high-temperature furnace and manually scoop up the slag floating on the surface of the molten metal, and then transfer the slag to an external collection container.

[0003] In existing technologies, manual slag removal requires sequential operations, with a limited amount of slag removed per operation. Furthermore, it is constrained by the worker's pace and physical strength, and the high ambient temperature makes continuous separation difficult. For large-scale production scenarios, the separation time for a single furnace cycle typically lasts several hours, severely limiting overall production efficiency.

[0004] Therefore, it is necessary to invent a high-efficiency slag-liquid separation and refining furnace to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a high-efficiency slag-liquid separation refining furnace. A transmission mechanism drives the collecting component in the separation assembly to rotate. Utilizing the inclined structure of the front side of the collecting component, which is lower than the aluminum molten liquid surface, and its asymmetrical bending design, continuous "scooping" of floating slag is achieved. Simultaneously, the containment function of the protective plate and the guiding design of the discharge chute guide the slag to be temporarily stored on the storage plate, reducing metal entrainment. This allows the aluminum molten liquid to flow back through the hollow area at the bottom of the collecting component and the discharge chute, improving slag-liquid separation efficiency and reducing metal loss. This solves the problems of low efficiency, difficulty in continuous operation, high labor intensity, and unstable separation quality associated with manual slag removal in existing technologies.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency slag-liquid separation and refining furnace, comprising...

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] This utility model provides, for example Figure 1 - Figure 3 The high-efficiency slag-liquid separation and refining furnace shown includes a heating furnace 1 and a separation component 4.

[0025] Heating furnace 1 supports the entire device and provides a heating environment for the inner liner 2 and the molten aluminum inside. It maintains the high temperature required for refining through built-in electric heating elements to adapt to the molten metal state, ensuring that the slag-liquid separation process takes place at a stable temperature. The inner liner 2, which directly holds the molten aluminum and slag, is installed on the inner wall of heating furnace 1 and is made of high-temperature resistant and corrosion-resistant refractory ceramic. A lifting mechanism 3, including a hydraulic cylinder and an electric telescopic rod, is fixedly connected to the left side of heating furnace 1. The telescopic movement of the output shaft drives the moving plate 7 and the separation component 4 above it to move up and down, realizing the separation of the separation component 4 and the molten aluminum in the inner liner 2. The height of the liquid level is adapted to meet the slag removal requirements under different liquid levels. The upper part of the output shaft of the lifting mechanism 3 is rotatably connected to the moving plate 7, which is the intermediate component connecting the lifting mechanism 3 and the transmission mechanism 6. A limit component 5 is set between the lifting mechanism 3 and the moving plate 7. The transmission mechanism 6 is fixedly installed on the outside of the moving plate 7, which consists of a motor, two sets of sprockets, a set of output shafts, a rotating shaft and a set of chains. The two sets of sprockets are respectively installed on the upper part of the motor and the rotating shaft. The rotating shaft is the output end of the transmission mechanism 6 and is rotatably connected to the inner wall of the moving plate 7 through bearings. It is connected by sprocket and chain transmission, thereby driving the separation component 4 to rotate.

[0026] Separation component 4 is used for transmission connection with transmission mechanism 6. The material used for components of separation component 4 is 310S stainless steel, with a melting point range of 1400℃-1450℃. It has excellent high-temperature resistance and can maintain good mechanical strength and oxidation resistance in high-temperature environments. It can adapt to the melting point of molten aluminum of about 660℃ and the high-temperature working environment in heating furnace 1, avoiding deformation or failure due to excessive temperature. Separation component 4 includes a connecting rod 41 fixedly connected to the output end of transmission mechanism 6, a rigid rod connecting transmission mechanism 6 and connecting member 42, and transmits the rotational power of transmission mechanism 6 to the storage plate 43 and collection member 45 below. A connecting member 42 is fixedly installed on the lower part of the connecting rod 41 by bolts. This is used to stably install the storage plate 43 on the connecting rod 41, ensuring the structural stability of the storage plate 43 and the collecting member 45 during rotation. The storage plate 43 is horizontally fixedly connected to the outside of the connecting member 42, serving as a temporary support platform for slag. The slag guided by the collecting member 45 is temporarily piled up here. The molten aluminum entrained is discharged through the discharge chute 46 of the guard plate 44. The collecting member 45 is fixedly connected to the front of the storage plate 43. This is the slag-liquid separation execution component. The guard plate 44 is fixedly connected to the outer periphery of the collecting member 45 and the storage plate 43, acting as a "barrier" to guide the slag.

[0027] like Figure 1 - Figure 3 As shown, the rear side of the guard plate 44 is designed as an arc surface to adapt to the rotation trajectory and reduce motion resistance. The front right side of the guard plate 44 is designed as a horizontal surface, which, together with the discharge chute 46, prevents slag backflow. The discharge chute 46 is provided through the inner wall of the front side of the guard plate 44. The discharge chute 46 has multiple through slots to guide the molten aluminum on the storage plate 43 to be discharged in a directional manner and reduce slag discharge. The front quarter of the collecting component 45 is bent forward and upward, and the rear two-quarters of the collecting component 45 is bent backward and upward, forming an asymmetrical inclined structure that can efficiently "scoop up" floating slag. The rear side of the collecting component 45 is fixedly connected to the front left side of the storage plate 43. The lower part of the collecting component 45 is hollow, allowing the attached molten aluminum to flow back to the inner liner 2, leaving only slag on the storage plate 43. The front height of the collecting component 45 is lower than the rear height, and the bent part of the front of the collecting component 45 is lower than the molten metal surface to ensure full contact with the slag layer.

[0028] like Figure 1 , Figure 2 and Figure 4As shown, the limiting component 5 includes a base 51, which is fixedly connected to the upper part of the lifting mechanism 3, providing an installation base for the connector 52. The base 51 is located around the output shaft of the lifting mechanism 3 to avoid interfering with the telescopic movement of the output shaft. The connector 52 is fixedly connected to the upper part of the base 51, cooperating with the connector rod 54 below the moving plate 7. It plays a guiding role when the moving plate 7 is raised and lowered, and limits the horizontal direction of the moving plate 7 after insertion, improving the stability of the separation component 4 during operation. A connecting ring 53 is fixedly connected to the lower part of the moving plate 7 for installing the connector rod 54 and transmitting the force of the moving plate 7 to the limiting component 5. Two sets of connector rods 54 are vertically fixedly connected to the lower part of the connecting ring 53 to limit the radial displacement of the moving plate 7. The connector rods 54 are inserted into the inner wall of the connector 52. The connector 52 is flared to facilitate quick alignment and insertion of the connector rods 54, reducing alignment deviation.

[0029] The working principle of this utility model is as follows: After the heating furnace 1 is started, it generates high temperature through the built-in electric heating element, so that the inner liner 2 reaches the temperature required for melting aluminum. After the temperature stabilizes, molten aluminum containing slag is injected into the inner liner 2. Because the slag has a low density, it naturally floats on the surface of the molten aluminum, preparing for subsequent separation.

[0030] The lifting mechanism 3 drives the output shaft to extend, and the moving plate 7 can rotate flexibly around the output shaft of the lifting mechanism 3, so that the plug rod 54 below the connecting ring 53 is aligned with the trumpet-shaped plug 52 on the base 51. At this time, the lifting mechanism 3 drives the output shaft to extend and retract, driving the separation component 4 to move up and down until the front side of the collecting component 45 is lower than the aluminum liquid surface. At this time, the front bend of the collecting component 45 is immersed in the slag layer, while the rear is higher than the liquid surface, forming an inclined "scooping" posture.

[0031] Meanwhile, in the limiting component 5, the plug rod 54 below the connecting ring 53 is inserted into the trumpet-shaped plug 52 on the base 51, and radial limiting ensures the stability of the moving plate 7 and the separation component 4, preventing shaking.

[0032] The transmission mechanism 6, consisting of a motor, sprocket, chain, and rotating shaft, is activated. The chain drive rotates the connecting rod 41, which in turn drives the connecting piece 42, the storage plate 43, and the collecting piece 45 to rotate synchronously. The collecting piece 45 utilizes an asymmetrical structure where the front quarter bends forward and upward and the rear half bends backward and upward, to "scoop up" the floating slag during rotation. Because the front side is lower than the rear side, the slag is guided to the storage plate 43 according to the tilt angle. The entrained molten aluminum flows back to the inner tank 2 through the hollow area at the bottom of the collecting piece 45 and the discharge chute 46 on the front side of the guard plate 44, leaving only the slag temporarily stored in the storage plate 43. After the operation is completed, the lifting mechanism 3 lifts the separation component 4 away from the liquid surface, and the transmission mechanism 6 stops running, completing one slag-liquid separation cycle.

[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
