Description

Technical Field

[0001] The utility model relates to the technical field of ladle pouring, in particular to an automatic pouring device for producing ladle pouring material. Background Art

[0002] The automatic pouring device for ladle castings is mainly an industrial equipment used to evenly distribute refractory castables in the annular space between the core mold and the ladle. The application field of the automatic pouring device for ladle castings is mainly in the steel smelting and casting industries. In these fields, the automatic pouring device is used to improve the cleanliness of molten steel and ensure that the quality of steel meets increasingly higher standards. With the development of technology, these devices play an important role in improving production efficiency, reducing costs and environmental protection. In terms of development prospects, with the continuous advancement of industrial automation technology, the demand for automatic pouring devices for ladle castings is expected to continue to grow.

[0003] In the prior art, since the temperature of the casting material is usually very high, reaching 1100°C, this brings certain difficulties to mixing and handling. Under high temperature, the properties of many materials will change, and they may even fail to work normally. Therefore, in the pre-casting stage, it is difficult to find a material that can withstand such a high temperature while maintaining its characteristics and being effectively stirred. If the casting material is not uniform enough, it will lead to a series of problems. First, the uneven casting material will affect its fluidity, resulting in incomplete filling, excessive bubbles and other problems during the casting process. Secondly, the uneven casting material will lead to insufficient strength after casting, which will directly affect the performance and service life of the product. Finally, if the yield rate is reduced, it will not only increase production costs, but also lead to a decrease in production efficiency, and even affect the company's market competitiveness. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes an automatic pouring device for producing ladle casting material.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an automatic pouring device for producing ladle casting material, including a pouring device and a pouring mold, one side of the pouring device is rotatably connected to a bearing plate, the top of the bearing plate is fixed with an outer solid barrel, the circumferential surface of the outer solid barrel is fixed with a discharge nozzle, the inner wall of the outer solid barrel is rotatably connected to an inner rotating barrel, the inner wall circumferential surface of the inner rotating barrel is provided with a stirring inner thread, the surface of the inner rotating barrel is provided with a discharge inner square groove, the bottom end of the inner rotating barrel is fixed with a bottom outer edge, the circumferential surface of the bottom outer edge is fixed with an elliptical tooth, the surface of the elliptical tooth is meshed with an angular screw, the angular screw is driven by a motor, and the motor is arranged on the inner wall of the bearing plate. In the prior art, due to the pouring The temperature of the building material is usually very high, reaching 1100℃, which brings certain difficulties to mixing and handling. Under high temperature, the properties of many materials will change, or even fail to work properly. Therefore, in the pre-pouring stage, it is difficult to find a material that can withstand such high temperatures while maintaining its characteristics and being effectively stirred. If the uniformity of the casting material is insufficient, a series of problems will occur. First, the uneven casting material will affect its fluidity, resulting in incomplete filling, excessive bubbles, and other problems during the pouring process. Secondly, the uneven casting material will lead to insufficient strength after casting, which will directly affect the performance and service life of the product. Finally, if the yield rate is reduced, it will not only increase the production cost, but also increase the production cost. The utility model solves this problem by installing an inner rotating barrel, so that when production starts, the castable is injected into the inner rotating barrel. At this time, the staff starts the motor to drive the angle screw to start rotating, and the angle screw meshes with the elliptical teeth. This mechanical action pushes the outer edge of the bottom, and then the inner rotating barrel starts to rotate. This rotational motion causes the stirring internal thread to push the castable upward, and then the castable falls again. This cycle is repeated to achieve continuous stirring of the castable in the inner rotating barrel. Through such a stirring process, the solute precipitation can be effectively prevented, ensuring that the composition and temperature of the castable remain uniform. First, this is crucial to ensure the quality of the final product. At the same time, the coordinated design of the outer solid barrel and the inner rotating barrel not only reduces the impact of the high-temperature castable on the equipment body, but also facilitates the disassembly, maintenance and replacement of the inner rotating barrel. This design greatly reduces the maintenance cost of the equipment and improves production efficiency. In addition, this design also helps to improve the safety of the working environment, because the staff does not need to directly contact the high-temperature castable, thereby reducing burns and other related risks. At the same time, since the equipment is easy to maintain and replace, this helps to reduce production interruptions caused by equipment failures, ensure the continuity and stability of the production process, and achieve the effect of improving the yield and reducing maintenance costs.

[0006] Preferably, an outer discharging groove is provided at one end of the discharging nozzle, and the area of ​​the outer discharging groove is equal to the area of ​​the inner square discharging groove. In the prior art, the pouring equipment will accurately pour the high-temperature pouring material in the inner rotating barrel into the pre-set pouring mold according to the predetermined procedure and trajectory. This process needs to be strictly controlled to ensure that the mold can accurately reach the specified position so that the pouring material can be smoothly and safely injected. However, if the operator makes an error in operation or the pouring equipment itself fails, then before the pouring mold reaches the predetermined position, the inner rotating barrel will be skewed, resulting in the high-temperature pouring material being unable to follow the predetermined path. Instead of flowing into the mold, it overflows from the barrel. Once the high-temperature castable overflows, it will not only damage the equipment, but also cause harm to the operating personnel, and even cause larger-scale production accidents, such as fire or explosion, causing serious damage to the entire production facilities. In view of such problems, the utility model solves them by providing an outer discharge trough and an inner square discharge trough. When the casting mold has not reached the predetermined position, the rotation of the inner rotating barrel makes the outer discharge trough and the inner square discharge trough misaligned. Even if the inner rotating barrel is accidentally skewed, the castable cannot be completely dumped out. In addition, the degree of safety accidents is limited, thereby achieving the effect of improving production safety.

[0007] Preferably, stirring rifling lines are provided on the inner wall of the discharge nozzle. In the prior art, when the castable is poured by its own gravity, its flow rate is limited by various factors, which often leads to a slower outflow rate. This slow flow rate not only prolongs the time of the entire pouring process and reduces production efficiency, but also leads to increased formation of bubbles during the pouring process, affecting the density and quality of the final product. To address such problems, the utility model solves them by providing stirring rifling lines, so that when the staff starts pouring, the castable moves along the stirring rifling lines to produce a vortex effect, greatly increasing the outflow rate. At the same time, the staff can further increase the flow rate by pressurizing the inward rotating barrel. Due to the existence of the vortex effect, the pressurization force can be further increased without backflow, thereby achieving the effect of improving production efficiency.

[0008] Preferably, a circumferential pressure baffle is fixed on the top of the inner rotating barrel to reduce the exposed area of ​​the top of the inner rotating barrel, prevent the castable from splashing, and improve production safety.

[0009] Preferably, the discharge nozzle is set to be trapezoidal, so that the center of gravity of the component moves backward, reducing the energy consumption required for rotation and resetting, and reducing production costs.

[0010] Preferably, the inner square groove for discharging is configured as a cuboid, and the long side direction of the inner square groove for discharging is perpendicular to the top surface of the supporting plate, so that most of the castable material falls when passing through the inner square groove for discharging, thereby accelerating the stirring speed.

[0011] Preferably, the bottom of the inner wall of the discharge nozzle is higher than the bottom of the outer discharge trough, thereby increasing the angle required for discharge and preventing production accidents.

[0012] Beneficial Effects

[0013] 1. In the prior art, since the temperature of the casting material is usually very high, reaching 1100°C, this brings certain difficulties to mixing and handling. Under high temperature, the properties of many materials will change, and they may even fail to work normally. Therefore, in the pre-casting stage, it is difficult to find a material that can withstand such a high temperature while maintaining its characteristics and being effectively stirred. If the uniformity of the casting material is insufficient, a series of problems will occur. First, the uneven casting material will affect its fluidity, resulting in incomplete filling, excessive bubbles and other problems during the casting process. Secondly, the uneven casting material will lead to insufficient strength after casting, which will directly affect the performance and service life of the product. Finally, if the yield rate is reduced, it will not only increase the production cost, but also lead to a decrease in production efficiency, and even affect the market competitiveness of the enterprise. In response to such problems, the utility model adopts the method of installing an inner rotating barrel to solve the problem, so that when production starts, the casting material is injected into the inner rotating barrel. At this time, the staff starts the motor to drive the angle screw to start rotating, and the angle screw and the elliptical toggle The teeth mesh with each other, and this mechanical action pushes the outer edge of the bottom, which in turn causes the inner rotating barrel to start rotating. This rotational motion causes the stirring internal thread to push the castable upwards, and then the castable falls again, and this cycle is repeated to achieve continuous stirring of the castable in the inner rotating barrel. Through this stirring process, the solute precipitation can be effectively prevented to ensure that the composition and temperature of the castable remain uniform, which is crucial to ensuring the quality of the final product. At the same time, the coordinated design of the outer solid barrel and the inner rotating barrel not only reduces the impact of high-temperature castables on the equipment body, but also facilitates the disassembly, maintenance and replacement of the inner rotating barrel. This design greatly reduces the maintenance cost of the equipment and improves production efficiency. In addition, this design also helps to improve the safety of the working environment, because the staff does not need to directly contact the high-temperature castable, thereby reducing scalding and other related risks. At the same time, since the equipment is easy to maintain and replace, this helps to reduce production interruptions caused by equipment failures, ensure the continuity and stability of the production process, and achieve the effect of improving the yield and reducing maintenance costs.

[0014] 2. In the prior art, the pouring equipment will accurately pour the high-temperature castable material in the inner rotating barrel into the pre-set pouring mold according to the predetermined procedure and trajectory. This process needs to be strictly controlled to ensure that the mold can accurately reach the specified position so that the castable material can be smoothly and safely injected. However, if the operator makes an error in operation or the pouring equipment itself fails, the inner rotating barrel will be skewed before the pouring mold reaches the predetermined position, resulting in the high-temperature castable material being unable to flow into the mold according to the established path, but overflowing from the barrel. Once the high-temperature castable overflows, it will not only damage the equipment, but also cause harm to the operator, and even cause larger-scale production accidents, such as fire or explosion, causing serious damage to the entire production facility. In response to such problems, the utility model solves the problem by providing an outer discharging trough and an inner square discharging trough, so that when the pouring mold has not reached the predetermined position, the rotation of the inner rotating barrel makes the outer discharging trough and the inner square discharging trough misaligned. Even if the inner rotating barrel is accidentally skewed, the castable material cannot be completely dumped out, and the degree of safety accidents is limited, thereby achieving the effect of improving production safety.

[0015] 3. In the prior art, when the castable is poured by its own gravity, its flow rate is limited by many factors, which often leads to a slower outflow rate. This slow flow rate not only prolongs the time of the entire pouring process and reduces production efficiency, but also leads to an increase in the formation of bubbles during the pouring process, affecting the density and quality of the final product. To address this problem, the utility model solves it by opening a stirring rifling line, so that when the staff starts pouring, the castable moves along the stirring rifling line to produce a vortex effect, which greatly increases the outflow rate. At the same time, the staff can further increase the flow rate by pressurizing the inward rotating barrel. Due to the existence of the vortex effect, the pressurization force can be further increased without backflow, thereby achieving the effect of improving production efficiency.

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments and drawings, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0023] The specific embodiments of the present utility model are described below in conjunction with the accompanying drawings. Specific embodiment:

[0025] Reference Figure 1-4, an automatic pouring device for producing ladle casting material, comprising a pouring device 1 and a pouring mold 101, one side of the pouring device 1 is rotatably connected to a carrying plate 2, an outer solid barrel 201 is fixed on the top of the carrying plate 2, a discharge nozzle 3 is fixed on the circumference of the outer solid barrel 201, an inner rotating barrel 202 is rotatably connected to the inner wall of the outer solid barrel 201, a stirring inner thread 205 is provided on the circumference of the inner wall of the inner rotating barrel 202, a discharge inner square groove 204 is provided on the surface of the inner rotating barrel 202, a bottom outer edge 206 is fixed to the bottom end of the inner rotating barrel 202, an elliptical tooth 207 is fixed on the circumference of the bottom outer edge 206, an angular screw 208 is meshed on the surface of the elliptical tooth 207, and the angular screw 208 is driven by a motor, and the motor is arranged on the inner wall of the carrying plate 2. Due to the temperature of the casting material, the The temperature is usually very high, reaching 1100℃, which brings certain difficulties to mixing and processing. Under high temperature, the properties of many materials will change, or even fail to work properly. Therefore, in the pre-pouring stage, it is difficult to find a material that can withstand such high temperatures while maintaining its characteristics and being effectively stirred. If the uniformity of the pouring material is insufficient, a series of problems will occur. First, the uneven pouring material will affect its fluidity, resulting in incomplete filling, excessive bubbles, and other problems during the pouring process. Secondly, the uneven pouring material will lead to insufficient strength after pouring, which will directly affect the performance and service life of the product. Finally, if the yield rate is reduced, it will not only increase the production cost, but also lead to production The efficiency is reduced, and even the market competitiveness of the enterprise is affected. The solution is to install an inner rotating barrel 202. When production starts, the castable is injected into the inner rotating barrel 202. At this time, the staff starts the motor to drive the angle screw 208 to start rotating. The angle screw 208 meshes with the elliptical tooth 207. This mechanical action pushes the bottom outer edge 206, and then the inner rotating barrel 202 starts to rotate. This rotational motion causes the stirring internal thread 205 to push the castable upwards, and then the castable falls again. This cycle achieves continuous stirring of the castable in the inner rotating barrel 202. Through this stirring process, the solute precipitation can be effectively prevented, ensuring that the composition and temperature of the castable remain uniform. It is crucial to ensure the quality of the final product. At the same time, the coordinated design of the outer solid barrel 201 and the inner rotating barrel 202 not only reduces the impact of the high-temperature castable on the equipment body, but also facilitates the disassembly, maintenance and replacement of the inner rotating barrel 202. This design greatly reduces the maintenance cost of the equipment and improves production efficiency. In addition, this design also helps to improve the safety of the working environment, because the staff does not need to directly contact the high-temperature castable, thereby reducing burns and other related risks. At the same time, since the equipment is easy to maintain and replace, this helps to reduce production interruptions caused by equipment failures, ensure the continuity and stability of the production process, and achieve the effect of improving the yield and reducing maintenance costs.An outer discharging groove 301 is provided at one end of the discharging nozzle 3, and the area of ​​the outer discharging groove 301 is equal to the area of ​​the inner square discharging groove 204. The pouring equipment 1 will accurately pour the high-temperature pouring material in the inner rotating barrel 202 into the pre-set pouring mold 101 according to the predetermined program and trajectory. This process needs to be strictly controlled to ensure that the mold can accurately reach the specified position so that the pouring material can be smoothly and safely injected. However, if the operator makes a mistake in operation, or the pouring equipment 1 itself fails, then before the pouring mold 101 reaches the predetermined position, the inner rotating barrel 202 will be skewed, resulting in the high-temperature pouring material being unable to flow according to the predetermined path. Instead of flowing into the mold, the high-temperature castable overflows from the barrel. Once the high-temperature castable overflows, it will not only damage the equipment, but also cause harm to the operator, and even cause a larger-scale production accident, such as fire or explosion, causing serious damage to the entire production facility. The problem is solved by opening an outer discharge trough 301 and an inner discharge square trough 204. When the casting mold 101 has not reached the predetermined position, the rotation of the inner rotating barrel 202 makes the outer discharge trough 301 and the inner discharge square trough 204 misaligned. Even if the inner rotating barrel 202 is accidentally tilted, the castable cannot be completely dumped out. In addition, the degree of safety accidents is limited, achieving the effect of improving production safety. A peripheral pressure baffle 203 is fixed on the top of the inner rotating barrel 202 to reduce the exposed area of ​​the top of the inner rotating barrel 202, prevent the castable from splashing, and improve production safety.

[0026] The inner wall of the discharge nozzle 3 is provided with a stirring rifling line 302. When the castable is poured by its own gravity, its flow rate is limited by many factors, which often leads to a slow outflow rate. This slow flow rate not only prolongs the time of the entire casting process and reduces production efficiency, but also leads to an increase in the formation of bubbles during the casting process, affecting the density and quality of the final product. The solution is to open a stirring rifling line 302, so that when the staff starts casting, the castable moves along the stirring rifling line 302, generating a vortex effect, greatly increasing the outflow rate. At the same time, the staff can further increase the flow rate by pressurizing the inner rotating barrel 202. Due to the existence of the vortex effect, the pressure can be further increased without backflow, thereby achieving the effect of improving production efficiency. The discharge nozzle 3 is set to a trapezoidal shape, so that the center of gravity of the component moves backward, reducing the energy consumption required for rotation and reset, and reducing production costs. The inner square groove 204 of the material discharging is set as a rectangular parallelepiped, and the long side direction of the inner square groove 204 of the material discharging is perpendicular to the top surface of the carrier plate 2, so that most of the castables fall when passing through the inner square groove 204 of the material discharging, and the stirring speed is accelerated. The bottom of the inner wall of the material discharging nozzle 3 is higher than the bottom of the outer groove 301 of the material discharging, which increases the angle required for discharging and prevents production accidents.

[0027] The working principle of the utility model is as follows: when production starts, the castable is injected into the inner rotating barrel 202. At this time, the staff starts the motor to drive the angle screw 208 to start rotating. The angle screw 208 meshes with the elliptical tooth 207. This mechanical action pushes the bottom outer edge 206, and then the inner rotating barrel 202 starts to rotate. This rotational motion causes the stirring inner thread 205 to push the castable upward, and then the castable falls again. This cycle achieves continuous stirring of the castable in the inner rotating barrel 202. When the casting mold 101 has not reached the predetermined position, the rotation of the inner rotating barrel 202 causes the outer discharge groove 301 to be misaligned with the inner square groove 204 of the discharge. Even if the inner rotating barrel 202 is accidentally tilted, the castable cannot be completely poured out. When the staff starts pouring, the castable moves along the stirring rifling line 302, generating a vortex effect, greatly increasing the outflow speed. At the same time, the staff can further increase the flow speed by pressurizing the inner rotating barrel 202.
