Description

Technical Field

[0001] This utility model relates to the field of carbon raiser preparation technology, and in particular to a discharge device for carbon raiser preparation. Background Technology

[0002] Carbon raisers are external carbon-enhancing raw materials used in steelmaking and ironmaking. High-quality carbon raisers are essential auxiliary additives for the production of high-quality steel. After calcination, carbon raisers help to remove waste generated during sintering; increasing the removal rate can improve production speed.

[0003] Traditional material discharge devices mainly consist of a hollow box and a conveyor belt inside the box. During discharge, material is typically fed into the box through a feed hopper, then transported by the conveyor belt, and finally discharged from the outlet at the bottom of the box. While this discharge rate is relatively fast, most of the material falls directly from the feed hopper onto the conveyor belt. Under the influence of gravity, the material constantly impacts the conveyor belt, which can easily cause damage.

[0004] To address this, Chinese Patent CN218618548U discloses a discharge machine for a calcining furnace used to prepare carbon raisers. This device uses two buffer plates fixedly installed between the feed pipe and the conveyor belt to buffer the material falling on the conveyor belt. However, this device has new drawbacks: 1. High maintenance cost of the buffer plates: The buffer plates are easily worn and require frequent shutdowns for replacement; 2. Limited discharge efficiency: The buffer plates extend the material path and the staggered and inclined arrangement makes it easy for material to accumulate.

[0005] Chinese patent CN220829086U discloses a discharge machine for a calcining furnace used in the preparation of carbon raisers. This device uses an inclined guide plate below the feed inlet, which, through a reciprocating mechanism, drives a sliding plate to move laterally back and forth, causing a striking mechanism to strike the feed inlet. This not only prevents material accumulation but also prevents material from falling directly onto the conveyor belt. However, the reciprocating mechanism (half-gear, rack and pinion) has a complex structure and high operating and maintenance costs. Furthermore, the reciprocating motion of the sliding plate may not evenly disperse high-speed materials.

[0006] Therefore, we designed a discharge device for the preparation of carbon raiser. Utility Model Content

[0007] In order to overcome the shortcomings of the prior art, this utility model discloses a discharge device for preparing carbon raiser.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A discharge device for preparing a carbon raiser includes a discharge box, a conveyor belt disposed within the discharge box, a feed hopper at one end of the discharge box and a discharge port at the other end, and also includes an inclined guide plate. The upper end of the guide plate is hinged to the bottom of the feed hopper via a hinge mechanism, and the lower end is provided with a drive wheel. The rim surface of the drive wheel has a plurality of protruding units evenly distributed circumferentially. When the conveyor belt is running, its surface periodically contacts the protruding units, causing the guide plate to oscillate back and forth around the hinge mechanism to disperse the impact of the material and prevent material accumulation in the feed hopper.

[0010] Furthermore, the tilt angle of the guide plate is 20°-40°.

[0011] Furthermore, the protruding unit is a hemispherical, dome-shaped cone, or dome-shaped cylinder structure, and the spacing between adjacent protruding units is 1 / 10 to 1 / 6 of the circumference of the drive wheel.

[0012] Furthermore, anti-overflow baffles are provided on both sides of the guide plate to prevent material from scattering laterally.

[0013] Furthermore, the surface of the conveyor belt is provided with anti-slip texture, which is a wavy or sawtooth structure.

[0014] Furthermore, the drive wheel is connected to the lower end of the guide plate via a rotating shaft.

[0015] Furthermore, the hinge mechanism includes a support shaft fixed to the bottom of the feed hopper and a rotating hook located on the upper end of the guide plate. The rotating hook is attached to the support shaft and can rotate freely around it.

[0016] Furthermore, two sets of rotating hooks are symmetrically arranged at the upper end of the guide plate. The rotating hooks are detachable and replaceable to adapt to the switching of the material receiving surface of the guide plate.

[0017] Furthermore, the upper end of the guide plate is provided with a U-shaped plate, and the handle of the rotating hook moves through the corresponding side plate of the U-shaped plate and is fitted with a buffer spring to buffer the impact when the guide plate receives material and swings.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. By utilizing the conveyor belt's own operation to drive the guide plate to oscillate back and forth, there is no need to configure additional motors or complex reciprocating mechanisms (such as half gears, racks, etc.), which significantly simplifies the device structure, reduces manufacturing costs and maintenance difficulty, and reduces energy consumption. At the same time, the oscillation frequency of the guide plate matches the running speed of the conveyor belt, and the material is evenly dispersed through periodic oscillation, preventing material accumulation in the feed hopper and ensuring that the material is continuously and smoothly transported to the discharge port, greatly improving discharge efficiency and production continuity.

[0020] 2. The rotating hook at the upper end of the guide plate is detachable, and the guide plate can be flipped to replace the hook, realizing the switching of the material receiving surface and extending the service life of the guide plate; the optimized design of the tilt angle (20°-40°) and the spacing of the raised units can adapt to the characteristics of different materials.

[0021] 3. The buffer spring installed between the rotating hook and the U-shaped plate can absorb the impact force when the guide plate swings and the material is received, reduce the impact of mechanical vibration on the device, and further improve the stability and durability of the equipment operation.

[0027] The present invention will be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention. In the description of the present invention, it should be understood that if terms such as "upper", "lower", "front", "rear", "left", "right" indicate orientation or positional relationship, they are only corresponding to the drawings of this application for the convenience of describing the present invention. It should be understood that if terms such as "end", "side", "end portion", "side part", "lateral", "longitudinal", etc. indicate orientation or positional relationship, they are only corresponding to the length and width of the corresponding component. That is, "end" indicates the head and tail area in the length direction of the corresponding component, and "side part" indicates the head and tail area in the width direction of the corresponding component. They are used for the convenience of describing the present invention and do not indicate or imply that the device or element referred to must have a specific orientation.

[0028] Example 1, in conjunction with Appendix Figure 1-3 A discharge device for preparing carbon raiser includes a discharge box 1, a conveyor belt 2 disposed in the discharge box 1, a feed hopper 3 disposed at one end of the discharge box 1 and a discharge port 4 disposed at the other end.

[0029] As needed, the surface of the conveyor belt 2 is provided with anti-slip texture, which can be a wave-shaped structure to enhance the stability of material conveying.

[0030] It also includes an inclined guide plate 5, which has an inclination angle of 30° (preferably 20°-40°) as needed. The upper end of the guide plate 5 is hinged to the bottom of the feed hopper 3 via a hinge mechanism 6.

[0031] In some possible implementations, the hinge mechanism 6 includes a support shaft 601 fixed to the bottom of the feed hopper 3 and a rotating hook 602 located on the upper end of the guide plate 5. The rotating hook 602 is attached to the support shaft 601 and can rotate freely around it.

[0032] Furthermore, in conjunction with the appendix Figure 4 Two sets of rotating hooks 602 are symmetrically arranged on the upper end of the guide plate 5. Specifically, one set of rotating hooks 602 extends upward and the other set extends downward. That is, when the upward-extending rotating hook 602 is engaged with the support shaft 601, the upper surface of the guide plate 5 faces upward; when the downward-extending rotating hook 602 is engaged with the support shaft 601, the lower surface of the guide plate 5 faces upward. The rotating hooks 602 are detachable and replaceable to adapt to the switching of the receiving surface of the guide plate 5. That is, when the guide plate 5 is deformed or the receiving surface is severely worn, the guide plate 5 can be turned upside down and the rotating hooks 602 replaced so that the guide plate 5 receives material from the reverse side.

[0033] A drive wheel 7 is provided at the lower end of the guide plate 5. Specifically, the drive wheel 7 is connected to the lower end of the guide plate 5 via a rotating shaft 10. A plurality of protruding units 8 are evenly distributed circumferentially on the rim surface of the drive wheel 7. As needed, the spacing between adjacent protruding units 8 is 1 / 10 to 1 / 6 of the circumference of the drive wheel 7.

[0034] Depending on the requirements, the protruding unit 8 can be hemispherical or domed conical.

[0035] When the conveyor belt 2 is running, its surface periodically contacts the raised unit 8. The drive wheel 7 rotates under the friction of the conveyor belt 2, causing the guide plate 5 to swing back and forth around the hinge mechanism 6. The swinging of the guide plate 5 can disperse the impact force of the material, prevent the material from directly hitting the conveyor belt 2, and at the same time prevent the material from accumulating in the feed hopper 3.

[0036] To prevent materials from scattering laterally, overflow baffles 9 are provided on both sides of the guide plate 5.

[0037] In some possible implementations, in conjunction with the appendix Figure 3-4The upper end of the guide plate 5 is also provided with a U-shaped plate 11. The handle of the rotating hook 602 moves through the corresponding side plate of the U-shaped plate 11 and is fitted with a buffer spring 603. The buffer spring 603 can absorb the impact force when the guide plate 5 receives material and swings, thus extending the service life of the device.

[0038] Example 2: A discharge device for preparing a carbon raiser, differing from Example 1 in that the protruding units 8 of the guide plate 5 adopt a dome-shaped column structure, and the adjacent spacing is adjusted to 1 / 6 of the circumference of the drive wheel 7 to increase the contact frequency with the conveyor belt 2. Simultaneously, the anti-slip texture of the conveyor belt 2 is changed to a serrated structure to further enhance the gripping force on the material.

[0039] Working principle: After the material enters the discharge box 1 from the feed hopper 3, it first falls onto the reciprocating oscillating guide plate 5. Since the oscillation of the guide plate 5 is driven by the conveyor belt 2, the material is evenly dispersed on the surface of the guide plate 5, slowing down the falling speed and avoiding direct impact on the conveyor belt 2. The dispersed material is guided by the guide plate 5 to the surface of the conveyor belt 2 and finally discharged from the discharge port 4. The oscillation frequency of the guide plate 5 is matched with the running speed of the conveyor belt 2, ensuring that the material accumulation problem is completely solved.

It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that this utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the above embodiments should be regarded as exemplary and non-limiting in all respects.
