Abstract
Description
Technical Field
[0001] This utility model relates to the field of material conveying and dust prevention technology, and in particular to a feeding device and a coke powder production line. Background Technology
[0002] In the sintering production process of steel smelting, coke powder is an important fuel, and its efficient and stable transportation plays a crucial role in the smooth operation of the sintering process. High-angle belt conveyors, with their advantages of large conveying angle, large conveying capacity, and compact structure, have become commonly used equipment in sintering workshops for transporting coke powder after crushing. They can effectively save equipment floor space and meet the needs of large-scale material transportation.
[0003] However, the four-roll crusher has a square feeding channel with an excessively large feeding area and a large feeding volume, which is incompatible with the belt size. This causes material to easily fall outside the belt, and when it does fall onto the belt surface, it easily causes fine powder to scatter. Because the inclined belt conveyor uses a method similar to a bucket chain conveyor, it is difficult to seal the side plates of the hopper using traditional baffles. During coke powder transportation, a large amount of fine ash sprays out from both sides of the hopper, causing dust to permeate the work area, resulting in serious environmental pollution, affecting the overall production environment and air quality of the workshop, and significantly increasing the labor intensity of the workers. Currently, after each shift of crushing, at least two people need to spend about three hours cleaning up the fine ash sprayed from both sides of the hopper. This not only consumes a lot of manpower and time, but also poses a risk to the health of workers due to prolonged exposure to high dust levels.
[0004] Therefore, there is an urgent need to propose a feeding device and a coke powder production line to solve the above problems. Utility Model Content
[0005] The purpose of this utility model is to provide a feeding device and a coke powder production line, which significantly reduces the amount of coke powder ash sprayed out without affecting the normal operation of the inclined belt conveyor and the coke powder transportation efficiency. This reduces the working time and labor intensity of personnel cleaning the ash, improves the working environment of the sintering workshop, reduces dust pollution, enhances the environmental protection and safety of workshop production, and achieves clean and efficient transportation of coke powder on the inclined belt conveyor.
[0006] To achieve this objective, the present invention adopts the following technical solution:
[0007] A feeding device includes a hopper, a first guide member, a second guide member, and at least two buffer members. The hopper is disposed above the belt of a belt conveyor, and a feeding channel is formed at the lower end of the hopper. At least two buffer members are spaced apart in the feeding channel along the width direction of the belt, forming a feeding opening between adjacent buffer members. The first guide member and the second guide member are positioned opposite each other and spaced apart below the feeding opening along the belt running direction. The first guide member is inclined from top to bottom along the belt running direction to guide the material to the belt. The inclination direction of the second guide member is opposite to that of the first guide member to guide the material to the first guide member.
[0008] In some alternative embodiments, the projection of the lower edge of the second guide in the vertical direction is located between the upper edge and the lower edge of the first guide.
[0009] In some optional embodiments, the horizontal projection of the lower edge of the second guide member in the belt running direction lies between the upper and lower edges of the first guide member; and / or,
[0010] The projection of the lower edge of the second guide in the vertical direction is located at 1 / 3 to 2 / 3 of the distance between the upper and lower edges of the first guide.
[0011] In some alternative embodiments, the horizontal projection of the lower edge of the second guide in the belt running direction is located at 1 / 3 to 2 / 3 of the distance between the upper and lower edges of the first guide.
[0012] In some optional embodiments, a discharge port is formed between the lower end of the second guide and the first guide, and the length L of the discharge port along the belt running direction ranges from 25cm to 35cm.
[0013] In some alternative embodiments, the tilt angle α1 of the first guide relative to the horizontal direction ranges from 40° to 50°.
[0014] In some optional embodiments, the tilt angle α2 of the second guide relative to the horizontal direction ranges from 30° to 60°.
[0015] In some alternative embodiments, the distance between the lower end of the first guide and the belt ranges from 5cm to 10cm.
[0016] In some optional embodiments, both the first guide and the second guide are composed of multiple splicing blocks, and each splicing block is welded and fixed to the hopper or an adjacent splicing block.
[0017] A coke powder production line includes a crusher, a belt conveyor, and a feeding device as described in any of the preceding claims. The crusher is used to crush coke powder, the hopper is disposed at the output end of the crusher, and the feeding channel of the hopper is located above the belt of the belt conveyor.
[0018] The beneficial effects of this utility model are:
[0019] This utility model provides a feeding device and a coke powder production line, including a hopper, a first guide member, a second guide member, and at least two buffer members. The hopper is positioned above the belt of a belt conveyor, and a feeding channel is formed at the lower end of the hopper. At least two buffer members are spaced apart within the feeding channel along the width of the belt, forming a feeding opening between adjacent buffer members. The first and second guide members are positioned opposite each other and spaced apart below the feeding openings along the belt running direction. The first guide member is inclined downwards along the belt running direction to guide the material onto the belt. The second guide member is inclined in the opposite direction to the first guide member to guide the material onto the first guide member. By setting buffer members within the feeding channel, the feeding area of the channel is reduced, making the material feeding position more concentrated and preventing material from spraying out from both sides of the hopper. Furthermore, the buffer members can catch falling material, providing a cushioning effect. The material first falls onto the buffer members before entering the feeding opening, reducing the falling potential energy of the material and thus reducing the impact force when the material contacts the belt, thereby reducing material spillage. Simultaneously, a first guide member is installed below the discharge port, inclined downwards along the belt running direction. This first guide member acts as a buffer and guide, enabling the material to descend slowly and be conveyed in a directional manner, allowing the material to fall smoothly onto the belt, reducing the impact between the material and the belt, and further reducing spillage. Furthermore, a second guide member is installed at a distance from the first guide member, with the inclination direction of the second guide member opposite to that of the first guide member. This guide member directs the material towards the first guide member, ensuring that the material enters the belt via the surface of the first guide member, further improving the stability of the material discharge and the conveying efficiency. Through these features, the discharge device can significantly reduce the amount of coke powder and fine ash ejected without affecting the normal operation of the steep-angle belt conveyor and the efficiency of coke powder transportation. This reduces the working time and labor intensity of personnel cleaning fine ash, improves the working environment in the sintering workshop, reduces dust pollution, and enhances the environmental friendliness and safety of workshop production, achieving clean and efficient transportation of coke powder on the steep-angle belt conveyor.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.
[0026] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0027] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
[0028] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, 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. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.
[0029] In the sintering workshop, after the coke powder is crushed by the crusher, it is transferred by a steep-angle belt conveyor. Because the steep-angle belt conveyor uses a similar conveyor system to a bucket chain conveyor, it is difficult to seal the side plates of hopper 1 using traditional baffles. During the coke powder feeding and transport process, the coke powder impacts the belt 100, causing it to scatter and resulting in a large amount of fine ash spraying out from both sides of hopper 1, filling the work area with dust and causing serious environmental pollution.
[0030] like Figures 1-3 As shown, this embodiment provides a feeding device, including a hopper 1, a first guide member 2, a second guide member 3, and at least two buffer members 4. The hopper 1 is disposed above the belt 100 of the belt conveyor. A feeding channel 11 is provided at the lower end of the hopper 1. At least two buffer members 4 are spaced apart in the feeding channel 11 along the width direction of the belt 100, and a feeding port 5 is formed between adjacent buffer members 4. The first guide member 2 and the second guide member 3 are positioned opposite each other and spaced apart below the feeding port 5 along the running direction of the belt 100. The first guide member 2 is inclined from top to bottom along the running direction of the belt 100 to guide the material to the belt 100. The inclination direction of the second guide member 3 is opposite to the inclination direction of the first guide member 2 to guide the material to the first guide member 2.
[0031] By setting a buffer 4 in the feeding channel 11, the feeding area of the feeding channel 11 is reduced, making the material feeding position more concentrated and preventing the material from spraying out from both sides of the hopper 1. On the other hand, the buffer 4 can receive the falling material and play a buffering role. The material first falls on the buffer 4 and then enters the feeding port 5, which can reduce the falling potential energy of the material, thereby reducing the impact force when the material comes into contact with the belt 100, and thus reducing the phenomenon of material spillage.
[0032] Meanwhile, a first guide 2 is installed below the discharge port 5, inclined from top to bottom along the running direction of the belt 100. The first guide 2 can buffer and guide the material, realize the slow descent and directional conveying of the material, so that the material falls smoothly into the belt 100, reduce the impact between the material and the belt 100, and further reduce the spillage phenomenon.
[0033] In addition, the second guide 3 is arranged at a distance from the first guide 2, and the inclination direction of the second guide 3 is opposite to that of the first guide 2. This can guide the material to the first guide 2, ensuring that the material enters the belt 100 through the surface of the first guide 2, thereby further improving the material drop stability and conveying efficiency.
[0034] With the above settings, the feeding device can significantly reduce the amount of coke powder and fine ash sprayed out without affecting the normal operation of the inclined belt conveyor and the coke powder transportation efficiency. This reduces the working time and labor intensity of personnel cleaning fine ash, improves the working environment of the sintering workshop, reduces dust pollution, enhances the environmental protection and safety of workshop production, and achieves clean and efficient transportation of coke powder on the inclined belt conveyor.
[0035] Of course, the feeding device provided in this embodiment can also meet the feeding needs of other materials that are lighter in weight, finer in particle size, and prone to generating dust and ash. It is suitable for material transportation on various large-angle belts 100 or flat belts 100, and can effectively reduce the phenomena of material spillage, dust diffusion and fine ash spraying.
[0036] like Figure 2 As shown, in some optional embodiments, the projection of the lower edge of the second guide 3 in the vertical direction is located between the upper and lower edges of the first guide 2. This ensures that after the material leaves the second guide 3, it falls directly onto the effective guiding surface of the first guide 2, reducing the problem of material spillage caused by improper landing point. This allows the material to contact the first guide 2 in a stable posture and fall evenly and smoothly onto the belt 100 after being guided by it. This significantly reduces material spillage, improves the stability and operating efficiency of the belt 100 conveyor system, reduces cleaning and maintenance costs and material loss caused by material spillage, and ensures the efficient and orderly operation of the production process.
[0037] Furthermore, the projection of the lower edge of the second guide 3 in the vertical direction is located at 1 / 3 to 2 / 3 of the distance between the upper and lower edges of the first guide 2. This ensures that the material guided by the second guide 3 lands at an appropriate position on the first guide 2. This avoids both material accumulation due to an excessively high landing point and insufficient buffer distance due to an excessively low landing point. It can minimize the kinetic energy of the falling material and ensure efficient material feeding.
[0038] In some optional embodiments, the horizontal projection of the lower edge of the second guide 3 in the running direction of the belt 100 is located between the upper edge and the lower edge of the first guide 2, so as to prevent the material from falling directly from the gap between the first guide 2 and the second guide 3 onto the belt 100, and to ensure that the material is directionally conveyed to the surface of the belt 100 via the first guide 2.
[0039] Furthermore, the projection of the lower edge of the second guide 3 in the vertical direction is located at 1 / 3 to 2 / 3 of the distance between the upper and lower edges of the first guide 2, so that the lower end of the second guide 3 and the first guide 2 are appropriately spaced in the running direction of the belt 100. This ensures that the material is guided to the first guide 2 while avoiding material blockage due to the two being too close, thereby improving the material feeding efficiency.
[0040] In some optional embodiments, a material discharge port is formed between the lower end of the second guide member 3 and the first guide member 2. The length L of the material discharge port along the running direction of the belt 100 ranges from 25cm to 35cm, which can meet the material discharge requirements, ensure the material discharge speed, and prevent material blockage.
[0041] Optionally, the length L of the material discharge port along the running direction of the belt 100 is not limited to 25cm, 30cm or 35cm, and is not limited here.
[0042] In some optional embodiments, the tilt angle α1 between the first guide member 2 and the horizontal direction is in the range of 40° to 50°. Based on the mechanical principle, it can achieve the best balance between material buffering and guiding effect. It can ensure that the material slides down at a moderate speed, avoiding material accumulation due to too small an angle, and also avoid excessively large angles that cause the sliding speed to be too fast and generate impact and spillage. It makes full use of the buffering effect of the guiding surface of the first guide member 2 to effectively reduce the impact force when the material falls onto the belt 100.
[0043] Optionally, the tilt angle α1 between the first guide member 2 and the horizontal direction is, but is not limited to, 40°, 45° or 50°, and is not limited here.
[0044] In some optional embodiments, the tilt angle α2 between the second guide member 3 and the horizontal direction is in the range of 30° to 60°, which enables the material to obtain a suitable downward driving force on the second guide member 3. This can both avoid material accumulation due to too small an angle, thus providing guiding efficiency, and avoid material impact and scattering on the first guide member 2 due to too large an angle, thus further reducing dust.
[0045] Optionally, the tilt angle α2 between the second guide member 3 and the horizontal direction is, but is not limited to, 30°, 40°, 50° or 60°, and is not limited here.
[0046] In some optional embodiments, the distance between the lower end of the first guide member 2 and the belt 100 ranges from 5cm to 10cm. This ensures that after being buffered and guided by the first guide member 2, the material contacts the belt 100 smoothly at a low speed under the influence of gravity. On the one hand, this avoids the increased falling height and impact caused by excessive distance, thereby reducing dust dispersion and fine ash spray. On the other hand, it avoids the material accumulating at the end of the first guide member 2 due to insufficient distance, thus ensuring material transportation efficiency. In addition, the smaller drop distance concentrates the material drop point, further reducing material scattering, lowering cleaning and maintenance costs, and ensuring a clean production environment and efficient and orderly operation of the production process.
[0047] Optionally, the distance between the lower end of the first guide member 2 and the belt 100 may be, but is not limited to, 5cm, 8cm or 10cm, and is not limited here.
[0048] The first guide member 2 and the second guide member 3 can be located inside the feeding channel 11 or extend below the feeding channel 11, which is not limited here.
[0049] In some optional embodiments, both the first guide 2 and the second guide 3 are composed of multiple splicing blocks, and each splicing block is welded and fixed to the hopper 1 or an adjacent splicing block. Through the modular splicing structure, there is no need for large-scale modification or replacement of the existing hopper 1. Only the splicing blocks need to be installed at the corresponding positions on the hopper 1 according to the actual working conditions to quickly complete the addition or modification of the guide components, significantly reducing equipment modification costs and construction time. This is especially suitable for upgrading and optimizing existing production lines, significantly improving the practicality and engineering adaptability of the feeding device.
[0050] The structure is also highly flexible, allowing for the adjustment of the length and angle of the guide components according to different material characteristics and conveying requirements. Customization can be achieved by increasing or decreasing the number of splicing blocks, enhancing the equipment's adaptability to diverse working conditions and providing technical support for enterprises to achieve efficient and economical material conveying.
[0051] Furthermore, this embodiment also provides a coke powder production line, including a crusher, a belt conveyor, and a feeding device as described in any of the above embodiments. The crusher is used to crush coke powder, and a hopper 1 is located at the output end of the crusher. The feeding channel 11 of the hopper 1 is located above the belt 100 of the belt conveyor. The feeding device realizes the transfer of coke powder from the output end of the crusher to the surface of the belt 100. Without affecting the normal operation of the steep-angle belt conveyor and the coke powder transportation efficiency, it significantly reduces the amount of fine coke powder ash ejected, reduces the working time and labor intensity of personnel cleaning fine ash, improves the working environment of the sintering workshop, reduces dust pollution, and can improve the environmental protection and safety of workshop production, realizing the clean and efficient transportation of coke powder on the steep-angle belt conveyor.
