Description

Technical Field

[0001] This utility model relates to the field of material conveying technology, specifically to a port batching device that simultaneously achieves material mixing during transportation. Background Technology

[0002] The technical and economic indicators of blast furnace ironmaking are closely related to the stability of raw material composition. Production practice shows that a 0.1% decrease in the grade of iron-containing raw materials reduces fuel consumption in sintering production by 0.6%–1.2%, increases sinter production by 0.28%, increases pig iron production by 0.3%–0.6%, reduces the coke ratio in the furnace by 0.2%–0.46%, reduces iron slag by 0.46%, and reduces furnace dust by 0.8%. However, currently, steel plants often use ore raw materials from different sources and with diverse varieties, as well as due to the unstable composition of ore products. These raw materials are often mixed in type, with large fluctuations in composition and particle size, resulting in poor stability of raw material composition.

[0003] By blending the iron ore received at ports to improve the stability of its composition before smelting, the technical and economic indicators of blast furnace ironmaking can be effectively improved. Existing coastal ports have a very large capacity to receive iron ore, but their main functions are loading, unloading, storage, and shipping. In recent years, blending practices implemented at some ports have been limited to simple loader mixing or using two stacker-reclaimers to extract two different grades of iron ore from two stockpiles according to the designed hourly flow rate. These are then transferred by belt conveyors to a third stacker-reclaimer, where the two raw materials are mixed and piled together in the third stockpile. This method is called coarse blending, which results in a limited variety of ore types, poor blending effect, and uneven composition. If the plant does not perform pre-blending treatment during use, it can negatively impact the stability of the sinter composition, causing a decline in blast furnace performance.

[0004] Chinese patent application CN118341322A discloses a mobile mixing and batching vehicle, specifically a mobile, high-efficiency mixing and batching vehicle that can move freely and integrates weighing and mixing. Although this mobile mixing and batching vehicle can achieve the mixing function of iron ore raw materials in ports, there is still room for improvement. A typical issue is the excessive length of the device itself. This is because the entire device requires a long belt conveyor, which can only transport materials and cannot mix them. The materials still need to be unloaded into a mixer for mixing. Therefore, the entire device is too large and is suitable for large-scale operations.

[0005] In summary, there is an urgent need for a port batching device that can simultaneously achieve material mixing during transportation to solve the problems existing in the prior art. Utility Model Content

[0030] To facilitate understanding of this invention, a more comprehensive description is provided below, along with preferred embodiments. However, this invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this invention.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0032] Example:

[0033] See Figures 1-4 This embodiment provides a port batching device that simultaneously achieves material mixing during transportation, comprising:

[0034] The machine body 1 has parallel rollers 2 at both ends (the two ends refer to the receiving end and the unloading end), and a conveyor belt 3 is provided on the two rollers 2; the machine body 1 is provided with a protective cover 5, and the protective cover 5 has at least one receiving bin 7 at the receiving end, and the discharge port of the receiving bin 7 is located above the material conveying section of the conveyor belt 3.

[0035] A stirring assembly 6 is rotatably mounted on a protective cover 5 and located above the material conveying section. The stirring assembly 6 is used to stir the material on the material conveying section.

[0036] A striking component 10 is disposed on the machine body 1 and located below the material conveying section. The striking component 10 is used to strike the material conveying section from below.

[0037] Specifically, in this embodiment, the material conveying section refers to the section on the conveyor belt that carries and transports the material. After the material in the receiving bin falls onto the material conveying section, it moves together with the conveyor belt 3 to the unloading end.

[0038] In this embodiment, the material particles in the material conveying section are lifted by the striking component 10 striking the material conveying section, and the material on the material conveying section is stirred by the stirring component 6, thereby achieving mixing of the material during the conveying process.

[0039] Furthermore, when there is only one receiving hopper 7, only one type of material can be conveyed, and materials of different particle sizes can be mixed evenly by the stirring component 6 and the tapping component 10. When there are two or more receiving hoppers 7, multiple materials can be conveyed simultaneously, and different types of materials can be mixed evenly by the stirring component 6 and the tapping component 10. In this embodiment, there are three receiving hoppers 7, which can achieve the even mixing of three different types of materials.

[0040] Preferably, there are multiple stirring components 6 and multiple striking components 10, all arranged along the running direction of the material conveying section, thereby achieving multiple striking and stirring of the material on the material conveying section. In some embodiments, the stirring components 6 and striking components 10 may be alternately arranged in the running direction of the material conveying section, achieving multiple alternating processes of material lifting and stirring; similarly, in some embodiments, the striking components 10 may be arranged below the stirring components to achieve simultaneous and uniform stirring of the lifted material.

[0041] See Figure 3 The stirring assembly 6 includes stirring blades 6.1 and a rotating shaft 6.2. The rotating shaft 6.2 is rotatably mounted on the protective cover 5. The rotating shaft 6.2 has multiple stirring blades 6.1 arranged in the circumferential direction. During the rotation of the rotating shaft 6.2, the stirring blades 6.1 on it drive the stirring blades 6.1 to stir and mix the material on the material conveying section.

[0042] Furthermore, such as Figure 1 and Figure 2 As shown, at least one side of the conveyor belt 3 is fixedly provided with a toothed belt 4, and a gear 11 corresponding to the toothed belt 4 is fixedly provided on the rotating shaft 6.2. The toothed belt 4 and the gear 11 are meshed together. Therefore, during the movement of the conveyor belt 3, the toothed belt will move together. Since the toothed belt 4 and the gear 11 are meshed with each other, the rotating shaft 6.2 will rotate synchronously together. In this embodiment, toothed belts 4 are provided on both sides of the conveyor belt, and gears 11 are provided at both ends of the rotating shaft 6.2. That is, both ends of the rotating shaft 6.2 are provided with gears that mesh with the toothed belts. This arrangement allows the driving force to be transmitted simultaneously from both ends of the rotating shaft 6.2, which can ensure the smooth rotation of the rotating shaft 6.2.

[0043] like Figure 3As shown, the striking assembly 10 includes a second rotating shaft 10.1, a fixed rod 10.3, and striking blades 10.2 capable of elastic deformation. The second rotating shaft 10.1 is rotatably mounted on the machine body 1 and has multiple striking blades 10.2 arranged circumferentially thereon. The fixed rod 10.3 is fixedly mounted on the machine body 1 and is located near the material conveying section. The distance from the fixed rod 10.3 to the second rotating shaft 10.1 is less than the distance from the outer side of the striking blades 10.2 to the second rotating shaft 10.1. The back side of the material conveying section... The distance of the second rotating shaft is less than the distance from the outer side of the striking blade 10.2 to the second rotating shaft 10.1. During the rotation of the second rotating shaft carrying the striking blade, interference will occur between the striking blade 10.2 and the fixed rod 10.3, which will cause the striking blade 10.2 to undergo elastic deformation. When the striking blade continues to move with the second rotating shaft and passes the fixed rod 10.3, the striking blade 10.2 will recover its deformation under the action of elastic force, thereby striking the material conveying section and causing the material on the material conveying section to be lifted up.

[0044] Preferably, a second belt assembly 14 is provided between the second rotating shaft 10.1 and the first rotating shaft 6.2, so that the second rotating shaft 10.1 and the first rotating shaft 6.2 can rotate synchronously.

[0045] Preferably, in some embodiments, other forms of striking components 10 may also be used, such as: a striking rod is provided, the middle of which is rotatably mounted on the machine body 1. One end of the striking rod is responsible for striking the material conveying section, and the other end is connected to a driving component to realize the reciprocating striking motion of the striking rod on the material conveying section; the driving component can be a crank-connecting rod mechanism, which is hinged to the striking rod to realize the reciprocating striking motion of the striking rod; furthermore, when it is necessary to increase the striking range, a striking plate can be provided at the striking end of the striking rod, with the length direction of the striking plate parallel to the width direction of the conveying section, so that the striking rod and the striking plate strike the material conveying section, causing the material to be lifted.

[0046] like Figure 2 As shown, in this embodiment, a third belt assembly 15 is provided between the two rollers 2 on the machine body 1, and one of the rollers 2 is connected to the drive component; the third belt assembly can realize the synchronous movement of the two rollers 2, which can effectively avoid slippage between the rollers and the conveyor belt. The drive component here refers to an external drive component, preferably a combination of a motor and a gearbox.

[0047] like Figures 1-3As shown, the unloading end of the machine body 1 is equipped with a cleaning wheel 12, and a first belt assembly 13 is provided between the cleaning wheel 12 and the roller 2 at the unloading end. The cleaning wheel 12 is used to clean the surface of the conveyor belt to prevent impurities from adhering to the surface of the conveyor belt. Preferably, the cleaning wheel in this embodiment is a brush, and the first belt assembly 13 can realize that the cleaning wheel rotates synchronously with the roller.

[0048] like Figure 1 and Figure 4 As shown, a sliding plate 8 is provided on the protective cover 5. The sliding plate 8 is used to adjust the size of the discharge port of the receiving bin 7, thereby controlling the discharge volume and facilitating the control of the discharged material.

[0049] like Figures 1-4 As shown, in this embodiment, the protective cover 5 is connected to the body 1 by a connector 9. The protective cover 5 is suspended on the body 1, and the toothed belt 4 is located on the outside of the protective cover 5.

[0050] Preferably, the first belt assembly 13, the second belt assembly 14 and the third belt assembly 15 each include pulleys and a transmission belt. The pulleys are fixedly installed on the two shafts that need to rotate synchronously, and then the transmission belt is installed on the two pulleys, so that the two shafts can rotate synchronously.

[0051] Preferably, in this embodiment, the components that need to be rotated are all mounted on the fixed components via bearings. This is a conventional setup in the art and therefore will not be described in detail.

[0052] The technical solution applied in this embodiment is as follows:

[0053] When in use, raw materials are first put into each receiving bin 7. The discharge amount of materials in the receiving bin 7 is controlled by the insert plate 8. At this time, the drive unit drives the roller to move. The first belt assembly, the second belt assembly, the third belt assembly, as well as the toothed belt and gear meshing drive the stirring assembly 6, the striking assembly 10, the conveyor belt 3 and the cleaning wheel 12 to move together.

[0054] After the material falls onto the material conveying section of the conveyor belt, it moves with the conveyor belt. During the movement, the stirring component stirs the material, and the striking component strikes the material conveying section to make the material fly up, thereby mixing the various materials on the material conveying section and achieving the purpose of mixing materials while conveying them. After the cleaning wheel 12 rotates, it can clean the working surface of the conveyor belt 3 to prevent impurities from adhering to the surface of the conveyor belt.

[0055] The effect of applying the technical solution of this embodiment is:

[0056] The batching device in this embodiment can tap the material conveying section through the tapping component, causing the material particles on the material conveying section to be lifted up. The stirring component then stirs and mixes the material on the material conveying section, which can achieve uniform mixing of the material during the material conveying process, saving working time and improving the practicality of the device.

[0057] The batching device in this embodiment can adjust the discharge rate of the material in the receiving bin through the baffle plate, thereby controlling the material discharge rate and matching the discharge rate with the mixing rate to ensure the material mixing effect. The working surface of the conveyor belt is cleaned by the rotation of the cleaning wheel at the discharge end to prevent impurities from adhering to the surface of the conveyor belt.

[0058] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
