[0002] Carbon ferrochrome, as an alloying agent for high-carbon ball bearing steel, tool steel, and high-speed steel, can improve the hardenability, wear resistance, and hardness of steel.

Figure 3 for Figure 1 The enlarged schematic diagram of part A shown below; Figure 4 for Figure 2 The enlarged schematic diagram of part B is shown. A lifting device for smelting low-carbon ferrochrome alloys includes: a main body 1, the main body 1 including a conveying box 11, a lifting mechanism 2 disposed inside the conveying box 11, the lifting mechanism 2 including a material conveying component 22, the material conveying component 22 being used for conveying materials;

[0031] A sealing mechanism 3, comprising a sealing plate 31, wherein the sealing plate 31 is installed inside the main body mechanism 1;

[0032] The first transmission mechanism 4 includes a movable plate 41, which is connected to the inside of the top of the conveyor box 11.

[0033] The second transmission mechanism 5 includes an elastic element 52, which is connected to the outer surface of the conveyor box 11.

[0034] The main body mechanism 1 supports the entire device and provides a conveying space. Multiple support legs are connected to the surface of the conveying box 11, which support and fix the conveying box 11. The lifting mechanism 2 lifts and conveys the material. The conveying component 22 can be a material plate or a hopper, preferably a hopper. When the conveying component 22 passes the bottom of the conveying box 11, the material inside the conveying box 11 can be introduced into the conveying component 22. Thus, the material can be conveyed by the movement of the conveying component 22. The sealing mechanism 3 seals the discharge hopper 13 to prevent dust from flowing out. The first transmission mechanism 4 connects and drives the conveying component 21. The top of the moving plate 41 is inclined. When the conveying component 21 rotates to the top and rotates downward, the conveying component 21 connects with the inclined surface of the moving plate 41, giving the moving plate 41 an outward push. The second transmission mechanism 5 connects and drives the sealing plate 31 to rotate.

[0035] The conveying box 11 is connected to a feed hopper 12 near the bottom and a discharge hopper 13 near the top. The sealing plate 31 is movably installed inside the discharge hopper 13.

[0036] The conveyor box 11 has an opening at the left end near the bottom. The feed hopper 12 is cone-shaped and is fixedly connected to the outer surface of the conveyor box 11 at the opening. The feed hopper 12 can be used to guide materials into the interior of the conveyor box 11. The discharge hopper 13 is connected to the right end of the conveyor box 11 near the top.

[0037] The conveying box 11 is internally connected to a conveying component 21, which is used to drive the material conveying component 22 to move. The material conveying component 22 is connected to the surface of the conveying component 21.

[0038] The conveying component 21 can be driven by a belt or a gear belt, preferably a gear belt. It consists of two gears meshing on their outer surfaces and a gear belt. A motor is connected to the surface of one of the gears. The material conveying component 22 is arrayed and connected to the surface of the gear belt. The motor drives the gear to rotate, and the gear belt meshes with the gear to drive the material conveying component 22 to rotate. When the material conveying component 22 rotates to the top, the material outlet gradually tilts downward, and the material flows out from the material outlet into the discharge hopper 13 by gravity.

[0039] The surface of the sealing plate 31 is connected to a push-pull rod 32, one end of the moving plate 41 is connected to a first connecting frame 42, both ends of the first connecting frame 42 are connected to a transmission rod 53, and the other end of the push-pull rod 32 is connected to a second connecting frame 51.

[0040] One end of the push-pull rod 32 is rotatably connected to the surface of the push-pull rod 32 near the bottom. The surface of the discharge hopper 13 is provided with a groove, and a slider is slidably embedded inside the groove. The other end of the push-pull rod 32 is rotatably connected to the surface of the slider. The slider drives the other end of the push-pull rod 32 to move upward. One end can pull the bottom of the sealing plate 31 to rotate, so that the discharge hopper 13 is opened and the material falling into the discharge hopper 13 flows out along the surface of the discharge hopper 13. The first connecting frame 42 is U-shaped and is fixedly connected to one end of the moving plate 41 embedded on the outside, and both ends are on the front and rear outer surfaces of the conveyor box 11.

[0041] The two ends of the second connecting frame 51 are connected to the surface of the elastic member 52, and the other end of the transmission rod 53 is connected to the two ends of the second connecting frame 51.

[0042] The second connecting frame 51 is connected to the surface of the connecting block at the other end of the push-pull rod 32. The elastic element 52 can be a spring telescopic rod or a spring slide rod, preferably a spring slide rod. There are two spring slide rods. The two slide rods are fixedly connected to the front and rear outer surfaces of the main body mechanism 1. The two ends of the second connecting frame 51 are slidably connected to the surfaces of the two slide rods. One end of the two transmission rods 53 is rotatably connected to the two ends of the first connecting frame 42, and the other end is rotatably connected to the two ends of the second connecting frame 51.

[0043] The working principle of the lifting device for smelting low-carbon ferrochrome alloys provided by this utility model is as follows:

[0044] Material is poured from the feed hopper 12 into the conveyor box 11. The conveying component 21 is activated to drive the conveyor component 22 to rotate. When the conveyor component 22 rotates to the bottom of the conveyor box 11, the material can be guided into the conveyor component 22 and then move upward and then downward. At this time, the conveyor component 22 is connected to the moving plate 41 and gives the moving plate 41 an outward push force. The two ends of the first connecting frame 42 drive the two transmission rods 53 to move. At the same time, the angle of the transmission rods 53 changes, and the other end pulls the second connecting frame 51, causing one end of the push-pull rod 32 to move upward. Through the sealing plate 31 and the discharge hopper The connection limit of 13, the other end of the push-pull rod 32 applies a pulling force to the sealing plate 31, pulling the sealing plate 31 to rotate, the discharge hopper 13 opens inward, and the material inside the conveying component 22 flows out through the discharge hopper 13 until the conveying component 21 is no longer connected to the moving plate 41. Under the elastic force of the elastic component 52, the second connecting frame 51 drives one end of the push-pull rod 32 and the other end of the transmission rod 53 to move downward. The push-pull rod 32 then pushes the sealing plate 31 to rotate and seal the discharge hopper 13. The transmission rod 53 then pulls the first connecting frame 42 to drive the moving plate 41 to move inward. This cycle is repeated to realize the material conveying.

[0045] Compared with related technologies, the lifting device for smelting low-carbon ferrochrome alloys provided by this utility model has the following beneficial effects:

[0046] This utility model provides a lifting device for smelting low-carbon ferrochrome alloys. The lifting mechanism 2 can transport materials while the material conveying component 22 is connected to the moving plate 41 and driven by the second transmission mechanism 5, which can rotate the sealing plate 31 to allow the material to flow in and reset the seal, effectively reducing the dust flying during the conveying process of the lifting mechanism 2.

The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0049] Specifically, the difference in the lifting device for smelting low-carbon ferrochrome alloy provided in the second embodiment of this application is that the surface of the conveying box 11 of the lifting device for smelting low-carbon ferrochrome alloy is provided with a heat dissipation mechanism 6, the heat dissipation mechanism 6 includes a heat dissipation fan 61, the heat dissipation fan 61 is installed on the outer surface of the conveying box 11, and heat dissipation holes 62 are opened on the inner surface of the main body 1.

[0050] There are two cooling fans 61, which are respectively connected to the surfaces of two gears in the transmission component 21. The inner surface of the main body 1 is ring-shaped, dividing the interior of the main body 1 into a sealed space. The heat dissipation holes 62 are arrayed on the ring surface. The gears drive the fan blades of the two cooling fans 61 to rotate, pushing the airflow into the sealed space. After flowing through the heat dissipation holes 62, the air enters the inner ring and flows on the surface of the transmission component 21 to absorb the heat on the surface of the transmission component 21. The air then flows out through the heat dissipation holes 62.

[0051] The working principle of the lifting device for smelting low-carbon ferrochrome alloys provided by this utility model is as follows:

[0052] When the conveying component 21 is working, its internal gear drives the fan blades in the cooling fan 61 to rotate, pushing air into the interior of the main body 1. After entering the interior of the main body 1, the air passes through the heat dissipation hole 62 and then passes over the surface of the conveying component 21, absorbing the heat from the surface of the conveying component 21 before being dissipated through the heat dissipation hole 62.

[0054] This utility model provides a lifting device for smelting low-carbon ferrochrome alloys. After the cooling fan 61 blows air into the conveyor box 11, the air can flow through the heat dissipation holes 62 to the surface of the conveying component 21 and absorb heat, thereby improving the heat dissipation performance of the conveying component 21.
