Description

Technical Field

[0001] The utility model relates to the technical field of steelmaking, in particular to a chain-controlled pressure roller. Background Art

[0002] Sintering refers to the process of transforming powdered materials into dense bodies, usually carried out at high temperatures, so that solid particles are mutually bonded, grains grow, and voids are reduced, ultimately forming a dense polycrystalline sintered body with a specific microstructure.

[0003] During sintering of ore, in order to improve the air permeability of the sintered material and reduce air leakage, and to increase the output and quality of the sintered ore, the method of flattening the material surface is usually adopted to improve the uniformity and flatness of the ore before sintering.

[0004] Before sintering, the existing ore is usually leveled with a scraper leveler. During production and observation, it was found that the cut material accumulated at the front end of the scraper tends to compact the material layer. Excessive compactness of the material layer will lead to poor permeability of the sintering material layer, which will in turn reduce the sintering quality of the ore.

When the connecting wheel 105 moves, it will contact the first chain 106 and rotate under the action of friction, so that the height of the first chain 106 changes. At this time, the first chain 106 will move with the roller 107 until the roller 107 moves to a suitable height. When the ore passes through the roller 107, it will be squeezed by the roller 107, so that the device can control the height of the ore; the connecting wheel 105 will move with the support plate 104, so that the height of the first chain 106 and the roller 107 will change, so that the device can adjust the height of the roller 107, improve the convenience and accuracy of the device in controlling the thickness and density of the ore, and optimize the air permeability of the ore during sintering.

When the elastic rod 4 moves, it will come into contact with the transport component 108 and be squeezed by it. After the elastic rod 4 is subjected to pressure, it will bend and cause the slide plate 42 to slide along the air hole 33, and then the slide plate 42 will detach from the air hole 33 and leave the air hole 33 in an open state. Because the total air flow in the cam 23 remains unchanged, the remaining air holes 33 will be closed by the slide plate 42, and the air flow at the open air hole 33 will be larger at this time, thereby enhancing the impact of the air flow on the transport component 108.

[0031] Reference Figure 3As shown, a plurality of vertical poles 5 are fixedly connected to the middle of the roller 107; the vertical poles 5 are arranged in an array; when the ore reaches the roller 107, it will come into contact with the vertical poles 5, and the vertical poles 5 will divide the ore, so that the high-density areas in the ore are broken up, further improving the looseness of the ore before sintering and enhancing the air permeability inside the ore.

[0032] Reference Figure 3 As shown, a pair of orifice plates 6 are fixedly connected to the middle of the vertical pole 5; the adjacent orifice plates 6 are symmetrically arranged; when the mineral material passes through the vertical pole 5, it will also come into contact with the orifice plate 6, and the holes on the surface of the orifice plate 6 will filter the mineral material, so that the block mineral material in the mineral material is crushed, thereby enhancing the cutting effect of the vertical pole 5 on the mineral material.

[0033] Reference Figure 6 As shown, an oil storage box 7 is fixedly connected to the middle part of the frame 1; the middle part of the oil storage box 7 is rotatably connected to a rotating wheel 72; when the first chain 106 moves, it will come into contact with the rotating wheel 72 and cause the rotating wheel 72 to rotate under the action of friction. Because lubricating oil is injected into the interior of the oil storage box 7, the rotating wheel 72 will dip into the lubricating oil inside the oil storage box 7 when it rotates, and then the rotating wheel 72 will brush the lubricating oil on the surface to the surface of the first chain 106, thereby realizing lubrication of the first chain 106 by the device and reducing the wear of the first chain 106 due to friction when the first chain 106 moves.

[0035] Working principle: the staff can start the electric push rod 103 so that the electric push rod 103 drives the support plate 104 to move. When the support plate 104 moves, it will move with the connecting wheel 105. When the connecting wheel 105 moves, it will contact the first chain 106 and rotate under the action of friction, so that the height of the first chain 106 changes. At this time, the first chain 106 will move with the roller 107 until the roller 107 moves to a suitable height. When the ore passes through the roller 107, it will be squeezed by the roller 107, so that the device can control the height of the ore. When the device is started, the motor 2 will also start, and the motor 2 will rotate the shaft 22. When the shaft 22 rotates, it will The cam 23 rotates together with the cam 23. When the cam 23 rotates, the raised area on the surface of the cam 23 will come into contact with the transport component 108 and squeeze the transport component 108. At this time, the mineral materials on the surface of the transport component 108 will be dispersed under the squeezing action, and then the dispersed mineral materials will pass through the roller 107 and be flattened by the roller 107; after the staff connects the air intake pipe 32 to the air pump, the air pump will fill air into the air intake pipe 32, and the air flow will pass through the air intake pipe 32 into the connecting plate 3 and the interior of the rotating shaft 22, and then the air flow will enter the interior of the cam 23 and be ejected from the air hole 33. The transport component 108 will be impacted by the air flow, causing its surface to bulge, thereby causing the transport component 108 to The mineral material on the surface of the component 108 is subjected to an additional force; when the cam 23 rotates, it will also drive the elastic rod 4 and the slide plate 42 to move together. When the elastic rod 4 moves, it will come into contact with the transport component 108 and be squeezed by it. After the elastic rod 4 is subjected to the pressure, it will bend and make the slide plate 42 slide along the air hole 33. Then the slide plate 42 will separate from the air hole 33 and make the air hole 33 open. Because the total air flow in the cam 23 remains unchanged, the remaining air holes 33 will be closed by the slide plate 42. At this time, the air flow at the open air hole 33 will be larger; when the mineral material reaches the roller 107, it will come into contact with the vertical rod 5, and the vertical rod 5 will divide the mineral material, making the mineral material dense. The areas with high degree of crushing are broken; when the mineral material passes through the vertical pole 5, it will also come into contact with the orifice plate 6. The holes on the surface of the orifice plate 6 will filter the mineral material, so that the block mineral material in the mineral material is crushed; when the first chain 106 moves, it will come into contact with the rotating wheel 72 and make the rotating wheel 72 rotate under the action of friction. Because the interior of the oil storage box 7 is injected with lubricating oil, the rotating wheel 72 will dip into the lubricating oil inside the oil storage box 7 when it rotates, and then the rotating wheel 72 will brush the surface lubricating oil to the surface of the first chain 106; when the rotating wheel 72 brushes the lubricating oil to the first chain 106, some of the lubricating oil will splash, and these lubricating oils will drip into the interior of the collecting box 8 and be collected by the collecting box 8.
