Description
Technical Field
[0001] The utility model relates to the technical field of vibrating feeders, in particular to a feeder for an industrial electric furnace. Background Art
[0002] As an important equipment in the metallurgical industry, industrial electric furnaces are widely used in the smelting and heating processes of materials such as steel and nonferrous metals. In the material feeding process of electric furnaces, vibrating feeders have become indispensable conveying equipment in industrial production due to their advantages such as uniform feeding and high efficiency. However, with the diversification and flexibility of production processes, existing vibrating feeders have exposed some significant deficiencies in actual use.
[0003] Existing vibration feeding equipment is usually composed of a silo, a hopper and a vibration component, but the silo and the hopper usually adopt a fixed structure. Although this structure makes the equipment structure simple and reduces the cost, it has high stability, is suitable for continuous transportation of large quantities of materials, and has good reliability. However, in the process scenario of multiple stations or multiple furnace ports, it is difficult for the equipment to adapt to the requirements of multi-position feeding, which limits the flexibility and adaptability of the equipment. In particular, when one feeder corresponds to multiple furnace ports, frequent adjustments are required, which is inefficient. In addition, because the inclination angle of the hopper is usually fixed, the material feeding speed is fixed during the vibration feeding process. At the same time, because the materials are accumulated in the silo, although the materials are continuously dispersed and discharged from the hopper during the vibration process, the accumulated materials collapse directly from the middle to the periphery, especially when feeding powder materials, the situation is more obvious, which will lead to more materials in the middle section and relatively less front and rear sections of the feeding. This makes the equipment unable to cope with different material characteristics or feeding speed control. Utility Model Content

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0033] Reference Figure 1-Figure 3 The utility model provides an embodiment: a feeder for an industrial electric furnace, comprising a base 1, a horizontal adjustment component is installed on the top of the base 1, the horizontal adjustment component comprises a slider 2, the slider 2 is slidably connected inside the base 1, an electric push rod 3 14 is fixedly connected to the outside of the slider 2, the other end of the electric push rod 3 14 is fixedly connected to the top of the base 1, when the electric push rod 3 14 is driven to work, the slider 2 can be driven to slide inside the base 1, thereby adjusting the position of the slider 2, a side plate 17 is fixedly connected to the outside of the base 1, a notch 18 is opened on the outer wall of the side plate 17, the slider 2 is slidably connected to the middle part of the side plate 17, and the purpose of adding the side plate 17 is to increase the range of movement of the slider 2, thereby further improving the feeding range of the feeder.
[0034] Reference Figure 1 , Figure 2 and Figure 4 , a gear ring seat 3 is installed on the top of the horizontal adjustment component, a reduction motor 15 is fixedly connected to the outside of the slider 2, and a gear 16 is fixedly connected to the top output end of the reduction motor 15, and the gear 16 and the gear ring seat 3 are meshed with each other. After the reduction motor 15 is driven to work, the gear 16 can be driven to rotate, and at this time, the gear ring seat 3 will also rotate under the drive of the gear 16, thereby realizing the steering of the feeder to adapt to the different feeding angles of the electric furnace. A support plate 4 is fixedly connected to the top of the gear ring seat 3, and a silo 6 is connected to the top of the support plate 4 through a shock-absorbing component. A vibration motor 19 is installed on the outside of the silo 6. The inner bottom surface of the silo 6 is inclined. When the vibration motor 19 is working, the material moves under the action of the inclined bottom surface. The vibration effect of the vibration motor 19 when working is reduced by the shock-absorbing component, thereby reducing the vibration damage to the bottom structure. The shock absorbing assembly includes a spring damping shock absorber 5, the top of the spring damping shock absorber 5 is rotatably connected to the outside of the silo 6, and the bottom of the spring damping shock absorber 5 is rotatably connected to the top of the support plate 4. The spring damping shock absorber 5 is an existing product and will not be described in detail here. A hopper 20 is fixedly connected to the top of the silo 6, and the hopper 20 is used to increase the size of the top opening of the silo 6, thereby facilitating the loading and processing of the silo 6.
[0035] Reference Figure 1-Figure 2, the outer side of the silo 6 is rotatably connected to a feeding chute 7, and the materials to be fed are moved from the feeding chute 7 to the electric furnace. The outer side of the silo 6 is also rotatably connected to an electric push rod 2 10, and the other end of the electric push rod 2 10 is rotatably connected to the outer side of the feeding chute 7. The angle between the feeding chute 7 and the silo 6 can be adjusted by driving the electric push rod 2 10. When feeding, the material feeding speed and the amount of material fed per unit time can be adjusted by adjusting the angle. A blocking component is installed at the free end of the feeding chute 7. The blocking component is used to block the free end of the feeding chute 7. Firstly, it can prevent the material from falling during the movement of the feeder, and secondly, the opening size of the free end can be adjusted to improve the uniformity of the vibration feeding, thereby avoiding the situation where the electric furnace mouth is blocked due to excessive feeding at a single time. The material blocking assembly includes a baffle plate 8, which is rotatably connected to the free end of the material discharge chute 7. The outer side of the material discharge chute 7 is rotatably connected to an electric push rod 9, and the other end of the electric push rod 9 is rotatably connected to the outer side of the baffle plate 8. By driving the electric push rod 9 to work, the baffle plate 8 can be driven to rotate along the edge of the material discharge chute 7, thereby changing the angle between the baffle plate 8 and the material discharge chute 7, thereby assisting the feeding of materials.
[0036] Reference Figure 2-Figure 3 , a notch 11 is provided at the end of the feeding chute 7, and the connecting shaft of the baffle plate 8 and the electric push rod 9 is located between the notches 11. When the electric push rod 9 is retracted, the connecting shaft of the baffle plate 8 enters the middle of the notch 11, and the baffle plate 8 is in a vertical state with the feeding chute 7, thereby ensuring effective shielding of the free end of the feeding chute 7. A baffle 13 is fixedly connected to the end of the feeding chute 7 away from the baffle plate 8, and a groove 12 is provided at the end of the silo 6 facing the feeding chute 7. The groove 12 and the baffle 13 abut against each other. After the angle of the feeding chute 7 and the silo 6 changes, a gap is formed between the silo 6 and the feeding chute 7. In order to prevent the material from falling from the gap, an arc-shaped baffle 13 is added to the outer side of the feeding chute 7, and a prefabricated adaptive groove 12 is provided on the inner side of the silo 6. When the feeding chute 7 rotates, the baffle 13 slides on the side wall of the groove 12, thereby blocking the gap to prevent the material from falling.
[0037] Working principle: first, store an appropriate amount of material inside the silo 6, and then use the moving component at the bottom of the base 1 to move the entire device to the position where feeding is required, and make the outlet end of the discharge chute 7 align with the entrance of the electric furnace, and then drive the electric push rod 9 to push the baffle plate 8 outward, thereby opening the outlet end of the discharge chute 7, and then start the vibration motor 19 to vibrate the silo 6. At this time, the material inside the silo 6 falls under the action of the inclined bottom of the silo 6 and the discharge chute 7, thus completing the discharge.
[0038] When there is a large difference in height between the furnace mouth and the discharge port of the discharge chute 7, in order to prevent materials from scattering around the furnace during the discharge process, the discharge chute 7 can be driven to rotate as a whole by driving the electric push rod 10 to adjust the position of the discharge port. At the same time, the baffle 13 slides on the inside of the groove 12 to block the gap between the discharge chute 7 and the silo 6 to prevent materials from falling from the gap.
[0039] When the feeder corresponds to multiple electric furnaces at one time, the gear 16 is driven to rotate by driving the reduction motor 15, thereby driving the gear ring seat 3 to rotate, so as to adjust the direction of the hopper 6 and the lower chute 7 to adapt to the feeding operation of the electric furnace mouth in different directions. When the distance between the lower chute 7 and the electric furnace mouth is large, the slider 2 can be pushed to move in the middle of the base 1 by driving the electric push rod 3 14, thereby pushing the support plate 4 and the entire hopper 6 toward the electric furnace mouth. In this way, it can better ensure that the material enters the furnace mouth, thereby increasing the feeding range of the equipment and making it more convenient to use.
[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
