Description

Technical Field

[0001] This utility model relates to the field of low-carbon manganese silicon alloy production technology, specifically an automatic uniform feeding device for low-carbon manganese silicon alloy production furnace materials. Background Technology

[0002] Silicon-manganese alloy is an alloy composed of manganese, silicon, iron, and small amounts of carbon and other elements. It is a widely used and produced ferroalloy. Silicon-manganese alloy is a reducing agent for low-carbon ferromanganese and metallic manganese in smelting. It is also used as a composite deoxidizer, alloying agent and desulfurizer in steelmaking. After the smelting enters the refining stage, tools are needed to push the unmelted furnace charge around the furnace wall to the furnace core and around the electrodes to promote the rapid melting of the furnace charge.

[0003] The announcement number is CN213327752U, which discloses "a furnace charge equalization device for producing low-carbon manganese silicon alloy, including a pusher and a support; wherein the pusher is mounted on the support and moves forward, backward and rotates with the support as the fulcrum; the pusher includes a shovel rod, a shovel head, and a sliding rod; the shovel head has a trapezoidal side section with the bottom surface larger than the top surface, a shovel rod is provided perpendicular to the shovel head at the rear center position, and sliding rods are provided on the left and right sides or the top and bottom sides of the shovel head connected to the shovel rod, the sliding rods and the shovel head forming a triangular structure; the support includes a vertical rod, a lower beam rod, and an upper beam rod; the vertical rod has two members, and the lower beam rod is horizontally fixedly connected between the vertical rods, and sliding grooves are provided symmetrically along the axial direction on the inner side of the vertical rods";

[0004] There are still some drawbacks in its use. The pusher is manually operated to move the pusher and push the accumulated material to distribute it evenly inside the electric arc furnace. However, when operating manually, because there are some openings at the top of the electric arc furnace, high-temperature molten metal will splash outwards when the electric arc is working. The high-temperature molten metal can easily burn the operator. In addition, the temperature around the electric arc furnace is high, and the manual strength is small, making it difficult to quickly push the unmelted furnace material at the inner edge of the electric arc furnace towards the electric arc. Utility Model Content

[0005] The purpose of this invention is to provide an automatic uniform feeding device for low-carbon manganese-silicon alloy production furnace materials, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An automatic uniform feeding device for low-carbon manganese-silicon alloy production furnace charge includes:

[0008] A fixing component, the fixing component including a fixing frame, a first through hole is opened at one end of the upper surface of the fixing frame, and a second through hole is opened at the other end of the upper surface of the fixing frame;

[0009] The first transmission component is movably disposed inside the second through hole. The first transmission component includes a bearing fixedly installed inside the first through hole and the second through hole. The inner ring of the bearing located inside the second through hole is fixedly installed with a first rotating shaft. The lower end of the first rotating shaft is fixedly installed with a first flange. The lower end of the first flange is detachably connected to a stirring plate.

[0010] The second transmission component is movably located inside the fixed frame.

[0011] Furthermore, a limiting plate is fixedly installed on the outer surface of the first rotating shaft.

[0012] Furthermore, a plurality of fixing rods are fixedly installed on the upper surface of the fixing frame, and a reinforcing frame fixedly connected to the fixing frame is fixedly installed between the plurality of fixing rods. A reinforcing plate is fixedly installed inside the fixing frame, and a sliding groove is provided on the lower surface of the fixing frame.

[0013] Preferably, the second transmission assembly includes:

[0014] The second rotating shaft is slidably connected inside the slide groove;

[0015] Flange No. 2 is fixedly installed at the lower end of shaft No. 2;

[0016] Push plate, detachably connected to the lower end of flange No. 2;

[0017] The turntable is fixedly connected to the inner ring of the bearing inside the first through hole.

[0018] Preferably, a second limiting plate is fixedly installed on the outer surface of the second rotating shaft, and a connecting rod is rotatably connected to the outer side of the second rotating shaft. One end of the connecting rod passes through the turntable and is rotatably connected to the turntable.

[0019] Preferably, a motor is fixedly mounted on the upper surface of the fixed frame by a bracket, the output end of the motor is fixedly connected to the turntable, and sprockets are fixedly mounted on the upper part of the outer surface of the turntable and the first rotating shaft, and a chain is connected to the outer meshing of the two sprockets.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1. Secure the fixing rod and top cover with fasteners to fix the fixing frame under the top cover. The motor runs and drives the turntable to rotate. Through the transmission of sprockets and chains, the turntable and the No. 1 rotating shaft rotate synchronously. The turntable drives the push plate to move back and forth. The No. 1 rotating shaft drives the stirring plate to rotate, stirring the unmelted furnace material while pushing the unmelted furnace material.

[0022] 2. When the turntable rotates, it drives the connecting rod to move, causing the No. 2 rotating shaft to slide inside the chute. This pushes the pusher plate to move back and forth, pushing the furnace charge stirred by the stirring plate to the vicinity of the electric arc. As the furnace body rotates, the stirring plate stirs the unmelted furnace charge at the edge of the furnace body. Under the action of the pusher plate, the pusher plate pushes the unmelted furnace charge to the vicinity of the electric arc, so that the furnace charge inside the furnace body is heated and melted evenly. This replaces the manual operation of the pusher to push the furnace charge, reducing the risk of injury to personnel from splashed high-temperature molten metal. At the same time, it pushes the unmelted furnace charge to the vicinity of the electric arc evenly and quickly. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figure 1-6 In this embodiment of the present invention, an automatic uniform feeding device for low-carbon manganese silicon alloy production furnace includes a fixing component 1, which includes a fixing frame 101. A first through hole 104 is opened at one end of the upper surface of the fixing frame 101, and a second through hole 105 is opened at the other end of the upper surface of the fixing frame 101. A first transmission component 2 is movably disposed inside the second through hole 105. The first transmission component 2 includes a bearing 201 fixedly installed inside the first through hole 104 and the second through hole 105. A first rotating shaft 202 is fixedly installed on the inner ring of the bearing 201 located inside the second through hole 105. A first flange 204 is fixedly installed on the lower end of the first rotating shaft 202. A stirring plate 205 is detachably connected to the lower end of the first flange 204. A second transmission component 3 is movably disposed inside the fixing frame 101.

[0032] Specifically, the stirring plate 205 and the pusher plate 304 are connected to the top cover of the electric arc furnace by the fixing component 1, so that they penetrate into the furnace body synchronously with the electric arc. When the furnace body rotates, the stirring plate 205 rotates and stirs the unmelted furnace material at the edge of the furnace body to the pusher plate 304. The pusher plate 304 moves and pushes this part of the furnace material to the vicinity of the electric arc.

[0033] Example 1

[0034] like Figure 6 As shown, in this embodiment, a plurality of fixing rods 102 are fixedly installed on the upper surface of the fixing frame 101, and a reinforcing frame 103 fixedly connected to the fixing frame 101 is fixedly installed between the plurality of fixing rods 102. A reinforcing plate 106 is fixedly installed inside the fixing frame 101, and a sliding groove 107 is provided on the lower surface of the fixing frame 101.

[0035] In this embodiment, the fixing rod 102 and the top cover are fastened with fasteners to fix the fixing frame 101 under the top cover. The reinforcement frame 103 increases the firmness between the multiple fixing rods 102, and the reinforcement plate 106 increases the firmness at one end opening of the fixing frame 101, thereby improving the overall stability of the fixing frame 101.

[0036] like Figure 1-5 As shown, in this embodiment, the second transmission assembly 3 includes: a second rotating shaft 301 slidably connected to the inside of the slide groove 107; a second flange 303 fixedly installed at the lower end of the second rotating shaft 301; a push plate 304 detachably connected to the lower end of the second flange 303; and a turntable 305 fixedly connected to the inner ring of the bearing 201 inside the first through hole 104. A second limiting plate 302 is fixedly installed on the outer surface of the second rotating shaft 301, and a connecting rod 306 is rotatably connected to the outer side of the second rotating shaft 301. One end of the connecting rod 306 passes through the turntable 305 and is rotatably connected to the turntable 305.

[0037] In practice, when the turntable 305 rotates, it drives the connecting rod 306 to move, causing one end of the connecting rod 306 to rotate inside the turntable 305 and the other end to rotate around the second rotating shaft 301. This causes the second rotating shaft 301 to slide inside the slide groove 107, pushing the push plate 304 to move back and forth. This pushes the furnace charge stirred by the stirring plate 205 to the vicinity of the electric arc. Thus, when the furnace body rotates, the stirring plate 205 stirs the unmelted furnace charge at the edge of the furnace body. Under the action of the push plate 304, the push plate 304 pushes the unmelted furnace charge to the vicinity of the electric arc, so that the furnace charge inside the furnace body is heated and melted evenly. This replaces the manual operation of the pusher to push the furnace charge, reducing the risk of injury to personnel from the splashed high-temperature molten metal. At the same time, it pushes the unmelted furnace charge evenly and quickly to the vicinity of the electric arc.

[0038] like Figure 3-5 As shown, in this embodiment, a motor 307 is fixedly installed on the upper surface of the fixed frame 101 by a bracket. The output end of the motor 307 is fixedly connected to the turntable 305. A sprocket 308 is fixedly installed on the upper part of the outer surface of the turntable 305 and the first rotating shaft 202. A chain 309 is connected to the outer meshing of the two sprockets 308.

[0039] In practice, the motor 307 operates, driving the turntable 305 to rotate. Through the transmission of the sprocket 308 and the chain 309, the turntable 305 and the first rotating shaft 202 rotate synchronously. The turntable 305 drives the push plate 304 to move back and forth, and the first rotating shaft 202 drives the stirring plate 205 to rotate, stirring the unmelted furnace charge while pushing the unmelted furnace charge towards the electric arc.

[0040] Example 2

[0041] Based on Embodiment 1, in order to compensate for the problem of the large vertical tensile force on the bearing 201.

[0042] like Figure 3 and Figure 5 As shown, in this embodiment, a limiting plate 203 is fixedly installed on the outer surface of the first rotating shaft 202.

[0043] In practice, the first limiting plate 203 is attached to the surface of the fixed frame 101 to reduce the vertical tension of the mixing plate 205 on the bearing 201 and improve the service life of the bearing 201.

[0044] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
