Description

Technical Field

[0001] This utility model relates to the field of ferrous metal conveying technology, and in particular to a ferrous metal smelting material conveying equipment. Background Technology

[0002] Ferrous metal smelting materials mainly refer to various raw materials, intermediate products, and auxiliary materials used in the iron and steel smelting production process. The core components include iron ore and its processed products (such as sintered ore and pellets) as the source of metals, coke and pulverized coal that provide heat and act as reducing agents, fluxes (such as limestone and dolomite) used for slag formation and adjusting slag composition, and recycled scrap iron and steel. These materials are an indispensable material basis for iron and steel smelting, and their physical form (lumps, powders, granules) and chemical properties directly affect the subsequent smelting processes and efficiency.

[0003] Given the large volume of material flow, high continuity requirements, and harsh environment (high temperature, dust, and high drop) in the smelting process, ferrous metal smelting materials typically employ efficient, reliable, and adaptable mechanized and automated conveying devices. These devices are mainly various types of closed or semi-closed continuous conveying systems, designed to achieve stable and closed transportation of materials from the raw material yard to various smelting processes (such as blast furnaces, converters, and sintering machines), minimizing losses and dust generation, and meeting the conveying needs of high-temperature materials or specific process routes.

[0004] In the ferrous metal smelting process, it is crucial to efficiently and accurately transport various raw materials (such as iron ore, coke, limestone, etc.) from the storage area to the smelting equipment. However, existing material conveying equipment has significant limitations. Due to the uneven particle size distribution of raw materials, materials of different particle sizes are easily mixed during the conveying process. More importantly, the large-particle metal materials mixed in will directly enter the subsequent grinding process, which not only greatly increases the time of subsequent operations, but also seriously restricts the overall production efficiency. Therefore, we urgently need a material conveying equipment for ferrous metal smelting to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the existing technology that the inability to effectively screen ferrous metals leads to the entry of larger particles of ferrous metal into the next process, resulting in increased time and efficiency. Therefore, this invention proposes a ferrous metal smelting material conveying device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A material conveying device for ferrous metal smelting includes a frame and a conveyor belt mounted on the frame for conveying materials. It also includes a screening drum rotatably connected to the frame, the inlet end of which is connected to the outlet end of the conveyor belt via an inclined plate; three sets of screening holes are equidistantly arranged on the screening drum, the diameter of which increases sequentially along the axis of the screening drum; and at least three sets of receiving boxes fixedly connected to the upper part of the frame for feeding materials, with the opening ends of the three receiving boxes corresponding to the three sets of screening holes.

[0008] In order to drive the screening barrel to rotate, preferably, a drive motor is fixedly connected to the frame, and the output end of the drive motor is connected to the end of the screening barrel through a belt on a pulley. When the drive motor is working, the screening barrel rotates accordingly.

[0009] In order to separate and transport the ferrous metals after screening, at least three sets of conveyor belts are fixedly connected to the frame for transporting the screened materials, and the feed end of the conveyor belts is connected to the discharge end of the receiving box.

[0010] In order to improve the feeding speed, preferably, the three sets of receiving boxes are set at an angle, and the angle range is 30°-45°.

[0011] To ensure stable operation of the screening barrel, preferably, a stabilizing wheel is fixedly installed on the frame to assist the rotation of the screening barrel, and the stabilizing wheel abuts against the surface of the screening barrel.

[0012] To suppress dust, preferably, a dust collection chamber for dust collection is provided outside the frame.

[0013] Compared with the prior art, this utility model provides a material conveying device for ferrous metal smelting, which has the following beneficial effects:

[0014] 1. This ferrous metal smelting material conveying equipment uses a screening drum and three sets of screening holes with different apertures. When the drive motor starts, it can drive the screening drum to rotate. The stabilizing wheel on the frame rotates with the screening drum. Ferrous metals of different particle sizes are screened and classified through the three sets of screening holes with different apertures, thereby avoiding the transfer of ferrous metals that do not meet the size requirements to the next process, which would prolong the production and processing time and further improve the production and processing efficiency.

[0015] 2. This ferrous metal smelting material conveying equipment features a dust collection chamber that covers the entire frame. Combined with external dust collection equipment, it reduces dust in the conveying area, preventing dust from being generated.

[0016] 3. This ferrous metal smelting material conveying equipment, through the setting of receiving box and conveyor belt II, realizes the transfer of sieved granules, and can be used with feeding belt to feed granules that meet the size, while granules that do not meet the size are directly transferred to the collection area, thereby improving the conveying efficiency of granules and improving production accuracy.

[0017] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model saves subsequent operation time, improves production efficiency, suppresses dust generated during the transport of ferrous metals, and also achieves unified collection of unqualified particles.

[0023] 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.

[0024] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Example

[0025] Reference Figures 1-4A ferrous metal smelting material conveying equipment includes a frame 1 and a conveyor belt 2 installed on the frame 1 for conveying materials. A dust collection chamber 10 for dust collection is provided outside the frame 1. Here, the conveyor belt 2 is driven by a motor on the frame 1 to transfer the ferrous metal smelting materials. The dust collection chamber 10 covers the entire frame 1 and works with external dust collection equipment to reduce dust in the conveying area and prevent dust from being generated.

[0026] It also includes a screening barrel 3 rotatably connected to the frame 1. A drive motor 7 is fixedly connected to the frame 1, and the output end of the drive motor 7 is connected to the end of the screening barrel 3 via a belt on a pulley. When the drive motor 7 is working, the screening barrel 3 rotates accordingly. The feed end of the screening barrel 3 is connected to the discharge end of the conveyor belt 2 via an inclined plate 4. Three sets of screening holes 5 are equally spaced on the screening barrel 3. The diameter of the three sets of screening holes 5 increases sequentially along the axis of the screening barrel 3. A stabilizing wheel 9 for assisting the rotation of the screening barrel 3 is fixedly installed on the frame 1, and the stabilizing wheel 9 abuts against the surface of the screening barrel 3. Here, when the drive motor 7 is started, it can drive the screening barrel 3 to rotate. The stabilizing wheel 9 on the frame 1 rotates with the screening barrel 3. Ferrous metals of different particle sizes are screened and classified through the three sets of screening holes 5 with different diameters, thereby avoiding the transfer of ferrous metals that do not meet the size requirements to the next process, which would lead to an extension of the production and processing time, and further improving the production and processing efficiency.

[0027] It should be noted that the screening barrel 3 is designed to be inclined, and the angle between the screening barrel 3 and the upper part of the frame 1 is 30°. This allows the material to move due to gravity when the screening barrel 3 rotates.

[0028] Here, iron ore is used as an example, and the appendix is ​​referenced. Figure 1 The sieve holes 5 have diameters of 10mm, 20mm, and 40mm from left to right, which are used to screen iron ore particles of smaller or larger sizes. This avoids larger particles from taking a long time to reduce in the blast furnace, leaving unreacted cores, and potentially causing uneven material distribution. It also avoids smaller particles from reducing the permeability of the material column, which would lead to increased blast furnace pressure differential and decreased gas utilization. These smaller particles need to be collected separately for sintering or pellet production.

[0029] At least three sets of material receiving boxes 6 are fixedly connected to the upper part of the frame 1 for feeding material, and the opening ends of the three sets of material receiving boxes 6 correspond to the three sets of screening holes 5. At least three sets of conveyor belts 8 for conveying the screened material are fixedly connected to the frame 1, and the feed end of the conveyor belts 8 is connected to the discharge end of the material receiving box 6. The three sets of material receiving boxes 6 are set at an inclination angle of 30°-45°. Here, when the screened particles fall downward and enter the material receiving box 6, the inclined surface of the material receiving box 6 causes the particles to slide downward into the conveyor belts 8 for conveying to different positions, so that particles of different sizes are placed separately for easy subsequent use. It should be noted that the medium-sized conveyor belts 8 and the attached Figure 1 The conveyor belt 28 located in the middle can be directly connected to the feeding conveyor belt, which can ensure that the size of the granules entering the blast furnace for ironmaking is the optimal reaction particle size, thus ensuring sufficient reduction.

[0030] In this invention, the operator places the granules on conveyor belt 2 for transport. The granules fall into the screening barrel 3 through the inclined plate 4. The drive motor 7 drives the screening barrel 3 to rotate, and the granules are screened by screening holes 5 with different apertures. The screened granules fall downward into the receiving box 6, and with the help of the inclined inner wall, the granules slide onto the second conveyor belt 8 for further transport. The second conveyor belt 8 located in the middle can directly transport the granules to the subsequent feeding conveyor belt. The remaining two conveyor belts 8 can move non-compliant granules to the corresponding placement area for easy subsequent processing.

[0031] 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. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
