Description

Technical Field

[0001] The present application relates to the technical field of ore conveying, and in particular to a bottom blowing furnace feeding and preventing material interruption device. Background Art

[0002] During the smelting process of the bottom-blown furnace, it is necessary to ensure the stable transportation of the ore. The process is: the ore to be smelted is poured into the hopper, and the ore slides onto the ore conveyor under the influence of gravity. The ore is transported to the bottom-blown furnace for smelting through the ore conveyor.

[0003] In the actual production process, as the ore accumulates in the hopper, the ore at the bottom of the hopper is easily agglomerated under the action of pressure, causing blockage at the hopper outlet, resulting in the inability to discharge the ore normally, thus affecting the normal smelting of the bottom-blown furnace.

[0004] At present, in order to ensure the normal discharge of the hopper, a vibration motor is installed on the outer wall of the hopper. When the hopper discharges abnormally, workers need to manually start the vibration motor to dredge the hopper through the vibration motor. This method requires workers to be on duty next to the hopper for a long time, which is labor-intensive. In addition, manual detection is prone to errors, resulting in workers being unable to detect abnormal discharge in the first place, thus affecting the normal progress of smelting. Utility Model Content

[0005] In order to solve or partially solve the problems existing in the related technology, the present application provides a bottom blowing furnace feeding anti-breakage device, which can detect whether the ore conveying is normal. When the ore conveying is abnormal, it can automatically start the vibration motor to clear the hopper, thereby ensuring the stability of the feeding.

[0006] The present application provides a bottom blowing furnace feed interruption prevention device, comprising a bracket, a hook, an adjusting rod, a mounting plate, a detection piece, and a controller. The adjusting rod is slidably connected to a hook, and the adjusting rod is fixedly connected to the bracket through the hook. The bracket is fixedly installed on a mineral conveyor. The bottom of the adjusting rod is fixedly connected to a mounting plate, and the mounting plate is fixedly connected to a controller, and a detection piece corresponding to the controller switch is also hinged at the bottom of the mounting plate.

[0007] Optionally, in some embodiments, the side surface of the hook is threadedly connected with a locking bolt corresponding to the adjusting rod.

[0008] Optionally, in some embodiments, the bottom blowing furnace feed interruption prevention device further includes a vibration motor, wherein the vibration motor is fixedly mounted on the side wall of the hopper, and the vibration motor is electrically connected to the controller.

[0009] Optionally, in some embodiments, the detection sheet is in a “√”-shaped structure, and a hinge column is provided at a bend of the detection sheet, and the detection sheet is hingedly connected to the mounting plate via the hinge column.

[0010] Optionally, in some embodiments, the detection piece is divided into a long end and a short end by the bend. When the mineral material is conveyed normally, the mineral material will lift up the long end of the detection piece, causing the short end of the detection piece to be away from the controller switch, and the vibration motor is in a stopped state; when the mineral material is conveyed abnormally, the long end of the detection piece falls due to gravity, causing the short end of the detection piece to contact the controller switch, thereby controlling the vibration motor to start.

[0011] The technical solution provided by this application may have the following beneficial effects:

[0012] The present application uses a detection piece to perform real-time detection of the mineral material conveying situation. When the mineral material conveying is abnormal, the detection piece automatically triggers the controller switch under the action of gravity, thereby turning on the vibration motor, and clearing the hopper through the vibration motor to ensure the stability of the mineral material supply.

[0025] See also Figure 1 In the process of smelting in the bottom blowing furnace, the ore 5 to be smelted needs to be added into the hopper 1 first, and the ore 5 slides onto the ore conveyor 3 under the action of gravity, and the ore conveyor 3 transports the ore 5 to the bottom blowing furnace for smelting. In order to prevent the ore 5 from sliding off the ore conveyor 3 during transportation, the conveyor belt of the ore conveyor 3 is usually concave, and guard plates 4 are provided on the left and right sides of the ore conveyor 3.

[0026] Since a large amount of smelting ore 5 is piled up in the hopper 1, the ore 5 at the bottom of the hopper 1 is easily agglomerated under pressure, causing the hopper 1 to be blocked and affecting the normal feeding. Therefore, the present application performs real-time detection of the supply situation of the ore 5. When abnormal supply of the ore 5 is detected, the vibration motor 2 is automatically started to clear the hopper 1, thereby ensuring the normal supply of the ore 5.

[0027] See also Figure 2 The bottom blowing furnace feeding and material interruption prevention device comprises a bracket 6, a hook 7, an adjusting rod 9, a mounting plate 10, a detection sheet 11, and a controller 12. Two adjusting rods 9 are symmetrically arranged, and a hook 7 is slidably connected to each adjusting rod 9, and a locking bolt 8 corresponding to the adjusting rod 9 is threadedly connected to the side of the hook 7. When in use, the position of the hook 7 can be adjusted by sliding. After adjustment, the locking bolt 8 is tightened to make the end of the locking bolt 8 press against the adjusting rod 9, thereby fixing the position of the hook 7. Figure 1 As shown, the bracket 6 is fixedly connected between the two guard plates 4 by screws. When the hook 7 is adjusted, it is hung on the bracket 6 to complete the fixation of the device.

[0028] In this embodiment, the adjusting rod 9 is made of a square steel tube, and a mounting plate 10 is fixed to the bottom of the adjusting rod 9 by welding. The mounting plate 10 is made of a steel plate. The two mounting plates 10 are symmetrically arranged, and a controller 12 is fixedly installed between the two mounting plates 10. A detection piece 11 corresponding to the controller switch 13 is also hinged at the bottom position between the two mounting plates 10.

[0029] like Figure 1 As shown, a vibration motor 2 is fixedly installed on the outer wall of the hopper 1, and the vibration motor 2 is electrically connected to the controller 12. An elastic controller switch 13 is provided on the controller 12. When the controller switch 13 is in a pressed state, the vibration motor 2 starts to dredge the hopper 1; when the controller switch 13 is in a pop-up state, the vibration motor 2 stops.

[0030] like Figure 3 As shown, the detection piece 11 is in a "√" shape, and a hinge column 14 is provided at the bend of the detection piece 11. The detection piece 11 is hinged between the two mounting plates 10 through the hinge column 14, and the detection piece 11 is divided into a long end and a short end with the bend as the boundary, as shown in FIG. Figure 4As shown, when the mineral material 5 is conveyed normally, the mineral material 5 will lift up the long end of the detection piece 11, causing the detection piece 11 to rotate around the hinge, so that the short end of the detection piece 11 is away from the controller switch 13. At this time, the controller switch 13 is in a pop-up state and the vibration motor 2 is in a stopped state; when the mineral material 5 is conveyed abnormally, the height of the mineral material 5 on the conveyor belt will decrease, and the long end of the detection piece 11 will fall due to gravity, causing the detection piece 11 to rotate around the hinge, so that the short end of the detection piece 11 contacts and presses the controller switch 13. At this time, the controller switch 13 is in a pressed state, and the vibration motor 2 is started to dredge the hopper 1.

[0031] Furthermore, the blockage of the hopper 1 may be complete blockage, in which case the supply of the ore 5 is completely interrupted, or partial blockage, in which case the supply of the ore 5 continues, but the supply volume decreases. When the hopper 1 is partially blocked, it may be difficult to detect by traditional manual detection methods, thus affecting normal smelting. The present application uses the detection sheet 11 to detect the supply of the ore 5 in real time. Only when the supply of the ore 5 is normal can the long end of the detection sheet 11 be lifted up, so that the short end is away from the controller switch 13; when the supply of the ore 5 is reduced or interrupted, the long end of the detection sheet 11 droops under the action of gravity, so that the short end is lifted up to contact and press the controller switch 13, and the vibration motor 2 is started.

[0032] During smelting, different types of mineral materials 5 have different demands, so the supply of mineral materials 5 needs to be adjusted according to actual demand. By adjusting the position of the hook 7, the height position of the detection piece 11 can be changed, so as to adapt to the detection of mineral materials 5 with different supply amounts.

[0033] Specific working process:

[0034] When the supply of mineral material 5 is normal, the mineral material 5 will lift up the long end of the detection piece 11, so that the short end of the detection piece 11 is away from the controller switch 13, and the vibration motor 2 is in a stopped state; when the supply of mineral material 5 is reduced or directly interrupted, the long end of the detection piece 11 droops under the action of gravity, causing the detection piece 11 to rotate around the hinge, so that its short end contacts and presses the controller switch 13, starting the vibration motor 2 to dredge the hopper 1; when the supply of mineral material 5 returns to normal, the mineral material 5 lifts up the long end of the detection piece 11 again, so that the short end of the detection piece 11 is away from the controller switch 13, and the vibration motor 2 stops.
