Description

Technical Field

[0001] This utility model relates to the technical field of furnace charging auxiliary equipment, and in particular to an automatic charging device for an electroslag furnace. Background Technology

[0002] In many industrial sectors such as metal smelting and glass manufacturing, furnaces are indispensable key equipment, and the supporting feeding devices play a crucial role in the efficient operation of the furnaces. Currently, screw feeders are widely used in furnace feeding due to their relatively simple structure and stable conveying characteristics. They mainly utilize the rotation of the screw shaft within the material cylinder, employing the pushing action of the screw blades to transport materials from a lower position to the furnace inlet.

[0003] However, existing screw feeders have some significant problems. First, for viscous or easily agglomerated materials, these materials tend to accumulate at the discharge port of the cylinder during transport. Over time, the accumulated material increases, eventually causing blockage at the discharge port. Once the discharge port is blocked, the feeding process is forced to stop, which not only affects the normal continuous operation of the furnace and reduces production efficiency, but may also adversely affect product quality due to untimely material supply. For example, in glass manufacturing, discontinuous feeding may lead to uneven composition of the molten glass, affecting the quality of glass products.

[0004] Secondly, the discharge position of existing feeding devices is usually fixed. However, in actual production, the position of the furnace inlet may change due to adjustments in the production process, changes in equipment layout, or the need to adapt to different furnace models. In this case, feeding devices with fixed discharge positions cannot flexibly adjust the discharge direction and position, making it difficult to meet the diverse needs of actual production and greatly limiting their applicability. For example, when a company replaces a furnace with a new model whose inlet position differs from the original furnace, the existing feeding device may no longer be usable, requiring the purchase or modification of new equipment, increasing the company's production and time costs.

[0005] In summary, existing spiral feeding devices suffer from problems such as material accumulation and blockage, and the discharge position is not adjustable, which seriously affects the charging efficiency of the furnace and the applicability of the device. Therefore, developing a furnace feeding device that can effectively clear accumulated material and flexibly adjust the discharge position is of significant practical importance. It will help improve the production efficiency of related industries, reduce production costs, and ensure the stability of product quality. Utility Model Content

[0006] To overcome existing problems, this application provides an automatic feeding device for an electroslag furnace, which solves the problems of material accumulation and blockage and the inability to adjust the discharge position that occur in the existing screw feeder during the feeding process of the furnace, thereby improving the continuity of feeding and the applicability of the device.

[0007] The technical solution adopted by the embodiments of this application to solve its technical problem is: An automatic feeding device for an electroslag furnace includes a screw feeding mechanism and an air blowing assembly; The top of the spiral feeding mechanism is provided with a discharge port. The air blowing component is installed on the top of the discharge port and has a cylinder body at one end. The cylinder body is detachably installed at the discharge port. A connecting block is provided at the intersection of the cylinder body and the discharge port. The cylinder body and the discharge port can be fixed by the connecting block. The air blowing assembly includes a connecting plate connected to the cylinder body. A support is provided below the connecting plate, and a micro motor is embedded inside the support. The support is made of die-cast aluminum alloy and has mounting holes machined inside to fit the micro motor. A fixed seat is provided at the output end of the micro motor. A rotating shaft is provided at the end of the fixed seat away from the air blowing pipe. The rotating shaft is connected to the output end of the micro motor and is used to drive the rotating shaft to rotate. An air blowing pipe is snapped into the fixed seat and is connected to an external air source. When material accumulation is found at the outlet, the switch of the cylinder body is turned on. Under the operation of the cylinder body, the air blowing assembly is moved to the outside of the outlet. Then, the micro motor is started, which drives the air blowing pipe to rotate and tilt. At the same time, the external air source valve is opened, so that compressed air is sprayed out through the air blowing pipe to clean the outlet from all directions and blow off the accumulated material.

[0008] Preferably, the support is further provided with a limiting plate at one end near the cylinder body. When the cylinder body drives the air blowing assembly to move, the limiting plate slides on the upper surface of the discharge port, and the maximum sliding length is less than the total length of the limiting plate and the support.

[0009] Preferably, the spiral feeding mechanism includes a spiral conveying pipe, a spiral shaft, and a servo motor. The spiral shaft is rotatably installed inside the spiral conveying pipe, and there is a gap between the spiral shaft and the inner wall of the spiral conveying pipe. The bottom end of the spiral shaft is connected to the servo motor, and the top end of the spiral shaft is provided with a bearing. The servo motor is fixed to one end of the spiral conveying pipe, and its output end is connected to the spiral shaft for transmission. The top end of the spiral conveying pipe is provided with a discharge port on the side away from the servo motor. When the servo motor runs, it drives the internal spiral shaft to rotate. Then, the material in the inlet moves upward through the rotation of the spiral shaft and finally falls out from the discharge port.

[0010] Preferably, the spiral feeding mechanism further includes a base, which supports the overall structure. The base is provided with a feed inlet at the intersection with the spiral conveying pipe. Raw materials are poured in from the feed inlet, and then the material from the feed inlet is conveyed to the discharge outlet by the rotation of the spiral shaft inside the spiral conveying pipe.

[0011] The advantages of the embodiments of this application are: An air blowing assembly is installed at the top of the discharge port of the spiral feeding mechanism. One end of the air blowing assembly is connected to the cylinder body, and it is detachably installed at the discharge port through the cylinder body for easy disassembly and maintenance when needed. The air blowing assembly includes a connecting plate connected to the cylinder body, and a support is set below the connecting plate. A micro motor is embedded in the support, and the output end of the micro motor is connected to a fixed base. An air blowing pipe is snapped into the fixed base and connected to an external air source. When material accumulates at the discharge port, the micro motor is started, which drives the fixed base and the air blowing pipe to rotate. At the same time, the external air source supplies air to the air blowing pipe, so that the airflow sprayed by the air blowing pipe can clean the discharge port from all directions, blow off the residual material, effectively prevent the material from clogging the discharge port, and ensure the continuity of feeding.

[0012] By rationally designing the shape, diameter, and position and angle of the air blowing pipe, the airflow can be more precisely applied to the areas prone to material accumulation at the discharge port. The air blowing pipe is designed with a curved shape to better conform to the contour of the discharge port, increasing the cleaning range. Adjusting the angle of the air blowing nozzle allows the airflow to be ejected at a certain angle, enhancing the impact on the accumulated material and improving the cleaning effect. The speed of the micro motor can be adjusted according to the severity of the material accumulation. For cases with more or more stubborn material accumulation, increasing the speed of the micro motor will accelerate the rotation speed of the air blowing pipe and enhance the cleaning force.

[0016] This application provides an automatic feeding device for an electroslag furnace, solving the problems in the prior art. An air-blowing component is installed at the top of the discharge port of the screw feeder. One end of the air-blowing component is connected to the cylinder body, allowing for detachable installation at the discharge port via the cylinder body, facilitating disassembly and maintenance when needed. The air-blowing component includes a connecting plate connected to the cylinder body, with a support below the connecting plate. A micro motor is embedded inside the support, and the output end of the micro motor is connected to a fixed base. An air-blowing pipe is snapped into the fixed base and connected to an external air source. When material accumulates at the discharge port, the micro motor is activated, rotating the fixed base and the air-blowing pipe. Simultaneously, the external air source supplies air to the air-blowing pipe, enabling the airflow from the pipe to thoroughly clean the discharge port, blowing off any remaining material and effectively preventing blockage, thus ensuring continuous feeding.

[0017] The technical solution in this application is to solve the above problems, and the overall approach is as follows: Example This embodiment provides a specific structure of an automatic feeding device for an electroslag furnace, such as... Figure 1-5 As shown, it includes a spiral feeding mechanism and an air blowing assembly 6; The top of the spiral feeding mechanism is provided with a discharge port 4. The air blowing component 6 is installed on the top of the discharge port 4 and a cylinder body 5 is provided at one end. The cylinder body 5 is detachably installed at the discharge port 4. A connecting block is provided at the intersection of the cylinder body 5 and the discharge port 4. The cylinder body 5 can be fixed to the discharge port through the connecting block. The air blowing assembly 6 includes a connecting plate 62 connected to the cylinder body 5. A support 61 is provided below the connecting plate 62. A micro motor 64 is embedded inside the support 61. The support 61 is made of die-cast aluminum alloy and has mounting holes that are compatible with the micro motor 64. A fixing seat 65 is provided at the output end of the micro motor 64. A rotating shaft 67 is provided at the end of the fixing seat 65 away from the air blowing pipe 66. The rotating shaft 67 is connected to the output end of the micro motor 64 and is used to drive the rotating shaft 67 to rotate. The air blowing pipe 66 is snapped into the fixing seat 65 and is connected to an external air source.

[0018] Furthermore, when material accumulation is found at the discharge port 4, the switch of the cylinder body 5 is turned on. Under the operation of the cylinder body 5, the air blowing component 6 is moved to the outside of the discharge port 4. Then, the micro motor 64 is started, which drives the air blowing pipe 66 to rotate and tilt. At the same time, the external air source valve is opened, so that compressed air is sprayed out through the air blowing pipe 66 to clean the discharge port 4 from all directions and blow off the accumulated material.

[0019] A limiting plate 63 is also provided at one end of the support 61 near the cylinder body 5. When the cylinder body 5 drives the air blowing component 6 to move, the limiting plate 63 slides on the upper surface of the discharge port 4, and the maximum sliding length is less than the total length of the limiting plate 63 and the support 61.

[0020] Furthermore, the maximum output distance of the cylinder body 5 is less than the total length of the limiting plate 63 and the support 61, so that the limiting plate 63 can limit the air blowing assembly 6.

[0021] The spiral feeding mechanism includes a spiral conveying pipe 3, a spiral shaft 7, and a servo motor 8. The spiral shaft 7 is rotatably installed inside the spiral conveying pipe 3. There is a gap between the spiral shaft 7 and the inner wall of the spiral conveying pipe 3. The bottom end of the spiral shaft 7 is connected to the servo motor 8. The top end of the spiral shaft 7 is provided with a bearing. The servo motor 8 is fixed at one end of the spiral conveying pipe 3 and its output end is connected to the spiral shaft 7 for transmission. The top end of the spiral conveying pipe 3 is provided with a discharge port 4 on the side away from the servo motor 8.

[0022] Furthermore, the servo motor 8 runs, driving the internal spiral shaft 7 to rotate. Since the top of the spiral shaft 7 is equipped with a bearing, the spiral shaft 7 reduces friction when rotating. Moreover, during the rotation, the material at the bottom is transported to a higher position. That is, the material in the feed port 2 is moved upward by the spiral shaft 7 and finally falls from the discharge port 4.

[0023] The spiral feeding mechanism also includes a base 1, which supports the overall structure. The base 1 and the spiral conveying pipe 3 are provided with a feed inlet 2.

[0024] Furthermore, the raw material is poured in from the feed inlet 2, and then the material from the feed inlet 2 is transported to the discharge outlet 4 by the rotation of the spiral shaft 7 inside the spiral conveying pipe 3. When material accumulation is found in the discharge outlet 4, the switch of the cylinder body 5 is turned on. Under the operation of the cylinder body 5, the air blowing component 6 is moved to the outside of the discharge outlet 4. Then, the micro motor 64 is started, which drives the air blowing pipe 66 to rotate and tilt. At the same time, the external air source valve is opened, so that compressed air is sprayed out through the air blowing pipe 66 to clean the discharge outlet 4 from all directions and blow off the accumulated material.

[0025] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
