[0001] The utility model relates to the technical field of steelmaking, and particularly relates to a steelmaking alloy feeding system. Background Art

[0002] Alloys play an important role in steelmaking production. Different types of alloys can have different degrees of influence on the quality of steel. For example, adding elements such as molybdenum, vanadium, and niobium can improve the mechanical strength, plasticity, thermal stability, and corrosion resistance of steel; adding nickel can improve the corrosion resistance, high-temperature strength, and toughness of steel; adding chromium can improve the hardness, corrosion resistance, and heat resistance of steel. The addition of alloys can make steelmaking products meet the requirements of different industries for material properties.

[0003] At present, some workshops use the method of simultaneous melting and processing of multiple electric furnaces for steelmaking. Commonly, two small electric furnaces are used for simultaneous melting production. At this time, the traditional method of manually adding alloys is a bit stretched. The labor intensity of workers is high, and errors in quantity or type are likely to occur during the addition process. In view of this, the utility model provides an alloy feeding system for multiple electric furnace steelmaking. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a steelmaking alloy feeding system that can facilitate the addition of alloys into the melting furnace during steelmaking with multiple melting furnaces.

The feeding mechanism receives the material discharged from the corresponding outlet pipe and adds it into the melting furnace.

[0006] The batching hopper can be used to achieve the batching of alloys. When adding alloys, the material in the batching hopper enters the distributing chute, is introduced into the designated feeding mechanism through the distributing chute, and then the feeding mechanism transports and adds the received material into the melting furnace to achieve the addition of alloys.

When the material distribution baffle is in the second outlet pipe blocking position, the material distribution baffle blocks the second outlet pipe and the plate surface of the material distribution baffle is parallel to the axis of the first outlet pipe.

[0012] As an alternative solution of the present utility model, the discharge control member is arranged at the connection of the batching hopper and the inlet pipe.

The feeding conveyor is arranged on the feeding frame. The leading end of the transportation of the feeding conveyor is arranged below the outlet pipe. The rotary driving member drives the feeding frame to rotate between the feeding position and the standby position. When feeding the melting furnace, the feeding frame drives the trailing end of the transportation of the feeding conveyor to be at the feeding port of the melting furnace. When not feeding the melting furnace, the feeding frame drives the trailing end of the transportation of the feeding conveyor to leave the feeding port of the melting furnace, avoiding the flame emitted from the feeding port of the melting furnace from burning the equipment.

[0015] As an alternative solution of the present utility model, a blanking port is provided at the conveying end of the feeding conveyor on the feeding rack, and when the feeding rack rotates to the feeding position, the blanking port corresponds to the feeding port of the smelting furnace.

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] As Figures 1 - 3 shown, this embodiment provides a steelmaking alloy feeding system to facilitate the problem of inconvenient alloy feeding when multiple electric furnaces or multiple smelting furnaces are smelted simultaneously. The steelmaking alloy feeding system includes a batching mechanism 1, a material distributing mechanism 2 and a feeding mechanism 3. The batching mechanism 1 includes a batching hopper 11, a weighing sensor 12 and a discharge control part 13. The batching hopper 11 is arranged on the batching table and connected to the batching table through the weighing sensor 12. A discharge control part 13 is arranged at the discharge end of the batching hopper 11; the material distributing mechanism 2 includes a material distribution chute. The material distribution chute includes an inlet pipe 21 and at least one outlet pipe 22. The top end of the inlet pipe 21 is communicated with the discharge end of the batching hopper 11. The bottom end of the inlet pipe 21 is communicated with the top ends of the respective outlet pipes 22. A feeding mechanism 3 is arranged at the bottom end of each outlet pipe 22. The feeding mechanism 3 receives the material discharged from the corresponding outlet pipe 22 and adds it to the smelting furnace.

[0026] Specifically, a discharge control part 13 is arranged at the discharge end of the batching hopper 11. The discharge control part 13 is used to adjust the opening and closing state of the discharge end of the batching hopper 11. The batching hopper 11 is arranged on the weighing platform and connected to the weighing platform through the weighing sensor 12. When the discharge control part 13 closes the discharge end of the batching hopper 11, the batching hopper 11 can store materials. At this time, the amount of materials stored in the batching hopper 11 can be measured through the weighing sensor 12. When a certain amount of materials is weighed in the batching hopper 11, the discharge control part 13 controls the discharge end of the batching hopper 11 to open, and the materials in the batching hopper 11 can be discharged from the discharge end.

[0027] The material distributing chute pipe includes an inlet pipe 21 and at least one outlet pipe 22. The top ends of the respective outlet pipes 22 are communicated with the bottom end of the inlet pipe 21. The top end of the inlet pipe 21 is communicated with the discharge end of the batching hopper 11. When the material in the batching hopper 11 is discharged from the discharge end, it enters the inlet pipe 21 and is then discharged through the outlet pipe 22 to a specified position. A feeding device is provided at the bottom end of each outlet pipe 22. After the material in the batching hopper 11 reaches the feeding device at the specified position through the material distributing chute pipe, the feeding device transfers the received material into the smelting furnace.

[0028] The steelmaking alloy feeding system of this embodiment is applicable to single-smelting-furnace steelmaking or multi-smelting-furnace steelmaking, especially applicable to multi-smelting-furnace steelmaking. The steelmaking alloy feeding system is arranged between the respective smelting furnaces. The weighing sensor 12 is used to add a specified weight of alloy into the batching hopper 11. When it is necessary to add alloy into the smelting furnace, the discharge control member 13 opens the discharge end of the batching hopper 11. The alloy in the counterweight hopper enters the material distributing chute pipe and enters the feeding mechanism 3 corresponding to the specified smelting furnace along the material distributing chute pipe. The feeding mechanism 3 transfers the received alloy to the feeding port of the smelting furnace, realizing the feeding of the smelting furnace.

[0029] In some embodiments, in order to facilitate batching into the batching hopper, at least one raw material feeding mechanism 4 is provided above the batching table. The discharge ends of the respective raw material feeding mechanisms 4 are arranged at the batching hopper 11 and feed the batching hopper 11. The raw material feeding mechanism 4 is used to feed the batching hopper 11. Since generally multiple types of alloys are required for steelmaking, the raw material feeding mechanism 4 is preferably multiple. Different types of alloys are respectively placed in different raw material feeding mechanisms 4. When preparing to add alloy into the smelting furnace, the raw material feeding mechanism 4 containing one type of alloy feeds the batching hopper 11. According to the weighing sensor 12, the addition amount of this alloy is obtained. When the required amount is reached, this raw material feeding mechanism 4 stops feeding the batching hopper 11. The raw material mechanism containing another type of alloy feeds the batching hopper 11. Finally, the batching hopper 11 stores multiple types of alloys required to be added to the smelting furnace. When it is time to add to the smelting furnace, the discharge control member 13 controls the mixture in the batching hopper 11 to enter the distributing mechanism 2 and is added to the specified smelting furnace through the distributing mechanism 2 and the feeding mechanism 3.

[0030] Please refer to Figures 1 - 3 , since most of the small smelting furnaces on the market are used in pairs at present. As a preferred embodiment, the steelmaking alloy feeding system is arranged between two smelting furnaces, and there are two outlet pipes 22 of the material distributing chute pipe. For the convenience of description, these two outlet pipes 22 are respectively referred to as the first outlet pipe 22 and the second outlet pipe 22.

[0031] A material distribution control member 23 is provided in the material distribution chute. The material distribution control member 23 includes a material distribution rotating shaft, a material distribution baffle, and a material distribution driving member. The material distribution rotating shaft is provided in the material distribution chute and is rotatably connected to the material distribution chute. The material distribution rotating shaft is located at the connection of the first outlet pipe 22, the second outlet pipe 22, and the inlet pipe 21. A material distribution baffle is provided on the material distribution rotating shaft in the material distribution chute. The material distribution driving member is provided on the material distribution chute, and the power output end of the material distribution driving member is connected to the material distribution rotating shaft. The material distribution driving member drives the material distribution baffle to move between the blocking position of the first outlet pipe 22 and the blocking position of the second outlet pipe 22 by driving the material distribution rotating shaft to rotate.

[0032] Specifically, to enable the material in the batching hopper 11 to be supplied to the designated smelting furnace through the material distribution chute, a material distribution control member 23 is provided in the material distribution chute. The material in the batching hopper 11 enters the inlet pipe 21 and enters the first outlet pipe 22 and / or the second outlet pipe 22 under the control of the material distribution control member 23.

[0033] The material distribution control member 23 includes a material distribution rotating shaft, a material distribution baffle, and a material distribution driving member. The material distribution rotating shaft is provided in the material distribution chute, and the material distribution rotating shaft and the material distribution chute are rotatably connected through installation components such as bearings. The material distribution rotating shaft is located at the connection of the first outlet pipe 22, the second outlet pipe 22, and the inlet pipe 21. A material distribution baffle is provided on the material distribution rotating shaft, and the material distribution baffle is located inside the material distribution chute. The rotation of the material distribution rotating shaft can drive the material distribution baffle to move.

[0034] One end of the material distribution rotating shaft extends outside the material distribution chute. The material distribution driving member is provided outside the material distribution chute. The material distribution driving member drives the material distribution baffle to move between the blocking position of the first outlet pipe 22 and the blocking position of the second outlet pipe 22 by driving the material distribution rotating shaft to rotate. When the material distribution baffle is at the blocking position of the first outlet pipe 22, the material distribution baffle is located at the pipe orifice of the first outlet pipe 22 and blocks the first outlet pipe 22. At this time, the material in the inlet pipe 21 is blocked and guided by the material distribution baffle and all enters the second outlet pipe 22, that is, the material in the batching hopper 11 is all supplied to the smelting furnace corresponding to the second outlet pipe 22. When the material distribution baffle is at the blocking position of the second outlet pipe 22, the material distribution baffle is located at the pipe orifice of the second outlet pipe 22 and blocks the second outlet pipe 22. At this time, the material in the inlet pipe 21 is blocked and guided by the material distribution baffle and all enters the first outlet pipe 22, that is, the material in the batching hopper 11 is all supplied to the smelting furnace corresponding to the first outlet pipe 22.

[0035] In some embodiments, the material distribution baffle can also move to the middle position between the blocking position of the first outlet pipe 22 and the blocking position of the second outlet pipe 22, so that the material is evenly distributed to the first outlet pipe 22 and the second outlet pipe 22, realizing synchronous feeding to the two smelting furnaces.

[0036] The material distribution driving member is a rotary motor or a linear motor. When the material distribution driving member is a linear motor, one end of the material distribution rotating shaft extends out of the material distribution chute and is provided with a swing arm. The action end of the material distribution driving member is hinged to the swing arm, and the material distribution driving member drives the material distribution rotating shaft to rotate through the swing arm. When the material distribution driving member is a rotary motor, the action end of the material distribution driving member is connected to the material distribution rotating shaft and directly drives the material distribution rotating shaft to rotate.

[0037] As a further embodiment, please refer to Figure 1 , both the first outlet pipe 22 and the second outlet pipe 22 are inclined. When the material distribution baffle is in the blocking position of the first outlet pipe 22, the material distribution baffle blocks the first outlet pipe 22 and the plate surface of the material distribution baffle is parallel to the axis of the second outlet pipe 22. When the material distribution baffle is in the blocking position of the second outlet pipe 22, the material distribution baffle blocks the second outlet pipe 22 and the plate surface of the material distribution baffle is parallel to the axis of the first outlet pipe 22.

[0038] Specifically, the bottoms of both the first outlet pipe 22 and the second outlet pipe 22 are higher than the melting furnace. The inlet pipe 21 and the two outlet pipes 22 form an inverted Y shape. When the material distribution baffle is in the blocking position of the first outlet pipe 22, the material distribution baffle blocks the first outlet pipe 22, and at the same time, the plate surface of the material distribution baffle is parallel to the axis of the second outlet pipe 22. At this time, in addition to blocking the pipe orifice of the first outlet pipe 22, the material distribution baffle can also play a role in guiding the alloy into the second outlet pipe 22. Similarly, when the material distribution baffle is in the blocking position of the second outlet pipe 22, the material distribution baffle blocks the second outlet pipe 22, and the plate surface of the material distribution baffle is parallel to the axis of the first outlet pipe 22 to introduce all the alloy into the first outlet pipe 22.

[0039] The discharge control member 13 is arranged at the connection between the batching hopper 11 and the inlet pipe 21. The discharge control member 13 includes a flap valve and a discharge driving member. The discharge driving member is arranged on the batching hopper. The power output end of the discharge driving member is connected to the gate plate of the flap valve and drives the gate plate to move between the batching discharge position and the batching preparation position.

[0040] Specifically, the discharge control member 13 includes a flap valve and a discharge driving member. The flap valve is installed at the discharge end of the batching hopper 11 and is also at the top of the inlet pipe 21. The discharge driving member is arranged outside the batching hopper. The discharge driving member is a power component such as a motor or a telescopic cylinder. The action end of the discharge driving member is connected to the connecting part of the flap valve. The discharge driving member drives the gate plate of the flap valve to move between the batching discharge position and the batching preparation position. When the gate plate of the discharge valve is in the batching preparation position, the gate plate closes the valve orifice of the discharge valve, that is, the discharge valve blocks the discharge end of the batching hopper 11. At this time, batching and storing materials can be carried out in the batching hopper 11. When the gate plate of the discharge valve is in the batching discharge position, the gate plate opens the valve orifice of the discharge valve. At this time, the discharge valve opens the discharge end of the batching hopper 11, and the materials in the batching hopper 11 can enter the material distribution chute.

[0041] As a preferred embodiment, the feeding mechanism 3 is a rotary feeding mechanism 3 .

[0042] As a specific example of the rotary feeding mechanism 3, see Figures 1 - 3 The feeding mechanism 3 includes a feeding base 31, a feeding frame 32, a rotating driving member 33 and a feeding conveyor 34. The feeding frame 32 is installed on the feeding base 31 and rotates relative to the feeding base 31. The rotating driving member 33 is arranged on the feeding base 31. The power output end of the rotating driving member 33 is connected to the feeding frame 32 and drives the feeding frame 32 to rotate between the feeding position and the standby position. The feeding conveyor 34 is arranged on the feeding frame 32, and the conveying head end of the feeding conveyor 34 is arranged below the outlet pipe 22.

[0043] Specifically, the feeding mechanism 3 includes a feeding base 31, a feeding frame 32, a rotating drive member 33 and a feeding conveyor 34. The feeding base 31 is arranged below the batching hopper 11, and the feeding frame 32 is arranged on the feeding base 31. The feeding base 31 and the feeding frame 32 are connected by a bearing structure. The feeding frame 32 can rotate relative to the feeding base 31. The rotating drive member 33 is a rotating drive motor. The power output end of the rotating drive member 33 is in transmission cooperation with the feeding frame 32. The rotating drive member 33 can drive the feeding frame 32 to rotate. The rotating drive member 33 drives the feeding frame 32 between the feeding position and the waiting position. The feeding conveyor 34 rotates between the machine positions; the feeding conveyor 34 is arranged on the feeding rack 32, and the conveying head end of the feeding conveyor 34 is always at the bottom end of the corresponding material distribution chute during the rotation of the feeding rack 32. When the feeding rack 32 is in the feeding position, the conveying end of the feeding conveyor 34 is at the feeding port of the smelting furnace, and the feeding conveyor 34 transfers the material received from the distribution chute to the feeding port of the smelting furnace and adds it into the smelting furnace. When the feeding rack 32 is in the standby position, the conveying ends of the feeding rack 32 and the feeding conveyor 34 are staggered from the feeding port of the smelting furnace to avoid the flame from the feeding port of the smelting furnace from burning the equipment.

[0044] The feeding conveyor 34 is preferably a vibrating conveyor.

[0045] As a further embodiment, in order to facilitate the feeding conveyor 34 to add materials to the smelting furnace, a feeding port is provided on the feeding rack 32 at the conveying end of the feeding conveyor 34. When the feeding rack 32 is turned to the feeding position, the feeding port corresponds to the feeding port of the smelting furnace.

[0046] In some embodiments, the raw material feeding mechanism 4 includes a raw material hopper 41 and a raw material conveyor 42. The raw material hopper 41 is arranged above the batching table, and the raw material conveyor 42 is arranged at the discharge end of the raw material hopper 41 and transports the raw materials in the raw material hopper 41 to the batching hopper 11.

[0047] Specifically, the raw material hopper 41 is arranged above the batching table, and the raw material conveyor 42 is arranged at the discharge end of the raw material hopper 41. The conveying head end of the raw material conveyor 42 is located below the discharge end of the raw material hopper 41, and the conveying tail end of the raw material conveyor 42 is located above the batching hopper 11. The raw material conveyor 42 adds the materials in the raw material hopper 41 into the batching hopper 11.

[0048] The raw material conveyor 42 is preferably a vibrating conveyor. When raw materials need to be added into the batching hopper 11, the raw material conveyor 42 works to drive the materials on its conveying surface to be transported to the batching hopper 11. As the raw material conveyor 42 works, the materials in the raw material hopper 41 are continuously exposed under the action of gravity. When the raw material conveyor 42 stops feeding, due to the large amount of materials accumulated in the raw material conveyor 42 blocking the discharge end of the raw material hopper 41, the materials in the raw material hopper 41 cannot continue to be discharged.

[0049] In some embodiments, the steelmaking alloy feeding system of this embodiment further includes a control system, which is a PLC control system or other control systems used in industrial production. The weighing sensor 12, the discharge driving part of the discharge control part 13, the distribution driving part of the distribution control part 23, the rotation driving part 33 of the feeding mechanism 3, the feeding conveyor 34, and the raw material conveyors 42 of each raw material feeder are all connected to the control system, and the automatic addition of alloy to the melting furnace is realized under the comprehensive control of the control system.
