Description

Technical Field

[0001] This utility model relates to the field of metal refining technology, and in particular to a raw material conveying device for iron smelting. Background Technology

[0002] Iron smelting is the process of extracting metallic iron from iron-bearing minerals. Commonly used methods include the blast furnace method, direct reduction method, smelting reduction method, and plasma method. From a metallurgical perspective, iron smelting is the opposite of the natural process of iron rusting and gradually mineralizing. The former extracts iron from oxides, while the latter allows metallic iron to slowly transform into iron-bearing minerals. In the iron smelting process, raw material transportation is an essential step.

[0003] Regarding the ironmaking raw material conveying device disclosed in patent publication number "CN210762698U", a tensioning mechanism is provided inside the conveyor belt. This can, to some extent, prevent the conveyor belt from deforming due to the large weight of the ore raw material, thus affecting the conveying efficiency of the ore raw material.

[0004] However, in actual use, due to the large amount of dust on the surface of raw materials such as ores, this dust will be raised in large quantities during the conveyor belt transportation, raw material falling and transfer process. It will not only spread into the surrounding environment and cause pollution, but also adhere to the surface of components such as conveyor belts. Long-term accumulation will increase component wear and even cause component jamming, further reducing the efficiency of raw material transportation.

[0005] Accordingly, this application proposes a feeding device for ironmaking. Utility Model Content

[0006] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a raw material conveying device for ironmaking.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] Ironmaking raw material conveying device includes a conveyor, a buffer assembly and a dust removal assembly. A feeding box is fixedly connected to the conveyor, and a feeding hopper is connected to the feeding box. A support is fixedly connected below the conveyor.

[0009] The dust removal component includes: a vacuum cleaner;

[0010] The vacuum cleaner is fixedly installed on the feed box;

[0011] The buffer assembly includes: a buffer plate;

[0012] The buffer plate is rotatably connected inside the feeding box.

[0013] Preferably, the dust removal assembly further includes: a roller, a second guide plate, and a first guide plate;

[0014] The roller is rotatably connected inside the feeding box, the second guide plate is fixedly connected inside the feeding box, and the first guide plate is fixedly connected inside the feeding box.

[0015] Preferably, the buffer assembly further includes: a plurality of rubber blocks, gears, and half gears;

[0016] Several rubber blocks are fixedly connected to the buffer plate, the gear is rotatably connected to the feeding box, the half gear is rotatably connected to the feeding box, and a torsion spring is provided at the connection between the buffer plate and the feeding box.

[0017] Preferably, the tip of the second guide plate is attached to the surface of the roller cage, the gear is fixedly connected to the buffer plate, the gear meshes with the saw teeth on the half gear, a motor is fixedly installed on the outside of the conveyor, the motor drive shaft is fixedly connected to the conveyor drive shaft, and a transmission assembly is provided on the outside of the unloading box.

[0018] Preferably, the transmission assembly includes: a first transmission wheel, a second transmission wheel, and a third transmission wheel;

[0019] The first drive wheel is rotatably connected to the outside of the conveyor, the second drive wheel is fixedly connected to the outside of the half gear, and the third drive wheel is rotatably connected to the outside of the feeding box.

[0020] Preferably, the transmission assembly further includes: a first belt and a second belt, the first belt being wound around the outside of the first and second transmission wheels, the second belt being wound around the outside of the second and third transmission wheels, and the third transmission wheel being fixedly connected to the roller cage.

[0021] This utility model has the following beneficial effects:

[0022] 1. After the raw material is fed into the feeding box from the feed hopper through the dust removal component, the raw material rolls down the first guide plate to the second guide plate, and then slides down onto the roller cage. As the roller cage rotates, the raw material can roll and fall at the same time, the dust attached to the surface will be shaken off and collected by the vacuum cleaner, reducing the spread of dust during the falling process and reducing the impact on the environment and equipment.

[0023] Second, through the buffer assembly, when the half gear rotates, it can cause the gear to drive the buffer plate to rotate. When the sawtooth on the half gear leaves the gear, the buffer plate drives the gear to reset under the action of the torsion spring. This reciprocating motion can make the buffer plate swing continuously. When the raw material falls, it first contacts the rubber block on the buffer plate. The rubber block absorbs part of the impact force with its own elasticity. At the same time, when the buffer plate swings to one side, the raw material will be pushed to that side and fall with it. When the buffer plate resets and swings, it will drive the raw material on the other side to exert force, so that the raw material slides off the buffer plate in batches and at intervals onto the conveyor belt of the conveyor. This avoids the raw material accumulating in a large amount on the conveyor belt at one time and prevents the conveyor belt from jamming or wearing due to excessive load at one moment.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Example 1

[0030] Reference Figure 1 - Figure 3 The ironmaking raw material conveying device includes a conveyor 1, a buffer assembly, and a dust removal assembly. A feeding box 3 is fixedly connected to the conveyor 1, which serves as the mounting carrier for each assembly. The conveyor 1 is used to convey processed raw materials. A feeding hopper 4 is connected to the feeding box 3, which is the inlet for the raw materials to enter the device. A support 2 is fixedly connected below the conveyor 1, which supports the conveyor 1.

[0031] The dust removal assembly includes: a vacuum cleaner 6, a roller 61, a second guide plate 62, and a first guide plate 63;

[0032] A vacuum cleaner 6 is fixedly installed on the feeding box 3 to absorb the dust inside the feeding box 3; a roller 61 is rotatably connected inside the feeding box 3, which can drive the raw material to roll and shake off the dust; a second guide plate 62 is fixedly connected inside the feeding box 3, with its tip attached to the surface of the roller 61, to scrape off the dust on the roller 61; a first guide plate 63 is fixedly connected inside the feeding box 3 to guide the path of the raw material falling.

[0033] A motor 5 is fixedly installed on the outside of the conveyor 1. The motor 5 provides power to the device, and its drive shaft is fixedly connected to the drive shaft of the conveyor 1, which can drive the conveyor 1 to rotate. A transmission assembly is provided on the outside of the unloading box 3 to transmit the power of the motor 5 to other rotating parts.

[0034] In this embodiment, starting the motor 5 enables the conveyor 1 to start working. After the raw material is put into the feeding box 3 from the feeding hopper 4, the raw material rolls down the first guide plate 63 onto the second guide plate 62, and then slides down onto the roller cage 61. As the roller cage 61 rotates, the raw material can roll and fall at the same time, and the dust attached to the surface will be shaken off and collected by the vacuum cleaner 6, reducing the spread of dust during the falling process and reducing the impact on the environment and equipment.

[0035] Example 2:

[0036] Unlike Example 1, referring to Figure 1 - Figure 3 This embodiment also has the following further features:

[0037] The cushioning assembly includes: a cushioning plate 7, several rubber blocks 71, a gear 72, and a half gear 73;

[0038] The buffer plate 7 is rotatably connected inside the feeding box 3 and can rotate inside the box to buffer the impact of raw materials; several rubber blocks 71 are fixedly connected to the buffer plate 7 respectively, and their own elasticity assists in buffering; the gear 72 is rotatably connected to the feeding box 3 and can rotate on the box; the half gear 73 is rotatably connected to the feeding box 3 and can rotate on the box; the serrations on the gear 72 and the half gear 73 mesh, so that when the half gear 73 rotates, it can drive the gear 72 to rotate; the gear 72 is fixedly connected to the buffer plate 7, so that when the gear 72 rotates, it can drive the buffer plate 7 to rotate synchronously; a torsion spring is provided at the connection between the buffer plate 7 and the feeding box 3, which is used to drive the buffer plate 7 to return to its original position after rotation.

[0039] The transmission assembly includes: a first transmission wheel 8, a second transmission wheel 82, and a third transmission wheel 84;

[0040] The first drive wheel 8 is rotatably connected to the outside of the conveyor 1. The first drive wheel 8 is fixedly connected to the drive shaft of the conveyor 1 and can rotate synchronously with the operation of the conveyor 1. The second drive wheel 82 is fixedly connected to the outside of the half gear 73 and can drive the half gear 73 to rotate synchronously when it rotates. The third drive wheel 84 is rotatably connected to the outside of the feeding box 3 and can rotate outside the box.

[0041] The transmission assembly also includes: a first belt 81 and a second belt 83. The first belt 81 is wrapped around the outside of the first transmission wheel 8 and the second transmission wheel 82, and is used to transmit the power of the first transmission wheel 8 to the second transmission wheel 82. The second belt 83 is wrapped around the outside of the second transmission wheel 82 and the third transmission wheel 84, and is used to transmit the power of the second transmission wheel 82 to the third transmission wheel 84. The third transmission wheel 84 is fixedly connected to the roller cage 61, so that when the third transmission wheel 84 rotates, it can drive the roller cage 61 to rotate synchronously.

[0042] In this embodiment, when the conveyor 1 is running, the first transmission wheel 8 drives the second transmission wheel 82 to rotate, and the third transmission wheel 84 drives the roller 61 to rotate, so that the dust removal components work synchronously. At the same time, the second transmission wheel 82 drives the half gear 73 to rotate, which in turn drives the buffer plate 7 to rotate. When the sawtooth on the half gear 73 leaves the gear 72, the buffer plate 7 drives the gear 72 to reset under the action of the torsion spring. This reciprocating motion causes the buffer plate 7 to swing continuously. When the raw material falls, it first contacts the rubber block 71 on the buffer plate 7. The rubber block 71 absorbs part of the impact force with its own elasticity. At the same time, when the buffer plate 7 swings to one side, the raw material will be pushed to that side and fall with it. When the buffer plate 7 resets and swings, it will also drive the raw material on the other side to exert force, so that the raw material slides off the buffer plate 7 in batches and at intervals onto the conveyor belt of the conveyor 1, avoiding the accumulation of a large amount of raw material on the conveyor belt at one time, and preventing the conveyor belt from jamming or wearing due to excessive load at an instant.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto.
